Moving Edge-Side Includes to the Real Edge - the Clients

چکیده
Edge-Side Includes (ESI) is an open mark-up language that allows content providers to break their pages into fragments with individual caching characteristics. A page is reassembled from ESI fragments by a content delivery network (CDN) at an edge server, which selectively downloads from the origin content server only those fragments that are necessary (as opposed to the entire page). This is expected to reduce the load and bandwidth requirements of the content server. This paper proposes an ESI-compliant approach in which page reconstruction occurs at the browser rather than the CDN. Unlike page assembly at the network edge, CSI optimizes content delivery over the last mile, which is where the true bottleneck often is. We call the client-based approach Client-Side Includes, or CSI.

Edge detection in gravity field of the Gheshm sedimentary basin
Edge detection and edge enhancement techniques play an essential role in interpreting potential field data. This paper describes the application of various edge detection techniques to gravity data in order to delineate the edges of subsurface structures. The edge detection methods comprise analytic signal, total horizontal derivative (THDR), theta angle, tilt angle, hyperbolic of tilt angle (H...
متن کاملIn-Plane Analysis of an FGP Plane Weakened by Multiple Moving Cracks
In this paper, the analytical solution of an electric and Volterra edge dislocation in a functionally graded piezoelectric (FGP) medium is obtained by means of complex Fourier transform. The system is subjected to in-plane mechanical and electrical loading. The material properties of the medium vary exponentially with coordinating parallel to the crack. In this study, the rate of the gradual ch...
متن کاملInfluence of Non-Uniform Wall Temperature on Local Heat Transfer Coefficient in a Rotating Square Channel
Abstract: This paper presents the results of an experimental examination of the effect of non-uniform wall temperature on local heat transfer coefficient in a rotating smooth-walled square channel. Three different thermal boundary situations were investigated: (a) even and odd (four) wall uniform temperature, (b) even and odd (four) wall uniform heat flux, and (c) even (leading and trailing) w...
متن کاملCarbon K edge structures of molecular crystals from first-principles: A comparison between phenanthrene and anthracene
By means of ab-initio calculations on the basis of the FPLAPW method, we compared the energy loss near edge structure (ELNES) of carbon K edges in crystalline phenanthrene and its isomer, anthracene. In these two organic compounds, different non-equivalent carbon atoms can result in distinct K edge spectra due to the different carbon-carbon bond lengths, as a characteristic behavior of the mole...

Let D be a digraph with vertex set V(D) .For vertex v V(D), the degree of v, denoted by d(v), is defined as the minimum value if its out-degree and its in-degree . Now let D be a digraph with minimum degree and edge-connectivity If is real number, then the zeroth-order general Randic index is defined by . A digraph is maximally edge-connected if . In this paper we present sufficient condi...
