Electric Discharge Machining (EDM) is very important and prominent machining processamong all the newly developed non -traditional machining techniques. This process isextremely useful for “difficult to machine” conducting materials such as heat treated toolsteels, composites, super alloys, heat resistant steels, ceramics, carbides, etc. In thistechnique i.e. in EDM, the material removal of the electrode is achieved through highfrequency sparks between the tool and the work-piece immersed into the dielectric. TheMaterial Removal Rate (MRR), Tool Wear Rate (TWR) and surface roughness are some ofthe important performance parameter of EDM process. The objective of EDM is to get highMRR as well as achieving reasonably good surface quality of machined component. Themachining parameters that achieve the highest MRR strongly depend on the size of themachining surface i.e. Electrode used and work-piece surface. With upcoming worldwideimportant applications of Non-Conductive ceramics machining has become an importantissue which needs to be investigated in much detail. The Alumina (Al2O3), Glass and otheradvanced engineering ceramics are rapidly emerging class of engineering materialspossessing a wide range of remarkable properties i.e. high hardness, chemical stability,very low friction, unique electrical properties and these engineering ceramics posses highwear resistance which make them highly suitable for such engineering applications as jetengines and other aeronautical components, tools and dies and electronic sensors.

Available in a variety of styles, shapes and colors, quartz wall clocks make an affordable time-keeping option for any room in the home or office. Like any mechanical operation, however, they aren't exempt from the occasional need for repair, which can easily be done with a little knowledge and patience. The first and easiest problem to fix is restoring the clock's battery power, which is done by removing the battery from the back of the clock and replacing it with a fresh one. If the battery contact points – those little metal tabs inside the terminal – are corroded, you can usually clean them by first removing any loose corrosion with a moist paper towel before using a small bit of sandpaper to exfoliate any additional material from the contacts. In this guide “clock repair for beginners”, I will be teaching you all you need to know about repair and maintenance of different kinds of wrist watches from quartz, electrical, mechanical and antique clocks.

Power systems have two components of apparent power: active and reactive power. Both components are necessary for functioning of electrical systems. The active power is the average power absorbed by the resistive load. The reactive power is the measure of energy exchange between the source and reactive power of load. Energy storage devices do not dissipate or supply power, but exchange power with the rest of system. Active power is the one that is converted to other forms of energy in the load yet reactive power is only responsible for magnetizing purposes. Power factor is a ratio depicting how much of the power supplied is real. The reactive current contribute in the value of the overall magnitude of current in transmission lines causing unnecessarily high line currents and low power factor. Since a low power factor means higher amount of apparent power need to be supplied by the utility company, thus the company must also use bigger generators, large transformers and thicker transmission/distribution lines. This requires a higher capital expenditure and operational cost which usually result in the cost being passed to the consumer. In this research, we seek to identify the effects of a low power factor on Swaziland Electricity Company’s power supply system and recommend possible solutions to the problem. The results are useful in determining how to optimally deliver power to a load at a power factor that is reasonably close to unity, thus reducing the utility’s operational costs while increasing the quality of the service being supplied.

"In the early 19th century, as the Industrial Revolution was beginning to transform Europe, a majestic steamship known as the 'Lightning Bolt' embarked on its journey from the Old World to the shores of the United States. This luxurious vessel represented not only a means of transportation but also a symbol of opulence and comfort that attracted a select clientele. The voyage promised to be an unforgettable journey, a experience of luxury and comfort through the waters of the Atlantic Ocean. However, what no one could anticipate was that this voyage would become a labyrinth of secrets, intrigues, and mysteries that would shake the wealthy passengers and the crew of the Lightning Bolt. Amidst a gala dinner in the ship's opulent salon, a sudden electrical interruption plunged the diners into the deepest darkness. When the lights returned, a terrifying scene emerged: the murder of Alana, a wealthy millionaire, and the disappearance of a highly valuable necklace adorning her neck. Tragedy had struck amidst elegance and abundance. The arrival of the police marked the beginning of an intricate investigation in which a diverse group of suspects, including Alana herself, her friend Arlene, the waitress Ciara, the waiter Colin, and other notable characters such as detectives Callum and Aidan, the ship's manager Declan, and the affluent Ronan, would be subjected to scrutiny. Throughout this tale, hidden secrets within the bowels of the Lightning Bolt will be unveiled as the detectives struggle to uncover the murderer and solve the mystery of the missing necklace. Tensions will rise, conflicts will ignite, and an unexpected twist will lead to a deadly conclusion in a final confrontation filled with suspense." [more]

