Basic features of EJB3 and Spring Framework used for business component management are outlined. The results of frameworks investigation and evaluation are considered. For this purpose 13 criteria have been selected. Offered criteria allow selecting an appropriate framework for...

The work deals with a problem of estimation of spring stiffness under conditions of uncertainty of its loading and compression measurements. During spring exploitation, the main its parameters stiffness and initial length change since of the metal strain aging. At the spring checking, values of its compression are measured in the necessary range of loading. It is used to describe the spring com...

Phenological shifts in events such as flowering and bud break are important indicators of ecosystem processes, and are therefore of particular significance for carbon (C) cycle research. Using long-term flux data from three contrasting plant functional type (evergreen and deciduous) boreal forest sites, we evaluated and compared the responses of annual C fluxes to multiple spring phenological i...

SPRING 2000 THE JOURNAL OF DERIVATIVES 1 Option prices can reveal implied (risk-neutral) distributions, but it is not clear whether these are useful for forecasting or hedging or for revealing the current sentiment of investors. The authors estimate the implied distribution for stock index options in London as a mixture of two lognormals over the period 1987-1997 and find that this method is mu...

This work investigates the practical issue of mapping existing GIS to the OpenGIS standards. We describe the data models used in three systems (MGE, ARC/INFO and SPRING) and analyse the problems involved when mapping them to OpenGIS. Our conclusion is that the OpenGIS standard has not been defined in a formal and unequivocal way, and therefore, there are indefinitions and competing alternatives...

Other local treatments were stopped before the maggots were applied. Systemic antibiotic treatment was stopped as well (except in cases of infection of the navicular bursa.) Between 300 and 900 maggots were used for each wound, depending on its size. They were left in place for three days. In 5 cases the response to the initial MDT was inadequate and so a second treatment was applied for a furt...
