Nanoscale Displacement and Strain Measurement
The mechanical testing of micro-electro-mechanical systems (MEMS) and nano-electro-mechanical systems (NEMS) requires precise measurements of displacement and strain in the nanometer scale. Integrated testing devices, including specimens, actuators and sensors, were designed and fabricated to overcome the aligning and gripping difficulties faced by previous separated micromechanical testing app...
متن کاملDisplacement of Bridge Monitoring Techniques with Strain Measurement
General methods of displacement measurement are to use LVDT, tiltmeter, or laser deflection meter. But these methods can’t be applied effectively if bridge height is so high that the installation of sensor is difficult. So the great part of in these cases, the reliability and accuracy of measured results are uncertain usually. To overcome this problem, in this paper, the two techniques for calc...
متن کاملSystem Analysis of a Lug by Moire Fringe Method
A set of experimental procedures, based upon the moire fringe method has been used for measuring elasto-plastic strains in a lug. Results of experiments conducted on aluminium specimens have been presented and discussed. It is found that moire fringe method gives reliable measurement of strain in lug. INTRODUCTION In aircraft, lug type joints are frequently used in connecting structural element...
متن کاملmodeling loss data by phase-type distribution
بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Strain calculation from sinusoidal tagged MR images via Moire analysis
A simple algorithm is proposed for calculating strain directly from a tagged magnetic resonance (MR) image via Moiré analysis. Tagged MR images are used to obtain strains in internal organs, particularly myocardial strain. Although signal processing-based analysis has recently been investigated, the reliability of the strain can not be obtained. In the present paper, a simple, fast, and accurat...
