چکیده

The axiomatization of arithmetical properties in theorem proving creates many straightforward inference steps. In analyzing mathematical proofs with the CERES (Cut-Elimination by Resolution) system, it is convenient to hide these inferences. The central topic of the thesis is the extension of the CERES method to allow reasoning modulo equational theories. For this, the inference systems of Sequent Calculus modulo and Extended Narrowing and Resolution replace their non-equational counterparts in CERES. The method is illustrated by examples comparing inference modulo the theory of associativity and commutativity with unit element to inference in the empty theory.

Optimal Control via Integrating the Dynamics of Magnetorheological Dampers and Structures

Magnetorheological (MR) dampers have the advantage of being tuned by low voltages. This has attracted many researchers to develop semi-active control of structures in theory and practice. Most of the control strategies first obtain the desired forces of dampers without taking their dynamics into consideration and then determine the input voltages according to those forces. As a result, these st...

Integrating Fuzzy Inference System, Image Processing and Quality Control to Detect Defects and Classify Quality Level of Copper Rods

Human-based quality control reduces the accuracy of this process. Also, the speed of decision making in some industries is very important. For removing these limitations in human-based quality control, in this paper, the design of an expert system for automatic and intelligent quality control is investigated. In fact, using an intelligent system, the accuracy in quality control is increased. It...

Deduction modulo theory

Contemporary proof theory goes into several directions at the same time. One of them aims at analysing proofs, propositions, connectives, etc., that is at decomposing these objects into more atomic ones. This often leads to design systems that are weaker than Predicate logic, but that have better algebraic or computational properties, and to try to reconstruct part of Predicate logic on top of ...
