Rising fuel prices and increasing environmental awareness emphasizes the importance of the transportation aspect in logistics. This calls for new improved inventory control methods that consider the effects of shipment strategies in a more realistic manner. This thesis, consisting of an introduction and three scientific papers, studies how shipment decisions can be included in the inventory contro

Partitioning large high-speed globally synchronous ASICs into locally clocked blocks reduces clock skew problems and if handled correctly it also reduces the power consumption. However, to achieve these positive effects, the blocks need on-chip clock generators having properties such as small area and low power consumption. Therefore, a low power, high frequency, small area digitally controlled on

Extreme Programming (XP) is becoming popular as a software development method and there is quite a lot of literature describing its philosophy and practices. However, in all of this literature Software Configuration Management (SCM) is almost never mentioned explicitly, leaving XP practitioners with the impression that SCM is not needed and SCM people with the impression that XP is not sound from

This thesis covers the impact of the financial crisis of 2007-2009, the non-linearity in the impact of bankruptcy risk on leverage and the effect of pessimism and doubt on the equity premium. It consists of four self-contained essays. The first essay develops a framework to investigate the impact of the financial crisis starting in 2007 and employs an extended GARCH model to test for spillover and

My dissertation studies the frequently mentioned but never fully explored affinities between the writings of Juan Carlos Onetti and Juan José Saer. From the very beginning of their writing careers, both authors relate writing and narrating to an elusive search for meaning—in life and stories. Consequently, the scene of storytelling is of the utmost importance; how, when, by and to whom, and indeed

Popular Abstract in SwedishBarnets andra levnadsår präglas till stor del av en enorm utveckling av språkliga färdigheter. Omkring ettårsåldern börjar de flesta barn säga sina första ord. Det produktiva ordförrådet (de ord barnet kan säga) växer till en början ganska långsamt, men inlärningstakten ökar successivt. Mellan 1 ½ och 2 år genomgår många barn något som brukar kallas för ”ordförrådsspurt”This dissertation investigated electrophysiological measures of individual differences in toddlers’ ability to learn novel object labels and process familiar object words and their referents. The studies measured both visual and auditory event-related potentials (ERPs) in response to pictures of objects and words in a longitudinal sample of 20- to 24-month-olds, an age of dynamic vocabulary develo

A new upper bound on the list error probability is presented. This bound is derived by combining the techniques for obtaining the tangential union bound with an improved bound on the error probability with respect to a given list. Connections between the list distance and the eigenvalues of the covariance matrix of the code are studied

We investigate the use of particle filter (PF) estimation techniques on a hovercraft vehicle in an office environment. Monte Carlo Localization (MCL) with particle filtering is a popular method for localizing robots with laser range finders. In maps featuring long, uniform corridors though, a PF can produce low confidence estimates. When used as feedback to control an unstable vehicle this can pro

Författaren Birgitta Olsson menar stick i stäv med Konjunkturinstitutets utredare att det är genom produktivitetsförbättringarna i ekonomin, som vi kan klara kortare arbetstid. Förutsättningen är dock att den genomförs som en daglig förkortning av arbetstiden och i lite snabbare takt än KI:s alternativ. Forskning visar att kortare arbetsdagar innebär en förbättring av det sociala livet. Balansen m
