TEAM #2: FORCE FEEDBACK MECHANISM FOR A FLIGHTCONTROL YOKE

• Team members: Matthew Adams, Matthew LeFort, Yuka Matsuyama, Natalia Nguyen

• Adviser: Dr. Cristina DavisFlight simulators allow pilots to gain preparatory flightexperience,andaflightcontrolyoke isanessentialpartofthat process. Although there are many commercially available flightcontrolyokes,thegoalofourprojectistomakeoneforuseoutsideofflighttraining.Onespecificusewouldbetestingof aircraft designs in engineering laboratories. To achieve this,wemadeacheaper,moreaccessibleflightcontrolyokethatmaintainstheessenceofmoreexpensiveones.Ourflightcontrol yoke was designed to recreate a realistic control feel when maneuvering the elevator and ailerons. This feature is achieved by incorporating a force feedback mechanism with theaidofcommerciallyavailableflightsimulationsoftware.Two DC motors, one for the elevator and the other for the ailerons, are used for the force feedback mechanism to create variable, non-linear resistance on the user’s hand. Inputs from the flight simulation software are received byan Arduino microcontroller through a serial port, and then the data is processed by the Arduino. Based on the inputs from the software, the Arduino microcontroller controls the H-bridge, which regulates the voltage applied to each motor, and consequently varies the resistance on the yoke.

TEAM #3: FOIL SAMPLE CHANGER-HOLDER FOR CROCKER NUCLEAR LAB

• Department: Mechanical & Aerospace Engineering• Team members: Brian Lam, Jaime Quezada,

Brandon Whitney, Nathaniel Zululeta• Adviser: Dr. Cristina Davis

As part of a neutron beam line upgrade the Crocker Nuclear Laboratory is conducting, a new foil sample holder and

changer is needed to be designed, built, and tested. The foil samples will utilize the neutron beam to activate and produce designer radio isotopes for nuclear nonproliferation research and deterrence primarily conducted by the Lawrence Livermore National Laboratory. The requirements for the changer-holder are as follows: it must be remotely controlled, have the capability of moving a set number of quarter sized foil samples through the neutron beam line with high reliability and accuracy of repeat-ability, must be magnetic-free and radiation resistant, must have nothing behind the foil sample as the beam passes through, the entire system must be directly mounted onto the beam line pipe, and the foil samples must be able to be taken out of the holder with ease. The design and fabrication of the new sample holder-changer will make sampletestinghighlyefficient.Withminimaleffortgoingfromone sample to another, reduced testing time is achieved with minimal human interaction needed with the sample changer-holder and the beam line apparatus.

TEAM #4: WIND TURBINE BLADE TEST STAND• Department: Mechanical & Aerospace Engineering• Team members: Anthony Becerra Valdez, Antonio

Gomez, Christopher Harrell, Michael Taylor• Adviser: Dr. Cristina Davis

This project consists of designing a portable, compact, small electro-mechanicalteststandthatisabletoimpartflap-wisestatic loads to an instrumented wind turbine blade. The test stand must be able to load two blades to failure. A test stand was required because, recently, a blade broke off of the wind turbine on top of Bainer hall. The ACRES lab is in the process of making a new instrumented blade to replace the brokenone. Thebladewill bemadeof fiberglassandwillbeoutfittedwithcarbonnanotubesensorsinsidetheblade.The blade will need to be mounted to a stand and loaded to failure. This is done to make sure that the turbine blade will not fail under normal operating conditions and to verify that the instrumentation will work without compromising the strength of the blade. We have designed a test stand that has a steel, “T” shaped base and utilizes a stepper motor to apply force to the middle of the blade. The load will be measured using a load cell attached to the stepper motor and the data will be acquired using a National Instruments myDAQ and will be viewable on a laptop or desktop computer using labview. To measure the displacement we will be using a string potentiometer at the middle and at the end of the blade.

• Adviser: Dr. Cristina Davis, Dr. Kent Wilken, Dr. Stavros Vougioukas

Human workers are essential to strawberry harvesting because of their speed, accuracy, and judgment. However, manual strawberry harvesting requires workers to carry the strawberries to their collection points, often while traversing on a narrow and muddy path. Transportation time consumes up to 20% of working time for strawberry harvesters, and can be a safety issue. The primary objective of this project is to design, build, and test a harvest-aid robotic vehicle that willincreasetheefficiencyofhumanworkersbytransportingstrawberryflats from thefieldharvesters to the furrowendsquickly and safely. The robot should require neither external devicesnormodificationstothecurrentfieldenvironment,andoperate intuitively in order to minimize training. The robot will fitinasingle10-inchfurrowandbesmallandlightenoughto be carried by two persons (under 50 pounds). The shuttle uses four motors that are mounted to a lightweight aluminum frame, and includes a tray coupled with a suspension system to ensure that the strawberries are not damaged by rough terrain. For navigation, the robot uses hardware including a CMOS camera, several ultrasonic sensors, and encoders, as well as software including sophisticated image processing, filtering,andcontrol.Thisproof-of-conceptwillallowforfuturedevelopments including navigation software and hardware improvements,suspensionrefinement,androbotweightandmanufacturingmodifications.

