This paper presents results from time-optimal path tracking for industrial robots. More specifically, three subproblems are studied and experimentally evaluated. The first is a contact-force control approach for determining the geometric robot motion, such that the tool centre point of the robot is moved according to the specification. The second problem is off-line solution of the optimisation pr

This paper presents a mutual coupling based calibration method for time-division-duplex massive MIMO systems, which enables downlink precoding based on uplink channel estimates. The entire calibration procedure is carried out solely at the base station (BS) side by sounding all BS antenna pairs. An Expectation-Maximization (EM) algorithm is derived, which processes the measured channels in order t

Theoretical approaches to learning in practice-based jazz improvisation contexts include situated learning and ecological perspectives. This article focuses on how interest-driven, self-sustaining jazz learning activities can be matched against the concepts of stolen knowledge (Brown & Duguid, 1996) and landscape of learning (Bjerstedt, 2014). Based on an extensive interview study with Swedish

For monotone systems evolving on the positive orthant, two types of Lyapunov functions are considered: Sum- and max-separable Lyapunov functions. One can be written as a sum, the other as a maximum of functions of scalar arguments. Several constructive existence results for both types are given. Notably, one construction provides a max-separable Lyapunov function that is defined at least on an arb

A search for squarks and gluinos in final states containing high-pT jets, missing transverse momentum and no electrons or muons is presented. The data were recorded in 2012 by the ATLAS experiment in root s = 8 TeV proton-proton collisions at the Large Hadron Collider, with a total integrated luminosity of 20.3 fb(-1). Results are interpreted in a variety of simplified and specific supersymmetry-b

Popular Abstract in Swedish Den psykiatriska vården har genomgått radikala förändringar under de två senaste decennierna. Antalet platser inom den slutna vården har mer än halverats. Målsättningen från politikerna både på det nationella och internationella planet har varit att stänga mentalsjukhusen och erbjuda öppnare och humanare vårdformer samt öka utbudet av boendeformer för personer som drabbThis study investigated psychosocial environment, needs, quality of life and social network for persons with severe mental illness in supported housing in the community. Eighty-three persons with severe mental illness living in three different types of housing setting accepted to participate in the interviews, which took place between December 1997 and April 2000. These settings were: inpatient se

Using the concepts of social norms and social reality, this chapter explores why legal reforms that aimed to facilitate the formalization of informal workers have largely failed to influence vulnerable groups in developing countries. It explores the use of legal reforms in order to achieve development and poverty reduction. Using empirical material from a qualitative study conducted in Colombia am

Urbanisation has burdened cities with many problems associated with growth and the physical environment. Some of the urban locations in India are becoming increasingly vulnerable to natural hazards related to precipitation and flooding. Thus it becomes increasingly important to study the characteristics of these events and their physical explanation. This work studies rainfall trends in Delhi and

For triangles with linear vertex motion, common practice is to backface cull a triangle if it is backfacing at both the start and end of the motion. However, this is not conservative. We derive conservative tests that guarantee that a moving triangle is backfacing over an entire time interval and over the area of a lens. In addition, we present tests for the special cases of only motion blur and o

Time-resolved medical data has important applications in a large variety of medical applications. In this paper we study automatic analysis of dynamical renal scintigraphies. The traditional analysis pipeline for dynamical renal scintigraphies is to use manual or semiautomatic methods for segmentation of pixels into physical compartments, extract their corresponding time-activity curves and then c

The study explored the utility of four-point preprandial glucose self-monitoring to calculate several indices of glycemic control and variability in a study adding the DPP-4 inhibitor vildagliptin to ongoing insulin therapy. This analysis utilized data from a double-blind, randomized, placebo-controlled crossover study in 29 patients with type 2 diabetes treated with vildagliptin or placebo on top

In this paper ethical implications of parental participation in paediatric care are discussed. The paper is based on interviews with 20 parents, whose children were admitted and operated on at a paediatric surgery department in Sweden. In one part of the interview the parent was invited to speak about situations experienced as problematic during the hospitalization. Three different types of situat
