Monitoring wood decay in poles by the vibroacoustic method

Despite recent advances in the development of new materials, wood continues to be used globally for the support of overhead cable networks used by telecommunications and electrical utility companies. As a natural material, wood is subject to decay and will eventually fail, causing disruption to services and danger to public and company personnel. The traditional method of testing poles for decay involves hitting them with a hammer and listening to the sound that results. However, evidence suggests that a large number of poles are replaced unnecessarily and a significant number of poles continue to fail unexpectedly in service. Therefore, a more accurate method for assessing the structural integrity of wooden poles is required. The underlying physical principles behind the 'pole tester's approach' have been identified and used in the development of a decay meter to enable objective monitoring of decay in wooden poles

A survey on cyber security for smart grid communications

A smart grid is a new form of electricity network with high fidelity power-flow control, self-healing, and energy reliability and energy security using digital communications and control technology. To upgrade an existing power grid into a smart grid, it requires significant dependence on intelligent and secure communication infrastructures. It requires security frameworks for distributed communications, pervasive computing and sensing technologies in smart grid. However, as many of the communication technologies currently recommended to use by a smart grid is vulnerable in cyber security, it could lead to unreliable system operations, causing unnecessary expenditure, even consequential disaster to both utilities and consumers. In this paper, we summarize the cyber security requirements and the possible vulnerabilities in smart grid communications and survey the current solutions on cyber security for smart grid communications. © 2012 IEEE

Wireless communication, identification and sensing technologies enabling integrated logistics: a study in the harbor environment

In the last decade, integrated logistics has become an important challenge in the development of wireless communication, identification and sensing technology, due to the growing complexity of logistics processes and the increasing demand for adapting systems to new requirements. The advancement of wireless technology provides a wide range of options for the maritime container terminals. Electronic devices employed in container terminals reduce the manual effort, facilitating timely information flow and enhancing control and quality of service and decision made. In this paper, we examine the technology that can be used to support integration in harbor's logistics. In the literature, most systems have been developed to address specific needs of particular harbors, but a systematic study is missing. The purpose is to provide an overview to the reader about which technology of integrated logistics can be implemented and what remains to be addressed in the future

Competition in Industries Recently Deregulated in Japan

Deregulation in Japan has been caused by both external and internal factors. External factors include requests by the United States and the European Community, where deregulation measures were extensively implemented in order to facilitate these countries\u27 enterprises access into Japan\u27s market. Internal factors include the necessity for the privatization of state or public corporations in order to utilize private initiative to its fullest extent and for the reduction of differences between domestic and international prices

"The global telecommunications infrastructure: European Community (Union) telecommunications developments"

[From the Introduction]. Information, electronics, and telecommunication technologies promise to create communications networks of greatly expanded capacity capable of moving messages across interconnected wired and wireless systems almost anywhere in the world. Such global systems will profoundly affect the economic and social life of all countries. For those countries and economic sectors with a history of significant involvement in electronics, computers, multimedia, and telecommunications, early and timely deployment of state-of-the-art infrastructure may be a matter of prime importance. Many individual countries have made or are making changes intended to accelerate movement toward an information society, in large part because they recognize that a strategic competitive edge in the world economy will likely depend increasingly upon the availability, use, and exploitation of information. A major participant in the information race is the European Union (EU), formerly the European Community. The Commission of the European Union (Commission) has launched a strong push to adopt a common strategy for the creation of a European information society driven by a European information infrastructure. This strategy is aimed at bridging individual initiatives being pursued by EU Member States. [1. Member States now in the Union include the following: Belgium, Denmark, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Portugal, Spain, and the United Kingdom, Austria, Finland and Sweden joined the Union on January 1, 1995.1

Revisiting network neutrality

The paper discusses the topical subject of network neutrality, from a US and European legal perspective. The article will begin by first defining network neutrality before addressing the underpinning technology and will then compare the legal approaches adopted by Europe and the US. In Europe, there is an existing electronic communications regulatory framework which can be used to address the network neutrality problem rendering any further legislation unnecessary and perhaps, detrimental to the current framework. In the US, however, the main concern arising is a potential for a 'fragmented' internet, which leads to our conclusion that network neutrality legislation is necessary on multiple levels. The article will conclude that the US' stance on network neutrality legislation will cause a seismic shift in the way we view technology and the way that networks are accessed and utilised
