Desain dan Simulasi Battery Charger Metode CC-CV (Constant Current-Constant Voltage) dengan Kontrol Logika Fuzzy Menggunakan MATLAB
Authors: Rahmatullah Faris
Published: August 2021

Baterai merupakan salah satu sistem penyimpanan energi listrik. Namun, dalam pengisiannya rentan mengalami kerusakan. Kerusakan pada baterai sering terjadi ketika dilakukan pengisian daya yang berlebih (over charging). Waktu pengisian baterai juga menjadi faktor yang perlu diperhatikan dalam pengisian daya. Oleh karena itu, pengisian daya baterai yang efisien menjadi penting dan sangat perlu dilakukan untuk menghindari terjadinya kerusakan. Sistem charging pada baterai disini dengan metode constant current-constant voltage (CC-CV) menggunakan dua buah kontrol logika fuzzy. Metode charging CC-CV digunakan untuk memaksimalkan daya charging dengan waktu yang singkat serta mencegah terjadinya over charging pada baterai. Kontrol logika fuzzy pertama dan kedua digunakan untuk mengatur duty cycle agar arus konstan dan tegangan konstan. Dari hasil simulasi menggunakan metode CC-CV ketika kondisi CC diperoleh nilai arus sebesar 3.3A pada duty cycle 42.6% dan terjadi transisi menuju kondisi CV ketika state of charge (SoC) 80.02% dengan nilai tegangan sebesar 14.4 V pada duty cycle 41.2%. Pengisian daya dan peningkatan SoC pada metode CC-CV lebih cepat 0.15 detik terhadap metode CC dan 0.25 detik terhadap metode CV.

Using hot uniaxial pressing in an argon atmosphere with a stress of 35 MPa and with a holding at 800 °C for 1 hour, ceramic composites of Bi3Ru3O11 – 50, 65 wt % Bi1,6Er0,4O3 were obtained. It was found that phase composition of the composites does not change during gas chromatographic testing at 800 °C and well corresponds to the specified one. Microstructure of the obtained composites was tested and the formation of dense composites with a total porosity of less than 1% and with a uniform distribution of the Bi3Ru3O11 and Bi1,6Er0,4O3 components in bulk of material was demonstrated. Transport properties (total conductivity, oxygen fluxes and selectivity of separating oxygen over nitrogen) of the obtained composites at 600 – 800 °C had been investigated. Thus, at 800 °C the electrical conductivity of Bi3Ru3O11 – 50, 65 wt % Bi1,6Er0,4O3 was about 200 and 50 Ohm–1∙cm–1, respectively, while the metallic nature of their temperature dependence of conductivity is correlated to that for the Bi3Ru3O11. The value of oxygen permeability for the obtained ceramic composites of about 7∙10–9 mol·cm–1·s–1 at 800 °C, which is compared to other membrane materials based on bismuth oxide, demonstrated the potential of their further use in the tasks for obtaining of pure oxygen from air.

Diffusion-thermal phase transformations in a modified titanium hydride containing a multiparting system of hydrogen traps. Modification of titanium hydride was carried out by the method of layer-by-layer electrochemical precipitation of metallic titanium and copper from organic and inorganic solutions of their salts. The creation on the surface of the titanium hydride of a multilayer coating (Ti – Cu) obtained by the electrochemical precipitation method increases the thermal stability of the metal hydride system by 229.7 °C. Methods of X-ray-phase, X-ray structural and electron-probe microanalysis are shown, the constancy of the phase composition of the modified titanium hydride in the temperature range of 100 – 700 °C. The most essential defects of the crystal lattice in a modified titanium hydride occur at a temperature of 500 °C — due to the hydrogenation of the modification titanium shell and blocking the microcrack of the surface with a copper coating, the period of the elementary cell and the volume of the hydride phase crystal volume changes. The largest concentration of hydrogen in the surface layer (up to 87.9 %) occurs in the temperature range of 300 – 500 °C, which ensures the maximum density of defects in the crystal lattice. At 700 °C, a dislocation density decreases and a decrease in the crystal cell parameters associated with the annealing mode of titanium hydride and hydrogen thermal diffusion into the volume of material. A metallic titanium precipitated on the titanium hydride surface is an effective structural trap of hydrogen diffusing to surface layers during thermal heating, and the creation of an additional protective copper sheath prevents the thermal diffusion of hydrogen into the environment.

