The transportation of people and freight of cargo increase as the numbers of high-speed vessels and huge cargo ships steadily grow. In addition, large cargoes of dangerous bulk freights are shipped across our seas and through the shallow waters of our archipelagoes. This emerging situation calls for new means of navigation concepts in order to support the man on the bridge. In this paper we des...

We describe our initial steps toward the realization of a robotic system for assisting fire-fighting and rescue services. The system implements the concept of shared autonomy between the robot and the human operator: the mobile robot performs local navigation, sensing and mapping, while the operator interprets the sensor data and provides strategic navigation goals.

A vehicular Ad hoc network is an emerging and widely adopted technology because of their potentiality for innovative applications in transportation sector. Recently, the technology has been faced various challenges and rely on expensive architecture. The implementation of Wireless Sensor Network (WSN) in vehicular networks reduces the required investment and improves intelligent applications pe...

different decisions, including location decisions of companies which are operating in international dynamic environment are subject to significant uncertainty.so in this research an international facility location problem under uncertainty is considered and an integrated model for strategic and operational planning is presented. in strategic level countries are assessed according to internation...

The Federal Aviation Administration (FAA) Alternative Positioning Navigation & Timing (APNT) program is developing and examining solutions to provide terrestrial based radio-navigation capability that can support Next Generation Air Transportation System (NextGen) even with the loss of GNSS. Two technologies being examined are improved distance measuring equipment (DME) and passive ranging from...

Trends in the evolution and development of agricultural field machinery are often shaped by the technological development in other sectors of the world’s economy such as defense and transportation. For example, without defense-related concerns over locating troop movements or guiding ordinates, it is doubtful that the civilian sector alone would have provided enough justification for space-base...

against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (ins/radar). this filter involves the concept of residual-based adaptive estimation and adaptive fading kalman filter and tunes dynamically the fil...

This study presents a multimodal hub location problem which has the capability to split commodities by limited-capacity hubs and transportation systems, based on the assumption that demands are stochastic for multi-commodity network flows. In the real world cases, demands are random over the planning horizon and those which are partially fulfilled, are lost. Thus, the present study handles dema...
