A novel adaptive beamformer employing recursively updated soft constraints for acoustic speech enhancement is proposed. The beamformer operates in a subband structure to allow time-frequency operation for each channel. As such, the processing can be viewed as a combination of weighted spatial and temporal filters. The major benefit of this recursive soft constrained beamformer is that it allows th
RGB displays effectively simulate millions of colors in the eyes of humans by modulating the relative amount of light emitted by 3 differently colored juxtaposed lights (red, green, and blue). The relationship between the ratio of red, green, and blue light and the perceptual experience of that light has been well defined by psychophysical experiments in humans, but is unknown in animals. The perc
The authors examine the effect of the core hole on several spectroscopies used to explore the conduction band of simple metals. They show that the static effect on the valence electrons is very strong and discuss under what circumstances this effect may be seen experimentally. In KLV Auger spectra a core hole is present in both initial and final states. Thus, there will be almost no dynamical effe
During the last decade the condition of life has changed in many ways for the pastoral Van Gujjar who have their winter camps in the interior of the forests of the Shiwalik foot hills of Uttar Pradesh and Uttaranchal in northern India. While the Gujjar in most of northern India are a very large and ethnically as well as religiously diversified population, the pastoral Gujjar in this particular are
A software requirements specification (SRS) is an important document that reports the result from the system requirements determination (SRD) which forms a basis for subsequent activities in the systems development process. In order to increase the knowledge base of SRS and how they could be structured nine SRSs are analyzed. The analysis aims at demonstrate similarities and differences in SRS com
Many unhealthy behaviors are created during adolescence and follow the individual into adulthood. In addition, health behaviors often occur in clusters as those who are inactive are more likely to eat unhealthy food and smoke. This makes the early foundation of healthy behaviors vital. The aim was to describe and develop an understanding of adolescents' awareness and experiences concerning health
Enligt en etablerad teori om utvecklingen av politiskt styre i Europas förflutna går beskattning hand i hand med folkrepresentation. Härskare i finansiella trångmål blev nämligen mer eller mindre tvungna att erbjuda politiska fri- och rättigheter i utbyte mot folkets bidrag till statskassan. I denna avhandling undersöker jag det rakt motsatta antagandet: är det även så att icke-skatter går hand i According to a venerable argument about the formation of political regimes in historical Europe, taxation goes hand in hand with representation, as financial needs forced rulers to trade rights for revenue. In this dissertation I explore the reverse assumption, asking whether it is the case that non-taxation went hand in hand with non-representation? I argue that early modern rulers who had access
Despite their evidently different assumptions and operationalization strategies, the concepts of Circular Economy, Green Economy and Bioeconomy are joined by the common ideal to reconcile economic, environmental and social goals. The three concepts are currently mainstreamed in academia and policy making as key sustainability avenues, but a comparative analysis of such concepts is missing. The aim
AIM: The aim of this study was to investigate to what extent individual-based extended information given to mothers from city parts of low education can improve precautions taken by them to prevent burn and scald injuries involving young children in the home and further to compare the results with a group of mothers who had not received extended information. METHODS: This intervention study, with
Popular Abstract in Swedish Den övergripande problemformuleringen i min doktorsavhandling, Kripke on Necessity: A Metaphysical Investigation, kan formuleras på följande sätt: På vilka metafysiska grunder rättfärdigar Kripke giltigheten och existensen av nödvändiga a posteriori och kontingenta a priori satser? Jag visar att Kripke-paradigmet för den metafysiska essentialismen vilar på ett fundamenI undertake a metaphysical investigation of Saul Kripke's modern classic, Naming and Necessity (1980). The general problem of my study may be expressed as follows: What is the metaphysical justification of the validity and existence of the pertinent classes of truths, the necessary a posteriori and the contingent a priori, according to the Kripke Paradigm? My approach is meant to disclose the log
Abstract--- This paper follows directly from our forthcoming paper in International Journal of Machine Consciousness, where we discuss the requirements for an artefact to be a moral agent and conclude that the artefactual question is ultimately a red herring. As we did in the earlier paper, we take moral agency to be that condition in which an agent can, appropriately, be held responsible for her
Popular Abstract in Swedish Att avstå från och att avbryta livsuppehållande behandlingar på intensivvårdsavdelningar. I mitten på 1980-talet träffade jag en 16-årig flicka, som jag kallar för Annie, som patient på en intensivvårdsavdelning. Annie var förlamad på grund av en förlossningsskada. Hon hade inte tidigare behövt sjukhusvård. Nu behövde respiratorhjälp på grund av en lunginflammation. TrMany deaths in intensive care units are preceded by decisions to withhold or withdraw life-sustaining treatment. Under what conditions are forgoing life-sustaining treatment considered appropiate, when is it optitional and when is it wrong? Relevant guidelines are essential to help medical decisionmakers, but they cannot be established only from medical knowledge. They also must be related to basi
Popular Abstract in Swedish Under senare år har produkternas roll uppmärksammats mer och mer inom miljöpolitiken. Det talas allt oftare om behovet av ett livscykeltänkande där produktens påverkan på miljön under olika faser av livscykeln blir en utgångspunkt för politiska åtgärder. I en värld där leverantörskedjorna ofta är långa och involverar aktörer i ett flertal länder kan ett livscykeltänkandOne of the noticeable trends in recent years is that products have received increasing attention in environmental policy. The focus on products and their life cycle impacts is often referred to as ?life cycle thinking?. This implies a shift away from the traditional focus on production processes and the environmental impacts of point-source pollution, towards a stronger focus on emissions from the
The thesis comprises four independent research papers and a summary that focus on two related dimensions. The first dimension focuses on the understanding of the production of health. Particularly, the question is asked whether community's stock of social capital influence individual's health. The second dimension focuses on an attempt to understand the causes of socioeconomic health inequality (S
In order to overcome the shortcomings of crash data a number of surrogate measures of safety have been developed and proposed by various researchers. One of the most widely used temporal indicators is time-to-collision (TTC) which requires the road users to be on a collision course. Road users that are strictly speaking not on a collision course actually might behave and take evasive actions as if
Background: Traumatic brain injury is a common reason not only for emergency visits worldwide but also for significant morbidity and mortality. Several clinical guidelines exist but adherence is generally low. Aim: To study attitudes toward computed tomography of the head among emergency department Change to physicians throughout the article who manage patients with trauma to the head and doctors'
Although Sweden is a northern country with fairly low outdoor temperatures most of the year, its district cooling (DC) systems are expected to expand. Some actors claim that there is potential for at least a doubling of DC in Sweden. One reason for this is that demand for cooling increases with the increased use of electronics such as computers, resulting in higher indoor temperatures from waste h
