Международная защита прав в сфере информационных отношений (на примере практики европейского суда по правам человека)

The features of international protection of rights in the information relations field are investigated. Modern information technologies form new types of public relations, the object of which is information. Information has an impact on all spheres of human activity and generates information relations that are in constant dynamics and development, as new information technologies appear, new types and methods of information transmission and protection are created. The article analyzes the international legal basis of information relations. Special attention is paid to the analysis of the practice of the European Court of Human Rights. The norms of the European Convention for the Protection of Human Rights and Fundamental Freedoms of 1950, devoted to freedom of expression, are considered. It was found that sometimes it is extremely difficult to determine the degree of potential threat to human rights and freedoms, and often this is the cause of judicial errors on the part of national courts and become a reason for applying to the European Court of Human Rights. Special attention is paid to the consideration of judicial practice concerning relations arising on the Internet, the activities of online mass media (online newspapers, information portals, etc.), as well as a completely new case of cyberstalking. The practice of the European Court of Human Rights shows that free media space and the right to information are the foundation of any democratic society. Maintaining a balance between public and private interests, a person's right to respect for their private life and the right to express their opinion is extremely important in a modern state governed by the rule of law

Smart Machinery Monitoring System with Reduced Information Transmission and Fault Prediction Methods Using Industrial Internet of Things

A monitoring system for smart machinery has been considered to be one of the most important goals in recent enterprises. This monitoring system will encounter huge difficulties, such as more data uploaded by smart machines, and the available internet bandwidth will influence the transmission speed of data and the reliability of the equipment monitoring platform. This paper proposes reducing the periodical information that has been uploaded to the monitoring platform by setting an upload event through the traits of production data from machines. The proposed methods reduce bandwidth and power consumption. The monitoring information is reconstructed by the proposed methods, so history data will not reduce storage in the cloud server database. In order to reduce the halt time caused by machine error, the proposed system uses machine-learning technology to model the operating status of machinery for fault prediction. In the experimental results, the smart machinery monitoring system using the Industrial Internet of Things reduces the volume of information uploaded by 54.57% and obtains a 98% prediction accuracy.

Comparison Between Problem-Based Learning and Lecture-Based Learning: Effect on Nursing Students' Immediate Knowledge Retention.

BackgroundThe basic role of teaching at any degree of training is to bring a rudimentary change within the student. To facilitate the method of information transmission, educators ought to apply acceptable teaching strategies that best suit specific objectives and outcomes. Identifying the best method through comparison of problem-based learning (PBL) and the lecture method; so as to improve students’ overall academic performance appear to be important.ObjectiveThe aim of the study was to undertake comparison between problem-based and lecture-based learning methodologies for immediate knowledge retention of nursing students at Dire Dawa University.MethodsQuantitative research method which used a pre-experimental two group pretest and post-test research design was employed to identify effective teaching methods for immediate knowledge retention on 38 nursing students from June 1 to June 15, 2019. The students were grouped randomly into problem-based learning and lecture methods. The pretest-posttest analysis was done after an intervention made: a two-hour lecture and four-hour problem-based learning accordingly. Content validity ratio and content validity index was conducted for authentication of instruments and Cronbach alpha was computed to verify its reliability. A paired t-test was conducted to identify mean score change, and p<0.05 was cut off value to determine if there is a significant mean change in the posttest.ResultBoth methods showed significant knowledge score improvement (t=13.6, p< 0.001) for lecture-based method and (t=11.302, p< 0.001) for problem-based learning. But as compared to the lecture method, problem-based learning has little effect on students’ immediate knowledge retention, and 63.2% of the nursing students prefer the lecture method as the best teaching method.ConclusionThe lecture method is the best teaching method for immediate knowledge retention for nursing students; it is also the most preferred method of teaching method by the students.

Development of a method for wireless information transmission in wells equipped with sucker rod pump units

Oil lifting via sucker rod pump units is the most widespread way to extract oil reservoir products. Complications adversely affecting the operation of downhole equipment and entailing increased wear and premature failure of sucker rod pump units arise in the process of high-viscosity oil production. The pressure and temperature of the well fluid are the main parameters for assessing changes in the properties of the extracted products and for determining the static level of the liquid column. It is possible to control pressure and temperature using sensors located in the immediate vicinity of the well pump. Today, a wired channel is the main way of transmitting the measured data to the well mouth. The present work proposes a new technical solution for a wireless communication channel along tubing strings and rods. The columns are separated by asphaltenes deposits on the surface of the columns and centralizers mounted on the rods. The rod string isolation from the tubing string at the wellhead is carried out through suspension modernization. Columns are closed inside the pump, specifically, on the cylinder-plunger contact. Information is transmitted from the bottom by means of a submersible module, consisting of an electrical separator and electronic circuit. The latter controls the separator closure and opening. The results of measurements of the resistance between the columns indicate the possibility of implementing a communication channel.

