1. 1. Interference Alignment with Imperfect Channel Knowledge and Secrecy Constraints

   Författare :Zhao Wang; Mikael Skoglund; Ming Xiao; Sheng Yang; KTH; []
   Nyckelord :Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : In this thesis, the degrees of freedom (DOF) of wireless networks are studied with imperfect channel state information at transmitters (CSIT) and/or secrecy constraints. Different interference alignment schemes are proposed to establish the DOF lower bound for a variety of wireless networks. LÄS MER

3. 2. A weighted correlation approach of the density functional theory for an inhomogeneous fluid at an interface

   Författare :Zhao Wang; Longcheng Liu; Ivars Neretnieks; Małgorzata Borówko; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inhomogeneous fluid; interface; density functional theory;

   Sammanfattning : This doctoral thesis presents a newly developed density functional theory (DFT), i.e., the weighted correlation approach (WCA), to study the structural and thermodynamic properties of an inhomogeneous fluid at an interface. LÄS MER

4. 3. Recalcitrance of wood to biochemical conversion : feedstock properties, pretreatment, saccharification, and fermentability

   Författare :Zhao Wang; Leif Jönsson; Brett Pletschke; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recalcitrance; Pretreatment; Enzymatic saccharification; Ionic liquid; Steam explosion; Enzyme inhibition; Non-productive binding; Microbial inhibitors;

   Sammanfattning : Lignocellulose is an inexpensive and abundant renewable resource that can be used to produce advanced biofuels, green chemicals, and other bio-based products. Pretreatment and efficient enzymatic saccharification are essential features of bioconversion of lignocellulosic biomass. LÄS MER

5. 4. A health coaching self-management programme for patients with Chronic Obstructive Pulmonary Disease : An explorative and interventional study

   Författare :Lan Wang; Jan Mårtensson; Yue Zhao; Annette Nygårdh; Inger Ekman; Jönköping University; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic Obstructive Pulmonary Disease; Self-management; Health coaching;

   Sammanfattning : Background: Chronic Obstructive Pulmonary Disease (COPD) is a primary cause of chronic morbidity and mortality and contributes to an increased economic and social burden on patients and families. Self-management education as one non-pharmacological treatment approach is highlighted in guidelines. LÄS MER

7. 5. Microbial communities : descriptors of environmental change in marine ecosystems

   Författare :Li Zhao; Agneta Andersson; Xiao-Ru Wang; Alexander Eiler; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In northern marginal seas, like the northern Baltic Sea, climate change will lead to many alterations, for example increased inflows of nutrients and dissolved organic matter (DOM). Nutrients and DOM are fundamental drivers shaping marine microbial communities, including both bacterial and phytoplankton populations. LÄS MER
