Thom Fr\"uhwirth presented a short, elegant and efficient Prolog program for the n queens problem. However may be seen as rather tricky one not convinced about its correctness. This paper explains in declarative way, provides proofs of correctness completeness. The specification are declarative, i.e. they abstract from any operational semantics. is approximate, it unnecessary to describe progra...

INTRODUCTION In neuroscience and psychology it has become common to distinguish between declarative and non-declarative forms of learning (e.g., Squire and Zola, 1996). The perspective (Squire, 2004, p. 173) that declarative learning “refers to the capacity for conscious recollection about facts and events and is the kind of memory that is impaired in amnesia and dependent on structures in the ...

SAFE is an example of declarative trust management. Principals use a declarative language to make statements about one another and about objects in the system. These statements are secure assertions: they are authenticated and the source (speaker) of every statement is tracked. Principals reason from these statements according to policy rules, which are also written in the declarative language....

Abstract The topic of multiple forms of memory is considered from a biological point of view. Fact-and-event (declarative, explicit) memory is contrasted with a collection of non conscious (non-declarative, implicit) memory abilities including skills and habits, priming, and simple conditioning. Recent evidence is reviewed indicating that declarative and non declarative forms of memory have dif...

Declarative debugging has been proposed as a suitable technique for developing debuggers in the context of declarative languages. However, to become really useful debuggers must be able to deal with those parts of the languages that have no clear declarative semantics but are widely used in realistic programs. We explain in this paper how a declarative debugger of wrong answers for the lazy fun...

Retroactive interference from a declarative memory can prevent the consolidation of motor skill memories over wakefulness, but not over a night of sleep. Recently, motor imagery (MI) learning has been showed to allow for a stronger resistance against procedural interference rather than physical practice, but whether declarative interference might impact sleep-dependent consolidation process of ...

Benchmarking Declarative Approximate Selection Predicates Oktie Hassanzadeh Master of Science Graduate Department of Computer Science University of Toronto 2007 Declarative data quality has been an active research topic. The fundamental principle behind a declarative approach to data quality is the use of declarative statements to realize data quality primitives on top of any relational data so...

Healthy sleep is essential in children's cognitive, behavioral, and emotional development. However, remarkably little is known about the influence of sleep disorders on different memory processes in childhood. Such data could give us a deeper insight into the effect of sleep on the developing brain and memory functions and how the relationship between sleep and memory changes from childhood to ...

The meaning of a declarative sentence and that of an interrogative sentence differ in their aspect of mood. A semantics of mood has to account for the differences in meaning between these sentences, and it also has to explain that sentences in different moods may have a common core. The meaning of the declarative mood is to be explained not in terms of actual force (contra Dummett), but in term...
