Noise Deduction in Novel Paddy Data Repository using Filtering Techniques
Authors: V Malathi , MP Gopinath
Published: December 2020

Classification of paddy crop diseases in prior knowledge is the current challenging task to evolve the economicgrowth of the country. In image processing techniques, the initial process is to eliminate the noise present in the dataset. Removing the noise leads to improvements in the quality of the image. Noise can be removed by applying filtering techniques. In this paper, a novel data repository created from different paddy areas in Vellore, which includes the following diseases, namely Bacteria Leaf Blight, Blast, Leaf Spot, Leaf Holder, Hispa and Healthy leaves. In the initial process, three kinds of noises, namely Salt and Pepper noise, Speckle noise, and Poisson noises, were removed using noise filtering techniques, namely Median and Wiener filter. Theinterpretation made over the median and Wiener filtering techniques concerning noises, the performance of the methods measured using metrics namely PSNR (peak to signal to noise ration), MSE (mean square error), Maxerr (Maximum squared error), L2rat (ratio of squared error). It is observed that the PSNR value of the hybrid approach is 18.42dB, which produces less error rate as compared with the traditional approach. Results suggest that the methods used in this paper are suitable for processing noise.
Scientific Applications in the Cloud: Resource Optimisation based on Metaheuristics
Authors: Mokhtari Anas , Azizi Mostafa , Gabli Mohammed
Published: December 2020

The advent of emerging technologies such as 5G and Internet of Things (IoT) will generate a colossal amount ofdata that should be processed by the cloud computing. Thereby, cloud resources optimisation represents significant benefits in different levels: cost reduction for the user, saving energy consumed by cloud data centres, etc. Cloud resource optimisation is a very complex task due to its NP-hard characteristic. In this case, use of metaheuristic approaches is more rational. But the quality of metaheuristic solutions changes by changing the problem. In this paper we have dealt with the problem of determining the configuration of resources in order to minimise the payment cost and the duration of the scientific applications execution. For that, we proposed a mathematical model and three metaheuristic approaches, namely the Genetic Algorithm (GA), hybridisation of the Genetic Algorithm with Local Search (GA-LS) and the Simulated Annealing (SA). The comparison between them showed that the simulated annealing finds more optimal solutions than those proposed by the genetic algorithm and the GA-LS hybridisation.
Forgery Protection of Academic Certificates through Integrity Preservation at Scale using Ethereum Smart Contract
Authors: Lone Auqib Hamid , Naaz Roohie
Published: December 2020

Academic credentials are precious assets as they form an evidence for one’s identity and eligibility. Fraud inissuance and verification of academic certificates have been a long-standing issue in academic community. Due to lack of antiforgery mechanisms there has been substantial increase in fraudulent certificates. The need of the hour is to have a transparent and reliable model for issuing and verifying academic certificates to eliminate fraud in the process. Decentralized, Auditable and Tamper-proof properties of Blockchain makes it possibly the best choice for issuing and verifying academic certificates. In this paper we propose a model, where regulatory body authorizes higher education Institutes (universities and colleges) for issuing academic certificates to students in a decentralized way. Anyone in the world can verify the authenticity of the certificate by triggering appropriate smart contract functions, thus eliminating any possibility of fraud in the process. In addition we used multi signature scheme where certificates are required to be signed by designated authority from Higher Education Institutes, thus allowing for multi-level checks on certificate contents before being successfully deployed on Blockchain. We have also provide Proof of Concept in Ethereum Blockchain and evaluated its performance in terms of cost, security and scalability.

Decentralized and Fault Tolerant Cloud Service Orchestration
Authors: Spataru Adrian
Published: December 2020

This paper proposes a decentralized framework for the orchestration of Cloud Services using heterogeneous resources residing in the homes of private individuals or small-scale clusters. The framework makes use of Ethereum Smart Contracts to provide a decentralized mechanism for discovering the different interfaces exposed by Cloud Components. The paper introduces a novel concept of Component Administration Networks, which are peer-to-peer networks that monitor and ensure the availability of the software components. The concept applied for the Orchestration process to ensure that the deployment of an Application continues in the presence of Orchestrator component failure. Checkpoints are used to address the continuity of the   Management components, in general, and of the Orchestrator, in particular. In our proposal, checkpoint metadata is stored in a Smart Contract to assess the execution time of a Service to reimburse the participants that ensure its execution.

