In the wake of globalization,many modern manufacturing companies in Norway have come under intense pressure caused by increased competition,stricter government regulation,and customer demand for higher value at low cost in a short time.Manufacturing companies need traceability,which means a real-time view into thenproduction processes and operations.Radio frequency identification（RFID） technology enables manufacturing companies to gain instant traceability and visibility because it handles manufactured goods,materials and processes transparently.RFID has become an important driver in manufacturing and supply chain activities.However,there is still a challenge in effectively deploying RFID in manufacturing.This paper describes the importance for Norwegian manufacturing companies to implement RFID technology,and shows how the intelligent and integrated RFID（n-RFID） system,which has been developed in the Knowledge Discovery Laboratory of Norwegian University of Science and Technology,provides instant traceability and visibility into manufacturing processes.It supports the Norwegian manufacturing industries survive and thrive in global competition.The future research work will focus on the field of RFID data mining to support decision-making process in manufacturing. 相似文献

Correctly coding materials and identifying characters marked on materials are very important for steel manufacturing industry to realize informatization management and intelligent manufacturing. However, the steel products manufacturing is often in a high temperature environment, and there are a lot of material storage and retrieval processes, workers are not easily close to the environment and complete tasks, so it is a great challenge to automatically mark and identify characters on the steel products. This paper presents a framework of label characters marking and management for steel materials, furthermore, a kind of marked characters online detection and tracking method has been provided based on machine vision. In addition, some experiments have been done in BaoSteel to mark characters on hot billets and recognize them in multi situations, and the results show that the proposed method is practical, and has provided a helpful exploration in obtaining accurate fundamental data for the intelligent manufacturing system in steelworks. 相似文献

In Shakespeare’ s Merchant of Venice,Portia is portrayed as a legal expert.Considerable scholarly work has been devoted to the discussion of the play,and Portia’ s ruling appears to be supported by a majority of scholarly commentary.However,a number of important legal issues regarding the contract represented in the play require immediate attention.This article attempts to re-evaluate Portia’ s ruling and the conventional views on Portia as a legal expert by considering the issues in question within a recent framework of law,and will argue that Portia’ s role as a legal expert is questionable.Antonio,Bassanio,and Shylock can all ’ walk free’. 相似文献

The reconfigurable manufacturing system （RMS） is the next step in manufacturing, allowing the production of any quantity of highly customized and complex parts together with the benefits of mass production. In RMSs, parts are grouped into families, each of which requires a specific system configuration. Initially system is configured to produce the first family of parts. Once it is finished, the system will be reconfigured in order to produce the second family, and so forth. The effectiveness of a RMS depends on the formation of the optimum set of part families addressing various recon figurability issues. The aim of this work is to establish a methodology for grouping parts into families for effective working of RMS. The methodology carried out in two phases. In the first phase, the correlation matrix is used as similarity coefficient matrix. In the second phase, agglomerative hier archical Kmeans algorithm is used for the parts family for mation resulting in an optimum set of part families for reconfigurable manufacturing system. 相似文献

This paper describes the differences between the Chinese and American higher education system, and different issues behind these differences along with history and contemporary complexities, and analyzes the reason of its emergence, then how to solve these issues. I studied at Iowa Wesleyan College in America for two and a half years. In order to further understand American higher education system, I interviewed a librarian of Iowa Wesleyan College named Sherril Gibbs. And I have used a lot of data of the department of education USA government from Wikipedia and other sources in my paper. Then this paper finds that Chinese and American higher education system has their own strengths and weaknesses. Both the systems have a need to learn from each other to execute a better education system and to ensure development of all students as per their interest and abilities. 相似文献

Cased explosives generate highly energetic fragments as their casing breaks up. Due to the complexity of casing fragment related behavior such as embedment, perforation and ricochet, it may be insufficient to use equivalent triangular pressure loading in fragment impact simulations. This simplified method may over- or under-predict the target response. Recently, a procedure using contact techniques has been proposed to overcome such difficulties. It has been shown that the new method has the inherent capability in modeling the multi-piece and multi-hit fragment impact problems in a more realistic way. To investigate the applicability of the proposed method to simulations involving multi-layer penetration, the selected problems of fragment impact on multi-layer targets are described in this paper. It is demonstrated that this method is capable of predicting the complicated multi-layer structural response caused by fragment impact and penetration. Modeling procedures and some technical issues are also discussed. 相似文献

Although the impact of road transport on urban air quality has achieved a high profile in China, still greater attention is required as it has not yet been considered fully even in relation to the road network linking cities and urban areas. Strategic environmental assessment （SEA） is a systematic and comprehensive process for evaluating the environmental impacts of a policy, plan or program in publicly accountable decision-making. Air pollution has been recognized as a significant issue in most transport SEA practices. The Strategic Environmental Assessment of the Hubei Road Network Plan （2002-2020） （HRNP） was introduced as one of the World Bank＇s pilot SEA projects. An effective framework was developed to investigate the functional relationship between the road network and its potential air pollutant emissions. In this study, two indicators were identified： emission intensity/ inventory of pollutants and the spatial distribution of the most polluted areas. Because strategic actions are inherently nebulous and data quality is often disappointing, three alternative scenarios were employed to address uncertainties and data/scale issues. Calculations were made using emission models and results were analyzed with the help of statistical tools and the geographic information system （GIS）. The results from the project implementation and the feedback from the World Bank have both shown that the proposed framework is effective in the transport SEA process. 相似文献

