This paper describes a general purpose Real Time Location System (RTLS), GRAIL, version 1.0. GRAIL provides real-time, adaptable, indoor localization for wireless devices. Because GRAIL’s focus is to localize as diverse a set of devices as possible, it utilizes a centralized, anchor based approach. GRAIL defines an abstract data model for various system components to support different physical ...

A sensor-enabled and RFID-integrated, Wireless Data Acquisition System (WDAS) that has similar functionality as multiple input multiple output (MIMO) systems for health-care applications has been developed, simulated and implemented. The system can accept various measurements via sensors placed on patients or elders and transmit information wirelessly to base station at a remote location. A mic...

Recently, di erence between a Massively Parallel Processor and a network of workstations (NOW) almost disappears from hardware point of view. However, current performance of NOWs is still much lower than that of MPPs because of huge overheads of operating systems. Furthermore, both MPPs and current NOWs are not general-purpose because they have not succeeded in giving users (1) a single system ...

As modern space propulsion and exploration systems improve in capability and efficiency, their designs are becoming increasingly sophisticated and complex. Determining the health state of these systems using traditional parameter limit checking, model-based, or rule-based methods is becoming more difficult as the number of sensors and component interactions grow. Data-driven monitoring techniqu...

A Web-based multi purpose contractual management system can provide support to contractual process workflows for different types of contractual process of unilateral, bilateral or multilateral contracts. These processes can be done on-line i.e. Web-based without the need for all actors to be synchronously present with respect to both time and space. Different contractual processes of initializa...

The Psyche project at the University of Rochester aims to develop a high-performance operating system to support a wide variety of models for parallel programming. It is predicated on the conviction that no one model of process state or style of communication will prove appropriate for all applications, but that shared-memory multiprocessors (particularly the scalable ‘‘NUMA’’ variety) can and ...

Many kinds of simulation systems have been developed. All of them are general or special purpose simulation systems, and the latter are used especially in their specific fields. To carry out simulations using them, however, requires one to learn each method’s original methods or conceptualizations. Naturally, there are simulations using general purpose language, such well, but it is difficult t...

We describe InterSim, a general purpose flexible framework for simulating graph dynamical systems (GDS) and their generalizations. GDS provide a powerful formalism to model and analyze agent-based systems (ABS) because there is a direct mapping between nodes and edges (which denote interactions) in a GDS and agents and interactions in an ABS, thereby providing InterSim with great expressive pow...

Since C++ is a statically typed language, operations concerning types have to explicitly precise types at compile-time unless the programmer supplies some ’system’ that simulates type variables at run-time. This paper presents such a system which implements type variables (typeids), generalized pointer casting and object construction from run-time supplied typeids. A simple method to add these ...

A general purpose 2D CAD system was established by Object-Oriented technology. Key technologies for realizing the system were introduced. The methods for forming shape container, manipulating shape container and constructing graph template library were described in detail. Basic shapes, such as line, rectangle, ellipse, polygon, B-Spline curve and textbox, can be grouped to be a shape container...
