Study of Inserting Hardware Trojans into Processors
Šviková, Johana ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This bachelor's thesis focuses on a specific aspect of cybersecurity known as hardware trojans, which are insidious attacks integrated directly into electronic components. The work begins with an analysis of the architecture and function of hardware trojans, examining their various types and classifications, and exploring methods for their detection and prevention. Furthermore, the thesis investigates how these attacks can impact compromised devices and how they can pose serious security risks. This thesis contains a design and implementation of a Trojan horse for a simple processor.
Robotic Arm System for Scale Models Domain
Bruštík, Antonín ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
This thesis marginally deals with issue of industrial robots, subsequently with the design and construction of own robotic arm. It includes production process in domestic conditions with usage of commonly available components and hobby FDM 3D printer. It is closely dedicated to selection and connection of control electronics, design and consequential implementation of firmware including graphical user interface intended to demonstrate its functionality. In conclusion, it evaluates achieved results and proposes possible improvements.
Graphical Simulator of Superscalar Processors
Horký, Jakub ; Šimek, Václav (referee) ; Jaroš, Jiří (advisor)
In this thesis, I firstly focus on functional units inside processors and how they are interconnecetd in scalar and superscalar processor. Then, I describe the memory hieararchy with focus on caches. Next, I describe how compilers do translation from higher level language into assembly. Then, I have a look at available processor simulators and cache simulators and more closely describe the simulator that this thesis is based on. Thanks to the information from the analysis, I propose possible extensions to the simulator by adding memory subsystem, compiler and gathering more statistics. In the end, I have a look at my implementation and investigate possible benefits to the "Computation Systems Architectures" lectures
Automatic Determination of Positioning System Devices Coordinates from Point Cloud Data
Bucher, Michal ; Vašíček, Zdeněk (referee) ; Šimek, Václav (advisor)
Thesis describes the problem and solution of detecting anchors of localization systems and evaluating anchor position in 3D space. Position system from Sewio Networks s. r. o. requires position in 3D space for individual anchors. These anchors then gather informations about the position of individual tags in their range. The work describes some commonly used technologies for object detection and 3D data reconstruction. Compares the existing solutions in context of this work. Based on the results chooses one approach and implements it. Final gathered data with implementation are compared with real existing measurements used in the RTLS Sewio Networks s. r. o. system.
Simulation of Spread of Infectious Diseases in Human Population
Křištof, Jiří ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The aim of this work is to develop an epidemiological model to simulate the spread of the infectious disease covid-19. The developed SVLIHDRS model builds on compartmental models and is implemented as a Markov chain with continuous time. For the implementation, the UPPAAL tool is used. By comparing the simulation outputs with the observed data, the Spearman coefficients are 0.8940 for infectious individuals and 0.9987 for deceased individuals, the mean bias errors are 12510.7285 and 316.2697, respectively. The results of this thesis are useful for making long-term predictions of the epidemic evolution of covid-19 infection.
Liquid Crystal-Based Computational Platform
Klázar, Jakub ; Šimek, Václav (referee) ; Bidlo, Michal (advisor)
This work explores the possibilities of computations in a liquid crystal, specifically focusing on the logical operations. The text focuses on the design, build and use of a platform for performing experiments on computation in a liquid crystal. The platform is a device to which an LCD display can be connected as a experimental liquid crystal and experiments can be controlled from a computer through this platform. Experiments use, among other things, evolutionary algorithms. Further, the paper deals with the execution of experiments, discussion and processing of results and then creating conclusions of it.
Emulation of Character-Based LCD Display Using E-Ink Technology
Rusín, Tomáš ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The aim of this bachelor thesis is to design a simple printed circuit board interconnect. The board is planned to be equipped with a microcontroller that will receive communication signals originally intended for LCD character displays. The communication may be parallel or serial, in the form of SPI and I2C type interfaces. These signals are planned to be received and converted to E-Ink display signals. That display will show information in the same format as it was designed for LCD displays. The E-Ink display replaces LCD displays without the need of changing the original library or the original communication interface. This method of replacement is suitable when a LCD character display is destroyed and a suitable replacement cannot be found, or when the E-Ink display is more suitable.
PDU with Consumption Metering Function for Single-Board Computers
Ondráček, Roman ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
The aim of this thesis is to design a power distribution unit for single-board computers that can switch its individual outputs and also measure electrical quantities (voltage, current and power) based on the Espressif ESP32 platform and to design a web interface for the management of these power distribution units. This solution will be mainly aimed for the use of power distribution units in the development process of embedded devices built on top of single board computers. The proposed solution consists of a power distribution unit and a management information system, the communication between the different parts is done using the MQTT protocol. The information system can be used to control the individual outputs of the power distribution unit, to view graphs of the measured quantities.
Autonomous Smart Plant System
Všetečka, Radim ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
The aim of this thesis was to design and implement a smart pot for plant growth support that can be controlled through the cloud. For this purpose, it was necessary to acquaint with the ESP32 platform, cloud communication, factors affecting the plants and available sensors usable to monitor these properties. Because of the control through the internet, part of this thesis is also dedicated to the implementation of a web application that emphasizes simplicity and includes presets for different plants that can be also created by the community.
Smart Metering Device with Sigfox Interface
Janík, Jakub ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The aim of this bachelor thesis is the design and production of a measuring device using a microcontroller from the company NXP. The device sends measured values via the Sigfox IoT network, allows them to be read via Bluetooth Low Energy and monitors its own energy consumption from the battery. Any sensor whose values will be sent can be connected to the device.
