TL;DR: In this paper, an experimental single stage heat transformer (SSHT) with water/carrol mixture was analyzed. But the performance of the SSHT was not evaluated. But four test runs were carried out in order to evaluate the performance and the heat powers were measured from 0.99 to 1.35.

Abstract: A review of the performance and development of absorption heat transformers is presented. The review covers the current state of theoretical and experimental studies of single and advanced systems, operating with conventional or alternative mixtures. It also includes their applications, such as waste heat recovery from industrial processes, cogeneration systems and seawater desalination and distillation among others. A bibliographic review has been done based on international journals, dating back from 1986 to date. The review does not intend to be exhaustive, but to reflect the most important research that has been published concerning these technologies

TL;DR: In this article, a magnetophoretically formed high aspect ratio nano-nodes are used for hot-spot cooling in microfluidic environments, which can be dynamically chained and docked onto the hot spots to establish tuneable high-aspect ratio nanofins for the heat exchange between these hot spots and the liquid coolant.
Abstract: The limitation of hot spot cooling in microchips represents an important hurdle for the electronics industry to overcome with coolers yet to exceed the efficiencies required. Nanotechnology-enabled heat sinks that can be magnetophoretically formed onto the hot spots within a microfluidic environment are presented. CrO2 nanoparticles, which are dynamically chained and docked onto the hot spots, establish tuneable high-aspect-ratio nanofins for the heat exchange between these hot spots and the liquid coolant. These nanofins can also be grown and released on demand, absorbing and releasing the heat from the hot spots into the microfluidic system. It is shown that both high aspect ratio and flexibility of the fins have a dramatic effect on increasing the heat sinking efficiency. The system has the potential to offer a practical cooling solution for future electronics.

TL;DR: This survey presented a comprehensive investigation of PSO, including its modifications, extensions, and applications to the following eight fields: electrical and electronic engineering, automation control systems, communication theory, operations research, mechanical engineering, fuel and energy, medicine, chemistry, and biology.
Abstract: Particle swarm optimization (PSO) is a heuristic global optimization method, proposed originally by Kennedy and Eberhart in 1995. It is now one of the most commonly used optimization techniques. This survey presented a comprehensive investigation of PSO. On one hand, we provided advances with PSO, including its modifications (including quantum-behaved PSO, bare-bones PSO, chaotic PSO, and fuzzy PSO), population topology (as fully connected, von Neumann, ring, star, random, etc.), hybridization (with genetic algorithm, simulated annealing, Tabu search, artificial immune system, ant colony algorithm, artificial bee colony, differential evolution, harmonic search, and biogeography-based optimization), extensions (to multiobjective, constrained, discrete, and binary optimization), theoretical analysis (parameter selection and tuning, and convergence analysis), and parallel implementation (in multicore, multiprocessor, GPU, and cloud computing forms). On the other hand, we offered a survey on applications of PSO to the following eight fields: electrical and electronic engineering, automation control systems, communication theory, operations research, mechanical engineering, fuel and energy, medicine, chemistry, and biology. It is hoped that this survey would be beneficial for the researchers studying PSO algorithms.

TL;DR: In this article, a state-of-the-art review is presented of the different technologies that are available to deliver refrigeration from solar energy, including solar electric, solar thermal and some new emerging technologies.
Abstract: A state-of-the-art review is presented of the different technologies that are available to deliver refrigeration from solar energy. The review covers solar electric, solar thermal and some new emerging technologies. The solar thermal systems include thermo-mechanical, absorption, adsorption and desiccant solutions. A comparison is made between the different solutions both from the point of view of energy efficiency and economic feasibility. Solar electric and thermo-mechanical systems appear to be more expensive than thermal sorption systems. Absorption and adsorption are comparable in terms of performance but adsorption chillers are more expensive and bulkier than absorption chillers. The total cost of a single-effect LiBr–water absorption system is estimated to be the lowest.
