The exploitation of distributed energy resources and problems associated with islanded energy grids are important in optimizing sustainability of electricity supply, where microgrids play a major role in the decentralized and dispersed production. As defined, a microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a...
The present need for software organizations to seamlessly carryout software development results to significant high cost of electricity usage and emission of CO2 which contributes to climate changes. Therefore there is need for software practitioners to adopt sustainable practices in software development process. Sustainable practices can be adopted when software practitioners utilizes software which...
Cities are facing an increasing growth in population, resulting in, among other things, increasing quantities of waste being generated. Industrialization and economic growth has produced more amounts of waste, including hazardous and toxic wastes. Thus, every year, millions of tonnes of litter end up in municipal or industrial waste dumps, oceans, beaches, forests and elsewhere in nature. This paper...
It is well acknowledged that environment plays an important role in requirement derivation. However, at present the time-continuous properties of the environment are of little concern. Our previous work modeled the time-continuous environment by constructing a software environment ontology. This paper further presents an approach for deriving software requirements specification with time using software...
There is growing attention paid to the increasing in the global carbon dioxide production and to the subsequent issue of sustainability in ICT-related projects. But very few information and time has been spent right now for determining a set of related measures from sustainable processes. Moving from a new set of three sustainable processes in the SPICE (ISO/IEC 15504) format, this paper proposes...
With the increasingly security problems in networks and systems, the evolution of development models that underlie current tools and techniques is all that is required to produce a model of self-defense where all the components are self-protected. The great extension of current models recommends a reasonable transition fundamentally based on the family of standards ISO/IEC 31000, where the selection...
With the advancement of information technology resulting in the blurredness of industry boundaries, companies have tried to integrate product and service to fulfill customer requirements and create competitive advantage in the market. The key in convergence is software. To make convergence effective, three things need to be considered. This article discusses the role of software in convergence and...
Resource management information System is based on system theory, information theory and control theory, facing three major scientific issues that called population, resources and environment. It has received a wide range of applications, such as the scientific management of the resource data to support various types of resources and scientific research activities to meet national or regional comprehensive...
Automated subsystem for configuration of information environments (program agent) was researched and considered. Subsystem, relying on the existing hardware and software configuration and a desired information capacity, provides autoconfiguration of information environment.
This report discusses the merits and limitations of the two main choices of learning and teaching method which are the traditional learning (t-learning) and electronic learning (e-learning) methods. On the basis of this comparison and evaluation, the report suggests the blended learning (b-learning) method as an effective alternative approach for teaching and learning process. The term b-learning...
Self-adaptive systems aim at autonomously achieving their objectives in a dynamic environment, adapting their behavior to different circumstances. We claim that appropriate software engineering methodologies are needed to define and to model the information necessary for a system to perform autonomous diagnosis and decision making at runtime.In this short paper we focus on conceptual modeling for...
The role of software has expanded from simply assisting business activities to managing and controlling its process. To that extent, mismanaged software can have fatal impact on working systems. This emphasizes how important the quality of software is. The purpose of this paper is to suggest ways to improve software processes, and therefore focuses on software process improvement models. This study...
Young adults with severe disabilities and learning difficulties (SLD) have very limited access to appropriate learning resources. Their unique individual needs and requirements prevent them from accessing traditional methods of online learning, and resources tend not to be age appropriate. The majority of SLD learners has difficulty accessing a computer with standard peripherals such as a mouse and...
The paper presents our intermediate results in ontologizing a refined formal representation of environments, events, and happenings elaborated in PSI project. This ontology is used for agent-based modeling of engineering design systems and processes. Our formal approach is inspired by discrete event calculus (DEC). In difference to DEC based on discrete linear time representation, it uses fuzzy time...
This paper describes a SoSE environment designed to facilitate the problem-solving process of complex situations. Complex situations can be seen as the behavior of a system of systems that needs to be transformed to a desirable state. This is addressed by exploring the impact and implications of systems analysis and design within a social/group setting where many stakeholders with issues, concerns...
Sage is a free, open source mathematical software system written in Python with impressive capabilities. Python has the advantage that it's a modern, object-oriented language. SAGE Project introduced the software for algebra and geometry software system to considerable fanfare in the scientific computation field. As the name suggests, Sage is aimed at the mathematics user who wants to approach a mathematical...
