Low Temperature Powder Bed Fusion of Polymers by Means of Fractal Quasi-Simultaneous Exposure Strategies
Authors: Schlicht Samuel , Greiner Sandra , Drummer Dietmar
Published: April 2022

Powder Bed Fusion of Polymers (PBF-LB/P) is a layer-wise additive manufacturing process that predominantly relies on the quasi-isothermal processing of semi-crystalline polymers, inherently limiting the spectrum of polymers suitable for quasi-isothermal PBF. Within the present paper, a novel approach for extending the isothermal processing window towards significantly lower temperatures by applying the quasi-simultaneous laser-based exposure of fractal scan paths is proposed. The proposed approach is based on the temporal and spatial discretization of the melting and subsequent crystallization of semi-crystalline thermoplastics, hence allowing for the mesoscale compensation of crystallization shrinkage of distinct segments. Using thermographic monitoring, a homogenous temperature increase of discrete exposed sub-segments, limited thermal interference of distinct segments, and the resulting avoidance of curling and warping can be observed. Manufactured parts exhibit a dense and lamellar part morphology with a nano-scale semi-crystalline structure. The presented approach represents a novel methodology that allows for significantly reducing energy consumption, process preparation times and temperature-induced material aging in PBF-LB/P while representing the foundation for the processing of novel, thermo-sensitive material systems in PBF-LB/P.
A Random Subcarrier-Selection Method Based on Index Modulation for Secure Transmission
Authors: Zhan Tao , Chen Jiangong , Luan Shan , Lei Xia
Published: April 2022

Recently, a frequency diverse array (FDA) has been employed in an orthogonal frequency division multiplexing (OFDM) transmitter to achieve secure wireless communication without mathematical encryption. However, an insecure coupling effect arises if the frequency increments are linearly assigned to all antenna elements. To solve this problem, random subcarrier-selection methods are proposed; however, the challenge lies in the random selection of subcarriers. Inspired by the randomness of index modulation (IM), this paper proposes a low complexity random subcarrier-selection method based on index modulation (RSCS-IM). Specifically, this work conducted analysis on the spectral efficiency (SE) of our system and the computational complexity of RSCS-IM, which works out a closed-form expression of the BER performance of a desired position and validates the theoretical outcomes through simulation.

In this paper, we studied the possibility of increasing the Brillouin frequency shift (BFS) detection accuracy in distributed fibre-optic sensors by the separate and joint use of different algorithms for finding the spectral maximum: Lorentzian curve fitting (LCF, including the Levenberg–Marquardt (LM) method), the backward correlation technique (BWC) and a machine learning algorithm, the generalized linear model (GLM). The study was carried out on real spectra subjected to the subsequent addition of extreme digital noise. The precision and accuracy of the LM and BWC methods were studied by varying the signal-to-noise ratios (SNRs) and by incorporating the GLM method into the processing steps. It was found that the use of methods in sequence gives a gain in the accuracy of determining the sensor temperature from tenths to several degrees Celsius (or MHz in BFS scale), which is manifested for signal-to-noise ratios within 0 to 20 dB. We have found out that the double processing (BWC + GLM) is more effective for positive SNR values (in dB): it gives a gain in BFS measurement precision near 0.4 °C (428 kHz or 9.3 με); for BWC + GLM, the difference of precisions between single and double processing for SNRs below 2.6 dB is about 1.5 °C (1.6 MHz or 35 με). In this case, double processing is more effective for all SNRs. The described technique’s potential application in structural health monitoring (SHM) of concrete objects and different areas in metrology and sensing were also discussed.

Published: April 2022

In clinical practice, the Ishak Score system would be adopted to perform the evaluation of the grading and staging of hepatitis according to whether portal areas have fibrous expansion, bridging with other portal areas, or bridging with central veins. Based on these staging criteria, it is necessary to identify portal areas and central veins when performing the Ishak Score staging. The bile ducts have variant types and are very difficult to be detected under a single magnification, hence pathologists must observe bile ducts at different magnifications to obtain sufficient information. This pathologic examinations in routine clinical practice, however, would result in the labor intensive and expensive examination process. Therefore, the automatic quantitative analysis for pathologic examinations has had an increased demand and attracted significant attention recently. A multi-scale inputs of attention convolutional network is proposed in this study to simulate pathologists’ examination procedure for observing bile ducts under different magnifications in liver biopsy. The proposed multi-scale attention network integrates cell-level information and adjacent structural feature information for bile duct segmentation. In addition, the attention mechanism of proposed model enables the network to focus the segmentation task on the input of high magnification, reducing the influence from low magnification input, but still helps to provide wider field of surrounding information. In comparison with existing models, including FCN, U-Net, SegNet, DeepLabv3 and DeepLabv3-plus, the experimental results demonstrated that the proposed model improved the segmentation performance on Masson bile duct segmentation task with 72.5% IOU and 84.1% F1-score.

