Biometric technologies, such as facial and fingerprint recognition, have become widely adopted for identity verification in various applications. Palm biometrics, utilizing the unique patterns of the human palm, has gained significant attention for its accuracy and security. This thesis aims to investigate and propose a comprehensive design for certain as- pects of a contactless palm print recogniImproving Contactless Palm Print Recognition Technology Biometric technologies, such as facial and fingerprint recognition, have become widely used for identity verification in various applications. An- other promising biometric solution is palm biometrics, which utilizes the unique patterns found on the human palm for accurate and secure iden- tification. This thesis focuses on investigating and

Multiple variables determine the success of an escape response of an animal, and the rapidity of the escape manoeuvre is often the most important. Fan worms (Annelida: Sabellidae) can rapidly withdraw their tentacles, which are covered in heavily ciliated ramifications called pinnules, into their tubes to protect them from approaching threats. Here, we explore the dynamic and mechanistic features

This article looks at upcycling and the library of things from intellectual property law perspective

Aims: Internal and external triggers affect seasonal and circadian variations of myocardial infarction (MI). We aimed to assess sex differences in the common triggers of MI. Methods and results: A nationwide, retrospective, cross-sectional postal survey study was conducted. Individuals who experienced a MI during holidays and weekdays were identified through the SWEDEHEART registry. Twenty-seven p

De standardiserade mätmetoder som används för att bestämma betongs tryckhållfasthet är anpassade för mätning efter relativt lång tid, men ifall det är av intresse att bestämma betongens hållfasthet kort tid efter gjutning är dessa metoder inte helt rättvisande. Cementbaserad betong är ett av världens vanligaste byggmaterial. Den har en god förmåga att motstå tryckspänningar och är inte speciellt Concrete is a building material that is normally cast according recipes, where a larger proportion of cement in the mixture results in a faster strength development and increased ultimate strength. The compressive strength, which can be considered as the most important property of concrete, is usually measured by a standardized procedure, where a test specimen is subjected to a progressively incre

Titel: Musikens Budskap - Mytologi och folktro som tema i instrumental konstmusik Författare: Erik Valdemar Sköld Handledare: Francisca Skoogh I denna skriftliga uppsats redogör jag för bakgrunden och arbetsprocessen till tre av mina egna kompositioner vars inspirationskälla och tema är kopplat till naturen och nordisk mytologi. Frågeställningen lyder följande: vilka tillvägagångssätt inom programIn this essay, I describe the background to and work process behind three of my own compositions which are inspired by nature and Nordic mythology. I asked myself: which approaches, from programmatic music throughout history, can I use in my own work as a composer? I go through some historical examples that use references to nature, and summarise literature about program music and affects, in orde

We present novel developments for the highly efficient evaluation of complex linear response functions of a multiconfigurational self-consistent field (MCSCF) wave function as implemented in MultiPsi. Specifically, expressions for the direct evaluation of linear response properties at given frequencies using the complex polarization propagator (CPP) approach have been implemented, within both the

Industrin står för en fjärdedel av Sveriges totala utsläpp av växthusgaser. Därför är det av högsta prioritet att branschen ställer om sin produktion från fossil till förnybar. En viktig strategi för att uppå klimatmålen är att elektrifiera produktionen. En storskalig elektrifiering kräver att elproduktionen matchar elbehovet samt att elledningarna är rustade för det önskade uttaget av effekt. SkåThe industry accounts for a quarter of Sweden’s total emissions of greenhouse gases. Thus, it is a high priority that the industry exchanges its dependency on fossil fuels to renewable ones. One important strategy to meet the national climate goals is to electrify the production. An excessive electrification requires that the electricity production matches the electricity demand and that the elect

Background: Children with right ventricular outflow tract (RVOT) anomaliestypically undergo surgical repair during their first months of life and thereafter they will need one or more reoperations through their life.Aims: The overall aim was to describe health-related quality of life (HRQoL) forchildren with congenital heart disease (CHD) with a special focus on children withRVOT anomalies and to

Den globala uppvärmningen är ett faktum. Stål är ett material som används i stor utsträckning och kan på grund av dess egenskaper inte alltid bytas ut mot alternativa material. Problemet är att stålindustrin står för en betydande del av Sveriges koldioxidutsläpp. Studiens syfte är att försöka skapa en uppfattning om de klimatvinster som kan göras om traditionellt stål ersätts av fossilfritt st

Risk plays a fundamental role in scientific discoveries, and thus it is critical that the level of risk can be systematically quantified. We propose a novel approach to measuring risk entailed in a particular mode of discovery process – knowledge recombination. The recombination of extant knowledge serves as an important route to generate new knowledge, but attempts of recombination often fail. Dr

H.G. Wells’ novella The Time Machine (1895) tells the story of The Time Traveller who travels to the year 802,701. There, he encounters two evolutionary progressions of humanity. One, Morlocks, have been read as representations of Victorian workers and poor, and the other, the Elois, as representations of the aristocracy. The Time Traveller represents the middle class. The novella is often seen as

The Mediterranean lizard Podarcis lilfordi is an emblematic species of the Balearic Islands. The extensive phenotypic diversity among extant isolated populations makes the species a great insular model system for eco-evolutionary studies, as well as a challenging target for conservation management plans. Here we report the first high-quality chromosome-level assembly and annotation of the P. lilfo

The spatial distribution of major ion concentration limits the predictability of solute sport processes in field soils. Therefore, it is important to analyze solute transport with chemical reactions based on results obtained from field soils and numerical simulation. A simulation model with cation-exchange reactions was developed and applied to solute-transport analysis of an undisturbed field soi

Surveys of star-forming regions reveal that the dust mass of protoplanetary discs decreases by several orders of magnitude on timescales of a few million years. This decrease in the mass budget of solids is likely due to the radial drift of millimetre (mm) sized solids, called pebbles, induced by gas drag. However, quantifying the evolution of this dust component in young stellar clusters is diffi

We investigate the space–time picture of string evolution and hadron production in a fully string-based model for high energy collisions involving heavy-ions. We find that although the density of strings is quite large at the time of hadronization in a central heavy-ion collision, the initial overlap between them right after the collisions is not necessarily large. We also find that when including
