In the automotive context On-Board Diagnostics, or OBD refers to a vehicle's self-diagnostic and reporting capability and presents the vehicle owner or a repair technician with state of health information for various vehicle sub-systems. Earlier systems of OBD could simply illuminate a malfunction indicator light, or MIL, if a problem were detected--but the nature of the problem could not be specified.

But by the introduction of on-board vehicle computers in the early 1980's, which had made OBD possible the amount of diagnostic information ....etc

Clos Architecture in OPS

The need to transmit information in large volumes and in more compact forms is felt these days more than ever before. To provide the bandwidth necessary to fulfill the ever-increasing demand, the copper networks have been upgraded and nowadays to a great extend replaced with optical fiber networks. Though initially these were deployed as point-to-point interconnections, real optical networking using optical switches is possible today. Since the advent of optical amplifiers allowed the deployment of dense wavelength d ....etc

ABSTRACT
This paper describes the application of two relatively new diagnostic techniques for the determination of insulation condition in aged transformers. The techniques are (a) measurements of interfacial polarization spectra by a DC method and (b) measurements of molecular weight and its distribution by gel permeation chromatography. Several other electrical properties of the cellulose polymer were also investigated. Samples were obtained from a retired power transformer and they were ana ....etc

REAL-TIME MONITORING AND ASSESSMENT OF CIRCUIT BREAKER OPERATIONS FOR DIAGNOSTICS AND CONTROL APPLICATIONS
Abstract:
Circuit breakers (CBs) are very important elements in the power system. They are used to switch other equipment in and out of service. Circuit breakers need to be reliable since their incorrect operation can cause major issues with power system protection and control. Today’s practice in monitoring circuit breaker operation and status in real tim ....etc

Medical information implies all information related with treatment of the patient, and is, by its nature, the most sensitive and important information in terms of the privacy of the individual. Recently, laws, policies, and technological standards are rapidly developing to safely protect the medical information of the individual. This paper proposes a model that applies fingerprint recognition technology to the medical information system, to guarantee a reliable electronic medical record system. The proposed model provides an identification and ....etc

The safety of future manned missions to the moon and Mars hinges upon a proper understanding of how fires behave in outer space zero gravity/ micro gravity environments. Past studies have been limited to low oxygen concentrations and configurations in which the high velocity fuel enters an oxidizing atmosphere. However, one important fire scenario in outer space is a high velocity high oxygen oxidizer jet encountering fuel (an inverse flame configuration). This study focuses on flame shapes of oxygen- enhanced flames in inverse and normal diffu ....etc
