The positive side sees criticism as learning and encouragement of improvement for business actors, while the negative side views it as adversely affecting Nyak Kopsah's business reputation. The majority of informants are in the Negotiate position, accepting the dominant ideology but resisting its full implementation. They recognized the importance of honest criticism of food quality and prices for consumer information, but adjusted their views based on personal experience and social environment. In addition, they emphasized that the way in which criticism is delivered by Codebluu must be considered so as not to cause excessive negative effects.

포스트 시네마 환경에서의 관객 현전에 관한 연구

This study defines the diversified media environment of contemporary visual art as a post-cinema environment and analyzes how the spatial expansion of the screen and the conceptual transformation of the camera have occurred within it. By examining the altered methods of image production, mediation, and reception, the research reveals the presence of the spectator as a noncorporeal subject in the visual field of image experience. The changes in the screen and the audience have been driven by the transition to multi-screen and multimedia environments, leading to a transformation in visual perception through physical environments that interact with images in expanded spaces. Additionally, the post-cinema camera, as a non-human agency, has broadened the scope of image production and mediation through computer imaging processes and digital technologies. It not only intervenes between the unexperienced realities beyond human cognition and the audience as the experiencing subject, but also produces and mediates images for machines as machine vision, facilitating the process of converting representation into information. Furthermore, this study argues that the issue of spectator presence in the visual field can be understood through the paradox of absence and presence in the technological context of 21st-century media. It asserts that the spectator emerges as an “electronic body” that transcends the physical body in the image reception environment. The concept of the audience's electronic body introduces perspectives on the coding and informatization of the body due to technological interventions by computers and media, as well as the hybrid sensations resulting from the interaction between bodies and devices, proposing a new notion of corporeality for non-corporeal subjects in the new media environment.

Broadband multi‐carrier linear frequency modulation signal reception with subcarrier frequency offset deramp processing

AbstractIn this paper, a broadband multi‐carrier linear frequency modulation (LFM) signal reception method with subcarrier frequency offset deramp processing is proposed and investigated. The proposed frequency offset deramp processing is implemented by mixing the multi‐carrier LFM radar echo with a multi‐carrier LFM reference that has a different subcarrier frequency interval. With this design, the sampling rate of the radar receiver is remarkably reduced and crosstalk‐free separation of different subcarrier signals is easily conducted in the frequency domain. To fuse the multiple subcarriers and fill the frequency gaps, a sparse reconstruction method is employed to obtain the broadband response, which is essential for achieving high range resolution detection. The effectiveness of the proposed method is validated through an experiment in which the reception of an 8‐carrier LFM signal is conducted and a total bandwidth of 6 GHz after multi‐carrier fusion is demonstrated. An inverse synthetic aperture radar imaging experiment is also conducted with the results verifying the good potential of the proposed method in practical applications.

Control Mechanism and Noise Reduction Effect of CVDM on Rail Transit Steel Bridge: Experimental and Numerical Study

Steel bridge, as one of the main structural types in bridge design, has been widely used in rail transit. However, the train-induced vibro-acoustic problem of the bridge has become increasingly prominent. The vibration and noise characteristics must be more significant and complex than steel truss bridge because of too many components. Viscoelastic damping materials (VDMs) have the characteristics of both viscous liquid and elastic solid, and have better damping performance than other damping materials. Therefore, VDM plays an important role in vibration and noise reduction technology. In applications, VDM is usually combined with constraining materials to form composite viscoelastic damping materials (CVDM). In this paper, based on the dynamic receptance method and superposition principle, the coupling model of vehicle–track–bridge in the frequency domain is first established, and then the vibration and noise prediction model of a steel truss bridge with CVDM is established based on RUK theory and statistical energy analysis (SEA) method. Based on the prediction model, the natural dynamic characteristics of typical components of steel truss bridges with CVDM were investigated, and the control mechanism and influence rule of CVDM on train-induced vibration and noise of steel bridges were revealed.