A hybrid composite material fabricated from the Al – Nb system using severe plastic deformation by high-pressure torsion (HPT) up to 30 turns has been studied in the present work. To fabricate the composite, deformation of a three-layer Al – Nb – Al package was carried out at room temperature on Bridgman anvils with grooves under a pressure of 5 GPa at N = 10, 25 and 30 revolutions, at a strain rate of ω = 1 and 2 rpm. Initial disc diameters from pure metals and HPT conditions were experimentally optimized to obtain monolithic and defect-free composite samples. The most intensive fragmentation and stirring of niobium in the aluminium matrix was observed if diameter of aluminium discs was 10 mm and deformation conditions N = 25 and 30 revolutions and ω = 2 rpm were applied. Three microstructural zones were observed after HPT under optimal conditions: the central zone with wide curved layers of niobium in aluminium, the mid-radius zone with finely dispersed layered structure, and periphery with a uniform distribution of niobium in the aluminium matrix. It was shown that HPT led to formation of the intermetallic Al3Nb phase. The microhardness measured along the diameter of the obtained composite materials changed nonmonotonically depending on the produced structure (microstructural zone).

The paper presents a study of welded joints of cast intermetallic single-crystal rhenium containing VKNA-25 alloy with crystallographic orientation [001] and deformable high-temperature disk nickel alloy EP975, depending on the parameters (temperature and degree of deformation) of pressure welding under superplasticity conditions. Comparison of samples before and after heat treatment is presented. The results of X-ray micro-spectral analysis of a solid-phase joint in the welding zone and at distances of up to 140 μm are presented in comparison with the initial chemical composition of the alloys, indicating an intense course of diffusion processes. The results obtained are analyzed from the point of view of maintaining the balance of alloying, calculated by the method of G.I. Morozova (calculating the number of valence electrons per unit atomic mass of the composition), the change in the atomic mass and average electron concentration of solid-phase compounds before and after heat treatment in the welded joint zone and at distances up to 140 μm was calculated. It is shown that the alloy compositions calculated taking into account the alloying balance make it possible to obtain a high-quality one-piece connection of a disk and a blade for blisk-type structures, performed under superplasticity on an installation for high-temperature pressure welding.

Published: August 2021

Thermally hardened alloys based on iron (50 Cr – V – N type steel), titanium (VT-14), and aluminum (D16) were subjected to deformation by gas extrusion with local heating in the mode of deformation-thermal hardening with high degrees of deformation 90 % or more to obtain a thin wire at the output. Gas extrusion was performed at various combinations of processing parameters — gas pressure, deformation temperature, extrusion speed. The wire deformed under various combinations of processing parameters was cooled in air, subjected to tempering or aging and a tear test. The mechanical properties obtained as a result of the tests were compared with the data on the mechanical properties of the initial, undeformed alloys, heat-treated and non-heat-treated. On all gas-extruded alloys, the mechanical properties exceeded the initial ones both in strength and plasticity. The combination of gas extrusion parameters (gas pressure, deformation temperature, extrusion speed) has a decisive influence on the combination of strength and ductility of alloys treated by gas extrusion.

