The work is devoted to the study of the electric pulse disintegration of a natural mineral. The object of the study is the natural mineral quartzite of the Aktas deposit of the Republic of Kazakhstan.
For the destruction and grinding of quartzite, a working cell of an electric pulse unit was developed. Electric pulse crushing is a modern technique for grinding a variety of materials, which provides the desired degree of grinding with a certain granulometric composition of the product and has a high ability of selective crushing. With the help of this technology, quartzite grinding was carried out with an increase in the capacity of capacitor banks from 0.25 mF to 1 mF, the pulse discharge voltage changed from 20 kV to 30 kV, the number of pulse discharges from 500 to 1,000, the inner diameter of the working cell from 60 mm to 80 mm. The results of the disintegration of a natural mineral by the electric pulse method allowed us to determine the degree of grinding of the finished product.
The obtained results can be used in the study and optimization of the extraction of natural minerals, which is important for ensuring the sustainable use of natural resources and balanced economic development.
Crushed quartzite is used in various industries, including the production of optical fibers, electronics and photovoltaic devices. A material with a particle diameter of 0.1 to 0.4 millimeters is used to create glass, ceramic and porcelain products, as well as insulation materials. Due to its homogeneous composition containing up to 98 % silicon oxide (SiO2) and excellent absorbent properties, quartz sand is also used as a filter material for water purification

Published: March 2024

This study presents the neutronic design of a small modular long­life Pressurized Water Reactor (PWR) using thorium carbide fuel with 233U fissile material. The target optimization for this study is a reactor designed to operate for 20 years, with excess reacti­vity throughout the reactor operational cycle consistently below 1.00 % dk/k. The analysis involves dividing the reactor core into three fuel regions with 233U enrichment levels ranging from 3 % to 8 %, with a 1 % difference for each fuel region. To achieve optimum conditions, 231Pa was randomly added to the fuel. The fuel volume fraction in this design varied from 30 % to 65 %, with a 5 % incremental variation. Power level variations are also studied within the 300–500 MWth with increments of 50 MWth. Calculations were performed using the Standard Reactor Analysis Code (SRAC) program with the PIJ and CITATION modules for cell and core calculations utilizing JENDL­4.0 nuclide data. Neutronic calculations indicate that the fuel with a 60 % volume fraction achieves optimum conditions at a power level of 300 MWth. The best performance was observed with a fuel volume fraction of 65 %, reaching optimum conditions across power levels ranging from 300 to 500 MWth. For the fuel with the best performance, the power density distributions for low and high power levels follow the same pattern radially and axially. The power peaking factor (PPF) for all fuel configurations approaching the optimum conditions remains below two, a safe limit for the PWR. Other neutronic safety parameters, such as the Doppler coefficient and void fraction coefficient, also stay within the safe limits for the PWR, with both values remaining negative throughout the reactor operational cycle

Authors: Chigirinsky Valeriy , Naizabekov Abdrakhman , Lezhnev Sergey , Naumenko Olena , Kuzmin Sergey
Published: March 2024

The plane problem of rolling theory is analytically solved using the method argument of functions of a complex variable. The solution to the plane problem has been strengthened from the point of view of the asymmetry of the process, which made it possible to consider the applied problem as the interaction of differently directed zones in the deformation zone. The interaction of lagging and advancing zones is represented as a combination of multidirectional processes in a single deformation zone. With a change in kinematic, power characteristics in local zones, the process parameters change in the entire deformation zone. Stressed states of intermediate loading schemes between stable and unstable rolling are considered. A feature of the interaction of zones with the opposite flow of metal is the analogy with the action of back tension on the deformation zone in literally all parameters - this is the presence of tensile stresses in the lagging zone, a decrease in local specific pressures, a shift in maximum normal stresses towards the exit from the rolls, a change in the length of the advance zone, reduction in rolling force.
The studies confirm and repeat the generally accepted provisions of the theory of rolling but reveal the effects of changes in the stress state under different loading models.
The results of the work make it possible to determine the modes of rolling processes visually and computationally under conditions of strong and weak interaction of zones with an oppositely directed metal flow.
The effects of plastic deformation with a decrease in the total effort in the processes that are within the reach of the limiting focus of crimping under conditions of increasing kinematic load when the gripping angles vary between 0,077…0,168 are given

