Reduced Order Model of A Microgrid System for A University Community in Nigeria
Authors: Ogbikaya Stephen , Iqbal M
Published: September 2022

This paper presents a reduced order model of a microgrid system for a university community in Nigeria. The designed microgrid system is simulated in MATLAB/Simulink environment to determine the system dynamics. The obtained dynamic system is then reduced to a single block subsystem with multiple inputs and a single output using system linearization. The microgrid model is then linearized with the aid of linearization tool in MATLAB/Simulink using linearized perturbation method. The transfer function of the multiple inputs with respect to the single output of the microgrid system is determined in MATLAB environment. The transfer functions obtained for both inputs are then incorporated to the subsystem to linearize the entire system. The obtained linearized system is reduced with the aid of model reducer using the balanced truncation method in Simulink. The achieved results indicate that the system response of the obtained linearized model is linear compared to the step response of the nonlinear microgrid model of the campus. The results also reveal that the obtained reduced order model - compared to the nonlinear microgrid model - has lesser states with more than 4 times faster simulation response time.
Techno-Economic Feasibility Analysis of On-Grid Battery Energy Storage System: Almanara PV Power Plant Case Study
Authors: Arfoa Aouda , Almaita Eyad , Alshkoor Saleh , Shloul Maan
Published: September 2022

Battery energy storage systems (BESSs) are considered one of the most developed energy storage system (ESS) technologies because they have different benefits for distribution networks like smoothening the output fluctuations, improving the power quality, peak load shifting, voltage support and delaying the distribution network upgrade. This work involves integrating a BESS into a 33 KV distribution network in Jordan. CYME software is used to assess the impact of BESS at Almanara PV power plant on the 33 KV medium voltage network. The voltage level, power losses, power factor (PF) and voltage step are chosen as performance indicators. For each of these indices, comparisons between the grid performance with and without the BESS are carried out. In addition, the payback period of the BESS is calculated. The obtained results reveal that BESS not only improves the voltage level – with an overall improvement of about 3.03% at both feeders – but also reduces the losses, with an overall reduction in losses of 4.68% at both feeders. BESS is found to decrease the PF with an average of 0.83 at both feeders, while the voltage step doesn’t exceed the limits set by the International Electro-technical Commission (IEC). Additionally, the performed economic analysis unveils that the payback period is about 10.98 years.
The Proportion and Type of Carbohydrates in the Diets of Children in Early Adolescence
Authors: Pasalic Arzija , Segalo Sabina , Brankovic Suada , Mahmutovic Jasmina , Konjo Hadzan
Published: September 2022

Background: Carbohydrates are mainly substrates for energy metabolism and can affect satiety, blood glucose levels, insulin secretion, and fat metabolism. Their amount and type in the diet affect metabolic responses. High-carbohydrate diets, particularly high sugar consumption, are considered particularly harmful because of their specific characteristics related to postprandial metabolism, effects on hunger and satiety, and thus on caloric intake and energy balance. The European Food Safety Authority has suggested that the reference intake for carbohydrates should be between 45 and 60% of total energy requirements and less than 10% should be added sugars, especially for children. Objective: Investigate the proportion and type of carbohydrates in the diets of children in early adolescence in two territorially distinct areas, the continental and the Mediterranean. Methods: The study was conducted as part of a longitudinal cohort study. The survey was conducted in elementary schools in two regions: continental and Mediterranean. The School Physical Activity and Nutrition Survey was used for research purposes. Descriptive and inferential statistical tests were applied for data analysis. Results: A total of 1,411 respondents of both sexes aged 12-15 years, 729 boys and 678 girls, participated in the study. The intake of carbohydrates in the total sample is represented in the daily intake of 59%. The proportion of natural sugar in the diet of boys is statistically significantly higher in the continental compared to the Mediterranean region at the age of 12-13 years (p = 0.002), 13-14 years (p = 0.049), and 14-15 years (p = 0.002). Added sugars in total carbohydrate intake are statistically significantly higher in girls in the Mediterranean region compared to the continental region at ages 12-13 years (p = 0.048), 13-14 years (p = 0.001), and 14-15 years (p = 0.001). Conclusion: The high intake of added sugars in children in the Mediterranean region is of concern, although the intake in the continental area is well above current recommendations. Therefore, one of the public health goals is to promote proper nutrition as well as the availability of healthy foods in schools, especially during early adolescence when proper eating habits are adopted.
A Legal Exploration of the European Union’s Carbon Border Adjustment Mechanism
Authors: Leal-Arcas Rafael , Faktaufon Manuliza , Kyprianou Anna
Published: September 2022

