Opis:
Together with the development of information and communication possibilities of the Internet there is an increase of the role of the customer as the partner in the process of co-creating innovation with the utilization of widely understood model of open innovations. The aim of the article is the assessment of the efficiency of communiaction channels used by firms in relations with the customer. In the assessment there were used findings of research carried out among students who declared activities in scope of: notifyings innovative ideas, testing of products (services) or undertaking the role of a consultant. The assessment took into account the criteria of comfort, speed and efficiency from the perspective of customer and the reaction of a company in the given channel of communication. E-mail, sms, forum, blog, community portal are comfortable but their utilization by companies requires improvement in respect of rate of reaction and efficiency. The channels of communication in the synchronous mode were highly evaluated in respect of efficiency and comfort: telephone, chat, video conversation and Skype. The best but still little widespread solutions are platforms for ideas reporting and the collaboration with the user which are created within company's portals.

Opis:
As far as the rapid development of global marketing network is concerned , it is easy to notice that logistics is becoming increasingly important. The growing competition makes these networks more efficient. More and more opportunities to bring products to the customer disorganize sales network management. The analysis of the effectiveness of distribution channels allows a close examination of efficiency of how the company reaches its customers. It also supports decisions regarding the introduction of new, previously unused channels of distribution, or modification of the already in-use ones. The range of work included a manufacturer specializing in meat processing and production of meat products, distributed in southern Poland. Using the point-analytical method, the effectiveness of distribution channels used in the company was evaluated. As a result, it was possible to determine the performance of individual sales channels. There were three distribution channels: by-company, sponsored and networking. The most effective appeared to be the networking channel, which scored a total of 235 points. Given the greatest potential of distribution, this channel, in terms of the size of the batch supplied to markets, without doubt will continue to be one of the leading directions of development in the future of the company. In second place was the by-company channel with 195 points, while the sponsored channel was the least effective. However, as a conclusion from the information gathered from the company itself, each channel will be developed in the future, proportionally to their current rank.

Opis:
This paper presents the results of an experimental study and mathematical modeling of the effect of dynamic instabilities on the condensation phase transformation of the refrigerants homogeneous R134a and its replacement in the form of isomers R1234yf and R1234ze and R404A or R507 and R448A in pipe mini-channels. In the case of homogeneous chlorofluorocarbons (CFCs), it is the 1234 isomers that are envisioned as substitutes for the withdrawn ones with high ozone depletion potential and global warming potential. For zeotropic and azeotropic mixtures, for example, these are R507 or R448A. The paper presents a dimensional analysis procedure based on the Buckingham Π theorem to develop a regression velocity model of pressure dynamic instabilities. The experimental part of the work was carried out with the use of tubular mini-channels with internal diameter 1.40–3.3 mm.

Opis:
The statistics of the error process generated by a discrete super channel formed by the concatenation of a constrained encoder, a non-renewal finite state channel (FSC), and a constrained decoder is studied in this paper. First, recursions are developed for the error weight distribution. This statistics is relevant to the design of coding schemes and interleaving in concatenated. systems. We also study the renewal nature of the residual error process as modified by the constrained decoder. Ferreira et al. conjectured that if the channel model is a renewal FSC, the super channel can be modeled as a similar renewal model. We use a statistics called the multigap distribution to analytically disprove this hypothesis. Furthermore, the effect of interleaving is investigated from a new perspective using the variance of the multigap distribution.

Opis:
The paper describes some turbulence measurements carried out in an experimental compound channel with flood plains. The surface of the main channel bed was smooth and made of concrete, whereas the floodplains and sloping banks were covered by cement mortar composed with terrazzo. Instantaneous velocities were measured be means of a three-component acoustic Doppler velocity meter (ADV) manufactured by Sontek Inc. This article presents the results of measurements of primary velocity, the distribution of turbulent intensities, Reynolds stresses, autocorrelation functions, turbulent scales, as well as the energy spectra.

