Authors: Артёмов Н. , Калюжный А. , Романашенко А. , Колодяжный И.
Published: January 2021

Велика нерівномірність розсіву добрив відцентровими розкидачами пояснюється наступними причинами. По-перше це прояв технічних особливостей розкидання добрив відцентровим органом. По-друга це вплив фізико-механічних властивостей сипких добрив і третя причина велика неточність подання добрив через дозуюче вікно пристрою на розкидаючий диск Встановлено, що відцентровим дисковим розкидачем сипких мінеральних добрив властива природна нерівномірність розподілення добрив по поверхні поля, яка значно посилюється сегрегацією часток добрив на стадії їх польоту. Так досягти підвищення якості розподілу можна за рахунок істотного зменшення ширини розкидання добрив кожним окремим диском, зменшивши його діаметра. З метою покращення якості розсіву добрив запропоновано багатодисковий пристрій для розсіву мінеральних добрив по поверхні поля. Пропонується пристрій виконати у вигляді самостійних, функціонально незалежних модулів. Кожен модуль складається з трьох незалежних блоків: місткості для добрив з мішалкою; горизонтального дискового дозатора з калібрувальними отворами; горизонтальної тарілки розкидача. Кожен з блоків забезпечений індивідуальним електроприводом. Таке виконання дає можливість здійснювати регулювання дозування добрив на розкидаючу тарілку і дальності розкиду добрив, шляхом індивідуальної установки певного числа обертів обертання диска дозатора і тарілки розкиду добрив. Дана компонування не обмежувати їх число та місцем закріплення на рамі, а ширина захопленню агрегату буде регламентуватися тільки їх кількістю і дальністю розкиду добрив кожним індивідуальним блоком. У результаті досліджень макетного зразка дозатора з активним примусово- порційним дозуванням сипких мінеральних добрив отримана його задовільна роботоздатність. Але дослідження показали, що величина заповнення отворів диска залежить від обертів його обертання і від розмірних параметрів вікон завантаження і вивантаження, а також наявності бордюру розташованого у кінці завантажувального вікна. Бордюр запобігає зрушенню шарів добрива відносно один до одного і поверхні диска, що обертає, тим самим покращуючи заповнення отворів добривами.
The role of sports diplomacy in recognition of newly created states
Authors: Okladnaya Marina , Shchehlakov Ivan
Published: January 2021

Problem setting. Sport becomes an important part of modern life. Nowadays there are many international sports competitions and events, where unrecognized states take part. In connect with this, such cases have an impact on society and social media. Consequently, there is a question of the impact of sports diplomacy on recognition of states and its importance on this procedure.
Target research. To identify the impact of sport diplomacy on the recognition of newly created states.
Analysis of recent researches and publications. The object of research was recognition in international law of a large number of both domestic and foreign scientists, among which, Telipko V.E., Ovcharenko A.S., Feldman D.І., Janatayev H.M., whose doctrinal developments provide an important theoretical basis for studying the issue of the impact of sports diplomacy on recognition of states.
Article’s main body. Forms of recognition of states were identified in the article. It was determined that there are three form of recognition: de jure, de facto and ad hoc. Definition of sports diplomacy was given. It was proposed that in ad hoc recognition as the representative of the state should be considered not only a representative of the Government, but also other persons with official powers given by authorities. Cases of using sports diplomacy were analyzed. Usually a platform of sports diplomacy is different sport events where unrecognized states take part. The examples of such events are participation of Kosovo Republic in Olimpic Games in Brazil, Kosovo’s entry into FIFA, the football match between Kosovo Republic and Ukraine and others. In this way, sports representatives of the states enter into the negotiations and establish relationships between the states, which don’t recognize each other. It was found that sports diplomacy can be a way of ad hoc recognition.
Conclusions and prospects of development. Sports diplomacy is a type of diplomacy, which purpose is to provide state foreign policy in the field of sports. However, sports diplomacy doesn’t cause de jure or de facto recognition of states; it can influence on recognition of the states by helping to build relationships between them.