Industry 4.0 is a new paradigm of digitalization and automation that demands high data rates and real-time ultra-reliable agile communication. Industrial communication at sub-6 GHz industrial, scientific, and medical (ISM) bands has some serious impediments, such as interference, spectral congestion, and limited bandwidth. These limitations hinder the high throughput and reliability requirements of modern industrial applications and mission-critical scenarios. In this paper, we critically assess the potential of the 60 GHz millimeter-wave (mmWave) ISM band as an enabler for ultra-reliable low-latency communication (URLLC) in smart manufacturing, smart factories, and mission-critical operations in Industry 4.0 and beyond. A holistic overview of 60 GHz wireless standards and key performance indicators are discussed. Then the review of 60 GHz smart antenna systems facilitating agile communication for Industry 4.0 and beyond is presented. We envisage that the use of 60 GHz communication and smart antenna systems are crucial for modern industrial communication so that URLLC in Industry 4.0 and beyond could soar to its full potential.
Automatic Speech Discrimination Assessment Methods Based on Event-Related Potentials (ERP)

Published: April 2022

Speech discrimination is used by audiologists in diagnosing and determining treatment for hearing loss patients. Usually, assessing speech discrimination requires subjective responses. Using electroencephalography (EEG), a method that is based on event-related potentials (ERPs), could provide objective speech discrimination. In this work we proposed a visual-ERP-based method to assess speech discrimination using pictures that represent word meaning. The proposed method was implemented with three strategies, each with different number of pictures and test sequences. Machine learning was adopted to classify between the task conditions based on features that were extracted from EEG signals. The results from the proposed method were compared to that of a similar visual-ERP-based method using letters and a method that is based on the auditory mismatch negativity (MMN) component. The P3 component and the late positive potential (LPP) component were observed in the two visual-ERP-based methods while MMN was observed during the MMN-based method. A total of two out of three strategies of the proposed method, along with the MMN-based method, achieved approximately 80% average classification accuracy by a combination of support vector machine (SVM) and common spatial pattern (CSP). Potentially, these methods could serve as a pre-screening tool to make speech discrimination assessment more accessible, particularly in areas with a shortage of audiologists.
Digitally Mediated Parenting: A Review of the Literature
Authors: Nichols Sue , Selim Nadia
Published: April 2022

The field of digital parenting is an emergent and dynamic area of research. This paper presents a structured literature review of research papers published between 2016 and 2021 which report empirical studies of parenting in the online space. Studies were sourced from Scopus and Web of Science using combinations of parent*/father/mother AND engage*/involve*/participat* AND online/digital*/virtual. A corpus of 144 papers were subjected to a first round of analysis, which resulted in the identification of two main clusters: Digital Parenting (Digi-P) and Digital Parental Involvement in Schooling (Digi-S). The first of these, constituting 92 papers, was the focus of a thematic analysis which is reported in this review. This review analysis is informed by theories of mediation in general, and parental mediation specifically. It finds that restrictive mediation was the most commonly reported parental approach to managing children’s online activities; that child age, gender, and vulnerability and parents’ ICT knowledge and experience impact on parents’ mediation practices; that children and parents have different perspectives and knowledge about children’s online activities; that parents’ online activities also impact on their children; and that parenting at a distance is supported by digital tools.
Assessment of Factors Impacting the Perception of Online Content Trustworthiness by Age, Education and Gender
Authors: Straub Jeremy , Spradling Matthew , Fedor Bob
Published: April 2022