Smart reception: An artificial intelligence driven bangla language based receptionist system employing speech, speaker, and face recognition for automating reception services

In recent times, service robots (SR) have become widely accepted in a variety of fields as an alternative to traditional reception methods. Artificial Intelligence (AI) driven systems are seen as efficient labor alternatives, resulting in several SR models already being developed, primarily designed for English-speaking environments. Despite a large Bangla-speaking population, the exploration and implementation of Bangla language support within AI reception systems remain unexplored due to limited resources, posing significant challenges for deployment. This study presents a novel AI-enabled receptionist framework tailored to Bangla-speaking environments, addressing the limitation of Bangla language resources for developing automated reception systems. Leveraging advanced AI technologies including Face Recognition, Speaker Recognition, Automatic Speech Recognition (ASR), Text-to-Speech Synthesis, and Question Answering System, our integrated system demonstrates promise to automate Bangla reception systems. Our suite of models yields positive performance, with a face recognition accuracy of 99.38%, a speaker recognition system with 5.83 Equal Error Rate (ERR), ASR model achieving a Word Error Rate (WER) of 9.005%, TTS model scoring a Mean Opinion Score (MOS) of 4.10, and a question-answering system with a validation loss of 0.03%. Real-world evaluation among 1664 users in a university setting achieved over 75% user satisfaction, with 88% expressing interest in real-life implementation, showcasing usability across different domains. Limitations such as limited training data, scalability, and environmental sensitivity persist, underscoring the need for further development. Nevertheless, our framework demonstrates potential for real-life implementation, fostering human-robot interaction in Bangla-speaking contexts and paving the way for future innovations in AI-driven Bangla receptionist systems.

Low complexity sub-baud rate sampling reception in a bandwidth-limited IM/DD system.

This Letter presents what is to our knowledge a novel approach to reduce the digital signal processing (DSP) complexity in intensity modulation and direct detection (IM/DD) systems, which is critical for short-reach optical communication systems with severe bandwidth limitations. We propose a sub-baud rate sampling reception method utilizing a polyphase feedforward equalizer-based maximum likelihood sequence estimation (PFFE-MLSE), which could operate effectively under a sampling rate of 0.6 samples per symbol. This new architecture eliminates the need for resampling, allowing the adaptive equalizer to operate with significantly reduced complexity-over 60% compared to traditional FFE-MLSE. An offline experiment, transmitting a 100-Gbaud on-off keying (OOK) signal over a 5-km single-mode fiber (SMF) link, demonstrates the feasibility of our approach with bit error ratio (BER) meeting the KP4-forward error correction (KP4-FEC) threshold in the optical back-to-back (OBTB) scenario and 7% hard-decision FEC (HD-FEC) threshold in the 5-km SMF transmission.

Energy efficiency optimization of NB-IoT using integrated Proxy & ERAI technique

The 3rd Generation Partnership Project (3GPP) standardized the NarrowBand Internet of Things (NB-IoT) technology in Release-13, aiming to support applications requiring minimal device power consumption, efficient small data transfer, and tolerance for delays. This paper provides two major contributions: first, it characterizes the NB-IoT architecture and its enhancements in subsequent 3GPP releases; second, it introduces an energy-saving technique for NB-IoT user equipment based on semi-Markov processes. Integrating a Proxy state and an enhanced release assistant indication (ERAI), the proposed technique improves upon the traditional Discontinuous Reception (DRX) method in the NB-IoT standard. This novel approach reduces energy consumption during low data communication, distinguishing it from other power-saving methodologies. The effectiveness of this technique is assessed through the power-saving factor (PSF) under various conditions, such as different eDRX durations (T_eDRX), PSM durations (T_PSM), DRX cycle periods (T_ACTIVE+T_SLEEP), and DRX active periods (T_ACTIVE). Our findings confirm that the proposed Proxy & ERAI technique significantly boosts the power-saving capabilities of NB-IoT devices, especially for small data packet transmissions. Theoretical and simulation results indicate that the PSF can be enhanced by up to 99.4% with optimized eDRX durations (T_eDRX) and up to 99.9% with optimized PSM (T_PSM) durations. These results underscore the significant energy-saving potential of our proposed technique, making it highly effective for NB-IoT applications with low data transmission needs.

