Recent Advances in Energy Harvesting Technologies

Recent Advances in Energy Harvesting Technologies

Energy demand is continuously rising mainly due to population growth and rapid economic development. There are substantial worries about the environmental effects of fossil fuels in addition to the uncertainties surrounding the long-term sustainability of non-renewable energy sources. Environmental safety concerns are driving an increase in the demand for renewable energy production. Numerous efforts have been paid to harvest energy from ambient sources e. g. solar wind thermal hydro mechanical etc. This book discusses the application of artificial intelligence (AI) for energy harvesting. The implementation of metaheuristics and AL algorithms in the field of energy harvesting system will provide a quick start for the researchers and engineers who are new to this area. Energy harvesting technologies are growing very speedily hence it is necessary to summarize recent advances in energy harvesting methodology. Over the recent years a considerable amount of effort has been devoted both in industry and academia towards the performance modelling and evaluation of energy harvesting technologies. This book is the result of a collaborative effort among different researchers in the fields of energy harvesting and artificial intelligence. Technical topics discussed in the book include: Hybrid algorithms Mechanical to electrical energy conversion Swarm intelligence MPPT technologies Polymer nanocomposites | Recent Advances in Energy Harvesting Technologies

Multirate Signal Processing for Communication Systems

Multirate Signal Processing for Communication Systems

Multirate Signal processing can improve system performance and reduce costs in applications ranging from laboratory instruments cable modems wireless systems satellites Radar Sonar and consumer entertainment products. This second edition continues to offer a systematic clear and intuitive introduction to multirate signal processing for working engineers and system designers. Significant new material and fresh concepts including Green Signal Processing techniques have been introduced. The author uses extensive examples and figures to illustrate a wide range of multirate techniques from basic resampling to leading-edge cascade and multi-stage filter structures. Along the way he draws on extensive research and consulting experience to introduce processing “tricks” shown to maximize performance and efficiency. Coverage includes:• Effect of sampling and resampling in time and frequency domains• Relationships between FIR filter specifications and filter length (# of taps)• Window design and equal-ripple (Remez) design techniques• Square-Root Nyquist and Half-band Filters including new enhancements• Polyphase FIR filters: up-sampling down-sampling• Polyphase M-path analysis and synthesis channelizers and cascade pairs• Polyphase interpolators for arbitrary sample rate changes• Dyadic half-band filters quadrature mirror filters• Channel banks for multiple arbitrary bandwidths and center frequencies • Comprehensive coverage of recursive all-pass filters and channelizers non-uniform and uniform phase mixed recursive and non-recursive• Comparisons with traditional DSP designs• Extensive applications coverage throughout | Multirate Signal Processing for Communication Systems

Veins of the Desert A Review on Qanat / Falaj / Karez

Veins of the Desert A Review on Qanat / Falaj / Karez

Qanat is a gently sloping subterranean canal which taps a water-bearing zone at a higher elevation than cultivated lands. A qanat consist of a series of vertical shafts in sloping ground interconnected at the bottom by a tunnel with a gradient flatter than that of the ground. From the air this system looks like a line of anthills leading from the foothills across the desert to the greenery of an irrigated settlement. Qanat engages a variety of knowledge and its studying entails an interdisciplinary approach. In a traditional realm qanats are embraced by a socio-economic system which guarantees their sustainability. The facets of this socio-economic system operate closely together and make it possible for the qanats to remain into future. Veins of the Desert shows that digging a qanat requires a variety of sciences and technologies though at a glance qanat is just a horizontal tunnel which drains out groundwater. Qanat is a feat of technology left from our ancestors; hidden underground but its technical importance is apparent not less valuable than such surface structures as bridges castles towers etc. Qanat enjoys extended structures and sometimes its length reaches tens of kilometers. It passes through geological formations and faces different conditions and obstacles so the qanat masters' efforts to solve these problems led to the accumulation of knowledge in terms of qanat construction over time which has been handed down from generation to generation. Qanat is one of the most complicated traditional technologies which require knowledge on nature ranging from groundwater to management. This indigenous technology used to bring water efficiently from tens of kilometers away to the thirsty lands. This book also gives insight into cultural and social heritages which have crystalized around this technique. | Veins of the Desert A Review on Qanat / Falaj / Karez
