Modeling, Specification & Evaluation Language (MOSEL), tool used for the performance and reliability modeling of communication systems, computers, and manufacturing systems, once the system is specified using this language. The modeling language is part of the evaluation environment. Once the system is specified using the language, the evaluation environment takes place by executing the performance analyses of the model, and calculating the steady state probabilities . After this stage, results can be collected in the result file or in graphics mode using the Intermediate Graphical Language (IGL), where the aim of this paper is to give an overview of mosel and to show a real example under windows platform.

Abstract Electric insulators are one of the main parts of over head Transmission lines, they must meet two requirements, first is the electric insulation for the conductors, and the second is to provide mechanical support for the over head lines. Insulators are subjected to various electric stresses of different origin such as operating voltages and an electric stroke waves due to Lightning storms. Therefore the insulators must perform well under all weather and environment conditions. In addition some times degradation occurs in the insulators performance due to accumulation of different types of pollutions on its surfaces. This project deals with two samples of silicone rubber insulators Have been exposed to the natural pollution for 6 years in continuously energized line working in Libyan transmission network. The test line is connecting between Khomes power station to Khomes switching substation it is 8.5 km long, the site is considered to be the most polluted site in Libya .Several tests have been done on this type of insulators to the effect of Libyan Environment on these insulators to decide if this insulator is suitable for working in the Libyan electrical grid.

The introduction of new services with different bandwidth requirements, e.g., data and multimedia, to cellular mobile radio networks makes many of the traditional mechanisms unusable or less efficient. The call admission control and the handover handling are the most sensitive issues to this extension. The performance of all services including the traditional voice and the new services can be dramatically effected if no appropriate schemes are used. In this research work, a new call admission and handover handling schemes for a cellular mobile network that offers two service types: voice and data is proposed. The data connections are assumed to be transmitted at different data rates, which are an integer multiple to that of one traffic channels, which are full speed(Cd1) & reduced peed(Cd2). In order to reduce the handover failure probability of data connections, the data mobile terminals (MT) are assumed to have the capability of transmitting at two different data rates. If the handover request can not be satisfied by the base station of the destination cell due to unavailable free traffic channels, the data mobile terminals tries with a lower data rate. The handover fails if the network is incapable on providing the minimum data rate at which the mobile terminal can transmit. The reduced data connection or data rate can be speeded up to full data rate or full speed as soon as enough bandwidth is available. The effect of different traffic and configuration parameters on the performance of the different models for two cell model with equal input traffic intensity, two cell model with different input traffic intensity, and two cell model with equal input traffic intensity considering the congestion rate for the highway model are studied as the models of this research. These models are built using MOSEL language (Modeling Specification and Evaluation Language). The results of investigating the mentioned models showed the effect of the handover, and speed of data on these different models.
