Minimum Comparison Merging of Sets Of Approximately Equal Size
No full textThe problem of merging ordered sets in the least number of binary comparisons has been solved completely only for a few special cases. When the sets to be merged are of size m and ml (m:5m' ~~m+4) the tape merge algorithm has been shown to be optimum in the worst case. This paper significantly extends these results by showing that the tape merge algorithm is optimum in the worst case whenever one set is no larger than 1.5 times the size of the other. This result is obtained by defining an interesting and amusing two-player game isomorphic to the problem of merging ordered sets and analyzing the optimum strategies for each player. The form of this result should be applicable to the solution of similar sorting and selection problems.Technical report DCS-TR-7
Obtaining a grammar from a less formal language description
No full textIn this paper, we will try to show how CF-grammars can be constructed to describe sets of strings;* each string being of a type which is commonly found in programming languages. We will require that these grammars not only describe the syntax of such sets of strings, but also more importantly, reflect unambiguously in the derivation of these strings, the ordering or sequencing conventions commonly imposed on such strings. We will show how these grammars can be used to formally describe, at least in part, two aspects of programming language-operations operations. We will also be concerned with the case in which the grammars can be used to determine this ordering. The grammars we develop will be one of a number of possible grammars, each different in non-superficial ways, and each adequate to express the class of languages we will discuss.
A large part of the material presented here is tutorial. The material on constructing a grammar to satisfy a set of precedence relations constitutes the main contribution reported here.
We start by considering a non-CFG way of describing ordering conventions in an algebraic expression involving a number of appearances of a group of binary infix operations. This technique - precedence - has immediate appeal because of its familiarity as much, perhaps, because of its simplicity. After discussing precedence in some detail, we will show how some of the same effects can be-obtained with CFG's.
Precedence is a common device for describing the order in which operations are to be performed in expressions of the form: a + b * c ** b + c * e...Technical report DCS-TR-
Novos derivados xantônicos e quinolínicos: estudo de obtenção empregando, principalmente, metodologia heterogênea e investigação das propriedades biológicas
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências Físicas e Matemáticas, Programa de Pós-Graduação em Química, Florianópolis, 2011Neste trabalho foi sintetizada uma série de sistemas heterocíclicos da classe das xantonas e quinolinas empregando, principalmente, metodologia heterogênea (K-10, montmorrilonita). Foram obtidos os derivados xantônicos: 2-enamino xantonas e 2-imino xantonas. Os heterociclos quinolínicos da classe das 6-quinolinil chalconas e seus derivados N-óxido e sais N-metil foram eficientemente sintetizados. Esses compostos foram submetidos a reações de epoxidação e adição de Michael usando diferentes metodologias em meio heterogêneo e homogêneo (K-10, hidrotalcita). As epoxi chalconas foram obtidas com rendimentos excelentes e submetidas a estudos de aminólise frente ao dinucleófilo cloridrato de fenil hidrazina resultando em sistemas heterocíclicos polifuncionalizados da classe dos pirazóis. O emprego de metodologia heterogênea, suporte sólido montmorillonita, proporcionou condições brandas de reação, facilidade de isolamento e rendimentos significativos. Os compostos sintetizados foram submetidos a diferentes atividades biológicas in vitro e in vivo, tais como atividade inibidora da acetilcolinesterase, toxicidade frente à Artemia salina, atividade antimicrobiana, citotóxica e também avaliação do potencial hipoglicêmico.In this work was synthesized a series of heterocyclic systems of xanthones and quinolines class using mainly heterogeneous methodology (K-10, montmorillonite). The xanthone derivatives 2- enamine and 2-imino xanthones were obtained. The quinolinic heterocycles of the class 6-quinolinyl chalcones and their derivatives Noxide and N-methyl salts were efficiently synthesized. These compounds were subjected to epoxidation reactions and Michael addition using different methodologies in heterogeneous and homogeneous medium (K-10, hydrotalcite). The epoxy-chalcones were obtained with excellent yield and subjected to aminolysis studies with the dinucleophile phenylhydrazine hydrochloride, resulting in the polyfunctionalized heterocyclic systems of pyrazoles class. The use of heterogeneous methodology, solid support montmorillonite, provided mild reaction conditions, easy isolation and significant yields. The synthesized compounds were subjected to different biological activities in vitro and in vivo, such as acetylcholinesterase inhibitory activity, toxicity against the Arthemia saline, antimicrobial and cytotoxic activity and also evaluation of the hypoglycemic potential
