Abstract:

The relevance of the topic is driven by the rapid development of digital technologies and the implementation of automated systems in various aspects of life, including the administrative sphere. The aim of the article is to investigate and analyze the procedure for considering and resolving administrative cases in automatic mode according to the Law of Ukraine "On Administrative Procedure". Achieving this goal became possible through the use of a comprehensive set of scientific methods, including legislative analysis, comparative analysis of foreign experience, and legal analysis of the provisions of the law. The key provisions of the Law of Ukraine "On Administrative Procedure" related to the automatic mode of considering administrative cases have been examined. It is noted that the law requires amendments to specify the use of automation, establish legal frameworks for this method of resolving administrative cases, and provide clear legal regulation of aspects such as the legal stability of automatically adopted administrative acts, rights, and obligations of citizens in this context. It is established that defining the responsibilities of administrative bodies in providing information and clarification to individuals about the automatic mode is a crucial aspect for safeguarding citizens’ rights. Emphasis is placed on the necessity for further legislative improvements to consider aspects of legal definiteness, protection of individuals’ rights, and the neutrality of decisions, ensuring fairness in the resolution of administrative cases in automatic mode. Conclusions and recommendations for further improvements in legislation and the practice of handling administrative cases in automatic mode have been formulated based on the conducted research. Prospects for further research include an extended analysis of the effectiveness of implementing automated systems in the field of public administration.

Abstract:

The accurate labeling of species and size of specimens plays a pivotal role in fish auctions conducted at fishing ports. These labels, among other relevant information, serve as determinants of the objectivity of the auction preparation process, underscoring the indispensable nature of a reliable labeling system. Historically, this task has relied on manual processes, rendering it vulnerable to subjective interpretations by the involved personnel, therefore compromising the value of the merchandise. Consequently, the digitization and implementation of an automated labeling system are proposed as a viable solution to this ongoing challenge. This study presents an automatic system for labeling species and size, leveraging pre-trained convolutional neural networks. Specifically, the performance of VGG16, EfficientNetV2L, Xception, and ResNet152V2 networks is thoroughly examined, incorporating data augmentation techniques and fine-tuning strategies. The experimental findings demonstrate that for species classification, the EfficientNetV2L network excels as the most proficient model, achieving an average F-Score of 0.932 in its automatic mode and an average F-Score of 0.976 in its semi-automatic mode. Concerning size classification, a semi-automatic model is introduced, where the Xception network emerges as the superior model, achieving an average F-Score of 0.949.

Abstract:

This scientific article proposes a model of pedestrian and car flow control system that can characterize the operation of two different control modes, the first of which is fully automatic, and the second works in automated mode, the results of which depend on information about the current situation on the road. the number of pedestrians and cars or depends on the intensity of traffic. In order to demonstrate the work of the proposed model, we will take some sections of the direct road where there is an adjustable pedestrian crossing. The system can determine the number of pedestrians in two ways: through surveillance cameras and with available statistics, such as information about the intensity at specific times. The second method, namely the application of pre-known parameters such as the intensity of pedestrian and traffic flows is used when it is impossible to determine the current situation on the road due to some reasons such as accident, bad weather and so on. The modes will be switched using the functionwhich will determine the mode of regulation of traffic lights according to the time intervals at which the intensity of the flows will also change. The automatic control system will work during rush hour, when the city's transport network operates. the greatest load. The second mode is for certain periods of time when the intensity of pedestrian flow is low, for example at night. The relationship between these intensity and time will be established statistically. The mode of automatic or "hard" regulation determines the duration of the pedestrian and car phases of traffic lights depending on the number of pedestrians and cars. If it is impossible to determine the number of road users using video cameras, then we calculate due to the intensity of traffic flows, and the automated control mode, ie "call" calculates the duration of the delay between two calls and the duration of the pedestrian phase. crowds and traffic near regulated pedestrian crossings.

