The thesis deals with analyses of the laboratory symmetrical supplies with adjustable output voltage. It also describes different kinds of current cut-out circuits and several most frequent supply connection schemes. Analyses (simulation program OrCAD) show the characteristics and behaviour of the mentioned supplies. To set the output voltage, operational amplifier structures or linear three-terminal voltage regulator are very often used. The suggested supply was tested and its parameters compared with the simulations. The value of output voltage and current can be controlled with a computer with a USB port. For controlling of the output voltage and current the digital potentiometers were used and controlled by I2C bus.

Accounting terms are very important for every company in the sphere of company finance, accounting terms are claims and accounts payable. The aim of this work was detailed description of claims, then show the control system of the claims of ENVIRO-EKOANALYTIKA and propose improvements to the existing claims management system. The main reasons why claims come into existence are business relations, but they can be caused by provided deposits, loans and bank credits. Claims from business relations are necessary parts of belongings, because every businessman needs goods and services from others. A company can analyse high earnings and profit in accounting but his financial resources can be essentially different. For a company is very important to have a sufficient number of financial resources and to this a company ensures of claims and then restricts entrepreneurial risk. The ensuring of claims means that contractual partner is obliged to realise his account payable. General forms to ensure claims are for example: penal clause, liability, acknowledge a debt, bank quarantee or altitude of debt. We can divide claims in risk claims and abandoned claims. During trading a lot of profits are formed, these profits can be evoked by for example: political or economical events, announcing a financial insolvency or natural catastrophe. Between the most frequent cause of risk claims are mainly the absence of morality in business relations. If the payment of claim is not done until fixed date, the claim gets the bad debt. The only way how to anticipate abandoned claims is, that busines men do not let them come into existence. The proceedings also include claims recovery. The main objective of recovery is to get customers to pay, and as early as possible. Most companies use a standard procedure for recovery, which includes telephone reminders, terminating the supply of credit, written reminders, the transmission of judicial or extrajudicial recovery.

The diploma thesis deals about design of the ARC multifunctional filters using modern functional blocks. These active blocks are for example voltage feedback operational amplifiers (OAs), operational transconductance amplifiers (OTAs), current conveyors (CCIIs) or current mode analog multipliers, current feedback amplifiers (CFAs), integrated circuits with switched capacitors building blocks (SCs) and digital potentiometers. The filters are studied with ideal circuit models and models of third level (3) based on voltage controlled voltage sources, voltage controlled current sources etc. (analog behavioral modelling). The professional macromodels are used for example LT 1364 (Linear Technology), EL 2045 (Intersil), LT 1228 (Linear Technology), LM 13700 (National Semiconductor), EL 2082 (Intersil), AD 844 (Analog Devices) and others. The circuits of the designed filters are simulated in PSpice (OrCAD), parasite effects and effects of the real parts are studied. Tuning and electronic adjusting parameters these filters are discussed and controlled by simulation in PSpice. Properties some simulated circuits are compare with experimental results. In conclusion individual filters are discussed and compared their properties. The constructional details of the some filters are presented at the end of this work.

The diploma thesis deals with analysis, validation, measurement of parameters of the commercially available current multiplies (namely the EL2082 and EL4083) and their applications in practice. Control analysis are carried out in OrCAD PSpice program and compared with values from datasheets. Control analysis are focused on AC and DC characteristics of these active blocks. There are discusses the input impedance, the output impedance, the current gain and the possibility of electronic adjusting. The parameters of the elements were verified by measurements. Proposals for circuit applications (selective circuit, oscillator, frequency filter) with EL2082 and EL4083 are presented and analyzed in the program OrCAD. Three oscillator circuit designs are experimentally tested and the results are compared with the theoretical expectations and simulations in OrCAD. The possibility of electronic control for oscillators is examined. Also the sensitivity and the tolerance analysis are carried out. The constructional details of oscillators are presented at the end of this work.

This master’s thesis deals with the obtuse-angled cone crushers especially about design of the individual parts of the adjustment mechanism. Most space is devoted to functional calculation and subsequent technical construction of the new design of obtuse-angled crusher where the output setting is adjusted using the motion thread and hydraulic locking system for compensating the thread clearance. The parameters are chosen with regard to the already established older types of cone crushers produced by PSP Engineering, a.s. An inseparable part is the calculation verifying the functionality of the motion thread and gearing. Another essential part of this work are stress analysis of the slot adjusting mechanism design using finite element method and considering two states - adjusting of the slot and crushing itself.

