Abstract
Für viele Anwendungen sind die Oberflächenqualität und die geometrische Genauigkeit von Teilen, die mittels Laser-Strahlschmelzen (LBM) hergestellt werden, nicht ausreichend. Um die Prozesszeiten der notwendigen spanenden Nachbearbeitung zu reduzieren, kann eine Hochgeschwindigkeitszerspanung realisiert werden. Durch eine optimale Abstimmung der additiv-subtraktiven Prozesskette soll das Potenzial der additiven Fertigung voll ausgenutzt werden.

Predicting and Manipulating Cone Responses to Naturalistic Inputs
Authors: Angueyra Juan M. , Baudin Jacob , Schwartz Gregory W. , Rieke Fred 
Published: December 2021

Primates explore their visual environment by making frequent saccades, discrete and ballistic eye movements that direct the fovea to specific regions of interest. Saccades produce large and rapid changes in input. The magnitude of these changes and the limited signaling range of visual neurons mean that effective encoding requires rapid adaptation. Here, we explore how macaque cone photoreceptors maintain sensitivity under these conditions. Adaptation makes cone responses to naturalistic stimuli highly nonlinear and dependent on stimulus history. Such responses cannot be explained by linear or linear-nonlinear models but are well explained by a biophysical model of phototransduction based on well-established biochemical interactions. The resulting model can predict cone responses to a broad range of stimuli and enables the design of stimuli that elicit specific (e.g., linear) cone photocurrents. These advances will provide a foundation for investigating the contributions of cone phototransduction and post-transduction processing to visual function.SIGNIFICANCE STATEMENTWe know a great deal about adaptational mechanisms that adjust sensitivity to slow changes in visual inputs such as the rising or setting sun. We know much less about the rapid adaptational mechanisms that are essential for maintaining sensitivity as gaze shifts around a single visual scene. We characterize how phototransduction in cone photoreceptors adapts to rapid changes in input similar to those encountered during natural vision. We incorporate these measurements into a quantitative model that can predict cone responses across a broad range of stimuli. This model not only shows how cone phototransduction aids the encoding of natural inputs but also provides a tool to identify the role of the cone responses in shaping those of downstream visual neurons.

Published: December 2021

A numerical simulation of the intake and compression stroke and fuel spray and combustion in a direct injection compression ignition engine was performed using the Converge CFD software. For this purpose, the Reynolds Average Navier-Stokes (RANS) k-e RNG model and an n-dodecane kinetic mechanism were used in order to obtain the flow fields in the cylinder and to perform the breakup time analysis of the Kelvin-Helmholtz model in the variables related to the spray and combustion. The turbulent flow inside the cylinder was analysed, obtaining consistent results with experimental pressure data and other research authors. The droplet breakup time is evaluated as a function of the breakup time constant (B1), the initial droplet radius (ro), the wavelength and the maximum growth rate ( . The results indicate that the numerical method and the models used in this work are adequate to perform subsequent representative combustion analyses with values of B1=7. It was possible to show that the formation of the species OH is greater for low values of B1. Also, higher values of the breakup time, variables such as temperature, pressure, fuel evaporation, ignition delay, and species formation are affected.
The role of self-regulation and perceived self-efficacy in adaptation to home-office work during the pandemic
Authors: Kovács Zsuzsa , Kálmán Csaba 
Published: December 2021

Abstract
As a consequence of the unprecedented labor market circumstances that the prolonged Covid-19 pandemic brought about, organizations have faced challenges never seen before. One such challenge was the sudden ubiquity of working from home, which resulted in an intensive learning experience for employees and employers alike. While there is an increasing body of research on working from home in general, the perceived effectiveness of this mode of working is still under-researched. This niche provided the inspiration for us to investigate what factors might influence employees' self-efficacy in working from home arrangements. We conducted a mixed-methods case study by collecting both qualitative and quantitative data from 24 employees of a division of the Hungarian subsidiary of a chemical and consumer goods multinational. The purpose of our investigation was to gain a deeper understanding of perceived self-efficacy and self-regulation during the learning processes that the participants experienced under the new circumstances. Results suggest that the perceived high level of work-efficiency among the employees of the examined division was based on the firmly controlled work-division, trusting managers, as well as supportive and clear communication, which created space for autonomy in the adaptation process. The findings also revealed that self-reflection acted as a predictor of perceived work self-efficacy.

Published: December 2021

This paper describes the process of shooting a mobile armored combat vehicle with directed fragmentation-beam shells as a discrete-continuous random process. Based on this approach, a stochastic model has been proposed in the form of a system of Kolmogorov-Chapman differential equations.
A universal model of the process of defeating a moving armored target with directed fragmentation-beam shells has been built, which would provide preconditions for experimental studies into the effectiveness of various variants of the components of the artillery system for three-shot firing.
The execution of an artillery task is considered as a set of certain procedures characterized by the average value of its duration. They are dependent on the firing phases involving a prospective automatic gun and the explosive destruction of fragmentation-beam shells while the explosive destruction of each shell case is characterized by the self-propagation of the reaction of explosive transformations based on tabular data on the target. An indicator of the functionality of various design options for fragmentation-beam shells is the probability of causing damage by «useful fragments» in the vulnerable compartments of a combat armored vehicle.
Devising universal models for the process of shooting a moving armored vehicle forms preconditions for further full-time experiments in accordance with the design solutions defined as a result of modeling. It is possible to use the developed discrete-continuous stochastic model in other modeling tasks to determine the optimal value of defeat.
As regards the practical application of discrete-continuous stochastic models, one can argue about the possibility of reducing the cost of performing design tasks related to weapons by 25 % and decreasing the likelihood of making mistakes at the stage of system engineering design

