Background Hair is an ectodermal structure, and its formation is regulated by master genes important in embryology. Hair shaft consists of three major regions: the medulla, cortex and cuticle. Hair shaft abnormality will divide structural hair abnormalities into two broad categories - those associated with increased hair fragility and those not associated with increased hair fragility. We condu...

Raise boring is an important method to construct the underground shafts of mines and other infrastructures, by drilling down pilot hole then reaming up desired diameter. Seriously different from operations mechanical parts in mechanized mass production, it very difficult obtain a good consistency construction environments each raise or shaft, be more exact, every process highly customized. The ...

Wind turbines are a major trend in the current green energy market. is abundant, and if utilized properly, can result significant reductions carbon emissions. Therefore, development of wind power systems urgently required. However, mainly built unmanned areas. Regular inspections require substantial manpower material resources, doubts regarding accuracy inspected data may occur. it necessary to...

The magnetic field created by technical devices is a source of information. This information could be used in contactless diagnostics and predictive maintenance or for resolving problems along with standard NDT (nondestructive testing) methods, especially if we consider large, slow-speed devices, such as electromotors, transmissions, generators. Identification causalities device failure process...

This paper presents a multi-level approach to define a product model. It is based on the concept of what we call “Intelligent” Component. In order to be able to manage contextually the different types of knowledge involved during the design process, the multi-level model reflects the different steps of the process itself. To describe the approach an applicative example related to shaft design h...
