In biometric authentication protocols, a user is authenticated or granted access to a service if her fresh biometric trait matches the reference biometric template stored on the service provider. This matching process is usually based on a suitable distance which measures the similarities between the two biometric templates. In this paper, we prove that, when the matching process is performed usin

This chapter investigates participatory sense-making within ecological sound art. The field links to “a broader set of cultural practices in which the imperial power of ‘the human’ over the rest of the world is shifting in favor of what we might call a more eco-systemic engagement” (Hogg, 2013). In summer 2018, the project sent poet Gunnar D. Hansson, composer Anders Hultqvist and ecological sound

During outdoor storage of large quantities of wood fuels, hydrocarbons are emitted into air in gas phase and leached out into the ground by precipitation. To investigate to what extent these emissions have environmental or health effects, sampling has been done on wood chip piles in an existing terminal storage situated in the south of Sweden, north east of Växjö. Sampling was done by solid phase

This article investigates solidarity as a concept and/or a norm of EU law from the perspective of functional constitutionalism. It asks how solidarity fits within the normative framework of the EU legal order if we understand this framework as being founded on a functional constitution.Under functional constitutionalism, the EU is understood as a purposive polity and the authority of the legal ord

Staging an open contest is a democratic method to choose a party leader, though its electoral consequences remain unclear. I argue that leadership contests are electorally detrimental to governing parties. Competitive contests signal intraparty policy and/or personality conflict to voters, which damages governing parties’ perceived unity as well as competence in the policy-making process. Thus, le

A reconstructed human epidermis (RHE) model, the EpiDerm, was investigated and compared to human skin ex vivo regarding tissue penetration and distribution of two chromium species, relevant in both occupational and general exposure in the population. Imaging mass spectrometry was used in analysis of the sectioned tissue. The RHE model gave similar results compared to human skin ex vivo for skin pe

What is done in the act of public intelligence disclosures? Leading up to the Russian invasion of Ukraine in 2022, US intelligence agencies engaged in an unprecedented amount of public disclosures, causing scholars and journalists to describe it as a tectonic shift in intelligence practice. Going beyond the traditional question of strategic aims related to intelligence disclosures, this article ta

This paper investigates the outcomes of small-scale egalitarian language contact in an attempt to address whether different linguistic domains exhibit different degrees of stability and resistance to convergence among cohabitant speakers of Jahai and Jedek, two closely related Aslian (Austroasiatic) language varieties spoken in northern Peninsular Malaysia. Using nonparametric Bayesian mixture mod

Millimeter-wave (mmWave) is one key enabler for high data rates in (beyond-)5G wireless communication networks. The use of directive beams and the shorter transmission range in mmWave communications make it easily obstructed or blocked by humans in dynamic real-world scenarios. Connectivity diversity, a solution to link disruption and blockage, could be achieved by deploying distributed multi-poin

Datorseende blir allt bättre, men med dess precision tillkommer en beräkningskostnad. Detta arbete undersöker hur man kan använda svagare men fler datorer, exempelvis kameror, för att implementera dagens kraftfulla algoritmer.This document describes the methods and results of our Master’s Thesis, car- ried out at Axis Communications AB. A central problem with deep neural networks is that they contain a large num- ber of parameters and heavy computations. To cope with this, our idea was to split the network into chunks large enough that they require their own core, yet small enough to not violate our memory constraints.

You might have heard the expression that the eyes are the window to the soul, but what if the eyes are also the window to the brain? What if you could see what happens in a person’s brain only by looking into their eyes? There is indeed a physical link between the eyes and the brain. The retina, the part of the eyes that is responsible for collecting incoming light, develops from a part of the b

This thesis examines and discusses the relationship between social capital and bullying in Swedish schools. The study is based on two hypotheses built on inspiration from the social capital scientists Robert D. Putnam and Bo Rothstein. Both hypotheses aim to explain how social capital is created, and may affect the level of bullying in school. The study is conducted through two separate comparativ

Tidigare studier har visat på att de geofysiska metoderna elektrisk resistivitet tomografi (ERT) och tidsdomän inducerad polarisation (IP) är användbara verktyg för att detektera non-aqueous phase liquids (NAPL). Rapsolja, som är en hydrofob organisk förening med lägre densitet än vatten, har använts i ett laboratorie-försök för att utvärdera användbarheten av ERT och IP för att detektera spridninPrevious studies have shown that the geophysical methods electrical resistivity tomography (ERT) and time domain induced polarization (IP) are appropriate tools to detect non-aqueous phase liquids (NAPL). Rapeseed oil, hydrophobic organic compound with a lower density than water, was used in a laboratory experiment to evalu-ate the usefulness of ERT and IP to detect NAPL-contaminants in the enviro

Energy security and climate change are prime political concerns in the European Union. The main instrument to combat climate change through reducing greenhouse gas emissions in the EU is the EUETS, a cap and trade system. This thesis investigates in a case study the question of how the EUETS potentially impacts European energy security. In order to analyze potential impacts, this study operational

Syftet med vår studie är att undersöka hur fyra sångpedagoger beskriver hur de förhåller sig till och arbetar med personligt uttryck, härmning och förebildning samt genrekunskap och hur deras syn påverkar samverkan mellan begreppen och metoderna. Studien är av kvalitativ art och vi har använt oss av semistrukturerade frågor för att fånga pedagogernas tankar och åsikter. Sångpedagogerna säger sigThe purpose of our study is to investigate how vocal teachers describe how they relate to and work with personal expression, imitation, demonstration, knowledge about genre and how their views affect the interaction between these concepts and methods. The study is qualitative in nature and we have used semi-structured questions to capture the teachers’ thoughts and opinions. The vocal teachers s

The purpose of this study is to investigate whether social work students experience a discrepancy between what they learned at the School of Social Studies and what they experienced in the practical field and, if so, how they describe this discrepancy and how they respond to it. The group of respondents considered of 5 students from Lund University. The study was based on qualitative interviews. T

Densification is used as a sustainable urban planning strategy in many municipalities in Sweden. This paper aims to investigate how officials at the urban planning office in Lund handles the social dimension of sustainable development in the planning process regarding densification, and the challenges and obstacles that they face. Theories of current planning ideology and norms together with theor

Over the past few years the EU has seen a surge in reports showing that analogical products of dual quality are being sold in different parts of the Union. An East – West divide has been noticed in the way that products of identical branding and packaging are of poorer quality in the Central and Eastern European shops, but not in the Western ones. The aim of the research is to investigate if the l
