AN OPTIMIZATION ALGORITHM BASED ON BACTERIA BEHAVIORijaia
Paradigms based on competition have shown to be useful for solving difficult problems. In this paper we present a new approach for solving hard problems using a collaborative philosophy. A collaborative philosophy can produce paradigms as interesting as the ones found in algorithms based on a competitive philosophy. Furthermore, we show that the performance - in problems associated to explosive combinatorial - is comparable to the performance obtained using a classic evolutive approach.

Feature Selection Approach based on Firefly Algorithm and Chi-square IJECEIAES
Dimensionality problem is a well-known challenging issue for most classifiers in which datasets have unbalanced number of samples and features. Features may contain unreliable data which may lead the classification process to produce undesirable results. Feature selection approach is considered a solution for this kind of problems. In this paperan enhanced firefly algorithm is proposed to serve as a feature selection solution for reducing dimensionality and picking the most informative features to be used in classification. The main purpose of the proposedmodel is to improve the classification accuracy through using the selected features produced from the model, thus classification errors will decrease. Modeling firefly in this research appears through simulating firefly position by cell chi-square value which is changed after every move, and simulating firefly intensity by calculating a set of different fitness functionsas a weight for each feature. Knearest neighbor and Discriminant analysis are used as classifiers to test the proposed firefly algorithm in selecting features. Experimental results showed that the proposed enhanced algorithmbased on firefly algorithm with chisquare and different fitness functions can provide better results than others. Results showed that reduction of dataset is useful for gaining higher accuracy in classification.

Kullback-Leibler (KL) optimality criterion has been considered in the literature for model discrimination. However, Hellinger distance has many advantages rather than KL-distance. For that reason, in this paper a new criterion based on the Hellinger distance named by Hellinger (ℋ) -optimality criterion is proposed to discriminate between two rival models. An equivalence theorem is proved for this criterion. Furthermore, a new compound criterion is constructed that possess both discrimination and a high probability of desired outcome properties. Discrimination between binary and Logistic GLM are suggested based on the new criteria

Abstract:Reactive Power Optimization is a complex combinatorial optimization problem involving non-linear function having multiple local minima, non-linear and discontinuous constrains. This paper presents PS2O, which extends the dynamics of the canonical PSO algorithm by adding a significant ingredient that takes into account the symbiotic co evolution between species, Hybrid Evolutionary-Conventional Algorithm (HECA) that uses the abilities of evolutionary and conventional algorithm and Genetical Swarm Optimization (GSO), combines Genetic Algorithms (GA) and Particle Swarm Optimization (PSO).All the above said algorithms is used to overcome the Problem of premature convergence. PS2O, HECA , GSO is applied to Reactive Power Optimization problem and is evaluated on standard IEEE 57, practical 191 test Bus Systems. The results shows that all the three algorithms perform well in solving the reactive power problem and prevent premature convergence to high degree but still keep a rapid convergence. Of all the three PS2O has the edge in reducing the real power loss when compared to HECA & GSO.

A study of tipping point: much less is known about the most efficient ways to reach such transitions or how self-reinforcing systemic transformations might be instigated through policy. We employ an agent-based model to study the emergence of social tipping points through various feedback loops that have been previously identified to constitute an ecological approach to human behavior. Our model suggests that even a linear introduction of pro-environmental affordances (action opportunities) to a social system can have non-linear positive effects on the emergence of collective pro-environmental behavior patterns.

Overview combining ab initio with continuum theoryDierk Raabe
Multi-methodological approaches combining quantum-mechanical and/or atomistic simulations
with continuum methods have become increasingly important when addressing multi-scale phenomena in
computational materials science. A crucial aspect when applying these strategies is to carefully check,
and if possible to control, a variety of intrinsic errors and their propagation through a particular multimethodological
scheme. The first part of our paper critically reviews a few selected sources of errors
frequently occurring in quantum-mechanical approaches to materials science and their multi-scale propagation
when describing properties of multi-component and multi-phase polycrystalline metallic alloys.
Our analysis is illustrated in particular on the determination of i) thermodynamic materials properties at
finite temperatures and ii) integral elastic responses. The second part addresses methodological challenges
emerging at interfaces between electronic structure and/or atomistic modeling on the one side and selected
continuum methods, such as crystal elasticity and crystal plasticity finite element method (CEFEM and
CPFEM), new fast Fourier transforms (FFT) approach, and phase-field modeling, on the other side.

