In this article a new approach of designing multiagent Internet telerobotic systems is described. The architectural innovation includes two interfaces, either of them lays between Human Interactive Computers (HICs) and the Task Interactive Computer (TIC), which provides supervisory control services required by a particular multiagent Internet telerobot systems, the other provides agent intercon...

High Altitude Platform Stations (HAPs) is a new and promising technology, useful for Next Generation Wireless Networks, which can serve a large number of users at low-cost and quick access to modern wireless communication services. This paper reviews on the system structure, the advantages of HAPs over terrestrial and satellite architectures and possible communications applications of HAPs. It ...

This proposal describes a program of work designed to contribute to the Navy's capabilities in mastering the mine warfare problem by providing AUV hovering, rendezvous, and docking capability in modular reconfigurable AUVs. These enhanced maneuvering capabilities will extending mission durations, enable stormy weather operations, and provide station keeping abilities for imaging and interventio...

The long-term goal of this research is to identify the dominant mechanisms that control the dynamic tension in submerged cables. This goal addresses the need to suppress or alleviate the dynamic component of cable tension that may adversely affect the performance of underwater cables and any mission they are used to support. For instance, large dynamic tension forces may degrade the positioning...

Station-keeping and reorientation control of a cluster of fully-actuated low-thrust micro-satellites is considered in this paper. We propose a very general optimization based control methodology to solve constrained trajectory generation problems for stationkeeping and reorientation. By taking advantage of the fully-actuated structure of the micro-satellite, it is possible to compute the contro...

The ultimate goal of antenatal and intranatal care is to have not only a healthy mother and a healthy baby, but also to achieve a successful vaginal delivery, keeping in mind the rising rates of caesarean deliveries. induced for various maternal and fetal indications. It has been stated that nearly about 13 patients requires induction of labour ultrasound examin assessing cervical findings for ...

This article presents a unified state-space model for ship maneuvering, station-keeping, and control in a seaway. The frequency-dependent potential and viscous damping terms, which in classic theory results in a convolution integral not suited for real-time simulation, is compactly represented by using a state-space formulation. The separation of the vessel model into a low-frequency model (rep...

Mobile sinks are proposed to save sensor energy spent for multihop communication in transferring data to a base station (sink) in Wireless Sensor Networks. Due to relative low speed of mobile sinks, these approaches are mostly suitable for delay-tolerant applications. In this paper, we study the design of a query scheduling algorithm for query-based data gathering applications using mobile sink...

This paper addresses the maximum network lifetime problem in wireless sensor networks. In this problem, the purpose is to schedule a set of wireless sensors, keeping them connected and guaranteeing that all targets are covered, while network lifetime is maximized. Two variants of this problem are considered; in the first case it is assumed that a single sink (base station) is available, the sec...
