Book chapter (peer-reviewed)abstract
- This chapter presents a telehealth system called GiraffPlus supporting independent living of elderly in their own home. GiraffPlus system is a complex system which monitors activities and physiological parameters in the home using a network of sensors. The elaborated information is presented to the primary user, the elderly, and to secondary users like health care and home care providers and possibly to family members as a help to assess possible health and wellbeing deterioration, provide acute alarms, and support health procedure. The secondary users can also visit the elderly via the Giraff, a teleoperated robot that can communicate and move in the home under the control of the secondary user. The chapter focusses in particular on the deployment of the system in six real homes in Sweden, Italy and Spain. The chapter outlines the technological various components used, the expectations of the users and the evaluation method.

In: 2013 6TH INTERNATIONAL CONFERENCE ON HUMAN SYSTEM INTERACTIONS (HSI). - New York : IEEE. - 9781467356374 - 9781467356350 ; , s. 578-585

Conference paper (peer-reviewed)abstract
- Early detection and adaptive support to changing individual needs related to ageing is an important challenge in today’s society. In this paper we present a system called GiraffPlus that aims at addressing such a challenge and is developed in an on-going European project. The system consists of a network of home sensors that can be automatically configured to collect data for a range of monitoring services; a semi-autonomous telepresence robot; a sophisticated context recognition system that can give high-level and long term interpretations of the collected data and respond to certain events; and personalized services delivered through adaptive user interfaces for primary users. The system performs a range of services including data collection and analysis of long term trends in behaviors and physiological parameters (e.g. relating to sleep or daily activity); warnings, alarms and reminders; and social interaction through the telepresence robot. The latter is based on the Giraff telepresence robot, which is already in place in a number of homes. Particular emphasis is put on user evaluation outside the laboratories. A distinctive aspect of the project is that the GiraffPlus system will be installed and evaluated in at least 15 homes of elderly people. The concept of “useworthiness” is central in order to assure that the GiraffPlus system provides services that are easy to use and worth using. In addition, by using existing and affordable components we strive to achieve a system that is affordable and close to commercialization.

Gray Balance Control in Sheet-Fed Offset Printing
- 2008

In: Proceedings of the Technical Association of the Graphic Arts, TAGA. - San Francisco. ; , s. -176, s. 153-176

Conference paper (peer-reviewed)abstract
- Newspaper printing can be controlled by visual gray balance assessment, a procedure which is widespread among newspaper printers in Sweden. In sheet-fed offset today, there is no fast and efficient way to process control the sheet-fed offset-press during production without using advanced online-systems. The control patches which are used in sheet-fed offset during the production often lack the possibility to assess gray balance, these usually work to determine full-tone ink densities and dot gain. The first objective of this study has been to evaluate the subjective quality experience (and objectively measurable factors) of print, where the quality control has been carried out based on gray balance control in sheet-fed offset. The second objective was to implement gray balance as a practical tool for the printers for a fast visual quality control in a sheet-fed offset printing. The study has shown that: 1) The gray balance can be used as a control parameter for control of quality in sheet fed offset. 2) A faster start-up and a more reliable print quality (fewer variations during production) can be achieved. The printer and the customer have access to a tool which facilitates communication, generates fewer misunderstandings, leads to less product returns and less production losses. With this tool it is easier for the printer to visually detect deviations without time consuming physical measurements. Also troubleshooting is easier; printers know instantly where the deviation is and can attend to it immediately.

Multiplex and quantifiable detection of nucleic acid from pathogenic fungi using padlock probes, generic real time PCR and specific suspension array readout
- 2009

In: Journal of Microbiological Methods. - : Elsevier BV. - 0167-7012 .- 1872-8359. ; 78:2, s. 195-202

Journal article (peer-reviewed)abstract
- A new concept for multiplex detection and quantification of microbes is here demonstrated on a range of infectious fungal species. Padlock probe methodology in conjunction with qPCR and Luminex technology was used for simultaneous detection of ten fungal species in one single experiment. By combining the multiplexing properties of padlock probes and Luminex detection with the well established quantitative characteristics of qPCR, quantitative microbe detection was done in 10-plex mode. A padlock probe is an oligonucleotide that via a ligation reaction forms circular DNA when hybridizing to specific target DNA. The region of the padlock probe that does not participate in target DNA hybridization contains generic primer sequences for amplification and a tag sequence for Luminex detection. This was the fundament for well performing multiplexing. Circularized padlock probes were initially amplified by rolling circle amplification (RCA), followed by a SybrGreen real time PCR which allowed an additive quantitative assessment of target DNA in the sample. Detection and quantification of amplified padlock probes were then done on color coded Luminex microspheres carrying anti-tag sequences. A novel technique, using labeled oligonucleotides to prevent reannealing of amplimers by covering the flanks of the address sequence, improved the signal to noise ratio in the detection step considerably. The method correctly detected fungi in a variety of clinical samples and offered quantitative information on fungal nucleic acid.

Sensor Network Infrastructure for a Home Care Monitoring System
- 2014
-
In: Sensors. - Basel : MDPI AG. - 1424-8220. ; 14:3, s. 3833-3860
-
Journal article (peer-reviewed)abstract
- This paper presents the sensor network infrastructure for a home care system that allows long-term monitoring of physiological data and everyday activities. The aim of the proposed system is to allow the elderly to live longer in their home without compromising safety and ensuring the detection of health problems. The system offers the possibility of a virtual visit via a teleoperated robot. During the visit, physiological data and activities occurring during a period of time can be discussed. These data are collected from physiological sensors (e.g., temperature, blood pressure, glucose) and environmental sensors (e.g., motion, bed/chair occupancy, electrical usage). The system can also give alarms if sudden problems occur, like a fall, and warnings based on more long-term trends, such as the deterioration of health being detected. It has been implemented and tested in a test environment and has been deployed in six real homes for a year-long evaluation. The key contribution of the paper is the presentation of an implemented system for ambient assisted living (AAL) tested in a real environment, combining the acquisition of sensor data, a flexible and adaptable middleware compliant with the OSGistandard and a context recognition application. The system has been developed in a European project called GiraffPlus.

A constraint-based approach for proactive, context-aware human support
- 2012
-
In: Journal of Ambient Intelligence and Smart Environments. - 1876-1364 .- 1876-1372. ; 4:4, s. 347-367
-
Journal article (peer-reviewed)abstract
- In this article we address the problem of realizing a service-providing reasoning infrastructure for pro-active humanassistance in intelligent environments. We propose SAM, an architecture which leverages temporal knowledge represented asrelations in Allen’s interval algebra and constraint-based temporal planning techniques. SAM provides two key capabilities forcontextualized service provision: human activity recognition and planning for controlling pervasive actuation devices. Whiledrawing inspiration from several state-of-the-art approaches, SAM provides a unique feature which has thus far not been addressedin the literature, namely the seamless integration of these two key capabilities. It does so by leveraging a constraint-basedreasoning paradigm whereby both requirements for recognition and for planning/execution are represented as constraints andreasoned upon continuously.
