Geotechnical and Structural Damages Caused by the 2023 Kahramanmaraş Earthquakes in Gölbaşı (Adıyaman)

On 6 February 2023, two independent earthquake pairs on the East Anatolian Fault Zone, with epicenters in Pazarcık (Mw = 7.7) and Elbistan (Mw = 7.6) districts of Kahramanmaraş province, caused great destruction. Adıyaman and Gölbaşı districts of this city are among the settlements most affected by the earthquake. Especially in the district where geotechnical damages are most observed, the destructive effects of earthquakes have been clearly observed in buildings with different structural systems. In this study, information is given about the earthquakes that hit the region and the fault zone where the earthquakes occur. Geotechnical and structural damages occurring in the villages and center of the district were evaluated within the scope of earthquakes and structural engineering. It can be stated that damages observed in the district center are generally caused by soil–structure interaction problems. The fact that masonry structures, which are widely used in rural areas, do not benefit from any engineering services has an impact on the level of damage. The main reason for the damages occurring in the reinforced concrete structures in the district is the reinforced concrete system that is not designed properly or not built in accordance with the design. This case study demonstrated the importance of earthquake–soil–structure interactions in line with earthquake-resistant building design principles.

Corrosion fatigue behaviour of Q690D high-strength steel considering the effect of coupling

During the service period of steel structures, the condition of suffering from environmental corrosions and fatigue loadings simultaneously widely exists. In this article, focusing on the corrosion fatigue behaviour of Q690D high-strength steel with consideration of the coupling effect, experimental research was conducted and the coupling effect was analysed. Corrosion fatigue coupling tests were performed with the method of electrolytic accelerated corrosion. The corrosion characteristics were studied and compared with the corrosion tests without loadings. Then, the corrosion fatigue S-N curve was established and compared with non-corroded and pre-corroded conditions. Morphology observations were carried out to further analyse the mechanisms of corrosion fatigue coupling. The results show that the fatigue resistance of Q690D high-strength steel deteriorated greatly compared with non-corroded and pre-corroded conditions, and the adverse effect of corrosion fatigue coupling on fatigue resistance cannot be neglected. The coupling effect under real engineering service conditions could be well represented with the adopted test method, taking into account the time dimension correlation between fatigue and corrosion. The established Q690D S-N curve under the corrosive environment provides important references for the residual fatigue life assessment of high-strength steel fatigue considering the effect of environmental deterioration.

Driving Organizational Effectiveness: Implementing Safe Agile Framework for Team Alignment in Large Organisations

Implementing the Scaled Agile Framework (SAFe) in large organizations is crucial for achieving organizational effectiveness, especially as they expand globally. The SAFe framework, initially designed for software development, has evolved to cater to diverse industries like health, manufacturing, engineering, and financial services. The study elaborates the significance of implementing SAFe agile framework for team alignment in large organisations. SAFe operates at four levels: Team, Program, Large Solution, and Portfolio. Efficient collaboration, communication, and coordination, the three Cs of SAFe Agile, are essential for synergy across these levels. To practically implement SAFe and achieve team alignment, organizations should follow ten SAFe principles. These principles include taking an economic view, applying systems thinking, assuming variability, building incrementally with fast learning cycles, basing milestones on objective evaluation, ensuring uninterrupted value flow, applying cadence, unlocking intrinsic motivation, embracing decentralized decision-making, and organizing around value. Balancing bottom-up and top-down approaches through a middle-out method ensures effective SAFe implementation. This approach combines the strengths of methods, fostering cross-functional collaboration and effective communication channels from teams to the portfolio level. In conclusion, large-scale businesses may enhance organizational success through the transformational process of applying the SAFe framework for team alignment, which improves alignment, cooperation, efficiency, flexibility, and continuous improvement.

