Multi-attribute Seismic application for Modeling Static Reservoir In “Athran” Field South Sumatera Basin
Authors: Agustine Diah Wully
Published: September 2020

“Athran” field is an active field for hydrocarbon exploration with trending northeast-southwest and focus on the reservoir zone is the Talang Akar Formation with A-C layer intervals. The method used in this research is electrofacies, delta deposition system, formation evaluation, static reservoir modeling, and multi-attribute linear regression. The distribution of reservoir modeling is done by using the stochastic variogram method to make modeling lithofacies and depositional facies. Identification of lithofacies in the study area obtained two units, namely sandstone and shale facies. The depositional facies analysis was carried out using the electrofacies approach, showing that the research target was in a transitional environment with a delta deposition system, namely the distributary channel, delta front and prodelta. The deposition process. Sandstones and shales affect the distribution of porosity which functions as a reservoir property. The data integration of the distribution of lithofacies, gamma ray and porosity was carried out using the multi-attribute linear regression method to predict data both vertically and horizontally. The results of this study are used to help determine the distribution direction and direction of sediment deposition as a good reservoir zone for exploration activities.
Is This Is Not an Atlas an Atlas? On the Pitfalls of Editing a Global Collection of Counter-Cartographies
Authors: Halder Severin , Michel Boris , Schweizer Paul
Published: September 2020

As part of kollektiv orangotango+, we co-edited an international collection of activist, academic, and artistic “counter- mappings.” Because counter-mapping is historically closely connected with, and indebted to, anti-colonial struggles and decolonial politics, we hoped to locate our work within the wider debates about decolonial cartography and the decolonizing of the map. At the same time, preparing, producing, and distributing this publication posed a number of questions and problems. We use this short article as an opportunity to reflect on the editing, publication, and dissemination of This Is Not an Atlas, as well as to trace possible ways beyond the book for Not-an-Atlas as an ongoing project.
Extension to quadratic anisotropic scattering in one-speed neutron transport equation for critical thickness calculations / Berücksichtigung der quadratischen anisotropen Streuung bei der Lösung der 1-Geschwindigkeites-Neutronentransportgleichung zur kritischen Dickenberechnung
Authors: Koklu H. , Ozer O.
Published: September 2020

The effect for different types of scattering on the critical half thickness in slab geometry for one speed neutron transport equation is studied for isotropic, linearly anisotropic and quadratic anisotropic scatterings. An extensive numerical survey is carried out for the critical thickness in order to provide the effect of the different scattering types. The numerical results are obtained by PN, TN and UN methods. The PN method is the Legendre polynomial solution that is accepted as the exact result for the neutron transport theory calculations and the UN and TN methods are the types of Chebyshev polynomials. Critical thickness values are calculated by using Mark boundary condition. Results are compared with the literature

Authors: Uvakin Maxim , Makhin Igor , Nikolaev Alexandr , Sotskov Evgeny
Published: September 2020

This paper presents a test safety assessment calculation technique for operating high power VVER units in daily maneuvering regimes. The test of maneuvering operation is an actual problem of VVER reactors exploitation. Corresponding tests are classified as nuclear hazardous procedures which are accompanied by power variations, regulators actions and continuous space power field fluctuations. As a result a lot of possible reactor plant conditions can occur. This fact is taken into account during the safety assessment of such tests. The proposed technique is based on a conservative approach. The paper contains a step-by-step structure of the method, the description of the calculation procedures and the applied models for each step. Initial conditions for selected RIA accidents are given and justified. Conclusions important for the practice are supported by method application results analysis for assigned task. All calculations are conducted using the KORSAR/GP programming code with 3D-neutrion kinetic model.
Investigation of the effects of different composite materials on neutron contamination caused by medical LINAC / Untersuchung der Auswirkungen verschiedener Verbundmaterialien auf die Neutronenkontamination durch medizinische LINAC

Published: September 2020

In a medical linear accelerator, the primary and secondary collimators are generally made of high atomic weight metals. The energy of the x-rays generated by accelerated electrons exceeds the bonding energies of high atomic number materials such as tungsten, and lead in the structure of the components in the accelerator head, it causes the production of neutron from the nucleus. Consequently, the resulting photo-neutrons can easily be scattered and spread into the treatment room. Thus, an additional neutron dose cannot be ignored in the tumor volume of the patient and in areas outside this volume. The contribution of the primary and secondary collimators to the neutron contamination is found to be approximately 52% and 30%, respectively. In this paper, the effects of using different composite materials such as Boron, Cadmium, and Polyethylene in secondary collimators on neutron contamination have been investigated by using Fluka Monte Carlo and TALYS 1.9 codes

