Fusion of digital television, broadband Internet and mobile communications,Part I: Enabling technologies

INTERNATIONAL JOURNAL OF SATELLITE COMMUNICATIONS AND NETWORKING, Issue 4 2007
F. L. C. Ong
Abstract The introduction of digital video broadcasting (DVB) satellite systems has become an important tool for future mobile communication and is currently a focus in several research areas such as the integration of DVB satellite systems with different wireless technologies. This tutorial consists of two parts, Enabling technologies and Future service scenarios, which aims to provide an introduction to the current state-of-the-art of DVB standards over satellite and its fusion with mobile and Internet technologies. This paper, Enabling technologies, focuses on providing an overview of the different technologies and issues that facilitates better understanding of the current and future operational scenarios, whereas the second paper, Future service scenarios will emphasize future research directions in this research area. In the first part, the paper will initially be focused on the introduction of different DVB satellite systems, i.e. DVB- via satellite (DVB-S), DVB return channel by satellite (DVB-RCS) and second-generation DVB system for broadband satellite services (DVB-S2). This is then followed by a description of the different Internet Protocol (IP) technologies used to support macro- and micro-mobility and the migration strategies from IP version 4 (IPv4) to IP version 6 (IPv6). Finally, the different security mechanisms for the DVB system and end-to-end satellite network are addressed. Copyright © 2007 John Wiley & Sons, Ltd. [source]

Enabling technologies to improve area-wide integrated pest management programmes for the control of screwworms

MEDICAL AND VETERINARY ENTOMOLOGY, Issue 2009
A. S. ROBINSON
Abstract The economic devastation caused in the past by the New World screwworm fly Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) to the livestock industry in the U.S.A., Mexico and the rest of Central America was staggering. The eradication of this major livestock pest from North and Central America using the sterile insect technique (SIT) as part of an area-wide integrated pest management (AW-IPM) programme was a phenomenal technical and managerial accomplishment with enormous economic implications. The area is maintained screwworm-free by the weekly release of 40 million sterile flies in the Darien Gap in Panama, which prevents migration from screwworm-infested areas in Columbia. However, the species is still a major pest in many areas of the Caribbean and South America and there is considerable interest in extending the eradication programme to these countries. Understanding New World screwworm fly populations in the Caribbean and South America, which represent a continuous threat to the screwworm-free areas of Central America and the U.S.A., is a prerequisite to any future eradication campaigns. The Old World screwworm fly Chrysomya bezziana Villeneuve (Diptera: Calliphoridae) has a very wide distribution ranging from Southern Africa to Papua New Guinea and, although its economic importance is assumed to be less than that of its New World counterpart, it is a serious pest in extensive livestock production and a constant threat to pest-free areas such as Australia. In the 1980s repeated introductions and an expansion of Old World screwworm populations were reported in the Middle East; in the 1990s it invaded Iraq and since late 2007 it has been reported in Yemen, where a severe outbreak of myiasis occurred in 2008. Small-scale field trials have shown the potential of integrating the SIT in the control of this pest and various international organizations are considering using the release of sterile insects as part of an AW-IPM approach on a much wider scale. Wohlfahrtia magnifica (Schiner) (Diptera: Sarcophagidae) is a screwworm of temperate regions, which, although of limited agricultural importance, has invaded several new locations in the past few years. This special issue reports on the results of a 6-year project funded by the Joint Food and Agriculture Organization of the United Nations/International Atomic Energy Agency (FAO/IAEA) Programme of Nuclear Techniques in Food and Agriculture entitled ,Enabling Technologies for the Expansion of the SIT for Old and New World Screwworm'. A major goal of the project was to better understand population genetic variation in screwworms as an aid to the identification of isolated populations. The project also addressed issues related to genetic sexing, cuticular hydrocarbons, population dynamics, genetic transformation and chromosome analysis. [source]

GOLD infrastructure for virtual organizations

CONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 11 2008
P. Periorellis
Abstract The paper discusses the GOLD project (Grid-based Information Models to Support the Rapid Innovation of New High Value-Added Chemicals) whose principal aim is to carry out research and development into enabling technologies to support the formation, operation and termination of virtual organizations. The paper discusses the outcome of this research, which is the GOLD Middleware infrastructure. The infrastructure has been implemented in the form of a set of Middleware components, which address issues such as trust, security, contract monitoring and enforcement, information management and coordination. We discuss all these issues in turn and more importantly we demonstrate how current WS standards can be used to implement these issues. In addition, the paper follows a top down approach starting with a brief outline on the architectural elements derived during the requirements engineering phase and demonstrates how these elements were mapped onto actual services that were implemented according to service-oriented architecture principles and related technologies.

