Sensing and Generating New Opportunities for Value Innovation: How Team Behaviour Contributes to Success or to Failure?
2017
The behavioral side of the decision process inherent to strategy is an issue that is gaining attention from both academic and practitioners. At the same time, the Schumpeterian conception of innovation, returns to gain relevance in an environment where technology leads to process dematerialization and exponential paths of change. In this context, this paper analyses which decision processes, cognitive abilities and heuristics lead to sense and generate value innovation for customers. The analysis of 26 master student teams that ran the same strategy simulator show that the consideration and description of a wide range of alternatives and team agreement as a result of discussion of such alte…
An integrated and shared approach to sea of the regional town master plan of Sicily
2006
The work addresses one of the most important problems in contemporary environmental land planning. Already existing procedures, in fact, must now conform to the new requirements imposed by the recent national and international regulations and standards that call for a more conscious approach to the use of natural resources. Strategic Environmental Assessment (SEA), for example, takes into account, the different effects of a plan in various fields such as the environment, the economy and the development. This obviously calls for global analysis tools that could help administrators, stakeholders and technicians in the decision-making process of such complex systems. SEA of the Town Master Pla…
A knowledge-based master-model approach with application to rotating machinery design
2011
Novel rotating machinery design concepts and architectures are being explored to reduce mass, energy consumption, manufacturing costs, and environmental impact while increasing performance. As component manufacturers supply parts to original equipment manufacturers, it is desirable to design the components using a systems approach so that they are optimized for system-level performance. To accomplish that, suppliers must be able to model and predict the behavior of the whole machinery. Traditional computer-aided design/computer-aided engineering master-modeling approaches enable manual changes to be propagated to linked models. Novel knowledge-based master-modeling approaches enable automa…
An extension of the fractional model for construction of asphalt binder master curve
2015
Knowledge and prediction of viscoelastic behaviour of asphalt binder is of great interest in order to design asphalt mixtures for civil construction of road and airports with good performances. The capability of a fractional model – requiring a very limited number of parameters – to describe and predict the linear viscoelastic behaviour of asphalt binder subjected to sinusoidal oscillations is investigated. Experimental data of complex modulus, |G*|, and phase angle, δ, are used to validate the proposed constitutive model. Based on the proposed extension of a fractional model, complex modulus isotherms for a range of frequencies can be created simply starting from isochronals at frequency v…
On the validity of non-Markovian master equation approaches for the entanglement dynamics of two-qubit systems
2010
In the framework of the dissipative dynamics of coupled qubits interacting with independent reservoirs, a comparison between non-Markovian master equation techniques and an exact solution is presented here. We study various regimes in order to find the limits of validity of the Nakajima–Zwanzig and the time-convolutionless master equations in the description of the entanglement dynamics. A comparison between the performances of the concurrence and the negativity as entanglement measures for the system under study is also presented.
Restraining approach for the spurious kinematic modes in hybrid equilibrium element
2013
The present paper proposes a rigorous approach for the elimination of spurious kinematic modes in hybrid equilibrium elements, for three well known mesh patches. The approach is based on the identification of the dependent equations in the set of inter-element and boundary equilibrium equations of the sides involved in the spurious kinematic mode. Then the kinematic variables related to the dependent equations are reciprocally constrained and, by application of master slave elimination method, the set of inter-element equilibrium equations is reduced to full rank. The elastic solutions produced by means of the proposed approach verify the homogeneous, the inter-element and the boundary equi…
La planificación basada en competencias en los másteres oficiales: un reto para el profesorado universitario
2010
To focus the attention on competences means a radical change for the teaching design. It is one of the places where the most effective changes are expected. The research presented here tries to analyze the way that competences are used when describing official Master degrees. The competences of 87 Master degrees from 9 universities are analyzed. The results show that most Masters do not specify their competences. The most common ones refer to the knowledge application and that an enormous heterogeneity exists when classifying the types of competences. Desde la planificación docente, centrar la atención en las competencias supone un giro radical. Es uno de los elementos en los que se aspira …
Caffeate and piperidine-3-ol derivatives from the stem bark of Cassia sieberiana
2019
A new caffeate derivative from the ethanol extract of the stem bark of Cassia sieberiana DC. is described herein along with the known secondary metabolites spectaline (2), iso-6-cassine (3), 3-O-methyl-chiro-inositol (4), monobehenin (5), octyl nonadecyloate (6), β-sitosterol (7), stigmasterol (8) and sitosterol 3-O-β-D-glucopyranoside (9). The chemical structures were elucidated by means of various spectroscopic and spectrometric techniques. Extract and isolated compounds were devoid of inhibitory action against the herein selected bacterial strains (MICs > 256 μg/mL) but showed capacities to reduce 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical (EC50 < 3 μg/mL) considerably better than the …
Robust synchronization and fault detection of uncertain master-slave systems with mixed time-varying delays and nonlinear perturbations
2010
In this paper, the problem of robust synchronization and fault detection for a class of master-slave systems subjected to some nonlinear perturbations and mixed neutral and discrete time-varying delays is investigated based on an H ∞ performance condition. By introducing a descriptor technique, using Lyapunov-Krasovskii functional and a suitable change of variables, new required sufficient conditions are established in terms of delay-dependent linear matrix inequalities to synthesize the residual generation scheme. The explicit expression of the synchronization law is derived for the fault such that both asymptotic stability and a prescribed level of disturbance attenuation are satisfied fo…
