  1. 1. Mille-feuille Filter : A Non-woven Nano-cellulose Based Virus Removal Filter for Bioprocessing

    Författare :Simon Gustafsson; Albert Mihranyan; Jonas Lindh; Kurt Brorson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virus filtration; mille-feuille; downstream; nanocellulose; protein throughput; protein recovery; LRV; MVM; Cladophora; non-woven filter;

    Sammanfattning : Virus removal filters, produced from synthetic surface-modified polymers or regenerated cellulose by phase inversion, are vital to the production of therapeutic proteins such as monoclonal antibodies and plasma proteins. Use of these filters is also one of the most expensive purification steps in the downstream processing of proteins due to high sales price and being limited to a single use. LÄS MER

  3. 2. Distributed Signal Processing in Digital Substations : Integrating High Sampling Rate Measurements at the Process-Level

    Författare :Fabian Hohn; Lars Nordström; Peter Crossley; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Communication networks; digital signal processing; digital substation; field-programmable gate array; filter design; IEC 61850; IEC 61869; power system protection; substation automation; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Future power systems will be dominated by power electronic (PE) converter connected generation. This trend is primarily driven by the increasing penetration of wind power as well as the increasing integration of photovoltaic (PV) based generation. LÄS MER

  4. 3. On low-complexity frequency selective digital filters and filter banks

    Författare :Linnea Rosenbaum; Håkan Johansson; Tapio Saramäki; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital filters; filter banks; modulated; FRM; Electronics; Elektronik;

    Sammanfattning : En filterbank består av flera filter som arbetar tillsammans för att dela upp en signal i olika frekvensband. De kan också användas för att slå ihop signaler separerade i frekvensplanet till en enda. Sedan tidigt 70-tal har man lärt sig att designa förlustfria filterbankar som alltså inte introducerar några som helst fel i systemet. LÄS MER

  5. 4. Filter bank design for digital speech signal processing : methods and applications

    Författare :Jan Mark de Haan; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive filter theory; Subband filter banks;

    Sammanfattning : Adaptive filter theory is an important subject in the field of signal processing and has numerous applications in speech processing, telecommunications and mechanical engineering. Examples in speech processing include suppression of background noise, echo cancellation and dereverberation (acoustic path equalization). LÄS MER

  7. 5. Custom Datapaths for DSP ASICs Methodology and Implementation

    Författare :Pontus Åström; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; handshake circuits; design patterns; design abstraction; design methodology; UMTS; interleaver architecture; Turbo decoder implementation; low power; Digital filter; wave digital filter;

    Sammanfattning : This thesis regards datapath design and analysis at several abstraction levels. Five papers are presented that focus on datapath design for mobile communication systems and design methodologies for such datapaths. Paper I discusses different aspects of Turbo channel decoder design for high speed and low power applications. LÄS MER