Monitoring the Expansion of Unplanned Urbanization and its Impact on Climate Change based on Google Earth Engine Service, a Case Study of Baghdad / Iraq

The earth's surface comprises different kinds of land cover, water resources, and soil, which create environmental factors for varied animals, plants, and humans. Knowing the significant effects of land cover is crucial for long-term development, climate change modeling, and preserving ecosystems. In this research, the Google Earth Engine platform and freely available Landsat imagery were used to investigate the impact of the expansion and degradation in urbanized areas, watersheds, and vegetative cover on the land surface temperature in Baghdad from 2004 to 2021. Land cover indices such as the Normalized Difference Vegetation Index, Normalized Difference Water Index, and Normalized Difference Built-up Index (NDVI, NDWI, and NDBI) were determined to examine the effects of land cover changes. In addition, the land surface temperature was calculated to assess urbanization expansion's impact on Baghdad's climate warming. The results showed a drastic decrease in vegetative cover and green land, on the other hand, a significant expansion in urbanized areas. Hence, from 2004 to 2021, the urbanized areas and open land rose by 37% and 3%, respectively, while the vegetative cover decreased by 41%. The maximum land surface temperature has risen 4° C, and the minimum land surface temperature has risen 2.5°C.

Challenges and Opportunities for Sustainable Engineering: Products, Services, Technologies, and Social Inclusivity with a Gender Approach

Today, sustainable engineering faces challenges, highlighting the need to develop sustainable technologies and systems to support these new engineering projects and services. These sustainable engineering challenges aim to achieve a balance between people and the planet. To this end, 17 Sustainable Development Goals and 169 targets have been formulated, constituting the internationally accepted global sustainability aspirations for 2030. To address this issue, it is necessary to characterize its product life cycle; if there are models for the integration of sustainable engineering in policies, strategies, and programs of public and private institutions, what would be its impact at economic and social levels and its sustainable social engineering, and how would the gender approach impact these areas since it is an inclusive part of the SDG 2030 and plays a relevant role? This research analyzes models of social inclusiveness, engineering products and services for sustainability, and integration into sustainable development goals of engineering products and technology, reviewing whether gender equality or equity is present in their application and development. This study highlights relevant initiatives and the most used technological tools. The PRISMA protocol directed this study, which identified 252 pertinent articles for analysis and suggested effective practices for employing products, services, and technologies to advance sustainable engineering in the near term.

THE EFFECT OF EXTRA FOODING ON THE FATIGUE OF FIELD WORKERS (TECHNICAL SERVICES) AT PT PLN (PERSERO) ULP MEDAN SELATAN

This research aims to investigate the effect of extra fooding on the fatigue of field workers at PT PLN (Persero) ULP Medan Selatan. This study considered the impact of additional food intake on fatigue levels, taking into account factors such as physical activity, rest time, working environment conditions, and the type of additional food consumed. The quantitative research method involved 20 engineering service workers who were given additional food in cucumber juice and coconut water. Data was collected before and after consuming extra food, with fatigue levels measured using a psychometrically tested rating scale. Descriptive statistical and regression analyses were performed to establish the relationship between extra food consumption and changes in fatigue levels. The results show that extra fooding has the potential to reduce fatigue in field workers, but the impact may vary depending on contextual factors. In conclusion, a holistic and integrated approach is needed in managing worker fatigue in the field, considering nutritional aspects and other factors that influence their working conditions.

An Investigation of the Cause of Delay in the Operationalization of Industrial Clusters in Zambia

The Zambian government, through the Citizens Economic Empowerment Commission (CEEC), sourced funding from the African Development Bank and constructed eight Industrial clusters in 2018, one in each of the following towns, Kafue, Chipata, Mongu, Ndola, Kitwe, Solwezi, Mansa and Kasama. These clusters were to be operational by 2019. However, as at June 2023, only three industrial clusters in Chipata, Kasama, and Mongu were operational. This paper reports the findings on the causes of the delay in operationalizing the constructed industrial clusters. A qualitative research design was used to identify the factors causing delay in the operationalization of the industrial clusters. The findings revealed that, inadequate funding by government was a major impediment on the operationalization of the industrial clusters accounting for about 42%, while management of CEEC, due to being politically inclined, accounted for 22.7%. The other factors are: change in government support strategy to small businesses, which necessitated remodelling of cluster buildings to accommodate cooperatives in the industrial clusters (19%), industrial clusters located in the outskirts of the central business districts (9.7%), and lack of engineering and information technology services (6.3%). This study recommends an industrial cluster implementation which is devoid of political influence, and independent management body.

