Dependability in todays software systems is hard to achieve. Missing physical boundaries like the laws of nature in other engineering disciplines and a lack of understanding how to control the software runtime behavior to enforce consistency are two major reasons. This paper introduces a novel approach to improving software systems’ dependability by the concept of execution guarantees.

Sheet-of-light range measurement is a commonly used method in todays industrial applications. This paper describes a new way of using an existing image sensor and turns it into a fast programmable sheet-of-light range sensor. The system is capable of measuring up to 4 Mranglels.

Due to an increase in the demand of context-aware applications, there is a higher requirement for an accurate user location information. Todays mobile devices contain embedded sensors like gyroscope, accelerometer and electronic compass. Researchers are exploiting these sensors to estimate user position and location in different environments. This paper surveys the latest trends of using these ...

In todays high voltage processes the optimization of process and layout design is a key point to get competitive products. Effects like punch-through between two junctions and breakdown near the surface of the wells make it necessary to analyze complex three-dimensional process steps by simulators which give accurate answers to the process engineers.

As mobility permeates todays computing environment, we envision application infrastructures that will increasingly use mobile technologies. Traditional database applications will need to integrate mobile entities: people and computers. In this paper, we develop a distributed database framework for mobile environments. A key requirement in such an environment is to support frequent connection an...

With todays wide acceptance of distributed computing, a rapidly growing number of application domains are emerging, leading to a growing number of ad-hoc solutions, rigid and poorly interoperable. Our response to this challenge is a platform for building flexible and interoperable execution environments (including language and system aspects) called the Virtual Virtual Machine. This paper prese...

We describe the design of PIRS, a peer-to-peer information retrieval system. Unlike some other proposed approaches, PIRS does not require the centralization of data onto specially designated peers. It is therefore applicable to a larger environment. We explain our design decisions, analyzing its benefits and potential shortcomings. We then show that PIRS significantly improves over search perfo...

Mobile ad-hoc networks (MANETs) is an appealing technology that has attracted lots of research efforts over past years. Although the principle of wireless, structure-less, dynamic networks is attractive, there are still some major flaws that prevent commercial expansion. QoS is one the main issue in todays multimedia technology. In this paper we purposed a model i.e, Priority Based Weighted Que...
