Using Factor Analysis Techniques to Find Out Objective Video Quality Metrics for Live Video Streaming over Cloud Mobile Media Services

2016

The increased adoption of smartphones, the access to mobile broadband networks and the availability of public Clouds allow new multimedia services, called Cloud Mobile Media Services. Under this new architecture the proliferation of live video streaming applications and the Quality of Experience (QoE) given by the final user are an issue, due to the higher and variable delay, as result of the virtualization methods used in the Clouds. Thus in this paradigm new challenges appear related to keep and estimate a good QoE in terms of a standarized subjective video quality called Mean Opinion Score (MOS). In this paper we analyze different approaches based on Factor Analysis techniques to estimat…

Sources of Dissatisfaction: Mobile Interaction with the Real World and Other Mobile Internet Applications

2013

Current consumer-level mobile Internet applications involve many potential sources of dissatisfaction. Studying these sources is necessary, especially for newer application areas such as mobile interaction with the real world. This study combined previous studies to form a categorization framework of dissatisfaction sources and gathered qualitative data using critical incident technique and overall evaluation questionnaire to describe the sources in detail. This article proposes insights into characteristics, temporality, and combinations of sources. peerReviewed

Designing a mobile app for museums according to the drivers of visitor satisfaction

2013

The aim of this study is to identify the key factors as antecedents of visitor satisfaction for the design of a mobile app for museums. To our aim we use the Kano model that allows to categorize service attributes according to how they are perceived by customers and to estimate their impact on customer satisfaction. We collected qualitative data trough 300 questionnaires administered to tourists visiting the Sicilian cities of Palermo and Trapani over a period of 3 months (October- December 2012). The results of our analysis can be relevant for museum and public managers to plan strategic and operative activities, for researcher in the field of touristic marketing, for application developer…

JamMo - Developmentally designed software for children’s mobile music-making

2009

Mobile learning is one of the most recent branches in educational research. In contrast to traditional classroom learning, mobile learning extends outside the classroom, allowing mobility and flexible interaction between formal and informal learning. Up to this date, only few music based mobile applications have been developed for educational purposes and especially for young children. In the present study, software JamMo will be designed for Nokia N810 Internet tablet. JamMo aims at child-centred, intelligent musical engineering and pedagogical design of stand-alone, ad hoc and networked creative music making. It is targeted to 3–12-year-old children including those with moderate learning …

LA CHLAMYDIA PNEUMONIAE È CORRELABILE CON LA ROTTURA DELLA PLACCA ATEROSCLEROTICA? RUPTURE OF THE ATHEROSCLEROTIC PLAQUE: IS CHLAMYDIA PNEUMONIAE A P…

2006

Background. The natural history of atherosclerosis has not clearly been elucidated yet. Some works reported that flogosis plays a role in plaque instability. Why does this inflammatory process start? We investigated the correlation between Chlamydia pneumoniae acute infection and plaque rupture. Methods. We compared blood concentrations of IgM anti-Chlamydia pneumoniae in patients affected by acute myocardial infarction (AMI) and in patients affected by stable angina. Results. Our results showed a minimal statistical difference, with a more positive value in patients with AMI. Subsequently, the group affected by AMI was divided into two subgroups with and without plaque rupture: the subgrou…

De la vente au conseil : l'irréstible évolution du commercial du secteur automobile

2013

Dans les contextes mouvementés du secteur de l'automobile, de la concurrence exacerbée, de l'émergence du e-commerce, du développement de stratégies marketing par les constructeurs visant à attirer le maximum de clients, que deviennent les vendeurs? Quelles sont aujourd'hui leur place et leurs pratiques professionnelles? Et comment ces évolutions sont-elles soutenues par les employeurs en termes de politiques et de pratiques gestionnaires ? Pour apporter des éléments de réponses à ces questions, ce texte s'appuie sur une vingtaine d'entretiens de salariés et de leurs responsables hiérarchiques (supérieurs directs, dirigeants) menées dans deux entreprises de nature et de taille très différen…

NFC-maksaminen : mahdollisuudet ja haasteet käyttäjän näkökulmasta

2013

Mobiilit päätelaitteet ja niitä käyttävien kuluttajien määrä on lisääntynyt nopeasti viime vuosien aikana, mikä tuo uusia mahdollisuuksia erilaisille mobiilin maksamisen sovelluksille. Tässä tutkielmassa paneuduttiin kirjallisuuskatsauksen avulla Near Field Communication -teknologian eli NFC:n ominaisuuksiin sekä NFC-maksamiseen liittyvien mahdollisuuksien ja haasteiden erityispiirteisiin käyttäjän näkökulmasta. Tutkimustuloksina todettiin NFC-maksamisella olevan huomattava määrä kehittäjiä ja muita tukijoita takanaan, mikä edesauttaa nopeaa teknologista kehitystä. NFC:llä vaikuttaisikin olevan hyvät mahdollisuudet kilpailla muiden elektronisten maksutapojen kanssa. NFC-maksamisen helppous …

Uptake from water, biotransformation, and biliary excretion of pharmaceuticals by rainbow trout.

2011

An urgent need exists to assess the exposure of fish to pharmaceuticals. The aim of the present study was to assess the uptake and metabolism of waterborne pharmaceuticals in rainbow trout (Oncorhynchus mykiss). A further objective was to determine the possibility of monitoring exposure to low levels of pharmaceuticals by bile assays. Rainbow trout were exposed for 10 d under flow-through conditions to mixtures of five pharmaceuticals (diclofenac, naproxen, ibuprofen, bisoprolol, and carbamazepine) at high and low concentrations. The low concentration was used to mimic the conditions prevailing in the vicinity of the discharge points of wastewater treatment plants. The uptake and the biocon…
