Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Extrusion technology is widely applied in various processing (e.g. plastics, foods, pharmaceutical, rubber, and other high viscous materials) because this process combines heating, shearing, mixing and shaping in one unit operation. In food industries, twin-screw extrusion processing has played important role to fulfill the market demand of convenient food products (e.g. ready-to-eat puffed cereals and low density, expanded snack food). Therefore, understanding of twin-screw extrusion is essential for further food products development. The design and optimization of the extrusion processing has been going by trial and error experimental method, which is time consuming and requires great efforts. Moreover this method does not provide insight information of the material flow history and the mixing mechanism that is useful for the extruder design and scale up. An alternative method through numerical simulation supported by the rapid development of computer technology provides the insight information (i.e. flow field, pressure field and the mixing mechanism) of the twin-screw extrusion, which has been done in this study. 112 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This dissertation contains three topics using the Bayesian paradigm for statistical inference. The first topic is related to Bayesian sample size determination with a misclassified prevalence variable when two possibly dependent diagnostic tests are used for estimation. After accounting for the dependence structure, the required sample size will be larger than that assuming independence between the tests. The second topic is also concerned with Bayesian sample size calculation with a misclassified binary response variable. Differing from the first topic, an error-free covariate is added. Simulations demonstrate that choices of prior distributions have a great impact on the resultant sample size. The last topic is about Bayesian variable selection under the multiple linear regression model. Two competing Bayesian methods are Bayesian model averaging and reversible jump MCMC. It is found that reversible jump MCMC, expected to give better models, does not seem to differ from Bayesian model averaging in examples considered. 100 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There is a situation in Turkey where there are not enough of high-skilled labours that high-technology industries need in Turkey whereas graduates of Technical Education Faculties (TEFs) complain about the unemployment situation at the same time. This revealed that there is a situation which puts a barrier into education and training in the TEFs. This study was, hence, carried out to develop a model for personalised learning on the Internet as a solution for issues in Departments of Electrical Education in Technical Education Faculties in Turkey. The findings showed that the majority of respondents believe that personalised learning on the Internet may help to solve issues in electrical education and also detected that teachers who have normal knowledge in the level of ICTs are not able to generate interactive content except Elektronisches Buch because they know only how to use a word processor. This reveals that issues in software to generate interactive materials will be very crucial in the future. This study may be an intersting source for the audience in Information Communications and Technology field or anyone who considers ICT for Higher Education in Technology. 68 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book describes the application of simulation techniques to the operational test and evaluation (OT&E) of command support systems (CSS). OT&E is essential for ensuring that systems are effective, suitable for service and meet the end users' needs. Simulation can be used in OT&E to simulate entities that cannot be obtained for real-world OT&E and to evaluate the effectiveness of systems in controlled environments. This book defines the relationships between command and control (C2), CSS, systems engineering, verification and validation, OT&E and modelling and simulation. This book describes how simulation techniques have been used to improve OT&E of CSS and how simulation models are verified, validated and accredited. This book describes how the effectiveness of an OT&E program can be measured in terms of its cost effectiveness with respect to gathering evidence to support the resolution of critical operational issues (COIs). This book describes a proposed methodology for applying simulation in OT&E of CSS to help gather data to resolve COIs when it is impractical to conduct sufficient real-world OT&E to gather sufficient data to resolve COIs. 104 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The search for novel phases in strongly correlated systems is one of the most active frontiers in contemporary condensed matter physics. In this thesis the author explores the ground state phases of correlated electrons in one-dimension, modelled by the extended Hubbard model at half-filling, focusing on the novel bond-order-wave phase at small to intermediate couplings - a previously unknown phase whose existence was conclusively established by the author and his co-workers. The second problem studied involves the Peierls transition in correlated electrons interacting with finite frequency phonons.Both these topics have direct relevance to modelling and thus gaining an understanding of the properties of real quasi one-dimensional materials. An important aspect of the thesis is the in-depth exposition of the Stochastic Series Expansion (SSE) - a quantum Monte Carlo method that has, in the recent years, evolved into one of the most powerful computational techniques to study strongly correlated systems. The author has contributed to the development of the method and as such has a unique perspective which is bound to benefit anyone planning to learn SSE. 116 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -With new processor families appearing every few years, it is increasingly harder to achieve high performance rates in sparse matrix computations. This monograph studies new methods for sparse matrix factorizations and applies them efficiently while retaining ease of use of existing solutions. The implementations are timed and analyzed using a commonly accepted set of test matrices. Contemporary processors are used for the tests. The new factorization techniques are proven to be quite competitive with state of the art software. In addition, an optimization effort is applied to an iterative algorithm that stands out for its numerical robustness. This also gives satisfactory results on the tested computing platforms in terms of performance improvement. The same set of test matrices is used to enable an easy comparison between both investigated techniques, even though they are customarily treated separately in the literature. Possible extensions of the presented work range from easily conceivable merging with existing solutions to rather more evolved schemes dependent on hard to predict progress in theoretical and algorithmic research. 