In this work, using professional software Fuzzy Logic Toolbox from MATLAB 7.5 specifically that shows the simulation of a model that reflects organizational change process based on the approach to complexity at the Center for Environmental Engineering Camagüey (CIAC). This organization, as a social formation itself is immersed in an environment that maintains the mutual relations of influence, and it provides the organizational complexity and multiple aspects of uncertainty or fuzziness of its boundaries. It is through the interaction and interconnection of multiple and different factors in nature that based on the implementation of structural and functional systemic approach using a hermeneutic dialectic epistemology we intend to achieve in practice self-organization of the center. Each of these factors or variables, such as nonlinear phenomena in itself, defined by human thought that is imprecise by nature, is expressed by fuzzy sets with overlapping boundaries, which, together with the rule base (existing knowledge system) and the inference mechanism conforms the fuzzy inference system (FIS) that shapes the future conduct of the Center and the interrelationships between all variables. Integration into a single model of factors as diverse and yet highly interrelated with as participation, co-leadership and autonomy variable as "research & development willingness" and others like impacts, production, relevance and optimization to identify possible capacity variable analysis from a vision trans-disciplinary process of self-organization and school management.

Standardization and Formulations of Calotropis ProceraYogeshIJTSRD
Plants growing in arid regions have elicited increased attention, because the hostile environment, in which these plants survive, forces them to develop chemical protective systems through adaptation which is rarely found in vegetation of other ecosystems. Furthermore, many of the plants grow in areas, where the dependence on traditional, plant based medicines over industrially produced pharmaceuticals persists to this day. The two plants, Calotopris Procera giant milkweed, also named C. Persica and Calotropis gigantea crown ower , have been used widely in traditional medicine in North Africa, the Middle East, and South and South East Asia. This has led to extensive research on the chemical constituents of the plants. Both plants are known to be sources of cardenolides, and newer research has yielded a number of interesting cancer active constituents. In addition, extracts of both plants have remarkable nematocidal, molluscidal and insecticidal activities. In many regions, the wood of Calotropis plants has been used as a building material and as a source of fuel. In addition, certain parts of the plants have been used as feed for livestock. In other regions, Calotropis plants are seen as invasive species that threaten local plant life and that due to their toxicity also pose a threat to grazing eld animals.

Review of the Diagnosis and Treatment of ParalysisYogeshIJTSRD
Paralysis is a complete loss of motor power in any muscle group. When paralysis affects all four extremities, it is called quadriplegia when it affects only the lower extremities, paraplegia and when it affects the extremities on one side of the body, hemiplegic. For this reason, the term paralysis is generally reserved for more focal, less stereotyped weakness, for instance, affecting all the muscles innervated by a peripheral nerve. Many different anatomical lesions and etiologies can cause paralysis and determine its treatment. Bikash Debsingha | Dr. Gourav Kr.

Criminology Educators Triumphs and StrugglesYogeshIJTSRD
This research study is geared on determining the triumphs and struggles of criminology educators. Included on the aim is to know their experiences and story being considered as teacher by accident. A qualitative research design was applied in this study. Researchers conducted a personal interview with the respondents with the aid of a guide questions which all points to main issue of this study. The findings of the study revealed that out of seven respondents, four are on the age bracket of 21 to 25 years old, two respondents are on the age bracket of 26 to 30 years old and a single respondent is on the age bracket of 36 to 40 years. Most of the respondents find enthusiasm in teaching and are aware that there is a need for them to proceed in post graduate studies for them to have a considerable salary. As to financial stability, only 1out of 7 considers herself as financially stable. The rest are saying that as of the moment, they are not yet financially stable basing on the rate of their salary. Qualification matters a lot in the field of academe because this was being shared by one of the respondents who considers herself as financially stable. Also, all of the respondents do not consider teaching as their first career of choice but most of them does not have any plan of shifting to another career. Girlie N. Cañete | Harry Santiago P.

