Published: April 2020

In the article, the authors conduct research on the problem of stabilization of dynamic parameters of an adaptive information-control system of a ground-based robotic complex in disturbed environment. The research concept is based on the latest trends in the development of third-generation robotics objects; on the definition of the robotic complex, as an autonomous substrate means of reproducing physical functions and automating the intellectual activity of a person in the process of active interaction of the component structures of the robotic complex with the environment; on the technology of integrating the ground-based robotic complex into the system of the highest level of hierarchy, in particular, in the system of providing or performing special tasks in the interests of the Armed Forces of Ukraine. The methodological preamble of the stated problems is being updated, the description of which occurs in relation to the model of substrate modification of the spatially distributed structure of the ground-based robotic complex.
The purpose of the study is related to the application of methodological description to the problem of stabilization of the dynamic parameters of the adaptive control system of the mobile substrate structure of a ground-based robotics complex in a disturbed environment.
Consequences of the presented description were announced, according to which stability is given priority as an integral-substrate property, which combines various types of stability of mobile spatially distributed structures of the ground robotic complex in time, and also characterizes their general structural and functional organization throughout operating time. The existence of the potential stability of the substrate structures of the ground-based robotic complex in cases of their resistance to the negative influence of external disturbances in time is confirmed. The absence of an inverse relationship was noted, that is, the component structures of the ground-based robotic complex that are resistant to external factors will not necessarily be stable.
The target result was obtained in the context of the general scientific paradigm and can serve as an application for the concept of ensuring the effective functioning of mobile spatially distributed structures of the ground-based robotic complex in the integrated project "object-system".
THE METHODICAL APPROACH TO THE MODELING OF REFURBISHMENT OF
RESTORED AND NON-RESTORATED SAMPLE OF ARMS AND MILITARY
EQUIPMENT

Published: April 2020

Today, all samples of modern weapons and military equipment (OVT) have high requirements for readiness for combat use, reliable operation during combat. Due to the continuous improvement of the OVT troops and the enhancement of their combat capabilities, much attention is paid to the reliability of these samples, since failure to perform them due to the failure of the OVT can lead to serious consequences in the operation (combat). Therefore, for a more realistic description of the level of failure of a renewable and non-renewable sample of military equipment, it is necessary to select and substantiate a more adequate variant of the mathematical model, which will take into account the influence of most factors influencing the sample of technology.
To describe the processes of equipment failure, under the assumptions defined in the article, it is proposed to use mathematical models of the type of queuing systems; This graph shows all possible transitions of this sample from one state to another, taking into account the specified operating conditions.
The authors propose that, unlike what is actually observed in the military, the value of the probability of failure- free operation of a renewable sample should be presented as a non-renewable sample of weapons and military equipment. This is not the case with the definition of a non-renewable (not repaired) specimen, when this determination is no longer related to the type of specimen, its components (they can be repaired), not to the repair, but to the specific purpose of military equipment. Therefore, if during the combat work of a sample of equipment his failure occurred, then given the final and long enough recovery time after failure occurs, he is considered unable to perform the combat task.
The main conclusion of the article is that, given the importance of military equipment, it is advisable to set them as a non-renewable sample of weapons and military equipment when substantiating the reliability of the design at the design stage. It can then be hoped that during the operation of the sample in the troops, the values of these indicators will be no worse than those recorded on the form, when weapons and military equipment are considered as a renewable sample.

Enhanced mnemonic discrimination for emotional memories: the role of arousal in interference resolution
Authors: Szőllősi Ágnes , Racsmány Mihály
Published: April 2020

