The Distributed Computing Environment (DCE) software of the Open Software Foundation o ers solutions for security problems and for shared le management in heterogeneous computer networks. It allows distributed programming by remote procedure calls and parallel programming by threads. Distributed shared memory in a computer network pretends a globally shared address space among networked compute...

This paper presents the concept of an environment for distributed mathematical education based on the computer algebra system Mathematica c. Mathematica is a \system for doing mathematics by computer" which combines a computational engine with powerful presentation and visualization facilities based on the concept of notebooks (multimedia hypertext documents). The system has gained large popula...

sorting and classification of agricultural products by machine vision system reduce costs and increase quality and accuracy. this research was performed to develop an algorithm and machine vision system for separating dirty and defects eggs and classifying by volume and weight. this machine installed on transport line egg in agriculture included a digital camera, computer and mechanical device ...

This study aimed to investigate the impact of the hospital information system (HIS) on nurses' satisfaction in Iranian public hospitals and to examine the moderating effect of computer literacy. The study population consisted of nurses working in public hospitals in Iran. A sample of 385 Iranian public hospitals was surveyed and a total of 1912 questionnaires were collected over 9 months. The a...

A distributed system is a collection of autonomous computers linked by a computer network that appear to the users of the system as a single computer. In a large distributed system, security is provided by the use of cryptographic techniques such as key generation. It has a major role in solving Computational problems. Data outsourcing in a distributed system represents that a data owner outsou...

Supervisory Distributed Computer Control Systems help the operator to run the process by putting control and monitoring functionality at his or her disposal. These systems support the Human Machine Interface, Message Handling, Archiving, Hardware Diagnostics and they execute control functions automatically. With respect to these requirements, the functionality of supervisory distributed control...

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...

A distributed operating system is one that looks to its user like an ordinary centralized operating system, but runs on multiple, independent nodes. A distributed operating system should: control resource allocation to allow their use in the most effective way; provide the user with a convenient virtual computer that serves as a high-level programming environment; hide the distribution of the r...

There is still no widely accepted system to exploit the capabilities offered by the tremendously grown number of computers connected to the Internet or to large intranets. Missing abstractions as well as deficiencies of software development prevent the effective use of more than two computers by standard applications. The architecture that is presented in this report overcomes these problems by...