Authors: Shokr A. M.
Published: September 2020

This paper discusses potential safety challenges to continued operation of nuclear installations during pandemic lockdown. While operating organizations are still learning the lessons, experience with the Corona virus outbreak has shown that continuity of operation requires an effective business continuity plan ensuring that adequate safety measures, with due account for all potential challenge, are maintained as the highest priority. These challenges may affect various organizational and technical areas related to operational safety, such as leadership and management for safety, staffing arrangements, training and qualification of personnel, maintenance, testing and inspection, supply chain, and operational radiation protection and radioactive waste management. The pandemic could also affect the effectiveness of regulatory oversight and emergency preparedness. Analysis of these challenges and suggested measures to address them, along with elements to be covered by the business continuity plan are presented and discussed in this paper.
FACTORS INFLUENCING THE FOREIGN RELATIONS OF THE ISLAMIC REPUBLIC OF IRAN AND THE REPUBLIC OF AZERBAIJAN
Authors: ALİSHAHİ Abdolreza , FOROUZAN Younes
Published: September 2020

After the collapse of the Soviet Union in the 1990s and the independence of the countries under its control, The Islamic Republic of Iran, on its northern borders, became neighbors with new countries. Azerbaijan is one of those countries that is located in the Caucasus region and declared independence on August 30, 1991, and the Islamic Republic of Iran recognized that country in the same year (1991) and established its relations with this country. During the years of the establishment of relations between the two countries. In spite of the religious and cultural commonalities, as well as the numerous opportunities and economic and security factors that could have exacerbated the interactions between the two sides, these relationships have been practically at a low level, and these joint factors not only did not increase interactions, but in some cases also led to conflicts and tensions between the two countries. According to this background, the question of this research is what factors influenced relations between the Islamic Republic of Iran and the Republic of Azerbaijan? The hypothesis of this paper is that the factors affecting the relations between the two countries, have been influenced by the negative attitudes of both countries towards each other and the involvement of transnational nations. Therefore, this research has sought to answer this question by adopting a constructive approach and using a descriptive-analytical method. The data collection in this research is carried out with library and internet tools.
The Missing Policing
Authors: Ben-Ishai Ofra
Published: September 2020

The Israeli army’s policing since 1967 has raised public awareness of the suffering of the Palestinian population, thereby implicating it as a key player in the Israeli political debate. This article discusses how policing has been presented in the leading military journals Ma’arakhot and Bein HaKtavim from 1967 to 2018. It argues that this coverage has served to mitigate the controversy by avoiding the explicit term ‘policing’ and replacing it with euphemisms that construct it differently in three distinct periods. In particular, since early in the twenty-first century, these journals have suggested alternative terms, which provide policing with hybrid military connotations that respond to pressure from both nationalist and liberal groups. New terms such as ‘the war between the wars’ promote broad public acceptance of the intractable nature of the conflict and legitimize the need to use violence.
Military-Police Fusion at the Southern Border
Authors: Brownfield-Stein Chava
Published: September 2020

Examining the activities of the Israel Defense Forces along the Gaza-Israel border, this article identifies a new phase in what the author calls ‘military-police fusion’. The analysis focuses on novel technologies—remote-controlled weapon stations and unmanned ground vehicles—and on the women soldiers who operate these systems. The central claim is that the blurring of boundaries between military and policing missions, combined with high-tech weaponry, has resulted in the development and implementation of new modes of violence that are currently undergoing a process of redefinition and feminization. The article addresses three key dimensions of the processes occurring in the hybrid operational environment along the Gaza-Israel border: the legal dimension, the technological dimension, and the gender dimension.

Authors: KIMAV Ali Ulus , AYDIN Belgin
Published: September 2020

The developments in the digital age are reflected in foreign language classrooms today, yet, teachers’ incompetence resulting from insufficient training about various technologies during their previous education prevent them from integrating technology into their classrooms effectively. Especially with the sudden increasing demand of online teaching due to COVID-19, there is a strong need to handle this issue as teachers continue doing their jobs. However, due to many reasons, in-service teacher training programs have been the subject of criticisms. This paper explains a blueprint for designing and implementing a context-specific in-service teacher training program for using web 2.0 tools in EFL lessons. The participants were 122 English language teachers working at the School of Foreign Languages at Anadolu University. Survey forms were utilized as data collection tools in this design-based study. Eight successive stages were followed in the training program. The feedback gathered both from the learners and the teachers show that both groups appreciated technology integration and the in-service teacher training program. Thus, based on overall findings, this blueprint can be suggested and developed for similar institutions wishing to increase their teachers’ competencies in integrating technology into their classrooms.

