Because of their extremely fine grain size, nanocrystalline (<100 nm) materials exhibit novel combinations of physical, mechanical, and magnetic properties. Titanium-based nanostructured materials-both terminal alloys and intermetallic compounds-show the potential for enhanced behavior aver material with more conventional grain sizes (>1 11m).

Abstract:In this study, the current situation of the General Electric Company of Libya (GECOL) was assessed by measuring the total and partial service productivity from 2006 to 2014, using a proposed measurement model, which was constructed based on a well-known model adopted for analysis of productivity which satisfies the basic productivity concept. Two phases were used in this study to measure the company's productivity. In phase one, productivity was measured using the outputs data based on the electricity delivered (excluding) the technical losses in order to obtain the accurate productivity of the company. In phase two; an attempt was made to find the actual output, by using the electricity delivered including the technical losses to obtain the productivity that represents the true performance. The results showed that there was a decline in the productivity of the company in all years of the study period and that the company's overall performance during the study period was generally poor.
