Objectives: Quality of life, when referring to an individual’s health, is called health-related quality of life. The purpose of this study is to assess self-perceived hearing loss related quality of life of adolescents with hearing loss and its relationship with sex, age sub-groups or school settings with domains of quality of life. Methods: A school based survey was conducted in Tehra...

This paper focuses on enterprise models representing interaction aspects which are very important when modelling networked enterprises . To this aim, a case study concerning an Italian training organization is addressed as a show case, where a re-engineering of the quality management systems where addressed. The main criticalities of cooperation either in the real operative practice and in the ...

We report about an empirical study that investigates the role of different "roomware" configurations on the products and processes of meeting room collaboration. The configurations were realized by different combinations of providing computers and a large interactive electronic whiteboard. In this study, 48 subjects working in teams of four were assigned to three experimental conditions: four w...

Novel, networked information-rich control systems are emerging to provide a stable and cost-efficient operation of future electricity distribution grids. However, the dependence on fault-prone, low-cost, and heterogeneous network technologies and architectures challenges the grid control quality. In this work, we study the impact of varying network QoS on the low voltage grid operation in an el...

In wireless channels, the path loss exponent (PLE) has a strong impact on the quality of links, and hence, it needs to be accurately estimated for the efficient design and operation of wireless networks. In this paper, we address the problem of PLE estimation in large wireless networks, which is relevant to several important issues in networked communications such as localization, energy-effici...

The formidable amount of heterogeneous information, accessed by the networked enterprise through all the available channels, makes it difficult for users to find the right information at the right time and at the right level of detail. Contextual meta-data about the system and the users can be used to reduce this plethora of information, providing high-quality, focussed knowledge to users and a...

As advanced Internet services, networked virtual reality applications impose certain Quality of Service (QoS) requirements, due to rich multimedia content and perceived “real-time” interactivity. Two different representations of QoS are needed at the user/application level and at the communication level, which our approach attempts to relate using as a reference an interconnection model for net...

The growth of computer networks has led to increasing diversity of Internet applications, including streaming media and network games. However, without precise information on how network and system improvements benefit the networked application user, it is difficult to properly assess the benefits of new network treatments or to design the next generation networks that will effectively support ...