Tools for planning and coordinating development of medical countermeasures in the public sector

DRUG DEVELOPMENT RESEARCH, Issue 4 2009
Ian Manger
Abstract In spite of significant increases in biodefense spending in the 7 years since the 2001 anthrax attacks, the United States may not yet be fully prepared to respond effectively to many potential biothreats. The principal reasons appear to be that: (1) the problem is extremely complex, and the metrics for success are often unclear; (2) although the US Congress has allocated substantial resources for this effort, these funds are insufficient for the task as initially conceived, i.e., "one drug for each bug;" and (3) there is insufficient coordination among the many agencies working to achieve the goal of protecting the nation from biothreats. In the last few years, much of the biodefense community has come to recognize that an approach that focuses on developing and stockpiling a medical countermeasure (MCM) for each possible biothreat agent is unachievable for reasons of cost, time, and the sheer diversity of emerging threats. Promising alternative models are emerging, including broad spectrum and technology platform approaches, but the requisite cross-agency planning and coordination, although improving, is still problematic. We have developed a set of software tools and methods for using them that could support the desired coordination and that could also provide for more rapid, comprehensive, and shared identification of key enabling technologies for accomplishing the development of effective medical countermeasures in time to counter or prevent a biothreat. The tools and methods could also make possible a collaborative public-private partnership for the development of MCM, which many believe is critical to success.

Nanostructured Biomaterials for Regeneration,

ADVANCED FUNCTIONAL MATERIALS, Issue 22 2008
Guobao Wei
Abstract Biomaterials play a pivotal role in regenerative medicine, which aims to regenerate and replace lost/dysfunctional tissues or organs. Biomaterials (scaffolds) serve as temporary 3D substrates to guide neo tissue formation and organization. It is often beneficial for a scaffolding material to mimic the characteristics of extracellular matrix (ECM) at the nanometer scale and to induce certain natural developmental or/and wound healing processes for tissue regeneration applications. This article reviews the fabrication and modification technologies for nanofibrous, nanocomposite, and nanostructured drug-delivering scaffolds. ECM-mimicking nanostructured biomaterials have been shown to actively regulate cellular responses including attachment, proliferation, differentiation, and matrix deposition. Nanoscaled drug delivery systems can be successfully incorporated into a porous 3D scaffold to enhance the tissue regeneration capacity. In conclusion, nanostructured biomateials are a very exciting and rapidly expanding research area, and are providing new enabling technologies for regenerative medicine. [source]

Parlay-based service provision in circuit- and packet-switched telecommunications networks

INTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS, Issue 1 2004
Andreas E. Papadakis
Abstract The spectrum of potential value added services over Internet telephony is wide, but the current service provision solutions are inadequate or proprietary. The nature of Internet differs significantly from that of circuit switched network, however, VoIP architectures can capitalize service control architectures in the PSTN world. We describe such an architecture based on the intelligent network and the Parlay, employing distributed objects and mobile agents as enabling technologies. This architecture has been implemented in the PSTN and the Internet and it has provided a framework for service provisioning, augmenting the space of supported services.

