Behaviourist Thoery/ Thorndike’s Theory of Connectionism/ Trial and Error Learning/ S-R Bond Theory Trial and Error is a method of learning in which various response are tentatively tried and some discarded until a solution is attained. E.L.Thorndike(1874-1949) was the chief exponent of th theory of connectionism or trial and error. He was an American Psychologist who conducted Stimulus - Response(S-R) theory experiment with the help of animals. Thorndike was the first to study the

The TRIAC is an ideal device to use for AC switching applications because it can control the current flow over both halves of an alternating cycle. A thyristor is only able to control them over one half of a cycle. During the remaining half no conduction occurs and accordingly only half the waveform can be utilised. Typical / idealised TRIAC & thyristor switching waveforms The fact that the TRIAC can be used to control current switching on both halves of an alternating waveform allows much better

Cl 242 Tutorial 1: Conduction 1. The rear window of an automobile is defogged by attaching a thin heating element to its inner surface. By electrically heating the element‚ a uniform heat flux may be established at the inner surface. For 4 mm thick window glass‚ determine the electrical power required per unit window area to maintain an inner surface temperature of 150C when the interior air temperature and convection coefficient are Ti = 25 0C and hi = 10 W/m2.K‚ while the exterior (ambient )

There are some simple ways to reduce heat loss‚ including fitting carpets‚ curtains and draught excluders. Heat loss through windows can be reduced using double glazing. The gap between the two panes of glass is filled with air. Heat loss through conduction is reduced‚ as air is a poor conductor of heat. Heat transfer by convection currents is also reduced by making the gap is very narrow. Heat loss through walls can be reduced using cavity wall insulation. This involves blowing insulating material

Arrhythmias Arrhythmias are any change from the normal sequence of the electrical impulses in the heart. An arrhythmia is when your heart cannot pump blood effectively. It may happen to fast‚ to slowly‚ or it may happen erratically. When arrhythmias occur; the lungs‚ brain‚ and other organs cannot work properly and they may shut down and be damaged. A normal heart beat is strong‚ muscular pump that is a little larger than a fist and pumps blood continuously through the circulatory system. Arrhythmias
