Distributed Model Reference Adaptive Control Based on Cooperative Observer with Optimal Control Modification for Synchronization of Heterogeneous Vehicle Platoon
Authors: Prayitno Agung , Indrawati Veronica , Nilkhamhang Itthisek
Published: January 2023

Many distributed controllers for vehicle platoon are designed based on homogeneous assumption and full state information. In reality, vehicle platoon may consist of heterogeneous vehicles and may have limited information due to sensor constraints. Therefore, this paper proposes a distributed model reference adaptive control based on cooperative observer for a heterogeneous vehicle platoon with limited output information and subjected to uncertain dynamics. Cooperative observer provides a full state estimation of the system. Each follower has a reference model that is designed based on its nominal model and cooperative state variable feedback. Main control system is composed of (i) nominal control that utilized the cooperative state estimation tracking error and (ii) adaptive term that adopted an optimal control modification as an adaptation law. The tracking error of followers to the reference model is shown uniformly bounded and the stability of the platoon is guaranteed through detailed analysis. Performance of the proposed controller is verified by using numerical simulation. To show the advantage of the proposed control, simulation results are compared to the standard distributed model reference adaptive control that is applied for heterogeneous vehicle platoon. It is shown that the proposed control eliminated the high frequency oscillation in the control input.

Published: January 2023

Conducting extensive, time-consuming analysis campaigns is a typical technique to better understand and manage surface water quality. These usually generate a substantial amount of data that is challenging to comprehend. Principal component analysis may be advantageous for such a project (PCA). From the perspective of such an application, eight physico-chemical parameters are important: Sodium (Na+), Bicarbonate (HCO3-), Magnesium (Mg2+), Total Alkalinity (as CaCO3), Chlorides (Cl-), Potassium (K+), Calcium (Ca2+), Sulfates (SO42-), coming from the analysis of 100 water samples collected between February 2014 and December 2015 on 25 stations distributed on Inaouen catchment areas, were analyzed. The principal component analysis applied to the data showed that the variables could be grouped into two principal components. The interpretation of the results using these tools allowed us to understand that the parameters responsible for water quality are related to component Dim1 (HCO3-, CaCO3, K+, Cl-, Na+ and SO42-) and component Dim2 to the processes associated to (Ca2+ and Mg2+) for the physicochemical parameters, the Dim1 factorial design accounts for 67.80% of the variance; it is expressed towards its positive pole by HCO3-, CaCO3, K+, Cl-, Na+ and SO42-, which present good correlations between them. However, the Dim2 factorial plane represents only 17.60%, defined by the Ca2+ and Mg2+ ions towards its positive pole. The Dim1XDim2 plane's typological structure reveals the individualization of three different groupings based on their hydrochemical quality. A feasible reduction in the number of dimensions without a major loss of information was discovered by the PCA. This tool is a good choice from the standpoint of developing management tools.

Published: January 2023

This article explains about a stage after the stage of the verification test, there is a phase of a form of prior activity to the final stage, i.e., the hot commissioning phase. Hot commissioning is a stage for providing a realistic condition or validation test activity. Based on the follow-up activity which is the reason for choosing the title, therefore the two research objectives in this article are set. The first objective is to create conditions for the system when the end user controls through the radio-based electronic device, whereas the second objective is to create conditions for the system when the end user controls through the telephony-based electronic device. The steps of research methods for achieving the research objectives are carried out through (i) calling activities, (ii) connecting process, and (iii) disconnecting activities after obtaining a connection to communicate from a radio-based device (using the handy talky, HT) and from the telephony-based device (used the mobile phone). The two results based on research objectives have been obtained after observation regarding activities of calling activity, making telephone calls, and termination activity after connecting from radio-based and telephony-based devices. Based on the research results, it can be concluded that the half duplex-based interface device for communicating (IDC) functioned after the realistic conditions is given.