Published: March 2024

The object of this research is the integrated processing of industrial waste from various industries, which makes it possible to reduce the use of material and energy resources and improve the ecological state of the environment. Waste from the chemical, petrochemical, and machine-building industries was subject to integrated technological processing.
The common link that united the investigated complex technological cycles was the use of a regenerated mixed sorbent (activated carbon+kieselguhr), on the surface of which topochemical transformations of chemicals that were part of industrial waste took place. Using a regenerated mixed sorbent, exhausted industrial oil which was the mineral basis of the developed new C, S, N-containing plastic lubricants was purified. In particular, we have established the conditions for obtaining diethyl ammonium chloride from unusable pesticides of the formula R1R2R3R4C6HCOOH∙HN(C2H5)2, whose topochemical interaction on the surface of the mixed sorbent leads to the formation of a sorbed fragment [sorbent (activated carbon+kieselguhr)]∙[(C2H5)2NC(=S)SK]. Subsequent interaction of aqueous solutions containing copper(II) ions with such a fragment leads to the formation of bis–(diethyldithiocarbamate)copper(II) on the surface of mixed sorbent. The resulting substances of the general composition [sorbent (activated carbon + kieselguhr)]∙{[(С2H5)2NC(=S)S]2Cu} were studied as thickeners and active polyfunctional components of the obtained plastic lubricants. Research into the tribological properties of new C, S, N-containing plastic lubricants showed their high anti-wear and heat-resistant properties and the possibility of effective use in highly loaded friction nodes

Published: March 2024

The Kalman filter algorithm is very important as a recursive algorithm method to optimize sensor output from physical parameter measurement systems, especially physics practicum demonstration systems. One of the distance parameter measurement demonstration systems used in Hooke’s law demonstration system is applied in physics practicum, the system has problems related to fluctuating or unstable sensor output. This research implements the Kalman filter algorithm on the Arduino IDE sketch to reduce noise that appears at the ultrasonic sensor output. The methodology used in this study includes the application of the Kalman filter algorithm to the Arduino IDE sketch with the variable value of the Kalman filter algorithm equation modified with a value of R=10, H=1, and Q=1, and returns the filtered Kalman out value. The Arduino output results are exported to Ms. Excel for further analysis and generate a filtered ultrasonic sensor output signal graph compared without using the Kalman filter. The ultrasonic sensor output noise filtration effectively reduces noise by showing a decrease in the mean squared error (MSE) value and obtaining the best performance of up to 89.23 %. The accuracy of Kalman filter filtration results can be seen from the calculation that the spring constant of filtered metal materials is smaller than the conventional measurement spring constant. Accurate and effective results with the implementation of the Kalman filter algorithm can be developed for the variation values of distance parameters and Kalman filter algorithm variables (R, Q, and H) with other value variations, especially variables that produce filtering curves close to straight lines. It was concluded that the Kalman filter algorithm was able to improve the performance of Hooke’s law prop system
Determining vertical oscillations of front-plow tractor without support wheel

Published: March 2024

The object of this study is a tractor with a front plow without a support wheel. One way to avoid the use of ballast is to use front-mounted plows that operate under the "push" mode. As a rule, such plows are equipped with at least one supporting wheel. The presence of the latter complicates the structure of the plow and, of course, affects the degree of vertical load on the steered wheels of the mobile vehicle.
With the help of the constructed mathematical model and the corresponding amplitude and phase frequency characteristics, the dynamics of vertical oscillations of the front axle of a tractor with a front mounted plow without a support wheel were investigated. Vertical fluctuations of the total force acting on the tractor from the side of the plow were considered as a disturbing influence. According to the simulation results, an increase in the vertical load of the front axle of the tractor by 600 kg causes a desired decrease in the value of the amplitude and an increase in the phase of external disturbances of the dynamic system. The higher the frequency of disturbance oscillations, the more acceptable these characteristics become. It was established that in order to improve the response of the studied dynamic system to disturbances, it is necessary to reduce the stiffness coefficient of the tires of the front wheels. In practice, this is achieved by adjusting the air pressure in the tires. The amplitude-frequency characteristics of the system almost do not change when the damping coefficient of the tires of the front wheels of the tractor is increased in the range from 1 to 3 kN·s/m, while the phase-frequency characteristics improve. This is especially noticeable at the frequencies of oscillations of the disturbing influence in the range of 0–10 s-1.
The results could be used as a basis for evaluating the efficiency of tractors with a front plow without a support wheel in tillage operations. Such efficiency can be achieved under the condition of practical implementation of the recommendations proposed in this paper regarding the selection of design parameters of tires for the front wheels of the tractor

