Source Code

The maintenance portion of the software lifecycle represents a major drain on most software company's resources. The transition from programmers to maintainers is high risk, since usually the maintainers have to learn the system from scratch before they can begin modifying it appropriately. This paper introduces a method for automatically extracting important traceability information from a C# software project's source code. Using this traceability information, maintainers (and programmers) are better able to evaluate the impacts their actions will have on the entire project.

Abstract Global software development is rapidly becoming the norm for technology companies. Previous qualitative research suggests that multi-site development may increase development cycle time. We use both survey data and data from the source code change management system to model the extent of delay in a multi-site software development organization, and explore several possible mechanisms for this delay. We also measure differences in same-site and cross-site communication patterns, and analyze the ...

A preoccupation with content and connectivity in bridging the digital divide obscures the role of information and communication technology in making different ways of knowing and other logics and experiences visible or invisible. How to deal with this diversity in information systems and what is the role of Free/Libre Open Source Software (FLOSS)? In a discussion of the Development Gateway,

Source code retrieval is of immense importance in the software engineering field. The complex tasks of retrieving and extracting information from source code documents is vital in the development cycle of the large software systems. The two main subtasks which result from these activities are code duplication prevention and plagiarism detection. In this paper, we propose a Mohamed Amine Ouddan, and Hassane Essafi source code retrieval system based on two-level fingerprint representation, respectively the structural and the semantic information within a source code. A sequence alignment technique is applied on these fingerprints in order to quantify the similarity between source code portions. The specific purpose of the system is to detect plagiarism and duplicated code between programs written in different programming languages belonging to the same class, such as C, Cµ, Java and CSharp. These four languages are supported by the actual version of the system which is designed such t...

In this paper, we present an efficient real-time implementation technique for Motion-JPEG2000 video compression and its reconstruction used for a real-time Airborne Video Telemetry System. we utilize Motion JPEG2000 and 256-channel PCM Encoder was used for source coding in the developed system. Especially, in multiplexing and demultiplexing PCM encoded data, we use the continuous bit-stream format of the PCM encoded data so that any de-commutator can use it directly, after demultiplexing. Experimental results show that our proposed technique is a practical and an efficient DSP solution.

New software security vulnerabilities are discovered on almost daily basis and it is vital to be able to identify and resolve them as early as possible. Fortunately, many software vulnerabilities are recurring or very similar, thus, one could effectively detect and fix a vulnerability in a system by consulting the similar vulnerabilities and fixes from other systems. In this paper, we propose, SecureSync, an automatic approach to detect and provide suggested resolutions for recurring software vulnerabilities on multiple systems ...

Abstract-We describe a sequential universal data compression procedure for binary tree sources that performs the “double mixture.” Using a context tree, this method weights in an ef-ficient recursive way the coding distributions corresponding to all bounded memory tree sources, and ...

Abstract. Invariance is a necessary feature of a visual system able to recognize real objects in all their possible appearance. It is also the processing step most problematic to understand in biological systems, and most difficult to simulate in computational models. This work investigates the possibility to achieve viewpoint invariance without adopting any explicit theorical solution to the problem, but simply by exposing a hierarchical architecture of self-organizing artificial cortical maps to series of images under various viewpoints. 1

ABSTRACT: A major problem in software maintenance is the lack of a well-documented source code in software applications. This has led to serious difficulties in software maintenance and evolution. In particular, for those developers who are faced with the task of fixing or modifying a piece of code they never even knew existed before.
