Early assessment of software quality attributes plays a central role in developing better quality software. Error propagation between software system components is a quantitative factor that reflects on the reliability of a software product. We introduce a framework for experimental error propagation analysis. This framework addresses the problem of estimating error propagation at the architect...

This work analyzes the performance of reduced precision redundancy (RPR) error mitigation technique using fast Fourier transform (FFT) as a case study. To this purpose, several configurations an FFT IP design were implemented in field-programmable gate array (FPGA) triple modular (RP-TMR) and tested under proton irradiation fault injection. The cross section, sensitivity to common-mode failures...

As software architecture is becoming an important asset in the development of software systems, the study of quantitative assessment of software architectures is gaining importance due to its role in assessing their quality. Error propagation between software system components is a quantitative factor that reflects on the reliability of a software product. We introduce a framework for experimen...

The aim of this study was to determine the frequency of medication errors happened during the preparation and administration of intravenous (IV) drugs. This study was designed as prospective cross-sectional evaluations by direct unconcealed observation in a setting consisted of orthopedic, general surgery and gastroenterology wards of a teaching hospital. Participants were those patients hospit...

This document describes a number of approaches for the dependability characterization of middleware implementations, and in particular failure mode analysis of CORBA ORB implementations. The aim of the work is to provide an overall approach for identifying and quantifying failure modes using various fault injection techniques and fault models. Related work in dependability characterization of e...

Fault injection, modifying the behavior of a program to facilitate the reproduction of hidden or rare problems, is an effective technique for detecting modularity violations in programs, such as missing error handling and implementationdependent behavior. However, conventional randomized fault injection suffers from poor coverage relative to the number of tests that it runs. In this work, we in...

For a class of nonlinear systems we investigate the problem of under what conditions there exists a coordinate transformation that yields a state affine linear system up to output injection with implicit outputs. In particular, we provide necessary and sufficient conditions for time-varying linearization up to multi-output injection. We highlight that if the conditions hold, as a consequence, i...

A radio-on-dense-wavelength-division-multiplexing (DWDM) transport system based on injection-locked Fabry-Perot laser diodes (FP LDs) with four microwave carriers and large effective area fiber (LEAF) transmission was proposed and demonstrated. Good performance of bit error rate (BER) and intermodulation distortion to carrier ratio (IMD/C) over a-50 km of LEAF was obtained. Signal quality meets...