Online content trustworthiness has become a topic of significant interest due to the growth of so-called ‘fake news’ and other deceptive online content. Deceptive content has been responsible for an armed standoff, caused mistrust surrounding elections and reduced the trust in media, generally. Modern society, though, depends on the ability to share information to function. Citizens may be injured if they don’t heed medical, weather and other emergency warnings. Distrust for educational information impedes the transfer of knowledge of innovations and societal growth. To function properly, societal trust in shared in information is critical. This article seeks to understand the problem and possible solutions. It assesses the impact of the characteristics of online articles and their authors, publishers and sponsors on perceived trustworthiness to ascertain how Americans make online article trust decisions. This analysis is conducted with a focus on how the impact of these factors on trustworthiness varies based on individuals’ age, education and gender.
Problematizing “Honour Crimes” within the Canadian Context: A Postcolonial Feminist Analysis of Popular Media and Political Discourses
Authors: Gill Jessica K.
Published: April 2022

Honour-based violence has garnered significant attention within Canadian national discourses, especially within popular media and political rhetoric. Frequently conceptualized as a culturally specific form of violence embedded with patriarchal understandings of honour, these crimes have been mobilized within mainstream media to vilify certain ethnic and racial communities, particularly from the Global East. Relying on ethnocentric explanations, honour crimes are imagined as foreign phenomena that have been imported into Canada by immigrant populations who actively resist assimilation and fail to adopt liberal Western values of equality and freedom. This paper seeks to unsettle these very tropes surrounding the “honour crime” label using a postcolonial feminist lens. Drawing on the murder case of Aqsa Parvez, this paper calls into question the discursive strategies used to construct “honour crimes” and the racialized tropes that they perpetuate. Further, this paper examines how this label is mobilized to carry out “political work” and support certain political agendas, which include managing immigrant populations.
Mathematical Modeling Suggests Cooperation of Plant-Infecting Viruses
Authors: Miller Joshua , Burch-Smith Tessa M. , Ganusov Vitaly V.
Published: April 2022

Viruses are major pathogens of agricultural crops. Viral infections often start after the virus enters the outer layer of a tissue, and many successful viruses, after local replication in the infected tissue, are able to spread systemically. Quantitative details of virus dynamics in plants, however, are poorly understood, in part, because of the lack of experimental methods which allow the accurate measurement of the degree of infection in individual plant tissues. Recently, a group of researchers followed the kinetics of infection of individual cells in leaves of Nicotiana tabacum plants using Tobacco etch virus (TEV) expressing either Venus or blue fluorescent protein (BFP). Assuming that viral spread occurs from lower to upper leaves, the authors fitted a simple mathematical model to the frequency of cellular infection by the two viral variants found using flow cytometry. While the original model could accurately describe the kinetics of viral spread locally and systemically, we found that many alternative versions of the model, for example, if viral spread starts at upper leaves and progresses to lower leaves or when virus dissemination is stopped due to an immune response, fit the data with reasonable quality, and yet with different parameter estimates. These results strongly suggest that experimental measurements of the virus infection in individual leaves may not be sufficient to identify the pathways of viral dissemination between different leaves and reasons for viral control. We propose experiments that may allow discrimination between the alternatives. By analyzing the kinetics of coinfection of individual cells by Venus and BFP strains of TEV we found a strong deviation from the random infection model, suggesting cooperation between the two strains when infecting plant cells. Importantly, we showed that many mathematical models on the kinetics of coinfection of cells with two strains could not adequately describe the data, and the best fit model needed to assume (i) different susceptibility of uninfected cells to infection by two viruses locally in the leaf vs. systemically from other leaves, and (ii) decrease in the infection rate depending on the fraction of uninfected cells which could be due to a systemic immune response. Our results thus demonstrate the difficulty in reaching definite conclusions from extensive and yet limited experimental data and provide evidence of potential cooperation between different viral variants infecting individual cells in plants.

Skin lesion assessment and management model: optimising existing resources in the management of non-melanoma skin cancer
Authors: O'Hare Caitlin , McKeough Michael , Hickson Melanie , Ferris Rebekah , Wiper Jay , Wagels Michael
Published: April 2022

