  1. 11. Return Rate Prediction

    University essay from Lunds universitet/Matematisk statistik

    Author : Erik Karlén; Caspar Welin; [2017]
    Keywords : Mathematics and Statistics;

    Abstract : Product quality is a major concern for all companies. Predicting the lifetime return rate allows for identification of products with atypically high return rates. Such products might otherwise not have been detected before it is too late to take any action to reduce the return rate. READ MORE

  3. 12. Enhanced dielectric AC breakdown strength of polyethylene using voltage stabilizing additives

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Klas Esbo; [2016]
    Keywords : cross-linked polyethylene; LDPE; low density polyethylene; polyethylene; voltage stabilizing additives; fast avalanche breakdown; dielectrical breakdown strength; High voltage cable; HVAC; XLPE; Weibull distribution; AC breakdown; materials chemistry; materialkemi; Technology and Engineering; Chemistry;

    Abstract : There is currently a need to increase the voltage level in high voltage transmission and distribution systems in order to transmit power in a more efficient way. However, the insulation of the conductor in high voltage alternating current (HVAC) cables needs to be improved in order to withstand these high voltages. READ MORE

  4. 13. Energy Storage System for Wind-Diesel Power System in Remote Locations

    University essay from Högskolan i Gävle/Energisystem

    Author : Roberto Cordeiro; [2016]
    Keywords : Energy Storage; Energy Storage System; Energy Storage Technology; ESS; Wind Diesel Power System; WDPS; Wind Turbine; Wind Penetration; Energy Systems Simulation; reMIND;

    Abstract : The aim of this thesis is to show how much fuel can be saved in a power system based in diesel generators with integrated wind turbine (WDPS – Wind Diesel Power System) when a storage system is integrated. Diesel generator is still the most used power system for remote locations where the conventional grid doesn’t reach and its integration with wind turbine is seen as a natural combination to reduce diesel consumption.

  5. 14. Survival analysis of gas turbine components

    University essay from Linköpings universitet/Statistik

    Author : Alessandro Olivi; [2016]
    Keywords : Bayesian Weibull regression; failure modes; optimal replacement time; reliability; survival analysis;

    Abstract : Survival analysis is applied on mechanical components installed in gas turbines. We use field experience data collected from repair inspection reports. These data are highly censored since the exact time-to-event is unknown. We only know that it lies before or after the repair inspection time. READ MORE

  6. 15. Energy flow in a Hybrid Wind/ Hydrogen System for Kampala and Tororo towns in Uganda

    University essay from KTH/Energiteknik

    Author : GODFREY SSAJJA SSALI; [2015]
    Keywords : ;

    Abstract : This report presents modeling for energy flow of a distributed renewable energy system based on an integrated wind power and hydrogen production system supplying a local electric load connected to an electric grid. The system consists of a 200kW wind generator, an Electrolyzer with a maximum production capacity of 5kg of hydrogen per 24h and a 3. READ MORE
