Improving Fibre Optics Transmission with Wave Length Division Multiplex through Routed-Switching Network
Get PDFThe Optics Fiber link is implemented to satisfy various types of networks, with a wide range of transmission capabilities and improved speed in signal delivery. The link carries multiple signals and for adequate transmission, multiplexing of signals, each signal component, is aggregated and transmitted over a common link which is regarded as multiplexing. The wavelength-routed network bridges the gap of the timeshare, which has retardation on speed and efficiency. The wavelength division multiplex (WDM) is a multiplexing technique designed to suit fiber optics and achieves speed demands, as against time-division multiplexing(TDM) for analog continuous signals (CT) and frequency division multiplexing(FDM) for discrete-time signals(DT). The synchronous optical network (SONNET) and synchronous digital hierarchy (SDH) and the Asynchronous transfer mode (ATM) create an inter-switching system using various matrix dimensions, of 2 X 2, 8 X 8 and other multiples to achieve a versatile routing switching technique. Wavelength division Multiplex and it’s a dense modification (DWDM); have greatly improved the quality and speed of signal transmission over all other techniques
City-wide Quality Assessment of Sandcrete Masonry Blocks Produced in Lagos, Ibadan and Abeokuta Metropolitan-cities in South-western Nigeria
Get PDFIn this research work, a total of nine thousand (9,000) numbers of Sandcrete masonry blocks and another total of nine thousand (9,000) numbers of Sandcrete masonry blocks were collected as Test-samples from three hundred (300) Sandcrete block-making factories, which are randomly sited in thirty (30) rapidly developing towns/localities located within three (3) highly-populated and state-capital metropolitan-cities—i.e. ‘Lagos’, ‘Ibadan’ and ‘Abeokuta’ in South-Western Nigeria. Thus, from the cumulative total number of eighteen thousand (18,000) Sandcrete block test-samples, each of the thirty (30) numbers of ‘block test-samples’ and each of the thirty (30) numbers of ‘block test-samples’ which were collected from each of the ten (10) Block-making factories per town/locality was subjected to two (2) critical quality-evaluation tests—i.e. Compressive-strength test [using a compression-testing machine] and Water absorption coefficient test [in accordance with standard established procedures and then, the mean values were computed and adopted as the representative/characteristic data for each Block-making factory. Consequently, the obtained results/data were then comparatively analyzed using the Standards Organization of Nigeria ‘SON’standard specified (recommended) values to empirically evaluate the Block-making/production quality of each of town/locality per city and of each city. Amongst other things, the comparative analysis of the obtained results/data showed that: while all of the tested Sandcrete masonry blocks produced in Lagos city and Ibadan city are classified as substandard—having failed to meet (fulfill) the standard requirements; just of the Sandcrete masonry blocks, and as much as of the Sandcrete masonry blocks produced in Abeokuta city are classified as standard—having successfully met (satisfied) the Standard requirements—thus, making them the most ideal for construction purposes

Review of Stoichiometric Technique for Better Performance of the Boiler
Get PDFThe combustion within the boiler burns fuel to create heat energy which then produces electrical power. The combustion of fuel is its reaction with oxygen available in the air. The amount of fuel that can be well burnt is limited by the quantity of oxygen. Once all the fuel is not burnt at all, some of it stays in the boiler and other quantity goes to the atmosphere. Most of the fuels used in the boiler are hydrocarbons which release hydrogen and carbon as residuals. It causes small efficiency and degradation of the air. It is needed to take the faction of air/fuel to the optimum value to reduce these problems. This paper provides different reviewed algorithms that control the combustion within the boiler and the role of environmental temperature. The author found that the separation of the oxygen from the air combined with the preheating both fuel and oxygen taking into account environmental temperature would provide better stoichiometric values, which improve the performance

Comparative Study on Mass loss by the Sun and Energy Available for Utilization between two Tropical Stations in Nigeria
Get PDFThe electromagnetic radiation emitted from the Sun is called solar radiation. Almost all life on Earth evolved with the Sun as a major influence. The rising and setting Sun defined the daily cycle we still respond to biologically. This study investigates theyearly, monthly and daily variation of mass loss by the Sun for two locations; Gusau and Calabar situated across the Sahelianand Coastal climatic zones of Nigeria using daily, monthly and yearly global solar radiation meteorological data obtained fromthe National Aeronautics and Space Administration (NASA) during the period of twenty two years (July 1983 – June 2005). Theenergy available for utilization based on the mass loss by the Sun for the two locations was also investigated. The fluctuations inthe results revealed that the mass loss by the Sun varies significantly from year to year, month to month and from day to day; thus, indicating that it is site dependent and strongly depends on the global solar radiation and solar activities in each of the locations. The highest yearly, monthly and daily mass losses by the Sun for Gusau are 6.3155 1017 kg y -1 in 1985, 5.5691 1016 kg m -1 in April and 2.3482 1015 kg d -1 on April 21, 1985 respectively and the lowest yearly, monthly and daily mass losses by the Sun are 5.6423 1017 kg y -1 in 1999, 4.2740 1016 kg m -1 in December and 1.3031 1015 kg d -1 on December 25, 1999 respectively. The highest yearly, monthly and daily mass losses by the Sun for Calabar are 4.6558 1017 kg y -1 in 1984, 4.6451 1016kg m -1 in February and 2.0252 1015 kg d -1 on February16, 1984 respectively and the lowest yearly, monthly and daily mass losses by the Sun are3.6806 1017 kg y-1 in 1983, 2.5346 1016 kg m-1 in August and 1.9546 1014 kg d-1 on August7, 1983 respectively. The results indicated that the solar energy available for utilization for Gusau are greater than that of Calabar and this is a reflection of the abundant amount of global solar radiation received on a horizontal surface for Gusau as compared to Calabar