Published: March 2024

This study aims to investigate the operation of a tractor as part of the tillage unit on the basis of analysis of its interaction with the supporting surface and the correlation between the mass of the tractor and tool. The classic approach to determining the efficiency factor does not take into account the extensive system of power take-off shafts and the extent of their use in combined tillage units. To solve the related problem, a mathematical apparatus was built in the study, which makes it possible to determine the rational ratio between the traction force of a tractor and the mass of the tillage unit.
Underlying the methodological basis of the work is the generalization and analysis of the study of traction indicators of the tractor as part of the tillage unit. Empirical models of unit operation were constructed by employing the basic principles of the system approach and analysis of technical systems. When improving the methodology of research using the method of partial accelerations and our devised procedures, it was possible to significantly reduce the time without compromising the quality of results. The maximum traction efficiency for John Deere 8R series tractors as part of the tillage unit was determined, ηTmax=0.719, as well as the conditions for its provision. The traction efficiency for tractors with wheel formula 4K2, mass Gim=6–10 t, with power consumption from 60 % to 80 % was determined; it is 0.58–0.64. The results of the study make it possible to obtain a new solution to the scientific problem of ensuring the maximum traction efficiency of the tractor as part of the tillage unit, based on the rational ratio between the traction force of the tractor and the weight of the machine-tractor unit. The proposed system approach could be used to justify the layout of units and recommendations regarding their modes of operation in the case of instability of operating mass and traction force

Published: March 2024

The object of this study is the growing interest of the target audience in the introduction of category management tools to the business processes of pharmacy retail. In pharmaceutical practice, the methodical toolkit for the study of the category management system is not sufficiently widely presented. That is why, using the theoretical and methodological basis and conceptual principles of product category management, the evaluation methodology of the MARS Category Management Profile was devised.
The purpose of the work is to introduce new approaches to the formation and management of the pharmacy assortment based on the concept of category management and to determine ways to increase the level of efficiency of its work.
As a result of the research, the quantitative value of the existing and optimal result of category management in the network of pharmacies was determined. The calculations show that in the current state the goal orientation is 36 points, and in the optimal state this characteristic will be equal to 27 points, while the analysis orientation is 21 and 28 points, respectively. It has been established that categorical management is focused precisely on the analysis and adherence to research tools, and not on the uncontrolled achievement of the goal.
The proposed organizational model of functional interaction of specialists in pharmacy retail could ensure the implementation of principles and the performance of complex tasks facing the category manager. The described components of the MARS category management profile will be used in practice to improve approaches to planning, information and analytical support, and control over the main management processes of the enterprise under study. This could avoid disagreements between management and medical specialists
Analytical description of adjustment of rolls for manufacturing parts from elastic sheet material
Authors: Pylypaka Serhii , Hropost Vyacheslav , Volina Tetiana , Kresan Tetiana , Borodai Serhii
Published: March 2024

The object of research is the process of bending sheet material, taking into account its springiness. When manufacturing sheet parts by bending from a completely elastic sheet, its shape is completely restored after the deformation stops, unlike an elastic sheet. Thus, when producing cylindrical parts by drawing between three rolls, the resulting radius of the cylindrical part will be larger than the calculated one. This phenomenon is evaluated by the coefficient of springing – the ratio of the calculated radius to the one obtained after partial expansion.
When manufacturing conical parts, this approach cannot be applied, because the value of the radius is variable. The article applies the theory of surface bending from differential geometry. The curvature of the line on the surface has two components - normal and geodesic. When the surface is bent, the normal component changes, while the geodesic component remains unchanged. The magnitude of the normal component depends on the angle between the origin of the cone and its axis. So, for a cone with a base of radius R and an angle of 20°, the normal curvature is 0.94/R, and the geodesic curvature is 0.34/R. For cylindrical parts, the geodesic curvature of the cross-section (circle) is zero, so it is not necessary to take it into account.
Usually, adjustment of rolls for the production of conical parts is carried out experimentally. The difference of the proposed approach lies in the elimination of this problem thanks to the decomposition of the curvature of the base of the cone into two components. This allows to calculate the settings of the rolls and thereby reduce their adjustment time. The parameters of the rolls and their mutual placement are calculated for the production of conical parts of the required size, taking into account their springiness. The field of application of the obtained results is the production of parts by bending flat metal sheet blanks
Construction of homogeneous solutions of the torsion problem for a radially inhomogeneous transversely isotropic cylinder
Authors: Akhmedov Natiq
Published: March 2024

