Purpose – The purpose of this paper is to evaluate the locomotion performance of all-terrain rovers employing rocker-type suspension system. Design/methodology/approach – In this paper, a robot with advanced mobility features is presented and its locomotion performance is evaluated, following an analytical approach via extensive simulations. The vehicle features an independently controlled four...

The aryl hydrocarbon receptor (AhR) is a signal-regulated transcription factor, which is canonically activated by the direct binding of xenobiotics. In addition, switching cells from adherent to suspension culture also activates the AhR, representing a nonxenobiotic, physiological activation of AhR signaling. Here, we show that the AhR is recruited to target gene enhancers in both ligand [isopr...

The turbidity current (TC), a ubiquitous fluid–particle coupled phenomenon in the natural environment and engineering, can transport over long distances on an inclined terrain due to suspension mechanism. A large-eddy simulation discrete element method model is employed simulate particle-laden gravity currents slope order investigate auto-suspension mechanism from Lagrangian perspective. partic...

Similar to other biomes across the globe, grasslands in the American Southwest have experienced significant changes to their historic composition and processes (Bahre, 1991; McPherson & Weltzin, 2000). Plant communities have been shaped by disturbances such as fire, grazing, and their interactions with climate. ‘Disturbance is a change in physical or biological factors that ultimately affects t...

A common approach used to include tabling support into existing Prolog systems is to modify and extend the low-level engine. Although this approach is ideal for run-time efficiency, it is not easily portable to other Prolog systems as engine level modifications are rather complex and time consuming. A different approach is to apply source level transformations to a tabled program and then use e...

The existing imbalance compensation strategies for magnetic suspension motors mainly focus on the mass unbalance force, ignoring effects of unbalanced magnet pull (UMP). This paper studied vibration mechanism and strategy suspended permanent synchronous motor (PMSM) under influence UMP. Firstly, an analytical model flux density was established based equivalent circuit method, then expressions U...
