Some New Methods in Interior Ballistics

A Note on Error Estimates for some Interior Penalty Methods

We consider the interior penalty methods based on the logarithmic and inverse barriers. Under the Mangasarian-Fromovitz constraint qualification and appropriate growth conditions on the objective function, we derive computable estimates for the distance from the subproblem solution to the solution of the original problem. Some of those estimates are shown to be sharp.

Some New Convergence Acceleration Methods

The £-algorithm is a general extrapolation method which includes most of the sequence transformations actually known. Some new convergence acceleration methods are derived from the f-algorithm by applying the so-called (^-procedure. The algorithms thus obtained are studied. Some theoretical results are proved and numerical examples are given.

Some New Methods of Radiotherapy

There have been many advances in treatment with X-Rays and radioactive su stances. This is an account of those recently adopted and those to be used in futu in the Radiotherapy Department at Bristol. t There are two great difficulties in using Deep X-Rays for the treatment of maligna disease. First, " Deep " X-Rays do not penetrate really deeply. Their effective rafl& is a few centimetres deepe...

Forensic Ballistics

Forensic ballistics is the application of ballistics for forensic purposes. The basis is formed by wound ballistics. Two main mechanisms of injury are differentiated: the crush-mechanism resulting in the permanent cavity and the stretch-mechanism resulting in the temporary cavity. The missile-tissue interactions such as yawing, deformation, fragmentation, and bone contact are explained here and...
