A number of recent publications point to the important role of eco-design approaches in risk mitigation for critical materials supply. The core of eco-design is life cycle thinking - usually as some form of Life Cycle Assessment (LCA) approach together with a set of generic guidelines such as checklists, etc. There has however been little appraisal of the extent to which eco-design offers opportunities...
The energy saving potential for lighting products containing light-emitting diodes (LED) is significant and the strategic importance of the LED technology is reflected in the current and upcoming market development. The commercial/public/architectural lighting sector will by far be the fastest growing market segment during the next decade. However, LED-based product systems contain many critical resources...
There are potential eco-efficiency benefits from ‘closing the loop’ in product life cycles. However, its implementation is not always straightforward especially for manufacturers of complex products such as electronic devices. They need to know how, where and when to close the loop in order to achieve the desired improvement in eco-efficiency. To help them do this, we propose a methodology that is...
The Femtoprint project uses femtosecond lasers to develop a printer for micro-/nano-scale systems. Femtoprint provides a large community of users with the capability of producing their own micro-systems, in a rapid-manner without the need for expensive infrastructures and specific expertise.
The aim of this research is to design and develop a software application to solve the problems that actually occur in the production and stock management processes of plastic molding injection. The application was developed using web pages that work together with a database. The user can check the current status of production process and stock inventory through a web browser of any Local Area Network...
The paper focuses on the role of simulation within the RSB GHG Tool, which is a web-based decision support tool that assesses greenhouse gas emissions of biofuels according to the principles of the Roundtable on Sustainable Biofuels. Using a questionnaire, each operator can specify his individual data and calculate the GHG emission for his production step. To derive the environmental flows required...
Small and medium-sized enterprises (SMEs), which have limited resources, spend the majority of their time on routine business and have difficulty pursuing goals beyond economic efficiency, such as environmental preservation. In this study, using the concept of Material Flow Cost Accounting (MFCA), a simulation model for the Enterprise Resource Planning (ERP) business flow of a Japanese electronic...
This paper attempts to highlight shortcomings in the concept of sustainability and ways to make the concept more workable by presenting the development of an Environmental Management Information System (EMIS) as a combination of discrete event simulation and ecological material flow analysis for production processes. The motivation behind the focus on simulation techniques on one hand and on production...
The present study adopts acoustic means to investigate the articulatory problems from Shandong (Hereinafter, SD) learners on the production of English plosives. The VOT, pitch, and formants were selected as the parameters to examine the manner and place features of the plosives produced by the SD learners. Results demonstrate that the SD learners pronounce the voiced stops as voiceless ones. This...
Intellectual property laws present formidable challenges for digital cultural archiving projects. While cultural institutions may be permitted to make works available to the public, these rights may not cover online publishing or reproduction. Consequently, institutions undertake time-consuming, resource-intensive clearance processes in order to secure licenses for displaying copyright protected cultural...
This paper explores an integrated inter-professional collaborative model and technology for a break-through digital humanities platform called Expressions. This platform was co-created by the Center for Research in Entertainment & Learning (CREL) at Calit2, UCSD and Visual Exchange Network (VEN), which is an hybrid research and production corporation for upstream âcoactive' multi-venue media.
"Cho-Shi" is one form of Japanese carving art. It is a technique that uses a composition of papers of different colors with a certain thickness to carve, and produce concave and convex shapes while expressing colors. This form of art makes a two dimensional picture take a three-dimensional structure, giving an experience which is different from the traditional picture. However, because "Cho-Shi"...
This paper describes the modeling and simulation of High Pressure Roller Crusher (HPRC) for the production of silicon carbide grains. The study is to make a model for simulation of a High Pressure Roller Crusher. A High Pressure Roller Crusher (HPRC) is an important part in the production of silicon carbide, where the grains are crushed into powder form and then sieved into specified sizes based on...
This paper points out: the tradition industrial engineering originated in the manufacturing industry, but the future industrial engineering will be suitable for all the integrated system which contains people and objects; the tradition industrial engineering emphasis on micro-management, but the development of the future industrial engineering will pay first attention to the macro-problems. It has...
Most privately owned businesses are formed to generate profits. Every year, manufacturers loose a portion of potential profits on covering warranty claims. To minimize warranty costs companies focus on product quality improvements. In this project real historical warranty data of three electronic sensors have been analyzed. Two-parameter Weibull distribution to measure sensors' reliability have been...
To investigate an efficient and cost effective method to catalyze transesterification reaction, the lipase immobilized on chitosan beads was introduced in the present paper with a hypothesis that the immobilized lipase could catalyze transesterification to get a high triglyceride conversion. Four immobilization methods namely cross-linking using glutaraldehyde (GLA), activation with 1-Ethyl-3 (3-dimethyl-aminopropyl)...
The following paper reports about the results of the collaboration between 12 higher education institutions in Austria. The purpose of this collaboration was to share institutional practices for supporting educational developments at universities. Rather than to follow a merely functional logic, the paper suggests to focus on the educational products of higher education institutions and to establish...
The article puts forward a distributed control system based on CAN fieldbus, which achieves remotely to monitor intelligently system and diagnose fault in crusher product line MITSUBISHI Q00CPU PLC and CAN bus is used in the system MITSUBISHI GT1575-VNBA touch screen is chosen to monitor the product line. Several measured signals are transmitted to PLC via CAN and distributed I/O modules. This article...
This paper aims to understand the recent REE policies in China, including a series of regulatory measures on mining and extraction of REEs such as full-range plans for rare earth resources with strategic reserves and commercial stockpiles, regime of resource taxes and export tariffs, enforcement of environmental and occupational health standards, control of new project investments, establishment of...
Stylist is designers of the interior space for swellings. The designers not only provide the personalized design scheme but also create a scientific and comfortable living environment for habitant. However, unreasonably designs can bright unnecessary pollution to indoor environment. Therefore, as an important part of decorative design, the production of the pollution from decoration could be controlled...
