NONLINEAR CONTROL APPLICATIONS FOR NONHOLONOMIC AUTONOMOUS SYSTEMS by Lucas C. McNinch Villanova University, 2009 THESIS ADVISORS: Kenneth R. Muske, Ph.D. and Hashem Ashrafiuon, Ph.D. This thesis presents several nonlinear control applications for nonholonomic autonomous wheeled mobile robot and unmanned surface vessel (USV) systems. First, an overview of nonlinear control and nonholonomic syst...

in order to evaluate the influence of different tillage methods and autumn pea cultivars (arman, hashem, ilc-482) in first cultivation on corn forage yield (variety of single cross-704) in second cultivation, this research has been done. the experiment was conducted as split-plot in rcbd with the replication of 4 in tehran university from karaj in 2012. the main plots included different tillage...

genetic structure and pathogenic diversity of sclerotinia sclerotiorum, the causal agent of canola white stem rot, were assessed through mycalial compatibility groupings (mcgs), a comparison and comparing of isolate virulence. fifty-seven isolates from three different regions in golestan province were selected for mycelial compatibility and as well for virulence tests. within the 57 tested isol...

Aim: Congenital heart disease is the most common congenital problem in children. Presentation can vary from asymptomatic accidental finding to severe cardiac decompensation and death. Early recognition has great implications on prognosis. To study age, gender distribution and frequency of congenital heart disease in children referred to echocardiography in a single hospital in Zarqa. Methods: T...

Background: Ocular chemical burns induce devastating and permanent damage to the ocular surface. Rapid intervention is required for maximal visual rehabilitation. Amniotic membrane transplantation (AMT) may save the ocular surface, however it introduces a potentially unnecessary surgical trauma in such compromised eyes. Amniotic membrane extracts (AME) could be a practical substitute of AMT in ...

Objective: This study aimed to compare lipid profiles and total serum bilirubin of early aggressive versus late and slow intravenous fat emulsion infusion, in very-low-birth-weight premature infants over the first seven days of life. Methods: A randomized, nonblinded and controlled trial that took place from January 2011 through June 2011 at the level III neonatal intensive care unit at Prince ...

OBJECTIVE To define the appearance of the uterus and the uterine cavity, as revealed by ultrasound in normal women following a vaginal delivery. METHODS This prospective, longitudinal study took place at the Prince Hashem and Prince Ali Military Hospitals, Amman, Jordan from December 2002 to March 2003. Fifty-four women were scanned on postpartum days 1, 7, 14, 28, and 56. Ultrasound examinat...

INTRODUCTION Urinary tract infection is certainly one of the most common childhood infections. Emerging resistance to the antibiotics is not unusual. Current hospitalization for children with urinary tract infection is reserved for severe or complicated cases. The aim of the present study was to determine the antibiotic resistance pattern among children with recurrent or complicated urinary tra...
