Αυτοκίνητα και αξεσουάρ αυτοκινήτων: Τα γκατζετάκια που εξατομικεύουν την πολυτέλεια… (Πώς να... #123)
by Όουεν ΤζόουνςΑυτοκίνητα και αξεσουάρ αυτοκινήτων Τα γκατζετάκια που εξατομικεύουν την πολυτέλεια… Υπάρχουν πολλά είδη αυτοκινήτων. Υπάρχουν τα «οικογενειακά» που διευκολύνουν τις καθημερινότητές μας· υπάρχουν αυτά για τις βαριές εργασίες, τα βανάκια, οι νταλίκες και τα φορτηγά, και τα ονειρικά αυτοκίνητα… Ωστόσο, έχει καταφτάσει μια νέα κατηγορία: τα υβριδικά. Η γέννηση των σύγχρονων υβριδικών οχημάτων με τους δύο κινητήρες τους έλαβε μια αμφίβολη πρώτη ακρόαση από την αυτοκινητοβιομηχανία και το κοινό. Το κόστος ήταν απίστευτο και το βάρος των δύο κινητήρων σε ένα όχημα ακουγόταν ανέφικτο. Όλοι ξέρουμε πως εξελίχθηκε αυτό, αλλά ξέρεις πόσο καιρό η ανθρωπότητα πράγματι χρησιμοποιεί υβριδικά;

Solid-Liquid Separation in the Mining Industry
by Fernando Concha A.This book covers virtually all of the engineering science and technological aspects of separating water from particulate solids in the mining industry. It starts with an introduction to the field of mineral processing and the importance of water in mineral concentrators. The consumption of water in the various stages of concentration is discussed, as is the necessity of recovering the majority of that water for recycling. The book presents the fundamentals under which processes of solid-liquid separation are studied, approaching mixtures of discrete finely divided solid particles in water as a basis for dealing with sedimentation in particulate systems. Suspensions, treated as continuous media, provide the basis of sedimentation, flows through porous media and filtration. The book also considers particle aggregations, and thickening is analyzed in depth. Lastly, two chapters cover the fundamentals and application of rheology and the transport of suspensions. This work is suitable for researchers and professionals in laboratories and plants, and can also serve as additional reading for graduate courses on solid liquid separation as well as for advanced undergraduate and graduate level students for courses of fluid mechanics, solid-liquid separation, thickening, filtration and transport of suspensions in tubes and channels.

Adoption of LMS in Higher Educational Institutions of the Middle East (Advances in Science, Technology & Innovation)
by Rashid A. Khan Hassan Qudrat-UllahThis book discusses the adoption of learning management systems (LMS) in higher education institutions. It presents influential predictors that may impact instructors’ behavioral intention to adopt learning management systems in the context of Arab culture, as well as a unique model of technology acceptance that draws on and combines previous technology adoption models (i.e., a modified unified theory of acceptance and use of technology model – UTAUT2). Moreover, this study extends the UTAUT2 model by including Hofstede’s (1980) cultural dimensions, and technology awareness as the moderators of the model. It also describes the explanatory technique approach used to collect quantitative data from the instructors at higher education institutions in Saudi Arabia and were analyzed with structural equation modeling using SPSS/Amos software. The findings revealed that facilitating conditions were the strongest predictor of behavioral intention to adopt an LMS, followed by performance expectancy and hedonic motivation, technology awareness, and cultural dimensions exerted a moderating influence on instructors’ behavioral intention to use LMS in their teaching. By including new constructs, this becomes the first study of its kind exploring instructors’ use of LMS in Higher Educational Institutions of Saudi Arabia and other countries of the Middle East. It offers practical insights for a broad range of researchers and professionals at higher education institutions and serves as a reference guide for designers of learning management systems (e.g., blackboard systems), policymakers, and the Ministry of Education staff.

New Paradigms in Flow Battery Modelling (Engineering Applications of Computational Methods #16)
by Akeel A. Shah Puiki Leung Qian Xu Pang-Chieh Sui Wei XingThis book provides a comprehensive review of the latest modelling developments in flow batteries, as well as some new results and insights. Flow batteries have long been considered the most flexible answer to grid scale energy storage, and modelling is a key component in their development. Recent modelling has moved beyond macroscopic methods, towards mesoscopic and smaller scales to select materials and design components. This is important for both fundamental understanding and the design of new electrode, catalyst and electrolyte materials. There has also been a recent explosion in interest in machine learning for electrochemical energy technologies. The scope of the book includes these latest developments and is focused on advanced techniques, rather than traditional modelling paradigms. The aim of this book is to introduce these concepts and methods to flow battery researcher, but the book would have a much broader appeal since these methods also employed in other battery and fuel cell systems and far beyond. The methods will be described in detail (necessary fundamental material in Appendices). The book appeals to graduate students and researchers in academia/industry working in electrochemical systems, or those working in computational chemistry/machine learning wishing to seek new application areas.
Basic Concepts in Computational Physics
by Benjamin A. Stickler Ewald SchachingerWith the development of ever more powerful computers a new branch of physics and engineering evolved over the last few decades: Computer Simulation or Computational Physics. It serves two main purposes:- Solution of complex mathematical problems such as, differential equations, minimization/optimization, or high-dimensional sums/integrals.- Direct simulation of physical processes, as for instance, molecular dynamics or Monte-Carlo simulation of physical/chemical/technical processes.Consequently, the book is divided into two main parts: Deterministic methods and stochastic methods. Based on concrete problems, the first part discusses numerical differentiation and integration, and the treatment of ordinary differential equations. This is augmented by notes on the numerics of partial differential equations. The second part discusses the generation of random numbers, summarizes the basics of stochastics which is then followed by the introduction of various Monte-Carlo (MC) methods. Specific emphasis is on MARKOV chain MC algorithms. All this is again augmented by numerous applications from physics. The final two chapters on Data Analysis and Stochastic Optimization share the two main topics as a common denominator. The book offers a number of appendices to provide the reader with more detailed information on various topics discussed in the main part. Nevertheless, the reader should be familiar with the most important concepts of statistics and probability theory albeit two appendices have been dedicated to provide a rudimentary discussion.
