Looking at retrieval in field linguistics as a knowledge representation and reasoning problem, I explore in this paper the possibility of using a knowledge representation system known as Clasp to provide knowledge-based retrieval services in this domain.

We describe the conflict-driven answer set solver clasp, which is based on concepts from constraint processing (CSP) and satisfiability checking (SAT). We detail its system architecture and major features, and provide a systematic empirical evaluation of its features.

It is well known that the parallel order of microtubules in the plant cell cortex defines the direction of cell expansion, yet it remains unclear how microtubule orientation is controlled, especially on a cell-wide basis. Here we show through 4D imaging and computational modelling that plant cell polyhedral geometry provides spatial input that determines array orientation and heterogeneity. Mic...

BACKGROUND A wide range of foreign bodies has been retrieved from the gut and reported. The presentation may be in the form of complications like intestinal obstruction, perforation and formation of abscesses etc but there is no case report of a half open clasp knife being retrieved from the ileum, the patient having thrived, in spite of its presence for a period of eight months. CASE PRESENT...

Mission design and analysis present challenges in that almost all variables are in constant flux, yet the goal is to achieve an acceptable level of performance against a concept of operations, which might also be in flux. To increase responsiveness, our approach is to use automated planning tools that allow for the continual modification of spacecraft, ground system, staffing, and concept of op...

We describe the novel functionalities comprised in clasp’s series 3. This includes parallel solving of disjunctive logic programs, parallel optimization with orthogonal strategies, declarative support for specifying domain heuristics, a portfolio of prefabricated expert configurations, and an application programming interface for library integration. This is complemented by experiments evaluati...

Cortical surface reconstruction is important for functional brain mapping and morphometric analysis of the brain cortex. Several methods have been developed for the faithful reconstruction of surface models which represent the true cortical surface in both geometry and topology. However, there has been no explicit comparison study among those methods because each method has its own procedures, ...

The mechanical properties of the Akers type clasp, bar and frame made by the newly developed Ti-20Cr-0.2Si alloy were studied in order to obtain the indices for designing the cast partial denture base. In the case of the clasp, the bending strength of the Ti-20Cr-0.2Si alloy and pure Ti was lower than that of the Co-Cr alloy. The Ti-20Cr-0.2Si alloy and pure Ti may have the same retentive force...
