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
Mental health problems among children and youth is positioned as one of the most urgent public health issues in Sweden today. Both research and official reports assert that mental health issues have increased among adolescents, especially girls, during the last decades. The aim of this study is to investigate how changes in childhood and gender discourses has implicated the construction of young p
The purpose of the present study was to examine the effect of blockade of N-methyl-D-aspartate (NMDA) receptors on the depolarization associated with severe hypoglycemia, which is commonly preceded by one or a few transient depolarizations reminiscent of cortical spreading depression (CSD). In the cerebral cortices of rats [K+](e) and [Ca2+](e) were measured with ion-selective microelectrodes. NMD
Purpose: The purpose of this paper is to enhance the heat transfer and thermal performance in the trailing edge region of the vane with vortex generators (VGs). Design/methodology/approach: This numerical study presents the enhancement of thermal performance in the trailing part of a gas turbine blade. In the trailing part, generally, pin fins are used either in staggered or in-line arrangements t
We have fabricated a silicon-glass two-phase droplet-based microfluidic system and implemented two-dimensional acoustic focusing prior to droplet generation as well as continuously throughout the whole system to increase particle detectability. Using acoustic focusing we have effectively minimized sedimentation of the encapsulated particles and thereby increased particle detectability by as much a
”The economy as instituted process” från 1957 torde vara den näst mest kända texten av Karl Polanyi (1886–1964) efter hans huvudarbete Den stora omdaningen från 1944. Här reder han ut skillnaden mellan ekonomibegreppets två innebörder av ekonomi som människors faktiska, substantiella utbyte med naturen och varandra och ekonomi som ett formaliserat tankesystem för rationell optimering. Polanyi argu
European Resuscitation Council (ERC) issued updated guidelines for postresuscitation care in 2015. This paper provides updated Swedish recommendations for neurological prognostication of patients remaining unconscious after cardiac arrest (CA). The prognostication should be based on independent methods; clinical and neurophysiological examinations, imaging and biomarkers. It should not be performe
Purpose: To describe congenital stationary night blindness (CSNB) with negative electroretinogram, hypoplastic discs, nystagmus and thinning of the inner nuclear layer (INL). Methods: Retinal structure was analyzed qualitatively with spectral domain optical coherence tomography and wide field imaging. Retinal function was evaluated with full-field electroretinography (ffERG). Molecular genetic tes
The report offers an analysis of the R&I system in Sweden for 2015, including relevant policies and funding, taking into account the priorities of the European Research Area and the Innovation Union. The report was prepared according to a set of guidelines for collecting and analysing a range of materials, including policy documents, statistics, evaluation reports, websites, etc. The quantitat
When Diffusion Tensor Imaging (DTI) is used in clinical studies, statistical hypothesis testing is the standard approach to establish significant differences between groups, such as patients and healthy controls. However, diffusion tensors contain six degrees of freedom, and the most commonly used univariate tests reduce them to a single scalar, such as Fractional Anisotropy. Multivariate tests th
Vid biblioteken i Burlöv och Ängelholm har tidigare bedrivits projekt att främja folkbibliotekens utveckling mot kulturhus (Kulturnämnden 2012). Arbetet med projekten, Kulturhusprojektet i Arlöv och Kulturstråket i Ängelholm, följdes i en studie av författaren och har rapporterats tidi-gare (Rivano Eckerdal 2013). Föreliggande rapport är resultatet av en uppföljande studie som be-dri¬vits under år
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
In 1798 the Royal Academy of Science instituted a classification of its members, designating the last class to be filled by those engaged with world of learning and beautiful arts. This study maps the population of this “erudite class” and analyzes the negotiation of epistemic virtues and merits linked to the nebulous field from which the class drew its members. The article argues that a previous
Many people use conspiracy theories to make sense of a changing world and its ever more complexif social structures (e.g., international financial systems, global bodies of governance), tragic events (e.g., terrorist attacks, man-made catastrophes, or natural disasters), or socio-political and economic issues (e.g., security, migration, distribution of resources, health care). The widespread flour
Since the late 1990s, researchers have been predicting that the era of neutrality in aid politics is coming to an end and that foreign organizations will have to take a more engaged stance. Yet while the boundaries between humanitarianism and development are fading, in some cases the neutrality norm is actually expanding rather than giving way to an engaged paradigm. Recognizing that the principle
