附录B 外文原文 Single gate optimization for plastic injection mold LI Ji-quandagger;, LI De-qun, GUO Zhi-ying, LV Hai-yuan (Department of Plasticity Technology, Shanghai Jiao Tong University, Shanghai 200030, China) dagger;E-mail: hutli@163.com Received Nov. 22, 2006; revision accepted Mar. 19, 2007 Abstract: This paper deals with a methodology for single gate location optimization for plastic injection mold. The objective of the gate optimization is to minimize the warpage of injection molded parts, because warpage is a crucial quality issue for most injection molded parts while it is influenced greatly by the gate location. Feature warpage is defined as the ratio of maximum displacement on the feature surface to the projected length of the feature surface to describe part warpage. The optimization is combined with the numerical simulation technology to find the optimal gate location, in which the simulated annealing algorithm is used to search for the
New Interpretation Module for Open Architecture Control based CNC Systems ABSTRACT CNC technology is the key technology of the machine tools, which are the base of industrial unit computerization. CNC machines are operated by controllers, each of which has a software module inside known as interpreter. The function of interpreter is to extract data from CAM system generated code and convert to controller motion commands. However, with the development of numerical control technology existing CNC systems are limited with the interpreter lacking in expansibility, modularity and openness. In order to overcome these problems open architecture control was introduced. In this paper, a conceptual module of new software system is presented. The developed system is able to interpret ISO 14649 and 6983 code and translate as per internal structure required by the CNC machine. It interprets position, feed rate, tool, spindle etc data and translates to CNC machine. At the mean time it is

A review on current research trends in electrical discharge machining (EDM) Abstract Electrical discharge machining (EDM) is one of the earliest non-traditional machining processes. EDM process is based on thermoelectric energy between the work piece and an electrode. A pulse discharge occurs in a small gap between the work piece and the electrode and removes the unwanted material from the parent metal through melting and vaporising. The electrode and the work piece must have electrical conductivity in order to generate the spark. There are various types of products which can be produced using EDM such as dies and moulds. Parts of aerospace, automotive industry and surgical components can be finished by EDM. This paper reviews the research trends in EDM on ultrasonic vibration, dry EDM machining, EDM with powder additives, EDM in water and modeling technique in predicting EDM performances.

Numerical control technology and equipping development trend and countermeasure Equip the engineering level, level of determining the whole national economy of the modernized degree and modernized degree of industry, numerical control technology is it develop new developing new high-tech industry and most advanced industry to equip (such as information technology and his industry, biotechnology and his industry, aviation, spaceflight, etc. national defense industry) last technology and getting more basic most equipment. Marx has ever said 'the differences of different economic times, do not lie in what is produced, and lie in how to produce, produce with some means of labor '. Manufacturing technology and equipping the most basic means of production that are that the mankind produced the activity, and numerical control technology is nowadays advanced manufacturing technology and equips the most central technology. Nowadays the manufacturing industry all around the world adopts n

DOI 10.1007/s10615-006-0060-6 ORIGINAL PAPER Karen Horney and Psychotherapy in the 21st Century Wendy B. Smith Published online: 8 August 2006 copy; Springer Science Business Media, Inc. 2006 Abstract Many ideas currently circulating in the psychological and psychoanalytic communities have correspondence with the theories put forth by Karen Horney during the first half of the twentieth century. This paper provides an overview of Horneyrsquo;s theoret- ical departures from Freud and an introduction to her then controversial views of motivation and relation- ship. Compatibility between Horneyrsquo;s ideas and attachment theory, self-psychology, intersubjectivity, and the person in the environment is discussed. Two clinical cases are presented, illustrating Horneyrsquo;s the- ory and approach.

WRONGFUL DISCHARGE LAWS AND INNOVATION Viral V. Acharya Ramin P. Baghai Krishnamurthy V. Subramanian Working Paper 18516 NATIONAL BUREAU OF ECONOMIC RESEARCH 1050 Massachusetts Avenue Cambridge, MA 02138 November 2012 ABSTRACT We show that wrongful discharge laws – laws that protect employees against unjust dismissal spur innovation and new firm creation. Wrongful discharge laws, particularly those that prohibit employers from acting in bad faith ex post, limit employers ability to hold up innovating employees after the innovation is successful. By reducing the possibility of hold-up, these laws enhance employees innovative efforts and encourage firms to invest in risky, but potentially mould-breaking, projects. We develop a model and provide supporting empirical evidence of this effect using the staggered adoption of wrongful discharge laws across the U.S. states. 1 Introduction A recent strand of the literature emphasizes the criti
Dispute prevention and resolution in public services labour relations: Good policy and practice by Clive Thompson Foreword by Carlos R. Carrioacute;n-Crespo International Labour Office Geneva 2010 Preface Social dialogue, including collective bargaining, is one of the core principles of the ILO. It should form part and parcel of the regulation of labour relations in the public sector. Dialogue and bargaining can and should be key contributors to public sector efficiency, performance and equity. However, because competing interests are involved, neither is conflict-free. If governments and public sector unions are to be encouraged to bring these dynamics into public sector work, where industrial peace carries a special premium in the public mind, then considerations of conflict management must be uppermost. This is more relevant than ever in times of fiscal consolidation and austerity measures. In 2005, the ILOlsquo;s Sectoral Activities Department
Sustainability and customer relationship management: current state of research and future research opportunities Anna-Luisa Muuml;ller Abstract As recent years have seen an on-going discussion in science and industry about customer relationship management on the one hand and sustainability on the other hand, the synthesis of both trends sustainability and customer relationship management is gaining increasing importance. Within the multiplicity of scientific publications exploring sustainability in customer-related areas, this paper providfes an overview on the current state of research on sustainability-oriented customer relationship management. We analyse the present literature predominately with regard to the core areas of CRM, i.e.marketing, sales and service. It becomes evident that almost no research takes an integrated perspective on what shapes sustainability activities targeted at the customer and analyses how customers and sustainability interdigitate.
