Control design is often done based on simplified models. After design it is necessary to verify that the real closed loop system behaves well. This is mostly done by experiments and simulations. Theoretical analysis is an important complement to this that can help to verify critical cases. Structural information about uncertainties, time-variations, nonlinearities, and signals can be described by
Popular Abstract in Swedish I de flesta reglerproblem är syftet att hålla utsignalen nära ett önskat värde trots störningar som påverkar systemet. Ibland är det bästa referensvärdet inte känt i förväg. I stället skall det hittas i realtid för att optimera systemets prestanda. Denna avhandling behandlar en så kallade probing-strategi som kan tillämpas för denna klass av problem. Fokus ligger i tillIn most control problems the objective is to control the output at a desired value in spite of disturbances. In some cases, the best setpoint is not known a priori and it should be found online to optimize the process performance. This thesis examines a probing strategy that can be applied for this class of problems. The focus is on the application of the technique to the control of feed supply in
The rapid progress in scanning probe microscopy (SPM) techniques in the last decade has induced an increasing need for manufacturing advanced SPM tips. One important case is conductive and transparent tips. For such tips, only a few techniques have been proposed. which are either expensive or have poor reproducibility. We here propose a simple and cheap sol-gel technique to prepare fibers with a s
The comfortable garment is about creating a comfortable experience with all that it implies, both physiologically and psychologically. The project describes the interaction between expectations and needs, in and across situations, in order to be and feel prepared, relaxed, and while still well dressed. The Expectation of this project is that it should be an eye opener to take get new knowledge abo
This report evaluates and compares the methods in fire inspection at Malmø Fire Brigade and Copenhagen Fire Brigade. The report also examines fire safety laws and regulations and the educational differences of the fire inspectors in Malmø and Copenhagen. The investigation is a project for Malmø Fire Brigade and Copenhagen Fire Brigade in co-operation with the Department of Fire Safety Engineering
Denna uppsats syftar till att undersöka hur de två faktorerna självförtroende och inre motivation skiljer sig åt mellan personer som har kommit olika långt i riktning mot ett fysiskt aktivt liv. 144 försökspersoner besvarade 19 frågor i en enkätstudie. Deras svar angående motionsvanor och attityd gentemot fysisk aktivitet placerade dem i olika faser i den transteoretiska modellen. Därefter jämförd
Studien undersökte grundskolelärares inställning till att bli utvärderade av sina elever. Metoden var kvantitativ och en enkät utformades av författarna för att förstå lärarnas inställning. Svar från 55 grundskolelärare analyserades och presenterades i studien. Resultatet visade att grundskolelärare inte anser att elevutvärderingar kan bidra till att förbättra undervisningen. Lärarna trodde att deThe study investigated grade school teachers’ attitudes about pupil evaluation of teaching. The method used was quantitative and a questionnaire was developed to capture the teachers’ attitudes. A sample of 55 grade school teachers was analyzed and presented in this study. The results indicated that grade school teachers do not find pupil evaluations helpful in improving their teaching. The teache
During 2010-2013, we investigated the effects of stump harvesting on greenhouse gas (GHG) fluxes of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) with the flux-gradient technique at four experimental plots in a hemiboreal forest in Sweden. All plots were clear-cut and soil scarified and two of the plots were additionally stump harvested. The two clear-cut plots served as control plot
Remote sensing-based models are an adequate tool to estimate carbon dioxide (CO2) uptake by terrestrial ecosystems, and to upscale the results from ecosystem to regional or global scales. In this study we compare three models driven by Sentinel-2 derived vegetation indices together with eddy covariance (EC) measured CO2 flux and radiation data in order to estimate gross primary production (GPP) in
Vitamin C may impact the efficiency of radiation therapy (RT) in breast cancer. The effects of RT alone or in combination with vitamin C in SKBR3, MDA-MB-231, and MCF7 cells were compared using clonogenic assay, proliferation assay (MTT), cell cycle analysis, and Western blot. Vitamin C use was assessed in 1803 breast cancer patients 2002–2017 in relation to clinicopathological features and recurr
Polygenic risk scores (PRS) for prostate cancer incidence have been proposed to optimize prostate cancer screening. Prediction of lethal prostate cancer is key to any stratified screening program to avoid excessive overdiagnosis. Herein, PRS for incident prostate cancer was evaluated in two population-based cohorts of unscreened middle-aged men linked to cancer and death registries: the Västerbott
The global temperature rise is proportional to the cumulative amount of CO2 emissions to the atmosphere. This observation is consistent between climate models and historical observations. It has also given rise to the concept of a carbon budget, which sets a threshold for the amount of CO2 that can be emitted into the atmosphere while still fulfilling political goals such as the Paris Agreement.Te
There is a growing interest in industry and academia in machine learning (ML) testing. We believe that industry and academia need to learn together to produce rigorous and relevant knowledge. In this study, we initiate a collaboration between stakeholders from one case company, one research institute, and one university. To establish a common view of the problem domain, we applied an interactive r
After World War I, millions of men went back from the war front promised of land, work and social justice, but their expectations were unfulfilled by the governments of European countries. In this context, the political landscape was enriched of new ideas, and several new parties, movements and associations born across Europe. In Italy, ANMIG (Disabled Ex-Servicemen National Association) was
Follow-up survey on legal status of information society service providers in the post-CDSM Directive era in Sweden, focusing on service providers as intermediaries and as users of copyright-protected content (March 2022). Phase 2 report, part of ReCreating Europe project WP6 - Intermediaries.
Cellular stress contributes to the capacity of melanoma cells to undergo phenotype switching into highly migratory and drug tolerant dedifferentiated states. Such dedifferentiated melanoma cell states are marked by loss of melanocyte specific gene expression and increase of mesenchymal markers. Two crucial transcription factors, MITF and SOX10, important in melanoma development and progression hav
There is a need of problematizing taken for granted assumptions in the conceptualization of collaborative housing when attempting to link collaborative housing and social integration. What are the difficulties and opportunities that migrants and non-migrants face in accessing collaborative housing projects? Addressing such type of questions will help to capture exclusionary processes affecting old
This study investigates possible structural changes of an intrinsically disordered protein (IDP) when it adsorbs to a solid surface. Experiments on IDPs primarily result in ensemble averages due to their high dynamics. Therefore, molecular dynamics (MD) simulations are crucial for obtaining more detailed information on the atomistic and molecular levels. An evaluation of seven different force
Mouse hematopoietic stem cells (HSCs) have been extensively defined both molecularly and functionally at steady state, while regenerative stress induces immunophenotypical changes that limit high purity isolation and analysis. It is therefore important to identify markers that specifically label activated HSCs to gain further knowledge about their molecular and functional properties. Here, we asse
