Authors: Kovalenko O. V. , Bohomazova V. M. , Kvasha T. K.
Published: October 2022

The article analyzes the regulatory legal acts of the European Union and Ukraine in the field of marine research and identifies key gaps in Ukrainian legislation. It has been established that the EU legislation provides for the observance of the principle of integration of science, industry, politics and society and pooling their resources for the financing of marine research. The priority thematic areas of European legal support in this field are: research on climate change, protection and recovery of marine biodiversity, ecosystem approach to resource management and spatial planning, renewable ocean energy, impact of human activity on coastal and marine ecosystems, generation of digital scientific knowledge about seas and oceans and free access to them, forming the foundations of a carbon-neutral and cyclical EU’s “blue” economy. It is noted that, despite the wide range of legislative acts adopted in Ukraine, which regulate the field of marine research, there is a dispersal regarding the directions of these researches, and the basic principles of their conduct are not defined. The priority areas of scientific marine research need to be determined. It is concluded that there is a need to form a more consistent policy regarding marine scientific research, to strengthen partnerships with the participation of all interested parties who mobilize and distribute knowledge, experience, technologies and financial resources in the interests of the sustainable development of water resources of Ukraine. This requires establishing the basic principles of conducting marine scientific research, applying a foresight approach to determine the priority areas of marine scientific research for Ukraine. After the approval of the Foresight’s results by the Decree of the Cabinet of Ministers, the main tasks are focus on these priority areas during forming a state order for conducting marine scientific research and annually monitor the implementation of the identified priorities and provide a report on the monitoring results.

Представлено технико-экономическое сравнение трех методов обеззараживания воды с использованием: газообразного хлора, высококонцентрированного гипохлорита натрия и низкоконцентрированного гипохлорита натрия. Сравнительный анализ проводили на примере действующей хлораторной, расположенной на территории канализационных очистных сооружений г. Ленинск-Кузнецкий Кемеровской области. Экономический анализ показал, что использование низкоконцентрированного гипохлорита натрия в сравнении с высококонцентрированным является выгодным, поскольку сокращается срок окупаемости. Это подтверждает целесообразность применения данной технологии и позволяет в большей степени реализовать социально ориентированную тарифную политику для потребителей. Кроме того, при выборе реагента его преимущества следует искать в безопасности доставки и хранения, технологичности применения, количестве побочных отходов при производстве продукта на месте использования, а также цены поставок хлорсодержащего реагента или стоимости аппаратов, производящих его непосредственно на площадке водоочистных сооружений из приобретаемого сырья.

An engineering and economic comparison of three methods of water disinfection using: gaseous chlorine, high concentrated sodium hypochlorite and low concentrated sodium hypochlorite is presented. A comparative analysis was carried out using the example of an operating chlorination plant located on the territory of the wastewater treatment facilities in the city of Leninsk-Kuznetsky, Kemerovo Region. The economic analysis has shown that the use of low concentrated sodium hypochlorite compared to high concentrated sodium hypochlorite is beneficial, as the payback period is reduced. This confirms the expediency of using this technology since it provides for implementing a socially oriented tariff policy for consumers to a greater extent. Besides, while choosing a chemical, its advantages should be sought in the safety of delivery and storage, technological effectiveness in use, the amount of by-products in the preparation of the product at the place of use, as well as the delivery price of a chlorine-containing chemical or the cost of apparatus that produce it directly at the premises of the water treatment facilities from purchased raw materials.

Road extraction from satellite images has several Applications such as geographic information system (GIS). Having an accurate and up-to-date road network database will facilitate transportation, disaster management and GPS navigation. Most active field of research for automatic extraction of road network involves semantic segmentation using convolutional neural network (CNN). Although they can produce accurate results, typically the models give up performance for accuracy and vice-versa. In this paper, we are proposing architecture for semantic segmentation of road networks using Atrous Spatial Pyramid Pooling (ASPP). The network contains residual blocks for extracting low level features. Atrous convolutions with different dilation rates are taken and spatial pyramid pooling is performed on these features for extracting the spatial information. The low level features from residual blocks are added to the multi scale context information to produce the final segmentation image. Our proposed model significantly reduces the number of parameters that are required to train the model. The proposed model was trained on the Massachusetts roads dataset and the results have shown that our model produces superior results than that of popular state-of-the art models.