The torsion problem for a radially inhomogeneous transversely isotropic cylinder of small thickness was investigated by the method of asymptotic integration of elasticity theory equations. It is assumed that the side part of the cylinder is stress-free, and boundary conditions are set at the ends of the cylinder, leaving the cylinder in equilibrium. The elastic moduli are thought to be arbitrary continuous functions of the variable along the cylinder radius. The formulated boundary value problem is reduced to a spectral problem containing a small parameter characterizing the thin-walledness of the cylinder. Homogeneous solutions are built, i.e. any solutions of the equilibrium equation satisfying the condition of no stresses on the side surfaces. It is shown that the solution of the torsion problem consists of a penetrating solution and a boundary layer character solution similar to Saint-Venant's edge effect in the theory of inhomogeneous plates. The penetrating solution determines the internal stress-strain state of a radially inhomogeneous cylinder. The stress state determined by the penetrating solution is equivalent to the torsional moments of stresses acting in the cross-section perpendicular to the cylinder axis. Solutions having the boundary layer character are localized at the ends of the cylinder and decrease exponentially with distance from the ends. These solutions are absent in applied shell theories. Asymptotic formulas for displacement and stresses are built, which make it possible to calculate the three-dimensional stress-strain state of a radially inhomogeneous transversely isotropic cylinder of small thickness. Based on the obtained asymptotic expansions, it is possible to assess the applicability of applied theories and build a refined applied theory for radially inhomogeneous cylindrical shells

Published: March 2024

The object of this study is to robotize the technological operation of removing the oxide film from the surface of a magnesium melt poured into continuously moving molds of a casting conveyor for the production of commercial magnesium. To robotize this technological operation, it is proposed to use a two-armed manipulation robot with a spherical coordinate system, which has six degrees of mobility. Software trajectories have been developed according to the degrees of mobility of the manipulation robot in terms of position, speed, and acceleration to perform the technological operation of removing the oxide film from the surface of the magnesium melt poured into the moving molds of the foundry conveyor. Programmed trajectories are described by quadratic polynomials that satisfy restrictions on the values of the generalized coordinate, velocity, and acceleration. These limitations are determined by the design features and energy capabilities of the degrees of mobility drives of the manipulation robot. Programmed trajectories along the first and second degrees of freedom compensate for the continuous movement of the molds of the foundry conveyor. Programmed trajectories along the third and fourth degrees of mobility enable the collection of the oxide film from the surface of the magnesium melt. Programmed trajectories along the fifth and sixth degrees of freedom enable the discharge of the collected oxide film into a special container. The reliability of the developed programmed trajectories is confirmed by the simulation results using MATLAB version R2015b. Based on the results, a cyclogram for controlling a manipulation robot has been constructed to perform the technological operation of removing the oxide film in the production of commercial magnesium. The results could be used in the robotization of technological processes for removing the oxide film in the production of commercial magnesium or similar foundries

There is a need for an effective monitoring solution for water quality control in tailings dumps and adjacent water bodies in order to prevent environmental pollution. This article highlights the importance of water quality monitoring and surveillance to prevent pollution. It is proposed to develop a mobile robotic complex equipped with sensors for monitoring water bodies and tailings, which is also capable of measuring underwater topographic data. The objects of study were a tailings pond and water bodies.
The authors analyzed existing technical monitoring solutions, designed and developed a robotic complex, echolocation device, tested them on specific sites (the tailings dump of the Zhayrem Mining and Processing Plant and the Ishim River), conducted laboratory analysis of water samples, classified the results. Additionally, they obtained 2D and 3D maps of the bottom, and entered all collected data into a developed database and software.
The developed complex demonstrated high accuracy of movement (an error of about 0.2 m on the x axis and 0.1 m on the y axis) and the ability to register environmental parameters such as temperature, humidity, PH. Data analysis for 2021–2023 showed a significant excess of recycled water discharged into the evaporator pond, which emphasizes the importance of monitoring and management of water resources.
The research applies ARIMA models, neural networks to predict water body parameters. The results obtained indicate the high efficiency of the developed robotic complex and methods for analyzing data on water resources. These methods can be used in industry, scientific research and environmental projects to regularly monitor water quality and take measures to protect it

