  • What is a healthy Nordic diet? Foods and nutrients in the NORDIET study
  • 2012
  • Ingår i: Food & Nutrition Research. - Bålsta : CoAction Publishing. - 1654-6628 .- 1654-661X. ; 56
  • Tidskriftsartikel (refereegranskat)abstract
    • <p><strong>BACKGROUND</strong>: A healthy Nordic diet (ND), a diet based on foods originating from the Nordic countries, improves blood lipid profile and insulin sensitivity and lowers blood pressure and body weight in hypercholesterolemic subjects.</p><p><strong>OBJECTIVE</strong>: To describe and compare food and nutrient composition of the ND in relation to the intake of a Swedish reference population (SRP) and the recommended intake (RI) and average requirement (AR), as described by the Nordic nutrition recommendations (NNR).</p><p><strong>DESIGN</strong>: The analyses were based on an estimate of actual food and nutrient intake of 44 men and women (mean age 53±8 years, BMI 26±3), representing an intervention arm receiving ND for 6 weeks.</p><p><strong>RESULTS</strong>: The main difference between ND and SRP was the higher intake of plant foods, fish, egg and vegetable fat and a lower intake of meat products, dairy products, sweets and desserts and alcoholic beverages during ND (p&lt;0.001 for all food groups). Intake of cereals and seeds was similar between ND and SRP (p&gt;0.3). The relative intake of protein, fat and carbohydrates during ND was in accordance with RI. Intake of all vitamins and minerals was above AR, whereas sodium intake was below RI.</p><p><strong>CONCLUSIONS</strong>: When compared with the food intake of an SRP, ND is primarily a plant-based diet. ND represents a balanced food intake that meets the current RI and AR of NNR 2004 and has a dietary pattern that is associated with decreased morbidity and mortality.</p><p>© 2012 Viola Adamsson et al.</p>

  • Pedatronics : Robotic toys as a source to evoke young girls’ technological interest
  • 2002
  • Ingår i: 32nd Annual Frontiers in Education. Leading a Revolution in Engineering and Computer Science Education : Conference Proceedings Volume III - Saturday Sessions. Boston Park Plaza Hotel, Boston, Massachusetts, November 6-9, 2002. - San Diego : Institute of Electrical and Electronics Engineers (IEEE). - 0-7803-7444-4 ; s. F1C-19-F1C-24
  • Konferensbidrag (refereegranskat)abstract
    • <p>This paper presents some results within Pedatronics; a fusion between pedagogics and mechatronics. Our research interest is to study what emerges in the play with robotic toys. Field-experimental studies of 67 year old children’s purposeless play with robotic toys created a self-developmental sphere, as well as evoked young girl’s technological interest. Both girls and boys prolonged and intensified their interest according to the amount of gadgets involved. The results disclose a learning potential, indicating the importance to develop strategies at an early stage in order to encourage girls to choose technological and engineering educations. The study recommend engineers and toy designers, in cooperation with children, to move towards ’Integrated Play Systems’. Due to an ethological method, the results differ from other studies of children’s play with technological advanced artefacts. © 2002 IEEE</p>

  • Egyptian women's attitudes and beliefs about female genital cutting and its association with childhood maltreatment
  • 2007
  • Ingår i: Nursing and Health Sciences. - Carlton, Vic, Australia : Blackwell Publishing. - 1441-0745 .- 1442-2018. ; 9:4, s. 270-276
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>This study aimed to establish Egyptian women's attitudes and beliefs about female genital cutting (FGC) or mutilation by applying a questionnaire module about violence to a subsample of 5249 married women from a total of 19 474 women who participated in the 2005 Egypt Demographic Health Survey. Women were interviewed to determine if they had been exposed to marital violence in the year prior to the survey, their attitudes and beliefs about FGC, and if they physically abused their children. The association of beliefs about FGC with maternal physical abuse was examined, adjusting for exposure to marital violence and other socio-demographic variables. Of the women surveyed 16.4% and 3.4% had been exposed to physical and sexual violence, respectively, during the year prior to the survey. Around 76% of the women surveyed intended to continue the FGC practice, and 69.8% had slapped or hit their children during the year prior to the survey. Holding positive beliefs about the practice of FGC or intending to continue it was associated with maternal physical abuse and this has significant implications for health and welfare workers in Egypt and for society in general.</p>

  • Modular interconnection system for optical PCB and backplane communication
  • 2002
  • Ingår i: Parallel and Distributed Processing Symposium., Proceedings International, IPDPS 2002, Abstracts and CD-ROM. - Los Alamitos, Calif. : IEEE Press. - 0-7695-1573-8 ; s. 245-250
  • Konferensbidrag (refereegranskat)abstract
    • <p>This paper presents a way of building modular systems with a powerful optical interconnection network. Each module, placed on a Printed Circuit Board (PCB), has a generic optical communication interface with a simple electronic router. Together with optical switching using micro-electromechanical system (MEMS) technology, packet switching over reconfigurable topologies is possible. The interconnection system gives the possibility to integrate electronics with optics without changing existing PCB technology. Great interest from industry is therefore expected and the cost advantages are several: reuse of module designs, module upgrades without changing the PCB, low-cost conventional PCB technology, etc. In the version described in this paper, the interconnection system has 48 bidirectional optical channels for intra-PCB communication on each board. For inter-PCB communication, a backplane with 192 bidirectional optical channels supports communication between twelve PCBs. With 2.5 Gbit/s per optical channel in each direction, the aggregated intra-PCB bit rate is 120 Gbit/s full duplex (on each PCB) while the aggregated inter-PCB bit rate is 480 Gbit/s full duplex. A case study shows the feasibility of the interconnection system in a parallel processing system for radar signal processing.</p>