Automatic Query Expansion Using Word Embedding Based on Fuzzy Graph Connectiv...YogeshIJTSRD
The aim of information retrieval systems is to retrieve relevant information according to the query provided. The queries are often vague and uncertain. Thus, to improve the system, we propose an Automatic Query Expansion technique, to expand the query by adding new terms to the user s initial query so as to minimize query mismatch and thereby improving retrieval performance. Most of the existing techniques for expanding queries do not take into account the degree of semantic relationship among words. In this paper, the query is expanded by exploring terms which are semantically similar to the initial query terms as well as considering the degree of relationship, that is, “fuzzy membership- between them. The terms which seemed most relevant are used in expanded query and improve the information retrieval process. The experiments conducted on the queries set show that the proposed Automatic query expansion approach gave a higher precision, recall, and F measure then non fuzzy edge weights.

A New Proposal for Smartphone Based Drowsiness Detection and Warning System f...YogeshIJTSRD
This paper proposes a Smartphone based system for the detection of drowsiness in automotive drivers. The proposed system uses three stage drowsiness detection technique. The first stage uses the percentage of eyelid closure PERCLOS which is obtained by capturing images with the front camera of the Smartphone with a modified eye state classification method. The system uses near infrared lighting for illuminating the face of the driver during night driving. The second step uses the voiced to the unvoiced ratio VUR obtained from the speech data from the microphone, in the event PERCLOS crosses the threshold. The VUR is also compared with a threshold and if it is a value greater than that of the threshold, it moves on to the next verification stage. In the final verification stage, touch response is required within the stipulated time to declare whether the driver is drowsy or not and subsequently sound an alarm. To awake the driver, a vibrating mechanism is done and also the live GPS location is also sent to an emergency contact. We have studied eight other reference papers for the literature review. The system has three advantages over existing drowsiness detection systems. First, the three stage verification process makes the system more reliable.

Data Security by AES Advanced Encryption StandardYogeshIJTSRD
Now a days with the rapid development of multimedia technologies, research on safety and security are becoming more important. Multimedia data are generated and transmitted through the communication channels and the wireless media. The efficiencies of encryption based on different existing algorithms are not up to the satisfactory limit. Hence researchers are trying to modify the existing algorithm or even develop new algorithms that help to increase security with a little encryption time. Here in this paper, we have furnished a new technology to modify the AES algorithm which gives more security with a little encryption time and which can be used to encrypt using 128 bit key. Theoretical analysis on the proposed algorithm with the existing reveals the novelty of our work. Here we have proposed a technique to randomize the key and hidden the key data into an encrypted digital image using the basics concept of cryptography and also using the concept of digital watermarking, the concept of key hide has also been encrypted. We have also proposed a new technique to reposition the pixels to break the correlation between them. So, the proposed scheme offers a more secure and cost effective mechanism for encryption. Next on the AES criteria list good performance. Widespread market adoption will require reasonably good performance on a variety of platforms, ranging from easy tocrack smart cards to the largest servers. Good algorithm performance includes speed for the encryption and decryption process as well as the key schedule.

The study sought to determine the extent to which the usage of social media in the marketing of agricultural products in South West Nigeria can enhance farmers turnover. It employed the survey research design to collect data with the help of a structured questionnaire to elicit information from respondents selected from six 6 south western states. Research data were analysed using structural equation modelling. The results showed that the use of social media WhatsApp and Facebook in marketing of agricultural products significantly enhances farmers turnover. The managerial implication is that use of Whatsapp and Facebook in the marketing of agricultural products for the enhancement of farmers’ turnover was found to have significant influence on the enhancement in farmers’ turnover from agricultural products. Policy makers in government should provide the enabling environment for the telecommunication companies to enhance their reach by installing their facilities across the length and breadth of the country so that the network coverage will be strong at all times so that the benefits of social media usage will not be constrained.

