Opis:
Vladimír Šlajch’s organ at Svatá Hora in Příbram draws to a close an important stage of his life. Having had equal success building other organs, the most important and largest of which is in the German town Bruchsal, this instrument represents a unique achievement. These days we usually encounter organs that conform to the wishes of organists and organ experts that every new instrument be built primarily with the convenience of the performer in mind. The organ at the Basilica of Our Lady of Svatá Hora is different. Instead, it embodies a synthesis of original solutions and tried-and-true traditions. Vladimír Šlajch built it as a sort of tribute to the organ builders who once worked in Bohemia. The decorating of the prospect pipes makes reference to Abraham Starck from Loket, Ondřej Kokštejn from Příbram, and the organ builder Bedřich Semrád from the Central Povltaví Region. The tracker action for the manuals and registration is mechanical. Because of this tracker action constructed strictly in accordance with Baroque models, the organ makes an audible clicking sound when played, and in addition, because of differing distances for individual connections, the clicking is not equally loud for each note. The clicking bothers many organists, but the organ builder insists that the design is justified, using centuries of organ building tradition as his argument. In my opinion, playing the great Svatá Hora organ successfully depends upon approaching it with a great deal of humility and upon the ability to adapt oneself to the instrument, along with having a deep understanding of the features specific to the organ. It is true that the level of disruptive clacking noise reveals the organist’s particular style of playing, but it is also true that the attempt to make less noise forces each of us not only to depress, but also to release the keys as carefully as possible, and with this kind of tracker action, moving one’s fingers in this way naturally also influences the sound of legato passages and the smoothness of the phrasing. While the attempt to play without making noise is entirely futile, especially when using quieter registration, it has an absolutely fundamental influence over the quality of the melodic lines within the context of the polyphony, and that influence is clearly for the better. From the layout of the instrument, we clearly see the wealth of sonic possibilities at our disposal. The many colours of the registers can be combined into an almost inexhaustible quantity of shadings. While the organ is intended for playing older music, mainly of the Renaissance, Baroque, and Classical eras, neither Romantic nor contemporary compositions are out of the question. One must simply consider which ones to choose and which ones would be less appropriate, because although the tuning is set at a' = 440 Hz at 18 degrees Celsius, the temperament is slightly unequal, reminiscent of Valotti tuning. The spatial layout of the individual divisions of the Svatá Hora is quite unusual, but it still respects longstanding tradition. The manuals have a chromatic range from C to f'''. The Great division (manual II) takes up the two most spacious parts of the organ case. It is divided into a C and C sharp side. A smaller division called the Positiv, placed in front above the organist’s head, is connected to a third manual. The first manual plays the Unterwerk or Choir division, which is divided into bass and discant. Each register of the Unterwerk is activated separately for the bass and discant on the left and right sides of the console. The organ builder placed the Unterwerk right behind the console in the pedestal of the organ. Like the Great division, the Pedal is divided into a C and C sharp side, and each takes one of the adjacent loft areas on the sides. On the other hand, a three-rank pedal Cornet plays from the Crown Positiv or Kronwerk located at the top just under the vault. Representing a peculiar feature are the two sets of chimes (Zimbelstern), which are located on the pedal cases on opposite sides. A noteworthy property of the organ at Svatá Hora is its sonic versatility, perhaps even universality to a certain extent. If you listen to it, you soon get the impression that you are hearing a Czech or south-German Baroque sound, then it suddenly seems that you have found yourself listening to a Silberman organ in nearby Saxony, until finally you notice a passage that seems to come from the Baltic, with sounds of the ideal organ of Bach’s forerunners of the north-German school. Then the combination of the Principal on the Great manual and the Bifara stop tuned to create vibrato makes us wonder, might we perhaps be in Italy? And at the same time, although the organ is in a Catholic church, the instrument seems to the organist to be in perfect accord with the music of Johann Sebastian Bach. The acoustics and reverberation here are exceedingly suited to the spirit of Bach’s Protestantism. The Svatá Hora organ is indispensable for the successful interpretation of Bach’s music within the context of this region. Notwithstanding all of their beauty, the Baroque organs of Bohemia have a small range of tones, with a lack of the needed keys, pedals, and registers, while the later organs are oriented towards the Romantic musical style, and even newer organs usually suffer from insufficient artistic quality caused mainly by mass production methods. By contrast, the new Svatá Hora organ is of great artistic worth; it even fits the basilica perfectly from a visual perspective. Once the organ was finished, we could hardly imagine that not long beforehand the instrument had not yet been installed. These days, an organ is very rarely so perfectly matched to the place for which it is intended.