For the past few decades, many countries have been giving increasing stress on expanding their higher education system, in the belief that greater access to higher education will bring abundant rewards in the era of globalization and knowledge-based economies. Taiwan is no exception. Between 1986 and 2006, the government of Taiwan dramatically expanded the number of higher educational institutions from 28 to 147, expecting that this action would enhance educational equity and lead to greater economic prosperity. Popularization, however, does not necessarily result in equity. To be sure, the increase in the number of institutes of higher education in Taiwan has made it possible to accommodate almost all interested students. Yet, because the government has failed to make commensurate increases in public funding for higher education, the quality of university education in Taiwan has seriously deteriorated. Moreover, since many students from poor families still cannot afford the increasingly expensive cost of higher education, neither equity nor equality of opportunity has been achieved. In light of this phenomenon, this article focuses on： （1） describing the changes which Taiwan＇s higher education system has undergone over the past two decades; （2） examining the equity issues relating to higher education in Taiwan; and （3） putting forth some suggestions which Taiwan＇s policy makers can use to address the problems which have arisen as a result of the expansion of higher education. 相似文献

Looking the progress of cyber based information system in railways, air ways, commercial institutions, industries, medical institutions etc. a pertinent questions is raised that why not in agriculture？ It is however, realized that due to short supply of extension workers, their lower educational level and least per capita extension expenditure, the demand based extension services are not been provided to different kinds of clients. Due to diversification of agriculture, the needs are varying from farmer to farmer and area to area. Farmers need different calculated feasible, viable and economical practices to follow for better output and income. The socio-economic and agro-climatic situation of farmers in the same village is also different. Therefore, demand based extension services cannot be possible through our conventional system of extension with the available human and financial resources. So far, extension agents give the information what ever they know and not that what the farmers need. It is therefore suggested to develop cyber based extension system in our country, which provides all required information about all possible questions of the farmers. Keeping this point in view, an effort was made to develop an Expert System of Extension at Division of Agricultural Extension, Indian Agricultural Research Institute New Dlehi-12. The system was built in two phases. In the first phase the agricultural information of the selected crops have been collected from the authentic sources and stored in the form of a database. In the second phase, the decision rules were formulated and coded in the expert system. Both these phases are finally combined to form cyber-based expert system, which is hosted on the Internet for the use of the farmers and general public. This is a best combination of man and machine for efficiency and need to based on dissemination at a time to all farmers. 相似文献

Under the setting of globalization, in the late 1970s, China began to carry out ’the reform and opening-up policy’. During 30 years reform process, Chinese economy has a great growth. The ’market mechanism’ and its effectiveness were adopted by Chinese people. With the deep reform of health system, Chinese government delegates more decision-making power to the hospitals, thus ’in employment terms, as two of largest industries (health and education) in every country’ (Meadmore P. 1999 p.91), the reform of education has become a hot topic in social debate. In other words, in the field of education in China today, marketization of education is highly focused, causing concerns of various social classes: What are the reforms? What are the results reforms bring about? On exploring the effects of globalization on Chinese education in modernity and presenting advantages and disadvantages in the process of the ’market mechanism’ working in and through education to reconsider a market education system creates an external competition for public schools. 相似文献

Mobile computing facilities may provide many assets to the educational process. Mobile technology provides software access from anywhere and at any time, as well as computer equipment independence. The need for time and place independence is even greater for medical instructors and medical students. Medical instructors are usually doctors that have to treat patients on top of their tutoring duties. Mobile features are complementary to web-based features for desktop computers to a high extend in asynchronous e-learning environments. Time and place independence is also a considerable potential for medical students with overloaded educational duties. This paper examines the degree of the usefulness of mobile facilities for medical instructors who wish to author and manage their courses by using a mobile authoring tool. Furthermore, this paper investigates how acceptable and useful the mobile features of an e-learning system have been to medical students who have used the system, in comparison with the use of the system through a desktop computer. In addition, it investigates usability issues. 相似文献

Time compression in supply chains is a crucial aspect involved in the integration of warehousing and transport operations in the manufacturing industries. Sup- ply chain flows could be interrupted due to many sources of delays that lead to additional time in dispatching process and reduction in customer service level. The problem considered in this paper consists of long waiting times of loading vehicles inside the plant. This work presents a simulation-based study to minimize vehicle dispatching time in a steel wire plant. Value stream map is developed to present a system perspective of processes involved in the overall supply chain. Process activity mapping is com- pleted to provide a step by step analysis of activities involved in the vehicle dispatch process. A simulation model is developed for the system and a new model is proposed to improve the delivery performance by mini- mizing vehicles＇ waiting time. 相似文献

It is inevitable that as a result of progress in technology and the changes in the ways with which design is conceived, interior architecture schools should be updated according to these requirements and that new educational processes should be tried out. It is for this reason that the scope and aim of this study have been determined as being the formulation of a hybrid educational model for the integration of digital approaches to design within the interior architecture education system. Within the chosen scope and aim of this study, and as a methodology, various algorithmic and parametric approaches have been applied in various practical applications as digital design instruments, and conclusions have been reached concerning the advantages they offer within the design process. The advantages and disadvantages, concerning interior architecture education, of digital approaches to design over the traditional design method, have been presented on the basis of results found during practical applications of digital design, the information found in publications about this subject. A hybrid educational model for the restructuring with digital design instruments of interior architecture education and design studios as experimental areas has been presented. Thanks to this proposed model, the establishment of a computer formatted analytic design system in the guise of dynamic systems will get easier and, the opportunity of restructuring the process and conception of design will also present itself. As the effects of this method are reflected on the products, new geometric approaches and typologies will appear, with the result that designs and digital instruments will constantly be developed and will evolve. In conclusion, educating the designers of the future according to the essence of these approaches will make it possible to train professionals who correctly use and understand the technologies being developed, who have a critical stance, and who can produce renewable designs. 相似文献
