Hybrid knowledge bases (HKBs), proposed by Nerode and Subrahmanian, provide a uniform theoretical framework for dealing withthe mixed data types and multiple reasoning modes required for solving logical deployment problems. Algorithms based on mixed integer linear programming techniques have been developed for the syntactic subset of HKBs corresponding to function-free Prolog-like logic programs. In this study, we examine the ability of neural networks to solve a more comprehensive set of problems expressed within the hybrid knowledge base framework. the objective of this research is to design and implement a nonlinear optimization procedure for solving extended logic programs with neural networks. We focus upon two types of extensions which are typically required in the formulation of logical deployment problems. the first type of extension, which we shall refer to as a Type I extension, consists of embedding numerical and geometric constraints into logic programs. the second type of extension, which we shall call a Type II extension, consists of incorporating optimization problems into logic clauses.
We consider logicprogramming languages with a parametric type system, first described by Mycroft and O’Keefe, that allows generic polymorphism. It is well known that provided certain conditions hold typed definite l...

this volume contains a selection of papers presented at the 15thinternationalconference on Applications of Declarative programming and Knowledge M- agement, INAP 2004, and the 18th Workshop on logicprogramming, WLP 2004, which were held jointly in Potsdam, Germany, from March 4th to 6th, 2004. Declarative programming is an advanced paradigm for the modeling and solving of complex problems. this speci?cation method has become more and more attractive in recent years, for example, in the domains of databases, for the processing of natural language, for the modeling and processing of combinatorial problems, and for establishing knowledge-based systems for the Web. the INAP conferences provide a forum for intensive discussions of appli- tions of important technologies around logicprogramming, constraint problem solving, and closely related advanced software. they comprehensively cover the impact of programmable logic solvers in the Internet society, its underlying te- nologies, and leading-edge applications in industry, commerce, government, and social services. the Workshops on logicprogramming are the annual meeting of the Society for logicprogramming (GLP e.V.). they bring together researchers interested in logicprogramming, constraint programming, and related areas like databases and arti?cial intelligence. Previous workshops have been held in Germany, A- tria, and Switzerland. thetopicsoftheselectedpapersofthisyear’sjointconferenceconcentrateon three currently important ?elds: knowledge management and decision support, constraint programming and constraint solving, and declarative programming and Web-based systems.

A non-volatile memory transistor based on an air-stable p-type polymer semiconductor (PDVT-10) and organic ferroelectric polymer (PVDF-TrFE) is developed. the solution-processed memory transistor, which can operate well in air, has extremely stable storage properties with a 100 V memory window when the gate voltage sweeps in the range of +/- 80 V. the programming and erasing behavior of air-stable memory device are demonstrated. Although the retention behaviors and cyclic stability of the ferroelectric memory devices remain to be further improved and optimized, their capability