Authors: Kyrou Foteini , Alexopoulos Nikolaos , Raptis Nikolaos
Published: December 2020

According to many studies teachers’ reception has been associated with the smooth operation of the school, the professional development of the teaching staff and the provision of optimal teaching work. Despite its significance and its attention from scholars, though, its implementation at schools has been facing challenges and hardships. The present study focuses on the role played by principals and teachers’ associations upon the reception and acclimatization of all newly appointed teachers in their schools. The findings indicate that the favorable disposition and actions of both principals and the teachers’ association in terms of receiving/acclimatizing any newly appointed teachers should be further enhanced.
Touring the carbon ruins: towards an ethics of speculative decarbonisation
Authors: Raven Paul Graham , Stripple Johannes
Published: December 2020

For many years, questions about the future have been marginalised within the social sciences: asking how we might live in a post-fossil society, or what are the key decisions and events that could take us there, has been seen as outside of the disciplinary scope. In this paper – which takes as its point of departure the ‘speculative turn’ that is increasingly inspiring a range of works, from foresight scenarios to design fiction – we insist on the need to invent methods and practices which provide speculative spaces that allow such questions to be articulated. We use our own speculative initiative, ‘The Museum of Carbon Ruins’, to foreground a series of ethical questions that accompany such speculative endeavours, but which have so far been neglected in contemporary discussions. Working within a critical utopian modality, Carbon Ruins does not foreclose ethical possibilities, but allows citizens to grapple with, evaluate, amend and critique the post-fossil futures that official policy is striving towards.
Two-wavelength phase-sensitive OTDR sensor using perfect periodic correlation codes for measurement range enhancement, noise reduction and fading compensation
Authors: Sagues Mikel , Piñeiro Enrique , Cerri Enis , Minardo Aldo , Eyal Avishay , Loayssa Alayn
Published: December 2020

We demonstrate a two-wavelength differential-phase-measuring OTDR sensor that uses perfect periodic correlation phase codes to enhance the measurement performance. The two-wavelength technique extends the measurement range of OTDR sensors by synthesizing a virtual longer-wavelength measurement from two simultaneous measurements of phase using different lasers. This increases the range free from phase unwrapping errors. However, we find that the application of this technique greatly increases the relative measurement noise. To compensate for this issue, we introduce the use of optical pulse compression using perfect periodic correlation phase codes to increase the measurement signal-to-noise ratio and also to facilitate the simultaneous compensation of Rayleigh and polarization fading. In addition, we apply a method to further reduce the relative noise that is added to the two-wavelength measurement by using the synthetic wavelength measurement to unwrap the differential phase measured with a single wavelength. All this is highlighted in a 1-km sensing link in which up to 20-cm spatial resolution and 12.6

Published: December 2020

Prospects for average power scaling of sub-MW output peak power picosecond fiber lasers by utilization of a Yb-doped tapered fiber at the final amplification stage were studied. In this paper, it was shown experimentally that a tapered fiber allows the achievement of an average power level of 150 W (limited by the available pump power) with a peak power of 0.74 MW for 22 ps pulses with no signs of transverse mode instability. Measurements of the mode content using the S2 technique showed a negligible level of high order modes (less than 0.3%) in the output radiation even for the maximum output power level. Our reliability tests predict no thermal issues during long-term operation (105 hours) of the developed tapered fiber laser up to kilowatt output average power levels.
Adaptive weighted Gerchberg-Saxton algorithm for generation of phase-only hologram with artifacts suppression
Authors: Wu Yang , Wang Jun , Chen Chun , Liu Chan-Juan , Jin Feng-Ming , Chen Ni
Published: December 2020

In the conventional weighted Gerchberg-Saxton (GS) algorithm, the feedback is used to accelerate the convergence. However, it will lead to the iteration divergence. To solve this issue, an adaptive weighted GS algorithm is proposed in this paper. By replacing the conventional feedback with our designed feedback, the convergence can be ensured in the proposed method. Compared with the traditional GS iteration method, the proposed method improves the peak signal-noise ratio of the reconstructed image with 4.8 dB on average. Moreover, an approximate quadratic phase is proposed to suppress the artifacts in optical reconstruction. Therefore, a high-quality image can be reconstructed without the artifacts in our designed Argument Reality device. Both numerical simulations and optical experiments have validated the effectiveness of the proposed method.

Published: December 2020

La responsabilidad social se fundamenta en la capacidad de elegir la propia conducta de manera consciente, deliberada, voluntaria, libre y en relación con otros. Cada generación tiene que responder del impacto de sus acciones y de la repercusión de estas sobre el desarrollo sostenible. Analizar y medir este tipo de constructos tiene importancia capital para la mejora de la Política Institucional en la Educación Superior como propone la UNESCO. El objetivo del presente estudio es ofrecer a la comunidad universitaria internacional un indicador sintético (índice) para la medida de la responsabilidad social del universitario que permita, con una escala de tan solo 6 u 8 ítems, evaluar con eficacia el grado de Responsabilidad Social del Estudiante Universitario (en adelante RSEU) en cualquier momento de su desarrollo académico. Un indicador con garantías de fiabilidad y validez suficientes y semejantes a los obtenidos en el instrumento inicial de 20 ítems. Se analiza la fiabilidad, homogeneidad y capacidad predictiva de estos índices sobre muestras de estudiantes universitarios de 2º y 4º curso de diversas facultades. Los resultados muestran el buen comportamiento de estos índices, así como su semejanza al instrumento completo.
Determination of the relationship between physician trust, medical mistrust, and self-confidence in the health services provided in Turkey
Authors: Şengül Halil , Bulut Arzu
Published: December 2020

