Opis: In modern society, which is characterized by process of rapid change in the logistics sector, including supply chain, transport and Internet protocols, and which are partly conditioned by changes due to the COVID-19 pandemic, placement and sale of products within retail chains requires a stronger marketing strategy which would significantly promote the benefits of their purchase. Based on the presented facts, we can state that the logistics management process, which includes supply chain risk management, is a continuous task whose main task is to anticipate possible risks, take action during their period and minimize the consequences of all forms (types) of risk business. Every institution and economic organization in our country should seriously and continuously approach the identification of risks by the type of risk and appropriate action to eliminate it. The consequence of adequate risk management is transparent and more efficient business operations that lead to a more prosperous and profitable business. The type and manner of risks, as well as the definition of measures and strategies that will be applied to eliminate them, requires a significant commitment of funds. Sometimes it is enough to react in time and prevent actions that require minimal engagement to prevent consequences that can have significant negative consequences such as domino effects. The consequences of the economic sector, actions, and measures taken often have a consequential impact on the country's overall political, social, and economic system. Therefore special attention is paid to the protection and prevention of risks in banking to avoid sudden changes and adverse effects of monetary policy. The contribution to market stability is of public and national interest, so paying more attention to one of the primary problems in business and risk management. Within the operation of the economic system, there are a large number of employees, and therefore it is vital to properly delegate functions, powers, and tasks and, by them, adequate responsibilities, obligations, tasks, rights, and consequences. The work aims to analyze different types of logistics system operations and ways of classifying their functions in supply. Also, the work tries to identify the most critical subjects of logistics services. The work aims to also analyze different types of operations of logistics systems, as well as how their functions are classified, namely functions that facilitate the supply of a particular area. This master's thesis aims to identify the most critical subjects of logistics services within the management of logistics operations with intermediaries' participation and identify their tasks and objectives. The first part of the master's thesis is dedicated to supplying chains as an integral part of logistics systems in economics, their concept and significance, their supply chain management goals, its key components, significance and type of supply chain risks, and their impact on logistics. The second part of the master's thesis is dedicated to the role of transport within logistics systems, the concept, function, and importance of intermodal transport within logistics, the importance and share of intermodal transport costs in the logistics system, and the role of logistics in intermodal transport in the European Union and the USA. The third part of the master's thesis deals with explaining Internet protocols within logistics, defining the concept with an explanation of the elements and functions of Internet network protocols, and the levels of the reference OSI model. In the fourth part, the functioning of logistics within the company LIDL is presented. In the last part of the master's thesis, there are concluding remarks with the used literature.

Opis: Spletni radio je oblika množičnega komuniciranja, ki z uporabo pretakanja omogoča širitev radijskega programa preko interneta. Od tradicionalnega radia se razlikuje po geografski neomejenosti, usmerjenosti nišnemu občinstvu in potencialno večji interaktivnosti s svojimi poslušalci. Večina poslušalcev za poslušanje glasbe ne posega več po radijskem sprejemniku, ampak uporablja mobilno napravo povezano z internetom. V tem diplomskem delu so analizirane uporabljene tehnologije, gradniki in oblika treh spletnih strani radijskih postaj. Na podlagi teh ugotovitev smo ustvarili lastno odzivno spletno rešitev - spletni radio, katerega namen je prikaz možnosti nadgraditev obstoječih spletnih strani radiev.

Opis: Delo obravnava razvoj informacijskega sistema za upravljanje ogrevanja s tehnologijami interneta stvari. Opisano je razvojno okolje, ki je vključevalo Visual Studio Code, PlatformIO, VirtualBox, Ubuntu Linux, node.js, Raspberry Pi in module ESP32. Opisana je struktura sistema za upravljanje ogrevanja, kjer je vključenih več tipal temperature, tipalo razdalje ter relejski modul. Pri realizaciji sistema je bilo uporabljenih šest modulov ESP32. Opredeljena je bila zasnova sistema s strežnikom, strojnimi moduli, tipali, klienti ter način komunikacije med elementi sistema. Opisana je realizacija postopka identifikacije modulov ESP32 ter komunikacija med moduli ESP32, strežnikom node.js ter klientom. Komunikacija med elementi sistema je bila izvedena prek zapisov v obliki json. Opisan je razvoj uporabniškega vmesnika, do katerega dostopamo prek brskalnika na telefonu oz. katerekoli naprave, ki ima vgrajen brskalnik. Razviti uporabniški vmesnik omogoča prikaz šestih različnih temperatur in tudi želene temperature. Prek vmesnika se da nastaviti želeno temperaturo ogrevanja. Opisana je razlika med različnimi načini komunikacije med moduli ESP32 in strežnikom node.js. Za zapis podatkov je bila uporabljena podatkovna baza Lowdb. Prototip sistema je bil uspešno testiran prek namenske spletne strani termostat.si.

Opis: Namen diplomskega dela je bila predstavitev energijsko varčne, a vseeno natančne alternative signalom globalnega pozicioniranja GPS, ki se ponavadi uporabljajo za sledenje aktivnosti na kolesu z uporabo mobilne aplikacije. Najprej smo predstavili trenutno stanje na trgu in opisali, zakaj smo se odločili poiskati alternativo. Implementacija naše rešitve je zasnovana s pomočjo magnetnega senzorja, ki na vsak vrtljaj kolesa pošlje signal mikrokrmilniku ESP32. Le‐ta filtrira, obdela in periodično pošilja pridobljene podatke uporabniški aplikaciji, kjer se vizualizirajo. Prav tako je na mikrokrmilnik povezan senzor za temperaturo, vlago in pritisk, ki nam omogoča izračun trenutne nadmorske višine s pomočjo barometrične enačbe. Omenjeno rešitev smo testirali z vožnjo kolesa po cesti ter analizirali pridobljene rezultate. Odstopanje med referenčnimi vrednostmi in našimi meritvami je do 5 % oziroma do 10 % v primeru izračuna nadmorske višine, medtem ko je poraba energije vsaj 3‐krat manjša v primerjavi s konkurenco na trgu.

Opis: The number of Internet of Things devices has been increasing rapidly in the recent few years, which opens possibilities for many new use cases. One of those is tracking assets, specifically for the conservation of endangered animals. This is the main goal of the OpenCollar tracking device. Its features and communication technologies are described in this master’s thesis. The device supports a variety of configuration options enabling users to tweak it for their specific usage. The main focus of the thesis was to design, implement, and test a cross-platform mobile application that would simplify the configuration process of such a device. All aspects of the application are described with a focus on the communication protocol. In the end, we present the results and conclude that the implemented application greatly simplifies the management of OpenCollar devices.
