This letter introduces a buffer management issue in designing SSDs for log-structured file systems (LFSs). We implemented a novel trace-driven SSD simulator in SystemC language, and simulated several SSD architectures with the NILFS2 trace. From the results, we give two major considerations related to the buffer management as follows. (1) The write buffer is used as a buffer not a cache, since ...

The reality of protected area management is that enforcing forest and park boundaries is costly and so most likely incomplete, due in part to the pressures exerted on the boundaries by local people who often have traditionally relied on the park resources. Buffer zones are increasingly being proposed and implemented to protect both forest resources and livelihoods. Developing a spatially-explic...

The purpose of this work is to assess the effectiveness of two grass covers (buffer zone and grass-covered inter-row), to reduce pesticide leaching, and subsequently to preserve groundwater quality. Lower amounts of pesticides leached through grass-cover soil columns (2.7-24.3% of the initial amount) than the bare soil columns (8.0-55.1%), in correspondence with their sorption coefficients. Diu...

In plants, growth of roots and root hairs is regulated by the fine cellular control of pH and reactive oxygen species (ROS). MES, 2-(N-morpholino)ethanesulfonic acid as one of the Good's buffers has broadly been used for buffering medium, and it is thought to suit for plant growth with the concentration at 0.1% (w/v) because the buffer capacity of MES ranging pH 5.5-7.0 (for Arabidopsis, pH 5.8...

The stream buffer is the region immediately be yond the banks of a stream that serves to limit the entrance of sediment, pollutants, and nutrients to the stream itself. When forested, a stream buffer promotes bank stability and serves as a major control of water temperature (Leopold, 1997). From a biological perspective, the importance of a healthy, intact riparian zone has only been understood...

Three major issues associated with numerical simulations of complex free-surface flows, viz. interface tracking, fragmentation and large physical jumps, are addressed by a new Hybrid continuum-particle model (HyPAM). The new model consists of three parts: (1) the Polygonal Area Mapping method [Q. Zhang and P. L.-F. Liu, A new interface tracking method: The polygonal area mapping method. J. Comp...

Conservation area buffer zones are recognized to provide ecological, social, and economic benefits in supporting conservation areas' integrity. Nevertheless, little is known hitherto about the development dynamics of Indonesia. Therefore, a study concerning theory, policy, management Indonesia necessary analyze its performance, identify problems implementation, formulate evidence-based policy. ...
