  1. 1. Cognitive strategies in simple addition and subtraction : Process models based on analyses of response latencies and retrospective verbal reports

    Författare :Maj-Lene Hedenborg; Stellan Ohlsson; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; cognition; mental arithmetic; addition; subtraction; process models; response latencies; verbal reports; errors; psykologi; Psychology;

    Sammanfattning : The purpose of this thesis is to explore cognitive processes used by children and adults when solving simple arithmetic problems, and to develop process models for describing these processes. The studies in the thesis were based mainly on analyses of response latencies and retrospective verbal reports, separately and in combination. LÄS MER

  2. 2. Reducing Long Tail Latencies in Geo-Distributed Systems

    Författare :Kirill Bogdanov; Dejan Kostic; Gerald Q. Maguire Jr.; Marc Shapiro; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud Computing; Geo-Distributed Systems; Replica Selection Algorithms; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Computing services are highly integrated into modern society. Millions of people rely on these services daily for communication, coordination, trading, and accessing to information. To meet high demands, many popular services are implemented and deployed as geo-distributed applications on top of third party virtualized cloud providers. LÄS MER

  3. 3. Towards Climate Based Early Warning and Response Systems for Malaria

    Författare :Maquins Odhiambo Sewe; Joacim Rocklöv; Clas Ahlm; Yesim Tozan; Madeleine Thomson; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Malaria; Mosquito; Lead time; Early Warnings; Forecasts; Economic Evaluation; Rainfall; KEMRI CDC HDSS; Kenya; Temperature; LST; NDVI; Climate; HDSS; GAM; GAMBOOST; DLNM; Remote Sensing; Net Benefit; Cost-Effectiveness; Boosting Regression; Weather; Public Health; Infectious Diseases; folkhälsa; Public health; Epidemiology; epidemiologi;

    Sammanfattning : Background: Great strides have been made in combating malaria, however, the indicators in sub Saharan Africa still do not show promise for elimination in the near future as malaria infections still result in high morbidity and mortality among children. The abundance of the malaria-transmitting mosquito vectors in these regions are driven by climate suitability. LÄS MER

  4. 4. Investigations of neural attractor dynamics in human visual awareness

    Författare :David N. Silverstein; Pawel Herman; Martin Ingvar; Karl Friston; KTH; []

    Sammanfattning : What we see, how we see it and what emotions may arise from stimuli has long been studied by philosophers, psychologists, medical doctors and neuroscientists. This thesis work investigates a particular view on the possible dynamics, utilizing computational models of spiking neural attractor networks. LÄS MER

  5. 5. Effects of iron supplementation on iron status, health and neurological development in marginally low birth weight infants

    Författare :Staffan Berglund; Magnus Domellöf; Olle Hernell; Michael K Georgieff; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Auditory brainstem response; behavior; breast feeding; cognition; erythropoietin; ferritin; growth; hemoglobin; hepcidin; human infant; iron; iron deficiency; iron deficiency anemia; iron status; iron supplementation; low birth weight; morbidity; neurodevelopment; nutritional requirements; randomized controlled trial; Pediatrics; pediatrik;

    Sammanfattning : Background Due to small iron stores and rapid growth during the first months of life, infants with low birth weight (LBW) are at risk of iron deficiency (ID). ID in infancy is associated with irreversible impaired neurodevelopment. LÄS MER
