long-and short-stroke actuator into one actuator system. Since most long-stroke movements are in a plane‚ this can be done by a contactless planar actuator. The topology proposed and tested in this paper provides long-stroke contact less energy transfer (CET) in a plane with only small changes in power transfer capability. 2.DESCRIPTION ACTUATOR Actuator is a mechanical device used for moving or controlling a mechanism or system. It converts electrical signals into motion.

Janet Mortensen‚ senior vice president of project finance at Midland Energy Resources‚ is in the process of preparing her annual cost of capital estimates for Midland and each of its three divisions (oil and gas exploration and production (E&P)‚ refining and marketing (R&M)‚ and petrochemicals). These estimates are used in many analyses within Midland‚ including capital budgeting decisions‚ financial accounting‚ performance appraisals‚ M&A proposals‚ and stock repurchase decisions.

Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient‚ hazardous‚ or impossible. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods under consideration include electromagnetic radiation in the form of microwaves or lasers

Experiment 4.5 Measuring the energy content of a “Dorito” and Popcorn. Using the method as described on page 46 of the textbook‚ measure the energy content of a Dorito and a “Popped” corn kernel. Aim: 1. Compare your results of each food and determine which will give the greatest energy per gram. 2. How much of each food would you need to boil 250mL of water? Hypothesis: (Before you begin‚ what do you think will be the conclusion.) As the Dorito is heated‚ it will release much more heat

Geothermal energy vs coal powered energy‚ what say you? Geothermal energy is a renewable source of energy generated and stored in the Earth. Coal powered energy is a source of energy produced from the natural resources of the Earth. Geothermal energy and coal powered both have many uses especially in generating electricity. In this field‚ they are similar as electrical energy is generated in a similar concept. Heat from the Earth’s crust and heat produced during the burning of coals are both used

Energy is needed by the body to stay alive‚ grow‚ keep warm and move around. Energy is provided by food and drink. It comes from the fat‚ carbohydrate‚ protein and alcohol the diet contains. Energy requirements vary from one individual to the next‚ depending on factors such as age‚ sex‚ body composition and physical activity level. Energy expenditure is the sum of the basal metabolic rate (the amount of energy expended while at complete rest)‚ the thermic effect of food (TEF‚ the energy required

Nuclear power uses unstable elements like uranium. Uranium is constantly going through a process called nuclear decay‚ which means the atom is splitting apart over a period of time‚ measured in half-lives. This is why it is the element of choice for nuclear power plants. Uranium is special because it can go through what is called induced fission. Induced fission is when a free neutron is fired at an atom (like uranium). The atom will absorb the neutron‚ and immediately becomes unstable and splits

SCH4U0 The Energy of Physical‚ Chemical‚ & Nuclear Processes The study of energy and energy transfer is known as thermodynamics. When this study of energy transfer is specific to energy involved in chemical reactions it is called thermochemistry. Studying Energy Changes The Law of Conservation of Energy states that the total energy of the universe is constant. (Energy can neither be created nor destroyed.

The Seven Habits of Highly Effective People Restoring The Character Ethic By Stephen R. Covey While I was reading ‘The 7 habits of highly effective people’ by Stephen R. Convey‚ many things were running through my mind. Stephen R. Convey’s words encourages us to live our life by some specific “principles” which can represent our overall effectiveness as a human in individual or social context. This book helps us to know “ How our habits can affect our character” and “ How our character
