Development of an Extended Product Lifecycle Management through Service Oriented Architecture.
Organised by: Cranfield UniversityThe aim of this work is to define new business opportunities through the concept of Extended Product
Lifecycle Management (ExtPLM), analysing its potential implementation within a Service Oriented
Architecture. ExtPLM merges the concepts of Extended Product, Avatar and PLM. It aims at allowing a
closer interaction between enterprises and their customers, who are integrated in all phases of the life cycle,
creating new technical functionalities and services, improving both the practical (e.g. improving usage,
improving safety, allowing predictive maintenance) and the emotional side (e.g. extreme customization) of
the product.Mori Seiki – The Machine Tool Company; BAE Systems; S4T – Support Service Solutions: Strategy and Transitio
Three-Dimensional Solutions of Supersymmetrical Intertwining Relations and Pairs of Isospectral Hamiltonians
The general solution of SUSY intertwining relations for three-dimensional
Schr\"odinger operators is built using the class of second order supercharges
with nondegenerate constant metric. This solution includes several models with
arbitrary parameters. We are interested only in quantum systems which are not
amenable to separation of variables, i.e. can not be reduced to lower
dimensional problems. All constructed Hamiltonians are partially integrable -
each of them commutes with a symmetry operator of fourth order in momenta. The
same models can be considered also for complex values of parameters leading to
a class of non-Hermitian isospectral Hamiltonians.Comment: 14 page
La riabilitazione termale nel 150° Anniversario dell'Unità d'Italia. Un testimonial d'eccezione: Giuseppe Garibaldi.
Nell’anno in cui si celebra il 150° Anniversario dell’Unità d’Italia, il riemergere di alcune lettere di Giuseppe Garibaldi - che fanno riferimento ad un periodo di cure termali effettuato presso le Terme della Ficoncella e di Traiano (vicino Civitavecchia, Roma) - ci ha dato lo spunto per questo lavoro che intende considerare i numerosi trattamenti effettuati presso diverse stazioni termali italiane dall’Eroe dei Due Mondi per una patologia reumatica (probabilmente una poliartrite reumatoide) e per gli esiti di varie ferite di guerra, in particolare la ben nota ferita da arma da fuoco subita a livello dell’arto inferiore destro nel corso della battaglia d’Aspromonte, nel 1862
Water waves overtopping over barriers
A numerical and experimental analysis of the wave overtopping over emerged and submerged structures, is presented. An original model is used in order to simulate three-dimensional free surface flows. The model is based on the numerical solution of the motion equations expressed in an integral form in time-dependent curvilinear coordinates. A non-intrusive and continuous-in-space image analysis technique, which is able to properly identify the free surface even in very shallow waters or breaking waves, is adopted for the experimental tests. Numerical and experimental results are compared, for several wave and water depth conditions
New Two-Dimensional Quantum Models with Shape Invariance
Two-dimensional quantum models which obey the property of shape invariance
are built in the framework of polynomial two-dimensional SUSY Quantum
Mechanics. They are obtained using the expressions for known one-dimensional
shape invariant potentials. The constructed Hamiltonians are integrable with
symmetry operators of fourth order in momenta, and they are not amenable to the
conventional separation of variables.Comment: 16 p.p., a few new references adde
