Introduction

Final year project (FYP) is a two-semester long course offered in the both Communications and CIE (Computer and Information Engineering) programmes at the Department of Electrical and Computer Engineering as an integral part of the curricula.

It is divided into two parts which is called FYP1 and FYP2 with three (3) credit hours each. However, FYP shall be considered as a special subject which is intended to provide avenue to students to actualize their dreams as graduating engineers by integrating knowledge they have acquired in the first three years of study with their spirit for intellectual pursuit. It is expected that students will gain experience to develop skills of problem solving, team work, professional responsibility and technical report writing. These skills are essential for student who wants to succeed in their professional carrier as engineer.

Students taking FYP must be fully aware that FYP requires more time and efforts compared to other subjects. FYP is an avenue whereby students are expected to behave independently and responsibly with adequate supervision.

Specifically this course has specified the following learning outcomes (LO):

Upon completion of this course, students should be able to:

1. Plan for engineering project utilizing relevant engineering principles and theories to design, built, operate, simulate and analyze to develop new product or process.

2. Propose effective engineering solutions through the application of mathematics, science and engineering fundamentals.

3. Design experiments to collect, archive and interpret data in order to make relevant decision on the performance of a communication/electronic/computer product.

4. Evaluate specific engineering design in terms of the social, cultural, global and environmental responsibilities of an engineer.

5. Practice ethical and professional norms for the implementation of engineering projects. 6. Present technical and scientific findings effectively through written and oral mode with the aid of

multimedia tools.

Therefore, it is highly expected that students will carefully decide which project to take. The decision shall come from a full conscience of all the consequences and commitment required in order to complete the subject successfully.

This compilation of offered FYP titles is meant to provide students with essential information of the projects. It is expected that students will use it to find necessary literature to understand the subject before enquiring the respective candidate supervisors.

We pray to Allah S.W.T. that He guide all of us and give us strength to strive for goodness. We also pray to Allah that he guide our beloved students to excel in their completion of the FYP. May Allah accept all efforts spent in this endeavor and reward it as good deeds. Amin

SUPERVISOR

Anis Nurashikin Nordin (ECE) & Maizirwan Mel (BIO)

SUMMARY Electric cell-substrate impedance sensing (ECIS) method can be used as a valuable tool for real time monitoring of cell behavior such as attachment, mobility, and growth. Changes in impedance of the cells due to growth and attachment can be modeled as an equivalent circuit consisting of resistors and capacitors of both the cell culture media and the cells. Cell-based sensing techniques provide continuous and real-time measurements making it more efficient compared to existing methods of microscopic observation. In this work, a biosensor which measures the impedance in breast cancer cells, Michigan Cancer Foundation 7 or MCF-7 will be designed and tested. The biosensor will be designed and fabricated on a printed circuit board and combined with a small Teflon cell holder. Impedance measurements of the MCF-7 cells will be used to deduce the cancer cell behaviors in different environments. An electrical model of the cells will be developed and simulated. This electrical equivalent circuit will provide a theoretical electrical model of the biological cancer cells.

Design and development of a programmable photoresist spinner

SUPERVISOR

Anis Nurashikin Nordin (ECE)

SUMMARY Photolithography is a critical process in the manufacturing of silicon integrated circuits (ICs). The spinner is an essential device for the deposition of a uniform and well-controlled photoresist layer on top of the silicon wafer. To attain uniform layer thickness, it is crucial to have a high angular speed, which leads to a high centrifugal force that acts on the resist fluid to move away from the center of the substrate. The Programmable Photoresist Spinner improves the precision control of the angular speed and acceleration. This component will aid in the development of discrete silicon devices such as the ICs for the micro-fabrication purposes.

The program prompts the user for inputs and the Motorola 68HC11 / Intel 8088 processes high-level commands and outputs signals to the motor control subsystem. The system is designed to accept user inputs for key parameters such as speed, acceleration and spin times for a given load.

