Capsizing of use and can usually be recovered by the crew. Some types of dinghy are occasionally deliberately capsized, as capsizing and righting the vessel again can be the fastest means of draining water from the boat. Capsizing (but not necessarily turtling) is an inherent part of dinghy sailing. It is not a question of "if" but a question of "when". For those who do not want the experience, a keelboat monohull has physics on its side. But even yachts can capsize and turtle in extraordinary conditions, so design considerations are important. Such events can overcome skill and experience; boats need
Referring expression generation this question depends on how well descriptions can be expressed or found. A lot of the potential of KR frameworks has been left unused so far. Some of the different approaches are the usage of: Dale and Reiter (1995) think about referring expressions as distinguishing descriptions. They define: Each entity in the domain can be characterised as a set of attribute-value pairs for example formula_1type, dogformula_2, formula_1gender, femaleformula_2 or formula_1age, 10 yearsformula_2. The problem then is defined as follows: Let formula_7 be the intended referent, and formula_8 be the contrast set. Then, a set formula_9 of attribute–value pairs will represent