Disposal latex and synthetic rubber gloves is troublesome such that disposal via incineration and land fill may release poisonous gasses and contaminate soil and water, respectively. As solution to latex and synthetic rubber, biodegradable glove is extensively studied. A bio-based filler is extracted from food waste and blended into natural rubber latex (NRL) as a composite NRL. The effect of biodegradability of composite NRL was studied by varying the loading of bio-based filler in a form of starch dispersion and blended into NRL mixture. Herein some amount of starch can be extracted from cassava peel to be incorporated in NRL for a sustainable and yet biodegradable glove. Previous work on incorporation of cassava-peel filler in NRL has shown a biodegradability without compromising the pristine strength of NRL film at 50% loading starch. In this project, tensile strength and weight loss of prepared composite NRL films were optimised via Taguchi and Response Surface Method (RSM) by means of Design Expert software by varying starch/filler loading, curing temperature and curing drying duration. Due to inadequate data, the optimisation from that previous prepared composite NRL was compared with similar work which utilising NRL and bio-based filler. For Pulungan (2020) study, it can be concluded that the tensile strength of cassava peel starch biodegradable film has the best condition at 50°C to 60°C at approximately 5.5 hours. Elongation optimum conditions shows contrast value of temperature and time. Meanwhile, for Wendy (2020) study, it shows the best percentage loading of cassava-peel starch is at 20% to achieve high stress and strain at break. The optimised mechanical properties via Taguchi and RSM are rather different and hence validation on mechanical properties at above mentioned conditions need to be performed experimentally.

This paper provides a review about the challenges in product design and development (PDD) in the context of the Industrial Revolution 4.0 (IR 4.0), with a particular focused on the problems that may be encountered by the project management (PM) team in the PDD phase. In recent decades, there has been a large number research, design, and development studies related to IR 4.0, such as synthesizing the applications of Big Data, Internet of things (IoT), Cloud Computing, Cybersecurity, and Artificial Intelligence. The effect of this revolution in technology is changing rapidly with new models and methods of manufacturing that have been proposed for the new future. The pandemic Covid-19 also accelerates the interest in using all kinds of online technology. However, to adapt and achieve the benefits of this revolution, industry players have to encounter several issues related to the PM, especially during the PDD phase. The management challenges discussed in this study were divided into four categories: the project team member selection, team leader selection, identifying potential customers, and design for the environment. In addition, some of the solutions and recommendation has been described using several examples.

Published: August 2021

First aid kit has been used to treat minor pain or injuries before one can receive a qualified treatment from the medical doctor. It is found that the contents inside the first aid is only checked periodically and as a result, there is high chance that certain important medicine is not there by the time it is needed. Thus, the development of smart first aid kit that prioritizes on content management via intuitive display and voice instruction is presented in this paper. The developed smart first aid kit offers several unique features. The first is the use of infrared sensor to detect the availability of the first aid content. If the content is taken, the red LED will be lit up, and the user is notified through Blynk apps in smartphone and email by means of NodeMCU. The second feature is that the developed first aid is equipped with the Smart TFT LCD touch screen display and speaker. This smart touch screen can display the list of first aid contents as well as provide a quick button for voice instructions. The voice instruction button will play the recorded guidance and medical instructions in the form of phrases and voices. The programming for the touch screen display, the voice instructions (played by Arduino Mini MP3 module) and speaker are all processed by the Arduino Mega. Simple testing and analysis on sensor detection and notification revealed that both sensor and Blynk app work fine if the medications are placed in the correct position. In conclusion, a smart first aid kit with touch screen medications instructions menu equipped with voice instructions and the ability to alert the end user whenever the content of first aid is taken out has been successfully developed and executed in this study. All sensors and the programming for the touch screen and voice instruction work accordingly. For future work, several improvements are recommended such as better data management that has complete record on date, time, and name of the content that is taken out as well as alerting the user on the expiry date. This can help the person in charge to efficiently monitor the content in the first aid.

