Abstract in UndeterminedA numerical study has been performed to simulate the tip leakage flow and heat transfer on the first stage of a high-pressure turbine, which represents a modern gas turbine blade geometry. The low Re k-ω (SST) model is used to model the turbulence. Calculations are performed for both a flat and a squealer blade tip for three different tip gap clearances. The computations we
Temat “Retorik och lärande” fångar den pedagogiska dimensionen av retoriken som ett undervisningsämne. Historiskt har utgångspunkten varit de retoriska övningarna, progymnasmata. Min översättning av Afthonios progymnasmata publicerades 2002 under titeln Retoriska övningar. I mina kurser har vi återupptagit dessa övningar så att studenterna gradvis lär sig retorikens grunder. Övningsserien bygger p
The transcription factor Wilms' tumor gene 1 (WT1) is highly expressed in the majority of leukemias, suggesting a role in leukemogenesis. Acquired WT1 mutations are reported as an independent predictor of poor clinical outcome, and mutations resulting in deletion of the entire DNA-binding zinc-finger domain (WT1delZ), is the most common type. The aim of this study was to study cellular effects of
Purpose: To explore how the rehabilitation plan influences the rehabilitation process and its outcome in people with late effects of polio participating in an individualised goal-oriented interdisciplinary rehabilitation programme. Methods: Four women and two men with late effects of polio were interviewed before rehabilitation, at discharge, and at follow-up. Data were analysed according to the c
This chapter addresses the control of glucose feeding in fed-batchreactors. The feeding strategy is based on a pulse technique, whichdoes not require a priori knowledge of the process. A feedbackalgorithm optimizes the feed rate with respect to the constraints ofaerobic conditions and overfeeding. Stability and performance analysisare performed on a simplified model of the reactor, using standard
While research on the design of heterogeneous concurrent systems has a long and rich history, a unified design methodology and tool support has not emerged so far, and thus the creation of such systems remains a difficult, time-consuming and error-prone process. The absence of principled support for system evaluation and optimization at high abstraction levels makes the quality of the resulting im
The Java programming language, being a portable and safe object-oriented language, has gained much interest among embedded and real-time systems developers. However, standard Java implementations exhibit problems with performance, memory footprint, and predictability. The question is then, are these limitations inherent in the technology? Reviewing run-time aspects and the possibility to compile
The study frames a traditional industry in transition with the aim to understand the ways in which a work-identity is formed in the service economy along the west coast of Sweden. More specifically, we want to understand how diversified inshore commercial fisheries are discursively established and negotiated as a service enterprising subject in three everyday relationships; authorities, customers
Today’s multimedia and DSP applications impose requirements on performance and power consumption that only custom processor architectures with SIMD capabilities can satisfy. However, the specific features of such architectures, including vector operations and high-bandwidth complex memory organization, make them notoriously complicated and time consuming to program. In this paper we present an aut
We report a novel size-insensitive method, iso-acoustic focusing (IAF), that can, for the first time, analyze and separate cells based on their intrinsic acoustic properties. We characterize the IAF system using two different cell lines and apply it to measuring the acoustic impedance of two subgroups of white blood cells (WBC): neutrophils and lymphocytes. We find cell type specific differences i
Increased physical activity can have health benefits among inactive individuals. In Sweden, the healthcare system uses physical activity on prescription (PAP) to motivate patients to increase their physical activity level. Mindfulness may further heighten the internal motivation to engage in physical activity. However, previous research has not demonstrated clear evidence of such an association.AI
On 18 August 2022, an extremely very local 45 minutes storm fell over Båstad. There are several observations close to or more than mm. In the summer 1937 there was a famous long-lasting rain, for which the daily value was 150 mm. During the summer 2007, there were many large rainstorms of around 75 mm. I compare the short-term 2022 storm with other large storms observed in Sweden, and I do the sam
Serier av dygnsnederbörd omfattande 89 år från Malmö, Halmstad och Göteborg har analyserats liksom dygnsnederbörd från 230 stationer i Skåne för perioden 1961–1990. Fördelning i rum och tid har undersökts liksomförhållanden mellan dygnsnederbörd och olika parametrar. Extremvärden har uppskattats med olika frekvensfördelningar. De allra största oberoende händelserna har inträffat ganska jämnt fördeSeries of daily precipitation including 89 years from Malmö, Halmstad and Göteborg have been analyzed aswell as daily precipitation from 230 stations in Skåne in the period 1961–1990. The distribution in space andtime has been investigated, and also the relation between daily rainfall and different parameters. The mostextreme independent events have occurred rather evenly distributed over Skåne, a
This paper presents a new control strategy for an underactuated two-link robot, called the Pendubot. The goal is to create stable oscillations of the outer link of the pendubot, which is not directly actuated. We exploit a recently proposed feedback control design strategy, based on motion planning via virtual holonomic constraints. This strategy is shown to be useful for design of regulators for
