This work is focused on the thermodynamic optimization of Organic Rankine Cycles (ORCs), coupled with absorption or adsorption cooling units, for combined cooling heating and power (CCHP) generation from biomass combustion. Results were obtained by modelling with the main aim of providing optimization guidelines for the operating conditions of these types of systems, specifically the subcritica...

For the case with repetitive driving cycles for a wheel loader the driving cycles parameters affects on the optimal control of the wheel loader is studied. It is clearly seen that average efficiency is not enough and also incorporating driving cycles parameter such as average power, maximum power and amount of recuperative energy will lead to an better estimate on the fuel equivalence factor W .

Operative laparoscopy has changed the concept of surgery from prolonged painful recuperative periods with long scars of open surgery to short stay, painless, and cosmetically satisfying surgery. This has been achieved at the expense of surgeons’ discomfort and fatigue, thus putting both the surgeon and patient at risk. Inadequate knowledge about ergonomics together with ergonomically deficient ...

Laparoscopic Nissen fundoplication is the current standard surgical option for complicated GERD and symptomatic hiatal hernia. Though comparable in safety, short-term efficacy, and patient satisfaction when compared with open operation, laparoscopic Nissen fundoplication has demonstrated shorter hospital stays and recuperative times. Commonly reported complications include gastric or esophageal...

Gas-To-Liquid (GTL) processes have great potential as alternative to conventional oil and coal processing for the production of liquid fuels. In GTL-processes the partial oxidation of methane (POM) is combined with the Fischer-Tropsch reaction. An important part of the investment costs of a conventional GTL-plant is related to cryogenic air separation. These costs could be substantially reduced...

An updraft tower cooling system is assessed for elimination of water use associated with power plant heat rejection. Heat rejected from the power plant condenser is used to warm the air at the base of an updraft tower; buoyancy-driven air flows through a recuperative turbine inside the tower. The secondary loop, which couples the power plant condenser to a heat exchanger at the tower base, can ...
