In computer-vision feature extraction algorithms, compressing the image into a sparse set of trackable keypoints, empowers navigation-critical systems such as Simultaneous Localization And Mapping (SLAM) in autonomous robots, and also other applications such as augmented reality and 3D reconstruction. Most of those applications are performed in battery-powered gadgets featuring in common a very st
Popular Abstract in Swedish Olika former av ljus har använts i åtminstone 5000 år i medicinska sammanhang. Man har i många tidiga kulturer använt solljus för att behandla olika sjukdomar. Under det senaste århundradet har användandet av ljus introducerats i den västerländska medicinen. Nya former av ljusterapi har införts. Med utvecklingen av lasern på 1960-talet dök nya användningsområden upp. LaSome aspects on the use of light for tissue characterization and treatment of malignant tumours are discussed within this thesis. The work presented aims at improving optical techniques for tissue characterization, especially to detect malignant and pre-malignant lesions. A knowledge on the interaction between light and tissue is of utmost importance to understand and improve the various technique
Dissolved organic matter (DOM) drives many fundamental biogeochemical processes (e.g., carbon storage, nutrient cycling, and soil development) in forest soil. However, the molecular-level characteristics of DOM derived from different types of tropical forest soils are poorly understood. Here, water samples at different soil depths (0, 20, and 40 cm) from tropical legume (Acacia auriculiformis, AA)
The X-ray flux provided by X-ray free-electron lasers and storage rings offers new spatiotemporal possibilities to study in-situ and operando dynamics, even using single pulses of such facilities. X-ray Multi-Projection Imaging (XMPI) is a novel technique that enables volumetric information using single pulses of such facilities and avoids centrifugal forces induced by state-of-the-art time-resolv
In the active exploration of novel biobased semicrystalline polyesters to replace petrochemical plastics, AB-type aromatic condensation polymerizations are relatively rarely investigated but gain growing attention due to the straightforward synthesis of AB-type monomers from diverse asymmetric biobased feedstocks. However, achieving high molecular weights through AB-type melt polycondensations is
Efficient CAD tools are desired to reduce the increasing design efforts when algorithms implemented on ASICs are getting more complicated. For microprogrammed accelerator design, a control unit synthesizer is of great importance since the manual design of a controller for a complicated task requires substantial effort. While a hardware specific implementation results in higher performance or lower
Even though insects have comparably small brains, they achieve astoundingly complex behaviors. One example is flying moths tracking minute amounts of pheromones using olfactory circuits. The tracking distance can be up to 1 km, which makes it essential that male moths respond efficiently and reliably to very few pheromone molecules. The male-specific macroglomerular complex (MGC) in the moth anten
Popular science summary Is the European hake “shrinking” under the current fishing practices? Did you know that the current fishing practices have caused significant declines in body size of many exploited fishing stocks? This effect of fishing management has become one of the major threats for commercially exploited fish species and it can have severe negative consequences for the offspring of
Den ökade globaliseringen har bidragit till att alltmer gränsöverskridande verksamhet utövas av internationella koncerner. Förekomsten av skatteplanering för att undgå en hög skattesats har således ökat, vilket även orsakat att staternas skattebaser rubbats. Som en reaktion på de ökade gränsöverskridande aktiviteterna har internationella samarbeten etablerats i syfte att minska missbruk av de natiThe increasing globalization has contributed to more cross-border transactions exercised by multinational enterprises. To avoid high tax rates the number of tax planning activities has grown, which has caused base erosion and profit shifting for many states. In response, international collaborations have been established with the purpose to reduce tax evasion and utilization of national legislatio
Många av våra städer har problem med luftföroreningar och det har visat sig orsaka en hel del skador på människors hälsa. Det finns olika typer av luftföroreningar, vissa är gasformiga luftföroreningar som NOx eller marknära ozon och andra luftföroreningar partiklar. NOx bildas vid höga temperaturer från förbränningsprocesser som i en bilmotor. Marknära ozon form i kombination med NOx, kolväten ocMany of our cities have problems with air pollution and it have been shown to cause a lot of damage to human health. There are different kinds of air pollution, some are gaseous air pollutions like NOx or ground-level ozone and other air pollutions are particles. NOx forms in high temperatures from combustion processes like in a car motor. Ground-level ozone form in combination with NOx, hydrocarb
Object detection technologies, represented by face detection system which has been studied for a long time, have developed recently because of the development of technologies of high performance computing and pattern recognition technique. Especially, pedestrian detection system has gathered attention recently, and it will be applied to an automobile safety system and monitoring camera system. Whi
In modern batch plants, alarm floods overwhelming the operator is a common problem of ever increasing severity. As plant hardware increase in complexity and performance, measures such as downtime and meantime between failures, increase in importance and the need for a well-functioning exception handling routine therefore grows critical. In order to minimize downtime and hence boost production effi
Mukund Kabbe Oligodendrocyte differentiation in development and disease Oligodendrocytes (OLs) are cells that reside in the brain and spinal cord (collectively called the central nervous system (CNS)). They wrap the axons of neurons with a lipid-rich substance called myelin. Functionally, the myelin sheath around the axon is similar to the insulation around wires for electrical devices. It prov
Thesis Purpose: The main purpose of this study is to investigate what ideals lead consumers produce through the adoption of subjective positions that they offer to consumers. Thus, the research aims to contribute to existing theoretical knowledge of the production of consumer subjectivities. Methodology: This present study adopts an ontological relativism position, followed by a social constructio
Industry 4.0 can be described as the next generation-factories that is characterised by putting a high demand for automation and flexible production lines. The proposed way to achieve this goal is through a large number of Industrial IoT devices(IIoT) in the factory, some having high availability- and low-latency requirements. This demands for a software that can monitor and manage the application
Statistisk Analys och Modellering av ”Fuktsinnet”- Insekternas Sjätte Sinne Statistisk analys och modellering av bananflugors rörelse med syftet att undersöka hur de reagerar på fukt. Arbetet visar hur flugors beteende kan undersökas genom att analysera deras rörelse och hur skillnader i beteende kan simuleras med en statistisk modell. Sjätte sinnet finns i verkligheten, men hos insekter. De harAnimals are impacted by the humidity of their surrounding environment, it affects their ability of thermoregulation, water retention and their overall well-being. For small insects the effects of the surrounding humidity is even more important as they have a limited water storage which depletes faster in a drier environment. Some insects such as the vinegar fly Drosophila melanogaster have develop
To develop treatments for currently uncurable neurological disorders, more knowledge is needed of the involved neural circuits and changes in gene expression. The padlock probe technique, in which linear DNA probes are circularized and amplified when hybridized to their cDNA target sequence, has previously been used for both multiplexed gene detection and neuronal projection mapping in brain tissu
In this project particle production as a function of transverse momentum (\(p_{\rm T}\)) in proton-proton collisions at a center-of-mass energy (\(\sqrt{s}\)) of 7 TeV and 13 TeV has been studied. The transverse momentum is interesting to study since it reflects momentum created in the collision (before the collision, all momentum is in the beam - going in a longitudinal direction) and therefore g
