  1. 11. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Eduardo Garcia Cañas; [2022]
    Keywords : HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

    Abstract : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. READ MORE

  3. 12. Niobium Ohmic Contacts for Cryogenic Indium Phosphide High-Electron-Mobility Transistors

    University essay from KTH/Tillämpad fysik

    Author : Linnéa Bendrot; [2022]
    Keywords : Ohmic contacts; high-electron-mobility transistor; InP; Nb films; cryogenic electronics; low-noise amplifier; quantum computing; transfer length method; superconductivity; contact barrier resistance; Ohmska kontakter; högelektronmobilitetstransistorer; indiumfosfid; niob; tunnfilm; kryogen elektronik; lågbrusförstärkare; kvantdatorer; Transfer Length-metod; supraledning; kontakt- barriärresistans;

    Abstract : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. READ MORE

  4. 13. Design of 3D-Printed Components : Resistances, Strain Gauges and Touch sensors

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

    Abstract : Additive manufacturing has recently become an increasingly available, affordable, and versatile technology for industry and enthusiasts alike. One opportunity that this provides is using conductive filament to print electronic sensors and components. READ MORE

  5. 14. Developing data processing program for a new radio magnetotelluric (RMT) instrument

    University essay from Uppsala universitet/Geofysik

    Author : Elis Uebel; [2022]
    Keywords : RMT radio magnetotellurics matlab GUI;

    Abstract : The radio magnetotellucic (RMT) method originates from (Tikhonov, 1950) and (Cagniard,1953) who discovered the possibility to estimate resistivity in the Earth’s subsurface using naturally occurring telluric currents. This through measuring the surface impedance of electromagnetic waves. READ MORE

  6. 15. 3D Geological Modelling of the Subsurface Adjacent to Cementa’s Quarry in Skövde, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Minna Larsson; [2022]
    Keywords : 3D model; limestone; cement production; resistivity; photogrammetry; Skövde; 3D modell; kalksten; cementproduktion; resistivitet; fotogrammetri; Skövde;

    Abstract : Limestone is one of the main components of cement production. Limestone has been quarried in Skövde, Sweden, since the end of 19th century and Cementa AB has been operating the quarry since 1973. Aside from limestone, there are also Alum shale of Cambrian age, mudstones as well as bentonite layers of Ordovician age present in the quarry. READ MORE
