Logistic constraints and difficulties, as well as risks and economical impact of the bathymetric measurement activity, especially in shallow water, are known matters. This activity, in fact, normally implies the presence of human conductors and operators aboard motorized craft that often have to be transported in difficult to reach places or, even worse, have to operate in sites which are dange...

We have implemented, using Craft (the Cray MPP data parallel language) and HPF 1.1, three basic scientific codes and kernels: a weather forecast program from NCAR, a tensor product, a Monte Carlo application. We compare the performance of the HPF programs to their Craft and message passing versions. Then, we discuss the pros and cons of the data parallel compilers we used and HPF data parallel ...

Surface-Piercing Propellers (SPPs) have been widely used in high speed craft due to some desirable features such as high efficiency, omission of resistance of equipment attached to the propeller and proper functioning of cavitation. Unlike the submerged propellers, theoretical methods have no significant application on simulation of SPPsbecause of problems related to modeling of these propeller...

In this article, the historical use of crafts in occupational therapy for the physically disabled patient is reviewed and the results of a survey aimed at describing current craft use is presented. A questionnaire was sent to a random sample of 250 occupational therapists throughout the United States who chose physical disabilities as their specialty section. Results demonstrated that, while mo...
