Regional sex-specific rates of a rare disease often show conspicuous fluctuations over conventional strata of age and calendar time. In a cohort study, when such rates are used as references in the calculation of the expected number of cases, the accumulated person-time of the study cohort may somewhat haphazardly contribute to the result. For example, only the person-time observed in the strata w
Numerical analysis, such as the finite element method is the most used computational procedure for nonlinear deformation and strength analysis of structures. In order to obtain meaningful results the material behaviour must be described and simulated accurately. Another important element in order to perform the simulation is a robust and accurate numerical integration algorithm. The present paper
With computers embedded almost everywhere, in domestic, industrial, and medical appliances and devices, computing is becoming increasingly pervasive. Services in pervasive systems can be combined and coordinated through user-defined scripts called assemblies, a light-weight and understandable way for end users to adapt services to fit their specific needs. Previous languages for assembly scripts
Considers the close musical connections between Sweden and Germany, and how they were affected by the cultural policies of Nazi Germany in 1939-45. A wide range of topics are discussed including the reception of Swedish music in Nazi Germany, the relationship between Kurt Atterberg and Moses Pergament and national socialism, and the reaction of Swedish radio audiences to German music.
JastAddJ is an extensible Java compiler, implemented using reference attribute grammars. It has been shown previously how the language constructs of Java 5, like generics, could be modularly added to the original JastAddJ compiler that supported Java 1.4. In this paper we discuss our experiences from extending Jast- AddJ to support Java 7. In particular, we discuss how the Try-With-Resources state
The aim of this investigation is to measure the interface fracture toughness of a woven composite. For this purpose, double cantilever beam (DCB) specimens are tested to measure the load as the delamination grows. The specimen is composed of 15 layers of a carbon-epoxy, balanced weave with alternate layers containing fibers in the directions and the directions. A thin piece of Teflon is placed bet
Optimization of aerodynamic shapes using computational fluid dynamics (CFD) approaches has been successfully demonstrated over a number of years; however, the typical optimization approaches employed utilize gradient algorithms that guarantee only the local optimality of the solution. While numerous global optimization techniques exist, they are usually too time consuming in practice. In this brie
Using tritium and helium-3 data for calibration, a 2-D transport model was set up to explain the occurrence of bentazone, dichlorprop, glyphosate, isoproturon, MCPA and metamitron in a small groundwater catchment in southern Sweden. The model was parameterised with site-specific degradation and sorption data to enable transport simulations. Local climatological data and a 21-year record of agricul
The release of lactose (hydrophilic) from polymer tablets made with hydrophobically modified poly(acrylic acid) (HMPAA) have been studied and compared it to the release of ibuprofen, a hydrophobic active substance. Lactose is one of the most used excipients for tablets, but lactose release has not been widely studied. One reason could be a lack of good analytical tools. A novel biosensor with cell
The concept of multiple partonic interactions in hadronic events is vital for the understanding of both minimum-bias and underlying-event physics. The area is rather little studied, however, and current models off er a far from complete coverage, even of the effects we know ought to be there. In this article we address one such topic, namely that of rescattering, where an already scattered parton
This paper presents the incorporation of an auto-tuning real-time garbage collector into a feedback-based on-line scheduling system. The studied feedback scheduler is designed to dynamically adjust the sampling periods of a set of controller tasks in order to maximize the overall control performance. In the suggested approach, the memory management overhead is made explicit and taken into account
