This study aimed to verify the efficiency of indicators of measure of physical attributes’ alterations and to refine the Srelative determination method in order to increase its sensitivity to soil physical alterations. Soils under Ficus carica L. cultivation (with 0, 20, 40 and 60% of liquid bovine biofertilizer in the irrigation depth) and under forest were used. Parameters evaluated included soil granulometry, soil bulk and particle density, soil water retention curve (SWRC), porosity and the indices S and Srelative. The experimental design was completely randomized with four replicates. For Srelative refinement, with the SWRC containing only textural porosity, the soil was dispersed in water and with the addition of 1 N sodium hydroxide (with and without removal of sodium through washing). An ANOVA was performed for 0, 20, 40 and 60% of biofertilizer in 0-10, 10-20 and 20-30 layers; Dunnett test was used to compare the mean values of S-index and Srelative-index. With respect to four methods to obtain the Srelative-index the means were compared by Tukey test. Tests of line parallelism and intercept were performed for the regressions between each of the soil physical variables and Srelative-index obtained. It was found that S and Srelative indices were sensitive to soil physical alterations caused by the application of the biofertilizer; Srelative-index was sensitive to variation in soil bulk density and total porosity and the Srelative-index obtained from the method of soil dispersion in water is more sensitive to soil physical alterations in comparison to Srelative-index obtained through ADFE.

Authors: Kamutando Casper Nyaradzai , Magorokosho Cosmos , Dari Shorai
Published: February 2018

The International Centre for Maize and Wheat Improvement (CIMMYT) develops maize (Zea mays L.) inbred lines and hybrids yearly that have several breeding and commercial attributes. However, no genetic analysis has been done on the recently developed inbred lines for yield performance under drought and low-N stress. The objectives of this study were to identify lines with positive general combining ability (GCA) effects for grain yield under stress environments and to identify the best single-cross hybrids with the highest specific combining ability (SCA) effects. Analysis of variance combined across sites showed significant mean squares for genotypes, locations and genotype by environment interaction (GEI) for grain yield. GCAlines, SCA and components of interaction effects were significant across sites. Additive genetic variance was more important than dominance variance in determining yield performance across locations indicating that selection based on grain yield under drought and low-N stress can be effective. Average grain yield across the eight locations ranged from 1.61 t ha-1 to 10.63 t ha-1 while narrow sense heritability for grain yield was 52.6% across sites and was slightly lower under managed drought and low-N stress. The testers CL115807 and CL106622 showed positive and significant GCA effects for yield performance under drought and low-N stress respectively. The best tester across all sites was CL115793 and line CZL0713 had consistently positive GCA effects for grain yield across sites. CML536 × CL115802 and CML312 × CL106508 were the best single crosses under low nitrogen stress sites while hybrid CML312 × C323-45 showed the highest positive SCA effects across sites. In conclusion, our results show that CIMMYT has new lines that have desirable adaptive attributes when grown under drought and low nitrogen stress environments in the mid-altitude region; hence these can be adopted for hybrid, synthetic and OPV formation.

Biological control is a method of controlling pests through the use of other living organisms. The purposes of this study were to test Hohenbuehelia species as biological control agents against Panagrellus redivivus in vitro, evaluating nematodes influence on mycelia growth; establishing daily indexes for predation and growth and setting predation percentage. Five species previously identified as 436-Hohenbuehelia mastrucata (Nematoctonus hamatus), 528-H. bullulifera (not described so far), 581-H. paraguayensis (N. sp.), 582-H. sp. (N. sp.) and 631-H. portegna (N. campylosporus) were submitted to anamorphic purification directly from basidioma. Afterwards, 100 nematodes were added to each pure colony for predation test. Evaluation started right after 24 hours of nematode-fungus interaction. Immobilized and/or penetrated nematodes were counted and mycelia growth was measured. Results were subjected to variance analyses. Hohenbuehelia mastrucata had the best performance in growth speed, followed by H. portegna and H. paraguayensis; Nematodes multiplyied much but none specie grew more as an influence of their movement under mycelium, however all species formed trap devices and some of them produced adhesive or repelent substances. Trap devices were formed in control plates also. The plates of H. paraguayensis without nematodes grew more than treatments. Cumulative predation of H. portegna was the highest at 24 (195.5%) and 48 hours (235%). At the last evaluation day, H. paraguayensis preyed the same amount (185.75%) than H. portegna, followed by H. mastrucata (109.51%). Resulst of predation daily indexes displayed chronological activity for each isolate, where H. portegna was very reactive at first 24 hours, H. mastrucata raised its predacious activity in 48 hours being constant from this time on and H. paraguayensis pointed out itself at 72 hours. Other species presented low predation and growth indexes throughout experiment.
Sustainable Intensification of Global Agronomic Output
Authors: Dybro Niels , Hansen Alan Christopher
Published: February 2018

