Authors: Dornyak Olga , Markova Ludmila , Popikov Sergei , Tanchuk Pavel
Published: September 2023

The safe and effective modes of operation of handling equipment of the manipulator type for the forest complex assume a mandatory horizontal position of the frame of the mobile technological machine. In unfavorable production conditions, a forest transport machine may find itself in a critical situation associated with the rotation of the manipulator's support frame relative to the horizon. Correction of this situation can be provided through the use of outriggers. This paper presents the results of a theoretical study of static loads that are characteristic of hydraulic cylinders of outriggers and other elements of the hydraulic manipulator of a forest transport machine with its various configurations. Technologies for loading, moving and unloading forest cargoes can be carried out using special equipment, subject to certain rules. The safe and effective operation modes of manipulator handling equipment assume a mandatory horizontal position of the support-turntable. In unfavorable production conditions, the wood transport machine may find itself in a critical situation related to the rotation of the support and turning frame of the manipulator relative to the horizon. Correction of such position can be insured by use of outriggers. This paper presents the theoretical study results of the static loads, which are characteristic for the hydraulic cylinder of outrigger and other elements of the hydraulic manipulator of a timber transport machine in its various configurations. Balance equations in generalized coordinates are used to describe the equilibrium conditions of the mechanical system under study, which includes a basic vehicle, outriggers, a boom, a handle with a telescopic extension, a grip device and hydraulic drives that ensure their functioning. The rotation angle of support-turning frame in vertical plane, the boom rotation angle, the handle rotation angle and extension of the telescopic part are selected as generalized coordinates. Analytical expressions are obtained for forces on rods of hydraulic cylinders and the working fluid pressure values in piston cavities of hydraulic cylinders in equilibrium state at different position of manipulator links. Calculations based on the obtained formulas can be used in designing technological modes of operation of timber transport machines for carrying out loading and unloading operations of cargoes with the possibility of bringing the support-turntable into a horizontal position.

Authors:   Department of Physics, Tri-Chandra Multiple Campus, Tribhuvan University, Kathmandu, Nepal., Khadka Chandra Bahadur
Published: September 2023

Partial differential equations such as those involving Bessel differential function, Hermite’s polynomial, and Legendre polynomial are widely used during the separation of the wave equation in cylindrical and spherical coordinates. Such functions are quite applicable to solve the wide variety of physical problems in mathematical physics and quantum mechanics, but until now, there has been no differential equation capable for handling the problems involved in the realm of special relativity. In order to avert such trouble in physics, this article presents a new kind of differential equation of the form: , where c is the speed of light in a vacuum. In this work, the solution of this equation has been developed via the power series method, which generates a formula that is completely compatible with relativistic phenomena happening in nature. In this highly exciting topic, the particular purpose of this paper is to define entirely a new differential equation to handle physical problems happening in the realm of special relativity.

the styloid process lengthening or the stylohyoid
ligament being calcified. Eagle syndrome
patients frequently experience dysphagia,
dysphonia, cough, voice changes, otalgia, sore
throat, face pain, a feeling of a foreign body,
headache, vertigo, and neck pain. When a patient
experiences unilateral idiopathic pain, especially
in adult women, and the pain is not relieved by
analgesics, Eagle's syndrome should always be
taken into account. For symptoms that are not
identifiable, patients see multiple doctors with
varied outcomes.
MATERIAL & METHOD
This study was performed as a retrospective
study in Asian institute of medical sciences on 68
patients with elongated styloid process between
January 2022 to October 2022 with symptoms of
throat pain, otalgia, foreign body sensation in
throat and neck pain.In these situations, a
multidisciplinary approach and early radiological
evaluation, particularly an x-ray of the styloid
process, are necessary.
CONCLUSION
This study was conducted to establish a correct
diagnosis, determine the underlying reason of the
patient's ambiguous symptoms, and evaluate the
effectiveness of gabapentin and carbamezapine.