TEAM #8: MOTION PLATFORM FOR FLIGHT SIMULATOR• Department: Mechanical & Aerospace Engineering• Team members: Richard Hampton, Walt

Tran, Jiabin Wang, Huan Zhao• Adviser: Dr. Cristina Davis, Dr. Stephen Robinson

The objective of this project is to create a small-scale motion platformfortheX-Plane10flightsimulator.Itwillbecomeanimportant learning tool because it can aid in the research of human-aircraft interaction and control. The motion platform simulatesthemotionsandforcesthatapilotwouldfeelinflight,and is able to achieve 6 degrees of freedom: pitch, roll, yaw, heave, sway, and surge. The platform is also able to simulate the shaking of turbulence. This platform is commissioned by the UC Davis Center for Human/Robotics/Vehicle Integration and Performance. The design is based on a Stewart platform and is driven by 6 high performance Hitec servo motors, and utilizes standoff hinges and heavy-duty aluminum motor arms to maximize performance. The servos are controlled by an Arduino Mega microcontroller with original software that reads angles and velocities from X-Plane 10 and translates them into motor angle positioning through Pulse Width Modulation (PWM). An Adafruit 16-Channel motor shield is used to drive the servos.

The primary objective of the senior capstone project is to design and demonstrate a proof of concept for a re-configurable desktop grinding machine. Currently, thebiggest challenges to manufacturing are: (1) shorter design to market timelines and product shelf-life (2) customization of products (3) fluctuations in demand and (4) changes inmanufacturing process technology. The purpose of developing are-configurableapproachtomanufacturingistoreduceoreliminate the said challenges by increasing the capabilities of individual machines. Two different designs are chosen, named LIL and GANTRY, to demonstrate the usefulness of a re-configurablegrindingarm—GANTRYmimicsconventionalgrinding machine designs for outer diameter grinding while LIL isastandalonearmwithfivedegreesoffreedomcapableofnavigatingcomplexgeometries.Eachconfigurationissuitedfor different types of grinding, but both are made of the same electronic and mechanical components in order to validate the re-configurable model. Programming coordination betweenelectro-mechanical components is critical to the success of the project and the greatest challenge. The Linkbot module, produced by Barobo Incorporated, is employed as the only programmable component of the grinding machine because it has a simple user to module interface and was invented at the University of California, Davis. Future work will involve streamlined programming and incorporating more robust modules, which can support realistic machining forces and vibrations.

TEAM #6: SANDIA NATIONAL LAB 5-AXIS CNC INSPECTION STATION

• Department: Mechanical & Aerospace Engineering• Team members: Elizabeth Kong, Minliang

Lin, Minh Chau Ngo, Allen Tse• Adviser: Dr. Cristina Davis

Complex machining operations cannot always be performed manually; therefore, CNC or computer numerically controlled machines are used. These machines generally take a g-code input and the on-board computer then converts it into machine tool paths to machine stock material. The CNC concept can also be translated to inspect the accuracy of manufactured parts. This is the goal of our project-- to build and design a CNC inspection station that has the capability to inspect objects with a variety of methods, over the exterior and interior surfaces of the objects. The sponsor for this project is Sandia National Laboratories. In order to to reach all surfaces of an object, 5 axes of motion are required--3 linear and 2 rotational axes. To inspect objects, various sensors can be used, such as a laser displacement sensor, a 4-point resistance measurement probe, and an ultrasonic probe. With such a wide variety of sensors, the inspection station is able to accommodate any off-the-shelf sensor via various sensor probe sizes. In order to accommodate larger objects, the inspection station has dimensions of 5.5ft X 4ft x 4ft and has a working volume of 36x36x48in. Open source CNC software, EMC2, is integrated to control the movement of the sensor probe.

TEAM #9: VIRTUAL REALITY TREATMENT FOR ADHD CHILDREN

• Department: Computer Science• Team members: Pei Guo, Diana Hsu,

Christopher Natividad, Jonathan Ngo• Adviser: Dr. Prem Devanbu

According to the National Institute of Mental Health (NIMH), AttentionDeficitHyperactivityDisorder(ADHD)isacommonmental disorder, affecting about 4.1% of American adults (ages 18 and above) and about 9.0% of American children ages 13 to 18. ADHD is divided into three presentations: Predominately Hyperactive impulsive, Predominately Inattentive, and Combined Hyperactive impulsive and Inattentive. Children exhibitingsymptomsofinattentivenesstendtofacedifficultyin school, often lacking the interest and self control required in order to effectively learn in a classroom setting. There is currently no cure for ADHD, although treatments do exist to help patients control their symptoms. The most common way that ADHD is treated is through prescription drugs such as Ritalin. These drugs, however, vary in effectiveness between users and often have negative side effects such as decreased appetite and sleep problems. Another means of treating ADHD symptoms is through behavioral therapy, which typically involves interacting with a counselor to learn how to control ADHD behavior. However, some researchers are considering the possibility of utilizing computers to develop toolstoincreasetheefficacyofbehavioraltherapy.Assuch,we are working with a group from the UC Davis MIND Institute in order to develop a virtual reality classroom. The goal of this project is to evolve behavior therapy by providing an immersive and interactive virtual environment that would allow subjects to practice controlling their behavior while recording runtime data to help quantify the effectiveness of the treatment.

TEAM #10: SEPSIS SUPPORT FOR GOOGLE GLASS• Department: Computer Science• Team members: Sushil Khadka, Jonathan King,

George Pantazes, Hoc Vo, Casey Wilson• Adviser: Dr. Prem Devanbu

This project aims to use the Google Glass technology to provide clinical data and intelligent decision support to doctors in cases of sepsis so they can provide informed, quality care that can potentially save lives. What is sepsis? Sepsis is an overwhelming immune response to infection, which damages its own tissues and organs. It can happen at any age, regardless of health condition and many times from seemingly benign incidents (e.g. a playground scrape). Severe sepsis strikes 18 million people every year, 750,000 being Americans and it have very high mortality rate that ranges from 28% to 50%. It is the leading cause of ICU deaths, accounting for 60-80% deaths in developing countries. It kills more than 6 million infants and young children worldwide every year. Diagnosis of sepsis is often delayed due to its difficulty to diagnose despite the rapid deterioration of thepatient. To summarize, sepsis is an ubiquitous omnipotent killer that literally and figuratively can cost us an arm anda leg, and does not discriminate against sex, ethnicity,

that can be used in many biological measuring aspects, this probe’s main advantage would be a great increase in time efficiency in not only the industrial workplace, but smallerlaboratories as well.