Destructive impact of successive high magnitude earthquakes occurred in Türkiye’s Kahramanmaraş on February 6, 2023

AbstractTwo successive earthquakes with moment magnitudes of Mw = 7.7 (focal depth = 8.6 km) and Mw = 7.6 (focal depth = 7 km) occurred approximately within 9 h on February 6, 2023, in Türkiye, respectively. The epicenters were the Pazarcık and Elbistan districts of Kahramanmaraş. Both earthquakes occurred in the East Anatolian Fault Zone, one of Türkiye’s two major active fault systems. Between these two severe earthquakes, there was one more big aftershock with a moment magnitude of 6.6, the epicenter of which was in the Nurdağı District of Gaziantep. Then, on February 20, 2023, another aftershock earthquake with a magnitude of Mw = 6.4 occurred in Yayladağı district of Hatay. As a result of the earthquakes, severe damage occurred in several provinces and districts with a population of around 15 million, and more than 50,000 people have lost their lives. This study presents on-site geotechnical and structural investigations by a team of researchers after the Kahramanmaraş earthquakes. It summarizes the performance of the building environments as a result of on-site assessments, taking into account observed structural damage, local site conditions, and strong ground motion data. The possible causes of the observed damage are addressed in detail. These earthquakes once again revealed the common deficiencies of existing reinforced concrete structures in Türkiye, such as poor material quality, poor workmanship, unsuitability of reinforcement detailing, and inadequate earthquake-resistant construction techniques. Precast concrete and masonry structures in the region were also severely damaged during the earthquakes due to insufficient engineering service, poor materials, deficiencies during construction, etc.

ЭВОЛЮЦИЯ ТЕХНИЧЕСКОГО СЕРВИСА В АГРОПРОМЫШЛЕННОМ КОМПЛЕКСЕ

In the agro-industrial complex, the transition to a market economy has significantly affected the structure of the engineering service, which has not been reorganized taking into account the modern technical way of life. (Research purpose) The research purpose is determining the main stages of the transition period of the engineering service of the agro-industrial complex, reflecting the real possibilities of its revival based on the use of intelligent technologies. (Materials and methods) Conducted an in-depth analysis of changes in the engineering service of the agro-industrial complex over the past 25-30 years, reflecting the system of maintaining a high level of efficiency of agricultural machinery, the introduction of intelligent technologies in the technical support of machinery, the modernization of the system of providing engineering and technical services to agricultural producers. (Results and discussion) Showed the need to restore the basic parameters of an effective engineering service of the agro-industrial complex. We have determined the feasibility of ensuring a high level of efficiency of the machine and tractor fleet by optimizing the technical service on market conditions of voluntary and mutually beneficial for the owners of the equipment and the service provider. The need for the formation of a new ideology for the development of technical services in the agro-industrial complex related to the introduction of innovative technologies in agriculture based on highly efficient agricultural machinery using electronic means of monitoring and managing the technical condition of machines based on digital technologies has been identified. (Conclusions) The analysis of the state of technical service in the agro-industrial complex over the past 25-30 years makes it possible to substantiate the need to modernize the engineering service with the maximum use of intensive and intelligent technologies in order to implement the food program of the Russian Federation. Import substitution of agricultural machinery and all components related to its technical support is one of the main tasks, the solution of which largely depends on the successful modernization of the engineering service of the agro-industrial complex as part of the creation of domestic technological equipment and technologies.

