An interest-aware video streaming platform: Shaping its architecture to better suit users' demands
2014
This paper investigates how a p2p television platform can take advantage of the presence of frequent channel viewers to grant them a more satisfying service than to less regular spectators. The idea we explore is to learn beforehand about the users’ interests, in order to cluster them in groups that display different behaviors; then, the video chunk scheduling algorithm of the p2p overlay is altered, with the aim of serving frequent spectators in a privileged manner, providing them with a faster access to the selected channel. An analytical model is developed, to capture the difference in startup delay that the proposed changes introduce; several additional performance metrics are numerical…
Transformations in Lifelong Guidance Provision
2012
In this chapter, the transformations taking place at the different levels of guidance provision are analyzed. The aim was to provide a tool to examine the interface between multisectoral guidance practice and policy development. On the basis of earlier research on regional guidance networks, a model is introduced in which schools, social, health, and public employment services can jointly design, implement, and evaluate guidance services. The model for Networked Guidance Service Provision (NEGSEP) focuses separately on the developmental needs of guidance services visible to clients, both with regard to service delivery and strategic dimensions. Along this line, a framework for networked gui…
A System Dynamics Approach to Enhance Tourism Service Delivery Performance through Value Co-Creation

Improvement of a Service Level Negotiation Protocol using Formal Verification
2013
International audience; The goal of the pervasive connectivity is to enable mobile users to be permanently connected to the Internet. Mobile users are often connected to wireless networks and consuming services that require quality of service guarantees. Accessing services using wireless technologies may make the service delivery vulnerable to security attacks because of the open medium of these technologies. In this context, we need to guarantee both quality of service and security for mobile users communications. In this paper, we present a protocol for service level negotiation which covers both quality of service and security and assigns a profile to each user in order to optimize and a…
Absorptive capacity and its impact on innovation and performance: findings from SEM and fsQCA
2018
Innovation can provide sustainable competitive advantages to service companies that consider the absorption of external knowledge a key strategic issue. Using the four dimensions of absorptive capacity, this study examined the impact of absorptive capacity on innovation in service delivery processes and explored how this innovation influences business performance. Structural equation modeling (PLS-SEM) and fuzzy-set qualitative comparative analysis (fsQCA) were applied to a sample of 134 companies drawn from the Colombian tourism sector. The results of the SEM indicate that innovation in service delivery processes is positively influenced by two of the four dimensions of absorptive capacity…
Morphological characterization of calanchi (badland) hillslope connectivity
2018
Calanchi, a type of Italian badlands created by a combination of water erosion processes and local geomorphological and tectonic controls, is a striking example of long-term landscape evolution. In small temporal/spatial scales, the calanchi exhibit many of the geomorphic processes and landforms that may be observed in fluvial landscapes; hence, they may be considered as microbasins where geomorphic dynamics and landscape features can be related. The goal of this research is testing the use of simple morphometric variables for assessing sediment connectivity of calanchi landforms. In order to detect the morphological characteristics controlling the landscape connectivity of calanchi basins,…
Nanocarriers to targeted terapy: a goal for biomedical applications.
2011
The reasons for the growing interest in biomaterials for application in the biomedical field are related to need to find alternative and more effective than conventional procedures used in drug treatment of several diseases. The traditional methods of drug delivery has limitations due to the drug’s toxicity in the body. The development of nanocarriers, which can be functionalized and loaded with drugs or genetic material and can be released into the body with a controlled mechanism, was a real goal in the field of biomedical applications. Synthetic hydrogels have found many applications especially in tissue-engineering scaffolds, as carriers for implantable and drug delivery devices. Hydrog…
