The problem of adversarial CNN attacks is considered, with an emphasis on attacks that are trivial to perform but difficult to defend. A framework for the study of such attacks is proposed, using real world object manipulations. Unlike most works in the past, this framework supports the design of attacks based on both small and large image perturbations, implemented by camera shake and pose variat

Purpose: Buckets containing floating reed (Phragmites australis) simulated floating treatment wetlands (FTWs) and were used to improve the remediation performance of synthetic greywater (SGW). The aim of the study was to investigate the behaviour of FTWs for treatment of key contaminants within artificial greywater. Methods: Pelletized ochre based on acid mine water sludge was introduced to select

År 2030 beräknas var fjärde person i Sverige vara 65 år eller äldre. Detta ställer stora krav på kunskapen om åldrandet och åldrandets sjukdomar och omvårdnad av äldre personer – i synnerhet när det gäller de allra äldsta. Äldre personer som bor på särskilda boenden är ofta multisjuka eller har nedsatt beslutsförmåga, i huvudsak till följd av demenssjukdom. De finns i dag goda kunskapsunderlag so

Ultrasound Doppler velocimetry was used to predict fetal well-being. The uterine artery blood velocimetry seemed to be a good predictor of perinatal outcome in high-risk pregnancies and a complement to umbilical artery velocimetry. The fetal middle cerebral artery blood velocimetry might be an early sign of fetal hypoxia. In pregnancies with decreased perception of fetal movements, the non stress

The inheritance pattern of hordein, the seed storage protein in barley, has been studied in two wild Hordeum species, H. murinum and H. pusillum. Three different diploid populations of each species were crossed, and the F1 plants were self-pollinated. The seeds with an F2 genotype were studied by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Several differences could be ob

In this thesis, I have studied male and female selective mechanisms that can affect plant reproductive success and gene flow. I have focussed on sexually selected traits, mainly pollen competition and maternal sorting mechanisms, for example through non-random ovule abortion. The main question was; what kind of traits can influence the most successful pollen donor or maternal sorting process? I fo

The high-order harmonics that are created in the interaction between an intense laser pulse (around 10¹⁴ W/cm²) and a gas medium are studied. The high-order harmonic radiation is a relatively new source of coherent radiation in the short wavelength range. The high-order harmonics are interesting for applications because of their good spatial and temporal coherence, their shor

Observations show that radial metallicity gradients in disk galaxies are relatively shallow, if not flat, especially at large galactocentric distances and for galaxies in the high-redshift universe. Given that star formation and metal production are centrally concentrated, this requires a mechanism to redistribute metals. However, the nature of this mechanism is poorly understood, let alone quanti
