  • Structural-Geotechnical Effects of the Foundation of a Medium-Height Structure
    Authors: V. Rodas, L. Almache, Keywords: interaction, soil, substructure, springs, effects, modeling, embedment DOI:10.5281/zenodo. Abstract: The interaction effects between the existing soil and the substructure of a 5-story building with an underground one, were evaluated in such a way that the structural-geotechnical concepts were validated through the method of impedance factors with a program based on the method of the finite elements. The continuous wall-type foundation had a constant thickness and followed inclined and orthogonal directions, while the ground had homogeneous and medium-type characteristics. The soil considered was type C according to the Ecuadorian Construction Standard (NEC) and the corresponding foundation comprised a depth of 4.00 meters and a basement wall thickness of 40 centimeters. This project is part of a mid-rise building in the city of Azogues (Ecuador). The hypotheses raised responded to the objectives in such a way that the model implemented with springs had a variation with respect to the embedded base, obtaining conservative results.
  • Gas Injection Transport Mechanism for Shale Oil Recovery
    Authors: Chinedu Ejike, Keywords: enhanced oil recovery, gas injection, shale oil, transport mechanism, unconventional reservoir DOI:10.5281/zenodo. Abstract: The United States is now energy self-sufficient due to the production of shale oil reserves. With more than half of it being tapped daily in the United States, these unconventional reserves are massive and provide immense potential for future energy demands. Drilling horizontal wells and fracking are the primary methods for developing these reserves. Regrettably, recovery efficiency is rarely greater than 10%. Gas injection enhanced oil recovery offers a significant benefit in optimizing recovery of shale oil. This could be either through huff and puff, gas flooding, and cyclic gas injection. Methane, nitrogen, and carbon (IV) oxide, among other high-pressure gases, can be injected. Operators use Darcy's law to assess a reservoir's productive capacity, but they are unaware that the law may not apply to shale oil reserves. This is due to the fact that, unlike pressure differences alone, diffusion, concentration, and gas selection all play a role in the flow of gas injected into the wellbore. The reservoir drainage and oil sweep efficiency rates are determined by the transport method. This research evaluates the parameters that influence gas injection transport mechanism. Understanding the process could accelerate recovery by two to three times.
  • Effect of Type of Pile and Its Installation Method on Pile Bearing Capacity by Physical Modeling in Frustum Confining Vessel
    Authors: Seyed Abolhasan Naeini, M. Mortezaee, Keywords: physical modeling, frustum confining vessel, pile, bearing capacity, installation method DOI:10.5281/zenodo. Abstract: Various factors such as the method of installation, the pile type, the pile material and the pile shape, can affect the final bearing capacity of a pile executed in the soil; among them, the method of installation is of special importance. The physical modeling is among the best options in the laboratory study of the piles behavior. Therefore, the current paper first presents and reviews the frustum confining vessel (FCV) as a suitable tool for physical modeling of deep foundations. Then, by describing the loading tests of two open-ended and closed-end steel piles, each of which has been performed in two methods, “with displacement" and "without displacement", the effect of end conditions and installation method on the final bearing capacity of the pile is investigated. The soil used in the current paper is silty sand of Firuzkuh, Iran. The results of the experiments show that in general the without displacement installation method has a larger bearing capacity in both piles, and in a specific method of installation the closed ended pile shows a slightly higher bearing capacity.
  • Investigation of Tbilisi City Atmospheric Air Pollution with PM in Usual and Emergency Situations Using the Observational and Numerical Modeling Data
    Authors: N. Gigauri, V. Kukhalashvili, V. Sesadze, A. Surmava, L. Intskirveli, Keywords: Air pollution, numerical modeling, PM2.5, PM10. DOI:10.5281/zenodo. Abstract: Pollution of the Tbilisi atmospheric air with PM2.5 and PM10 in usual and pandemic situations by using the data of 5 stationary observation points is investigated. The values of the statistical characteristic parameters of PM in the atmosphere of Tbilisi are analyzed and trend graphs are constructed. By means of analysis of pollution levels in the quarantine and usual periods the proportion of vehicle traffic in pollution of city is estimated. Experimental measurements of PM2.5, PM10 in the atmosphere have been carried out in different districts of the city and map of the distribution of their concentrations were constructed. It is shown that maximum pollution values are recorded in the city center and along major motorways. It is shown that the average monthly concentrations vary in the range of 0.6-1.6 Maximum Permissible Concentration (MPC). Average daily values of concentration vary at 2-4 days intervals. The distribution of PM10 generated as a result of traffic is numerical modeled. The modeling results are compared with the observation data.
