An Algorithm for Estimating the Velocity of a Moving Target Based on Mellin Matched Filter
Authors: Monakov A. A. 
Published: June 2022

Introduction. Construction of the radar image of a moving target and estimation of its velocity in synthetic aperture radars (SAR) presents a relevant research problem. The low quality of radar imaging is frequently related to the phenomenon of range cell migration (RCM). Conventional methods for RCM compensation, which are successfully used to obtain radar images of stationary targets, fail to provide the required quality when applied to moving targets. At present, a number of algorithms are used to solve this problem. However, the majority of them employ optimization procedures when searching for estimates of unknown parameters, which fact greatly complicates their implementation. An exception is the LvD algorithm, which implements double keystone transform to construct a radar image without using complex estimate search procedures. Radar images are constructed in the coordinates "longitudinal velocity - lateral velocity", which facilitates estimation of the target velocity components.Aim. Development of an alternative algorithm based on the Mellin matched filter (MMF) for estimating the velocity and constructing the radar image of a moving target in a side-looking SAR.Materials and methods. The derived algorithm is based on the invariance of the integral Mellin transform to the signal scale and uses the MMF to estimate the target velocity components.Results. An algorithm for constructing the radar image of a moving target based on the MMF was synthesized. An analysis of the LvD algorithm showed its capacity for selecting the optimum scale factor when implementing a second KT. The conducted computer simulation of the MMF and LvD algorithms showed their equal accuracy. Under the same simulation scenarios, both algorithms yield effective estimates of the velocity components of a moving target when the signal-to-noise ratio is greater than -10 dB.Conclusion. The proposed algorithm for constructing a radar image can be used in SAR systems designed for detection and velocity estimation of a moving target.

Published: June 2022

Introduction. Small unmanned aerial vehicles (UAVs) are a growing threat due to their possible use for illegal activities. Currently, passive coherent radar systems are widely used to detect, track and recognize moving targets, including small UAVs, which makes them a promising tool for use in modern airspace radar monitoring systems. At the same time, recognition of small UAVs becomes a challenging task due the possibility of confusing them with birds, particularly in maritime areas with large bird populations. In a search for new solutions to the problem of recognizing small UAVs, trajectory features can be used.Aim. To analyze differences between the trajectory features of low-flying low-speed targets in order to verify the possibility of their use for recognition purposes.Materials and methods. Real radar measurements of UAVs and birds obtained by a passive coherent radar system were used. Specific characteristics of the trajectory parameters of target classes were built using computer statistical modeling in the MatLab environment. Differences in the movement trajectory of targets were established by comparative analysis.Results. Significant differences between the flight path of UAVs and birds were found. Specific features of the trajectory of small aerial targets of each type were investigated. On the basis of radar measurement, graphs of the characteristic trajectory parameters of UAVs and birds were plotted. The conducted comparative analysis allowed identification of the characteristics of the flight path of each target type in each movement segment. Trajectory features that can be used for recognition purposes were identified.Conclusion. The practical significance of the proposed trajectory features and the possibility of their implementation in the development of an algorithm for recognizing low-flying low-speed radar targets using passive coherent radar systems was established. The knowledge of differences between the flight path of UAVs and birds can improve the quality of the UAV recognition problem.

Published: June 2022

Introduction. Modern precision radio systems impose stringent requirements on the quality of the reference signal sources used. Various approaches are used to create sources of reference signals in the microwave range – micro-wave self-oscillators (SO). A promising direction in the development of such SO is SO with frequency-setting elements based on surface acoustic waves (SAW).Aim. A review of international achievements in the development of frequency-setting elements based on SAW and respective SO.Materials and methods. The selection of materials for a comparative analysis and generalization was carried out using available sources published over the past 30 years in well-known engineering journals, advertising brochures and websites of the manufacturers of devices based on SAW. The selection criteria included low values of the power spectral density of the frequency fluctuations of the generated signal, the presence of vibration protection, the presence of a thermostat, as well as the miniaturization and originality of the design.Results. Specific features of various methods used for constructing microwave oscillators were analyzed. It is shown that the achievement of the best values of the power spectral density of frequency fluctuations in SO with frequency-setting elements on SAW is possible only with the use of two-port resonators. An analysis of the main technical characteristics of temperature-controlled vibration-resistant SO was carried out.Conclusion. Despite the large number of different manufacturers on the world market (more than 20 companies) and the variety of different models of oscillators with frequency-setting elements on SAW (more than a 100 different models), only two companies produce oscillators resistant to external vibrations and acoustic noise.
Comparative analysis of osteopathic correction and standard comprehensive rehabilitation of patients with posttraumatic contractures of the upper limb joints
Authors: Zamanov A. R. , Miroshnichenko D. B. 
Published: June 2022

