The study deals with production technology of “revolver trigger“. Final assembly is short firearm ALFA Steel and its model series of ALFA-PROJ, Ltd company. Introduction submits an explanation of trigger technology suitability. The following analysis describes current manufacturing process, which has manufacturing inaccuracy problem. Furthermore rootcause of manufacturing inaccuracy was determined and analysis of suggestions for changes (including modifications of technological process) was realized. Based on experiment dimensions were measured on provided samples of suggest production in Technical Control Department. Dimensions of triggers manufactured by current production were verified during the experiment too. Results were compared according to the rejects of production. In the final phase of the study manufacturing labor costs were compared for the one piece of trigger with the new suggested technology.

The aim of this thesis named Transforming of the Revolver Revue (1990-2000) and its Critical Analysis is to describe the image and development of the cultural magazine Revolver Revue, including its supplement Kritická Příloha Revolver Revue during the first decade after the 1989 "Velvet revolution". Special attention is given to its literature reviews that largely determined the reception of of the magazine. Because the magazine was strongly influenced by its underground roots and the examined period of 1990s was full of remarkable socio- political changes the historical context, especially the developments of media and literature of that period, is discussed. To get an image of the magazine's role and its transformations as seen from the outside we describe how it was received by the contemporary press. The theoretical part focuses on issues of the conception of the literary criticism, which relates to the search for the role of criticism in the 1990s and it outlines the diversity of different perspectives, concepts and attitudes. The section dedicated to Kritická Příloha includes analysis of a few chosen reviews and aims to explore the form of criticism published in this magazine. The thesis also includes interviews with the chief editor of Revolver Revue Terezie Pokorná, and with Jáchym Topol,...

This diploma thesis addresses the issue of using the evaluation of surface texture in the manufacture of revolver with aplication to a cock. It deals with the detection of imperfections of production operations, the proposal of corrective measures and its implementation. The use of new grinding wheel was chosen as a corrective measure. The Rzmax parameter was used to specify the surface texture after miling and a combination of the Rzmax and Rpmax parameters was used to specify surface texture after grinding.

Resumé The diploma thesis is dedicated to the forms of the Czech underground scene on the basis of the analysis of two samizdat literary journals - Vokno (1979-1989) and Revolver Revue (1985-1989). The thesis studies analogous and distinct tendencies in both magazines which became the platforms of the different underground generations. Vokno is connected with the first underground generation that was formed at the beginning of the 1970s. The second underground generation debuted at beginning of the 1980s and later united around the Revolver Revue magazine. The next part of the diploma thesis focuses on the symptomatic features of the poetics of four central writers that shaped the appearance of the journals. The analysis arises from the texts published in both Vokno and Revolver Revue magazines.

