  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

    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

  4. 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; Högskolan i Jönköping; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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
