Měření ovality extrudovaného vlákna pomocí tří kamer / Ovality measurement of extruded fiber using three camerasLoučka, Pavel January 2019 (has links)
One of the important parameters observed during extruded fibre fabrication is its diameter. The diameter can be measured with a single scanning camera assuming that the fibre section has a circular shape. As proved in practice, another important parameter is ovality, that is the rate of fibre flattening. This paper assumes that the fibre section shape is elliptical. In such a case, at least three different views on examined fibre are needed. Mathematical part of this paper is concerned with analytical description of fibre ovality measurement using two different approaches based on the knowledge of linear algebra, projective geometry and conic sections theory. Main goal of this paper is thus to use both mathematical theory and image analysis methods for ovality and diameter determination. Precise calcluation of such quantities is, however, conditioned on precise camera system calibration, which is described in the paper as well. Additionally, the work contains a brief mention of technical realization of ovality measurement and its possible difficulties.

Tic-tac... Explorer les perceptions de femmes qui vivent un échec du déclenchement du travailRioux, Emilie S. 08 1900 (has links)
Le déclenchement du travail est une procédure obstétricale qui consiste à provoquer le travail afin que la femme puisse vivre un accouchement vaginal dans les 24 à 48 heures suivant l’initiation de la procédure (Leduc et al., 2013). Cependant, le déclenchement du travail peut ne pas fonctionner entraînant la nécessité de procéder à un accouchement par césarienne après un travail d’une durée de plus de 24 heures. Cette étude qualitative visait à explorer l’expérience de femmes qui ont vécu un échec du déclenchement du travail résultant en une césarienne non planifiée. Cette étude a été menée auprès de 6 femmes durant leur séjour hospitalier post-partum. Les données ont été obtenues à l’aide d’un questionnaire sociodémographique, du dossier médical des participantes et d’un entretien semi-dirigé. Les entretiens semi-dirigés ont été enregistrés, avec l’accord des participantes, puis transcrits et analysés selon l’approche d’analyse thématique de Braun, Clarke, Hayfield et Terry (2019). Cinq thèmes et 12 sous-thèmes ont émergé de l’analyse thématique permettant de mieux saisir l’expérience des femmes vivant un échec du déclenchement du travail résultant en une césarienne. Les thèmes : Les attentes envers l’expérience, Le soutien reçu, La qualité et quantité de l’information reçue ainsi que Le sentiment de contrôle envers l’expérience semblent influencer la satisfaction ou l’insatisfaction de la participante envers son expérience et contribuent au thème global de l’Expérience globale de l’échec du déclenchement du travail résultant en une césarienne. Les infirmières ont un rôle important afin de communiquer l’information aux patientes et de les soutenir quant au déclenchement du travail leur permettant de mieux gérer leurs attentes et exercer le contrôle désiré envers leur expérience. / Induction of labor is an obstetric procedure which consists of inducing labor so that women can experience a vaginal birth within 24 to 48 hours after the initiation of the procedure (Leduc et al., 2013). The induction of labor may not work resulting in the need for a caesarean delivery after lasting more than 24 hours. This qualitative study aimed to explore the experience of women who had experienced labor induction failure resulting in an unplanned caesarean section. This study was conducted with 6 women in the postpartum unit during their hospitalisation. Data were collected from a socio-demographic questionnaire, the participants’ medical chart as well as a semi-structured interview. After participants’ consent, the semi-structured interviews were recorded, transcribed, then analysed using the Braun, Clarke, Hayfield and Terry (2019) thematic analysis approach. Five themes and 12 sub-themes emerged to better capture the experience of women experiencing labor induction failure resulting in a caesarean. Four themes: Expectation of Labor and Delivery: Managing Expectations, Antepartum and Intrapartum Support Received, Comprehensive Information Needed, and Feeling in Control of the Experience emerged as influencing the participant's satisfaction or dissatisfaction towards their Global Experience of a Failed Induction of Labor Resulting in a Ceserean Section. Nurses have a strategic role and are key support professionals in communicating information and supporting women during induction of labor, allowing them to better manage their expectations and have the desired level of control over their experience.

Měření elektrických veličin v distribučních sítích 22 kV a 0,4 kV s disperzními zdroji / Monitoring in Middle- and Low-Voltage distribution systems penetrated by distributed generationKolacia, Tomáš January 2015 (has links)
This thesis concerns monitoring in Middle- and Low-Voltage distribution systems penetrated by distributed generation. Monitoring itself means measuring voltages and power flows and sending relevant data to the supervisory system. The first part of the thesis describes distribution systems with differences between individual voltage levels. The following chapter is focused on consequences of high share of renewable energy sources in distribution systems. Most of the problems are partially resolved by technical conditions for connection of the new power sources. However, difficulties with voltage regulation and uncontrolled power flows to higher voltage levels remain. These are the reasons for measuring voltages and currents in medium voltage networks. Second to last subhead of this chapter is dedicated to possible benefits of monitoring. The fourth part of the thesis deals with voltage and current sensors with their advantages and disadvantages. The best suitable devices are chosen in the end of the chapter. It is crucial to mention that sensors are only part of measuring system. Analog outputs from current or voltage transformers need to be converted to digital signal and further processed. After that required quantities are finally sent. Properties of these circuit cards are described in the sixth chapter. Following part aims to define a certain key that will determine the suitable locations for installation of the measurement. The final part of the thesis compares measured voltages and power flows from real 22 kV network with calculated values from computer program PAS DAISY Bizon.
