The second order random walk (RW2) model is commonly used for smoothing data and for modelling response functions. It is computationally efficient due to the Markov properties of the joint (intrinsic) Gaussian density. For evenly spaced locations the RW2 model is well established, whereas for irregularly spaced locations there is no well established construction in the literature. By considering t
The paper presents a computational model for real-time controltasks, with the primary goal of simplifying the control andscheduling co-design problem. The model combines time-triggered I/Oand inter-task communication with dynamic, reservation-based taskscheduling. To facilitate short input-output latencies, a task maybe divided into several segments. Jitter is reduced by allowingcommunication only
Popular Abstract in Swedish Att mäta det icke observerbara: Vilka chefer väljs till toppositioner? Rekrytering och urval av chefer präglas till stor del av informationsosäkerhet. Det är svårt att utvärdera chefers prestationer, då deras ansvarsområde består av så många aspekter, då de behöver stor frihet i sitt arbete och därför inte kan kontrolleras alltför mycket och då deras arbete påverkas avRecruitment and selection of managers is to a large degree characterized by information uncertainty. Managers’ performance is difficult to evaluate, as their responsibility consists of so many different aspects, as they may not always be observed due to need for freedom of action and as their work is affected by factors in their environment, which are outside of their control. Also, selection deci
The most popular approach to modelling and forecasting mortality rates is the model of Lee and Carter (Modeling and Forecasting U. S. Mortality, Journal of the American Statistical Association, 87, 659–671, 1992). The popularity of the model rests mainly on its good fit to the data, its theoretical properties being obscure. The present paper provides asymptotic results for the Lee-Carter model and
The Swedish Higher Education Ordinance states1 in Chapter 8, section 1 (Svensk Förfat- tningssamling [SFS] 1993:100) that disciplinary action can be taken against a student who “at- tempt to deceive during examinations or when academic work is otherwise assessed”. Suspicion of such behaviour is to be reported to the disciplinary board, which in turn has to establish the students intent. The main f
Growing US-Israeli tension over continued East Jerusalem settlement construction – which the White House appears unable to stop – underscores a deeper reality: The two-state solution is no longer possible. What are the alternatives? For the past few years, the idea of a “parallel states” structure has been discussed, suggesting a scenario with a two-states structure on the same land, both states c

Procedural Content Generation in Games (PCG) is a thriv- ing field of research and application. Recent presented ex- amples range from levels, stories and race tracks to complete rulesets for games. However, there is not much research to date on procedural 3D modeling of caves, and similar en- closed natural spaces. In this paper, we present a modular pipeline to procedurally generate underground
This paper provides a legal analysis and review of the European Union (EU) sustainability criteria for biofuels, presented in Directive 2009/28/EC. The paper discusses the EU sustainability criteria as a tool that could be efficiently utilized to operationalize and implement the concepts of sustainable development and sustainability in an industrial setting. The results of the analysis highlight
We investigate the next-to-leading-colour (NLC) contributions to the colour matrix in the fundamental and the colour-flow decompositions for tree-level processes with all gluons, one quark pair and two quark pairs. By analytical examination of the colour factors, we find the non-zero elements in the colour matrix at NLC. At this colour order, together with the symmetry of the phase-space, it is re
Reducing vulnerability is essential for adaptation to climate change. Compared to approaches that examine vulnerability to a specific hazard, our analysis offers an alternative perspective that conceptualizes vulnerability to climate change as a phenomenon that is independent of any specific type of hazard but relevant to multiple hazards. Vulnerability is thus a product of structural inequality a
Contrary to what is sometimes assumed, the elderly in the distant past could not always rely on voluntary care. Therefore, some of them had to develop strategies to secure assistance during old age. We focus on towns in the Low Countries, where family ties were weak, and ageing individuals likely had to plan for old age. We show how members of the middling layers of society could use wills and ret
