Condition monitoring of technical systems has increasing importance for the reduction downtimes based on unplanned breakdowns. Rolling bearings are a central component machines because they often support energy-transmitting elements like shafts and spur gears. Bearing damages lead to high number machine breakdowns; thus, observing these potential reduce downtimes. The observation is challenging...

Background: Failure to establish and maintain close romantic relationships with commitment can hinder an individual’s development and have adverse effects on his/her well-being in life due to the potential emergence of serious problems. The present study aimed to investigate the relative effectiveness of acceptance and commitment therapy (ACT) and schema therapy on love trauma syndrome and self...

The paper reports an empirical study of the use of videoconferences in decentralized university education. The study focuses on breakdowns that occur during the transition of educational practices from regular classrooms to videoconference-based environments. It was found that the breakdowns were mainly caused by physical and organizational distribution of decentralized education. The paper con...

This paper investigates the role of reliability parameter of the imperfect production system with random machine breakdown and stochastic repair time. Here I assume that shifting time of the production system from ‘in-control state’ to ‘out-control state’ and the time of machine breakdown are both random. Moreover, the machine repair time is stochastic and independent of the machine break-down ...

In many industrial situations, machines are subjected to random breakdowns. In this paper, we consider the asynchronous vacation policy for the multi-server machine repair problem with server breakdown and two types of spares. According to this policy, when a certain number of servers become idle at a service completion instant, the servers will take an asynchronous vacation of random length to...

In this paper we consider single machine scheduling problems with a common due-date for all jobs, arbitrary monotone earliness and tardiness costs and arbitrary breakdown and repair processes. We show that the problem is equivalent to a deterministic one without breakdowns and repairs and with an equivalent cost function of a job's completion time. A V-shaped schedule without idle times is show...

Timely and accurate communication is essential to safe and effective health care. Despite increased awareness over the past decade of the frequency of medical errors and greater efforts directed towards improving patient safety, patient harm due to communication breakdowns remains a significant problem. Communication problems related to diagnostic testing may account for nearly half of all erro...

BACKGROUND Recent research has shown evidence of disproportionate time allocation for patient communication during multidisciplinary rounds (MDRs). Studies have shown that patients discussed later during rounds receive lesser time. OBJECTIVE The aim of our study was to investigate whether disproportionate time allocation effects persist with the use of structured rounding tools. METHODS Usi...

OBJECTIVE We developed a theoretically based taxonomy for classifying shared cognition breakdowns related to teamwork which contribute to fratricide incidents. BACKGROUND Fratricide on the battlefield is an inescapable cost of war. A number of technological advancements have been made in terms of combat identification systems to reduce the risk of these incidents. However, fratricide continue...
