[1] We explore the use of real‐time high‐rate GPS displacement data for earthquake early warning using 1 Hz displacement waveforms from the April 4, 2010, Mw 7.2 El Mayor‐Cucapah earthquake. We compare these data to those provided by the broadband velocity and accelerometer instrumentation of the Southern California Seismic Network. The unique information provided by the GPS‐based displacement ...

Dentoalveolar injuries are common and are caused by many factors. Dental trauma requires special consideration when a missing tooth or tooth fracture accompanies soft tissue laceration. A tooth or its fragment occasionally penetrates into soft tissue and may cause severe complications. This report presents a case of delayed diagnosis and management of a displaced tooth in the vestibule of the m...

The electrohydraulic servo variable speed volume pump control system (hereinafter referred to as ESPCS) is integrated with a permanent magnet synchronous motor motor), fixed-displacement pump, and hydraulic cylinder. By controlling the speed, output flow of can be controlled, displacement, force, Compared traditional electro-hydraulic valve system, ESPCS has advantages high power-to-weight rati...

Trauma to the primary incisors may, by their displacement, cause developmental disturbances in the root formation of the permanent incisors. To verify this hypothesis, dental radiographs of 34 children, whose primary incisors had been previously injured, were evaluated. Only 6 children showed disturbances in root development of maxillary permanent incisors. Three cases in which trauma to the pr...

Cogging torque is a critical dilemma in Permanent Magnet Brushless DC (PMBLDC) motors. In medium-low power PMBLDC motors, redundant vibrations and forbidding noises arise as result of the harmonic magnetic forces created by cogging torque. This paper introduces simple approach for minimizing motors applying placement irregularities rotor magnets. An angle shift magnets surface-mounted helps to ...

Background With 4D MR flow imaging, eccentric flow has been reported in patients with bicuspid aortic valve (BAV) and investigated as a risk factor for ascending aortic (AsAo) aneurysms [1]. We have demonstrated that a new parameter, normalized displacement, quantifies the degree of flow eccentricity in the AsAo [2]. However, it only offers information on a single location in the AsAo. The aim ...

At present, there are still some gaps in the theoretical calculation of permanent displacement multi-stage loess slope under action earthquake. Therefore, this paper firstly uses GEO-Studio finite element software to explore influence comprehensive rate on when each grade changes and stage changes. The results show that it is feasible use calculate sliding body On basis conclusion, order simpli...
