Executive summary Book Binder’s club was trying to implement a focussed direct mailing campaign through use of database marketing and marketing models. Three different marketing models were developed using historical data of 1600 records and then the model was tested for efficacy on a holdout data of 2300 records. It was found the Regression and Logit (customer choice model) were most effective while RFM model failed to given any leverage above the random mailing campaign that BBC employed prior

radio-frequency (RF) current in antennas and transmission lines is another example of AC. The usual waveform of an AC power circuit is a sine wave. In certain applications‚ different waveforms are used‚ such as triangular or square waves. DC (direct current) - DC (direct current) is the unidirectional flow or movement of electric charge carriers (which are usually electrons). The intensity of the current can vary with time‚ but the general direction of movement stays the same at all times. As an adjective

Alternating current bridges….it’s applications and various perspectives revealed….. ALTERNATING CURRENT BRIDGES:- INTRODUCTION:- A bridge circuit is a type of electrical circuit in which two circuit branches (usually in parallel with each other) are "bridged" by a third branch connected between the first two branches at some intermediate point along them. The bridge was originally developed for laboratory measurement purposes and one of the intermediate bridging points is often adjustable when

measured the resistance of a passive resistor. Pictured below are examples of a simple resistor and an a simple circuit that shows how Ohm’s Law works. Procedure: First‚ the group had to record the manufacturer‚ part number and serial number of the Direct Current (DC) power supply and of the Digital Multi Meter (DMM). They are as follows: Manufacturer | Part Number | Serial Number | Tektronix | CDM250 | TW54020 | Tektronix | PS280 | TW60392 | Then‚ a resistor was

What’s the difference between resistance and resistivity? Resistance is the obstruction offered to the flow of current by a conductor. Resistivity is the obstruction offered to the flow of current by UNIT AREA OF the conductor. So basically‚ resistance is the property of the object (say a copper wire)‚ whereas resistivity is the property of the substance (copper). And so resistance depends upon the properties of the object. Whereas resistivity depends upon the properties of the metal.
