Care 3, Phase 1, volume 1

A computer program to aid in accessing the reliability of fault tolerant avionics systems was developed. A simple mathematical expression was used to evaluate the reliability of any redundant configuration over any interval during which the failure rates and coverage parameters remained unaffected by configuration changes. Provision was made for convolving such expressions in order to evaluate the reliability of a dual mode system. A coverage model was also developed to determine the various relevant coverage coefficients as a function of the available hardware and software fault detector characteristics, and subsequent isolation and recovery delay statistics

CARE 3 phase 2 report - mathematical description

CARE III (Computer-Aided Reliability Estimation, version three) a computer program designed to help estimate the reliability of complex, redundant systems is described. Although the program can model a wide variety of redundant structures, it was developed specifically for fault tolerant avionics systems. CARE III generalizes the class of system structures that can be modeled and greatly expands the coverage model to take into account such effects as intermittent and transient faults, latent faults, and error propagation

Care 3 phase 2 report, maintenance manual

CARE 3 (Computer-Aided Reliability Estimation, version three) is a computer program designed to help estimate the reliability of complex, redundant systems. Although the program can model a wide variety of redundant structures, it was developed specifically for fault-tolerant avionics systems--systems distinguished by the need for extremely reliable performance since a system failure could well result in the loss of human life. It substantially generalizes the class of redundant configurations that could be accommodated, and includes a coverage model to determine the various coverage probabilities as a function of the applicable fault recovery mechanisms (detection delay, diagnostic scheduling interval, isolation and recovery delay, etc.). CARE 3 further generalizes the class of system structures that can be modeled and greatly expands the coverage model to take into account such effects as intermittent and transient faults, latent faults, error propagation, etc

Care 3, phase 1, volume 2

A computer program was developed as a general purpose reliability tool for fault tolerant avionics systems. The computer program requirements, together with several appendices containing computer printouts are presented

CARE 3 (Computer-Aided Reliability Estimation, version three) is a computer program designed to help estimate the reliability of complex, redundant systems; although the program can model a wide variety of redundant structures, it was developed specifically for fault-tolerant avionics systems, systems distinguished by the need for extremely reliable performance since a system failure could well result in the loss of human life. CARE 3 further generalizes the class of system structures that can be modeled and greatly expands the coverage model to take into account such effects as intermittent and transient faults, latent faults, error propagation, etc. The initial test and evaluation of CARE 3 are reported

Racial Equity Considerations In Safe To Sleep Messaging: Learning From The Community

In Indiana, twice as many Black infants as White infants die in their first year of life. Infants in unsafe sleep positions are more likely to die from Sudden Unexpected Infant Death (SUID). Safe to Sleep® education has led to a dramatic decrease in mortality among White infants, but over 60% of Black families do not follow Safe to Sleep® guidelines. What is the best way to share this message with Black families

Child and Infant Mortality; Risk Factors Related to SUID in Marion County

poster abstractBetween 2003- 2012, Indiana had 434 child deaths, including 53 Sudden Unexpected Infant Death (SUID) cases. Marion County has a high rate of SUID at 14%. The purpose of our research is to identify the risk factors for suffocation and to determine if SUID can be better prevented. In a pilot exploratory study, we analyzed five de-identified Marion County SUID cases to identify the asphyxia variables. The Fetal Infant Mortality Review (FIMR) cases allowed for thematic analysis. We used a meta-aggregation program NOTARI (Narrative, opinion, text assessment, and review instrument) to focus on categorical variables. Results identified asphyxia variables such as swaddling, blanket suffocation, wedging, parents bedding, soft bedding with pillows. Common maternal variables were obesity, hypertension, and STDs. Infant variables included breathing problems and cardio-respiratory pathologies. We found four cases with documented safe sleep education. The education that parents receive on safe sleep is not a guarantee that they will practice safe sleep with their infants. The education might not be effective enough to help them comprehend its importance; therefore nurses and other healthcare professionals need to consider changing the way they educate and advocate for parents. We suggest the introduction of more primary educational programs that will help the community understand safe sleep and SUID. This intervention would help decrease the incidence of sudden unexpected infant death