Published: January 2023

The article is devoted to the issues of the features of computer structural modeling of bio- and physiological systems of the human body. It has been established that most of the elements of a living organism and biological processes occurring in them are formalized using integral-differential equations of higher orders, the analytical solution of which is difficult. As modeling components of biotechnical systems and complexes, it is proposed to use circuitry implementation of a wide class of functional solvers based on functional circuits of operational amplifiers, which makes it possible to observe and study the dynamics of parameters of a biological object and bioprocesses in the visual modeling environment in the form of their mathematical models in real time.
Algorithms for the Formation of Recommendations in the Information System
Authors: Sineglazov Victor , Oliinuk Yuriy
Published: January 2023

The article deals with the problem of scalability and dimension reduction of data in the algorithms of recommendations. It is proposed to improve the item-to-item algorithm by excluding from the user-item matrix elements that that do not have enough estimates. Thus more denser data are used that allows to receive more exact results. Also due to the fact that the dimension of the user-item matrix decreases, the execution time of the algorithm decreases. To solve the problem, the Tachimoto coefficient, the cosine measure, the Pearson correlation coefficient and the Euclidean distance are used to calculate the degree of similarity of the elements. The efficiency of the usual item-to-item algorithm and the algorithm were compared using only the active values in the user-item matrix. The obtained results confirm the efficiency of the item-to-item algorithm based on a dense matrix. The obtained results can be used to optimize the operation of any recommendation system.

Published: January 2023

The theoretical foundations of testing antenna parameters and characteristics in the far radiation field are presented. A two-beam model of radio wave propagation was used, including a direct wave and a wave reflected from the earth's surface. This model meets the conditions for carrying out measurements on a signals training areas or in an anechoic chamber. It is shown that for a given distance between the antennas, it is necessary to control the dimensions of the aperture  transmitting and receiving antennas for the compliance with the maximum permissible values. Formulas for determining the permissible dimensions of the antenna aperture are obtained. The influence of the antenna hanging heights on the measurement accuracy was also investigated. Recommendations for reducing the level of electromagnetic waves reflected from the earth's surface are given.

Authors: Churina Alexandra
Published: January 2023

This article deals with the search for a palliative optimal solution to the optimization of the electric power problem. A mathematical model of planning by the development of a hierarchical ergatic electric power system is proposed to be presented as an optimization problem of minimizing vectors. An innovative direction in modeling the control system of an ergatic electric power system based on artificial neural networks is also considered. It is noted that intelligent control systems for power supply systems are robust. The innovative concept of a smart power system is due to the integration into a hierarchical power system of renewable energy sources based on modern computer technologies. It is noted that during the operation of an intelligent electric power system, control systems must provide adaptive qualities in relation to the topology of the power supply system. It is proposed to investigate the solution to the optimization of electric power problems using methods of fuzzy mathematical programming.

Published: January 2023

The article will be intended to explain the Image Depth Detection System, which in turn should perform all the necessary functions for detecting objects on a 3D scene, obtaining information about the sizes of bodies, and determining distances to certain bodies. Since such systems already exist in the modern world, the main goal was to create a model that meets the requirements regarding price-quality, since systems of this type currently on the market have a high cost price. Also, the improvement of the method of determining the depth of the image in this system was created thanks to the analysis of filtering methods available in the Matlab environment. An analysis of operation in different conditions of use, i.e. in the presence of external disturbances, such as daylight on the street, has been created.

Published: January 2023

The shallow groundwater has a direct and indirect effect on natural vegetation and agricultural production. The decline in groundwater level (GWL) can have negative impacts. In many areas in Hungary decreasing GWL trends in the last decades were found by earlier studies. In our research we studied the characteristics of groundwater level focusing on our study area, the subbasin of Szarvas-Békésszentandrás Oxbow. We analysed 20 years daily data of groundwater level of eight monitoring wells. Annual course and long term tendencies of groundwater level were examined. In average of 16 years the GWL reaches its maximum in April and its deepest level in autumn (September, October and November depending on the station). Four typical groups of groundwater level courses could be distinguished based on the average depth and seasonal variations of GWL. The year to year GWL variability is larger in January and April compared to July and especially to October. The trends of the middle months of the seasons are almost the same in significance and slope compared to the trends based on yearly mean time series. The differences in trends can be found between stations rather than between the months used for calculations. The larger part of the subbasin can be characterised by decreasing trend in groundwater levels (2002-2020). The change exceeds 1 m at station Szarvas 2832 (144 cm) and Szarvas 2778 (122 cm). However, there is a station with no significant trend, GWL at Csabacsűd 2779 station shows relative stability in yearly average, which is valid for some areas in the eastern part of the subbasin.

