An account of recent research of the groups of Costa Pessoa and Maurya is presented, focusing on the preparation of several polystyrene anchored complexes and their use as catalysts in functionalization of alkenes. The procedures for covalently binding the ligands or ligand precursors are outlined, as well as for coordination of the metal ions. Instrumental techniques used for the characterizat...
متن کاملMiguel Cruz Costa Calejo A Framework
This thesis describes a new approach to declarative debugging (error diagnosis) of logic programs. The main contributions are: • “Declarative source debugging”, a new approach requiring less queries from the user. • Improved algorithms for classical “declarative execution debugging”. • Support for Prolog impurities, such as cuts and side-effects. • The use of suspect trees, allowing uniform tre...
متن کاملIterative Bayes João
Naive Bayes is a well-known and studied algorithm both in statistics and machine learning. Bayesian learning algorithms represent each concept with a single probabilistic summary. In this paper we present an iterative approach to naive Bayes. The Iterative Bayes begins with the distribution tables built by the naive Bayes. Those tables are iteratively updated in order to improve the probability...
متن کاملStatement João Dias December , 2009
Despite years of work on retargetable compilers, creating a good, reliable back end for an optimizing compiler still entails a lot of hard work. Moreover, a critical component of the back end—the instruction selector—must be written by a person who is expert in both the compiler’s intermediate code and the target machine’s instruction set. By generating the instruction selector from declarative...
متن کاملUC Santa Cruz UC
The conditions and properties of hydrothermal vents and hydrothermal fields are compared in terms of their ability to support processes related to the origin of life. The two sites can be considered as alternative hypotheses, and from this comparison we propose a series of experimental tests to distinguish between them, focusing on those that involve concentration of solutes, self-assembly of m...