In December 2019, the European Commission released a mechanism to fight climate change, namely the European Green Deal. This policy was put in place to materialize the goals of the Paris Agreement on Climate Change of 2015, that is, to combat the issue of climate change along the lines of sustainable development and fight poverty. In the context of the European Green Deal, one of the key instruments envisaged to achieve the ambitious plans of the European Union (EU) is the so-called Carbon Border Adjustment Mechanism (CBAM), which is the focus of this article and has been described as an ‘extraterritorial outreach’ for attempting to regulate matters outside the EU borders. This article seeks to answer is whether the CBAM is justified in line with the need to protect the environment and address climate change as well as increasing global economic welfare and reducing poverty. This article provides an overview of CBAM, analyses the rationale behind CBAM as well as the various misgivings from third parties. It contextualizes CBAM in the context of free trade and examines whether CBAM is consistent with multilateral trade rules. It then provides the design of a CBAM based on the principles of international trade and sustainable development. The article concludes that, overall, the analysis of CBAMs, particularly regarding the fervency of the EU to make its CBAM compatible with both trade rules and climate change objectives, demonstrates states’ growing interest in protecting the planet, while preserving economic values; it also indicates the importance of trade in managing those interests.

EU Accession Conditionality and Compliance with the Energy Community Treaty: A Missing Link
Authors: Lelli Maria
Published: September 2022

EU accession conditionality is expected to be an incentive for third countries to apply EU energy rules. However, looking at the latest Energy Community (EnC) Implementation Report (2021), Ukraine, then a non-candidate country, performed better than the candidate country of Serbia in liberalizing its energy sector. Adopting the EU external governance approach, this article investigates whether this result depends on the EU’s bargaining power or, rather, on the domestic cost-benefit calculation of implementing the EnC acquis. While applying this legislation proves to be quite costly for both Serbia and Ukraine, the EU’s bargaining power turns out to have opposite effects in the two cases. This has increased in Ukraine as a result of the deterioration of relations between Moscow and Kiev, thus leading to an increasingly implementation of the EnC acquis. Conversely, the EU’s bargaining power has decreased in Serbia due to Russia’s significant presence in the country’s energy sector, which is a major obstacle to the implementation of the EnC legislation. A significant level of EU bargaining power has therefore the potential to reverse the impact of domestic factors, leading to a reconsideration of the role that international energy dynamics play in accession conditionality. Finally, conclusions are drawn on how the EnC can benefit from this finding and improve its effectiveness.

Quo Vadis? Export Credit Regulation After Corona: State Aid, WTO Export Subsidies Laws and the Arrangement
Authors: Jennekens Bob
Published: September 2022

Officially supported export credits matter greatly for private contracts: they provide the possibility of large export transactions and contracts which would otherwise not take place. It is therefore important to know how these instruments are regulated on an international level. The international regulation for public European export finance has three levels: rules set by the WTO to curb export subsidies, the Arrangement on Officially Supported Export Credits (which is a gentlemen’s agreement) and the EU state aid framework. Whilst the WTO framework has an official carve-out for the Arrangement, the EU state aid regime does not. Post-Covid, this article looks at the way to proceed with regulating official export credits, and how the different levels of regulation should be applied (and when), concluding that the Arrangement should be the core text of international regulation on export credits.
Missing (in) Action: Where Are the Australian Data Breach Class Actions?
Authors: Dawson Sophie , Croft Emma
Published: September 2022

Data breach class actions have been a feature of the privacy landscape in the US and UK since as early as 2002. While Australia has experienced a surge in regulatory actions brought in respect of data breaches, we have yet to see an uptick in consumer actions in Australia. An action was brought in 2018, however it settled prior to receiving judicial consideration.

This article provides some examples of the difficulties of bringing such actions in Australia, both at a substantive and procedural law level.

We also highlight some proposed upcoming legislative changes which may have an impact in this space, including the proposed introduction of a tort of privacy and direct right of action in respect of interferences with privacy under the Privacy Act 1988 (Cth) (Privacy Act).

