Silní a slabí podle Římanům 14-15 / The Strong and the Weak in Romans 14-15

Majtán-Černák, Marek January 2017 (has links)
The present diploma thesis is an exegetical attempt to interpret Paul's parenesis in his Letter to the Romans 14,1-15,13. It tries to find answers to the following questions: Who are the "strong in faith" (15:1)? Who are the "weak in faith" (14:1)? What "day" is meant in chapter 14:5? What kind of dietary restrictions are in the background of 14:2? What is the solution that Paul suggests? The analysis has led to the following conclusions: Paul is trying to resolve a particular dispute between two groups of believers in Rome. The "weak" probably had a problem with the "strong" eating the meat and drinking the wine defiled with idolatry (14:21) and not keeping fasting days, or certain Jewish feast days (14:3). So, the "weak" may be identified as the Jewish Christians and the "strong" with the Christians of gentile origins. Paul tries to move both groups away from judging each other (14:3) to respect the opinion of the other group (14:4) and leads them above all to mutually build loving relationships to each other (14:19). Key words: weak in faith, strong in faith, day, food, dietetary restriction, Lord, Christ, Kingdom of heaven

A Study of Liquid Bridge Dynamics: an Application to Micro-Assembly/Une Etude de la Dynamique du Pont Liquide: une Application au Micro-Assemblage

Valsamis, Jean-Baptiste 31 May 2010 (has links)
Micro-assembly processes suffer from some breaches due to the continuing trend towards an increase in the production capabilities as well as in the size reduction of the components manipulated. Usual manipulating schemes have reached their limit and capillary forces constitute a valuable alternative strategy. The goal of this work is to describe the dynamics of liquid bridges in the application of micro-assembly processes. The description is obtained using the Kelvin-Voigt model, with a spring, a damper, and a mass connected in parallel, supported by numerical simulations, analytical approximations and experiments. The works is divided into three parts. First we present important aspects of microfluidics, as well as the constitutive equations and an overview of numerical approaches used to describe fluid flow problems with moving interfaces. The second part is devoted to the capillary rise case, intended to validate and to compare the numerical approaches to analytical laws and experimental results. The implementation of the slipping and the dynamic contact angles is discussed. The last part focuses on the dynamics of the liquid bridge. The liquid bridge is confined between two circular and parallel plates and presents an axial symmetry. The description reveals that the stiffness depends on the surface tension and on the shape of the air/liquid interface, the damping coefficient depends on the viscosity and the volume of liquid and the equivalent mass depends on the density and the volume.

Untersuchungen zur Selektivität unterschiedlich substituierter Iminodiessigsäure-Ionenaustauscher gegenüber zweiwertigen Metallionen / Research into the selectivity of iminodiacetat-ion-exchangers compared to bivalent metals

Niehus, Christina January 2007 (has links)
Zur selektiven Entfernung von Schwermetallen aus industriellen Abwässern und Prozesslösungen der metallverarbeitenden Industrie werden synthetische metallkomplexierende funktionelle Polymere – mit Iminodiessigsäure (IDE) als aktive Spezies – seit Jahren erfolgreich zur Eliminierung störender Kationen eingesetzt. Ständig steigende Anforderungen an die Qualität der aufzubereitenden Wässer verlangen nach leistungsfähigen Selektivaustauschern, die den Erhalt der Eigenschaften von Prozesslösungen (z. B. pH-Wert, Salzgehalt) ermöglichen. Ziel der Untersuchungen war es, die strukturellen Matrixeinflüsse auf Beladung, Kapazität, Selektivität und Kinetik durch Variation der Matrix und der experimentellen Bedingungen näher zu untersuchen. Auf Basis einer monodispersen Erstsubstitution eines Styren-Divinylbenzen-Copolymerisates wurde durch gezielten Einbau funktioneller Gruppen – Synthese mit differenziertem Substitutionsgrad (TK/N 1-2) – versucht, systematisch den Einfluss des Substitutionsgrades der Matrix auf die Eigenschaften der Ionenaustauscher zu analysieren. Methodisch geordnet wurden zunächst die Versuche nach dem Batch- und anschließend nach dem Säulenverfahren durchgeführt und parallel dazu die Matrix charakterisiert. Das Verhalten der funktionellen Ankergruppen in Abhängigkeit vom pH-Wert der Lösung (pH-Bereich 2 - 5) wurde untersucht, der optimale Anreicherungs-pH-Wert, die maximale Beladung (Kapazität) und Selektivität der unterschiedlich substituierten Proben für die Schwermetall-Ionen Cu, Zn, Ni, Cd, Pb und Co ermittelt. Den statischen Versuchen folgten dynamische Untersuchungen im Säulenverfahren. Ziel war die Ermittlung des Durchbruchverhaltens und der Durchbruchkapazität bei optimalem pH-Wert in Abhängigkeit vom Substitutionsgrad gegenüber den Einzelmetallionen (Cu, Ni, Zn) und ausgewählten Paaren (Cu/Ni, Cu/Zn, Ni/Zn). Alle Ionenaustauscher wurden ausschließlich in der Ca-Form eingesetzt. / Selective ion exchange offers a good solution for cleaning many waste streams. The aim of this study was to develop selective ion exchange materials for effective and economical applications in waste water treatment. The investigation of chelate resins is based on iminodiacetate with different secondary substitution (degree of substitution TK/N 1 - 2, from aminoacetic acid to iminodiacetate as functional group). As comparison the weak acid resin Lewatit TP 207 was used. The research focused on the application of selective ion exchange resins for waste effluents to ascertain the feasibility of a selective ion exchange process employing chelating cation exchangers for heavy metal removal. The metals of interest were copper (Cu), zinc (Zn), nickel (Ni), cobalt (Co), lead (Pb) and cadmium (Cd) and the resins appointed in the Ca-form. The batch operation was conducted to determine the equilibrium data and the operating resin capacity, one of the most important properties. The main equilibrium parameter affecting the ion exchange was the pH value (array 2-5). The best accumulation pH value was obtained using pH 5 for all metals. The only exception was lead with pH 3. After determining the viability of the different resins with batch systems, this study has focused on the column mode experiments. They were generated for the selected resins in the continuous ion exchange process which are essentially reserved for industrial applications. A practical application of the breakthrough curves is the determination of the breakthrough time which helps to find the best operating conditions.

