Quantum information is an area of science, which brings together physics, information theory, computer science & mathematics. This book, which is based on two successful lecture courses, is intended to introduce readers to the ideas behind new developments including quantum cryptography, teleportation & quantum computing.
This book describes the design, development, characterisation and application of two novel fluorescence imaging instruments based on spectrally resolved detector arrays (SRDAs). The simplest SRDA is the standard colour camera, which integrates a Bayer filter array of red, green and blue colour filters to replicate the colour sensing capability of the human eye. The SRDAs used in this book contain many more colours, ranging from 16 to over 100 colour channels. Using these compact, robust and low-cost detectors for biomedical applications opens new avenues of exploration that were not possible before, in particular, the use of spectral imaging in endoscopy. The work presented shows for the first time that not only can this new type of camera be used for fluorescence imaging, but also that it is able to resolve signals from up to 7 different dyes - a level of multiplexing not previously achieved in tissue with such compact and robust equipment. Furthermore, it reports the application of a bimodal endoscope performing both reflectance and fluorescence imaging using these cameras in an ex vivo pig oesophagus model.
This book presents a theoretical study of heat transfer due to laminar natural convection of nanofluids, using Al2O3-water nanofluid as an example. An innovative method of similarity transformation of velocity fields on laminar boundary layers is applied for the development of a mathematical governing model of natural convection with actual nanofluids, and a novel model of the nanofluid´s variable thermophysical properties is derived by a mathematical analysis based on the developed model of variable physical properties of fluids combined with the model of the nanofluid´s thermal conductivity and viscosity. Based on these, the physical property factors of nanofluids are produced, which leads to a simultaneous solution for deep investigations of hydrodynamics and heat transfer of nanofluid´s natural convection. The book also proposes novel predictive formulae for the evaluation of heat transfer of Al2O3-water nanofluid´s natural convection. The formulae have reliable theoretical and practical value because they are developed by rigorous theoretical analysis of heat transfer combined with full consideration of the effects of the temperature-dependent physical properties of nanofluids and the nanoparticle shape factor and concentration, as well as variations of fluid boundary temperatures. The conversion factors proposed help to turn the heat transfer coefficient and rate of fluid natural convection into those of nanofluid natural convection. Furthermore, several calculation examples are provided to demonstrate the heat transfer application of the proposed predictive formulae.
Your taxes are going up; your electric and gas bills are costing more; and the government is telling you to use your air conditioner less in the summer. Why? For an energy crisis that doesn´t exist. In Energy: The Created Crisis, Antony C. Sutton confirms the suspicion long held by many that the energy ´´crisis´´ is a hoax perpetrated on the American people by big government aided and abetted by big business. Topics: America´s present reserves are enough for the next 2000 years. How and why the US government works to obstruct energy development. Which huge multi-national companies are most politically active in supporting the government´s efforts to encourage the energy ´´crisis´´ and why. Nuclear energy is far cheaper and safer than oil, coal, and gas. The ruling elite, and who they are and why they´re working against you. Energy: The Created Crisis exposes the energy ´´crisis´´ plot, explains how it works, and tells how the free market can sweep it away.
