Free Download Optimizing Online English Language Learning and Teaching (English Language Education, 31) by Maria-del-Mar Suárez, Walaa M. El-Henawy English | April 15, 2023 | ISBN: 3031278240 | 396 pages | MOBI | 9.72 Mb This book focuses on English as a Foreign Language (EFL) and provides advice on how to approach EFL teaching in the online context. Coronavirus has accelerated e-learning significantly and has highlighted the need of appropriate web tools that will allow teachers to present their material either synchronously or asynchronously, while also adequately assess their students. At the same time, there is a need of tools that can engage the students and motivate them to actively participate in the lesson.  Free Download Optimizing HPC Applications with Intel Cluster Tools: Hunting Petaflops by Alexander Supalov , Andrey Semin , Michael Klemm , Christopher Dahnken English | PDF EPUB (Both True) | 2014 | 291 Pages | ISBN : 1430264969 | 12 MB Optimizing HPC Applications with Intel® Cluster Tools takes the reader on a tour of the fast-growing area of high performance computing and the optimization of hybrid programs. These programs typically combine distributed memory and shared memory programming models and use the Message Passing Interface (MPI) and OpenMP for multi-threading to achieve the ultimate goal of high performance at low power consumption on enterprise-class workstations and compute clusters.  Free Download Optical Hall Effect in the Sharp Focus of Laser Light by Victor V. Kotlyar, Alexey A. Kovalev, Anton G. Nalimov English | September 15, 2024 | ISBN: 3031646827 | 295 pages | MOBI | 44 Mb This book explores the optical Hall effect in the sharp focus of laser light. It builds upon the established theory of Richards-Wolf (1959), providing numerous real-world examples that illustrate both spin and orbital Hall effects near the focal point.  Free Download Optical Fiber Sensor Technology: Chemical and Environmental Sensing by K. T. V. Grattan, B. T. Meggitt English | PDF | 1999 | 340 Pages | ISBN : 0412844206 | 36.7 MB Environmental and chemical sensors in optical fiber sensor technology The nature of the environment in which we live and work, and the precarious state of many aspects of the natural environment, has been a major lesson for scientists over the last few decades. Public awareness of the issues involved is high, and often coupled with a scepticism of the ability of the scientist and engineer to provide an adequate, or even rapid solution to the preservation of the environment before further damage is done, and to achieve this with a mini mum of expenditure. Monitoring of the various aspects of the environment, whether it be external or internal to ourselves and involving chemical, physical or biomedical parameters is an essential process for the well-being of mankind and of the individual. Legis lative requirements set new standards for measurement and control all around us, which must be met by the most appropriate of the technologies available, commensurate with the costs involved. Optical fiber sensor technology has a major part to play in this process, both to complement existing technologies and to promote new solutions to difficult measurement issues. The developments in new sources and detectors covering wider ranges of the electromagnetic spectrum, with higher sensitivity, allow the use of techniques that some time ago would have been considered inappropriate or lacking in sufficient sensitivity.  Free Download Optical Fiber Sensor Technology: Applications and Systems by K. T. V. Grattan, B. T. Meggitt English | PDF | 1999 | 330 Pages | ISBN : 0412825708 | 29.8 MB Systems and Applications in Optical Fiber Sensor Technology The essential technology which underpins developments in optical fiber sensors continues to expand, and continues to be driven to a very large extent by advances in optoelectronics which have been produced for the ever-expanding optical com munications systems and networks of the world. The steps forward in the technol ogy, often accompanied by a reduction in the price of associated components, have been, and continue to be, adapted for use in a wide variety of optical fiber sensor systems. These include, for example, the use of photoinduced gratings as fiber sensor components, coupled with the wider availability of shorter wavelength lasers, bright luminescent sources and high-sensitivity detectors which have opened up new possibilities for both novel fiber optic sensor applications and new sensing systems. This is to be welcomed at a time when, coupled with integrated optic miniaturized devices and detectors, real possibilities of systems integration, at lower cost and increased utility, can be offered. The fiber laser, and the expansions of the types and availability of the doped fiber on which it is based, offer further examples of the integration of the essential components of advanced optical sensor systems, fitted for a new range of applications. |
