  1. 26. Decentralized Network Optimization in Wireless Networks

    Författare :Yuzhe Xu; Carlo Fischione; Tommaso Melodia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Distributed estimation and distributed resource allocation are two important services in future cyber-physical wireless networks. The former aims to estimate, or track, physical variables of a phenomenon monitored by a wireless network, whereas the latter aims to optimally assign the limited communication resources to the nodes in a wireless network.

  2. 27. A Remote Monitoring and Control System for Cultural Heritage Buildings Utilizing Wireless Sensor Networks

    Författare :Jingcheng Zhang; Qin-Zhong Ye; Shaofang Gong; Markus Krüger; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This dissertation presents the study of a wireless remote monitoring and control system utilized for cultural heritage preservation purpose. The system uses wireless sensor networks to remotely monitor and control the indoor climate, i.e., temperature and relative humidity of the cultural buildings. LÄS MER

  3. 28. Protection Strategies to Mitigate Major Power Systems Breakdowns

    Författare :Mattias Jonsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system protection schemes; transient instability; distance protection; power swing detectors; voltage instability; generator coherency; wide area protection; out-of-step protection;

    Sammanfattning : This thesis deals with new methods to improve the performance of power system protection in the case of voltage- and transient instability. These methods are designed primarily to mitigate power system breakdown. Relay algorithms are proposed where conventional distance protection is combined with additional relay criteria. LÄS MER

  4. 29. Regulation of TGF-β Signaling by Post-Translational Modifications

    Författare :Peter Lönn; Aristidis Moustakas; Carl-Henrik Heldin; Petra Knaus; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TGF-β; Smad; PARP-1; PARG; ALK5; SIK; signal transduction; transcription; post-translational modification; phosphorylation; ubiquitin; ADP-ribosylation; DNA-binding; receptor degradation; Cell and molecular biology; Cell- och molekylärbiologi; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Sammanfattning : Transforming growth factor-β (TGF-β) signaling is initiated when the ligand binds to type II and type I serine/threonine kinase receptors at the cell surface. Activated TGF-β type I receptors phosphorylate R-Smads which relocate, together with co-Smads, to the cell nucleus and regulate transcription. LÄS MER

  5. 30. Design, Synthesis and Properties of Bipyridine-capped Oligothiophenes for Directed Energy and Electron Transfer in Molecular Electronic Applications

    Författare :Lasse Nurkkala; Simon Dunne; Sarah Angus-Dunne; Edwin Constable; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular Electronics; Organic Synthesis; Ruthenium; Pyridyl Complexes; Ligand Design; Chemical engineering; Kemiteknik; Biotechnology Chemical Engineering; bioteknik kemiteknik;

    Sammanfattning : The earliest landmark in computer technology was construction of the Electronic Numerial Integrator and Computer, ENIAC. Computational switching was performed with vacuum tubes and relays, rather large in size, making this computer rather unwieldy. LÄS MER
