A field site was developed in the foothills of the Sierra Nevada, California, to develop and test a multidisciplinary approach to the characterization of ground-water flow and transport in fractured rocks. Nine boreholes were drilled into the granitic bedrock, and a wide variety of instruments and methodologies were tested. Fracture properties were measured on outcrops and in boreholes using ac...

Collapsible soils are unsaturated low-density that undergo abrupt settlement when flooded without any increase in the in-situ stress level. The first stage of site characterization is identifying collapsible soils, since these problematic soils. Seismic cone testing (SCPT) has been increasingly used for characterization, because it allows combining stratigraphic logging with maximum shear modul...

Southern timber harvesting equipment and on-road vehicle costs were obtained for the years from 1967 to 1984. Average cost trends for equipment and vehicles were determined for the period. Average logging contract rates and price trends were also estimated. Comparisons indicated that equipment costs increased more than the general inflation rate and less than the prices of other industrial comm...

Fine structural interpretation is one of the effective methods to find favorable traps and targets. Aiming at fault Jurassic Badaowan Fm in Madong area Xiayan zone not fine characteristics are implemented, implemented found through study seismic, well logging geological comprehensive methods. The results show that structure high north low south. first member a delta front subaqueous distributar...

Cloud computing o ers computational resources such as processing, networking, and storage to customers. Infrastructure as a Service (IaaS) consists of a cloud-based infrastructure to o er consumers raw computation resources such as storage and networking. These resources are billed using a pay-per-use cost model. However, IaaS is far from being a secure cloud infrastructure as the seven main se...

[1] We report on seismic and petrological data that provide new constraints on the geological evolution of the Amerasia Basin. A seismic reflection transect across the Makarov Basin, located between the Mendeleev and Lomonosov Ridges, shows a complete undisturbed sedimentary section of Mesozoic/Cenozoic age. In contrast to the Mendeleev Ridge, the margin of the Lomonosov Ridge is wide and shows...

Coring, geophysical logging, and in-situ temperature measurements were performed with the MARUM-MeBo200 seafloor rig to characterize gas hydrate occurrences in sediments of Danube deep sea fan, off Romania, Black Sea. The new drilling data showed no evidence for significant saturations within but presence free at depth bottom-simulating reflector (BSR). In-situ core-derived geochemical suggest ...

Manetho is a new transparent rollback recovery protocol for long running distributed computations It uses a novel combination of antecedence graph maintenance unco ordinated checkpointing and sender based message logging Manetho simultaneously achieves the advantages of pessimistic message logging namely limited rollback and fast output commit and the advantage of optimistic message logging nam...