Abstract:

Automatic guided vehicles (AGVs) in the horizontal area play a crucial role in determining the operational efficiency of automated container terminals (ACTs). To improve the operational efficiency of an ACT, it is essential to decrease the impact of battery capacity limitations on AGV scheduling. To address this problem, this paper introduces battery swapping and opportunity charging modes into the AGV system and proposes a new AGV scheduling problem considering the hybrid mode. Firstly, this study describes the AGV scheduling problem of the automated container terminals considering both loading and unloading tasks under the hybrid mode of battery swapping and charging. Thereafter, a mixed-integer programming model is established to minimize the sum of energy costs and delay costs. Secondly, an effective adaptive large neighborhood search algorithm is proposed to solve the problem, in which the initial solution construction, destroy operators, and repair operators are designed according to the hybrid mode. Finally, numerical experiments are conducted to analyze the effectiveness of the model and the optimization performance of the algorithm. The results demonstrate that the hybrid mode of battery swapping and charging can effectively reduce the number of battery swapping times and scheduling costs compared to the existing mode.

Abstract:

The use of natural gas in the heat treatment of feed reduces the cost of livestock products and increases competitiveness in the foreign market. An analysis of various modifications of gas-using digesters with a wide range of performance and design, offered by the foreign market, showed that their common disadvantage is the lack of automatic gas flow control in proportion to the heat flow used to heat the feed to boiling and during boiling. An energy-saving fodder boiler with an automatic gas flow control system in proportion to the consumed heat flow has been developed. The studies were carried out on an experimental sample of a feed boiler, in which an automated gas flow control system based on semiconductor thermoelectric elements acts on the actuator without intermediate output signal amplifiers. The efficiency of the automated energy supply system was studied by experimental studies of the dynamics of gas consumption in the process of thermal processing of feed in automatic and manual modes. It was found that the total gas consumption for the preparation of 100 kg of feed in automatic mode with gas flow control proportional to the consumed heat flow is 1.2 times less than when the boiler is in manual mode. The most optimal mode for saving fuel is provided when setting the gas burner in the initial period of heating up to a power of 14 kW for a digester with a volume of 100 liters. Gas overrun up to 20% occurs for boilers with more powerful gas burners (22 kW).

Abstract:

The development of machine learning algorithms based on semi-industrial thermal benches will approach the development of an automated system capable of detecting and tweaking energy-efficient and environmentally friendly combustion modes in large power plants and increasing their efficiency without significant changes in the design of boiler equipment. Determination of combustion modes and optimisation of the combustion process based on neural network analysis of visualisation patterns of the coal flame in the boiler. Determining the combustion mode in the furnace space and superimposing (automatically adjusting) the parameters based on sensor readings to bring it to the optimum mode and maintain stable combustion is a complex task. Currently, the selection of necessary parameters is done by operator-assisted automatic process control systems, but this process is based on known design parameters and is not always efficient or environmentally friendly in practice. This problem can be solved by determining the combustion mode in the furnace space using modern machine learning methods and automatic parameter optimisation in a continuous mode article.

Abstract:

In current freight railroad operations, locomotive control is shared between the human engineer and automated energy management systems such as GE Trip Optimizer. Transitions between the manual and automatic modes temporarily increase engineer workload above the demands of the current operating situation. Using the average response time and average number of secondary visual attention task stimuli presented as proxy measures of workload, we tracked the time course of workload during the mode transitions for two types of automated control system. The average response times peaked immediately after the mode change. The average number of stimuli presented peaked just before the mode change. We conclude that this technique of measuring workload would be very useful in evaluating future automated systems concepts in a train simulator.

Abstract:

Abstract To solve the problem of excessive fluctuation of the V2G load of the electric vehicle charging pile, this paper proposes an automatic control algorithm for the V2G frequency response mode of the electric vehicle charging pile. The FPGA is used as the core processing unit to collect and process the V2G frequency data of the charging pile; the multiple linear regression model is used to predict the charging and discharging loads, and the automated two-layer control model is established; the sparrow search algorithm is used to optimize the weights and thresholds of the BP neural network to realize the control of the V2G frequency response mode. The experimental results show that the load prediction error of this method is small. After the automatic control, the load fluctuation of the charging pile is small, and the electric vehicle charging pile’s V2G frequency response control effect is better.