EFFICACY OF CO-TEACHING ON LEARNERS’ PERFORMANCE IN ENGLISH LANGUAGE IN INCLUSIVE EDUCATION IN KADUNA STATE OF NIGERIA
Authors: Dr. Bila G. Jamila  , Prof. Sa’ad M. Tajuddeen  , Tauna Juliet
Published: September 2023

This study is premised on investigating the efficacy of co-teaching on learners performance in English language in inclusive education in Kaduna state of Nigeria. Co-teaching is a delivery instruction method where two or more professionals blend group of students in a single physical space. Co-teaching appeared in the literature in the early 1990s as a way to better address the needs of special education students. There are several different models of co-teaching which include one teaches, one observes, one teaches, one assist, station teaching, parallel teaching, supplementary teaching, alternative or differentiated teaching, and team teaching. Co-teaching also has a lot of benefits for the students or learners as well as the teachers. Inclusive education is a philosophy that advocates equal opportunities for all children regardless of whether they have a disability or not. It is primarily about restructuring school culture, policy and practice so that it responds to the diversity of students in the locality. It has its advantages and disadvantages. This study focused on the efficacy of co-teaching on learners performance in English language in inclusive education at Nabeela Academy in Kaduna, Nigeria. Experimental design was used to generate data for analysis. The study constituted of two groups, an experimental group (x) and a control group (-x) of JSS III students. They were exposed to a pretest and a posttest in English which was the instrument used for data collection. Simple percentage, mean and standard deviation was used to analyze the research questions and independent sample test was used to test the hypothesis. From the analysis of data, the findings revealed that, there was no significant difference in the pretest scores of learners and the posttest scores after being exposed to co-teaching. The findings also showed that the correlation and t cannot be computed because the sum of case weights is less than or equal to 1. This imply that because there was only student in the control group, a male, the statistical tool used in analysis could not analyze the data because the value was just 1. However, the result showed a mean difference of 7.500. This means that the female learners who constituted the experimental group (x) performed far better than the male in the control group both in the pretest and posttest. There was no statistical data to measure the collaborative performance of teachers through co-teaching on English language. However, the difference in the mean score of the student in control and that of the experimental groups reveals that interaction of teachers’ collaboration in the experimental group affected the students positively.

Published: September 2023

At present, increasing the energy efficiency of radio electronic equipment is one of the most important tasks in the development and modernization of equipment for all radio services, and in some areas of application of radio electronic equipment, energy efficiency is critical. The main problems that occur in the development and operation of radio transmitting equipment are considered, and solutions are listed that can increase the efficiency of transmitters. Since the increase in energy efficiency is especially important for high-power power amplifiers of the final stages of transmitters, in this paper we analyze the radio transmitters switching operating modes, suitable for building modulators of the final stages of radio transmitters of digital broadcasting systems. The operating modes of switching power amplifiers and methods for achieving high energy efficiency of power amplifiers are discussed, their advantages and disadvantages are shown. The comparative analysis of circuits and classes of various types switching power amplifiers showed that each of them has a number of disadvantages that do not allow choosing the universal optimal version of such amplifier, so that the use of specific power amplifiers depends of the transmitter required characteristics. Another way is to use synthetic and combined methods for constructing high-performance power amplifiers to increase of the transmitters final stages resulting efficiency.

Accurate construction of time series forecasts is a key element in the system of support and management decision-making. This article presents a method of multi-stage system forecasting of time series. The effectiveness of the proposed method is experimentally justified by the example of the arrival of car traffic at the junction points of railways. The most important contribution is the introduction of a system forecast, in which the methods of forecasting traffic flows will be mutually consistent and complementary, since the use of statistical methods alone will not fully reflect all the changes that occur in the transport complex of the Russian Federation. This hybrid combination provides more competitive forecasts compared to other methods. Moreover, such a hybrid model is easier to interpret by decision makers when modeling trend series.
FINDING INFORMATION SETS WHEN CORRECTING ERROR BURSTS WITH QUASI-CYCLIC CODES
Authors:   Saint-Petersburg State University of Aerospace Instrumentation, ISAEVA M.N.
Published: September 2023

This article discusses the question of assessing the probability of finding information sets in block-permutation and block-circulant matrices. Traditionally, interference-resistant coding is considered independent errors, however, in real systems they can be grouped and generate a so-called error burst. Known estimates of the probability of finding information sets are conducted for random matrices, and for correcting error bursts widespread block-permutation low density parity check codes (LDPC-codes) or block-circulant quasi cyclic codes (QC-codes) can be used. To estimate the probability of finding information sets mathematical modeling was used. Experiments have been carried out to identify parameters for specific structures that give the greatest probability of finding information sets. The article presents the results reflecting certain features in the values of the probability of finding information sets for matrices of different types, given assumptions and hypotheses about the features. Dependence of the presence of an information set from the size and location of its search interval inside the block permutation matrix was identified. The results of this research may be used to reduce the complexity of decoding by information sets, which, when considering random matrices, is exponential.

