  2. 1. Reasoning with Bounded Cognitive Resources

    Author : Abdul Rahim Nizamani; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Artificial general intelligence; logical reasoning; inductive learning; proof systems; bounded cognitive resources; cognitive modeling;

    Abstract : Reasoning is an essential element of intelligence. Automated reasoning in formal and symbolic systems is a major topic in computer science and artificial intelligence (AI). Programs for computer-assisted and automated theorem proving are being constructed and used by mathematicians and logicians. READ MORE

  4. 2. Model-Based Cognitive Radio Strategies

    Author : Kasra Haghighi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spectrum utilization; cognitive radio; censorship; CLAPP; sequential detection;

    Abstract : Many frequency bands for wireless services are severely underutilized by the primary users (PU) to which these bands are assigned. This motivates a new class of wireless communication devices known as cognitive radios (CR), which identify vacant spectrum and transmit accordingly. READ MORE

  5. 3. In Search of Prototypes and Feminist Bank-Tellers: Exploring the Representativeness Heuristic

    Author : Håkan Nilsson; Peter Juslin; Karl Halvor Teigen; Uppsala universitet; []
    Keywords : Psychology; Cognitive psychology; Subjective probability; Representativeness heuristic; PROBEX; Category learning; Cognitive modeling; Conjunction fallacy; Psykologi;

    Abstract : According to the heuristics and biases approach, the representativeness heuristic (RH) is one of the heuristics available for assessing subjective probabilities (A. Tversky & D. Kahneman, 1974). A subjective probability assessed by the RH is determined by how representative the target object is of the target category. READ MORE

  6. 4. Intelligence and models for cognitive development

    Author : Linda Wänström; Daniel Thorburn; Gösta Hägglund; Dag Sörbom; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; intelligence; cognitive development; sample size; multilevel models; latent growth curve models; Statistics; Statistik; statistik; Statistics;

    Abstract : This dissertation focuses on cognitive development. In papers I and II, I study a special model, the second order latent growth curve model, that can be used to study cognitive development. Algebraic expressions for the variance of the estimation of slope differences are given. READ MORE

    Abstract : Irritable bowel syndrome (IBS) is a chronic visceral pain disorder with female predominance, characterized by recurrent abdominal pain and disturbed bowel habits in the absence of an identifiable organic cause. This prevalent and debilitating disease, which accounts for a substantial economic and individual burden, lacks exact diagnostic tools and effective treatment, since its pathophysiology remains uncertain.
