In this article, we develop a programmatic notion of innovation ecosystems, which emphasizes the analysis of different forms of distributed innovation without reducing the perspective to the role of a focal organization. It highlights relationships between communities and corporate firms as nexus for distributed innovation and elaborates how different facets of openness shape the dynamic of the ecosystem. Thus, our model allows for the analysis and comparison of a broad scope of constellations, their particular coordinating mechanisms as well as related advantages and disadvantages. We apply this framework to two specific cases of distributed innovation, the RepRap 3D printer and the ARA modular smartphone, in order to delineate how differences in the forms of openness affect the prevalent relationships between communities and firms as well as the constituting functions of their particular innovation ecosystem.

The article presents a theoretical analysis of existing concepts to evaluate the non-failure of RC structures in operation. To perform the analysis, the authors considered a number of scientific works of both Ukrainian and foreign researchers. The main focus was on works in which the model of the stochastic nature of the RC structure operation included random parameters of acting loads, as well as the reserve of its bearing capacity and serviceability (geometric dimensions of cross sections of constructive members, strength and deformation characteristics of materials, etc.). Among others, according to the authors, important problems in terms of analysis of a single work were the volume of statistical selection of random parameters, their number and impact on the study result, as well as rationality of the adopted method of calculating the probability of failure (or non-failure work) of RC structure in operation. Based on the processing of a number of scientific works, the authors highlight the relevance, advantages and disadvantages of the concepts of non-failure assessment proposed there, as well as the formulate the conclusions and recommendations for further experimental and theoretical research in this area.

AbstractTest results are presented for an additive material prepared of acrylonitrile-butadiene-styrene on a 3D printer. Dynamic tension experiments have been carried out using a tower-type drop hammer with an accelerator. Data obtained from different specimens demonstrate that high-strain-rate tensile experiments are feasible if the working part of the specimen is decreased. A theoretical analysis of test data using the incubation time criterion has been performed, and it has been found that analytical results are in good agreement with experimental data.

Accuracy Of Measurements

In recent years, in the oil production industry there is a tendency of mass use of stationary multiphase metering units for determining oil, water, and associated gas flow rates in the recoverable well production. Automated group metering units, allowing to cover the whole group of wells in rotation metering mode, became widespread. The necessity of equipping wells with individual or group measuring devices is dictated, first of all, by the economic tasks of improving oil recovery factor and production optimization. In these conditions, the task of periodic verification of stationary measuring devices in the field with the help of mobile standards-measuring devices of higher accuracy class becomes urgent. The standard’s mobility and the need to work in the field with fluids of different composition significantly complicates the task of creating such a device. The practicality and economy of the created units first of all depends on a choice of a measuring method determining the design of the unit. This article analyzes the existing types of equipment for measuring oil, gas, and water consumption at the oil production wells. Showing the main advantages and disadvantages of each of them, this paper proves the necessity of using complex solutions based on different physical principles to improve the accuracy of measurements. The authors have proposed a combined scheme of a mobile standard of the 2nd category with a dynamic method for measuring the phase rates at the core. The unit performs a multi-stage partial separation of the input multiphase flow into liquid and gas phases and determines the fractions of water and oil in the liquid stream using a hydrostatic-type mixture composition analyzer. In addition, this article indicates the ways of increasing the accuracy of the measuring installation.

The aim of this study was to briefly provide the history of the term ‘political correctness’ and discussed some of its views as well as mentioning two studies to support the claims. The importance is to identify the advantages and disadvantages of political correctness and to what extent the controversies over it could serve the political parties. The advantage of political correctness is to prevent individuals from harm, offensiveness, and discrimination, whereas the disadvantage is the ideological and political intervention because it would be difficult to separate cultural/political ideologies from a language.