Mohamed, Hussein, Oyoko, Millicent January 2008 (has links)
Abstract The research investigates the sustainability and effectiveness of the projects that are funded by the Swedish International Development Agency (SIDA) in Kenya. SIDA is the Swedish central state agency responsible for planning, implementing and managing Aid. The research applies both the absorptive capacity and the institutional theory to explain the phenomenon of Aid projects failures in Kenya. The research has used a qualitative research method, a literature study that blend with structured open-ended interview questions which we have formulated. By studying the various Actors involved in Swedish foreign Aid, their operations and deliverance, it will facilitate our study to establish the major causes and origins of development projects failures in Kenya. The main and current Swedish development goals are “improving the standard of living for poor people”, the sub goals are Economic growth, Economic and social equality, Economic and Political Independence, Democratic Development and Protection of human rights, Sustainable use of natural resources, protection of Environment Conflict management and Security. The reason why Aid projects are not producing the intended results could be divided into two parts; the planning problem that emanate from the donors side. The irony is that development partners are viewed to be aiming at alleviating poverty without proper planning and even their priorities are not always right. The other major reason is attributed to the recipients’ side and could be summarized as lack of democracy, corruption, weak institutions, lack of absorptive capacity and mismanagement.

Inverse Problems in Analytic Interpolation for Robust Control and Spectral Estimation

Karlsson, Johan January 2008 (has links)
This thesis is divided into two parts. The first part deals with theNevanlinna-Pick interpolation problem, a problem which occursnaturally in several applications such as robust control, signalprocessing and circuit theory. We consider the problem of shaping andapproximating solutions to the Nevanlinna-Pick problem in a systematicway. In the second part, we study distance measures between powerspectra for spectral estimation. We postulate a situation where wewant to quantify robustness based on a finite set of covariances, andthis leads naturally to considering the weak*-topology. Severalweak*-continuous metrics are proposed and studied in this context.In the first paper we consider the correspondence between weighted entropyfunctionals and minimizing interpolants in order to find appropriateinterpolants for, e.g., control synthesis. There are two basic issues that weaddress: we first characterize admissible shapes of minimizers bystudying the corresponding inverse problem, and then we developeffective ways of shaping minimizers via suitable choices of weights.These results are used in order to systematize feedback controlsynthesis to obtain frequency dependent robustness bounds with aconstraint on the controller degree.The second paper studies contractive interpolants obtained as minimizersof a weighted entropy functional and analyzes the role of weights andinterpolation conditions as design parameters for shaping theinterpolants. We first show that, if, for a sequence of interpolants,the values of the corresponding entropy gains converge to theoptimum, then the interpolants converge in H_2, but not necessarily inH-infinity. This result is then used to describe the asymptoticbehaviour of the interpolant as an interpolation point approaches theboundary of the domain of analyticity.A quite comprehensive theory of analytic interpolation with degreeconstraint, dealing with rational analytic interpolants with an apriori bound, has been developed in recent years. In the third paper,we consider the limit case when this bound is removed, and only stableinterpolants with a prescribed maximum degree are sought. This leadsto weighted H_2 minimization, where the interpolants areparameterized by the weights. The inverse problem of determining theweight given a desired interpolant profile is considered, and arational approximation procedure based on the theory is proposed. Thisprovides a tool for tuning the solution for attaining designspecifications. The purpose of the fourth paper is to study the topology and develop metricsthat allow for localization of power spectra, based on second-orderstatistics. We show that the appropriate topology is theweak*-topology and give several examples on how to construct suchmetrics. This allows us to quantify uncertainty of spectra in anatural way and to calculate a priori bounds on spectral uncertainty,based on second-order statistics. Finally, we study identification ofspectral densities and relate this to the trade-off between resolutionand variance of spectral estimates.In the fifth paper, we present an axiomatic framework for seekingdistances between power spectra. The axioms requirethat the sought metric respects the effects of additive andmultiplicative noise in reducing our ability to discriminate spectra.They also require continuity of statistical quantities withrespect to perturbations measured in the metric. We then present aparticular metric which abides by these requirements. The metric isbased on the Monge-Kantorovich transportation problem and iscontrasted to an earlier Riemannian metric based on theminimum-variance prediction geometry of the underlying time-series. Itis also being compared with the more traditional Itakura-Saitodistance measure, as well as the aforementioned prediction metric, ontwo representative examples. / QC 20100817

