Creating playing cards "War" : diplomsko delo
Stefan Aleksoski, 2024, diplomsko delo

Opis: Playing cards stand as remarkably versatile tools, serving as a universal medium for social engagement, drawing individuals together in various settings. In this diploma, we discussed the process of creating a full deck of playing cards, their function and purpose, their elements, their packaging and printing. We analyzed successful deck of cards. In the practical part, we went through the process of creating the deck of playing cards and its packaging.

Innovative approaches to wear reduction in horizontal powder screw conveyors : a design of experiments-guided numerical study
Marko Motaln, Tone Lerher, 2024, izvirni znanstveni članek

Opis: Numerical simulations play a vital role in the modern engineering industry, especially when faced with interconnected challenges such as particle interactions and the structural integrity of conveyor systems. This article focuses on the handling of materials and emphasizes the importance of using parametric numerical analysis to improve efficiency, reduce wear, and enhance the structural integrity of horizontal screw conveyors. Through the utilization of the Design of Experiments, we systematically investigated critical parameters such as screw pitch, clearance, wear, rotational velocity, and additional structural factors. This examination was carried out within a well-defined parametric framework, utilizing a combination of software tools provided by the Ansys suite and Minitab. The findings demonstrate the effectiveness of the Design of Experiments analysis in achieving improved performance and provide valuable insights for engineers and researchers involved in the design of conveyor systems. Furthermore, this comprehensive approach clarifies how conveyor systems respond to changes in parameters and highlights the complex interaction between transported particles and the conveyor system. We present a detailed analysis that clarifies the complex relationships and dependencies among different parameters, providing engineers and researchers with valuable insights. By understanding the interactions of these factors, the methodology provides not only results but also a strategic framework for advancing conveyor system design and engineering practices.

Food Waste to Energy through Innovative Coupling of CHP and Heat Pump
Jan Drofenik, Danijela Urbancl, Darko Goričanec, Zdravko Kravanja, Zorka Novak-Pintarič, 2023, izvirni znanstveni članek

Opis: This paper presents the conceptual design of a technological solution for the efficient conversion of food waste into heat and power. The distribution and composition of food loss and waste at different stages of the food supply chain in Slovenia and their potential for biogas production were determined. It was found that more than 50% of food waste comes from households. Therefore, a small plant was designed to convert food waste into biogas, which was innovatively coupled with a combined heat and power (CHP) unit and a heat pump. This doubles the amount of heat generated compared to conventional cogeneration. Based on the capacity of a micro commercial CHP unit, 3330 households (about 8000 residents) would supply food waste. The heat generated could replace 5% of the natural gas used for domestic water heating. The payback period would be 7.2 years at a heat price of about 80 EUR/MWh, however, for municipalities with more than 40,000 inhabitants the payback period would be reduced to less than 3 years. The cost price of the heat generated by this system would be about 25 EUR/MWh, taking into account the government subsidy for the operation of the CHP unit.

Tourism experience in accessible tourism : designing a mobile application for the deaf and hard of hearing
Tjaša Alegro, Marica Ilić, Milica Rančić Demir, 2022, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Opis: How someone experiences a tourist experience depends on several factors. This article will focus on ways to ensure active participation and thus a pleasant and memorable experience for people with disabilities, specifically people with hearing problems – the deaf and hard of hearing. With the development of ICT technology, the possibilities for developing tourist products intended for the deaf and hard of hearing are even greater and can be friendlier to them. Various mobile applications complement a city’s tourist products and services and are more than a welcome help for people with special needs. With an innovative Design Thinking method suitable for planning projects or designing services or products intended for end users, we designed an idea for a mobile application for Ljubljana that is tailored to deaf and hard of hearing tourists, as Slovenia does not yet have a similar application. We designed the product idea based on an overview of good practices. Through five phases of the Design Thinking method, we analysed the indispensable elements of the mobile application for deaf and hard of hearing tourists and evaluated it through the HEART framework matrix developed for user experience assessment.
