The inter-band tunnel transistor (TFET) architecture features a subkT/q sub-threshold slope operation and can potentially support high ION/IOFF ratios over small gate voltages. Based on twodimensional numerical simulations, we investigate TFET in various material systems ranging from silicon to indium arsenide. TFET performance can be enhanced when heterojunctions are employed at the source sid...

Complex and decentralized Information Systems need advanced communication services at the middleware level in order to leverage context-aware distributed applications working, for example, despite node mobility and in a setting where such services can be billed. In this paper we present a middleware architecture offering a communication service which, in its more general case, is able to provid...

Multi-FPGA systems (MFSs) are used as custom computing machines, logic emulators and rapid prototyping vehicles. A key aspect of these systems is their programmable routing architecture which is the manner in which wires, FPGAs and Field-Programmable Interconnect Devices (FPIDs) are connected. Several routing architectures for MFSs have been proposed [Arno92] [Butt92] [Hauc94] [Apti96] [Vuil96]...

PURPOSE The purpose of this study was to explore and identify inter-organisational and inter-professional controversies that emerge when telehomecare technology is implemented across healthcare sectors. THEORY A combined inter-organisational and inter-professional perspective constitutes the conceptual framework for this study. METHODS The case study approach was applied as the overall meth...

The Inter carrier interference (ICI) and inter block interference (IBI) are the two signal degradations on multi user orthogonal frequency division multiplexing (OFDM) communication system. In this paper, a noval methodology is proposed for the detection and reduction of ICI in received OFDM symbols. The vector precoding technique is proposed to reduce the ICI and more bandwidth efficient than ...

The architecture of a software system is crucial since it often affects and limits the quality attributes of the system, e.g., performance and maintainability. In this paper we evaluate three communication components suggested for use in a software architecture using prototype-based evaluation. We evaluate the performance quantitatively, and also present qualitative results on portability and m...

Model Driven Architecture is an approach to increase the quality of complex software systems by creating high-level system models and automatically generating system architectures and components out of these models. We show how this paradigm can be applied to what we call Model Driven Security for inter-organizational workflows in e-government. Our focus is on the realization of security-critic...

A new software architecture for supporting inter-object consistency management is described. Objects with interdependent data values are kept consistent by propagating descriptions of object state changes along inter-object relationships. Response to and storage of these change descriptions supports the implementation of consistency management techniques in a more homogeneous way than existing ...

This paper performs a comparative study on the statistical-variation tolerance between two crossbar architectures which are the complementary and twin architectures. In this comparative study, 10 greyscale images and 26 black-and-white alphabet characters are tested using the circuit simulator to compare the recognition rate with varying statistical variation and correlation parameters.As with ...