Relationship Status: It's Complicated - The Role of Narcissism in the Development of Relationships Through Facebook

Saad, Michael 13 September 2012 (has links)
The presence of both narcissism and social capital in the digital social networking site Facebook is altering the dynamic of relationship development. Therefore, the central research question directing this study is as follows: What role do narcissistic personality traits play in bridging social capital on Facebook? From this, two sub-questions are raised: 1) What are the motives for users to express narcissistic traits through Facebook? 2) How is narcissistic-motivated activity influencing social capital development through Facebook? Guiding this thesis are concepts of social tie relationships (as they apply to narcissism), and digital social networks. An exploratory study of in-depth interviews was utilized to conduct such research. A key objective in this thesis is understanding motive and purpose for generating social capital in an online environment. The findings from this study suggest Facebook is a facilitator for the expression of narcissistic traits. As a result, this is influencing the disconnected and questionable value of digital social capital.

Detecting and preventing the electronic transmission of illicit images

Ibrahim, Amin Abdurahman 01 April 2009 (has links)
The sexual exploitation of children remains a very serious problem and is rapidly increasing globally through the use of the Internet. This work focuses on the current methods employed by criminals to generate and distribute child pornography, the methods used by law enforcement agencies to deter them, and the drawbacks of currently used methods, as well as the surrounding legal and privacy issues. A proven method to detect the transmission of illicit images at the network layer is presented within this paper. With this research, it is now possible to actively filter illicit pornographic images as they are transmitted over the network layer in real-time. It is shown that a Stochastic Learning Weak Estimator learning algorithm and a Maximum Likelihood Estimator learning algorithm can be applied against Linear Classifiers to identify and filter illicit pornographic images. In this thesis, these two learning algorithms were combined with algorithms such as the Non-negative Vector Similarity Coefficient-based Distance algorithm, Euclidian Distance, and Weighted Euclidian Distance. Based upon this research, a prototype was developed using the abovementioned system, capable of performing classification on both compressed and uncompressed images. Experimental results showed that classification accuracies and the overhead of network-based approaches did have a significant effect on routing devices. All images used in our experiments were legal. No actual child pornography images were ever collected, seen, sought, or used.

Att vänja sig till det svenska språket : studier av en individuell skriftspråklig förändring utifrån Olof Bertilssons kyrkobok 1636-1668

Hellström, Solbritt January 2008 (has links)
On the annexation of Jämtland by Sweden in 1645, Danish clergymen were allowed to remain on condition that they officiated in the Swedish language. This dissertation investigates the changes in the written language of one of these Danish clergymen and is based on the parish register kept by the Rev. Olof Bertilsson between 1636 and 1668. The premise for this study is that individual variations and alterations in written language do not occur arbitrarily, but display systematisation and express social consensus. The analytical basis for this approach is derived from Alexander Zheltukhin’s work on orthographic code theory and employs concepts used in sociolinguistics, but also borrows ideas from theories of mixed languages and second-language learning. Between 1636 and 1646 Olof Bertilsson displays a highly stable orthographic code with few variations. Following his attendance at the Riksdag (the Swedish Parlament) in Stockholm in 1647, a distinct change is evident in his orthography. Changes occur quite early in the spelling of some place-names, personal names and important and frequent ecclesiastical terms. A decisive factor in determining when and how change occurs is his access to examples of Swedish texts. In the last decade of his life, an influx of Swedish clergy, increased contacts with Swedish officials and help from young clergymen with a Swedish education, contribute to a predominance of Swedish forms in Olof Bertilsson’s individual orthographic code.