Single Sideband Hartley Amplitude Modulation

It is developed a method of information transmission with application of amplitude Single Sideband Hartley modulation (SSBH) allowing to increase of radio channel length for optical and fiber optic signal transmission systems where single sideband amplitude modulation (SSB) is used. Increase of communication range is provided due to application a sum of two orthogonal oscillations of the same frequency as a carrier (Hartley wave). It provides energy gain in 6 dB and 1.41 times increase of the amplitude of output signal of synchronous detector comparing to SSB in case of the same radiation power of transmitter and the same sensitivities of SSBH and SSB signals receivers. Application of SSBH and SSB modulation allows to provide the energy gain in transmitting channel approximately 15–20 times comparing to amplitude modulation (AM) application. It also provides increased security of SSBH transmission since in case of absence of modulation signal the transmitter does not radiate, that allows to provide energy saving in case of transmitter power supply with battery. Depending on the need we can use both upper and lower side bands.

СИНТЕЗ СПЕКТРАЛЬНО ТА ЕНЕРГЕТИЧНО-ЕФЕКТИВНИХ СИГНАЛЬНО-КОДОВИХ КОНСТРУКЦІЙ ДЛЯ СИСТЕМ МІМО З ПРОСТОРОВИМ КОДУВАННЯМ СИГНАЛІВ

Wireless communication systems are considered, the main task of which is to increase their spectral (SE) and energy efficiency (EE) in conditions of limited frequency and energy resources. Additional use of the spatial resource based on flexible and universal methods of signals Space-Time Coding (STC) in MIMO-systems (Multiple Input - Multiple Output) can significantly increase the SE and EE values, as well as significantly improve the capabilities and conditions for EE exchange on SE. The advantages and disadvantages of Orthogonal Space-Time Block Coding (OSTBC) and Non-Orthogonal STBC (NOSTBC) are shown. Two main methods of synthesis of spectrally and energy-efficient information transmission methods are demonstrated. The first method is implemented by creating Perfect-codes that simultaneously achieve maximum diversity and multiplexing gains. The exponential computational decoding complexity of such codes makes it impossible for their practical implementation in mobile terminals at the present stage of development of circuitry. The second method of synthesis is based on improving the simple basic STC methods in terms of increasing the SE and EE by creating Signal-Code Constructions (SCC), which have the advantages of the basic STC methods and are devoid of the disadvantages inherent in Perfect-codes. A technique for the synthesis of SCC is proposed, the essence of which is to determine the priority areas (by the value of the Signal-to-Noise Ratio (SNR)) of using the STC and corresponding signal constellations, which provide the maximum SE for a guaranteed Bit Error Rate (BER). It was found that MIMO 2x2 with Alamouti OSTBC has an advantage in terms of EE over NOSTBC type VBLAST for SE not more than 8 b/s/Hz and SNR under 35 dB, BER not exceeding 10-5. In MIMO 4x4, OSTBC codes are inferior to NOSTBC in terms of EE. VBLAST code allows to provide SE 4 - 8 b/s/Hz at SNR 10 - 20 dB, BER not exceeding 10-5. Based on the results obtained, propositions for further improvement of OSTBC and NOSTBC are formulated.

High-Data-Frequency-Ratio Information Transmission Method for Fast Dynamic Response SWPIT Systems Based on DASK Modulation

Integration of power and information transmission is promising for simultaneous wireless power and information transmission (SWPIT). This article presents a differential amplitude-shift keying (DASK) modulation-based high-data-frequency-ratio information transmission method for fast dynamic response integrated SWPIT systems. Modeling and analyses of the phase-shifting modulation of power converters indicate the potential of the DASK modulation for information transmission. Operation principle of the proposed modulation is established to maintain the stability of power transmission based on the modeling. Modulator, demodulator, and communication protocol are further designed. Using the dynamic analytical model of the transmission channel, the active intersymbol interference (ISI) elimination characteristics are analyzed. Due to the ISI elimination, a high-data-frequency-ratio and fast dynamic response SWPIT is realized. Interactions between power and information transmissions are evaluated, and the results show anti-interference performances. Finally, an experimental prototype rated at 200 W is built to verify the effectiveness of the method, and the data–frequency ratio reaches 0.5 bit/Hz. Complexity, cost, and response period of the method are reduced significantly, and it can be extended to other applications universally.

