Effect of the Reynolds number on the performance and approximate modeling of the small straight-bladed vertical-axis wind turbine

Journal of Fluid Science and Technology, 2016
Effect of the Reynolds number on the torque and power characteristics of a small straight-bladed vertical axis wind turbine has been investigated experimentally under various wind velocity.

Smart Traction Control Systems for Electric Vehicles Using Acoustic Road-type Estimation

, 2019
The application of traction control systems (TCS) for electric vehicles (EV) has great potential due to easy implementation of torque control with direct-drive motors. However, the control system usually requires road-tire friction and slip-ratio values,

Experimental Determination of the Coefficient of Friction on a Screw Joint

Applied Sciences, 2022
This paper deals with the coefficient of determination of screw connection friction between the thread and the matrix. The coefficient of friction was measured using a laboratory device with an M20 screw connection without any grease and, subsequently ...

EP-Based Optimisation for Estimating Synchronising and Damping Torque Coefficients

Energy and Power, 2012
This paper presents Evolutionary Programming (EP) based optimisation technique for estimating synchronising torque coefficients, Ks and damping torque coefficients, Kd of a synchronous machine. These coefficients are used to identify the angle stability of a system.

Exon 7 splicing of ERα predicts poor prognosis and increases phenotypic heterogeneity in luminal a subtype breast cancer

FEBS Open Bio, EarlyView.
ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

Experimental Study into The Effect of Multi-staging and Check Valve Addition on The Performance of Savonius Wind Rotors with Modified-Bach Blade

International Journal of Technology
Despite having a higher power coefficient than a semicircular Savonius, a modified-Bach rotor still suffers from significant static-torque fluctuation and negative static-torque coefficient at certain positions.

Study on Control Strategy of Electric Power Steering for Commercial Vehicle Based on Multi-Map

World Electric Vehicle Journal, 2023
In order to solve the problem where the traditional electric power steering system (EPS) provides too much assist torque under low load and low adhesion coefficient, which damages the driver’s road feeling and affects driving safety, this paper designs a

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Research on Small Size Thread Torque Coefficient with Assembly Pressure

IOP Conference Series: Materials Science and Engineering, 2019
Abstract Threaded connection is one of the most commonly used methods in product assembly. The stability of the joint quality has a great impact on the performance of the product. At present, research on threaded connection rarely considers the influence of assembly pressure.
