THE INFLUENCE OF THE GEOMETRIC SHAPE ABOVE THE VULNERABILITY OF BUILDINGS - KULA TYPE FROM OLTENIA AND MUNTENIA REGIONS

open access: yesJournal of Industrial Design and Engineering Graphics, 2019
The main goal of this paper is to highlight the vulnerability during the life time of kula buildings from Oltenia and Muntenia Regions from Romania. This research highlights the characteristic features of massive kula type buildings by masonry built ...

A Normalizing Intuitionistic Set Theory with Inaccessible Sets [PDF]

open access: yesLogical Methods in Computer Science, 2007
We propose a set theory strong enough to interpret powerful type theories underlying proof assistants such as LEGO and also possibly Coq, which at the same time enables program extraction from its constructive proofs.

Study of the Boundary Value Problems for Nonlinear Wave Equations on Domains with a Complex Structure of the Boundary and Prehistory

open access: yesMathematics, 2021
We study a boundary value problem for nonlinear partial differential equations of the hyperbolic type on the plain in a domain with a complex boundary.

Classical Mathematics for a Constructive World

open access: yes, 2010
Interactive theorem provers based on dependent type theory have the flexibility to support both constructive and classical reasoning. Constructive reasoning is supported natively by dependent type theory and classical reasoning is typically supported by ...

Error-Correcting Codes for Automatic Control [PDF]

open access: yes, 2008
Systems with automatic feedback control may consist of several remote devices, connected only by unreliable communication channels. It is necessary in these conditions to have a method for accurate, real-time state estimation in the presence of channel ...

Towards a constructive simplicial model of Univalent Foundations

open access: yes, 2021
We provide a partial solution to the problem of defining a constructive version of Voevodsky's simplicial model of univalent foundations. For this, we prove constructive counterparts of the necessary results of simplicial homotopy theory, building on the

On some peculiar aspects of the constructive theory of point-free spaces

open access: yes, 2010
This paper presents several independence results concerning the topos-valid and the intuitionistic (generalized) predicative theories of locales. In particular, certain consequences of the consistency of a general form of Troelstra's uniformity principle

Virtual Evidence: A Constructive Semantics for Classical Logics [PDF]

open access: yes, 2014
This article presents a computational semantics for classical logic using constructive type theory. Such semantics seems impossible because classical logic allows the Law of Excluded Middle (LEM), not accepted in constructive logic since it does not have

STUDY ON VERTICAL AXIS WIND TURBINE PERFORMANCE BASED ON IMPROVED SAVONIUS ROTOR TYPE

open access: yesJournal of Industrial Design and Engineering Graphics, 2020
In the context of environmental policies aimed at gradual reduction of carbon emissions around the world today must be considered the methods of obtaining energy from renewable sources at hand.

Approximations of Sobolev norms in Carnot groups [PDF]

open access: yes, 2010
This paper deals with a notion of Sobolev space $W^{1,p}$ introduced by J.Bourgain, H.Brezis and P.Mironescu by means of a seminorm involving local averages of finite differences. This seminorm was subsequently used by A.Ponce to obtain a Poincar\'e-type
