1.Zero voltage regulation in a transformer occurs at :
(A)zero p.f. lead 
(B)unity p.f.
(C )leading p.f.
(D)lagging p.f.

2.A parallel plate capacitor has 15 p.F capacitance. If the linear dimensions of the plate are doubled and the distance between the plates are also doubled, then new value of capacitance would be :

BUILT IN SELF TEST FOR A CMOS ALU

Abstract:- A technique is proposed for implementing BIST (built-in self-test) in a CMOS arithmetic and logic unit (ALU). The approach covers single stuck-open faults and all functional faults that do not induce memory effects. The specific fault set covered by the test includes: (1) all single stuck-open faults on n and p transistors anywhere in the ALU (F1 faults); and (2) all functional faults that affect any single-bit slice of the (F2 faults), a functional fault being any fault that changes one combinati ....etc

ABSTRACT



Because of high requirements in power, efficiency, installation space and weight, the design of electrical machines for hybrid electrical vehicles is a particular challenge. This seminar describes a comparative study allowing the selection of the most appropriate electric-propulsion system for a parallel hybrid electric vehicle (HEV). This seminar is based on an exhaustive review of the state of the art and on an effective comparison of the performances of the four main electric propulsion systems, namely the d ....etc

TEST PLATFORM FOR SECURE WIRELESS COMMUNICATION USING XTEA

Abstract:- In this paper we present a new methodology for the integration of security provisions into protocols for wireless sensor networks. There is an ever-growing demand for security in communications in general. As wireless sensor networks (WSN) face real-world applications the authenticity of the retrieved data has to be guaranteed. To facilitate integration of security provisions into WSNs the platform TAP-SNS (Testing Algorithms and Protocols for Sensor Network Security) enab ....etc

The vibration load subjected to many products is the combination of several random processes corresponding to different application conditions, such as the various field road load inputs for automotive components. Sometimes the input loads are the combination of random and sinusoidal vibration. Due to the convenience of test setup and monitoring, the sinusoidal vibration sweep tests are often used for product durability validation by many automotive and consumer product manufacturers. It is therefore important to correctly correlate the sweep ....etc

Abstract Test card for color TV is a widely used method to evaluate the quality of a TV set directly. We have made a test signal generator (which can also generate synchronizing (abbreviated to sync hereafter) signals) mainly based on microprocessor Z-80. Taking the advantage of microprocessor programming, combining with the technique of microprocessor, digital circuits and analogue devices, we use software as far as possible to generate signals directly or to simplify the controlling circuits. Those signals, such as composite sync signal, bla ....etc