A mathematical equation which involves a function and its derivatives is called a differential equation. We consider a real life situation, from this form a mathematical model, solve that model using some mathematical concepts and take interpretation of solution. It is a well known and popular concept in mathematics because of its massive application in real world problems. Differential equations are one of the most important mathematical tools used in modeling problems in Physics, Biology, Economics, Chemistry, Engineering and medical Sciences. Differential equation can describe many situations viz exponential growth and de cay, the population growth of species, the change in investment return over time. We can solve differential equations using classical as well as numerical methods, In this paper we compare numerical methods of solving initial valued first order ordinary differential equations namely Euler method, Improved Euler method, Runge Kutta method and their accuracy level. We use here Scilab Software to obtain direct solution for these methods.

Evaluation of Different Paving Mixes Using Optimum Stabilizing ContentYogeshIJTSRD
Bituminous mixes are most commonly used all over the world in flexible pavement construction. It consists of asphalt or bitumen used as a binder and mineral aggregate which are mixed together, laid down in layers and then compacted. Under normal circumstances, conventional bituminous pavements if designed and executed properly perform quite satisfactorily but the performance of bituminous mixes is very poor under various situations. Today’s asphaltic concrete pavements are expected to perform better as they are experiencing increased volume of traffic, increased loads and increased variations in daily or seasonal temperature over what has been experienced in the past. In addition, the performance of bituminous pavements is found to be very poor in moisture induced situations. Considering this a lot of work has been done on use of additives in bituminous mixtures and as well as on modification of bitumen. Research has indicated that the addition of polymers to asphalt binders helps to increase the interfacial cohesiveness of the bond between the aggregate and the binder which can enhance many properties of the asphalt pavements to help meet these increased demands. However, the additive that is to be used for modification of mix or binder should satisfy both the strength requirements as well as economical aspects.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

deep theoretical development of models, the inadequacy is
known in advance. Usually, a priori models are derivedfrom
theoretical assumptions, and a posteriori models are
constructed from empirical data.
Descriptions of the functioning of ATCs in ecosystems are
usually characterized by uneven knowledge of individual
processes. Often, not only is the mathematical form of the
dependencies between the individual components not
known, but there are no quantitative characteristics of the
processes at all.
An attempt to create models that combine physical-dynamic
and chemical-biological processes usually leads totheuseof
differential equations. The advantages of using systems of
differential equations as mathematical models of natural-
technical complexes include the fundamental possibility of
establishing general provisions of the theory of the
functioning of various systems.
One of the simplest models of population growth belongs to
T. Malthus, who noticed that populations tend to increase
exponentially. However, the growth of populations is
sufficiently constrained by such factors as the struggle for
existence, disease, natural death and destruction by
predators. Usually, if a population begins to develop in an
environment with a sufficient amount of food and with a
relatively small number of predators,thenatfirstitsnumber
grows very quickly. Over time, food supplies are depleted,
overpopulation leads to conditions less favorable for
survival, fertility decreases and mortality increases. Under
certain conditions, an equilibrium state is reached and the
population size becomes more or less constant.
The first model that takes into account the maximum
number that a population can reach in conditions of limited
resources was proposed in 1825 by B. Gompertz.