ACHIEVING THE REQUIRED MACHINING ACCURACY BY CORRECTING ERRORS USING VARIABLES OF PARAMETRIC FUNCTIONS

Nowadays, the machine-building complex is actively saturated with high-tech equipment, without which an enterprise cannot enter the global market or keep up with its competitors. And it's not just about using systems with artificial intelligence elements as scientific and technical solutions to improve quality and reduce production costs. It is also about reducing the time required to prepare products for production and bringing them to the consumer ahead of schedule. Today, the most preferred method in the competitive struggle is to equip CAD/CAM production with computer-aided design systems. With their help, engineering and technology services cannot only design models of new products but also generate CNC control software for manufacturing parts on CNC machines. At the same time, program frames composed in G-codes have several drawbacks, the main one being a "rigid" algorithm of action, i.e., the lack of variability for final solutions when the required accuracy is achieved by correcting the numerical values of the coordinates of the points of formation of individual surfaces in the PC. In this case, the operator largely intuitively corrects individual program frames based on his or her own experience, which is almost impossible without appropriate calculations for controllers with linear-circular and angular motions. In addition, after some such changes, the program loses its geometric adequacy to the part drawing, and by correcting one element of the shaped profile, we invariably violate the laws of contact with neighboring elements specified in the drawing. The paper considers the analytical geometry apparatus that allows a line on a double curvature surface, the theoretical trajectory of tool movement, to be represented not as a set of scalar points but in a vector representation, considering its possible torsion. This approach is ensured by parametric programming with computational frames of point coordinates and logical transitions, determining the angles of inclination of the cutter axis relative to the normal to the surface in the case of multi-axis machining. However, the main advantage of this method is the ability to correct processing errors not by local changes in the numerical values of the coordinates, but by introducing correction coefficients into the equation of the shape formation trajectory - reactors for the appearance of errors in the shape or location of surfaces, arising, for example, from elastic movements. The value of the coefficients per group of personnel can be set in the process of research and industrial production and change depending on the properties of the blanks. For example, according to the current standards, variations in hardness of up to 10-12% were allowed for the blanks of rolling mill rolls. The article presents the experimental data of the research of the correction task in a parametric form and the results of their application for machining parts with radius cutters in real production..

Multi-Layer Digital Services Increase Developers’ Requirements to Agriculture IoT Platforms

Highlights Digital ecosystems in agriculture enable a new class of digital services that span over several layers of the IoT stack. This work defines digital ecosystems in agriculture based on IoT layers and utilized technologies. An example for a multi-layer digital service is developed, deployed, and tested using the NEVONEX Ecosystem. Surveys reveal software providers require more platform functionalities and early iteration testing on real farms. Abstract. In recent years, digital platforms in agriculture went through a phase of acquisitions and consolidation, where big players like agrochemical companies (Agrichems) and agricultural equipment manufacturers (OEMs) worked on expanding their technology stacks to build strategic portfolios of digital service offerings. To operate farm equipment efficiently, a combination of platforms and technologies is often needed, leading to the emergence of digital Agri-ecosystems. With the rising implementation of IoT technology, digital Agri-ecosystems enable multi-layer digital services and break down established categories (cloud-based and embedded). Content providers and developers creating those digital services face three options: aggregated cloud APIs (application programming interfaces), engineering service providers with proprietary technology stacks, and dedicated IoT ecosystems offering agnostic end-to-end workflows for development and deployment (first known example: NEVONEX). It is not yet fully understood how using an end-to-end IoT ecosystem changes developer requirements in comparison to existing solutions. Therefore, in this study, an example of a multi-layer digital service is developed and tested. Expert interviews (n = 21) explore relevant developer experiences and requirements. A consecutive survey (n = 30; NEVONEX developer conference) validates the findings. Results show that IoT- ecosystems speed up development and deployment cycles, save resources, and improve interoperability in operations. Engineering service providers remain very important players. Partner management, communication, abstraction of interfaces, testing infrastructure, and early end-user input are required by developers. In conclusion, IoT- ecosystems are beneficial for multi-layer digital service development; however, to fully satisfy developers and content providers, adjustments to platform functionalities and better testing opportunities on real farms are needed.