Professor Sir Charles Frederick Carter (15 August 1919 – 27 June 2002) was an academic known primarily for his role as the founding Vice-Chancellor of Lancaster University. Carter was born in Rugby to a father who was an electrical engineer and the developer of the Carter coefficient, and a mother who was an active member of the Society of Friends. He was educated at Rugby School and St John's College, Cambridge, where he read Mathematics and Economics and attained a First. In World War II Carter refused to fight, being a conscientious objector, and because he refused to accept any conditions for his exemption he spent three months in Strangeways Prison, Manchester. When released, he joined the Friends' Relief Service, where he met Janet Shea, whom he married in 1944. In 1945 he returned to Cambridge, where he became a lecturer in statistics and, from 1947, a fellow of Emmanuel College, Cambridge. He remained at Cambridge until 1952, when he took the Chair of Applied Economics at Queen's University, Belfast. Whilst in Northern Ireland he became a student of The Troubles, and concluded that a Protestant monopoly on power was unacceptable and could not be sustained. He also chaired the Northern Ireland Economic Development Council. In 1959 he moved to the Stanley Jevons chair in Manchester, remaining there for four years. As an economist he was a follower of G.L.S. Shackle, and was concerned about the impact of expectations in human decisions. In 1963 he became the founding Vice-Chancellor of the new University of Lancaster. He managed to admit the first 264 students in 1964, a year ahead of schedule, by utilising disused buildings as temporary accommodation and teaching facilities. Carter's vision was for Lancaster to be a university for the whole North West, commenting that the people of Lancashire thought of it as their university. He refused "discrimination on the grounds of race, colour, politics or any other thing" and established links with various Higher Education Colleges, thus pre-empting the drive for widening participation forty years later. His tenure at the University of Lancaster ended in 1979, the same year he was knighted. He retired to Seascale, Cumbria, and continued to work on projects he deemed to be worthwhile. [more]

Excerpt (intro words recited): "I might give you my name, yet it wouldn't be for real. Sincerely, I change them at my whim. Fifteen years ago I was initiated into the existence of House and Clan Tremere. A fascist, hermetical lodge of wizards [Erich Fromm, the anatomy of human destructiveness]. That is, of course, for the unknowing. I was ghouled by an undead vampire sorcerer, for my unique skills should have served this bloodline of vampires until I either qualified for the Embrace, or got killed. How did it come to be? I hardly know. Something I did, or perhaps something I am, attracted its attention. Please don't get me wrong, it was a step forward." Prose from a loudmouth in the world of darkness, back then the famous Vampire the Masquerade fancraze.

In the current study, an industrial product (electrical wire connector) have been casted in cold chamber die casting process using LM2 aluminium alloy to produce certain specimens to be assessed under the study for the determination of the responses ( mechanical properties such as impact strength, hardness and surface roughness). As cold chamber die casting is being popularly known for its efficient and accurate casting process which can process a broad range of castings with intricate shape easily, hence it requires a lot of study in controlling the process variables with optimum combination of process variables to produce defect free and sound casting. Therefore in the current study, the process variables such as pouring temperature (725oC, 750oC, 775oC), intensification pressure (170 kg/cm2, 180 kg/cm2, 190 kg/cm2), type of coating (oil+graphite coating, dycote+graphite coating and dycote coating) and type of cooling (air cooling, water cooling and oil cooling) have been varied at three levels and 9 different experiments have been designed using Taguchi array (L9 orthogonal array) to assess the effects of different combinations of process variables over the mechanical properties (impact strength, hardness and surface roughness). The study aims at selecting the optimum combination process variables on the basis of the responses resulted in the 9 experiments. The graphs for the responses (impact strength, hardness and surface roughness) against each process variables have been plotted and carefully observed to identify the significant process variable along with respective level of operation affecting the respective response. From the overall study, intensification pressure was concluded to be the most significant process variable with maximum contribution to the impact strength and surface finish. The micrograph images captured corresponding to the respective levels of intensification pressure (170 kg/cm2, 180 kg/cm2, 190 kg/cm2) revealed the presence of shrinkage porosity corresponding to lowest level of intensification pressure (170 kg/cm2) and with further increase in intensification pressure led to a decrease in the extent of presence of porosity. Dycote coating was considered as the most optimum coating with significant contribution to the hardness. Air cooling and oil cooling were equally significant process variables with equivalent contribution to the mechanical properties. [more]
