Yang, Weilai. "Pricing Network Resources for Differentiated Service Networks." Diss., Georgia Institute of Technology, 2004. http://hdl.handle.net/1853/5227.

Texte intégral

Résumé :

We developed a price-based resource allocation scheme for Differentiated Service (DiffServ) data networks. The DiffServ framework was proposed to provide multiple QoS classes over IP networks. Since the provider supports multiple service classes, we need a differentiated pricing scheme, as supposed to the flat-rate scheme employed by the Internet service providers of today. Charging efficiently is a big issue. The utility of a client correlates to the amount of bandwidth allocated. One difficulty we face is that determining the appropriate amount of bandwidth to provision and allocate is probl

Résumé :

Most rural areas of developing countries are faced with problems like shortage of doctors in hospitals, illiteracy and poor power supply. Because of these issues, Information and Communication Technology (ICT) is often sees as a useful solution for these areas. Unfortunately, the social environment is often ignored. This leads to inappropriate systems being developed for these areas. The aims of this thesis were firstly, to learn how a communication system can be built for a rural telehealth environment in a developing country, secondly to learn how users can be supported to use such a system.

Résumé :

Service composition has risen from the need to make information systems more flexible and open. The Service Oriented Architecture has become the reference architecture model for applications carried by the impetus of Internet (Web). In fact, information systems are able to expose interfaces through the Web which has increased the number of available Web services. On the other hand, with the emergence of the Web 2.0, service composition has evolved toward web users with limited technical skills. Those end-users, named Y generation, are participating, creating, sharing and commenting content thr

Résumé :

Visual analytics, defined as "the science of analytical reasoning facilitated by interactive visual interfaces," emerged several years ago as a new research field. While it has seen rapid growth for its first five years of existence, the main focus of visual analytics research has been on developing new techniques and systems rather than identifying how people conduct analysis and how visual analytics tools can help the process and the product of sensemaking. The intelligence analysis community in particular has not been fully examined in visual analytics research even though intelligence anal

However, although these places are conserved for all, they are not enjoyed by all. As with other conservation agencies, the NPS finds itself increasingly concerned with building relevance with diverse potential stewards. In cities, where 80% of the U.S. population and 40% of the NPS portfolio is based, there is a prime opportunity to build relevance with large, diverse, and proximate audiences. Rec

Opinion leaders are important political players who bridge the gap between the political elite and the general public. Traditionally opinion leaders use social pressure and social support via interpersonal communication to personally influence the opinions, attitudes and behaviours of their everyday associates (who make up the general public). However, in a hybrid media system opinion leaders have access to added channels which mean they can communicate with audiences beyond their everyday associates and/or engage in non-interpersonal interactions, potentially setting the stage for opinion lea

Résumé :

This case study examines the James 1:27 Trust as an information, communication and technology response to the plight of orphans and vulnerable children within the context of an HIV and AIDS epidemic. The James 1:27 Trust demonstrates how social networks can be mobilized in support of children at risk. The use of business information and management systems to administer concepts such as “virtual adoption” is deemed an important innovative contribution. The James 1:27 Trust and its model is studied as a contributor in finding solutions to scale and multiply levels of care by community and

Résumé :

Within the context of social networks, existing methods for document classification tasks typically only capture textual semantics while ignoring the text’s metadata, e.g., the users who exchange emails and the communication networks they form. However, some work has shown that incorporating the social network information in addition to information from language is useful for various NLP applications, including sentiment analysis, inferring user attributes, and predicting interpersonal relations. In this thesis, we present empirical studies of incorporating social network information fr

Résumé :

My dissertation focuses on the strategic implications of the link between organizational culture and social network structure. I study their role in the process of knowledge transfer and diffusion, organizational memory, and organizational design. More broadly, I examine the way that social structure influences the information environment, and what effect this has on organizational learning. I focus in particular on the process of cultural evolution. My dissertation leverages digitization as a phenomenon of inherent interest and as an empirical setting that can improve our theoretical

Résumé :

This study examined how online social networking (OSN) leads to increased communication and collaboration across inter-firm boundaries. This online social networking behaviour represents significant opportunities to firms in the form of improved problem-solving, increased collaborative innovation and enhanced engagement with stakeholders. There are also risks inherent in the widespread use of OSNs, such as the loss of control over information flows to individuals outside the organization, potential damage to the reputation of brands and organizations, and loss of productivity due to excessive

Indiana University-Purdue University Indianapolis (IUPUI)<br>The reliability of information in health social network sites (HSNS) is an imperative concern since false information can cause tremendous damage to health consumers. In this thesis, we introduce a trust framework which captures both human trust level and its uncertainty, and also present advantages of using the trust framework to intensify the dependability of HSNS, namely filtering information, increasing the efficiency of pharmacy marketing, and modeling how to monitor reliability of health information.

M. Tech. Business Information Systems<br>The growing trends and the rapid developments of technological innovation have led to a new way of communication. These developments have seen individuals and organizations spending a lot of money on technological devices, software and applications much higher than ever before. On the other hand, institutions of learning are also advancing with technological innovations by shifting away from the face-to-face teaching and communicating with learners, to the use of Learning Management Systems (LMS). Amidst these challenges, these institutions of learning

Résumé :

Scalable and accurate analysis of networks is essential to a wide variety of existing and emerging network systems. Specifically, network measurement and analysis helps to understand networks, improve existing services, and enable new data-mining applications. To support various services and applications in large-scale networks, network analytics must address the following challenges: (i) how to conduct scalable analysis in networks with a large number of nodes and links, (ii) how to flexibly accommodate various objectives from different administrative tasks, (iii) and how to cope with the dy
