... The participation of power-intensive industrial chemical processes in short-term electricity markets (STMs) in addition to long-term markets (LTMs) is considered. STMs are highly volatile with dynamics of the order of seconds to minutes. It is thus imperative that production scheduling for chemical process participation in such markets (1) be carried out repeatedly to reflect ongoing changes in ma ...
... Among 45 Russula species and infraspecific taxa described by J. Blum, only few are currently accepted. Here we present a case study on R. formosa nom. illeg. (homotypic synonym of R. blumiana), R. decipiens var. ochrospora nom. inval. and R. roseobrunnea. The study is based on sequences and morphological observations of authentic herbarium material determined by J. Blum. The sequence data demonstr ...
... Long-term reservoir management often uses bounds on the reservoir level, between which the operator can work. However, these bounds are not always kept up-to-date with the latest knowledge about the reservoir drainage area, and thus become obsolete. The main difficulty with bounds computation is to correctly take into account the high uncertainty about the inflows to the reservoir. In this article ...

Abstract:
... This paper investigates the applicability of model emulation to speed up simulation time of CPU intensive environmental models. Polynomial chaos expansion (PCE) emulators are constructed for three case studies of increasing complexity. The level of emulator training and the order of polynomial necessary to sufficiently build accurate emulators for each model are investigated. Although the PCE emul ...

... Dynamic Energy Budget (DEB) theory constitutes a coherent set of universal biological processes that have been used as building blocks for modeling biological systems over the last 40 years in many applied disciplines. In the context of extracting parameters for DEB models from data, we discuss the methodology of fitting multiple models, which share parameters, to multiple data sets in a single pa ...

Abstract:
... Currently, renewable energy is rapidly developing across the world in response to technical, economic and environmental developments, as well as political and social initiatives. On the other hand, excessive penetration of distributed generation (DG) systems into electrical networks may lead to various problems and operational limit violations, such as over and under voltages, excessive line losse ...
... Massive PV integration will profoundly affect the power supply-demand dispatch scenario, such as the generator flexibility, dispatch of renewable production, and utilization of seasonal storage. This research presents a technical-economic assessments of a large-scale PV integration into grid with PHS balancing dispatch are presented, using real data of Kyushu, Japan. The impacts of PV integration ...
... Coastal tourism developed along the Valparaíso region of Chile is being threatened by a very particular issue: scenery degradation related to extreme urbanization and collateral effects. This paper presents the results of scenic evaluation of 96 sites along this region. The scenic evaluation assesses values from a checklist of 18 physical and 8 human parameters, and permits calculation of a scenic ...
... Currently, energy consumption reduction is playing a more and more important role in production and manufacturing, especially for energy-intensive industries. An optimal production scheduling can help reduce unnecessary energy consumption. This paper considers an identical parallel machine scheduling problem to minimize simultaneously two objectives: the total energy consumption (TEC) and the make ...
... In recent years, new planning tools have emerged to aid planners to achieve multiple goals to sustainability. The Green Factor tool has been adopted by some cities to increase the share and effectiveness of green areas. This short communication asks how useful the Green Factor tool is and how it fits with the existing planning procedures regarding green areas through a qualitative case study in th ...
... In this work, simultaneous scheduling and vessel routing problem of pipeless plants is addressed with different layouts of units/stations. A general framework is presented for optimization of pipeless plants, which includes guidelines for state-task-network development covering issues such as when to consider vessels as states and how to handle vessel routing. The proposed formulation has been ill ...
... In 2015, China’s national government initiated a Sponge City Programme to address its urban flood issues. A sponge city is a city built around the concept of managing water in an ecologically sustainable way. The intention is to improve urban resilience through rainwater capture, storage and use. This article applies a four-mode governance framework to analyze the programme. It identifies the stre ...
... This Editorial to the BESAFE special issue introduces the project and its approach and case studies. The BESAFE (EC 7th Framework programme) project investigated how the effectiveness of different types of arguments for biodiversity conservation depends on the context in which they are used. Our results show that tailoring of argumentation to audience within the course of decision processes is the ...

Abstract:
... Since the beginning of the New Millennium, increasingly widespread availability of the Internet and digitally enabled tools have made production processes more accessible to private individuals, introducing new opportunities for personal fabrication and social manufacturing. Yet scant sustainability research has been conducted on this important sector. We argue that research barriers, particularly ...
... Forensic Advisors at the National Institute for Criminalistics and Criminology in Brussels act as advising body to the magistrate regarding analytical possibilities and the usefulness of trace analysis in a case. Initially, their function was devised to assist in complex murder cases with unknown offender. However, in a previous study, the increasing diversity of the cases they are requested for h ...
... A considerable amount of energy is consumed by machine tools during the run-time operations such as tool change and tool path. The value of this part of energy is affected by the processing sequence of features of a part (PSFP) because the tool path and tool change plan will vary based on the different PSFP. This paper firstly aims to understand the relationship between the PSFP and the energy con ...
... In this paper, we propose a method to crowdsource the task of complex three-dimensional information extraction from 3D point clouds. We design web-based 3D micro tasks tailored to assess segmented LiDAR point clouds of urban trees and investigate the quality of the approach in an empirical user study. Our results for three different experiments with increasing complexity indicate that a single cro ...
... The question that still divides many debates about sustainability is the possibility of technological substitution of scarce natural resources. While there is considerable debate among economists whether technology can mitigate scarcities through development of substitutes, there is little actual research on the mechanisms and limitations of this substitution process. In this study, I seek to buil ...

Abstract:
... Abundance data are the foundation for many ecological and conservation projects, but are only available for a few taxonomic groups. In contrast, distribution records (georeferenced presence records) are more widely available. Here we examine whether year‐to‐year changes in numbers of distribution records, collated over a large spatial scale, can provide a measure of species' population variability ...
