Calculating the Wasserstein Metric-Based Boltzmann Entropy of a Landscape Mosaic
Authors: Zhang Hong , Wu Zhiwei , Lan Tian , Chen Yanyu , Gao Peichao
Published: March 2020

Shannon entropy is currently the most popular method for quantifying the disorder or information of a spatial data set such as a landscape pattern and a cartographic map. However, its drawback when applied to spatial data is also well documented; it is incapable of capturing configurational disorder. In addition, it has been recently criticized to be thermodynamically irrelevant. Therefore, Boltzmann entropy was revisited, and methods have been developed for its calculation with landscape patterns. The latest method was developed based on the Wasserstein metric. This method incorporates spatial repetitiveness, leading to a Wasserstein metric-based Boltzmann entropy that is capable of capturing the configurational disorder of a landscape mosaic. However, the numerical work required to calculate this entropy is beyond what can be practically achieved through hand calculation. This study developed a new software tool for conveniently calculating the Wasserstein metric-based Boltzmann entropy. The tool provides a user-friendly human–computer interface and many functions. These functions include multi-format data file import function, calculation function, and data clear or copy function. This study outlines several essential technical implementations of the tool and reports the evaluation of the software tool and a case study. Experimental results demonstrate that the software tool is both efficient and convenient.
Channels’ Confirmation and Predictions’ Confirmation: From the Medical Test to the Raven Paradox
Authors: Lu Chenguang
Published: March 2020

After long arguments between positivism and falsificationism, the verification of universal hypotheses was replaced with the confirmation of uncertain major premises. Unfortunately, Hemple proposed the Raven Paradox. Then, Carnap used the increment of logical probability as the confirmation measure. So far, many confirmation measures have been proposed. Measure F proposed by Kemeny and Oppenheim among them possesses symmetries and asymmetries proposed by Elles and Fitelson, monotonicity proposed by Greco et al., and normalizing property suggested by many researchers. Based on the semantic information theory, a measure b* similar to F is derived from the medical test. Like the likelihood ratio, measures b* and F can only indicate the quality of channels or the testing means instead of the quality of probability predictions. Furthermore, it is still not easy to use b*, F, or another measure to clarify the Raven Paradox. For this reason, measure c* similar to the correct rate is derived. Measure c* supports the Nicod Criterion and undermines the Equivalence Condition, and hence, can be used to eliminate the Raven Paradox. An example indicates that measures F and b* are helpful for diagnosing the infection of Novel Coronavirus, whereas most popular confirmation measures are not. Another example reveals that all popular confirmation measures cannot be used to explain that a black raven can confirm “Ravens are black” more strongly than a piece of chalk. Measures F, b*, and c* indicate that the existence of fewer counterexamples is more important than more positive examples’ existence, and hence, are compatible with Popper’s falsification thought.

Published: March 2020

The continuous increase of the penetration of distributed generation in the distribution network poses more severe challenges for its full accommodation. In this context, an energy storage system can be installed to enhance the ability to accommodate renewable energy because of its high flexibility. However, the investment cost of brand new energy storage equipment is so high that the widespread application of storage system in the distribution system has been limited. This article proposes a method, which aimed at optimizing energy storage dispatching in a distribution network, and takes the use of second-use electric vehicles (EV) batteries into account. A calculation model of power battery second-use capacity was established, the upper and lower bounds of the initial capacity of second-use energy storage system (SUESS) can be determined after the reorganization of the retired batteries, and then a multi-objective optimal dispatching model for the distribution system with SUESS can be established with reference to the capacity attenuation model and the daily mileage statistics model of the electric vehicle. The case study results show that configured SUESS in the distribution network can not only meet the needs of the distribution network to fully accommodate distributed generation, but also delay the upgrade of the distribution network.

