Because of the increasing complexity of the applications running in Kitten, a lightweight HPC OS targeted for compute nodes of massively-parallel, distributed-memory supercomputers, and the complex hardware that Kitten is running on, bugs are becoming more difficult to find. As a result, the need for Kitten to support user-level application debugging becomes more critical. Unfortunately, Kitten...

This document describes a backward-compatible technique that may be used by OSPF (Open Shortest Path First) implementations to advertise a router's unavailability to forward transit traffic or to lower the preference level for the paths through such a router. (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Int...

Fast flux networks represent a special type of botnets that are used to provide highly available web services to a backend server, which usually hosts malicious content. Detection of fast flux networks continues to be a challenging issue because of the similar behavior between these networks and other legitimate infrastructures, such as CDNs and server farms. This paper proposes Fast Flux Watch...

This paper proposes a new Feature Interaction (FI) ltering method at the requirements level. FI ltering is to screen out some irrelevant feature combinations before the FI detection process, by using simple indications that certain combinations are likely to cause FI. To achieve this, we extensively utilize a requirement notation method, called Use Case Maps (UCMs), which helps designers to vis...

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...

Object Infrastructure Framework The goal of the Microelectronics and Computer Technology Corporation’s (MCC) Object Infrastructure Project (OIP) is to simplify the development and evolution of distributed, object-oriented applications. OIP is designing an architecture for distributed systems (a set of rules for distributed, component-based systems to follow) and implementing frameworks. (Such a...

Abstract: In this paper a novel radial stub feeding microstrip bow-tie antenna is designed to operate between C and X band and its performance characterization is presented. This antenna is having simple structure and topology over other stub loaded antennas. In addition the proposed antenna adjusts to the desired frequency easily. Antenna output parameters like radiation pattern, axial ratio, ...

In distributed object systems, one generates local surrogate objects to achieve transparent remote method invocations. These surrogates intercept method invocations, transfer the invocations to the actual (remote) object, and invoke the respective method by using so-called stub code. We describe a method which automatically generates surrogate and stub code. The actual generation is delayed unt...

A novel compact-sized ultra-wideband (UWB) bandpass filter (BPF) is proposed in this paper. The proposed BPF is highly selective and is able to eliminate WLAN signals from 5.15-5.35 GHz, and downlink of X-band satellite communication signals from 7.25-7.75 GHz. Generally, a multiple-mode resonator (MMR), comprised of a U-shaped line, with two high impedance stubs connected to it, and one steppe...