In our World of today, the quest to get rich at all cost without working for our money has led some of our youth into crimes such as robbery and kidnapping. As a result of this and by the sheer fact that vehicles are now very expensive to buy these days, there is a need for people to safeguard their vehicles against these hoodlums to avoid loss of their precious Assets to these rampaging criminals. Tracking is technology that is used by many companies and individuals to track a vehicle, an individual or an asset by using many ways like GPS that operates using satellites and ground-based stations or by using our approach which depends on the cellular mobile towers. Vehicle tracking system is a system that can be used in monitoring and locating a vehicle, avoid theft or recover a stolen vehicle, for monitoring of vehicle routes to ensure strict compliance to an already defined vehicle routes, monitor driver’s behavior, predict bus arrival as well as for fleet management. Internet of things has made it very possible to devices to inter communicate amongst themselves and exchange information, helping in acquiring and analyzing information faster that we used to know in the past and this has helped more especially in vehicle monitoring to ensure that vehicle owners feel safe about their investments without fearing about their loss. In this paper, we propose a vehicle monitoring system based on IOT technology, using 4G/LTE to get the get the coordinate, speed, and overall condition of the vehicle, process and send to a remote server to be analyzed and used in locating the vehicle and monitor its other configured parameters. This is realized using Raspberry pi, 4G/LTE, GPS, Accelerometer and other sensors with communicate amongst themselves to get the environmental parameters which is processed and sent to a remote server where it is analyzed and represented on a map to locate the vehicle and monitor the other set parameters. 4G/LTE provides fast internet connectivity with

This course has a very central place in studyingand seeing various problems that occur in this nation. Based on these symptoms, the writerdiscusses the role of Christian religion course in plural society. The author sees that thepresence of Christian Religion Course in the midst of a plural society becomes very importantso that believers can live and apply their faith in different areas. The writer wants to conveythat the followers of Christ should not be closed to differences, but believers must have thecourage to demonstrate God's love in the midst of the world as a manifestation of God'spresence itself since the condition of the Indonesian people is currently being shaken withvarious issues that can destroy the integrity of the Indonesian Nation. One of the issues thatoften occur today is terrorism, religious intolerance, hoaxes and politics.

Published: August 2021

Home range analysis is a standard and fundamental concept in ecology used to describe animal space use over their lifetimes. Connecting home range sizes with animal characteristics, location, and habitat can be used to inform conservation decisions. Reptiles are frequently lacking robust estimates of space use, particularly reptiles in tropical regions. Here we analyse a publicly available dataset, collected by the authors of this study, describing the movements of Critically Endangered Elongated Tortoises (Indotestudo elongata). The tortoise data included the locations of 17 tortoises (12 females, 5 males) collected on average once every three days for an average duration of 353.76 SE±33.10 days. We use these data to estimate the home range of Elongated Tortoise, and explore how tortoise size and sex influences home range size. To mitigate issues resulting from low effective sample sizes and low temporal resolution of the data, we used a modern home range estimation method – Autocorrelated Kernel Density Estimators (AKDE). We found 14 of 17 individuals appear to be occupying a stable home range (using variograms to determine range residency). The average AKDE home range for all 14 individuals with range residency was 44.81 ±10.44 ha. Bayesian Regression Models suggest comparable size estimates between male and female home ranges, despite males being physically larger than females in both mass and carapace length. These AKDE home range estimates have the added utility of being more comparable with other studies, less susceptible to errors from a suboptimal tracking regime, and are well positioned for inclusion in future meta-analyses.
Transdiagnostic Approaches to Sexual and Gender Minority Mental Health
Authors: Eaton Nicholas R , Rodriguez-Seijas Craig Anthony , Pachankis John E.
Published: August 2021

Sexual and gender minority individuals experience minority stress, which is hypothesized to underlie the mental health disparities affecting these populations. Drawing on advances in mental disorder classification, we argue that transdiagnostic approaches hold great promise for understanding and reducing these disparities. In contrast to traditional diagnostic approaches, which have limited construct validity and produced a piecemeal literature, transdiagnostic approaches: (1) are evidence based, (2) account for diffuse patterns of disparities and comorbidity, (3) pinpoint psychological mechanisms linking minority stress to poor mental health, (4) reduce scientific stigma, and (5) serve as efficacious and efficient targets for transdiagnostic minority stress interventions.

