In the current era of cloud computing, data stored in the cloud is being generated at a tremendous speed, and thus the cloud storage system has become one of the key components in cloud computing. By storing a substantial amount of data in commodity disks inside the data center that hosts the cloud, the cloud storage system must consider one question very carefully: how do we store data reliabl...

In this paper, we aim at developing a model for option pricing to reduce the risks associated with Ethiopian commodity prices fluctuations. We used the daily closed Unwashed Lekempti grade 5 (ULK5) coffee and Whitish Wollega Sesame Seed Grade3 (WWSS3) prices obtained from Ethiopia commodity exchange (ECX) market to analyse the prices fluctuations.The natures of log-returns of the prices exhibit a...

The article is devoted to the analysis of semantics and features functioning textual bond "bolee togo" [moreover]. aim work was identify specifics this bond, taking into account its semantic in texts various functional styles genres. Moreover, following research methods have been applied comprehend bond: traditional descriptive method, including observation, generalization systematization lingu...

Since China has been Iran's most important trading partner in recent years, the present study has attempted to investigate the effect of bilateral real exchange rate fluctuations on the trade relationship between Iran and China during the period 1992-2017. To investigate this relationship, the business data in the export and import sectors were divided into 15 major commodity segments, and the ...

A fast method to generate fractal imagery is presented. Iterated Function Systems (IFS) are based on repeatedly copying transformed images. We show that this can be directly translated into standard graphics operations: Each image is generated by texture mapping and blending copies of the previous image. Animations of dynamic IFS codes are generated at fifty frames per second on a notebook PC, ...

Commodity clusters revolutionized high performance computing in a fundamental way since its first inception, and now now dominate many of the world’s premiere supercomputers on the Top500, growing to the scale of over 10,000 CPU cores and beyond. Still,"classical" specialized vector supercomputers still remain to be sold and facilitated, especially at high end of the market, largely due to the ...

We explore the feasibility of implementing a reliable, high performance, distributed storage system on a commodity computing cluster. Files are distributed across storage nodes using erasure coding with small Low-Density Parity-Check (LDPC) codes, which provide highreliability with small storage and performance overhead. We present performance measurements done on a prototype system comprising ...

it is a well-known result in both environmental economics and natural resources managementthat you will not be able to manage what you are not able to measure. this paper presents a dichotomous-choicecontingent valuation survey that analyses individuals’ preferences for the implementation of a rural developmentprogram (rdp) that fosters the provision of non-commodity outputs in rural areas in s...