Authors: Saedi Sepehr , Oruc Seref
Published: March 2020

The current study investigates the effects of Fiber Reinforce Polymer (FRP) additive on the performance of Stone Mastic Asphalt (SMA) mixtures with SBS and Viatop Premium additives. The asphalt mixture used in the current study included SBS (Styrene-Butadiene-Styrene) additive modified at the rate of 5% according to the necessary preliminary studies, and some SMA mixture modified by adding FRP (Fiber Reinforced Polymers) additive prepared in dimensions of 5 cm in different proportions (0.3%, 0.5%, 0.7% and 0.9%). The mechanical properties of the mixtures were investigated, and the findings revealed that the SMA mixture; prepared by adding FRP additive, SBS modified bitumen, and Viatop Premium additive; increased the rutting, aging resistance and elasticity of SMAs. Moreover, load spread ability and fatigue life revealed an increase, whereas high temperature sensitivity and tendency to crack at low temperatures decreased throughout the study. The FRP contribution rate that improves the performance characteristics of the SMA mixture to the highest level was found to be 0.7%.

Authors: Soares Yago , Cargnin Elyff , Naccache Mônica , Andrade Ricardo
Published: March 2020

This work studies the influence of the concentration and oxidation degree on the rheological behavior of graphene oxide (GO) nanosheets dispersed on polyethylene glycol (PEG). The rheological characterization was fulfilled in shear flow through rotational rheometry measurements, in steady, transient and oscillatory regimes. Graphene oxide was prepared by chemical exfoliation of graphite using the modified Hummers method. The morphological and structural characteristics originating from the synthesis were analyzed by X-ray diffraction, Raman spectroscopy, thermogravimetric analysis, Fourier transform infrared spectroscopy, and atomic force microscopy. It is shown that higher oxidation times increase the functional groups, which leads to a higher dispersion and exfoliation of GO sheets in the PEG. Moreover, the addition of GO in a PEG solution results in significant growth of the suspension viscosity, and a change of the fluid behavior from Newtonian to pseudoplastic. This effect is related to the concentration and oxidation level of the obtained GO particles. The results obtained aim to contribute towards the understanding of the interactions between the GO and the polymeric liquid matrix, and their influence on the suspension rheological behavior.

Izazovi nove genetike u suvremenom društvenom i vrijednosnom kontekstu
Authors: Kutleša Mislav , Kral Dario
Published: March 2020

Rad proučava suvremeni napredak na području genetike koji zahvaljujući velikim probojima u znanstvenom razumijevanju uloge gena u živih bića i razvoju (bio)tehnologije nudi nove primjene i mogućnosti na području zdravlja i poboljšanja čovjeka. U radu se nastoji ove napretke promatrati u suvremenom društvenom i moralnom kontekstu koji se često tumači i razumije kroz pojam postmodernizma. Priznajemo velike potencijale novih (bio)tehnologija, ali upozoravamo kako, budući da spomenuti kontekst ne nudi jasno definirane etičke standarde kao ni jasan koncept čovjekove prirode, postoji znatan rizik zloporabe tih (bio)tehnologija. Ti rizici najčešće se povezuju s ugrožavanjem slobode i jednakosti, a nerijetko se dovode i u vezu s pitanjima smisla i statusa čovjeka kao osobe. Dapače, nastojimo ukazati kako upravo problemi i nerazumijevanja na ontološkom području prethode društvenim neredima. Imajući to na umu, ne mislimo kako nove (bio)tehnologije po sebi stvaraju nove opasnosti, koliko imaju potencijal naglasiti one koje su već prisutne. Kako nova genetika intervenira u samu arhitekturu života, stavljajući je na raspolaganje ljudskim rukama, sam život bi mogao postati tržišna i manipulativna roba. Odgovor na te moguće zloporabe nije u odbacivanju novih (bio)tehnologija, nego u prepoznavanju nedvosmislenog statusa čovjeka kao bića koje je vrijednost u sebi i za sebe, a koju je nemoguće prepoznati ako se zanemaruje transcendentna dimenzija čovjeka.

