Authors: Bordeasu I , Cernescu A , Ghera C , Opris C , Pirvulescu L.D 
Published: December 2024

Abstract
Cavitation erosion is a severe phenomenon of hydrodynamic equipment, determining their removal from use due to the continuous damage of the materials from which they are made. Intensive research is carried out to characterize the cavitation erosion phenomenon and also to determine the cavitation erosion strength of materials. These researches highlighted that the material damage through cavitation is characterized by fracture mechanisms specific to low-cycle fatigue. Few studies are reported on the combined action of cavitation erosion and mechanical loads. For this reason, the paper presents a study on the influence of cavitation erosion on the fatigue behaviour of a structural high-strength steel. Fatigue tests were performed on two sets of samples, eroded by cavitation and non-eroded. The results highlighted a different influence of cavitation erosion on fatigue life of the material, depending on the magnitude of the variable stress.

Authors: Talić H , Ćehić M 
Published: December 2024

Abstract
The favorable characteristics of veneer boards—plywood—enable their wide application. There is also the possibility of enhancing plywood, such as by coating it with various films, applying coatings, reinforcing it with fibers from different materials, and using improved adhesive formulas. Basalt fibers, as a natural and environmentally friendly material, are used in various forms with quite good characteristics. Results from various tests conducted in recent years indicate an improvement in the mechanical properties of composite boards, including plywood reinforced with fibers like basalt fibers. These tests were focused on determining the position and contribution of basalt fibers in the board’s structure, as well as the application of certain environmentally friendly adhesives. For this study, samples of composite material based on wood, specifically plywood reinforced with a basalt mesh, were prepared. The basalt mesh was placed within the plywood structure in various combinations of position and amount. Subsequently, a three-point bending strength test was conducted to determine the impact of the basalt mesh on the strength of the plywood. The increase in strength opens up possibilities for expanded use, material savings, and a reduction in the overall weight of the structure, which is crucial in certain applications of such boards.

Authors: Islamovic Cavkic B , Mijovic B , Bajramovic E 
Published: December 2024

Abstract
It is essential to know the mechanical properties of a material used in a structure to determine its purpose and lifespan. These properties largely depend on the material’s creation process and chemical composition. The verification of mechanical properties is done by performing standard test methods. These tests confirm if the material’s characteristic properties stated in certificates and other documents from the supplier are accurate. This paper explains the procedure of experimental testing of different aluminum alloys through tensile tests using standard test tubes made of three types of alloys - EN AW 5083, EN AW 6082, and EN AW 7075. The test results are shown diagrammatically as the elongation-stress dependence and the values of the fundamental mechanical properties were read. The methodology of experiments according to the standards for this type of test was covered, and finally, the analysis and comparison of the results obtained were performed depending on the type of material.

Under a not so white sky: visual impacts of stratospheric aerosol injection
Authors: Lemon Ansar , Keith David W , Albers Steve 
Published: December 2024

Abstract
Stratospheric aerosol injection (SAI) could change the sky’s appearance. This could play a role in shaping public perception of SAI. Noticeability depends strongly on tropospheric aerosol optical depth (AOD) and the amount of SAI used. We aim to quantify the noticeability of changes in sky color and brightness due to SAI. We use a 3D visible light radiative transfer package to generate cloudless sky images during high sun, sunset, and twilight under SAI from the reference point of a ground observer. We consider three aerosol types: H2SO4, CaCO3, and diamond. We consider stratospheric aerosol loadings required to produce radiative forcings of −1, −2, and −4 W m−2. We use population density and AOD data to compute the distribution of AODs people experience and then simulate sky images for the 10th, 50th, and 90th percentiles of that distribution. We compare the simulated changes in color and brightness to experimental measurements of minimum thresholds humans can detect. The three aerosol types cause similar changes, except most notably the diamond aerosol increases brightness of the solar aureole by roughly three to five times less than do H2SO4 or CaCO3. During high sun, sky whitening from sulfate SAI at −2 W m−2 is undetectable for roughly half of observers chosen randomly from the global population. For the remainder of the population, we expect whitening to still be unnoticeable for all but perhaps the most astute observers aided by color samples. Brightening and enlargement of the solar aureole is the most visible feature during high sun for H2SO4 and CaCO3, while changes near twilight would be the most noticeable impact of SAI. We cannot evaluate the fraction of the population who would notice these changes.