Honte du corps ou gloire du corps ? La honte de Gn 3 comme atout pour l homme d après la Théologie du corps de saint Jean-Paul II
Authors: Leuridan Martine
Published: September 2022

Et si c’était une bonne chose de pouvoir ressentir de la honte au sujet de son corps ? Formulée ainsi, la question ressemble à une provocation malvenue. Il se pourrait toutefois que nous soit offert à travers cette expérience déplaisante un véritable atout. La Théologie du corps de saint Jean-Paul II conduit de fait à saisir que la honte qui survient pour Adam et Ève au troisième chapitre de la Genèse est susceptible de servir notre édification et notre épanouissement authentiques – rien moins que cela. À partir de là, au lieu de chercher à s’en débarrasser au plus vite et à mauvais escient, il conviendrait plutôt de l’accueillir pour ce qu’elle est, et d’apprendre à lui permettre de jouer son rôle pour notre bien véritable !

Di setiap set otak terdapat sebuah pusat yang banyak cabangnya dan setiap cabang mempunyai  banyak koneksi. Setiap set otak dibuat lebih kuat dan canggih daripada kebanyakan peralatan komputer di dunia . Setiap set saling berhubungan dengan ratusan set yang lain dan mereka saling bertukar informasi. Dari triliunan sel otak tersebut, ada sepersepuluhnya terdiri neuron atau sel saraf aktif yang bisa terjadi  hingga 20.000 koneksi yang berbeda dengan sel-sel lain. Otak manusia terdapat  empat bagian dan pada tiga tingkatan yang berbeda dari atas batang otak dan yang keempat terselip di bagian belakang. Otak manusia juga memiliki dua sisi yang mana setiap sisinya mempunyai fungsi yang berbeda dan memproses informasi dengan cara yang berbeda pula. Konsep tiga otak dalam satu kepala ( otak triune) menjelaskan tentang cara kerja otak dan hubungannya dengan proses pembelajaran. Proses pembelajaran yang memaksimalkan fungsi otak berarti bukan  hanya memberdayakan satu belahannya saja, tetapi mengupayakan pemaksimalan kedua belahannya. Sehingga bisa menghasilkan siswa yang bukan hanya mampu berfikir berurutan dan terstruktur tetapi  mampu berfikir secara divergen, global dan kreatif. Secara neurosains, ingatan adalah proses kerja otak yang disertai penyimpanan memori di dalam sistem sinapsis antara neuron. Daya ingat berkaitan langsung dengan proses belajar karena memungkinkan seseorang untuk menyimpan dan mengambil informasi yang telah dipelajari. “Dengan demikian, daya ingat atau memori tergantung pada proses belajar.

Evaluation of organizational ethics in terms of businesses: The case of Virgin Atlantic Airways and British Airways
Authors: Yılmaz Rabia
Published: September 2022

The concept of ethics, which examines the values relating to good and evil and right and wrong, has always occurred and been discussed at any time of human life from past to present. Especially after the industrial revolution, which is deemed as the beginning of globalization and industrialization, ethics has started to be a benefit for businesses with the establishment of more professional businesses. In this sense, top-level businesses of today that act within the scope of organizational ethics adopt universal moral values. In this study, a case study is carried out within the framework of a different view, using the literature review method on the dirty tricks campaign of Virgin Atlantic Airways and British Airways in relation to the universal ethical values that support organizational ethics, processes in ethical decision making and the application of organizational ethics. As a result of the case study, it was concluded that it was true to bring organizational ethical principles and rules to the forefront and act ethically by Virgin Atlantic Airways. It is concluded that British Airways harms its organizational image and completely ignores organizational ethics by acting contrary to it and not applying organizational ethical values and principles. In this context, this study aimed to emphasize the ongoing importance of organizational ethics in every stage of business life cycle and to determine the ways of the benefits obtained in businesses in which organizational ethics are applied. This study also aimed to provide theoretical benefits to businesses on organizational ethics.
DEVELOPMENT, PURIFICATION, AND CHARACTERIZATION OF IGY ANTIBODIES AGAINST VITELLOGENIN OF THE "VIEJA COLORADA” FISH (CICHLASOMA FESTAE), A SPECIES NATIVE TO THE GUAYAS RIVER, ECUADOR

