Short message service (SMS) is a globally accepted wireless service that enables the transmission of alphanumeric messages between mobile subscribers and external systems such as electronic mail, paging, and voice mail systems. The benefits of SMS to subscribers center around convenience, flexibility, and seamless integration of messaging services and data access. From this perspective, the benefit is to be able to use the handset as an extension of the computer. SMS also eliminates the need for separate devices for messaging, as se ....etc

Short Range Personal Radar
INTRODUCTION:
The idea to create a type of close proximity radar system came from a student in one of my classes. We went ahead and decided to streamline the idea into the course as one of the projects we'd build. After a week or two of prep time we finally agreed on the project setup & parts that we'd use. This is not meant to be an advanced project, thusly the difficulty is set at medium. Below is an example of what short range personal radar could be used for. It's meant to be a bit comical ....etc

Efficient Node Admission and Certificateless Secure Communication in Short-Lived MANETs

Decentralized node admission is an essential and fundamental security service in mobile ad hoc networks (MANETs).It is needed to securely cope with dynamic membership and topology as well as to bootstrap other important security primitives (such as key management) and services (such as secure routing) without the assistance of any centralized trusted authority.An ideal admission technique must involve minimal interaction among MANET nodes, since connectiv ....etc

Tomographic imaging of electrically large objects in 2-D and 3-D environments using ultra-wideband (UWB) sensor arrays is described. Object cross-section electric properties is the most difficult part to model.Different industrial, medical, and security applications use microwave signals to penetrate and sense light opaque materials with reasonable spatial resolution.Increased level of spatial resolution and materialelectrical parameter measurement accuracy of Wideband signals, such as those produced with ultra-wideband (UWB) systems makes it ....etc

Abstract

This paper reviews some of the existing studies on one-to-twenty four hour load forecasting algorithms, and presents an expert system based algorithm as an alternative. The logical and syntactical relationships between weather and load, and the prevailing daily load shapes have been examined to develop the rules for this approach. Two separate, but similar, algorithms have been developed to provide one-to-six hour and 24 hour ahead forecasts. These forecasts have bee ....etc

Voltage Source Converter (VSC) based HVDC transmission systems are available in market for power rated between a few MVA to a few hundreds of MVA. The new system results in many application opportunities and new applications in turn bring up new issues of concern. This paper aims at exploring the HVDC transmission systems and also presents a comprehensive investigation on one of the concerned issues, which is the contribution of HVDC Light? to short circuit currents. Different AC network conditions, load conditions and fault types are considere ....etc

This system uses RF transmission technology. The RF transceiver module which I use has a range up to 100 metres in ideal conditions. This module can transmit and receive 4-bit parallel data with or without 8 address bits using a specific encoder and decoder ICâ„¢s. Another module can be designed such that it can transmit and receive 8-bit parallel data with or without 10 address bits using a specific encoder and decoder ICâ„¢s. The advantage of having the address bits is that message transfer can be made secure.
8-bit ....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

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 :
(A)15uF

(C )60 uF
(D)7.5 u.F

3.Resistance of a 230 V 100 W bulb is R1 and that of a 230 V 75 W is R2. Then,
(A)R1= R2
(B)R1 > R2
(C )R1 < R2
(D)R1 - 2R2
