<strong><em>Abstract</em></strong><strong>—</strong> <em>With the remarkable scaling down of technology, test engineers are encountered with new challenges. With the reduction technology moving down to Deep Submicron level, the digital designs are moving closer to the probability of defects related to time. The traditional Stuck-at tests and IDDQ tests can no more detect few distinctive faults which may be occurring due to issues related to timing of the signal. The defect spectrum is thus broadened by the inclusion of other types of faults such as high impedance shorts, in-line resistan

Abstract:

Background and Objective. Heart failure (HF) is becoming an increasingly serious public health issue. The six-minute walk test (6-MWT) is a useful tool for determining the prognosis of HF patients. Due to a lack of research on their predictive relevance in 6-MWT, the goal of the study was to see if 6-MWT was indeed beneficial as a predictive indicator of death in patients with mild-to-moderate congestive heart failure. Methods. Secondary data was employed in this investigation. The 6-MWT was used to divide the walking lengths of 45 individuals with HF into two performance levels: Group I ≤3

Abstract:

A structural model for the estimation of software failure rates is proposed which is based on a partition of the code into components. Systematic failure is assumed to be induced by the interaction of these components. A Bayesian inference scheme is used to perform failure rate estimation on the basis of N failure free test runs. The approach splits the problem of constructing a system prior up into the smaller, conceivably simpler problems of constructing subtask priors. Thereby a wider range of prior information is used in the process of assessing system safety. The work in this paper consti

Four general failure-spreading mechanisms—external, temporal, spatial, and functional—are quantified to capture what drives the spreading of failures. With the failure time of each node given, the

Abstract. Plane failure along inclined joints is a classical mechanism involved in rock slope movements.

In this study, the propagation cascade effect of rock bridge failure leading to catastrophic block sliding is studied and the influence of rock bridge position in regard to the rockfall failure mode (shear or tension) is highlighted.

Abstract:

The compiler bug duplication problem (where many test failures are caused by the same compiler bug) can lead to huge waste of time and resource in diagnosing test failures produced by compiler testing. It is particularly challenging with regard to the silent compiler bugs that do not produce any error messages. To address this problem, multiple white-box techniques were proposed, but they are inapplicable in many practical scenarios. Black-box techniques are more practical, but the existing ones are less effective as they often rely on irrelevant syntactic information. To bridge this gap, we p

This highlights the need to keep tests in sync with code changes to ensure software reliability.

Rock instability occurs if the energy supplied to the rock failure process is excessive. The theoretical analysis on the energy transfer in the process of rock failure revealed that the rock failure process is a result of the strain energy released from the test machine or the surrounding rock masses of wall rock, plus the additional energy input from an external energy source if the deformation of the rock is continued and driven by the external energy source. The strain energy released from the test machine is the focus in this study because it is responsible for some of the unstable rock fa

Abstract Acceleration factors (AF) are key to designing an effective accelerated life test (ALT). They represent the ratio of the time in field to the time in test for a particular event to occur (typically a failure event related to a specific failure mechanism). Time to failure for a device generally correlates with the amount of stress applied (the higher the stress, the quicker the device will fail), and failure models exist to mathematically define that correlation for various failure mechanisms. This allows for use of a higher stress in test than in the field, thereby providing an accele

Abstract The research on automotive safety usually involves crash test experiments. These tests are very expensive, often difficult to replicate, which may lead to serious loss. This paper shows the crash test reliability analysis and classifies the risk of failure of such experiment. 46 frontal crash tests were conducted with the use of crash test dummies. All the tests were prepared according to the standard operating procedure (SOP) and the strict check list was followed before each run. All the tests were categorized for loss and analyzed for the cause of failure. Then the probability of f

Abstract:

The indirect tension test is an important laboratory test for rock characterization. The presence of rock fabric, such as schistosity, complicates the assessment of test results. One hundred and forty-five indirect tension tests were conducted on mica schist specimens to investigate the effect of schistosity orientation on failure mode and tensile strength. Tensile strength results did not provide a clear relationship between schistosity orientation and tensile strength, so the failure patterns were investigated. A new naming scheme for failure modes was developed, incorporating fracture patte

Abstract:

Extreme weather is known to cause failure bunching in electrical transmission systems. However, protection systems can also contribute to the worsening of the system state through various failure modes—spontaneous, missing or unwanted operation. The latter two types of failures only occur when an initial failure has happened, and thus are more likely to happen when the probability of failure of transmission lines is high, such as in an extreme weather scenario. This causes an exacerbation of failure bunching effects, increasing the risk of blackouts, or High Impact Low Probability (HILP) event

Abstract:

This paper presents the results of centrifuge tests on rainfall-induced instabilities in variably saturated slopes. The roles of rainfall intensity and initial conditions, such as slope angle, porosity and degree of saturation of the soil, in the failure initiation and postfailure kinematics are considered. The failure patterns, infiltration profile and deformation at prefailure and postfailure stages are characterized. The results indicate that rainfall-induced slope failures usually follow one of the following two failure modes, i.e. slide-to-flow and flowslide failure modes.

Abstract:

The scratch test is a well-established instrumental method for assessment of the cohesive-adhesive parameters of thin films and coatings. Its evaluation is classically performed using the microscopic analysis of residual scratch and the indenter depth-change record. However, these analysis methods can be insufficient for detection of the very first film-to-substrate adhesion failures. To overcome this difficulty, an independent method of detection of acoustic emission signals can be employed. The detection system of acoustic emission, developed in our laboratory, utilizes a special holder and

Abstract:

Additive Manufacturing (AM) became a popular engineering solution not only for Rapid Prototyping (RP) as a part of product development but as an effective solution for producing complex geometries as fully functional components. Even the modern engineering tools, such as the different simulation software, have a shape optimization solution especially for parts created by AM. To extend the application of these methods in this work, the failure properties of the 3D-printed parts have been investigated via shear test measurements. The layer adhesion can be calculated based on the results, which c
