Articulatory data collected from nine speakers each of Gothenburg and Malmöhus Swedish were used in a Functional Data Analysis (FDA) to study tongue articulation dynamics, more specifically the height and frontness of the tongue body and tip in the palatal vowels /i ̆, y ̆, u̟ ̆/. Standard z-score transformations were used for speaker normalisation. Results showed that the tongue articulation for
In this paper, we discuss the role of robustness to geometric conformity versus specificity in machine learning. The key observation made here is that object variation due to appearance and due to geometric deformation are often, for good reasons, intermixed in typical object detection applications. In the paper, we consider a whole range of differently specific object detectors. It is shown that
Popular Abstract in Swedish Smärta är en varningssignal vid vävnadskada. En speciell grupp av receptorer i huden är känsliga för skadlig stimulering och kallas för nociceptorer. Signalerna från dessa ”smärtreceptorer” leds via två fibertyper till ryggmärgen. Beröringssignaler förmedlas via andra typer. I ryggmärgen bearbetas information och skickas vidare till reflexkretsar och hjärnan. Hjärnan i Recent studies indicate that experience dependent mechanisms shape the pain system during the development. In view of that painful stimuli are rare during development it is not clear how this is accomplished. In this thesis it is confirmed, using a battery of sensory deprivations in the rat, that the development of an essential component of the pain system, the nociceptive withdrawal reflexes (NWR
Plant breeding is largely depending on the repeated selection for desirable traits. This process is both time and labour consuming, making the development of commercial plant varieties a slow and costly activity. By the use of molecular markers, analysis of the genetic constitution of plants can be performed at an early stage, providing a possibility to decrease the time and cost required for sele
The stabilization characteristics and local extinction structures of partially premixed methane/air flames were studied using simultaneous OH-PLIF/PIV techniques, and large eddy simulations employing a two-scalar flamelet model. Partial premixing was made in a mixing chamber comprised of two concentric tubes, where the degree of partial premixing of fuel and air was controlled by varying the mixin
Deformation of rocks at shallow depths (i.e., at low confining pressures) is primarily driven by the evolution of new fractures or the propagation and coalescence of pre-existing ones. In this paper, fracture evolution from inclined flaws (cuts) in a soft rock deformed under plane-strain uniaxial compression is analyzed using high-resolution digital photographs and Digital Image Correlation (DIC).
Although ethnic conflicts are an acute international problem, researchers in international relations have conducted surprisingly little research in this area. The aim with this study is to analyze one aspect of ethnic conflicts, how the elites representing ethnic groups act to make the great powers legitimize their own demands, and delegitimize the demands of the enemy by adducing to norms. In the

This paper suggests a stochastic volatility term-structure model applied to the pricing of electricity swaptions in the Nord Pool market. The volatility structure in the model is specified as a product of a time-dependent function that handles the maturity effect, and a Cox-Ingersoll-Ross process that captures the volatility smile. We employ a Fourier based approach to price electricity swaptions
This article traces the development of art cinema in Britain and particularly the role played by film director Lindsay Anderson.
Popular Abstract in Swedish Tunna skikt av olika material har en framträdande roll inom både vetenskap och teknik idag. Det bakomliggande intresset för denna typ av ytbeläggningar är främst möjligheten att kombinera egenskaper hos de tunna filmerna med övriga egenskaper från det underliggande materialet för att därigenom erhålla förbättrade kemiska, mekaniska eller elektriska egenskaper. DärutöverAtomic layer deposition (ALD) is a thin-film manufacturing process in which the growth surface is exposed to non-overlapping alternating injections of gas-phase chemical precursor species separated by intermediate purge periods to prevent gas-phase reactions. ALD is characterized by sequential self-terminating heterogeneous reactions between highly reactive gas-phase precursor species and surface-
Annotated data with role-semantic information are becoming an ever more important resource for many semantic systems. They form the core element to develop large coverage, high-performance, and reusable semantic parsers, classifiers as well as applications that include lexicography, term and information extraction, semantic processing of the web, text-to-scene conversion systems, etc. Existing exa
Jesper Svenbro’s poetry can be understood as forming a lyrical poetics. This poetics can be extracted from the many poems that focus and reflect on the ontology of poetry and language, the creation and different functions of lyrical poetry, and the question of reference. This dissertation highlights the main principles of this poetics, charts its development over time, and shows the different ways