Published: August 2021

Background: Adolescents often look to their peers for emotional support, so it is critical that they are prepared to take on a supportive role, especially during a health crisis. Using a pilot randomised controlled trial (ISCRN registry, number ISRCTN99248812), we tested the efficacy of an online training programme designed to equip young people with skills to support to their peers’ mental wellbeing during the COVID-19 pandemic. Methods: We recruited one hundred young people (aged 16-18) living in the UK, through social media advertisements. In June 2020, participants were randomly allocated (1:1) to immediate 5-day peer support training (n=50) or a wait-list (n=50) via an independently generated allocation sequence. Primary outcomes were indicators of ability to help others (motivation, perceived skills, frequency of help provided, compassion to others and connectedness to peers). Secondary outcomes included emotional symptoms, mental wellbeing, and indicators of agency (civic engagement and self-efficacy). We also collected qualitative reports of participants’ experience. Assessments were completed at baseline and 1-week post randomisation (primary endpoint), and up to 4-weeks post-randomisation (training group only). Results: We found significant effects of online peer support training on all indicators of ability to help others, except for motivation to provide support. The training increased perceived support-giving skills, frequency of providing support, compassion and peer connectedness 1-week post-randomisation, compared to controls (medium-large effect sizes). Gains in the training group were maintained 4-week post-randomisation. Training also produced benefits in relation to emotional symptoms, wellbeing, and indicators of agency, and qualitative reports revealed further positive outcomes including increased personal self-care and feelings of empowerment. Conclusions: Online peer support training brought benefits across a range of outcomes. Leveraging digital platforms that are familiar to young people, peer support training has the potential to enable adolescents to support their own and their peers’ mental wellbeing during a health crisis.
Military Organizational Culture in Protest Response
Authors: Lotito Nicholas
Published: August 2021

When mass protests overwhelm the capacity of the police, civilian authorities often rely on soldiers to restore order. I argue that the military relies on historical precedents to guide its institutional response to protests. Soldiers rely on the military's organizational culture, a set of shared values, assumptions and beliefs, to guide their decision making. Military responses, from violent repression to complete disengagement, are driven by soldiers' shared understandings about their proper roles and missions, duties and responsibilities, and relationship to both ruler and ruled. Evidence from the Arab Spring protests of 2010-2011, and causal process tracing in the Tunisian case, provide support for the theory. The role of the military in producing Tunisia's largely nonviolent, prodemocratic regime transition has been widely lauded by scholars and policymakers alike. However, existing explanations for this outcome – namely, the lack of regime patronage toward military officers – do not fit the observed pattern of military response. Rather than move to oust Ben Ali, the military was generally loyal and never disobeyed his orders. Instead, the army's culture of restraint led soldiers to intervene to defend state institutions, but to avoid arbitrating or escalating the dispute.
"Let's get back to normal!" COVID-19 and the logic of cure
Authors: Berghs Maria
Published: August 2021

The COVID-19 pandemic has inversed certainties of absolutes of cure in everyday life but paradoxically this has occurred during a time when novel scientific advancements seem to herald a new frontier of cures for rare diseases, chronic conditions, disabilities and viruses that were previously incurable. In this paper, I illustrate the development of a logic of cure by first of all noting a lacuna in the medical sociological and anthropological literature, where although a lot of empirical research and theoretical work to understand cure has been undertaken, there has been no sociology or anthropology of cure. Using three case studies, I examine what they reveal about the logic of cure. Firstly, I argue that there is a development of a bioethics of cure in reactions of disability community and disabled people to care as cure during the COVID-19 pandemic. The second case-study focuses on understanding limitations of vaccines and how people react against such indeterminancies of loss of absolutes of cure. Lastly, the final case study describes how while there are cures, for example, for rare genetic conditions, they are often curated with long-term cost-benefit analysis for Global North. In conclusion, it is found that many of the developments within sociology and anthropology are missing from a logic of cure and that new theory of cure has to develop.
The New Empirics of Industrial Policy
Authors: Lane Nathaniel
Published: August 2021