Sensory enabling technology acceptance model (SE-TAM): A multiple-group structural model comparison

PSYCHOLOGY & MARKETING, Issue 9 2008
Jiyeon Kim
Sensory enabling technology (SET) can deliver product information that is similar to the information obtained from direct product examination, thus reducing product risk. In addition, the interactivity and customer involvement created by sensory enabling technologies can enhance the entertainment value of the online shopping experience. The proposed model examined this dual role of sensory experience enablers in the online soft goods shopping process for three types of sensory enabling technologies that are widely applied in online retail sites. The results provided empirical support for perceived usefulness and perceived entertainment value as strong predictors of consumers' attitudes toward using all three of the sensory enabling technologies tested in this study. The impact of perceived ease of use differed by technology. Attitudes toward using sensory enabling technologies had a significant impact on the actual use of all three SETs; however, the impact of technology anxiety and innovativeness on the use of SET also appeared to differ by technology. Virtual try-on played a strong hedonic role, increasing the entertainment value of the online shopping process, whereas 2D views (larger view and alternate views) showed a strong functional role. The 3D rotation view served both functional and hedonic roles. The results indicate that each sensory enabling technology makes a unique contribution to online shopping,either by reducing product risk perceptions or by increasing perceived entertainment value. © 2008 Wiley Periodicals, Inc.

Material and digital design synthesis

ARCHITECTURAL DESIGN, Issue 2 2006
Michael Hensel
Abstract The advanced material and morphogenetic digital design techniques and technologies presented in this journal call for a higher level methodological integration, which poses a major challenge for the next generation of multidisciplinary architectural research and projects. This collaborative task encompasses the striving for an integrated set of design methods, generative and analytical tools and enabling technologies that facilitate and instrumentalise evolutionary design, and evaluation of differentiated material systems towards a highly performative and sustainable built environment. Michael Hensel and Achim Menges describe recent progress towards a higher-level design synthesis of material self-organisation, digital morphogenesis, associative parametric modelling and computer-aided manufacturing (cam) on the basis of two works produced within the context of the Emergent Technologies and Design Masters programme at the Architectural Association in London, and a recent competition entry by Scheffler + Partner Architects and Achim Menges.

A large-scale monitoring and measurement campaign for web services-based applications

CONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 10 2010
Riadh Ben Halima
Abstract Web Services (WS) can be considered as the most influent enabling technology for the next generation of web applications. WS-based application providers will face challenging features related to nonfunctional properties in general and to performance and QoS in particular. Moreover, WS-based developers have to provide solutions to extend such applications with self-healing (SH) mechanisms as required for autonomic computing to face the complexity of interactions and to improve availability. Such solutions should be applicable when the components implementing SH mechanisms are deployed on both or only one platform on the WS providers and requesters sides depending on the deployment constraints. Associating application-specific performance requirements and monitoring-specific constraints will lead to complex configurations where fine tuning is needed to provide SH solutions. To contribute to enhancing the design and the assessment of such solutions for WS technology, we designed and implemented a monitoring and measurement framework, which is part of a larger Self-Healing Architectures (SHA) developed during the European WS-DIAMOND project. We implemented the Conference Management System (CMS), a real WS-based complex application. We achieved a large-scale experimentation campaign by deploying CMS on top of SHA on the French grid Grid5000. We experienced the problem as if we were a service provider who has to tune reconfiguration strategies. Our results are available on the web in a structured database for external use by the WS community. Copyright © 2010 John Wiley & Sons, Ltd. [source]

Microfluidic technologies for MALDI-MS in proteomics

ELECTROPHORESIS, Issue 18 2006
Don L. DeVoe Professor
Abstract The field of microfluidics continues to offer great promise as an enabling technology for advanced analytical tools. For biomolecular analysis, there is often a critical need to couple on-chip microfluidic sample manipulation with back-end MS. Though interfacing microfluidics to MS has been most often reported through the use of direct ESI-MS, there are compelling reasons for coupling microfluidics to MALDI-MS as an alternative to ESI-MS for both online and offline analysis. The intent of this review is to provide a summary of recent developments in the integration of microfluidic systems with MALDI-MS, with an emphasis on applications in proteomics. Key points are summarized, followed by a review of relevant technologies and a discussion of outlook for the field. [source]

A multimedia-enhanced collaborative learning environment

JOURNAL OF COMPUTER ASSISTED LEARNING, Issue 1 2000
C-K. Looi
Abstract The proliferation of the Internet has brought about the notion of online virtual communities. One enabling technology for online communities is multiuser environments such as Multi-User Dimensions (MUDs) and Object-Oriented MUDS (MOOs). These text-based collaborative learning environments have recently have been integrated with the World Wide Web, thus harnessing the graphics and multimedia-rich environments available therein. Learners can directly experience, manipulate, and create objects in their rich multimedia form. MUDs and MOOs are augmented with synchronous collaboration technology that provided simultaneous control and viewing of shared documents and applications. In this paper, we describe a multimedia-enhanced MOO system called SpaceALIVE! and our experiences from a pilot project involving Singapore students who use SpaceALIVE! as a collaborative learning environment are reported.

