The lining system, used in tunnel boring machines, is made of precast concrete segments. use steel fibers this kind support system can not only decrease production time and costs but also improve compressive, tensile as well flexural behaviors. A study has been carried out to examine the mechanical properties segments Tabriz metro line-2 project using three types fibers: 3D, 4D, 5D. Various exp...

Specification and verification in continuous problem domains are key topics for the practical application of formal methods and mechanized reasoning. I discuss one approach to linear continuous control systems and consider the challenges and opportunities raised for mechanized reasoning. These include practical implementation and integration issues, algorithms in computational real algebraic ge...

This paper examines the political economy of coordination in a simple two-sector model in which individuals’ choice of agricultural technology affects industrialization. We show that multiple equilibria exist such that the economy is either characterized by the use of a traditional agricultural technology and low industrialization or the use of a mechanized technology and high industrialization...

This article presents the analysis of the effect of two different types of work organization (the traditional and a new mechanized, more segmented one) in the packing sector of a luminary manufacturing company in Curitiba, Brazil. A macroergonomic analysis was conducted to evaluate the workers satisfaction with the job; the possible associated postural risk, the level of body pain/discomfort an...

ion-Based Information Technology: A Framework for Open Mechanized Reasoning.

From 1946 to 1953 ten conferences—the first nine held at the Beekman Hotel at 575 Park Avenue in New York, the last at the Nassau Inn in Princeton, New Jersey—brought together at regular intervals some of the greatest minds of the twentieth century. Sponsored by the Josiah Macy, Jr. Foundation, these meetings have since come to be known as the Macy Conferences. The mathematicians, logicians, en...

In my view, the “verification problem” is the theorem proving problem, restricted to a computational logic. My approach is: adopt a functional programming language, build a general purpose formal reasoning engine around it, integrate it into a program and proof development environment, and apply it to model and verify a wide variety of computing artifacts, usually modeled operationally within t...
