“…Contrary to these maintenance strategies, Predictive Maintenance (PdM) [4,40] is known to be more viable and effective method [6,26] which has been applied to various applications such as railway network [6], diode lasers [30], aircraft [36,37], high yield etching process [10,16,38] etc. PdM technique is basically a condition-driven preventive maintenance scheme which takes into account the operational condition, efficacy and other health indicators that determine actual time needed for maintenance [22,24,25,35,36].…”

Optimal maintenance strategy On medical instruments used fOr haemOdialysis prOcessOptymalna strategia kOnserwacji urządzeń medycznych wykOrzystywanych w prOcesie hemOdializy Haemodialysis machines are one of the important medical equipment which is used to treat renal failures and minimum downtimes are thus essential. Uninterrupted and constant use of these machines in hospitals worldwide makes them vulnerable to failures if not maintained properly. Consequently, the maintenance cost for dialysis machine is high. A method to implement a cost effective maintenance strategy is demonstrated in this work. Root Cause Based Maintenance (RCBM) strategy is employed at the component level to optimize the Reliability Based Maintenance schedules derived from the existing maintenance and failure data. In order to minimize the average cost of maintenance for Haemodialysis machines and ensure their high operational availability, a Cost-Model is derived, and Genetic Algorithm is employed for optimization in this work. The application of RCBM strategy results in cost saving of about 60% of the cost incurred using current maintenance scheme. Statistical and optimization calculations are performed using Reliasoft's Weibull++ and MATLAB tools respectively.

“…Laser systems based on direct diode lasers (DDL) with a total output power at a kW level have shown their high efficiency in a number of applications and, first of all, in metalworking [1][2][3][4]. The high power of such systems is the result of inco herent (in terms of intensity) combining of a large number of optical beams going from individual diode lasers.…”

A three-section optical diode amplifier is simulated, whose sections have different amplitude-phase coupling coefficients R (linewidth enhancement factors). We show that it is possible to change the output wave phase for a constant output power due to only a difference in the value of this coefficient. In a single-mode amplifier, the first section has a horizontal waveguide formed by the gain (gainguided), and the other two sections are formed by change of the refractive index (index-guided). The values of the current in the first two sections are found, at which the phase changes by more than 2π at a constant output power of 2W. Such amplifiers can be integrated into single-crystal bars, which makes them adaptive for use in kilowatt laser systems with a coherent combining of beams.
