(2013)
Ling, Yuan Zhou
Climate change is real and is happening. The change is made evident by the increasing occurrences and intensity of extreme events. As these extreme events are super- charged by climate change, what were once mere predictions have become reality. These extreme events pose serious threat to our society's infrastructures such as water resources, food resources, built environment, agriculture, health, energy and transportation. Essentially the study climate change consists of many components such as the vulnerability of our systems to climate change and extreme events, the impacts of climate change and extreme events, and the response policies, namely mitigation and adaptation. This is a preliminary study of a consolidative nature that attempts to connect the dots between climate change and extreme weather to study the impacts of extreme weather and climate change on infrastructures, the issues of water resources and built environment to climatic changes and of civil infrastructures due to climatic changes.

(2017)
Siti Rafidah Adnan
Sustainable development is being practiced to meet the needs of the present without compromising the ability of future generations to meet their own needs. In geopolymer, researchers use waste materials as the source of geopolymer. Over 65% of the crust of the earth consists of aluminosilicate minerals. Sediment is one of the major waste and sediment has the higher possibility for manufacturing of geopolymer due to their low cost and availability. The alkaline activator used in this preliminary study is Sodium Hydroxide (NaOH). 9 mix design have been tested L9 Taguchi Array. The four factors were NaOH (5M, 8M, and 10M), moisture (30%, 35%, and 40%), curing temperature (50°C, 60°C, and 80°C) and curing days (3, 7, and 14 days). The obtained results were evaluated by Design of Experiment (DOE) method to determine the optimum level of each factor. The optimum level of curing temperature was 80°C to achieve the maximum compressive strength. Meanwhile, the optimum NaOH concentration was obtained at 10M NaOH concentration. The moisture had no significant to determine the compressive strength. Furthermore, the optimum oven curing time was 72 hours. Microstructural behavior was also analyzed using Scanning Electron Microscopy (SEM) and X-Ray diffraction (XRD) in this study. Results show that the microstructural of ground sediment had a good potential as a source material in geopolymer. Thus, this research study focusing on NaOH activated ground sediment geopolymer.

A procedure for determining the true stress-strain curve over a large range of strains using finite element analysis for ductile materials
(2017)
Lakshmandas Kuna Sakar
The use of ductile materials in engineering applications are of monstrous proportions. They are used at a great deal within the manufacturing and transportation sectors of the world. The state at which these materials deform provide an insight at the workability of these materials. In order to understand the material, a comprehensive study on the deformation of material is required to fully actualize a certain material's workability. The simplest way to do so is the tensile test. The tensile test is a uniaxial test that simply works by measuring the force required to elongate a material by a specific length. From the tensile test, it is possible to obtain both engineering and true stress-strains. However, there comes a point of inconvenience as the material is stretched. Up till Ultimate Tensile Strength (UTS), the material obeys the uniaxiality of the tensile test and the material continues to stretch in a uniform manner. However, beyond the point of UTS, the material begins to neck. Necking occurs when the increase in strain hardening of a material is unable to compensate for the cross sectional area reduction of the material. With necking brings about complex stress components which starts to resonate to various fields of motion. This phenomena is termed stress triaxility. Hence the unvarying degree of freedom in the tensile test is considered to be obsolete due to stress triaxility. The tensile test is said to be inaccurate as it is only viable up till UTS. In this respect, this study sets out to correct the true tensile profile of ductile materials beyond UTS taking DP 600 High Strain Steel as the material probed in this study. For this purpose, a standard 2mm-thick sheet metal specimen are performed to establish a corrected tensile profile for this material. A experimental-numerical method is suggested in this study whereby detailed Finite Element simulation is done to replicate the events of a conventional tensile test. The true tensile profile is then obtain via a reverse engineering manner where by the true stress-strains of the material is made the input and the load-displacement of the material, the output. Iterations are done by altering the input values of the simulation until a load-displacement bend that suits the original experimental load-displacement data is obtained. This in return generates a new and corrected true tensile profile for the region beyond UTS and provides a definitive look at fracture mechanics.

