Following increased efforts during the last decade to formulate mathematical models for the paper drying process, this paper presents a Modelica library, DryLib, which enables users to rapidly develop complex models of paper machine dryer sections. In addition, parameter optimization, model reduction and moisture control by means of Non-Linear Model Predictive Control is treated. These application

This chapter discusses several different aspects of the energy balance and physiological homeostasis of incubating birds, ranging from systematic, geographical and life history related variation in energy costs of incubation, to thermal considerations for birds on the nest, links between energy expenditure and fitness, and non-energetic costs of incubation. Our review of the literature shows that,

Objective This study provides the summary of current knowledge about migrant work in agriculture available from journal articles, books, reports and other relevant academic publications, focusing on political, economic, legal, social and medical aspects of migrant work in agriculture. Methods A systematic search was carried out on the LibHub and Google Scholar databases in order to compile the e

This paper deals with the construction and orbital stabilization of periodic solutions for a particular underactuated mechanical system with 2 degrees of freedom, the Furuta pendulum. It is shown that if a desired periodic motion is described by constraints imposed on the total energy of the system and on the value of the directly actuated variable, then this periodic motion can be constructed and

Possible fields of library research are indicated through a survey of relations and conflict areas between librarians and researchers in a university library, with examples taken from the history of Lund University Library.

ABSTRACT Doctoral thesis - Author: Lena Steffner Evaluation of urban environments, a method to measure experience The doctoral thesis builds on the licentiate thesis, Aesthetic evaluation of urban environments – a method using the public’s affective appraisals and experiences (2004). The central problem in the work is that experts and the public often differ in their evaluation of urban environme

Detta är en historiografisk studie av hur några välkända svenska historiker har använt sig av de isländska sagorna när de presenterat perioden som vi idag kallas vikingatid. Vikingatiden har haft en viktig funktion i konstruktioner av kollektiva identiteter, och i sökandet efter relevanta förfäder, vilket passar bra ur ett historiekulturellt perspektiv.När medicinprofessorn Olof Rudbeck skrev sitt“The Swedes of the Sagas. A Historiographical Study of the Old Norse Sagas and the Construction of the Viking Age.” This thesis is related to the construction of collective identities, and the search for a common ancestry. There are different types of characteristics which have been associated with the Viking Age, and this is a historiographical study of how a few, well-known, Swedish historians

Given the increasing interest in the association between exposure to air pollution and adverse health outcomes, the development of models that provide accurate spatio-temporal predictions of air pollution concentrations at small spatial scales is of great importance when assessing potential health effects of air pollution. The methodology presented here has been developed as part of the Multi-Ethn

Popular Abstract in Swedish Gamla människor har ökad känslighet för vätske- och blodförlust vilket indikerar ett generellt försämrat försvar vid tillstånd med nedsatt blodvolym i kärlsystemet (hypovolemi). Det medverkar sannolikt till en ökad kardiovaskulär morbiditet och mortalitet. De första tre artiklarna i föreliggande avhandling studerar de bakomliggande orsakerna, i förhoppning att en ökad fAged subjects have a decreased tolerance to hypovolemia, which could contribute to their increased cardiovascular morbidity. One possible etiological factor might be an age-related reduction in the efficiency of the baroreceptor reflex axis. In this study lower body negative pressure (LBNP) was used as a model for hypovolemic circulatory stress, and volumetric techniques applied for the study of p

This article forms a contribution to the ongoing scholarly debate on the possible effect of jus cogens norms. For the purpose of the article, it is assumed that peremptory norms certainly exist in positive international law. According to the argument, even if we limit the effects of jus cogens norms to those described in the 1969 Vienna Convention, the jus cogens concept takes us farther than most
