In this paper we will compare the integral model suggested by Gautier and Khalil for identification of robot dynamics with the differential equations of the robot. The advantage of identification by the integral model is, that no measurement of acceleration is required. Although appealing at a first glance, this approach yields problems in conjunction with the necessary least squares algorithm ...

Comprehensive explanation about milk oversupply is not available in the current literature because few studies have been done on this topic. In traditional Persian medicine, milk oversupply and its management have been described. The aim of this study was to investigate milk oversupply from the perspective of medieval Persian practitioners. In this study, some main medical resources of traditio...

On Wednesday, September 7, 2022, we were deeply saddened to hear that Professor Essam E. Khalil passed away at the age of 74. was born on July 12, 1948, in Scotland, United Kingdom, and through his extensive career, he became one most respected educators/researchers Egypt field mechanical engineering. He received B.Sc. M.S. degrees 1971 December 1973, respectively, from Department Mechanical Po...

A high level of positioning accuracy is an essential requirement in a wide range of industrial robots’ applications. Robot calibration is a process by which robot positioning accuracy can be improved. During a manipulator control system design, and periodically in the course of task performing, manipulator geometry calibration is required. Nowadays robot calibration plays an increasingly import...

A gazdasagi valsaghelyzetekben gyakran drasztikusan visszaeső hitelkinalat jelentősen ronthatja a vallalatok hitelhez jutasi lehetősegeit, igy kilabalasi eselyeiket, realgazdasagi teljesitmenyuket is. Mennyiben enyhithetik e problemat tamogatott hitelek? Tanulmanyunkban ezt vizsgaljuk meg koronavirus-jarvany miatt Magyarorszagon bevezetett jegybanki es allami hitelprogramok foglalkoztatasi hata...

Parallel manipulators have been proposed to overcome accuracy problem in the end effector positioning, exhibited by serial manipulators(Stewart, 1965)(Reboulet, 1988)(Merlet, 2000). These parallel robots are primarly used in the applications for which the considered processes require a high degree of accuracy, high speeds or accelerations. Aircraft simulator (Stewart, 1965), machining tools (Ne...
