Authors: Tubalawony Simon , Huwae Ana Yeti 
Published: December 2024

Upwelling merupakan naiknya massa air di lapisan bawah ke permukaan. Naiknya massa air dikarenakan adanya angin yang bergerak di atas perairan sehingga angin ini akan mendorong massa air di permukaan akibatnya air yang berasal dari bawah menggantikan kekosongan yang berada diatas. Variasi sebaran SPL relatif lebih rendah dan kelimpahan klorofil sebagai indikator terjadinya fenomena upwelling serta pengaruh angin terhadap fenomena upwelling. Tujuan dari penelitian ini adalah untuk mengetahui variabilitas SPL dan klorofil pada perairan Selatan Pulau Buru hingga Pulau Seram dan pengaruhnya terhadap fenomena upwelling. Metode yang digunakan adalah metode kuantitatif dengan tujuan untuk menggambarkan keadaan SPL dan Klorofil di Perairan Selatan Pulau Buru hingga Pulau Seram. Hasil penelitian menunjukkan analisis sebaran SPL dan klorofil dari bulan Juni sampai bulan Oktober merupakan fenomena terjadinya upwelling dengan SPL bulan Juni 28.15°C dan klorofil-a 0,44 mg/m3 dengan rata- rata kecepatan angin 4,58 m/s yang merupakan awal terjadinya fenomena upwelling. Untuk bulan Juli sebaran SPL 27,21°C dan klorofil-a 0,54 mg/m3dengan rata- rata kecepatan angin 5,42 m/s. Bulan Agustus sebaran SPL 26,95°C dan klorofil-a 0,58 mg/m3dengan rata- rata kecepatan angin 5,32 m/s.

Convolutional Double Radial-basis Neural Network Based on Special Type of Kernel Functions
Authors: Chala Olha S. 
Published: December 2024

In the article, the convolutional double neural network that has kernel activation function was proposed. It is designed to solve image recognition-classification task in online mode. The neural network has two blocks, where the first one is autoencoder, and as a matter of fact is a modified probabilistic neural network and receives on its input images in their initial matrix form. The output is represented as a vector-signal of the pre-classification, where the length of the vector is defined by the number of classes in a dataset. Then this vector is fed to the input layer of the second block - radial-basis neural network that forms separating hypersurfaces between arbitrary complex form classes.
The distinctive feature of the proposed system is the combined learning of both blocks of the system, where the first one is tuned by the paradigm of lazy learning, basing on the concept «Neurons at datapoints», and the recognition system follow by the paradigm of supervised learning where synaptic weighs, centers and receptive fields of activation functions are tuned. Following this learning approach, the system is characterised by high accuracy and learning speed, which allows classification of data streams as the sequence of images that are fed in the system in online mode.

Determining Mechanical Strength of Composite Traverse for 6-10 kV Overhead Power Line with Finite Element Method
Authors: Kochunov Yu. A. , Egorov D. V. 
Published: December 2024

Overhead power lines with a voltage of 6–10 kV, intended for power supply of signalling, centralised traffic control and signalling block systems and of electrical equipment along the railways use as supporting structures metallic traverses with porcelain or glass insulators. According to available data, defects caused by mechanical stresses account for more than half of the total number of disruptions in the normal operation of overhead power lines. It is worth highlighting defects that are the most frequent: chip of the insulator, bend of the pin, fracture of the pin, destruction of the insulator, separation of the insulator from the pin, distortion of the traverse, destruction of the traverse, bending of the traverse, decay or corrosion of the traverse.To increase the reliability of overhead power lines and reduce these damages, it is proposed to manufacture traverses from polymer composite electrical insulating material. Such traverses do not have insulators and are used as an electromechanical structure with the required mechanical and electrical strength.The objective of this work is to assess the mechanical strength of traverses made of polymer composite electrical insulating materials. To solve the set tasks, the work considers a three-dimensional model of the traverse. Its mechanical strength is determined using applied software implementing the finite element method (FEM). Loads in horizontal and vertical planes are applied to the cross-arm, the most stress-strained state of the traverse’s arms and the pin bracket is determined.In addition, the article compares the calculation results using the analytical method performed in the previous work with FEM calculation, verifies the assumed physical and geometric parameters, material properties and assumptions in calculations.
The Use of Electric Energy Storage Devices to Improve Traction Properties of Autonomous Locomotives

Published: December 2024

The analysis of international experience in development of autonomous locomotives with a hybrid power plant allowed to prove the possibility of increasing the operating efficiency of diesel locomotives using electric energy storage devices.A proposed circuit diagram of the power system of a diesel locomotive implies as source of energy both a diesel engine and a traction battery with a DC pulse chopper. An algorithm has been developed to control the traction drive of a diesel locomotive with a hybrid power plant, which ensures an increase in the tractive force of the locomotive on sections with difficult track profile. Modernisation of the power system of a diesel locomotive using a hybrid power plant is considered for the diesel locomotive of 2TE116 series. A mathematical model of operation of a diesel locomotive traction drive powered by a hybrid energy source through a controlled voltage breaker has been developed using the energy balance equations of a traction electric motor. Respective traction properties of 2TE116 diesel locomotive with a standard power plant and a hybrid power plant were calculated using numerical modelling methods in MatLab and LabView software environments. It is shown that, over the entire range of operation speed, a diesel locomotive with a hybrid power plant allows obtaining a tractive effort 15 % higher than a diesel locomotive with a standard power plant. Calculations have proved that increasing the traction properties of the modernised 2TE116 diesel locomotive makes it possible to increase the designated weight of the train by 15 %, and, accordingly, the efficiency of using the locomotive as a traction unit on the railway network.

Published: December 2024

The article discusses the problem of the relationship between Helicobacter pylori and the occurrence of B12 deficiency anemia (B12 DA). Chronic H. pylori infection is the main cause of gastrointestinal pathology in adults. H. pylori is microorganism that plays a role in vitamin B12 deficiency, causing gastric atrophy.
Objective — to establish the frequency of H. pylori contamination in patients with vitamin B12‑DA, to clarify and explain the probable connection between helicobacteriosis and the occurrence of B12‑DA.
Materials and methods. Literature data for the last 5 years were analysed, and a retrospective analysis of 100 medical records of inpatients treated for B12DA in the haematology department of the Chernivtsi Emergency Hospital in 2022—2023 was performed. The control group consisted of 30 practically healthy individuals.
Results. Among patients with moderate and severe B12DA, H. pylori contamination was detected in 85.5% of cases, which is significantly higher than in practically healthy individuals (odds ratio (OR) — 5.33 (95% confidence interval (CI) 2.49—11.44), p <0.05). H. pylori contamination was recorded in 79.7% of patients with moderate B12DA and 91.7% of patients with severe B12DA. In severe B12DA, the incidence of H. pylori contamination was 1.2 times higher than in moderate severity (OR 1.15 (95% CI 0.63—2.09), p >0.05). In patients with B12DA with a positive test result for H. pylori, chronic non‑atrophic gastritis was recorded in 32.9% of cases, atrophic gastritis — in 62.4%, normal gastric mucosa (GM) — in 4.7% (p <0.05), which significantly differed from the structure of pathological changes in the GM in patients with B12DA with a negative test result for H. pylori — 13.93, 26.7 and 60.0%, respectively (p <0.05).
Conclusions. Thus, a significantly lower frequency of normal histological structure of gastric mucosa was found in patients with B12‑DA with H. pylori contamination (OR=12.75 (95% CI 3.48—46.76)) versus H. pylori‑negative states (p <0.05).
