The paper treats the Wigner distribution of scalar-valued stochastic processes defined on R-d. We show that if the process is Gaussian and weakly harmonizable then a stochastic Wigner distribution is well defined. The special cas, of stationary processes is studied, in which case the Wigner distribution is weakly stationary in the time variable and the variance is equal to the deterministic Wigner
Degradation of organic matter takes place in many processes within a wastewater treatment plant (WWTP). The need for optimisations and extended degradation processes for both organics and nitrogen will increase as outlet demands are strengthened and increasing loads are desired. The purpose of this work was to study the degradation of organic matter at WWTPs within two areas in particular; 1) d
Implementing collaborative change initiatives in supply chains presents various challenges. This paper proposes a framework for identifying potential risk and gain sharing challenges in collaborative change initiatives, and uses the framework to explore risk and gain sharing in an interorganisational implementation of radio frequency identification (RFID) technology. The proposed framework is base
Som tonsättare upplevde jag starkt skillnaden av att komma från konsertsalen till operasalongen. I konsertsalen står det autonoma verket i fokus, men i operasalongen är det handlingen. Dessutom var skillnaden påtaglig i att planera ett verk inom ett konsertprogram för mindre än 100 lyssnare till att tänka sig 1000 lyssnare och att man ensam ska fånga intresset en hel kväll. I min konstnärliga avha
Vem talar samhället till genom utformningen av staden och arbetsdelningen mellan könen? Hur framställs konsumenten i köpcentrumet? Hur tar sig utsatthet uttryck i staden och hur upplever kvinnor stadens rum nattetid? Speglingar av rum – om könskodade platser och sammanhang samlar aktuell forskning om rummet som könskodat. Utgångspunkten är platsens och rummets betydelse som en fysisk materiell v
Water and salt mass balances for the Dead Sea were modeled. Precipitation, evaporation, river discharges, ground water flows, input/output from potash companies and salt production, and brine discharge were included in the models. The mixing time in the Dead Sea was modeled using a single-layer (well-mixed) a two-layer (stratified) system. Using the single-layer approach the water level was predi

The thesis is concerned with topics relating to auctions and competitive bidding. In the first chapter, the case of a procurement situation where multiple producers compete in price and quality, but are unable to commit to quality, is treated in a scoring auction context. An optimal scoring rule, for a buyer able to comittto a rule, is characterised. The second chapter is concerned with auction
About narration and memory in Lars Gustafsson’s novel "Windy berättar" (1999).
A novel multitaper spectrogram estimator for Gaussian func- tions is proposed. The multitapers are the Hermite functions and a fixed number of few multitapers are used in the estimate. The weighting factors of the different spectrogram functions are optimized to give the approximative Wigner distribution for the Gaussian function. The performance of the estimator is investigated in terms of resolu
In the Middle Ages, there was an Augustinian monastery in Dalby (Scania). The article gives an overview of what we know about it, concentrating in particular on the foundation of the community c. 1070, the medieval organization of the Augustinian "Order", and the mode of life of Augustinians. The article includes an artistic representation by Petter Lönegård of what the monastery and its church (t
Several cell types and nerve tissue have been studied using a combination of microcalorimetry and other methods. The heat production rate and its pH dependence of normal and transformed 3T3 cells were studied. The transformed cells manifested a higher heat production rate and a larger anaerobic contribution to the total catabolism than did the non-transformed cells. Moreover, the transformed cell