  • Application of UAS in Forest Firefighting for Detecting Ignitions and 3D Fuel Volume Estimation
    Authors: Artur Krukowski, Emmanouela Vogiatzaki, Keywords: Forest wildfires, fuel volume estimation, 3D modeling, UAV, surveillance, firefighting, ignition detectors. DOI:10.5281/zenodo. Abstract: The article presents results from the AF3 project “Advanced Forest Fire Fighting” focused on Unmanned Aircraft Systems (UAS)-based 3D surveillance and 3D area mapping using high-resolution photogrammetric methods from multispectral imaging, also taking advantage of the 3D scanning techniques from the SCAN4RECO project. We also present a proprietary embedded sensor system used for the detection of fire ignitions in the forest using near-infrared based scanner with weight and form factors allowing it to be easily deployed on standard commercial micro-UAVs, such as DJI Inspire or Mavic. Results from real-life pilot trials in Greece, Spain, and Israel demonstrated added-value in the use of UAS for precise and reliable detection of forest fires, as well as high-resolution 3D aerial modeling for accurate quantification of human resources and equipment required for firefighting.
  • The Benefits of End-To-End Integrated Planning from the Mine to Client Supply for Minimizing Penalties
    Authors: G. Martino, F. Silva, E. Marchal, Keywords: Clusterization and classification algorithms, integrated planning, optimization, mathematical modeling, penalty minimization. DOI:10.5281/zenodo. Abstract: The control over delivered iron ore blend characteristics is one of the most important aspects of the mining business. The iron ore price is a function of its composition, which is the outcome of the beneficiation process. So, end-to-end integrated planning of mine operations can reduce risks of penalties on the iron ore price. In a standard iron mining company, the production chain is composed of mining, ore beneficiation, and client supply. When mine planning and client supply decisions are made uncoordinated, the beneficiation plant struggles to deliver the best blend possible. Technological improvements in several fields allowed bridging the gap between departments and boosting integrated decision-making processes. Clusterization and classification algorithms over historical production data generate reasonable previsions for quality and volume of iron ore produced for each pile of run-of-mine (ROM) processed. Mathematical modeling can use those deterministic relations to propose iron ore blends that better-fit specifications within a delivery schedule. Additionally, a model capable of representing the whole production chain can clearly compare the overall impact of different decisions in the process. This study shows how flexibilization combined with a planning optimization model between the mine and the ore beneficiation processes can reduce risks of out of specification deliveries. The model capabilities are illustrated on a hypothetical iron ore mine with magnetic separation process. Finally, this study shows ways of cost reduction or profit increase by optimizing process indicators across the production chain and integrating the different plannings with the sales decisions.
  • A Case Study on the Numerical-Probability Approach for Deep Excavation Analysis
    Authors: Komeil Valipourian, Keywords: Numerical probability modeling, deep excavation, allowable maximum displacement, finite difference method, FDM. DOI:10.5281/zenodo. Abstract: Urban advances and the growing need for developing infrastructures has increased the importance of deep excavations. In this study, after the introducing probability analysis as an important issue, an attempt has been made to apply it for the deep excavation project of Bangkok’s Metro as a case study. For this, the numerical probability model has been developed based on the Finite Difference Method and Monte Carlo sampling approach. The results indicate that disregarding the issue of probability in this project will result in an inappropriate design of the retaining structure. Therefore, probabilistic redesign of the support is proposed and carried out as one of the applications of probability analysis. A 50% reduction in the flexural strength of the structure increases the failure probability just by 8% in the allowable range and helps improve economic conditions, while maintaining mechanical efficiency. With regard to the lack of efficient design in most deep excavations, by considering geometrical and geotechnical variability, an attempt was made to develop an optimum practical design standard for deep excavations based on failure probability. On this basis, a practical relationship is presented for estimating the maximum allowable horizontal displacement, which can help improve design conditions without developing the probability analysis.
