Petrophysical evaluation of petroleum reservoirs is one of the most challenging tasks for hydrocarbon reserve determination. One critical petrophysical parameter is the water saturation which is normally calculated from Archie’s equation. Carbonate reservoirs, however, due to their complex mineralogy are not good candidates for Archie’s equation because Archie’s parameters are strongly dependen...

Emerging byte-addressable, non-volatile memory technologies (NVRAM) like phase-change memory can increase the capacity of future memory systems by orders of magnitude. Compared to systems that rely on disk storage, NVRAMbased systems promise significant improvements in performance for key applications like online transaction processing (OLTP). Unfortunately, NVRAM systems suffer from two drawba...

Nowadays, due to the increased user requirements of the fast and reliable data management operation for mobile applications, major device vendors use embedded DBMS for their mobile devices such as MP3 players, mobile phones, digital cameras and PDAs. However, database logging is the major bottleneck against the fast response time. There has been a lot of work minimizing logging overhead but no ...

INTRODUCTION The effect of logging on spotted owls (Strix occidentalis) and their habitat has been one of the most pressing wildlife conservation questions facing western forest managers for the past 30 years. Two subspecies, the northern and Mexican spotted owls (S. o. caurina and S. o. lucida, respectively), have been listed as threatened, in part, based on the loss of habitat due to logging ...

In the existing Fault-Tolerant Software Distributed Shared Memory (FT-SDSM) with the message logging, the logs are used only to recover the failed nodes. In our previous work, we have implemented a lightweight logging protocol, called remote logging, on the SDSM for fault tolerance, which incurs low logging overhead with a fast network and a remote memory for back-up data. In this paper, we pro...

Information on the productivity, costs and applications of the logging system is a key component in the evaluation of management plans for the rehabilitation and utilization of Caspian forests. Skidding and road construction costs are expensive forest operations. Determining the optimum forest road network density is one of the most important factors in sustainable forest management. Logging me...

Economic and environmental logging is important for sustainable wood production in the Caspian forests, north of Iran. Predetermination of the skid trail network and directional felling is a usual recommended method to reduce logging impact. The aim of this study was evaluation of directional felling and finding factors effective on felling error. Totally 135 trees were selected randomly for di...
