Abstract: In each stage of any satellite design cycle, it is required to have test system that verifies the operational functions of each satellite subsystem and the integration operation among the satellite subsystems. Usually, these test systems consist of many hardware’s and these hardware’s are very complicated and occupied large space. The first Egyptian satellite, Egypt Sat-1, has a test center; a place where the satellite integration test sequences are carried out. This center consists of complicated hardware. In this paper a new trend, using LabView tool with National Instrument (NI) chassis, is used to build a satellite test center (STC) prototype that reduce the cost, complexity and occupied area of the STC. So the new trend tests the ability to replace the Egypt Sat-1 test center. The results of this paper shows that the quality of the new trend compared to the existed Egypt Sat-1 test center.

Abstract: A number of security mechanisms are available to protect data such as digital signature, audits log, encryption, refining etc. however they completely not able to stop malevolent attacks. Hackers and attackers continuously try to exploit security which can be easily pushed through loopholes that are available at users end. The core reasons for such problem are mainly generated by terrible software requirements which are implemented without proper analysis of risks and threats. In order to reduce vulnerabilities security requirements standards, policies are tightly bound and used right from the beginning of software development. The major purpose of security standards and policy is to ensure that the data is always available at random in order to support security requirements against identified risks. The focus on this paper is to propose a model to quantify availability (MQAR) by using multiple regression technique at requirement phase. To rationalize the model statistical data is used to validate assess availability at requirement level and the significance of this study concludes that the calculated data is highly acceptable.

Abstract: The intent of this paper is to define a common case study for the domain-specific modeling research community. The domain of the case study is oil and gas pipeline design management systems, i.e., systems that help in identifying, handling, and controlling a pipeline design task by coordinating the communication between all component models and dimensions involved in handling the design, by allocating and managing resources, and by providing access to relevant design-related information to domain experts. This document contains general informal requirements for a pipeline design management systems (PDMSs), a feature model for the PDMS product line, and a domain model for the PDMS, as well as an informal physical pipeline model of the PDMS. Domain specific modeling researchers who want to demonstrate the power of their technique can hence apply the approach in other related areas at the most appropriate level of abstraction in the domain of pipeline engineering.
