摘要:

In a nutshell, the problem with television-lighting control is one of getting the right amount of light in the right place at the right time. This might not seem very difficult—until one considers the situation a little more closely

摘要:

Is the established way of educating present-day scientists and engineers producing successors to such great inventors as Edison, Parsons or Whittle, or is it producing stereo-typed adaptors of long-established designs?

摘要:

Plastics—the man-made replacements for the natural resins and waxes—emerged as a commercial product at the great international exhibition in London in 1862. However, early pioneers sought to imitate and not to improve on Nature. Today, the chemist, physicist, engineer and technologist work together to develop these materials that offer unlimited opportunities to the new technological generation

摘要:

The essential aim of the conference on the use of the young professional engineer, held in London on the 9th October 1970 and organised by the Council of Engineering Institutions London Graduates & Students Joint Committee, was for ‘young engineers’ to give a clear view on how they consider that their profession must change if they are to make a full contribution to society and to Britain's economy, and also if they are to have a satisfying career. The report of the conference will be sent to the CEI, to the constituent Institutions and to other national policy-making bodies.

摘要:

Interest in industrial relations is greater today than it has ever been, and there are very good reasons for this interest. Some of these reasons relate to immediate problems and issues such as the current wage claims, the proposed legislation etc.; but underlying the interest, and away from the immediate ques tions, there is an interest that seeks to determine the main lines of change and development in the future

摘要:

In telemetry systems of greatly differing bandwidths, the sampling of several channels of information can be made more efficient if, instead of sequential sampling, the individual sampling rate of each channel is made a function of its information content. Several procedures for comparing such data are considered in this article, and a design for a multichannel telemetry system is proposed in which a single transmission line is used

摘要:

The growth in the demand for electrical power has led to transmission lines being operated at higher voltages and constructed close to urban areas and installations, where good radiocommunication is important. Because of their large physical size, the lines act as excellent aerials for the transmission of interference signals. These factors have focused attention on the problem of the generation of radio interference by line conductors
