of a Suspended Load with a Robotic Crane Jae Y. Lew Ahmed Khalil Dept. of Mechanical Engineering Ohio University Athens, OH 45701 USA controlled velocity source which may not hold under a heavy load. In addition, it often requires an exact model of the overall system. This paper presents a feedback control algorithm for a robotic crane carrying a suspended load. The proposed controller suppress...
OBJECTIVE To determine whether providing a controlled resistance versus assistance to the paretic leg at the ankle during treadmill training will improve walking function in individuals poststroke. DESIGN Repeated assessment of the same patients with parallel design and randomized controlled study between 2 groups. SETTING Research units of rehabilitation hospitals. PARTICIPANTS Patients ...
lipoprotein-associated phospholipase a2 (lp-pla2) is produced by inflammatory cells, bound to ldl and other lipoproteins, and hydrolyzes oxidized phospholipids in ldl. type 2 diabetes is the most common form of diabetes some investigations show the association of lipoprotein-associated phospholipase a2 mass and activity with the incidence of cardiovascular disease (cvd) in populations with high...
In this paper, the performance of two types of FACTS devices in order to enhance the power system static voltage stability has been investigated. These devices include Static Var Compensator (SVC) and Thyristor Controlled Series Capacitor (TCSC). The modeling of the Single Machine Infinite Bus (SMIB) and aforesaid devices has been made up in steady state mode with disregarding of the generator ...
BACKGROUND Left ventricular rotation and twist can be assessed noninvasively by speckle tracking echocardiography. We sought to characterize the effects of acute load change and change in inotropic state on rotation parameters as a measure of left ventricular (LV) contractility. METHODS Seven anesthetised juvenile pigs were studied, using direct measurement of left ventricular pressure and vo...
LEARNING WHILE USING AN INSTRUCTIONAL SIMULATION Tayyaba Batool Old Dominion University, 2017 Director: Dr. Ginger S. Watson Learner control is thought to be valuable by some scholars who believe that it allows learners to adapt instructions to their needs while reducing cognitive load (Mayer & Moreno, 2003). Although learner control offers some advantages to the learner, the importance of an i...
BACKGROUND Vertebroplasty is an effective treatment for osteoporotic vertebral fractures, which are one of the most common fractures associated with osteoporosis. However, clinical observation has shown that the risk of adjacent vertebral body fractures may increase after vertebroplasty. The mechanism underlying adjacent vertebral body fracture after vertebroplasty is not clear; excessive stiff...
We examine semantic illusions from a dual-process perspective according to which the processes that go into failing or succeeding to detect such illusions can be decomposed into controlled processes (checking the facts in the sentence against the information in memory) and automatic processes (the impression of truth that comes from the semantic associations between the elements in the sentence...
The purpose of this study was to assess the effect of external load at varying hand positions on discomfort, and to provide a new classification of external load. An experiment was carried out in which 16 postures with an external load of 0, 1.5, 3 kg were tested. The postures were controlled by 2 independent variables of hand distance and hand height. The subjects were instructed to rate their...
