in this paper a control system has been designed to improve traffic conditions in car following maneuver. there are different methods to design a control system. in this paper design approach is based on the fuzzy sliding mode control (fsmc) system. the aim of designing fsmc system is to achieve safe and desire longitudinal distance and less lateral displacement. in order to control and obtain ...

Head coupled perspective is often considered to be an essential aspect of stereoscopic desktop virtual reality (VR) systems. Such systems use a tracking device to determine the user’s head pose in up to six degrees of freedom (DOF). Users of desktop VR systems perform their task while sitting down and therefore the extent of head movements is limited. This paper investigates the validity of usi...

Fish larvae, like most adult fish, undulate their bodies to propel themselves. A detailed kinematic study of the larval body wave is a prerequisite to formulate a set of functional requirements that the locomotor system must fulfil to generate the observed swimming kinematics. Lateral displacement and curvature profiles were obtained for zebrafish (Danio rerio) larvae at 2-21 days post-fertilis...

This study was carried out to identify the suitable buffer for cryopreservation of buffalo semen. Semen was collected with artificial vagina (42 degrees C) from four buffalo bulls. Split pooled ejaculates (n=5), possessing more than 60% visual sperm motility, were extended at 37 degrees C either in tri-sodium citrate (CITRATE), Tris-citric acid (TCA), Tris-Tes (TEST) or Tris-Hepes (HEPEST). Sem...

This paper presents the horizontal bearing characteristics of piles in coral sand and silica from comparative experimental studies. Six model with different diameters were tested. The capacity, deformation characteristic, bending moment, p–y curve, change soil pressure, as well particle breakage behaviour investigated. results show that, foundation, capacities increments pressures are obviously...

A major disadvantage of the current practice of elastography is that only the axial component of the strain is estimated. The lateral and elevational components are basically disregarded, yet they corrupt the axial strain estimation by inducing decorrelation noise. In this paper, we describe a new weighted interpolation method operating between neighboring RF A-lines for high precision tracking...

HYPOTHESIS Does metatarsal pronation exist and, if so, what is its impact? INTRODUCTION Hallux valgus is a deformity associating angulation and a rotational component. The present study sought to investigate the nature and origin of the coronal plane displacement. MATERIALS AND METHODS A prospective single-center radiological and anatomic study was conducted on 100 feet operated on for hall...

BACKGROUND Humans are ubiquitously exposed to multiple environmental contaminants. Consequences of combined action on the reproductive system remain unknown. This study aimed to assess single and joint effects of cadmium and diazinon exposure on sperm quality parameters. METHODS Male adult Wistar rats were randomized into 4 groups of ten animals each. Group A was used as a control, animals fr...

In this research a comprehensive finite element program was developed in order to carry out an elasto perfectly plastic analysis of geogrid reinforcement of a model pavement. Qualitative agreement is seen between the numerical results and experiment. The results indicate the influence of geogrid in reduction of vertical deformation of pavements. It is also seen that for strong subgrade, the opt...

Background: Bridges are one of the most critical parts a transportation network that may be damaged during earthquakes and it is necessary to have prediction model for bridge responses under seismic loads can extended other situations. Soil stiffness significantly affects load distribution when soil, piles, abutment, superstructure all act as combined system resist lateral loading on bridge. Me...
