1. Optimal bus stops' allocation : a school bus routing problem with respect to terrain elevationKlemen Prah, Abolfazl Keshavarzsaleh, Tomaž Kramberger, Borut Jereb, Dejan Dragan, 2018, original scientific article Abstract: The paper addresses the optimal bus stops allocation in the Laško municipality. The goal is to achieve a cost reduction by proper re-designing of a mandatory pupils' transportation to their schools. The proposed heuristic optimization algorithm relies on data clustering and Monte Carlo simulation. The number of bus stops should be minimal possible that still assure a maximal service area, while keeping the minimal walking distances children have to go from their homes to the nearest bus stop. The working mechanism of the proposed algorithm is explained. The latter is driven by three-dimensional GIS data to take into account as much realistic dynamic properties of terrain as possible. The results show that the proposed algorithm achieves an optimal solution with only 37 optimal bus stops covering 94.6 % of all treated pupils despite the diversity and wideness of municipality, as well as the problematic characteristics of terrains' elevation. The calculated bus stops will represent important guidelines to their actual physical implementation.

2. Indoor mapping and navigation using geographic information systemsGoran Sekirarski, 2016, bachelor thesis/paper Abstract: This study present proposal work with prototypes that use Radio-Frequency Identification (RFID) and NFC technology for indoor navigation using mobile device with help by using geographic information system to create geotagged maps to building in this diploma thesis. The study used an experimental approach with open source software and hardware engineering tools and technologies which minimized cost. A preliminary experiment with RFID and NFC tools helped to understand the compatibility of certain RFID infrastructure with NFC and helped to determine if and how NFC could be used. The capability of NFC in leveraging its low-cost infrastructure of passive tags, its embedment in mobile devices and the ubiquity of the mobile device provided a cost effective solution with good accuracy.
