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 ...

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...

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...

Physical Layer Detection of Hardware Keyloggers

The development of satellite-derived datasets has greatly facilitated large-scale ecological studies, as in situ observations are spatially sparse and expensive undertakings. We tested the efficacy of using satellite sea surface temperature (SST) collected by NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) and local water temperature collected from NOAA buoys and onshore stations t...

Logging is a particular storage semantic involving speciic storage mechanisms, e.g. nding the log end or sequencing through a log. This paper presents the main logging techniques issues through a study of four existing logging systems implemented as independent storage systems: Clio, Camelot DLF, Ki t L o g and Sprite LFS. It aims to provide a clear view of problems and actual solutions.

Logging contract systems are in need of change—they are leading to environmentally destructive exploitation and poor returns to landowners. The reaction has been to ban logging, thus giving subsidies to domestic timber processing industries. Export taxes are an inefficient and inequitable means of timber revenue distribution. The logging contract needs to be changed to allow landowners and gove...
