Optimization models can support decision-makers in the synthesis and operation of multi-sector energy systems. To identify optimal design a low-carbon system, we need to consider high temporal spatial variability electricity supply, sector coupling, environmental impacts over whole life cycle. Incorporating such aspects optimization is demanding. avoid redundant research efforts enhance transpa...

As well known, the transportation industry and its related infrastructure including railway roads, require very high construction costs. In addition, excessive use of natural resources energy for maintenance has highlighted need adapting purposeful planning with regards to sustainability impacts. infrastructure, focus should be minimize consumption, Greenhouse Gas emissions other environmental ...

Abstract Purpose The primary objective of this study was to evaluate the environmental impact and financial cost repairing surgical scissors. Methods We used life cycle assessment (LCA) analysis estimate impacts functional unit one use a reusable scissor (manufactured in Germany UK), three baseline scenarios were compared: no repair, onsite (hospital), offsite (external contract) repair. This ‘...

Recently, immigration and its socio-economic aspects have been in the centre of European Union leaders’ agenda. In this paper, we apply National Transfer Accounts (NTA) methodology to calculate complete set NTA results for immigrants natives five EU countries. We find that due lower labour income, which cannot be offset by consumption, experience a shorter independence period much aggregate lif...

This paper presents a framework for guiding the design of new materials to enhance the sustainability of systems that utilize these materials throughout their production, use and retirement. Traditionally, materials engineering has focused on the interplay between material microstructure, physical properties, processing, and performance. Environmental impacts related to the system’s life cycle ...

in this research we have presented a local model for implementing systems engineering activities in optimized acquisition of electronic systems in electronic high-tech industrial. in this regard, after reviewing the literature and the use of documents, articles and latin books, we have collected system acquisition life cycle models from different resources. after considering the criteria of the...
