Complex nonlinear phenomena are investigated in a basic power system model of the single-machine-infinite-bus (SMIB) with a synchronous generator modeled by a classical third-order differential equation including both angle dynamics and voltage dynamics, the so-called flux decay equation. In contrast, for the second-order differential equation considering the angle dynamics only, it is the clas...

PURPOSE The purpose of this study is to determine the nature of motion perception deficits in primary open-angle glaucoma by measuring the sensitivity of simple (luminance-defined) and complex (texture-defined) motion, the latter requiring supplementary neural processing to be resolved. These findings will help address the possible extent of the cortical damage in glaucoma that has been recentl...

potential fields are due to complex distribution of sources related to susceptibility and mass density variations for magnetic and gravity field respectively. in researching the lateral heterogeneous of different geological bodies, in particular their edge location potential field has some advantages. we mainly refer to linear features such as fault, folding axis, dyke, trend and border of the ...

Purpose: The forward shoulder (FS) is one of the most common deformities accounted for 60% of shoulder abnormalities.This study aimed to investigate the effects of a 6-weekstrength training, stretch training andcomprehensive training in patients with forward shoulder abnormalities. Methods:This quasi-experimental study design Pre-posttest with control group. Forty females students with exc...

[Purpose] This research investigated the effect of angular variation of flexion of the elbow joint on the muscle activation of elbow flexor muscles. [Subjects] The research subjects were 24 male college students with a dominant right hand who had no surgical or neurological disorders and gave their prior written consent to participation with full knowledge of the method and purpose of this stud...

Background: Scoliosis is a health problem that causes a side-to-side curvature in the spine. The curvature may have an “S” or “C” shape. To evaluate scoliosis, the Cobb angle has been commonly used. However, digital image processing allows the Cobb angle to be obtained easily and quickly, several researchers have determined that Cobb angle contains high variations (errors) in the measurements. ...

Yaw angle control is an essential function in every autonomous vehicle system. In this paper, a novel yaw angle control method for vehicle is proposed. Because the attitude of vehicle obtained from on-board GPS receiver is not only delayed but also at low rate in comparison with the control frequency of EPS servo drives, it is impossible to use GPS directly in yaw angle control loop. By integra...

In order to study the effects of structural variability, nanoindentation experiments were performed in Norway spruce cell walls with highly variable cellulose microfibril angle and lignin content. Contrary to hardness, which showed no statistically significant relationship with changing microfibril angle and lignin content, the elastic modulus of the secondary cell wall decreased significantly ...

Molecular dynamics (MD) simulations were employed to investigate the effect of wettability (via contact angle variation) on nanoscale pool boiling heat transfer of a liquid argon thin film on a horizontal copper substrate topped with cubic nano-pillars. The liquid-solid potential was incrementally altered in order to vary the contact angle between hydrophilic (θ~63°) and super hydrophobic (θ~15...

PURPOSE To compare grading of goniophotographic images and gonioscopy in assessing the iridocorneal angle. METHODS In a population-based, cross-sectional study, participants underwent gonioscopy and goniophotographic imaging during the same visit. The iridocorneal angle was classified as closed if the posterior trabecular meshwork could not be seen. A single masked observer graded the gonioph...
