given the potential for carbon storage in plant tissues, this approach has a serious interest in recent decades. therefore, the ability of carbon storage in astragalus gossypinus and astragalus parrowianus were examined in part of alpine pastures in kermanshah province. after determining the representative districts, according to 4 main aspect and 5 category elevation was determined representat...

Fibre Channel Over TCP/IP (FCIP) describes mechanisms that allow the interconnection of islands of Fibre Channel storage area networks over IP-based networks to form a unified storage area network in a single Fibre Channel fabric. FCIP relies on IP-based network services to provide the connectivity between the storage area network islands over local area networks, metropolitan area networks, or...

Deduplication is now widely accepted as an efficient technique for reducing storage costs at the expense of some processing overhead, being increasingly sought in primary storage systems [7, 8] and cloud computing infrastructures holding Virtual Machine (VM) volumes [2, 1, 5]. Besides a large number of duplicates that can be found across static VM images [3], dynamic general purpose data from V...

Large multidimensional datasets are found in diverse application areas, such as data warehousing [6], satellite data processing, and high-energy physics [9]. According to current estimates, these datasets are expected to hold terabytes of data. Since these datasets hold mainly historical and aggregate data, their sizes are increasing. Daily accumulation of raw data and jobs generating aggregate...

When planning a wireless local area network, there are design issues that need to be considered. In this paper, the fundamentals of planning a wireless local area network are introduced and discussed to highlight the requirements involved. Network constraints, as encountered in the physical environment, are discussed and their relevance to wireless network design is investigated. The paper conc...

Wireless Local Area Networks (WLANs) are subjected to interference because of their working in Unlicensed Spectrum. Coverage ranges of WLANs are 30 to 300m. Channel Assignment is one of the most important problems in the WLANs. In this paper we present a Survey on the Channel Assignment techniques in IEEE 802.11.After analyzing different methods a qualitative comparison has been carried out for...

This paper evaluates the Total Vector Error of an estimated Phasor as define in IEEE C37.118 standard within different medium access in Local Area Networks (LAN). Three different LAN models (CSMA/CD, CSMA/AMP and Switched Ethernet) are evaluated. The Total Vector Error of the estimated Phasor has been evaluated for the effect of Nodes Number under the standardized network Band-width values defi...

This paper discusses the state of the art in networking, and explains the way existing networks can support tele-education applications. Chapter 1 identifies which tele-education parameters have the biggest impact upon the underlying network, and proposes a classification of teleeducation applications. Chapter 2 discusses the various networks that are used for tele-education purposes: Local Are...

The intent of this functional research project is to apply the tools of Trade Area Analysis (TAA) to retail and service sales data for Wisconsin Counties. For this analysis we use the sales tax data as reported by the Wisconsin Department of Revenue for 2004, the most current year the data are available. Only those counties that have elected to collect the optional county sales tax are included...
