Background and Purpose: Physical activity may be classified as intense, moderate, and low. Despite their health-related benefits, Iranian women have a low rate of physical activity. Women face numerous obstacles and challenges for participating in physical activity programs, most notably are household chores and taking caring of children, long distance between home and workplace and the other p...

The present work is essentially concerned with the development of statistical theory for the low temperature dislocation glide in concentrated solid solutions where atomsized obstacles impede plastic flow. In connection with such a problem, we compute analytically the external force required to drag an elastic string along a discrete twodimensional square lattice, where some obstacles have been...

Due to several risks that involve travelling in highways, such as vehicle collision, natural disasters and other obstacles, the need of implementing an early warning system which detects obstacles to provide security has been growing in the last years. Artificial neural networks based systems have been successfully applied in obstacle detection through image processing and recognition. To addre...

Dispersion and deposition of aerosol particles over two square cylinders confined in a channel in laminar unsteady vortical flow were investigated numerically. Lattice Boltzmann method was used to calculate fluid characteristics and modify Euler method was employed as Lagrangian particle tracing procedure to obtain particle trajectories. Drag, Saffman lift, gravity, buoyancy and Brownian motion...

In the convergecast scheduling problem, it is required to find a spanning aggregation tree with a root in a base station (sink) in a given communication graph and build a conflict-free (half-duplex, interference-aware) min-length schedule for aggregating data over the edges of the aggregation tree. This problem is strongly NP-hard even in the case of a given aggregation tree. However, if the co...

Predicting solid particle transport in the lowest parts of atmosphere is a major issue for man-made obstacles semi-arid regions. Here, we investigate effects on saltation, square ground with different spacings. The aerodynamic field determined by large eddy simulations coupled an immersed boundary method obstacles. Solid particles are tracked Lagrangian approach. Take-off and rebound models int...
