  1. 1. Evaluation of Discrete-Time Wideband Receivers for NB-IoT

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Magnus Wasting; [2021]
    Nyckelord :Discrete; time; filter; NB-IoT; Charge; Sharing; CMOS; Technology and Engineering;

    Sammanfattning : A receiver that covers several RF bands requires multiple front-end filters which increases the cost in terms of components and/or board/silicon area. Front-end filters assist a receiver to withstand interference at multiples of its down-conversion frequency. LÄS MER

  3. 2. Power and Energy Quality Optimization of a Battery Validation Facility : A case study of mapping the power profile of a battery cell testing facility

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Joakim Wahlund; [2020]
    Nyckelord :;

    Sammanfattning : With Northvolt’s aggressive plan to establishEurope’s largest battery factory in northern Sweden, the needto build a pilot plant to demonstrate the possibilities of thecompany was needed. Quality, performance and cycle-life arekey factors customers value particularly high when purchasingbatteries, thus, a need for validating these parameters emerges. LÄS MER

  4. 3. A Linear, Wide-band, Low-Power Receiver for Narrowband- Internet of Things (NB-IoT)

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Rohan Raghunath; Ghanashyam Ravindranath Prabhu; [2018]
    Nyckelord :NB-IoT; FTNC; Harmonic rejection; N-path filtering; RX Front End; Low power; Wide-band; Passive mixer; Current mode; Technology and Engineering;

    Sammanfattning : Advancement of technology with the aid of new application, wireless communication has grown rapidly in the past two decades. Recently, in the wireless communication industry, Narrowband- Internet of Things (NB-IoT) is being discussed by everyone, as the most important emerging technology of the day. LÄS MER

  5. 4. Charcoal Kiln Detection from LiDAR-derived Digital Elevation Models Combining Morphometric Classification and Image Processing Techniques

    Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS

    Författare :Vaidutis Zutautas; [2017]
    Nyckelord :charcoal kilns; automatic feature extraction; LiDAR; morphometric classification; Hough Circle transfer; medžio anglies krosnis; automatinis objektų išgavimas; LiDAR; morformetrinė klasifikacija; Hough apskritimo transformacija; kolbottnar efter resmila; automatisk funktion extraktion; LiDAR; morfometrisk klassificering; Hough Circle överföring;

    Sammanfattning : This paper describes a unique method for the semi-automatic detection of historic charcoal production sites in LiDAR-derived digital elevation models. Intensified iron production in the early 17th century has remarkably influenced ways of how the land in Sweden was managed. LÄS MER

  7. 5. Mitigation of Background Harmonic Amplification at PCC Using Active Filtering of STATCOM

    Master-uppsats, KTH/Elkraftteknik

    Författare :Luai Malki; [2017]
    Nyckelord :FACTS; Hybrid-STATCOM; TSC; TSR; VSC; passive filter; active filter; PWM; MMC; passivity; input admittance; resonance; harmonics; ABB;

    Sammanfattning : Shunt compensation devices have been a powerful candidate for expanding the limits of transmission facilities, allowing more active power transport and supporting voltage and overall stability of the network. An example of such devices is the Static Synchronous Compensator (STATCOM) which is based on Voltage Source Converter (VSC) which synthesizes output voltage and current for mainly reactive power compensation.