Galvanic corrosion is a destructive process between dissimilar metals. The present paper presents a constructed numerical test case to simulate galvanic corrosion of two dissimilar metals. This test case is used to study the accuracy of different implementations to track the dissolving anode boundary. One technique is to numerically simulate a mesh displacement based on the prescribed displacement at the anode boundary. The second method is to adjust only the boundary elements. Re-meshing after a certain number of time steps is applied to both implementations. They produce similar results for an electrical and electrochemical field problem. This work shows that mesh smoothing does not result in higher accuracy when modeling a moving anode front. Adjusting only the boundary elements is sufficient when frequent re-meshing is used.

本研究提出一個四階段的消費者重購承諾心理評價程序模式，認為消費者將依據知覺品質和期望品質的比較形成品質失驗，然後藉由內在的價值函數將品質失驗轉換成為同樣是失驗觀點的個別交易滿意度（滿意度失驗）。在形成個別交易滿意度之後，消費者將依循累積滿意度基礎的個別交易滿意度邊際微調模型來形成當期的累積滿意度，並且依據當期的累積滿意度和當期的忠誠門檻值比較的結果，進而產生品牌忠誠或品牌轉換的行為意圖。 整體而言，失驗觀點的個別交易滿意度（滿意度失驗）和品質失驗之間的關係大致服膺期望理論價值函數的特性。此外，本研究提出的累積滿意度基礎的個別交易滿意度邊際微調模型也獲得支持，並進一步確定累積滿意度的調整過程主要是採行性線的調整模式。最後，本研究提出的累積滿意度忠誠門檻模型亦獲得實證證據的充分支持。因此，一旦當期的累積滿意度決定之後，消費者將以他心目中對競爭品牌的累積滿意度做為比較的基礎、當作忠誠門檻值，進行焦點品牌累積滿意度和競爭品牌累積滿意度的比較，並且依據比較的結果形成品牌忠誠或品牌轉換的行為意圖。 / This study proposes a four-stage model about the process of consumers’ repurchase commitment. The model postulates that consumers would result in quality disconfirmation based on the result of comparison between perceived quality and expected quality, then transform it through intrinsic value function into transaction-specific satisfaction which is defined as satisfaction disconfirmation. Once transaction-specific satisfaction is formed, consumers would result in current cumulative satisfaction according to cumulative satisfaction-based transaction-specific satisfaction marginally adjusting model that depicts current cumulative satisfaction as a function of previous cumulative satisfaction and current transaction-specific satisfaction. And finally, according to loyal threshold model of cumulative satisfaction, intention to repurchase or switch buying would be formed based on the relative magnitude between cumulative satisfaction and loyal threshold which is defined as cumulative satisfaction towards a main competing brand. Overall speaking, the relation function between quality disconfirmation and transaction-specific satisfaction exhibits most traits of value function depicted in the prospect theory. Furthermore, the cumulative satisfaction-based transaction-specific satisfaction marginally adjusting model proposed by this study was supported by experimental data, and the result shows that the adjusting process of cumulative satisfaction complies mainly with linear adjusting model. And finally, the loyal threshold model of cumulative satisfaction was fully supported by experimental data, and the result implies that consumers would take the cumulative satisfaction towards a main competing brand as the comparing basis, i.e., loyal threshold, and then compare cumulative satisfaction towards a focal brand with this comparing basis to decide whether to repurchase the products of the focal brand or instead switching to buy the goods of the competing brand.

