Over 20% of the world's tropical forests have been selectively logged, and large expanses are allocated for future timber extraction. Reduced-impact logging (RIL) is being promoted as best practice forestry that increases sustainability and lowers CO2 emissions from logging, by reducing collateral damage associated with timber extraction. RIL is also expected to minimize the impacts of selectiv...

This paper presents an innovative solution for estimating the proximate parameters of coal beds from the well-logs. To implement the solution, the C# programming language was used. The data from four exploratory boreholes was used in a case study to express the method and determine its accuracy. Then two boreholes were selected as the reference, namely the boreholes with available well-logging ...

NMR Oil Well Logging: Diffusional Coupling and Internal Gradients in Porous Media

This paper is concerned with an improved network model in acoustical application to petroleum logging and seismic exploration. Utilizing acoustic-electric analogue, we report in this paper a newly developed acoustic-logging network model. Important relationships amongst various physical factors are established, i.e. driving-voltage signal, electric-acoustic conversion of source-transducer, acou...

Event logging on mobile phones is interesting for e.g. diary keeping. We present a logging service which – automatically and in the background on Symbian based mobile phones – logs events originated by user interactivities with mobile phones. Context information that can be obtained by the phones themselves is logged as well. The service offers direct access to the logged events, so that data c...

When systems fail in the field, logged error or warning messages are frequently the only evidence available for assessing and diagnosing the underlying cause. Consequently, the efficacy of such logging—how often and how well error causes can be determined via postmortem log messages—is a matter of significant practical importance. However, there is little empirical data about how well existing ...

In the Brazilian Amazon, multiple logging activities are undergoing, involving different actors and interests. They shape a disturbance gradient bound to the intensity and frequency of logging, and forest management techniques. However, until now, few studies have been carried out at the landscape scale taking into account these multiple types of logging and this disturbance gradient. Here we a...

water logging stress is one of the most important factors which affect wheat production particularly in western regions of golestan province. this experiment was carried out in order to evaluate of six genotypes (n-81-18, arta, moghan, n-80-19, urwyt-82-11 and urwyt-82-17) of bread wheat in water logging condition at 2006-2007 growing season in gorgan agricultural research station. the experime...

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...
