1. 21. Dynamics of Coinfection : Complexity and Implications

   Författare :Samia Ghersheen; Vladimir Kozlov; Uno Wennergren; Vladimir Tkachev; Åke Brännström; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Living beings are always on risk from multiple infectious agents in individual or in groups. Though multiple pathogens' interactions have widely been studied in epidemiology. Despite being well known, the co-existence of these pathogens and their coinfection remained a mystery to be uncovered. LÄS MER

3. 22. Reappraisal of market efficiency tests arising from nonlinear dependence, fractals, and dynamical systems theory

   Författare :Gun-Ho Cha; Handelshögskolan i Stockholm; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : The efficient market hypothesis (EMH) has long been perceived as the cornerstone of modern finance theory. However, the EMH has also recently been dismissed as "the most remarkable error in the history of economic theory" (Wall Street Journal, Oct. 23. 1987). LÄS MER

4. 23. Analysis of Radio Channel Measurements Using Multiple Base Stations

   Författare :Niklas Jaldén; Björn Ottersten; Bo Göransson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Channel Modellin; Telecommunication; Telekommunikation;

   Sammanfattning : Future wireless communication systems will utilize the spatial properties of the wireless channel to improve the spectral efficiency and thus increase capacity. This is realized by deploying multiple antennas at both the transmitter and receiver. LÄS MER

5. 24. Species’ responses to an ever-changing world

   Författare :Jonatan Årevall; Anna Eklöf; Uno Wennergren; Frederick De Laender; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : One of nature’s most astonishing features is the diversity of life, as more than a million species has been identified and classified. This diversity not only have a intrinsic value, but sustains us humans through a multitude of ecosystem services. Many of these services are critical for our sustenance. LÄS MER

7. 25. Essays on Capability Indices for Autocorrelated Data

   Författare :Erik Wallgren; Anders Christoffersson; Jan Wretman; Uppsala universitet; []
   Nyckelord :Statistics; Capability Indices; Autocorrelated data; Monte Carlo Simulations; Statistik;

   Sammanfattning : The use of process capability indices in the industry is traditionally based on the assumptions that a sample from a process are observations on independently, identically and normally distributed random variables, IIN. However, all three assumptions are open to discussion and in this thesis, the estimation of the indices is studied when the assumption of independence is not fulfilled. LÄS MER