Opis:
Design work related to the implementation of new aerospace elements requires the use of 3D-CAD modelling techniques and rapid prototyping, which makes it possible to significantly accelerate the deployment of new solutions. The article presents the possibility of using some methods of rapid prototyping to produce the research model of a wheel hub forming part of the landing gear. Incremental rapid prototyping methods - JS (Jetting System), SLA (Stereolithography), FDM (Fused Depositing Modelling) - have been characterized with regard to the technology of executing a hub model, the parameters of the manufacturing apparatus, and comparing basic technical data of materials used in the analyzed processes. One of the elements of the process of prototyping was to process data in other equipment for rapid prototyping. This process consisted of the following steps: defining the parameters of model building, determining the appropriate model settings in the workspace of manufacturing equipment, editing the supporting structure, verifying the subsequent layers through the simulation of model building process, generating output numerical procedures for manufacturing equipment. Manufactured prototypes have been evaluated of dimensional accuracy with the use coordinate measuring machine. Also measured the surface roughness. Conducted studies were the basis to determine the applicability of various methods of rapid prototyping in the process of research and manufacturing aircraft wheel hub.

Opis:
This paper presents numerical analysis of efficiency of different shapes and material composition of piezoelectric actuators used for vibration reduction. Four numerical models representing a plate clamped on all sides with two attached piezoelectric elements were created. For each model, one element had the same shape and composition and was used for plate excitation, and the other one, used for vibration reduction, had different shape and possibly material composition and could be of square or circular shape with either homogeneous or two-part material composition. Two modes were taken into account: the first mode and the fifth mode. Analysis of results was performed with ANSYS software.

Opis:
In the article, I present the findings of scientific insight into issues that I call tablet children. I provide alarming data on the number of children aged 6 months and a little bit older who are given access to tablets and smartphones by adults. I quote the most important findings included in the theory of representation by Jerome S. Bruner to explain the following: – What makes babies and toddlers use tablets and smartphones in a remarkably efficient way; – Adverse differences in representations created by children based on experiences gathered in the world of real objects and in the virtual world; – Distortions in the outlines of mental representations formed by young children when they watch images on tablet and smartphone screens too frequently. Being given access to these devices is particularly dangerous for young children, who have not yet created the outlines of the representations of three-dimensional objects and three-dimensional qualities of space in their minds. Distortions in the outlines of representations are difficult to fix as subsequent experiences only complement and expand the existing representations. Since the existing representations take part in creating new representations, the new ones are not fully correct either. I also argue the need for serious research that should aim to determine the far-reaching results of tablets and smartphones being available to babies and young children. This will help to come to terms with these devices educationally and also to determine when and for how long they can be made available to children so that they are safe for children's mental development.

Opis:
Irrespective of the dielectric constant (ε) or the hydrogen-bonding ability of a pure solvent, the lowest excited singlet state (DBA*) of 9,10-dibromoanth racene (DBA) is quenched by ground-state 2,5-dimethylhexa-2,4-diene (DMHD) giving rise to the appearance of an exciplex emission. By means of sub-picosecond and nanosecond laser photolysis as well as steady-state photolysis, however, the following solvent-dependent results are obtained; (1) in acetonitrile (ε=37.5) and acetone (ε=20.7), an exciplex (DBA-DMHD)* formed between DBA* and DMHD generates the DBA radical anion (DBA$\text{}^{•-+}$) as an intermediate for formation of 9-bromoanthracene (BA) from DBA; (2) in ethanol (ε=24.6), 2-propanol (ε=19.9), 1-octanol (ε=10.3), diethyl ether (ε=4.34), and heptane (ε=1.92), a neutral radical species (NR$\text{}^{•}$) generated by decomposition of (DBA-DMHD)* (or by a reaction of DBA* with DMHD) is an intermediate for formation of a dibenzobicyclo[2.2.2]octadiene-type compound (a [4+2] adduct); (3) both DBA$\text{}^{•-}$ and NR$\text{}^{•}$ are generated in methanol (ε=32.7) but the rate (v) of BA formation upon steady-state photolysis of DBA in the presence of 1 M DMHD decreases in the order of v(acetonitrile, ε=37.5) > v(acetone, ε=20.7) > v(methanol, ε=32.7). It thus can be concluded that the mechanism of exciplex decomposition and the reaction of DBA* with DMHD are affected by not only the dielectric constant of a pure solvent but also its hydrogen-bonding ability.

