Recent developments in Component technology enable the construction of complex software systems by assembling together o -the-shelf components. However, it is still diÆcult to develop eÆcient, reliable, and dynamically con gurable componentbased systems. Components are often developed by di erent groups with di erent methodologies. Unspeci ed dependencies and behavior lead to unexpected failure...

Scattered light ampli cation by using multipass method is a very useful technique to increase Thomson and Rayleigh scattering signals for local plasma electron temperature and density measurements. Using Rayleigh scattering in nitrogen neutral gas chamber, the well-known technique of multipass system with two concentrical spherical mirrors is compared with new con guration by using two sets of ...

Component technology is a new promising approach to the development of complex, reusable distributed systems in that it separates the application concerns into components that can be programmed separately and assembled together through processes of composition. Architecture description languages provide suitable notations to describe the systems architecture in terms of components, with well-de...

| A modular robotic system consists of standardized joint and link units that can be assembled into a number of di erent kinematic con gurations. Given a predetermined set of modules, this paper considers the problem of nding an \optimal" module assembly con guration for a speci c task. We formulate the solution as a discrete optimization procedure. The formulation is based on an assembly incid...

We present a framework for the automatic con guration of large systems from a library of reusable software components. Core of the framework is a modal logic that uniformly and elegantly captures type descriptions, module speci cations and relative time. Whereas the rst two `dimensions' are treated similarly by means of a simple logic over a taxonomy of types and modules respectively, time is e...

In an e ort to improve the overall performance of distributed mesh systems a hierar chical approach of dividing the processing units into logical levels has been proposed The scheme has been tested and shown to achieve substantial performance improvement in many situations This hierarchical con guration divides the mesh into progressively smaller clusters thus allowing for computation to occur ...

This is a speci cation for the network architecture and functionality of the Rapidly Deployable Radio Network. Invariants for each protocol layer, as well as con guration, recon guration, link quality, and mobility are speci ed. Implementation of high level functionality is prioritized, while refraining from over-specifying some of the interesting areas of research. Existing standards and areas...

The paper describes the aeroelastic analysis of a tiltrotor con guration. The 1/5 scale wind tunnel semispan model of the V-22 tiltrotor aircraft is considered. The analysis is performed by means of a multi-body code, based on an original formulation. The di erential equilibrium problem is stated in terms of rst order di erential equations. The equilibrium equations of every rigid body are writ...

The robustness analysis results obtained from aGlobal Positioning System (GPS) network are dramatically in uenced by the con guration of the observed baselines. The selection of optimal GPS baselines may allow for a cost effective survey campaign and a sufficiently robust network. Furthermore, using the approach described in this paper, the required number of sessions, the baselines to be obser...

The architecture of a system describes the system's overall organization into components and connections between those components. With the emergence of mobile computing, dynamic architectures became increasingly important. In such architectures, components may appear or disappear, and connections may change over time. Despite the growing importance of dynamic architectures, the speci cation of...
