A video server on the Internet usually provides a short version of a video clip, a video abstraction, in order to provide highlights or the overall story to users as quickly as possible. However, since it is statically generated by content providers using domain-dependent heuristics, it cannot satisfy all users simultaneously. This paper proposes a domain-independent video abstraction algorithm...

ReceivedOct 20 th , 2012 Accepted Oct 31 th , 2012 During the last decade, there has been a major paradigm shift in the way the software services are being provided to the enterprise and corporate sector. Instead of using on-premises LOB (Line of Business) applications, corporations and enterprises are switching to off-premises host applications that are now being offered as a service by severa...

In this work we analyse the relation between hierarchical distancebased clustering and the concepts that can be obtained from the hierarchy by generalisation. Many inconsistencies may arise, because the distance and the conceptual generalisation operator are usually incompatible. To overcome this, we propose an algorithm which integrates distance-based and conceptual clustering. The new dendrog...

Recently, operators have resorted to femtocell networks to enhance indoor coverage and increase system capacity. Nevertheless, to successfully deploy such solution, efficient resource-allocation algorithms and interference mitigation techniques should be deployed. The new applications delivered by operators require large amounts of network bandwidth. Although, some customers may want to pay mor...

AMUDALA BHASKER, AJAY BABU. Tiered-Service Fair Queueing (TSFQ): A Practical and Efficient Fair Queueing Algorithm. (Under the direction of Professor George N. Rouskas.) A router in today’s Internet has to satisfy two important properties in order to efficiently provide the Quality of Service (QoS) requested by the users. It should be fair among flows and also have low operational complexity. T...

Infrastructure-as-a-Service has revolutionized the manner in which users commission computing infrastructure. Coupled with Big Data platforms (Hadoop, Cassandra), IaaS has democratized the ability to store and process massive datasets. For users that need to customize or create new Big Data stacks, however, readily available solutions do not yet exist. Users must first acquire the necessary clo...

The application of ICT to learning, the Web 2.0 trends and the widespread use of technologies such as mobile devices make it necessary to provide new solutions to satisfy the needs of learners. Such solutions should treat the students as the centre of the learning process. The students should be able to decide which tools they will use to learn, and the learning institution must consider the be...
