Thesis discusses about different ways of a communication between components of a distributed system. It describes a communication using a message exchange and at the same time talks about other alternatives. It adds details about various models of a message exchange, various message types and about various specifications as well. Commercial tools ActiveMQ, RabbitMQ and Kafka are presented. Special emphasis is placed on describing the way these tools exchange messages, scalability options and others. The web service is designed according to the described features. Its main purpose is management and monitoring of the tool by user choice and easy replacement of this tool with another one. Designed application is implemented using the Kotlin language for selected tool RabbitMQ. The implemented solution allows a simple exchange of messages through the REST api.

The goal of this diploma thesis was to create four laboratory exercises for the subject "Parallel Data Processing", where students will try on the options and capabilities of Apache Spark as a parallel computing platform. The work also includes basic setup and use of Apache Kafka technology and NoSQL Apache Cassandra database. The other two lab assignments focus on working with a Travelling Salesman Problem. The first lab was designed to demonstrate the difficulty of a task where the student will face an exponential increase in complexity. The second task consists of an optimization algorithm to solve the problem in cluster. This algorithm is subjected to performance measurements in clusters. The conclusion of the thesis contains recommendations for optimization as well as comparison of running with different number of computing devices.

Cílem této práce je vytvořit platformu pro sběr a zobrazování metadat o kryptoměnových adresách z veřejného i temného webu. K dosažení tohoto cíle jsem použil technologie zpracování webu napsané v PHP. Komplikace doprovázející automatické zpracování webových stránek byly vyřešeny techonologí Apache Kafka a jejími schopnosti škálování procesů. Modularita platformy byla dosažena pomocí architektury microservices a Docker containerization. Práce umožňuje jedinečný způsob, jak hledat potenciální kriminální aktivity, které se odehrály mimo rámec blockchain, pomocí webové aplikace pro správu platformy a vyhledávání v extrahovaných datech. Vytvořená platforma zjednodušuje přidávání nových, na sobě nezávislých modulů, kde Apache Kafka zprostředkovává komunikaci mezi nimi. Výsledek této práce může být použit pro detekci a prevenci kybernetické kriminality. Uživatelé tohoto systému mohou být orgány činné v trestním řízení nebo ostatní činitelé a uživatelé, zajímající se o reputaci a kreditibilitu kryptoměnových adres.

The problematics of gigabit optical networks as well as web technologies suitable for a web tool implementation were studied within this thesis. An experimental web application for monitoring GPON frames is developed based on the proposed system architecture. The frontend is implemented using ReactJS and the Tornado web framework is used for backend implementation. Data for analysis are read from the stream using the Kafka platform.

My PhD. thesis "Physiognomy of Writing: In the Folds of Literary Ornament" deals with the relation between literature and ornament. It interconnects the sphere of literary history and literary theory with that of visuality. Ornament is analyzed and interpreted as a theoretical figure which allows an examination of literature from the point of view of its visuality and its movement. This approach, elaborated and applied here, labeled "physiognomy of writing", offers a possibility of a visual reading of literature; it represents a way to read literary texts not only in terms of their meaning and message, but also from the point of view of their visual and figural performance. In the first part I outline the concept of ornament in its historical, esthetic and philosophical frames, and explain how to use it in order to interpret literature. The second part offers readings of several 20th century literary texts (Franz Kafka, Rainer Maria Rilke, Hugo von Hofmannsthal, Samuel Beckett, Louis Wolfson and Blanche T.) from the perspective of the affinity of their literary speech and particular ornamental manifestations.

The purpose of this these is to explore Nietzschean values as they appear in three modern allegories: Franz Kafka's The Castle, Albert Camus' The Plague, and Nikos Kazantzakis' Zorba the Greek. The intent is to illustrate Friedrich Nietzsche's three stages of the overman as they apply to Kafka, Camus, and Kazantzakis. (91 pages).

When reading a translated book or a dubbed movie, one might come to wonder if the translation conveys the characters’ personality traits identically to that of the original, and while ‘identical’ may not be achievable, ‘equivalent’ rather may be within the scope of a translator’s capability. Translation between languages as vastly different as Swedish and Japanese, or English and Japanese are bound to face greater difficulties than for example Swedish and English. Japanese dialogue can highlight register and idiosyncratic speech patterns in particularly unique ways. This case study investigates how this is done and handled in both English and Swedish by analyzing the dialogue of the main protagonist Nakata Satoru in the novel Umibe no Kafka by Murakami Haruki. Thus, two questions arise: “What distinguishing elements of Nakata Satoru’s register and formality make his speech unique in the original Umibe no Kafuka?” and “How are the distinct characteristics in the dialogue of Nakata Satoru maintained – or lost in the Swedish and English translations of Umibe no Kafuka?”. In pursuit of an answer to these questions, the original copy of Umibe no Kafuka, the English translation (Kafka on the Shore), and the Swedish translation (Kafka på Stranden) were analyzed and all sentences spoken by Nakata in chapters 6,16 and 20 were recorded and compared to the ST – or source text. The study ultimately found that the distinct characteristics in Nakata’s speech were many times in the English and Swedish translations ignored and that Nakata’s soft spoken, understanding tone was often overlooked in order to allow for the translation to flow naturally.
