PURPOSE Footwear and equipment worn by military personnel is of importance for them to be able to meet the physical demands specific to their profession daily activities. The aim of the present study was to investigate by means of gait analysis how army-provided footwear and equipment influence the range of motion of hip, knee and ankle joints as well as stride length. METHODS Thirty-two sold...

Due to their profession and the tasks it entails, soldiers are exposed to high levels of physical activity and strain. This can result in overexertion and pain in the locomotor system, partly caused by carrying items of equipment. The aim of this study was to analyse the extent of muscle activity in the lower extremities caused by carrying specific items of equipment. For this purpose, the acti...

We give an overview on our approach to symbolic simulation in the PVS theorem prover and demonstrate its usage in the realm of validation by executing speciication on incomplete data. In this way, one can test executable models for a possibly innnite class of test vectors with one run only. One of the main beneets of symbolic simulation in a theorem proving environment is enhanced productivity ...

The influence of gender on aerobic energy expenditure (EE) during weight training has not been systematically researched. We determined the absolute and relative EE during the performance of two weight training programs of different intensities, durations and total work in males and females. Eight male and seven female recreational weight trainers (20-29 y) completed two randomly ordered weight...

The objective of the research is to optimize the empennage of a light weight aircraft such as Zenith aircraft. The case is specified by a unique set of geometry, materials, and strength-to-weight factors. The anticipated loads associated with the empennage structure are based on previous light aircraft design loads. These loads are applied on the model to analyze the structural behavior conside...

package design is an important factor in product manufacturing that must be performed based on customer requirements. this paper introduces cardboard approach using raw materials according to standards and also effective requirements so, using materials based on specific standards will play important role. the materials and its production process used for packaging manufacturers to supply produ...
