  2. 26. Massive MIMO: Prototyping, Proof-of-Concept and Implementation

    Author : Steffen Malkowsky; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Massive MIMO; Testbed Design; Prototyping; ASIP; Processor;

    Abstract : Wireless communication is evolving rapidly with ever more connected devicesand significantly increasing data rates. Since the invention of the smartphoneand the mass introduction of mobile apps, users demand more andmore traffic to stream music, watch high-definition video or to simply browsethe internet.

  4. 27. “Taking the next step” : whole-body biomechanical gait analysis, and user-perspectives on robotic-assisted gait training post-stroke

    Author : Heidi Nedergård; Charlotte Häger; Marlene Sandlund; Susanne Palmcrantz; Erika Franzén; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stroke; robotic-assisted; electro-mechanical; gait training; gait analysis; user-perspectives; kinematics; physiotherapy; fysioterapi;

    Abstract : Background: Stroke, and its subsequent motor function impairments may result in limited gait ability characterised by compensatory movement patterns that include deviations and asymmetries. How these movement patterns should be evaluated and quantified in order to be monitored and treated in the long term is not yet standardised. READ MORE

  5. 28. Multiresolution Continuum Theory and Dislocation Density Based Constitutive Relations

    Author : Hao Qin; Kenneth Runesson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik; Centrumbildning - Centrum för högpresterande stål CHS ; Centre - Centre for High Performance Steel CHS ;

    Abstract : In classical description, the mechanical state of a material point depends on the variables defined at this point solely. It can integrate and catch some aspects of the material’s microstructure by conventional homogenization method. READ MORE

  6. 29. Impacts and drivers of insect herbivory on element cycling in forests globally

    Author : Bernice Hwang; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biogeochemical cycling; folivory; insect cadavers; insect frass; insect herbivory; litter decomposition; nutrient cycling; carbon; nitrogen; phosphorus; silicon; silica;

    Abstract : The effects of insect herbivores on forest functioning are not well understood even though they can have important impacts on ecosystem processes by intercepting foliage before resorption and depositing nutrient-rich materials to the soil. In this thesis, I investigated the impact and drivers of insect folivores on carbon (C), nitrogen (N), phosphorus (P) and silica (Si) cycling in broadleaf forests, and how this varies with major climate variables.

  7. 30. Soil nitrogen fluxes and root uptake in the boreal forest : key processes to plant nitrogen nutrition

    Author : Olusegun Ayodeji Oyewole; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Nitrogen (N) is essential for growth and net primary production of plants. However, N acquisition by plants is influenced by movement of soil N compounds from bulk soil to plant roots and uptake of N by roots. This thesis is aimed at deepening our knowledge on these key processes involved in plant N acquisition in the N-limited boreal forest. READ MORE