Authors: Prabou Ashwin
Published: October 2022

With the rise of automation and machine learning in our world, we have to work with a mindset to use it for our safety and for others’ safety. This research paper aims to utilize two different machine learning models- K-Nearest Neighbors and Neural Networks - to try to find what is the best for vehicles to detect any oncoming dogs on the road. Through building several different models and comparing their overall accuracy, this research paper will answer the questions about the differences between the two models, and which one would be the most reliable for vehicles. The accuracy of the models are measured through several tests taking in 32x32 px images of both roads and dogs, and training and testing the different models.
On the Generation of Distributed Spherical Harmonics Expansions for Inverse Source Solutions
Authors: Eibert Thomas F. , Ostrzyharczik Daniel , Kornprobst Jonas , Knapp Josef
Published: October 2022

Distributed spherical harmonics expansions are a powerful approach for the efficient solution of inverse source problems. They allow for a relatively accurate representation of the geometric support of the source distribution without the overhead of handling a mesh and mesh-specific basis functions representing the commonly utilized surface current densities. Standard spherical harmonics expansions distributed over a Huygens surface around the source domain are, however, redundant. Therefore, we discuss ways towards the reduction of this redundancy, where we are in particular interested in the construction of spherical harmonics with predominant radiation into the actual solution domain. Several sets of such spherical harmonics are presented and their utilization with measured and synthetic near-field data is demonstrated.
AVO in thermoelastic media
Authors: Hou Wanting , Fu Li-Yun , Carcione José
Published: October 2022

Temperature is an important factor for evaluating the seismic response of deep reservoirs. We develop an amplitude variation with offset (AVO) approximation based on the Lord-Shulman (LS) thermoelasticity theory. The model predicts two compressional (P and T) waves (the second is a thermal mode) and a shear (S) wave. The T mode is due to the coupling between the elastic and heat equations. In the thermoelastic case, the approximation is more accurate than in the elastic case. Its accuracy is veried by comparison with the exact equations calculated in terms of potential functions. We examine two reservoir models with high temperatures and compute synthetic seismograms that illustrate the reliability of the approximation. Moreover, we consider real data to build a model, and show that the approximate equation not only simplies the calculations, but is accurate enough and can be used to evaluate the temperature-dependent elastic properties, providing a basis for further application of the thermoelasticity theory, such as geothermal exploration, thermal enhanced oil recovery, and ultra-deep oil and gas resources subject to high temperatures.

Photovoltaic single-diode model parametrization. An application to the calculus of the Euclidean distance to an I-V curve
Authors: Galiano Vicente , Toledo F. Javier , Blanes Jose M. , Herranz Victoria , Batzelis Efstratios
Published: October 2022

In this paper it is provided a new, the first one as far as the authors knowledge, parametrization of the I-V curve associated to the photovoltaic (PV) single-diode model (SDM), which is the most common model in the literature to analyze the behavior of a PV panel. The SDM relates, through a transcendental equation with five parameters to be determined, the voltage with the current. There are many methodologies to extract the SDM parameters and, some of them, are based on obtaining the best fit of a voltage-current data through the ordinary least squares method, however, the fact that errors affect not only the current but also the voltage indicates that the maximum likelihood estimation (MLE) of the parameters is obtained by the total least squares method, also called orthogonal distance regression (ODR). The main difficulty in performing ODR lies in obtaining the Euclidean distance from a point to the I-V curve which is, in general, a hard mathematical problem but, in our particular case, it is noticeably more difficult due to the implicit nature of the SDM equation and the fact that solution candidates might not be unique.  The new parametrization will allow to reduce the calculus of the Euclidean distance from any point to the I-V curve to solve a single-variable equation. An in-depth mathematical analysis will determine the number of possible candidates where the Euclidean distance can be attained. Moreover, a full casuistry together with a geometrical study based on the curvature of the I-V curve and the Maximum Curvature Point, will allow to locate and classify all these candidates, enabling to develop the first complete algorithm able to compute the Euclidean distance from a point to an I-V curve in any condition and, as a consequence, to perform a reliable ODR to obtain the MLE of the SDM parameters. Using the obtained theoretical background, it will be demonstrated that two existing methodologies to compute the Euclidean distance fail in some conditions. It will be shown that the proposed algorithm is even faster than the previous methodologies despite it needs to verify with casuistry the right selection of the solution.
Are Turn-by-Turn Navigation Systems of Regular Vehicles Ready for Edge-Assisted Autonomous Vehicles?
Authors: Atik Syeda Tanjila , Brocanelli Marco , Grosu Daniel
Published: October 2022

Future private and public transportation will be dominated by Autonomous Vehicles (AV), which are potentially safer than regular vehicles. However, ensuring good performance for the autonomous features requires fast processing of heavy computational tasks. Providing each AV with powerful enough computing resources is certainly a practical solution but may result in increased AV cost and decreased driving range. An alternative solution being explored in research is to install low-power computing hardware on each AV and offload the heavy tasks to powerful nearby edge servers. In this case, the AV's reaction time depends on how quickly the navigation tasks are completed in the edge server. To reduce task completion latency, the edge servers must be equipped with enough network and computing resources to handle the vehicle demands. However, this demand shows large spatio-temporal variations. Thus, deploying the same amount of resources in different locations may lead to unnecessary resource over-provisioning.

