SBIA, the Brazilian Symposium on Arti?cial Intelligence, is a biennial occasion meant to be the most discussion board of the AI neighborhood in Brazil. The SBIA 2004 used to be the seventeenth factor of the sequence initiated in 1984. for the reason that 1995 SBIA has been accepting papers written and provided merely in English, attracting researchers from worldwide. at the moment it additionally began to have a global software committee, keynote invited audio system, and court cases released within the Lecture Notes in Arti?cial Intelligence (LNAI) sequence of Springer (SBIA 1995, Vol. 991, SBIA 1996, Vol. 1159, SBIA 1998, Vol. 1515, SBIA 2000, Vol. 1952, SBIA 2002, Vol. 2507). SBIA 2004 used to be backed through the Brazilian computing device Society (SBC). It used to be held from September 29 to October 1 within the urban of S˜ ao Luis, within the northeast of Brazil, including the Brazilian Symposium on Neural Networks (SBRN). This a pattern of becoming a member of the AI and ANN groups to make the joint occasion a really fascinating one. particularly, in 2004 those occasions have been additionally held togetherwiththeIEEEInternationalWorkshoponMachineLearningandSignal Processing (MMLP), previously NNLP. The organizationalstructure of SBIA 2004was just like different overseas scienti?cconferences.Thebackboneofthe conferencewasthe technicalprogram whichwascomplementedbyinvitedtalks,workshops,etc.onthemainAItopics.

Optical Fiber Sensor Technology: Applications and Systems

Structures and functions in Optical Fiber Sensor know-how the basic expertise which underpins advancements in optical fiber sensors maintains to extend, and is still pushed to a truly huge quantity through advances in optoelectronics which were produced for the ever-expanding optical com­ munications structures and networks of the area.

Capillary Electrophoresis: Instrumentation and Operation

During this quantity the overall rules of capillary (zone) electrophoresis, the functionality of this separation approach to be anticipated, the instrumentation and methods to be had and useful directions for the operaton of CE tools might be mentioned. The emphasis should be at the regimen software of CE with commercially on hand tools, yet recognition may also be paid to devolpments nonetheless in a study level and their attainable implications for the longer term.

Investigations and Applications of Severe Plastic Deformation

Fabric processing innovations that hire serious plastic deformation have developed over the last decade, generating metals, alloys and composites having notable homes. editions of SPD equipment at the moment are in a position to growing monolithic fabrics with submicron and nanocrystalline grain sizes. The ensuing novel homes of those fabrics has resulted in a growing to be medical and advertisement curiosity in them.

3 The Family of Logics We present here the family of logics of Limited Bivalence, This is a parametric family that approximates classical logic, in which every approximation step can be decided in polynomial time. Unlike is parameterized by a set of formulas when contains all formulas of size at most can simulate an approximation step of The family can be applied to the full language of propositional logic, and not only to clausal form formulas, with an alphabet consisting of a countable set of propositional letters (atoms) and the connectives and and the usual definition of well-formed propositional formulas; the set of all well-formed formulas is denoted by The presentation of LB is made in terms of a model theoretic semantics.

In this formal framework the notion of Functional Dependency (FD) plays an outstanding role in the way in which the Relational Model stores, recovers and manages data. FDs were introduced in the early 70’s and, after an initial period in which several authors study in depth their power, they fell into oblivion, considering that the research concerning them had been completed. Recently, some works have proved that there is still a set of FDs problems which can be revisited in a successful way with novel techniques [2,3].