Agribusinesses are investigating sustainable ways to meet the predicted increased demand for food production due to an increasing world population and higher living standards. Therefore, there is a strong need to increase agronomic output. This paper will review the current state of agricultural production of the main annual top-five staple grain crops grown around the world, their current yields and harvested area averages and trends. It concludes with a discussion of which changes are needed to increase the yield in lower yielding areas of the world. Finally, there is an assessment of what level of yield increases that could be attained provided the proposed changes are made and its predicted impact on food security by 2050.The current yield trends and trends for harvested area, when extrapolated out to 2050, indicate crop production will increase 106%. This includes an expansion of the total crop production area by 31%. This increase of cropping area can be achieved by increased utilization of available, uncropped land suitable for crop production, increased double cropping, and relay intercropping, allowing for multiple crops in a calendar year.In order to double crop production by 2050, it is necessary to focus on growing crops where the conditions make it possible, adopt the best sustainable crop production practices and implement them as intensively as possible everywhere, and consider improved crop production machine system options to reduce risk of soil compaction, which can reduce crop yields.With proposed changes across the world, it will be possible to exceed a doubling of food production by 2050 relative to 2005 levels, providing a reasonable high level of food security, absent wars and widespread natural disasters.

The evolution of Brazilian agricultural mechanization increased, within with the cultivated area, searching to satisfy the demand for food. The agricultural tractor is the main source of power in meeting this demand. However, due to its increasing use, incidents have been observed in public roadways. The lighting and signaling elements of these machines are critical in preventing these occurrences, and there is, in Brazil, legislation in this area, the CONTRAN (National Traffic Council) and the Ministry of Labor. The objective of this study was to demonstrate the evolution and application of the Brazilian law for the lighting and signaling requirements for tractors on public roads traffic and relate these aspects to scientific studies relevant to the topic. Through the study, it was observed that there was an evolution in the Brazilian legislation, especially since 2014, with the term of CONTRAN Resolution no. 454. From this evolution, there was misalignment between the items required by the different legislative bodies on the subject and, in addition, the provisions from both the CONTRAN and the Ministry of Labor have no technical and/or dimensional requirements relative to the location of items on the machine. The scientific studies analyzed showed that there was also progress in the implementation of legislation in new agricultural tractors. However, it is not enough for the machine to leave the factory in a proper way, it must be maintained in working conditions for its operation. Finally, it was observed the need for the implementation of awareness campaigns on the context of road safety and the use of methods for assessing their effectiveness.

Sugarcane extracts and accumulates high amounts of soil nutrients, because it produces large amounts of biomass. Nutrient contents for varieties widely used in the past can be found in the literature, but there is little information on current cultivars. In view of these considerations, the study aimed to determine the nutrient concentration in the shoot biomass of sugarcane varieties in the first regrowth cycle. The study was conducted at a Latossolo Amarelo in Fazenda Jequiá, located in the state of Alagoas, Brazil. The experiment was a randomized block design with five replicates, consisting of four sugarcane varieties: SP813250, RB867515, RB92579 and VAT90212. At maturity of the first regrowth sugarcane, nitrogen (N), phosphorus (P), potassium (K), Ca (calcium), Mg (magnesium), S (sulfur), zinc (Zn), iron (Fe), copper (Cu), manganese (Mn) and Boron (B) contents were determined. Varietal differences were found in nutrient contents. However, no variety showed higher concentration for all the elements. The varieties showed the following order of macronutrient concentrations: K > N > Ca > Mg > S > P. The average values were 0.47, 0.08, 0.66, 0.15, 0.13 and 0.11 dag kg-1 of N, P, K, Ca, Mg and S, respectively. Concentrations of 9.9, 98.7, 29.2, 1.9 and 4.4 mg kg-1 of Zn, Fe, Mn, Cu and B were found for the micronutrients, respectively.

