ProblemBackground
Electrical power grids traditionally use AC voltages and this preferencehas also migrated to the development of AC microgrids. As an alternativeoption, DC microgrids have attracted increasing interest in recent yearsdue to the advantages of low converter cost and simpler control with noreactive power and synchronization concerns. In addition, a higher portionof energy sources (eg: PV's, Fuel cells) and energy storage technologies(eg: batteries, super-capacitors) are dc by nature. Various applications fordc microgrids have been reported, including all-electric ships, more-electric aircrafts, data centers, and residential complexes.
This project is a continuation of previous work.

Dr John Licari, john.licari@um.edu.mt, Dept. of Industrial Electrical PowerConversion
ProblemBackground Significant effort is being directed nowadays for increasing the integrationof renewable energy sources (RES) on power networks. RES, in general,produce a fluctuating output power due to the variation of the naturalresource. Energy storage has been proposed as a potential solution tomitigate resulting adverse effects on the network. Various storagetechnologies exist, with varying power– and storage– densities.Supercapacitors are short–term storage devices with high energy– andpower– densities along with other attractive characteristics, including longcycle life and high efficiency.

Co-supervisor (ifany):
N/A
ProblemBackground Despite the relatively simpler technology, thyristor soft starters still find alarge number of applications in industry. Soft starters limit the startingcurrent of induction motors, consequently also the starting torque henceavoiding excessive mechanical stress on the shaft. A number of softstarters tailored for specific applications are present on the market.

Problem
Background
Most Gyms use a lot of electrical energy to keep their surroundings cool due to
the heat loss from exercising persons. A small percentage of this energy can berecuperated by using the exercise equipment itself to generate electricity. Thisis especially true for equipment like rowing machines and exercise bikes wherepowers of around 500W can be obtained from alethic, fit and healthy persons.The project shall focus on how existing equipment could be retrofitted to makethe Gym greener and more energy efficient.

Conversion
Problem Background Domestic PV Systems are currently installed using a fit-and-forget approach inwhich these are permanently connected to the electrical grid. However for lowfeed-in tariffs it would make more sense to store the excess PV energy andconsume it during low generation periods. When making such a decision onemust keep in mind that the larger the storage, the more expensive is the system.Thus does it make sense to store energy in these scenarios? There is also thescenario where the customer has to be completely self-sufficient (rural areas),how can the energy be stored and used? What about the seasonal variation ofthe loads? This project shall address such issues and propose the mosteconomically feasible set-up by making use of a smart control method which willallow loads to be supplied with a certain pre-programmed priority. This projectshall be the ‘intelligence’ behind the on-going project of a grid-connected/stand-
alone PV system with load prioritization (In 2014/15 a wireless powermeasurement set-up with controllable loads was developed).
Project Objective(s): • Review of stand-alone systems with the possibility of grid-connection• Review of typical domestic electrical load profiles• High level modelling of the storage and grid connected system in SIMULINK• Modelling of seasonal loads of domestic house hold for varying population
(IES software)• Development of Control algorithm for optimization of energy usage,
optimization of energy cost and load prioritization for stand-alone operation.(With the aim to use the optimum energy storage size).

Co-supervisor (if any): Dr. Cedric Caruana, cedric.caruana@um.edu.mt, Dept. of Industrial ElectricalPower Conversion
Problem Background Wind energy is an intermittent source of renewable power due to the variabilitynature of the wind resource. This leads to a fluctuating power output which ishighly undesired for balancing supply and demand. On one hand, when theavailable wind power is higher than the load demand it can be stored to besupplied back when wind power is lower than the load demand. Batteries andsuper-capacitors are two types of energy storage devices currently beinginvestigated for such applications.

