Microbial electrosynthesis (MES) uses microbes and electricity to convert CO2 high-grade chemicals alleviating greenhouse gas (GHG) emissions. Little is known on the environmental loads associated with scale-up of technology. Initially, MES impacts synthesizing acetic, formic, or propionic acids, methanol, ethanol were assessed using GaBi LCA software, produced 60% from fossil fuels. The result...

In an integrated aircraft design and analysis practice, Life Cycle Cost (LCC) is essential for decision making. The LCC of an aircraft is ordinarily partially estimated by emphasizing a specific cost type. However, an overview of the LCC including design and development cost, production cost, operating cost and disposal cost is not provided. This may produce biased cost estimates. Moreover, air...

This paper aims to analyze product life cycle, introduce green design concept and integrate it into so as establish feasibility path combining with China’s national condition. Through case analysis, five principles of co-creation, material reduction, packaging, replacement from identical were summarized according the attributes figment, product, commodity, article waste. The whole process was a...

This paper presents a new graduate level cost analysis course that has been taught in the Mechanical Engineering Department at the University of Maryland. The objective of this course is to provide students with an in-depth understanding of the process of predicting the cost of systems. Elements of traditional engineering economics are melded with manufacturing process modeling, life cycle cost...

IT-Security requires specific enhancements and tailoring during the complete life cycle of the product or system, including a security focused SW-engineering process. One of the key technologies to manage the software engineering process is the use of a tool driven Software Configuration Management. Software Configuration Management (SCM)[10] is an aspect of establishing that the functional req...
