In this article, we present a new clustering algorithm for Person Name Disambiguation in web search results. The algorithm groups web results according to the individuals they refer to. The best state‐of‐the‐art approaches require training data in order to learn thresholds for deciding when to group the webpages. However, the ambiguity level of person names on the web could not be previously estimated and the results of those methods strongly depend on the thresholds obtained with the training collections. ...

In this article, we present a new algorithm for clustering a bilingual collection of comparable news items in groups of specific topics. Our hypothesis is that named entities ( NE s) are more informative than other features in the news when clustering fine grained topics. The algorithm does not need as input any information related to the number of clusters, and carries out the clustering only based on information regarding the shared named entities of the news items. This proposal is evaluated using ...

This paper proposes an innovative desalination technology for sustainable off-grid systems taking advantage of complementary features of tidal range and solar PhotoVoltaic (PV) energies. According to the literature survey, this proposal has not been considered before. Since fresh water production can be easily stored, the key issue in designing SeaWater Reverse Osmosis (SWRO) desalination plants is to minimise the capital cost required per m3 of fresh water produced throughout the plant lifetime. ...

The ideal gas model with temperature-independent heat capacities is the most widely used thermodynamic model in gas turbine cycle simulations. This model is sometimes known as the “perfect gas model”. Closed analytical expressions for specific works and temperatures of the cycle are obtained in this way. If the results are accurate enough then the perfect gas model becomes a powerful analysis tool because its simplicity. For this reason it is the usually chosen option when energy, exergy or thermoeconomic ...

This paper deals with the design recommendations for solar reverse osmosis (RO) desalination based on solar organic Rankine cycles (SORC). This technology can be the most energy-efficient technology for seawater and brackish water desalination within the small to medium power output range (up to 500 kW) of the power cycle if the system is properly designed. However, theoretical studies, design proposals and experimental works are very scarce and only very few solar reverse osmosis systems driven by ...

Small single-pass desalination seawater Reverse Osmosis (SWRO) plants may be a solution to freshwater demand in North African countries. In the plant design, the selection of commercial SWRO membranes plays an important role in efficiency, according to the feed and product water qualities. Although the SWRO specific energy consumption has been the main parameter employed to describe the SWRO performance, other parameters such as the salt and boron rejection are of major importance. Therefore, this ...

Solar thermal driven reverse osmosis desalination is a promising renewable energy-driven desalination technology. A joint use of the solar thermal powered organic Rankine cycle (ORC) and the desalination technology of less energy consumption, reverse osmosis (RO), makes this combination interesting in some scarce water resource scenarios. However, prior to any practical experience with any new process, a comprehensive and rigorous theoretical study must be done in order to assess the performance of ...

In this paper, the coupling between the low-temperature solar organic Rankine cycle (ORC) and seawater and brackish water reverse osmosis desalination units has been carried out. Four substances have been considered as working fluids of the solar cycle (butane, isopentane, R245fa and R245ca). With these four fluids the volumetric flow of fresh water produced per unit of aperture area of stationary solar collector has been calculated. The former has been made with the optimized direct vapour generation ( ...

In a previous paper the authors analyzed a low power (100 kW) solar organic Rankine cycle (ORC) as the mechanical and thermal energy source for desalination processes. Such a solar ORC is powered by parabolic trough collectors with direct vapor generation (DVG) technology. To this day, however, there are still no commercial implementations of said technology. For this reason, in this paper we analyze a solar ORC configured to use thermal oil as heat transfer fluid (HTF) instead, a technology which may ...

This paper deals with the application of parabolic trough solar collectors to a double cascade of organic Rankine cycles for reverse osmosis desalination. Two different solar collectors are operated either with thermal oil or with the organic fluid of the top cycle. The solar thermal system drives a seawater reverse osmosis system with around 1000 m3/d of fresh water production if a thermal energy backup is available. Isopentane is selected for the low temperature cycle from a set of working fluids ...

However, some devices have not been treated as metal hydride-based systems or the pumping subsystems of solar thermal-driven reverse osmosis desalination systems. Following the typical classification given in the previous literature, in this work an update of the solar heat engines for water pumping based in thermodynamic methods (conventional and unconventional) is presented.

Experience in combining solar thermal and seawater or brackish water reverse osmosis (RO) desalination technologies is very limited. Two SOFRETES systems were in operation in the early 1980s for brackish water desalination. Only such two implementations involving a single design can be cited, along with a reduced number of theoretical analyses and design proposals. Nevertheless, since RO is the most cost-effective desalination technology and its energy requirements are low, solar thermal-driven reverse ...

This paper presents a preliminary design for a solar thermal-powered reverse osmosis desalination system. The high pressure pump in the seawater reverse osmosis unit requires a 95-kW input, while the reject energy is recovered by way of pressure exchangers. The unit's specific energy consumption is 6.48 MJ/m3 (1.8 kWh/m3) for a recovery rate close to 50% and a feed pressure of 5.53 MPa. The unit was coupled to a solar power cycle based on a Rankine cycle with toluene, hexamethyldisiloxane (MM) and ...

A study of optical properties of Nd3+ doped oxyfluoride glasses and glass ceramics prepared by three different methods has been carried out. These methods start from NdF3, Nd2O3, or a Nd3+ ion solution as doping agent. The alternative preparation method based on a preliminary dissolution of the Nd3+ ions is proposed in order to avoid nonhomogeneous dopant distribution and spontaneous devitrification during glass elaboration. In the frame of the Judd–Ofelt theory, main radiative parameters have been ...

We have focused on making lighter the processing of comparing company profiles with tweets in order to obtain a competitive real-time system. With this aim, we only use the home page of each company as information source to create a unique profile. On the other hand, we compute the similarity of a tweet in connection to a profile by comparing the content of the tweet with the profile. Both steps do not ...

However, the singularities of small isolated power systems in terms of the high dependence of fossil fuel-based generation and the relative short distances travelled do require a particular analysis to evaluate the potential emission reduction. This paper describes a simulation study for estimating the energy consumption and the corresponding Well-to-Wheels GHG emissions of different light-duty ...

This problem has been addressed in a monolingual scenario where all the search results are written in the same language.