  • Optoelectronic router with a reconfigurable shuffle network based on micro-optoelectromechanical systems
  • 2004
  • Ingår i: Journal of Optical Networking. - Washington, USA : Optical Society of America. - 1536-5379. ; 4:1, s. 1-10
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>An optoelectronic router with a shuffle exchange network is presented and enhanced by the addition of micro-optoelectromechanical systems (MOEMS) in the network to add the ability to reconfigure the shuffle network. The MOEMS described here are fully connected any-to-any crossbar switches. The added reconfigurability provides the opportunity to adapt the system to different common application characteristics. Two representative application models are described: The first has symmetric properties, and the second has asymmetric properties. The router system is simulated with the specified applications and an analysis of the results is carried out. By use of MOEMS in the optical network, and thus reconfigurability, greater than 50% increased throughput performance and decreased average packet delay are obtained for the given application. Network congestion is avoided throughout the system if reconfigurability is used.</p>

  • Reconfigurable Optical Interconnection Networks for High-Performance Embedded
  • 2005
  • Licentiatavhandling (övrigt vetenskapligt)abstract
    • <p>In embedded computer and communication system the capacity demand for interconnection networks is increasing continuously in order to achieve high-performance systems. Recent breakthroughs show that by using reconfigurability inside a single chip substantial performance gains can be added. However, in this thesis the focus is on system level reconfigurability (between chips or modules) and the performance gains that potentially can be achieved by having support for runtime reconfigurability on the system level.This thesis addresses the field of runtime system level reconfigurability with the use of optics in switches and routers for data- and telecommunications, and in multi-processor systems used for embedded signal processing. Several reconfigurable systems for switching and routing with support to adapt for asymmetric traffic patterns are proposed and compared to identify how design choices affect flexibility, performance etc. The proposed solutions are characterized by their multistage optical interconnection networks with reconfigurable shuffle patterns, where the reconfigurability is provided by micro-optical-electrical mechanical systems. More specifically, application-specific bottlenecks can be resolved by reconfiguring the interconnection network according to the current application demands. The benefits of the architectural solutions are confirmed by simulations that clearly show that the architectures can achieve high performance for both symmetric application characteristics and for several classes of asymmetric application characteristics. The final architectural solution is characterized by electronic packet-switches interconnected through an optical backplane, which is reconfigurable. Moreover, the thesis presents how several signal processing applications can be mapped to run concurrently in a time-shared scheme on a single reconfigurable multi-processor system that has high flexibility to adapt for the application currently at hand. The interconnection network is then adapted (reconfigured) according to the demands of the currently executed application in each time instance. The analysis shows that it is feasible to build such a system with today’s components.</p>

  • Reconfigurable optical interconnection system supporting concurrent application-specific parallel computing
  • 2005
  • Ingår i: 17th Symposium on Computer Architecture and High Performance Computing : SBAC-PAD 2005 : proceedings : 24-27 October, 2005, Rio de Janeiro, PR, Brazil. - Washington, DC, USA : IEEE Computer Society. - 0-7695-2446-X ; s. 44-51
  • Konferensbidrag (refereegranskat)abstract
    • <p>Application specific architectures are highly desirable in embedded parallel computing systems at the same time as designers strive for using one embedded parallel computing platform for several applications. If this can be achieved, the cost can be decreased in comparison to using several different embedded parallel computing systems. This paper presents a novel approach of running several high-performance applications concurrently on one single parallel computing system. By using a reconfigurable backplane interconnection system, the applications can be run efficiently with high network flexibility since the interconnect network can be adapted to fit the application that is being processed for the moment. More precisely, this paper investigates how the space time adaptive processing (STAP) radar algorithm and the stripmap synthetic aperture radar (SAR) algorithm can be mapped on a multi-cluster processing system with a reconfigurable optical interconnection system realized by a micro-optical-electrical mechanical system (MOEMS) crossbars. The paper describes the reconfigurable platform, the two algorithms and how they individually can be mapped on the targeted multiprocessor system. It is also described how these two applications can be mapped simultaneously on the optical reconfigurable platform. Implications and requirements on communication bandwidth and processor performance in different critical points of the two applications are presented. The results of the analysis show that an implementation is feasible with today's MOEMS technology, and that the two applications can be successfully run in a time-sharing scheme, both at the processing side and at the access for interconnection bandwidth.</p>

  • System-Level Runtime Reconfigurablity - Optical Interconnection Networks for Switching Applications
  • 2004
  • Ingår i: Proceedings of the International Conference on Engineering of Reconfigurable Systems and Algorithms, ERSA'04. - Athens, USA : CSREA Press. - 1-932415-42-4 - 978-193241542-1 ; s. 155-162
  • Konferensbidrag (refereegranskat)abstract
    • <p>The performance requirements on data and telecommunication switches and routers are continuously increasing and it is evident that new ideas and architectures must come to light to satisfy these new demands. In this paper, a runtime reconfigurable modular design approach is presented, using state-of-the-art microoptical-electrical mechanical system (MOEMS) components. The paper introduces a novel field of reconfigurability, where reconfiguration is made on the system level instead of, e.g. fine-granularity reconfigurable logic. Different reconfigurable system solutions with support to adapt for asymmetric traffic patterns are proposed and compared to see how design choices affect flexibility, performance etc. The proposed solutions are characterized by their multistage networks with reconfigurable shuffle patterns.</p>