Published: March 2024

Introducción: El presente estudio revisa los postulados sobre la contribución de las relaciones infantiles de apego en el establecimiento de relaciones en la adultez. El objetivo fue explorar la asociación entre la percepción de los vínculos primarios establecidos con las figuras parentales y los estilos de apego adulto en jóvenes universitarios.
Método: Se realizó una investigación no experimental, cuantitativa, exploratoria y transversal. Participaron 247 estudiantes universitarios de Quito, 41,6 % de sexo masculino y 58,4 % de sexo femenino, entre 18 y 25 años de edad (M=20,75; DE=2,04). Se emplearon dos instrumentos validados en el Ecuador: la escala Parental Bonding Instrument (PBI) en sus versiones Madre y Padre y la escala Experiences in Close Relationships-Revised (ECR-R).
Resultados: Entre el ECR-R y el PBI se registraron correlaciones significativas únicamente en la versiónMadre: una inversa entre cuidado y evitación (r = -0,226; p < 0,001) y otra directa de sobreprotección con ansiedad (r = 0,203; p < 0,001) y con evitación (r = 0,147; p < 0,05). Se halló que la percepción del vínculo con las figuras parentales, especialmente con la madre, se asocia con los estilos de apego adulto (madre: r = 0,224, p < 0,001; padre: r = 0,136, p < 0,033).
Conclusión: El cuidado infantil contribuye al  establecimiento de relaciones saludables en la adultez,no así la sobreprotección. La madre tiene un rol  rotagónico en este aspecto, posiblemente debido a factores socio-culturales, por lo que es importante que la figura paterna asuma un rol más participativo.

During the operation of the gas pipeline system of the Russian Federation, a significant share of natural gas is consumed for the own needs of compressor stations of main gas pipelines.According to Gazprom's reporting, the share of natural gas for technological and fuel needs reaches 7 % of the production volume. The inefficient use of natural gas can be reduced by energy saving measures implementation.Energy saving issues are important not only for Gazprom PJSC, but also for the country's economy as a whole. The highest priority of the «Energy Strategy of Russia for the Period up to 2035» and «The Concept of Energy Saving and Energy Efficiency Improvement of Gazprom PJSC» is the maximal realization of all available energy saving potential.Saving of energy resources can be achieved by organization of their efficient con-sumption, the use of innovative energy-saving technologies and equipment, reduction of losses and gas consumption for the own needs of compressor stations.The article presents the results of the analysis of the parameters of natural gas pumping through the Chelyabinsk – Petrovsk main gas pipeline on the 112–292 km section operated by Gazprom Transgaz Ufa LLC.It has been established that the monthly unevenness of the gas supply through the gas pipeline under consideration varies from 0.062 to 0.195. As a result, in many modes, the compressor station, regardless of any possible schemes for switching on gas pumping units, does not allow the planned gas pumping mode to be ensured without bypassing part of the gas through the recirculation circuit of the station.One of the solutions to this problem is the installation of a recirculating valve, which allows to provide the required volume of gas flow through the recirculation line, while providing an economical mode of operation of the compressor station.
Plugins and POPI: A Critical Discussion into the Legal Implications of Social Plugins and the Protection of Personal Information
Authors: Schultz Helga , Freedman Warren
Published: March 2024