Nations have and will continue to shape their economies through industrial policy. Nevertheless, the empirical literature on these interventions is thin, dwarfed by the attention industrial policies receive from policymakers across the world. In this paper, I discuss the difficulties of empirically studying industrial policy and review how new econometric work is confronting these issues. Through careful research design and attention to institutional detail, I argue that emergent studies are rapidly expanding what we know—and updating what we thought we knew—about these policies. As well, I argue tools from policy evaluation allow us to study the impact of endogenous industrial interventions. This review is a proposal to take industrial policy, along with their complexities, more seriously as objects of inquiry. Doing so requires not only more serious evaluations of past policy but also a reevaluation of past empirical work and consensus.

Introduction: Unstable distal radius fractures in children have more tendencies to get displaced with conservative management resulting into deformity. This Kapandji technique of K-wire fixation is on rise to reduce and maintain these fractures in recent days.
Aims: The aim of this study was to evaluate the effectiveness of the K-wires fixation in unstable distal radius fracture with Kapandji techniques.
Methods: A cross-sectional observational study was conducted in Nepalgunj Medical College and Teaching Hospital, Kohalpur, Banke in unstable distal radius fracture in children with K-wires fixation using Kapandji method.
Results: Twenty eight unstable distal radius fractures in children between 6 to 14 years of age were treated with one intrafocal K-wire and one or two extra focal K-wires to augment fixation. Immobilization of forearm with above elbow slab/cast for four to six weeks was enforced. K-wires were removed between four to six weeks of operation depending upon the union and followed prospectively for four months. The mean age of patients presented was 8.57± 1.79 years. This technique brought near anatomical reduction in all fractures. There was no reduction loss or remanipulation in any case. All fractures achieved union and functional outcome was excellent in 24 cases based on Modified Mayo Wrist Score. There was fewer complications like pin tract infection.
Conclusion: This Kapandji technique of K-wire fixation, leverage reduction method, being an additional tool helps to achieve near anatomical alignment, and maintain reduction throughout the duration of healing. So it is an advantageous technique.
Optimization of truck allocation in open pit mines using differential evolution algorithm
Authors: De Melo Willian B.
Published: August 2021

The allocation of trucks in open pit mines is a field with great potential for optimizing resources and applying advanced computer modeling techniques, mainly because many companies still choose to use manual allocation, which is premised on the decisions made by the operator, being subject to common failures and not reaching the maximum potential that the equipment can provide. Therefore, this work focuses on optimizing the allocation of trucks in order to increase production, reducing queue time and keeping ore grades within proper limits. The proposed algorithm was based on the differential evolution technique, where two types of mutation operators were used: rand/1/bin and best/1/bin, thus verifying the most suitable to solve the problem. The trucks were allocated in the ore loading and unloading process, aiming to improve the production capacity in a virtual mine. The results brought a convergence to the maximum global production, in addition to which, the allocation of unnecessary transport equipment to the planned routes was avoided. The two mutation operators compared had certain advantages and disadvantages, each better adapting to certain types of situations. The proposed technique can still be extended to other areas, for example, in the transport of grain on the road network or in the implementation of an allocation in freight cars that transport grain.

