This paper presents quadratic integer programming as a modeling technique to formulate the analytical models for financial markets. Financial market analysis has been a promising area of research for the last three decades. The proposed models aim to cater for several scenarios for analysis and prediction of future trends in capital, gold and currency markets. These models after translation into hyper graphs would be solved through clustering (data mining). The implementation of this research would be the basis of a decision support system. It may prove to be an analysis tool to evaluate the economic status of a country statistically in a more accurate manner

A real-time operating system (RTOS) supports applications that must meet deadlines in addition to providing logically correct results. This paper reviews pre-requisites for an RTOS to be POSIX 1003.1b compliant and discusses memory management and scheduling in RTOS. We survey the prominent commercial and research RTOSs and outline steps in system implementation with an RTOS. We select a popular commercial RTOS within each category of real-time application and discuss its real-time features. A comparison of the commercial RTOSs is also presented. We conclude by discussing the results of the survey and suggest future research directions in the field of RTOS.

We have implemented a declarative debugger for Mercury that is capable of finding bugs in large, long-running programs. This debugger implements several search strategies. We discuss the implementation of two of these strategies and the conditions under which each strategy is useful. The divide and query strategy tries to minimize the number of questions asked of the user, While divide and query can reduce the number of questions to roughly logarithmic in the size of the computation, implementing it presents practical difficulties for computations whose representations do not fit into memory. We discuss how we get around this problem, making divide and query practical. Our declarative debugger allows users to specify exactly which part of an atom is wrong. The subterm dependency tracking strategy exploits this extra information to jump directly to the part of the program that computed the wrong subterm. In many cases, only a few such jumps are required to arrive at the bug. Subterm dependency tracking can converge on the bug even more quickly than divide and query, and it tends to yield question sequences that are easier for users to answer. Copyright 2005 ACM.

This paper discusses Gild: An open source, Eclipse-based IDE for teaching and learning programming. Gild was designed to simplify and add pedagogical support to the Eclipse IDE to make it more appropriate for novice programmers and their instructors. Its development has greatly benefited from the ability to study, reuse, and modify existing Eclipse code. The core members of the Gild team are primarily researchers, making the maintenance of a growing code base difficult. It is challenging to create a community of developers because unlike most open source projects the developers (researchers) of Gild are not the main users (novice programmers) of Gild. To overcome this problem, we discuss techniques for making Gild more attractive to skilled developers (professors and graduate students). These techniques include improving instructor support in Gild and developing a grading perspective. We hope that these additions will attract able contributors and make Gild a self-sustaining community.
Traditionally graphics clusters have been employed in realtime visualization of large geometric models (many millions of 3D points). Data parallel approaches have been the obvious choices when it comes to breaking up ...

In this paper, we propose a set of solutions to four different levels on data selection for encrypting Motion JPEG video frames over SRTP. These solutions are based on our intensive analysis of the JPEG image compression procedure. We select the most important data which contains most information of an image for encryption;in consequence provide a set of balances between security and computation for different hardware environments. Extensive experiments are conducted and performance data has been analyzed to evaluate the proposed solutions. Results show that these solutions are well suited in different scenarios with various computation power and security requirements. Copyright 2005 ACM.

We propose an extension to Description Logics (DLs) with uncertainty which unifies and/or generalizes a number of existing frameworks for DLs with uncertainty. To this end, we first give a classification of these frameworks and identify the essential features as well as proper ties of the various combination functions allowed in the underlying uncer tainty formalisms they model. This also allows us express the semantics of the DL elements in a flexible manner. We illustrate how various DLs with uncertainty can be expressed in our generic framework.
