Maintenance supply chain for nuclear power plants : information technology support for human resources management
Andrej Androjna, Robert Bizjak, Bojan Rosi, 2009, original scientific article

Abstract: The paper is looking at a case on IT support of HR management in a maintenance supply chain for nuclear power plants and analyzing a specific solution developed by NUMIP Ltd. The database NOS Data developed by NUMIP Ltd.has proved to be an efficient tool for the intended purpose and size of the current application. Yet there is a clear potential for improvement of the tool in the future, mainly related to direct electronic data exchange with customers and subcontractors, as well as to implementation of requirements of nuclear plants from different markets. The case study provides a description of a relatively complex requirement structure that applies to outsourced personnel working in maintenance activities in a nuclear power plant. The area is rather poorly covered in literature, hence the paper may be of interest to practitioners and students, as well as researchers.

A fuzzy model of power supply system control
Janez Usenik, 2012, original scientific article

Abstract: In this article, a mathematical model of control of a dynamic system is described; one such system could be a power supply system. Analytical approaches that have been developed to describe the influence of production and stock, i.e. additional capacities, require a hierarchical spatial pattern and demand. Demand is usually an inherently stochastic process, but in this article we simulate it as an output fuzzy variable in a fuzzy system, in which all the input variables are also fuzzy. Furthermore, an interesting use of neural sets is shown, which is presented as an efficient method for the optimisation of the fuzzy system. At the end, a numerical example is given.

The development of ARM-based portable and adaptable power supply
Tomislav Brlek, 2019, master's thesis

Abstract: This master’s thesis describes a development of a portable and adjustable power supply. The first part of the thesis introduces us to the working principle of power supplies in general. Next, we present a functional design of a portable and adjustable power supply and a list of its required functionalities. Chapter “switched-mode power supplies” introduces us to the theoretical basics of the said power supplies, while chapter “linear regulators” introduces us to different types of linear regulators and tells us more about how they work. Everything regarding which microcontroller was used and why it was used is described in the “ARM microcontroller” chapter. Besides microcontrollers, it also talks about which integrated development environment is used and how the microcontroller is programmed. A full and detailed description of each part of the analog circuitry can be found in the chapter “describing the development of the portable and adjustable power supply”. Lastly, the user interface is described in detail.
Keywords: portable power supply, ARM processor, variable laboratory bench power supply, LCD touchscreen, energy efficient, lithium battery, battery charger, voltage control
