Knowledge sharing is a collective process where the people involved collaborate with others in order to learn from them. This effort creates communities where each member cooperates by sharing knowledge about a common domain. An example of these kinds of communities is software maintenance groups, where their members must collaborate with others, and share their knowledge and experience in orde...

The aim of this paper is to propose an adequate condition-based maintenance policy to a gradually deteriorating system using on-line detection algorithms. The originality of this work is due to the fact that the parameters defining the deterioration mode can be unknown. The main purpose is to estimate these unknown parameters in order to propose an adoptive condition based maintenance policy an...

The Road Management Systems (and the PMS) usually do not take into consideration the future traffic change. The maintenance and rehabilitation actions and the development of the road network structure and the changing traffic structure modify the amount of the traffic on the road section. The deterioration process depends on mostly the volume of the traffic. That is why it is important to take ...

in order to perform preventive maintenance (pm), two approaches have evolved in the literature. the traditional approach is based on the use of statistical and reliability analysis of equipment failure. under statistical-reliability (s-r)-based pm, the objective of achieving the minimum total cost is pursued by establishing fixed pm intervals, which are statistically optimal, at which to replac...

Scheduling has become an attractive area for artificial intelligence researchers. On other hand, in today's real-world manufacturing systems, the importance of an efficient maintenance schedule program cannot be ignored because it plays an important role in the success of manufacturing facilities. A maintenance program may be considered as the heath care of manufacturing machines and equipments...

Web sites are public representations of corporations, businesses and governmental bodies. As such they require proper maintenance to ensure that accurate and updated information is presented adequately. Dynamically created Web sites sometimes are not an option: they add a computational overhead on the server and make the automatic indexing of pages difficult. Static Web sites may grow to an ext...

1 Charles River Analytics, Inc., 625 Mount Auburn St., Cambridge, MA 02138, USA. Email: {sdas, dlawless}@cra.com Abstract We present a Network-based Truth Maintenance System (NTMS) for problem solvers based on Bayesian belief network (BN) technology. BN technology has been proven to be effective in various domains, e.g. assessing battlefield situations, such as the enemy’s likely point of inter...

results patients reported that their use of methamphetamine was motivated by methadone’s side effects and encouraged by family and friends who promoted methamphetamine use to assuage the side effects of methadone in the early stages of treatment before the appearance of methadone maintenance therapy’s effects on their life. patients and methods to gain a better understanding of patients’ motiva...

Objective: Substance dependence is the most critical biopsychosocial and legal problem. It has various harmful effects at the individual, familial, and society levels. The current study aimed to determine the effect of mindfulness-based cognitive therapy on reducing the intensity of substance dependence and improving cognitive emotion regulation in substance-dependent patients under methadone m...
