Embedded System for Water Consumption Registration
Hajdík, Tomáš ; Bidlo, Michal (referee) ; Vašíček, Zdeněk (advisor)
The bachelor thesis deals with the issue of the status of wireless water meters.The goal is to design and implement a function prototype of the embedded system based on ESP8266 Wi-Fi module that is capable of registring the amount of water, consumed by individual users, via the wireless meter readout. Users can be identified by a contactless RFID card. Embedded system ensures its availability and makes data available to the administrator via Wi-Fi network. The administrator interacts with the system by using a mobile phone and an application running on the ESP8266. The work includes hardware design and software implementation using C++ programming language. The result is a functional prototype of the system that brings new possibilities in the sphere of wireless meter readers because it does not require unaffordable and highly specialized appliances for recording consumption, is accessible from the mobile phone and thus extends the market to ordinary consumers as well.

Preventing Computer System from Computational Overload Due to Interrupts
Hajdík, Tomáš ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The master thesis deals with the techniques to prevent computer system from computational overloading due to excessive frequency of interruptions. The goal is to document the effect of interupts on a selected computing platform containing the ARM Cortex-M4 processor core. The work describes and implements possible software techniques that reduce the impact of consequences of overload due to excessive interruption frequency. At the same time the work verifies and compares the effectiveness of the particular implemented techniques by appropriate set of experiments.
