Energy consumption reduction is today an important design issue for all kinds of digital systems. Offering both flexibility and efficient energy management, variable speed processor architectures are prefered for low energy consumption even in hard real-time systems. For this type of systems, the main approach consists in trading speed for lower energy while meeting all deadlines. For tasks with v
This paper deals with queues and insurance risk processes where a generic service time, resp. generic claim, has the form U boolean AND K for some r.v. U with distribution B which is heavy-tailed, say Pareto or Weibull, and a typically large K, say much larger than EU. We study the compound Poisson ruin probability psi(u) or, equivalently, the tail P(W > u) of the M/G/1 steady-state waiting time W
The formation of ordered structure, such as crystallites, in starch was studied by means of differential scanning calorimetry (DSC). The influence of time/temperature treatment and additives such as polyethylene glycol (PEG), bovine serum albumin (BSA) and a carbonate buffer on the formation was investigated. The experiments were planned with a CCC (Central Composite Circumscribed) design. For all
Aerosol particles affect Earth’s climate system by scattering and absorbing light. The perturbation of the climate system caused by a change in aerosol configuration due to anthropogenic emissions has recently improved. However, the radiation balance and hydrological cycle of Earth are also highly influenced by clouds: a small change in cloud configuration can have a large effect on the climate. C
Svensk sammanfattningEfter mer än 50 år av utforskande av rymden och studier av ett växande antal kända nedslagskratrar på jorden så har bildandet av nedslagskratrar utvecklats från att anses vara en sällsynt geologisk företeelse till en fundamental del av jordens, och solsystemets, historia.I dag vet vi att nedslagskratrar är en av de vanligaste landformerna på himlakroppar i inre solsystemet, saImpact cratering was once considered a rare geological process of no, or little, importance to the evolution of the Solar System and planet Earth. After more than 50 years of space exploration and the discovery of numerous (~190 as of October 2016) impact structures on Earth, this view has changed, and it is now clear that impact craters are in fact one of the most common morphological features on
The Beamline for European Materials Engineering Research (BEER) will be built at the European Spallation Source (ESS). The diffractometer utilizes the high brilliance of the long-pulse neutron source and offers high instrument flexibility. It includes a novel chopper technique that extracts several short pulses out of the long pulse, leading to substantial intensity gain of up to an order of magni
The purpose of this article is to address issues of artistic knowledge and artistic learning by way of studying, through a concrete exemplification, the meanings and implications of linguistic metaphor in artistic and educational conceptualizations of spoken theatre. Professional artists and pedagogues in this field habitually use the concept of musicality to point to key qualities in actors’ arti
Change has often been said to characterise retailing, and research on retail change is extensive. However, though much of that research has focused on retail formats, it has not sufficiently addressed the fluid nature of retailing and how its formats emerge. This paper offers a more dynamic conceptualisation of retail format change by introducing the concept of retail formation. Taking a construct
Efficacy of human papillomavirus (HPV) vaccines promises to control HPV infections. However, HPV vaccination programs may lay bare an ecological niche for non-vaccine HPV types. We evaluated type-replacement by HPV type and vaccination strategy in a community-randomized trial executed in HPV vaccination naïve population. Thirty-three communities were randomized to gender-neutral vaccination with A
In the pp→tt¯ process the angular distributions of top and anti-top quarks are expected to present a subtle difference, which could be enhanced by processes not included in the Standard Model. This Letter presents a measurement of the charge asymmetry in events where the top-quark pair is produced with a large invariant mass. The analysis is performed on 20.3 fb−1 of pp collision data at s=8TeV co
Geophysical methods provide important information for mapping the subsurface. In semiarid areas, a detailed knowledge of the aquifers geometry can assist to a better management of groundwater. In the Valle Alto (Bolivia), which is a semiarid region, there is gap in the knowledge about the aquifer system geometry and hydrogeological processes. Local reports indicated problems in some wells such as
The aim of this paper is to contribute to an actantial approach to building type studies through a study of the visitor centre and its role in contemporary spatial production. The article takes its empirical departure in the (from a Swedish perspective) intense urbanization of the Scania region, in the southern part of Sweden. Looking at building types in terms of actants implies that different se
Oxidation of dissolved sulfur dioxide, SO2·nH2O, HSO3– and SO32–, by hexaaquathallium(III) has been studied in acidic aqueous solution with ionic strength 1.0 mol dm–3 at 25 °C. The stoichiometry of the reaction has been determined: [Tl(H2O)6]3++ SO2(aq)+ 2H2O →[Tl(H2O)6]++ HSO4–+ 3H+. The kinetics has been studied by use of stopped-flow spectrophotometry under pseudo-first-order conditions with eOxidation of dissolved sulfur dioxide, SO2·nH2O, HSO3– and SO32–, by hexaaquathallium(III) has been studied in acidic aqueous solution with ionic strength 1.0 mol dm–3 at 25 °C.

Despite the importance of canon law in the life of the Eastern Orthodox Churches, there has not been a study of the ecclesiology of the canons regulating marriage. Marriage is an object of right regulated both by civil law and the canon law of the Eastern Orthodox Church. Marriage as an object of right is at the intersection of two legal orders - the ecclesial and the civil. The canonical regulati