Objectives: A sense of trust is of great importance for professional professions. Failure to establish trust, especially in an industry where information asymmetry is too high, such as the health sector, also poses important problems for both employees and society. In this study, we aimed to identify variables that affect the distrust of the health system and trust in the physician.

Material and Method: This study was carried out in the descriptive design. The study group consisted of 561 people living in different cities of Turkey and whose ages ranged from 18-70 years. “Personal data form”, “ Medical mistrust scale”, “Physician trust scale” and “generalized trust inventory infrastructure scale” were used as data collection tools prepared by the researcher. As a data collection method, the test method performed in a computer environment was used. One-way analysis of variance from parametric test statistics and Pearson correlation analysis test statistics were used to compare data. P<0.050 and p<0.001 were determined for the significance level.

Results: In our study, medical mistrust decreased as trust in the physician increased. As a person's level of self-trust increases, medical mistrust increases, and confidence in the physician also decrease. Dissatisfaction with the health service increases medical mistrust, while also reducing trust in the physician. Based on the preferred type of hospital, the level of medical mistrust of patients going to private hospitals is greater than the level of medical mistrust of patients going to public hospitals.

Conclusion: This study reveals the importance of trust in the health sector and the factors that affect it. More detailed studies on practices that will increase confidence in the importance of this issue and measures that will reduce distrust will make a great contribution to this issue.

Published: December 2020

The method for solving the matrix Diophantine equations over quadratic rings is developed. On the basic of the standard form of matrices over quadratic rings with respect to $(z,k)$-equivalence previously established by the authors, the matrix Diophantine equation is reduced to equivalent matrix equation of same type with triangle coefficients. Solving this matrix equation is reduced to solving a system of linear equations that contains linear Diophantine equations with two variables, their solution methods are well-known. The structure of solutions of matrix equations is also investigated. In particular, solutions with bounded Euclidean norms are established. It is shown that there exists a finite number of such solutions of matrix equations over Euclidean imaginary quadratic rings. An effective method of constructing of such solutions is suggested.

The frame power structures are widely applied when designing aircraft, in which composite rod elements are used to reduce the mass and size characteristics. To solve the problem of manufacturing rod elements from polymer composite materials, we developed a technology for the manufacture of carbon fiber pipes using an existing machine for winding carbon fiber, which provides the necessary strength and rigidity mainly in the longitudinal direction.When calculating the rod elements, all the loads that will affect the structure as well as the coefficient of thermal expansion should be taken into account. To achieve the required physical, mechanical, and thermophysical characteristics, the optimal scheme of reinforcement is the scheme with a quasi-longitudinal direction of the fibers. We developed the method of manufacturing based on the technology allowing us to obtain a reinforcement scheme with fiber orientation in the quasi-longitudinal direction with a reinforcement angle of about 1° by a combined method of layer-by-layer winding of carbon fiber. As a result of technological testing, we obtained samples of carbon fiber rod elements, which were used to confirm the calculated characteristics. To confirm the physico-mechanical and thermophysical characteristics, we determined the assessment of limit of strength and modulus of elasticity in bending, the limit of strength and modulus of elasticity in torsion, the limit of strength and modulus of elasticity in compression, and the coefficient of thermal expansion. The obtained characteristics of the dependences of the elasticity modulus of the pipe prototype material at the fibers’ orientation angle correlate with theoretical calculations.

We considered the problem of weight optimization of parameters of multi-layer composite shell produced by the method of continuous cross-winding under axisymmetric loading. Shell layers are placed symmetrically relative to the middle surface. The angles of the reinforcing material winding variable along the meridian and the thickness of layers are taken as the variation parameters. We propose an algorithm of the automated determination of the elastic constants of a composite material variable along the shell meridian anisotropy. The connection of the composite structure with the technological process of shell manufacturing by winding with a reinforcing tape under different angles to the axis of rotation is taken into account. The values of four elastic constants obtained as a result of experimental testing of witness specimens of the composite material along and orthogonal to the reinforcement are used as output. The equations of state of the moment theory of shells of the variable along the meridian orthotropy and wall thickness are obtained as a boundary value problem for a system of ordinary differential equations with variable coefficients. The use of the necessary optimality conditions in the form of the principle maximum of Pontryagin in the presence of arbitrary phrasal restraints made it possible to reduce the emerging multiparameter problem to a sequence of extreme problems of a significantly smaller dimension. This approach greatly simplifies taking into account the conditions of strength reliability, and technological and structural requirements of real design, and the process of finding an optimal project as a whole. The results of the optimization of a two-layer fiberglass shell of rotation are presented in the form of a change in the distribution of layers’ thickness and the glass fiber winding angle. Materials of research can be used to reduce the material consumption of structural elements in rocket and space technology and other branches.

