  2. 1. Preparatory Studies to Introduce Regulatory T Cells in Clinical Transplantation

    Author : David Berglund; Gunnar Tufveson; Olle Korsgren; David Sachs; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transplantation; Tolerance; Cell therapy; Regulatory T cell; In vivo imaging; Cell purification;

    Abstract : Solid organ transplantation has evolved from being an experimental procedure to a life-saving treatment for patients with end-stage organ failure. The risk of losing a transplant due to acute rejection is very low with the use of modern immunosuppressive protocols and the short-term results are impressive. READ MORE

  4. 2. Improving Software Security by Preventing Known Vulnerabilities

    Author : David Byers; Nahid Shahmehri; David Basin; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Software security; software process improvement;

    Abstract : From originally being of little concern, security has become a crucial quality factor in modern software. The risk associated with software insecurity has increased dramatically with increased reliance on software and a growing number of threat agents. Nevertheless, developers still struggle with security. READ MORE

  6. 4. Resource Allocation in Multi-Antenna Communication Systems with Limited Feedback

    Author : David Hammarwall; Björn Ottersten; David Gesbert; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Abstract : The use of multiple transmit antennas is considered a key ingredient to significantly improve the spectral efficiency of wireless communication systems beyond that of currently employed systems. Transmit beamforming schemes have been proposed to exploit the spatial characteristics of multi-antenna radio channels; that is, multiple-input single-output (MISO) channels. READ MORE

  7. 5. Electromagnetic transformer modelling including the ferromagnetic core

    Author : David Ribbenfjärd; Göran Engdahl; David Jiles; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power transformer; hysteresis; dynamic hysteresis; dynamic magnetization; eddy currents; excess losses; leakage flux; winding model; core model; magnetic measurements; magnetic materials; Electric power engineering; Elkraftteknik;

    Abstract : In order to design a power transformer it is important to understand its internal electromagnetic behaviour. That can be obtained by measurements on physical transformers, analytical expressions and computer simulations. READ MORE