**Background:** Skin cancer is a relatively common cancer in Australia with early diagnosis and simple treatment conferring a high likelihood of cure. The aim of this study was to implement a ‘see-and-treat’ clinic, using pre-existing infrastructure, to investigate whether this model of care would reduce waiting times and costs and give high levels of patient satisfaction. **Methods:** Inclusion and exclusion criteria based on suitability for day surgery treatment eligibility were developed in consultation with the hospital’s specialist anaesthetic service. Referrals were screened and those eligible underwent consultation with a plastic and reconstructive surgeon and same-day operative management with their choice of anaesthesia. Patients were reviewed one week and four weeks postoperatively. **Results:** Two hundred and six patients had 286 skin lesions removed over 23 operating lists. Over 75 per cent of excisions were on the face. Local anaesthetic with sedation was the most popular anaesthetic technique. There were 22 complications, and the incomplete excision rate was 4.2 per cent. The average waiting time for suitable patients reduced by 76 per cent, and category I outpatient waitlists were reduced by 100 per cent. An estimated gross saving of AU$1339 per patient was calculated. A survey of patients postoperatively showed all patients would recommend this model. **Conclusion:** This 'see-and-treat' model was shown to reduce waiting times and costs and provide high levels of patient satisfaction. It was also easily implemented using pre-existing infrastructure. It is a service that continues to be offered and expanded, with ongoing patient satisfaction.

Published: April 2022

Landfill leachate treatment by Reverse Osmosis (RO) system was evaluated in this study. Operational conditions of sand filters, sulfuric acid dosing and pH adjustment, cartridge filters and cat pumps, and membrane modules were discussed in detail. Advantages and challenges of RO for leachate treatment in developing countries handled with sustainability logic. The system has been successfully applied in leachate treatment with high removal rates as 98% of COD, 99% of total Nitrogen and suspended solids and substantial heavy metal removal. However, high costly operating expenses, dependency on the manufacturers for membranes, chemicals and other materials indicated the system unsustainable. Especially high-strength characteristic of leachate, high energy consumption of RO process, difficulty to struggle with scaling problems, limited lifetime of membranes and management/treatment of concentrate were expressed as the constraints of the system.
Five tests for risk-based approaches to national cybersecurity in resource-constrained environments
Authors:   Noran Shafik Fouad, Martin Ciaran
Published: April 2022

While we cannot currently accurately specify what good cybersecurity looks like, we can analyse what good risk-based approaches to national cybersecurity should aim at achieving. This is particularly important in low- and middle-income countries operating in resource-constrained environments in the early stages of economic development and digitalisation. This paper, therefore, discusses key considerations for risk-based cybersecurity by investigating the trade-offs that decision-makers should address so that scarce resources are best deployed to fend off threats that are more likely to happen and cause significant harm. The analysis is presented in the form of five tests that can be used to analyse the robustness of risk-based cybersecurity when resources are limited and to think about the potential paths that nations can take as they grapple with various economic and digitalisation challenges. As such, this framework does not present an exhaustive list of all the fundamental components of a cybersecurity strategy, but rather analyses the most important trade-offs and challenges that a cybersecurity strategy should address.

THREE FACES OF THE GOOD SOLDIER SCHWEIK
Authors: Pilar Martin
Published: April 2022

According to available information, it is still true that the most translated Czech novel is The Good Soldier Schweik (1921-23) by Jaroslav Hasek. By 2013, it had been translated into 58 languages. Schweik�s journey to the world began with translations into German, initially continuing mainly in the countries of the former Austro-Hungarian Empire and further in Russia and Ukraine. This artistic vision of war absurdities became widely known, especially after WWII and inspired such famous antimilitary works like Catch XXII by Joseph Heller, Slaughterhouse-Five by Kurt Vonnegut or the novels about Private Ivan Chonkin by Vladimir Voinovich. The character of Schweik is provocative and not easy to explain because from time to time, it is not easy to draw a line between idiotism and his common sense allowing him to survive almost everything. The attention of literary criticism is also often paid to Schweik�s specific way of thinking and narration that can be difficult for translating this novel to other cultural contexts. The quality of three English translations (1930, 1973, 1997-2007) differs to a considerable extent and, therefore, we will consider whether it is useful to offer innovated versions of classical texts to the reading public again and again.
SOME ASPECTS OF THE SCREEN DIGITAL READING IN THE CONTEMPORARY MEDIA LANDSCAPE GENERATION�S
Authors: Veinberg Sandra
Published: April 2022

Children are growing up in a digital environment and, from early on, they get used to watching films and images first and foremost, well before they learn to read. The screen keeps entertaining even very young �illiterate�. Slowly but steadily the screen becomes the child�s best friend and their main window onto the outside world, as determined by digital addiction. It contains moving pictures and is predominated by fascinating narratives. Therefore, within the framework of this study, it seemed important to find out how �screen kids� tend to read books and textual content. It is very likely that a transition from a moving picture to reading linear text may not be an easy process for �digital natives�. Our study proved that the screen offers reading which is based on the logic of audiovisual perception which requires a transition from linear text to audiovisual message with elements of visual storytelling. The audience perceives an visual story more readily than they do a linear text because �seeing is believing�. Therefore, it may gradually be necessary to supplement the existing textual journalism for children and young adults with a new form of media architecture on the internet which is more suited to �screen kids�.

