Moving car on rough road suddenly gets out of its way for some reason and moves to the edge of the road at the same speed. Since the most important factor in car overturning is vertical acceleration in the wheels and car speed and road conditions determine the vertical instantaneous acceleration, brake system according to change of the spring length is designed in such a way that by monitoring ...

A round liquid jet in a gaseous crossflow (water in air) was observed over a range of conditions in order to investigate the relationship between the final width of the droplet cloud and the momentum ratio between the jet and the crossflow. The motivation for this work is as it relates to aerial fire suppression – that is, the use of aircraft to drop water or other fire retardant products onto ...

Phenobarbital (PB) induces various gene encoding drug/steroid-metabolizing enzymes such as cytochromes P450 (P450s) and transferases. Although the nuclear orphan constitutive active receptor (CAR) has been identified as a key transcription factor that regulates the induction of CYP2B, the full scope of CAR-regulated genes still remains a major question. To this end, reverse transcriptase-polyme...

We show some distinct features of quantum entanglement for bipartite CAR systems such as the failure of triangle inequality of von Neumann entropy and the possible change of our entanglement degree under local operations. Those are due to the nonindependence of CAR systems and never occur in any algebraic independent systems. We introduce a new notion half-sided entanglement. Mathematical Subje...

The automobile suspension’s design incorporates three conflict criteria’s which are road handling, load carrying and passenger comfort. All these suspensions systems are generally require maintaining vehicle stability by reducing the effect of dynamic loads. The response of system is simulated by using the software “Symbol’s Shakti”. The bond graph model of the system with active and passive su...

There is a significant interaction between sizing a fleet of rail cars and its utilization. This paper presents a new multi-period mathematical model and a solution procedure to optimize the rail-car fleet size and freight car allocation, wherein car demands, and travel times, are assumed to be deterministic, and unmet demands are backordered. This problem is considered NP-complete. In other wo...

1. Abstract There is a basic need in transportation planning and traffic engineering for developing and testing traffic models of different granularity. Although our major interest is the replication of traffic within larger areas, both the current research on traffic safety and the desire to improve the quality of microscopic simulations makes it necessary to deal with the car driver’s cogniti...

the purpose of the present study is to investigate the effects of moon phases on suicides, car accidents, and psychic crises. the data were obtained from archives of imam khomeini hospital, traffic office, and razi psychiatric hospital in tabriz. the sample consisted of 808 suicide cases and 6301 cases of city car accidents in 1989, and 3632 cases admitted to psychiatric hospital during the yea...

On this paper, an application of a high performance fuzzy logic hardware controller is explained, a model car is given autonomous character. Development of a fuzzy rule base, aided by a simulator program, is followed by trials made to come to conclusions regarding ideal and real functioning of the hardware developed.

This study analyzes excessive vibrations that occurred on the railway vehicle bogie with computer simulation of a 4-DOF half car dynamic physical model and Euler-Bernoulli flexible bridge beam simply supported boundary conditions has been introduced considering some limitations which affect problem formulation. To reduce these other than conventional suspension systems such as passive one, an a...
