GenSAT is a family of local hill-climbing procedures for solving propositional satisfiability problems. We restate it as a navigational search process performed on an N-dimensional cube by a fictitious agent with limited lookahead. Several members of the GenSAT family have been introduced whose efficiency varies from the best in average for randomly generated problems to a complete failure on t...

Magnetoreception can play a substantial role in long distance navigation by animals. I hypothesize that locomotion guided by a magnetic compass sense could also play a role in short distance navigation. Animals identify mates, prey, or other short distance navigational goals using different sensory modalities (olfaction, vision, audition, etc.) to detect sensory cues associated with those goals...

This paper proposes using a Component Approach to model navigation in a hypertext application. It proposes Navigational Semantic Units (NSUs), which are component-oriented units that describe some meaning of navigation from the user’s perspective. The NSUs are an abstraction of a navigational model and are the basis for a methodology to design hypermedia applications based on the Model View Con...

: Lung cancer is one of the most common causes death in US. Screening for lung has therefore become imperative as early detection shown to improve survival. Low dose computed tomography (CT) imaging chest an important tool help identify nodules screened population. Once a nodule identified, there are several ways obtain diagnosis, with technique dependent on location and size nodule. About 500,...

Autonomous navigation is an essential component of an indoor mobile robot for elderly care. For an interactive user experience the robot should be able to understand multiple navigational tasks and perform them as optimally as possible. User may issue multiple random destinations to the robot to reach in a scenario like finding the elderly person, but to navigate randomly may result in an ineff...

Homing pigeons are known for their excellent homing ability, and their brains seem to be functionally adapted to homing. It is known that pigeons with navigational experience show a larger hippocampus and also a more lateralised brain than pigeons without navigational experience. So we hypothesized that experience may have an influence also on orientation ability. We examined two groups of pige...

This paper presents P-OQL (Pcte-Object-QueryLanguage) a domain-oriented query language for Pcte. Pcte is the ECMA standard for a public tool interface (PTI) for system development environments (SDE) and includes as one of its major components a structurally object-oriented object management system (OMS). Whereas the ECMA standard is only concerned with navigational access to the object base, ex...

This paper will describe new work that attempts to perform the modelling of human behaviour not at the level of visible patterns of motion, but at the level of intentions. By inferring intentions in terms of known goals, it becomes possible to explain the behaviour of people moving around within the field of view of a video camera (e.g. ”Agent 25 went to exit 8 via sub-goals 34 and 21”). Earlie...