84 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Over the past decade, evaluations of multimedia products have failed to yield conclusive or consistent data concerning the effectiveness of the medium in helping students achieve learning outcomes. This is due in part to the diversity of the products themselves. There are indications that a number of factors contribute to a product s success, and that these vary from case-to-case. In order to be relevant, evaluation criteria should reflect the goals and use of the specific product. This two-phased evaluation examined the effectiveness of ProjectVideo, a CD-ROM and Web-based courseware package. Responses to open-ended questions during Phase One of the evaluation formed the basis of modifications to the product. In Phase Two, pre/post-course assessment was used to measure the effect of the courseware on student s perception of their mastery of skills. The evaluation assessed user satisfaction with product quality and the navigational structure of the course materials. The product s success in providing a supportive collaborative framework was also examined by surveying student attitudes toward group interactions and satisfaction with completed projects. 84 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The original purpose of this work was to try to meet the demands posed by the new national curriculum. However, during the process the focus was shifted towards the learning process itself and school as a learning organization. At the beginning students learning in groups, students motivation and understanding of their own learning was seen as most important. But also the teachers who tried to implement problem based learning as a teaching method noticed that their way of thinking changed; they learned how to teach. This process, learning as an implication of working together as a team, became the most important part of my study. The teachers experiences of the workshops they organized for primary school teachers were especially valuable considering present and future action. The different culture of primary schools when compared to secondary schools became visible. As the primary and lower secondary schools now are combined to a comprehensive school this difference in culture must be recognized. 244 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This thesis, which utilizes both postcolonial and feminist frameworks, details the value of a widely- popularized text like Andre Dubus III s House of Sand and Fog in academic discourse. Employing mainly the works of Gayatri Chakravorty Spivak and Chandra Talpade Mohanty, the study explains how Dubus work exposes issues of internal colonization in America for both immigrants like the Iranian Behrani family in the novel and white, less recently immigrated citizens. In addition, it acknowledges the value of distinguishing between First and Third World feminisms when working with a text like House of Sand and Fog. Through exploring issues of language, identity, class, race, sex, economic opportunity, and physical space, it argues for an opening of Dubus text that acknowledges the suppression of voice endured in separate and distinct ways by both immigrant and female voices in America. Ultimately, this thesis encourages a reconsideration of a somewhat overlooked text, as far as academic discourse is concerned, and a rejuvenation of interest in Dubus' novel. 72 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the recent global age, English has become more valued in Japan as a means of international communication. However, traditional grammar translation and audio-lingual methods still remain as a major pedagogy used by the vast majority of Japanese high schools today. Additionally, very little academic literature has been produced on the effect of 'practicing' English on a university exam. Therefore, whilst using the Center Pre-Test, a highly-valid mock test of the Japanese national university exam, this book challenges the current English education of Japan. Comparative analysis was conducted between the students who regularly engage in the practical English self-study and those who do not, with a focus on five types of the self-study methods in speaking, listening, watching TV, reading and writing. Consequently, the correlation between practical self-study and the learners' English proficiency on the university exam and several positive attitudes toward English learning were observed. This book is highly recommended and beneficial especially for the researchers and professionals in the field of foreign language teaching and learning. 88 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Demands on water supplies in the arid west are continuing to grow even though most rivers are already fully appropriated. Agriculture being the largest and least valued user of this resource will continue to be targeted to fulfill these increased demands. For water supplies to be transferred efficiently from agriculture to other beneficial uses it is necessary to determine the value of water in agriculture across different regions, uses, and legal structures. This study develops a Discrete Sequential Stochastic Programming (DSSP) model to value irrigation water in five agriculturally distinct regions throughout the Platte River Basin. The expected long run value of irrigation water is found and the model is used to interpret the changes in water value due to specific water supply conditions. The results clearly indicate how the value of water in agriculture increases significantly as the water supply decreases. In addition, the results of this study indicate which regions of the Platte River Basin might be able to provide the most cost effective source of water for preserving threatened and endangered species. 64 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Outcome Mapping is a methodology for planning, monitoring and evaluation of projects promoted by the International Development Research Centre. During its ten years of existence, the Latin American Trade Network has been incorporating this methodology gradually, adapting its tools to its own features and procedures. OM provides a series of steps to the stage of planning and project definition, and data collection mechanisms and evaluation of outcomes that allow continuous monitoring and reflection. Those data collection instruments have become the main tool for Monitoring and Evaluation of the Network. Throughout that process, the instruments and steps that the proposed methodology postulates have been adapted to the possibilities and needs of LATN, positioning this regional network as a reference on the subject. This book presents the experience of application of OM in LATN and its ongoing process of adaptation. It resumes the evaluation results of the application of that methodology during the third period of LATN, from 2003 to 2008. As a result, we propose, from our experience, to consider the scope and possibilities of this methodology in research activities. 