Despite significant efforts to obtain an accurate picture of structure at the level of individual autonomous systems (ASes), much remains unknown in terms of the quality of the inferred AS maps that have been widely used by the research community. Building upon our recent results reported in [16], in this paper we take a first step towards quantifying the (in)completeness of the observed AS-lev...

Presentation conversion is a key operation in any development environment for distributed applications, such as Corba, Java-RMI, DCE or ASN.1-based environments. It is also well-known performance bottleneck in high-speed network communication. Presentation conversion code is usually generated by an automatic code generation tool referred to as stub compiler. The quality of the code generated by...

A stub generator is a tool that automatically produces the communication software required for presentation conversion. An open problem in stub generation is finding the right trade-off between code size and execution speed of the generated code. The generation of tables that are interpreted at run-time leads to small but slow object code. The direct generation of program code leads to fast but...

background: in this study we evaluated the prognostic impact of metastatic lymph node ratio (mlr) in patients with gastric cancer undergoing curative surgical resection. methods: a total of 121 patients with gastric adenocarcinoma undergoing curative r0 surgical resection in our institutions between 2003 and 2010 were included in this study.  mlr was classified into 3 groups as follows: mlr0; 0...

The Border Gateway Protocol (BGP) was designed as a successor to the Exterior Gateway Protocol. BGP started as a subset of the IDRP protocol [ISO93] being developed by ISO. During the last ten years, BGP has evolved in an incremental and backward compatible manner. In the early nineties, the main objective of BGP was to make possible the distribution of routes constrained by routeing policies, ...

A printed Bow-Tie slot antenna with loaded stub is proposed and the effects of changing the dimensions of the slot area, the stub and load sizes are considered in this paper. These parameters have a considerable effect on the antenna characteristics as well as its performance. An in-depth parametric study of these dimensions is presented. This paper proposes the necessary conditions for initial...

A low-profile microstrip planar monopole antenna with triple-band operation for WiMAX and WLAN applications is proposed. The antenna has a simple structure which consists of a rectangular radiation patch with an L-shaped slot and an inverted L-shaped stub extending from the ground plane. By etching an L-shaped slot on the rectangular radiation patch, the antenna can excite two resonant modes. T...

This paper reports a compact bandpass filter with improved skirt selectivity using integrated passive device fabrication technology on a GaAs substrate. The structure of the filter consists of electromagnetically coupled meandered-line symmetric stepped-impedance resonators. The strength of the coupling between the resonators is enhanced by using a meandered-line stub-load inside the resonators...

Given a web service W , a stub is a simple service S intended to impersonate W and simulate some of its input-output patterns. When W ’s behaviour is represented by a logic formula φ, S can use a satisfiability solver to drive the simulation and generate valid messages compliant with φ. A satisfiability solver for a variant of first-order temporal logic, called LTL-FO, is described. Using a cha...

A novel CPW-fed antenna capable of triple-band operation for WLAN/WiMAX applications is presented and investigated in this paper. The proposed antenna simply consists of three elements viz. folded open stub, L-shaped open stub, and Y-shaped resonator. By using the three elements, triple-band antenna operating at 2.5/3.5/5.5 GHz can be achieved. The antenna impedance bandwidths for |S11| ≤ −10 d...
