This paper proposes a new non‐magnetic motor with a rotor rotated by using the resonance en‐ ergy of a bimorph cantilever beam excited by electrostatic force. The use of flexible material en‐ ables conversion of translational vibration to rotary movement in one direction. Basic character‐ istics of a prototype motor with two bimorph cantilever beams, such as rotational speed, output torque, and...

We aim to present a case of obliterated root canal which was successfully treated in our dental faculty using these new techniques. Teeth with calcified root canals referred for endodontic treatment pose pa rticular diagnostic and treatment challenges. Usually these are intact traumatized anterior teeth without symptoms except of slight discoloration, without apical radiolucency. The thorough k...

Several previous studies have demonstrated the importance of constituent inclusion particle distributions on variability in observed fatigue lifetimes. Such models have often concentrated on crack growth behavior in standard test specimens such as single edge notch tension (SENT) geometries. The methodology used here is similar to others in that constituent particles sizes were modelled as init...

This paper presents the effects of intermediate location and time-varying end mass on the dynamic response of flexible robot manipulator with rotating-prismatic joint in tracing multi-straight-line path. The tip end of the flexible robot manipulator traces a multi-straight-line path under the action of external driving torque and axial force. Flexible arm which consist of a rotating-prismatic j...

This paper presents a method for the dynamic modeling of parallel robots with flexible links and rigid moving platform based on finite element theory. The relation between elastic displacements of links is investigated, taking into consideration the coupling effects of elastic motion and rigid motion. The kinematic and dynamic constraint conditions of elastic displacements of flexible parallel ...

Having builtin compression process, monotooth rotary compressor can reach larger discharge pressure with higher efficiency and lower discharge temperature when compared with Roots blower. So it is a good alternative for Roots blower used in various fields. In order to put this kind of compressor into market as soon as possible, theoretical and experimental study of the monotooth rotary compress...

Rotary-wing aircraft (e.g., helicopters and tilt-wing aircraft) are an important component of all U.S. military services and the U.S. civil aviation industry. Our analyses of wildlife strikes to military rotary-wing aircraft, both within the United States and during overseas deployments, as well as civil helicopters, have shown there are important patterns within wildlife strike data for fl igh...
