the goal of this study was to investigate the effect of using computer conceptual maps­, compared with  usual way of drawing them by pencil and paper­, in increasing learning, recalling and educational progress motivation in geology course among high school students. the study was conducted in semi experimental method in which students of 3 classes were classified in 3 groups. (group 1: common ...

Today we collect data from different size of data, different locations and different type with a large scale in each site. Current computer server systems cannot process and collect these big data. For this issue, distributed computing system proposed in the literature. Supercomputers are changed to distribute computing, such as cloud computing systems. Software engineering is a part of each so...

There can surely be no doubt that appropriate, automated design techniques are essential for the success of any complex computer based systems. No computer system can succeed unless the complexity is well managed. The techniques cited in the brief are fundamental for the management of complexity and the development of computer based systems. My position is that automated system composition is i...

The possibility of building self-aware software fascinated computer scientist since the beginning of computer science. Research in AI, and in particular on software agents, agent system, computational reflection and reflective software delivered interesting results which moved towards the development of software systems with features of self-awareness. However, these approaches have not so far ...

BACKGROUND Modern chemistry laboratories operate with a wide range of software applications under different operating systems, such as Windows, LINUX or Mac OS X. Instead of installing software on different computers it is possible to install those applications on a single computer using Virtual Machine software. Software platform virtualization allows a single guest operating system to execute...

The Architecture Analysis & Design Language, (AADL), Society of Automotive Engineers (SAE), AS5506, was developed to support quantitative analysis of the runtime architecture of the embedded software system in computer systems with multiple critical operational properties, such as responsiveness, safety-criticality, security, and reliability by allowing a model of the system to be annotated wit...

Background: Modern chemistry laboratories operate with a wide range of software applications under different operating systems, such as Windows, LINUX or Mac OS X. Instead of installing software on different computers it is possible to install those applications on a single computer using Virtual Machine software. Software platform virtualization allows a single guest operating system to execut...

T-Engine is a standard architecture for next generation real-time embedded systems for ubiquitous computing to improve software productivity of these systems. This paper introduces the basic design philosophy of T-Engine, and overview of its standard hardware and software specifications. By now, several computer vendors have released more than ten hardware systems based on the T-Engine specific...

This paper outlines present and future directions for software in a Computer Integrated Manufacturing (CIM) environment. The three major CIM components -production management, data management, and communications management -are described in terms of software available today and future software based on emerging international standards. Key standards efforts such as product data exchange, open s...

The main thesis of this paper is that intricate nature of software systems and computer education systems can, and in our opinion should, be represented by graph models. Graphs are used in computer science and computer education almost everywhere, since graph is a very natural way of explaining complex situations on an
