Contribution of Information and Communication Technology (ICT) in Country’S H-Index
No full textThe aim of this study is to examine the effect of Information and Communication Technology (ICT) development on country’s scientific ranking as measured by H-index. Moreover, this study applies ICT development sub-indices including ICT Use, ICT Access and ICT skill to find the distinct effect of these sub-indices on country’s H-index. To this purpose, required data for the panel of 14 Middle East countries over the period 1995 to 2009 is collected. Findings of the current study show that ICT development increases the H-index of the sample countries. The results also indicate that ICT Use and ICT Skill sub-indices positively contribute to higher H-index but the effect of ICT access on country’s H-index is not clear
Kyai dan Jawara Banten: Keislaman, Kepemimpinan dan Magic
No full textThis article tries to describe kiyai’s and jawara’s leadership inBanten. Kiyai and jawara are prominent figures, who become a symbol ofidentity of Banten, which is well known a religious region and a “countryof ‘ulamā’ and jawara.” The role and position of kiyai and jawara areimportant since the era of Kasultanan Banten until nowadays. Kiyai, withhis religious knowledge and magic competence (acquired from religoussources), serves people as an informal leader. While jawara, because of hiscourage and magic competence (obtained from kiyai), becomes a secondinformal leader after kiyai
Assessment of Models for Near Wall Behavior and Swirling Flows in Nuclear Reactor Sub-system Simulations
No full textAccurate simulation of turbulence remains one of the most challenging problems in nuclear reactor analysis and design. Due to limitations in computing resources, Reynolds averaged Navier Stokes models (RANS) continue to play an important role in reactor simulations. The Consortium for advanced simulations of light water reactors (CASL) is a Department of Energy technology hub that is investing in research and developmentof a state-of-the-art computational fluid dynamics capabilityto meet the challenges of turbulent simulation of nuclear reactors. In this presentation, we assess several RANS eddy viscosity models appropriate for single-phase incompressible turbulent flows. Specifically, we compare the single equation Splalart-Allmaras to several variations of the model. The assessment takes into consideration elements of full system reactor cores such as complex geometries, heterogeneous meshes, swirling flow, near wall flow behavior, heat transfer and robustness issues. The goal of this strategically oriented assessment is to provide an accurate and robust turbulent simulation capability for the CASL community. Metrics of performance will be constructed by comparing different models on a strategically chosen set of problems that represent reactor core sub-systems

Characterisation of supplementary fuels for co-combustion with pulverised coal
No full textThe current and future energy policy aims at increasing the share of renewable energy in worlds energy supply. One possibility to enhance energy production by renewable sources within a short term is co-combustion. This means co-firing biomass and waste with fossil fuels at existing power plants originally designed to fire fossil fuels. In Central Europe, the main interest lies in co-firing biomass and waste at pulverised coal boilers, because these plants form the basis of the currently utilised thermal fuel conversion techniques. Co-combusting supplementary fuels with coal is an economical option to increase the share of renewable energy because usually no large investments are required before implementation at large-scale utilities. Moreover, in many countries fiscal advantages are granted for renewable fuels. Co-firing can contribute to the increasing waste disposal problem by offering alternatives to landfills and waste incineration plants. When striving after higher renewable fuel shares, supplementary fuel replacement ratios at power plants increase and various problems can arise due to the differences between coal and the secondary fuels. Technical barriers that must be studied and overcome include matters related to fuel supply, fuel handling, changed combustion conditions in the boiler, ash quality and emissions. For this, the fundamental combustion properties of supplementary fuels compared with those of coal must be carefully studied. In order to better understand and predict the (co-)combustion behaviour of different biomass and waste fuels, a combination of experimental work and modelling should be used. Therefore, in the first part of this dissertation, pyrolysis of supplementary fuels is experimentally investigated by laboratory scale set-ups i.e. thermogravimetric analyser and heated wire mesh. The second part of the thesis concentrates on Computational Fluid Dynamics (CFD) modelling of co-combustion in a bench-scale, electrically heated pulverised fuel combustion reactor. Combustion sub-models are validated against experimentally determined concentration profiles and particle burnout data. The CFD model is then applied to optimise co-firing regarding supplementary fuel type, share and particle size.Design, Engineering and Productio
