Morphology of my bacteria III.
Procházková, Kateřina ; Mitro, Michal (referee) ; Mikyta, Svätopluk (advisor)
In my bachelor thesis titled "Morphology of my bacteria III.", I focus on a series of objects and prints depicting a parasite defined by me. Using the technique of screen printing, I portray the subject as a symbol of personal encounters with health difficulties. This results in an infinite number of growing parasites, bacteriological or virological motifs, and morphological shapes. Screen printing is primarily utilized in the work for its ability to multiply and layer, each time with a different outcome.

The Quiet Omnipresence
Bodlák, Ondřej ; Dvořák, Vojtěch (referee) ; Mikyta, Svätopluk (advisor)
The work, entitled The Quiet Omnipresence, themes the metaphor of grid and line as representing the source elements necessary for the growth of whole forms. It relies on a study of landscape and urban scenery, its quiet ubiquitous mechanisms and processes. The jumble of lines creates a sensorially elusive monochromatic surface that the observer can encounter when looking at organic structures for longer periods, as well as industrially tuned urban compositions. It explores the relationship of order and chaos in its opposite but paradoxically mutually inexorable connotations. The work mostly relies on a specific and not uncommon type of space often right in the middle of cities – vague terrains, places forgotten and deliberately overlooked, in which banal biological processes slowly take the helm determining the direction of a seemingly random development.

Simplified Multiplication in Convolutional Neural Networks
Juhaňák, Pavel ; Jaroš, Jiří (referee) ; Sekanina, Lukáš (advisor)
This thesis provides an introduction to classical and convolutional neural networks. It describes how hardware multiplication is conventionally performed and optimized. A simplified multiplication method is proposed, namely multiplierless multiplication. This method is implemented and integrated into the TypeCNN library. The cost of the hardware solution of both conventional and simplified multipliers is estimated. The thesis also introduces software tools developed to work with convolutional neural networks and datasets used to test them in the image classification task. Test architectures and experimentation methodology are proposed. The results are evaluated, and both the classification accuracy and cost of the hardware solution are discussed.

Laboratory device with analog computational unit AD538
Hruboš, Zdeněk ; Slezák, Josef (referee) ; Petržela, Jiří (advisor)
An analog multiplier are circuits, that are realized multiplication of two analog signals. They can be made by suitable connection (according to function) discreet parts. Nowadays there are integrated circuits in advance function, whose internal structure is made by complex of circuits with operating ampfliers and other circuits. These circuits have a very high accuracy of arithmetic operation which is mostly better than 1%. The analog multiplier are used in situation, when we need realize multiplication, division, exponentation, square root extraction and logarithmic calculation of analog signals. In the next are used in circuits for multiplication of frequency, shifting of frequency, amplitude modulation, detection phase angel of two signals with the same frequency, etc. The AD538 is a monolithic real-time computational circuit that provides precision analog multiplication, division and exponentiation. The combination of low input and output offset voltages and excellent linearity results in accurate computation over an unusually wide input dynamic range.

Accurate wattmeter for measure power loss in feromagnetic controlled AVR
Smutný, Martin ; Drexler, Petr (referee) ; Roubal, Zdeněk (advisor)
Electronic wattmeters excel in very small (up to negligible) own consumption. The basiccomponents of these devices is the multiplier - a circuit whose output voltage is proportional to the product of input voltage. Wattmeter is a device that contains two coils, one of which is the current coil voltage and the second coil. Current coil is connected in series with the measured electrical circuit and the voltage measuredparallel to the coil circuit. Current flowing through the coil current causes a magnetic field is proportional to the current flowing through the phase shift and. Electromagnetic fields of both coils influence each other in case of measurements in a DC circuit, the resultingdeflection proportional to both voltage and current. When measured in AC electrical powercircuits can be determined using the effective values of current and voltage, and their mutualphase shift. A magnetic induction B can be determined using mean values. An analog multiplier are circuits, that are realized multiplication of two analog signals. They can be made by suitable connection (according to function) discreet parts. Nowadays there are integrated circuits in advance function, whose internal structure is made by complex of circuits with operating ampfliers and other circuits.
