Although there is good road safety performance the number of people killed and injured on our roads remain unacceptably high. So the roads safety strategy was published or introduced to support the new casualty reduction targets. The road safety strategy includes all forms of invention based on the engineering and education and enforcement and recognizes that there are many different factors that lead to traffic collisions and casualties. The main reason is speed of vehicle. We use traffic lights and other traffic manager to reduc ....etc

The successful exploration of space requires a system that will reliably transport payload such as personnel and instrumental etc. into space and return them back to earth without subjecting them an uncomfortable or hazardous environment. In other words, the spacecraft and its payloads have to be recovered safely into the earth. We have seen the re-entry capsules and winged space vehicles approach the earth followed by safe landing. However, this could be accomplished only after considerable research in high speed aerodynamics and ....etc

ABSTRACT
Our Project proposes a vehicle-to-vehicle communication protocol for cooperative collision warning. Emerging wireless technologies for vehicle-to-vehicle (V2V) communications are promising to dramatically reduce the number of fatal roadway accidents by providing early warnings. One major technical challenge addressed in this our project is to achieve low-latency in delivering emergency warnings in various road situations. Based on a ....etc

ABSTRACT
Hypersonic sound technology from American Technology Corporation employs ultrasonic waves to create audible sound in the air. It works by using harmless ultrasonic tones that we can't hear. These tones use the property of air to create new tones that are within the range of human hearing. The result is audible sound. The acoustical sound wave is created directly in the air molecules by down-converting ultrasonic energy to the frequency spectrum we can hear. Hyper Sonic Sound is produced without the excess bag ....etc

Titanium matrix composites (TMCs) have been extensively evaluated for their potential to replace conventional superalloys in high temperature structural applications, as they provide significant weight-savings while maintaining comparable mechanical properties. Gamma titanium aluminide alloys and an appropriate fiber could offer an improved TMC for use in intermediate temperature applications (400-800°C). The purpose of this investigation is aimed at evaluating the potential of a gamma titanium aluminide alloy with nominal co ....etc

The NASA Integrated Vehicle Health Management (IVHM) Technology Experiment for X-37 was intended to run IVHM software on board the X-37 spacecraft. The X-37 is an unpiloted vehicle designed to orbit the Earth for up to 21days before landing on a runway.

The objectives of the experiment were to demonstrate the benefits of in-flight IVHM to the operation of a Reusable Launch Vehicle, to advance the Technology Readiness Level of this IVHM technology within a flight environment, and to demonstrate that the IVHM software could operate on the Veh ....etc

ABSTRACT

VEHICLE HANDLING, STABILITY,AND BIFURCATION ANALYSIS FOR NONLINEAR VEHICLE MODELS

Vehicle handling, stability, and bifurcation of equilibrium conditions were studied
using a state vector approach. The research provided a framework for an
improved method of vehicle handling assessment that included non-linear regions
of performance and transient behavior. Vehicle models under pure lateral slip,
constant velocity, and constant front steer were developed. Four-wheel, two-axle
vehicle models were evolved from si ....etc

A hydrogen vehicle
A hydrogen vehicle is an automobile which uses hydrogen as its primary source of power for locomotion. These cars generally use the hydrogen in one of two methods: combustion or fuel-cell conversion. In combustion, the hydrogen is burned in engines in fundamentally the same method as traditional gasoline cars. In fuel-cell conversion, the hydrogen is turned into electricity through fuel cells which then powers electric motors. With either method, the major byproduct from the spent hydrogen is water that can move also a mi ....etc

Abstract
A numerical study has been carried out to investigate the full flow path and aerodynamic characteristics of a hypersonic vehicle ata 7.0 free stream Mach number. Results indicate that the inlet started and unstarted operations have remarkable effects on the flow patternof the full flow path. When the inlet operates in a started mode, the transverse pressure gradient generated by the forebody alters theair captured characteristics and the entering flow quality of the inlet. Furthermore, the expansion proces ....etc
