 513  144. Magnetostriction is defined, basically, as a change in dimension produced in certain ferromagnetic materials when placed in a magnetic field, the phenomenon being reversible. 145. As a matter of fact this is the first approach to communication system design with the disturbance of the channel utilized as the primary criterion in the design. 146. It is assumed that set pulses have been applied to three of the stages so that binary number 11001 is stored in the register. The shaded stages are assumed to be in the binary 1 condition, and the unshaded stages are assumed to be in the 0 condition. 147. Transistors do, however, hold out a promise for smaller, simpler and less expensive computers of very high performance for the future. 148. It is assumed here that the resistivity, thermal conductivity, and thermoelectric power are constant within a branch over the temperature range considered and, consequently, that the Thomson coefficient can be regarded as zero. 149. It is evident that the motor car of to-day could not have been produced in the quantity and quality without the liberal use offorgings. 150. The best procedure is that which gives the greatest reduction, and this maximum reduction may be taken as being a measure of the return to be expected from applying extremum control to a given plant in a given situation. 151. We succeeded in getting Mr. Arthur and Walker's opinion on this question, the former being a scientific worker of a well known laboratory and the latter director of a large plant. 152. It was shown by theoretical physicists that an electron moving at speed could be considered as possessing a wave length, this wave length decreasing with increase in velocity. 153. Although the carrier line signals are transmitted and received over separate cable pairs, they are separated further by being placed in different frequency bands to simplify crosstalk suppression problems. 154. The oral drugs, known chemically as sulfanylureas and biguanides, have greatly reduced the need for insulin injections in many diabetics. All of them were found to be more effective than insulin in lowering cholesterol synthesis in the rat liver tissue. 513 |
