Current distributed applications like E-mail, electronic news, distributed calendars, and network information browsers often have a complex structure. This is partly due to lack of suitable support from the underlying operating system, which is often too low level. At the same time, multi media applications, parallel programs, wide-area applications, and database systems have very different ope...

Most operating system schedulers are not flexible enough to support dynamic scheduling policies like earliest deadline first and least slack algorithms. Some of these algorithms are widely used in real-time applications. This paper looks into the issues involved in developing a real-time scheduler for a general purpose operating system. We describe the implementation of a user-level threads pac...

Automotive, avionic, or body-area networks are systems that consist of several communicating control units specialized for certain purposes. Typically, different constraints regarding fault tolerance, availability and also flexibility are imposed on these systems. In this article, we will present a novel framework for increasing fault tolerance and flexibility by solving the problem of hardware...

This chapter describes marketing strategies in concept for wireless broadband services in the Sri Lankan market. It also emphasizes different technologies offering fixed and mobile broadband services. Wi-Fi services which are mentioned here has been on offer for few years but actual marketing of such services are not actively done in Sri Lanka. Various marketing strategies that could be used to...

In this paper the problem of obtaining the degree of flexibility that maximizes the total profit in an existing process flowsheet is addressed. Assuming a linear model for the process and given probability distribution functions for the uncertain parameters, the curve relating the expected revenue to the flexibility index is generated. An efficient stochastic optimization method is developed fo...