Published: March 2020

Objective,: In this randomized study, we evaluated two different doses of intrathecal (IT) morphine with bupivacaine for analgesia after transurethral resection of bladder (TUR-B).
Methods: Seventy-five patients were randomly divided into three groups. They were allocated to receive IT morphine (100 µg) with 12.5 mg 0.5% bupivacaine (Group 1), IT morphine (200 µg) with 12.5 mg 0.5% bupivacaine (Group 2), and IT 12.5 mg 0.5% bupivacaine without morphine (Group 3). Postoperative pain was evaluated by VAS during 24 h and each patient was given intravenous paracetamol and Dexketoprophen trometamol if pain severity was moderate.
Results: VAS scores were significantly lower in Groups I and II than Group III at 1h, 2h, 4h, 6h, 12h (p< 0.05) (Figure 1). The request for analgesia was significantly higher in Group III than the other two groups (p< 0.05). More patients reported postoperative nausea in Group II than the other two groups (p< 0.05) (Figure 2).
Conclusion: IT morphine (100 µg and 200 µg) with 12.5 mg 0.5% provided a significant reduction in postoperative pain scores compared to IT 12.5 mg 0.5% bupivacaine alone. IT morphine 100 µg provided comparable postoperative pain control with significantly lower side effects than IT morphine 200 µg after TUR-B.

Published: March 2020

The article considers the influence of technological steelmaking parameters in an oxygen converter on the oxygen content in steel before tapping. Today, CELOX is an effective, but at the same time expensive method for measuring the oxygen content in steel. The information obtained using this device allows you to accurately determine the ferroalloys consumption for deoxidation of steel. Since the oxygen content in steel before production directly affects the ferroalloys and aluminum consumption, necessary for steel deoxidation, the aim of this work was to create a mathematical model that allows determining the oxygen content in steel before tapping, taking into account the controlled melting parameters. The object of the study was a top blowing oxygen converter of 60 t capacity. The following analysis was carried out for 3PS steel grade. To create a mathematical model, the factors that have the greatest influence on the oxygen content in steel before tapping were previously selected by the method of correlation analysis. Such factors included the carbon, manganese, sulfur and phosphorus content in steel before tapping, its temperature and specific consumption of oxygen. Using the method of multiple regression analysis, a mathematical model was determined, which allows determining the oxygen content in steel before tapping at the end of each melt. Comparison of the actual data on the oxygen content in steel before tapping with the results of calculation using the model showed their high convergence, which confirms the adequacy of the obtained model. The application of the developed mathematical model for predicting the oxygen content in steel before tapping in a real metallurgical enterprise will allow reduce consumption of ferroalloys and alumina for deoxidation of crude steel.
Ways to improve the reliability of the nodes of the rolling mill

Published: March 2020

The performance of the crimping mill is determined by the speed of the pressure device. The main purpose of the pressure device is to regulate the relative position of the rolls, which is necessary to ensure the rolling of the profile of a given size and predetermined reductions, and in reversing mills, the distance between the rolls changes almost after each pass.An industrial survey of crimping rolling mills has shown that their reliability and durability significantly depend on the working capacity of the friction units, one of which is a screw pair of a pressure device. At this time, there is no information in the literature on the patterns of wear intensity of turns of screw pairs of rolling mills.Basically, increasing the resistance of nuts is done by balancing the load on the threads by changing the shape of the body of the nut. All these structural improvements of the nuts of the screw pair of the pressing mechanisms should be taken into account at the stage of designing the rolling stand, since changing the external shape of the nut can cause inevitable downtime of the production line associated with the coordination of seats in the bed of the rolling mill, which are unacceptable in the conditions of continuous production.In order to increase the working capacity of the screw pair of the pressing mechanism of the crimping mill, the task was set to analytically study the influence of the design of the threaded connection of the screw pair of the pressing mechanism on its efficiency.For crimping mills, in contrast to rolling a strip or sheet, more important is the speed of the pressure mechanism. An increase in the thread pitch leads to an increase in the efficiency of the helical gear, but the use of a thread with a large pitch has limitations associated with the displacement of the average diameter to the projections of the thread, reducing its reliability and the accuracy of the gap between the rolling rolls. Screw thread - single thrust resistant. If you thread according to current standards, only the friction angle in the thread remains - a factor that can be varied with an increase in the efficiency of the screw pair.The decrease in the angle of friction in the thread, with its proportional dependence on the coefficient of friction-slip, causes a significant increase in the efficiency of the screw pair. Reducing the coefficient of friction-slip is possible by the correct selection of rubbing pairs and the timely supply of lubricant to the friction zone. Since in the process of rolling technological operations, moments may occur when the lubricant is not supplied to the friction zone, one of the ways to increase the efficiency of the threaded joint should be the option of the correct selection of friction pairs that are less affected by the lack of lubricant supply to the friction zone.
Binarization methods and investigation of their influence on the fractal dimension of functional coatings
Authors: Zhurba Anna , Gasik Michail
Published: March 2020

