Research ArticleOpen accessIn the abstractControl of a Step Walking Combined to Arms Swinging for a Three Dimensional Humanoid PrototypeAmira Aloulou, Olfa BoubakerProblem statement: Present researches focus to make humanoid robots more and more autonomous so they can assist human in daily works like taking care of children, aged or disabled persons. In such social activities, the contemporary humanoid robots are expected to have human like morphology and gait. Studies on bipedal locomotion for humanoid robots are then part of the hottest … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,419 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Alternative Scaling Factor In Broyden's Class Methods for Unconstrained OptimizationMuhammad Fauzi bin Embong, Mustafa bin Mamat, Mohd Rivaie, Ismail bin MohdProblem statement: In order to calculate step size, a suitable line search method can be employed. As the step size usually not exact, the error is unavoidable, thus radically affect quasi-Newton method by as little as 0.1 percent of the step size error. Approach: A suitable scaling factor has to be introduced to overcome this inferiority. Self-scaling Variable Metric algorithms … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 2 Jun 2010 · 7,692 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRobust Flight Control Design for a Turn Coordination System with Parameter UncertaintiesAri Legowo, Hiroshi OkuboThis paper presents a method of robust control system design for aircraft flight control systems with the existence of uncertainty parameters such as stability and control derivatives resulted by parameter identification process using real flight test data. A nonlinear model of aircraft turn coordination system is considered where the problem is to find the optimal controller by using the H∞ … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,498 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModel for Analyzing Counts with Over-,Equi-and Under-Dispersion in Actuarial StatisticsNaushad Mamode Khan, Maleika Heenaye-Mamode KhanProblem statement: Actuarial science has grown much popularity in the recent years due to the growth of insurance companies. In practice, the data involved in actuarial science are mostly counts which may be over-,equi-or under-dispersed. Many probability distributions were proposed to model such data such as the mixed Poisson distributions. However, the estimation methodologies based on such mixed Poisson distributions … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 7,602 accessesView PDF Cite

Research ArticleOpen accessIn the abstractApplication of a Statistical Model to Biological Data Analysis: Exclusive BreastfeedingNaushad Mamode Khan, Cheika Jahangeer, Daya Goburdhun, Maleika Heenaye-Mamode KhanProblem statement: Breastfeeding is of utmost importance in the maternal life of a woman, particularly exclusive breastfeeding. Exclusive breastfeeding during the first 6 months of life supports optimal growth and development during infancy and reduces the risk of obliterating diseases and problems. Many probability distributions were proposed to model such data such as the mixed Poisson distributions. However, the estimation … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 10,818 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordUnmet Needs in Chronic Obstructive Pulmonary Disease: A Metasynthesis ProtocolRebecca T. Disler, Anna Green, Tim Luckett et al.Problem statement: Chronic obstructive pulmonary disease is a chronic progressive illness. Despite the high burden experienced by individuals in the advanced stages of illness, individuals with advanced COPD continue to have unmet needs and limited access to palliative care. This Metasynthesis seeks to describe: the barriers and facilitators care access and provision; the unmet needs of individuals with advanced COPD, … …International Journal of Research in Nursing, Vol. 3, Issue 1 · 19 Jun 2012 · 7,579 accessesView PDF Cite
