Hypothetical project (Tokyo sky city) Introduction Tokyo sky city is a hypothetical architectural project of a super tall skyscraper with the height that of two third of a mile. It was proposed in year of 1989 by Takenaka Construction firm of Tokyo‚ during the height of Japanese asset price bubble. The main aim of the ambitious architects of the firm then was to change the world’s approach towards urban crowding and overpopulation in the megacities like Tokyo‚ Mexico city and others.

British grocery store chain Tesco has recently been forcing employees at its Dublin distribution center to wear armbands that measure their productivity. The armbands‚ officially known as Motorola arm-mounted terminals‚ keep track of how quickly and competently employees unload and scan goods in the warehouse and gives them a grade. The monitors can be turned off during lunch breaks‚ but anything else‚ including bathroom breaks and water breaks‚ reportedly lowers workers’ productivity score.

RC Circuits •In this presentation‚ circuits with multiple batteries‚ resistors and capacitors will be reduced to an equivalent system with a single battery‚ a single resistor‚ and a single capacitor. Kirchoff ’s laws will be stated‚ and used to find the currents in a circuit. In addition‚ the equation for the time-constant of an RC circuit will be derived. Ohm ’s Law When a battery is connected to a resistor‚ the battery will cause a current to flow through the resistor. The larger the voltage

Caring for Cooper City There are many factors affecting the health of this community. I believe lack of health education and access to health care are the primary problems. The problems of pinworms and anemia are most preventable with hygiene education and nutritional education. The high premature births and neonatal death rate can be addressed with pre-natal education and care. The ability for the mothers and care givers to access these services may be impaired because of lack of access to health

50 to 75 kilovolts‚ why not use them in drivers such as this one… Moreover‚ the simplicity of this circuit also adds a possibility of some simple audio modulation of the arc. So‚ let’s begin! The quasi-resonant topology But to say the least‚ the first driver I have built with this topology had an AC flyback and an input power supply rated just 60 watts. The result was a compact‚ short-circuit proof‚ high voltage “lab” supply with frequency control‚ some active cooling‚ audio modulation (singing

complete circuit. A complete circuit requires a battery‚ wires and a light bulb. 2. Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are different. Both series and parallel circuits must have all the components of a complete circuit in order to work. These two circuits differ in the way the electrons are able to flow. In a series circuit the electrons flow in one direction and along one path only while in a parallel circuit the electrons

electrons only travel at a person’s walking pace! Circuits: Electrical circuits are designed to take energy from a power supply (battery‚ generator‚ alternator‚ solar cell‚ thermocouple‚ fuel cell‚ . . .) and ultimately deliver the energy to an output (heater‚ light‚ motor‚ TV‚ computer monitor‚ speakers‚ . . .). In some cases the energy is the important part (heaters‚ motors) in other cases it is the information carried and manipulated by the circuit that is the useful output (telephone‚ cellular

The Incident One of the worst domestic terrorist attacks in United States history was the Oklahoma City bombing. The attack occurred on April 19‚ 1995 and the two assailants were Timothy McVeigh and Terry Nichols. The bombing killed 168 people and wounded 680 others‚ the blast from the bomb destroyed 324 buildings‚ causing an estimated $652 million dollars’ worth of damage‚ but the main building of the attack was the Alfred P. Murrah Federal Building. The two attackers were captured within an
