This paper deals with a reliability system hit by three types of shocks ranked as harmless, critical, or extreme, depending on their magnitudes, being below $H_1$, between $H_1$ and $H_2$, and above $H_2$, respectively. The system’s failure is caused by a...

Effectively modeling software failure behavior is crucial for reliability assessment and planning of releases. However, many current software reliability growth models assume that failures are independent and fault detection mechanisms are simplified...

Middle-censoring is a general censoring mechanism. In middle-censoring, the exact lifetimes are observed only for a portion of the units and for others, we can only know the random interval within which the failure occurs. In this study, we focus on...

The 2019 Canadian Infrastructure report card identified 60% of the subway system to be in a very poor to a poor condition. With multiple assets competing for the limited fund, new methodologies are required to prioritize assets for rehabilitation. Th...

The susceptibility of athletes to experience of emotional and psychological difficulties arising from the pressure and expectations associated with achieving and maintaining high performance can become a vulnerability in the desire to achieve success...

This paper investigates the optimal maintenance strategies for a self-repairable component under detection at fixed time intervals. The failure process of a component is considered as two parallel and competing degradation processes: an internal degr...

The study aims to provide a Bayesian statistical method with natural conjugate for facilities’ preventive maintenance scheduling related to the hybrid competing failure mode. An effective preventive maintenance strategy not only can improve a s...

Boundless outpatient therapy ‒ a study of the dynamics of long therapy courses, social development and failure: Based on their experiences with long-lasting therapy of outpatients suffering both from chronic mental disorders and social disintegration...

Both sustainability and strategic goals are realized in the course of implementing projects and in this way, projects are crucial for companies. Despite the growing importance of projects and the vast resources allocated to them, the success rates ac...

It is a well-known fact that the reproductive organs in women, especially oocytes, are exposed to numerous regulatory pathways and environmental stimuli. The maternal age is one cornerstone that influences the process of oocyte fertilization. More pr...

As Internet of Things (IoT) devices become more capable, they participate in business processes (BPs), performing process activities and making control decisions that were traditionally assigned to central systems. This creates a design-time decentra...

In the automotive industry, the implementation of Process Failure Mode and Effect Analysis (PFMEA) is conducted by a PFMEA team comprising employees who are connected to the production process or a specific product. Core PFMEA team members are active...

Female reproductive aging is associated with a progressive decline in oocyte competence and reduced success in assisted reproductive technologies. While chromosomal abnormalities, mitochondrial dysfunction, and DNA damage have been extensively studie...

Successes and failures are integral outcomes to the sport experience. Based on decades of research, how athletes process both outcomes influence their thoughts, emotions, and subsequent achievement endeavors. Attribution theory details three dimensio...
