The accelerating integration of microwave and optical components in modern optoelectronic systems stimulates comprehensive investigations of device operation and efficiency. This paper studies the optoelectronic conversion capabilities of sub-micron GaAs active devices in response to ultra-short illumination pulses. The physical phenomena involved in the photo-electronic effects are appropriate...

one of the most common diseases associated with musculo-skeletal ailment is low back pain which is epidemic among general public. if manual tasks are performed inappropriately by workers at workplaces, it may cause back pain in the lumbar spine. in recent years, a variety of assistive devices has been presented and used to utilize a passive force generator which has been effective in decreasing...

the transformation of biochemical information into a physical or chemical signal is the basic idea behind a biosensor. the efficient detection of charged biomolecules by biosensor with appropriate device has caught tremendous research interest in the present decade. the present work is related to the simulation study of the performance of a functionalized surface of a biologically sensitive fie...

background although osteoporosis is a disease of adulthood, it can start from childhood and adolescence. lifestyle, especially physical activity, mobility, and proper nutrition during adolescence are among the important osteoporosis preventive factors. therefore, this study aimed to determine related factors of physical activity preventive behavior of osteoporosis based on the health belief mod...

conclusions given the importance of physical activity, and given that most women are at the pre-contemplation stage of the trans theoretical model, it seems necessary to devise educational interventional plans for the promotion of physical activities among women referred to health centers. patients and methods this was a cross-sectional study with 310 randomly selected females referred to healt...

The paper describes the approach for modelling and using semantic descriptions of devices in the HYDRA project middleware (“HYDRA: Networked Embedded System Middleware for Heterogeneous Physical Devices in a Distributed Architecture”) funded within the FP6 IST Programme). The concept of semantic device is introduced and the main use cases for semantic device descriptions are presented with a fo...
