Speed of a Projectile Propelled by a Solenoid Student: Octavio Alonso Cuesta De La Rosa Consultant: Evan Simmers Supervising teacher: Kent Hogan Assessor: Write your aim, need or opportunity, with an explanation of why it was worth achieving: My aim was to calculate the velocity of a ferrous projectile propelled by a solenoid. Originally I planned to build my own coil gun and use it for testing, but as time grew shorter and hardly any progress was made on the project

________________ ____________ (Head of the department, ECE) (Assistant Professor) EXTERNAL EXAMINER ACKNOWLEDGEMENT The satisfaction and euphoria that accompany the successful completion of any task would be incomplete without the mentioning of the people whose constant guidance and encouragement made it possible. We take pleasure in presenting before you, our project

6 SIMULATION RESULTS: 6.1 Introduction to mat lab: Matlab is a high-performance language for technical computing. It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation. Typical uses include Math and computation Algorithm development Data acquisition Modeling, simulation, and prototyping Data analysis, exploration, and visualization Scientific and engineering graphics Application development

was connected in parallel to the coupling capacitors of 100nF. These capacitors helps the coils to improve coupling co-efficient. Fig 4 Receiving end In fig. 4, the AC signal from the coil is passed through a Cockroft Walton (CW) voltage multiplier. A CW multiplier generates a high DC voltage from a low voltage AC. Hence, it can rectify the received AC voltage, as well as, step up the relatively low voltage. This is a classic multistage diode/capacitor voltage multiplier, which is economically

4 Power supply: A device which supplies electrical energy to an output load is called a power supply. Conversion of one form of electrical power to another desired form and voltage, typically involving converting AC line voltage to a well-regulated lower-voltage DC for electronic devices. Low voltage, low power DC power supply units are commonly integrated with the devices they supply, such as computers and household electronics. 5V DC power should be supplied to PIC microcontroller which will be

switched- capacitor array, the comparator, and the digital circuits. Power analysis of the switched-capacitor array is based on the charging and discharging energy during A/D conversions. At the beginning of the conversion, the capacitors are reset to GND. In the first bit conversion, the bottom plate of the capacitor is switched to VREF , and VDAC is charged to 1/2 VREF . This switching energy is 8CVREF 2. At this moment, if VIN>VDAC, then the current capacitor is kept to VREF and next capacitor is switched

Time Operated Electrical Appliance Controlling Systems Awadallah Sulieman Rahama Balola Department of Electrical & Electronic Engineering. University of Alneelain, Khartoum, Sudan. Supervisor D. Dalia Mahmoud Abstract: Time operated electrical appliance controlling system is a reliable circuit that takes over the task of switch on/off the electrical devices with respect to time. This project replaces the Manual Switching. Most used devices at home are electrical light, electric fan, air conditioner
