Recent work in multiple view geometry has focused on obtaining globally optimal solutions at the price of computational time efficiency. On the other hand, traditional bundle adjustment algorithms have been found to provide good solutions even though there may be multiple local minima. In this paper we justify this observation by giving a simple sufficient condition for global optimality that can
We describe the characterization of the hydrodynamic properties of anisotropic magnetic nanoparticles using a combination of transmission electron microscopy (TEM) and dynamic as well as depolarized dynamic light scattering (DLS/DDLS). The particles used are nearly monodisperse hematite spindles with an average length of 280 nm and a minor axis of 57 nm, coated with a layer of silica of variable t
This report presents a large number of optimal PI and PID parameters for a batch of 134 benchmark process models representative for the process industry. This information can e.g. be used as a reference for other controller design methods. The optimal parameters have been derived using the MATLAB®-based software called SWORD, which determines the PI or PID controller that gives the best load distu
In this article, we report a functionalised ZnO-nanorod-based selective electrochemical sensor for intracellular glucose. To adjust the sensor for intracellular glucose measurements, we grew hexagonal ZnO nanorods on the tip of a silver-covered borosilicate glass capillary (0.7 mu m diameter) and coated them with the enzyme glucose oxidase. The enzyme-coated ZnO nanorods exhibited a glucose-depend
The usage of industrial robots for milling tasks is limited by their lack of absolute accuracy in presence of process forces. While there are techniques and products available for increasing the absolute accuracy of free-space motions, the mechanical weaknesses of the robot in combination with the milling forces limits the achievable performance. If the dynamic effects causing the deviations can b
Firms in local industries maintain their capability to generate new export varieties by simultaneously exploiting internal and external knowledge resources. The paper introduces the notion variety triplet' to distinguish individual export varieties, where a triplet is a unique combination of a firm, a product code and a destination country. For each date, the set of variety triplets in each local
We present how dramatically the nonequilibrium nature of an oppsitely charged polyelectrolyte/surfactant mixture can affect the interfacial properties. We show for the first time that the cliff edge peak in the surface tension of the poly(diallydimethylammonium chloride)/sodium dodecyl surfate system is produced as a direct result of depletion of surface-active material from the bulk solution due
Object tracking algorithms and motion triggered alarms are often dis- turbed by shadows. It is challenging to separate between moving objects and shadows since they have similar movement patterns and image prop- erties. In this thesis, three different approaches to detect shadows are developed and evaluated. The identified shadows determine what parts of the image not to track and what alarms to i
Studien berör användningen av sociala kategorier i polisiär och statlig verksamhet, och visar att social kategorisering leder till en rad problematiska konsekvenser. Efter uppmärksammandet av polisens så kallade Romregister uppstod en debatt om polisens arbetsmetoder och huruvida fördomar förekom inom den polisiära organisationen. Polisiära och statliga insatser som riktar sig mot en särskild grupThis thesis discusses the use of stereotypes and social categories in the police force. The study illustrates how stereotypes inevitably lead to several problematic consequences. Following the uncovering of the so called ”Romani-register”, a debate occurred whether stereotypes existed in the Swedish police force. Targeted police efforts and government initiatives are however a consequence of the c
This report contains a description of the fire protection status of nursing home Linnéagården in Gislaved, Sweden, with a focus on evacuation possibility for the people living there. The building design is compared to the rules of fire safety implementation in the Swedish building code. Evacuation calculations and simulations are based on the computer programs Argos (smoke spread etc.) and ERM (Ti
Iggesund Paperboard Limited works in an increasingly competitive and cost-focused industry. The production is very customised and besides the different product variants some customers also have special requests, which mean activities that fall out of the normal process. The contribution system does not identify the additional costs that depend on the special customer requests. The purpose with th
BACKGROUND: In patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) and who are treated with direct oral anticoagulants (DOACs), dual antithrombotic treatment without aspirin is recommended. Evidence comparing P2Y 12 inhibitor strategies in this setting is limited. AIMS: This study aimed to compare outcomes with ticagrelor versus clopidogrel as part of
Thermal actions have a signicant eect on bridge structures and can at some sections account for more than 20% of the reinforcement. Such actions are especially important in certain types of concrete bridges, e.g. portal frame bridges. Thermal actions dier from other load types considered during bridge design through being a constraining load. A temperature prole can be divided into a uniform part
Abstract The aspiration of this essay was to search for explanations why children who are victims of sexual abuse don´t tell someone immediately about their horrifying experiences. Commonly, their way of dealing with the trauma is instead silence for many years until they decide to reveal the abuse. I have read four autobiographies written by people who were themselves, when they were children, vi
Tall buildings have lately become a problem to design because of the development of light weighted steel frames and wind loads. An important task of a structure is the absorption of horizontal loads and the capacity to transfer the resulting moment down into the ground. It is the engineer’s task to make sure that the structure’s performance is sufficient when it comes to safety and serviceability.
Beginning with researching past, present and future tent structures, analyzing the tent market and the use of party tents, the initial aim of creating a truly modular party tent that is suited for its purpose was processed, discussed and refined into four design directions. With help from a thorough function analysis and evaluation, a winning direction was chosen and developed further. With help f
The potential of embryonic stem cells to differentiate to all cell types makes them an attractive model for development and a potential source of cells for transplantation therapies. Candidate approaches have identified individual genes and proteins that promote the differentiation of embryonic stem cells to desired fates. Here, we describe a rapid large-scale screening strategy for the identifica
The abeyance of self-consciousness (SC) during hypnosis has beendiscussed as a central aspect of hypnosis, yet dispositional SC hasbeen very rarely evaluated as a correlate of hypnotizability. In thisstudy (N = 328), the authors administered the Harvard Group Scaleof Hypnotic Susceptibility (HGSHS), the Inventory Scale of HypnoticDepth (ISHD), and the Self-Consciousness Scale-Revised (SCS-R).Women