An essential element of fractal analysis of functional coatings is the fractal dimension, which is an important quantitative characteristic. Typically, coating images are represented as colored or halftone, and most fractal dimension algorithms are for binary images. Therefore, an important step in fractal analysis is binarization, which is a threshold separation operation and the result of which is a binary image.The purpose of the study is to study and program the methods of image binarization and to study the influence of these methods on the value of fractal dimension of functional coatings.As a result of the binarization threshold, the image is split into two regions, one containing all pixels with values below a certain threshold and the other containing all pixels with values above that threshold. Of great importance is the determination of the binarization threshold.The study analyzed a number of functional coating images, determined the fractal dimension of the image by the Box Counting method at different binarization thresholds and when applying different binarization methods (binarization with lower and upper threshold, with double restriction, and the average method for determining the optimal binarization threshold) images. The Box Counting method is used to depict any structure on a plane. This method allows us to determine the fractal dimension of not strictly self-similar objects. Each image binarization method is used for different types of images and for solving different problems.As a result, the methods of image binarization were developed and implemented, the fractal dimension of binary images was calculated, and the influence of these methods on the value of fractal dimension of functional coatings was investigated.The surfaces of composite steel structure, metallic porous materials, and natural cave structures are analyzed.
ACCURACY WALL SICKNESS OF HOT-DEFORMED PIPES STATISTICAL ANALISIS
Authors: Sobolenko Oleksandr , Drozhzha Petro , Dorosh Nataliia , Petrechuk Lina
Published: March 2020

Pipe-rolling units with an automatic mill are a aggregate production complex that produces hot-rolled pipes of various sizes. The technological process of seamless pipes production, has many stages: flashing the billet into a sleeve, longitudinal rolling in gauge, running in a oblique rolling mill, calibrating and reducing the diameter. Each stage significantly affects the accuracy of the geometric dimensions of the pipes. One of the main parameters characterizing the accuracy of the pipes is their transverse difference namely the size and the nature of the distribution of the pipe wall thickness in the cross section. A significant reserve for saving metal is increasing the accuracy of seamless pipes to avoid different pipe wall thickness. Different pipe wall thickness makes it difficult to get quality pipe screw-thread.The conditions of metal deformation at an injection molding machine with an automatic machine do not exclude the presence of fluctuation of the pipe wall thickness. The best characteristic of the accuracy of finished pipes will be the knowledge of quantitative indicators of the transverse difference of their end sections. The purpose of this work is to determine the variation in wall thickness of hot-rolled casing by means of mathematical statistics methods.The use of statistical data processing methods makes it possible to predict the seamless pipe difference indicator. A statistical analysis of the wall thickness indicator of the end sections showed a high ratio of wall thickness symmetry. An effective way to minimize the symmetric difference component is to optimize the deformation modes along the pipe wall. In this case, a graphical analysis of the distribution of wall thickness showed that the actual difference varies in stochastic dependence. To clarify the general form of the random periodic component of such a dependence, it is advisable to apply methods of harmonic analysis, which will allow us to develop a mathematical model for determining the accuracy of pipes.

