  1. 11. Generalized APP Detection for Communication over Unknown Time-Dispersive Waveform Channels

    Författare :Anders Hansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The principle of transmitting time-equidistant pulses to carry discrete information is fundamental. When the pulses overlap, intersymbol interference occurs. Maximum-likelihood sequence detection of such signals observed in additive white Gaussian noise (AWGN) was known in the early 1970s. LÄS MER

  3. 12. Nya utmaningar, gamla strategier - om distriktsläkares yrkesroll och attityder till samarbete

    Författare :Anders Hansson; Göteborgs universitet; []
    Nyckelord :balancing; general practitioners; professional role; team-work; interdisciplinary; medical students; district nurses;

    Sammanfattning : Background: Being confronted by patients with incurable chronic and psychosocially complicated conditions constitutes one of the major challenges for today’s General Practitioners (GP). The traditional biomedical disease model is often insufficient. Furthermore, today’s patients are educated, self-assured and make demands. LÄS MER

  4. 13. Spectral estimates for the magnetic Schrödinger operator and the Heisenberg Laplacian

    Författare :Anders Hansson; Ari Laptev; B Malcolm Brown; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spectral theory; Schrödinger operator; magnetic field; Aharonov-Bohm; Lieb-Thirring; diamagnetic inequality; Heisenberg group; Heisenberg Laplacian; hypoelliptic; spektralteori; Schrödingeroperator; magnetfält; Aharonov-Bohm; Lieb-Thirring; diamagnetisk olikhet; Heisenberggrupp; Heisenberg-Laplace-operator; hypoelliptisk; MATHEMATICS; MATEMATIK;

    Sammanfattning : I denna avhandling, som omfattar fyra forskningsartiklar, betraktas två operatorer inom den matematiska fysiken. De båda tidigare artiklarna innehåller resultat för Schrödingeroperatorn med Aharonov-Bohm-magnetfält. LÄS MER

  5. 14. On preoperative treatment selection and magnetic resonance imaging in rectal cancer

    Författare :Anders Hansson Elliot; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In Sweden, 2000 patients are diagnosed with rectal cancer annually. Developments in surgery have improved survival and the addition of preoperative radiotherapy (RT) or chemoradiotherapy (CRT) has reduced local recurrence rates to 5 %. However, (C)RT is associated with side effects. LÄS MER

  7. 15. Warhead penetration in concrete protective structures

    Författare :Håkan Hansson; Anders Ansell; Mattias Unosson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Warhead penetration; FE analysis; experiment; material modelling; fortifications; Stridsdelspenetration; FE-analyser; experiment; materialmodellering; fortifikationer;

    Sammanfattning : The analysis of penetration of warheads in concrete protective structures is an important part of the study of weapon effects on protective structures. This type of analysis requires that the design load in the form of a warhead is determined, and its characteristic and performance within a protective structure is known. LÄS MER