Authors: Bilyk Olena , Burchenko Liudmyla , Kochubei-Lytvynenko Oksana , Bondarenko Yulia 
Published: December 2021

The object of research in this work is a baked product enriched with a mixture of sprouted grains, ground cinnamon, apple pectin, dry wheat gluten, ascorbic acid. Pastries occupy an important place in the production and sale of food products and have a high calorie content. To reduce the energy value of pastry products, it is proposed to replace wheat flour in the recipe with a mixture of germinated grains of wheat, oats, barley and corn. In this work, the properties of such mixtures were studied using the example of a mixture of the «CHOICE» company (Ukraine). The mixture of germinated grains of cereals of wheat, oats, barley and corn of this company is rich in dietary fiber, nonessential and irreplaceable amino acids, microelements and macroelements, vitamins.
It has been established that a rational substitution of premium wheat flour for a mixture of germinated grains in the recipe for pastry products is 50 %. Due to the germination process, a large amount of amylolytic and proteolytic enzymes accumulates in cereals, which impair the structural and mechanical properties of the crumb of pastry products, as a result of which the crumb of the product becomes sticky and wrinkled. The work was aimed at developing a multicomponent mixture to improve the quality of pastry products, the formulation of which includes a mixture of germinated grains. A «Solodok» multicomponent mixture has been developed, which has a positive effect on the organoleptic and structural-mechanical properties of the product crumb. The mixture contains safe food additives and ingredients: ground cinnamon, dry wheat gluten, apple pectin, ascorbic acid. It has been established that the introduction of the «Solodok» multicomponent mixture into the dough leads to the replacement of the fermentation process with the stage of sedimentation. The use of a multicomponent mixture leads to an improvement in the organoleptic characteristics of rich products, an increase in the specific volume of products, and an improvement in the development of the porosity of products. Adding a mixture of sprouted grains and a «Solodok» multicomponent mixture leads to a change in the traditional taste, the products acquire a pleasant aftertaste of sprouted cereals and cinnamon. The use of a mixture of germinated grains and a «Solodok» multicomponent mixture in the recipe for pastry products leads to a decrease in the energy value of pastry products in comparison with the control.

Published: December 2021

The research is devoted to the development of rules for the coordination of decisions in multichannel decision-making systems. Systems are considered that in an automated continuous mode process incoming signals from different channels and, on their basis, make the final decision. One of the most problematic stages in the operation of such systems is their own coordination of solutions received from different channels. There may be cases where different channels provide signals with opposite values. Then the choice of the decisive solution should depend on the reliability of the channels under consideration.
The object of research is the processes that take place during the coordination of decisions in multichannel decision-making systems. The development and implementation of such systems will allow in an automated mode to generalize the solution obtained through different channels, to increase the reliability and efficiency of the systems as a whole.
During the study, the following methods were used:
– a systematic approach – when analyzing the structure and functioning of multichannel one-stage decision-making systems;
– method of mathematical modeling – for formalizing the problem of coordinating decisions in multichannel decision-making systems;
– method of analysis – when developing rules for agreeing decisions.
The authors analyzed the structure of a one-stage multichannel decision-making system. The case is considered when the channels, based on the initial data entering the system, decide on the presence or absence of a certain fact. That is, the channels send signals from the set {True, False}.
In the study, decision rules for the coordination of decisions were developed, taking into account not only the signals received from different channels, but also the reliability of the channels themselves. As is usual in decision theory, different rules can give different results for the same initial data. The choice of the decision rule depends on the decision maker, its personal psychological qualities and the scope of the system.

Published: December 2021

Following the surface mining operations, large areas of agricultural land (arable land, meadows, etc.), forests, etc., are lost from the economic business in the county; all these lands, under adequate provisions of law must be reconstructed for agriculture and forestry.
The current concept of sustainable development presumes also an environmental protection strategy, designed today and accepted by the countries all over the world to maintain ecological balance at the global, regional and local level.
Research carried out on this theme aims to find the most effective forest species to make these areas as quickly as possible to enter the economic circuit.
Orientation regarding the afforestation of these areas depends largely on the ecopedologic zone, the material resulting from the exploitation of lignite and, first of all, available investments.
The present situation left by the surface mining operations within the Jilţ Basin shows that there are many areas of unproductive land that can not be included in the category of arable land. For this reason, research started aiming at the afforestation of these lands with different forest species. It was also considered the stabilization of sloping lands of these dumps in order to avoid the surprise of landslides in years with abundant precipitation.
Large areas of dumps were planted with Robinia pseudacacia, familia Leguminosae in both the Mining Jilţ Basin and the Mining Rovinari Basin, these land areas being well covered by forestry vegetation. But forestry does not mean only Robinia pseudacacia, familia Leguminosae and, for this reason, the species proposed in this paper include a large diversity and provide outstanding economic results.
