Chopper Based Speed Control Of D.C. Motor
39,90 € *
ggf. zzgl. Versand

In Power & Process Industry, there is growing demand for automated system to control speed of D.C. Motors. As the close loop system for speed control of D.C. Motor which incorporate software & hardware is advantageous in comparison to open loop system of speed control which incorporate only hardware. And chopper based system having MOSFET as switching device with higher rate of ON/OFF frequency is popular among Power Electronics Engineers to design the circuitry with less components.

Road Speed Limit Enforcement in the United Kingdom
40,10 € *
ggf. zzgl. Versand

High Quality Content by WIKIPEDIA articles! Road speed limit enforcement in the United Kingdom is the action taken by appropriately empowered authorities to check that road vehicles are complying with the UK speed limit in force on roads and highways. Methods used include roadside speed traps set up and operated by the police and automated roadside speed camera systems which may incorporate the use of an automatic number plate recognition system. Traditionally the police would have used stopwatches to measure the time taken for a vehicle to cover a known distance, but latterly they have speed guns and automated in-vehicle systems at their disposal.

Lexical Facility
97,98 € *
ggf. zzgl. Versand

This book examines the simultaneous contribution of learner vocabulary size and speed to second language performance differences across learner levels and settings. Harrington considers vocabulary size and speed, as reflected in retrieval speed and consistency, as a three-dimensional measurement construct termed lexical facility. While size and retrieval speed are generally known, this is the first attempt to incorporate consistency, as measured by the coefficient of variation, as an index of vocabulary skill. Part 1 describes the three dimensions and the roles they play on lower level text processing and thus on second language performance more generally. Part 2 reports on seven studies and related research that investigate the sensitivity of the three dimensions, both individually and in combination, to proficiency differences in common domains of academic English performance. Harrington's framework and the theoretical and methodological issues that arise are presented in a manner accessible to a wide readership, including second language acquisition vocabulary researchers, testing and assessment practitioners, and those interested in second language research methodology.

Measuring Technology Maturity
78,29 € *
ggf. zzgl. Versand

Till Albert presents amachine learning based approach to harnessing information contained in big datafrom different media sources such as patents, scientific publications, or theinternet. He shows how this information can be used for automated maturityevaluation of yet unknown technologies. Elaborate patent based indicators containvery useful information on technological aspects of maturity but lack forothers such as social, economic, ecological, or political factors. The approachpresented in this book is able to incorporate these other factors and provide afirm basis for robust technology maturity and speed of maturity evaluation.

Marconi's Wireless and the Rhetoric of a New Te...
47,92 € *
ggf. zzgl. Versand

This book examines the discourse surrounding the wireless, created by the Anglo-Italian inventor Guglielmo Marconi. The wireless excited early twentieth-century audiences before it even became a viable black box technology. The wireless adhered to modernist values-speed, efficiency, militarization, and progress. Language surrounding the wireless is a form of technical communication, overlooked by today's practitioners. This book establishes a broader definition for technical communication by examining a selection of the discourse surrounding Marconi's wireless. The book's main themes are the following: 1) technical communication is all discourse surrounding technology, 2) the field of technical communication (or technical writing) should incorporate analyses of discourse surrounding technologies into its epistemology, 3) the wireless is a product of the society from which it comes (early twentieth-century Western civilization), and 4) the discourse surrounding the wireless is infused with tropes of progress-speed, efficiency, evolution, and ahistoricity.

Artificially Controllable Nanodevices Construct...
112,92 € *
ggf. zzgl. Versand

In this book, the author deals mainly with two topics: (1) single-molecule visualization of switching behaviors in the DNA nanoframe system utilizing different kinds of molecular switches through the use of high-speed atomic force microscope (AFM), (2) construction of photocontrollable DNA nanostructures in programmed patterns and direct visualization of the dynamic assembling process. Here, high-speed AFM was employed to observe the dynamic movements of single molecules. Compared to a traditional single-molecule analysis method, such as fluorescence spectroscopy or electron microscopy, high-speed AFM makes possible the real-time observation of molecule behaviors. DNA nanostructures were designed and assembled as scaffolds to incorporate interested biomolecules. The observations were carried out under robust conditions without complicated pretreatment. Moreover, the photoresponsive molecules were successfully assembled into around 100 nm-sized DNA nanostructures. The assembly/disassembly of nanostructures can be regulated reversibly by photoirradiation. This book explains how DNA origami has gradually become a useful tool for the investigation of biochemical interactions in defined nanospace. It also shows the possibility of DNA nanostructures acting as nanodevices for application in biological systems, serving as a good introduction to basic DNA nanotechnology.