In the present study we investigated the long-standing question whether and why emotionally arousing memories are more distinct as compared to neutral experiences. We assumed that memory benefits from the distinctiveness of emotional information, and that emotions affect encoding by reducing interference among overlapping memory representations. Since pattern separation is the process which minimizes interference between memory representations with similar features, we examined the behavioral manifestation of putative neural mechanisms enabling pattern separation (i.e. mnemonic discrimination) for emotionally arousing materials using the Mnemonic Similarity Task with negative, positive, and neutral images as stimuli. Immediately after incidental encoding, subjects were presented with stimuli they had seen at encoding and also with new items. Crucially, participants were also presented with lure images that were visually similar to ones they had seen before. Response options were old, new, and similar. Our results showed that individuals were better in discriminating between similar, emotionally arousing memories, when compared to the neutral stimuli. Moreover, this so-called lure discrimination performance was better for the negative images, than it was for the positive stimuli. Finally, we showed that the high arousing negative stimuli were better separated than the low arousing negative stimuli, and a similar pattern of results was found for the positive items. Altogether, these findings suggest that lure discrimination is modulated by arousal and not by valence. We argue that noradrenergic activity might facilitate interference resolution among memory representations with similar features, and that superior pattern separation might play a key role in memory enhancement for emotional experiences.
Implementación de la estrategia de servitización en las empresas manufactureras españolas
Authors: Castellón-Orozco Helen , Jaría-Chacón Natalia , Guitart-Tarrés Laura
Published: April 2020

La elevada competencia a la que se enfrentan las empresas hoy en día obliga a las organizaciones a establecer nuevas estrategias de diferenciación. De ello no se escapan las empresas manufactureras. En este sentido, las empresas manufactureras están añadiendo nuevas prestaciones adicionales a sus productos, tradicionalmente desarrolladas por empresas de servicios. La apuesta por complementar un producto fabricado con servicios adicionales que añadan valor (servitización) es una buena alternativa para conseguir la tan preciada diferenciación en las empresas manufactureras. A pesar de ello, hoy en día es todavía escasa la investigación que ha indagado empíricamente sobre la servitización que resulta ser una estrategia competitiva y rentable para un fabricante. Por este motivo, esta investigación analiza cómo la implementación de la estrategia de servitización afecta al rendimiento empresarial, es decir, cómo los resultados de la empresa se ven afectados por el hecho de que las empresas estén o no servitizadas. A partir del análisis de una base de datos de mil empresas manufactureras españolas y, tras el tratamiento estadístico realizado, se demuestra que las empresas altamente servitizadas obtienen mejores resultados empresariales que aquellas con un bajo nivel de implementación de esta estrategia. Con ello se concluye el efecto positivo, aunque no proporcional, que la oferta de servicios ejerce en los ingresos de las empresas y se demuestra que las compañías con un alto grado de servitización obtienen mejores resultados empresariales que aquellas con un bajo nivel de implementación.Palabras clave: Servitización; implementación; empresas manufactureras; servicio.

Published: April 2020

Las roturas de tuberías en redes de abastecimiento de agua provocan serios problemas para las compañías encargadas de su gestión. Con objeto de reducir el número de roturas inesperadas, se propone un método predictivo de clasificación de las tuberías que utiliza la regresión logística, junto con técnicas avanzadas de procesamiento de datos, como el equilibrado de clases o la validación cruzada. La metodología se ha aplicado al caso real de la red de abastecimiento de Sevilla. Los resultados muestran que podría llegar a predecirse el 85.9% de las roturas de tuberías, siendo 76.6% la precisión total del modelo.Palabras clave: Regresión logística; Red de abastecimiento de agua; Predicción de roturas de tuberías; Aprendizaje automático
A novel dry-blending method to reduce the coefficient of thermal expansion of polymer templates for OTFT electrodes
Authors: Ye Xiangdong , Tian Bo , Guo Yuxuan , Fan Fan , Cai Anjiang
Published: April 2020

Among the patterning technologies for organic thin-film transistors (OTFTs), the fabrication of OTFT electrodes using polymer templates has attracted much attention. However, deviations in the electrode alignment occur because the coefficient of thermal expansion (CTE) of the polymer template is much higher than the CTE of the dielectric layer. Here, a novel dry-blending method is described in which SiO2 nanoparticles are filled into a grooved silicon template, followed by permeation of polydimethylsiloxane (PDMS) into the SiO2 nanoparticle gaps. The SiO2 nanoparticles in the groove are extracted by curing and peeling off PDMS to prepare a PDMS/SiO2 composite template with a nanoparticle content of 83.8 wt %. The composite template has a CTE of 96 ppm/°C, which is a reduction by 69.23% compared with the original PDMS template. Finally, we achieved the alignment of OTFT electrodes using the composite template.

