F1 and F2 frequencies of the vowels /i/, /a/ and /u/ were measured in speech directed to an infant and to adults. The vowels were taken from content words as well as function words. The results showed that the vowel triangles in speech to the infant were expanded compared to those in speech to adults, but only in the content words. For function words, the opposite pattern was found: adults produce
Förf:s övergripande frågeställning är vilken roll psalmerna spelar för mötet mellan människors behov och kyrkans trosbudskap i sorgesituationen. Begravningsgudstjänsten ses som mötesplats mellan ”samhällsaspekten” (mindre lyckad beteckning för det existentiella) och ”kyrkoaspekten”. Evertsson har använt Göran Gustafssons enkätmaterial från 2222 begravningsgudstjänster och gjort ett urval utifrån p
Using simple waves and six-vector formalism, the propagation of electromagnetic waves in nonlinear, bianisotropic, nondispersive, homogeneous media is analyzed. The Maxwell equations are formulated as an eigenvalue problem, whose solutions are equivalent to the characteristic directions of the wave front. Oblique incidence of plane waves in vacuum on a half space of nonlinear material is solved, g
In proposing their theories concerning the development of humans out of the higher primates, psychologists and neurologists such as Deacon, Tomasello and Donald have, each in his peculiar way, accomplished “a semiotic turn”. But these attempts leave at lot to be desired. Most notably, perhaps, they are all (with the exception of Donald, to some degree) incapable of assigning a place to the picture
International Market Driven engineering (iMDE) is an international course on innovation where Swedish and Chinese engineering students are mixed with business and design students. The course is run on a yearly basis, it is six weeks long and takes place in China. Both the development and the execution of the course is made as a joint project between the Swedish and Chinese instructors. The course
We present a framework for the solution of control and estimation problems under a signal-to-noise (SNR) ratio constraint. The framework can be used to design optimal linear controllers, based on output feedback, with two degrees of freedom: One part of the controller is placed before the communication channel and represents sensing and encoding operations. The other part represents decoding and i
One of the key factors for the success of recent energy minimization methods is that they seek to compute global solutions. Even for non-convex energy functionals, optimization methods such as graph cuts have proven to produce high-quality solutions by iterative minimization based on large neighborhoods, making them less vulnerable to local minima. Our approach takes this a step further by enlargi
