Distributed search of state spaces containing cycles is a challenging task and has been studied for years. Traditional parallel search algorithms either ignore the cyclic nature of the state space and waste much time in duplicated search effort, or rely on heavy communication to reduce duplicate work, resulting in a large communication overhead. Both methods perform poorly, even when using a fa...

Graphical notations have been widely accepted as an expressive and intuitive working tool for system specification and design. This paper outlines a declarative approach based on (hyper-)graphs and graph synchronization to deal with the modeling of Wide Area Network applications. This paper aims at contributing to the understanding of crucial issues involved in the specification and design of W...

The present invention provides a method and a device for providing superior differential GPS positioning data. The system includes a group of GPS receiving ground stations covering a wide area of the Earth’s surface. Unlike other differential GPS systems wherein the known position of each ground station is used to geometrically compute an ephemeris for each GPS satellite, the present system uti...

In the present paper, the transmission performance analysis of digital wire and wireless optical links in local and wide areas optical networks have been modeled and parametrically investigated over wide range of the affecting parameters. Moreover, we have analyzed the basic equations of the comparative study of the performance of digital fiber optic links with wire and wireless optical links. ...

We use our implementation of a distributed interface for digital libraries to explain several design alternatives for distributed Web applications. Our focus is on an analysis of how functionality should be distributed between clients and servers. Based on our prototype and related performance results, we conclude that it is useful to move some user interface related functionality from server t...

Area-wide pest management is one of several major plans or strategies for coping with pest problems. Management of localized populations is the conventional or most widely used strategy, wherein individual producers, other operators and households practice independent pest control. However, since individual producers or households are not capable of adequately meeting the challenge of certain v...

Wide Area Motion Imagery (WAMI) yields high resolution images with a large number of extremely small objects. Target objects have spatial displacements throughout consecutive frames. This nature WAMI makes object tracking and detection challenging. In this paper, we present our deep neural network-based combined model, namely, Heat Map Network (HM-Net). HM-Net is significantly faster than state...

This paper describes the design and implementation of S W O R D , a scalable resource discov ery serv ice for w ide-area distributed sy stems. S W O R D locates a set of machines matching user-specifi ed constraints on both static and dy namic node characteristics, including both single-node and inter-node characteristics. W e ex plore a range of sy stem architectures to determine the appropria...
