The construction of libraries of reusable software components is the standard software engineering solution for improving software development productivity and quality. By encapsulating usable functionality in software components (e.g. subroutines, object classes), and then reusing those components, software of greater functionality can be developed in less time, with some assurance that the ov...

introduction: direct and rapid access to information is one of the main necessities of the users in new technological world. nowadays, information users, particularly medical information in which rapid access is of necessity, do not have enough time to search and access to information. therefore, the present study aimed to determine strategies to access required information as soon as possible....

a watershed management program is usually based on the results of watershed modeling. accurate modeling results are decided by the appropriate parameters and input data. precipitation is the most important input for watershed modeling. precipitation characteristics usually exhibit significant spatial variation, even within small watersheds. therefore, properly describing the spatial variation o...

In this article some questions of testing of infrastructural Grid software on the standard compliance are discussed. Nowadays Grid-systems are one of the first-priority areas in computer science. The primary task is an effective usage of their advantages that is inseparably connected with the problem of software portability in Grid-systems. One of the simplest solutions of such problem is a dev...

This paper focuses on the requirements for face images to be used in Machine Readable Travel Documents, defined in the ISO/IEC 19794-5 standard. In particular an evaluation framework is proposed for testing software able to automatically verify the compliance of an image to the standard. The results obtained for thee commercial software are reported and compared.

Software systems are evolving by adding new functions and modifying existing functions over time. Through the evolution, the structure of software is becoming more complex and so the understandability and maintainability of software systems is deteriorating day by day. These are not only important but one of the most expensive activities in software development. Refactoring has often been appli...

Designing a software system’s architecture properly is one of the most important tasks of any software engineering project. Nevertheless there exists no common definition of the term “software architecture” and no standard software architecture description language (ADL). This paper discusses whether the standard OO modeling language UML is a standard ADL, explains some deficiencies if used for...

MIME (Mime Is Manual Expression) is a computationally efficient computer vision system for recognizing hand gestures. The system is intended to replace the mouse interface on a standard personal computer to control application software in a more intuitive manner. The system is implemented in C code with no hardware-acceleration and tracks hand motion at 30 fps on a standard PC. Using a simple t...

Context: Many people and organisations rely upon software safety and security standards to provide confidence in software intensive systems. For example, people rely upon the Common Criteria for Information Technology Security Evaluation to establish justified and sufficient confidence that an evaluated information technology product’s contributions to security threats and threat management are...

BACKGROUND The standardization of images used in Medicine in 1993 was performed using the DICOM (Digital Imaging and Communications in Medicine) standard. Several tests use this standard and it is increasingly necessary to design software applications capable of handling this type of image; however, these software applications are not usually free and open-source, and this fact hinders their ad...
