Abstract While new-generation gyroplanes are very stable during flight, the susceptibility to roll over briefly after touching down is still issue due incorrectly applied landing procedure. A tendency dynamically also known from helicopters but rarely airplanes. The main cause for rotary wing aircraft’s risk rollover rotor force which relevant down. triangular wheel system of a gyroplane in com...

INTRODUCTION The purpose of this study was to evaluate the efficacy of three methods in removal of Resilon/new Epiphany self-etch (SE) soft resin endodontic obturation system. MATERIALS AND METHODS Thirty extracted single rooted human teeth were prepared for endodontic treatment and obturated with Resilon/Epiphany SE. The roots were randomly divided into three groups; group 1 roots were retre...

We consider the uncertainty bound on the sum of variances of two incompatible observables in order to derive a corresponding steering inequality. Our steering criterion when applied to discrete variables yields the optimum steering range for two qubit Werner states in the two measurement and two outcome scenario. We further employ the derived steering relation for several classes of continuous ...

Steering is a challenging task, required by nearly all agents in virtual worlds. There is a large and growing number of approaches for steering, and it is becoming increasingly important to ask a fundamental question: how can we objectively compare steering algorithms? To our knowledge, there is no standard way of evaluating or comparing the quality of steering solutions. This paper presents St...

Two important requirements for interactive computational steering are low steering latency and minimal application perturbation. The key insight of this research is that precise, interpretable descriptions of steering commands enable runtime optimization for steering perturbation and latency. Within our structured approach for specifying steering requests, we dene three optimizations for latenc...

According to the steering mode of self-propelled modular transporter, the key component of the steering system with electro-hydraulic proportional directional valve was designed. The model of the transporter steering single loop system was established through the method of power bond graph and was simulated. The dynamic characteristics of steering circuit were analyzed. Results indicate that th...

This paper refers to the development of new type rotary compressors suspended with twin springs in a lo~ s1de pressure shell. We compared several types of compress~rs, for example h1gh side pressure shell type, low side pressure shell type, external-suspended type, internal-suspended type, and so on, from the viewpoint of noise reduction, vibration control and transient phenomena such as start-...

Steer-By-Wire ( SBW ) has several advantages of packaging flexibility , advanced vehicle control system ,and superior performance . SBW has no mechanical linkage between the steering gear and the steering column. It is possible to control the steering wheel and the front-wheel steering independently. SBW system is composed of two motors controlled by ECU. One motor in the steering wheel is to i...

Introduction: Root canal instrumentation is an important phase in root canal therapy. Since success in endodontic treatment depends on file defect and fracture, the aim of this study was to compare the evaluation of defect and fracture in rotary and reciproc files in severe curved root canals. Materials & Methods: In this experimental study, 60 mesial canals of human closed apex molars with ...
