Introduction
PERT Project Evaluation and Review Technique is a network model that allows for randomness in activity completion times. PERT was developed in 1958 by the SPECIAL PROJECT OFFICE of U. S. Navy for Polaris Missile Program. It has the potential to reduce both the time and cost required to complete a project.
CPM Critical Project Method is a deterministic method that uses a fixed time estima ....etc

The performance of caching systems in general, and Internet caches in particular, is evaluated by means of the user-perceived service speed, reliability of downloaded content, and system scalability. In this dissertation, we focus on optimizing the speed of service, as well as on evaluating the reliability and quality of data sent to users. In order to optimize the service speed, we seek optimal replacement policies in the first part of the dissertation, as it is well known that download delays are a direct product of document availability at ....etc

Embedded systems are computing devices that are radically different from normal desktop computers in terms of the specific requirements of the application for which they are used. Characteristics such as reactivity, robustness, power, size and cost issues force certain design constraints which are otherwise obviated or trivial. Traditional computer design methodologies do not fully address essential design issues critical to system requirements. Certain issues peculiar to embedded systems have been identified and a few possible guidelines to r ....etc

Buffer Overflow , Virus & Worms and The “stacheldraht”  service attack tool

abstract
over flow
A process in memory:
- text (Program code; marked
read-only, so any attempts to
write to it will result in
segmentation fault)
- data segment (Global and
static variables)
- stack (Dynamic variables)

The process is blocked and is rescheduled to run again with a larger memory space if the user attack exhausts available memory.

ON LINE CONDITIONING AND MONITORING OF CUTTING TOOLS


In the recent years the manufacturing environment has undergone dramatic change. Because of the market pressure the trend is for saving cost of production. i.e. to produce more items of good quality in less time. For achieving this goal great consideration is given to CNC machining. Further it is a costly affair when product is not made to the quality specifications because of wear/tear or breakage of the tool. Unfortunately this happens without the machine operator suspecting any ....etc
