  1. 1. Optimization of battery pack assembly of second life cells to reduce costs

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Akash Prasad Chowdry; [2022]
    Keywords : Batteries; second life cells; active cell balancing; lossless cell balancing; off-grid solar; solar home systems; Batterier; second life cells; aktiv cellbalansering; förlustfri cellbalansering; solceller utanför nätet; solcellssystem för hemmabruk.;

    Abstract : Batteries account for 50% of the overall cost of solar home systems (SHS). The battery packs degrade over time and when they reach 70% state of health (SOH), the whole SHS is discarded. In the predominantly rural off-grid context, battery replacements are expensive and impractical. The customers are often dozens of km away from any sales point. READ MORE

  3. 2. Lossless Message Compression

    University essay from Akademin för innovation, design och teknik

    Author : Erik Hansson; Stefan Karlsson; [2013]
    Keywords : Compression; Message compression; Lossless compression; LINX; IPC; LZO; LZFX; LZW; LZMA; bzip2; LZ4; Effective throughput; Goodput;

    Abstract : In this thesis we investigated whether using compression when sending inter-process communication (IPC) messages can be beneficial or not. A literature study on lossless compression resulted in a compilation of algorithms and techniques. READ MORE

  4. 3. Improving compression ratio in backup

    University essay from Informationskodning; Tekniska högskolan

    Author : Mattias Zeidlitz; [2012]
    Keywords : Compression; image coding; lossless; transcoding; interfile; Kompression; komprimering; bildkodning; förlustfri; transcoding; interfil;

    Abstract : This report describes a master thesis performed at Degoo Backup AB in Stockholm, Sweden in the spring of 2012. The purpose was to design a compression suite in Java which aims to improve the compression ratio for file types assumed to be commonly used in a backup software. READ MORE

  5. 4. An Introduction and Evaluation of a Lossless Fuzzy Binary AND/OR Compressor

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Philip Baback Alipour; Muhammad Ali; [2010]
    Keywords : Fuzzy Binary AND OR; data compression decompression; pairwise bits; double efficiency;

    Abstract : We report a new lossless data compression algorithm (LDC) for implementing predictably-fixed compression values. The fuzzy binary and-or algorithm (FBAR), primarily aims to introduce a new model for regular and superdense coding in classical and quantum information theory. READ MORE
