A broadband microstrip bandpass filter (BPF) with compact size, sharp skirt and wide upperstopband performance is proposed using the triple-mode stub-loaded resonator. The resonator can generate one odd mode and two even modes in the desired passband. Due to the main path signal counteraction, two transmission zeros Tz1, Tz2 can be created near the passband edge to achieve sharp skirt. Two tran...

In this study, a new refractive index sensor based on a metal-insulator-metal waveguide coupled with a notched ring resonator and stub is designed. The finite element method is used to study the propagation characteristics of the sensor. According to the calculation results, the transmission spectrum exhibits a typical Fano resonance shape. The phenomenon of Fano resonance is caused by the coup...

This paper presents a new dual-mode stub-loaded resonator, which consists of a microstrip resonator with internal coupled lines and an open-circuited stub. Based on the oddand even-mode equivalent circuits, the resonant characteristics of the proposed microstrip resonator are investigated. It is found that the fundamental even-mode resonant frequency of the proposed resonator can be flexibly co...

A wideband planar inverted-F MIMO antenna with high isolation is proposed in this letter. The proposed MIMO antenna consists of two back-to-back planar inverted-F antennas and a forkshaped decoupling stub. The two planar inverted-F antennas are merged together with a shorting strip connected to the ground plane. In order to enhance the isolation, a fork-shaped decoupling stub connected to the g...

JavaScript is expected to be a programming language of even wider use, considering demands for more interactive web/mobile applications and deployment in server-side software. While reliability of JavaScript code will be of more importance, testing techniques for the language remain insufficient, compared to other languages. We propose a technique to automatically generate high-coverage unit te...

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...

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, ...
