  3. 3. Packet Order Matters! : Improving Application Performance by Deliberately Delaying Packets

    Författare :Hamid Ghasemirahni; Dejan Kostic; Alan L. Davis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Packet Ordering. Spatial Locality; Temporal Locality; Packet Scheduling; Batch Processing; Paketbeställning; Rumslig lokalitet; Temporal lokalitet; Paketplanering; Satsvis bearbetning; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Data-centers increasingly deploy commodity servers with high-speed network interfaces to enable low-latency communication. However, achieving low latency at high data rates crucially depends on how the incoming traffic interacts with the system's caches. When packets that need to be processed in the same way are consecutive, i.e. LÄS MER

  4. 4. Cognition in Hearing Aid Users : Memory for Everyday Speech

    Författare :Hoi Ning Elaine Ng; Jerker Rönnberg; Mary Rudner; Thomas Lunner; Kevin Munro; Linköpings universitet; []
    Nyckelord :Hearing aid; working memory; free recall; noise reduction; speech recognition; Hörapparat; arbetsminne; återgivning; brusreducering; taluppfattning;

    Sammanfattning : The thesis investigated the importance of cognition for speech understanding in experienced and new hearing aid users. The aims were 1) to develop a cognitive test (Sentence-final Word Identification and Recall, or SWIR test) to measure the effects of a noise reduction algorithm on processing of highly intelligible speech (everyday sentences); 2) to investigate, using the SWIR test, whether hearing aid signal processing would affect memory for heard speech in experienced hearing aid users; 3) to test whether the effects of signal processing on the ability to recall speech would interact with background noise and individual differences in working memory capacity; 4) to explore the potential clinical application of the SWIR test; and 5) to examine the relationship between cognition and speech recognition in noise in new users over the first six months of hearing aid use.

  5. 5. The art of transcriptome reconstruction : with applications in Picea abies (L.) H. Karst

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transcriptome reconstruction; transcriptome assembly; transcript isoform detection; Picea abies; acrocona; cone setting; differential expression; gene families; miRNA; quality assessment; transkriptomrekonstruktion; sammansättning av transkriptom; detektering av transkriptisoform; rödgran; kottegran; kottsättning; differentiellt uttryck; genfamiljer; kvalitetsutvärdering; miRNA; Biotechnology; Bioteknologi;

    Sammanfattning : Transcriptome reconstruction is an important component in the bioinformatical part of transcriptome studies. When a reference genome is missing, highly fragmented or incomplete, a de novo transcriptome assembly is the transcriptome reconstruction approach of choice, since in such situations, a simple alignment (or mapping) would not necessarily give all theinformation concerning splice junctions, isoforms or even the full extent of the gene.