Abstract:

This paper describes a novel rate and rate-integrating mode-switchable axisymmetric gyroscope. A precession angle tracking algorithm is developed to enable the gyro to switch automatically between rate and rate-integrating modes at preset rate points through a digital control system within the gyro. We also propose a vibrating amplitude control method for the rate-integrating mode that directly extracts the angular rate output to ensure switching stability. In rate mode, the bias instability and angle random walk of the gyro reach 0.106°/h and 0.011°/√h, respectively. Additionally, an input range of over ±5000°/s is measured in rate-integrating mode. The scale factor nonlinearity reaches approximately 116 ppm over the full-scale range. The control system implements effective steering control of the gyroscope, with a switching delay of 10 ms from rate mode to rate-integrating mode and 100 ms from rate-integrating to rate mode. The proposed system actualizes a new type of gyroscope with high accuracy and a wide input range, which combines the benefits of rate and rate-integrating modes.

Abstract:

Objective. Synthesis of an automatic control system for the process of separation of an oil and gas mixture based on a mathematical model describing the process in terms of “input-output”. Methods. The study uses the method of material balance analysis, which allows for determining the flow rate of material flows (oil, gas, and water) at the separator outlet based on the known flow rate of the oil and gas mixture at the inlet and the introduced separation coefficients. Results. Mathematical dependences describing the separation process based on the material balance were obtained. A mathematical model of separator statics was developed, which is the basis for further development of a model of separation process dynamics and synthesis of an automatic control system. Scientific novelty. The proposed mathematical model allows for determining the flow rates of material flows of the separator, taking into account the oil and gas separation coefficients and the oil dehydration coefficient, which is important for further automatic control of the process. Practical significance. The developed model can be used to synthesize an efficient automatic control system for a three-phase separator, which will improve the quality of oil, gas, and water separation and contribute to the optimization of the technological process. Keywords: oil and gas mixture, three-phase separator, statics, mathematical model, separation coefficients.

A function-failure correlation model witha standard description is adopted to describe the relationship between failuremodes and functions, so that designers and engineers from different fields cancomprehend and communicate within the same framework. Functional flows andfailure modes are defined as basic concepts in the fuzzy cognitive map, whichprovides an easy way to carry out an automatic cause and effect reasoning.

Abstract:

Dynamic model-updating methods are a useful tool for obtaining high-precision finite element (FE) models. However, when using such methods to update a model, there will be problems with incompleteness and mode switching. To overcome these problems, this paper proposes a structural dynamic model-updating with an automatic mode-identification method. In this method, a mode-identification index is established based on image-similarity recognition to identify the consistency between FE and experimental mode shapes, and particle swarm optimization is introduced to update the model. In addition, to reduce the computational time, Latin hypercube sampling is employed to perform probability statistics of the switching range of the concerned mode orders, and the orders of mode identification are reduced according to the statistics results. In this paper, the proposed method was validated by model-updating of a square plate. The natural frequencies and mode shapes of the plate were obtained by experimental modal analysis and used as the updating objectives of the FE model. In addition, the boundary condition of the plate was simplified by a series of springs, which were used as updating parameters along with material properties and dimensions. Finally, the FE model of the plate was updated by the present method, and the results indicate that the objective function error of the updated FE model was successfully reduced from 14.31% to 1.05%, which proves that the proposed model-updating method is effective and feasible.

Abstract:

The image-guided system is the important issue for the automatic navigation. In this paper, a novel visually-guided disaster detection Robot (DD robot) is designed to carry out the automatic navigation function. Moreover, the DD robot is meticulously designed to detect gases or suspicious persons in the surrounding environment of the plant. Besides, we have successfully made our robots equipped with the devices by ourselves. These devices contain the disaster-detected sensors, the navigation module and the image module. In addition, we designed three operation modes: Automatic navigation mode (AN), Manual Remote Control mode (MRC) and the Visually-Guided mode (VG). Furthermore, the human-machine interface offers the users the view of information and also the details of the functions of the DD robot. The experimental results validate the practicality of the proposed visually-guided based automatic navigation system applied to disaster detection robots.

