Model of parallel planning of logistic and distribution processes
Babić, Darko; Ćavar, Ivana; Průša, Petr
The logistic activities represent an optimized response to the globalization processes, and the companies involved in such activities, with optimal planning of the logistic and distribution processes, realize higher profit and more stable position on the world market. Therefore, it is necessary to define the logistic and distribution processes, their elements and interrelations, effects, as well as planning process methods, and all this in order to optimize the operation of logistic operators.
Logistic-distribution processes are very complex, i.e. they consist of a multitude of details that occur in reality, but cannot influence the planning. Precisely therefore it is necessary to solve the real problems by simplified copies of these problems, the so-called models, as the basis for making a plan. The presentation of the real problem, the simplest possible but with all the necessary details and not ignoring several serious real factors, is called modelling (“art of model creation”).
The basic aim of planning the logistic and distribution processes is to achieve the uniformity and consistency i.e. continuity of the goods flows and the best possible usage of the traffic infrastructure and the transport means. Precisely this is of vital importance for the rational realization of the logistic functions, since good exploitation per time and capacity is the basic precondition for reducing the fixed costs which are, as is well known, extremely high in transport.
Based on this it is obvious that planning of logistic and distribution processes has to be performed at the level of the entire system, and that it is necessary also to carry out separate planning of elements of the logistic and distribution systems, taking into consideration their interwoven condition, with the aim of creating optimal logistic processes.

Sources of Funds for the Development of Air Transport Infrastructure in Poland in the EU’s new Financial Perspective 2007-2013
The paper shows the possibilities of financing the development of the air transport infrastructure within the new financial perspectives 2007-2013 of the EU. Investment needs in the air transport sector were shown in the context of market development in Poland. European funds on investments in the air transport sector and related with access to the airports were discussed. Possibilities of using EU funds in private-public partnership were shown, especially on the basis of so called hybrid model of financing an investment in airport and airport-related infrastructure, which consists on simultaneous use of EU funds, private capital and domestic public means.

New methods proposal for VoIP transmission
Bachratá, Katarína; Boroň, Juraj; Rosival, Boris
For speech transmission is important to make conversion of analog speech signal to digital form. Signal conversion in classic and IP telephony uses Shannon basis decomposition. The Shannon basis used to be the best for speech signal conversion. The reason was, that the computing of the coeficients is very simple, because they are equal to samples of the original signal. In this paper are included teoretical results for new possibilities of transmission voice over IP using different basis. Their advantages rests in better reconstruction of the original signal also in case if we loose some of the data during the transmission(or they aren’t delivered on time and waiting for them will cause degradation of received signal). The dependance between quality of reconstructed signal and percentage of lost packets is estimated by signal to noise ratio SNR. In this paper are described results of simulation for SNR estimation in case of specific choice of generating basis function.

Extending annotational SSML into structural content for speech synthesizer
Klimo, Martin; Mihálik, Igor
This paper describes a way of extending standard SSML language that is primary used for annotating input text into fully structural content used internally for speech synthesis. It explains approach used for processing such SSML input using rule based engines technology and implicit invocation. For reasoning in implicit invocation a formal language had to be created. This formalism is also shortly described in this paper.
