  1. 1. Evaluation of quantification methods for inclusion distribution in clean steel

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Felicia Fröjd; [2019]
    Nyckelord :Large area scanning; high frequency ultrasonic testing; light optical evaluation; inclusion distribution;

    Sammanfattning : Ovako products are in many cases used in high fatigue applications. Currently Ovako use ultrasonic evaluation at 10 MHz as a volumetric method for inclusion control. This study intends to investigate two new methods for quantification of micro inclusions. LÄS MER

  3. 2. GENERAL WAKE-UP RADIO MODULE FOR ISM BAND

    Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Mohammed Ashiq Rahman Tajudeen; [2018]
    Nyckelord :;

    Sammanfattning : With the word of smart, the whole world is running on the smart technologies and smart devices which are fairly constructed by wireless sensors networks. The heart of the WSNs are nodes, which are deployed in different environmental conditions with different applications. LÄS MER

  4. 3. Development of a wideband high power amplifier for cancer treatment.

    Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Sohil Shahabi Ghahfarokhi; [2013]
    Nyckelord :wideband; high power; amplifier; hyperthermia;

    Sammanfattning : Medical hyperthermia refers to heating of tumors to temperature levels which are lethal to the cells for sufficient periods of time or rendering the cancerous cells more sensitive to ionizing radiation or chemotherapy. In order to increase the temperature in cancerous tissues, high power solid state microwave amplifiers need to be used. LÄS MER

  5. 4. BERT and FFT measurement systems for high-speed communications and magnetometry

    Master-uppsats, Institutionen för teknikvetenskaper

    Författare :Qiwei Zhu; [2011]
    Nyckelord :fpga; BERT; DSP; 8b10b;

    Sammanfattning : This master thesis presents the development and implementation of two digital systems based on Field-programmable Gate Array (FPGA): a Bit Error Rate Testing (BERT) system for an Optical Communication (OCOM) application, and a Digital Signal Processing (DSP) system for a Spin-Dependent Tunneling Magnetometer (SDTM). Both applications are intended for space and currently under development at the Ångström Space Technology Center (ÅSTC). LÄS MER

  7. 5. Hardware bidirectional real time motion estimator on a Xilinx Virtex II Pro FPGA

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Rashid Iqbal; [2006]
    Nyckelord :Bidirectional motion estimation; FPGA; Relationally placed macro; CLB; slice; tristate buffers; comparator; pipelining; search upper; search lower; VHDL; Xilinx; block matching; MeEngine; LMC; CMC.; sum of absolute differences; systolic array; SARow; PE2X8; MeProC; 125 MHz; Virtex II Pro;

    Sammanfattning : This thesis describes the implementation of a real-time, full search, 16x16 bidirectional motion estimation at 24 frames per second with the record performance of 155 Gop/s (1538 ops/pixel) at a high clock rate of 125 MHz. The core of bidirectional motion estimation uses close to 100% FPGA resources with 7 Gbit/s bandwidth to external memory. LÄS MER
