  1. 16. Structure analysis and molecular recognition studies of bio-functionalized surfaces

    Författare :Cecilia Vahlberg; Kajsa Uvdal; Carla Puglia; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Biological and chemical reactions involved in physiological processes are often complex and very sophisticated. Such processes can be mimicked in the laboratory to obtain important knowledge, valuable for the  development of new diagnostic methods, drugs and biosensors. LÄS MER

  3. 17. Safety Format for Non-linear Analysis of RC Structures Subjected to Multiple Failure Modes

    Författare :Filippo Sangiorgio; Johan Silfwerbrand; Giuseppe Mancini; Diego Allaix; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis treats the safety format for non-linear analysis of reinforced concrete (RC) structures subjected to multiple failure modes. The purpose is to identify questions which are poorly understood and ambiguous about the behaviour of structures that may fail due to a number of possible failure modes (e.g. LÄS MER

  4. 18. Reliability-based evaluation of concrete dams

    Författare :Marie Westberg; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spatial correlation; assessment; concrete dam; uplift; structural reliability analysis; existing structure;

    Sammanfattning : Swedish concrete dams are designed and assessed based on deterministic design using safety factors. The combination of increasing age, new methods for calculation of design floods and increasing demands by society to ensure a high level of safety, has resulted in upgrading and rebuilding needs for dams.

  5. 19. Charge Sampling Circuits and A/D Converters - Theory and Experiments

    Författare :Gang Xu; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pipelined A D converter; sigma-delta modulator; differential difference comparator; 2-step A D converter; FIR filter; analog filter; thermal noise; clock jitter; sub-sampling; RF sampling; current-mode sampling; Charge samling; A D converter; flexible A D converter; Electronics and Electrical technology; Elektronik och elektroteknik;

    Sammanfattning : The analysis of general charge sampling technique is presented in this thesis. Charge sampling integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. The analysis focuses on the performance of general charge sampling circuits for signal capture. LÄS MER

  7. 20. Modeling, Control and Protection of Low-Voltage DC Microgrids

    Författare :Daniel Salomonsson; Lennart Söder; Brian K. Johnsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circuit transient analysis; dc power systems; dispersed storage and generation; load modeling; power conversion; power distribution control; power distribution faults; power distribution protection; power electronics; Electric power engineering; Elkraftteknik;

    Sammanfattning : Current trends in electric power consumption indicate an increasing use of dc in end-user equipment, such as computers and other electronic appliances used in households and offices. With a dc power system, ac/dc conversion within these loads can be avoided, and losses reduced. LÄS MER
