Sjögren's syndrome: epidemiological risk factors and biomarkers

Primary Sjögren’s syndrome (pSS) is an autoimmune disease, primarliy affecting women, characterised by inflammation and destruction of exocrine glands with a prevalence of 0.01-0.09%. About one-third of the patients also suffer from extraglandular manifestations e.g. inflammation in the lungs, kidneys, skin or nerves. Apart from dyness symptoms, patients often suffer from fatigue and pain. Little

Patient-Reported Outcomes but not Demographic Factors Predict Normal Muscle Function 2-5 Years After ACL Injury: A Cross-Sectional Study

Integrating mission and task planning in an industrial robotics framework

This paper presents a framework developed for an industrial robotics system that utilises two different planning components. At a high level, a multi-robot mission planner interfaces with a fleet and environment manager and uses multiagent planning techniques to build mission assignments to be distributed to a robot fleet. On each robot, a task planner automatically converts the robot's world mode

Relevant scenarios for home monitoring solutions for older adults

In this chapter, we describe three common scenarios of older people’s living situation in order to increase the understanding of when and how home monitoring can be used among older people at risk of worsening health. We aim at describing the different circumstances under which monitoring approaches and personal care solutions can be applied. Then, we describe relevant geriatric conditions and thr

Reviews and taxonomies

This chapter summarizes the existing review articles in the field of monitoring and diagnosing older adults at risk of health deterioration, in the context of smart-homes. We provide taxonomy of these notable review articles, characterizing their aims and reviewing approaches of proposed monitoring systems capable of detecting health threats in smart-home settings. We included reviews, which focus

Datasets

Publicly available datasets constitute the ground to evaluate and compare the performance of proposed approaches for monitoring older patients at home. In this chapter, we shed light on the importance of using datasets as a benchmarking tool for comparing various monitoring techniques for detecting the health threats, which we discussed in the previous chapters. The methods, which are tested by us

Monitoring technology

This chapter aims at giving an insight into a variety of available monitoring technologies and techniques, which aim to provide solutions to the issues listed in Chap. 3. First, we start with discussing possible data collection approaches, by revealing choices of available sensors and underlying constrains. Second, we provide a summary of sensors used for data acquisition in regard to needed medic

Tracking in object action space

In this paper we focus on the joint problem of tracking humans and recognizing human action in scenarios such as a kitchen scenario or a scenario where a robot cooperates with a human, e.g., for a manufacturing task. In these scenarios, the human directly interacts with objects physically by using/manipulating them or by, e.g., pointing at them such as in "Give me that...", 10 recognize these type

Fast and accurate unknown object segmentation for robotic systems

Object segmentation is the first step towards more advanced robotic behaviors, as robots need to localize objects before attempting tasks such as grasping or manipulation. A robot vision system should be able to provide accurate object hypotheses in reasonably high frame rates, using images and possibly also depth data. This work proposes a fixation-based object segmentation algorithm able to cope

Evaluation of human body tracking system for gesture-based programming of industrial robots

Is low-cost tracking precise enough for recognition of pointing actions? We investigate the quality of the human body tracking available with a Kinect camera by comparing it to a state-of-the-art motion capture system. The application is action recognition with parametric hidden Markov Models (PHMMs) for programming industrial robots. The data from the Kinect is overall more noisy and potentially

Imitation learning of non-linear point-to-point robot motions using dirichlet processes

In this paper we discuss the use of the infinite Gaussian mixture model and Dirichlet processes for learning robot movements from demonstrations. Starting point of this work is an earlier paper where the authors learn a non-linear dynamic robot movement model from a small number of observations. The model in that work is learned using a classical finite Gaussian mixture model (FGMM) where the Gaus

Improvement in tuberculosis infection control practice via technical support in two regions of Ethiopia.

Background Globally recommended measures for comprehensive tuberculosis (TB) infection control (IC) are inadequately practiced in most health care facilities in Ethiopia. The aim of this study was to assess the extent of implementation of TB IC measures before and after introducing a comprehensive technical support package in two regions of Ethiopia. Methods We used a quasi-experimental design, wh

Using human gestures and generic skills to instruct a mobile robot arm in a feeder filling scenario

Mobile robots that have the ability to cooperate with humans are able to provide new possibilities to manufacturing industries. In this paper, we discuss our mobile robot arm that can a) provide assistance at different locations in a factory and b) be programmed using complex human actions such as pointing in Take this object. We discuss the use of the mobile robot for a feeding scenario where a h

3D scanning of object surfaces using structured light and a single camera image

We present a novel low-cost device for scanning object surfaces based on structured LED (Light Emitting Diode) light and a single, monocular image from a standard machine vision camera. During the calibration phase we find the displacement of the imaged LED-projected marker points as a function of depth. Using this displacement data and a suitable interpolation technique, the depth of surface poin

Motor Imagery to Facilitate Sensorimotor Re-Learning (MOTIFS: More Learning) After Anterior Cruciate Ligament Injury: A Randomized Controlled Trial Protocol

Introduction: Treatment after Anterior Cruciate Ligament (ACL) injury includes physical therapist supervised neuromuscular training, with or without surgical reconstruction, aiming to improve patient-reported outcomes and muscle function. Despite this treatment, sensorimotor deficiencies persist, possibly constituting a contributing factor for risk of re-injury, early-onset osteoarthritis, and a l

Primitive-based action representation and recognition

In robotics, there has been a growing interest in expressing actions as a combination of meaningful subparts commonly called motion primitives. Primitives are analogous to words in a language. Similar to words put together according to the rules of language in a sentence, primitives arranged with certain rules make an action. In this paper we investigate modeling and recognition of arm manipulatio

Iris recognition by fusing different representations of multi-scale Taylor expansion

The random distribution of features in an iris image texture allows to perform iris-based personal authentication with high confidence. We propose three new iris representations that are based on a multi-scale Taylor expansion of the iris texture. The first one is a phase-based representation that is based on binarized first and second order multi-scale Taylor coefficient. The second one is based

Unsupervised learning of action primitives

Action representation is a key issue in imitation learning for humanoids. With the recent finding of mirror neurons there has been a growing interest in expressing actions as a combination meaningful subparts called primitives. Primitives could be thought of as an alphabet for the human actions. In this paper we observe that human actions and objects can be seen as being intertwined: we can interp

Unsupervised action classification using space-time link analysis

We address the problem of unsupervised discovery of action classes in video data. Different from all existing methods thus far proposed for this task, we present a space-time link analysis approach which consistently matches or exceeds the performance of traditional unsupervised action categorization methods in various datasets. Our method is inspired by the recent success of link analysis techniq