Published: February 2018

Neem tree extracts from root, bark and leaves have generally been used in the control of pests. The extracts’ efficacy in the control of aphids in cabbages under smallholder farming systems formed the subject of the study. The dose of the admixture of the extract that effectively controlled aphids was determined through experimental methods that involved harvesting and crashing 0.1 × 10-4 of Neem tree parts. The extract was fermented for 18-48 hours.Treatment tests solutions varied were 20 mL, 30 mL and 40 mL of the extract respectively in 10litres of water and applied to cabbage in the field at intervals of once a week, twice a week and once in 2 weeks in a triplicated completely Randomized Block Design. The treated plants were observed for average number of live aphids, number of dead aphids, degree of leaf perforation, leaf curls, stunting, and finally the yield of the cabbage visa vis treatments. Aphid counts at the concentration of 30mL in 10L of water were significantly lower for live aphids and higher for dead aphids (P < 0.05), Although all treatments revealed significant differences from the control in terms of Aphid mortality, overall mean aphid counts showed a reduction in number (implying high mortality) with an increase in the concentration of Neem extract applied and cabbage vigour increased with increase in the frequency of admixture application, with a bi-weekly application producing significant results (P < 0.05). High concentration (40 mL) more effectively controlled aphids but resulted in mild scorched leaves. Smallholder farmers should take advantage of the naturally available Neem tree concoctions of 30 mLs in 10litres of water twice a week to keep aphid’s population below the economic injury level.

Chia (Salvia hispanica L.) is an herbaceous plant that belongs to the Lamiaceae family. Seed vigor testing is an important component of quality control programs, and electrical conductivity test is a possible option in this process. The objective of this study was to identify a methodology of electrical conductivity test to stratify chia seed lots at vigor level according to the emergence of seedlings. Six lots of chia seeds were used in this study. The seeds were exposed to the following determinations: first germination count, germination, emergence speed index, emergence, aerial and root length, aerial and root dry matter, and electrical conductivity at 25, 50 and 75 mL during 1, 2, 4, 6, 8 and 24 hours of soaking in water. The electrical conductivity test in the combination of 25 seeds using 50 mL of water in 6-hour of soaking period, as well as the combination of 50 seeds using 50 mL of water for 24 hours of soaking, were efficient in the stratification of chia seeds in different levels of vigor.

Published: February 2018

This study describes online shoppers, explains their interests in learning about market outlets for locally/regionally grown fresh produce, and analyzes their preferences for channels to receive educational information concerning local/regional fresh produce. We used a K-mean clustering algorithm together with binary and ordered Logit models to analyze data collected in 2016 from a stratified randomly selected sample of 1,205 online shoppers within the U.S. South region. We found that the probability for online shoppers to be interested in learning about market outlets for local/regional grown fresh produce is 66 percent. Results also indicate that the likelihood for the word-of-mouth to be at least preferred (preferred, very preferred, and extremely preferred) as channel to receive educational information about local fresh produce is 69 percent. The probabilities for local radio/TV stations, Internet-based, newspapers, and ads on public places to be at least preferred are 61 percent, 48 percent, 57 percent, and 66 percent respectively. Findings from this study are useful for fresh produce growers, agricultural marketers and educators, online shoppers, and further research studies.

Main principle of the common agricultural policy of European Union is achievement of high results with the least possible negative impact on the environment, land protection and efficient use of natural resources. For that purpose, a number of studies are carried out, related to the improvement of biodiversity and protection of the pollinators in the areas of production. Two type of grass mixes were observed: “Laitamag” (Hungary) composed of White mustard (Sinapis alba L.), White clover (Trifolium repens L.), Phacelia (Phacelia tanacetifolia Bentham), Crimson clover (Trifolium incarnatum L.), Egyptian clover (Trifolium alexandrinum L.), Red clover (Trifolium pretense L.), Wild oats (Avena sativa L.), Alfalfa (Medicago sativa L.), Buckwheat (Fagopyrum esculentum Moench) and Sainfoin (Onobrychis viciifolia Scop.) and a mix, proposed by the Agrarian University: White mustard (Sinapis alba L.), White clover (Trifolium repens L.), Phacelia (Phacelia tanacetifolia Bentham), Buckwheat (Fagopyrum esculentum Moench), Coriander (Coriandrum sativum L.). The vegetation of the autumn crops began in March, as the blossoming lasts for 60-63 days, from the beginning of April until 24 June. For the spring sowing (18 March), the flowering of the mixes occurred later, in the second 10-day period of May and ended at the end of June. As a result of the low temperatures during winter, the white mustard, buckwheat and sainfoin plants perished. White clover proves to be the most resilient species.
Fuzzy Multilevel Graph Embedding for Recognition, Indexing and Retrieval of Graphic Document Images
Authors: Luqman Muhammad Muzzamil
Published: February 2018