Influence of Velocity on the Handover Delay propagation at Road-Side Units (RSUs)

SUPERVISOR

Dr. Rashid A. Saeed

SUMMARY

In WLAN based vehicular communications the main challenge is the high velocity of the stations (STAs), which leads to frequent

handover between access points (AP), which called road-side units (RSUs). Many publications addressed the IEEE802.11 amendments

communication channel between AP i.e. 802.11f/r/s; however, all these standards struggle at high velocity scenario as in vehicular

communication scenario. Some other upper layers solutions has been implemented successfully in mobile-IP techniques, but this also

associated with unavoidable delay especially in the real time communication i.e. VOIP. In this project we will introduce a new field in

the TDMA frame for backbone communication. TDMA is used as an encapsulation protocol for CSMA/CA to avoid the delay

associated with contention in CSMA/CA. the influence of the velocity on handover will be studied for the previous solutions and

compared with the current proposals. The new scheme will be simulated in ns-2.

OBJECTIVES

1. To enhance the delay propagation associated with RSUs interworking

2. To reduce the influence of velocity in HO delay,

3. Improve the QoS for the real time applications.


2. develop a new scheme for RSU interworking,

3. simulate the developed scheme

4. Results discussions.

TITLE

Modulation Schemes in OFDM Systems

SUPERVISOR

Khaizuran Abdullah

SUMMARY

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier system which utilizes a parallel processing technique allowing the simultaneous transmission of data on many closely spaced, orthogonal sub-carriers. In addition, modulation techniques are significant to ensure that an OFDM symbol is mapped from binary to complex signal with amplitude and phase represented in real and imaginary number for transmitting the signal. On the other hand, the signal is de-mapped or extracted from complex signal to recover back the OFDM symbol in the receiver.

This project will consider an image application with comparisons of QAM modulations for Fourier and wavelet based OFDM systems. The experimental results about BER performances for different types of QAM modulations in OFDM systems will be obtained.

OBJECTIVES

1. To study the modulation schemes for OFDM transceiver. 2. To simulate OFDM techniques using MATLAB and observe the effect of using different modulation techniques. 3. To obtain the BER results with respect to different types of modulation schemes.

RESEARCH METHODOLOGY1. Literature reviewing 2. Studying types of modulation schemes in OFDM systems 3. Generating OFDM system using MATLAB 4. Performing BER results

Rain Rate Measurement for Microwave Attenuation Prediction in Malaysia

SUPERVISOR


SUMMARY Terrestrial microwave system is the backbone line for mobile communication industry. In tropical region particularly in Malaysia, rain attenuation is the major constraint for implementing microwave system above 10 GHz [1]. The high rainfall rate leads to outages that compromise the availability and quality of service, making this one of the most critical factors in terrestrial and earth-to-satellite link design. Therefore, to maintain the reliability of the system it is important to predict rain fade margin accurately. The rain intensity distribution is the only parameter which can predict the rain attenuation for microwave propagation. This project aims to measure real-time rain intensity and model its distribution in Malaysia.

Scintillation Measurement and Analysis for Ku-Band Satellite Signals

SUPERVISORDr. Md. Rafiqul Islam

SUMMARY Scintillation arising from scattering atmospheric refractive index discontinuities and resulting in random fades and enhancements of the received signals amplitude about a mean level is an important source of degradation especially on low-availability satellite communication systems operating at frequencies above 10 GHz [10] [11]. The mathematical complexity of the problem of turbulent scattering and the randomness of its occurrence necessitate a strong dependence on satellite beacon measurement to develop empirical models for scintillation prediction. Before using the measured raw beacon propagation data for scintillation studies, contributions to data fluctuations by other propagation factors must be excluded [11]. Based on the data analysis for tropical country that observed tropospheric scintillation in the short and long term experiment on earth space paths with moderate elevation angle. This project aims to measure real-time satellite signal from MEASAT3 and extract the scintillation data and analyze it.

