P/EN/30. Multiple design parameters and the yield stress

The paper examines the relationship between the room temperature yield pressure of InxGa1-xAs superlattices measured by nanoindentation and the volume averaged strain modulation. The dependence of the yield stress on multiple design parameters is studied indicating the simultaneous onset of plastic deformation across a finite volume. Conclusions are made about the relationship which exists with yield decreasing in response to increased strain modulation.

S/EN/15. Solid waste incineration and its associated pollutants within the US

In the US the use of incineration technology continued to rise until the late 1980s, however the bubble burst in the early 1990s as incineration was declared very harmful to the environment. Nowadays incineration continues within the US as new, more efficient units replace law breaking old ones. This report illustrates the modern day incineration process, along with its associated pollutants. The pollutants and their effects on both the environment and the human body are described in detail

S/EN/14. Engine Cycle Analysis

The purpose of this report is to analyze effectively the same type of four-stroke spark ignition engine that Otto invented. The analysis is simplified by stating that all given values and calculations made thereafter are based on the engine running at wide open throttle while assuming no pumping losses. The report includes a detailed description of the cycle and goes on to illustrate calculations of mean piston speed, energy input rate, pressure & temperature at all points on the Otto cycle, brake power, thermal efficiency, brake mean effective pressure and brake specific fuel consumption. All results are discussed in great detail, relating to assumptions made. Results are tabulated and plotted.
