The grain size composition of topsoil characterizes the soil texture and other physical properties. The coarsening of topsoil grain size is a visible symbol of land degradation; thereby the change in topsoil grain size can be potentially used to monitor desertification using remote sensing. This study proposes a new index for detecting topsoil grain size composition through ground in situ soil ...

one of the most common methods for production of ultra fine grained materials is severe plastic deformation (spd). in this study, constrained groove pressing (cgp) and high pressure torsion (hpt) processes as effective methods of severe plastic deformation for the strain imposed on the pure copper were used. this paper presents the results of an experimental research, to review the influence of...

Skew is one of the most important parameter that decides the performance of the system. Though skews are reduced using two-stage(low and high voltage levels) serially connected power mode aware buffers(PMABs) using two power gating techniques-Fine grain technique at high voltage level and Coarse grain technique at low voltage level, the power consumption and area is large incase of fine grain t...

In this paper we present VirtuosoNext, an RTOS for distributed heterogeneous systems which provides fine-grain space and time partitioning. Focusing on the Space Partitioning, the benefits and penalties of fine-grain space partitioning for real-time systems are presented by comparing VirtuosoNext to its predecessor OpenComRTOS-1.6. Both use a static memory model and can be used simultanueously ...

This paper discusses the issues involved in implementing a dynamic programming algorithm for biological sequence comparison on a general-purpose parallel computing platform based on a fine-grain event-driven multithreaded program execution model. Fine-grain multithreading permits efficient parallelism exploitation in this application both by taking advantage of asynchronous point-to-point synch...

The physics motivations for a fine grain 1st level electron/photon trigger which exploits the properties of the CMS crystal calorimeter are briefly introduced. An implementation architecture that extends the present design of the CMS calorimeter trigger is described. We then discuss the characteristics and the requirements of the electronic circuits needed to implement the fine grained trigger ...

To assign semantic roles in building Treebanks, there is a need for annotators having a guideline in determining semantic relations between phrasal head and its modifiers or arguments. Semantic roles are hard to have clear-cut definitions. It is not always easy to determine thematic relations between two concepts. This paper aims to introduce an integrated nominal modifier system. Basically we ...

In this work, the evolution of microstructure and the thermo-mechanical behavior of co pper and dilute copper alloy thin films was investigated. 0.3 to 2.0 μm thick film s were deposited by magnetron sputtering under ultra high vacuum conditions onto diffusion-barrier coated silicon substrates and subjected to wafer curvature measurements. Pure copper films annealed in ultra high vacuum exhibit...