Social plugins are one of the many trackers used by companies with an online presence. However, under the Protection of Personal Information Act 4 of 2013 (POPI), these trackers have certain legal consequences for internet users. The main reason for this is that trackers tend to process personal information without informing internet users that their data are being collected, the reason for the collection or processing thereof, or who the responsible parties are that are collecting and processing the personal information. The article looks at these issues, amongst others, in the light of a 2019 judgment from the Court of Justice of the European Union or CJEU, namely, Case C-40/17 Fashion ID GmbH & Co. KG v Verbraucherzentrale NRW e.V. EU:C:2019:629. Due to the fact that it has had data protection legislation for much longer than other countries or legal jurisdictions, including South Africa, the European Union (the EU) has a substantial body of case law interpreting the data protection legislation of the EU itself as well as that of the individual member states. One of the main instruments used as guidance by the drafters of POPI was Directive 95/46/EC of the European Parliament and of the Council of 24 October 1995 on the Protection of Individuals with Regard to the Processing of Personal Data and on the Free Movement of Such Data (hereafter Directive 95/46). Directive 95/46 was previously considered the gold standard, before Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the Protection of Natural Persons with Regard to the Processing of Personal Data and on the Free Movement of Such Data (General Data Protection Regulation) (hereafter the GDPR) was enacted and Directive 95/46/EC was finally repealed. Since Directive 95/46 was one of the main guiding documents used in drafting POPI, one may expect that the South African courts may turn to the EU and consider how the CJEU has interpreted the similar provisions contained in Directive 95/46, especially since there is very little South African jurisprudence available on POPI. The four main issues under discussion are: who, other than the internet users, has the locus standi to bring an application in terms of POPI? Second, what are the responsibilities of joint responsible parties towards internet users? Third, where there are joint responsible parties, do both need a legitimate interest to process personal information? Lastly, who will be responsible for obtaining the necessary consent to process the personal data?
Zimbabwe's coloured gemstone endowments - A regional geological overview
Authors: Mamuse A. , von der Heyden B.P. , Blenkinsop T.
Published: March 2024

Zimbabwe hosts a varied array of coloured gemstones. With the exception of emerald deposits and several world-class pegmatites, few of the gemstone occurrences have received detailed attention from the scientific or mineral exploration communities. In the present contribution we summarize the status of knowledge of the gemstone deposits and occurrences in Zimbabwe, paying particular attention to the geological settings in which they were formed. Synthesis of this regional geological approach reveals that there may be significant exploration potential for further gemstone occurrences, particularly in the extensive pegmatite fields and in Al-enriched orogenic belts that have undergone greenschist to granulite facies metamorphism. Further socio-economic and developmental initiatives will aid in optimizing the value generation from this important sub-sector.

Authors: Шаровара Кристина Артемовна
Published: March 2024

Целью исследования является сравнительный анализ существующих теоретико-методологических подходов и парадигм социально-философского изучения ценностей как основы цивилизационного своеобразия обществ и в частности России.

Методологическую базу исследования составляют методы сравнительного анализа и метаметодологической рефлексии.

Результаты исследования. В условиях усложнения мировой обстановки и роста международной напряженности актуальным становится анализ особенностей и специфических характеристик цивилизаций. В свете этого большое значение приобретает поиск методологии, ориентированной на понимание цивилизационных различий в мировом пространстве. Обычно предпочтительным является обращение к цивилизационному подходу. Речь идет о необходимости цивилизационной рефлексии и укрепления национальной цивилизационной идентичности, что становится актуальным вызовом для общества. В построении основы цивилизации важную роль играют сакральные ценности, формирующие коллективную ментальность. Анализ цивилизационно-культурных ценностей в настоящее время требует использования широкого спектра теоретических подходов и парадигм, взаимодействующих для решения разнообразных исследовательских задач. Среди выделяемых автором наиболее значимых подходов и парадигм отмечается цивилизационный подход, дающий возможность исследования объективных факторов, таких как природные особенности, климатические условия, этногенез и другие предпосылки исторического развития цивилизационных особенностей: аксиологический подход, основывающийся на выделении и анализе базовых сакральных ценностей, принадлежащих культурному ядру цивилизации; социокультурный подход, ориентирующий на рассмотрение базовых ценностей цивилизации в контексте социокультурной динамики, глобального влияния и процесса глобализации в контексте анализа социокультурной триады, объединяющей социальные и культурные аспекты общества; подход, основанный на конструктивистской парадигме, для исследования процессов формирования и направленного конструирования цивилизационной идентичности как субъективного элемента цивилизации. Элементы различных подходов, несмотря на их различия, оказываются совместимыми и необходимы в силу сложности цивилизационной проблематики, которая не поддается редукции.