Gas powered air separation then removes almonds from similarly sized materials based on differences in density as they fall out of the trommel.

TEAM #16: AMPEROMETRIC GLUCOSE BIOSENSOR• Department: Biological & Agricultural Engineering• Team members: Mohammad Bakir, Ryan Kawakita• Adviser: Dr. Michael Delwiche, Dr.

Tina Jeoh, Dr. Ken GilesCurrently, there are no methods implemented in industrial settings for real time glucose monitoring during the conversion ofstarchandcelluloseintoethanol.Therearefivemajorstepsin this process: milling, hydrolysis, fermentation, distillation, anddehydration.Duringthehydrolysis(saccharification)step,amylase or cellulose enzymes are added in addition to water to the starch or cellulosic mixture, to convert this substrate into glucose. Then yeast is added to the reaction so the sugars may be converted into ethanol. One of the main issues with the saccharification and fermentation process ismonitoringthe concentration of glucose in the reactor before yeast is added. Discrete sampling methods are commonly used, where glucose concentrations in the samples are measured out by time intensive assays or analytical methods. We are proposing that a glucose sensor be used in place of such methods, where the newly engineered probe may take dynamic and real time measurements of glucose in multiple samples, rather than one at a time. This glucose probe can also be designed into a probe that measures other substrates. Instead of using glucose dehydrogenase as the active enzyme, alcohol dehydrogenase can be integrated onto the probe allowing for measurements of alcohols. Therefore, this probe can be applied to a number of biological reaction measurements. With a general design

TEAM #24: TORQUE VECTORING FOR ELECTRIC VEHICLE DRIVETRAINS

• Department: Electrical & Computer Engineering• Team members: Jeff Bouchard, John

Chy, Trevor Gibson, Tyler Lanham• Adviser: Dr. Andre Knoesen

The UC Davis Formula Racing team is tasked with building a 2/3 scale full electric formula style racecar and competing against other universities around the world. The team’s design this year involves a dual rear-wheel motor system, so our senior design project is to implement a torque vectoring control algorithm. Torque vectoring involves a sensor array on the vehicle collecting data on its current state, using things like throttle position, steering angle, wheel speed, tire temperature, etc. And using this information to influence acontrol loop dynamically allocating power to the drive wheels. Torque vectoring drastically improves vehicle performance and efficiency by reducingwheel slip and resolving driverturn request, and is the cutting edge in electric automotive technology.

movement and muscle development. There are four types of SMA which are determined by the age of onset. Death of the motor neurons debilitates the function of the major body organs. There is no existing cure for SMA. Patients with SMA often require the use of life-sustaining medical devices. Thus, their only method of transport currently available is a standard wheelchair at a reclined or supine position in which they must carry a mechanical ventilator, a gastrojejunal (GJ) feeding tube, and a pulse oximeter. Due to his constant dependency on these devices, outside access is often extremely limited to these patients. The objective for this project was to develop a transport system that would better accommodate SMA patients. The new transport device will allow for: outdoor use, be lightweight, easily turnable and pushable, accommodate and provide easy access to medical equipment, correctly and comfortablyfitapatientatabout10yearsofage,allowforadequate visibility from the inside, provide protection from the environment, and recognize safety considerations. The design will give SMA patients access to outdoor environments and allow them to meet other children their age which will improve their overall quality of life.

TEAM #28: WOUNDED VETERAN MOBILE DOG KENNEL• Department: Mechanical & Aerospace Engineering• Team members: Chris Cavoto, Kelley

Lunquist, Jason Petersen, Kyler Steele• Adviser: Dr. Cristina Davis

At the Veterans Affairs Hospital (VA) in Mather, CA, the increasing amount of veterans who bring their dogs with them to the emergency room has resulted in 1) unsupervised animals roaming the hospital and 2) patients being turned away due to lack of accommodations. To allow the health professionals at the VA to focus on patient-centric care, Michael Dion (RN at VA Hospital) proposed the team’s project objective: to design, build, and test a prototype dog kennel for use by wounded veterans’ companion dogs. The kennel must be lightweight, collapsible for storage in a coat closet, easy to clean, easy to move, and quiet when in motion - while staying under budget. In an effort to assist both the VA and its patients, the team designed an aluminum dog kennel fashioned with swivel casters, an adjustable height handle, and hypoallergenic cushions. The kennel is capable of holding large breed dogs to ensure that all patients will have the opportunity to receive care, regardless of the size of their dogs. The kennel also allows the patient to make visual and physical contact with their dog through a rooftop hatch. The team believes that the kennel will be a great addition to the Veterans Affairs Hospital and could be a solution for other hospitals across America in providing better patient centric care.

TEAM #27: AXIAL FAN FOR SMALL WIND TUNNEL• Department: Mechanical & Aerospace Engineering• Team members: Marich Bardham,

James Fong, Christopher Large• Adviser: Dr. Cristina Davis

This project is to design, build, and test an axial fan drive system that interfaces with a wind tunnel to replace the current home-made axial fan, which is no longer fully functional. This design employs a four-bladed fan mounted to a central shaft, which connects to a gasoline engine via a pulley and belt drive train. The fan blades are enclosed in a cylindrical casing that changes shape to mate with the square exit of the wind tunnel. The primary driver in this design is safety, with a minimum safety factor of 2.0 across all components and interfaces. The secondary driver in the system’s design is performance, consisting of two parts: 1) producing air speeds of 20~70mph in the wind tunnel’s test section, and 2) keeping the tip clearance of the fan blades to a minimum.

