Editorial: Sustainable development of energy, Water and Environment Systems
2020
In 2018 the Conference on Sustainable Development of Energy, Water and Environment Systems (SDEWES) was held in three different locations and periods, so as to offer to the scientific community working in the field several opportunities to share and discuss new ideas and disseminate results of research activities. The 1st Latin American SDEWES Conference was held in Rio de Janeiro (Brasil) in January 28–31 and attracted 180 scientists from 35 countries, with a high number of contributions mainly from Southern American and European academics and professionals, who reciprocally enriched about emerging issues in the field of sustainable development in these continents. Also, the participants a…
Order allocation in a multiple suppliers-manufacturers environment within a dynamic cluster
2015
This study faces the problem of how to evaluate order allocation strategies in a multiple suppliers-manufacturers environment within a dynamic industry cluster that is an environment in which suppliers adopt a policy based on their performance to select the clusters in which to operate. Therefore, the allocation strategy performed by the manufacturers is crucial to keep a long-term supply chain partnership with a specific industry cluster. We use simulation to evaluate order allocation strategies under different market conditions. We show how an allocation strategy that takes into account the whole supply chain’s perspective leads to a sustainable development of the clusters of suppliers.
Human Factor and LEAN Analysis at Industrial Manufacturing Plants
2018
The aim of the research was to find out effective identification and prevention of ergonomics problems in industrial metal processing manufacturing plant, based on human factor workload analysis and LEAN failure mode and effect analysis. Creation of safe, effective work places, emphasizing human oriented approach and implementing ergonomics in business process management is one of the main conditions for sustainable development of an enterprise. For the research were chosen packaging, assembling and quality control manufacturing plant operations due to main complaints from workers about physical overload, intensive work pace and task complexity. Human factor analysis provides holistic under…
Arguments in Favor of Moving to a Sustainable Business Model in the Apiary Industry
2017
Abstract Today’s society faces major challenges in meeting future global food demands and solving biodiversity loss, and it quickly needs to find ways in addressing these issues. The places to look for solutions come from the economic sectors that employ the most powerful pressure on these issues such as agriculture. Apiculture, as a branch of agriculture is being more and more recognized as sustaining human life and contributing to sustainability. However, the sector records a progressive decline of honey bees. Therefore, a rapid restructuring needs to take place in agricultural markets, in general, as well as in apiary agribusinesses. Although important, technological progress is insuffic…
Sustainable and cost-efficient energy supply and utilisation through innovative concepts and technologies at regional, urban and single-user scales
2019
Abstract The environmental impact of the energy sector and the security and economics of energy supply and utilisation have been raising increasing concerns, stimulating the search for innovative solutions for a sustainable use of resources. This article provides an overview of published research in this area, with a focus on papers contributed in special issues of leading journals dedicated to the series of Conferences on Sustainable Development of Energy, Water and Environment Systems (SDEWES), including the articles in the current special issue. Based on this review, research trends are identified and achievements supporting the energy transition are highlighted. The studies that focused…
Environmental modelling of aluminium based components manufacturing routes: Additive manufacturing versus machining versus forming
2018
Abstract Additive Manufacturing represents, by now, a viable alternative for metal-based components production. Therefore the designer, often, has to select among three options at process design stage: subtractive, mass conserving, and additive approaches. The selection of a given process, besides affecting the manufacturing step impact, influences significantly the impact related to the material production step. If the process enables a part weight reduction (as the Additive Manufacturing approaches do) even the use phase is affected by the manufacturing approach selection. The present research provides a comprehensive environmental manufacturing approaches comparison for components made o…
A methodology for the environmental comparison of metal shaping technologies: an in-depth analysis on recycling related issues
2015
The reduction of CO2 emissions is an urgent objective to pursue. The scientific and the industrial world have gathered such challenge, starting to find out energy- and resource-efficient manufacturing strategies. From the literature review, in the domain of environmental impact analysis of manufacturing processes, two relevant knowledge gaps can be spotted: (1) the metal forming processes (and, in particular, the bulk forming processes) are still not well documented, and (2) there is a lack of systematic and comparative studies on energy and material flows enabling the identification of environmentally-friendly manufacturing design strategies. This research offers a contribution to a better…
Robust three-dimensional best-path phase-unwrapping algorithm that avoids singularity loops.
2009
In this paper we propose a novel hybrid three-dimensional phase-unwrapping algorithm, which we refer to here as the three-dimensional best-path avoiding singularity loops (3DBPASL) algorithm. This algorithm combines the advantages and avoids the drawbacks of two well-known 3D phase-unwrapping algorithms, namely, the 3D phase-unwrapping noise-immune technique and the 3D phase-unwrapping best-path technique. The hybrid technique presented here is more robust than its predecessors since it not only follows a discrete unwrapping path depending on a 3D quality map, but it also avoids any singularity loops that may occur in the unwrapping path. Simulation and experimental results have shown that …
Hybrid robust and fast algorithm for three-dimensional phase unwrapping
2009
We present a hybrid three-dimensional (3D) unwrapping algorithm that combines the strengths of two other fast and robust existing techniques. In particular, a branch-cut surface algorithm and a path-following method have been integrated in a symbiotic way, still keeping execution times within a range that permits their use in real-time applications that need a relatively fast solution to the problem. First, branch-cut surfaces are calculated, disregarding partial residue loops that end at the boundary of the 3D phase volume. These partial loops are then used to define a quality for each image voxel. Finally, unwrapping proceeds along a path determined by a minimum spanning tree (MST). The M…
Clustering-based robust three-dimensional phase unwrapping algorithm
2010
Relatively recent techniques that produce phase volumes have motivated the study of three-dimensional (3D) unwrapping algorithms that inherently incorporate the third dimension into the process. We propose a novel 3D unwrapping algorithm that can be considered to be a generalization of the minimum spanning tree (MST) approach. The technique combines characteristics of some of the most robust existing methods: it uses a quality map to guide the unwrapping process, a region growing mechanism to progressively unwrap the signal, and also cut surfaces to avoid error propagation. The approach has been evaluated in the context of noncontact measurement of dynamic objects, suggesting a better perfo…
