Conventional air-conditioning (AC) systems produce considerable amount of cold condensate as moist air is cooled below the dew point. The condensate is commonly drained resulting in thermal loss. The waste thermal energy can be recovered to increase the overall coefficient of performance (COP) by ci.....

Environmental pollution induced by the accumulation of plastic wastes, also known as “white pollution” has becoming increasingly serious during recent years. Therefore the development of degradable materials to replace or decrease the usage of non-degradable plastics is of great importance from both.....

It was found that when conventional cancer therapeutic drugs have been used for an extended period of time for treating cancer, some cancer cells will become multi-drug resistant (MDR). This is undesirable as relapses would occur, and the treatment of relapses will become more difficult. The present.....

Biomolecular interactions are essential for drug design and computer-aided methods are commonly used to simulate/predict such interactions to save time and cost. Two alpha shapes, instead of one, are used to construct the interface surface of two biomolecules. A fully automated algorithm is devised .....

The invention proposes the adding ay to the insidof a small time-dele differential link of a PID controller. The differential action efficiency is satisfactory when the time delay is little. In case the time delay is large, the differential action work will switch to the proportional control operati.....