Published: September 2022

Vitellogenin (Vtg) is a specific phospho glycoprotein used as an environmental and steroidogenesis biomarker in fish. The present study shows the techniques to isolated IgY anti vitellogenin (Vtg) in Cichlasoma festae fish. Vtg was purified from adult males previously treated with estradiol and isolated from blood plasma using ion-exchange chromatography. Subsequently, Lohmann Brown hens were immunized at different doses, including three antigen booster doses. At day 45 post-immunization, posture eggs were collected, and successfully optimized the extraction of anti-Vtg -IgY antibody. The purified antibodies were validated with SDS-PAGE, detecting heavy and light chains of 70 kDa and 30 kDa, respectively. Further, we developed ELISA to estimate the Vtg specificity. Commercial anti-Vtg antibodies of Dorada (Sparus aurata) were used as a control, and immunoglobulins Y were validated for native species by Western Blot. The IgY anti-Vtg obtained by local conditions can be successfully used for programs in environmental monitoring and reproduction control in native aquatic species in Ecuador.
Parsimonious Bivariate T-distribution Type Symmetry Models for Square Contingency Tables
Authors: Iki Kiyotaka , Tomizawa Sadao
Published: September 2022

For square contingency tables with ordered categories, Iki, Ishihara and Tomizawa (2013) considered the t-distribution type symmetry model and Iki, Okada and Tomizawa (2018) extended this model. These models are appropriate for a square contingency table if it is reasonable to assume an underlying bivariate t-distribution having any degrees of freedom. This study proposes three kinds of parsimonious models for these models. Additionally, this paper provides the decompositions of the parsimonious symmetry model using the proposed model. Some simulation studies based on bivariate t-distribution show the performances of the proposed models.
siglo XVIII según Menéndez Pelayo
Authors: Álvarez Barrientos Joaquín
Published: September 2022

El objetivo principal de este artículo es ayudar a comprender el siglo XVIII desde la perspectiva de Menéndez Pelayo. Para ello, se tienen en cuenta diferentes puntos: El siglo de la Ilustración en la ‘Historia de los heterodoxos’, Ideología y literatura (La Historia de las ideas estéticas en España) y Las «Advertencias preliminares» de 1910 a los Heterodoxos. Se profundiza en el pensamiento de Menéndez Pelayo acerca de lo que supuso este periodo desde un punto de vista ideológico, político, religioso e incluso sociológico, sin olvidar la ciencia y la cultura, y se ponderan los aspectos positivos y negativos. Aunque en un primer momento el siglo XVIII fue percibido por Menéndez Pelayo como una etapa de pérdida de valores espirituales, hay una evolución en el pensamiento del autor cántabro, que acaba por aceptar su importancia. Así, la investigación permite concluir que el siglo XVIII fue un siglo clave tanto para Pelayo como para nosotros.
Padre Apolinar y Nazarín, dos modelos de religiosidad en la novela decimonónica española
Authors: Madariaga de la Campa Benito
Published: September 2022

El objetivo principal de este artículo es llevar a cabo una rigurosa descripción y análisis de las figuras del Padre Apolinar y de Nazarín. Estos dos modelos de religiosidad tienen algunas similitudes, pero sobre todo muchas diferencias, reflejadas y contrastadas en el texto. Pereda incluyó al Padre Apolinar en una de sus obras (Sotileza) y lo retrató como alguien humilde, que atiende espiritualmente a la población pescadora y enseña. Se corresponde con la imagen de cura identificado con la vida del pueblo: se preocupaba por los necesitados y compartía su pobreza. Galdós, por el contrario, se inventó a Nazarín, considerado un santo y un simple a partes iguales. También se le califica como místico, pordiosero, mendigo o loco. Este personaje se convierte en un símbolo dentro de la historia y es comparado con Jesucristo. Galdós recibió críticas que señalaban una clara influencia rusa, pero el escritor lo desmintió; su inspiración era únicamente española.

