This paper describes an initial attempt at the construction of a data-driven model of Swedish intonation. The study is mainly concerned with model building and prediction of the intonation patterns of accented words in a corpus of read news in Swedish. Extraction of pitch information is achieved by performing a stylization of the pitch contours. The information is used to build a model for the pre
According to film mythology, the Soviet filmmaker Lev Kuleshov conducted an experiment in which he combined a close-up of an actor’s neutral face with three different emotional contexts: happiness, sadness, and hunger. The viewers of the three film sequences reportedly perceived the actor’s face as expressing an emotion congruent with the given context. It is not clear, however, whether or not the
British strategy in the Middle East consolidated around a sustained effort to prevent any adversarial penetration into the Persian Gulf, defending its position athwart the principal lines of communication and supply between Northern Europe and British India, and to protect the newly discovered Persian oil that was used to power the Royal Navy. Since the discovery of oil in 1908 by D’Arcy’s oil exp
How human exposure levels of air pollutants are related to health status is an issue of great importance for e.g. infrastructural and urban planning. This study analysed the exposure levels of NO2 for individuals depending on their country of birth. The study was conducted within three different study areas of varying characteristics and extent to decide whether any such associations existed and i
In this paper a modification of a recently proposed model simplification method for linear time invariant parameterized models is presented. It is able to obtain models with explicit parameter dependence. The method is based on convex optimization with semidefinite constraints. Computation of the reduced model requires only the frequency samples of the full one, hence it is possible to apply the m
This paper presents a decomposition strategy applicable to DAE constrained optimization problems. A common solution method for such problems is to apply a direct transcription method and to solve the resulting non-linear program using an interior point algorithm, where the time to solve the linearized KKT system at each iteration is dominating the total solution time. In the proposed method, the s
The switches and the control circuit of Buck converter with static feedback control have been implemented in a standard digital 0.6 μm CMOS process. The control used is a direct large-signal approach, and the converter has been proven to be globally asymptotically stable using the theory of successors in combination with Lyapunov's direct method. One very important design parameter is the output r

This paper provides observations and commentary on how bioenergy was presented and communicated at the 15th Conference of the Parties (COP 15) held in Denmark in December 2009, including the main conference and side events as well as “unofficial” parallel events and activities. We can learn significantly from the experiences of COP 15 in regards to how to develop and present visions for bioenergy,
