Underwater bottom topography may be visible on Synthetic Aperture Radar (SAR) images through the radar signature of ocean surface currents. Using SAR images and a limited number of echo soundings it is possible to constructs accurate depth maps, greatly reducing the costs of bathymetric surveying. Based on shallow water bathymetry synthetic aperture radar (SAR) imaging mechanism and the microwa...

A shallow depth-of-field is often used as a creative element in photographs. This, however, comes at the cost of expensive and heavy camera equipment, such as large sensor DSLR bodies and fast lenses. In contrast, cheap small-sensor cameras with fixed lenses usually exhibit a larger depth-of-field than desirable. In this case a computational solution is suggesting, since a shallow depth-of-fiel...

This paper reports the results of an exploratory study that investigated expert and novice debugging processes with the aim of contributing to a general theory of programming expertise. The method used was verbal protocol analysis. Data was collected from 16 programmers employed by the same organization. First, an expert-novice classification of subjects was derived from information based on su...

Impact of the satellite data assimilation on the naval undersea capability is investigated using the ocean hydrographic data without and with satellite data assimilation. The former is the Navy’s Global Digital Environmental Model (GDEM) providing the monthly mean; and the latter is the Modular Ocean Data Assimilation System (MODAS) proving the synoptic data. The two environmental datasets are ...

High speed and absence of a precise control over pressure distribution confine sheet Electromagnetic Forming into a die to simple shapes having shallow depth. It is possible to reach a higher depth by using a convex punch instead of a concave die. In this study, sheet Electromagnetic Forming on a punch and sheet Electromagnetic Forming into a die are investigated. The electromagnetic part of th...

Most studies on coral reefs have focused on shallow reef (< 30 m) systems due to the technical limitations of conducting scientific diving deeper than 30 m. Compared to their shallow-water counterparts, these mesophotic coral reefs (30-150 m) are understudied, which has slowed our broader understanding of the biodiversity, ecology, and connectivity of shallow and deep coral reef communities. We...

an appropriate method to determine the hydraulic conductivity above water table is guelph permeameter. using this method, experiments can be carried out by one person in a short period. several investigators have commented on the systematic difference between the hydraulic conductivity obtained by guelph permeameter and shallow well pumping test (swpt) methods. therefore, the purpose of this re...