Opis:
After a brief review on surface phonons, we focus on resonant phonons in adsorbed thin layers. Such resonances may in general be understood within the substrate bulk band as thin layer modes shiften and broaden by the interaction with the substrate phonons. These resonant phonons appear as well-defined peaks in the phonon density of states. Their experimental study started recently by Helium atom scattering spectroscopy. This review will end by a prospective revue done mostly after the presentation of two unpublished results. First the slab resonant phonons may almost be confined in the surface slab even for frequencies falling within the bulk phonon band, if the surface slab is separated from the substrate by a buffer layer. The other prospective unpublished result deals with a model system in which the propagating phonons reach a space point from which they can continue to propagate through two different finite in space channels before reaching again a homogeneous uniform path. Such a system exhibits some frequencies for which the transmission factor vanishes. This phenomenon is related to the resonances associated with the finite additional path offered to the propagation of the phonons.

Opis:
Technika WebRTC, bazująca na językach HTML5 i JavaScript, umożliwia natywną transmisję informacji multimedialnej w czasie rzeczywistym pomiędzy przeglądarkami WWW. Chociaż same strumienie mediów, a także transmisje niemedialne (obecne w architekturze WebRTC, choć nie wymagające czasu rzeczywistego), przesyłane są bezpośrednio pomiędzy przeglądarkami, do przesyłania informacji niezbędnych do zarządzania sesją (a konkretniej: nawiązywania sesji) potrzebny jest serwer sygnalizacyjny. Serwer taki może być traktowany jako punkt spotkań dwóch lub więcej systemów końcowych wykorzystujących technikę WebRTC. W artykule przedstawiono zasady budowy takiego serwera za pomocą aplikacji tworzonych w języku JavaScript i uruchamianych w środowisku node.js. Omówiono środowisko node.js oraz pokazano przykład prostego serwera sygnalizacyjnego, budowanego na potrzeby wymiany komunikatów i (lub) inicjowania (wideo)telefonii lub (wideo)konferencji z małą liczbą terminali. Serwer ten łączy uczestników tylko w ramach pojedynczej sesji 1-do-1 lub wielu-do-wielu. Pomimo dużej prostoty, przykładowy serwer jest w pełni funkcjonalnym serwerem sygnalizacyjnym WebRTC, umożliwiającym realizację, między innymi, (wideo)telefonii pomiędzy przeglądarkami używającymi WebRTC.
Web Real-Time Communications (WebRTC) technology is an enabler of native transmission of multimedia information between two and more Web browsers. WebRTC is based on HTML version 5 (HTML5) and JavaScript languages. Although both real-time media streams (audio, video) and non-real-time non-media flows (also present in WebRTC architecture) are transmitted directly between browsers, to enable transmission of information necessary for session management (and more precisely: session establishment) purposes, a signalling server is needed. Such server may be regarded as a rendez-vous point of end systems that use WebRTC technology. In this paper, node.js run-time environment and principle of building of Webrtc signalling server with the use of scripts written in JavaScript and run in node.js are presented. Example of script of a simple signalling server also is shown. The exemplary server connects users of one and only session, although this session may serve not only one-to-one, but also many-to-many connections. Despite its simplicity, this is a fully functional signalling server, able to serve signalling messages for purposes of message exchange, or for purposes of initialization of WebRTC-based Internet telephony or simple conferencing systems.

Opis:
The shedding process and acoustic flow formation in the region of outlet of a cylinder duct has been investigated by means of the particle image velocimetry (PIV) technique. The research work on the behavior of the sound field at outlets of waveguides addresses issues of importance to industrial applications. The obtained results can be used in a number of industrial applications involving pipes, ducts and tubing. In our investigation the acoustics flow fields are measured with a phase-locked PIV system with high sampling rate and large internal memory block using DAVIS v. 8.11 software. A cross-correlation method, in conjunction with the FFT analysis, is used as a vector processing algorithm. A series of PIV vector maps was used to evaluate the acoustic velocity field at the open end of circular tube throughout the acoustic cycle for frequencies of 700 Hz and 1400 Hz. Six phase steps were assumed for one frequency cycle and the characteristic signal was extracted from the velocity data step and shown graphically.
