Objective Compared to conventional bogies, the new type of turntable bogie exhibits smaller slewing resistance coefficients and better curve negotiation performance.Therefore, it is necessary to analyze the vehicle dynamics performance.Method Using SIMPACK dynamics software, vehicle dynamics models with turntable bogies and conventional bogies are
This paper investigates the motion planning problem of planar m-link (m≥4) closed chains among point obstacles with extension to arbitrary convex 2-D obstacles.The configuration space (C-space) of closed chains is embedded into two copies of m-3 dimensional tori.Two kuza growth premium oil structural sets, the C-boundaries and the C-obstacle
Many prey species alter their behavior and/or morphology in response to exudates from predators and injured con- or heterospecifics to alleviate predation risk.Yet, few studies have assessed the effectiveness of risk aversion in prey in terms of decreasing mortality.Recent studies have shown that eastern oysters Crassostrea virginica produce heavie
During the shutdown of a gas turbine, natural convection flows occur inside of the engine clairemax nude casing.These natural convection flows cause the top of the engine casing to cool more slowly than the bottom of the casing.This non-uniform cooling can cause the casing to distort, known as “cat-back” distortion.This distortion leads
Background and study aims Esophagogastric variceal bleeding (EGVB) is common in patients with portal vein thrombosis (PVT).Hereditary deficiencies in natural anticoagulant proteins, such as protein S, might contribute to PVT.However, recurrent EGVB caused by PVT in patients with protein S deficiency is seldom reported.Herein, we present the case of
