enterprise resource planning (erp) has become the most strategic tool for an organization to employ. a leading erp solution is sap®. it has been employed by organizations to enable them to collaborate on different projects and to integrate all aspects of operations. just as organizations have adopted erp solutions, they employed quality initiatives that are designed to help organizations maximi...

Hash functions are often expected to provide security across applications, even if there is no formal backing for these expectations. For example SHA-1 is used variously as a collision-resistant hash function and as a real-world instantiation of a random oracle; recent attacks make either use less palatable. Better security would be provided by provable collision-resistance (resting on some und...

Traditional Intrusion Detection Systems (IDSs) mostly work off-line, without any direct runtime interaction or coordination with the applications (and with other IDSs) that they aim to protect. Including intrusion detection and response in the repertoire of an adaptive application extends its range of adaptivity and increases its chances for survival. In this paper we show how intrusion detecti...

In the industrial engineering community, it’s a well-known adage that focusing on process can help achieve better results. In this second of a series of papers, we’ll focus on the process of simulation testing and outline how improving your testing process can lead to better results for your projects. We’ll consider model building as a software development exercise, and discuss how best practic...

Web applications present important characteristics that must be properly addressed by software engineering methods, processes and techniques. In most cases, Web systems have to be delivered complying with severe time constraints due to its strategic nature for the client’s business. In this work we describe an agile process for Web-based application development, XWebProcess, which is based on E...

Small software firms that involved with developing web application are lacked of well defined development process. Many development methods have been proposed for developing web application in these firms. However, these methods have some limitations. This paper aims to identify the agile development methods that are suitable for small development teams and determine the enhancements needed to ...

The process of application evolution in the Web poses a tremendous challenge for Web Engineering. Changing requirements demand solutions providing flexibility beyond mere adaptation on the surface. The shift towards agile systems results in advantages noticeable during the whole application lifecycle. By enabling a reconfigurable composition of the overall system, a reduction of development and...

The intelligence analysis task of anticipating crises and providing decision makers with reasonable (supportable, explainable) possible futures is extremely difficult. To perform this task, a team of analysts must consider the political, economic, and military aspects of national governments and non-governmental organizations. This paper describes an agent-based simulation framework, the Advanc...

Background The development of software has gone from more strict plandriven projects to involve more human interaction and communication due to approaches like agile software development. With the realization of the importance of psychological aspect comes the possibility of learning from other more established research fields instead of reinventing the wheel. Objective In the field of work and...
