In this thesis, we address the problem of service function chaining in a network. Currently, problems of chaining services in a network (i.e. service function chaining) can be broadly categorised into middlebox placement in a network and packet steering through middleboxes. In this work, we present a packet steering approach - One Pass Packet Steering (OPPS) - for use in multi-subscriber environments, with the aim that subscribers having similar policy chain composition should experience the same network performance. We develop and show algorithms with a proof of concept implementation using emulations performed with Mininet. We identify challenges and examine how OPPS could benefit from the Software Defined Data Center architecture to overcome these challenges. Our results show that, given a fixed topology and different sets of policy chains containing the same middleboxes, the end-to-end delay and throughput performance of subscribers using similar policy chains remains approximately the same. Also, we show how OPPS can use a smaller number of middleboxes and yet, achieve the same hop count as that of a reference model described in a previous work as ideal, without violating the subscribers' policy chains.

This thesis analyzes the incomplete exchange rate pass-through effect on Mongolian economy and its implication on monetary policy under foreign and domestic shocks. The analysis is carried out in a small open economy New Keynesian DSGE model proposed by Monacelli (2005), where incomplete exchange rate pass-through is introduced via nominal rigidities on import prices. In order to accomplish the goal, we firstly derive the solutions of the model, calibrate the parameters, and finally simulate the impulse responses. Moreover, SVAR estimation is achieved to estimate the pass-through. Four main results are obtained. First, the exchange rate pass-through into import price and inflation is 0.69% and 0.49% respectively in short run, implying incomplete pass-through in Mongolia. Second, the exchange rate acts as a shock absorber for domestic productivity and foreign demand shock, but as a shock amplifier for domestic demand shock. Third, in case of incomplete pass-through the central bank of Mongolia is required to adjust the nominal interest rate more under the productivity shock, but less for the domestic and foreign demand shock. Finally, deviations from the law of one price contributes considerably to the variability of the output gap under the low pass-through. Therefore, considering incomplete pass-through in...

Title: Success rate monitoring of the selected volleyball spiker game moves in the male extraleague. Aim: The aim of the thesis is to find out the success of the players in the hitter's position in the best eight teams of the men's volleyball extraleague on the pass and on the attack.

This diploma thesis deals with adjusting the reverberation time of enclosed spaces. It is divided into two thematic areas. The first thematic area deals with active systems that adjust the reverberation time, with a stronger focus on usage of reverberators to simulate secondary spaces. The second thematic area is the implementation of reverberators and their fundamental building blocks in Matlab.

The master thesis deals with the attack "‘pass the hash"’ on high privileged accounts. Within the theoretical part is discussed creating hashes and its use. Next is a descrip- tion of the authentication in Windows operating system. There are also pointed out weaknesses in the design of authentication mechanisms. The last part deals with the individual attack and security options for mitigating the impacts. In the practical part are tested available tools for retrieving hashes from the files of the operating systems and tools which allow the attack itself. The output of this section is selection of the appropriate tools to demonstrate the attack in a proposed real environ- ment. The last topic is about designing the experimental environment, demostration of the attack with the possibility of getting through the network. The last steps deal with mitigating the impact of the attack.

Within modern frequency structures, the filter frequency region of up to 10 MHz constitutes a promising research topic that currently attracts intensive attention of specialists interested in the problem. The main reason of this fact consists in that the rapid development of modern technology allows the production of innovated structures of the analog frequency filters required in the defined band. In this context, however, it is also necessary to refine the methods applied in the synthesis and optimization of these structures; such improvement should be carried out with respect to fundamental properties and usability of today's active elements (operational amplifiers with voltage feedback whose Gain Bandwidth Product ranges within units of GHz, operational amplifiers with current feedback, conveyors, transimpedance operational amplifiers). In this thesis, active blocks of synthesis inductors (SIs) and frequency dependent negative resistors (FDNRs) are examined in detail, and the author provides novel formulas to define the basic parameters of the dual circuits. Due emphasis was placed on optimizing the basic building blocks of the second order and defining the variation of their properties caused by the addition of modern active elements. The blocks were analyzed and modified in view of their possible use in higher-order circuits. For active filters of a higher order, simulations were performed to indicate the actual sensitivity of the cascade and non-cascade ARC structures. The following phase of the research comprised mainly the designing of several filters, and this activity was further completed with the verification of the methodology for the synthesis and optimization of higher-order loss ladder filters with modern active blocks. Special attention was paid also to the methods enabling the optimization of such filters, which are invariably based on RLC prototypes. In order to verify the theoretical conclusions, the author materialized a large number of sample optimized filters and measured their parameters. The closing section of the thesis describes the use of the filters in specific applications.

