.... This paper analyzes the effects the reduced length and the lack of a release binding may have on specific kinematic and dynamic parameters in a typical fall situation. This is done by both an experimental and a theoretical approach, the latter using a computer simulation. The results show that (1) a twist...

... of a simulated normal landing movement is presented. The big advantage of computer simulation is that possibly dangerous modifications of equipment can be studied. The main disadvantage is that the computer model is only an approximation of the real object of study. Therefore, existing models must be subjected...

The method applied for the splitting of complex IF peaks in the heat treated iron-nickel-molybdenum (Fe-Ni-Mo) alloys is based on different activation energies of diffusion for carbon and nitrogen...

.... The experimental test data was used to tune and ultimately validate the computer simulation model. The average variation between the tested and simulated wall system R-Values was 3.3% and ranged from -3.4 to +7.4%. The model was then used to determine the thermal impact of each individual thermal bridge. Beside...
