PassDB : parser for password dump database
… hackers are finished using the stolen data, they dump it on the internet in so-called data dumps. The project consisted of building a system that can be used to parse passwords and emails from most data dumps given (i.e., data leakage after security breach) and store them in some standard form …

HYDROLOGICAL CHARACTERIZATION OF A SULPHIDE WASTE ROCK DUMP
… drainage (ARD) from sulphide bearing waste rock dumps poses a serious threat to the environment and has become problematic to the mining industry. Water that is discharged from sulphide waste rock dumps has the potential to be low in pH, thus having the ability to transport heavy metals. The acid …

Dredge spoil dispersion from an inner shelf dump-mound
… on the dispersion of dredge spoil from a dump-mound on the inner shelf in 11-17 m water depth, 3 km offshore from Tauranga Harbour, New Zealand. Graphic and volumetric analysis of bathymetric changes over the dump-mound and its near vicinity, between 1978 and 1988, showed that based on …

The characterization of the flowfield of a dump combustor
… flowfield, a water-cooled, stainless steel dump combustor model was developed. A two-component Laser Doppler Anemometer (LOA) was used to measure the mean and turbulent velocities in the axial and tangential directions and provide a comparison between combusting and isothermal flows. …

Search for axion-like particles in the slac beam dump
… the Stanford Linear Accelerator Center (SLAC) by dumping 30 Coulombs of 20 GeV electrons into a beam absorption facility. After 179 meters of earth shielding the in-flight decay of the particle into two photons or an electron-positron pair, in a decay volume of 204 meters in length, was searched …

Mechanics of dump truck vibrations in high-impact shovel loading operations
… (HISLO). In extreme cases, shovels load large dump trucks with 100-ton (or more) passes generating high-impact forces under gravity. HISLO generates high-frequency shockwaves that cause severe truck vibrations exposing operators to whole body vibrations (WBV). This WBV levels may exceed the …

Investigation of liquid fuel jet injection into a simulated subsonic "dump" combustor
… designed to represent a sudden-expansion "dump" combustor were performed under cold-flow conditions. Test conditions were as follows: 0.6 entrance Mach number, 25 PSIA total pressure, and nominally 75°F stagnation temperature. Two step heights were investigated, 1.0 in. and 0.5 in., …

Thermomechanical fatigue life investigation of an ultra-large mining dump truck tire
The cost benefits associated with the use of heavy mining machinery in the surface mining industry has led to a surge in the production of ultra-large radial tires with rim diameters in excess of 35 in. These tires experience fatigue failures in operation. The use of reinforcing fillers and …

A new method for calculating the flow field in a dump combustor
… procedure for solving the flow field in a dump combustor is described. The elliptic calculation is used at the dump combustor entrance and a parabolic calculation downstream. The calculations are restricted to steady axisymmetric nonreactive incompressible flow. A great savings in …

Garbage Dump Expertise : Tracing the 'Common Man' Project in the works of Aditya Prakash
This written work examines the relationship of "the common man" or the citizen, to the city though a historical account of the work of Aditya Prakash - an Indian modernist, who was part of the Capital Project Team -lead by Le Corbusier who designed the city of Chandigarh. The work of Aditya Prakash …

In-situ measurements and calculation of radon gas concentration and exhalation from a tailings mine dump
… bearing tailings are then placed on large dumps which are usually one or more kilometres in diameter in the environment. There are approximately 250 gold mine tailings dumps covering a total area of about 7000 ha. These gold mine tailings dumps contain considerable amounts of radium (226Ra) …

Zooarchaeological analysis of an urban refuse dump in Cape Town's waterside at the turn of the 19th century
… The majority of the cultural material from this dump site dates to between c.1780 and c.1830. This time period covers the ending of the Verenigde Oostindische Companjie's (VOC) occupation of the Cape and its final succession to British rule in 1806. The explicit aim of this study was to go beyond …

Impact of mine pollution of composition, diversity and structure of plant and ground-dwelling invertebrate communities around Kombat mine tailing dump, Namibia
… was investigated at Kombat Mine tailings dump in Namibia. Sixteen transect lines were marked around the dump. Plots, 15m x 15m, were marked at 50m intervals along each transect. Top soils in the demarcated plots were sampled and analysed for concentrations of heavy metals and total …

Multi-body dynamic and finite element modeling of ultra-large dump truck - haul road interactions for machine health and haul road structural integrity
<p>"Haul truck capacities have increased due to their economies of scale in large-scale surface mine production systems. Ultra-large trucks impose high dynamic loads on haul roads. The dynamic loads are exacerbated by road surface roughness and truck over-loading. The dynamic forces also subject …

The application of high temperature superconducting materials to power switches
… in conjunction with a parallel resistor or dump-switches where all of the energy is dissipated in the switch itself. Bypass-switches are more suited to higher energy circuits as a portion of the energy can be dissipated in the external dump resistor. Dump-switches require less material and …
