Inertial navigation systems are of the most important and practical systems in determining the velocity, position and attitude of the vehicles and different equipment. In these systems, three accelerometers and three gyroscopes are used to measure linear accelerations and angular velocities of vehicles, respectively. By using the output of these sensors and special inertial algorithms in differ...

The procedures for purchasing surgical instruments and consumables are similar to those for purchasing equipment, which were addressed in our “Equipment for eye care” issue (number 73, September 2010). The major difference with consumables is that the number of items in stock (the ‘stock level’) must be monitored constantly. Consumables are generally fast moving and require frequent replacement...

Global logistics aim to optimize and control the material/product flow and the information flow so that materials/products can be moved at a desired pace, in a proper fashion and at the right volume. The production processes in the medical equipment manufacturing industries are highly automated and dynamic and the orders are customized. This study presents an intelligent global logistics system...

BACKGROUND Americans spend the vast majority of their lives in built environments. Even traditionally outdoor pursuits, such as exercising, are often now performed indoors. Bacteria that colonize these indoor ecosystems are primarily derived from the human microbiome. The modes of human interaction with indoor surfaces and the physical conditions associated with each surface type determine the ...

abstract background: in 2007, a rule prohibiting the use of incinerators was ratified by the iranian islamic parliament. based on this rule, the ministry of health emphasized the sterilization of infectious waste at its production source by means of non-incineration equipment and methods. this research examined the performance of non-incineration technologies in treating medical infectious and ...