МІСЦЕ ІНЖИНІРИНГУ В ЖИТТЄВОМУ ЦИКЛІ ПРОМИСЛОВИХ ВИРОБІВ

In undertaking the exploration, the authors endeavored to disseminate to the readership a developed comprehension of the essence of engineering as a distinct form of economic endeavor and its positioning within the lifecycle of generating consumer value. Emphasis is placed on shipbuilding artifacts, considering their pivotal role in both the global and, by extension, national economies increasingly enmeshed within the international economic milieu. It is discerned that the upsurge in demand for Engineering services is attributable to the steep ascension in fleet size, notably within its most robust segment - the commercial sector. The doubling of the fleet size for transporting various types of cargo over the past twenty years has been confirmed by visualized statistics. This phenomenon is not merely a result of a surge in maritime freight transportation, which has increased by nearly three hundred percent over the analyzed period. Simultaneously, there is a growing interest among shipowners in extending the operational lifespan of vessels. In this context, they place hopes on vessel repair, modernization, and conversion. Furthermore, even the disposal of these complex engineering structures, in accordance with the requirements of the International Maritime Organization and the standards of the European Union and participating countries, should occur without causing harm to the personnel of specialized shipyards and the environment. It has been demonstrated that solving this problem is also impossible without engineering support. A model has been provided, defining the role of Engineering in the life cycle of industrial products (using shipbuilding as an example). It confirmed the working hypothesis regarding the parallel-sequential organization of relationships between Engineering and other stages of the life cycle of mechanical engineering products. Attention is focused on the fact that addressing the challenges that arise at each stage is facilitated by digital twins of physical objects. The "lives" of both are completely synchronized, as events occurring during the real-time operation of the offline object and their consequences are automatically reflected in the virtual "twin". This conclusion is of particular significance in the context of applying the concept and corresponding tools of Product Lifecycle Management in practice.

The purpose of this research is to comprehend how big data analytics affect engineering performance. The industrial part especially the engineering practice is among the most significant and delicate in the world. Gathering and manufacturing have a huge social impact on the economies of the nations and, consequently, on the lives of individuals all over the world. The potential for big data to completely alter engineering practice and enhance ongoing engineering projects. Many organizations appear to be aware of the advantages big data can bring to their performance in engineering practice, particularly its significant possible worth, but they encounter a number of challenges when implementing it, primarily because they are having trouble figuring out how to use the derived insights for their development. The development of new strategies and services is a crucial engineering activity, and it has been demonstrated to significantly affect an organization’s viability. If these insights are monetized, Organizations aiming for an improved engineering practice can build brand-new, customer-centered, and data-driven projects or both goods and services, providing a long-lasting competitive advantage and new revenue streams. According to empirical research, companies that have engineering practice incorporated with a data-driven approach that can show how big data contributes to improved performance, while those that have not yet instilled the entire organization struggle with an absence of comprehension on how to use big data technology to create potential value and accomplish their organizational goals. Due to the enormous strategic potential of big data, this article tries to conceptualize and investigate its effects on corporate performance. It also explores the impacts of big data on engineering performance because of its high strategic potential. Finally, it explores whether and how the creation of new engineering services and projects makes use of big data and related technologies. An in-depth SWOT, binary Logistic Regression analysis, and the use of grounded theory combine previous big data studies with several enterprises in Lagos, Nigeria’s Iganmu industrial layout area. The caliber of data gathered, data availability, legal considerations of data confidentiality and safekeeping, and highly qualified individuals working with big data are additional critical factors that influence the use of a data-driven approach. Therefore, in order for companies to achieve effectiveness and efficiency, they need to reflect on and make strategic decisions utilizing a comprehensive perspective on big data.