Sous l'effet de l'utilisation répétée de la notion de propriété des créances par le législateur et par les juridictions, l'urgence de l'élaboration d'une théorie de la propriété des créances apparaît. Or ce sujet suscite encore controverses, réserves, interrogations et incertitudes. L'alliance de la propriété et des créances apparaît souvent comme une hérésie. En effet, la notion de propriété des créances est généralement condamnée, non seulement parce que la propriété des biens corporels est considérée comme la seule propriété authentique, mais aussi parce qu'elle semble s'intégrer difficilement dans la distinction traditionnelle des droits réels et des droits personnels. Pourtant n'est-il pas logique de se poser la question de savoir si cet usage réitéré de l'expression « propriété des créances » ne constitue qu'un dérapage linguistique sans portée réelle, ou s'il s'agit de l'expression d'une réalité qui se serait manifestée par le vecteur du langage ? La condamnation doctr inale de la propriété des créances ne repose-t-elle pas sur des présupposés théoriques ? Le principal enjeu de cette thèse consiste à se prononcer sur la possibilité théorique de la notion de propriété des créances. Peut-on juridiquement employer le terme propriété, dans son sens technique, pour désigner la relation qui unit le créancier à sa créance, ou bien s'il faut s'en tenir à la notion de titularité ? Au vrai, cette question de l'existence du concept de propriété des créances est primordiale car elle est aussi préjudicielle à celle de la protection de la créance par le biais du droit de propriété. Une fois l'adaptation du droit de propriété aux créances réalisée, ces biens incorporels n'auront effectivement plus qu'à se glisser dans le moule de la propriété et qu'à se nourrir de l'intérêt fondamental de cette notion, le bénéfice de sa protection assurément très efficace. Au fil de ces travaux, l'on découvre néanmoins que seul l'assouplissement de la rigueur de la défin ition classique de la propriété concilié à l'affermissement de celle des créances rend possible la compatibilité des deux notions. / Under the effect of repeated use of the concept of ownership of receivables by the legislature and the courts, the urgency of developing a theory of property claims appears. This subject still arouses controversy, reservations, questions and uncertainties. The combination of property and debt is often seen as a heresy. Indeed, the notion of ownership of the claims is generally condemned, not only because the ownership of tangible property is considered the only real property, but also because it seems to fit easily into the traditional distinction between real rights and personal rights. Yet is it not logical to ask whether the repeated use of the phrase "property claims" only a linguistic slippage without real significance, or whether the expression a reality which would have emerged by the vector of language? The doctrinal condemnation of property claims is not she pa on theoretical assumptions? The main goal of this thesis is to decide on the theoretical possibility of the concept of property claims. Can we legally use the term ownership in its technical sense, to designate the relation between the creditor's claim, or whether to stick to the notion of authorship? In truth, this question of the existence of the concept of ownership of receivables is important because it is also referred to the protection of the debt through property rights. Once the adjustment of property rights claims made, these intangible assets will effectively more than slipping into the mold of the property and that feed on the fundamental interest of this notion, the benefit of its certainly very effective protection. Throughout this work, however, one discovers that only the relaxation of the rigor of the classical definition of property reconciled to the consolidation of claims that makes possible the compatibility of both concepts.

Within the educational psychology literature there is an abundance of research in the field of metacognition. The concentration of this research however has been in primary and secondary school contexts with little attention given to tertiary students' understanding or use of metacognition; there has been even less attention to whether age is a factor in tertiary students' perceptions of their metacognitive processes. The primary purpose of this study was to explore the perceptions of two distinct groups of first year university students, towards their understanding and usage of metacognitive processes and strategies. The two groups defined were traditional school leavers and mature age students. The findings from the exploration of these perceptions were compared to ascertain the similarities and differences in metacognitive processes between the two cohorts. The data collected for this study were obtained through a process of individual face-to-face in- depth interviews. The choice of this methodology was deliberate in order to gather rich data about the students' perceptions and experiences rather than attempt to measure their levels of metacognition against some predetermined standard. Data were collected and analyzed on the two constructs of metacognition which were identified in the literature search. These were metacognitive knowledge and metacognitive control. A range of affective variables such as self efficacy, motivation and expectancy of success, which impact on students' metacognitive abilities and processes, were also considered in the data collection and analysis. The findings indicated that age was a factor in determining some differences and similarities in students' perceptions of their own and others metacognitive processes. In certain cases the traditional school leavers' recency of experience with formal study was deemed an advantage; in others the life experience of the mature age students was perceived an advantage. In some instances the age of the student had no discernable impact on their understanding of, and ability to, utilize metacognitive strategies. These findings assist to broaden the understanding of student perceptions of metacognition in the tertiary context. The findings also make it imperative that tertiary institutions make fewer assumptions about the skills and abilities of their commencing students based on the criterion of age and offer more opportunities to assist students to understand the value of developing and improving their metacognitive processes.

Claims are special kind of property. They are tangible property, where its owner has limited possibilities of its exploitation. They ae property, which is bailed to another person without compensation. Claims are interest-free commercial credit granted to a debtor. High share of claims in total circulating property can affect negatively on trend of conditions for economic activity. Claims tie sources necessary to acquisition stock needful for production or business activity. In case of irrecoverable claims is possible to reach indirect reduction their evaluation in accounting by way of adjusting items. Claims are the only property, where is creation of adjustment on fulfilment of a condition tax deductible cost. On the limiation of claim do not arise obligation for creditor to eliminate claim from the property. Creditor can willingly decide of elimination of claim anytime. On fulfilment of conditions fixed in the Income Tax Act is junk value of claim tax deductible. When the lawful conditions are not fulfiled, in the case of claim retirement is not the cost incurred by the write-off tax deductible. Here is also the possibility to transfer a debt to another person. In this way is danger of default of payment eliminated. Achievement of claim settlement is also possible by inclusion mutual claims between creditor and debtor.
