The different methods for definition of space, object coordinate system are also reviewed. It is suggested that the habitu-ally-practised rotation angle system for aerophotogrammetry in China should be used for the future teaching and resaarching work in the close range photogrammetry, and that the rotation angle system for terrestrial deformation photogrammetry should be left out in order to avoid the confuse and reduce the amount of expanse for making softwares. It has been emphasized that there are three improtant aspects in the close range control work with high accurary using the conventional method of engineering surveying: the use of standard scale for measurement of distance between two general stations, the accurate determination of start direction line between two general stations and the handling method of influence of 2C change. A method for setting up industrial surveying control net with extra-high accuracy ±(0.05–0.20) mm is presented by the author. This kind of industrial control net is necessary for batch process of large industrial components with purposes of measurement, inspect and lofting. There are some special methods of control work in the close range photogrammetry, including two methods presented by the author.展开更多

First, color shift is introduced and a few examples are given from different real-life industrial conditions. Different degradation mechanisms in different parts of the system are also explained. Different materials used as lenses/encapsulants in light-emitting diode(LED)-based products are introduced and their contributions to color shift are discussed. Efforts put into standardization, characterizing, and predicting lumen maintenance are also briefly reviewed in this paper.展开更多

In this paper, the interplay between technology, market and government in telecommunications is discussed briefly, and then we introduce technology and government into the traditional SCP(Structure – Conduct – Performance) paradigm to develop an industry analysis framework called TGM(SCP)(Technology – Government – Market(Structure – Conduct – Performance)). Based on this framework, we present the spiral coevolution model which elaborates on the interaction mechanism of technological innovation with government regulation and market dynamics from the perspective of industry evolution. Our study indicates that the development of the telecommunications industry is the result of the coevolution of technology, government regulation and market forces, and among the three actors, technology is the fundamental driving force. Relative to the "invisible hand"(market) and "visible hand"(government), we conceptualize technology as the "third hand", which fundamentally drives the development of telecommunications industry in coordination with the other two hands. We also provide several policy implications regarding these findings.展开更多

They have explored the application of these perspectives to the central substantive theme emerging from global educational analysis of planning organisation and behaviour, that is, the process of managerial control. This study focuses upon the global educational environment within global management of knowledge and substantive parameters set by the previous studies. It carries out this task in a number of respects. First, it reviews the various explanations that have been offered for the historical development of modern planning--both as a unique organisational form and as a distinctive educational worldview. Second, it considers various conceptions of managerial work that have evolved within educational analysis since the inception of the corporate system enters into global education societies during the early years of the 21st century. Third, it assesses the implications of empirical research on the three major levels of planning that haw: crystallised within contemporary corporate hierarchies. These are made up by the elite group of staffs and senior lecturers, and the middle strata of line workers, who are the superintendents of production. A concluding section evaluates the general contribution educational analysis has made to our understanding of the nature of managerial work.展开更多

The result shows that there are different inhibition types at differ-ent lead contents. Higher lead content leads to more inhibition granular sludge, and at the same time, the time of gas recovery is different. Lower lead content per microorganism results in sooner sludge recovery. Microorganisms have a good ability to resist lead toxicity.展开更多

Services were the responses of events that can be accessed programmatically on the Internet by HTTP protocol. Services were obtained according to some standardized service templates. The workflow engine's flexible control to a request was bound to appropriate services and their providers by using a constraint-based, dynamic binding mechanism. Hence, a flexible and collaborative business was achieved. The workflow management system supports virtual enterprise, and the styles of virtual enterprises can be adjusted readily to adapt various situations.展开更多

EOS is responsible for the entire software and hardware resource allocation, scheduling work and coordinating concurrent control activities; some more successful applied EOS products have been presently launched. With the development of lnternet technology, information appliances and the universal application of miniaturization and specialization of EOS, EOS started from a single weak situation to a higher professional direction with strong functions.展开更多

However, it is necessary to measure the productivity, so that the system of measurement and control of manufacturing processes are an element critical as to ensure greater visibility of the flow's restrictions, minimized when detected properly. In this case, the automation of factory's measurement process can effectively contribute to ensuring the effectiveness of the function control of a manufacturing system. It is important to consider that the automation of the system of measurement and control of manufacturing processes, of complex environment, is heavily dependent of IT tools applied directly in the interface computational between the operation systems and the corporate systems. This heavy reliance, if exploited technically properly, allows that automation of the system of measurement and control of production makes the access to time real of availability of manufacturing process's data, such as processing time and setup time that it can export to a specialist software in programming production, for example, feasible. In this paper, the automation of the system of measurement and control of production is approached, in order to identify the main possibilities of the design of an information system capable to integrate the flow of information in an environment internal on manufacturing organizations, with emphasis in the digital manufacturing paradigm.展开更多

This is due to the fact that such factors as financial solvency, financial operations, profitability, growth capacity and the ability to generate cash exert effect upon the long-term stability of the financial competitiveness.展开更多