Authors: Фомин Леонид Викторович
Published: January 2021

Исследуется длительное разрушение оболочки и пластины при ползучести в активной среде в условиях нестационарного сложного напряженного состояния. Учет влияния среды на время до разрушения осуществляется с помощью введения в определяющие и кинетические дробно-линейные соотношения функции от интегрально средней концентрации среды. Проведено сравнение времен до разрушения при использовании скалярного и векторного параметров поврежденности. Определены особенности использования дробно-линейной модели для описания процессов длительного разрушения.

The long-term destruction of the shell and plate during creep in the active medium under the conditions of an unsteady complex stress state is investigated. The influence of the medium on the time to fracture is taken into account by introducing a function of the integral average concentration of the medium into the constitutive and kinetic linear-fractional relationships. Comparison of the times to failure using the scalar and vector damage parameters is carried out. The features of using a linear-fractional model to describe long-term fracture processes are determined.
Metaharmonic potentials in mechanics of micropolar media
Authors: Радаев Юрий Николаевич
Published: January 2021

Рассматриваются дифференциальные уравнения для потенциалов перемещений и микровращений, замещающие связанные векторные дифференциальные уравнения линейной теории микрополярной упругости. Исследуются только гармонические зависимости от времени. Опираясь на представление векторов перемещений и микровращений с помощью четырех винтовых векторов, обеспечивающее выполнимость связанных векторных дифференциальных уравнений линейной теории микрополярной упругости, получены новые представления в терминах двух метагармонических векторных полей. Проблема нахождения вихревых составляющих перемещений и микровращений приводится к решению двух несвязанных между собой векторных метагармонических уравнений. Часто указанные уравнения могут быть решены разделением пространственных переменных. Поэтому полученные представления могут находить применение в прикладных задачах механики деформируемого твердого тела, связанных с распространением гармонических волн перемещений и микровращений, характеризующихся заданным азимутальным числом, вдоль длинных цилиндрических волноводов.

The coupled vector differential equations of the linear theory of micropolar elasticity formulated in terms of displacements and micro-rotations are studied. A harmonic dependence of the physical fields on time is assumed. By employing the displacements and micro-rotations representation formula in the terms of four screw vectors a new representation based on two metaharmonic vectors are obtained. Thus the problem of determination of the vortex parts of the displacement and micro-rotation fields is reduced to solution of two uncoupled vector metaharmonic equations. The latter can be oftenly solved by the separation of variables technique. For this reason obtained results can be applied to various problems of the micropolar elasticity related to harmonic wave propagation in waveguides. In particular this is true for waves of a given azimuthal number in a long cylindrical waveguide.

Одним из факторов успешного развития туризма и повышения туристкой привлекательности региона является формирование благоприятной городской среды. Анализ показателей, характеризующих уровень развития городской среды городов Волгоградской области, выявил, что в 2018 году ни один город региона не набрал необходимое количество баллов для присвоения статуса «Город с благоприятной городской средой», а в 2019 г. в число таких городов вошел Камышин. Однако в настоящее время в регионе активно реализуются проекты по благоустройству территорий и используются практики развития объектов туристско-рекреационного назначения, апробированные в регионах, достигших существенных успехов в развитии туризма: реализуется проект «Создание современного туристско-рекреационного кластера в пойме р. Царица «Новая пойма»; пять городов региона завоевали гранты Всероссийского конкурса благоустройства (Михайловка, Урюпинск, Николаевск, Палласовка и Петров Вал); благоустройство парка «Заречный» г. Фролово.

One of the factors for the successful development of tourism and increasing the tourist attractiveness of the region is the formation of a favorable urban environment. An analysis of indicators characterizing the level of development of the urban environment of the cities of the Volgograd region revealed that in 2018 not a single town in the region scored the required number of points to be awarded the status of "City with a favorable urban environment", and in 2019 Kamyshin was included in the number of such towns. However, at present, the region is actively implementing projects of the area improvement and the practice of developing objects for tourist and recreational purposes, tested in regions that have achieved significant success in the development of tourism, are using: the project “Creation of a modern tourist and recreational cluster in the floodplain of the river Tsatitsa "New floodplain"; five cities in the region won grants from the All-Russian landscaping competition (Mikhailovka, Uryupinsk, Nikolaevsk, Pallasovka and Petrov Val); a large improvement project in the city of Frolovo has been completed.

