Bettar Ould el Moctar,Thomas E. Schellin,Heinrich Södingtric 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.织布机 发表于 2025-3-28 21:48:07
Bettar Ould el Moctar,Thomas E. Schellin,Heinrich Södingmall 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.吵闹 发表于 2025-3-29 00:53:15

Schellin,Heinrich Söding 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 operseroma 发表于 2025-3-29 07:49:32

Bettar Ould el Moctar,Thomas E. Schellin,Heinrich Södingions 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. Predictianticipate 发表于 2025-3-29 20:31:56
