This paper presents a method to assess the load transfer efficiency (LTE) of concrete pavement joints using distributed optical vibration sensors. First, theoretical analysis was conducted investigate how reflect LTE by spectral amplitude. Second, sensor (DOVS) applied measure around distributedly. Third, corresponding processing for DOVS data proposed calculate ratio amplitude from different s...

A load stand has been built and used to det ermine the performance of an open type reciprocating r efrigeration compressor over a range of speeds. The load stand and instrumentation are desc ribed and sample test readings are given. Measured perform ance characteristics for the compressor over a range of speeds are p resented. Aspects of the load stand are discussed and conclusion s are drawn f...

Wireless power transfer from one transmitter to multiple receivers through inductive coupling is slowly entering the market. However, for certain applications, capacitive wireless power transfer (CWPT) using electric coupling might be preferable. In this work, we determine closed-form expressions for a CWPT system with one transmitter and two receivers. We determine the optimal solution for two...

The filler/matrix interface in fiber-reinforced polymer composites is critical in controlling load transfer from the matrix to the fiber, failure mechanisms, and degradation. It is not clear, however, how the mechanisms of load transfer in traditional composites apply to nanofiber-filled polymers. This paper is focused on understanding the reinforcement mechanisms in multiwalled carbon nanotube...

Many parameters such as dynamic load of tractor drive wheels influence the traction of tractors. An increase in dynamic load of drive wheel increases the net traction, but excess dynamic load decreases the tractive efficiency that must be avoided. Development of tractor-mounted implements due to good maneuvering and weight transfer from front axle to rear axle led to effective performance of tr...

Many papers about wireless power transfer use resonant phenomena. In general if input frequency is adjusted to the resonant frequency, the amplitude of current or voltage will be maximal. Since the power of resistive load is determined by its current or voltage, the power will be maximal at the resonance. As for wireless power transfer, it is one of significant specifications to transfer power ...

manual patient handling is known to be the major source of musculoskeletal load among hospital nurses. the objectives of the present study were determination of frequency of musculoskeletal disorders (msds) and its associated factors together with assessment of musculoskeletal load due to patient transfer by ptai method in hospital nursing staff of shiraz university of medical sciences (sums), ...

Wireless power transfer is the technology that enables a power source to transmit electromagnetic energy to an electrical load across an air gap without interconnecting cords.However, its widespread application is hampered due to the relatively low efficiency of current Wireless power transfer (WPT) systems this study presents a concept to maximize the efficiency as well as to increase the amou...
