  • London’s reliance on diesel triggers re-emergence of an old enemy: smog

    It’s Christmastime on Oxford Street. Brilliant displays of white lights rain from above. Decked-out shoppers dash from one gaudy sale to the next. And Johnny Conquest breathes in poison. “The air is horrible. The taxis stop right here, and when they take off, boom, you can taste it,” says the 67-year-old as the heavenly smell of the caramel peanuts he hawks from a humble street ...

  • Hybrid wavelet-support vector machine approach for modelling rainfall–runoff process

    Because of the importance of water resources management, the need for accurate modeling of the rainfall–runoff process has rapidly grown in the past decades. Recently, the support vector machine (SVM) approach has been used by hydrologists for rainfall–runoff modeling and the other fields of hydrology. Similar to the other artificial intelligence models, such as artificial neural network (ANN) ...

  • Hybrid System in Fiji: The Sun Saves Fuel

    When you think of Fiji, you first think of vacation, wonderful beaches with palms and crystal clear water with perfect spots for scuba diving. We also thought of energy: Energy that could help build a more ecological electrical power supply. The existing power supply on the three separate islands of Kadavu, Lakeda and Rotuma around the Fijian mainland had been fully based on diesel generators. ...

  • The effects of bupropion on hybrid striped bass brain chemistry and predatory behavior

    Increased use of antidepressants has led to an increase in their detection in final treated wastewater effluents and receiving streams. Antidepressants are intended to modify human behavior by altering brain chemistry, and due to the high functional conservation of the receptor targets of antidepressant target receptors in vertebrates, aquatic organisms may be at risk. The antidepressant ...

  • A hybrid MILP-LP-LP approach for the optimal design and operation of unconfined groundwater utilization systems

    This paper proposes a hybrid mixed-integer linear programming-linear programming-linear programming (MILP-LP-LP) methodology for simultaneous optimal design and operation of unconfined groundwater utilization systems. The proposed model is an extension to the earlier LP-LP model introduced by the authors for the optimal design and operation of confined groundwater utilization systems. The ...

  • Adsorption of azo dyes from aqueous solution by the hybrid MOFs/GO

    In this work, a hybrid of chromium(III) terephthalate metal organic framework (MIL-101) and graphene oxide (GO) was synthesized and its performance in the removal of azo dyes (Amaranth, Sunset Yellow, and Carmine) from water was evaluated. The adsorption for azo dyes on MIL-101/GO was compared with that of MIL-101, and it was found that the addition of GO enhanced the stability of MIL-101 in ...

  • A hybrid cuckoo–harmony search algorithm for optimal design of water distribution systems

    Meta-heuristic algorithms have been broadly used to deal with a range of water resources optimization problems over the past decades. One issue that exists in the use of these algorithms is the requirement of large computational resources, especially when handling real-world problems. To overcome this challenge, this paper develops a hybrid optimization method, the so-called CSHS, in which a ...

  • Hybrid wavelet-GMDH model to forecast significant wave height

    In this study, the group method of data handling (GMDH)-based wavelet transform (WT) was developed to forecast significant wave height (SWH) in different lead times. The SWH dataset was collected from a buoy station located in the North Atlantic Ocean. For this purpose, the time series of SWH was decomposed into some subseries using WT and then decomposed time series were imported to the GMDH ...

  • Fluoride removal by a hybrid fluoride-selective adsorbent

    High concentrations of fluoride in groundwater have become a global environmental challenge. Out of the various methods developed for effective removal of fluoride adsorption using activated alumina (AA) is popular as it has a low initial cost. AA offers excellent chemical and mechanical stability, selectivity for fluoride, favorable hydraulic properties, regenerability but offers lower ...

  • Indian Wind Power Industry 2014 Analysis

    This latest market research report titled Wind Power Market in India 2014 analyses how the renewable energy sector is gaining importance in India and how wind energy has become an indispensable part of this sector. With the gap in demand and supply of energy increasing at a steady pace, it has become necessary to look beyond conventional sources for generating energy. This has led to a shift in ...


  • Hybrid machine intelligence–based improved classifiers for multiple power signal disturbances

    This work presents a new technique for the identification of multiple power quality disturbances in industrial power systems. This new technique is developed based on change detection filter (CDF) and machine intelligence techniques like the local linear radial basis function neural network (LLRBFNN) and decision tree (DT). The proposed change detection filter has been designed in one cycle back ...

  • A new time–frequency approach for hybrid differential and impedance protection of transmission lines

    A new current differential protection of transmission lines is presented in this paper using an S–transform variant having very fast computational speed suitable for real–time applications. The conventional S–transform used earlier for transmission line protection has large computational overhead and thus is not suitable for generating decisions regarding the occurrence of a fault and its type on ...

  • Optimal sizing of a hybrid energy system for a semi-arid climate using an evolutionary algorithm

    The use of a genetic algorithm (GA) for optimal sizing of an off-grid hybrid renewable energy system (HRES) is reported. As a pre-feasibility analysis and to determine the appropriate HRES type to be studied, wind energy potential and solar irradiation are first examined for the considered region (Tehran, Iran). These are inputs of the algorithm, and are assessed throughout a year utilising ...

  • A new hybrid algorithm for rainfall–runoff process modeling based on the wavelet transform and genetic fuzzy system

    In this paper, two hybrid artificial intelligence (AI) based models were introduced for rainfall–runoff modeling. In the first model, a genetic fuzzy system (GFS) was developed and evolved for the prediction of watersheds' runoff one time step ahead. In the second model, the wavelet-GFS (WGFS) model, wavelet transform was also used as a data pre-processing method prior to GFS ...

  • Flow prediction in vegetative channel using hybrid artificial neural network approach

    Channel flow–vegetation interaction has been extensively studied in the past few decades and many equations have been developed which essentially differ from each other in derivation and form. As the process is extremely complex, getting deterministic or analytical forms of process phenomena are too difficult. A hybrid neural network model (combining genetic algorithm with neural ...

  • Hybrid powertrain for light aircraft

    In this paper, we evaluate the possibility of employing a hybrid powertrain to propel a light aircraft. The work suggests that the incorporation of a hybrid powertrain has little effect on fuel consumption for a light aircraft operating in a condition of straight and level cruise. However, there is a potential decrease in fuel consumption when a light aircraft operates either in climb or when ...