Eye-tracking technology has been extensively used in web development, marketing, and gaming mechanics because of the ability to obtain data regarding the trajectory and gaze fixation points. Eye movement information may be effectively used to study complex cognitive processes and human visual perception. However, a significant issue of leaking user privacy has arisen with the expansion of eye-tracking technology. Since the technology can obtain highly sensitive information regarding user behavior and preferences, measures for protecting personal data are required. At the current stage of the development of technology, research on threats and means to ensure the security of personal data has become a high priority in this field. Proper diligence in the development and use of eye-tracking devices is becoming an integral part of the process. Potential threats associated with collecting, storing, and trans mitting information about users' gaze should be considered. Various methods have been proposed to ensure the security of personal data through the use of eye-tracking devices. The anonymization of data, which is the removal or replacement of personal identifying elements, appears to be among these. Transparency and user agreement to the collection and use of gaze data has also been an important aspect. This can be accomplished by explicitly providing information about the purpose of the data collection and the ability to control privacy. Threats related to the use of eye-tracking technology were considered, providing methods of ensuring the security of personal data. These are important steps in the development of the field to protect user privacy while improving the safety and ethics of using eye-tracking devices.

Published: September 2023

The microparticles interaction with potential barriers of various nature and form is the quantum physics and nanoelectronics basis. The nature of this interaction largely determines modern radio engineering devices and complexes operation, information transmission and processing systems. At present, semiconductor quantum-well structures, in particular heterostructures with quantum wells (QWs) and barriers (QWs), occupy leading positions as materials for opto- and nanoelectronics. It has been found that chain consisting of a sequence formation of potential wells and barriers gives rise to resonant levels for which the structure transparency is equal to unity. With an increase in the number of chain links, these levels split into close sublevels, the energy and half-width of which depend on the barriers parameters and the number of chain cells. A technique is proposed to determine the characteristics of these levels, in particular, the half-width of sublevels. The wave function dependence on chain parameters is studied. Problems related to the propagation of waves in layered media also arise in many other branches of science and technology. In particular, such media as plasma, ionosphere, atmosphere, ocean contain layered structures. Solving the problems of wave propagation in these media, calculating the reflection and transmission coefficients during the propagation of electromagnetic waves are of great importance both for calculating radio paths with reflection from the ionosphere and for many problems of remote diagnostics of ionospheric plasma. The issues discussed in this paper may be of interest to specialists in these areas.

The use of modern methods of synthesis of electrical circuits makes it possible to create circuits with frequency characteristics of any complexity that do not require restructuring. However, when solving the problem of creating tunable filters, additional requirements arise for the filter and tuning technologies, especially if we are talking about creating systems in the frequency region bordering between frequencies, where implementation in the form of systems with lumped and distributed parameters is inconvenient in both cases. This article is devoted to the synthesis of a stop filter under such conditions. The goal of synthesizing tunable filters is to obtain either a constant absolute or constant relative bandwidth. The first requirement is typical for radio receiving devices, where it is necessary to ensure the minimum permissible bandwidth during tuning, the second – for radio transmitting devices, where minimum losses in the passband and a constant harmonic filtering coefficient are required. A modified method for the synthesis of rejection filters according to operating parameters is described, the synthesis of a specific filter and technological solutions for its implementation, the choice of a method for its electronic restructuring is described.

