  1. 1. Stress, sleep disturbance, and related ill-health : from prevalence and risk-factors to indicated interventions

    Author : Per Höglund; Steven Nordin; Camilla Hakelind; Steven Linton; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Stress-related ill-health; Prevalence; Risk factors; Burnout; Insomnia; Non-experts; Low intensity psychological interventions; Primary care; Scalability; Indicated prevention.; klinisk psykologi; Clinical Psychology; epidemiologi; Epidemiology;

    Abstract : With focus on stress-related ill-health and insomnia/sleep disturbance, the overall aim of this thesis was to determine severity and prevalence, risk factors and effectiveness of low-intensity group sessions. This was accomplished by taking epidemiological and quasi-experimental approaches. READ MORE

  2. 2. Bandwidth Limited Distributed Optimization with Applications to Networked Cyberphysical Systems

    Author : Sindri Magnússon; Carlo Fischione; Steven Low; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Optimization; Resource Allocation; Power Networks; Limited Communication; Networks; Cyberphysical Systems; Wireless Sensor Networks; Internet of Things; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The emerging technology of Cyberphysical systems consists of networked computing, sensing, and actuator devices used to monitor, connect, and control physical phenomena. In order to economically and sustainably operate Cyberphysical systems, their devices need to cooperate over a communication network to solve optimization problems. READ MORE

  3. 3. Low social support and disturbed sleep : epidemiological and psychological perspectives

    Author : Maria Nordin; Anders Knutsson; Elisabet Sundbom; Steven Linton; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; social support; sleep initiation and maintenance disorder; psychological adaptation; myocardial infarction; social psychology; public health; mental health; occupational health; epidemiology; cohort studies; Public health science; Folkhälsovetenskap;

    Abstract : The Swedish work force underwent dramatic changes during an economic crisis in the 1990s. In the aftermath, sick leave increased at an unprecedented rate and stress-related disorders, such as burnout, depression, and sleep disturbances replaced earlier work-related diagnoses. READ MORE

  4. 4. Developing a food waste-based volatile fatty acids platform using an immersed membrane bioreactor

    Author : Steven Wainaina; Jukka Rintala; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; food waste; anaerobic digestion; volatile fatty acids; immersed membrane bioreactor; edible filamentous fungi; Resource Recovery; Resursåtervinning;

    Abstract : Approximately 1.3 billion tons of food waste is produced globally every year. In principle, all the resources in the supply chain are lost (e.g. READ MORE

  5. 5. Finite element modelling of the mechanics of solid foam materials

    Author : Steven Ribeiro-Ayeh; Dan Zenkert; Andrew M. Kraynic; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering design; point-stress criterion; bi-material interface; foam; cellular sollid; micro-mechanical modelling; Konstruktionsteknik; Construction engineering; Konstruktionsteknik;

    Abstract : Failure of bi-material interfaces is studied with the aim to quantify the influence of the induced stress concentrations on the strength of the interfaces. A simple point-stress criterion, used in conjunction with finite element calculations, is evaluated to provide strength predictions for bi-material bonded joints and inserts in polymer foam. READ MORE