The study analyzed the factors affecting social-emotional competence (SEC) at the secondary level. A stratified random sampling technique was used. 382 students were taken as a sample after using desired sample size table. Two research tools were used, the Factors affecting social, emotional competence questionnaire and the Social-Emotional Competence Questionnaire (SECQ). Data were analyzed by using mean, percentage and standard deviation. Results indicated that friends response, classroom environment and home environment affects SEC the most as compared to media interaction. It was concluded that self-consciousness, social consciousness and the factor decisiveness were possessed by the students the most. And the factor self-regulation was possessed by the students the least. The skills in which the students were weak included calming down, dealing with wrong things and skill of staying positive during crises.
William Wordsworth, Matthew Arnold and Walter Pater: The Romantic Notion of Education and its Relation to Culture
Authors: Khan Sajjad Ali
Published: August 2021

This research paper examines the relationship between Arnold, Pater and modernism through the mediation of Wordsworth's ideas on education. Arnold's ideas on education are inspired by Wordsworth, and Arnold remains the most influential critic and theorist of education in the 'Wordsworthian tradition'. It is important to acknowledge the centrality of Arnold's ideas since Wordsworth's influence on later writers was largely mediated through Arnold's writings. Arnold echoes the best of Wordsworth in his best prose work, Culture and Anarchy. Education is a great help to culture as he says emphatically that 'education is the road to culture'. He recommends 'the right educative influences…under the banner of cultural ideals'. Arnold's influence on Pater is well-known (even if he departs from him). Wordsworth is a common source of influence on both Pater and Arnold. It is argued that Pater's aestheticism is not simply its anti-bourgeois, anti-Christian quality but its links to the notion of education and development.
THE CONCEPT OF CONVERTING TEXT INTO A BIT MAP USING ANY FONT

The modern world is impossible to imagine without the exchange of information. Newspapers, magazines, books, printed advertising products play an important role and are constantly being improved and require more and more resources and opportunities. At the moment, due to the sharp growth of digital technology, there is a problem between the capabilities of hardware and software. That is, when transferring data from the electronic world to paper, the difference between the computing capabilities of hardware and software is displayed. This applies to print media that cannot convey the full volume and depth of what is displayed on the screen. Raster fonts are used for printing faster, the main drawback of which is their non-scalability. When studying fonts in embedded systems, there were problems with the fact that there are quite a few ready-made options for converting text to a bitmap without certain restrictions. The font displayed on the screen and printed directly by the printer or other device may differ significantly because the number of pixels that can be printed is too large. Therefore, there is a need to optimize the conversion of the font into a bitmap, ie reducing the number of points without losing the base of the glyph. The paper presents the conversion of a font into a bitmap using a program based on a ruler, ie the division of the image into lines, which is used in printing. In order to create the required bitmap image in the program, you need to specify a specific glyph and its size, as well as the device for which it will be used. The scan converter takes a path and applies a set of rules to determine which pixels will be part of the glyph image when printed or displayed on the screen. The obtained results allow us to print the fonts we like, instead of the standard ones.

Published: August 2021

The article considers the current state of the system of maintenance and repair of agricultural machinery, shows the analysis of the existing system and its impact on the economic efficiency of production in the agro-industrial complex. The current state of instrumentation, electronics and computer technology can significantly increase and expand the possibilities of both diagnosing and forecasting based on it. The combination of these capabilities with the progress of agricultural machinery ensures its reliable, highly productive and economical operation. It is established that of great importance in the production of crop and livestock products is the qualified use of agricultural machinery, including its diagnosis, maintenance and technological maintenance and repair. The quantity and quality of the received production, its competitiveness, labor costs, fuel consumption and degree of influence on environment depend on quality and timeliness of carrying out service – diagnostics at technical and technological service. Improving the use of agricultural machinery and reducing the cost of its operation provides the use of technical diagnostics of machines as an information basis for the management of maintenance and repair processes. The practice of using diagnostic tools indicates the possibility of reducing operating costs. This is achieved by increasing the actual resource used, reducing the number of repairs and saving spare parts. To effectively apply existing diagnostics and development of new, engineering and technical workers of agricultural enterprises must have knowledge that reveals the fundamental side of the diagnosis. Measures of preventive influences which provide maintenance of necessary indicators of reliability and working capacity of cars during time of use are executed on a scientific basis, practical use and research of processes of wear and other deviations of details are developed.