Nurul Fatin Nadiah Abdul Aziz
Malaysia is one of the developed countries in South Asia. Proves that the local technologies in automobile industry growth widely such as Proton Holding and Produa Sendirian Berhad became one of the factors on selecting the title, a prototypic self-driving car using deep learning and computer vision. Besides that, the idea of this project also coming from many traffic congestions and accidents throughout the year recorded all over the world including Malaysia. Thus, to overcome this issue, this research project is purposed. This project focusing on three main goals which to train a set of data using neural network and achieve 70% of accuracy, design a self-driving car using remote-control (RC) car, Raspberry Pi, Pi Camera and Arduino and implementing a deep learning and computer vision and make it an autonomous RC car. Deep learning architecture was introduced to train set of data and achieve up to 70% accuracy. In this project, two models were presented. The models are You Only Look Once (YOLO) and Visual Geometry Group 16 (VGG16), the sub architecture from Single Shoot Multibox Detector. YOLO model is a model mean for training from scratch technique while VGG16 model is a model used for fine-tuning. As a result, VGG16 model is producing high accuracy compare to YOLO model. In designing a self-driving car using remote-control (RC) car, few components are involved. The components used are Raspberry Pi, Arduino, Pi Camera, RC car and Ultrasonic sensor. The connection of the elements is discussed in subsequence chapter under Methodology part. This experiment was differentiating between two design where the first design was constructed using commercial RC car available in the market and the second design was built by assembling mentioned components. The last objective is implementing a deep learning and computer vision and make it an autonomous RC car by simply combining the trained dataset with the designed RC car.

(2016)
Pragash Celvakumaran
This project highlights the application of solar photovoltaic (PV) scheme as a source of sustainable energy. The project is divided into two parts. First is the simulated design using LT Spice to model a design of solar based stand alone power plant consists of photovoltaic cells which produces DC voltage. Then, a boost converter is modelled in MATLAB Simulink to increase the output voltage to 230 Volts or 240 Volts depending on the region. The last and most important component is the inverter or to be precise, a PWM inverter simulated in MATLAB Simulink to convert the DC from rectifier to AC for load consumption. All the above simulations have a detailed calculation and description for all the design's parameters. For the second part, there will be a construction of a separate simple prototype hardware design to ensure the reliability of an inverter to test its competitiveness to supply power to load. The prototype consists of a battery which produces DC power instead of solar arrays to ease the testing of the inverter. The inverter's oscillator then converts the DC to usable AC power at 50 Hz for load consumption. The AC voltage is then step up to 240 Volts to power up a common household loads. Besides, a brief load calculations will be carried out to determine the power that can be produced and for how long from the hardware product. The final results are that both the parts are able to operate, proving the objectives of this project.

(2013)
Sughanthy Siva Andan Perumal
This thesis reports on the biomaterials and scaffold fabrication techniques in tissue engineering. There are different types of biomaterials and bone scaffolds fabrication techniques in tissue engineering applications. Tissue engineering is an non- conventional approach in creating artificial organs and tissues, by helping the patients to heal from bone fracture or organs malfunction by regenerating the damaged tissues. In this study, it involves the in-vitro seeding of specific human cells onto an extracellular matrix. Bioscaffolds are being developed by the various kinds of bioactive and biodegradable composite polymer in order to assist the attachment of cell, adhesion, proliferation, migrations and differentiations. The temporary bioscaffold is needed to serve as a template for the implanted cells and a physical channel to help the formation of the new tissues. Rapid prototyping technology such as direct polymer melt deposition (DPMD) method was used to fabricate scaffold design consists of complex internal architecture with high porous. Three design of scaffolds were created and each design subject to varying processing temperature. Polylactic acid (PLA) polymer was used to create the scaffolds. Scanning Electron Microscope (SEM) was used to characterize the surface and measure the pore geometry. The result shows that different type of pore size have different porosity percentage. Processing temperatures also affected the pore size and porosity of the scaffold. Further study to this project has a greater potential in the field of tissue engineering.
