University of Huelva posted this:Procedure for obtaining a renewable resource of metals from acid minewater, and the respective systemsIs known in the state of the art the recovery of metals from the acid aqueous solution that contain them, generally by liquid-liquid extractions. For metals recovery at industrial scale is necessary that these metals can be recovered simultaneously by means of a single extraction step. There are several extraction reagent for this purpose, all these reagent are very expensive and the industrial process for the metal recovery (particularly for rare earth and yttrium) are very complex and finally expensive. The present procedure allows to recovery selectively metals (particularly rare earths and yttrium) by the neutralization of acid mine waters. The objective is to revalue the metal content dissolved in this waters.
University of Huelva posted this:New method for manufacturing magnetic cores by powder metallurgyMagnetic cores in amorphous state are usually produced by placing together very thin amorphous ribbons from a material obtained by the melt-spinning technique. The new patented method produces the amorphous material by mechanical alloying, a traditional process in the powder metallurgy field. This technique allows a higher control on the amorphisation process and the properties of the amorphous obtained powders. These powders are then consolidated by the very quick process known as Electrical Resistance Sintering (also Electrical Discharge Consolidation/Sintering can be used). A final amorphous material, without the typical frontier between ribbons of melt spinned materials, which clearly affect properties, is obtained.

University of Huelva posted this:Measurement system for the identification and accurate determination of distorting loads in electrical networks and microgridsThe only measurement of distortion level in a network can highlight the need for action to control it. Among those actions is, for example, the use of power filters. However, the determination of the most suitable point where the filter must be connected and its most appropriate configuration requires further analysis of the micro-network (a subset of nodes in the network with different loads connected to each). Therefore, an additional study becomes necessary to establish the responsibility of each load in global distortion levels. In addition, the establishment of the model of the most responsible loads is also necessary in order to decide the filter configuration. In this sense, the load may be voltage distorting or current distorting. All this information is provided by the device of the invention. Indeed, the device, besides distributing the responsibility for overall levels of distortion between each agent, reports whether loads are voltage harmonics or current harmonic sources. This information is the most relevant to determining the power filter settings that best mitigate the distortion in each network node.
Fundació URV posted this:ELECTRE-H software package: a tool for data analysis and decision aiding with hierarchical criteriaThe ELECTRE-H Software Package implements two new methods for ranking and ordered classification decision problems considering multiple criteria structured into a hierarchy. The hierarchy of criteria is a tool that allows the decision maker to better organize the problem based on its domain knowledge and needs, decomposing the general problem into smaller sub-problems. Both methods follow the well-known outranking model and belong to the family of ELECTRE methods. The ELECTRE approach is inspired on the voting-like procedure based on the opinion of the majority but also respecting the minorities (by allowing veto power). The software available to use ELECTRE methods does not allow a hierarchical decomposition of the problem, but on a flat organization of criteria. The ELECTRE-H for hierarchical sets of criteria was defined by Dr. Del Vasto and Dr. Valls (from URV) and Dr. Slowinski and Dr. Zielniewicz (from Poznán University of Technology, Poland). The papers can be found here: http://www.sciencedirect.com/science/article/pii/S0957417415001153 http://link.springer.com/article/10.1007/s10844-015-0362-7 The novelties of these two methods are the following: -It fully applies the standard outranking procedure of ELECTRE at all the levels of the hierarchy of criteria (concordance and discordance indices are obtained from the results of the previous layer and exploited at each node to generate new results). -The user will get a result (a ranking or classification) at each intermediate node of the hierarchy as well as the root (or overall) node. -Preference uncertainty can be managed at each node of the hierarchy with its particular discrimination threshold values. -Veto power can be given to the appropriate nodes in the hierarchy, to avoid compensation with the rest of related criteria. -Different scales of measurement can be used both in the elementary criteria and in the intermediate criteria. -For the case of sorting, simple IF…THEN… decision rules are used to define the categories. The novelty of the software ELECTRE-H is that it is the implementation of these methods given by the authors. This guarantees that the program is fully following the methodology proposed. Its main features are: -Clear and easy-to-understand user interface. -Data can be easily provided using an Excel file. -All the parameters of the model can be easily changed in the user interface. -The results obtained can be graphically displayed (i.e. partial pre-orders, rankings) and exported into a PNG image or text files. Also, the calculations of the results are provided in log files. -Additional statistical tools to compute correlations for different ranking and classification results on the same set of alternatives and hierarchy are available. - A distance-based statistical tool to compare partial preorders is available. -The “Simos revised procedure” to calculate numerical values for criteria weights is available. -Analysis of the results can be done at different levels of the hierarchy. -The software supports large number of alternatives and criteria. Also the structure of the hierarchy is only limited to be a tree (each node has a single parent). The software is designed to be easy to use while providing the full functionality required in these two methods.