TOUCH LESS SENSOR FOR ROTOR POSITIONMEASUREMENT
Supervisor(s): Dr. Ing. Reiko Raute, reiko.raute@um.edu.mt, Dept. of IndustrialElectrical Power Conversion
Co-supervisor (if any): N/A
Problem Background Encoders or resolvers are usually used for a rotor position measurementof motors. These measurement devices are usually rather expensive andconsist of many fine mechanical components. Furthermore thesemeasurement devices need to be mounted to the rotor shaft with greatprecision. Any misalignment may cause serious damage. Manysemiconductor manufacturers recently developed magnetic positionmeasurement integrated circuits (ICs). These ASICs have dataprocessing features included and provide simple digital interfaces thatcan be directly connected to a micro controller. The advantage is thatthese devices are rather cheap and the position signal is touch lessdetected from a magnetic field.The task of this project is to build a small demo board with such a touchless position measurement IC and interface it to a microcontroller. Thisdemo measurement system shall be installed to a motor with encoder.
The performance of the rotor position measurement system shall becompared with the encoder result.

A MULTI-POINT DIFFERENTIAL GNSS SYSTEMSupervisor(s): Dr Ing. Andrew Sammut, andrew.sammut@um.edu.mt, Dept. of
Electronic Systems Engineering
Co-supervisor (ifany):
N/A
ProblemBackground
Todays ever expanding industry of personal navigators, smartphones andtablet computers seems to have trivialised the problem of positioningones location on the surface of the Earth, be it a dense city, out in a
desert or in the middle of the ocean. Yet accurate information regardingthe position of a body, be it in the aerospace, marine, automotive and ofcourse the consumer industry continues to be one of the most challengingproblems for design engineers. Realistically speaking, system thatprovide positional information with uncertainties below 15-20m RMS arehard to come by, even in complex systems which make use of multi-channel GNSS receivers, navigation grade inertial sensors and high-endDSP-based processors and demanding data-fusion algorithms. Thebottom line is that knowing one’s position with high accuracy in the sub-metre range is no easy feat, particularly when working within a tightbudget. Such accuracies are quickly becoming of high interest,particularly with the industries looking at high levels of automation suchas automatic taxiing, take-off and landing systems for aircraft, urbannavigation for automobiles and automatic ship berthing. This is even more
pronounced when considering unmanned and unsupervised applicationsthat evidently enforce more stringent requirements on reliabilityperformance.
ProjectObjective(s):
This project therefore addresses the matter of high accuracy positioningthrough the design of a low cost technique that solely makes use ofGNSS as the primary source for positioning. This is achieved through theapplication of differential corrections, which attempts to drastically reducethe common mode errors seen between the roving receiver and a numberof fixed reference base stations. The principle is that of having referencestation, with a known accurately surveyed position, take pseudorangemeasurements from the GNSS satellites in view and use this informationto generate correction signals which, once transmitted to the rovingreceiver through an adequate digital datalink, can compensate for the
errors when computing its position fix.
• Review the mathematical formulation involved in generating thecorrection signals (Final Year Project 2011/12)
• Review the hardware implementation of a typical base station androving station (Final Year Project 2013/14)
• Implement embedded code to enable single-point and multi-pointdifferential corrections, verify operation and compare the positionalaccuracy and performance.

IDENTIFICATION OF PCB AND SOLDER-JOINT DEFECTSTHROUGH X-RAY INSPECTION
Supervisor(s): Dr Ing. Andrew Sammut, andrew.sammut@um.edu.mt, Dept. ofElectronic Systems Engineering
Co-supervisor (ifany):
N/A
ProblemBackground
The era of electronic miniaturization has brought about with it the need forx-ray inspection of multilayer circuit boards and board assemblies in orderto investigate, in a non-destructive manner, the locations and quality ofsolder joints that cannot be inspected visually. The demands are various,ranging from the inspection of circuit tracks and buried vias on innercircuit board layers, as well as the inspection of solder joints, particularlyfor leadless packages, for confirmation of the quality of the solder joint. Inorder to achieve this, x-ray inspection systems typically having anexcitation voltage in the order of 100-200kV are required. Identifying thetypes of faults from the images acquired requires careful tuning ofexposure time and x-ray focal point. The resulting images requireinterpretation based on a good understanding of the physics involved in x-ray imaging.
ProjectObjective(s):
The purpose of this project is to investigate the quality of solder joints forsome of the most popular electronic packages including BGA, LGA, QFN,PLCC, chip-type as well as through-hole components and, from theimages captured, define criteria in order to distinguish a good solder jointfrom a bad one. This process involves the production of a set ofprototype boards onto which various components of different packagetypes are to be mounted. Components are then to be assembled usingdifferent temperature profiles and under different conditions in order tosimulate solder joints of various qualities. Following inspection under anx-ray microscope, the quality of the solder joints could be determinedthrough manual interpretation of the resulting images. The criteria to beconsidered include percentage voiding due to air bubbles, bridging of
joints due to surplus solder, dry joints typically due to contamination orinsufficient solder as well as misalignment of components. From theseimages, a set of criteria could be established allowing classification of anassembly as acceptable or defect.

