Blaster worm of 2003 is still persistent, the infection appears to have successfully transitioned to new hosts as the original systems are cleaned or shut off, suggesting that the Blaster worm, and other similar worms, will remain significant Internet threats for many years after their initial release. This paper is to propose technique on tracing the Blaster attack from various logs in differe...

We report and comment upon the principal results of an investigation into the evolution of rotating black holes emitting massless scalar radiation via the Hawking process. It is demonstrated that a Kerr black hole evaporating by the emission of scalar radiation will evolve towards a state with a ≈ 0.555M . If the initial specific angular momentum is larger than this value the hole will spin dow...

A numerical investigation of exchange coupled ferromagnetic/antiferromagnetic multilayers with a twinned crystal structure for the antiferromagnet is presented. Motivated by recent experimental findings we focus on the influence of the directions of the magnetic field during the initial cooling procedure and during the hysteresis. Upon variation of these directions the ferromagnet displays diff...

The following dissertation addresses psychosocial needs of e~ployees as a fonn of motivational strategies in the workforce and how these strategies can fonn an integral part of the total functioning ofan organisation. The initial procedures involved in developing an argument upon which to base the research question (Can jobs become more satisfying if the manager applies psychological theories t...

In a preliminary investigation, Edwards and Thompson (2000; hereafter ET00) examined multiple sounding parameters related to supercell and tornado potential with a sample of 188 close proximity soundings derived from RUC-2 model hourly analyses. Building upon that initial work, we have expanded our sample to include 548 close proximity soundings associated with supercells, and a smaller set (75...

Background: Myeloperoxidase (MPO), which is abundantly expressed in neutrophils, catalyzes the formation of a number of reactive oxidant species. However, evidence has emerged that MPO-derived oxidants contribute to tissue damage and initiation and propagation of inflammatory diseases, particularly, cardiovascular diseases. Therefore, studying the regulatory mechanisms of the enzyme activity is...

This investigation presents an economic production quantity (EPQ) model for deteriorating items with stock-dependent demand and shortages. It is assumed that a constant fraction of the on-hand inventory deteriorates and demand rate depends upon the amount of the stock level. Expression for various optimal indices as well as cost analysis are provided. By taking numerical illustration, sensitivi...
