The characteristics of power produced from photovoltaic (PV) and Wind systems are based on the weather condition. Both the system are very unreliable in itself without sufficient capacity storage devices like batteries or back-up system like conventional engine generators. The reliability of the system significantly increases when two systems are hybridized with the provision of storage device. Even...
As chemical mechanical planarization (CMP) enables local and global planarization over a wafer surface by the combined effects of chemical and mechanical interactions, process monitoring is becoming an increasingly important in-situ methodology for process control. According to the materials and process, signal characteristics were distinguishable between material and process. In this study, an acoustic...
To mitigate the impact of global warming on the environment, many governments, non-profit organizations, and enterprises have formulated relevant standards to assist enterprises in promoting carbon management, and to encourage the design and popularization of low-carbon products. These standards include: PAS 2050, ISO/TS 14067 and so on. Under these initiatives, enterprises try to disclose the carbon...
The demand for pattern miniaturization on package substrates has been steadily increasing. One technical innovation for the package substrate manufacturing process was chemical mechanical planarization (CMP). In conventional wiring, it was possible to remove extraneous copper through only the etching process. However, etching defects occur with narrower line widths. As the package substrate has a...
The present work aims at analyzing how the adoption of a proactive environmental management via green operational practices (GOPs) correlates to the Green Performance (GrP) of a given set of ISO 9001-certified firms in Brazil. To this end, we elaborated a conceptual framework about environmental management, GOPs, and GrP. Such theoretical foundation supported the development of empirical research...
Energy consumption in the manufacturing sector is becoming a very hot topic due to its significant ecological relevance, especially for energy intensive processes such as machining. Machining finds nowadays large application mainly due to its high performance, in terms of both surface finish and tolerances achievable; as an example this is the key technology in dies and molds production, largely used...
Most maintenance works on building exterior walls are carried out by human labor and a cable-driven system (gondola). This approach involves a safety problem, motivating many recent studies of exterior wall automated maintenance methods. However, the conventional studies have been concentrated only on moving mechanism and the studies on cleaning method and processing of cleaning materials are insufficient...
Greenhouse gas emission has become a recent global concern for green manufacturing. As product low-carbon design is an essential approach to achieve low-carbon manufacturing, which has a profound effect on the product carbon footprint, many researches have been focused on it in recent years with a result of valuable contributions. This paper is devoted to presenting a dynamic programmingbased approach...
The steel industry accounts for the largest share, approximately 27 percent, of global carbon dioxide emissions from the manufacturing sector. Changes in material and energy use, and emissions profiles of the iron and steel manufacturing are the result of complex interrelationships between technological and economic drivers. A better understanding of these changes require special attention paid to...
Traditional information system and managerial mechanism cannot meet the new environment protection regulations; therefore, a new solution must be set up, else it may run the risk of losing the market and the value of product brand.This research focuses on the solutions provided by the network and communication industry, manufacture of the green products, and the establishment of a Webbased green collaboration...
Railway is an environmental friendly method which has been widely used in the land transportation driven by electric powers, without harmful emissions and unhoped traffic jams. And it is important to guarantee the running safety through the technology of rail grinding. However, the empirical processes have limitations on the expanded requirements of frequent and systematic rail grinding. Therefore,...
In this work, a numerical study is performed to know the effect of mode stirrers on the temperature distribution inside a microwave cavity with a conveyor belt system. A 3-dimensional simulation model is built and simulated using the COMSOL Multiphysics software. Since it is very difficult to simulate the mode stirrer’s motion using COMSOL, eleven still angles of the mode stirrers are considered....
Accurate predictions of the amount of harvestable energy available from ambient vibrations are important for design of energy harvesters and for their integration in specific applications. This need has motivated the development of many mathematical models for piezoelectric energy harvesters (PEHs). Existing models, however, require material and geometric PEH data that are often incorrect and/or unavailable...
Regulative measures and rising energy cost foster the trend towards energy efficient manufacturing. However, companies are facing hurdles such as high effort and little expertise when implementing energy efficiency measures. Moreover, the embodied energy of products cannot be determined accurately in eco-assessments of factories. This paper presents a methodology for the reliable prediction of energy...
The benefits of cutting fluids in machining are well known, but their use is accompanied by health and environment hazards. Moreover, strict environmental regulations make the manufacturers to switch over to dry turning, which is not feasible during machining of sticky material like stainless steel and Inconel etc. Therefore, the use of minimal quantities of lubricant (MQL) can be regarded as an alternative...
Due to concerns about environmental protection, product life cycle management for end-of-life has received increasing attention in many industrial sectors. To support these functions, crucial issues have been studied to realize a product recovery management system. Until the present time most research has been concerned with decision making under the assumption that all the relevant and accurate information...
Cellulose, the chain of glucose residues easily obtained from nature, is the most common natural polymer. Owing to its own unique material properties, compared to the conventional usage, nanocellulose (NC) with a crystalline structure can be considered to be used in various industrial applications. As a novel sustainable future material, we review the recent achievements of NC from the view point...
A Rapid Life Cycle Assessment (RLCA) method based on Green features is proposed in order to solve the inherent limitations of conventional Life Cycle Assessment (LCA), such as long period, massive data requirement, which result in difficulties in supporting product conceptual design. Firstly, Green Feature is proposed in supporting the LCA in conceptual design, where a mapping relationship is established...
The extended-range electric vehicle (E-REV) is an electric vehicle concept that has a light engine to allow an extended driving range. One of the most important features of these vehicles, based on electricity, is their ability to recover significant amounts of braking energy in a process known as regenerative braking. The more driving motor operates widely as generator, the more braking energy can...
