Popular Abstract in Swedish HIMMELSKOMPASSEN En orienterare förlitar sig på karta och kompass för att finna sin väg genom skogen. När solen börjar gå ner blir det allt svårare att urskilja den röda kompassnålens riktning och detaljerna på kartan. Orienteraren slår slutligen på sin pannlampa och fortsätter springa mot sitt mål. Han är inte ensam. Många andra varelser har också ett mål att nå under The polarization pattern of skylight offers many animals a reference for visual compass orientation. In those cases when this optical compass is identified, the receptors involved are often confined to a small part of an eye built predominantly for other visual tasks. This thesis reports the discovery of a unique compass organ in the spider Drassodes cupreus, where a pair of specialised secondary

Subband adaptive filters have been proposed to avoid the drawbacks of slow convergence and high computational complexity associated with time domain adaptive filters. However, subband processing causes signal degradations due to aliasing effects and amplitude distortions. This problem is unavoidable due to further filtering operations in subbands. In this letter, the problems of aliasing effect an

Through an historical sociological investigation of space and time, globalization theory is found to be based in a faulty understanding of history. Globalization theory argue that a spatio-temporal shift has occurred which has transformed social reality from a territorialist Westphalian system to post-territorialism. Such an understanding is proven problematic as the historical basis for the Westp

The possibility of trade-offs in road tunnel design incorporating suppression has been evaluated. Different tunnel configurations and ventilation conditions considered to identify potential trade-offs, offering options of design alternatives for future substantial cost-benefit estimates. Suppression systems are regularly used in Australia and Japan. The interest regarding suppression systems in tu

This bachelor’s thesis is an anthropological analysis of the ghetto debate in Denmark taking place from October 2010 to April 2011. Considering the different actors in the debate; the politicians, the ethnic minorities as well as the ethnic Danish residents of the ghetto, and the Danish population in general it will become clear that the debate about ghettos is very different between those trying

This paper presents a methodology to fully characterize the dynamic range of a linear X-ray detector, usually employed to perform radiography and tomography. The proposed procedure analyzes each pixel of the detector and presents the results both in terms of general performance of the detector and as a spatial distribution of different parameters for each pixel. This method has been applied to thr

X-ray microscopy offers the opportunity to image biological and radiosensitive materials without special sample preparations, bridging optical and electron microscopy capabilities. However, the performance of such microscopes, when imaging radiosensitive samples, is not limited by their intrinsic resolution, but by the radiation damage induced on such samples. Here, we demonstrate a novel, to the

The First Submarine Flotilla is expanding. Four submarines are to become five and a new, larger signal intelligence ship is to replace the current one. At the same time many employees are on the verge of retiring and new ones in need of training arrives. It is therefore of utmost importance that the existing staff want to remain in their workplace. The purpose of this study was, through a survey b

The lifetime extension of smartphones is seen as a prominent way to reduce the environmental impacts caused during the production of the devices. Smartphones may be small devices, but their impact is no longer small as for the past years e-waste has been the largest growing waste generated globally. This research aimed to learn what perspectives Swedish smartphone users had towards repairability a

The present study reveals how the presence of relevant and irrelevant spoken language affects the processing for visual information, and if this is mediated by executive function processes that develop from childhood (N = 10, age 4-10) to adolescence (N = 16, age 14-17) and through adulthood (N = 16, age 21-28). Participants engaged in a task in which they looked at visual stimuli organized within

Automated Software testing is becoming increasingly popular, which in turn creates more information that has to be analyzed. At the software company Qlik a tool called NIOCAT is used to create clusters of failed test cases thought to originate from the same code defect. The clustering is done in order to decrease the ever increasing amount of manual analysis needed to be done with regards to softw

Purposes: The Body Awareness Questionnaire (BAQ) has been considered the best available measure of body awareness, but it is not currently available in Spanish. Methods: To address this shortcoming, a sample of 281 Spanish participants completed a survey with a Spanish version of the BAQ, as well as the Body Appreciation Scale (BAS-2), the Self-Compassion Scale-Short (SCS-S) and the New Sexual Sat

The Middle Ordovician of the palaeocontinent Baltica provides some of the best preserved and most diverse acritarch assemblages of the lower Palaeozoic. A great number of widely used acritarch genera and species have been described from this area since the 1960s and many of these taxa are considered as biostratigraphically useful for both regional and international correlation. Here, we document t

Non-linear acoustic methods has shown increasing potential in the identication of damage in brittle materials such as concrete. Commonly, these methods focus on one or several resonance frequencies of the material and on the relative change in resonance frequency and attenuation with strain amplitude which has been shown to allow one to identify the extent of the material damage. However, current

The detection of the formyl radical (HCO) is of great interest in the field of combustion research since it can provide information about the local heat release (HR) rate which is a key parameter in the understanding of combustion processes. Unfortunately, due to the low signal level, HCO planar laser-induced fluorescence (PLTF) has so far not been applicable for single-shot imaging, which is nece

Supersymmetri (SUSY) är en av de teoretiskt bäst motiverade modellerna för fysik bortom standardmodellen (BSM), och en lovande kandidat för upptäckt vid Large Hadron Collider (LHC). ATLAS-kollaborationen har utfört omfattande sökningar efter SUSY-signaturer med hjälp av data från proton-proton kollisioner i LHC, tagna under 2010, 2011 och 2012 års tid vid energier på 7 TeV och mer nyligen 8 TeV. DSupersymmetry (SUSY) is one of the best theoretically motivated beyond the Standard Model (BSM) scenarios, and a favored candidate to be discovered by the experiments at the Large Hadron Collider (LHC). The ATLAS collaboration has been extensively searching for SUSY signatures using 2010, 2011 and 2012 data from LHC proton-proton collisions at a center-of-mass energy of 7 TeV and recently at 8 TeV