TEAM #34: TOOLS FOR REPAIRING RECIPROCATING DUAL PISTON PUMPS

• Department: Mechanical & Aerospace Engineering• Team members: Daniel Gallo, Hoa

Huynh, Derek Tam, Lili Yin• Adviser: Dr. Cristina Davis

This senior capstone design project revolves around the creation of custom tools and methods for rebuilding GAST reciprocating dual piston pumps at Crocker Nuclear Lab. The goal is to lower the 35% premature failure rate of the pumps that occurs after replacing its bearings. The bearings are presumed to fail due to improper installation into the pump frame. In addition, premature failure could result from misalignment of the frames with the pump coil and an uneven compression where the frame and coil connect together. Thus, the new tools should provide proper alignment of the frames relative to the coil, and an even pressure on the outer face of the frame in each press during reassembly. Also, the bearings need to be pressed evenly into the frames without damaging the cage prior to the frame-coil presses. The solution is the creation of five new tools for the rebuild process with anaccompanying operation manual. First, a bearing press block presses the bearings into the frames without exerting force on the bearing race. Next, a lower support plate with an adjustable sidewallaligns thefirst frame-coilassembly,andan upper press plate distributes pressure evenly. The finalframe-coil press uses the upper press plate again in addition to the lower press plate and the alignment system. All the tools utilize the compression force of the existing arbor press in our client’s shop, and are explained in the operation manual for the shop staff.

Common hand grips on wheelchairs are often ergonomically incorrect for caretakers taller or shorter than average height, which can lead to health problems such as back and neck pain. A standard wheelchair has hand grips to accommodate a person of height between 5’ 4’’ and 6’. To make the wheelchair hand grips more ergonomically correct, we designed adjustable hand grips for the optimal position for caretakers, allowing heights between 5’ and 6’ 4’’. The device consists of two sets of the same components. Each set consists of bent tubing and a clamp to attach to each wheelchair handle. The device can withstand stresses and forces from pushing or pulling on the hand grips. Wheelchair users are typically in one of two situations: short-term handicaps or ones that will last for the remainder of their lives. A person in a wheelchair for a short term will most likely be using a rental wheelchair from either a hospital or a wheelchair rental company. A personwhoisconfinedtoawheelchairforalongerperiodof time will mostly have a custom wheelchair to accommodate theirbodysizeorspecificneeds.Theseadjustablewheelchairhand grips are aimed at patients with short-term disabilities that require caretakers or hospital workers. These hand grips are designed to be used on standard sized wheelchairs, which do not accommodate bariatric, pediatric, or hemi-height wheelchairs. Caretakers will be more satisfied withtheir jobs due to the decreased likelihoods of developing pain or other physical injuries.

Most commercial handcycles are designed for on-road use only. The few off-road models available are aggressive, custom machines that often retail for well over $5000. The YOLOHandcyclefitsamiddlemarket-itcangooneasytomoderate off-road trails and costs below $1600. The YOLO Handcycle is a vehicle designed with local Davis trails in mind, one being the Putah Creek Riparian Reserve and Arboretum trails. We spent time familiarizing ourselves with the topic by sending out a survey to local handcycle users, speaking with them, doing online research, and riding handcycles ourselves.Usingauniversaljoint,wecreatedanefficientwayfor the user to simultaneously transfer power and steer.

The c-clamp screwsintothebaseofoursystem’sarm,aflexiblegooseneck,which spans the length of the hospital bed. The pressure pad is located at the end of the gooseneck arm and can be placed at any location relative to the patient with minimal effort by nurses. Our pressure pad functions via a simple switch circuit that is activated by pressure applied by the patient. The system interfaces with the hospital computer and a light at the nurses’ station is activated each time the patient presses the pad, alerting nurses to the patient’s need. Our product is easy to use and aids paralysis patients in getting the assistance they require, resulting in higher quality patient care and a safer hospital environment.

TEAM #38: MOVEMENT SYSTEM FOR OPTICAL TABLES• Department: Mechanical & Aerospace Engineering• Team members: Mengtao Guo, Xiaoxin

Ling, Luke Twombly, Zongyao Wang• Adviser: Dr. Cristina Davis

Optical tables provide a stable, vibration-free work surface designed to compensate for small disturbances for high sensitivity experimentation. These tables usually weigh thousands of pounds due to their high density and stiffness. Because of the weight factor, relocating tables becomes a costly endeavor, which requires hiring riggers to accomplish the relocation. The few existing hoists on the market cost upwards of $10,000. As a cost effective alternative, a new hoist system design is proposed to transport tables through hallways, over rough or inclined terrain, and into and out of elevators. Our design allows campus personnel to transport an optical table with a maximum weight of 6000 lbs, and with dimensions ranging from 3’x5’x6’’ to 4’x14’x12’’. The hoist system is designed to easily attach and detach from the table ends while the table is resting on legs or standing on edge. It is able to rotate the optical table such that the entire structurewillfitthrougha36”nominaldooropening.Throughthe use of two separate bottle jack hoists and clamps, the device adjusts to fit a range of different table lengths andthicknesses. A safety factor of 3 was used in the design analysis to ensure that the hoist system would not fail while loaded with an optical table.

