It is well known that a large proportion of available logging residues intended for extraction will not reach the energy-conversion industry, because some are lost during transportation or left on the clear-felled area. However, there is little understanding of where logging residue losses occur in the supply chain. In this study, the distribution of logging residues for two methods (driedand f...

Message logging has long been advocated as offering better failure-free performance than coordinated checkpointing. On the contrary, we present a number of experiments showing that for compute-intensive applications executing in parallel on clusters of workstations, message logging has higher failure-free overhead than coordinated checkpointing. Message logging protocols, however, result in muc...

Checkpointing and logging are widely used techniques to provide fault tolerance for the distributed systems. However, logging imposes too much overhead on the processing to be a practi-val solution. In this paper, we propose a low-overhead logging scheme for the distributed shared memory system based on the lazy release consistency model. Unlike the previous schemes in which the logging is perf...

Selective logging may impact patterns of genetic diversity within populations of harvested forest tree species by increasing distances separating conspecific trees, and modifying physical and biotic features of the forest habitat. We measured levels of gene diversity, inbreeding, pollen dispersal and spatial genetic structure (SGS) of an Amazonian insect-pollinated Carapa guianensis population ...

Nuclear magnetic resonance (NMR) relaxometry and diffusometry are important tools for the characterization of heterogeneous materials and porous media, with applications including medical imaging, food characterization and oil-well logging. These methods can be extremely effective in applications where high-resolution NMR is either unnecessary, impractical, or both, as is the case in the emergi...

Ecological communities including tropical rainforest are rapidly changing under various disturbances caused by increasing human activities. Recently in Cambodia, illegal logging and clear-felling for agriculture have been increasing. Here, we study the effects of logging, mortality and recruitment of plot trees on phylogenetic community structure in 32 plots in Kampong Thom, Cambodia. Each plot...

DORI (Distributed Outdoor Robotic Instruments) is a remotely controlled vehicle that is designed to simulate a planetary exploration mission. DORI is equipped with over 20 environmental sensors and can perform basic data analysis, logging and remote upload. The individual components are distributed across a fault-tolerant bus for redundancy. A partial sensor list includes atmospheric pressure, ...

The World Bank estimates the value of the global illegal timber trade at more than $10 billion per year. Tracking the timber supply chain is poor and allows widespread illegal logging, log smuggling and log laundering, it believes. Timber taken from remote forests in Asia, Russia, South America and Africa is often shipped long distances and its only certification is a paper trail that is highly...
