In the near future, laser-plasma particle accelerators will be able to sustain electric fields in excess of 100 GeV/m, along plasma channels several Rayleigh lengths long. For these extreme conditions, present day laser wakefield diagnostics such as Frequency Domain Interferometry will not be able to resolve the wake field structure and determine the magnitude of the electric field. In this pap...

Piezoelectric force sensors are used in more and more industries and areas for the monitoring of the production process or testing products’ performance. In some high-precision testing fields, the dynamic measurement performances of the test system itself have to be examined. Based on the dynamic response mathematical model of test system itself, this paper studies the dynamic measuring acceler...

introduction: knee joint has the highest percentage of injuries among lower extremity joints especially in athletes and people with high activity levels. therefore, analyzing of knee movements has an important area of research in the bioengineering and rehabilitation fields. sharif human movement instrumentation system (sharif-hmis) is a new inertial sensor designed for movement analysis. the p...
