  1. 11. Wirelessly Powered Communications: From Signal Optimization to Antenna Design

    Författare :Boules Atef Nessim Mouris; Ragnar Thobaben; Aggelos Bletsas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless power transfer; multi-tone signals; non-linear energy harvester; wirelessly powered sensors; joint source-channel coding; analog mappings; energy scheduling; mutual coupling reduction; electromagnetic bandgap; glide symmetry.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Future internet-of-things (IoT) and beyond 5G communication systems are envisioned to offer large-scale wireless connectivity where the different components of life, society and industry are connected in a smart yet sustainable way. The need for continuous battery charging and/or replacement is a bottleneck for sustainability in these systems. LÄS MER

  3. 12. Gene regulatory evolution in flycatchers: statistical approaches for the analysis of allele-specific expression

    Författare :Mi Wang; Hans Ellegren; Christopher Wheat; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ASE; gene expression evolution; bayesian; RPASE; flycatcher.; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Understanding the molecular mechanisms underlying evolutionary changes in gene expression is a major research topic in biology. While a powerful approach to study this is the analysis of allele-specific expression (ASE), most of previously published methods can only be applied to lab organisms. LÄS MER

  4. 13. Molecular approaches to the developmental biology of Norway spruce, Picea abies

    Författare :Karolina Tandre; Uppsala universitet; []

    Sammanfattning : Ontogeny depends on the developmental control of genes. In this thesis twoapproaches were taken to identify genes essential to developmental processes inthe conifer Norway spruce, Picea abies (L.) Karst. LÄS MER

  5. 14. Mass spectrometry based proteomics : data analysis and applications

    Författare :Yafeng Zhu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mass spectrometry (MS) based proteomics has become a widely used high throughput method to investigate protein expression and functional regulation. From being able to study only dozens of proteins, state-of-art MS proteomic techniques are now able to identify and quantify ten thousand proteins. LÄS MER

  7. 15. Analysis and Design of Rateless Codes

    Författare :Iqbal Hussain; Lars Kildehøj Rasmussen; Petar Popovski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The invention of turbo codes and the re-discovery of sparse graph codes constitute a milestone in error-correction codes designed for communication and storage systems. Sparse graph codes such as low-density parity-check codes can offer a performance that approaches the previously elusive Shannon capacity with reasonable practical computational complexity. LÄS MER