Published: September 2020

Industry 4.0 is causing a lot of changes related to the way people work, bringing a demand for a new worker profile, mainly for engineers, that need to have not only technical skills but also methodological, social and personal skills. So, there is a need to study and identify how the university prepares engineering students for Industry 4.0 jobs. To achieve this objective a literature review was made, twenty-nine skills of Industry 4.0 jobs were identified, and eight active learning methodologies were selected like paths that universities can use to develop skills for the Industry 4.0. To analyze how a university can use active learning methodologies to develop Industry 4.0 skills in engineering students, a questionnaire was applied in four engineering classes of the University of Brasilia, where the professors answered about the active learning methodology used and what skills were developed in the students, and the students answer the questionnaire with what skills they developed. A correlation analysis was applied to detect the different points of view between professors and students. Then, a decision tree was used to identify what skills were most developed by the active learning methodology used by the professor. The results show that are some divergences between the two points of view, and the questionnaire needs to be adaptable to measure with more reliability the skills that the professor wants to develop in each engineering class.
Using AutomationML and Graph-Based Design Languages for Automatic Generation of Digital Twins of Cyber-Physical Systems
Authors: Beisheim Nicolai , Kiesel Markus , Linde Markus , Ott Tobias
Published: September 2020

The interdisciplinary development of smart factories and cyber-physical systems CPS shows the weaknesses of classical development methods. For example, the communication of the interdisciplinary participants in the development process of CPS is difficult due to a lack of cross-domain language comprehension. At the same time, the functional complexity of the systems to be developed increases and they act operationally as independent CPSs. And it is not only the product that needs to be developed, but also the manufacturing processes are complex. The use of graph-based design languages offers a technical solution to these challenges. The UML-based structures offer a cross-domain language understanding for all those involved in the interdisciplinary development process. Simulations are required for the rapid and successful development of new products. Depending on the functional scope, graphical simulations of the production equipment are used to simulate the manufacturing processes as a digital factory or a virtual commissioning simulation. Due to the high number of functional changes during the development process, it makes sense to automatically generate the simulation modelling as digital twins of the products or means of production from the graph-based design languages. The paper describes how digital twins are automatically generated using AutomationML according to the Reference Architecture Model Industry 4.0 (RAMI 4.0) or the Industrial Internet Reference Architecture (IIRA).

Authors: Helmann Alexandre , Deschamps Fernando , Loures Eduardo de Freitas Rocha
Published: September 2020

Currently, production systems are receiving the application of more advanced, integrated and connected technologies to optimize the performance of their manufacturing processes. The new technological solutions demand architectures that support intelligent solutions for a new digitalized industry. However, production systems already in operation have difficulty in implementing these technologies. The existing barriers limit the availability of the direct integration of different systems contemplated in an automation system architecture. This article systematically reviews the existing literature to portray the characteristics of each architecture and that can guide the adoption of new technologies. Through this review, emerging reference architectures were identified, such as RAMI4.0, IIRA, IBM Industry 4.0 and NIST Smart Manufacturing. In conclusion, the article presents a framework for considering which model best fits with the new technological solutions.
Application of Innovative Tools to Design Ergonomic Control Dashboards
Authors: Grandi Fabio , Peruzzini Margherita , Campanella Claudia E. , Pellicciari Marcello
Published: September 2020

Designing highly usable and ergonomic control dashboards is fundamental to support the user in managing and properly setting complex machines, like trains, airplanes, trucks and tractors. Contrarily, control dashboards are usually big, intrusive, full of controls and not really usable for different users. This paper focuses on the re-design of an ergonomic and compact dashboard for tractor control, proposing an innovative methodology in line with human-centered design and ergonomics principles. The study started by shifting the focus from how a machine works to how a task has to be performed and how the user interacts with the machine. It uses virtual simulations and human performance analysis tools to support the concept generation and the detailed design, and to test the new idea with users in the virtual lab. Indeed, within the virtual environment, different configurations of controls can be tested, checking which controls are mostly used and measuring human performance indexes (i.e., postural comfort and mental workload) for each configuration. Virtual mannequins can be used to as “digital twins” to interact with virtual items and to calculate robust comfort indicators during task execution. The study adopted the proposed methodology to an industrial use case to develop a usable and compact armrest for a new tractor platform. The new armrest is smaller than the previous one (-30% in dimensions), more usable (keeping on board only frequent controls, better positioned), and more comfortable (it satisfies 95% of the population size). This new approach could be used also for the design of new products.
Stamping Tools for Sheet Metal Forming: Current State and Future Research Directions
Authors: Jonsson Carl-Johan , Stolt Roland , Elgh Fredrik
Published: September 2020

