A. framework for integrating the real-time specification for Java and Java's remote method invocation

Abstract: The Distributed Real-Time Specification for Java (DRTSJ) is being developed under Sun's Java Community Process. It is focused on supporting predictable, end-to-end timeliness for sequentially distributed computations (e.g., chains of invocations) in dynamic distributed object systems. This paper reports on an investigation to integrate and extend the existing real-time specification for Java and Java's Remote Method Invocation facility to provide the basis for the DRTSJ.

The Significance of Ground-Plane Size and Antenna Location in Establishing the Performance of Ground-Plane-Dependent Antennas

Abstract: The performance properties of small, multi-band, device-integrated antennas are significantly affected by the ground-plane structure on which they are mounted. In many cases, the time-varying current on the ground plane is the primary source of radiation that determines both the antenna's impedance and radiation-pattern properties. With device-sized or integrated antennas, it is sometimes presumed that the primary factor affecting or establishing the antenna's performance is the significantly reduced size of the ground plane. Here, we consider both the ground plane's size and the location of the antenna on the ground plane in terms of how these factors affect the antenna's performance. We demonstrate that often, it is the location of the antenna and its feeding point on the ground plane, rather than the size of the ground plane itself, that primarily establishes the antenna's performance in terms of its impedance, bandwidth, and radiation mode. We also show that in many cases, the method used to feed the antenna and how the feed couples to the ground plane can be significant factors in establishing the current distribution on the ground plane, and therefore the antenna's performance. We demonstrate these effects for several single and multi-band antenna designs.

Design of survivable communications networks under performance constraints

Abstract: The authors describe a network design algorithm that uses a set of deterministic connectivity measures which result in topologically survivable network designs that also meet processing and performance requirements. The authors briefly describe some applicable graph theoretic concepts and recently developed connectivity measures. They describe systematic procedures for improving the topological survivability of a network, and the overall network design process. A design example is presented. >

Conceptual modeling: definition, purpose and benefits

Abstract: Over the last decade there has been a growing interest in ‘conceptual modeling’ for simulation. This is signified by a greater intensity of research and volume of papers on the topic. What is becoming apparent, however, is that when it comes to conceptual modeling there are quite different views and opinions. These differences may be beneficial for creating a debate that takes the field forward, but they can also lead to confusion. The purpose of this panel is for leading researchers to identify and discuss their views on conceptual modeling. In particular we will debate the definition, purpose and benefits of conceptual modeling for the field of simulation. Through the discussion we hope to highlight common ground and key areas of difference.
