Towards reliability of mechatronic systems-Focus on software reliability

Abstract: This paper discusses issues related to reliability of mechatronic systems and proposes a method to calculate it. Since the software reliability is the crucial aspect that can influence the entire system reliability, it deserves special attention. Hence, this paper presents in addition the influencing factors on the software reliability.

A statistical view of software reliability and modeling

Abstract: Reliability is the probability of success of a system within the mission time. There is a requirement of applying Reliability to a computer system. Software, hardware, and procedure reliability modeling and prediction have gained significant attention by the researchers over the past decades, a lot of research has been done towards hardware reliability, but relatively less research has been dedicated to studying the contribution of the human element of reliability engineering. This paper surveys what are the major keys for understanding software reliability, factors affecting software reliability, how we can design reliability in software and what are the best data collection techniques for reliability estimation. Research scholars will be benefited from this paper to understand reliability concept.

The Flexor Pollicis Longus Reflex: Interrater and Intrarater Reliability in Comparison With Established Muscle Stretch Reflexes.

Abstract: Objective The aim of this study was to investigate the interrater reliability and intrarater reliability of the flexor pollicis longus muscle stretch reflex (FPLR) and compare it with clinically established reflexes. Design A total of 71 healthy volunteers participated. The FPLR, biceps reflex, brachioradialis reflex, and patellar tendon reflex of each participant were tested bilaterally and rated by eight examiners (four experienced, four inexperienced). For intrarater reliability evaluation, five examiners rated the reflexes of four volunteers at four different points in time. Results Analysis of the interrater reliability with Gwet's AC1 demonstrated almost perfect agreement for FPLR (Gwet's AC1 = 0.90), biceps reflex (Gwet's AC1 = 0.90), and patellar tendon reflex (Gwet's AC1 = 0.95) when using binary data (reflex present vs. absent). Only fair agreement was found for the brachioradialis reflex (Gwet's AC1 = 0.56). Experienced raters had a higher agreement than inexperienced raters did when rating the biceps reflex and the patellar tendon reflex. The intrarater reliability was almost perfect for the patellar tendon reflex (Gwet's AC1 = 0.94), followed by the FPLR (Gwet's AC1 = 0.83) with substantial agreement and the biceps reflex (Gwet's AC1 = 0.57) with moderate agreement. Conclusion The FPLR is a reliable diagnostic neuromuscular test and may therefore be useful in the clinical examination for C8/T1 nerve root lesions or pathologies of the interosseous anterior nerve.

A reliability data base for performance and predictive assessment of electric power systems

Abstract: The authors present an overview of the CEA reporting procedures for assessing overall power system performance and providing generation, transmission and distribution outage statistics which can be used to predict future performance. The equipment Reliability Information System (ERIS) is presented with particular emphasis on the ability of the system to provide the necessary reliability parameters to support the conventional models used in reliability evaluation. The Electric Power System Reliability Assessment (EPSRA) procedure is briefly described. This procedure, when fully implemented, should provide an extremely important source of comparative utility performance data.
