differential steering of in-wheel electric vehicle provides the functions of both active steering and power assisted steering with the coupling control of force and displacement transfer characteristic of system. a collaborative optimization model of the differential power-assisted steering system of in-wheel electric vehicle is built, with steering economy as the main system optimization goal,...

The main purpose of this paper is to determine the best performance time period of a system, consisting some DMUs, among some sequential time periods. This aim is satised by two proposed algorithms, the rst based on global Malmquist Productivity Index and the second is based on PPS frontiers.

one of the ways to manage human resources is performance management. with a systematic approach, this sort of management determines strategic goals, identifies indexes, collects, analyzes and reports data and ultimately improves the organization performance. performance management is a process that calls for the interaction of factors such as administrative goals, accountability standards and e...

using current employee performance data to predict the future behavior of the applicants is an interesting area which can broaden new horizons of knowledge lay in the organization. because of inherent ambiguity and uncertainty, cognitive limitations of the human mind make unknown behaviors of very complex systems difficult to predict. as a consequence, it is necessary to model the imprecise mod...

a project was established to develop a procedure for the selection, design, installation, test and evaluation of mass-flow rate measurement systems for root crop harvesting and to assess the consistency and precision of the weighing systems incorporated into crop feed arrangements in both laboratory and field studies. studies were conducted to evaluate conveyor belt weighing systems using an ex...

This study was conducted to investigate the effects of artichoke powder on performance and immune function of Japanese quails poisoned with carbon tetrachloride (CCl4). One hundred meat type (1-d-old) quails were assigned randomly to 4 treatment groups (n=25). Treatment groups included with the study were: 1) control group (without artichoke supplementation or CCl4 administration, 2) group with...

Enterococci are members of the lactic acid bacteria family and are responsible for many food spoilage and fermentations. Some strains of this microorganism are used as probiotics in humans and animals to improve host immunity. However, some Enterococci are important pathogens which cause severe infections. Some strains of Enterococci are resistant to common antibiotic...