Published: January 2023

Aerobic rice production is an alternative growing method to reduce water consumption of rice and thus increase the water productivity of the system without a significant reduction of yield and quality. Evapotranspiration (ETc) of a Hungarian rice variety, ‘SZV Tünde’ under aerobic conditions was measured in large weighing lysimeter during the growing season in 2020. In our experiment, 506.7 g/m2 grain yield and a total above-ground biomass of 1140.4 g/m2 were produced with the application of 315.6 mm of irrigation. Water use-efficiency (WUE) based on the water input and the grain yield was 0.65 g/L. Total ETc for the whole season was measured as 648.3 mm. However, ETc values were ranged 2.04-3.86 mm/day, 3.57-7.90 mm/day and 0.90-4.26 mm/day at the initial, mid and end stages, respectively. Crop coefficients for the different periods of the season were calculated as Kcini=0.82, Kcmid=1.40 and Kcend=0.77. Negative effects of drought can seriously damage rice crop; therefore irrigation scheduling has significant role in successful aerobic rice cultivation. Reliable estimation of evapotranspiration rate in different crop developmental stages can promote this goal.
Rheological Performance of ZycoTherm/Nano-Silica Composite Modified Binders at High and Low Temperatures
Authors: ALI Shaban Ismael Albrka , ALOTHMAN Dania , GÖKÇEKUŞ Hüseyin
Published: January 2023

This study aims to investigate the impact of control and warm mix binders modified with nano-silica on the asphalt binder functioning to resist rutting endurance and low-temperature cracking. The percentages of nano-silica employed in this research were 2%, 4%, and 6% of asphalt binder weight. The control and modified binders were evaluated by performing conventional and rheological tests. The rheological properties were examined by master curves, isochronal plots, multiple stress creep recovery (MSCR), Superpave rutting parameter, and bending beam rheometer. The outcomes implied that the performance of the asphalt binder (with or without ZycoTherm) improved when nano-silica was added concerning (G*/sin δ) parameter. The MSCR test demonstrated that the recovery (R %) of the control and warm mix binders improved whereas the non-recoverable creep compliance (Jnr) dropped, implying that nano-silica boosted the rutting potential. Moreover, it was observed at different temperatures that the values for the complex shear modulus increased when the phase angle values were reduced. Furthermore, at low temperatures, it is presumed that the performance of nano-silica modified asphalt binders will have minimal performance as opposed to the binders prepared with ZycoTherm, which prevents low-temperature cracking.

Published: January 2023

La Escuela Moderna de Francisco Ferrer Guardia fue una experiencia que, desde Barcelona, pretendió difundir una cultura emancipadora a nivel local y mundial. Una concienzuda etnografía virtual con fuentes de alto nivel académico, que incluyen tesis doctorales de los últimos años, nos permite conocer cómo las ideas de la enseñanza racionalista que promulgaba penetraron en Latinoamérica pese a la diversidad de países y contextos concretos. Una cultura en oposición a la hegemónica fue posible, no obstante que algunos de los postulados de Ferrer Guardia siguen viéndose como lejanos.