Authors: Estébanez Calderón Demetrio
Published: September 2022

El artículo se centra en la Revolución de 1868 como referencia en la creación literaria de Pereda. La revolución de 1868 y el Sexenio Democrático constituyen un hito fundamental en la modernización de España desde el punto de vista político, económico y cultural en los ámbitos de la educación, la prensa y la creación literaria. Pereda somete a crítica y degradación caricaturesca los acontecimientos, instituciones y personajes políticos más relevantes del Régimen, así como determinadas disposiciones legales del Gobierno; critica la corrupción política y el caciquismo. Expone, del mismo modo, su pensamiento e ideología tradicionalista, antiliberal y neocatólica.
Regionalismo y resquemores: Pereda y la Fiesta Montañesa
Authors: García Castañeda Salvador
Published: September 2022

El siguiente artículo se centra en la Fiesta Montañesa, celebrada el 12 de agosto de 1900, y presidida por Pereda, Menéndez Pelayo y Jesús de Monasterio; y las opiniones que surgieron alrededor de esta. La fiesta pretendía promover el regionalismo y buscar raíces que afirmen y definan ese concepto tan difuso de lo montañés. La Fiesta Montañesa dio lugar a la concienciación de un amplio sector de la población. No obstante, también dio lugar a numerosas cartas con encontradas opiniones; algunos de sus autores firmaron con sus nombres y otros lo hicieron con seudónimos. Uno de los seudónimos empleados era Resquemín, personaje de El sabor de la Tierruca.

La educación del año 2020 en Venezuela, con el inicio de la COVID-19, estuvo signada por tres momentos en los que la modalidad varió. Hubo presencialidad hasta el 13 de marzo, educación a distancia asíncrona del 16 de marzo al 23 de julio y educación virtual síncrona, del 7 de septiembre al 18 de diciembre. Los actores educativos, tuvieron que adaptarse a estos cambios. El objetivo de este estudio se centró en reconocer el equilibrio entre las variables de ajuste organización-persona y adaptación persona-organización como claves para el sostenimiento de la satisfacción laboral en el personal administrativo y docente del contexto educativo venezolano. La metodología parte del enfoque cuantitativo, en un diseño de campo de nivel descriptivo con la aplicación de un instrumento previamente validado y cuyos resultados se sometieron al análisis estadístico. Los hallazgos muestran un incremento significativo entre la primera y segunda medición de la variable: ajuste organización-persona y una disminución en los constructos de: adaptación persona-organización y satisfacción del empleado, a partir de lo que se corroboró que la satisfacción del personal está más relacionada con la adaptación persona-organización que con el ajuste organización-persona. Se recomendaron cuatro estrategias para incrementar dicha satisfacción.

Published: September 2022

The project demonstrates the use of modern technologies for preservation and presentation of the cultural and historical heritage. The idea is a database of cultural and historical heritage sites to be created applying threedimensional laser scanning technology and a combination of geodetic and photogrammetric methods and shooting techniques.
For the purposes of carrying out this project, we have focused on some heritage sites in the central part of Sofia. We decided to include these particular buildings because of the fact that there is hardly another city in the world where within a radius of 400 m are located four temples of different religions - Jewish, Muslim, Orthodox and Catholic.
In the recent years, preservation of cultural heritage has been increasingly linked to objectives of sustainable development. Today, it has become clear that cultural heritage is also an economic resource that should be used for further economic development (through compulsory preservation of its authentic cultural values). There has been a more active public debate on the role of cultural heritage, regarding the following topics: improving the quality of life through development of cultural tourism, leading to an increase of the employment rate, constantly improving the business climate, etc. Cultural heritage preservation is becoming one of the priority objectives of the urban development policy.
The focus has been shifted to new ways of preservation, mainly combinations of sophisticated technological solutions and their application for the purposes of preservation and dissemination of the cultural heritage.

Hagiotheca Preslavica (Reconstruction of the Preslav hagiographical collections: Publication and Research of the Stanislav’s menaion chetii 1 manuscript) is a project, developed by a team of young Bulgarian medievalists 2 . Its principal task is the preparation and publication (both digital and traditional) and research of the Stanislav’s menaio ncheti (better known as 1039 manuscript
from the “St . St. Cyril and Methodius“ National Library. Although it is a 14 th
century copy, the manuscript preserves a number of authentic texts that allow us to reconstruct faithfully the initial contents of menaiachetii, compiled and translated during the Golden Age of the medieval Bulgarian literature and culture. The realization of the project will be completed by webbased, easily navigable digitalization of the Stanislav’s menaion cheti, creation of a matrix for the description of the texts, enabling searching and grouping. This will provide the conditions necessary for the work of the team as well as of the wider academic community.