A credit card as a banking product has a dual nature both as a convenient loan and a payment tool. Credit card profitability prediction is a complex problem because of the variety of the card holders' behaviour patterns, a fluctuating balance, and different sources of interest and transactional income. The state of a credit card account depends on the type of card usage and payments delinquency, and can be defined as inactive, transactor, revolver, delinquent, and default. The proposed credit cards profit prediction model consists of four stages: i) utilisation rate and interest rate income prediction, ii) non-interest rate income prediction, iii) account state prediction with conditional transition probabilities, and iv) the aggregation of the partial models into total income estimation. This thesis describes an approach to credit card account-level profitability prediction based on multistate and multistage conditional probabilities models with different types of income and compares methods for the most accurate predictions. We use application, behavioural, card state, and macroeconomic characteristics as predictors. This thesis contains nine chapters: Introduction, Literature Review, six chapters giving descriptions of the data, methodologies and discussions of the results of the empirical investigation, and Conclusion. Introduction gives the key points and main aims of the current research and describes the general schema of the total income prediction model. Literature Review proposes a systematic analysis of academic work on loan profit modelling and highlights the gaps in the application of profit scoring to credit cards income prediction. Chapter 3 describes the data sample and gives the overview of characteristics. Chapter 4 is dedicated to the prediction of the credit limit utilisation and contains the comparative analysis of the predictive accuracy of different regression models. We apply five methods such as i) linear regression, ii) fractional regression, iii) beta-regression, iv) beta-transformation, and v) weighted logistic regression with data binary transformation for utilisation rate prediction for one- and two-stage models. Chapters 5 and 6 are dedicated to modelling the transition probabilities between credit card states. Chapter 5 describes the general model setups, model building methodology such as transition probability prediction with conditional binary logistic, ordinal, and multinomial regressions, the data sample description, the univariate analysis of predictors. Chapter 6 discusses regression estimation results for all types of regression and a comparative analysis of the models. Chapter 7 describes an approach to the non-interest rate income prediction and contains a comparative analysis of panel data regression techniques such as pooled and four random effect methods. We consider two sources of non-interest income generation: i) interchange fees and foreign exchange fees from transactions via pointof- sales (POS) and ii) ATM fees from cash withdrawals. We compare the predictive accuracy of a one-stage approach, which means the usage of a single linear model for the income amount estimation, and a two-stage approach, which means that the income amount conditional on the probability of POS and ATM transaction. Chapter 8 aggregates the results from the partial models into a single model for total income estimation. We assume that a credit card account does not have a single particular state and a single behavioural type in the future, but has a chance to move to any of possible states. The income prediction model is selected according to these states, and the transition probabilities are used as weights for the particular interest rate and non-interest rate income prediction models. Conclusion highlights the contributions of this research. We propose an innovative methodological approach for credit card income prediction as a system of models, which considers the estimation of the income from different sources and then aggregates the income estimations weighted by the states transition probabilities. The results of comparative analysis of regression methods for: i) utilization rate of credit limit and ii) non-interest income prediction, iii) the use of panel data with pooled and random effect for profit scoring, and iv) account level non-binary target transition probabilities estimation for credit cards can be used as benchmarks for further research and fill the gaps of empirical investigations in the literature. The estimation of the transition probability between states at the account level helps to avoid the memorylessness property of the Markov Chains approach. We have investigated the significance of predictors for models of this type. The proposed modelling approach can be applied for the development of business strategies such as credit limit management, customer segmentation by the profitability and behavioural type.

Otto Scheeloch's U.S. Patent No. 134,442 of 1872 describes a unique firearm that uses triangular bullets. The current research effort evaluates the ballistic performance of Otto's disclosure for the very first time. To achieve this goal it was necessary to seek out surviving artifacts and scour the historical record in search of all the parameters needed to meticulously recreate the curious triangular cartridges and the corresponding gun barrel, with its matching twisted triangular bore. Every aspect of the resulting reproduction ammunition was made to be as authentic as possible, including the use of vintage civil war era bullet lead, bullet grease of period recipe, and the correct type of black powder propellant. 3D CAD (SolidWorksTM) was employed in designing the components, while advanced rapid prototyping (FDM & DMLS) techniques and investment casting were used in the physical construction of the ammunition and barrel. The ballistics testing was performed from a shooting rest over a range of 10-feet. Data was obtained for five rounds using a chronograph, paper targets and ballistic gel. The triangular bullets proved to be surprisingly accurate, consistent, and stable in flight. Data was recorded for sectional density, ballistic coefficient, muzzle velocity and energy, group size and penetration.

This Masters thesis examines the production of a revolver frame and the implementation of a new CAM system for the manufacturing process. This thesis contain four parts. The first part is focused on the current manufacturing process. The second part of the thesis consists of a new proposal to use progressive rotary tools and elements of automation for inspection by the Equator Gauging System. The third part proposes a new manufacturing strategy for the revolver frame. At the end of the thesis, the production times of proposed and current technologies are compared.