the producer, consult and substrate.
This form of recording means that only a certain part of the
mass of each substrate goes to the formationofnew biomass
of the species that consumes it. Everything is determined by
the energy and biochemical valueoftheconsumedsubstrate.
In the general case, differential models are associated with
processes that occur frequently in nature, of which the rates
of change of variables are significant, dynamic, determined
by various quantities that continuously change over time.
Thus, the study of population growth is a vast problem for
which many models can be constructed. In the work of J.
Murdy considered specifically tasks related to one species
and two interacting species,withapplicationstotheproblem
of pest control. Consideration of the model brings to thefore
the problem of identifying the entered parameters with the
data obtained from real biological experiments.
Environmental engineeringisundergoinga periodofintense
and profound transformation, encompassing both the
empirical and theoretical level of the studyof environmental
processes. In connection with the assessment of new
discoveries in environmental engineering, the formation of
theoretical concepts and the expansion of the scope of their
practical application, there is a need to put forward and
discuss common approaches to describing the processes of
information processing in environmental and technical
systems.
The complexity of information processing in technological
systems is determined, in particular, by their multi-level
structures. The application of a multi-level concept to the
description of information tasks poses the problem of
identifying the basic principles of constructing levels of
abstraction and the conditions for their effectiveinteraction.
The basic principles of building a conceptual level are as

solutions to the lower-level problems cannot be found, the
transition to the conceptual level will follow to clarify or
replace the formed problem, and also to develop new
restrictions on the search for lower-level solutions.

N. E. Bolshakov and V. A. Radkevich, studying the law of pest
migration inside the biotope, determined that the migration
rate is low, due to the small diffusion coefficient. Changes in

In the work of A. N. Goncharov and E. Ya.Elizarov, a
biocenosis consisting of one type of predator and several
types of prey is considered. It is noted that starting from a
certain level of prey concentration, the predator shows
selective activity. Assuming that - the time of the predator's
reprisal with one individual of the prey species, and-a
constant that characterizes the predator's viewing space
when hunting prey species, such that the value where the
concentration of the prey species at a time is the frequency
of encounters of the predator withthepreyspecies.Then the
rate of eating by the predator of the prey species.

B. G. Kovrov and O. A. Cherepanov studied the factors that
change species diversity, since a number of important
ecological principles are associated with diversity. They
obtained a mathematical model of the community,ifwetake
into account the reproduction of the population-the
population is limited by the substrate extracted from the
sources, its reproduction rate and the amount of food
extracted by one of its individuals from the source are

less than the number of prey populations per unit.

There are quite a few approaches to defining the concept of
ecosystem stability, stability in the corresponding
mathematical models of ecosystems, and comparing
ecosystems by this property. However, in the framework of
systems of differential equations of community dynamics,
the most universal, as before, is the definition of the stability
of the equilibrium point of the system. For example, for two
subsystems "predator-prey", conditions are found for the
parameters of the model, in which migration with different
intensities has a stabilizing effect, although it changes the
equilibrium values of the numbers. An exampleofa different
type of communication between systems is obtained if the
sets of isolated predator-prey pairs are combined by
introducing competition at the level of victims or at the level
of predators. Fluctuations in the neighborhood of the
equilibrium inherent in isolated pairs, and are saved when
you die systems, however, the oscillation frequency
decreases in the case of low-level concurrencyofvictimsand
increase in the case of a low competition level predators.
In modern sources, a mathematical model is consideredthat
expresses the balance of the population size:

The authors state that the birth rate and mortality are
assumed to depend on the mass of the individual or, more
precisely, on the deviation of the mass from some normal
value for the species under consideration. Therefore, the
equation (16) is added to the equation expressing the
dynamics of change in the mass of individuals:

The peculiarity of equations (17) and (18) is that the energy
balance of the population is considered as the main link in
the chain of environmental factors. The composition of the
main exchange includes, in particular, the power consumed
by organs and systems that are part of the oxygen transport
system. At the same time, the power consumed by the
oxygen transport system is a component of the main
exchange.
Currently, when studyingcomplexprocesses,itisconsidered
appropriate to use the principles of a systematicapproachto
problems. In a systematicapproach,all researchmethods are
integrated into a single process of environmental research,
which should be carried out within the framework of an
interdisciplinary research project.
For example, in the work of L. A. Akhmetov, E. V. Kornev and
T. Z. Sitshaev [13], the entire complex of energy-ecological
tasks in road transport is carried out on the basis of a
management system for rational energy consumption and
environmental protection activities. This system is the main
link of the road transport system from the standpoint of
environmental priority in relation to the systems of
commercial (CEA) and technical (TEA) operation of the car,
technical preparation of the car(TPA)andthesystem:driver

