OBJECTIVE The purpose of this study was to evaluate quantitatively the basic parameters of the video laryngostroboscopy (VLS) and determine the sensitivity and specificity of these parameters discriminating healthy and pathological voice classes. METHODS Digital VLS recordings were performed for 159 individuals: 26 healthy and 133 patients. VLS variables (glottal closure, regularity, mucosal ...

Here we investigate the underlying basis connecting the the software reliability growth models to the software testing and debugging process. This is important for several reasons. First, if the parameters have an interpretation, then they constitute a metric for the software test process and the software under test. Secondly, it may be possible to estimate the parameters even before testing be...

Software reliability is an important characteristic for most systems. A number of reliability models have been developed to evaluate the reliability of a software system. The parameters in these software reliability models are usually directly obtained from the field failure data. Due to the dynamic properties of the system and the insufficiency of the failure data, the accurate values of the p...

In software development process, testing is one of the most important aspects and hence, software reliably is very important factor of software systems. In the last four decades many software reliability growth model based on non-homogeneous Poisson process (NHPP) have been developed which incorporates testing effort function. However, the previous models are quite helpful for software engineer...

Many architecture–based software reliability models were proposed in the past. Regardless of the accuracy of these models, if a considerable uncertainty exists in the estimates of the operational profile and components reliabilities then a significant uncertainty exists in calculated software reliability. Therefore, the traditional way of estimating software reliability by plugging point estima...

Objective: The objective was to estimate the reliability of three stiffness parameters (moment, angle and stiffness coefficient) of the hip extension movement, for three knee positions. Design: Twenty healthy subjects were assessed on two days separated by a one-week interval. A modified Biodex dynamometer was used to move the right lower limb passively in a side-lying position and to record th...

Since the 1990s, the increasing deployments of networked automation systems led to increased manufacturing productivity, improved interchangeability of devices from different vendors, facilitated flexibility and reconfigurability for various applications and improved reliability, while reducing installation and maintenance costs. However, the reliability of a network has great impact on the rel...

By analyzing the reliability of a system, it is very often assumed that all probabilities are precise, that is, that every probability involved is perfectly determinable. However, the information about reliability of components may be supplied by experts and it is difficult to expect that all experts provide precise and true reliability assessments. One of the promising tools for dealing with s...
