Privacy Enhanced Device Access
2012
In this paper we present the case for a device authentication protocol that authenticates a device/service class rather than an individual device. The devices in question are providing services available to the public. The proposed protocol is an online protocol and it uses a pseudo-random temporary identity scheme to provide user privacy.
Techno-economical inspection of high-speed Internet connection for trains
2008
Some attractive service scenarios for Railways' Intelligent Transport Systems (RITS) in three different user segments, that is, passengers, freight companies and train operator's in-house customers, are presented. The case study covers the analysis of customer needs and techno-economic evaluations. The analysis indicates that Flash-OFDM technology provides promising pre-stage solution for the train connections in Finland. Also, the WiMAX-based high-speed Internet access for passengers may be profitable in the most heavily operated railway leg in Finland. The sensitivity analysis shows that the most crucial parameters for the case are `User Share', `Average Revenue per User' and `WiMAX Cell …
Measuring Repurchase Intention on Fashion Online Shopping
2020
The internet has become one of many ways for consumers to shop. With the rapid development of internet connection, online shopping has become increasingly popular around the world. All forms of conveniences available through online businesses have lured consumers to switch from offline shopping to online slowly. This research emphasizes the influence of e-service convenience on customer satisfaction, perceived service value, and repurchase intention on fashion online shopping websites in Surabaya. The sample is taken from 115 Surabaya respondents. The sampling technique uses a non-random sampling technique. The analytical method used is the partial least square (PLS). The results show that …
Healthcare access of immigrants: An integrated ecological framework
2019
Access to healthcare impacts in health, and for its importance it has been conceptualized by different theoretical models. Theories tackling social barriers have been established too. Nevertheless, a lack of theorization about healthcare access of immigrants exists, and there is no theory able to integrate all the scientific literature on this and its impact on the health of immigrants. In order to study the factors relating to the access of immigrants and to guide the development and evaluation of public health interventions, an integrative approach is needed. In this regard, from an ecological perspective healthcare access of immigrants would be shaped by interrelated factors in different…
Exploring web-mediated communication: A genre-based linguistic study for new patterns of doctor–patient interaction in online environment
2016
This paper questions the nature of the communicative event that takes place in online contexts between doctors and web-users, showing computer-mediated linguistic norms and discussing the nature of the participants’ roles. Based on an analysis of 1005 posts occurring between doctors and the users of health service websites, I analyse how doctor–patient communication is affected by the medium and how health professionals overcome issues concerning the virtual medical visit. Results suggest that (a) online medical answers offer a different service from that expected by users, as doctors cannot always fulfill patient requests, and (b) net consultations use aspects of traditional doctor–patient…
Network channel allocation and revenue maximization
2002
This paper introduces a model that can be used to share link capacity among customers under different kind of traffic conditions. This model is suitable for different kind of networks like the 4G networks (fast wireless access to wired network) to support connections of given duration that requires a certain quality of service. We study different types of network traffic mixed in a same communication link. A single link is considered as a bottleneck and the goal is to find customer traffic profiles that maximizes the revenue of the link. Presented allocation system accepts every calls and there is not absolute blocking, but the offered data rate/user depends on the network load. Data arriva…

Inter-provider AAA and Billing of VoIP Users with Token-based Method
2007
With the increasing popularity of wireless LAN technology, providers of real-time voice over IP (VoIP) services, known as voice service providers (VSP), are asking for roaming solutions and AAA (Authentication, Authorization and Accounting) methods that allow users to use their services from any available public Internet access network. In this paper we propose an AAA and billing architecture that allows users of VSPs to have access to the Internet from wired and wireless access networks provided by both traditional carriers, such as 3G providers, and wireless local access network (WLAN) providers. We propose a token-based AAA method that allows users of VoIP services to have their VSPs as …
Analysis and Simulation of the Signaling Protocols for the DiffServ Framework
2006
This paper considers signaling protocols for the DiffServ QoS framework. Originally, DiffServ had no standardized signaling solution, which resulted in the static configuration for the DiffServ domain. However, the dynamic allocation of resources within the domain allows to ensure the per-flow QoS guarantees and achieve better performance. At the moment, several signaling solutions for DiffServ framework are available. Thus, it is crucial to analyse these solutions and interconnections between them. In particular, the RSVP, aggregated RSVP, GIST, COPS, and SIP protocols will be considered. The simulation comprises several scenarios that present that the dynamic allocation of resource within…
Melo
2015
Il Progetto Nazionale, “Liste di Orientamento Varietale dei Fruttiferi - Melo”, ha ormai abbondantemente superato i vent’anni. Ultimamente sta attraversando diverse peripezie, anche se mantiene invariato lo spirito originario, proponendosi come obiettivo la verifica del comportamento vegetativo e produttivo di numerose nuove varietà introdotte in Italia e divulgazione dei risultati ottenuti. Basti pensare che dal 1980 al 2014 sono state registrate al mondo quasi 1700 nuove varietà, il Progetto nazionale ne ha valutate più di 300 a partire dal 1993. Il lavoro di valutazione, riguardante l’”adattabilità”, agronomica e merceologica, del nuovo materiale genetico è affidato a 16 Unità Operative,…
