This thesis is proposing a research direction of using computation to help people fully take advantage of spatial cognition in thinking process. As our most important form of information processing spatial cognition provides thinking what logical and verbal means are inferior at. But without external aid, its application is tremendously constrained. Computation could play a role in circumventin...

In a large cyber-physical system, even if individual system elements interact with one another only locally, effects of local decisions quickly spread across the system and combine to yield global consequences. In order to reason about such a system without impractical amounts of communication and computation, we must summarize the system’s global state, and base individual decisions at least p...

Primary orthostatic tremor (POT) may be a cause of postural instability in older people. Though unusual, this condition is relatively easily diagnosed, based in part on typical clinical features, impacts on quality of life, and is amenable to symptomatic treatment (Heilman KM. Orthostatic tremor. Arch Neurol 1984; 41: 880-1). We present three cases seen in a general neurology clinic over a 15-m...

Why do we represent the world around us using causal generalizations, rather than, say, purely statistical generalizations? Do causal representations contain useful additional information, or are they merely more efficient for inferential purposes? This chapter considers the second kind of answer: it investigates some ways in which causal cognition might aid us not because of its expressive pow...

For those who have never taken the trouble to consider ways and methods of thinking and who wish to know of a readable and interesting introduction to the subject this small book of Canon Dewar's can be confidently recommended. Its three sections cover a great deal of ground. The first is concerned with different types of thinking and with the rules of the syllogism. The second calls attention ...

True. In low-income countries, openness to international trade is indispensable for rapid economic growth. Indeed, few developing nations have grown rapidly over time without simultaneous increases in both exports and imports, and virtually all developing countries that have grown rapidly have done so under open trade policies or declining trade protection. India and China are the best recent e...

Any patient with bilateral lymphadenopathy especially in Indian subcontinent is regarded as suffering from tuberculosis unless proved otherwise. This sometimes leads to unwarranted delay in correct diagnosis and management if there is ignorance regarding other rarer etiologies. Rosai-Dorfman Disease (RDD) may present in the same manner and should always be kept on the back of the mind to help a...

The introduction of Web-based resources to support learning and teaching in Higher education has prompted a plethora of research into their effectiveness. Of the studies that have examined the role of cognitive style and learning strategies, results have generally been rather inconclusive and contradictory. The purpose of this work was to investigate the relationship between a number of influen...

The BDI model for intelligent agents has been very influential for both theoretical and practical research in agent technology. It gave rise to a form of agent-oriented programming which could be called ’BDI programming’, the programming of the mental attitudes of agents, where these attitudes pertain to notions in the vein of beliefs, desires and intentions. In this talk I will sketch how we c...

An important activity in urban three-dimensional (3D) mobile navigation is browsing the buildings in the environment and matching them to those in the 3D city map. There are different factors affecting the recognition process such as changes in the appearances of buildings, weather, and illumination conditions. The current aim was to study the salience of different types of visual cues in the r...
