Abstract:

Cricket balls behave differently at various stages of the game depending upon how much wear and tear has taken place due to use. The playing performance of cricket balls depends largely on the surface texture. The ball is swung using the primary seam during the early stages of the game but later the surface roughness starts to affect the lateral movement. This work attempts to find a quantitative measure of the surface roughness of cricket balls and then uses it to discriminate between new and old balls. Area-scale fractal analysis is used to find the surface roughness in order discriminate be

Abstract:

Summary The development of urbanization and industrialization has improved the comfort level and the quality of human’s life effectively. But at the same time, it also caused many global environment problems, such as air pollution, greenhouse effect and urban heat island (UHI). The environment cannot keep the balance because of lots of industrial activities, anthropogenic heat and building surface effect. Almost 3 billion people, who are living in cities, have to face this situation, and the quantity is still increasing. The authors use literature research methodology, case study, comparative

The tool couldn’t analyze images of carbon nanotube networks if theimages were to noisy or the networks to dense.

Thus, the primary aim of the research was to develop a sorbent material that facilitates rapid clean-up of road spills.

Abstract:

O Vírus da Imunodeficiência Humana (HIV) é o agente etiológico da Síndrome da Imunodeficiência Adquirida (AIDS). A AIDS é uma doença de distribuição mundial, e estima-se que existam atualmente pelo menos 36,9 milhões de pessoas infectadas com o vírus. Durante o seu ciclo replicativo, o HIV promove diversas alterações na fisiologia da célula hospedeira a fim de promover sua sobrevivência e potencializar a replicação. A rápida progressão da infecção pelo HIV-1 em humanos e em modelos animais está intimamente ligada à função da proteína acessória Nef. Dentre as diversas ações de Nef está a regula

However, the lack of comfort and the reduction of dexterity of hands often frustrate the use of gloves. Thus, a good design of gloves has to provide both fitness and movability for hands. For fitness, traditionally hand dimensions had been measured by tapes, calipers and Martin-type anthropolometers to develop glove size models. Or nowadays the surface shape of hands had been measured by 3D laser scanning technologies under some standard posture to estimate the shape and area o

碩士<br>國立成功大學<br>航空太空工程學系<br>106<br>The major combustible components from gasification of biomass are hydrogen (H2), carbon monoxide (CO) and methane (CH4). In order to fully utilize the gasified products, an understanding of the combustion characteristics of the product mixtures is crucial. Laminar flame speed is one of the important properties to characterize fuel gas burning for combustion chamber design as well as in the simulation of turbulent flame propagation. This thesis research focuses on the combustion of the mixtures of CH4 CO. By using a self-designed tube method, the flame propaga

Abstract:

碩士<br>國立高雄海洋科技大學<br>海洋環境工程研究所<br>95<br>For long, it has been hypothesized in the ozone air quality model that volatile organic compounds (VOCs) in the atmosphere are evenly mixed at all heights. However, in recent years, scientists have begun to doubt about the reasonability of this hypothesis, and a number of studies have pointed out the existence of VOC stratification and the need for more academic attention. The research of VOC in the air is usually subject to the difficulty in sampling, low background cleanness, difficulty in acquiring sampling facilities, complicated research procedures,

Abstract:

In 1968, Rein Taagepera created growth curves of four empires by measuring the surface area of each and plotting his data on a graph of area versus time. He used his growth curves to analyse the development of empires quantitatively, as he considered surface area to be the best measurable indicator of an empire’s strength. His growth curve of the Roman Empire, in particular, has been referenced numerous times by scholars researching the decline and fall of complex civilizations to support their individual analyses of the collapse of Rome. While this thesis surveys only the territories of the W

碩士<br>國立高雄應用科技大學<br>模具工程系<br>97<br>The paper aims to apply the thermodynamics second law to investigate the laminar film condensation heat transfer from the vapor flowing slowly onto various vertical ellipsoids under constant surface area, including under variable wall temperatures. The numerical approach to the entropy generation, based on Adrian Bejan`s entropy generation minimization, is conducted in terms of Brinkman; Jakob, and Rayleigh parameters . The result indicates that the total entropy generation rate is proportional to the ellipticity of the vertical ellipsoid under constant surfa

Abstract:

Maritime Unmanned Vehicles are tools being developed to explore oceans, rivers, lakes and reservoirs. These tools are essential to completely understand the unknown maritime world, since they have relatively low operation costs and can perform several multipurpose investigations. These main applications can be divided in different operations types like oceanographic and atmosphere measurements. One type of these tools are called Autonomous Surface Vehicles (ASV), which, as the name implies, are autonomous vessels that operate at water’s surface. In this dissertation, different types of geometr
