We assume that the 3000 household is in Pooraka a suburb of Adelaide where the maximum houses are occupied by working class mid-age parents with teenage children. For Light User we assume the percentage of users to be around 25% who use the internet on necessity and to gather information. For Regular User we assume the percentage of users to be around 45% as the area has more households in the mid age group and their usage is to be updated with the latest buzz in the world finance and keep a ...
Arc welding is a process of the fusion welding processes which contains:- 1 - Arc - welding processes (non consumable electrodes) Gas tungsten - arc welding Plasma - arc welding Atomic - hydrogen welding 2 - Arc - welding processes (consumable electrodes) Shielded metal arc welding Submerged - arc welding Gas metal arc welding Flux cored arc welding Electro gas welding Electro slag welding 3 - Electron - beam welding 4 - Laser - beam welding The main concept of fusion welding is the partial m...
Abstract: The common high power wind turbine erected, generally has a heavy gearbox attached to the turbine rotor to a synchronous generator. It also contains a cabinet full of electronics which convert the generator output to grid-compatible power. The normal nacelle itself has to be elevated some 50 stories off the ground, so major maintenance issues are involved while dealing with the removal and replacement of components. At the least, technicians must make the 50-story climb periodically...
1. Introduction It has become apparent that the severe underutilization of the electromagnetic spectrum [7] calls for alternative and novel solutions in the utilization of the radio resource. The process of statistically gathering and interpreting data to provide spectrum management information is called Spectrum Sensing. These types of activities require high processing power and reconfigurable hardware platforms. An optimum solution is Software Defined Radio (SDR) Platforms. 1.1. Spectrum S...
In construction area, the accurate and complete of the cost estimation is the key to success profitability of the construction project. Cost estimation is utilized as one of the main implements of successful cost management for the project. A good estimator should understand in the construction materials, the method and system of the construction. This is very important for them to do the estimating as well as the labour and equipment required to complete the entire mission in their correct c...
Good quality high voltage (HV) insulators help in achieving high performance of overhead Transmission lines (OHL). They isolate HV power lines from the tower and support the lines by maintaining them connected to the tower. HV outdoor insulators are facing many challenges in their life-time. One of the problems is the corona discharge that results from the high electric field stress at both ends of the insulator regardless of the type of the insulator (ceramic, non-ceramic, or glass). The ele...
The SGS GmbH (Societe Generale Surveillance) is a worldwide company for product testing, certification and verification. The service field includes agriculture, automotive, consumer testing, environmental, industrial, life science, minerals and chemicals. The SGS SOLAR TESTHOUSE, as a part of SGS GmbH was established in the summer of 2009 in Saxony, a region where many of the german solar technology manufacturers are located. The business field of the Solar Test House is Photovoltaic (PV) mod...
Introduction In computational devices, for example computers and digital signal processing elements, a fast parallel binary adder is essential. In many cases, to obtain sum and carry within one clock cycle is important. In the case of a pipeline, the latency of the pipeline is often expected to be as small as possible. The speed limitation of a parallel binary adder comes from its carry propagation delay. The maximum carry propagation delay is the delay of its overflow carry. In a ripple carr...
Steel, the most common metal alloy in the world, consists of iron and varying amounts of carbon. The evidences of iron and carbon since ancient times, is followed by that of steel. Ancient Steel and Crucible Steels The earliest evidence of the production of steel comes from the Indian Subcontinent in 300 BC. Later in the 5th century Chinese prepared Wootz steel, the first crucible steels, and widely exported and traded throughout ancient Europe, China, the Arab world, and it was popularly kno...
Currently biofuel has attracted a lot of interests because of the energy crisis. DMF, known as 2,5-Dimethylfruan, came into researchers' eyes when its improved production methods were published in Nature and Science in 2007. It can become a possible alternative to gasoline for its high energy density. The aims of this project are to do some study on DMF and make a comparison between DMF, ethanol and gasoline of their various properties in different tests. DMF (2,5-Dimethylfuran, liquid state ...
