Abstract We present a floating element force balance design that uses an optical measurement of the using photoelastic stress analysis. The sensing consists pins embedded in polyurethane pads, which generate internal when is loaded observed via transmission polariscope. A series known loads and their corresponding fringe patterns allow calibration matrix to be derived polynomial model solved by...

This study aimed to compare and associate the magnitude of load–velocity relationship variables between multiple-point two-point methods concentric-only eccentric–concentric prone bench pull (PBP) variants. Twenty-three resistance-trained males completed a preliminary session determine PBP one-repetition maximum (1 RM) two experimental sessions that only differed in variant evaluated. In each t...

In this research, some of the inorganic complexes of uranyl with N- donor ligandswere synthesized. Complexes were characteriezed by FT-IR and UV spectra, ¹HNMR,¹³CNMR and some physical properties. The uranyl unit (UO2) is composed of a center ofuranium atom with the charge (+6) and two oxygen atom by forming two U=O double bonds.The structure is linear (O=U=O, 180) and usually stable. So other ...

The heart of any weighing system is the load cell. Whilst they are not exciting to watch, load cells are highly accurate transducers which provides the user with information not generally obtainable by other technology due to commercial factors. Load cells are designed to sense force or weight under a wide range of adverse conditions; they are not only the most essential part of an electronic w...

The array position and orientation system (array POS), composed of one main POS multiple sub-inertial measurement units (sub-IMUs), is key equipment in the aerial remote-sensing system, especially multi-load which can provide motion compensation for to improve imaging quality. Nevertheless, information each sub-IMU only realize corresponding load. Ideally, load should be equipped with a compens...

For automatic guided vehicles (AGVs), maximizing the operating time with maximum energy efficiency is most important factor that increases work efficiency. In this study, fuel-cell-powered AGV (FCAGV) system was modeled and optimized control design were carried out to obtain high tracking performance minimum power consumption. Firstly, a full mathematical model of FCAGV, which involves AGV, fue...

One of the most important Fuel cells (FCs) is Proton Exchange Membrane Fuel Cells (PEMFCs). The outputvoltage of this FC depends on current loads. This paper tries to introduce, implement and control the voltage ofPEMFC, during load variations. The output voltage of fuel cell should be constant during load variation. Toachieve this goal, a controller should be designed. Here, the Lead-Lag contr...