  • Evaluation of Numerical Modeling of Jet Grouting Design Using in situ Loading Test
    Authors: Reza Ziaie Moayed, Ehsan Azini, Keywords: Jet grouting column, Soil improvement, Numerical modeling, In-situ loading test. DOI:10.5281/zenodo. Abstract: Jet grouting (JG) is one of the methods of improving and increasing the strength and bearing of soil in which the high pressure water or grout is injected through the nozzles into the soil. During this process, a part of the soil and grout particles comes out of the drill borehole, and the other part is mixed up with the grout in place, as a result of this process, a mass of modified soil is created. The purpose of this method is to change the soil into a mixture of soil and cement, commonly known as "soil-cement". In this paper, first, the principles of high pressure injection and then the effective parameters in the JG method are described. Then, the tests on the samples taken from the columns formed from the excavation around the soil-cement columns, as well as the static loading test on the created column, are discussed. In the other part of this paper, the soil behavior models for numerical modeling in PLAXIS software are mentioned. The purpose of this paper is to evaluate the results of numerical modeling based on in-situ static loading tests. The results indicate an acceptable agreement between the results of the tests mentioned and the modeling results. Also, modeling with this software as an appropriate option for technical feasibility can be used to soil improvement using JG.
  • Economic Model of Sustainable Value Chain in Passenger Waterway Transportation Service
    Authors: Maisa Sales Gama Tobias, Paulo Sérgio Lima Pereira Afonso, Keywords: value chain, sustainability, waterway transportation, cost management, cost model DOI:10.5281/zenodo.3686877 Abstract: The service of passenger waterway transportation lacks economic models that help in designing and implementing strategies to ensure its sustainability in several aspects (economic, social and environmental). The size of costs, though not the only one, is of particular importance in these models. However, traditionally, cost management has been focused only on reducing production costs, for the purpose of companies to keep prices low and gain market competitiveness. Although, with all the technological advances, and other restrictions imposed by the market in terms of service, in the case of passengers waterway transportation: intermodal competition; quality of service; or by regulatory environment for public concession and; in the aspect of business: to stay in the market with natural, demand and institutional restrictions, this view is not enough. Thus, there is an evolution of a traditional cost accounting to strategic cost management. On the other hand, it is important to consider other important dimensions and recognize that companies no longer exist in isolation, but they are part of highly integrated value and supplies chains. Therefore, this work will explore and analyze the sustainable value chain of passenger waterway transportation service using the tools of strategic cost management. The method will start from three components of analysis: (1) definition of basic elements of sustainable value chain; (2) identification of main restrictions to the chain development and aspects critical for service sustainability; (3) development of a cost model and propositions to overcome the bottlenecks found, to add value. Whether in the internal cost structure of the company; operational cost reduction strategies; in search of new markets, or to establish new partnerships or even; in the broadest level, in terms of investments in infrastructure or recommendations involving governance decisions to improve the current institutional environment. The case study will be developed in passenger transport companies located in the Lower Amazon, consolidated in this market, with defined enterprise structure of business sustainability, and who have already been willing to collaborate with the investigation. As results, it is expected to understand the cost structures that support sustainable value chains, namely, costs of activities and relevant cost objects in order to determine the cost drivers, profitability margins, cost reduction opportunities and conditions conducive to competitive advantages related to the different strategic options to cost leadership, differentiation or approach. Finally, in the model to be developed, the proper characterization of cost structure and value creation in transport processes under study may constitute reference points for future more sophisticated applied works of optimizing the resources involved and supporting the decision making, in particular with regard to operations research and quantitative methods more robust.
  • Studying the Spatial Variations of Stable Isotopes (18O and 2H) in Precipitation and Groundwater Resources in Zagros Region
    Authors: Mojtaba Heydarizad, Keywords: Groundwater, precipitation, simulation, stable isotopes, Zagros region. DOI:10.5281/zenodo.3593226 Abstract: Zagros mountain range is a very important precipitation zone in Iran as it receives high average annual precipitation compared to other parts of this country. Although this region is important precipitation zone in semi-arid an arid country like Iran, accurate method to study water resources in this region has not been applied yet. In this study, stable isotope δ18O content of precipitation and groundwater resources showed spatial variations across Zagros region as southern parts of Zagros region showed more enriched isotope values compared to the northern parts. This is normal as southern Zagros region is much drier with higher air temperature and evaporation compared to northern parts. In addition, the spatial variations of stable isotope δ18O in precipitation in Zagros region have been simulated by the models which consider the altitude and latitude variations as input to simulate δ18O in precipitation.