Introduction. Prolonged immobilization of the upper limb after various injuries leads to persistent contracture. Contractures of the upper limb joints are a severe orthopedic pathology that leads to a long-term decrease in working capacity and permanent disability. In the absence of treatment, the persistent changes in the articular elements can develop. Patients with contractures of the upper limb joints get treatment for a long time in polyclinics and hospitals, but the treatment does not always lead to the desired results. At the same time, an essential condition for treatment in outpatient medical institutions is the possibility of daily self-care and independent movement of the patient, as well as daily visits to a medical institution, but it is not always possible. In this regard, the search for treatment methods with comparable effectiveness, but requiring a signiﬁ cantly smaller number of medical procedures and, accordingly, visits to specialized institutions, is relevant. Osteopathic correction could potentially be among these methods.The aim of the study is to compare the effectiveness of osteopathic correction and standard complex rehabilitation of patients with post-traumatic contractures of the upper limb joints.Materials and methods. The study involved 40 patients suffering from post-traumatic contractures of the upper extremities. Two groups were formed by the method of simple randomization: the main group (20 people who received osteopathic correction — 3 sessions with a frequency of 1 time in 7 days), and the control group (20 people who received standard complex rehabilitation, which included physiotherapy, physiotherapy exercises and mechanotherapy, daily for 10 days). The osteopathic status, the motion range of the upper limbs joints, and the hand muscles strength were assessed in all patients at the beginning and at the end of the study.Results. A statistically signiﬁ cant (p<0,05) increase in the motion range and the hand muscles strength was found in both groups at the end of the study. In patients of the main group, receiving osteopathic correction, a statistically signiﬁ cant decrease (p<0,05) in the detection frequency of some regional and local somatic dysfunctions was observed.Conclusion. The obtained results indicate the comparable results of the osteopathic correction of the upper limb joints post-traumatic contractures, and of the standard complex rehabilitation. Since osteopathic correction of post-traumatic contractures is carried out once every 7–10 days, it can be recommended for patients who, for various reasons, cannot regularly visit outpatient rehabilitation departments for a long time.

Published: June 2022

The purpose of this scientific article is concentrated by author in revealing the most characteristic style traits concerning neo-romanticism handwriting of composer Alexander Nezhigay, which are represented in compositions by master for wind academic instruments. The row of methods for this scientific process is based on operating by series of theoretic and empirical ways of the investigation, a namely analysis and synthesis, induction and deduction, interviewing as well as a method observation of scientific object, which is used by author into process for studying and generalization of experience concerning introduction of wind compositions by A. Nezhigay into different sphere of wind academic musically performing art (pedagogy, competion, concert, culturally education). Scientific newness of the article is conditioned by absent appealing of researchers to studying of A. Nezhigay’s creative heritage for wind instruments in the light of style peculiarity of composer’s handwriting. The novelty of article is also revealed by affirmation as research material the series composition by A. Nezhigay for wind instruments, a namely „Inspiration” for clarinet solo, „Scherzo” for oboe and piano, „Lullaby” for clarinet and piano, cycle „Introduction and toccata” for clarinet and piano, which were not in the center of problematically style scientifically investigative attention of scholars. Conclusions. The neo-romanticism traits of A. Nezhigay’s creativeness is discovered on the example of compositions by master for wind academic instruments. Among them, we accent romantic imagery, which is dominant for idea-artistic content of composition; melodic variation type of representation themes, what finds the manifestation into technique of variation repetition; using traditional artistically expressive opportunities of wind academic instrumentation (timbre and dynamic pallets, articulatory performing arsenal); accentuation of deeply individual, intimal condition of person – romantic individual-lyric.
Minimalism and monotimbre flute ensemble in the creativeness of G. Beeftink (on the example of the composition „Birds”)
Authors: Gontovaya Larisa , Kolimbet Svetlana 
Published: June 2022

The purpose of the study includes coverage of the interdependence of the technique of minimalism and the timbre of the ensemble on the example of the work of Herman Beftink, a namely the composition „Birds” for flute, flute-piccolo and alto-flute. In accordance with the purpose, the task of the study is to consider the formation of minimalism in music and its features of development, the role of software and the function of timbres in relation to the tasks in minimalism. A study of the work of modern American composer G. Beftink and the role of the flute and flute ensembles in his art. Research methods used in the writing of the article: empirical methods (description, comparison, generalization), theoretical knowledge (from abstract to concrete), analysis of musical work, observation, analogy, systematic approach. Scientific novelty. For the first time in Ukrainian musicology the composer Herman Beеftinkʼs work and his flute music were explored. Consideration of the interaction of timbres, namely the flute and its varieties, with the tasks of minimalism. Conclusions. The minimum semantic volume, the absence of any claims to its versatility in minimalism is paradoxical: the listener is immersed in the contemplation of sound ornaments and discovers their infinity and symbolism. Sound patterns can be compared with well-known in musical history sound formulas, which were associated with other styles and tasks. In this case, it’s a kind of natural symbols, referring to the endless stay in nature. The interconnection of compositional technique and monotimbre composition is a consequence of influence of the aesthetics of the soundtrack in Beeftinkʼs works and the association with the eastern identity of music and treatment of which are relieving person from fear of everything material.
Genotype x Environment x Management (GEM) Reciprocity and Crop Productivity
Authors: Mahmood Tariq , Ahmed Talaat , Trethowan Richard 
Published: June 2022