Published: December 2024

Abstract
The study analyzes the level of digital transformation in the regions of Ukraine based on a cluster analysis of key DESI subindices. Significant discrepancies in the levels of digitalization between different regions were identified, which are explained by economic development, infrastructure capabilities, and the impact of military actions in the east of the country since February 2022. Regions such as Dnipropetrovsk, Lviv, and Kyiv demonstrate high levels of digital transformation due to active implementation of digital technologies and investments in infrastructure. Recommendations are proposed to address digital inequality and enhance the digital capabilities of regions, which is a crucial step toward the sustainable development of Ukraine and its integration into the EU.

Published: December 2024

Abstract
The study examines the influence of the state oversight of rural development on the export of agricultural products in the new conditions of international trade and decentralisation. The key areas and priorities of the government oversight of fisheries, organic aquaculture, and animal husbandry adjusted to secure food supply in individual foreign countries are revealed. Calculations confirm that exports to Europe account for a significant share of deliveries and, from 1996 to 2021, by about 9.9 times, to Asia increased by about 2.7 times. The study suggests ways of improving rural development regulation for domestic alternatives to agricultural imports, considering decentralisation and the impact of international trade. The domestic agricultural sector faces instability due to its reliance on imported products and the pressures of international market competition. and livestock farming in many countries. Decentralisation of regulation and agriculture management leads to efficiency, sustainability and competitiveness.

Authors: Savchenko M , Radchuk O , Gerasimenko V , Chepizhnyi A 
Published: December 2024

Abstract
A methodology for calculating the consumption of combined alternative energy sources is proposed. The provision of electrical energy to the mini–workshop area for 7 hours a day with equipment that constantly consumes 5.5 kW of electricity was considered. The amount of electrical power needed to meet daily needs has been calculated. It is Rd = 38.5 kWh. Solar stations’ daily solar energy output is determined by considering the required backup power. It is Rst = Rd ·2 = 77.0 kWh. The total power of the solar panels is found. It is Rsp = 9.7 kW. The number of solar panels for the proposed Solar LR5-54HTH-435M example is calculated as several panels Nnp = 23.3 pieces. An inverter with more than 5.5 kW was selected in the given example. Anern EVO-6200 has a power of 6.2 kW and an input for connecting a 48 V battery. Its technical characteristics are presented. A scheme for connecting 24 solar panels was proposed, connecting 12 in series into one electrical circuit. There should be two such chains that are connected in parallel. The calculation is made for a Jarrett 120Ah 12V battery. Its capacity is Rb = 1440 Wh. The battery has the technical ability to store 1440 Wh of electrical energy. The batteries should be Nb = 17.4 pieces ≈ 20 to provide a mini–workshop. The choice of a storage station with 20 pieces of Jarrett 120Ah 12V batteries was justified.

Published: December 2024

Abstract
The limestone potential in Puger District serves as an economic attraction, ranging from household-scale lime processing to international cement production. Consequently, residential areas in the industrial zone have been increasing annually. The Job Creation Law emphasizes that residential areas should have adequate infrastructure and public utilities, making infrastructure planning crucial around the dry and dusty limestone hills. Mobilizing vehicles transporting limestone affects road quality and damages drainage systems, compromising water quality. Effective planning is essential to maintain infrastructure sustainability and prevent damage from the limestone industry. This article examines the impact of lime processing industries on basic infrastructure in residential areas, including road networks, drainage, sanitation, clean water, and waste management. The research utilizes the Likert scale to assess changes in infrastructure quality, followed by the Pareto method to identify dominant factors and triangulation for area planning recommendations. Findings indicate that all infrastructure is in moderate condition, with Pareto analysis revealing that 75% of the infrastructure is significantly affected, particularly in roads, clean water, and waste management. Recommendations include conducting a Level of Service (LOS) analysis for road infrastructure and integrating road paving with drainage lighting. It is advised to combine primary, secondary, and tertiary systems for drainage. Equitable distribution of the regional water supply system (PDAM) and regular water quality testing are recommended in clean water management. Increasing waste banks and strategically placing trash bins in public areas is suggested for waste management.

Authors: Pöschl Irmina , Weil Jonas , Kleberger Johannes 
Published: December 2024

Abstract
A digital ground model was elaborated for the design and construction phase of the Yusufeli Hydropower Project in Turkey, including a 275m high double curvature arch concrete dam. For the executive dam design the geotechnical model had to deliver attributes that were particular regarding the detail and scale of geotechnical volumes. A rock mass classification scheme was developed, that took into consideration these design requirements as well as special site conditions. Besides standard rock mass classifications, the methods applied included large-coverage E modulus logging and digital techniques for analysing factual data, employing automatised queries and intersecting parameter distributions in 3D space. Using these digital methods, a robust and reproducible geotechnical model was created. Meanwhile the dam was completed and impounded successfully.
A Data-Driven Approach to Mapping Rock Mass Discontinuities
Authors: Hurtgen M , Detert R 
Published: December 2024

