Combined heat and power (CHP) production is an increasingly important energy production technology. CHP production is usually applied in back pressure plants, where the heat and power generation follows a joint characteristic. A CHP system may also comprise separate heat and power production facilities. Cost-efficient operation of a CHP system can be planned using an optimisation model based on...

this study evaluated 2 elt textbooks (four corners, book 2 and four cornersbook 3) drawing on bloom’s revised taxonomy (brt); it examined the extent towhich these elt textbooks could demonstrate the 6 cognitive categories of the brt(i.e., remembering, understanding, applying, analyzing, evaluating, and creating) intheir activities. to this end, content analysis was done to obtain the frequency ...

We first introduce matrix concepts in linear programming by developing a variation of the simplex method called the revised simplex method. This algorithm, which has become the basis of all commercial computer codes for linear programming, simply recognizes that much of the information calculated by the simplex method at each iteration, as described in Chapter 2, is not needed. Thus, efficienci...