Abstract:

In this work the question of creation and application of formal models in the form of varieties of Petri nets to process of the automated electric tests of the automatic spacecraft is considered. At present, automatic spacecraft for various purposes are required to have a long active life. This implies the use of modern electronic components that are resistant to external factors affecting outer space. Electronic equipment, consisting of these components, forms information networks on Board the spasecraft, which leads to the need for a comprehensive electrical inspection of the operation of onboard instruments and systems of such networks in an automated mode. Modeling of the processes taking place in the on-Board electronic units, and the control and verification equipment interacting with it, is of separate interest, as it allows to develop automated testing methods based on the obtained data of the model analysis.

Abstract:

Automated, precise single particle manipulation in the microscale is in great demand and is one of the great challenges in biomedical and biochemical engineering. Automatic micromanipulation has also become a microrobotics challenge. Following this challenge, control technology is integrated with dielectrophoresis (DEP)-based micromanipulation technology in this paper to construct automatic DEP-based micromanipulation systems. DEP micromanipulation systems with electrodes of quadrupole polynomial geometry are developed as controllable microactuators. A semianalytical modelling method is proposed to formulate the analytical models of the DEP manipulation systems, which manifests that the DEP manipulation systems are non-affine non-linear systems. Then, taking the parameter uncertainties, unmodelled dynamics and external disturbances into account, an adaptive law combined with a dynamic sliding mode controller is designed for two-dimensional trajectory tracking control of a DEP micromanipulation system. The closed-loop system is proved stable in the presence of bounded lumped uncertainty based on the Lyapunov theorem. Finally, simulation results show the validity of the proposed control design.

Abstract:

ABSTRACT Automatic production management (APM) is a tool that assists in the operations of agricultural tractors, increasing yield and energy efficiency. The objective of the experiment was to compare the energy and operational performance of a 373-kW articulated tractor equipped with APM and manual mode of engine transmission and rotation, across different real-world speeds. The experiment was conducted in a randomized block design with five replicates, using a split-plot arrangement with two system modes (manual and automatic) in the plots and four real-world speeds (4, 6, 8, and 10 km h-1) in the subplots, totaling 40 experimental units. The evaluated variables were: wheel slippage; engine rotation; hourly and specific fuel consumptions; drawbar force, power, and yield; operating speed; and engine thermal efficiency. The variance of the data was analyzed using Tukey’s test for the first factor, and regression analysis for the second factor and interactions. The automatic mode showed lower engine rotation and wheel slippage without compromising the other variables. The use of this mode showed energy advantages at 4 and 6 km h-1 by resulting in less fuel consumption per hour. In addition, the manual mode presented higher thermal efficiency at lower speeds than the automatic mode, which showed a linear increase.

Abstract:

Automatic sectionalizing and redundancy of power transmission lines is one of the conditions for network intellectualization and can significantly reduce the power supply interruption time for rural consumers. However, both sectionalizing and redundancy of power transmission lines in 0.4 kV electric networks are used extremely limitedly since there are no sufficiently effective methods and technical means for their implementation. This article presents a method to automatically deactivate the automatic load transfer switch when restoring the normal network operation mode. The paper considers the implementation of the method on the example of damage occurring in the network where power is supplied to consumers from two power sources using an automatic load transfer switch and two sectionalizing units. A device is developed which allows implementing the developed method of automatic load transfer switch deactivation. The device consists of sectionalizing unit, automatic load transfer switch, voltage presence sensor, power direction sensor, memory element, repeater element, element AND and 3 elements NOT. The work of the device is described. The proposed method for automatically disconnecting the automatic load transfer switch in order to return the consumers’ power supply circuit to its initial state solves the problem of eliminating unreasonable power supply interruptions for consumers.