This paper aims to highlight the impact that The Beatles have had over the generations on the lifestyle and self-image of individuals who listen to this music. This aspect leads to the creation of musical identities, which can reduce social-cultural barriers as well as language barriers between fans from different socio-cultural contexts. We want to highlight the fact that regardless of the cultural context in which people live, the quality of being a fan of a pop-rock band, can be a means by which people can reduce sociocultural and linguistic barriers. On the other hand, the impact of a band of such magnitude, such as The Beatles, can have strong, positive effects on various dimensions of lifestyle, shaping attitudes, values, behaviors. This can be a great resource for people who, in this increasingly individualized society, no longer have a sense of belonging to a community. Through social media they can adhere to such communities and indirectly to a number of values and behaviors that can have a positive impact on their lives. By interacting with these communities, they will develop a sense of belonging, shape their lifestyle and build a self-image that can sometimes, in certain circumstances, change life trajectories. In other words, the quality of being a fan of a band like The Beatles can be an extraordinary resource for society and can be means of resilience to various stressors of the socio-cultural environment in which we live.

The minimally invasive concept of treatment in clinical medicine and, in particular, in dentistry is associated with the introduction of pulp-saving treatment technologies into clinical practice. The aim of the study was to identify the reaction of the structure of pulp tissues in traumatic pulpitis in the experiment using various means and techniques of direct pulp capping. The experiment was carried out on male minipigs aged 4–5 months with deciduous dentition. Milk molars were selected for trepanation. After teeth preparation under anesthesia, the crowns of the first and second milk premolars were trepanned on the vestibular surface in the cervical region with pulp probing until bleeding. After bleeding has been stopped, the trepanation hole was closed with various preparations. For direct pulp capping we used mineral trioxide aggregate (MTA) — containing silicate material and glass ionomer cement (GIC). All samples of teeth with experimental pulpitis using MTA-containing materials (Rutdent), tricalcium silicate materials (Biodentin) and even GIC (Vitremer) did not reveal inflammatory changes in the pulp tissues when they were directly covered with various materials. Of all the experimental samples of pulpitis, inflammation was detected with a sample of the Rutdent material with fragment damage to the pulp. With traumatic pulpitis and the use of various materials for direct pulp capping, active reparative regeneration of pulp tissue was revealed. All studied materials contribute to the reparation of the pulp after damage and reduction of pulp inflammation.
THEEFFECT OF MELATONIN ON ELECTROLYTE AND WATER-RETENTION RENAL DYSFUNCTION IN CHRONIC ALCOHOL INTOXICATION ASSOCIATED WITH AUTOIMMUNE NEPHRITIS: AN EXPERIMENTAL RAT MODEL
Authors: Brin Vadim , Zemlianoy Vladlen
Published: April 2022

Autoimmune nephritis represents one of the frequent types of kidney pathology. With rates of alcohol consumption being on the rise, it is crucial to study the effects of alcohol abuse on the manifestations of nephropathy. Since the activation of lipid peroxidation plays a significant role in the formation of autoimmune and alcoholic nephropathy, it appears relevant to investigate the potential positive effects of a natural antioxidant, melatonin. The aim of the study was to investigate the effect of melatonin on renal function in chronic alcohol intoxication associated with autoimmune nephritis. Material and methods. The characteristics of changes in electrolyte and water excretory functions of the kidneys in Wistar rats with chronic alcohol intoxication associated with autoimmune nephritis were examined. Experimental chronic alcohol intoxication was obtained by daily intragastric injection through an atraumatic tube of 40% ethanol solution and the administration of isovaleric acid amide solution for 30 days. The model of autoimmune nephritis was obtained via a single subcutaneous injection of an emulsion of complete Freund's adjuvant with an equal volume of a mixture of kidney cortical homogenate at five points. Melatonin was administered intragastrically at a dose of 10 mg/kg for one month. Results. Alcohol intoxication was found to increase the degree of renal dysfunction in autoimmune nephritis. The administration of melatonin as a preventative agent led to a significant reduction in manifestations of nephropathy. Conclusions. Alcohol intoxication may exacerbate the manifestations of autoimmune nephritis. The administration of melatonin in chronic alcohol intoxication associated with autoimmune nephritis leads to the reduction in the severity of pathological changes in the electrolyte-excretory function of the kidneys.