Echo characteristics of pulsed lasers in non-uniform smoke environments

This work establishes a pulsed laser backscattering echo signal model based on an improved semi-analytical Monte Carlo method. The developed model is applied in non-uniform smoke environments to mitigate the smoke interference of laser fuzes for ground proximity detection. The model considers variations of the photon step size according to the concentration of the smoke environment, and the computational speed is accelerated by implementing an improved semi-analytical reception method. The proposed echo signal model is employed to investigate the effects of smoke-related parameters and laser detection system parameters on the backscattering echo waveform of smoke. Finally, the model is validated based on experiments. The results show that the intensity of the smoke backscattering echo and the emission pulse width approximately conform to a logarithmic relationship. Specifically, the echo intensity is positively correlated with the emission pulse width, and the ratio of the time between the rising edge and the falling edge of the echo signal is positively correlated with the pulse width. Meanwhile, the intensity of the smoke backscattering echo and the distance between the transmitter and receiver approximately adopt an exponential relationship. Herein, we describe the characteristics of a laser backscattering echo in a non-uniform smoke environment. The results can guide future research regarding laser fuze detection methods and strategies relevant for ground targets in smoke environments.

Improving the Reliability and Accuracy of Population Receptive Field Measures Using a Logarithmically Warped Stimulus.

The population receptive field method, which measures the region in visual space that elicits a BOLD signal in a voxel in retinotopic cortex, is a powerful tool for investigating the functional organization of human visual cortex with fMRI (Dumoulin & Wandell, 2008). However, recent work has shown that population receptive field (pRF) estimates for early retinotopic visual areas can be biased and unreliable, especially for voxels representing the fovea. Here, we show that a 'log-bar' stimulus that is logarithmically warped along the eccentricity dimension produces more reliable estimates of pRF size and location than the traditional moving bar stimulus. The log-bar stimulus was better able to identify pRFs near the foveal representation, and pRFs were smaller in size, consistent with simulation estimates of receptive field sizes in the fovea.

“CONFESSIONS” BY J.-J. ROUSSEAU: TECHNIQUES OF AESTHETIC INFLUENCE AND STRATEGY OF READER’S RECEPTION

The study aims to explore the specific features of the modern reception of J.-J. Rousseau’s “Confessions”. The theoretical framework of the research is grounded on the ideas advanced by T. Avtuxovych, M.Czermińska, M.Głowiński, W.Iser, R. Jakobson, H.R.Jauss, P.Lejeune, Yu. Lotman, V.Tjupa, Zh. Starobinskiy and other scholars. The researchers describe the semiotic model of literary communication and the theory of the text by Yuri Lotman. The research was conducted using historic-functional, hermeneutic, receptive, and theoretical analysis methods. An attempt is made in this paper to show how the process of “decoding” the meanings intended by the author in the text takes place. In particular, the authors study how Rousseau’s “Confessions” functions in the structure of modern literary communication. The specific objectives of the present study are the meanings of “Confessions” are read by the contemporary recipient and which ones are relegated to the background compared to the literary communication of the eighteenth century. The common discourse code of the author and the reader is the key to successful communication and understanding of the specifics of the project of Rousseau’s life writing. At the same time, the success and specificity of artistic communication are influenced by the difference in discourse code meanings related to the time distance between the author and the recipient and the layering of new historical and cultural patterns in the reader’s consciousness. At the thematic level, three main themes are considered, including: a) the social origin of the autobiographical subject, b) his conflict with society, and c) the protagonist’s intimate self-disclosure. Thus, the article provides a detailed examination of the motif of the social origin of the autobiographical character. On the topic of the social origin of the character, instead of the plebeian’s right to public attention for the contemporary reader, the value of education and knowledge, freedom of speech and individual liberty are being actualised. Of particular note is the theme of the conflict between a character and society, the idea of the human right to otherness, the right to personal liberty and the right to choose the concept of one’s own life comes to the forefront. Thus, a literary text realises the social function of literature. The reading of the character’s self-disclosure by an attentive reader (from Rousseau’s contemporary to modern readers) has a twofold purpose: first, to encourage everyone to live the experience of the character and thus to think about themselves, and second, to reflect on society as a whole. It testifies to the fact that in the aspect of self-disclosure of the meaning of “Confessions”, the transformation of confession as an external form of a religious rite of repentance addressed to God into the narrative genre of confessional autobiography addressed to a human reader of the story is actualized. The study demonstrated a need for continuation of the study in the aspect of reader reception to contribute to the perception of its place in the contemporary literary and cultural space.

