TL;DR: In this article, the authors discuss the formation of reliability objectives and the methods of reliability goal allocation in the design of telephone switching systems, and the sequence of reliability design functions can be expressed as follows: 1) The formation of the reliability objectives, 2) The allocation of these objectives, 3) The modeling to verify the reliability obtained.
Abstract: In the design of telephone switching systems, the sequence of reliability design functions can be stated as 1) the formation of reliability objectives, 2) the allocation of these objectives, and 3) the modeling to verify the reliability obtained. Optimization techniques can be used in both reliability allocation and reliability modeling. This paper discusses the formation of reliability objectives and the methods of reliability goal allocation. Modeling examples are presented of a component-level reliability vs. cost trade-off and a system-level reliability analysis.

TL;DR: The results demonstrated the high reliability of the total ULPRS score within and between raters and supports the clinical utility of the UL PRS as an outcome measure of spastic upper limb in children with CP.
Abstract: Purpose: The Upper Limb Physician’s Rating Scale (ULPRS) is a tool that assesses movement quality of the upper limbs. It is used as an outcome measure after botulinum toxin type A injection in children with cerebral palsy (CP). This study aimed to investigate the reliability and validity of the ULPRS in children with spastic CP. Materials and Methods: Thirty children with spastic CP (M:F=17:13) aged 5 to 13 years old were recruited. The ULPRS was scored based on recorded videotapes by four physicians on two separate occasions. The Melbourne Assessment of Unilateral Upper Limb Function (MUUL) was scored by an occupational therapist. Intraclass correlation coefficients (ICCs), 95% confidence intervals and weighted kappa statis tics were calculated for the scores of ULPRS to obtain interrater and intrarater reliability. The relationship between ULPRS and MUUL was assessed using Pearson correlation coefficients. Results: The ICCs for the total ULPRS scores were 0.94 between raters and 0.99 to 1.00 within raters. The weighted kappa statistics for subitem scores for the ULPRS ranged from 0.67 to 1.00 within raters and from 0.46 to 0.86 between raters. The relationship between ULPRS and MUUL was strong (Pearson correlation coefficient=0.751; p<0.05). Conclusion: The results demonstrated the high reliability of the total ULPRS score within and between raters. A significant concurrent validity between ULPRS and MUUL also supports the clinical utility of the ULPRS as an outcome measure of spastic upper limb in children with CP.

TL;DR: The short spiral pelvimetry demonstrated high and best reliability in comparison to other methods: standard spiral and short spiral, which might be suitable for measurements at narrow pelvis.
Abstract: BackgroundDifferent low-dose computed tomography (CT) pelvimetry methods can be used to evaluate the size of birth canal before delivery. CT pelvimetry might generate an acceptable low fetal radiat...

TL;DR: In this article, the performance of raters to assess locomotion in dairy cows and to study relations between five traits (arched back, asymmetric gait, head bobbing, reluctance to bear weight and tracking up) and locomotion was determined.
Abstract: In lameness research, five-level locomotion scores are used. The objective of this study was to determine the performance of raters to assess locomotion in dairy cows and to study relations between five traits (arched back, asymmetric gait, head bobbing, reluctance to bear weight and tracking up) and locomotion in dairy cows. Locomotion and traits were scored on a five-level ordinal scale. Ten experienced raters scored 58 video records of different cows in two scoring sessions. Intrarater and interrater reliability and agreement were calculated as weighted kappa coefficient (?w), percentage of agreement (PA) and specific agreement for individual levels of the scale (SA). The relation between locomotion score and traits was estimated by a logistic regression aiming to calculate the size of the fixed effects on the probability of scoring a cow in one of the five levels of the scale. Intrarater reliability ranged from ?w=0.63-0.86 whereas intrarater agreement ranged from PA=60.3-82.8%. Interrater reliability ranged from ?w=0.28-0.84 and interrater agreement ranged from PA=22.6-81.8%. The intrarater SA were 76.4% for level 1, 68.5% for level 2, 65.0% for level 3, 77.2% for level 4 and 80% for level 5. Interrater SA were 64.7% for level 1, 57.5% for level 2, 50.8% for level 3, 60.0% for level 4, and 45.2% for level 5. All traits were significantly related to locomotion, being the most important reluctance to bear weight, asymmetric gait and arched back. Interactions between rater and session, and rater and tracking up were significant. In conclusion, experienced raters showed a variable performance to assess locomotion and locomotion traits in dairy cows. Variability of raters should be considered for on-farm utilization of locomotion scoring.
