Proactive Future Internet: Smart Semantic Middleware for Overlay Architecture
2009
Some initiatives towards Future Internet, e.g., GENI, DARPA's Active Networks, argue the need for programmability of the network components. Some other initiatives extend this with argumentation for declarative networking, where the behavior of a network component is specified using some high-level declarative language, with a software-based engine implementing the behavior based on that specification. Our Proactive Future Internet (PROFI) vision follows these initiatives targeting also the following two problems: interoperability of the network elements programmed by different organizations, and the need for flexible cooperation among network elements, including coordination, conflict reso…
Influence of online shopping information dependency and innovativeness on internet shopping adoption
2008
PurposeThe paper's purpose is to analyse the influence of online shopping information dependency and innovativeness on the acceptance of internet shopping.Design/methodology/approachThe impact of online shopping information dependency, domain‐specific innovativeness and technology acceptance model (TAM) variables on future shopping intention has been tested through structural equation modelling techniques. The sample consisted of 465 Spanish consumers who had never purchased online.FindingsData analysis shows that consumer innovativeness and online shopping information dependency have a direct and positive influence on future online shopping intention and that the basic TAM hypotheses are f…
Key drivers of consumer loyalty to Facebook fan pages
2014
Purpose – With the rapid expansion of social networking sites, researchers and practitioners are challenged to understand drivers of customer loyalty in fan pages. The purpose of this paper is to identify the main drivers of Facebook fan page loyalty in order to promote the creation of affective links and long-term relationships with users. Design/methodology/approach – The impact of trust, fan page content dependency, attitude and consumer beliefs on loyalty to fan pages was tested through structural equation modelling techniques. The sample consisted of 691 Spanish Facebook users. Findings – Data analysis shows that attitude appears as a key variable in increasing loyalty to fan pages. T…

The role of information technology in relationships between travel agencies and their suppliers
2010
PurposeIn the context of relationship marketing, it is highly important for providers to identify the main buyer relational benefits influencing satisfaction and loyalty so that a continuous and satisfactory business relationship is guaranteed. Since it has been reported that information technology (IT) might constitute a source of satisfaction or dissatisfaction, this paper aims to test the moderating role of IT in the relationships between perceived benefits, satisfaction and loyalty in a business‐to‐business (B2B) setting.Design/methodology/approachA structural equations model was empirically tested. Additionally, the moderating role of IT in the relationships between perceived relationa…
The use of ICT in established and emerging tourist destinations: a comparative analysis in hotels
2013
Purpose – Information and communication technologies (ICT) may represent an important source of advantages for service companies. However, the literature suggests that ICT need to be adapted to the demands of the company and its customers. The purpose of this paper is to compare the ICT use in hotels situated in established (i.e. Spain) and emerging (i.e. Croatia) tourist destinations. Design/methodology/approach – Non-hierarchical cluster analysis is performed. Clusters are internally validated by a K-Means cluster analysis and a discriminant analysis. Analysis of variance is applied and contingency tables between cluster membership and hotel characteristics are created. Findings – The res…
A combined single range and single image device for low-cost measurement of building facade features
2008
The dimensions of building facades and window apertures are usually determined by making direct measurements using tapes and plummets. This approach, however, has a number of drawbacks including the physical risk to which the persons making the measurements are exposed. This paper proposes an indirect approach based on close range photogrammetry that is inexpensive, simple, fast and safe, and which does not require specialist staff or direct ground control measurements. The method is based on taking a picture using a digital camera and measuring the distance to the object using a handheld laser distance meter. Both items of equipment are mounted on a specially designed support that allows t…
Using a neural network for qualitative and quantitative predictions of weld integrity in solid bonding dominated processes
2014
Solid-state bonding occurs in several manufacturing processes, as Friction Stir Welding, Porthole Die Extrusion and Roll Bonding. Proper conditions of pressure, temperature, strain and strain rate are needed in order to get effective bonding in the final component. In the paper, a neural network is set up, trained and used to predict the bonding occurrence starting from the results of specific numerical models developed for each process. The Plata-Piwnik criterion was used in order to define a quantitative parameter taking into account the effectiveness of the bonding. Excellent predictive capability of the network is obtained for each process.
Finite-element simulation of residual stress induced by split-sleeve cold-expansion process of holes
2008
A three-dimensional finite-element simulation was conducted for a split-sleeve cold-expansion process in order to determine the residual stress field around an expanded hole. The commercial FEA software DEFORM-3D™, a Lagrangian implicit code designed for metal forming processes, was used to model the cold-expansion process of a fastener hole. The results show a through-thickness residual stress field in good agreement with the analytical solution developed by Guo. Moreover, the simulation has highlighted the effect of the split sleeve and the plate thickness on the residual stress field. © 2007 Elsevier B.V. All rights reserved.
Analytical bonding criteria for joint integrity prediction in friction stir welding of aluminum alloys
2014
Abstract In this study, two bonding criteria, previously used for porthole die extrusion, are applied to FSW starting from the local value of the main field variables calculated through a specifically developed 3D numerical model of the process. Their applicability and effectiveness have been assessed through an experimental and numerical campaign carried out with the main process parameters varying in a wide range. The pressure–time–flow criterion was demonstrated to be better suited for FSW processes when large welding speed is used.