Human population growth requires food production to increase at a matching pace. Crop productivity largely depends on GEM reciprocity and variation in any factor may potentially alter the overall response. Introduction of improved cultivars causes interactive responses within the farming system which may produce tangible benefits only in the presence of suitable environments and management practices. The yield gap which is defined as the difference between yield potential and average farm yield varies in extent among regions ranging from moderately high to alarmingly high. Variation in environments and management practices impacts both the quantity and quality of produce. The highest gains can be achieved if factors in the interaction model work complementarily. System efficiency indicators are useful for assessing the overall system performance. In the face of new challenges plant breeding is receptive to shifts in objectives and strategy. Extension experts are trained to transfer technology and help farmers optimise for better gains. The extension service is also crucial for feedback to researchers. Better crop management has helped realize the genetic potential of crop cultivars in specific settings. Once a productivity plateau has been reached following optimization of management practices for specified environments, then further improvement of the system can be attained through new genetic interventions. For higher productivity a stronger linkage among researchers, extension experts, and farmers is vital. To help the decision support systems GEM interactions need precise scientific analysis and interpretation. A general account rather than a specific view on GEM reciprocity is presented.

Background: The diagnosis of osteoporosis is still one of the most critical topics for orthopedic surgeons worldwide. One research direction is to use existing clinical imaging data for accurate measurements of bone mineral density (BMD) without additional radiation.Methods: A novel phantom-less quantitative computed tomography (PL-QCT) system was developed to measure BMD and diagnose osteoporosis, as our previous study reported. Compared with traditional phantom-less QCT, this tool can conduct an automatic selection of body tissues and complete the BMD calibration with high efficacy and precision. The function has great advantages in big data screening and thus expands the scope of use of this novel PL-QCT. In this study, we utilized lung cancer or COVID-19 screening low-dose computed tomography (LDCT) of 649 patients for BMD calibration by the novel PL-QCT, and we made the BMD changes with age based on this PL-QCT.Results: The results show that the novel PL-QCT can predict osteoporosis with relatively high accuracy and precision using LDCT, and the AUC values range from 0.68 to 0.88 with DXA results as diagnosis reference. The relationship between PL-QCT BMD with age is close to the real trend population (from ∼160 mg/cc in less than 30 years old to ∼70 mg/cc in greater than 80 years old for both female and male groups). Additionally, the calculation results of Pearson’s r-values for correlation between CT values with BMD in different CT devices were 0.85–0.99.Conclusion: To our knowledge, it is the first time for automatic PL-QCT to evaluate the performance against dual-energy X-ray absorptiometry (DXA) in LDCT images. The results indicate that it may be a promising tool for individuals screened for low-dose chest computed tomography.

Published: June 2022

This study presents the design and characterization of new monochromatic light-harvesting systems based on inorganic porous materials hybridized with organic dye molecules within their structure. A new fluorescent BOPHY dye was prepared, characterized optically and used as both reference and synthetic precursor for two alkoxysilane derivatives that were incorporated separately within a silica structure. The dyes, one bearing one alkoxysilane group and the other one two, were co-condensed with tetraethyl orthosilicate to form a hybrid organo-silica framework, where they are found at specific locations. The structure of the new materials was analysed by powder XRD and TEM, which confirmed the presence of the hexagonal pore arrangement typical of mesoporous MCM-41 silica particles. The steady-state and time-resolved analysis showed that the particles where the dyes are most dispersed within the framework retain the highest fluorescence quantum yield, up to 0.63, in the green-yellow region of the visible spectrum. On the other hand, increasing the content of BOPHY units in the solid matrix seem to favour non-radiative deactivation pathways and aggregation phenomena, which lower the efficiency of light emission. The materials also exhibit interesting properties, such as a dual excited-state decay and fluorescence anisotropy. The short fluorescence lifetime, about 2 ns, matches the typical singlet lifetime of BOPHY dyes, whereas the long component, up to 20 ns, is attributed to delayed fluorescence, which could take place via charge recombination. Optical anisotropy experiments revealed that all materials show polarised light emission to a significant extent and, for most samples, it was also possible to determine a polarisation transfer decay trace, from 400 to 800 ps This is ascribed to the occurrence of energy migration between neighbouring dye units within the silica structure.