Objectives: Laryngeal squamous cell carcinomas (LSCC) is one of the most common aggressive neoplasms of the head and neck region. There is a significant need for identification of successful and accurate prognostic markers to better estimate the clinical outcomes for LSCC patients. In this study, we aimed at analyzing the differential expressions of inhibitor growth (ING) family members and to evaluate the prognostic values of deregulated ING genes in LSCC.
Methods: We investigated the relative expressions of ING genes in laryngeal tumor-normal tissue pairs in the mRNA level using quantitative real-time polymerase chain reaction and relative expression of ING3 in the protein level using Western Blot analysis.
Results: The rate of genetic alterations of ING3 was relatively higher in head and neck cancer including LSCC. ING3 expression was significantly upregulated in LSCC tissue samples in both mRNA and protein level. Higher expression of ING3 was also correlated with poor disease-free survival of patients with head and neck cancer.
Conclusions: Our findings assigned an oncogenic feature for ING3 in laryngeal cancer with a significant upregulation detected in advanced cases and suggested a vital prognostic potential for ING3.
Chemical Methods for Revealing Latent Fingerprints on Wooden Surfaces and in their Mass
Authors: Ceobanu Andrei
Published: January 2023

Fingerprints are used since 19th century by Police forces to identify criminals and murderers. In 20th century the evolution of science contributed to develop forensic methods for revealing latent fingerprints. One of the most used chemical method for revealing latent fingerprints on documents and paper objects is made by using Ninhydrin. This substance has great results but is affecting the characteristics of ink or other scriptural substances.
In 21st century, scientists developed a new method in this field using a new discovered substance named Indandione. The new substance is more used by forensic scientists than Ninhydrin. Forensic literature has not documented the results of Ninhydrin applied on wooden surfaces. Using Ninhydrin on these surfaces, natural wood which has not applied varnish film, forensic scientists or specialists will have surprising results. On wood surfaces without varnish film, Ninhydrin acts like on the paper but the time interval from applying Ninhydrin and revealing fingerprints is longer, about one week, with daily treatments.
Treatment with Ninhydrin on wooden surfaces was not too documented by forensic scientists because, in developed countries, murders committed using wooden instruments has a small rate. In my country, majority of murders are committed in rural communities where the level of education is commonly low and people are using this kind of weapons to commit crimes (axes, pitchforks, etc.). By using Ninhydrin I achieved an identification of a murderer. This method can be successfully developed and use in forensics.

Immigration Detention, Deportation and Judicial Review in the Age of Covid 19
Authors: Akhtar Zia
Published: January 2023

The first significant issue arising out of the COVID-19 pandemic for migrants who have been refused stay to come before the Administrative Court has been the question of the continued legality of immigration detention in the face of the risks and practical difficulties arising from the crisis. The pandemic raises two vital issues affecting the legality of immigration detention; on the one hand, that detainees may invite an increased risk of infection by reason of the “congregate” setting of detention centres, and on the other that removals in the short term will not be possible and that the probability of removal is uncertain even in the medium term. The issue is if the Home Office policy is  “irrational and discriminatory” in its approach, which has led to inconsistencies in how the detention cases are handled. This paper enquires if the merit based judicial review can expedite the cases where administrative detention is concerned in circumstances of medical emergency. The argument here is that the Home Office should give full credence to the medical impact of detention to act in accordance with the Hardial Singh principles and by keeping in perspective the pandemic and the BMA reports of the unreasonableness of detention before deportation.

Published: January 2023

Background: Traumatic brain injury (TBI) is one of leading causes of death among young people worldwide. Chloroquine, an antimalarial drug, has been shown to easily cross the blood-brain barrier (BBB) and inhibit autophagy in a variety of disorders, including Alzheimer disease and brain ischemia. We investigated the effects of chloroquine on neuronal protection after induction of brain trauma in male rats.Methods: A total of 120 male Wistar rats were treated with chloroquine at doses of 1.5, 3, and 6 mg/kg intraperitoneally after induction of diffuse TBIs. The veterinary coma scale was used to assess short-term neurological deficits. BBB disruption was evaluated using the Evans Blue dye method 6-hour post-injury. Vestibulomotor function was evaluated using the beam walk and beam balance methods. Histopathological changes in the brain tissue in different groups were evaluated using light microscopy and hematoxylin-eosin staining. Brain water and cerebrospinal fluid (CSF) contents of matrix metalloproteinase 9 (MMP-9) were assessed using the wet/dry method and enzyme-linked immunosorbent assay, respectively.Results: The results showed that injecting chloroquine (3 and 6 mg/kg) 30 minutes after TBI significantly reduced brain edema and BBB disruption, and recovered neurological deficits post-TBI (P<0.01). Furthermore, CSF MMP-9 was significantly reduced after administration of 1.5 mg/kg chloroquine (P<0.01).Conclusion: Chloroquine has neuroprotective effects in the brain, and thus, has the potential to mitigate the effects of brain trauma. It is possible that the anti-inflammatory and neurogenic effects of chloroquine are due to a decrease in MMP secretion in the CSF.

