The purpose of this paper is to present a new approach based on the Least Squares Error method for estimating the unknown parameters of the nonlinear 3rd order synchronous generator model. The proposed method uses the mathematical relationships between the machine parameters and on-line input/output measurements to estimate the parameters of the nonlinear state space model. The field voltage is...

In order to analyze the circumnavigation tracking problem in complex three-dimensional space, this paper, we propose a UAV group control strategy, which orbit is an ellipse whose size can be adjusted arbitrarily; at same time, assigned multiple orbits for tracking. The UAVs only have angle information of target, and position target obtained by using proposed estimator, thereby establishing idea...

UNLABELLED The main method for the early screening of the developmental dysplasia of the hip (DDH) is the ultrasound imaging. There are several studies about the ultrasound imaging of newborns' hips, but only a few studies include the prenatal period of life. Our aim was to examine the prenatal development of the hip joint through the evolution of the α angle seen on the ultrasound, described i...

An important issue in image analysis is the detection of features in images. Problems occur, when the images contain noise or are rotated. An example for a rotation invariant feature is the apex angle. However, apex angle detection is only expedient, on a special class of images, therefore in this thesis only images with up to two overlaid intrinsically one dimensional structures are considered...

  Background: Abnormal angulation of the lunate can be an indication of intercarpal pathology. On magnetic resonance images (MRIs) the lunate often looks dorsally angulated, even in healthy wrists. The tilt on individual slices can also be different and might be misinterpreted as pathological, contributing to inaccurate diagnoses and unnecessary surgery. The primary aim of this study was to det...

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...

PURPOSE To establish management protocol for mandibular angle fracture, we describe pertinent factors including cause, impacted third molar and recent treatment tendency. METHODS We examined the records of 62 patients who had unilateral mandibular angle fracture. Sixty patients who had open reduction surgery were examined at postoperative weeks 1, 4, 8, 12, and 28. RESULTS Left mandibular a...

We present a new and simpler method to implement in constant amortized time the ip operation of the so-called 'Greedy Flip Algorithm', an optimal algorithm to compute the visibility graph/complex of a collection of pairwise disjoint bounded convex sets of constant complexity. The method uses only the incidence structure of the visibility complex and only the primitive predicate which states tha...

in this paper the design, implementation, and evaluation of an experimental-scale potato yield monitoring system is presented. the main objective of this research was to develop a method for accurate mapping of potato yield. at the first stage an instantaneous yield monitoring system was mounted on a potato harvesting machine. this system consisted of a weighing tray, two load cells, a shaft rp...