Today, it is not possible to abandon modern sources of information; with such rapid development of technology, we need to analyze large amounts of data. To a greater extent, applications that require speed and volume of transported information are responsible for the increase in transmitted data, such as streaming and cloud data processing services, as well as traffic transfer between data centers. The experimental part of the research involves several schemes for distributing a quantum channel inside a multi-core fiber, as well as different models for placing classical channels. To transmit the quantum channel, scientific and educational complexes developed by the Qrate company were used; the transmission of the quantum channel was implemented based on the BB84 protocol. The article analyzes experimental studies on the parallel transmission of three quantum channels in a multi-core optical fiber with satisfaction of the quantum bit error rate and key length, as well as a study of the influence of classical power on the transmission of a quantum channel along the adjacent core of the fiber under study. Such research provides a new direction for the development of microstructured fibers specifically for the needs of quantum communications.

Published: September 2023

Currently, there is an active development of wireless data transmission systems. A solution widely used in improving existing and creating new wireless communication technologies, which allows increasing spectral efficiency and transmission speed, is the use of systems with Multiple-Input-Multiple-Output, MIMO. In this regard, research into the potential capabilities of MIMO systems under various operating conditions is an urgent task. In particular, the issue of the influence of the correlation of transmission matrix elements on the efficiency of the communication system is important. We will further consider cases of multipath propagation typical for urban conditions. We will also consider the signals transmitted by different antennas to be narrowband and independent of each other. For the two currently most commonly used MIMO radio channel models, the influence of the correlation between the elements of the transmission channel matrix on the efficiency of the MIMO system was studied using statistical tests. Dependences of the error probability per bit of transmitted information on the signal-to-noise ratio were obtained for channels with transmission matrices whose covariance matrices have varying degrees of difference from the diagonal (unit) matrix. When generating channel matrices with correlated elements, the unstructured (general correlation) model and the Kronecker model are used.
DETECTION OF OBJECTS ON THE IMAGES OBTAINED FROM THE SPATIAL RANGEFINDER
Authors:   University of Diyala – College of Engineering, Abdulameer Abdulkadhim Hussein
Published: September 2023

Over the past few years, entire families of new recording devices have emerged that allow three-dimensional object tracking, localization, and surface reconstruction. This has led to an increase in a variety of practical applications. The most typical such application to date is digital three-dimensional models of the environment obtained using a variety of sensor devices such as ultrasonic, laser and infrared rangefinders. The analysis performed showed that the most effective procedure for identifying objects in spatial rangefinder images is the procedure based on the analysis of partial line-by-line histograms of the image. The essence of this method is to calculate the brightness values in each line of the image and count the number of these values in the entire line. This procedure is based, among other things, on the results of visual analysis of images obtained from a spatial rangefinder. This analysis shows that the boundary of an object is usually quite clearly distinguished in the upper part of the object, conventionally “rising” above the horizon. Detecting objects in an image is a difficult task because of the proximity of the color values of the pixels, and there is no specific method that allows to provide an absolute precision in the results of processing of the image sequence. In this paper, proposed to use the method of histogram analysis to detect objects on a sequence of images obtained with the help of spatial rangefinders.

Published: September 2023

Aim: To identify the necessary competencies that future professionals must obtain in order to effectively manage patients with chronic conditions. We employed a multilayer review in PubMed, Scopus and Cochrane.
Materials and Methods: We applied three searches in PubMed, Scopus, and Cochrane using various terms in order to identify the necessary skills and competences needed for healthcare professionals to provide distance care in patients with chronic conditions. From the initial search, a total of 1008 studies were identified while 54 met the inclusion criteria and were retained for data extraction. After the review of the 54 studies, we grouped the proposed skills and competencies in eight major categories. Those groups were Clinical Knowledge, Critical Thinking Skills, Technological Skills, Clinical skills, Communication skills, Implementation skills, Professionalism and professional ethics, Evidence based Practice.
Conclusions: Although telehealth is gaining ground in healthcare practice and healthcare professionals possess the necessary knowledge and skills to provide safe, effective, and personalized care, additional specialized training is nevertheless required to provide telecare. Therefore, the integration of telehealth into various healthcare professions curricula - both at undergraduate and postgraduate levels – is required for the development of education and the dynamic development of healthcare.
Affective Rhythms: Experience of Trauma in Alan Clarke’s Films from the 1980s
Authors: Kosińska Karolina
Published: September 2023

