Případová studie sociálně vyloučené romské lokality v Litvínově - Janově a návrhy řešení / Case Study of Socially excluded locality in Litvínov - Janov and possible solutions

Vinkler, Antonín January 2014 (has links)
This diploma thesis is focused on issues of socially excluded Romany locality in Litvínov - Janov. The problematic situation is described in the thesis. There is a higher number of socially handicapped people with a wide range of social problems like unemployment, insolvency, occurrence of socio-pathological phenomena including criminal behaviour in this locality. The occurrence of socio-pathological phenomena within the socially handicapped people causes conflicts with other residents living in the locality. The diploma thesis also focuses on the precautions and policies made by the city of Litvínov to solve such problematic situation. Each precaution is subsequently described. Furthermore, there is an evaluation of these precautions by means of monitoring social indicators. In result, it is possible to say that there are no signs of distinctive improvement of the situation in the locality. In the conclusion, further precautions are recommended for finding a solution to this problematic situation in the housing estate. The recommended precautions arise from the analysis executed in the locality Janov and from precautions realised by the city of Litvínov.

Sensitivity of Aeroelastic Properties of an Oscillating LPT Cascade

Glodic, Nenad January 2013 (has links)
Modern turbomachinery design is characterized by a tendency towards thinner, lighter and highly loaded blades, which in turn gives rise to increased sensitivity to flow induced vibration such as flutter. Flutter is a self-excited and self-sustained instability phenomenon that may lead to structural failure due to High Cycle Fatigue (HCF) or material overload. In order to be able to predict potential flutter situations, it is necessary to accurately assess the unsteady aerodynamics during flutter and to understand the physics behind its driving mechanisms. Current numerical tools used for predicting unsteady aerodynamics of vibrating turbomachinery components are capable of modeling the flow field at high level of detail, but may fail in predicting the correct unsteady aerodynamics under certain conditions. Continuous validation of numerical models against experimental data therefore plays significant role in improving the prediction accuracy and reliability of the models.   In flutter investigations, it is common to consider aerodynamically symmetric (tuned) setups. Due to manufacturing tolerances, assembly inaccuracies as well as in-service wear, the aerodynamic properties in a blade row may become asymmetric. Such asymmetries can be observed both in terms of steady as well as unsteady aerodynamic properties, and it is of great interest to understand the effects this may have on the aeroelastic stability of the system.   Under certain conditions vibratory modes of realistic blade profiles tend to be coupled i.e. the contents of a given mode of vibration include displacements perpendicular and parallel to the chord as well as torsion of the profile. Current design trends for compressor blades that are resulting in low aspect ratio blades potentially reduce the frequency spacing between certain modes (i.e. 2F &amp; 1T). Combined modes are also likely to occur in case of the vibration of a bladed disk with a comparatively soft disk and rigid blades or due to tying blades together in sectors (e.g. in turbines).   The present investigation focuses on two areas that are of importance for improving the understanding of aeroelastic behavior of oscillating blade rows. Firstly, aeroelastic properties of combined mode shapes in an oscillating Low Pressure Turbine (LPT) cascade were studied and validity of the mode superposition principle was assessed. Secondly, the effects of aerodynamic mistuning on the aeroelastic properties of the cascade were addressed. The aerodynamic mistuning considered here is caused by blade-to-blade stagger angle variations   The work has been carried out as compound experimental and numerical investigation, where numerical results are validated against test data. On the experimental side a test facility comprising an annular sector of seven free-standing LPT blades is used. The aeroelastic response phenomena were studied in the influence coefficient domain where one of the blades is made to oscillate in three-dimensional pure or combined modes, while the unsteady blade surface pressure is acquired on the oscillating blade itself and on the non-oscillating neighbor blades. On the numerical side, a series of numerical simulations were carried out using a commercial CFD code on a full-scale time-marching 3D viscous model. In accordance with the experimental part the simulations are performed using the influence coefficient approach, with only one blade oscillating.   The results of combined modes studies suggest the validity of combining the aeroelastic properties of two modes over the investigated range of operating parameters. Quality parameters, indicating differences in mean absolute and imaginary values of the unsteady response between combined mode data and superposed data, feature values that are well below measurement accuracy of the setup.   The findings of aerodynamic mistuning investigations indicate that the effect of de-staggering a single blade on steady aerodynamics in the cascade seem to be predominantly an effect of the change in passage throat. The changes in steady aerodynamics are thereby observed on the unsteady aerodynamics where distinctive effects on flow velocity lead to changes in the local unsteady pressure coefficients. In order to assess the overall aeroelastic stability of a randomly mistuned blade row, a Reduced Order Model (ROM) model is introduced, allowing for probabilistic analyses. From the analyses, an effect of destabilization due to aero-asymmetries was observed. However the observed effect was of moderate magnitude. / <p>QC 20130610</p> / Turbokraft

Interpretatio Romana : En analys av De Bello Gallico och Germania / Interpretatio Romana : A analysis of De Bello Gallico and Germania

Palmgren, Filip January 2023 (has links)
Uppsatsen utforskar användandet av interpretatio romana i de romerska verken De Bello Gallico och Germania. Genom olika exempel diskuterar studien också huruvida begreppet även kan appliceras på andra aspekter inom det romerska samhället utöver religion. Begreppets roll inom den romerska historieskrivningen och dess bidrag till kulturell appropriering av rum kommenteras slutligen. / The paper explores the use of interpretatio romana in the Roman works De Bello Gallico and Germania. Through various examples, the study also discusses whether the concept can also be applied to other aspects of Roman society besides religion. The role of the concept in Roman historiography and its contribution to the cultural appropriation of space is finally commented on.

Amuletter i antikens Rom : En forskningsstudie om bullae / Amulets in ancient Rome : An research study on bullae.

Yang, Yennifer(ShiHan) January 2022 (has links)
In the ancient world, magic and magical practice was in fact hugely common between people and within the society, different types of magical material has been proved to be importent instrument during those mysterious events. But how we see those ancient materials and how we read them is still one of the key questions that we cannot answer with our modern understanding. Yet, it is not totally impossible to try to solve this type of question. This study will be concerned with ancient amulets from the Roman world, and the time period will draw on the imperial period in ancient Rome. The amulet can be categorized into different types, depending on what subject and motives they are focusing on, for example, amulet to protect mothers during the childbirth is one of the common type of protecting amulet for women, because mortality rate for both mother and the child was extremely high during the ancient period; there’s even amulets that protect people from evil spirits, such as the evil eye, which will be explained in one of the chapter. In this case, this study will be focusing on one type named “bullae”, which is speculated to be used only by roman children. It will be interpret with ancient literature and modern researches, so we may be able to investigate a part of how and why ancient people were using magical materials in their common life, also what it could tell us about the society of ancient Rome, and at last, in which ways do we know that this type of thing can be recognize as “amulet” instead of other types of jewellery.
