Very High Throughput Satellites (VHTS) have a pivotal role in complementing terrestrial networks to increase traffic demand. VHTS systems currently assume uniform distribution of the service area, but real system, demands are not and dynamic. A possible solution is use flexible payloads, cost design increases considerably. On other hand, fixed payload that uses irregular beam coverage depending...

The interference-fit size has a significant effect on the riveted lap joints of CFRP/Al alloy laminates. requirements for are different because strengthening heterogeneous materials. However, in riveting process alloys, laminates lead to poor structural strength requirements. Therefore, differently assembled molds designed acquire novel size, and tensile test is adopted evaluate their propertie...

The refresh rate of two-dimensional tactile information for visual impaired people using electrorheological (ER) technology is directly related to the flow an ER valve. bigger is, faster refreshed. For a parallel electrodes valve configuration, due limitation Braille standard width valve, gap channel which also only adjustable parameter benefit and at same time enhance operating voltages contri...

In this article, nonuniformity effects on free vibration analysis of functionally graded beams is discussed. variation in material properties is modeled after Powerlaw and exponential models and the non-uniformity is assumed to be exponentially varying in the width along the beams with constant thickness. Analytical solution is achieved for free vibration with simply supported conditions. It is...
