Dynamic hydroelastic centrifugal couplings

The operational principle of dynamic hydroelastic centrifugal couplings is discussed in this paper. An experimental setup for testing dynamical characteristics of the coupling is developed, dynamical properties of the coupling are tested. It is shown that hydroelastic elements can considerably improve operational characteristics of the coupling, especially if transmitted vibrations are to be dampe

Telecommunications Access in the Age of Electronic Commerce: Toward a Third-Generation Universal Service Policy

Like many other countries, the United States is in the midst of redefining its universal service policy. Access to telecommunications no longer depends on connecting a copper wire line into the home. Rather, universal service depends on how people will access and use the infrastructure around them. The ability to access communications facilities requires an account relationship between the supplier and the user. Therefore, the account relationship, not the presence of a physical connection to the home, should be the focal point of a universal service policy. With the rise of electronic commerce, access hinges on account verification, credit authorizations, billings, and collection. Metaphorically, the symbol for the third generation of universal service is not the wire, but the card, be it the credit card, the debit card, or the SIM card

The Evolution of Financial Instruments and the Legal Protection Against Counterfeiting: A Look at Coin, Paper, and Virtual Currencies

This essay discusses the requirements for the long-term acceptance of virtual currency as a financial medium of exchange by examination of fundamental criteria associated with the historical development of common tender and selected virtual currencies. The relatively recent appearance of Internet-based transactions have necessitated developing virtual forms of payment such as virtual currencies. According to the Financial Crimes Enforcement Network (“FinCEN”) of the United States Treasury,5 virtual currencies are subject to regulation if that virtual currency has a substitutive purpose for facilitating the exchange of goods and services. Although governments can place stipulations on currencies, users of common tender, including virtual currencies, expect at least three basic privileges for a virtual currency to evolve from conception to realization. First, a virtual currency must be considered intangible personal property similar to trademarks, copyrights, and patents. Second, ownership disputes must be subject to a system such as a judicial proceeding or binding arbitration to resolve property as well as interest conflicts. Finally, a virtual currency must be subject to similar regulation as other financial instruments (e.g., legal tender, scrip, and credit cards) used in facilitating transactions. One of the most common and critical aspects of safeguarding currency is protection against illegitimate representations of assets—that is, primarily against counterfeiting. We discuss the regulatory authority and/or lack of authority, of the sovereign States of the United States to regulate the counterfeiting of financial instruments used as currency, including virtual currency. Moreover, federal and foreign (non-U.S.) currencies are explicitly examined, but some virtual currencies are not regulated or authorized specifically by any government. Can a currency without formal codification from a government be regulated by a sovereign State? As financial transactions have shifted historically from various governments’ legal tender to combinations of government and private issuances and from the hard currency of coins and paper to electronic transactions, many States’ counterfeiting statutes are unclear or fail to consider that technological changes can impact legal and common tender. The rise of transactions facilitated by virtual currencies and regulations protecting states from virtual counterfeiting is examined and discussed

Assessment of plastics in the National Trust: a case study at Mr Straw's House

The National Trust is a charity that cares for over 300 publically accessible historic buildings and their contents across England, Wales and Northern Ireland. There have been few previous studies on preservation of plastics within National Trust collections, which form a significant part of the more modern collections of objects. This paper describes the design of an assessment system which was successfully trialled at Mr Straws House, a National Trust property in Worksop, UK. This system can now be used for future plastic surveys at other National Trust properties. In addition, the survey gave valuable information about the state of the collection, demonstrating that the plastics that are deteriorating are those that are known to be vulnerable, namely cellulose nitrate/acetate, PVC and rubber. Verifying this knowledge of the most vulnerable plastics enables us to recommend to properties across National Trust that these types should be seen as a priority for correct storage and in-depth recording