TEAM #36: HYDROGEN ENRICHMENT OF INTERNAL COMBUSTION ENGINE

• Department: Mechanical & Aerospace Engineering• Team members: Jonathan Baxter,

Michael Hoch, Denis Legalov• Adviser: Dr. Cristina Davis

The applications of combustion are many and diverse, ranging from cars to fireplaces to power plants.While theraw process is well understood, the goal of more efficientcombustion research has taken off in the last few decades. One promising way to improve combustion is to use hydrogen enrichment with natural gas. Hydrogen is the most abundant element on Earth and is thought of as an ideal alternative fuel. The main reason why hydrogen is not currently used as an enricher is because of its lack of an infrastructure and readily available hydrocarbon fuels. The need for infrastructure can be mitigated through the use of steam reformation, which is used in our project. In the steam reformer, steam is mixed with methane in a catalytic reformer to form hydrogen that is fed backintothecombustionprocess.Thebenefitsofhydrogenenrichment allows for leaner operation, lower NOx emissions, andhigherefficiency,butoftenresultsinlowerpoweroutput.The synthetic gas is combusted in a small internal combustion generator and the exhaust heat produced is then used to heat the reformer.

TEAM #43: ROTARY ACCESSORY FOR ELECTRICAL DISCHARGE MACHINING

• Department: Mechanical & Aerospace Engineering• Team members: Diane Hascall, Martin

Hristov, Matt Kathan, Justin Ramirez• Adviser: Dr. Cristina Davis

Electrical discharge machining (EDM) is an advanced manufacturing process that uses electrical discharges to remove material from an electrically conductive workpiece. It allows for the machining of complex shapes and hard materials. Hill Engineering, the sponsor of this project, desired an accessory to facilitate circumferential cuts on cylindrical workpieces. Without such a device, this sort of operation is impossible using a wire EDM’s normal axes of movement. This engineering project involved the design of a rotary cutting accessory to be used with a submerged wire EDM. The design will be able to support workpieces weighing up to 10 pounds and with diameters as large as 5 inches. Workpieces will be rotated within a user-defined angularrange and within a frequency domain of 0.1-1 Hertz. The user will also be able to alter the applied torque to change the time of a given operation. This design is a proof-of-concept for these requirements. It has been designed to be compact and

device allow for lateral and vertical motions with respect to the frame. A height adjustment mechanism enables the device to accommodate users of various heights by changing the height of the support assembly. To encourage the user to move forward, the body supports can also be angled with respect to the base. This tilt is accomplished with the use of a screw located at the bottom of the height adjustment mechanism. To support the weight of user, a swivel seat is attached to the body support of the device. The design of the device is based on a current product, Kidwalk, which is not intended for users overtheageof12.Thesupportivewalkingdevicewillfillthecurrent void in the market for users 12 and up.

TEAM #45: VIRTUAL REALITY HEADSET MOUNTING SYSTEM

• Department: Mechanical & Aerospace Engineering• Team members: Fred Karlen, Justin Powell,

Jonathan Ryang, Peter Scheel• Adviser: Dr. Jae Wan Park, Dr. Cristina Davis

The Human/Robotics/Vehicle Integration lab is in need of a mount for a virtual reality system used for simulating the interior of various cockpits to train future pilots. The mount needs to attach two screens, appropriate electronics, and interchangeable lens housing to an HGU-55 Aircrew Fixed Wing Helmet without damaging the helmet. The design consists of four subsystems: screen housing, housing mounting, helmet mounting, and electronics mounting. The screen housing is cut in half horizontally so the screens can be slid and secured into. Four struts that accommodate a separate lens housing extend from each corner of the frame. We have picked a visor housing mounting system that has frames extending from the side edges of the screen housing to the sides of the helmet. The visor is attached to the helmet by a series of straps and hooks. Our product is adaptable to different head shapes and also able to accommodate people wearing glasses. The mount can move up and down the helmet by simply detaching the earpieces and placing them in a different position on the helmet. It can also move towards and away from the face by as much as four inches by an adjustable beam system. The primary helmet mounting system is 3-D printed with the exception of off-the-shelf screw and strap hardware, which we ordered from online sources.

It has been shown in cats that the blood supply to the eyes and brain can be reduced when the mouth is opened fully. The spring-loaded mouth gag currently used to hold the mouth open during endoscopic procedures does not limit the pressure applied to the jaw. As a result, cases of blindness or deafness have been reported following prolonged use of such a gag. In response to these complications, we have created a device that prevents the overextension of the jaw by holding the mouth open at a minimum width during endoscopic procedures. By inserting the patient’s canine teeth intothedevice,thedeviceisabletogripfirmlytotheteethand prevent slipping of the device from the mouth.

• Department: Biomedical Engineering• Team members: Kevin Cappa, Rachel Gurlin,

Joanna Quach, Alexander Summers• Adviser: Dr. Anthony Passerini

With post-mortem procedures at an all-time minimum, autopsies provide complete information about a disease or cause of death of a person. Virtual autopsy, also known as minimally invasive autopsy, provides an alternative to traditional autopsies. Through the combination of magnetic resonance imaging (MRI) and/or computerized tomography (CT), a full reconstruction of the body is digitally recreated. Once the body is imaged, sites of interest (SOI) that appear on the scan may need to be examined further. The CORe device is a minimally-invasive biopsy device that consistently samples layers of tissue in a cadaver in order to assist in the information provided by virtual autopsy. With a spring-loaded mounted system, the tissue sampler can be adjusted in three translational and two rotational planes to achieve the desired SOI. Various sampling depths can be achieved through height adjustments of the device. Lastly, to retrieve the tissue, a custom-made plunger pushes the tissue out of the bi-pointed needle.

• Adviser: Dr. Nael El-FarraPropylene,avolatileandhighlyflammableorganiccompound,has been used to manufacture n-butanol. However, not only is the propylene feedstock expensive, but the hydro-formylation of propylene requires the existence of synthesis gas which is a source of CO2 emission. In an effort to develop a more sustainable route of production, the method of the formation of n-butanol via the catalyzed dehydration of bio derived ethanol was used. This alternative was found to be less expensive as anhydrous ethanol is not required. The project includes generating flowsheets and simulations of the newchemical process using Aspen Plus Process software. Detailed economic evaluation for the conversion of ethanol to n-butanol was also performed to evaluate the economic feasibility.

