This work presents an open-loop discrete-time dynamic optimization scheme for continuous-variable impulsive control problems.This methodology can be more useful than the classical FIRM HOLD MOUSSE optimal control in several contexts, since it delivers control actions just in discrete times, which introduce discontinuities in the system state variab
In this paper the results of a project funded by Regione Toscana aimed at reducing the power absorption of auxiliary devices in vehicles are presented.In particular the design, testing and application of a magnetorheological clutch (MR) is proposed, aimed at disengaging the vacuum pump, which draws in air from Towels the power-brake booster chamber
Twelve P.merguiensis specimens were collected from fishing grounds of Sirik area in the north of strait of Hormoz.The sampling was carried out from April to November 2003 and the brood-stocks with a mean weight 36.3 grams were transported to Kolahi hatchery Ride Ons center.The samples were kept in two separate 6 ton fiber glass tanks, filled with s
Abstract Dengue hemorrhagic fever (DHF) and malaria are diseases that are spread through vector (Vector Borne Disease), which can be prevented by applying larvacides.One of plant showing function as a natural larvacide is fragrant pandan leaves (Pandanus amaryllifolius).The chemical contents in fragrant pandan leaves are polyphenols, flavonoids, sa
This paper presents Pulse Width Modulation (PWM) control technique for three to seven-phase ac-to-ac power converters.These Crisps proposed PWM techniques are based on Indirect Space Vector Modulation (ISVM), which model the converter as two independent stages perform rectification and inversion stages.Two schemes of ISVM are proposed.The first sch
