The development of photosensitive ceramic slurries for vat photopolymerization (stereolithography or digital light processing) has received much effort in recent years. However, many these suspensions have high viscosity and they are suitable use only on equipment, specialized additive manufacturing. In this work, manufacturing using photocurable was tested a low-cost printer silicone moulds UV...

OBJECTIVES Because work-related injuries are common and yet the mechanisms through which various types of injuries relate to age, length of service and job remain unknown, this study assessed the role of age, length of service and job in work-related injury. METHODS Prospective study of all 164,814 permanently employed male workers at the French national railway company during 1998-2000, base...

INTRODUCTION: In the first half of April 2019, heavy rains in central and western parts of Iran resulted in great floods. The rains affected 24 provinces and caused extensive damage to urban and rural infrastructure. Since Iran, especially the northern, western, and southern provinces of Iran are prone to floods, the floods are expected to occur every year in many provinces. Therefore, the pres...

Introduction . The use of chrome plating as a method restoring parts that work with waterjet wear is important for the operability hydraulic drive units and used in specialized vehicles road construction equipment. proposed recovery has necessary advantages, it sufficiently high performance microhardness resulting coatings. However, implementation production, additional studies reliability coat...

In this article, new techniques and technologies have been tried and tested in the installation and commissioning of Roller Home industrial robots, in order to produce a Tiba car with a focus on cost reduction. Due to the fact that press equipment for automobile parts requires a lot of expenses, it was decided to use robots with the same function of roller to reduce costs and increase the q...

This article presents a case for practical application of the GAMM method, which has been developed and published by the authors. The GAMM method supports decision making in the overall maintenance management, through the visualization and graphical analysis of data. In addition, it allows for the identification of anomalous behavior in the equipment analyzed, whether derived from its own opera...

Both service and manufacturing industries depend on the availability of expensive equipment to deliver their products. Examples of such equipment include aircraft, rolling stock and manufacturing equipment. When this equipment is not working, the primary processes of their owners come to an immediate stop. To reduce the downtime of equipment, companies stock critical components such that the eq...

The high costs in maintaining today’s complex and sophisticated equipment make it necessary to enhance modern maintenance management systems. Conventional condition-based maintenance (CBM) reduces the uncertainty of maintenance according to the needs indicated by the equipment condition. The intelligent predictive decision support system (IPDSS) for condition-based maintenance (CBM) supplements...