Analysing the efficiency and robustness of gossip in different propagation processes with simulations

This paper uses the probability theory to analyse the ultimate consistency of the gossip protocol propagation process by dividing it into two phases. The time complexity and information complexity of the flooding, tree and gossip methods are compared by simulation with different variants. Also, three ways of communication between nodes in the network are introduced: only-push, only-pull, and push-and-pull. The paper analysed the simulated results of variable nodes using those three ways and discussed their corresponding time and information complexity. The simulations and analysis compared performances of information transmission under different transmission loss rates and concluded that the push-and-pull has an effect on transmission structure robustness. Finally, an effective method of information transmission was proposed to deal with transmission loss.

Development and application of a specification-compliant highway tunnel facility management system based on BIM

Recent decades have seen a dramatically increasing pace of highway tunnel construction in China. The continuous growth of highway tunnels creates a challenge to facility management (FM) to ensure a safe and reliable operation of the tunnels. The FM is complicated by the poor operation environment, long design life, and long geographical distribution of the tunnels. This study aims to develop a specification-compliant FM system based on Building Information Modeling (BIM) using the Lingxia tunnel in Wenzhou, China as a testbed. The critical FM information capture, category, integration and transmission methods are discussed. The data structure of the responsible personnel, process and product for each FM task is developed. The system framework is designed to consist of five modules including project documentation, personnel and contactors, FM plan and execution, technical performance evaluation, and safety and emergency management. The Chinese industry specifications for highway tunnels are implemented and interpreted with a computer-processable format into the system. This research contributes to the body of knowledge by describing one of the first few pilot applications of the BIM-based tunnel FM and identifying the challenges encountered. The application of the system in the mountainous tunnels in China demonstrates the feasibility and benefits of the BIM-based FM related to productivity improvement.

A GaN-Based Wireless Power and Information Transmission Method Using Dual-Frequency Programmed Harmonic Modulation

Information transmission is often required in power transfer to implement control. In this paper, a Dual-Frequency Programmed Harmonic Modulation (DFPHM) method is proposed to transfer two frequencies carrying power and information with the single converter via a common inductive coil. The proposed method reduces the number of injection tightly coupled transformers used to transmit information, thereby simplifying the system structure and improving reliability. The performances of power and information transmission, and the method of information modulation and demodulation, as well as the principles of the control, are analyzed in detail. Then a simulation model is set up to verify the feasibility of the method. In addition, an experiment platform is established to verify that the single converter can transfer the power and information simultaneously via a common inductive coil without using tightly coupled transformers.

Blind Source Separation Algorithm for Chaotic Masking Multipath Signals Based on Spectral Peak Search Counter Permutation

Since voice communication is the main method of information transmission, it is important to ensure the safety and efficiency of voice communication. In this paper, a more complex multipath channel model in a wireless environment is considered, and chaotic masking technology is used to ensure the security of voice signal transmission. Based on this, a multipath blind source separation algorithm based on cross-correlation permutation of spectral peak search counters is proposed. First, chaotic masking is performed between multiple voice signals and chaotic signal, and an impulse response filter is used to simulate the multipath transmission process. Next, the short-time Fourier transform is employed to convert the observation signal into a frequency-domain signal. Then, the joint approximate diagonalization of eigen-matrix algorithm is used to perform linear instantaneous blind source separation at each frequency. And to solve the permutation uncertainty problem in the frequency domain method, a cross-correlation permutation algorithm based on a spectral peak search counter is proposed. Finally, the permuted signal is transformed back to the time domain to get the estimated source signal by the inverse short-time Fourier transform. And simulation experiments show that the algorithm greatly reduces the calculation amount of the autocorrelation coefficient in the traditional permutation algorithm. Moreover, the permutation algorithm has stability and accuracy, and provides a solution for the secure transmission and effective separation of voice signals in multipath transmission channels.

Assembly Method for Satellite Device Installation based on HoloLens

As the satellite design changes from the traditional 2D mode to the 3D digital mode, the satellite assembly also enters the 3D assembly mode. An effective and accurate device installation process information transmission method from designers to operators is not formed, and accidents with incorrect polarity in device installation often occur. In order to improve efficiency and quality of satellite device installation, modelling method of R point of device is regulated and a system based on HoloLens is designed. With the help of the system, the code and R point are clear at a glance, so an ordinary operator can verify the polarity correctness of the device installation and the efficiency can be doubled.

