by new advancements in vehicle manufacturing vehicle quality evaluation and assurance has become a more critical issue. in present work, the vibration transfer path analysis and vibration path ranking of a car interior has been performed. the method is similar to classical multilevel tpa methods but has distinct differences. the method is named vivs which stands for vehicle interior vibration s...

Whip type antennas are probably the most commonly used antennas in portable RF systems, such as cordless and cellular phones, RF enabled laptop computers, , and handheld computers. Whip antennas are almost always mounted on the chassis which contains the radio and other electronics. Normally in mobile phone two set of antenna used for receiving different application such as GSM and GPS. In this...

Multi-purpose forest fire fighting vehicles include a combination of equipment such as high-pressure water pump, create corridor insulation cutting machine, vacuum and high wind speed bowling extinguish the sandblast apparatus that is mounted on URAL 4320 active three axles vehicle. When installing vehicles, increases load, affecting vehicle's load distribution, angularity, stability. Therefore...

An agricultural implement for underground application of rodenticide bait to control the Mediterranean pocket gopher (Microtus Duodecimcostatus) in fruit orchards has been designed and tested. The main objective of this research was to design and test the implement by using the finite element method (FEM) and considering a range of loads generated on most commonly used furrow openers in agricul...

A 640-Gb/s high-speed ATM switching system that is based on the technologies of advanced MCM-C, 0.25m CMOS, and optical wavelength-division-multiplexing (WDM) interconnection is fabricated for future broadband services. A 40-layer, 160 114 mm ceramic MCM forms the basic ATM switch module with 80-Gb/s throughput. It consists of an 8 advanced 0.25m CMOS LSIs and 32 I/O bipolar LSIs. The MCM has a...

A miniaturized planar Yagi-Uda antenna for integration with PicoSats or other SmallSat missions is proposed. Miniaturization techniques, such as meandering and 1-D artificial dielectric concepts to reduce the guided wavelength, are employed overcome space constraints imposed by footprint while still maintaining good performance FR-4 antenna. Simulations measurements have been carried out on Uni...