This thesis addresses the problem of lack of efficient computational tools for graph based structural pattern recognition approaches and proposes to exploit computational strength of statistical pattern recognition. It has two fold contributions. The first contribution is a new method of explicit graph embedding. The proposed graph embedding method exploits multilevel analysis of graph for extracting graph level information, structural level information and elementary level information from graphs. It embeds this information into a numeric feature vector. The method employs fuzzy overlapping trapezoidal intervals for addressing the noise sensitivity of graph representations and for minimizing the information loss while mapping from continuous graph space to discrete vector space. The method has unsupervised learning abilities and is capable of automatically adapting its parameters to underlying graph dataset. The second contribution is a framework for automatic indexing of graph repositories for graph retrieval and subgraph spotting. This framework exploits explicit graph embedding for representing the cliques of order 2 by numeric feature vectors, together with classification and clustering tools for automatically indexing a graph repository. It does not require a labeled learning set and can be easily deployed to a range of application domains, offering ease of query by example (QBE) and granularity of focused retrieval.
Retinal Image Analysis Oriented to the Clinical Task
Authors: Marrugo Andres Guillermo , Millan Maria Sagrario
Published: February 2018

Ophthalmology can profit greatly from the analysis of digital images because they can aid in establishing an early diagnosis even before the first symptoms appear. This dissertation contributes to the digital analysis of such images and the problems that arise along the imaging pipeline of fundus photography, a field that is commonly referred to as retinal image analysis. We have dealt with and proposed solutions to problems that arise in retinal image acquisition and longitudinal monitoring of retinal disease evolution. Specifically, non- uniform illumination compensation[1], poor image quality [2], automated focusing [3], image segmentation [4], change detection [5], space-invariant (SI) [5] and space-variant (SV) [6] blind deconvolution (BD). Digital retinal image analysis can be effective and cost-efficient for disease management, computer-aided-diagnosis, screening and telemedicine and applicable to a variety of disorders such as glaucoma, macular degeneration, and retinopathy [7, 8].
SWT voting-based color reduction method for detecting text in natural scene images
Authors: Ikica Andrej
Published: February 2018

In our PhD thesis we give a very detailed and in-depth survey of natural scene text detection methods and propose two novel methods, namely SWT (Stroke Width Transform) voting-based color reduction method and SWT direction determination method. SWT voting-based color reduction method (to which we will refer also as SWT-V) is a novel text detection method that - opposed to many other text detection methods - combines both structural and color information in order to detect text. The proposed method upgrades the text detection oriented color reduction method (to which we will refer to as TOCR) with the additional SWT voting stage and substantially outperforms other state-of-the-art text detection methods. All the image colors rich with SWT pixels that most likely belong to text characters are blocked from being mean-shifted away in the color reduction process. One of the disadvantages of the SWT method, however, is the problem of ‘light text on the dark background’ described in the following sections. To cope with the problem and in order to provide true SWT values to the SWT voting stage we propose an adaptive SWT direction determination method. The method uses SWT profiles to partition an image into subblocks and analyzes their SWT histograms of both SWT search directions. Text detection literature does not explicitly address the SWT direction issue, therefore, the proposed method represents a unique scientific contribution to the research field. All text detection methods were evaluated on the CVL OCR DB text detection evaluation dataset.

