Two Dimensional Prefix Codes of Pictures
A two-dimensional code is defined as a set X ⊆ Σ∗∗ such that any picture over Σ is tilable in at most one way with pictures in X . The codicity problem is undecidable. The subclass of prefix codes is introduced and it is proved that it is decidable whether a finite set of pictures is a prefix code. Further a polynomial time decoding algorithm for finite prefix codes is given. Maximality and com...
متن کاملA Greek Bronze Vase
When we think of Greek vases we generally have in mind Greek pottery, which has survived in quantity. Clay, one of the most perishable of materials, becomes one of the most indestructible in the firing. In fact, much of our knowledge of ancient civilizations is derived from the potsherds that are found in successive layers on ancient sites; a pot, once fired, may break into a hundred pieces, bu...
متن کاملStudy on Some Chemical Compounds on the Vase Life of Two Cultivars of Cut Roses
Rose (Rosa hybrida L.) is one of the mostly cultivated cut flowers in Iran and around the world. The study was carried out to increase the vase life and quality of cut rose ‘Grand Prix` and ‘Avallanche` by using various floral preservative solutions. Floral preservative solutions were AgNO3, 8-HQS, nano silver and distilled water. Treatments were compared with tap water as control. The experime...
متن کاملThe VAS Formalism in VASE
This paper discusses the visual algebraic speciication (vas) formalism and its supporting interactive environment (vase). The vas formalism is intended for the deenition of visual syntax and semantics and is aimed at generating language speciic environments. The collection construct of vas is emphasized in that it supports the convenient speciication of language constructs involving arbitrarily...
متن کاملsynthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
