Abstract Fuel cell technology one of the hottest topics in the green energy industry and has become a popular topic in most of the international green energy symposiums. In the meantime,the development of the fuel cell industry has been recognized as one of the key rising industries in Taiwan. Since 2009,the Industrial Technology Research Institute(ITRI) has collaborated with Chung-Hua Institution for Economic Research(CIER) for implementing the fuel cell demonstration and promotion programs which are supported by the Bureau of Energy, Ministry of Economic Affairs. This program focuses on three major areas for application of fuel cells:backup power supply,ordinary power supply, and… More >

Abstract In any ancient society whose economy is mainly driven by agriculture, the production of foods, such as wheat, potato and rice is an essential factor in defining its economics as well as demographics. We are now trying to simulate the demographics and economics of the Japanese ancient agricultural society during 0-1850 A.D., from the primitive era (Yayoi) to the last part of Edo era, when the general was still governing this country. At that time, the society depended heavily on the rice production along river areas. The multi-agent and cell automaton simulation is performed over Japanese islands, and the distribution… More >

Abstract Artificial intelligence has opened a new window of opportunity and has definitely a long way to look ahead in\nobreakspace {}area of data analysis. The enormity of magnitude of data and its complex nature often perplex the epidemiologists. This is especially true in case of vector borne diseases where a timely and precise understanding of disease during decision making process comes handy for curbing the diseases in event of an outbreak or epidemic. Often the public health officials feel the need of correct identification of true positive cases. A tool that classify disease according to presence or absence of a disease… More >

Abstract Intensive heat and mass transfer between continuum fluids and discrete particulate materials plays a critical role in many chemical reactors [1]. For example, the shaft furnace and the blast furnace in ironmaking are operated with continuous charge and discharge of solid materials, and it takes hours for the solid materials moving from the furnace top to the bottom. To understand and improve the operation of these reactors, discrete particle models are very helpful when combined with flow, heat and mass transfer, and chemical reaction models [2-6]. However, due to the high computational cost with such discrete particle models, it is… More >

Abstract First-year ice ridges determine the design load of moored structures in many Arctic and sub-Arctic regions. Their interactions with moored structures were simulated with discrete element method (DEM), considering the complex internal structures of ice ridges. In the simulation, ice ridges were modeled as an assembly of consolidated ice blocks randomly packed through a dynamic process. The shapes of ice blocks were generated based on Voronoi tessellation and then filled with bonded sphere elements. The model was calibrated and validated by comparing the numerical results with the punch through experiments and direct shear box experiments data in the literature. Based… More >

Abstract An important issue for MIZ (Marginal Ice Zone) simulation is the correct prediction of ice-wave interaction. The energy of wave will be eliminated and at the same time induces the breakage and fragment of level ice. To study ice failure and the floe-size distribution (FSD) after fracture will help to improve the accuracy of further numerical simulation. We present a three-dimensional DPDEM (Dilated Polyhedral Discrete Element Method) in which element is similar to the real shape of single block to simulate the ice fracture process under the wave load. A large number of polyhedral ice elements generated with Voronoi tessellation… More >

Abstract Granular flow is commonly encountered in industry or nature, and is significantly affected by particle shapes. Super-quadric particles which can construct the geometric shape of irregular particles are simulated by the Discrete Element Method (DEM). In this study, the influence of aspect ratio and blockiness of particles on the flow characteristics is investigated, and the different discharge angles are used for different shaped particles to show the superposed effect of hopper configuration. Meanwhile, the Lacey mixing index is used to explore the effects of particle shapes on the mixing and motion of the granular system in a horizontal rotating drum.… More >

Abstract The inorganic components of crustacean shells are usually removed using HCl solutions. This provokes undesirable modifications in the extracted chitin. In the present procedure, deproteinized lobster shells were demineralized with CO2 and a cationic resin (cationite). The resulting chitin (CHI-CO2) is compared in terms of degree of acetylation (DA), crystallinity index (CrI) and thermal stability with chitins obtained by demineralization procedures with HCl (CHI-HCl) and ethylenediaminetetraacetic acid (CHI-EDTA). The ash content of chitins demineralized with CO2 was similar to that of chitins prepared using HCl or EDTA. However, the resultant DA and CrI of CHI-HCl and CHI-EDTA were lower than… More >

Abstract Text visualization is concerned with the representation of text in a graphical form to facilitate comprehension of large textual data. Its aim is to improve the ability to understand and utilize the wealth of text-based information available. An essential task in any scientific research is the study and review of previous works in the specified domain, a process that is referred to as the literature survey process. This process involves the identification of prior work and evaluating its relevance to the research question. With the enormous number of published studies available online in digital form, this becomes a cumbersome task… More >

Abstract A numerical large eddy simulation (LES) method combined with the characteristic-based operator-splitting finite element method is proposed. The subgrid eddy viscosity model is used to calculate sub-grid stress in LES. In each time step, the governing equations are split into diffusive and convective parts. The convective part is first discretized by using the characteristic Galerkin method and then solved explicitly. The backward-facing step flow and the flow past a single cylinder are adopted to validate the model. Results agree with existing numerical results or experimental data. The flow past two cylinders in tandem arrangement is also studied at Re =… More >
