  1. 21. Development of a wear index and its methodology related to mineral processing - Part I

    University essay from Lunds universitet/Industriell Produktion

    Author : André Larsson; [2016]
    Keywords : Nanoindentation; Berkovich indenter; wear; surface hardness; rock; minerals; manganese steel; mining; comminution.; Technology and Engineering;

    Abstract : This Master Thesis was performed for Sandvik SRP in collaboration with the Institution for Industrial Production Faculty of Engineering at Lund University. Tool wear is one of the main cost drivers in the mining industry. READ MORE

  3. 22. 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. 23. 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. 24. 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. 25. Graphical Editor for Graphical User Interfaces for an "Internet of Things" System

    University essay from Lunds universitet/Institutionen för datavetenskap

    Author : Gunnar Weibull; [2015]
    Keywords : Graphical Editor; Graphical User Interface; GUI; PalCom; Internet of Things; Technology and Engineering;

    Abstract : The aim for the graphical editor described in this paper is to simplify the creation of Graphical User Interfaces (GUIs) for PalCom (an “Internet of Things”-solution). Ideally, the people who are to use the GUIs will be able to create them themselves. Most graphical editors focus on placing graphical components (buttons etc. READ MORE
