The basic structure of Cable Digital TV Head-end System is presented in this paper. Cable Digital TV Head-end connected between the TV Signal Source and the Transmission Line is a system which can convert a variety of signal sources into a transport stream to meet the exacting standards of the transmission. The transport streams will finally be sent to service terminal by the transmitting device and the existing network. This paper gives the method of constructing Cable Digital TV Head-end System and some useful suggestions about the selection of equipment.

This article aims to find out the efficient design method of intelligent interaction in industrial design. It analyzes its significant impact on industrial design, and looks into three main forms of intelligent interactive design. Through the discussion and comparison of users’ choice based on their behavior characteristics and their selection of the operating signal source, this paper gets a conclusion that the intelligent interactive design goes ahead along with the acceptance of users’ material and spiritual recognition and cooperation, and combines with the ergonomic and product structure knowledge to reach its efficient design method goal for industrial design.

Based on the analysis of origination of the machining errors, and selection of major influencing factors - those errors rising from the machine tool, the fixture, and the cutting tool, the error signal source library was created at the sampling points on coordinates X, Y, and Z. By making use of the written knowledge and workshop experience, the library was extendable and built with technique of ADO database access. And virtual real-time presentation of machining errors on the machined surfaces was also constructed with a mathematical model of weighed random method, considering the error of the sampling points and the drifting of the sampling points themselves from the perfect position. And a virtual measurement system was formed for the test of errors of the machined surfaces of mechanical components programmed with Visual C++ 6.0and OpenGL 3Dgraphical library. An example of the step-shaft with five kinds of tolerances was given and has been shown that the virtual system with the extendable library of errors and model for weighed random method was practical. Such weighed random method presented well the real errors of processing operations on the field with the proper model showing the principle of the error origination in metal machining.

Abstract Some of the foundations of Heyes’ radical reasoning seem to be based on a fractional selection of available evidence. Using an ethological perspective, we argue against Heyes’ rapid dismissal of innate cognitive instincts. Heyes’ use of fMRI studies of literacy to claim that culture assembles pieces of mental technology seems an example of incorrect reverse inferences and overlap theories pervasive in cognitive neuroscience.

The first question to be answered, in seeking coordinate systems for geodynamics, is: what is geodynamics? The answer is, of course, that geodynamics is that part of geophysics which is concerned with movements of the Earth, as opposed to geostatics which is the physics of the stationary Earth. But as far as we know, there is no stationary Earth – epur sic monere. So geodynamics is actually coextensive with geophysics, and coordinate systems suitable for the one should be suitable for the other. At the present time, there are not many coordinate systems, if any, that can be identified with a static Earth. Certainly the only coordinate of aeronomic (atmospheric) interest is the height, and this is usually either as geodynamic height or as pressure. In oceanology, the most important coordinate is depth, and this, like heights in the atmosphere, is expressed as metric depth from mean sea level, as geodynamic depth, or as pressure. Only for the earth do we find “static” systems in use, ana even here there is real question as to whether the systems are dynamic or static. So it would seem that our answer to the question, of what kind, of coordinate systems are we seeking, must be that we are looking for the same systems as are used in geophysics, and these systems are dynamic in nature already – that is, their definition involvestime.

SummaryA routine has been developed for the processing of the 5820 plates of the survey. The plates are measured on the automatic measuring machine, GALAXY, and the measures are subsequently processed by computer, to edit and then refer them to the SAO catalogue. A start has been made on measuring the plates, but the final selection of stars to be made is still a matter for discussion.
