In this paper, we discuss the internet low bit rate codec (iLBC) with an emphesis on the frame-independent longterm prediction. The frame-independent long-term prediction is a method to exploit pitch-lag correlations in the encoding of speech without suffering multiple-frame speech degradation in connection with transmission loss. We present mean opinion scores for the iLBC codec and show by means

The subject who understood. The Swedish Reformation discourse and the early modern process of integration The thesis concerns why it in the discourse of the Reformation was so important to repeat statements about the need for Christendom to go back to its true heritage and that the sermon should be understood by everyone, and the statements consequences for the possibility of formulating order, co

In the research on two of the most prominent persons among those who rescued Jews from the Holocaust, Oskar Schindler and Raoul Wallenberg, a reappearing purpose has been to separate mythical, and therefore more or less false, elements in the story from the true, and implicit, academic historical writing. However, during the last decades, it has been obvious that history is not only, and sometimes

Popular Abstract in Swedish Vilken musiksmak har blodceller? Forskningen som presenteras i denna avhandling undersöker och drar nytta av hur olika celler uppför sig när de utsätts för ljud. På samma sätt som människor uppskattar olika sorters musik så reagerar olika typer av celler annorlunda beroende på vilka ljud de utsätts för. Cellerna är dessutom ganska konservativa. När de utsätts för ett vOver the last decades the ongoing work in the fields of Lab-on-a-Chip and Micro-Total-Analysis-Systems has led to the discovery of new or improved ways to handle and analyse small volumes of biofluids and complex biosuspensions. The benefits of working on the microscale include: miniaturization of the analysis systems with less need for large sample volumes; temporal and spatial control of suspend

In this paper we propose a framework for the testing of system-on-chip (SOC), which includes a set of design algorithms to deal with test scheduling, test access mechanism design, test sets selection, test parallelization, and test resource placement. The approach minimizes the test application time and the cost of the test access mechanism while considering constraints on tests, power consumption

For a stationary two-dimensional random field evolving in time, we derive the intensity distributions of appropriately defined velocities of crossing contours. The results are based on a generalization of the Rice formula. The theory can be applied to practical problems where evolving random fields are considered to be adequate models. We study dynamical aspects of deep sea waves by applying the d

An analysis of long-term fading properties of 4×4 CW MIMO channels is presented in this paper. The main focus has been on the long-term variability of MIMO channels in urban cellular environments, with emphasis on the decorrelation distance over mid range distances along the mobile trajectory for different base station antenna heights. A model that characterizes the decorrelation distance at diffe
