  1. 26. Population dynamics and demography - inferences from stochastic models

    Författare :Jonas Knape; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Time series analysis of population abundances is a common approach to making inferences about population dynamics, and especially for estimating density dependence. Traditionally the impact of potential errors in observations or measurements of the abundances on inference has been ignored. LÄS MER

  2. 27. On the Application of Short-term Causal Models

    Författare :Anders Baudin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Causal (econometric) models are often employed as instruments for for-casting in short-term planning within organizations. The aim of this work is to contribute to an understanding of the short-term aspects of causal model building. LÄS MER

  3. 28. Opinion Dynamic Models of Decision-Making in Traffic

    Författare :Carl-Johan Heiker; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; decision-making; Autonomous vehicles; continuous-time Markov chains; human road users; model predictive control; opinion dynamics;

    Sammanfattning : Autonomous vehicles (AVs) have the potential to improve both the efficiency and the safety of road traffic. Vehicles that can plan their routes, anticipate accidents and communicate open the door to transportation that is nearly free of human error. LÄS MER

  4. 29. From meteors to space safety : dynamical models and radar measurements of space objects

    Författare :Daniel Kastinen; Johan Kero; Asta Pellinen-Wannberg; Mats Holmström; Detlef Koschny; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Meteors; meteor shower; atmosphere; meteoroids; meteoroid stream; small-body dynamics; solar system; comets; asteroids; near-Earth objects; space safety; space debris; radar; MU; EISCAT;

    Sammanfattning : Every day the Earth's atmosphere is bombarded by 10-200 metric tons of dust-sized particles and larger pieces of material from space called meteoroids. Dust and meteoroids come from parent bodies such as comets and asteroids, which are remnants from the formation of the solar system. LÄS MER

  5. 30. An architecture for diagnostic reasoning based on causal models

    Författare :Jan Olsson; Stockholms universitet; []
    Nyckelord :Diagnostiska metoder; Dynamisk programmering; Expertsystem; Databehandling;

    Sammanfattning : This thesis proposes an architecture for diagnostic reasoning employing causal models. The architecture embodies a knowledge representation at the problem-solving layer. That is, the way a problem is solved—in this case to arrive at a diagnosis—is an integral part of the knowledge representation. LÄS MER
