  3. 2. Resin composites : Sandwich restorations and curing techniques

    Författare :Anders Lindberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Adaption; Clinical; Degree of conversion; Depth of cure; Flowable; Resin composite; Restorations; SEM; Medicin;

    Sammanfattning : Since the mid-1990s resin composite has been used for Class II restorations in stress-bearing areas as an alternative to amalgam. Reasons for this were the patients’ fear of mercury in dental amalgam and a growing demand for aesthetic restorations. LÄS MER

  4. 3. Wireless Sensor Network Positioning Techniques

    Författare :Mohammad Reza Gholami; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; outer-approximations; Cram; Wireless sensor network; nonlinear and linear least squares; cooperative positioning; projection onto convex sets; maximum likelihood esti- mator;

    Sammanfattning : Position information is one of the key requirements for wireless sensor networks(WSNs). Since GPS receivers have drawbacks when used in low-power sensor nodes,mainly due to latency in position recovery and limited access to GPS satellites in indoor-type scenarios, extracting the position information by means of the network itself, so-called positioning or localization, has been considered an eective solution for the posi-tioning problem.

  5. 4. Utilizing Channel State Information in Space-Time Coding : Performance Limits and Transmission Techniques

    Författare :George Jöngren; KTH; []
    Nyckelord :Beamforming; Channel feedback; MIMO; Space-time coding; Wireless Communication;

    Sammanfattning : This thesis deals with performance limits and transmissiontechniques for a wireless communication link where at least thetransmitter is equipped with an antenna array and moreover hasaccess to possibly imperfect channel state information.An antenna array on the transmit side provides the systemwith an extra spatial dimension that can be utilized for codingboth in the spatial as well as the temporal domain.

  7. 5. New apheresis techniques in transplantation

    Författare :Gunilla Kumlien; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The shortage of organs for transplantation is a global problem and therefore it is of outmost importance to increase the number of donations and improve long term graft survival. As an effort to increase kidney donations, living kidney donors are being increasingly used and both patient and graft survival is superior after living donation compared with kidney transplantations using organs from deceased donors.
