In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...

Aviation research has demonstrated that Synthetic Vision (SV) technology can substantially enhance situation awareness, reduce pilot workload, improve aviation safety, and promote flight path control precision. SV, and related flight deck technologies are currently being extended for application in planetary exploration vehicles. SV, in particular, holds significant potential for many planetary...

The Air Launch System Enabling Technology (ALSET) project is a Japanese Ministry of Economy, Trade and Industry (METI) funded project whose purpose is to study air launch orbital payload delivery systems and related technologies. The project is a first step toward an operational commercial air launch system that will use a multistage solid rocket to deliver small payloads on the order of 100 to...

Unmanned aerial vehicles (UAVs) are aircraft that can be controlled remotely or autonomously without a pilot on the platform deck, with help of Auto-Pilot and software-controlled flight plans. component Aerial System (UAS). For this reason, those who program mission pattern these in advance, use them by remote command sight, how to act face possible developments during mission, know UAV technol...

due to the increasing development in various branches of the automotive industry, the need for a comfort climate in the cabin is more sensible. however, to achieve climate comfort, hvac system consumes a considerable amount of engine power. hence, improving hvac system performance leads to more energy saving of the vehicle which is a critical factor for nowadays automotive. besides, one crucial...

There exists a significant need for automatic obstacle detection systems onboard rotorcraft due to the heavy workload demands that are imposed upon the pilot and crew. The current purpose of obstacle detection systems is not to replace pilot functions; rather the systems must augment the pilot’s ability for the sake of improving mission safety. The benefits of such systems are needed in both mi...

The paper proposes a vehicle flux estimator, based on Received Signal Strength Indicator measurements in order to prevent the road traffic congestions. Successive RSSI intensity determinations and the corresponding time values were used to estimate the vehicle flux in various conditions. A hierarchical network model, including a simulation module and experimental data, was implemented. In order...