Published: January 2021

This study shows that the model of assessing the opportunities for innovation activity of enterprises is multivariate and interrelated with such macroeconomic regulators of Ukraine’s development as competitive attractiveness of the country, favorable conditions for doing business in the country and innovation activity of enterprises. The use of a three-dimensional matrix of indicators to assess Ukraine’s competitive attractiveness allowed us to evaluate the significant impact of changes in Ukraine’s Global Innovation Index on the innovation activity of enterprises for the period 2014–2019. Moreover, the greater the value of the indicator of the state’s innovation potential is, the higher the level of innovation activity in the country becomes, which significantly increases the positive image of Ukrainian entrepreneurs at the global level and acts as a “green light” for foreign investors. Given the wide range of parameters that must be taken into account in an integrated assessment of innovation activity of an enterprise, we have used the method of component analysis. The uniqueness of an integrated assessment of innovation activity of an enterprise is carried out in accordance with the concept of value formation of innovations and it is tested on the example of Ferrotrading LLC. The effectiveness of the study consists in the fact that the selected sub-indicators for assessing the innovation activity of the studied enterprise (innovation resources, innovation competencies and innovation abilities) greatly complement the assessment of the opportunities for innovation activity in the proposed model. The conducted study has theoretical and practical significance. It can be used as a basis for further research in this area and can be employed by governments to make management decisions on increasing the innovation activity of business and the state as a whole.
THE ANALYSIS OF BARRIERS TO BIM IMPLEMENTATION FOR INDUSTRIALIZED BUILDING CONSTRUCTION: A CHINA STUDY
Authors: Wu Ping , Jin Ruoyu , Xu Yidong , Lin Feng , Dong Yiting , Pan Zhihong
Published: January 2021

The emerging Building Information Modeling (BIM) can better promote the development of building industrialization, with data integration between information-rich building models and business processes. However, the practical implementation of BIM still faces barriers. Existing studies have discussed these barriers extensively, but the research on the barriers to the implementation of BIM amid building industrialization in China is inadequate. In this study, 23 barriers were identified through literature review. A questionnaire survey approach was used to collect data from various parties. Factor analysis methods were used to process and rank barrier factors for BIM applications in the context of industrialized building. Based on the analysis of each factor, analytic hierarchy process was adopted to identify the key barriers to the implementation of BIM for industrialized building construction. The study concluded that the main barriers for BIM implementation for industrialized building were capital-related factors and the lack of support from owners. This study proposes that in addition to governmental policy support for BIM and multi-stakeholder engagement, companies should also organize experts to effectively evaluate the risks of applying BIM. Overall, this study provides suggestions on construction organizational transformations in the roadmap of moving towards digital-driven building industrialization.
Imaging Evidence for Solar Wind Outflows Originating from a Coronal Mass Ejection Footpoint
Authors: Lörinčík Juraj , Dudík Jaroslav , Aulanier Guillaume , Schmieder Brigitte , Golub Leon
Published: January 2021

We report on Atmospheric Imaging Assembly observations of plasma outflows originating in a coronal dimming during a 2015 April 28 filament eruption. After the filament started to erupt, two flare ribbons formed, one of which had a well-visible hook enclosing a core (twin) dimming region. Along multiple funnels located in this dimming, a motion of plasma directed outward started to be visible in the 171 and 193 Å filter channels of the instrument. In time–distance diagrams, this motion generated a strip-like pattern, which lasted for more than 5 hr and whose characteristics did not change along the funnel. We therefore suggest the motion is a signature of outflows corresponding to velocities ranging between ≈70 and 140 km s−1. Interestingly, the pattern of the outflows and their velocities were found to be similar to those we observed in a neighboring ordinary coronal hole. Therefore, the outflows were most likely a signature of a coronal mass ejection–induced solar wind flowing along the open-field structures rooted in the dimming region. Further, the evolution of the hook encircling the dimming region was examined in the context of the latest predictions imposed for 3D magnetic reconnection. The observations indicate that the filament’s footpoints were, during their transformation to the dimming region, reconnecting with surrounding canopies. To our knowledge, our observations present the first imaging evidence for outflows of plasma from a dimming region.
Nebular Models of Sub-Chandrasekhar Mass Type Ia Supernovae: Clues to the Origin of Ca-rich Transients
Authors: Polin Abigail , Nugent Peter , Kasen Daniel
Published: January 2021

