The geographies of cyberspace

In this I paper I explore the need for a new field of geographic enquiry called cybergeography. This is the investigation of the complex and multifaceted structure, use and experience of the online world inside global computer-communications networks, most obviously represented by the Internet and the World-Wide Web. In particular I focus on how one can study the geography of Internet diffusion from publicly available statistics. Then I consider ways that the landscapes of Cyberspace can be mapped to enhance our understanding of their evolving form and texture using examples of a real-time “weather map” of Internet congestion and maps of the urban structure of virtual world

Computer program determines vibration in three-dimensional space of hydraulic lines excited by forced displacements

Computer program determines the forced vibration in three dimensional space of a multiple degree of freedom beam type structural system. Provision is made for the longitudinal axis of the analytical model to change orientation at any point along its length. This program is used by industries in which structural design dynamic analyses are performed

The determination of the extent to which reading reinforced by hearing shows a gain in comprehension in comparison with reading alone when comparable materials are used.

Economic considerations of utilizing small wind generators

The economic feasibility of small wind generators is compared to that of solar cells, primary batteries, thermoelectric generators, and engine generators. It is shown that small wind generator plants offer an attractive alternative to primary battery systems and constantly running engines to generate power in remote areas. The limitation is an annual average wind velocity of at least 9 to 10 mph. Presently available units are most useful in the average load range of 10 to 1000 watts