In this project, a styrene production plant with an annual capacity of 800 million pounds was designed and simulated in Aspen Plus©. The catalytic dehydrogenation of ethylbenzene was modeled by a pseudo reaction. To determine the pseudo reaction stoichiometry, a total mass balance was applied to a laboratory reaction. The stoichiometric data was screened on the basis of a 60% minimum styrene yield and then ranked by its selectivity for styrene. To apply the selected isothermal laboratory reaction to an industrial scale process, a series of 3 adiabatic stoichiometric reactors with inter-stage heating were restricted to a 100 degree Fahrenheit temperature drop. Different separation schemes were developed around the RadFrac module in order to separate and purify styrene and key byproductsintherectoreffluent.Differentplantconfigurationswere then obtained by incorporating the reaction and separationsegments.Afinalplantdesignwaschosenthroughan economic evaluation of the different design possibilities. The strategies applied in this design project can also be applied to the design of other chemical facilities.

The production of this monomer can be produced using one of two industrial methods: the dehydrogenation of ethylbenzene or the through a propylene oxide-styrene monomer co-production process. In this project, we consider the design of a plant with the capability to produce 800 million pounds per year of the styrene monomer using the dehydrogenation of ethylbenzene located in Louisiana. The current market has a global production of 38 billion pounds per year of styrene monomer with increasing global demand, which suggests that such a plant will provide a valuable product in the US.

Butyrylcholinesterase (BuChE) is a bioscavenger for organophosphates, such as nerve agents (Sarin), pesticides, and herbicides (RoundUp). Small amounts of BuChE naturally occurinhumanblood(~2mg/L),butisinsufficienttodefendagainst organophosphate poisoning (requiring ~400 mg/dose), so there is an urgent need to develop a recombinant version (rBuChE) at an industrial scale.

TEAM #79: FEASIBILITY STUDY ON THE COMMERCIAL PRODUCTION OF ANTI-SARIN PHARMACEUTICAL IN RICE CELLS

• Department: Chemical Engineering & Materials Science

• Team members: George Correa, Richard Huber, Asun Oka, Kaylee Thatcher

• Adviser: Dr. Karen McDonaldAs the threat of chemical weapon use in politically unstable regions grows, so does the need for effective pharmaceuticals that prevent and protect against exposure. Butyrylcholinesterase (BuChE) is a human blood protein that protects against Sarin, a weaponized human nerve agent that has been used in a number of incidents, most notably the Tokyo subway attack and the Syrian civil war. Symptoms of exposure include muscle convulsions, brain damage, and death. BuChE irreversibly binds to Sarin, which prevents the toxin from reaching nerve synapses and allows it to be cleared from the bloodstream. This type of pretreatment would allow soldiers or aid workers to safely pass through regions where the risk of Sarin exposure is high. Currently, the only way to produce BuChE is from outdated blood plasma at a cost of $20,000 per dose. Our team has designed a biochemical processing plant that uses transgenic rice cells to produce over 60,000 doses of BuChE per year. Using SuperPro Designer®, we modeled upstream production and downstream processing for a batch operation facility. The goal of our project was to determine if large-scale production of BuChE using a transgenic rice system would lower the cost of production.

• Department: Mechanical & Aerospace Engineering• Team members: Daniel Enriquez, Jose

Giacoman, James Hawkinson, Daniel Jauregui, Yash Patel, Cory Simpson

• Adviser: Dr. Cornelius van DamThe aviation industry has seen a steady decline of turboprop-powered aircraft as the turbofan engine has matured and risen in popularity. Although capable of higher cruise speeds and higher altitudes, the turbojet engine consumes more fuel than its turboprop counterpart in regional transport applications. With the increased focus on environmental responsibility and the projected growth of the air travel industry, the opportunity exists for a fuel-efficient, high-performance, turboprop-powered aircraft capable of decreasing fuel consumption and alleviatingairtrafficcongestioncausedbytheoverabundanceof turbojets at high speeds and altitudes. The MD-130 is a dual-engine, 75-passenger, regional turboprop designed to operate at an altitude 31,000 ft and Mach number of 0.62 over a mission range of 1600 nmi or an economic mission range of 400 nmi. Featuring three lifting surfaces, the aircraft boasts increased control capabilities, increased structural integrity, and wider tolerance to center of gravity travel. Furthermore, strategic lift surface placement optimizes the aerodynamics of the MD-130 during cruise, thereby offering competitive performance characteristics when compared to conventional, tail-aft configurations. Finally, the 20% composite structuremakes the MD-130 one of the lightest planes in its class with payloads comparable to the competition.

• Adviser: Dr. Cornelius van DamIn short commuter flights that typically carry 35 to 90passengers, small regional jets powered by turbofans are slowly pushing turboprop powered planes out of the market. The reason behind this is two-fold. The turbofan regional jets have a higher cruise speed and altitude which often result in shorter flight times and a more comfortable flightexperience at those higher altitudes. More importantly, the turboprop planes are plagued with a very negative public reputation for being “old fashioned” and “part of the past”. The negative connotations that have grown on the turboprop are mainly due to the significantly less comfortable flightexperience. This is mainly due to the fact that turboprops are much noisier (propeller proximity to cabin), have smaller seats in comparison to their regional jet counter parts and have a less smooth cabin experience due to the relatively lower altitudes they cruise at. we are determined to bring the turboprop back to popularity by tackling all the problems that plague the current and older generation turboprop aircrafts. Turbopropsarenotonlymorefuelefficientthantheirregionaljet counterparts, but they also produce lower CO2 emissions and are less harmful to the environment. This is a win-win both financially and environmentally speaking. This is especiallyimportant at a time where global fuel reserves are dwindling and environmental awareness is popular in the public’s eye. Also the prices of gas have been exponentially rising and our turboprop aviation solution accounts for that.

