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.Fundació URV posted this:

Electrically small antenna arrays for wireless communicationsA fundamentally novel method to significantly improve return loss and radiation efficiency of closely spaced antenna elements is experimentally demonstrated and explained using electromagnetic principles. This method is based on the use of a new electromagnetic material that strongly modifies antennae mutual coupling. The design can be scaled in frequency from 1GHz up to 60GHz. A 7-element prototype of an electrically small monopole antenna array operating around 2.4GHz with footprint dimensions less than λ/2x λ/2, λ is a wavelength of radiation, will be submitted as a part of solution. The developed concept of electrically small antenna arrays with enhanced radiation efficiency and improved return loss (antenna matching) can be applied in various wireless communication scenarios, including electrically compact MIMO terminals, reconfigurable smart antennas, accurate direction-of-arrival estimation, small antenna terminals for the wireless-enabled Internet-of-Things devices and antenna diversity applications. A simple yet robust beam forming algorithm requiring minimal signal processing will be also provided for the interested party.

Electrochemical battery for a sustainable circular model based on recyclable electrodesIMDEA Energy has developed a concept of a battery assembled with semi-solid injectable electrodes to facilitate the recycling of active materials and reuse the passive battery components. The battery is characterized by electrodes that are injected as a semi-solid material that enable direct recovery of active materials by dejection of the flowable electrodes from the cell. In conventional batteries crushing is needed for an adequate recycling process. However, the advanced injectable concept allows a practical reuse of all the passive components and a simple replacing process of the electrode materials.

Electrochemical biosensor for detection and quantification of alkylphenolsFast, efficient and accurate method for the quantification of alkylphenols (APs). These sensors are based on a network of single-walled carbon nanotubes functionalized with a highly specific anti-AP antibody, which is at the core of the AP quantification reaction. This quantification is determined as a function of the changes in the electrical current, which varied according not only to the presence of absence of these com-pounds, but also in proportion to their concentration.

Electrochemical system for CO2 reduction, hydrogen gas production, and treatment of ammonia wasteBackground Many industries, water and wastewater treatment plants, farmers, etc., produce large amounts of ammonia as a waste product. The most common approach to treat N-waste in wastewater treatment is to convert ammonium (NH4+) to nitrogen gas (N2) using such techniques as biological treatment, wet oxidation, and breakpoint chlorination. In particular, ammonia by-product of anaerobic digestion of nitrogenous organic wastes and wastewater can be converted to ammonium sulphate via reaction with sulphuric acid, which can be used as a source of fertilizer. However high sulphur content fertilizers can have harmful environmental effects (eg. soil acidification) which are restricted in many municipalities. Using nitric acid instead to produce an ammonium nitrate salt fertilizer product is a viable alternative however the price of nitric acid is 3-4 times higher than that of sulphuric acid and thus is not economically feasible.

Electrokinetic device and procedure for consolidation of porous materialsThe pores in the porous materials used in construction play an important role in the load-bearing capacity of a material because the higher porosity of a material usually generates a decrease in their mechanical properties. Furthermore, the porosity plays an important role in the durability of the materials, particularly the accessible porosity, because through these pores the alteration agents such as water and soluble salts can enter into a material. For many years there are several commercial consolidants that try to increase the cohesion between the mineral grains presented in the porous structures that are altered, trying to fill the pores presented within the material and in consequence trying to reduce the accesible porosity.

Electronic payment system by presenceThe technology developed by the researchers consists of an automated payment system, in which neither the user nor the collector needs to intervene. The transaction occurs only through the physical presence of the user at the site. The system is based on the use of an APP installed on mobile devices and the sensorization of the control area to detect the presence of users. This system can be very useful for transactions that are carried out periodically or in places where congregate a large agglomeration of people and it is necessary to speed up the payment process.

Elimination of blade tip vortices of aircraft propellersTECHNOLOGY/PRODUCT OVERVIEW Blade tip vortex is a powerful phenomenon that develops very quickly. However, ‘widening’ the blade tips increases the possibility of greater power and performance, at the same time, the vortex losses generated at the blade tips increase drastically. The solution currently used to reduce the vortices of the blade tips is reducing the angle of attack close to the blade tip. This is how it tries to avoid significant losses. At the same time, naturally, the drag force or the transmittable power decreases. Eliminating or reducing blade tip losses (eliminating vortices around the blade tip) means significant fuel savings and increased lifespan, efficiency, and performance especially when using wide blade tips. The elimination of blade tip loss reduces vibrations, thus reducing internal friction of the structure’s material, thereby increasing lifespan. This results in significant financial savings, e.g. in the case of a modern blade. Due to centrifugal force, the “winglet” used on wings moving in a linear direction cannot be used in the case of a rotating system.