Published: April 2022

COVID-19 is a disease that has spread throughout the world and is transmitted through inhalation or contact with droplets of infected people. The Indonesian Government has established a health protocol to reduce the spread of COVID-19, which is checking the body temperature of visitors at public places. The officers' representatives from public places are mobilized to check the body temperature of the visitors by bringing the thermometer closer to the forehead or hand of the visitors. This paper aims to design a contactless thermometer using an Arduino Uno by adding an interactive design and light installation. It aims to enhance the user-experience rather the design idea itself. The thermometer will move a mechanical flower adjusted by the temperature measurement with this product design.

SEMANTIC FEATURES OF THE ENGLISH, RUSSIAN, KAZAKH AND UZBEK PROVERBS WITH A “FRIEND” CONCEPT
Authors: KAMBAROVA Marjan
Published: April 2022

The article deals with proverbs containing the concept of “friend” in the English, Russian, Kazakh and Uzbek languages to determine universal and national-specific features. The proverb is characterized by the completeness of thought, which expresses linguistic and speech characteristics and shows the importance of preserving the cultural and, in general, national values of the people. It is a generalized thought with a didactic bias. Proverbs with a notion of “friend” in the studied languages show that friendship is a universal phenomenon for all people. A friend is, first of all, a person who shares both happy moments of life and sad ones with his/her friend. The universal feature of proverbs with the concept friend in the studied languages is that a true friend is a friend in trouble. And the national specificity in these proverbs is expressed by different lexemes and notions. In English the notion friend is conveyed by the word friend. In Russian — by the word друг. In the Uzbek and Kazakh languages — by the words doʻst (дос), oʻrtoq (ортақ). In the Uzbek and Kazakh languages there are words dugona and құрбым to address a female friendwhereas the word əріптес is used for both men and women. The analysis and description of the semantic properties of proverbs was carried out using such methods as semantic-stylistic, descriptive and comparative.

The curriculum is the most important part of the field of education, if there is no curriculum, learning may not be carried out properly. In this Covid-19 pandemic, the government through the Ministry of Education and Culture is working to ensure that learning can run well even though learning can be carried out online. The latest policy issued by the government is an emergency curriculum in education units under special conditions. The emergency curriculum is a simplification of the existing curriculum without reducing the substance and learning itself. The implementation of the emergency curriculum during the Covid-19 pandemic had a good influence on learning activities. Learning is a learning activity that is facilitated by teachers so that it can improve and develop cognitive aspects that improve thinking power and increase students' knowledge. The respondents in this study were shown to students, students, teachers and lecturers. This study aims to explore information regarding the use of the emergency curriculum in improving the quality of learning during the Covid-19 pandemic. The data collection technique used is through an e-questionnaire with google forms. The results of the study can show that the emergency curriculum can improve the quality of learning during the Covid-19 pandemic.
Hyperchaos, adaptive control, synchronization, and electronic circuit design of a novel 6D hyperchaotic convective dynamo system
Authors: Kopp Michael
Published: April 2022

In this work, a new nonlinear dynamic (6D) system of equations is proposed that describes the process of magnetic field generation. This system of equations is an alternative to the Rikitake dynamo system describing chaotic magnetic field reversals.

The behavior of the new dynamical system is studied by analyzing the stability of equilibrium points. For fixed parameters of the 6D dynamical system, the spectrum of Lyapunov exponents and the Kaplan-York dimension are calculated. The presence of two positive Lyapunov exponents demonstrates the hyperchaotic behavior of the 6D dynamical system. The fractional Kaplan-York dimension indicates the fractal structure of strange attractors. We have shown that an adaptive controller is used to stabilize the novel 6D chaotic system with unknown system parameters. An active control method is derived to achieve global chaotic synchronization of two identical novels 6D chaotic systems with unknown system parameters.

Based on the results obtained in Matlab-Simulink and LabVIEW models, a chaotic signal generator for the 6D chaotic system is implemented in the Multisim environment. The results of chaotic behavior simulation in the Multisim environment show similar behavior when comparing simulation results in Matlab-Simulink and LabVIEW models.
