Usually the mel-frequency cepstral coefficients are estimated either from a periodogram or from a windowed periodogram. We state a general estimator which also includes multitaper estimators. We propose approximations of the variance and bias of the estimate of each coefficient. By using Monte Carlo computations, we demonstrate that the approximations are accurate. Using the proposed formulas, the
Popular Abstract in Swedish Bakterier av arten Streptococcus pyogenes kallas på svenska för grupp A streptokocker (GAS). Bakterien kan finnas hos människan utan att orsaka sjukdom (bärarskap) men också orsaka sjukdomar som t.ex. halsfluss och svinkoppor som även kallas impetigo. Detta är relativt milda infektioner men bör behandlas med antibiotika eftersom det kan uppstå följdsjukdomar en tid efteGroup A streptococcus (GAS) is one of the most common of bacterial pathogens infecting humans, frequently causing throat and skin infection. Some GAS strains have surface-expressed virulence factors called M proteins that bind human plasminogen with high affinity. Plasminogen is a central component of the human fibrinolytic system, and is bound by an M protein termed PAM through defined binding mo
The thesis is a summary of five papers on crossing and extremal properties of normal processes
Models of the engineering design process and of the development process nowadays present similar forms in the engineering design literature and interact in a similar way. These models are often presented as generic, in order to be used in a wide area of applications. This interaction is however not unproblematic, and in this publication we present some important issues and challenge the generic as

Previous collaboration research shows that problems and conflicts sometimes arise as a part of collaboration. Researchers have highlighted the importance of narratives, but have not focused on narratives about successful cooperation. This article tries to fill this gap by analyzing stories of successful cooperation, even if it unfolds during shorter interaction sequences. The aim is to analyze how
The English philosopher Richard M. Hare - one of the leading moral philosophers of the twentieth century - develops in his most recent major work an ingenious theory of moral reasoning. He maintains that there are rules of fundamental moral thinking which are determined by the concepts involved in moral thinking. Moreover, he argues that the evaluative conclusions reached by taking facts into acco
In old mnemonic systems, like the Memory Palaces (Ricci) and the Memory Circles (Llull), the general purpose is to organize and preserve the images of memory over time. However, in contemporary discussions of memory taking place within the field of trauma studies (Leys, Laub, Feldman, Caruth, van der Kolk), the focus is on the forgotten, and on understanding why we do not remember traumatic events
This study examines the management of used mobile phones in the United Kingdom between 2005 and 2008. It shows that the replacement cycle for mobile phones got shorter during the period due to heavy handset subsidies given by mobile network operators. The planned obsolescence presented a business opportunity for the exports of used phones to developing countries. However, the collection for re-use
