  1. 1. Characterization of an ADC

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Carl-Fredrik Tengberg; [2017]
    Nyckelord :;

    Sammanfattning : Analog-to-Digital converters, ADCs, introduces the possibility of performing digital computation on real world analog signals by being the interface between thetwo domains. The demands on the performance of the ADC is steadily increasing, which also comes with an increased difficulty of actually being able to guarantee the functionality of the device. LÄS MER

  3. 2. Low Power Current Sensing Node Powered by Harvested Stray Electric Field Energy

    M1-uppsats, Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

    Författare :Björn Holby; Carl-Fredrik Tengberg; [2015]
    Nyckelord :Energy Harvesting; Low Power; Sensor; Wireless Communication;

    Sammanfattning : In this thesis, the possibility of harvesting energy from a multicore power cableconnected to a power outlet is presented and evaluated. By surrounding a powercable with a conductive material connected to ground, it is shown that the dif-ference in potential between the power cable and the conductive material causesa capacitance which can charge a capacitor that in combination with an energymanagement circuit can be used to wirelessly transmit data with an interval de-pending on factors like the length of the surrounding material and the type ofcable it is placed around.

  4. 3. Prestationsavgift i onödan?

    Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Fredrik Ekelund; John Tengberg; [2011]
    Nyckelord :Riskjusterad avkastning; fondavgift; prestationsavgift; aktiefonder; hedgefonder; Business and Economics;

    Sammanfattning : Uppsatsen syfte är att undersöka huruvida det går att finna ett samband mellan fonder med eller utan prestationsavgift och deras riskjusterade avkastning. Detta för att undersöka om prestationsavgift som incitament till förvaltare faktiskt fungerar. LÄS MER

  5. 4. En jämförelse av sitkagranens (Picea sitchensis) och den vanliga granens (P. abies) produktion

    L3-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Fredrik Tengberg; [2005]
    Nyckelord :Picea sitchensis; sitkagran; Picea abies; volymproduktion; odlingsegenskaper; ProdMod;

    Sammanfattning : Sitka spruce (Picea sitchensis) is a tree species that have its natural distribution along the West Coast of North America, from Alaska in the north to northern California in the south. Sitka spruce is a typical coastal tree species that can reach heights up to 85 meters and occurs in single pure as well as in mixed stands. LÄS MER