We use non-local thermal equilibrium radiative transport modeling to examine observational signatures of sub-Chandrasekhar mass double detonation explosions in the nebular phase. Results range from spectra that look like typical and subluminous Type Ia supernovae (SNe) for higher mass progenitors to spectra that look like Ca-rich transients for lower mass progenitors. This ignition mechanism produces an inherent relationship between emission features and the progenitor mass as the ratio of the nebular [Ca ii]/[Fe iii] emission lines increases with decreasing white dwarf mass. Examining the [Ca ii]/[Fe iii] nebular line ratio in a sample of observed SNe we find further evidence for the two distinct classes of SNe Ia identified in Polin et al. by their relationship between Si ii velocity and B-band magnitude, both at time of peak brightness. This suggests that SNe Ia arise from more than one progenitor channel, and provides an empirical method for classifying events based on their physical origin. Furthermore, we provide insight to the mysterious origin of Ca-rich transients. Low-mass double detonation models with only a small mass fraction of Ca (1%) produce nebular spectra that cool primarily through forbidden [Ca ii] emission.

Using Human-Centered Trade Policies to End Violence in Africa
Authors: Pellegrino Silvia
Published: January 2021

International organizations have been discussing the issue of poverty and development in Africa since the end of colonialism. However, results have been inadequate, and the majority of the African population still lives in poverty and lacks access to healthcare, education, and safety. This chapter analyzes the benefits of preferential trade agreements in supporting both economic and social development. PTAs that are conditional to peace and human rights protection can be the economic tool to end violence, corruption, and bad government in Africa. Foreign economic policy in the past has left African countries indebted to the West and in competition with much older, more developed economies. This chapter discusses how the recently negotiated African Continental Free Trade Area can strengthen intracontinental trade. The agreement, if managed correctly, has the potential to grow the African economy massively and help lift people out of poverty while enforcing an end to violence from state-actors across the continent.

Published: January 2021

It has been shown that reproductive activity is responsive to changes in the physical, psychosocial, and chemical environments. Occupational exposure has been identified to a wide range of putative hazards and adverse reproductive outcomes, or fertility. Such risks include the physical environment such as VDT and noise, as well as psychosocial stress and chemical agents. Some of these may have a direct or indirect effect on IVF outcomes. Psychosocial factors such as inadequate coping mechanisms, anxiety and/or depression are related to a lower incidence of IVF pregnancy. In this chapter the authors focus on the difficulties involved in linking exposure to putative hazardous substances to adverse reproductive outcomes in environmental and occupational settings, particularly the effectiveness of IVF procedures.
An Authopreter Narrative

Published: January 2021

Few people can show mathematics, physics, chemistry, geometry, or foreign language among the lessons they love in the educational process. It is no doubt that these lessons, which are difficult to understand and challenging to solve, still maintain their vitality in memories. Apart from these well-known essential areas, it is undeniable that among the new branches of science that developed in the 20th century, one is least as scary as the others. Semiotics (or semiology) is one of the problematic fields with its sophisticated theories in the 19th century until Arthur Asa Berger applied the edutainment (learning by fun) method to semiotics by his work “Saussure Suspects.”
The True-Based Narrative
Authors: Taskiran Meliha Nurdan , Kara Murvet
Published: January 2021

In 1946, John Hersey, an employee of The New Yorker magazine, proposed the reality of the bomb that was thrown into Hiroshima for the agenda, and interviewed six coincidental survivors in the area and published the records within the frame of a truth-based narrative form. This work, which may be considered as a product of ‘literary journalism' or a reflection of ‘transmedia' or a ‘cross-media', is a true-based narrative in which six survivors' dramatic lives are constructed and embedded successfully. The study aims to describe and analyze the narrative structures in which the author tries to influence people in Hiroshima book, and the relationship between these structures will be tried to be revealed through narrative analysis, and a certain contribution to the narrative literature is targeted as well.
The World Has Been Naked