Percutaneous endoscopic gastrostomy (PEG) tubes link a patient’s stomach to their external environment for direct feeding in an effort to bypass oral intake. Such situations where a PEG tube is used include neurological disorders such as dementia or stroke, injuries of the mouth or throat, and cancers of or near the esophagus. Classical PEG tubes used, while reasonably efficient at feeding the patient,involve leaving a large ‘handle’ hanging out of the patient’s abdomen. Though this ‘handle’ ensures the PEG tube does not fall back into the patient’s stomach, the ease of pulling it out involuntarily allows for a different set of potential complications.Current low-profilePEGdevices,alsoknownas PEG buttons, can only be installed at least month after installing a traditional PEG tube. This is because PEG tubes allow for the adherence of the stomach to the abdominal wall through natural healing, while PEG buttons cannot support this process. Installing a PEG button without this existing bond will cause the stomach to slip back into its original position in the body, which necessitates immediate corrective surgery.

• Department: Biomedical Engineering• Team members: Jesse Gipe, Andrew

Kessler, Edwin Leung, Spencer Tumbale• Adviser: Dr. Anthony Passerini, Martin Judenhofer

The combination of Positron Emission Tomography (PET) with Magnetic Resonance Imaging (MRI) is a new and exciting technology, with only one commercially available scanner. This hybrid imaging modality is powerful because it combines the soft tissue anatomical contrast of MRI with functional or metabolic imaging in PET. It is important to cool the PET detectors to prevent thermal noise from degrading the image signal. The current cooling system for the PET insert developed by the Cherry Lab takes a very long time to cool from room temperature to operating temperature. The cooling system also fails to maintain a stable operating temperature, which can further degrade the image. The objective of this project was to develop a cooling system that decreases total cooling time, and increases the temperature stability. This will allow the PET detectors to perform at their full potential, and provide higher quality images. One important consideration for our project is that no magnetic materials may be used in the MRI room. In addition, our solution must not cause any electromagnetic interference that will interfere with the accuracy of the MRI and PET systems. Our solution involves isolating groups of detectors into a cassette in order to provide better air distribution and isolation from heat sources. In addition, resistive heating elements are used to quickly regulate the temperature and maintain stability. This design allows for variation of temperature over groups or individual block detectors.

Millions of couples worldwide have difficulties trying toconceive. These couples are not necessarily clinically infertile, but instead have difficulty timing intercourse toachieve pregnancy. Failure to conceive can lead to serious psychological distress and lowered life satisfaction. Since the menstrual cycle fluctuates monthly, women use fertilitymonitoring devices to identify when they ovulate. Knowing the day of ovulation is crucial, because women are only fertile within a three-day window prior to ovulation. Current fertility monitoring devices on the market do not define the fertilewindow early enough or accurately enough to effectively help couples time intercourse. In fact, popular basal body temperature devices actually identify ovulation one day after it occurs. Our design team is developing the Couple’s Fertility Monitor to help couples and clinicians overcome the limitations of existing devices. Utilizing a novel sympto-thermal method and proprietary algorithms, our device will predict ovulation within a 24 hour window 5-7 days in advance. In order to foster couple involvement and improve accuracy, the device records measurements from both the woman and the man to

wastewater, rather than sending it to a wastewater treatment plant. Together, these systems will make the Cannery the pinnacle of sustainable water management.

TEAM #109: CONNECTING THE CANNERY• Department: Civil & Environmental Engineering• Team members: Naor Deleanu, Kenji

Frahm, Paul Matias, Joe Nguyen• Adviser: Dr. Deb Niemeier

Our project will focus on examining the current design for pedestrian/biker/vehicle traffic circulation,accessibilityandsafety. Our objectives will be to create new designs for The Cannery to minimize personal vehicle travel by improving access to public transportation, safety on walkways and bike paths and provide more bike parking. Another objective will focusonimprovingtheflowof trafficinandoutofTheCannery. This will be achieved by adjusting intersections and entry points to The Cannery.

TEAM #111: SUSTAINABLE DESIGN INC• Department: Civil & Environmental Engineering• Team members: Amanda Deering, Harfateh

Grewal, Dana Marler, Curtis Paget• Adviser: Dr. Deb Niemeier

Our aim is to provide a design that allows for recycled and reusable water to be collected through alternative sources such as a waste water treatment plant, rainwater harvesting and a dual pipe system. Due to of the water problems that are being faced by Californians, we have aimed to design a network that will ensure that treated water is available for residents to use on a daily basis. The waste water treatment plant on the site will not only reduce the impact on existing treatment structure maintained and operated by the City of Davis, but provide a localized solution to the problem of waste water by treating it in an environmental friendly way and using it for residential and irrigation purposes. Rainwater harvesting techniques will collect rainwater and the storm runoff and make it available for household usage as well. Similarly, changes in landscape, including introduction of plants and grasses that require less water, are native to the region as well as resistant to drought will also lower the water consumption at the site of Cannery.

The Canary Project is a new development in Davis, CA that provides an opportunity to develop a sustainable community that prove sustainable for future generations.

TEAM #105: THE CANNERY SUSTAINABILITY PROJECT• Department: Civil & Environmental Engineering• Team members: Nikolaus Carcha, Kristy

Chang, Joseph Guzman, Teason Miao• Adviser: Dr. Deb Niemeier

This project will address issues with the current Cannery Project Plan, and propose alternatives on one or two problems from a sustainability point of view.

