A Proxy-Assisted Routing For Efficient Data Transmission In Mobile Ad Hoc Networks / May Zin Oo, Zin Oo May
Student Works (2010-2019)
A new protocol, named Proxy-Assisted Routing for efficient data Transmission (PART), that uses a cross layer approach is proposed to route packets to a destination efficiently in Mobile Ad Hoc Networks (MANETs). PART limits the number of control packets with the aid of proxy nodes, adapts to route failures and avoids congestion quickly by broadcasting routing information within a predefined zone. It utilizes the address information of the Medium Access Control (MAC) layer to transmit unicast control messages and limit the broadcast zone. Only mobile nodes that are in this zone are allowed to broadcast routing information to reduce the …

Malaysia is a hot and humid tropical country that has yearly mean temperature between 24°C and 33°C and relative humidity between 70% and 90% throughout the year. Thus, overheating is a paramount problem in residential buildings. Although air conditioning can solve this problem, it will consume a large amount of electricity and also causes environmental problems. Moreover, the concern of sick building syndrome has resulted in a resurgence of interest in naturally ventilated rooms. The action of opening a window is the most intuitive and simple response to controlling overheating in a room. Even so, if the window opening dimension …

Biomass of various sources such as those of cellulosic and hemicellulosic contents were proven to produced bioethanol. This study focused on the production of bioethanol from waste fruits of grapes and apples using yeast Saccharomyces cerevisiae, which is viewed as a mean of reducing environmental pollution. High bioethanol production was obtained using yeast loading of 4 g/L at 32°C after 3 days of fermentation time producing bio-ethanol 13.1% (v/v) and 9.2% (v/v) in rotten grapesand apples respectively. Bioethanol yeild was observed to decreased with increasing fertmentation time beyond 3 days, probably due to microbial wastes such as CO2 that accumulates …

On the east and west orientations of the glazed buildings in the tropics where the solar altitude is low, the solar energy transmittance can not be effectively controlled by shading, except by blocking most of the glazed facades. Wherein, the daylight would be sacrificed. Based on this premise, to reduce the transmittance of solar energy without sacrificing daylight, the appropriate solution is the use of high performance insulated glazing system with spectrally selective coatings that distinguish between visible range (daylight) and infrared range (heat). Nevertheless, the drawback is its high capital cost. This study seeks to improve the control of …

This thesis focused on the synthesis and self assembly studies of compounds involving carbohydrates. Two different types of materials were studied, i.e. surfactants and chromonics. Physical investigations of the compounds were conducted by TGA, DSC, OPM, UV-Vis spectroscopy, 1H NMR and surface tension measurements. Sugar-based surfactants are interesting compounds for pharmaceutical and personal care products. Current commercially available surfactants such as alkyl poly glucoside surfactants (APGs) are prepared from low miscibility of sugars and fatty alcohols. In order to solve the miscibility problems of the starting materials, homogenizers are required. This, however, leads to impurities in products, which affects the …

Transportation sector has a dominant role in global fuel consumption and greenhouse gas emissions. Due to the dramatic increase in greenhouse gas emission, sustainable development of this sector has raised the concern in many countries including Malaysia. Biodiesel is a renewable energy that has great potential to serve as an alternative fuel to fossil diesel in the compression ignition (CI) engine. Although Malaysia is one of the biggest biodiesel fuel producers, the commercialization of biodiesel has not been fully undertaken in a large scale. Besides the technical barriers, there are several nontechnical limiting factors, which impede the development of biodiesel. …

The phytochemical analysis was carried out using hexane, chloroform and water extraction of the leaves and stems of L. flavescens. The detection methods used were thin layer chromatography (TLC), high performance liquid chromatography (HPLC) and liquid chromatography mass spectrometry combined with mass spectrometry (LCMS/MS). The TLC of all extracts using three solvents screened for flavonoids, alkaloids, saponins, terpenoids and essential oils. The HPLC have been identified quercetin, gallic acid and tannic acid using authentic standards. The HPLC chromatograms were poorly separated and not very convincing to confirm the three compounds. However the liquid chromatography mass spectrometry combined with mass spectrometry …

Diagnosis of ovarian carcinoma is in urgent need for new complementary biomarkers for early stage detection. In order to find an alternative procedure to replace an uncomfortable conventional method in detecting cervical cancer, a proteomic approach in screening the urinary proteins were employed. Proteins that are aberrantly excreted in the urine of cancer patients are excellent biomarker candidates for development of new non-invasive protocol for early diagnosis and screening purposes. In the present study, urine samples from patients with ovarian carcinoma and cervical cancer were analysed by two-dimensional gel electrophoresis (2-DE) and the profiles generated were compared to those similarly …

Granules offer advantages as an intermediate for compression of tablets. Granules can be formed by one of the technique using the fluid bed spray granulator or the spray granulation method. This technique reduces costs by combining the processes in one instrument (mixing, granulating and drying). Differential scanning calorimeter (DSC) was used as a screening technique for assessing the compatibility of paracetamol with kappa-carrageenan which is used as binder. The influence of processing effects by simple drug-excipient blending at different w: w ratio (1:1, 2;1 and 4:1) and granulation was evaluated. The results of the DSC screening show that paracetamol is …

Candida is a genus of opportunistic yeast that are usually harmless residents of the oral cavity, but they become pathogenic under conditions which allow them to increase their proportion to other members of the oral microflora. Correct and accurate identification of the candidal species infecting an oral candidiasis patient is important due to antifungal drug resistences. The region in the fungal genome that contains the gene that codes for rRNA, also known as rDNA, has been found to be useful for phylogenetic studies and species identification. The purpose of this study is to compare the candidal loads of denture wearers, …

In this work, size-control of the gold nanoparticles (Au NPs) on silicon suboxide (SiOx) film grown by vapor deposition techniques was studied. Investigation of the effects of surrounding medium on the structural properties of Au NPs was studied first. RF magnetron co-sputtering technique was used to prepare “supported ON” and “embedded IN” structure of Au/SiOx films. As-prepared samples were annealed at different temperatures from 400 to 1000 oC to study the effect of annealing temperature on the growth of Au NPs. For both structures of Au/SiOx film, size and shape of Au NPs were observed to be temperature-dependent. Au NPs …

Fish fins are appendages which represent the limbs in higher vertebrates. In general, fish moves in the water by body undulation with the assistance of fins. To date, most of the studies focused on the innervations of limbs especially in mammals, such as rats, cats and monkeys. On the contrary, understanding on the innervations of the fish fin is still at its infancy as studies on the relevant field are relatively scarce. Hence, this study aimed to fill the knowledge gap, i.e. to investigate the organisation of spinal motor neurons in relation to the distribution of the median fins. For …