Published: January 2021

After the WikiLeaks incident, the world today is under the shock of the document. Since the moment of the invention of writing and the entry of man in historical times, the document has remained in the context of the closeness of holiness. Yes, human history is witnessing the leaking of more documents of the utmost importance, but the disclosure of this speed and free and direct and defamation only besieged the documents and stamps them with the symbolism missing, after the overthrow of the status of dear and beloved, and disperses prestige on the web platform. It is a departure from the meaning for which the document was historically designed. What was private became commonplace in a confusing way, and it was a secret exposed, and what was stored for 30 years or more, according to the value of the document and its effects, was public before reaching the decision-maker.

Published: January 2021

The exciting new features, such as advanced driver assistance systems, fleet management systems, and autonomous driving, drive the need for built-in security solutions and architectural designs to mitigate emerging security threats. Thus, cybersecurity joins reliability and safety as a cornerstone for success in the automotive industry. As vehicle providers gear up for cybersecurity challenges, they can capitalize on experiences from many other domains, but nevertheless must face several unique challenges. Therefore, this article focuses on the enhancement of state-of-the-art development lifecycle for automotive cyber-physical systems toward the integration of security, safety and reliability engineering methods. Especially, four engineering approaches (HARA at concept level, FMEA and FTA at design level and HSI at implementation level) are extended to integrate security considerations into the development lifecycle.
Socio-Technical SIEM (ST-SIEM)
Authors: AlSabbagh Bilal , Kowalski Stewart
Published: January 2021

This article discusses the design and specifications of a Socio-Technical Security Information and Event Management System (ST-SIEM). This newly-developed artifact addresses an important limitation identified in today incident response practice—the lack of sufficient context in actionable security information disseminated to constituent organizations. ST-SIEM tackles this limitation by considering the socio-technical aspect of information systems security. This concept is achieved by correlating the technical metrics of security warnings (which are generic in nature, and the sources of which are sometimes unknown) with predefined social security metrics (used for modeling the security culture of constituent organizations). ST-SIEM, accordingly, adapts the risk factor of the triggered security warning based on each constituent organization security culture. Moreover, the artifact features several socio-technical taxonomies with an impact factor to support organizations in classifying, reporting, and escalating actionable security information. The overall project uses design science research as a framework to develop the artifact.

Due to the significance of image data over the scalar data, the camera-integrated wireless sensor networks have attained the focus of researchers in the field of smart visual sensor networks. These networks are inexpensive and found wide application in surveillance and monitoring systems. The challenge is that these systems are resource deprived systems. The visual sensor node is typically an embedded system made up of a light weight processor, low memory, low bandwidth transceiver, and low-cost image sensor unit. As these networks carry sensitive information of the surveillance region, security and privacy protection are critical needs of the VSN. Due to resource limited nature of the VSN, the image encryption is crooked into an optimally lower issue, and many findings of image security in VSN are based on selective or partial encryption systems. The secure transmission of images is more trivial. Thus, in this chapter, a security frame work of smart visual sensor network built using energy-efficient image encryption and coding systems designed for VSN is presented.

The healthcare industry has been facing a lot of challenges in securing electronic health records (EHR). Medical images have found a noteworthy position for diagnosis leading to therapeutic requirements. Millions of medical images of various modalities are generally safeguarded through software-based encryption. DICOM format is a widely used medical image type. In this chapter, DICOM image encryption implemented on cyclone FPGA and ARM microcontroller platforms is discussed. The methodology includes logistic map, DNA coding, and LFSR towards a balanced confusion – diffusion processes for encrypting 8-bit depth 256 × 256 resolution of DICOM images. For FPGA realization of this algorithm, the concurrency feature has been utilized by simultaneous processing of 128 × 128 pixel blocks which yielded a throughput of 79.4375 Mbps. Noticeably, the ARM controller which replicated this approach through sequential embedded “C” code took 1248 bytes in flash code memory and Cyclone IV FPGA consumed 21,870 logic elements for implementing the proposed encryption scheme with 50 MHz operating clock.
A Framework for Image Encryption on Frequency Domain

