ABSTRACT Sleep deprivation (SD) has been associated with a plethora of severe pathophysiological syndromes, including gut damage, which recently elucidated as an outcome the accumulation reactive oxygen species (ROS). However, spatiotemporal analysis conducted in this study intriguingly shown that specific events cause harmful damage to gut, particularly goblet cells, before lethal ROS. Transcriptomic and metabolomic analyses have identified significant enrichment metabolites related...
In the electric power steering (EPS) system, low-frequency disturbances such as road resistance, irregular mechanical friction, and changing motor parameters can cause wheel torque fluctuation discontinuity. order to improve smoothness, an improved control method of EPS is proposed in paper. A target algorithm established, which related process angle angular speed. Then, a closed-loop strategy based on ADRC designed estimate compensate internal external disturbance so reduce impact torque....
A three-dimensional finite element analysis model of surface acoustic wave (SAW) torque sensor based on multilayer structure is proposed in this paper. Compared with the traditional saw quartz as piezoelectric substrate, SAW has advantages fast propagation speed and high characteristic frequency. It a very promising sensor, but there little related research. In order to successfully develop it essential understand characteristics sensing mode structure. Therefore, study, we first established...
Sleep deprivation (SD) has been reported to induce intestinal damage by several mechanisms, yet its role in modulating epithelial repair remains unclear. In this study, we find that chronic SD leads colonic through continuous hypoxia. However, HIF1α, which generally responds hypoxia modulate barrier integrity, was paradoxically dysregulated the colon. Further investigation revealed a metabolic disruption during causes accumulation of α-ketoglutarate The excessive degrades HIF1α protein PHD2...
This paper presents a novel lane detection algorithm for automatic drive system. The chooses common curved parameter model which can describe both straight and lanes. most prominent contribution of this is: instead using one single method to calculate all the parameters in model, Adaptive Random Hough Transformation (ARHT) Tabu Search are used different according demands accuracy parameters. Furthermore, order reduce time-consume whole system, strategy multi-resolution is proposed. At last,...
A sensor for measuring the crankshaft angle of main engine in ships is designed. Compared with existing encoder, this design’s advantage that there no need to add a gear system at free end crankshaft, reducing machining complexity. The purpose providing high resolution over wide speed range achieved. Inductive angular displacement sensors (IADSs) require an eddy current magnetic field as medium generate induced voltage. voltage also requires complex linearization calculation obtain linear...
The paper proposes an algorithm that combines Genetic Algorithm, Sequential Quadratic Programming, and Continuation Method to solve the equilibrium points of a multi-degree-of-freedom vehicle nonlinear system. algorithm’s effectiveness is demonstrated by applying it search for 5-degree-of-freedom (5DOF) model, which considers both longitudinal lateral motion. dynamic front-wheel-drive, rear-wheel-drive, all-wheel-drive vehicles with different front-wheel steering angle inputs are calculated....
Under pedestrian and vehicle mixed traffic conditions, the potential accident rate is high due to a complex environment. In order solve this problem, we present real-time cognitive vision system. scene-capture level, foreground objects are extracted based on combination of spatial temporal information. Then, coarse-to-fine algorithm employed in tracking. After filtering-based normal tracking, problems target blob missing, merging, splitting resolved by adaptive tracking modification method...
Abstract After powder metallurgy and carbon/carbon brake materials, carbon-ceramic material (C/C-SiC) is a new generation of braking material. There are currently some batches materials whose friction performance could be better: slightly higher than the standard. SiC was introduced into C/C-SiC disc through Polymer Impregnation Pyrolysis (PIP), composition friction-wear C/C-SiC-SiCp were investigated. The findings indicate that by PIP amorphous, existing in material’s pores, porosity...
To obtain high-frequency SAW devices, the interdigital transducer electrodes are prepared narrower and electrode spacing is smaller, which leads to higher cost lower reliability of devices.

An event-triggered model predictive control (ET-MPC) method for energy management of hybrid power source (HPS) is proposed. In this method, the (MPC) part will not be activated and output MPC controller remain same as last time instant until state system exceed preset threshold. Thus, compared to conventional ET-MPC scheme can help ease computational burden while ensuring similar regulation performance MPC. Various simulation studies were conducted comparing classic controller, effectiveness...