Sheet metal forming tools play an important role in the manufacturing of many products. With shorter product life cycles and demand for shorter time to market for new products, the process for design and manufacturing of stamping tools becomes a critical part. Stamping dies are often designed and manufactured by smaller, specialized companies. For a tooling company, knowledge and experience is an important competitive advantage. Traditionally the design process has been characterized by being based on few key individuals with much experience and craftsmanship. To stay competitive in this market there is a need for more efficient processes, systems, tools and supports in order to become more industrialized. This paper presents results from a study of the state of practice in industry within progressive stamping tool design as well as a review of relevant literature. The design and manufacturing processes for stamping dies in six companies have been investigated through semi-structured interviews, from which the main challenges in the current state for the companies are identified. The results from the interviews was analyzed and compared to the established concepts and frameworks of methods found in the literature review. The results and analysis points in the direction of efforts needed in supporting the formalization and reuse of information and knowledge from previous tool projects and production, especially during the critical steps of tool process planning and creating the tool layout.

Published: September 2020

In Industry 4.0, current trends on data analysis and real-time processing are intertwined with the use of development tools while conceiving products. The quality of information plays a pivotal role in this process, as the heterogeneity of unprocessed data may result in issues that increase the product’s cost and development time. In this context, the Failure Mode & Effect Analysis (FMEA) is a tool that aids decision-making by presenting pre-processed useful data that can improve product design, maintainability and manufacturing. FMEA criteria, although standardised, has ramifications that have different impacts and weight in an organisation, which might end up resulting in subjective evaluations. To cope with this issue and improve the quality of the information in product development, this research proposes a Multi-Criteria approach to define the importance of FMEA criteria and their impacts in organisations in a real industrial scenario. This research is applied using a case on a Brazilian electronics manufacturer, using AHP and TOPSIS Multi-Criteria Decision Making (MCDM) methods. Findings show that by traditional methods different evaluators end up generating different data and weights on FMEA, resulting in different results. In this sense, the application of the Multi-Criteria methods ends up ranking the importance of criteria and evaluating the inputs from all departments, returning more precise information. Furthermore, the weighting scale of FMEA has been shifted to a customised scale for the organisation in the study, based on AHP, more suitable to their needs and following their perception, to support the decision-makers most assertively.

Published: September 2020

With the mature development of IoT techniques, smart PSS emphasizes the digital transformation of the traditional PSS, which is an ever-evolving and value-co-creation system with the participation of users through the whole product lifecycle, especially during the usage stage. Due to the frequent changes of usage situations, the smart PSS providers are supposed to evolve their product-service bundles according to the trends of usage situations. It is critical to determine what is the current uasge situation, thereafter to evaluate and select proper product-service bundles during the usage phase. In this article, we propose a context-aware approach to evaluate the smart PSS performance during the usage phase.
Verification of Flutter Method for the Purposes of Building a Very Flexible Wing Generative Model
Authors: Zenowicz Kamil , Skarka Wojciech
Published: September 2020

First step of aircraft design is calculation of initial parameters, based on assumptions determining flight parameters which designed aircraft should meet. During these calculations, it is possible to pre-detect structure instability called a flutter. These calculations are made based on the geometric parameters assumed in the first conceptual drawings of the flying vehicle. Assumed masses and speeds allow for preliminary analysis of forces acting on the structure. The next step is to determine the displacements and deformations occurring in the structure of the aircraft in different phases of flight and under different conditions. The article presents all the stages of wing analysis for a proposed stratospheric drone with a highly flexible wing structure. This analysis, after integration with CAD software, will allow for the preparation of a comprehensive generative model. The basic assumptions of the designed aircraft are: flight altitude, wings area, very extended or unlimited flight time, approximate flight speed, climbing time, hull parameters, rudder size and placement, wing profile and mass of the structure. These assumptions made it possible to carry out a preliminary analysis of loads, wing pressure distribution, lift force and total resistance force. The goal of the research is to develop a methodology of preliminary flutter analysis which can be easily integrated in the form of calculation backgound for generative model. This methodology has been developed to determine displacements, structure stability and critical vibration frequencies. CAD software after integration with constantly optimizing calculation software will allow the generation of optimal shape and structure rigidity for given initial assumptions.
Design Entropy Theory: A Novel Transdisciplinary Design Methodology for Smart PSS Development