This thesis deals with fully differential and pseudo-differential frequency filters. Significant emphasis is placed on the characteristics of common-mode signal. Further, the text deals with the design issue of fully-differential structure and transformation of non-differential to pseudo-differential structures. In the thesis one non-differential structure, one fully-differential and three pseudo-differential structures are proposed, one of them working in current mode. The thesis also describes the analysis from the perspective of non-ideal properties of the active element of two circuit solutions, which is trying to find the optimal solution. In each case, functionality of new solutions is verified by simulations and in several cases also by experimental measurement.

TESIS PARA OPTAR AL GRADO DE MAGISTER EN ANÁLISIS ECONÓMICO / En los últimos quince años, tanto las autoridades de libre competencia como la literatura han entregado una mayor importancia a la incorporación del pass-through en los casos de colusión. En la estimación de pass-through, varios artículos han expuesto diferentes sesgos a los que se incurre si ésta se estima de forma reducida (estimación más común en la literatura para el pass-through). Esta tesis busca reafirmar la importancia de incluir las estimaciones de pass-through con motivo de estimar los perjuicios en colusión e inspeccionar parte de los sesgos que ocasiona la estimación en forma reducida. En específico, se revisa estos sesgos en un caso aplicado en Chile, investigando en profundidad asimetrías en la estimación de pass-through. Las contribuciones de la investigación se basan en primer lugar, en aportar a la discusión del país sobre un tema que no es analizado localmente. El segundo aporte se basa en observar asimetrías de pass-through en las respuestas de los competidores gracias a un shock heterogéneo en los costos marginales. Para evaluar lo anterior, se utilizan técnicas comúnmente utilizadas en la organización industrial empírica, esto es: estimar la demanda en el mercado final, recuperar los costos marginales y, realizar diferentes contrafactuales suponiendo variados shocks. Los resultados permiten identificar que el efecto pass-through es relevante para evaluar los perjuicios en colusión y, que existe gran heterogeneidad en las respuestas que causa un shock en los costos. El resultado más importante muestra que si hay un shock en costos específico para una marca, solamente los productos con mayor sustitución cambian sus precios finales en la misma dirección que lo realiza la marca afectada, mientras que los productos que no son sustitutos cercanos mantienen sus precios. La heterogeneidad de los shocks y de las respuestas no puede capturarse con estimaciones de forma reducida, esto provoca que los perjuicios estimados, en la mayoría de los casos, se alejen de los reales.

Cette thèse met en évidence l’aspect macroéconomique du degré de report du taux de change sur les prix dans la zone euro. Nous utilisons un large éventail de méthodes économétriques récentes afin de fournir des mesures robustes sur la transmission du taux change ainsi que sur ses déterminants macroéconomiques. Notre recherche révèle le rôle prépondérant des facteurs macroéconomiques dans le déclin récent du degré de report. Une conséquence directe de ce résultat est que la baisse du taux de transmission du change n’est pas nécessairement un phénomène structurel, et il peut être ainsi résolu par des politiques macroéconomiques conjoncturelles. Par exemple, l’adoption de régimes de politique monétaire plus crédibles avec l’engagement de maintenir une inflation faible joue un rôle important dans la réduction de la sensibilité des prix aux variations du change. Ceci est particulièrement valable pour les pays dont les politiques macroéconomiques sont historiquement laxistes. Ainsi, la poursuite de politiques économiques solide et lisible au sein de l’UEM peut être un outil efficace pour réduire le degré de report du taux de change / This thesis highlights the macroeconomic aspect of the exchange rate pass-through to domestic prices in the euro area countries. We use a wide range of up-to-date econometric methods in order to provide robust measures of the rate of pass-through as well as to shed further light on its macro determinants. The main finding of our research is the prominent role of macroeconomic forces in driving the recent declin of the transmission of currency movements. A direct consequence of this result is that the lowering in the rate of pass-through is not necessarily a structural phenomenon and it may be solved via macroeconomic policies. For instance, the shift to a more stable monetary policy conditions with credible and anti-inflationary regime would reduce the sensibility of prices to exchange rate changes. This is especially true for countries with historically poor macroeconomic policies. Thus, a better macroeconomic management with a sounder set of policies within the EMU may be an effective tool for reducing the degree of pass-through