In this chapter, the authors propose an improved image encryption algorithm based on digital watermarking. The algorithm combines discrete wavelet transform (DWT), discrete cosine transform (DCT), and singular value decomposition (SVD) together in a DWT-DCT-SVD framework to improve the robust watermarking technique. The secret image is embedded into both high-frequency and low-frequency sub-bands of the host image; this makes it difficult to be attacked in all the sub-bands. To reduce the size of a secret key, the authors use a logistic map to generate random images so as to replace the host images. They tested the algorithm by using five types of attacks and the results indicate that the proposed algorithm has higher robustness than traditional chaotic scrambling method and the DRPE method. It shows strong resilience against the five types of attacks as well as statistical attacks.

Cloud computing is an emergent computing paradigm; however, data security is a significant issue in recent time while outsourcing the data to the cloud preventing users to upload their data on cloud. The data forwarded to cloud can be protected using some cryptographic techniques based on identity, attributes, and prediction. But these algorithms lack their performance when a revoked user collude with cloud; therefore, it becomes essential to develop a secure data sharing framework with some enhanced cryptographic techniques. The proposed methodology presented a secure privacy preserving data sharing with encryption technique called dynamic unidirectional proxy re-encryption (PRE) with cipher text policy attribute-based encryption. The technique ensures the privacy, integrity, and security of the data while retrieving through the cloud. The framework is implemented in the cloud sim with java language. Experimental results proved that proposed frame work attains reasonable results compared to traditional methods.

In the existent system, data is encrypted and stored when passed to the cloud. During any operations on the data, it is decrypted and then the computation is done. This decrypted data is vulnerable and prone to be misused. After the computations are done, the data and the result are encrypted and stored back in the cloud. This creates an overhead to the system as well as increases time complexity. With this chapter, the authors aim to reduce the overhead of the systems to perform repeated encryptions and decryptions. This can be done by allowing the computations to happen directly on the encrypted text. The result obtained by performing computations on encrypted data will be the same as the ones done on the original plain text. This new security solution is fully fit for processing and retrieval of encrypted data, effectively leading to the broad applicable project, the security of data transmission, and the storage of data. The work is secured further with additional concepts like probabilistic and time stamp-based encryption processes.

In last few decades, a lot of work has been done in the field of cryptography; it is being considered one of the safe methods to protect data. It was first used to protect communication by individuals, armies, and organizational companies. With the help encryption method, anyone can protect their data from a third-party attack. Images are used in various areas like biometric authentication, medical science, military, etc., where they are being stored or transferred over the network and the safety of such images are very important. The newest movement in encryption is chaos-based, which is a better encryption technique than AES, DES, RSA, etc. It consists of different property such as sensitive independence on original situation, non-periodicity, non-convergence, etc. In recent times, many chaos-based image encryption algorithms have been proposed, but most of them are not sufficient to provide full protection to data. In this chapter, a survey of different chaos-based image encryption techniques is discussed.
On Securing Cloud Storage Using a Homomorphic Framework
Authors: Gupta Daya Sagar , Biswas G. P.
Published: January 2021

In this chapter, a cloud security mechanism is described in which the computation (addition) of messages securely stored on the cloud is possible. Any user encrypts the secret message using the receiver's public key and stores it. Later on, whenever the stored message is required by an authentic user, he retrieves the encrypted message and decrypts it by using his secret key. However, he can also request the cloud for an addition of encrypted messages. The cloud system only computes the requested addition and sends it to the authentic user; it cannot decrypt the stored encrypted messages on its own. This addition of encrypted messages should be the same as the encryption of the addition of original messages. In this chapter, the authors propose a homomorphic encryption technique in which the above-discussed scenario is possible. The cloud securely computes the addition of the encrypted messages which is ultimately the encryption of the addition of the original messages. The security of the proposed encryption technique depends on the hardness of elliptic curve hard problems.
