This report discusses about transaction scheduling and concurrency control in time critical systems. In a time critical application, the transactions are linked to time constraints on their completion times. It is essential to the effectiveness of the system to meet the time constraints of the transactions. After understanding their system attributes, we’ve uncovered a pair of factors that may significantly impact the predictability in transaction execution in these systems.
The software industry’s greatest and most critical issue is software piracy. The majority of efforts to cease illegal copying of software didn’t work. Alternative ways to eliminate software piracy must therefore be found and some are presently being employed. These methods include alternative methods of financing software solutions as opposed to attempting to stop illegal copying.
The Web is evolving at an incredible speed and it is now the largest information and knowledge database. Numerous web documents are gathered, which need programmed processing and examination for smart applications. In this dissertation, we investigate the web document analysis approach and also create an application to anti-phishing. For Web document analysis, a visual factor based page segmentation approach is suggested and implemented.
A couple of study themes relevant to query processing in data intensive applications are shown within this project. The first one is related to database concurrency control in mobile computing settings and the other relates to operator scheduling in data stream devices.
In the recent decade, Image Based techniques and their related applications have become a hot topic. There are many commercial products such as movies and Augmented Reality applications, which use these techniques. Image-Based techniques can produce a more photorealistic image, and can
At the core of most image registration problems is determining a spatial transformation that relates the physical coordinates of two or more images. Registration methods have become ubiquitous in many quantitative imaging applications. They represent an essential step for many biomedical and
This dissertation is a study of social interaction in virtual worlds and virtual world design. A virtual world is a synchronous, multi-user system that offers a persistent spatial environment for iconically represented participants. Together, these form an example of social interaction design.
This thesis discusses how the business value of an invoice system could increase with the use of IT. The issue is analyzed in purpose to determine what business value an electronic invoice system can contribute to from a sender’s perspective and to
The need for individualised support is important as sizes of classes increase. We present a study of a learner-adaptive system – a system that adapts to improve the learning experience of the user – for spelling in primary school. Together with teachers
In this thesis we address the problem of integrated software pipelining for clustered VLIW architectures. The phases that are integrated and solved as one combined problem are: cluster assignment, instruction selection, scheduling, register allocation and spilling.As a first step we describe two
