An analytical approach is presented to assess the response of offshore structures under seismic excitation. This paper evaluates the impacts of different fluid field models and the mass of equipment at the top of offshore structure which is simulated as lumped mass on the responses of offshore structures. To do this, two and three dimensional fluid field models are developed. In three dimension...

The International Forum on Translation Technology will be held on the theme of cooperative work between humans and the computer. As an example of the cooperative work, the present situation and prospects for the machine translation value-added network (MT-VAN) service will be described below. In the MT-VAN, users, the machine translation systems and the translators are satisfactory linked by th...

Abstract Falling coffee filters are a common object of study in introductory physics laboratory classes. They usually used to demonstrate the terminal velocity, and determine how drag force depends on this velocity. However they can also be other ways that air affects motion falling filter. In particular, qualitatively different fluid acts during initial acceleration from rest, causes much less...

Businesses that rely on a value-added network to provide information processing and communications services are only as secure as the network itself. The customer should understand the types of processing and control services provided by such vendors, and the potential exposures that use of these networks can entail. This article describes the control issues that must be addressed, the controls...
