The Comoros is an archipelago in the Indian Ocean located Mozambique Channel between African continent and Madagascar. Geographically composed of four islands: Grande Comores, Anjouan, Mohéli Mayotte (under French administration). Apart from Mayotte, others three independent islands commonly known as Union are suffering energy stress since their independence year 1975 until nowadays. supplied d...

Acoustic communications using a direct-sequence spread spectrum modulation with a RAKE receiver was tested during the KauaiEx experiment (in Hawaii). The oceanography was measured along the communications path during this test, so that the propagation of the communications transmissions could be subsequently modeled. Such simultaneous measurements provide a continuous picture of how the ocean w...

The risk and losses associated with the wind-induced failure of existing steel lattice telecommunication towers are assessed for a number upgrade/replace/redesign schemes. Specifically, performance-based wind engineering framework is employed assessing typical tower topology used by EU network operators over four different cases: conventional design, its corroded version after 60 years, strengt...

Radiofrequency electromagnetic field=radiation (RFR) covers a large segment of the electromagnetic spectrum and falls within the nonionizing bands. Its frequency ranges between 3KHz and 300GHz. Cellular phones, wireless transmission towers for radio, TV, and telecommunication, radar and many other applications emit RFR. Different frequencies of RFR are used in different applications. For exampl...

The purpose of this study is to develop a master plan for mapping joint cellular telecommunication BTS towers in accordance with the Regulation Minister Communication and Information Number : 02/Per/M.Kominfo/03/2008 regarding use together. method used collect process data analyze distribution zone using MapInfo software. collection was an existing population which calculating find need future ...

In this paper we summarize the research activities at the Instituto de Telecomunicações--Pólo de Aveiro and University of Aveiro, in the field of fiber Bragg grating based sensors and their applications in dynamic measurements for Structural Health Monitoring of slender structures such as towers. In this work we describe the implementation of an optical biaxial accelerometer based on fiber Brag...

Through this paper, our focus was to utilize information collected from telecommunication providers related to the usage of roads by different vehicles. Complexities within collected data were a major requirement to be resolved and corrected through the definition of algorithms that provide cleansed data that can be utilized within the analysis of information. The primary focus of this paper is...

The power management of ICT systems, that is, data processing (Dp) and telecommunication (Tlc) systems, is becoming a relevant problem in economical terms. Dp systems totalize millions of servers and associated subsystems (processors, monitors, storage devices, etc.) all over the world that need to be electrically powered. Dp systems are also used in the government of Tlc systems, which, beside...
