Maintenance is a very important part of an organization management. It significantly helps to reduce the costs and fault times of the equipment. We developed an app for mobile devices on Android platform, which efficiently enables to apply a methodology of maintenance management classification in industrial practice (maintenance performance audit). Its aim is to assist with the maintenance management assessment in terms of a comprehensive evaluation of the organization management level, which makes it an improving management decision tool based on data review and evaluation. The app automates calculations associated with the used methodology of performed audit and evaluations. The main part is to analyze the current status of maintenance management, design and implement the mentioned app. As an additional task, there was implemented a web interface, which allows users to view the app data on personal computer or tablet. © 2017 IEEE.

To meet various application requirements, it is important to enable an improvement of a-C structure and properties, such as hardness, adhesion, and wear resistance. In this study, we used the Raman spectroscopy to investigate the a-C thin films structure dependence on the different deposition parameters. The effect of nitrogen, argon, and hydrogen gas flow rate was analyzed to determine the influence on the film properties. The change in the gas type, combination, and flow had a significant influence on the D and G bands of the a-C Raman spectra. The addition of N2 into the chamber promoted the sp2 creation, while with adding hydrogen the layer contained more sp3 bonds. The depositions of a-C thin films were carried out in pulsed arc discharge vacuum installation. Micro-Raman measurements of the deposited materials were performed using an ISA Dilor-Jobin Yvon-Spex Labram confocal system with 632.8 nm radiation from a He-Ne laser using a back-scattering geometry. © 2013 M.

In this study nitrogen doped amorphous carbon (a-C:N) films were deposited on medical grade CoCrMo alloy substrates by vacuum glow discharge sputtering technique from graphite target using different deposition conditions. The influence of negative substrate bias on the thin films nanohardness was investigated. The structural properties of a-C:N films were evaluated by Raman spectroscopy.

Many research centers over the world solved problems with mobile robots for rough terrain and for human inaccessible places. There are more advantages of described solution. Miniature robot is able to work in constrained compartments and with installed camera system provide inspection of surrounding environment. Added value is possibility of chassis replacement to optimal and fast replacement of contact elements (whegs, wheel, belts). 3D integration of control electronic was based on heterostructure LTCC structure - HTCC substrate with shaped part for sensor placement. The proposed method of heterostructure creation consists of the following steps - planar lamination of LTCC structure, in the case of shaped LTCC structure its lamination in shaping preparation and burning of LTCC structure placed on HTCC substrate. During lamination process is important parameter surface quality of shaping preparation, considering that in the lamination process copying of all inequalities of the surface occurs. Technological solution has been applied during the 3D integrations of mobile mini-machine control electronics in a System on Module (SoM) assembly. © 2012 Published by Elsevier Ltd.
