  1. 1. Microelectronics for the thumb-size ultrasound measurement system

    Författare :Jonny Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : This thesis presents building blocks and strategies to reach the goal of a thumb-size autonomous ultrasound measurement system with wireless communication capabilities. The design of modern electronics is based on the possibility to accurately predict system behavior by the use of simulation tools. LÄS MER

  3. 2. SPICE modeling of ultrasound systems : improvements and verifications

    Författare :Jonny Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : The success of modern electronics is built on the possibility to accurately predict system behavior by the use of simulation tools. This paradigm can be extended to components such as sensors attached to the electronics. LÄS MER

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Media and communication studies; Medie- och kommunikationsvetenskap;

    Sammanfattning : Andelen affärstransaktioner som bedrivs på distans, dvs. handel där köpare och säljare inte träffas öga mot öga, blir allt större. LÄS MER

  5. 4. Mellan massan och Marx : en studie av den politiska kampen inom fackföreningsrörelsen i Hofors 1917-1946

    Författare :Stefan Dalin; Jonny Hjelm; Alf Johansson; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; the local council of the Social Democratic Party; socialists; social democrats; left-wing social democrats; the Labour Movement; working class; Comintern; The Swedish Metal Workers’ Union; The Swedish Trade Union Confederation; radicalism; local trade union environment; 20th century; norms; political culture.; trade union; communists; Hofors; History; Historia;

    Sammanfattning : The thesis concentrates on Hofors and a local trade union environment between 1917 and 1946, where important parts of the trade union’s power were held by parties to the left of the social democrats. The overall aim is to problemize and discuss the issue of what characterised and made possible this deviation from the usual picture of a trade union movement dominated by social democracy. LÄS MER

  7. 5. Robust energy management for IoT machine elements

    Författare :Fredrik Häggström; Jerker Delsing; Jonny Johansson; Saul Rodriguez; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy harvesting; Rolling element bearing; Energy Storage; Industrial Electronics; Industriell elektronik;

    Sammanfattning : Advancements in semiconductor technology have reached the point at which ambient energy in the surrounding environment can power sensors and microprocessors. This capability enables new strategies for energy management, which are necessary to continue the sensorization of our environment. LÄS MER