ProblemBackground Research in computer graphics (CG) has been involved in the generationof synthetic imagery and historically, the approach adopted in CG is thecreation of scenes that are as realistic as possible, with algorithms lookinginto the physical optic laws to render the illumination effects on objectswithin the scene in a manner that is as close to reality as possible, withthe ultimate test being the ability of fooling a human judge into believingthat a computer generated image is a photograph of a scene.
The focus of CG has however shifted from the need of realism to theneed of representation and visualisation of complex scenes such thatthese can be communicated to observers as effectively as possible. Thus,the task of CG is no longer the creation of just realistic images but ratherthat of creating imagery that is useful and beautiful as well as physicallyrealistic. For this reason, CG algorithms are looking at cognitive sciences,
the fields of art and graphic design and illustration rather than optics.Here the challenge lies in the representing abstracted and structureinformation in a manner that is useful and aesthetic, hence the field ofnon-photorealistic rendering (NPR) .
One aspect of NPR is to create alternative representations of scenescaptured by digital photography. Here scene images are typically pre-processed using for example edge detection to find lines that exhibitchanges in illumination intensity across the scene. These may beweighted according to the cognitive and perceptual significance they havein the scene, using theories such as the Gestalt rules of perception.Artistic expression used by illustrators and artists, for example changes inline thickness according to the significance of the line, are then used torepresent these edges in the image, thus creating a new image from the
scene that is physically realistic but rendered in such a way that retainsonly the relevant structural shape of the scene.
ProjectObjective(s):
• To perform a literature review of NPR techniques• To review artistic cues that are used in line drawings• To use these cues to present an alternative representation of a scene.

Expected ProjectDeliverables:
• Literature review of existing NPR algorithms• Algorithm that obtains the structural information from a scene• Algorithm that represents this information in an NPR manner

CONTEXT CLASSIFICATION OF SCENESSupervisor(s): Ms. Alexandra Bonnici, alexandra.bonnici@um.edu.mt, Dept. of Systems

ProblemBackground
Scene Recognition is a key process in the human visual system, withhumans being able to understand the context of the scene presented tothem quickly and efficiently, irrespective of the number of objects, their
different poses, colours, shadows or texture.Scene recognition is traditionally performed by progressive reconstructionof the input scene fro local measures such as edges, corners andsurfaces, but more recently, researchers are suggesting that recognitionof real world scenes may be initiated by encoding the global configurationof the scene, bypassing all details and local features to focus on theholistic cues of the scene.
The human visual system uses both modalities: local and globalinformation from the scene are used to recognise the scene category. Forthis reason, representations of both the local and global features couldprovide for an improved machine categorisation of scenes. Local andglobal features may be obtained from Fourier-like transforms such as thediscrete cosine transform among others which use different sinusoidalfrequencies to represent different levels of detail in the image. Machinelearning algorithms, such as support vector machines can then be usedto learn the classification of the local and global features obtained fromthe images, such that new scenes according to the category to whichthey belong.
Such research has various applications in computer vision most notably inrobotic navigation systems, the systematic organisation of large imagedatabases as well as context based search and retrieval.
ProjectObjective(s):
• To obtain a set of local and global features from a scene• To be able to classify the scene according to some set criteria

Expected ProjectDeliverables:
• Literature review of suitable descriptors that can be used to describelocal and global features of a scene
• Literature review on machine learning algorithms that can be used tocategorise the scene features
• Algorithm that extracts some local and global discriminatory featuresfrom a scene
• Algorithm that provides the classification of scenes into theirrespective categories

OPTICAL MUSIC RECOGNITION OF PIANO SHEET MUSICSupervisor(s): Ms. Alexandra Bonnici, alexandra.bonnici@um.edu.mt, Dept. of Systems