Приведены результаты теоретических и опытно-промышленных исследований на стане 1680 в период внедрения непрерывной прокатки в трех парах черновых клетей. С помощью разработанной математической модели, составленной в абсолютных значениях переменных, раскрыт характер формирования межклетевых натяжений при заполнении толстой полосой каждой из пар черновых клетей и раскатом непрерывной шестиклетевой группы. Учет упругих крутильных колебаний линий привода позволил прояснить роль высокочастотной составляющей в переходных процессах и повысить точность определения динамических нагрузок на 15-20 %. Раскрыт процесс транспортного переноса (запаздывания) толщины полосы от клети к клети в взаимосвязи с межклетевыми натяжениями. Показана количественная связь формирующихся натяжений по мере заполнения непрерывной группы полосой с образованием утолщенных концевых участков готового проката. Установлены такие сочетания возмущений (по толщине и температуре раската), которые приводят к существенному увеличению межклетевых натяжений и разнотолщинности или их уменьшению. Путем опытно-промышленных измерений установлены особенности взаимодействия черновых клетей через толстую полосу.

Published: March 2020

The problem of blind signal separation, namely, the separation of a vocal track from a finished mixed recording, is considered. The purpose of the research is to isolate the characteristics of the vocal signal on the basis of existing methods and software. The existing methods of vocal selection are analyzed: frequency filtering methods, phase subtraction and methods based on artificial intelligence systems. Features of application of each method, their advantages and disadvantages are highlighted. A comparative analysis of the methods considered using Spleeter and iZotope RX7 software is carried out. Artificial intelligence methods are much better at solving the problem, but they are not satisfactory. There are distortions in the timbre of the voice and foreign noises from the remnants of other instruments. Based on this, we conclude that the existing methods of isolating the vocal are not effective due to the lack of consideration of the peculiarities of the timbre of the voice in a particular musical composition.

В статье рассматривается задача создания структуры вычислительного кластера с высокой производительностью и относительно низкой стоимостью на основе широкодоступных одноплатных миникомпьютеров для совмещения задач бортового вычислителя, вычислителя системы управления ориентацией и стабилизацией (СУОС), а также вычислителя для системы полезной нагрузки в одной системе.Предложена кластерная система бортового компьютера (БК), основанная на одноплатных компьютерах, которая позволяет распределить вычислительную нагрузку между несколькими узлами и обеспечить тройное резервирование.Кластерную систему на основе COTS (компонентов готовых к использованию) компонентов предлагается использовать в качестве БК университетского наноспутника дистанционного зондирования Земли для повышения производительности вычислений и снижения стоимости компонентов.

Yet Another Inquiry into the Trustworthiness of Eighteenth-Century Bills of Mortality: the Newcastle and Gateshead Bills, 1736–1840
Authors: Butler Graham
Published: March 2020