Performance analysis of Enterprise Service Buses of Open Source type
Authors: Górski Tomasz , Pietrasik Kacper
Published: February 2018

The growing interest in business integration and interoperability of IT systems led to an increase in the importance of Service-Oriented Architecture (SOA), which provides tools for Enterprise Application Integration (EAI). In this sense, Enterprise Service Bus (ESB) provides technical capabilities for communication between IT systems. The aim of this article is to present the results of performance tests of selected ESBs of Open Source type. The basis for our performance analysis was a business case of the order realization in the Internet shop of electronics retailer. The order realization requires a collaboration of three IT systems. The business case has been implemented with the use of each selected ESBs: WSO2, Mule, and Talend. Test scenarios were defined and performance tests were conducted for each of the three selected ESBs. On the basis of the collected results it can be concluded that each service bus has its own strengths and weaknesses. Focusing on the merits it should be noted that WSO2 copes very well with files of small size, for small number of users, and also does not burden the CPU significantly. Results for Talend ESB, show that it does well with both kind of files, small and large sizes, for large number of users, but harder utilizes CPU. Research shows that it is worth to analyze the parameters of transmitted messages while selecting ESB for building integration solution. The results show that the Talend ESB may be a good choice for construction of integration solution in a business environment with a large number of users and diversified communications.

A MINE AS AN OBJECT OF CRISIS MANAGEMENT
Authors: TARASZKIEWICZ-ŁYDA Maja
Published: February 2018

The article deals with problems connected to crisis management regarding mining com-panies. In accordance with adequate decrees, mining companies, including mining plants, belong to objects towards which crisis management rules should be applied. In mining plants, apart from underground threats, ground threats that lead to a crisis situ-ation might also emerge on the entrepreneur’s territory. By this reason, they should be guided by the principles for the preparation for their special protection through concep-tual, planning, organizational, logistic, technical, training and control activities taken to develop, agree and update specific protection plans, implement projects under the alert and notification system, and exchange information on threats. A summary of possible hazards to a particular site and a separate mining plant facility, assessment and risk control are essential to develop a safety concept and prevent risks. There is a need of continual analyses of potential threats and actions taken to eliminate them, and if they occur the rapid response of individual services and appropriate integrated rescue opera-tions.

Reduction in the number of fatalities of road accidents is dependent on investment in transport infrastructure, the development of safety sys-tems for means of transport and the care for the technical condition of vehicles. Fur-thermore, the human factor is manifested in the growing awareness of hazards and im-proving skills of vehicle drivers. The article presents the construction, operating principles and technical capabilities of the most commonly used hydraulic rescue tools. All this was presented against the background of selected problems occurring during rescue opera-tions while releasing victims caught in car wrecks.
THERMOPLASTIC POLYMER MACHINE GUARDS – EXPLOITATION SAFETY
Authors: UBOWSKA Agnieszka
Published: February 2018

The machine construction sector uses from 2 to 5% of thermoplastic polymer produc-tion. This material is used to make small elements and big parts of equipment, includ-ing guards. The latter have mechanical vibration damping capacity, do not require any maintenance, are cheap and look attractive. Moreover, polymer guards are an essen-tial element of machines as they improve workplace safety. They are used in such ma-chines as lathes, milling machines, drills, extruding machines, presses and grinders. Pursuant to the Ordinance of the Minister of Labour and Social Policy on general provi-sions for safety and health at work, protective devices used in machines should be strong and durable so as to ensure the appropriate level of occupational safety. This is why the selection of the right material to make such devices is essential. Most fre-quently guards used in the market are steel frames with a polycarbonate screen or lam-inated safety glass. Other materials used to manufacture guards are poly(methyl methacrylate) (PMMA) and polystyrene (PS). Thermoplastics are characterised by high visual light transmittance (even up to 98% in the case of PMMA), easy treatment, pos-sibility to form any shape and resistance to atmospheric factors. However, they are also characterised by limited high temperature resistance, low fire resistance and high speed of fire propagation on their surface which may be dangerous for employees in case of fire. The article discusses the selection of appropriate material for the produc-tion of guards in the context of their exploitation in higher temperature conditions and examines threats posed by thermoplastics in fire conditions.
The comparison of electrooptical properties of PDLC liquid-crystalline composites in visual and near-IR ranges
Authors: Sułkowski Krzysztof , Węgłowski Rafał , Kłosowicz Stanisław J.
Published: February 2018

Electrooptical properties of conventional Polymer-Dispersed Liquid Crystals (PDLC) composites were compared in visual and near-IR ranges for the electrically-induced light transmission effect. It was confirmed that the most important for the optical contrast value is the matching of refractive indices of the polymer matrix and dispersed droplets of liquid crystal, as well as matching droplet size and wavelength of incident radiation. The optimization of electrooptical parameters of such materials needs new liquid-crystalline mixtures dedicated for near-IR range. The studied effect can be applied for manufacturing window glasses with electrically adjusted transmission of infrared radiation.

