In this study, we try to develop a calibration method of control parameters included in a Monte Carlo simulation model which generates time series data for software reliability assessment. The control parameters are calibrated so as to minimize the mean sum of squared errors between the actual observed data and the generated ones. As a result, the proposed method enables us to use the simulatio...

Abstact:The term “stressstrength reliability” when it appears in statistical literature typically refers to the quantityP(X > Y), where a system with random strength X is subjected to a random strength Y such that a system fails, if the stress exceeds the strength. Stress –Strength reliability is considered in this paper where the strength follows finite mixture of two parameter Lindley distrib...

Travel time reliability has been shown to influence travelers’ decisions as to choice of destination and choice of route. This paper explores options for the inclusion of travel time reliability into a regional travel forecasting model and tests those options on a full-sized network in the Wheeling metropolitan area. Options include two different path building algorithms, different parameters (...

In this paper a method for reliability analysis of restorable items is considered. We present the model describing a variation of reliability characteristics of objects and taking into account incomplete repair of operability after failure. The asymptotic solution for the intensity of the geometric process model is obtained. Reliability characteristics of the geometric process model for various...

Background: Low bock pain (LBP)is 0 very common musculoskeletal disorder. Lumbar range of motion (ROM) and posture are parameters which are commonly assessed in LBP research. Reliable methods of measuring lumbar spine ROM and posture are needed. The CODA motion analysis system has several potential advantages over other motion analysis systems; however its reliability for lumbar spine analysis ...

This paper introduces the new approach for reliability estimation of control systems software. First we provide the basic starting points and definitions required for understanding the approach. Next we define the main parameters and variables, which are necessary for reliability estimation. The last section deals with the model for assessing the reliability of control systems software.

BACKGROUND Treadmill gait analysis was more advantageous than over-ground walking because it allowed continuous measurements of the gait parameters. The purpose of this study was to investigate the concurrent validity and the test-retest reliability of the OPTOGait photoelectric cell system against the treadmill-based gait analysis system by assessing spatio-temporal gait parameters.