Mutagenic Safety and Fatty Liver Improvement of Nanonized Black Soybeans in Senescence-Accelerated Prone-8 Mice

JOURNAL OF FOOD SCIENCE, Issue 5 2010
J.-W. Liao
Abstract:, Nanotechnology, as a new enabling technology, has the potential to revolutionize food systems. However, much attention has been focused on nanoparticle foods due to their potential physiological properties. This study was aimed to evaluate the mutagenic safety and fatty liver improvement of black soybean in senescence-accelerated mice (SAMP8). The mutagenic activity of black soybeans was investigated using the Ames test (Salmonella Typhimurium,TA98, 100, 102, and 1535). Furthermore, senescence-accelerated prone-8 mice (SAMP8) have been reported to display spontaneous fatty liver. Male SAMP8 mice were divided into control and supplemented with 10% micronized or nanonized black soybeans diet and fed for 12 wk. The results revealed that the Ames test of micronized and nanonized black soybeans exhibited no mutagenicity. Administration of black soybeans to mice showed no effects on food intake and body and organ weights. The nanonized black soybean group had a lower degree of spontaneous fatty liver, alanine aminotransferase, and thiobarbituric acid-reactive substance concentrations, and had enhanced superoxide dismutase, catalase, and glutathione peroxidase activities of livers when compared with the SAMP8 control and micronized black soybean groups. The mice fed with black soybeans had significantly lower triglyceride concentrations than the SAMP8 control group. The results of this study suggest that nanonized black soybeans have no side effects and, moreover, may minimize liver lesions in SAMP8 mice. [source]

The design and use of WSDL-Test: a tool for testing Web services

JOURNAL OF SOFTWARE MAINTENANCE AND EVOLUTION: RESEARCH AND PRACTICE, Issue 5 2007
Harry M. Sneed
Abstract Web services are becoming increasingly important to many businesses, especially as an enabling technology for systems that adopt a service-oriented architecture approach to their development. However, testing Web services poses significant challenges. This paper describes the design and use of WSDL-Test, a tool designed specifically for this purpose. A key feature of WSDL-Test is its ability to simulate the actual usage of Web services in a controlled environment. This enables WSDL-Test to generate requests and validate responses in a rapid and reliable manner. To illustrate the use of WSDL-Test, the paper also discusses our experience using the tool on a real-world online eGoverment application. Copyright © 2007 John Wiley & Sons, Ltd. [source]

RFID research and testing for packages of apparel, consumer goods and fresh produce in the retail distribution environment

PACKAGING TECHNOLOGY AND SCIENCE, Issue 2 2008
S. P. Singh
Abstract Radio frequency identification (RFID) is a term used for any device that can be sensed at a distance by radio frequencies with few problems of obstruction. The origins of the term lie in the invention of tags that reflect or retransmit a radio-frequency signal. According to a recent article by Forrester Research, the minimal ,Slap and Ship' approach to RFID compliance will cost an individual company between $2 million and $20 million. Because retailers like Wal-Mart plan to share with their suppliers all the RFID-generated data points (from when a case/pallet enters their distribution centre until it leaves their stockroom), suppliers will eventually be able to use this data as a powerful forecasting tool. RFID is an enabling technology that can potentially facilitate a real-time, end-to-end supply chain visibility system. Suppliers who integrate full-scale RFID systems will realize efficiencies in time, material movement, inventory planning, shipping and warehousing both internally and externally. This paper provides a brief overview of the RFID technology, mandates by retailers and federal agencies, advances towards global standardization and typical consumer level RFID applications, and discusses RFID initiatives taken by some of the global leaders in apparel, consumer goods and fresh produce industries.