This note is a preliminary analysis of the Newcastle and Gateshead Bills of Mortality, a hitherto unused source for understanding some of the most significant aspects of vital registration and burial practices in the North East's capital, c. 1736–1840. The Bills are annual totals of the number of burials and baptisms which took place in all of the ancient Anglican parishes in Newcastle and Gateshead. One of the most lucid aspects of the Bills is that they recorded the number of burials which took place in the 'infamous' un-consecrated burial ground of Ballast Hills located on the outskirts of the east-end of the town. Attention here is given to the initial accuracy of the Bills by focusing upon All Saints parish in Newcastle which accounted for approximately 50 per cent of the town's total population over the entire period. Here the data revealed in the Bills are compared directly with the burials which were registered by the parish clerk in All Saints. The major finding of this preliminary study is the huge discrepancy between the number of reported burials and the number of baptisms which took place in All Saints over time. The Bills also provide a fully documented account of the impact of Ballast Hills and the apparent “export in corpses” which was clearly taking place on a large scale. By the 1770s–1790s, this one burial ground alone, was consuming roughly 60–70 per cent of the town's dead population. The reasons behind this phenomenon are discussed by looking specifically at the possible impact of religious dissent, burial costs and burial space in the town. The note concludes that while this preliminary analysis is revealing, more work needs to be done which would involve a fuller analysis of all of the parishes recorded in the Bills as well as looking more closely at the registration of baptisms, stillbirths and the heavy “traffic in corpses” which was clearly a major defect of vital registration in Georgian Newcastle.
Conceptual clarification of evolution as an interdisciplinary science
Authors: Hanisch Susan , EIrdosh Dustin
Published: March 2020

Evolutionary theory in the 21st century has been embraced, albeit with varying degrees of controversy and consensus, across wide ranging disciplines. From biology and anthropology, to medicine, psychology, economics, sustainability science, computer science, and many more, core concepts of heritable variation and selection have been utilized by scientists across academia to understand change in the natural and social world. This article aims to provide evolution educators with a short review of current discourse in evolution science and a conceptual clarification of core concepts in evolutionary theory, in the service of promoting deeper and transferable understanding of these concepts in evolution education.
Carnaval e “A História que a História Não Conta”
Authors: Jesus Anna Cristina de Almeida
Published: March 2020

A Estação Primeira de Mangueira foi campeã dos desfiles do Carnaval de 2019 do Rio de Janeiro com o enredo “História para ninar gente grande”. Após a verificação de 1.592 sambas de enredo, dos carnavais cariocas de 1939 a 2019, este artigo demonstra que foram apresentadas, em 43 composições anteriores, de escolas diversas, perspectivas semelhantes às que constam no samba-enredo da Verde e Rosa. São obras que exaltam as contribuições de negros, indígenas e populares para a História do Brasil; elencam personalidades relevantes como “outros heróis”; desconstroem a contribuição dos heróis “clássicos” da pátria; e realizam críticas à sociedade brasileira, suas mazelas e seu(s) governo(s). Finalmente, elencamos as oito principais composições que ilustram essas propostas. O objetivo é relacionar a produção cultural carnavalesca às questões do seu tempo, destacando a importância do festejo para a cultura nacional.
Por uma Agenda de Festas

Published: March 2020

Dias de Gala, dias de festa nacional e dias santos compunham os dias reconhecidos como feriados durante o Brasil Império. Os feriados estavam entre os regentes do cotidiano no Recife Oitocentista, somado a esses numerosos dias oficiais para festejar, havia muitos outros em que a sociedade festejava. Escolher um feriado é um acontecimento muito complexo, envolve múltiplos sujeitos e questões. Em tempos de revisão do antigo regime, as festas precisavam expressar ou dialogar com os novos valores liberais e civilizatórios. Havia uma tentativa de diminuição do número de festas durante o ano por parte do Estado Nacional e da Igreja para controlar o tempo em que as festas deveriam oficialmente ter maior importância no cotidiano e na organização social.

Published: March 2020

O objetivo da pesquisa foi analisar, por meio de estratégias textuais, como se deu o uso político-ideológico do futebol na propaganda do governo federal "Isso é ser brasileiro. Essa é a Copa das Copas", veiculada na mídia televisiva, em 2014. Para isso, utilizamos os pressupostos do Physical Cultural Studies. A análise evidenciou que o esporte foi utilizado pelo governo federal com fins político-ideológicos. Assim, identificamos o reforço ao sentimento de patriotismo, a presença de intencionalidades visando promover aceitação da realização da Copa do Mundo no Brasil e, relações intertextuais que visavam transmitir uma ideia positiva do governo petista, partido então no poder do Estado e que concorreria à reeleição em 2014.