ProblemBackground
The musical score arose from the need to record and pass from onegeneration to the other music expression in a manner that is more reliablethan aural tradition. Music notation has been adapted and improved over
the ages since the very first time that music was written down to themodern representation in use today. Music notation is highly symbolic,containing mixture of lines, note heads, markings for note durations andexpression, all arranged in such a manner that a musician mayunderstand the rhythm, pitch and expression of the musical score.
With cheaper digitisation media available, optical music recognition (OMR) became a researched area with value to musical and scientificcommunities alike. Optical music recognition opens opportunities forautomated and time saving methods for changing paper-based musicscores into a machine readable symbolic format that is used by musicsoftware, allowing the translation of the musical score into other notations,such as Braille, as well as increasing the interaction between the scoreand multimedia, allowing playback and musical analysis. Of particular
interest is the possibility of allowing a music scholar to assess his/herexecution of a musical piece with what is actually written in the score.
Optical music recognition requires the use of pre-processing techniquessuch as binarisation and line detection to enhance the quality of themusical score for further processing. This would typically involve musicalsymbol segmentation and recognition, using techniques such as HiddenMarkov Models . The musical symbols must the be re-organised intomeaningful groups such that the reconstruction of the musical notationmay take place, representing the musical score in a format such as MIDI which may be ported to musical software or digital instruments.
ProjectObjective(s):
• To understand the issues involved in optical music recognition inorder to develop algorithms that may extract the symbols present in a
musical score• To extract the information encoded within these symbols andrepresent it in formats that can be used by digital instruments orsoftware.
Project Resources N/A
Expected ProjectDeliverables:
• Literature review of existing optical musical recognition systems,including pre-processing techniques that can be used for musicalscores and symbol recognition algorithms that are useful forrecognition of musical symbols
• Algorithm that extracts symbolic information from printed musicalsheets
• Algorithm that changes this symbolic information into MIDI format

3D INTERPRETATION OF DRAWINGS WITH ARTISTIC CUESSupervisor(s): Ms. Alexandra Bonnici, alexandra.bonnici@um.edu.mt, Dept. of Systems

ProblemBackground
Drawings have an important role in communication of ideas to otherpersons. Sketches of 3D objects are however, potentially geometricallyambiguous, since the representation of drawn objects in the 3D space
may have multiple valid interpretations. Humans overcome theseambiguities, partly by using preconceived geometric concepts but alsothrough other cues that may be present in the drawing. To this extent,artists and designers often include artistic cues to help in the portrayal ofgeometric intent. Such cues may include the use of shading and shadowsas well as the use of thick, bold lines for object edges which are closer tothe observer and thinner lines for edges further away from the observer,thus introducing an impression of depth in the drawing.
Machine interpretation of pen-and-paper drawings is therefore aninteresting and challenging problem and attempts to create interpretationsof the sketched objects that is similar to the human interpretation of thesame sketch. In current research carried out within the department ofSystems and Control Engineering, the artistic cues are being used todistinguish between the different geometric interpretations of the edge,namely, distinguishing between convex , concave , and occluding edgesbased on the shading cues that are present in the drawing and labellingthe edges accordingly. While such a distinction serves to give an idea ofthe overall geometric shape of the drawing, the labels alone do notgenerate a 3D interpretation of the drawing.
These labels can however be used to provide an initial inflation of thedrawing and such an initial inflation may be used as an initial startingpoint in conjunction with other 3D interpretation algorithms described inthe literature to obtain the full 3D interpretation of the drawing. Suchalgorithms however, are based mainly on geometric constraints and donot take into consideration the artistic depth cues that are present in thedrawing. To this extent, the aim of this project will be to investigate howthese artistic depth cues can be used in conjunction with existing 3Dinterpretation algorithms to obtain 3D models from drawings that matchthe designer's intent.

• To understand the different depth cues that may be present in adrawing
• To use these depth cues to obtain a 3D interpretation of a drawing

Expected ProjectDeliverables:
• Literature review of existing 3D interpretation algorithms• A study of different depth cues that are used in sketches• Algorithm that obtains 3D models from the 2D sketches
