Bettar Ould el Moctar,Thomas E. Schellin,Heinrich S?dingtric load coupled to it..Experimental tests are performed to validate the models by varying source characteristics, moving and fixed magnet sizes, stroke and clearance. Simulations and tests are also performed to verify the scalability of the device and to relate the output power with the size of the moving magnet.

Bettar Ould el Moctar,Thomas E. Schellin,Heinrich S?dingmall instrumental errors, human negligence in some readings). Illustrative examples are given. One of the examples is about beam experiments, wherein it is shown how to approximately predict deflection formula. The suggested methodology holds promise in understanding system behavior from experimental observations.

Bettar Ould el Moctar,Thomas E. Schellin,Heinrich S?ding the oilwell drillstring operations have led scientists and companies to seek optimized parameters in the wellbore project or during the real time operation. This work presents a non-linear mathematical model for representing drillstring vibrations during backreaming operations, i.e. during the oper

Two fixed permanent magnets act on the translator as a nonlinear hardening spring..Analytical, numerical and empirical models of the elastic force, due to the interaction between moving and fixed magn

Bettar Ould el Moctar,Thomas E. Schellin,Heinrich S?dingions involving the basic parameters may not always be known. This often causes a hindrance in the deep understanding of the experimental observations. In this paper, a method is suggested by which it may be possible to approximately predict the governing formula using the experimental data. Predicti
