  1. 1. Compression and Decompression of Color MRI Image by Huffman Coding

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Xin Zou; [2018]
    Nyckelord :;

    Sammanfattning : MRI image (Magnetic Resonance Imaging) as a universal body checkup method in modern medicine. It can help doctors to analyze the condition of patients as soon as possible. As the medical images, the MRI images have high quality and a large amount of data, which requires more transmission time and larger storage capacity. LÄS MER

  2. 2. Memory Energy Optimizations for IoT Processors

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

    Författare :Ricardo Gómez; [2016]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In battery operated devices, such as mobile phones, power consumption is an important constraint, as it has a direct impact on the battery lifetime. Trying to extend the battery lifetime as much as possible has been one of the major targets in device development for the past years. LÄS MER

  3. 3. Implementing Linear Predictive Coding based on a statistical model for LTE fronthaul

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

    Författare :Ghassan Nakkoul; Mohammad Shohag Hassan Kaikobad; [2016]
    Nyckelord :Entropy; LTE fronthaul; RRH; BBU; C-RAN; Quantization; LTE downlink; Cyclic prefix; LPC; EVM; OFDM; Linear predicting coding; LTE; Technology and Engineering;

    Sammanfattning : This thesis studies the application of Linear Predictive coding (LPC) in the downlink of Long Term Evolution (LTE) fronthaul, which comprises of BBU and RRH. This can act as an additional module in the existing system. Today, the transmission of a single complex sample from the BBU to the RRH consumes 30 bits. LÄS MER

  4. 4. ANDROID SECURE DEPLOYMENT & NFC BASED E-LIBRARY IMPLEMENTATION

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :FARRUKH HASSAN; [2015]
    Nyckelord :Cloud based Server; Attacks; Heterogeneous Networks; Authentication; RFID tags; NFC; Partial keys.;

    Sammanfattning : This thesis communicates a new approach for the future Library system using secure NFC technology. Today we can use NFC and Android based mobile phones to build modern library system in which user will instead of standing in the queue can directly borrow and return books. LÄS MER

  5. 5. Metodiskt backupsystem för lokalkontrollsutrustningar

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Kristian Ohlsson; [2013]
    Nyckelord :backup; PLC; huffman; zip; lagring; RAID; virtualisering;

    Sammanfattning : Statkraft är helägt av Norska staten och är Sveriges fjärde största elproducent. Detta examensarbete syftar till att ta fram en metod för att lösa hur Statkraft Sverige AB ska lagra mjukvarubackuper av sina lokalkontrollssystem. LÄS MER
