The focus of this work is to determine the stress of the crank mechanism of the inverted piston aircraft engine Walter Mikron III C UL from the manufacturer PARMA - TECHNIK, s.r.o. The main method of calculation is the numerical finite elements method using the program ANSYS Workbench, the module Static structural and Transient structural. The approximate indicated cylinder pressure during the duty cycle was determined in the GT-SUITE software. The partial goals are to propose possible modifications in the construction of the crank mechanism and to state the possible power reserves of the engine. The diploma thesis also briefly summarizes the history and development of aircraft piston engines from the company Walter, which developed the engine, and the line of Walter Mikron engines.

The issue of the thesis is a construction of the Radejčín highway tunnel. Project contains all of the stages of construction. The total budget and time schedule were made for complete structure. The technological instruction was made for secondary lining of the tunnel. There is also a plan of security instruction, the list of risks on construction site, suggestion of fixed job contract, the plan of controlls and exams for making invert and upper vault of secondary lining. Another part is the project of construction site with three different drawing of construction sites and text part. The list of machines and devices is for the complete construction. It was added also a chosen construction details and evaluation of geotechnical monitoring.

Dans la deuxième moitié du XIXe siècle, la médecine génésique et la psychiatrie s’intéressent à l’homosexualité, appelée inversion sexuelle à l’époque. Les médecins tentent de comprendre cette tare qui ronge la société. C’est pourquoi ils ont recueilli plusieurs témoignages provenant de ceux qu’ils considéraient comme « malades » pour valider leurs thèses scientifiques. Parmi plusieurs documents de nature autobiographique, le Roman d’un inverti-né (1889) et la Suite du roman d’un inverti-né (1896) sont particuliers, adressés sous l’impulsion de leur auteur à un romancier naturaliste, Émile Zola, et à un médecin, le Dr Laupts. Publiées dans des revues médicales (les Archives d’anthropologie criminelle) et dans un recueil (Tares et poisons), ces lettres ont été lues et analysées en tant que cas médical, autobiographie ou roman. Ces documents n’ont curieusement pas été encore lus comme appartenant au genre de la correspondance, important au XIXe siècle : c’est cet oubli révélateur que ce mémoire cherche à combler. Après un récapitulatif des différentes éditions (chapitre 1), les caractéristiques épistolaires seront examinées (chapitre 2). Les travaux de Brigitte Diaz (2002) et de Judith Lyon-Caen (2006) seront exploités pour souligner l’utilisation par l’auteur du Roman d’un inverti-né des codes épistolaires et de l’univers romanesque zolien. Enfin, l’analyse de l’histoire d’amour entre l’auteur des lettres et le sergent est au cœur du dernier chapitre qui accorde une attention particulière à la manière dont l’épistolier narre ce récit de l’amour entre hommes, en utilisant des codes érotiques et initiatiques. Ainsi, l’originalité du Roman d’un inverti-né et de la Suite du roman d’un inverti-né réside à la fois dans l’histoire particulière de sa publication, dans la nature ambivalente de son genre épistolaire et dans l’histoire d’amour, narrée à un médecin et un écrivain. C’est cette triple originalité qui est étudiée dans ce mémoire. / In the second half of the Nineteenth century, psychiatrists and doctors studied homosexuality, male and female inverts. They tried to understand this bane that afflicts society. Hence, they collected multiple testimonies from those they considered “sick” to validate their scientific theories. Amongst these numerous autobiographic documents, the Novel of an Invert (1889-1896) is the most peculiar. While most of these documents exist under the impulse of doctors and judges, this one was sent to naturalist novelist Émile Zola by a young man. Published in medical journals (the Archives d’anthropologie criminelle) and books (Tares et poisons), the literary genre of this text has been distorted; instead of being called letters, this text has been named novel, medical case, autobiography or confession. Peculiarly, these documents were never studied as a correspondence, an important genre in the Nineteenth century. After going through the different editions and modifications of these letters (chapter 1), we examine the epistolary characteristics of this text (chapter 2). To do so, we used Brigitte Diaz’s (2002) works, along with those of Judith Lyon-Caen (2006), underlining the use by the writer of both epistolary codes and the zolian universe. Finally, the last chapter focuses on the love story between the Italian and the sergeant, with a particular attention to the way the letter writer uses erotic and ritualistic codes to narrate the story. The Novel of the Invert’s originality resides in the peculiar publication history, in the ambivalence of its genre and in the narration of a love story to a novelist and a doctor. This thesis shall study this triple originality.

Indiana University-Purdue University Indianapolis (IUPUI) / The recording and processing of bioelectric signals over the decades has led to the development of many different types of analog filtering and amplification techniques. Meanwhile, there have also been many advancements in the realm of digital signal processing that allow for more powerful analysis of these collected signals. The issues with present acquisition schemes are that (1) they introduce irreversible distortion to the signals and may ultimately hinder analyses that rely on the unique morphological differences between bioelectric signal events and (2) they do not allow the collection of frequencies in the signal from direct-current (DC) to high-frequencies. The project put forth aims to overcome these two issues and present a new scheme for bioelectric signal acquisition and processing. In this thesis, a system has been developed, verified, and validated with experimental data to demonstrate the ability to build an invertible universal amplifier and digital restoration scheme. The thesis is primarily divided into four sections which focus on (1) the introduction and background information, (2) theory and development, (3) verification implementation and testing, and (4) validation implementation and testing. The introduction and background provides pertinent information regarding bioelectric signals and recording practices for bioelectric signals. It also begins to address some of the issues with the classical and present methods for data acquisition and make the case for why an invertible universal amplifier would be better. The universal amplifier transfer function and architecture are discussed and presented along with the development and optimization of the characterization and the inversion, or restoration, filter process. The developed universal amplifier, referred to as the invertible universal amplifier (IUA), while the universal amplifier and the digital restoration scheme together are referred to as the IUA system. The IUA system is then verified on the bench using typical square, sine, and triangle waveforms with varying offsets and the results are presented and discussed. The validation is done with in-vivo experiments showing that the IUA system may be used to acquire and process bioelectric signals with percent error less than to 6% when post-processed using estimated characteristics of and when compared to a standard flat bandwidth high-pass cutoff amplifier.

This project deals with solving differential equations. The aim is find the correct algorithm transforming differential equations of higher order with time variable coefficients to equivalent systems of differential equations of first order. Subsequently verify its functionality for equations containing the involutioin goniometrical functions and finally implement this algorithm. The reason for this transformation is requirement to solve these differential equations by programme TKSL (Taylor Kunovský simulation language).
