Stackable file systems can provide extensible file system functionality with minimal performance overhead and development cost. However, previous approaches are limited in the functionality they provide. In particular, they do not support size-changing algorithms, which are important and useful for many applications, such as compression and security. We propose fast index files, a technique for...

The Particle Flow Analysis (PFA) is currently under intense studies as the most promising way to achieve precision jet energy measurements required at the future linear ee collider. In order to optimize detector configurations and to tune up the PFA it is crucial to identify factors that limit the PFA performance and clarify the fundamental limits on the jet energy resolution that remain even w...

given the importance of sustainable agricultural development, using non-chemical weed management such as cover crops and decreasing row spacing has an importance in weed control and reducing herbicide use. in order to an experiment was conducted at agricultural research site in agricultural college, university of mohaghegh ardabili in 2011. the experiment done as factorial based on randomized c...

urbanisation is still one of the social themes in developing countries. in china, the rapid process of urbanisation and economic growth bring to people not only more opportunities for creating new life and pursuing happiness, but also the challenge to face various and complex social, economical and environmental problems. among them some are outstanding, like the shrinking plowland devoured by ...

This study presents a new approach for physical and material modeling of space frame-raft-soil system. The physical modeling consists of a modified Thimoshenko beam bending element with six degrees of freedom per node to model the beams and columns of the superstructure, a modified Mindlin's plate bending element with five degrees of freedom per node to represent the structural slabs and raft, ...