Information on fault tectonics and the deep structure of the global trans-Eurasian belt of dislocations and planetary megafractures (Baltic-Iranian Super Lineament) is generalized based on the analysis of literary, geological and geophysical, cartographic, cosmographic materials, including the results of tectonic lineaments interpretation of cosmo-images of the Earth’s surface. The features of its distribution and segmentation are clarified. This Super Lineament is the trans-Eurasian structure of a planetary rank — an integral part of the regularly spatially oriented ancient reghmatic fault net of Eurasia, formed at the early stages of the formation of the rigid earth crust under the influence of global stresses associated with the factor of rotation of the Earth. The long-lived nature of the belt (the Upper Proterozoic — Cenozoic) and its quasi-stationary position throughout its formation history, as well as the absence of large-scale, hundreds of kilometers, of shear displacements along it and at intersections with transverse tectolineament belts of a similar rank indicate the low probability of the plate-tectonic convergence model of Afro-Arabia and Eurasia. The destruction model of the once united Afro-Eurasian continent in a potentially shear field of relatively low amplitude (on a planetary scale) dislocations is preferable. The geodynamic mode of formation and development of the belt as a whole cannot be described by any one type — riftogenic, or collisional ones. Regional and supra-regional zones of extension (riftogenic zones) and compression (collision) alternate in it periodically. It shows the global nature of the belt, the union of different geodynamic regimes in it, as well as the wave character and hierarchy of the tectonic process.
Is there any connection between solar activity and earthquakes?
Authors:   Main Astronomical Observatory, National Academy of Sciences of Ukraine, Kyiv, Ukraine, Vasylieva I.E.
Published: December 2020

A possible relationship between solar activity and the seismic activity of the Earth is considered. We analyzed the frequency of occurrence of earthquakes of various magnitudes with the Fourier transform: for M ≥ 7 over the period 1900—2019 and for 2.5 ≤ M ≤ 7 over the period 1973–2019. The average annual, monthly, and daily values of the solar-terrestrial variables, the number of earthquakes with intensities that fall within the specified boundaries are calculated. The epoch overlapping method was used to analyze the possible relationship between the Wolf numbers and the number of earthquakes at the corresponding moment in the cycle. 4 periods of each solar cycle were identified: the phase of ascending, maximum, descending, and minimum. Earthquakes over the entire globe and in the regions of extension and compression of the earth's crust were analyzed for each phase. No statistically significant dependencies between solar-terrestrial variables and earthquake initiation were found for all time intervals and all selected earthquake magnitudes. An interesting fact was established concerning the change in the number of earthquakes at different periods of the day. The number of earthquakes in the nighttime appreciably increases (by ~ 10 %) compared to the daytime. A slight increase in the number of earthquakes after local noon was also detected. We could not confirm the existence of a direct connection between solar activity and the seismic activity of the Earth, but we cannot also claim that such a connection does not exist.

Aim. To study the rehabilitation effect of the combination of aerobic and breathing exercise during stroke recovery in elderly women.

Material and methods. The study was carried out on the basis of a geriatric home for 3 months. It involved 24 women aged 60-70 years at a long-term period after an ischemic stroke. The physical rehabilitation program for patients with mild neurological consequences consisted of two blocks: respiratory and aerobic exercise. Hemodynamic parameters, respiratory function, and exercise tolerance was assessed.

Results. Preliminary examination of women revealed low respiratory reserves. The most significant changes were recorded in relation to bronchial patency. The hypokinetic circulation type with high blood pressure was determined, while the mean dynamic pressure significantly exceeded 100 mm Hg. The implementation of the physical rehabilitation program provided a stable positive effect with an increase in the functional respiratory reserves and exercise tolerance, the optimization of cardiovascular homeostasis. Parameters of bronchial patency increased significantly in comparison to the initial level (p<0,01). Aerobic exercise provided a decrease in the heart rate (p<0,05). The resulting effect of rehabilitation was a decrease in the main hemodynamic parameters, a change in the circulation type with an increase in the cardiac index to 2,10±0,1 l/m2, (p<0,01). In the control group, the rehabilitation effect was less pronounced and mostly associated with a decrease in blood pressure.

Conclusion. A long-term stay of patients after ischemic stroke in a geriatric home opens up wide opportunities for effective recovery using rehabilitation programs.