Taking these challenges into consideration, in this paper, we discuss the implications of deploying different amounts of resources in different city areas based on real traffic data to sustain peak versus average demand. Because deploying edge resources to handle the average demand leads to lower deployment costs and better system utilization, we then investigate how peak-hour demand affect the safe travel time of AVs and whether current turn-by-turn navigation apps would still provide the fastest travel route. The insights and findings of this paper will inspire new research that can considerably speed up the deployment of edge-assisted AVs in our society.

A Hybrid 3-D MLFMM-PE Method for ILS Channel Modeling over Large Scale Environment
Authors: Li Zihao , Wu Xiaoping , Lu Yongdong , Wang Mingjia , Long Yunliang
Published: October 2022

This letter presents a novel 3-D hybrid method for instrument landing system (ILS) channel modeling, which names half space multilevel fast multipole method - parabolic equation method (HSMLFMM-PE). The multilevel fast multipole method (MLFMM) is applied to simulate the source region and near source obstacles. The large scale obstacles, pertaining to the far field region, is implemented by the parabolic equation (PE) method. The transition plane between the MLFMM region and PE region is solved by the half plane Green's function of the MLFMM to avoid the full wave simulation of the ground, thus the computation cost can be further reduced. Experimental results demonstrate that the computation cost of half space method is lower than full space method. The HSMLFMM-PE method can simultaneously meet the requirements of high simulation accuracy and the requirements of large area radio wave propagation computation in ILS simulation.
A Multipath Mitigation Based on Metallic Reflective Structure for Aircraft ILS Landing on Complex Obstacles
Authors: Li Zihao , Wu Xiaoping , Lu Yongdong , Wang Mingjia , Long Yunliang
Published: October 2022

The aircraft's landing is guided by the instrument landing system (ILS). However, the guidance information may be disturbed by reflections from irregular terrain and obstacles. A sketch which restrains the multipath effect from irregular terrain and obstacles, is then required. This paper proposes a metallic reflective structure which aims at blocking the radio wave directly radiating to the terrain. The design of the structure size and location is based on the location of the obstacles and the radiation pattern of the antenna. Due to the fact that the scattering effect of the structure should be accurately simulated, the finite difference time domain - parabolic equation method (FDTD-PE) is applied in ILS and used to simulate the interaction of the scattering effect between the structure and the terrain. The experimental results show that the proposed method improves the multipath effect mitigation.

Latar Belakang :  Perawatan ulkus diabetik dengan lidah buaya dan gula aren merupakan salah satu upaya tindakan perawatan untuk mencegah infeksi pada ulkus diabetik. Lidah buaya mengandung auksin, gibber-relin, antrakuinon, vitamin A, C, E sebagai antiinflamasi, antipiretik, antioksidan, antiseptik, antimikroba, serta  antivirus.  Lidah  buaya  mampu  berdifusi  secara  baik dan mampu menahan hilangnya cairan tubuh dari permukaan  kulit sehingga terjaga kelembabannya, sedangkan gula aren mengandung vitamin C, Riboflavin, vitamin A, dan ascorbic acid sebagai antibiotik dan meningkatkan sistem kerja jaringan yang dapat melemahkan dan membunuh bakteri penyebab terjadinya infeksi pada ulkus diabetik.

Tujuan : Tujuan penelitian ini mengetahui pengaruh kombinasi lidah buaya dan gula aren terhadap perbaikan ulkus diabetik pada pasien diabetes melitus tipe 2.

Metode : Desain penelitian one group pretest and postest design pada satu kelompok subjek dengan jumlah sampel 8 orang, teknik pengambilan sampel menggunakan consecutive sampling, penelitian dilaksanakan selama bulan Agustus 2022 di puskesmas Wanaraja Kabupaten Garut

Hasil : . Hasil penelitian menunjukan, nilai rata-rata ulkus diabetikum pre-post treatment perawatan ulkus diabetik dengan kombinasi lidah buaya dan gula aren adalah 24,875 dengan standar deviasi 6,034. Hasil uji  t-test dependent didapatkan p value 0,000 yang mempunyai makna media kombinasi lidah buaya dan gula aren berpengaruh terhadap perbaikan ulkus diabetik pada pasien diabetes melitus tipe 2. Adanya proses perbaikan ulkus diabetik disebabkan oleh peningkatan proses osmosis antara eksudat pada daerah ulkus diabetik dengan kombinasi media kedua bahan perawatan ulkus yang diberikan, sehingga meningkatkan penyerapan eksudat pada ulkus diabetik ke media perawatan luka tersebut. Selain itu, kombinasi dari lidah buaya dan gula aren mampu menahan hilangnya cairan tubuh dari permukaan kulit yang memudahkan epitel dari tepi luka bermigrasi ketempat luka bersamaan dengan kontraksi miofibroblast yang akan menutup luka.

Kesimpulan: Simpulan penelitian, kombinasi lidah buaya dan gula aren berpengaruh terhadap perbaikan ulkus diabetik pada pasien diabetes melitus tipe 2.