DEFINING THE INTEGRATIVE COMMUNICATIVE SPACE AS A FACTOR INFLUENCING THE LINGUO-METHODOLOGICAL STRATEGY FOR TEACHING RUSSIAN AS A FOREIGN LANGUAGE

Modern sociocultural interaction tools and technologies bring forth multiple information transmission forms and methods, which in its turn leads to the emergence of new mono- and multi-code communication systems that intrinsically differ from verbal or creolized texts. Among the category features of the communication field are, on one hand, its universality resulting from the global nature of Internet resources and, on the other, its diffuseness determined by the simultaneous incorporation and synergy of the real and virtual language environment, which exert a special impact on the language personality. The authors understand the successful development of the secondary language personality as the development of the learner’s multilinguistic and multicultural personality, i.e. the combination of linguistic and cultural fluency and professional speaking skills. It is directly and closely dependent, in terms of methodology, on the awareness of the existing relationship between the “natural” language order and various semiotic ways of explaining the totality of national distinctions and values and the methodological interpretation of the present-day integrative communicative space. A competent organization of the language learning process, based on the integrated communication environment, will blur the boundary between in-class and natural communication, will provide foreign learners with the opportunity to acquire, through various channels of communication, the necessary communication experience to be effectively engaged in sociocultural, academic and professional activities in the Russian language. It will also contribute a deeper understanding of the Russian linguistic culture as an integral part of the global value paradigm.Keywords: real and virtual language environment, information and communication resources, online space, secondary language personality, language learning strategy.

ЛИНГВОКУЛЬТУРОЛОГИЧЕСКАЯ ИНФОРМАТИВНОСТЬ УСТНОГО АНГАРСКОГО ТЕКСТА: КОД МАЛОЙ РОДИНЫ

Statement of the problem. The article deals with the problem of linguacultural and ethnical informativeness of the oral text as a macro-unit of traditional regional linguoculture; the types of texts about the small homeland are revealed depending on the dominant textual function and the peculiarities of the cultural meanings expression. The purpose of the article is to characterize the ethno-cultural concept “small motherland” as a macrounit of the Northern Angara linguoculture and the most important element of the linguocultural information of the oral text, to identify the basic conceptual and axiological features of this concept. The methodology of the research is a directed interview (at the stage of collecting empirical material); linguacultural analysis of the text and conceptual analysis (at the research stage). Research results. It is revealed that oral texts about the small motherland reflect and translate the value-semantic code of the linguacultural community of Angara Siberians. According to the dominant textual functions and methods of linguacultural information transmission, oral texts about the small motherland are divided into explicative, descriptive, appellative and mixed. All texts are emotive, because they are based on the emotional and semantic dominant – the idea of a small motherland as the highest spiritual value. Geographical, social and ethical components of the concept “small motherland” are revealed. It is established that in its structure the axiological layer is vividly represented. This layer is explicated by linguistic and stylistic means. Conclusion. Oral texts about the small motherland have a high degree of linguacultural informativeness, because they reflect the value picture of the world and explicate the images of consciousness peculiar to the mentality of the Russian original residents of Siberia. In the texts about the small motherland three modes of world transformation are reflected: emotional-sensual, spiritual and aesthetic. It is established that in these texts only a positive assessment of the small homeland is transmitted, which is thought and experienced as an organic part of the large linguacultural space of the “own”, called the big homeland, the Fatherland. “Small motherland” as a place of birth, native land is an important unit of the conceptosphere of traditional linguaculture. This concept has existential significance not only for the individual, but also for the entire linguacultural community; it accumulates a non-linguistic cultural environment, forms a solidarity sense of patriotism.

Impact of climate change cognition on public willingness to pay for environmental protection and mitigation actions

Based on Chinese General Social Survey(CGSS) 2010 data, we use Ologit regression model to describe and analyze the influencing factors of public willingness to pay for environmental protection and emission reduction behavior. The empirical results show that the residents' overall willingness to pay for environmental protection and emission reduction are not high. At the same time, the willingness to pay for environmental protection is higher than the willingness to reduce emissions, which indicates that in order to protect the environment, the public is more willing to bear certain losses economically than to take environmental protection actions inconvenient to life. Climate change cognition has a significant positive impact on the willingness to pay for environmental protection and emission reduction behavior, and the impact of climate change cognition on environmental protection willingness is more significant than the emission reduction behavior. In addition, it is also found that income, religious beliefs and regions have a significant impact on the public's willingness to pay for environmental protection; age, education, media use, urban and rural residential areas and areas have significant impact on public emission reduction behavior. According to these conclusions, some suggestions are put forward to improve the public's environmental awareness level by using modern information transmission methods and various opportunities to strengthen publicity, and to adjust the public's behavior choices through fiscal, taxation, credit and subsidies.
