Concern regarding extensive damage to tropical forests resulting from logging increased dramatically after World War II when mechanized logging systems developed in industrialized countries were deployed in the tropics. As a consequence, tropical foresters began developing logging procedures that were more environmentally benign, and by the 1990s, these practices began to be described as “reduc...

To illustrate the Reactor pattern, consider the event-driven server for a distributed logging service shown in Figure 1. Client applications use this service to log information (such as error notifications, debugging traces, and status updates) in a distributed environment. In this service, logging records are sent to a central logging server. The logging server outputs the logging records to a...

Abstract Mechanical properties of petroleum reservoirs can be determined via static techniques based on laboratory triaxial tests under reservoir conditions. Dynamic approaches represent an alternative in cases where such data are unavailable. elastic calculated using ultrasonic wave measurements the or situ well logging. Different relationships have been proposed to estimate from dynamic ones ...

Rock sample recognition plays an important role in oil and gas exploration mineral resources exploration. At present, the main rock identification methods are logging, seismic, gravity magnetism, geochemistry, hand samples thin slice analysis so on. In particular, mainstream section requires professionals to analyze slices manually, but manual detection preparation of take a long time. order re...

Pore pressure can be obtained from seismic interval velocity by the to pore transform technique. In this paper, authors present Eaton experimental method calculate for some wellbores in Cuu Long and Song Hong basins, where complex processes of subsidence, burial, geological transformation, geothermal activity took place, causing abnormal zones.The results show that pressures calculated data are...

A new type of logs, the command log, is being employed to replace the traditional data log (e.g., ARIES log) in the inmemory databases. Instead of recording how the tuples are updated, a command log only tracks the transactions being executed, thereby effectively reducing the size of the log and improving the performance. Command logging on the other hand increases the cost of recovery, because...
