In this paper we propose new model to see how graph technologies can be used to analyses Call Detail Records (CDR) in order to find potential criminals. We face the challenging task of automatically deriving meaningful information from the available data, by using an unsupervised procedure of data analysis and without including in the model any a p...

In this study of power management, the hybrid system consists of a 1.2kW Nexa PEM fuel cell, three 12V batteries, DC/DC converters to power Unmanned Aerial Vehicles (UAV). The control strategy is control the power between the FC and the battery by using PID controller is based on the following principle: The PEMFC is the main power supply for the e...

Dust and sand storms attenuation is one of the main problem in usage of microwave bands for terrestrial and DB satellite at desert areas. This paper present and enforce a mathematical version to are expecting the microwave sign attenuation because of dust and sand storm withinside city of Sabha. The foremost enter parameters for the version are vis...

The high price of incoming international calls is a common method of subsidizing telephony infrastructure in the developing world. Accordingly, international tele- phone system interconnects are regulated to ensure call quality and accurate billing. High call tariffs create a strong incentive to evade such interconnects and deliver costly internati...

The link communication between satellite and the Earth Station is exposed to a lot of impairments such as noise, rain and atmospheric attenuations. The successful implementation of satellite communications need to the efficient system design to ensure robust air links for the communications signals. However, the quality of satellite signals are sub...

WiMAX is a wireless access system that offers fixed, nomadic, portable and mobile wireless broadband services. The problem of dimensioning large scale broadband wireless systems is a vital confront in radio network planning. A perfect knowledge of path loss performance is an essential requirement for primary deployment of wireless network and cell...

Signal attenuation caused by dust and sand storms is one of the major problems in utilization of microwave bands for terrestrial and space communication especially at desert and semi desert area, such as South of Libya. In this paper presented a model based on estimated visibility and volume of dust particulars and developed to predict the microwav...

Every year Libyan treasury, Libyan central bank and other commercial banks lose millions of dinars to fraud and scams. There are many different types of fraud and scams, such as duplicative jobs and Fraudulent loans. It is important for the government and the financial institutions to be able to recognize fraud and scams before they are targeted. T...

In mobile networks, performance evaluation is an important part in modeling and designing effective schemes to utilize the limited resource. In the past, performance evaluation was carried out either under restricted assumption on some time variables such as exponential assumption or via simulations. In This paper discusses different schemes for pr...

In this paper we are considering the possibility to use AdHoc-networks with the latest protocol from (IEEE 802.11) family to build big private network can be use everywhere in the city to share everything (video, voice, internet connection and data), network give us free movement as mobile networks, strong security as wire LAN and speed up to 100Mb...

The LTE network transmission issue of telephone traffic is of particular importance. LTE standard is designed for the transmission of packet traffic, so it does not implement the service circuit-switched telephony. But namely voice traffic gives to mobile operators the most of income. In this paper proposed Comparative analysis of solutions of voic...

This paper is intended to be an introduction into the issues involved with delivering IPTV over WiMAX networks. The use of WiMAX Networks can provide service not only for fixed but also for mobile subscribers , However, there are still issues concerning bandwidth, codec selection, QoS and payload on WiMAX , where passing IPTV traffic relates to the...

Spatio-Temporal Role-based access control (STRBAC) has been acknowledged as an effective mechanism for specifying access control policies for cyber systems. However, it is not yet clear how a STR-BAC model can be used for specifying access control policies for physical systems. In this paper, we propose a Spatio-Temporal Role Based Access Control (...

Sources of electrical oscillations and frequency modulators (FM) with high stability of the average frequency are required for any data transmission systems, radar and radio navigators. Stability determine the most important parameters of modern electronics-the accuracy of action, speed and bandwidth, noise immunity and stealth action. The aim of t...

Mobile IPv6 with fast Handover enables a Mobile Node (MN) to quickly detect at the IP layer that it has moved to a new subnet by receiving link-related information from the link-layer; furthermore it gathers anticipative information about the new Access Point (AP) and the associated subnet prefix when the MN is still connected to the previous Corre...

In this paper we propose to replace the circuit inductance for inductive dynamic negatron (IDN).
