Anti-windup scheme for networked proportional-integral control
We propose an anti-windup scheme for a class of control problems. This class, includes networked systems, where each node contains a subsystem and each edge comprise a control action. The networked anti-windup control system is proposed to address the issues caused by integrator state saturation. We show that the suggested control scheme is input-output stable. Furthermore, we provide a numerical
Measuring next of kin’s experience of participation in the care of older people in nursing homes
Background Lack of conceptual clarity and measurement methods have led to underdeveloped efforts to measure experience of participation in care by next of kin to older people in nursing homes. Objective We sought to assess the measurement properties of items aimed at operationalizing participation in care by next of kin, applied in nursing homes. Methods A total of 37 items operationalizing partic
Local Synchronization of Two DC/AC Converters Via Matching Control
We address the problem of local synchronization of two DC/AC converters connected via a RL line in closed-loop with machine matching control by pursuing a novel approach for the assessment of small-signal stability. Our method is defined using an oblique projection. We use this Lyapunov function to obtain a local stability certificate in the neighborhood of a well-defined set of equilibria charact
Game-Theoretic Network Bandwidth Distribution for Self-Adaptive Cameras
Devices sharing a network compete for bandwidth, being able to transmit only a limited amount of data. This is for example the case with a network of cameras, that should record and transmit video streams to a monitor node for video surveillance. Adaptive cameras can reduce the quality of their video, thereby increasing the frame compression, to limit network congestion. In this paper, we exploit
Gendering Objects at the V&A and Vasa Museums
This article presents two case studies, which are the result of the application of a gendered interpretative tool to the collections at the Victoria & Albert Museum (London) and the Vasa Museum (Stockholm). Objects and their gendered narratives within the museums’ collections were researched across their lifecycle, from commission and manufacture to consumption and display in a museum setting.
Thinking with Performance : Research-Based Aesthetics in Times of Conflict and Crisis
Thinking with Performance: Research-Based Aesthetics in Times of Conflict and Crisis is an artistic research project in which I examine how to critically think with performance. My main thesis is that research-based performance uses research to respond to conflict and crisis and to create spaces for thinking where artist and audience can reflect on the represented material. As such the research-ba
Reclaim Challenge : Rethinking the Critical Impact of an Education of Performance Art in Denmark
As the Danish National School of Performing Arts merged nine schools into one institution, the momentum for establishing a national, state-funded education in performance art was missed and the continuation of “traditional” profiles within performing arts education was kept. As such, the future of performance art can be seen as a kind of “supplementary technique” to otherwise acting- and text-base
Look-Locker FAIR TrueFISP for arterial spin labelling on mouse at 9.4 T
Pulsed arterial spin labelling remains a non-invasive and highly used method for the study of rodent cerebral blood flow (CBF). Flow-sensitive alternating inversion recovery (FAIR) is one of the most commonly used MR-sequences for this purpose and exists with many different strategies to record the images. This study investigates Look-Locker (LL) TrueFISP readout for FAIR as an alternative to the
Spaces for multilingual education : language orientations in the national curricula of Sweden and Finland
Both Sweden and Finland have education systems promoting equity and equality. However, recent societal and political changes linked to increased immigration have created new challenges in efforts to support linguistic diversity. This paper aims to explore how multilingualism is represented in the national compulsory school curricula in the two contexts, using the language orientation framework: la
Factor structure of the Friends and Family interview
The aim of this study was to specify the latent construct structure of the Friends and Family Interview (FFI: Steele & Steele, 2005) based on its dimensional scale coding protocol. The FFI is a semi-structured interview measuring attachment in middle childhood. We analyzed data from 341 FFI interviews with children aged 7–12 years, recruited in the Scandinavian Öresund Region. Exploratory Fact
Assessment of flow pattern and temperature profiles by residence time distribution in typical structured packed beds
The flow and temperature fields in packed beds are rather complex but are of great importance since they will influence macroscopic parameters and the overall performance of the packed bed system. Regions with either too high or too low velocity are not preferred since they will decrease the heat and mass transfer characteristics of packed beds. The residence time distribution (RTD) is a way to as
Somatostatin secretion by Na+-dependent Ca2+-induced Ca2+ release in pancreatic delta cells
Pancreatic islets are complex micro-organs consisting of at least three different cell types: glucagon-secreting alpha, insulin-producing beta and somatostatin-releasing delta cells. Somatostatin is a powerful paracrine inhibitor of insulin and glucagon secretion. In diabetes, increased somatostatinergic signalling leads to defective counter-regulatory glucagon secretion. This increases the risk o

The generalisability of randomised clinical trials : an interim external validity analysis of the ongoing SENOMAC trial in sentinel lymph node-positive breast cancer
Purpose: None of the key randomised trials on the omission of axillary lymph node dissection (ALND) in sentinel lymph-positive breast cancer have reported external validity, even though results indicate selection bias. Our aim was to assess the external validity of the ongoing randomised SENOMAC trial by comparing characteristics of Swedish SENOMAC trial participants with non-included eligible pat
Second malignancies in multiple myeloma; emerging patterns and future directions
The changing landscape of treatment options for multiple myeloma has led to a higher proportion of patients achieving deep, long-lasting responses to therapy. With the associated improvement in overall survival, the development of subsequent second malignancies has become of increased significance. The risk of second malignancy after multiple myeloma is affected by a combination of patient-, disea

Numerical investigation of particle deposition in film-cooled blade leading edge
This study numerically investigates film-cooling performance and particle trajectories in AGTB (two rows of cylindrical holes equipped on suction side (SS) and pressure side (PS) of the leading edge, respectively) turbine cascade. Particle deposition on a turbine blade is analyzed by calculations of capture efficiency and impact efficiency. The turbulent flow is modeled by the Realizable k-ε turbu
Cross-section analyses of attitudes towards science and nature from the International Social Survey Programme 1993, 2000, and 2010 surveys
This paper explores public attitudes towards science and nature in twelve countries using data from the International Social Survey Programme environment modules of 1993, 2000, and 2010. Analysis of attitude items indicates technocentric and pessimistic dimensions broadly related to the Dominant Social Paradigm and New Environmental Paradigm. A bi-axial dimension scale is utilized to classify resp
