in this paper, a new combined power and refrigeration cycle is proposed, which combines the rankin power cycle and the ejector refrigeration cycle. this combined cycle produces both power output and refrigeration output simultaneously. this cycle is driven by the flue gas of gas turbines, industrial waste heats, solar energy and geothermal energy. an exergy analysis is performed to guide the th...

Cardiac electrophysiological dysfunction is a major cause of death in humans. Accordingly, electrophysiological testing is routinely performed in intact, conscious, humans to evaluate arrhythmias and disorders of cardiac conduction. However, to date, in vivo electrophysiological studies in mice are limited to anesthetized open-chest or closed-chest preparations. However, cardiac electrophysiolo...

How and when eukaryotic cells make the irrevocable commitment to divide remain central questions in the cell-cycle field. Parallel studies in yeast and mammalian cells seemed to suggest analogous control mechanisms operating during the G1 phase-at Start or the restriction (R) point, respectively-to integrate nutritional and developmental signals and decide between distinct cell fates: cell-cycl...

Most of gait recognition algorithms involve walking cycle estimation to accomplish signature matching. However, we may be plagued by two cycle-related issues when developing real-time gait-based walker recognition systems. One is accurate cycle evaluation, which is computation intensive, and the other is the inconvenient acquisition of long continuous sequences of gait patterns, which are essen...

A novel, patented topping power cycle is described that takes its energy from a very high-temperature heat source and in which the temperature of the heat sink is still high enough to operate another, conventional power cycle. The top temperature heat source is used to evaporate a low saturation pressure liquid, which serves as the driving fluid for compressing the secondary fluid in an ejector...

Transport of ore and overburden in open-pit mines is often performed with large haul trucks. Battery-electric operation trucks can significantly reduce the CO2 emissions fossil fuel dependence mining. This simulation study investigates feasibility economy operating battery-electrically, charging from an electric road system form overhead trolley lines. The used model verified against measuremen...

A 1D electrochemical-thermal model is developed to characterise the behaviour of a 53 Ah large format pouch cell with LiNixMnyCo1-x-yO2 (NMC) chemistry over a wide range of operating conditions, including: continuous charge (0.5C-2C), continuous discharge (0.5C-5C) and operation of the battery within an electric vehicle (EV) over an urban drive-cycle (WLTP Class 3) and for a high performance EV...

Scheduling any complicated job shop becomes increasingly more difficult when the cycle time is reduced. This paper will discuss the implementation of a simulationbased scheduling system that properly schedules parts in a two-plant operation. The system has allowed the company to reduce the cycle time by at least a week from two/three weeks to one/two weeks. As part of the project, the generatio...

The most well-known biological theory is that women feel their sex drive kick into highest gear during ovulation at mid-cycle, approximately 14 days before they get their next period. The surge in estrogen and the added testosterone bonus that accompany ovulation explain why some women experience heightened libido during this time. This change makes logical sense when viewed within the context ...