Abstract An automatically mode-locked fiber laser based on the nonlinear polarization rotation(NPR) effect was demonstrated and a stable mode-locked pulse train was obtained. A model of parameters such as transmittance, self-phase modulation and self-amplitude modulation of the NPR mode-locked fiber laser was established. The relationship between the equivalent saturable absorption effect and the rotation angles of the waveplates was analyzed. Using that, an automatic mode-locked fiber laser based on NPR method and hill-climbing algorithm was built, and the mode-locked output could be obtained. Output characteristics were discussed also.

One of the main ways to increase the rotary excavator productivity is to automate excavator operation. The article presents an automatic speed adjustment system for the stacking conveyor belt of a trench rotary excavator. It is shown that the automated control system will allow taking into account the rotor actual rotation speed and the bucket fill factor, processing data and solving tasks of the excavator operation automatic control in excavation mode. The represented automated control system will ensure the conveyor operation with the necessary, but not maximum speed. Therefore, the conveyor will not work “in vain”, that, in its turn, will reduce operating costs including energy.

IR sensor is used to avoid the obstacles and change left direction after right direction and it is mounted at the front side of the robot. It is applied to meet the U turn movement for complete coverage navigation by using optocoupler based encoder feedback. In this system, two motors 555 dc gear motor are used with L298 for robot movement, and other 12V dc motor is used with MOSFET driver to control the speed of the cleaner. The wireless connection between remote control and robot is established by using RF module. In U paths, the robot moves forward direction and turn left if it is detected wall and turn left again and move forward direction. Battery percentage, cleaner speed, movement of the robot and selected mode are displayed on the LCD. ATmega328P microcontroller based Arduino UNO board are applied as the heart of the system. Simulation test and experimental test are utilized for stable response in domestic application.

Abstract:

Dynamic analysis models are customarily employed in turbomachinery design to predict critical whirling speeds and estimate dynamic response due to loads imposed by unbalance, misalignment, maneuvers, etc., Traditionally these models have been assembled from beam elements and been analyzed by transfer matrix methods. Recently there has been an upsurge of interest in the development of improved dynamic models making use of finite element analysis and/or component mode synthesis. We are currently developing a procedure for modelling and analyzing multi-rotor systems [1] which employs component mode synthesis applied to rotor and stator substructures. A novel feature of our procedure is a program for the automatic generation of the component modes for substructures modelled as Timoshenko beam elements connected to other substructures by bearings, couplings, and localized structural joints. The component modes for such substructures consist of constraint modes and internal modes. The former are static deflection shapes resulting from removing the constraints one at a time and imposing unit deflections at the constraint locations. The latter have traditionally been taken to be a subset of the natural modes of free vibration of the substructure with all constraints imposed. It has however been pointed out [2] that any independent set of geometrically admissible modes may be used. We take advantage of this and employ static deflections under systematically selected loading patterns as internal modes. All component modes are thus obtained as static deflections of a simplified beam model which has the same span and same constraints as the actual substructure but which has piecewise uniform dynamic properties. With the loading patterns we employ, all modes are represented by fourth order polynomials with piecewise constant coefficients. We have developed an algorithm for the automatic calculation of these coefficients based on exact integration of the Timoshenko beam equation using singularity functions. The procedure is illustrated by applying it to a simplified system with a single rotor structure and a single stator structure. The accuracy of the procedure is examined by comparing its results with an exact analytical solution and with a component mode synthesis using true eigenfunctions as internal modes.

Abstract:

This article presents our work toward correct and efficient automatic differentiation of OpenMP parallel worksharing loops in forward and reverse mode. Automatic differentiation is a method to obtain gradients of numerical programs, which are crucial in optimization, uncertainty quantification, and machine learning. The computational cost to compute gradients is a common bottleneck in practice. For applications that are parallelized for multicore CPUs or GPUs using OpenMP, one also wishes to compute the gradients in parallel. We propose a framework to reason about the correctness of the generated derivative code, from which we justify our OpenMP extension to the differentiation model. We implement this model in the automatic differentiation tool Tapenade and present test cases that are differentiated following our extended differentiation procedure. Performance of the generated derivative programs in forward and reverse mode is better than sequential, although our reverse mode often scales worse than the input programs.