52 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As the population of the Philippines continues to grow, poverty and civil unrest is widespread on the island of Mindanao. Mindanao's poverty can be attributed largely to past migration and economic policies of the Philippines government that delayed economic growth. Furthermore, since independence was obtained from the United States in 1946, the condition of life of Mindanao's poor has worsened due to such factors as internal conflicts between government forces and secessionist movements. This paper sheds some light on the dilemma of poverty, government policies, migration and civil unrest on Mindanao, southern Philippines. 108 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Theoretical studies and empirical evidence suggest that an optimal committee consists of roughly 5-9 members, although this result may vary somewhat under specific circumstances. This paper develops a conceptual model for the case of a monetary policy committee (MPC). The main conclusions are that (i) MPC size varies according to the size of the monetary zone and overall economic stability; (ii) for large monetary zones (EMU, USA, Japan), MPC size is close to the estimated optimal level; and (iii) in several countries, MPC size is considerably misaligned. Our model is backed by econometric evidence using a 2006 survey for 85 countries, which is available on the Web for further research. 60 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Individuals that have a sustained a traumatic brain injury (TBI) often exhibit linguistic impairments, such as narrative discourse (storytelling) deficits. Speech-language pathologists (SLPs) are responsible for diagnosing and treating these deficits. Prior to treatment, the SLP conducts an evaluation, in order to identify specific areas to treat. Currently, a limited number of resources exist for eliciting and evaluating narrative discourse in adults with TBI. Traditional methods involve using picture prompts taken from standardized language tests and asking the patient to tell a story about the picture. The SLP then uses clinical judgment to evaluate the patient s narrative. This study explores the use of personal photographs as picture prompts and a standardized checklist for evaluating the elicited narrative. This study compares the quality of narratives elicited using the a traditional picture prompt and a personal photograph. Results of this study provide useful information for SLPs or any other professionals, working with individuals with TBI, including students. This study may be an additional resource for friends and family members of individuals with TBI. 68 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Forages represent the most important, cost effective feed resource in ruminant nutrition. However, the relatively low quality of forages militates against their use as the sole feed for actively growing or high-performing ruminants. Several methods have been used to improve forage quality, and therefore animal performance, by chemical or biological treatments. Fibrolytic enzyme application is one of the most studied biological treatments for improving forage quality and animal performance. Such enzymes have been effective at improving the utilization of a wide range of diets containing roughages due to improved fiber hydrolysis which often results in increased digestibility, voluntary intake and animal performance. However, results of enzyme effectiveness still been controversial. There are several factors that contribute to this controversy, and all these factors are discussed in this book, and it elucidates if these products are really effective for improving forage quality and animal performance. 116 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Pitcairn Island is a small volcanic Island in the South Central Pacific. Pitcairn famously is home to descendants of the Bounty mutineers who hid out there after seizing the ship from Captain Bligh. The flora of Pitcairn Island is of international interest due to the large ratio of endemic plant species on the island. The islanders imported a timber producing species called 'Roseapple' (Syzygium jambos) to the island in the 1800's, it has now spread to cover most of the centre of the island, outcompeting the native forest and its endemic species. This research project investigated ways of controlling Roseapple and developed propagation protocols for many of the native and endemic species, which were used to replant areas where Roseapple was treated. The local community were fully involved with the project and an economic assessment of the cost of control and restoration was carried out. Genetic fingerprints were produced of the most threatened endemic species and recommendations for their ongoing conservation are outlined. 248 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Semi-Markov processes (SMP) are powerful stochastic tools for modeling reliability measures over time. This work precisely aims at proposing more efficient mathematical and numerical treatments for SMP in continuous time. The first approach (called 2N-) is based on transition frequency densities and general quadrature methods. The other proposed method (in short Lap-) applies Laplace transforms that are inverted by a Gaussian quadrature method known as Gauss Legendre to obtain the state probabilities in time domain. Mathematical formulation of these approaches as well as descriptions of their numerical treatment are developed and provided with details. The effectiveness of the novel 2N- and Lap- developments is validated by using examples in the context of oil industries. It is shown that the 2N- and Lap- approaches are significantly less time- consuming and have comparable accuracy to Monte Carlo simulation based solution. 108 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Nowadays hi-tech secure products need more services and more security. Furthermore the corresponding market is now oriented towards more flexibility. In this thesis we propose as novel solution a Multi-algorithm Cryptographic Co-processor called Celator. Celator is able to encrypt or decrypt data blocks using private key encryption algorithms such as Advanced Encryption Standard (AES) or Data Encryption Standard (DES). Moreover Celator allows condensing data using the Secure Hash Algorithms (SHA). These algorithms are frequently implemented in hi-tech secure products in software or in hardware mode. Celator belongs to the class of the flexible hardware implementations, and allows an user implementing its own cryptographic algorithm under specific conditions. Celator architecture is based on a 4x4 Processing Elements (PE) systolic array, a Controller with a Finite State Machine (FSM) and a local memory. Data are encrypted or decrypted by the PE array. This thesis presents Celator architecture, as well as its AES, DES, and SHA basic operations. Celator performances are then given and compared to other securitycircuits. 108 pp. Englisch.…