Published: April 2020

This research brief uses nationally representative data from the 2012/17 Beginning Postsecondary Students Longitudinal Study (BPS:12/17) to examine post-college transitions of US undergraduates into the skilled technical workforce (STW), defined here as workers in a collection of occupations that require significant levels of science, technology, engineering, and mathematics (STEM) knowledge but not necessarily a bachelor’s degree for entry. Thus far, empirical research on the STW has been limited by a dearth of data; however, based on newly available data from BPS:12/17, the findings in this report indicate that STW employment provides workers with above-median salaries, more equitable wages, a variety of benefits, and clear career paths. STW jobs attract diverse populations, especially those from underrepresented groups (e.g., Hispanics, individuals from low-income backgrounds, and those whose parents do not have college education). US community colleges and sub-baccalaureate programs play a large role in developing the STW.

Современный этап построения и совершенствования мелиоративных систем характеризуется переходом к передовым технологиям мониторинга и цифровизации. Достижение данной цели возможно только при существенном повышении качества управления гидромелиоративными оросительными системами (ГМС), в том числе за счет применения автоматизированных систем управления технологическими процессами (АСУ ТП). Основное предназначение систем АСУ ТП в гидромелиоративных системах можно определить как целенаправленное ведение технологического процесса подачи воды от водоисточника к конечному потребителю и обеспечение смежных и вышестоящих систем необходимой информацией. Для задач управления работой ГМС применяется пакет SCADA. SCADA (англ. Supervisory Control And Data Acquisition диспетчерское управление и сбор данных) программный пакет, предназначенный для обеспечения работы в реальном времени систем сбора, обработки, отображения и архивирования информации об объекте мониторинга или управления. Данное программное обеспечение устанавливается на компьютеры и для связи с объектом, использует драйверы ввода-вывода или специализированные серверы.

The current stage of construction and improvement of reclamation systems is characterized by a transition to advanced monitoring and digitalization technologies. Achieving this goal is possible only with a significant improvement in the quality of management of irrigation and drainage irrigation systems (HMS), including through the use of automated process control systems (ACS TP). The main purpose of automatic process control systems in irrigation and drainage systems can be defined as the targeted management of the technological process of supplying water from the water source to the final consumer and the provision of related and higher systems with the necessary information. For the tasks of managing the work of the HMS, the SCADA package is used. SCADA (English Supervisory Control And Data Acquisition - supervisory control and data collection) is a software package designed to provide real-time operation of systems for collecting, processing, displaying and archiving information about a monitoring or control object. This software is installed on computers and for communication with the object, uses I / O drivers or specialized servers.

Анализ водопользования рисосеющих агрокомплексов в зоне Нижней Кубани свидетельствует о напряженной водохозяйственной ситуации, обостряющейся в маловодные годы. Возникающие дефициты водообеспечения наносят существенный ущерб всем водопользователям и особенно отраслям сельского хозяйства. Предлагаемые авторами подходы совершенствования водообеспечения и водопользования оросительных систем базируются на разработке интегрированной системы управления распределением водных ресурсов и продуктивностью агромелиоративного комплекса. Новая технологии управления строится на двух взаимосвязанных оптимизационных задачах, решаемых в одном пространственном и временном формате: с помощью динамической гидравлической модели формируются и изучаются оптимальные варианты подачи поливной воды от водоисточников до орошаемого поля, а модели продуктивности отражают влияние параметров водоподачи на урожайность культур. Гидродинамическое моделирование позволяет формировать режимы работы водохранилищ и гидроузлов таким образом, чтобы с одной стороны обеспечить командные высоты на водозаборах, а с другой, удовлетворить конфликтующие интересы водопользователей, в том числе сельхозпроизводителей. Выработка приемлемого управленческого решения реализуется методами многокритериального анализа и теории компромиссов с ориентацией на прогноз недобора урожая в зависимости от варианта вододеления.

Analysis of water of rice-growing agricultural complexes use in the Lower Kuban region indicates a tense water management situation that worsens in low-water years. Occurring water supply deficits cause significant damage to all water users and especially to agricultural sectors. The approaches proposed by the authors to improve water supply and water use of irrigation systems are based on the integrated management system for the water resources distribution and productivity of the agro-reclamation complex development. The new management technology is based on two interrelated optimization problems that are solved in the same spatial and temporal format: optimal options for irrigation water supply from water sources to an irrigated field are formed and studied using a dynamic hydraulic model, and productivity models reflect the influence of water supply parameters on crop yields. Hydrodynamic modeling allows you to form reservoirs operating and hydroelectric facilities modes in such a way that, on the one hand, provide command heights at water intakes, and on the other, meet the conflicting interests of water users, including agricultural producers. The development of an acceptable management decision is realized by using the methods of multi-criteria analysis and the theory of trade-offs with a focus on the forecast of crop deficit depending on the water allocation option.