Alan Clarke’s films from the 1980s are usually characterized as radical tests of the boundaries of social realism and narrative minimalism. As such, they have been described as highly political, although their political potential relates primarily to form rather than content (plot or story). Clarke’s critical approach to current affairs in Britain leads not only to a stark and pessimistic diagnosis of the state of the nation and the country but also to an analysis of the national and social traumas of the 1980s. Specific formal and narrative strategies employed by the director are highly affective – he uses intersecting patterns of different, persistent, and repetitive rhythms, visual, aural, and temporal, not to convey an intellectual meaning but rather to affect the viewer, to immerse them in a kind of trance-like experience. The author uses Jill Bennett’s reflections on trauma and affect in art to analyse the rhythmic designs of two of Clarke’s films: Road (1987) and Contact (1985).

ABSTRAK

Kerjasama (coorperation), yaitu sikap mau bekerjasama dengan kelompok. Anak yang berusia dua atau tiga tahun belum berkembang sikap kerja samanya. Mulai usia tiga tahun akhir atau empat tahun, anak sudah mulai menampakkan sikap kerja samanya dengan anak lain. Pada usia enam atau tujuh tahun, sikap kerja sama ini sudah berkembang dengan lebih baik lagi. Namun, sebagian anak masih belum dapat bekerjasama dengan temannya dan juga tidak bisa berbagi dalam kelompok terlihat dalam hal mengerjakan tugas kelompok anak masih berebutan potongan kertas, lem, gambar dalam kegiatan kolase dan saling berebut bermain balok. Anak tidak terlihat aktif, terlihat dari kurangnya interaksi anak ketika menyelesaikan tugas kelompok, anak tidak mau membantu mengerjakan tugas kelompok bahkan hanya melihat temannya bekerja. Penelitian ini dilakukan untuk mengetahui pengaruh permainan gobak sodor terhadap kemampuan kerjasama anak. Penelitian ini merupakan penelitian kuantitatif metode eksperimen. Sampel adalah anak kelompok B TK Intan Sari Palangka Raya yang berjumlah 17 orang. Data dikumpulan dengan lembar observasi yang berisi 3 aspek. Hasil penelitian menunjukkan bahwa nilai thitung adalah 5,85, ttabel dengan taraf signifikan yaitu 5% (2,120). thitung 5,85 > ttabel 2,120. Berdasarkan hasil tersebut maka Ho ditolak dan Ha diterima. Sehingga dapat disimpulkan bahwa hasil penelitian Permainan Gobak Sodor Berpengaruh Terhadap Kemampuan Kerjasama pada Anak Kelompok B TK Intan Sari Palangka Raya tahun Ajaran 2019/2020.

Lacosamide is a third-generation anticonvulsant used in the treatment of epilepsy. While therapeutic levels for various patient subpopulations are still under investigation to achieve optimal responses, therapeutic drug monitoring has been proven to be useful in improving patient management. To ensure the reliability of results, it is essential to establish a reliable quantitative method. Thus, the aim of this study was to develop and validate a simple and feasible method for quantifying lacosamide in human plasma, with the specific aim of facilitating drug monitoring purposes. A high-performance liquid chromatography method with ultraviolet detection was developed for the quantification of lacosamide in human plasma. Analyte recovery was achieved through ethyl acetate extraction, with propranolol serving as the internal standard. A C18 column and a mobile phase consisting of 10 mM phosphate buffer and acetonitrile (70:30 v/v, pH = 3.5) were employed. Validation parameters included specificity, linearity, repeatability, precision, accuracy, sensitivity, and stability. The method exhibited linearity within the range of 2.5 – 30 μg/ml (R2 = 0.997), with a limit of quantitation of 2.29 μg/ml. The average recovery percentage was 100.2%, and it proved to be accurate, precise, and specific. In plasma samples, the drug content remained stable for 72 h at 4°C, 1 month at −20°C, and 2 years at −80°C. The post-processed sample remained stable for 1 week under all tested conditions. Due to its simplicity, short analysis time, sensitivity, and cost-effectiveness, the proposed analytical method proves to be useful for therapeutic monitoring and pharmacokinetic studies of lacosamide.
