Svenska elitidrottares mentala träningsvanor undersöktes genom en webbaserad enkätundersökning som besvarades av 47 aktiva idrottare (28 män, 19 kvinnor, ålder 16-37, M=25) inom fotboll, friidrott, handboll, ishockey och tennis. Studien visade att svenska elitidrottare i genomsnitt ägnar 41 minuter i veckan åt olika mentala träningsformer, dock med stor individuell spridning. Mängden mental träninThis paper aimed to study to what extent Swedish elite athletes engage themselves in psychological skills training (PST). The study was conducted through a web-based survey with 47 respondents (28 men, 19 women, age 16-37, M=25) from five sports; handball, ice hockey, soccer, tennis and track and field. The results showed that the athletes spend on average 41 minutes a week on different types of m

Misuse resilience is an important security criterion in the evaluation of the NIST Post-quantum cryptography standardization process. In this paper, we propose new key mismatch attacks against Kyber and Saber, NIST's selected scheme for encryption and one of the finalists in the third round of the NIST competition, respectively. Our novel idea is to recover partial information of multiple secret e

This paper describes a set of methods to link entities across images and text. As a corpus, we used a data set of images, where each image is commented by a short caption and where the regions in the images are manually segmented and labeled with a category. We extracted the entity mentions from the captions and we computed a semantic similarity between the mentions and the region labels. We also

We will in this paper present methods and algorithms for estimating two-view geometry based on an orthographic camera model. We use a previously neglected nonlinear criterion on rigidity to estimate the calibrated essential matrix. We give efficient algorithms for estimating it minimally (using only three point correspondences), in a least squares sense (using four or more point correspondences),

The state of the art for large database object retrieval in images is based on quantizing descriptors of interest points into visual words. High similarity between matching image representations (as bags of words) is based upon the assumption that matched points in the two images end up in similar words in hard assignment or in similar representations in soft assignment techniques. In this paper w

The thesis consists of an introduction and the following four papers: Paper I: Using resultants for SAGBI basis verification in the univariate polynomial ring. Authors: Anna Torstensson, Victor Ufnarovski and Hans Öfverbeck. Abstract: A resultant-type identity for univariate polynomials is proved and used to characterise SAGBI bases of subalgebras generated by two polynomials. A new equivalent

BACKGROUND: Tumor development requires angiogenesis, and antiangiogenesis has been introduced in the treatment of cancer patients; however, how the cardiovascular phenotype correlates with cancer risk remains ill-defined. Here, we hypothesized that vasoactive peptides previously implicated in angiogenesis regulation predict long-term cancer risk.METHODS: We measured midregional proatrial natriuret

OBJECTIVE: To assess the reliability of knee extensor and flexor muscle strength measurements in persons with late effects of polio. DESIGN: A test-retest reliability study. SUBJECTS: Thirty men and women (mean age 63 (standard deviation 6.4) years) with verified late effects of polio. METHODS: Knee extensor and flexor muscle strength in both lower limbs were measured twice 7 days apart using a Bi

Popular Abstract in Swedish Denna avhandling presenterar resultat från experimentella studier av tensiders och enzymers beteenden vid modellytor. Ellipsometri var den i huvudsak använda tekniken i dessa undersökningar. Studier av tensidadsorption i statiska och dynamiska vätningssituationer initierades för att undersöka adsorptionsbeteenden i närheten av trefaslinjen under dynamisk vätning. I falThis thesis presents results from experimental studies of the interfacial behaviour of surfactants and enzymes at model surfaces. The main technique used throughout the work was ellipsometry. Studies of surfactant adsorption in static and dynamic wetting situations were performed to investigate adsorption behaviour close to the three-phase contact line (tpl) during dynamic wetting. It was demonst

To be able to determine the position of a static object in 3D space by means of computer vision, it has to be seen by cameras from at least two different view points. The same applies for measuring the position of a moving object based on images captured at one single time instant. However, if the cameras are not synchronized in time, or if a moving object is not visible in all images, one can not

Motivation: Dynamical models describing intracellular phenomena are increasing in size and complexity as more information is obtained from experiments. These models are often over-parameterized with respect to the quantitative data used for parameter estimation, resulting in uncertainty in the individual parameter estimates as well as in the predictions made from the model. Here we combine Bayesia

Security has been recognized as a leading barrier for IoT adoption. The growing number of connected devices and reported software vulnerabilities increases the importance firmware updates. Maturity models for software security do include parts of this, but are lacking in several aspects. This paper presents and evaluates a maturity model (HAVOSS) for handling vulnerabilities in third party OSS and

Massive MIMO is a promising technology to connect very large numbers of energy constrained nodes, as it offers both extensive spatial multiplexing and large array gain. A challenge resides in partitioning the many nodes in groups that can communicate simultaneously such that the mutual interference is minimized. We here propose node partitioning strategies that do not require full channel state in

The Learning with Errors problem (LWE) has become a central topic in recent cryptographic research. In this paper, we present a new solving algorithm combining important ideas from previous work on improving the BKW algorithm and ideas from sieving in lattices. The new algorithm is analyzed and demonstrates an improved asymptotic performance. For Regev parameters q = n^2 and noise level \sigma = n

Uppsatsens teoretiska ramverk innefattar teorier kring reality-tv, genus och könets performativitet i reality-tv. Baserat på studiens analys kunde

Det har visat sig att fysisk aktivitet minskar risken för en rad olika sjukdomar. Studien syftade till att undersöka fysisk aktivitet i olika kontexter och på olika nivåer för att bidra med ny kunskap om eventuella hälsofördelar med fysisk aktivitet. Då det är betydelsefullt för organisationens effektivitet och produktivitet att de anställda mår bra är det också viktigt att organisationen arbetar Physical activity has been shown to reduce the risk of several illnesses. The study aimed to investigate physical activity in different contexts and on different levels to contribute with new knowledge about possible health benefits linked to physical activity. Since the health of the employees is crucial for the organization’s efficiency and productivity it is important that organizations promote

Den 30 oktober 2014 erkände Sverige Staten Palestina. Syftet med denna uppsats är att utifrån en folkrättslig metod undersöka de migrationsrättsliga konsekvenserna av detta. De frågor som aktualiseras i detta sammanhang är vilka som nu kan bedömas vara palestinska medborgare samt hur artikel 1 D och 1 C i flyktingkonventionen ska tillämpas till följd av erkännandet. Medborgarskapet får betydelse On October 30, 2014 Sweden recognized the State of Palestine. The purpose of this essay is to examine the legal consequences of this in the field of migration law by applying an international legal method. The questions arising in this context are which individuals that can be considered to be Palestinian citizens and how Article 1 D and 1 C in the Refugee Convention should be applied as a result