A Learner based Perspective on STEM Learning in AP Courses
Authors: Bao Albert
Published: April 2020

STEM fields are at the core of 21st Century Innovation. However only a small number of American students pursue STEM disciplines as their future careers. In high school, AP STEM courses provide unique opportunities to improve students’ awareness, interests, and access to STEM learning in the school environment. A positive experience in these AP courses can be a catalyst to shaping a student’s career interests and preferences towards STEM fields. However, these courses are also the most challenging among all high school curricula, and the situation is even more complicated by the shortage of teachers skilled in STEM subjects. It is then important to help students develop effective learning strategies for these courses. Through surveying high school students who have studied AP STEM courses, this study has found that students highly value learning physics with a concept-based approach, chemistry and calculus with a procedure-based strategy, and biology with a mix between memorization and concept. Additionally, students prepared best with a mix between concept-based activities, such as labs, and procedure-based activities, such as practice problems, in both physics and chemistry. Students who took biology found memorization-based preparations to be the most useful, and calculus was prepared best with procedure.

Estimation of distribution algorithms (EDAs) are successfully applied in the fields of bioinformatics for tasks such as gene structure analysis, protein structure prediction, and RNA secondary structure prediction. This paper proposes a new method, namely collaborative learning of estimation of distribution algorithms, or Co-EDAs, based on an estimation of distribution algorithm for RNA secondary structure prediction using a single RNA sequence as input. The proposed method consists of two EDAs with minimum free energy objective. The Co-EDAs use both good and poor solutions to improve the algorithm’s to search throughout the search space. Using information from poor solutions can indicate which area is unappealing to explore when searching with high-dimensional data. The Co-EDAs method was tested with 750 known RNA structures from RNA STRAND v2.0. That database includes data with more than 14 RNA types. The proposed method was compared to three prediction programs that are based on dynamic programming algorithms called Mfold, RNAfold, and RNAstructure. These programs are available as services on web servers. The results on average show that the Co-EDAs yields approximately 6% better accuracy than those competitors in all metrics.

TARGETING SMART SHOPPERS: A CROSS-COUNTRY MODEL
Authors: Gómez-Suárez Mónica , Quinones Myriam , Yagüe María Jesús
Published: April 2020

The purpose of this article is to provide a robust and consistent cross-country measurement of the smart-shopper self-concept. Drawing on existing single-country studies, our work extends research by validating a pioneer cross-country scale that measures the smart-shopping mechanism in a holistic manner. Survey data were collected from 1,233 shoppers from six different Western countries. Cross-country equivalence was assessed using multigroup confirmatory factor analysis using configural, metric, and factor variance invariance tests. The results indicate that the smart-shopper self-concept is a second-order construct comprising two dimensions: smartshopper-attributed behavior and smart-shopper feelings. Our findings also reveal that consumers in the different countries exhibit different degrees of smart-shopper self-concept and differ in their perceptions of the affective and behavioral responses generated during a smart purchase process. Marketing practitioners looking to target smart shoppers across multiple countries could build on the findings of this study to develop effective international segmentation and positioning strategies.
SHOULD GOLD BE HELD UNDER GLOBAL ECONOMIC POLICY UNCERTAINTY?
Authors: Qin Meng , Su Chi-Wei , Xiao Yi-Dong , Zhang Shuai
Published: April 2020

This paper investigates the ability of gold to hedge worldwide risks from the perspective of global economic policy uncertainty (GEPU). By applying the full- and sub-sample rolling-window bootstrap causality tests to analyze the dynamic interaction between GEPU and gold price (GP). It can be observed that gold can effectively hedge risks of GEPU during the Asian financial crisis, dot-com bubble and global economic crisis, but this result does not hold in non-crisis period. GEPU manifests two-way impacts on the GP in a few periods, this relationship between GEPU and GP being consistent with the hypothesis in the general equilibrium model, which states that changes in GEPU lead to the fluctuations of GP. In turn, GP has both positive and negative impacts on GEPU. In the current complex economic situation, governments and investors can consider gold to hedge risks of GEPU, especially during the economic crises.