Abstract
The characterization of rock mass is vital to the development of a mine. Understanding and monitoring rock mass discontinuities plays a vital role in the continued stability of a mine. Current methods of data collection are often time-consuming, disruptive, unsafe, or complex. New scanning technologies have the power to change how rock mass is characterized. The proposed workflow for rock mass data collection can be done simply, with little to no disruption to production, and with high levels of accuracy. By using a combination of point cloud data and 3D meshes, discontinuities can be easily and safely detected and classification data from them can be extracted and interpreted. This new method for rock mass classification and the mapping of rock mass discontinuities uses a simple workflow that is highly accurate and mitigates the risk typically faced when collecting data at the face. This workflow involves the collection of point clouds and 3D meshes in any area of interest that can then be instantly analyzed in modeling software to identify and analyze discontinuities and collect the dip direction and dip angles directly from the surface. With this proposed process, new measurements can be made in a timely manner at any point with a high degree of accuracy removing any human error from the data collection process.
Transfer learning based tunnel boring machine advance classification
Authors: Unterlass Paul J. , Erharter Georg H. , Marcher Thomas 
Published: December 2024

Abstract
Tunnel Boring Machines (TBMs) are well established in modern tunnel construction, with monitoring and predicting TBM performance being crucial for project timelines and risk mitigation. Machine Learning (ML), offers promising avenues for analysing TBM operational data. Transfer learning, a technique of ML, enhances classification tasks by leveraging knowledge from one domain to another, making it particularly relevant for TBM tunnelling where labelled data may be limited. This paper proposes a novel approach to TBM advance classification using a recurrent neural network (RNN) trained via transfer learning. By training the model on one dataset and transferring it’s knowledge to another, the study aims to classify TBM advance as regular- or exceptional advance based on TBM operational data. Transfer learning offers advantages for classification tasks in tunnelling by reducing the need for extensive labelled data collection at each site. Results showcase the RNN’s performance on datasets from the Norwegian Ulriken and Follobanen tunnels. The experiment highlights the model’s effectiveness in classifying regular advance, while classification of irregular advance shows some room for improvement. Overall, this research contributes to advancing ML applications in TBM tunnelling, and underscores transfer learning’s potential to streamline performance analysis and decision-making processes in tunnelling projects.
Introducing groundwater on GSI: a practical approach based on tunnel rock excavation
Authors: Santa Cláudio , Chaminé Helder I. , Fernandes Isabel 
Published: December 2024

Abstract
Groundwater flow on fractured rock mass is critical to understand the geotechnical behaviour. Water can influence the strength of the rock material and promote the washing of discontinuities’ filling. It also reduces the friction angle and shear resistance of the rock mass, creating additional pressure on the rock structure. This framework in rock mass behaviour is considered within the rock mass classifications usually applied in geotechnical characterisation and rock engineering evaluation for engineering design, namely underground works. Water is, in fact, steadily a disadvantage in engineering works. The GSI (Geological Strength Index) is increasingly becoming one of the most widely used geotechnical indexes in large rock engineering projects. This study aims to introduce groundwater into the GSI (version 2013) classification system. The practical implications for geoengineering are that the proposed change integrating the groundwater in the GSI approach will improve the reliability and applicability of the classification system in rock engineering projects, thereby improving the technical-scientific scope, safety conditions and efficiency of underground works noticeably and immediately. This immediate impact highlights the pressing nature of this matter for geotechnics and rock engineering practices.

Elastic properties analysis and characterization of rock’s mineral using digital rock image
Authors: Setiawan M R , Suharsono  , Hidayat W , Fatkhan  , Latief F D E , Fauzi U 
Published: December 2024

Abstract
Rocks are composed of diverse materials, rendering them inherently complex. Numerous factors influence their mechanical and elastic properties. A diabase core was drilled and prepared for characterization and analysis in this study. This research aims to investigate the rock’s elastic properties using digital rock physics, leveraging mineralogical analysis conducted through XRD. Moreover, the process of separating matrix and pores will impact numerical calculations. Therefore, in this study, numerical calculations were performed on single and multiphase matrices to understand the influence of minerals on the elastic modulus of diabase rock. Characterization results indicate that the sample consists of Albite Calcian (Anorthic), Clinopyroxene, and Natrolite. These three minerals can be distinguished in digital image processing based on differences in density values. Numerical calculations reveal that an increase in the quantity of Clinopyroxene enhances static P-wave velocity. So, multiphase approach calculations yield velocity values almost identical to those obtained in the single-phase model with Albite Calcian matrix.
