Abstract: Phase absence is a very common and severe problem in any industry‚ home or office. Many times one or two phases may not be live in three phase supply. Because of this‚ many times‚ some electrical appliances will be on in one room and OFF in another room. This creates a big disturbance to our routine work. This project is designed to check the availability of any live phase‚ and the load will be connected to the particular live phase only. Even a single phase is available‚ and then also

or decreasing temperature. We have worked with hot plates and thermometers in other labs before‚ so we know how to be safe. I wonder what a graph of the changing temperatures over time between the phases would look like. Hypothesis Based on prior learning‚ I predict that the graph of the water phase changes will not be one straight slope‚ but instead will plateau‚ or be flat‚ and then slope between the change of ice to water‚ plateau and slope once more between the change of water to steam‚ and

Tracking(locked) ABSTRACT We were assigned to build a phase locked loop frequency synthesiser. The purpose is to help students to gain experience in hardware construction‚ coordinated teamwork and project management. The design uses 74HC4046‚ a PLL integrated circuit (IC) made from CMOS technology A PLL is a closed loop frequency system that locks the phase of an output signal to an input reference signal. The term “lock” refers to a constant or zero phase difference between two signals. The signal from

Understanding Questions Directions: Answer the following questions in complete sentences. One to two sentences will not suffice. 1. Write down what your observations as you look at the ball at different positions in its orbit around your head. The ball goes thru the same phases that the moon would go through. The way I started would be the same as the full moon (the ball

racing ahead. The process of NPD is crucial within an organization. Products go through the stages of their lifecycle and will eventually have to be replaced There are seven phases of new product development. The approach of the three companies to NPD will be analyzed in relation to the NPD phases as discussed briefly below: Phase 1: Idea generation New product ideas have to come from somewhere. But where do organizations get their ideas for NPD? Some sources include: • Within the company i.e. employees

Every property is subject to potential environmental risks‚ the phase one environmental site assessment (ESA) can help determine whether a property may have been contaminated by current or previous activities. The purpose of the environmental assessment is to determine if there is a contamination on the property which may affect the environment or the people who are using the property. It is commonly required when there’s a transaction in the ownership of the property‚ when applying for a building

1 A Voltage-Controlled Oscillator (VCO) is a circuit that provides a varying output signal (typically of square-wave or triangular-wave form) whose frequency can be adjusted over a range controlled by a dc voltage. An example of a VCO is the 566 IC unit‚ which contains circuitry to generate both squarewave and triangular-wave signals whose frequency is set by an external resistor and capacitor and then varied by an applied dc voltage. Figure (1) shows that the 566 contains current sources to charge

Phase Change Lab Ha Min Noh Ms. D Chemistry February 6‚ 2016 Question How does time relate to the change in temperature of H2O as it changes phases from ice to water to gas? Hypothesis If the time which H2O stays on the hot plate increases‚ then the temperature of H2O will increase and the phases from ice to water to gas will change because the heat is a source of energy to change the physical states. Background Ice is a solid form of H2O and water is a liquid form of H2O. The gas form of H2O

3 Phases of Carbon Cycle Phase 1: Carbon fixation The Calvin cycle incorporates each CO2 molecule by attaching it to a five-carbon sugar named ribulose biophosphate (abbreviated RuBP). The enzyme that catalyzes this step is RuBP carboxylase‚ or rubisco. The product of the reaction is a six carbon intermediate so unstable that it immediately splits in half to form two molecules of 3-phoshpyglycerate (for each CO2) Phase 2: Reduction Each molecule of 3-phsophoglycerate receives an additional