Model of a filtration process using a membrane filter with uniform transmission structure
Authors: Górka Andrzej
Published: February 2018

The paper presents a model of a microfiltration filter for separation of biological microparticles from body fluids, including peripheral blood. The model used a single membrane filter with a homogeneous 2D transmission structure. In the model, the individual sieve with a uniform transmission structure in 2D space was applied. Because of the required survival of biological particles, the presented model was limited to the narrow filtration conditions that guarantee biological activity of these particles. In this model, the filtration process proceeds in the gravitational field without the involvement of external forces forcing or inhibiting the filtration process. Based on this model there were given basic dependencies describing the required filtration process conditions, such as filtration time and internal forces for particle migration in the filtered body fluid. The basic relationships between the height of the filtered column, duration of the process, and average fluid expenditure of the filtration process for different shapes of the channels molecular drainage lines filter have been determined. Based on this data, the directions of further works on improving the presented model of molecular filtration of biological particles for enriching selected biological fractions have been described.

EVOLUTION OF RUSSIAN ASSAULT- BREACHING SUBUNIT
Authors: DEPCZYŃSKI Marek , KUCHTA Wiesław
Published: February 2018

In the Russian military art, the effectiveness of combat operations is largely dependent on the capabilities of the military engineering. It can be assumed that the capabilities of engineering forces are one of the major determinants of the efficiency of military operations. Taking into account the assumptions of contemporary operational art and tactics, the military engineering forces are constantly evolving, which results in their adaptation to the changing requirements of the environment of the operations being carried out. In this light, urbanized areas, including large agglomerations, are supposed to be places where engineering tasks will be executed. Based on the experiences of modern armed conflicts, Russian military engineers are primarily prepared for actions in the built-up environment. In the opinion of Russian specialists, the implementation of tasks in urban agglomerations requires the involvement of subunits, which ensure the maintenance of maneuverability, thereby increasing the effectiveness of combat measures used. One of the preferred solutions is to form, mainly on the basis of engineering troops, specialist task forces as assault-breaching subunits. Such an approach to adjusting (modernizing) the Russian Federation’s military engineering forces to the requirements of modern warfare is not revolutionary, but a permanent evolutionary process.

POSSIBILITIES FOR THE USE OF BIOMETRIC DATA IN SECURITY SYSTEMS
Authors: KOPCZEWSKI Marian , SMAL Tomasz
Published: February 2018

Possibilities for the use of biometric data are growing and hence their practical application is also increasing. Therefore, an important element to be considered in the design, construction and exploitation of systems using biometrics is the question of identifying a specific person and assigning him or her to the relevant data contained in the documents or databases. The ability and, in some cases, the need to use biometric data results from the growing use of information technology in everyday life and the ever increasing attempts to steal the identity of those using these technologies. Modern IT systems often have a high level of security in terms of protection and access to data, and in particular the management of security systems. The article presents an outline of the theory related to the possibility of using and applying biometric data to provide security and have the ability to inspect officers of various departments. The subject of analysis also considered the possibility of using security measures in the form of biometric data identification for the purpose of securing the security services.

In the study, the authors focused on determination of reliability indicators of the transport systems, which currently constitute the Polish Armed Forces’ equipment. The methods of research of car fleets composed of distinct types of vehicles are presented. The algorithms of reliability indicators’ determination addressed in the study can serve to analyze other set of transportation means used in rescue, seasonal transport and specialized transportation assignments, as well as to determine the security level of any mission conducted. The appearance of information technology allowed transferring the paper-based registration system of operational occurrences into an integrated information system. It enables to follow the history of transportation fleets including single pieces of the equipment. The knowledge of reliability of particular types of the vehicles allows for proper planning of missions within the framework of possessed transport assets capacity. The study presents the method of achieving the intended objective to increase the effectiveness of management of motor vehicles fleet used intermittently. The algorithm for the selection of a vehicle or a group of vehicles for execution of tasks, developed on the basis of analytical procedures, envisages the assignment of mobile assets, complication and complexity of their structures, the level of modernity, operational history and branch regulations. Determined reliability indicators for particular groups of vehicles can be implemented into the Multilevel Information System
