  1. 6. Simplifying complex models : Application of modeling tools in exposure assessment of organic pollutants

    Författare :Emma Undeman; Michael McLachlan; Kathrin Fenner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mass balance model; environmental modeling; exposure modeling; bioaccumulation; organic contaminants; emission estimate; plant model; steady state; poly parameter linear free energy relationship; PPLFER; ecosystem susceptibility; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Thousands of chemicals are used in society, but the exposure to humans and other organisms has been measured only for a small number of compounds. Modeling tools constitute low-cost and effective alternatives to measurements for the assessment of exposure. LÄS MER

    Sammanfattning : In the ever-evolving landscape of wireless communication, the deployment of millimeter-wave (mmWave) technology has emerged as a game-changer for indoor environments. As the demand for high-speed, low-latency connectivity continues to surge, especially in densely populated areas, mmWave access point deployment has gained prominence due to its ability to deliver unprecedented data rates thanks to the available wide bandwidths.

  4. 8. Making sense of spatial, sensor and temporal information for context modeling

    Författare :Jose Antonio Monteagudo; Ramón David Jiménez; Dr. Marcelo Milrad; Mathias Hedenborg; Växjö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mobile devices; temporal information; context; content; ubiquitous computing; sensor data; mobile web server; Information processing; Informationsbehandling; Computer science; Datavetenskap;

    Sammanfattning : Context represents any information regarding the situation of entities, being these a person, place or object that is considered relevant to the interaction between a user and an application. The results obtained permits an user to save context information attached to a picture in a database, as well as retrieve pictures from that database and show it in a web interface with its context information associated.

  5. 9. Towards Intelligent Deformable Models for Medical Image Analysis

    Författare :Ghassan Hamarneh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape modeling; deformable models; principal component analysis; echocardiography; snakes; active shape models; deformable spatio-temporal shape models; medial-based shape profiles; statistical shape variation; spatio-temporal shape analysis; magnetic resonance imaging; hierarchical regional principal component analysis; oral lesions; dynamic programming; segmentation; spring-mass model; shape deformation; optical flow; medical image analysis; artificial life; physics-based modeling; deformable organisms; digital color images; medial axis; active contour models;

    Sammanfattning : Medical imaging continues to permeate the practice of medicine, but automated yet accurate segmentation and labeling of anatomical structures continues to be a major obstacle to computerized medical image analysis (MIA). Deformable models, with its profound roots in estimation theory, optimization, and physics-based dynamical systems, represent a powerful approach to the general problem of medical image segmentation.

  7. 10. Extending temporal action logic

    Författare :Joakim Gustafsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : An autonomous agent operating in a dynamical environment must be able to perform several "intelligent" tasks, such as learning about the environment, planning its actions and reasoning about the effects of the chosen actions. For this purpose, it is vital that the agent has a coherent, expressive, and well understood means of representing its knowledge about the world. LÄS MER
