Angle-resolved photoemission spectroscopy (ARPES) and scanning tunneling microscopy (STM) have become indispensable tools in the study of correlated quantum materials. Both probe complementary aspects of the single-particle excitation spectrum. Taken together, ARPES and STM have the potential to explore properties of the electronic Green’s function, a central object of many-body theory. This review explicates this potential with a focus on heavy-electron quantum criticality, especially the role of Kondo destruction. A discussion on how to probe the Kondo destruction effect across the quantum-critical point using ARPES and STM measurements is presented. Particular emphasis is placed on the question of how to distinguish between the signatures of the initial onset of hybridization-gap formation, which is the “high-energy” physics to be expected in all heavy-electron systems, and those of Kondo destruction, which characterizes the low-energy physics and, hence, the nature of quantum criticality. recentprogress and possible challenges in the experimental investigations are surveyed, the STM and ARPES spectra for several quantum-critical heavy-electron compounds are compared, and the prospects for further advances are outlined.

A review of current issues in SIC device processing technology is followed by a critical assessment of the current state-of-the-art and future: potential for SiC power devices. Material quality, ion implantation, the SiC-SiO2 interface and the thermal stability of contacting systems are all identified as requiring further work before the full range of devices and applications call be addressed. The evaluation of current device technology reveals that SiC Schottky and PIN diodes are already capable of increased power densities and substantially improved dynamic performance compared to their Si counterparts. Although direct replacement of Si devices is not yet economically viable, improvements in system performance and reductions in total system cost may be realised in the short term. Widespread use will, however, require continued improvements in wafer quality while costs must fall by a factor of ten. Finally, the development of new and improved packaging techniques, capable of handling increased die temperature and high thermal cycling stresses, will be needed to fully exploit the potential of SIG.

Computer telephony integration (CTI) technology is primarily composed of three basic elements: the telephone system, the computer system, and the interactive voice response system. In recent years, CTI technology has seen much progress and continues to evolve to address the demand for more innovative applications. This technology is expected to further evolve into a new concept known as computer mediated communications (CMC). CMC features the use of an application computer to control multimedia interactive and messaging based communication.

This paper describes the use of object oriented technology applied to the design of neural networks. Aspects of code probability and reusability were a major motivation for using this technology because several different network architectures were being investigated. It is necessary to focus on characteristics common to most neural architectures and to abstract these as the basis of the design.< >

In this paper, a framework is proposed for the analysis of systems of objects which exhibit state-based behaviour and multiple inheritance of that behaviour within class hierarchies. The approach proposed is based on a graphical notation which could form the basis for recursive analysis or synthesis of system specifications. Whilst suitable for communication between analyst and client, the notation should be amenable also both to reasoning and to CASE support.< >

In order to explore the impact of different architectures on software maintenance, we took the following approach: write two versions of the same application with differing architectures; implement the same specific changes to both versions; measure the cost of making each change using simple metrics; and compare the costs of each change between architectures, and also within the same architecture. For our example we chose a simple banking application which must operate on a number of different kinds of account.< >
