  2. 1. Vibrations induced by surface roughness in nonlinear rolling contacts

    Author : Oskar Erik Lundberg; Ines Lopez Arteaga; Svante Finnveden; Will Graham; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rolling contact; nonlinear contact; contact stiffness; contact filter; state-dependent method; relative displacement; wheel-rail contact; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : For efficient transportation in either trains, busses or passenger cars, rolling elements such as wheels, tyres, bearings and transmission elements are fundamental. The energy efficiency and the generation of noise and vibrations in rolling contacts depend on the surface roughness of contacting bodies. READ MORE

  4. 2. Operationalizing Industrial Ecology in the Waste Sector : Roles and tactics for circular value innovation

    Author : Graham Aid; Nils Brandt; Monika Olsson; Maria Malmström; Leenard Baas; Stefan Anderberg; Mats Eklund; Anna Björklund; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : The take-make-waste approach to resource management in human production and consumption systems is contributing to a variety of environmental and social problems worldwide. Additionally, as the world’s population and affluence increase, so do the negative impacts of poor resource management. READ MORE

  5. 3. Modeling drying of iron ore pellets

    Author : Anna-Lena Ljung; Graham Nathan; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Iron ore pellets are a highly refined product supplied to the steel making industry for use in blast furnaces or direct reduction processes. The use of pellets offers many advantages such as customer adopted products, transportability and mechanical strength yet the production is time and energy consuming. READ MORE

  6. 4. Methodological Studies on Models and Methods for Mixed-Effects Categorical Data Analysis

    Author : Maria C. Kjellsson; Mats O. Karlsson; Siv Jönsson; Gordon Graham; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacodynamics; Categorical data; Markov model; Modelling; NONMEM; NLMIXED; Laplace; Gaussian quadrature; Back-Step Method; Proportional odds model; Differential odds model;

    Abstract : Effects of drugs are in clinical trials often measured on categorical scales. These measurements are increasingly being analyzed using mixed-effects logistic regression. However, the experience with such analyzes is limited and only a few models are used. READ MORE

  7. 5. Cellular and Viral Factors that Control Human Papillomavirus Type 16 Late Gene Expression

    Author : Monika Somberg; Stefan Schwartz; Sheila Graham; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Virology; Virologi; Medical Virology; Medicinsk virologi;

    Abstract : Human papillomavirus type 16 (HPV-16) is the major cause of cervical cancer. We speculate that inhibition of HPV-16 late gene expression is a prerequisite for establishment of persistence and progression to cervical cancer. READ MORE