Opis:
Although the sedimentation and diagenesis of the Polish Zechstein Limestone strata (Ca1, Permian) already have been investigated, relatively little has been done to resolve their petrophysical potential. Therefore, the gap between sedimentological and petrophysical studies was bridged through an integrated analysis of geological and geophysical data. The results of core description, polarized-light microscopy, well log interpretations and laboratory measurements on core samples were combined with previously published nuclear magnetic resonance (NMR) and X-ray microtomography (μCT) data, especially helpful in the recognition of pore geometry. The Ca1 strata of the Brońsko-1 and Brońsko-2 wells, located on the Zechstein Brońsko Reef (West Poland), were studied to determine the influence of fossils on porosity and permeability. It was concluded that greater diversification of the original biota led to an increase in porosity and variation in pore geometry. While encrusting organisms such as foraminifers promoted the development of channel and fracture porosity, the dissolution of the primarily aragonitic bivalve and gastropod shells and the shells of terebratulid brachiopods often gave rise to the formation of cavernous and mouldic porosity. The channels appear to be most common in the bryozoan-foraminifer biofacies, representing a shallowing of the depositional environment. Caverns, in turn, corresponded to the organisms of the brachiopod-bryozoan and the lightly karstified bivalve-gastropod biofacies, both of which probably experienced the influence of sabkha conditions, leading to a general decrease in porosity. The bryozoan zoecia tended to enhance both primary intraparticle voids, and after their dissolution, secondary intraparticle pores, which showed limited connectivity in the high-energy Acanthocladia biofacies, where considerable fragmentation of fossils took place, hence decreasing the permeability. Anhydrite cementation was found to be the most pronounced factor controlling porosity destruction, while dolomitization enhanced it significantly, especially for the stromatolitic biofacies, where small, unconnected vugs were formed owing to this process. The permeability is typically below 100 mD, and this is caused by the rich diagenetic history of the reef, that recorded marine, sabkha-related and burial cementation, now represented by the different fabrics of anhydrite, calcite, and dolomite.

Opis:
This paper describes the use of computational methods for solving the flow of the air-cooling in the large synchronous machines where it is used to cool the stator winding and stator radial channels which are located between the stator packet sheets. The overall process flow is mostly influenced by the size of air gap between stator and rotor, the shape of the radial channels, and by flow rates in machines. This paper mostly discusses about the influence flow rate of the cooling medium which has effects on the pressure distribution and flow rate in the radial channels. Cooling medium considered in this article an air and for and for calculation was chosen ANSYS CFX.

Opis:
Signal-to-noise ratio (SNR) information is required in many communication receivers and their proper operation is, to a large extent, related to the SNR estimation techniques they employ. Most of the available SNR estimators are based on approaches that either require large observation length or suffer from high computation complexity. In this paper, we propose a low complexity, yet accurate SNR estimation technique that is sufficient to yield meaningful estimation for short data records. It is shown that our estimator is fairly close to the (CRLB) for high SNR values. Numerical results also confirm that, in terms of convergence speed, the proposed technique outperforms the popular moment based method, M2M4.

Opis:
There are many diseases related to ion channels. Mutations in muscle voltage-gated sodium, potassium, calcium and chloride channels, and acetylcholine-gated channel may lead to such physiological disorders as hyper- and hypokalemic periodic paralysis, myotonias, long QT syndrome, Brugada syndrome, malignant hyperthermia and myasthenia. Neuronal disorders, e.g., epilepsy, episodic ataxia, familial hemiplegic migraine, Lambert-Eaton myasthenic syndrome, Alzheimer's disease, Parkinson's disease, schizophrenia, hyperekplexia may result from dysfunction of voltage-gated sodium, potassium and calcium channels, or acetylcholine- and glycine-gated channels. Some kidney disorders, e.g., Bartter's syndrome, policystic kidney disease and Dent's disease, secretion disorders, e.g., hyperinsulinemic hypoglycemia of infancy and cystic fibrosis, vision disorders, e.g., congenital stationary night blindness and total colour-blindness may also be linked to mutations in ion channels.

A variety of communication channels, which can use the organisation meant that the process is more difficult and requires huge effort, work, and learn in a very short time. The domain of specialists, PR is dialogue with the environment, is already known to many of the tools of PR, but it's just the Internet promotes the improvement of this interactive communication. Every action that we take on the Internet has a dimension of all forms must be present but PR surrounded with special care. Internet deep into relationships between an organization and its environment. Society is not able to permanently trust organization or institutions, which make sense, the aims and principles of ac-tion does not understand. PR communication methods with the environment, these classic with modern, permeate each other. This article attempts to clarify what is communication with the environment and what changes occur in the communication process as a result of digitisation in the practice of the use of PR tools.