An labeling of a graph  is a function f from the set of vertex V(G) to the set of positive integers for any two vertices u, v where label difference |f(u)-f(v)|≥3 for distance d(u,v)=1 and label difference |f(u)-f(v)|≥1 for distance d(u,v)=2. In this study, the smallest positive integer λ where the maximum label used on L(3,1)-labeling for supercycle graph Sc(n,r) was formulated. The supercycle graph Sc(n,r) is the result of combining two special graphs, namely cycle graph  Cn and Hanoi graph Hr. To determine the formula for the minimum span value of labeling on supercycle graph, a pattern detection method is used, which is labeling several supercycle graph with certain n and r values, then we generalized. We obtained that λ(Sc(n,1))=6 if n= 1. Furthermore, λ(Sc(n,1))=7 if n1 and even; λ(Sc(n,1))=8 if n1 and odd. In addition, λ(Sc(n,r))=8, for r1.Keywords: L(3,1)-Labeling, Supercycle Graphs. AbstrakPelabelan L(3,1) didefinisikan sebagai pemetaan dari himpunan titik pada graf G ke himpunan bilangan bulat positif dimana untuk setiap dua titik u,v jika d(u,v)=1 berlaku |f(u)-f(v)|≥3 dan jika d(u,v)=2 berlaku |f(u)-f(v)|≥1. Pada penelitian ini dirumuskan nilai minimal rentang (span) pelabelan L(3,1) untuk graf supercycle Sc(n,r), yang dinotasikan dengan λ(Sc(n,r)). Graf supercycle Sc(n,r) merupakan hasil dari penggabungan dua buah graf khusus, yaitu graf cycle Cn  dan graf Hanoi Hr.  Proses penentuan nilai minimal span dari pelabelan L(3,1) pada graf supercycle, digunakan metode pendeteksian pola, yaitu dilakukan pelabelan pada beberapa graf supercycle Sc(n,r) dengan nilai n dan r tertentu, kemudian digeneralisasi secara induksi. Hasil penelitian ini diperoleh nilai  λ(Sc(n,1))=6, jika n=1. Kemudian, λ(Sc(n,1))=7, jika n1 dan n genap, λ(Sc(n,1))=8, jika n1 dan n ganjil. Selanjutnya, λ(Sc(n,r))=8 untuk r1.

Passo Village is a lowland area, where the Passo area has quite dense residential areas. . The increase in population growth and changes in land use that occur in the Passo Village area have resulted in many changes that will have negative impacts in the form of flooding or inundation. This is what happens in the Passo Village area, where during the high intensity rainy season there are often floods or puddles around the area. The existing canal system is not functioning properly. This is due to the narrowing of the Passo Canal channel due to the presence of buildings on the canal border such as residences and shops. The Passo Canal was used as a rubbish dump. The dimensions of the canal have changed and cannot accommodate the existing hydrological discharge. In overcoming this problem, the aim of this research is to determine the water level in the Passo Canal with the help of HEC-RAS 5.03 Software and to find out preventive methods for overcoming flooding problems in the Passo Canal. The initial stage is hydrological and hydraulic analysis. The results of the hydrological analysis are rainfall distribution using the Log Pearson III distribution, to calculate the planned discharge using the Der Weduwen method, it is obtained with a 10 year return period of 0.398 m3/sec. The results of hydraulic analysis using HEC-RAS 5.03 software showed that the highest water level at the S15 canal section was 0.52 meter. From this research it can be concluded that the Passo Canal requires flood management efforts, especially by normalizing the canal cross-section.
The Need to Develop Open Source Software Ecosystem: Library Professional’s Perspective

Published: March 2024

To stay ahead in the competition and to hold users to themselves, proprietary software and hardware vendors develop their closed ecosystems. Seamless interconnection of devices and easy inter-operability are thus implemented for a closed circle of users and provide a niggle free experience in using applications across devices and offer seamless data transfer across devices and applications. Microsoft, Apple, and Google are integrating this strategy on all their devices and products. It is the need of the hour, for open-source software proponents and developers to rise to the occasion to combat the monopolistic tendencies that hinder openness. Library professionals who have either adopted Open-Source Software (OSS) or information professionals who are on the verge of moving in the direction of OSS need to consider investing time, effort, and resources in developing and sustaining a counter movement with an alternate OSS ecosystem.
