UMTS radio access network optimization in Opnet Modeler environment
Toman, Petr ; Herman, Ivo (referee) ; Novotný, Vít (advisor)
The differences between networks of mobile operators can be in their achitecture or the optimization of each network. The architecture is standardized which means there will only be differences in the willingness of mobile operators to invest in newer network elements. Network optimization is more important. The way of optimization isn't strictly given and depends on how the operator deals with it. The most important attribute in optimization is balance. The operators try to achieve balance among three important parameters. Those are capacity, coverage and maintaining QoS. Optimization depends on RRM algorithms. The algorithms include various functions such as admission control, congestion control, handover control, power control, etc. These elements don’t only affect the optimization but also affect each other, because they cooperate with each other. For example, an incorrect admission control of the network leads either to frequent network congestion because of a large number of participants in the network (participants are dissatisfied with the services offered by the operator) or to low utilization of the network because of too few participants in the network (the operator is dissatisfied because he is losing the possible earnings). Neither of these posibilities is good for the mobile operator, therefore it is important that the admission control is well balanced.
Analysis of local reverse charge on VAT and guarantee of the customer as the tools the Czech Republic introduced in its fight against tax frauds
Roďanová, Kateřina ; Toman, Petr (advisor) ; Vítková, Jana (referee)
This dissertation analyses local reverse charge on VAT and guarantee of the customer as the tools the Czech Republic introduced in its fight against tax frauds and shows obstacles which could arose during its transition into the Czech tax system.
Chain transactions - VAT analysis and optimization options
Doubková, Anna ; Toman, Petr (advisor) ; Bauernöplová, Veronika (referee)
This diploma thesis is focused on the issue of chain transactions. The main aim of the thesis is to suggest the companies participating in the model chain transactions in the case study the appropriate measures leading to the optimization of tax obligations related to VAT. The measures are divided according to three criteria: tax period harmonization, tax savings in cash flow and elimination of administrative burden. The key provisions in the recast of the Sixth Directive, the VAT Act and the case law of the Court of Justice of the European Union are analyzed. Based on the comparison of various solutions, the most optimal procedures are assessed and the appropriate measures are recommended.
Place of supply for services and its recent changes in relation to the implementation of new European Union Directives
Rechtik, Václav ; Toman, Petr (advisor) ; Bauernöplová, Veronika (referee)
This paper is dedicated to problematics of determining the place of supply, which was significantly changed at the beginning of 2010. These changes were linked with the implementation process of the European Union Directives 2006/112 and 2008/8. The general rule was changed and the list of exception, which belongs to special rule, was shortened. In this paper I am analyzing these changes and present model examples, where I describe these changes.
Application of affinity capillary electrophoresis for quantitative characterization of hexaarylbenzene-based receptor binding with alkali metal ions in methanol
Ehala, Sille ; Makrlík, E. ; Toman, Petr ; Kašička, Václav
Affinity capillary electrophoresis was found to be suitable and effective tool for the quantitative evaluation of strong as well as weak interactions between hexaarylbenzene-based receptor and several alkali metal ions in methanol. The selectivity of the above receptor expressed by binding constants towards alkali metal ions was found to increase in the order of Na+ < Li+ < K+ < Cs+ < Rb+.
Molekulární proudový spínač: základy a charakterizace modelového systému
Weiter, M. ; Vala, M. ; Nešpůrek, Stanislav ; Toman, Petr
The kinetics of the reversible photochromic reaction merocyanine - spiropyran, which manifested the annihilation of the dipolar species, was studied using the optical and impedance methods.
Quantum mechanical calculations of the properties of oligosilanes
Toman, Petr
Quantum mechanical study of polarons in oligo[methyl(phenyl)silanes] (OMPSi) was performed. The conformations of the defect-free OMPSi and OMPSi containing positive and negative polaron were optimized by measns of B3LYP method. For comparison and evaluation of the substituent effects, the conformation of the unsubstituted oligosilane was also calculated. The conformations were described by means of Si-Si bond lengths and Si-Si-Si bond angles. The negative polaron conformation shows a significant chain stretching. On the other hand, the positive polaron conformation is shrunk. The explanation is based on the changes of the electron densities. There is also a strong influence of the substituents on the conformation of the negative polaron. The middle Si-Si bond is much shorter for the substitute oligomer and the bond angles are smaller. On the other hand, the influence of the substituents on the conformation of the positive polaron is small.
