3D structural modeling and restoration of the Apennine-Maghrebian chain in Sicily: Application for non-cylindrical fold-and-thrust belts

2019

International audience; Thirteen seismic reflection profiles and field observations have been used to build a three-dimensional watertight geological model of the sub-surface architecture of the Trapanese carbonate platform unit of the Apennine-Maghrebian chain in the Mt. Kumeta and Mt. Rocca Busambra (NW Sicily, Italy). Either a single step or a two-step thrust-fault deformation model is acceptable on the basis of seismic interpretation but the integration of 3D model reconstruction and 3D geomechanical restoration, validates only the scenario with a single stage of deformation.The 3D model highlights along strike variations of the structural style for the Trapanese unit where pre-existing…

A SOA-based health service platform in smart home environment

2011

The increasing demand for a good healthcare quality has brought Information and Communication Technology to an important role in healthcare domain. The trend in decreasing number of formal healthcare workers gives further pressure to move non-urgent treatments to the patients' homes. However, delivering healthcare services to meet the changing needs of inhabitants in a smart home requires an open and flexible service creation and integration environment so that the modification of existing services as well as creation of new services can be achieved in a timely manner. This paper presents a vision of a logical integration platform in a smart home environment, integrating various devices and…

Building a medical research cloud in the EASI-CLOUDS project

2015

Summary The demand for Information Technology (IT) resources is constantly growing in the scientific area. The ability to store and process increasing amounts of data has transformed many research disciplines like the life sciences, which now rely on complex data processing and data analytics. Cloud computing can provide researchers with scalable and easy-to-use hardware and software resources and allows on-demand access to services, tools, or even complete work environments. The European research project EASI-CLOUDS has developed a service delivery platform with special regard to service integration, monitoring and management, and the negotiation of service level agreements. In order to de…

A framework for IoT service experiment platforms in smart-city environments

2016

Cities provide an excellent platform for gathering and detection of massive amount of data from cities and citizens. Emergence of new digital technologies inspires not only city governments but also city residents, researchers, companies and other stakeholders in discovering and creating new innovative solutions to solve urban challenges and improve peoples´ everyday life. Developing novel Internet of Things (IoT) solutions for cities and citizens requires facilities where IoT applications and services can be tested and experimented. The challenge for many smart-city test and experimentation platforms (TEPs), like living labs, has been the lack of sustainable value creation model. This has …

Cloud Based Business Processes Orchestration

2014

Abstract As the value concept of the cloud is evolving from a cost-saving mechanism into a growth instrument, more and more organizations are turning to the cloud in an attempt to redesign their core business processes. The opportunity for process innovation is vast, and it will take the disciplined approach of BPM, with the computing understanding and accessibility of the cloud, to make the most of what lies ahead. With the popularity of cloud computing, Platform-as-a Service (PaaS) becomes one of the core technical enablers of enterprises to change the delivery of services to both customers and internal organizations. An application in an enterprise needs to take into account various spec…

Exploring New Service Portfolio Management

2017

Most research on the management of innovation portfolios has focused on new product portfolios, whereas the management of new service portfolios has not been researched correspondingly. This paper addresses this literature gap by exploring portfolio management of New Service Development (NSD) activities empirically. The paper applies a qualitative research design, where data was collected in 52 in-depth interviews with managers and employees involved with NSD. The study finds that the portfolio management activities and processes were carried out in parallel with the NSD process, and that the most important stakeholders in the NSD portfolio management organization were top managers not inv…

Correlation based hierarchical clustering in financial time series

2005

We review a correlation based clustering procedure applied to a portfolio of assets synchronously traded in a financial market. The portfolio considered consists of the set of 500 highly capitalized stocks traded at the New York Stock Exchange during the time period 1987-1998. We show that meaningful economic information can be extracted from correlation matrices.

An investigation of the self- and inter-incompatibility of the olive cultivars 'Arbequina' and 'Koroneiki' in the Mediterranean climate of Sicily

2016

In this investigation, the self-(in)compatibility of the Spanish cultivar Arbequina and the Greek cultivar Koroneiki was studied for the first time in Sicily, where these low vigour cultivars were recently introduced in super-intensive olive groves. Self- (S.P.) and openpollination (O.P.) tests, observation of fruit set and paternity test of seeds with microsatellite (SSR) markers, were performed to ascertain whether these cultivars were self-fertile and/or inter-compatible. For S.P. tests, branches with flowers at the balloon stage were bagged. For the O.P. tests, flowers were left to pollinate under natural conditions. Fruits from S.P. and O.P. were collected in November and fruit set was…

A System to Simplify the Use of Mounted Shakers for Harvesting Olives and Dry Fruits

2009

The shakers for harvesting olives and dry fruits have reached a high standard and their use is increasing rapidly. In order to satisfy the different demand, manufacturers offer a wide range of shakers, from the more expensive self-propelled ones to those to be mounted on the tractor’s power lift, with shaking headers of different mass and size, suitable for the different orchard characteristics. Self-propelled shakers have high steering capacity and optimum visual field for the operator, so their working capacity is very high with respect to that of mounted shakers, which are less expensive but have lower steering capacity and a limited view on the header. Therefore the approaching of mount…
