We present the open-source software framework in JModelica.org for numerically solving large-scale dynamic optimization problems. The framework solves problems whose dynamic systems are described in Modelica, an open modeling language supported by several different tools. The framework implements a numerical method based on direct local collocation, of which the details are presented. The implemen
We consider the problem of gray-box identification of dynamic models for mechanical systems. In particular, the problem is approached by means of continuous-time system identification using subspace-based methods based on discrete-time input-output identification data. A method is developed, with the property that the structure of the model resulting from fundamental physical first principles is o
A method for determination of polycyclic aromatic hydrocarbons (PAHs) from aerosols was developed. Instead of conventionally used non-polar or slightly polar phenylmethylpolysiloxane column a highly polar, highly substituted, cyanopropyl column (VF-23 MS) was used for separation of PAHs. Based on hollow fiber micro-porous membrane liquid-liquid extraction (HF-MMLLE) a method was developed for samp
Abstract in UndeterminedMinimum distances and maximum likelihood error probabilities of serial turbo codes with uniform interleaver are analyzed. It is shown that, for a fraction of interleavers approaching one as the block-length grows large, the minimum distance of serial turbo codes grows as a positive power of their block-length, while their error probability decreases exponentially fast in so
A major challenge for a person with diabetes is to adapt insulin dosage regimens and food intake to keep blood glucose within tolerable limits during daily life activities. The early knowledge about the effects of inputs on glycemia would provide the patients with invaluable information for appropriate on-the-spot decision making concerning the management of the disease. Against this background, i
Industrial robots are usually programmed to follow desired trajectories, and are very good at position-controlled tasks. New applications, however, often require physical contact between the robot and its environment, and then the position control accuracy is generally not sufficient. Force control is a suitable alternative. The environment is often stiff, and then it is crucial to design appropri

Online retail is playing an ever increasing role in business today and one of the critical tasks in online retail management is the understanding of how to create an offering that would yield maximum value for the consumers and differentiate the retailer from competition. If an online retailer understands how the online retail offering is perceived and evaluated by customers, it becomes possible t
Title: Leadership Driving Successful Implementation of Continuous Improvement Programs - A Case Study Using the Path Goal Model Authors: Johanna Gustafsson, Paulina Hornay Supervisors: Stein Kleppestø, Ph.D., Associate professor, Department of Business Administration, School of Economics and Management, Lund University.

Some practices are seen as so serious and damaging to competition that they are presumed to have restrictive effects on competition. Having a category of restrictions that are forbidden benefits both companies, as it creates legal certainty, and the Commission which would not not have to go through a burdensome investigation. In recent decades, the interpretation of restriction by object has cause
This paper studies the high-frequency behavior of the USD/SEK currency pair on the arrival of macroeconomic news emanating from Sweden and the United States. By using exchange rate data sampled at one minute-by-minute quotations and market expectations from the Bloomberg Terminal, the study finds systematic effects of news on exchange rate returns. The majority of news is immediately incorporated
Introduction: Flexible Assertive Community Treatment (FACT) is implemented in Swedish general Mental Health Services. While FACT focuses on supporting the participation and personal recovery of individuals with complex mental health needs, critical components enabling these aspects are poorly understood. The aim of this study was to understand the critical components of FACT delivery supporting pa
Perceiving and understanding human motion is a fundamental problem in computer vision, with diverse applications encompassing sports analytics, healthcare monitoring, entertainment, and intelligent interactive systems. Multi-camera systems, by capturing multiple viewpoints simultaneously, enable robust tracking and reconstruction of human poses in 3D, overcoming limitations of single-view approach
Dating the bottommost section of an ice core is often complicated by strong layer thinning and possible disturbances in the stratigraphy. The radioactive decay of atmospherically produced 36Cl and 10Be can provide age estimates, where traditional methods can no longer be used. In this study, we investigated ice from the bottom of the Skytrain ice core, which was drilled in West Antarctica next to
Ice cores are unique archives of paleo-climate information and require accurate dating for its interpretation. Continuous chronologies are usually based on time markers, stratigraphic matching, and orbital tuning, but often end several meters above bedrock, because extreme thinning and sometimes disturbances in the stratigraphy complicate the identification of climate signals and their alignment w
The purpose of this thesis is to build on the debate on the importance of gender awareness in peacebuilding and explore the role of men and masculinities in challenging norms of violence and building a culture of peace in Colombia. Semi-structured interviews were conducted in Bogotá with seven organisations working with masculinities and eleven organisations working with women’s rights. The data g
Det är välkänt att det industriella jordbruket har omfattande negativa sociala, ekonomiska och miljömässiga effekter. Hållbart jordbruk ses som ett alternativ till detta nedbrytande system. Dess syfte är istället att skapa ett jordbruk som är hållbart på lång sikt. Med detta som utgångspunkt undersöker denna uppsats hur den gemensamma jordbrukspolitiken (CAP) har påverkat hållbart jordbruk i SveriIt is well known that industrial agriculture has extensive negative social, economic and environmental effects. Sustainable agriculture has been designed as a way of out this negative cycle, and is meant to create an agricultural system with temporal stability. With this starting point, this thesis investigates how the Common Agricultural Policy (CAP) has affected sustainable agriculture in Sweden
After authoritarian periods of human rights abuses by the state, trust in state institutions is likely to have eroded among most citizens. One way to try to re-establish this trust - which many researchers believe is essential to make democracy work - is to hold those responsible accountable in criminal trials. But to what extent do such trials affect public confidence, and how does the role of tr
Advancements in the application of international refugee laws, European Union and national asylum legislations has increased the protection for refugees and asylum seekers from sexual minorities. With point of departure in the German administrative court's credibility assessment dealing with asylum/refugee appeal cases relating to sexual orientation, the aim of this study is to explore the epi