The purpose of this study is to investigate the reaction of the insolvency rate to the various shocks in the economies of Romania and Spain through a Structural Vector Autoregressive model. Departing from quarterly data for 2008–2016, it was found that the future values of the insolvency rate are explained by the past values of the interest rate and the retail trade index, more precisely macroeconomic risk factors cost of debt and changing in demand are main responsible for the health of non-financial corporations sector. In contrast, the influence of the investment rate on insolvency rate is not predictable. In addition, both in Romania and in Spain the interest rate is the main determinant of the insolvency rate variation, beyond its own innovations, in horizons of over 2 quarters. These results were obtained under the circumstances that the analysed period was characterized by the Great Recession and its recovery. In this situation, firms faced a lesser demand as well as a tightening on the possibilities of obtaining the external funds they needed, not only to finance their expansion projects but even their daily operations. Consequently, many firms faced a negative environment that forced them to go out of the market.
SHORT-TERM AND LONG-TERM IMPACTS OF ECO-DRIVING ON DYNAMICS OF DRIVING BEHAVIOUR AND OPERATING PARAMETERS
Authors: Savković Tatjana , Miličić Milica , Tanackov Ilija , Pitka Pavle , Koleška Dejan
Published: April 2020

This paper shows the impact of eco-driving training course on driving behaviour of 7 drivers, analysing two internal
parameters: Scania Driver Support (SDS) parameter and Fuel Consumption (FC). Data were collected using Scania Fleet Management System
(Scania FMS) over a period of one-year (1 + 2 + 4 + 6 months during the 2015 and 2016). Data for these two parameters of all drivers were
recorded daily over a one-year period and calculated in average values on a monthly basis. A one-year cycle of average monthly ambient
temperatures of wider geographical region was adopted as the most important external parameter of impact on eco-driving benefits. Longitudinal
observation period is divided into: one month initial period of establishing the parameter values before the training (one month), short-term
with eco-driving (two months), short-term without eco-driving (four months) and long-term (six months). Significantly higher values of SDS
parameter (p < 0.05) and significant reduction of FC (p = 0.0310 < 0.05) were established with a higher average ambient temperature over
a short-term period. A partial increase of SDS parameter value (p < 0.10) was established over a long-term period but the level of FC reversed
to the values as before the training (p = 0.7554 > 0.05). The results indicate the potential of eco-driving training that manifests significantly
positive effects only in good driving conditions. With bad weather conditions that correlate with bad driving conditions, the effects of
eco-driving training are supressed with increased requirements for safer driving. Primary conclusion of the paper is that the eco-driving
training principles have an apparent positive effect on reduction of FC and CO2 emission but are at the same time sensitive to environmental
driving conditions.
Faint and Fading Tails: The Fate of Stripped H i Gas in Virgo Cluster Galaxies
Authors: Taylor Rhys , Köppen Joachim , Jáchym Pavel , Minchin Robert , Palouš Jan , Wünsch Richard
Published: April 2020

Although many galaxies in the Virgo cluster are known to have lost significant amounts of H i gas, only about a dozen features are known where the H i extends significantly outside its parent galaxy. Previous numerical simulations have predicted that H i removed by ram pressure stripping should have column densities far in excess of the sensitivity limits of observational surveys. We construct a simple model to try and quantify how many streams we might expect to detect. This accounts for the expected random orientation of the streams in position and velocity space as well as the expected stream length and mass of stripped H i. Using archival data from the Arecibo Galaxy Environment Survey, we search for any streams that might previously have been missed in earlier analyses. We report the confident detection of 10 streams as well as 16 other less-certain detections. We show that these well match our analytic predictions for which galaxies should be actively losing gas; however, the mass of the streams is typically far below the amount of missing H i in their parent galaxies, implying that a phase change and/or dispersal renders the gas undetectable. By estimating the orbital timescales, we estimate that dissolution rates of 1–10 M

yr−1 are able to explain both the presence of a few long, massive streams and the greater number of shorter, less-massive features.