Digital Image Denoising by Adaptive Median Filtering and Wavelet Transform
Authors: Sharlandjiev Peter , Nazarova Dimana , Berberova Nataliya
Published: September 2022

Digital image processing is an important area of preservation and representation of cultural and historical objects. Part of it is the task of cleaning images corrupted by noise. Many different methods and approaches have been successfully implemented, but still filtering and denoising techniques are developing and improving intensively. Herein, we report numeric simulations of 2D image filtering. Effects of impulse noise are very efficiently reduced by adaptive median filtering. The situation of additive noise, which itself depends on the intensity of the original image, is more complicated. However, we demonstrate that in this case the use of wavelet transforms in the denoising procedure is very productive and promising.

An Android Application for Computing Selected Areas on Images in Restauration of Mosaics and Frescos
Authors: Stošić Miloš , Stanković Radomir
Published: September 2022

This paper describes an Android application which allows comput ation of the physical area of a se lected region of an image. The System is inten ded for helping archaeologists on fields and archaeological sites. The basic pri nciple of the operations is that the user of the application takes a picture of some shape, object or landscape. First, the user has to select the unit of measurement that is always present on the screen, by using already implemented tools. Then you select an appropriate mosaic that you want to be calculated, and the calc ulated area is presented on the screen. The major advantage of the system is to resolve the problem of computating the area of the damaged part of the mosaics
on field.

Kinship Terminology in the Corpus of Bulgarian and Ukrainian Parallel Texts
Authors: Derzhanski Ivan , Siruk Olena
Published: September 2022

In this study we examine the occurrences and correspondences of terms for blood kinship in a Bulgarian – Ukrainian parallel corpus of fiction. All instances of the terms selected for study, matching and nonmatching, were located and counted, and the frequencies compared. Several interesting asymmetries are found, some due to differences in the structure of the kinship systems, which in turn have roots in culture and history, others reflecting diverse features of language and the practice of literary translation.

Authors: Bozov Stefan , Zaharieva-Stoyanova Elena
Published: September 2022

This paper considers problems related to the development of knitting software for manual knitting. The support of error handling in knitting software is important for the users. The paper introduces an XML-based approach which allows recreating limitations due to the knitting technology. Each of them represents a Rule which contains certain conditions. One condition describes, allows or doesn’t allow combinations of stitches. The XML-based limitation scheme is developed for building on CAD systems for manual knitting. The users of such software applications could be: people who are interested in knitting as a hobby; editors of knitting hobby magazines; ethnographers who deal with the area of old traditional costumes and manual knitting.

Main Architectures Used in ETL as a Tool, Necessary for the Integration of Data in Large Volumes - a Task in the Field of Digital Preservation of Cultural Heritage
Authors: Angelov Kamen
Published: September 2022

The digital recording of Cultural Heritage (CH) and its metadata relates to the concept for data warehousing systems and their lifecycle. It uses models and development tools of ETL packages. The tasks used to extract metadata from raw digitized CH data often include hard computing problems, including NP-complete problems.
This paper describes the current state of digital preservation of Cultural Heritage with an accent on data integration and performance optimization of processes. We show our vision for further solutions for automated optimization of resource utilization in ETL jobs cutting development cost.
In parallel, we describe our experiment that uses quantum computation (in simulation mode) to solve hard combinatorial problems as multiple query optimization.
Optimization of Natural Dyes' Non-contact Characterization and Interdisciplinary Application Using Ensemble Classifiers and Genetic Algorithms
Authors: Stoyanova Magdelena , Luchev Detelin , Dessislava.Paneva-Marinova
Published: September 2022

The reported evaluation of the problematic encountered by noncontact characterization of natural dyestuffs demonstrates that practically no one analytical method alone – destructive, less, or non – can warrant absolute reliability of the results. The main obstacles are due, in general, to our limited knowledge on reactivity of natural compounds, their sources, methods of proceeding and application; to the complexing role of the ambient/medium on the photo reactions, as well as to the actual possibilities of analytical techniques; to the lack of commonly accepted standards amongst different scientific traditions, etc. For to overwhelm these drawbacks and optimize accuracy of NDs characterization, we propose the integration of chemio-physical with computational assessment. The proposed approach consists in calculation the probability of a hypothesis comparing new results with already stored interdisciplinary data using the high performance ensemble techniques Random Forest and Random
Subspace based on the genetic approach termed EV-Ensemble approach. Its role is to render more accurate the analytical results, to avoid sampling and simplify the identification analysis, to facilitate interdisciplinary applications of
NDs in high technologies, and to share generated experience between the research community.