The goal of this master’s thesis was design of the inspection procedure for hammer and trigger of the specific revolver model. Thesis was developed in cooperation with the manufacturer of the revolvers. The theoretical part deals with the MSA methodology, which is used to assess acceptability of measurement systems. The practical part describes the current measurement system and performs gage repeatability and reproducibility study. It was confirmed that the current measurement system requires improvement. Subsequently coordinate systems were designed, based on functional features of the hammer and trigger. Automated optical measurements, based on the coordinate systems, were performed. The results from these measurements were again assessed by the gage R&R study. The analysis confirmed improvement of acceptability of the designed measurement systems. Based on these results, it is recommended to apply suggested procedures in practice. Results and recommendations of this master’s thesis can contribute to develop metrology in the company and improve the existing measurement system.

Revolver Revue is a cultural periodical magazine founded in 1985. Initially, as a product of Czech underground subculture, of the former communist Czechoslovakia, Revolver Revue was deemed to be illegal samizdat material. After the transformation of the social and political environment in Czechoslovakia, Revolver Revue became a legal publication, and continues to be published today, in the Czech Republic. The following work is a study of Revolver Revue as a social phenomenon in which the author works towards capturing its main defining features and its developments over time, including it's noteworthy changes as well as the continuity which the organization has seen. Also focused upon are the specific social groups related to Revolver Revue, the specific institutions and the interaction of important actors involved, all perceived through a political and historical context. This work is centred around qualitative empirical research based on analyses of interviews and on the study of related documents. The approach taken to this study was heavily influenced by Grounded Theory.

This paper addresses the problem of a failing net debt approach; deposited funds rarely compensate the cost of debt. Venturing into operational credit facilities, the study evaluates the efficiency and feasibility of transitioning into fully cash-free liquidity management. The study takes a holistic approach and evaluates the research questions from the perspective of management through case studies on four smaller Swedish industrial firms. The study finds that there is substantial potential to free up capital; return on equity could have been boosted by an annual 5-10 percent including substantial one-off distributions. The study also concludes that Agency reasons are strong reasons for why firms are carrying material cash reserves. Through qualitative interviews, the study identifies several additional, but not less important, obstacles in the way of a full out cash-free transition. Most significantly, the financial system is not offering fully committed long term operational credit facilities and operating across different jurisdictions complicates the consolidation of liquidity. The study concludes that the matter would not have vast negative implications on real business activities, although further research would be required in regard to an extended debt overhang problem. / Uppsatsen kretsar kring den fallerande logiken med begreppet nettoskuld; tillgodohavanden på bank genererar sällan upp för kostnaden relaterad till motsvarande skuld. Med utgångspunkt i operationella kreditstrukturer utvärderas möjliga effektivitetsvinster och genomförbarheten av en fullständig övergång till kassa-fri likviditetshantering. Studien har ett holistiskt angreppssätt och utvärderar frågeställningarna från ett management-perspektiv genom fallstudier på fyra mindre svenska industriella bolag. Studien finner betydande möjligheter att frigöra kapital; årliga avkastningen på eget kapital hade kunnat öka med 5–10 procent och betydande engångsutdelningar hade varit möjliga. Studien finner vidare att agentteorin är en stark anledning till att bolag bär betydande kassapositioner. Genom kvalitativa intervjuer identifierar studien ytterligare, men ej desto mindre betydande, hinder för en kassa-fri övergång. Mest betydelsefullt, är att nuvarande finansiella system inte erbjuder för syftet fullgoda kreditstrukturer, samt det faktum att företag med verksamhet över olika jurisdiktioner upplever juridiska svårigheter med att konsolidera likviditet. Studien drar slutsatsen att en övergång inte skulle medföra betydande negativa konsekvenser för den operativa affärsverksamheten, men identifierar samtidigt att ytterligare studier skulle vara nödvändiga framförallt kring hur finansiella incitament kopplade till agent-teorins ’debt overhang’ skulle förändras vill en övergång till en fullt garanterad operationell kreditstruktur.
