CHORUS Deliverable 2.1: State of the Art on Multimedia Search Engines

Based on the information provided by European projects and national initiatives related to multimedia search as well as domains experts that participated in the CHORUS Think-thanks and workshops, this document reports on the state of the art related to multimedia content search from, a technical, and socio-economic perspective. The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines. From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research

A framework for the dynamic management of Peer-to-Peer overlays

Peer-to-Peer (P2P) applications have been associated with inefficient operation, interference with other network services and large operational costs for network providers. This thesis presents a framework which can help ISPs address these issues by means of intelligent management of peer behaviour. The proposed approach involves limited control of P2P overlays without interfering with the fundamental characteristics of peer autonomy and decentralised operation. At the core of the management framework lays the Active Virtual Peer (AVP). Essentially intelligent peers operated by the network providers, the AVPs interact with the overlay from within, minimising redundant or inefficient traffic, enhancing overlay stability and facilitating the efficient and balanced use of available peer and network resources. They offer an “insider‟s” view of the overlay and permit the management of P2P functions in a compatible and non-intrusive manner. AVPs can support multiple P2P protocols and coordinate to perform functions collectively. To account for the multi-faceted nature of P2P applications and allow the incorporation of modern techniques and protocols as they appear, the framework is based on a modular architecture. Core modules for overlay control and transit traffic minimisation are presented. Towards the latter, a number of suitable P2P content caching strategies are proposed. Using a purpose-built P2P network simulator and small-scale experiments, it is demonstrated that the introduction of AVPs inside the network can significantly reduce inter-AS traffic, minimise costly multi-hop flows, increase overlay stability and load-balancing and offer improved peer transfer performance

Information and communication technology as a tool for craft market traders in promoting community tourism.

Doctoral Degree. University of KwaZulu-Natal, Durban.This is an interdisciplinary study, taking information and communication technology (ICT) as a point of departure, incorporating tourism, art and craft, e-business and community development as the field of knowledge. The craft market traders around Hluhluwe-Imfolozi Park (HIP) lack essential business tools, such as ICT devices, to improve craft market trading with tourists, nationally and internationally, without the intervention of the middleman, who could help to enable sustainable community development. Craft market traders manufacture or produce their crafts using natural resources such as Juncus maritimus and thatch grass for mats, bowls and hats. They use tree trunks and natural wood for sculptures and meat platters. Most of these natural resources are already depleted outside the protected areas and local communities have to rely on natural resources inside the park. Harvesting without permission in the park is illegal. The researcher has provided a step-by-step outline on how she intends to execute the logical chain of events that would produce solutions to the problems identified and answers to critical questions. The researcher examined the historical background of craft, the cultural background of the craft market traders and ICT devices that can improve their business performance. The business sector, as well as government, played a role in the success of this research. ABSA Bank and the Department of Economic Development were engaged. There are possible positive outcomes, such as the installation of an ABSA automatic teller machine in HIP. The overall objective of the research was to find solutions that can enhance the standard of living of the local communities, by increasing the employment rate in terms of craft market traders selling their craft, nationally and internationally

Identification and assessment of opportunities and threats for the Circular Economy arising from E-commerce

The present study identifies, describes and assesses in detail opportunities and threats for the Circular Economy arising from E-commerce. A broad literature research and direct stakeholder input led to the identification of 18 opportunities and 23 threats for the Circular Economy, allocated to 7 different clusters. Most of the identified threats refer to “Logistics and transport”, while opportunities refer mainly to the topics “Accessibility of information” and “Digitalisation”. By means of a comparative assessment in the current situation and future optimistic and pessimistic potential developments, the direct and indirect effects of the opportunities and threats have been evaluated, with specific focus on 7 selected product categories. In total, 11 opportunities and 16 threats have been assessed as either medium or highly relevant. The assessment revealed that most of the threats classified as highly relevant belong to the cluster “Logistics and transport”, including induced parcel transport, parcel return and inefficient transport, while most of the highly relevant opportunities are to be found in the cluster “Accessibility of information”, as in the case of second-hand commerce or product portfolio.JRC.B.5-Circular Economy and Industrial Leadershi

Software Takes Command

This book is available as open access through the Bloomsbury Open Access programme and is available on www.bloomsburycollections.com. Software has replaced a diverse array of physical, mechanical, and electronic technologies used before 21st century to create, store, distribute and interact with cultural artifacts. It has become our interface to the world, to others, to our memory and our imagination - a universal language through which the world speaks, and a universal engine on which the world runs. What electricity and combustion engine were to the early 20th century, software is to the early 21st century. Offering the the first theoretical and historical account of software for media authoring and its effects on the practice and the very concept of 'media,' the author of The Language of New Media (2001) develops his own theory for this rapidly-growing, always-changing field. What was the thinking and motivations of people who in the 1960 and 1970s created concepts and practical techniques that underlie contemporary media software such as Photoshop, Illustrator, Maya, Final Cut and After Effects? How do their interfaces and tools shape the visual aesthetics of contemporary media and design? What happens to the idea of a 'medium' after previously media-specific tools have been simulated and extended in software? Is it still meaningful to talk about different mediums at all? Lev Manovich answers these questions and supports his theoretical arguments by detailed analysis of key media applications such as Photoshop and After Effects, popular web services such as Google Earth, and the projects in motion graphics, interactive environments, graphic design and architecture. Software Takes Command is a must for all practicing designers and media artists and scholars concerned with contemporary media