OBJECTIVES

Cantilever Beam vibration into useful energy

SUPERVISOR

Sheroz Khan

SUMMARY Emerging application fields, the need to increase the life of electronic devices, increased computational capabilities that require more energy and drastic reduction in device volume have been drivers of this field. Power management and wireless connection are becoming major issues in many applications. Research communities all over the world are working to find solutions and harvesting methods to optimize the power issue in sensors with the specific goal of implementing autonomous sensors. We discuss these concepts and two examples: an autonomous sensing device and an energy harvester, capable to convert for us vibrations into energy.

The contactless working principle consists of an actuation principle based on a Lorentz force source: when forcing a sinusoidal current in a solenoid facing the movable structure, a variable magnetic induction (Be) is generated, and simultaneously it induces eddy current density in the conductive plate (J). The interaction between the currents and the radial component of the magnetic induction gives a force along the z-axis (Fz) of the structure implying displacement.

The detection principle is based on a second periodic current having a higher frequency with respect to the one previously mentioned and forced in a solenoid. The induced magnetic field creates eddy-current density in the conductive plate and generates a magnetic field Bs. The oscillations of the mass generate an amplitude modulation on the carrier signal, and the information can be extracted using a pick-up coil.

OBJECTIVES

1. To make an analysis to derive equations relating mechanical vibration of the beam into oscillating current. 2. To conduct measurement of designed system for obtaining data between vibrations and resulting current

oscillations. 3. To discuss and analyze the measurement results

RESEARCH METHODOLOGY1. Literature review 2. Design (including simulation) and fabrication of the vibrations to oscillations system 3. Measurement of conversion characteristics 4. Analysis of resulting data

SUPERVISOR

Sheroz Khan

SUMMARY The acquisition of ambient energy for powering small electronic devices such as watches, devices used hand for monitoring purposes in locations to which wiring accessibility is either hazardous or their maintenance is costly. No matter how little, but all such devices need batteries as sources for continuous supply of energy.

The acquisition of ambient energy into a usable form is called energy harvesting. Examples of this ambient energy include light, vibrations or oceanic waves, solar or wind energy. Energy harvesting can be employed on a small and a large scale depending on the application it is being used for. Small scale energy harvesting is used in watches, and other electronic components employed in animals and inaccessible locations for monitoring purposes.

Thermoelectric sensors are semiconductor devices that generate a usable voltage proportional to the difference in between the body and room temperature. Of course, in commercially available devices an array of such junctions is used for producing positive and negative terminals with a voltage difference of a required level. The project involves simulation using suitable software such as Cadence,

OBJECTIVES

SUPERVISOR

Sigit P.W. Jarot

SUMMARY Recently there is new research trend to enhance the security level of wireless communication systems at the physical layer. One of the approaches that recently proposed is by using channel pre-compensation in conjunction with cryptography. This scheme works with assumption that the channel state information is available in the transmitter side. Moreover, the CSI must be highly accurate and timely to follow the variation of the wireless channel.

This project will analyze several quantization schemes for the system, and evaluate the performance by using numerical analysis as well as computer simulations.

OBJECTIVES

1. To study the physical layer security design and algorithms 2. To study the design of physical layer security based on channel precompensation 3. To analyze the effect of quantization sheme using computer simulation 4. To propose some improvement scheme (if possible)

TITLE

Cooperative Jamming Scheme for Security Enhancement of Wireless Sensor Networks at the Physical Layer

SUPERVISOR

Sigit P.W. Jarot

SUMMARY Recently there is new research trend to enhance the security level of wireless communication systems at the physical layer. One of the approaches is by using cooperative jamming. In contrast with the conventional wisdom, in secure communications, interference cane be a potentially beneficial phenomenon if added to the system properly. Thus the legitimate entities in the wireless sensor network system can ask the help of other nodes to jam the eavesdropper from whom the information flowing in the system is to be kept secret.

This project will analyze several scenarios of cooperative jamming schemes, and evaluate the performance by using numerical analysis as well as computer simulations.

OBJECTIVES

1. To study the physical layer security design and algorithms 2. To study the design of physical layer security based on cooperative jamming 3. To analyze the performance of cooperative jamming (i.e. security aspect) using computer simulation 4. To propose some improvement scheme (if possible)
