This paper evaluates the various approaches to strength and stiffness analysis of fracture osteosynthesis using a headless Herbert screw. The problem has been extensively addressed several scientific approaches, namely analytical approach, stochastic experimental (marginally) finite elements method. is illustrated on use prototype screw Ti: 4.0/1.4 × 30/7 (manufacturer: Medin, Czech Republic) s...

One of the global environmental problems facing man is pollution oceans by industrial and household garbage. Several hundred seals sea lions injured foreign objects are registered annually in reproductive rookeries. Without timely release, these animals doomed to perish. In this regard, purpose work was test technique freeing marine mammals from anthropogenic origin using methods remote sedatio...

This paper investigated the nature of mental representation of categorical knowledge by examining the neural substrates that support classification and feature inferences. The results from one experiment suggest that frontal lobe regions were activated when an inference task was given, while temporal lobe regions, especially the fusiform gyrus, became active when a classification task was given...

The computational modeling literature suggests that Exemplar models of categorization often replicated psychological phenomena better than Prototype models. However, those prototype models may have failed because the models’ important information processing mechanisms were misspecified. Here we introduce a new prototype model with complex yet realistic learning and selective attention processes...

Items that violate a category rule are remembered better than items that follow the rule. This finding cannot be predicted by exemplar models when all exemplars share the same attention along a dimension. With dimension-wide attention, violating and rule-following items are treated equally. When each exemplar selects which dimensions to attend to, exemplar models can predict the memory advantag...

feeding behavior of yellowfin seabream larvae during the first two weeks of larval life was studied by feeding larvae  on different ratios of live food and  microencapsulated diet (med). food consumption rate increased progressively with increasing larval weight. the results from visual observation of the larval guts under a light microscope indicated that yellowfin seabream larvae were able to...

This article presents a theory of categorization that accounts for the effects of causal knowledge that interrelates or links the features of categories. According to causal-model theory, people explicitly represent the probabilistic causal mechanisms that link category features, and classify objects by evaluating whether they were likely to have been generated by those mechanisms. Participants...

A fundamental aspect of human intelligence is the ability to represent and reason relations. Examples of relational thinking include our ability to appreciate analogies between diVerent objects or events (Gentner, 1983; Holyoak & Thagard, 1995); our ability to apply abstract rules in novel situations (e.g., Smith, Langston, & Nisbett, 1992); our ability to understand and learn language (e.g., K...

A unified quantitative approach to modeling subjects' identification and categorization of multidimensional perceptual stimuli is proposed and tested. Two subjects identified and categorized the same set of perceptually confusable stimuli varying on separable dimensions. The identification data were modeled using Shepard's (1957) multidimensional scaling-choice framework. This framework was the...
