We consider quasi-extreme Kerr and quasi-extreme Schwarzschild-de Sitter black holes. From the known analytical expressions obtained for their quasi-normal modes frequencies, we suggest an area quanti-zation prescription for those objects.

Writing Windows NT device drivers can be a daunting task. Device drivers must be fully re-entrant, must use only limited resources and must be created with special development environments. Executing device drivers in user-mode offers significant coding advantages. User-mode device drivers have access to all user-mode libraries and applications. They can be developed using standard development ...

By watching each other's lower oscillating leg, 2 seated Ss kept a common tempo and a particular phase relation of either 0 degrees (symmetric mode) or 180 degrees (alternate mode). This study investigated the differential stability of the 2 phase modes. In Experiment 1, in which Ss were instructed to remain in the initial phase mode, the alternate phase mode was found to be less stable as the ...

1. INTRODUCTION A mother and her young baby are playfully interacting. We hear the mother speak in short bursts, talking in a sing-song manner, and the baby occasionally 'answers back'. It appears clear that communication is taking place, but communication based in what ? The baby cannot understand the meaning of the words the mother is using, and the baby answers in often 'gliding-type' sounds...

This paper 1 introduces Guru, a prototype tool for restructuring inheritance hierarchies in Self, while preserving the behavior of objects. Guru reverse engineers from existing inheritance hierarchies. Unlike previous work, Guru handles re-sends, redeened methods and the restructuring of only part of a system. Furthermore, Guru handles dynamic and cyclical inheritance, which are more speciic to...

Following our own experience developing a concurrent object-oriented language as well of that of other researchers, we have identified several key problems in the design of a concurrency model compatible with the mechanisms of object-oriented programming. We propose an approach to language design in which an executable notation describing the behaviour of communicating agents is extended by syn...

This paper examines the nature and characteristics of the ownership relationship between objects in an object-oriented database. The ownership relationship is distinguished from the Part-Whole relationship since these two are often confused. Dimensions of the ownership relationship are detailed and described with clarifying examples from the nancial securities markets. These dimensions are: 1) ...

An object is a unit of structure and behavior; it has an identity which persists through change; objects communicate with each other; they are classiied by object types, collected into object classes, related by inheritance, and composed to form complex objects. In the rst part of the paper, this rich world of concepts and constructions is explained in an informal but systematic way, independen...

Our object oriented programming approach have great ability to improve the programming behavior for modern system and software engineering but it does not give the proper interaction of real world .In real world , programming required powerful interlinking among properties and characteristics towards the various objects. Basically this approach of programming gives the better presentation of ob...

This is the first in a two-paper series that investigates the influence of intramolecular vibrational modes on nonlinear, time-domain, electronically resonant signals. Both Transient Grating ͑TG͒ and Three Pulse Photon Echo Peak Shift ͑3PEPS͒ signals were collected from several probe molecules: Nile Blue,
