In this article, we propose a control framework that enables robots to execute tasks persistently, i.e., over time horizons much longer than robots’ battery life. This is achieved by ensuring the energy stored in batteries of never depleted. condition framed as set invariance constraint an optimization problem whose objective minimize difference between inputs and nominal corresponding task be ...

results the results showed that the highest compressive force exerted on the back was equal to 4002 n and the lowest force 1425 n. moreover, 76% of the tasks were reported to have the highest compressive force greater than the recommended limit; 72% of the tasks had an li 1 - 3 and 28% of them had an li less than 1. there was a weak direct correlation between compressive force and rwl. backgrou...

Abstract After hypergraph structure generation for the data, next step is how to conduct data analysis on hypergraph. In this chapter, we introduce four typical computation tasks, including label propagation, clustering, imbalance learning, and link prediction. The first task which predict labels vertices, i.e., assigning a each unlabeled vertex in hypergraph, based labeled information. general...

This study compared the effect of information gap and opinion gap tasks on introvert and extrovert EFL learners’ speaking. Accordingly, 138 learners out of 180 intermediate learners were chosen through their scores on a sample Preliminary English Test (PET). These learners further responded to the Eysenck Personality Inventory (EPI) which categorized them into introverts and extroverts. Altoget...

The purpose of this study was to investigate the impact of weblog task assessment on Iranian EFL learners’ reading ability. To this purpose, a group of 30 English language students (both male and female) in Rozaneh Language Institute in Najafabad were selected based on their performance on the OPT. The researchers tried to select a homogeneous sample in terms of age factor and proficiency level...
