1. 1. Exploring Alternative Massive MIMO Designs : Superimposed Pilots and Mixed-ADCs

   Författare :Daniel Verenzuela; Emil Björnson; Luca Sanguinetti; Michalis Matthaiou; Mohamad Assaad; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The development of information and communication technologies (ICT) provides the means for reaching global connectivity that can help humanity progress and prosper. This comes with high demands on data traffic and number of connected devices which are rapidly growing and need to be met by technological development. LÄS MER

   Sammanfattning : The enormous challenge of climate change is discussed and debated today because of its major impact on life on Earth. The forests have an important role to play as the plants absorb carbon dioxide (CO2) from the atmosphere through their photosynthesis and the growing tree retain carbon (C). LÄS MER

7. 5. Birch Stem and Wood Traits in Genetic and Silviculture Trials in Southern Sweden

   Författare :Grace Jones; Stergios Adamopoulos; Mateusz Liziniewicz; Mikael Andersson; Sheikh Ali Ahmed; Erkki Verkasalo; Linnéuniversitetet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; acoustic velocity; Betula spp.; dynamic MOE; genetic parameters; grain angle; hardwood; Itrax densitometry; mixed forests; non-destructive testing; stem form; akustisk velocitet; Betula spp.; blandskog; densitometri; genetiska parametrar; icke destruktiva metoder; Itrax; lövträ; skogsodling; stamkvalitet; vedsegenskaper; Forestry and Wood Technology; Skog och träteknik;

   Sammanfattning : Swedish tree species of birch (silver: Betula pendula and downy: B. pubescens) are often neglected during forest management activities, resulting in low value logs. This thesis investigated birch stem characteristics and wood properties important for solid wood products, in genetics and management trials in southern Sweden. LÄS MER
