Homoclinic trajectories and chaotic behaviour in a piecewise linear oscillator
(2007)In this paper we consider the equation " x + x = sin(v root 2t) + s( x), where s( x) is a piece wise linear map given by min{5x, 1} if x = 0 and by max{ 1, 5x} if x < 0. The existence of chaotic behaviour in the Smale ... 
An eigenvalue problem for a quasilinear elliptic field equation on R^n
(2001)We study the field equation −Δu+V(x)u+εr(−Δpu+W′(u))=μu on Rn, with ε positive parameter. The function W is singular in a point and so the configurations are characterized by a topological invariant: the topological ... 
The knowledge bridging role of technical and scientific services in knowledgeintensive industries
(2008)Technical and Scientific Services (TSS) have been largely acknowledged by scholars and policy makers as means of knowledge transfer and diffusion within an innovation system. The paper argues that TSS play a critical ... 
Multiplicity of solutions of a zero mass nonlinear equation on a Riemannian manifold
(2008)The relation between the number of solutions of a nonlinear equation on a Riemannian manifold and the topology of the manifold itself is studied. The technique is based on LjusternikSchnirelmann category and Morse theory. ... 
Solitary waves solutions of a nonlinear Schroedinger equation
(Birkhaeuser, 2003)The aim of this note is to prove the existence of standing waves solutions of the following nonlinear Schrödinger equation I(∂ψ/∂t)=−Δψ+V(x)ψ+εN(ψ), where NM is a nonlinear differential operator. In [8] and [9] Benci and ... 
A Qlearning approach to derive optimal consumption and investment strategies
(2009)In this paper, we consider optimal consumption and strategic asset allocation decisions of an investor with a finite planning horizon. A Qlearning approach is used to maximize the expected utility of consumption. The first ... 
Aligning performance measurement systems with strategy: The case of environmental strategy
(2009)Alignment of an organization's performance measurement system with its strategy is widely advocated as a guiding principle in management control system design. Despite its importance, it is far from clear what strategic ... 
Environmental management control. An empirical study on the use of environmental performance measures in management control systems
(Ponsen & Looijen, 2005)Companies increasingly adapt their accounting systems to accommodate the internal demand of environmentalrelated information for making decisions and control their activities in compliance with extant environmental ... 
La nanoindustria: analisi dei principali player italiani nelle nanotecnologie
(Aracne Editrice, 2006)Il volume analizza il business delle nanotecnologie in Italia e fornisce un quadro dei principali player italiani attualmente operanti nella nanoindustria. È articolato in due parti; nella prima vengono fornite le nozioni ... 
An eigenvalue problem for a quasilinear elliptic field equation
(Elsevier, 2001)We study the field equation Deltau + V(x)u + epsilon (Delta (p)u + W'(u)) = mu mu on a bounded domain and on Rn, with E positive parameter. The function W is singular in a point and so the configurations are characterized ...
