The entrepreneurial process: The link between intentions and behavior
2020
Abstract Entrepreneurship has been widely studied in recent decades, and it has been linked to other research areas such as social psychology. Remarkable contributions have combined these fields to explore how to predict entrepreneurial intentions. Building on previous research on the factors that predict students' intentions to start a business, this study explores the link between intentions and behavior. The aim is to ascertain whether university students have genuine intentions to start a business and see themselves as capable of doing so. This study draws upon Ajzen’s theory of planned behavior to examine the role of students' and/or prospective entrepreneurs' skills and capabilities. …
Experimental Study Regarding of Bending Behaviour of Stabilizator Link
2016
Abstract This paper presents an experimental study of the behavior of anti-roll power link subjected to bending, power link coming from an Opel Astra G. The power link is made of PA66 GF30 polyamide. For this study, there were used a universal testing machine (Instron 5587) and a real-time strain measurement optical system (Aramis). The results showed are those obtained in the case of a compression force of 1,000 [N] namely: major Strain ε1, minor strain ε2, equivalent von Mises strain, displacement on X axis, displacement on Y axis (compression force direction), displacement on Z axis.

Topological characterization of virtual braids
2015
The purpose of this thesis is to give a topological characterization of virtual braids. Virtual braids are equivalence classes of planar braid-like diagrams identified up to isotopy, Reidemeister and virtual Reidemeister moves. The set of virtual braids admits a group structure and is called the virtual braid group. In Chapter 1 we present a general introduction to the theory of virtual knots, and we discuss some properties of virtual braids and their relations with classical braids. In Chapter 2 we introduce braid-Gauss dia- grams, and we prove that they are a good combinatorial reinterpretation of virtual braids. In particular this generalizes some results known in virtual knot theory. As…
Standard and Z2-Regge theory in two dimensions
1998
Abstract We qualitatively compare two versions of quantum Regge calculus by means of Monte Carlo simulations. In Standard Regge Calculus the quadratic link lengths of the triangulation vary continuously, whereas in the Z2-Regge Model they are restricted to two possible values. The goal is to determine whether the computationally more easily accessible Z2 model retains the characteristics of standard Regge theory.
Variations on S-fold CFTs
2019
A local SL(2,Z) transformation on the Type IIB brane configuration gives rise to an interesting class of superconformal field theories, known as the S-fold CFTs. Previously it has been proposed that the corresponding quiver theory has a link involving the T(U(N)) theory. In this paper, we generalise the preceding result by studying quivers that contain a T(G) link, where G is self-dual under S-duality. In particular, the cases of G = SO(2N), USp'(2N) and G_2 are examined in detail. We propose the theories that arise from an appropriate insertion of an S-fold into a brane system, in the presence of an orientifold threeplane or an orientifold fiveplane. By analysing the moduli spaces, we test…

Scattering on Riemannian Symmetric Spaces and Huygens Principle
2018
International audience; The famous paper by L. D. Faddeev and B. S. Pavlov (1972) on automorphic wave equation explored a highly romantic link between Scattering Theory (in the sense of Lax and Phillips) and Riemann hypothesis. An attempt to generalize this approach to general semisimple Lie groups leads to an interesting evolution system with multidimensional time explored by the author in 1976. In the present paper, we compare this system with a simpler one defined for zero curvature symmetric spaces and show that the Huygens principle for this system in the curved space holds if and only if it holds in the zero curvature limit.
About the link between the detailed description of transitions in an ion and the average-ion models
2009
We study the link which exists between microscopic (detailed) models for the evolution of the electronic configurations in a population of ions and the macroscopic (average ion) models. Rigorous asymptotics are presented in situations where they exist (large temperature; almost empty or almost full shells), and numerical simulations are presented.
Authority and Coordination
1995
There are many possible starting points for attempts to link authority with the coordination of human interactions: the most famous forerunner here is of course David Hume with his theory of justice. I will, however, start from a more recent classic. Herbert A. Simon’s Administrative Behaviour (1945, 2nd ed. 1957) includes an important theory for the role of authority. It is an obvious sign of the lack of communication between different branches and traditions in social theory that many jurists and political theorists emphasizing the coordinative functions of authority have paid no attention to Simon’s classical book.