Published: September 2020

Smart product-service systems (Smart PSS), as an emerging transdisciplinary paradigm, leverages smart, connected products (SCPs) and their generated services as a solution bundle to meet individual customer needs across different engineering fields. Owing to the advanced information and communication technologies, Smart PSS development differs from the existing product and/or service design mainly in three aspects: 1) closed-loop design/redesign iteration; 2) value co-creation in the context; and 3) design with context-awareness. These unique characteristics bring up new engineering design challenges, and to the authors’ best knowledge, none of the existing design theories can address them well. Aiming to fill this gap, a novel design entroy theory is proposed by adapting the information theory with engineering design. In this context, Smart PSS can be regarded as the information container. Hence, the closed-loop design/redesign iteration can be treated as the dynamic change of information and entropy in a balanced system. Meanwhile, the value co-creation process is considered as the exchange of accumulated information via the container. Lastly, the design context-awareness represents the process of eliminating entropy. As a novel prescriptive design theory, it follows Shannon’s information theory to determine the best solutions by considering the three characteristics integrally. It is envisioned this appraoch can largely facilitate today’s industrial companies’ digital servitization towards Industry 4.0 with better performance and user satisfaction.

Published: September 2020

The use of carbon fiber composites (CFCs) has become broad in many industries due to its superior properties compared to conventional materials. However, the increased demand coupled with environmental regulations has led to the development of different recycling methods for CFCs such as mechanical, thermal and chemical processes. Each recycling method has its own requirements and outputs along with some economic implications which need to be justified through cost modelling. This paper aims to identify current challenges associated with cost modelling of different processes for CFC recycling. The main challenges identified are grouped into three main categories such as technical issues, supply chain and market challenges.
In the Era of Digitalising Shop Floor Management: In Blissful Ignorance of Superfluous Work
Authors: Mathiasen John Bang , de Haas Henning
Published: September 2020

This study aims to understand the extent of superfluous work at shop floors and suggests some managerial opportunities for reducing superfluous work. Drawing on the abductive reasoning, the research systematically combines a theoretical conceptualisation of decision-making processes in a digitalised manufacturing with an empirical enquiry of a smart manufacturing. The paper reveals superfluous work if decision-making processes cross disciplinary and/or organisational boundaries. Superfluous work occurs because of lacking data and information to guide reflective thinking and knowledge sharing. In relation to high complex decision making the ongoing implementation of workarounds does also cause superfluous work. Prerequisites for reducing superfluous work are accessibility of applicable data to guide reflective thinking and knowledge sharing.

A capability model describes the complete set of features that an organization requires to execute its business model or fulfill its mission; the user’s environment must be increasingly included in the design and development of necessary and desired solutions. For this, the development of the model and its application are central issues. An account should be taken of legislation involving the protection of individuals’ personal data in any relationship involving the processing of information classified as personal data; as well as its impact on public and private companies across the country, considering any size and market segment, and taking into account the need to comply with legal requirements efficiently and sustainably, mitigating risk factors. Transdisciplinarity characterizes this research, as the digital transformation process integrates legal, technological aspects, risks, business analysis, good practices and standards of information technology management and digital compliance. This paper addresses this problem by analyzing the main areas of contribution to the assessment of process capability for digital transformation concerning cybersecurity in the context of personal data protection legislation. Finally, the main components of the future capability model are presented.

Summary. Aim: To study the state of purine metabolism in gastric (GAC) and pulmonary (PAC) adenocarcinomas and to assess its clinical and pathogenetic significance. Patients and Methods: One hundred and six male patients were examined, among whom were 63 subjects aged 34 to 79 suffering from GAC, and 43 subjects aged 24 to 76 suffering from PAC. In GAC, the ratio of the pyloric, corporeal and antral localization of the tumor and variant of overall gastric lesion accounted to 24:5:1:1; and that of the central and peripheral PAC was 2:1. Serum levels of purine metabolism products (uric acid, oxypurinol, adenine, guanine, xanthine, hypoxanthine) were measured and activities of xanthine oxidase, xanthine deaminase, adenosine deaminase and 5-nucleotidase were analyzed. Results: Purine metabolism disorders are observed in all GAC and 91% of PAC patients; among other things, hyperuricemia is observed in ¾ and ½ of cases, respectively; moreover, the nature of changes is more pronounced in gastric cancer and, in both groups of patients, these indices reflect the disease course severity, are associated with the neoplastic process localization, have a predictive value, trigger the development of metastases. Conclusion: Сhanges in purine metabolism are involved in the pathogenetic patterns of GAC and PAC, reflect the course of the tumor process, are associated with tumor localization and have prognostic significance.
