Gunung Ijen di Banyuwangi merupakan salah satu gunung aktif di Indonesia dengan ketinggian 2443 mdpl. Gunung ijen terkenal dikalangan wisatawan domestik maupun luar negeri karena fenomena alam api biru dan penambang belerang tradisional. Permasalahan utama adalah munculnya gas beracun secara mendadak. Gas beracun yang muncul dari kawah dalam konsentrasi tinggi sangat berbahaya. Berdasarkan keterangan dari Kepala Pos Pengamatan Gunung Api (PPGA) Ijen, gas beracun gunung ijen telah menelankorban  sekitar 70 orang sampai tahun 2013. Kondisi wilayah kawah terjal, berbatu, licin, curam dengan kemiringan hingga 450, sehingga diperlukan sistem peringatan dini (Early Warning System) untuk mendeteksi kandungan gas beracun konsentrasi tinggi melalui perangkat sensor. Perangkat sensor yang digunakan sesuai kondisi geografis dari kawah ijen yaitu mudah dalam penempatan, dapat dipindah sesuai kebutuhan keadaan dan mampu saling komunikasi dengan perangkat sensor yang lain termasuk berkomunikasi dengan server melalui jaringan sensor nirkabel (Wireless Sensor Network). Sistem komunikasi antar sensor node menggunakan singlehop. Daya jangkau perangkat zigbee sampai 200 meter tanpa halangan.  Tingkat efisiensi konsumsi arus listrik maksimal 35 mA dibutuhkan untuk mengirim data gas beracun CO dan H2S dari sensor MQ-9 dan MQ-136. Peringatan dini munculnya gas beracun dapat dideteksi dengan baik maka timbulnya korban jiwa dapat berkurang

Transformator didesain untuk bekerja pada frekuensi kerja tertentu. Penentuan frekuensi kerja transformator berkaitan dengan penentuan tegangan kerja, jumlah lilitan pada belitan transformator dan ukuran inti. Effisiensi dan regulasi tegangan merupakan watak transformator yang perlu diketahui dalam kaitannya dengan penerapan transformator dalam sistem tenaga listrik.

Penelitian dilakukan dengan mengoperasikan transformator 50 Hz pada beberapa frekuensi tertentu yaitu 30 Hz, 40 Hz, 50 Hz, 60 Hz, 70 Hz, 80 Hz, 90 Hz dan 100 Hz. Sumber listrik yang frekuensinya dapat diatur diperoleh dengan mengatur putaran generator sinkron. Pengaturan putaran dilakukan dengan mengatur putaran motor arus searah sebagai penggerak generator. Tegangan, arus dan faktor daya disisi primer dan sekunder transformator diukur dan digunakan untuk menghitung effisiensi dan regulasi tegangan. Effisiensi dan regulasi tegangan untuk masing-masing frekuensi diperbandingkan.

Data hasil penelitian memperlihatkan bahwa frekuensi mempengaruhi effisiensi transformator. Effisiensi transformator menjadi lebih rendah apabila transformator dioperasikan bukan pada frekuensi kerjanya. Pengaruh frekuensi terhadap effisiensi transformator terlihat jelas apabila transformator berbeban ringan. Regulasi tegangan transformator dipengaruhi frekuensi. Regulasi tegangan transformator menjadi lebih besar apabila transformator dioperasikan bukan pada frekuensi kerjanya.

The Sigmodontinae is a highly diverse subfamily of rodents that represents almost 30% of the mammalian species present in northwestern Argentina. However, the distribution of several species is delimited on the basis of scarce records. We add new localities for four poorly known species of rodents (Abrothrix andina Philippi 1858, Abrothrix jelskii Thomas 1824, Neotomys ebriosus Thomas 1894, Auliscomys sublimis Thomas 1900) in the High Andes of Jujuy and Salta provinces. We duplicate the number of known localities for A. jelskii in Salta, including the lowest known elevation record in Argentina and added the second known locality for Jujuy province. Furthermore, we add four new localities for A. sublimis, including the westernmost locality in Argentina, and reported for the first time this species at a departmental political division in NWA. Finally, we report the first departmental record for both A. andina and N. ebriosus in Valle Grande.
Research of frogs point wear resistance in various conditions for transportation systems: main-line railway and subway
Authors: Soroka O.
Published: July 2023

The experience of operating switches shows that load-bearing elements fail for two main reasons: defects and wear. The percentage failure of elements due to one reason or another depends on the operating conditions in which they operate. In this case, the most worn elements of switches are pointers and point frogs and their service life is determined by the amount of tonnage passed through them before reaching the standard values of wear or the appearance defects. The article is devoted to the study of wear resistance of switches operated in various transport systems, namely, mainline transport and subways. The article considers the issues of predicting the standard service life cross elements of typical angles using operational studies for subway conditions and a new theoretical methodology based on the analysis of switches withdrawn from operation after they reach the standard wear values for mainline transport. For analytical calculations, the method of modeling the interaction process and graph-analytical methods were used. As a result of the study, the analytical equations predictive curves for the formation vertical wear as a function of the passed tonnage for the switches point frogs operated on lines of mainline railway transport and the Kyiv subway were established.

