Logging has been a common practice for monitoring and diagnosing performance issues. However, logging comes at a cost, especially for large-scale online service systems. First, the overhead incurred by intensive logging is non-negligible. Second, it is costly to diagnose a performance issue if there are a tremendous amount of redundant logs. Therefore, we believe that it is important to limit t...

[1] In this study, we used porosity to assess the compaction state of the Nankai accretionary wedge sediments and any implications for stress and pore pressure. However, hydrous minerals affect porosity measurements, and accounting for them is essential toward defining the interstitial porosity truly representative of the compaction state. The water content of sediments was measured in core sam...

 The portable digital multimeters (DMMs) frequently recommended to be used for data acquisition from electromagnetic field meters are the data logging DMMs. In this paper it is shown that it is better to use for this task the DMMs with event logging mode instead of the ones with the data logging mode. The advantages obtained using these DMMs are presented. The performed experimental results pr...

Production variability is a significant determinant of logging investment outcome. This variability may result from either process variation or zero production weeks. Using assumptions for a “typical” Southern logging system, the Auburn Harvest Analyzer and a simulation model, the impacts of production variation on logging cost, investment return and risk were estimated. The expected value of l...

Off-line intrusion detection systems rely on logged data. However, the logging mechanism may be complicated and time-consuming and the amount of logged data tends to be very large. To counter these problems we suggest a very simple and cheap logging method, light-weight logging. It can be easily implemented on a Unix system, particularly on the Solaris operating system from Sun. It is based on ...

Long-term changes (-20 years) in water yield, the storm hydrograph, stream inorganic chemistry, and sediment yield were analyzed for a 59 ha mixed hardwood covered catchment (Watershed 7) in the southern Appalachian mountains (USA) following clearcutting and cable logging. The first year after cutting, streamflow increased 26 cm or 28% above the flow expected if the forest had not been cut. In ...

Langgu Depression is a mature oil and gas exploration area with complicated lithological physical properties. The varying formation fluid, low-resistivity hydrocarbon-bearing reservoirs, non-uniform logging series greatly increase the difficulty of reservoir identification. Monte Carlo method employed to simulate neutron–gamma responses saturation influential factors. According result, new iden...

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...

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...