TEAM #106: A COMMUNITY CONSCIOUS REDESIGN OF THE CANNERY PROJECT

• Department: Civil & Environmental Engineering• Team members: Christian Asuncion,

Allison Dyer, Alex Sturm, Hubert Xiao• Adviser: Dr. Deb Niemeier

This project aims to improve the sustainability of the proposed Cannery project whilst maintaining the housing capacity of the existing design. Our design was guided by three fundamental objectives: (1) Fostering a Sense of Community, (2) Reducing Greenhouse Gas Emissions, and (3) Optimizing Affordable Housing.

TEAM #107: THE GRADUATES• Department: Civil & Environmental Engineering• Team members: Christopher Armendariz,

PerrinJohal,SafiRizvi,AmarbeerSingh• Adviser: Dr. Deb Niemeier

Our group is analyzing the Cannery Project with respect to sustainable transportation design. We will review vehicle and bicycle connectivity in and out of the Cannery, and provide additional alternatives to improve safety and reduce vehicle congestion, and implement reliable bicycle routes. Additionally, a review of reducing vehicle use by increasing public transportation and car sharing. Our overall scope includes: better connectivity, safety, and reducing greenhouse gas emissions.

TEAM #108: DAVIS CANNERY WATER SUSTAINABILITY MANAGEMENT PLAN

• Department: Civil & Environmental Engineering• Team members: Luke Bromley, Yousuf

Kaleem, Trevor McGuire, Dylan Seib• Adviser: Dr. Deb Niemeier

The proposed Cannery development in Davis is designed to exceed current sustainability standards but more drastic efforts could be taken, especially in regards to water conservation and reuse. This project includes various elements that reduce potable water use and purify runoff. A combined dual pipe graywater and rain harvesting system will be used to irrigate landscaping and flushing of toilets. Stormwater runoff willbetreatedandleachfieldswillbeusedtodisposeofliquid

will generate enough energy to accommodate the expected usage of the residents and public and commercial facilities. We want to place PV panels in a way that can optimize solar exposureefficiencywhichinturncouldmaximizetheenergyproduction of the site. In placing a new system, land use may be altered to provide more opportunities for solar panel placement and energy generation. Rearrangement in the housing, public, and mixed-use areas may occur to optimize PV panel usage.

TEAM #117: SUSTAINABILITY & WATER CONSERVATION MEASURES: PURPLE PIPES FOR CANNERY

• Department: Civil & Environmental Engineering• Team members: Daisy Huizar, Maria

Muñoz, Brandon Wang• Adviser: Dr. Deb Niemeier

In addition to the water conservation design measures for The Cannery Project, we propose to add a dual pipe system to enhance sustainability within residential and mixed-use units. In the dual piping system proposed, the demand of high-quality potable water would be reduced by maximizing the amount of non-potable water for every day use. By partnering with the Davis Waste Water Treatment Plant, we can take advantage of non-potable water to exceed the water sustainability standard set for The Cannery Project, as well as the City of Davis.

TEAM #118: REVISION OF THE CANNERY• Department: Civil & Environmental Engineering • Team members: Victor Lemus, Jon

Roldan, Khon Tram, Jocelyn Wong• Adviser: Dr. Deb Niemeier

Our project tackles two primary issues associated with the development of The Cannery: reducing GHG emissions an improving livability.

TEAM #119: WATER CONSERVATION OF THE CANNERY

• Department: Civil & Environmental Engineering• Team members: William Diaz, Ben

Hadick, Matt Havey, Allison Langius• Adviser: Dr. Deb Niemeier

There are several methods in which we plan to conserve water and resourcing water effectively within the Cannery. The implementation of a natural drainage system would help reduce a large amount of the water required for irrigating turf landscape. The development of a dual pipe water system would allow the use of reclaimed water and potable water for specific needs. Specialized water catch systems couldutilizecisternsandbotanicalcellsystemsforefficientuseofstorm water. Strategically designed educational and incentive programs would assist the community in making living choices and encourage smart water use practices.

TEAM #120: INVESTIGATION OF DIFFUSION

TEAM #112: THE CANNERY PROJECT• Department: Civil & Environmental Engineering• Team members: Shawn Blair, Michael

Ellison, Jesus Gonzalez, Frank Jesus• Adviser: Dr. Deb Niemeier

TEAM #113: SUSTAINABLE STREETSCAPING• Department: Civil & Environmental Engineering• Team members: Diana Chen, Daniel

Cimini, Raymond Nim• Adviser: Dr. Deb Niemeier

Although the Cannery currently uses standard streetscaping practices, this approach is not sustainable. The standard impermeable asphalt and concrete has a large carbon footprint and requires costly maintenance. Furthermore, the stormwater gutter and inlet system has large startup costs. By implementing Low Impact Development (LID) practices--including permeable materials, bio-swales, and more--this project improves the streetscape in sustainable, economical, and aesthetically pleasing ways.

TEAM #114: JAR INC. CANNERY PROPOSAL• Department: Civil & Environmental Engineering• Team members: Raymond Chiang, Alexandro

Reyes Murillo, Juliana Walton, Kevin Yoshiki• Adviser: Dr. Deb Niemeier

of diffusion bonding of NiFe alloys as an alternative to the current processing methods for creating the NiFe housing to address issues related to processing cost and material quality. Current machining techniques are costly and introduce internal stresses and dislocations that degrade the magnetic properties of the alloy. Diffusion bonding, a solid state joining process that involves relatively low pressures and temperatures, can eliminate these issues by enabling cost-effective bonding of multiple layers of material, resulting in preservation of the bulk magnetic properties throughout the material. Bonding parameter optimization was carried out as a function of surface roughness of the starting stock and microstructural characterization of the quality of bonding was carried out using electron microscopy and ultrasonic imaging. Finally the magnetic properties of the prototype housing were tested. When taken together, the results strongly suggest the viability of diffusion bonding as a superior alternative to the existing processing method.