In modern scientific research, the principle of system
analysis is successfully applied in solving multicomponent
problems. The basis for solvingmulticomponentproblemsis
oriented graphs, and the basis for modeling them is pulse
processes. The essence of the pulse process is that a certain
change is set to a certain vertex.
Oriented graphs form the basis for solving multicomponent
problems, depending on the values on the arcs, which are
placed by experts or determined on the basis of statistical
information. Digraphs can be either signed or weighted.
The development of systems onthedigraphismodeledusing
pulse processes. The digraph can have positive or negative
feedback loops. The typeoffeedback determinesthestability
of the system: absolute or impulse. For the purpose of
linking to the time scale, time delays should be indicated on
the digraph arcs.
Multi-component tasks allow us to model predator-prey
ecosystems. The biological principles of ecosystem
sustainability are implemented in models not digraphs. The
conceptual representation of the equilibrium points can be
demonstrated using the eating and accumulation curves.
Large disturbances in the ecosystemandthetransitionofthe
system from one equilibrium state to another.
With the help of modeling multicomponent problems on
digraphs, it is possible to test the variants of the proposed
scientific hypotheses based on logical constructions thatare
sufficient to create a formalized mathematical model.
Ecosystem development is possible through a combination
of seven basic development curves.
The United Nations Economic Commission for Europe and
the Declaration on Low-Waste and Non-Waste Technology,
adopted in 1979 at the Meeting on Pan-European
Cooperation in the Field of Environmental Protection,define
low-waste and non-waste technology as the practical
application of knowledge, methods and tools in order to
ensure the most rational use of natural resources and
protect the environment within the framework of human
needs. It follows that low-waste technology solves a two-
pronged problem: the effective use of natural raw materials
and products of their processing, on the one hand, and the
protection of the environment from various types of
pollution and waste, on the other.
The goal of developing low-waste and resource-saving
technologies is to create closed technological cycleswithfull
use of incoming raw materials and waste. This is an attempt
to reproduce natural cycles, since the biosphere is a closed
system, where all the elements areinterconnectedandcause
each other. The modern man-made economy, including the
ATC, is an open system, where obtaining a relatively small
final product requires huge resourcesandisaccompanied by
large waste .
The gradual transformation of traditional technologies into
low-waste and resource-saving ones will allow for a gradual
transition from open production systems with free input of
resources and waste output to semi-open ones with partial
use of recoverable materials and waste treatment, and then
to closed-type systems with complete processing and
disposal of all incoming resources and waste and the
cessation of environmental pollution by the latter.
Thus, in natural, natural ecological systems, the acquisition
of resources and disposal of waste occur within the cycle of
all elements.
In most scientific and technical studies, the PBX is
considered as an object that influences the formation of
environmental indicators of the ATC. The processes of
energy and mass transformations between the PBX and the
environment occur the entire lifecycle and are associated
with the consumption in the relevant processes fuel, oil,
other types of operating materials, energy, accompanied by
pollution with harmful substances.
In [3], the total consumption of materialsfortheoperationof
the PBX is treated by processing an array of information,
which allows us to establish reliable dependencies of the

CONCLUSION
The greatest influence on fuel consumption is exerted bythe
indicator efficiency, which characterizes the efficiencyofthe
actual cycle and is determined by the ratio of the indicator
work to the heat spent on obtaining this work. In contrast to
the thermal efficiency, the indicator takes into account not
only the heat removal to the cold source, but also other
losses associated with incompleteness of combustion and
dissociations; leakage of the working fluid through non-
densities and heat removal with exhaust gases.
Thus, for sufficiently large quantities of non-discrete
quantities, despite their simplified properties, deterministic
mathematical models, within the limits of some reliability of
the results, are in good agreement with the studied
ecological processes.
