Peer Analysis in the Cryptocurrency Networks
Jeřábek, Vladimír ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
The aim of this thesis is to create a tool that will collect relevant information about active nodes in a Bitcoin peer-to-peer network. We are able to collect important data for more detailed analysis by monitoring the behavior of individual nodes on the network . The proposed solution uses unmodified Bitcoin Core client, which connects to all reachable nodes on the network. The platform has modular design, which offers good scaling as well. Created BiNMo tool (Bitcoin Network Monitor) also employs simple visualization of gathered data. The correct functionality of the monitoring platform was verified in the real operation, where it was monitoring Bitcoin network for more than two months. During that time, BiNMon parsed over 12 TiB of network data and stored over 270 GiB of metadata about active nodes. The entire platform can be deployed within a few minutes, thanks to Docker containerization.

Darkmarket Forensics
Dolejška, Daniel ; Grégr, Matěj (referee) ; Veselý, Vladimír (advisor)
Overlay networks (like Tor or I2P) create a suitable environment for criminality to thrive on the Internet. Dark marketplaces (a.k.a. cryptomarkets) are one such example of criminal activities. They act as an intermediary in the trade of illegal goods and services. This project focuses on forensic analysis of such web services and subsequent extraction of non-trivial information about the realised orders and payments from selected marketplaces. The main goal is to pinpoint the time interval when an order has been completed on selected marketplaces and its following correlation with cryptocurrency blockchains. The implemented program provides fully automated non-stop monitoring of selected cryptomarkets. That, under certain conditions, allows detection of realised purchases, detailed product and vendor monitoring and collection of various meta-data entries. Law enforcement agencies can use acquired data as support evidence regarding the operation of selected cryptomarkets and their vendors. The obtained information can also indicate current trends in products supply and demand.

Monitoring centrálních bank - prosinec 2017
Česká národní banka
Most of the central banks under review, including the ECB, are keeping their interest rates at low levels, and several are also continuing their unconventional monetary policy programmes, although the ECB, for example, has reduced its monthly asset purchases. A major exception is the US Fed, which, as expected, is continuing to raise its key interest rate and, according to outlooks, will maintain this trend next year. The UK has also seen its first rate hike in ten years. By contrast, the Hungarian central bank’s new instruments are aimed at lowering yields at the longer end of the yield curve. Spotlight focuses this time on the countercyclical capital buffer. In our Selected speech, outgoing Fed Chair Janet Yellen sums up US monetary policy over the last ten years.

Design and developement of autonomous system for monitoring critical paramaters in food industry
Chovan, Hynek ; Formánek, Martin (referee) ; Krejčí, Petr (advisor)
his work focuses on automating the monitoring of temperature and other operational parameters in gastronomic establishments. The designed device allows real-time monitoring of temperature, humidity, and other parameters with remote access capability. It utilizes the ESP32 microcontroller, SHT40 and HX711 sensors, and TP4056 charging circuit with DW01A protection circuit. Data is transmitted to a Gateway device, which displays it through a web interface. Testing demonstrated sufficient communication range and long battery life. The device meets requirements for compactness, reliability, and efficiency. This project represents progress in IoT applications for ensuring food safety and efficiency in handling food in gastronomic establishments.

Training tracking using NFC technology
Blažík, Vojtěch ; Zachariášová, Marcela (referee) ; Strnadel, Josef (advisor)
This bachelor thesis describes the development of mobile application which uses NFC technology for training tracking and monitoring of gym equipment usage. The work summarizes the basic motivation and approaches to training and equipment tracking as well as NFC technology and mobile app development focused on the multiplatform framework Flutter. The resulting app is based on the client-server architecture with offline mode support and uses the identifiers of deployed NFC tags to identify the machine and exercises. The goal of this work is to show a functional system, which incorporates this technology in an unconventional way to achieve a higher user comfort.