Published: January 2023

Purpose: To consider the issue on performance of operational control of deformations of tunnel bottomhole zone with the use of ground-based laser scanning technology when tunneling with New Austrian tunneling method which is the most progressive one and feasible in economics terms for underground building construction by mining. The essence of this method is in that as a support for tunnel bottom-hole zone, a self-supporting shell made of sprayed concrete without traditional fastening method usage is applied that allows to save time for tunneling significantly, especially of those tunnels which have complex geometry and non-standard dimensions. At the same, the conceptual basis for this method is the necessity to identify operatively bottomhole zone soil mass deformations that’s justified by the need to provide job realization safety. Methods: As a major method for to determine tunnel bottomhole zone geospatial position it is proposed to consider ground-based laser scanning technology. Scanning result processing was implemented in specialized software package Leica Cyclone 3DR. Results: Existing experience of geodetic check of deformations in tunneling by New Austrian method is considered. Processing results for data on ground laser scanning of a tunnel separate fragment are presented, a tunnel mathematical three-dimensional model is obtained and assessment of deviations of tunnel actual surface from obtained theoretical one is fulfilled. Practical significance: The obtained threedimensional model can be further used for geodetic monitoring of deformations. Theoretical bases for estimation required accuracy for deformation characteristics definition are substantiated which are based on the transition from construction tolerances to average quadratic errors of deformation characteristics definition and then to average quadratic errors of coordinates for laser scanning points. The enlarged stages of scanning are defined with view of tunneling technology of New Austrian method.

Published: January 2023

Purpose: Definition of the most effective methods and components for strengthening weak Yoldian clays used in the creation of transport routes in the North regions. Methods: The definition of the main physical-mechanical characteristics of clay soil was carried out in accordance with the requirements: of GOST (Russia State Standard) 12536—2014 “Soils. Methods for laboratory determination of granulometric (grain) and microaggregate composition”; GOST 25584—2016 “Methods for laboratory determination of the filtration coefficient”; GOST 22733—2016 “Soils. Method for laboratory determination of maximum density”; GOST 5180—2015 “Soils. Methods of laboratory determination of physical characteristics”; GOST 25100—2020 “Soils. Classification”. It is shown that the effective strengthening of weak clay soil is achieved as a result of its preliminary stabilization with the help of granulated blast-furnace slag or natural limestone of ≈2.5 mm fraction. The rational amount of granulated blast-furnace slag or limestone is 15 wt.% of the soil mass and at the same time, clay soil has the highest strength value — (2.25–2.45) MPa. The difference in strength indicators in favor of limestone constitutes 9.0%. It has been experimentally established that in order to increase reinforced clay soil strength it is effective to use granulated blast-furnace slag in combination with finely ground blast-furnace slag which rational amount of is 10 wt.% of soil mass which achieved strength of corresponds to M20–M25 grade. It has been defined that for comprehensive improvement of the indicators as strength, density, and frost resistance it is necessary to introduce additionally to clay soil, reinforced with blast-furnace metallurgical slag as reactive components which it’s effective to use Portland cement in amount of not more than 5 wt.% of soil mass in combination with dry complex chemical additive “PRA” which rational amount of constitutes 2.0 wt.% by weight of (Portland cement + finely ground blast-furnace slag). Practical significance: Stabilized and comprehensively strengthened weak clayey soil is characterized by the following actual indicators: M50 F35 K10 — 0.026 m/day which can be used as a base at construction of transport routes of local importance in the regions of the North.
