  1. 1. Analysis of Positional Precision when Using Ground Control Points with Supported INS in GNSS-Free Environments

    University essay from KTH/Fastigheter och byggande

    Author : Linus Bäckström; Patrik Grenert; [2021]
    Keywords : Track maintenance; GNSS; INS; GCP; GNSS-free environments; Railway positioning; Rälsunderhåll; GNSS; INS; Kända punkter; Avsaknad av GNSS; Positionering på räls;

    Abstract : Railway traffic is one of the most used transportation methods in today's society both for freight transports and transportation of people. A necessity for this to function is that the tracks upon which the trains travel are functional. READ MORE

  2. 2. Data interpolation for groundwater modelling : How choice of interpolation method and sample size affect the modelling results

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Frida Agerberg; [2020]
    Keywords : Geohydrology; Groundwater; Modelling; Interpolation; SEEP W; Surfer; Geohydrologi; Grundvatten; Modellering; Interpolering; SEEP W; Surfer;

    Abstract : Over the past several decades, the use of groundwater modelling has been increasing in order to better evaluate the complexities inherent in hydrogeological calculations. Information required for groundwater modelling is for example elevation of soil and bedrock layers, which often is collected by drilling. READ MORE

  3. 3. The Information Bottleneck : Connections to Other Problems, Learning and Exploration of the IB Curve

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Borja Rodriguez Galvez; [2019]
    Keywords : ;

    Abstract : In this thesis we study the information bottleneck (IB) method. This is an informationtheoretic framework which addresses the question of what are the relevant factors of arandom variable X to explain another statistically dependent random variable Y . Thesefactors are embedded into a bottleneck variable T obeying the Markov condition Y $X $ T. READ MORE

  4. 4. Security Assessment of the French Transmission System Using Multi-Situation Methods

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Louis Garnier; [2018]
    Keywords : ;

    Abstract : Traditionally, the main sources of electricity production in the power system have beenconventional power plants (using either nuclear fuel, coal, gas or oil). The power istransferred by the transmission system to the cities, where the distribution system ensures thelink to the consumers. READ MORE

  5. 5. On long-range and high frequency propagation alongparallel strip conductors in layered media : A simplified yet accurate method using the mode matching technique in the spectral domain

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Benjamin Oakes; [2013]
    Keywords : ;

    Abstract : Electrical arcing in the railway environment radiates wideband noise that can disturb nearbysensitive electronics e.g. signaling systems. High frequency disturbances follow conducting wiresand rails. READ MORE
