Purpose: It has previously been shown that continuous intratracheal insufflation of oxygen (CIO) is superior to intermittent positive pressure ventilation (IPPV) regarding gas exchange and haemodynamics. The purpose of this study was to investigate gas exchanged and haemodynamics with a new technique of phase-controlled intermittent insufflation of oxygen (PIIO) compared to CIO. Method: Twenty (20
An iterative algorithm is adopted to construct approximate representations of matrices describing the scattering properties of arbitrary objects. The method is based on the implicit evaluation of scattering responses from iteratively generated excitations. The method does not require explicit knowledge of any system matrices (
Over the last century, many women have contributed to the field of control engineering. Nevertheless, women are generally in the minority. This article highlights the contribution of women since the inception of control engineering to highlight good exemples to coming generations. A repository of portraits of women in control engineering is currently being curated and made available through the un
Efficiently finding covariate model structures that minimize the need for random effects to describe pharmacological data is challenging. The standard approach focuses on identification of relevant covariates, and present methodology lacks tools for automatic identification of covariate model structures. Although neural networks could potentially be used to approximate covariate-parameter relation
In the mining industry, flotation is a commonly used process to separate valuable minerals from waste rock in a concentrator. The rougher flotation is the first stage of the process and in Boliden AB’s concentrator at Aitik, it consists of two lines of four flotation cells each. In this paper we consider one line and the buffer tank upstream of it. Modeling this process step, and maintaining an up
Mixed-effects models are used to describe the inter-patient variability in drugs. Modeling of these variabilities include both fixed and random effects. Fixed effects relate covariates such as age and weight to compartment volumes and clearances, whereas random effects account for unexplained variability. Traditionally, the development of fixed effects models is an inefficient process where covari
During planar motion, contact surfaces exhibit a coupling between tangential and rotational friction forces. This article proposes planar friction models grounded in the LuGre model and limit surface theory. First, distributed planar extended state models are proposed, and the elastoplastic model is extended for multidimensional friction. Subsequently, we derive a reduced planar friction model cou
Background: The absence of Epithelial Membrane Protein 3 (EMP3) on red blood cells (RBCs) underlies the MAM-negative (MAM−) phenotype. EMP3 is a ubiquitous protein found at low levels in most tissues but with higher expression in hematopoietic cells. Low levels of CD44 are a signature of MAM− RBCs due its proposed physical interaction with EMP3, indicating that EMP3 stabilises CD44 in the membrane
In this paper, a novel decentralized leader-follower control scheme for multi–agent systems is devised, where each agent communicates only with a subset of neighboring mates. The goal is to track assigned trajectories for the centroid and the formation of the system. The desired trajectories are known only by a subset of agents, named leaders: the other agents, the followers, are required to estim
Characteristic modes of arbitrary 2-D periodic systems are analyzed using scattering parameter data. This approach bypasses the need for periodic integral equations and allows for characteristic modes to be computed from generic simulation or measurement data. Example calculations demonstrate the efficacy of the method through comparison against a periodic method of moments (MoM) formulation for a
Cartesian impedance control is a type of motion control strategy for robots that improves safety in partially unknown environments by achieving a compliant behavior of the robot with respect to its external forces. This compliant robot behavior has the added benefit of allowing physical human guidance of the robot. In this paper, we propose a C++ implementation of compliance control valid for any
Gaze-control and gaze-assistance in software development tools have so far been explored in the setting of code editing, but other developer activities like code review could also benefit from this kind of tool support.In this paper, we present GANDER, a platform for user studies on gaze-assisted code review. As a proof of concept, we extend the platform with an assistant that highlights name rela
Beyond-5G wireless communication systems will feature advanced, key technologies such as large intelligent surfaces (LISs) composed of a very large number of antenna elements. The concomitant tremendous data rate requirements, due to the communication between these antennas, necessitate careful algorithm-architecture codesign. This paper presents an application-specific integrated circuit (ASIC) a
A visit of an art exhibition can lead to feelings of frustration, exclusion, and not-being welcomed.Above all exhibitions of contemporary and modern art can due to the often conceptuel and abstract caracter of the artworks experienced as exclusive.As many researches has shown a museum visit become meaningful to us if a relation to what is seen can generates.Not just the consumption of cultural sup
I Sverige kan den som blir häktad på grund av misstanke för brott bli ålagd restriktioner enligt 24 kap. 5a § RB, om åklagaren finner att det föreligger risk att den misstänkte kommer att försvåra utredningen genom att undandra bevisning, det vill säga om en kollusionsfara finns. Häktningsrestriktioner innebär att den häktade blir förbjuden att vistas tillsammans med andra intagna, mottaga besök, A person being arrested in Sweden on the suspicion of a crime may be subjected to restrictions according to chapter 24 § 5a RB while incarcerated, if the prosecutor finds there is a risk that the suspect will interfere with the investigation. The detainee being placed under restrictions during detention, may be forbidden to meet other detainees, receive visits from friends and family, receive phon
The European Model of Sports includes features that form part of the European identity, such as inclusion, tolerance and respect. It has been developed since the 1990s, and has been a cornerstone in the sports policy documents put forward by EU institutions, and was further strengthened by the introduction of Article 165 TFEU. The European Model of Sports is now under threat after the initiation o
