CHAPTER 1 1.0 INTRODUCTION Students’ Industrial Work Experience Scheme (SIWES) is a skill development program designed to prepare students of Universities‚ Polytechnics/monotechnics and colleges of education for transition from the college environment to work (Akerejola 2008). Oyedele (1990) state that work experience is an educational program in which students participate in work activities while attending school. 1.1 brief histories of SIWES The Students’ Industrial Work Experience Scheme (SIWES)

Pister Department of Electrical Engineering and Computer Sciences‚ University of California‚ Berkeley (jmk‚ randy‚ pister} @Ieecs. berkeley.edu Abstract Large-scale networks of wireless sensors are becoming an active topic of research. Advances in hardware technology and engineering design have led to dramatic reductions in size‚ power consumption and cost for digital circuitry

The parts included are illustrated in figure 1.1‚ where a conceptual block diagram of a GSM transmitter and receiver system is sketched. Only the highlighted blocks are implemented. The voice interfaces including microphone‚ speech encoder/decoder‚ and loudspeaker are not intended to be included in the toolbox. Instead‚ to supply the input signal to

earlier this is a really simple project‚ so simple that not even an embedded computer (microcontroller) is used. The emphasis is just on the mechanical design and some basic circuitry. We learn the interface of the commercially available RF transmitter and receiver module coupled with HT12E/D pair (Encoder/Decoder) to transfer data over the air to the motor driver L293D.

both amplitude and phase) will be obtained at the terminals of antenna A if the same emf is applied to the terminals of antenna B.” Figure1: reciprocity theorem of antenna The strong reciprocity theorem implies that the transmitter voltages VA and VB are related to the receiver currents IA and IB by V_A/I_B =V_B/I_A for any pair of antennas A and B. It is assumed that the emfs are of the same frequency and that the media are linear‚ passive and also

The radio broadcasting industry creates and licenses content to play on radio stations‚ which are received by radio receivers. Radio Waves Satellites also communicate via radio waves. More like light than sound‚ radio waves are comparatively low frequency waves in the