This indicates the need to predict the development of the environmental situation in order to inform the population about possible disasters for preparing people's responses, resettlement planning, psychological adaptation. To predict the environmental situation as a result of accidents and disasters, including in rail transport, an analysis apparatus for possible situations is proposed with the aim of developing recommendations for their prevention. An environmental simulation model based on the theory of self-organization was chosen as the apparatus of research. It is based on the processes of mutually agreed relations, as a result of changes in two species of wildlife (object and environment), leading to the formation of a certain orderliness of these relations. Interaction of this kind occurs in the direction of achieving the existing equilibrium state or the formation of a new balance.
Models of criterion evaluation of the image processing systems effectiveness
Authors: Gertsiy O.
Published: July 2023

The criteria used to evaluate the effectiveness of image processing systems are investigated in the article. The requirements for performance criteria are analyzed. Private criteria which are used for image processing systems are selected and justified. Such parameters as performance, system cost, hardware costs characterize the system itself and depend on its specific type. It was shown that the information capacity, the probability of completing the task, and the accuracy of the image processing algorithm are the main criteria that characterize the quality of the processing method. It is shown that such a reliability criterion as normalized root mean square error best meets the requirements of efficiency criteria. Criteria models that are based on the normalized root mean square error in relation to discrete images have been studied. The simulation results and obtained dependences of cost functions on the speed of system information processing are given. The methodology for choosing a generalized criterion, which characterizes not only the information processing system, but also the methods used to implement this system was found. We obtained a generalized cost criterion, which arguments are the accuracy of system operation, speed of operation, and cost advantages.

Existing research concerning the extention of the service life of various types of railway vehicles and assessing its remaining lifetime has been reviewed and analyzed. It has been established that the vast majority of studies relate to the assessment of the residual lifetime of various types of railway rolling stock based on the results of technical diagnostics and routine tests, as well as the assessment of corrosion wear of supporting elements and vehicles bodies. At the same time, little attention has been paid to the issue of improving existing programs and procedures of complex technical diagnostics. It was determined that the set of diagnostics operations for the extension of the service life includes routine tests of a test sample and examination of the technical condition of the metal structure of each railway vehicle for mechanical and corrosive damage.It is proposed to make changes to the existing current programs and procedures in such key sections as: terminology, objects of technical diagnostics and tests, selection of a test sample for routine tests, execution order and methods of technical diagnostics and routine tests, data processing and evaluation of results. A comprehensive approach for assessing the residual lifetime of railway vehicles is also proposed.

The article examines the issue of the chassis system of a high-speed electric train with body inclination and a vibration recovery system. The advantages of using an electromechanical shock absorber over hydraulic, pneumatic and similar systems are described. The authors considered the main characteristics of the DC electromechanical shock absorber. The main overall parameters of the shock absorber were presented. Attention is paid to the relevance of using an electromechanical shock absorber of a linear type, in comparison with analogues, including the ability to recover energy. Attention is drawn to the structure of the DC electromechanical shock absorber. The functional control scheme of the electromechanical shock absorber is considered and the control algorithm is described. The calculation areas of the parameters of the electromechanical shock absorber are determined. A 3D model of an electromechanical shock absorber in the Ansys Electronics software environment is presented. A finite-element mesh was built for further calculations of the magnetic field and inductance. In the article, attention is paid to the calculation of the magnetic field in the most intense mode. A picture of the shock absorber's magnetic field at the maximum working clearance was obtained and interim results were discussed. The results of calculating the inductance depending on the operating gap of the shock absorber are presented. Conclusions were made based on the results of calculations of magnetic and electrical parameters of an electromechanical shock absorber based on a linear direct current motor.

The authors determined the intensity of the increase in wear of various elements of the body. It has been established that the lower trim, the roof slope and the lower part of the side wall have the greatest wear. It is proposed to use aluminum alloys for the modernization of passenger car bodies. The advantage of such a technical solution is an increase in the corrosion resistance of the body. The reduction of tare allows to reduce the specific resistance to train movement, reduce fuel and electricity costs for train traction. To reduce operating costs using the basic provisions of the locomotive traction theory, calculations were made to determine the energy consumption for the movement of a passenger train according to the profile conditions of the real section of the regional branch of the Southern Railway by diesel and electric locomotive traction with the base variant and the variant of passenger cars with reduced tare weight) in composition of the train. It has been established that the annual savings in energy costs for the traction of passenger trains when using passenger cars with a reduced tare weight is about 1 million UAH.

Education is a process of interaction and communication among all participants, in which each of them has an impact on the outcome. Today, in the conditions of the modern world, cooperation between the teacher and the student acquires new forms and characteristics. The teacher is no longer just a source of knowledge but becomes a partner and helper for the student. The quality of communication between the student and the teacher depends on their readiness for dialogue and mutual understanding, absence of coercion and orders. A comprehensive approach to education and communication allows for a deep understanding of the processes and their improvement. Higher education institutions need to pay special attention to issues of strategic communication development, branding, and image. Clear and well-planned communication systems should be implemented at the level of structural units in order to achieve success. Providing adequate material and technical resources as well as information and communication technologies is crucial for effective use of various teaching methods and forms. However, communication between a teacher and a student should not only be about academic topics, but also about support, motivation, and personal development.