Indicators of Quantity and Performance Efficiency of Ball Reception by High-Quality Football Players in Competitive Conditions

The aim of this study is to establish indicators of the quantity and effectiveness of various ball reception techniques by high-quality football players. Material, participants and methods: the research was conducted from December 2023 to February 2024. Technical-tactical actions (ball receptions) were recorded during games of English Premier League (EPL) teams in the 2023/2024 season. A total of 10 games were registered and analyzed for this study. The methods employed included analysis of scientific and methodological literature, video analysis of matches, and mathematical statistical methods. Results: the study revealed that football players from English Premier League teams in the 2023/2024 season, on average, executed 370,9±35,3 ball receptions per game. This consisted of 337,4±34,2 rolling ball receptions and 33,5±1,8 airborne ball receptions. Additionally, players performed, on average, 280,8±27,3 ball receptions with the inside of the foot, 40,1±5,1 with the sole, 31,8±3,2 with the outside of the foot, 8,1±0,9 with the chest, 3,9±0,5 with the thigh, 3,8±0,5 with the middle part of the shin, 1,5±0,2 with the abdomen, and 1,1±0,2 with the head. The most effective method of ball reception in the recorded games was using the sole (99,1±0,4%), while the least effective was with the head (59,7±12,0%). Conclusions: the study established indicators for the quantity and effectiveness of ball reception techniques by high-quality football players. Statistical differences were found in both quantitative and qualitative aspects of various ball reception techniques among EPL teams in the 2023/2024 season. It was established that the most popular way of receiving the ball is receiving the ball with the inner side of the foot, and the least popular is receiving the ball with the stomach and head. It was also established, the effectiveness of ball reception by football players depends on the technique used and the trajectory of the ball.

SiPM joint likelihood reception for mobile LED-optical communication under pointing errors.

Light-emitting diode (LED)-optical communication is a novel spectrum communication with wide field of view (FOV), light weight, and long-distance free-space capabilities. Due to atmospheric turbulence attenuation and pointing errors caused by long-distance communication, this Letter proposes a multi-pixel channel joint maximum likelihood (JML) reception method using a highly sensitive silicon photomultiplier (SiPM). To evaluate the performance of the SiPM under mobile terminal jittering communication, we analyze the effect of optical transmitting power, pointing errors, and signal-to-noise ratio (SNR) gain on optical communication by comparing JML with signal channel using the maximum likelihood (ML) algorithm. Both simulation analysis and experimental results demonstrate that the proposed JML algorithm to process signals received from SiPM multi-pixel channels can effectively mitigate the impact of pointing errors on the bit error rate (BER) of optical communications by two orders of magnitude at large jitter radians and SNR.

All-in-One BPSK/QPSK Switchable Transmission and Reception for Adaptive Free-Space Optical Communication Links

Adaptive free-space optical (FSO) communication links have been extensively studied in order to adapt to variable atmospheric channel environments due to factors such as atmospheric turbulence. As a supporting technology, an all-in-one BPSK/QPSK switchable transmission and reception method is proposed and experimentally demonstrated for adaptive modulation format switching in FSO links. The transmission and reception of both modulation formats are realized based on the same IQ modulator and single-photodetector coherent receiver. Simulation and experimental results show that the QPSK signal has a power penalty of about 3–4 dB compared to the BPSK signal with a BER of about 1 × 10−3. The basis for format switching is given according to the various atmospheric channel conditions. The proposed method provides a flexible and efficient solution for variable FSO communication environments to improve their performance.

Coded Excitation for Ultrasonic Testing: A Review.

Originating in the early 20th century, ultrasonic testing has found increasingly extensive applications in medicine, industry, and materials science. Achieving both a high signal-to-noise ratio and high efficiency is crucial in ultrasonic testing. The former means an increase in imaging clarity as well as the detection depth, while the latter facilitates a faster refresh of the image. It is difficult to balance these two indicators with a conventional short pulse to excite the probe, so in general handling methods, these two factors have a trade-off. To solve the above problems, coded excitation (CE) can increase the pulse duration and offers great potential to improve the signal-to-noise ratio with equivalent or even higher efficiency. In this paper, we first review the fundamentals of CE, including signal modulation, signal transmission, signal reception, pulse compression, and optimization methods. Then, we introduce the application of CE in different areas of ultrasonic testing, with a focus on industrial bulk wave single-probe detection, industrial guided wave detection, industrial bulk wave phased array detection, and medical phased array imaging. Finally, we point out the advantages as well as a few future directions of CE.

All-Fiber Low-Modal-Crosstalk Demultiplexers for DSP-Free IM/DD LP-Mode MDM Transmission

Weakly coupled mode-division multiplexing (MDM) techniques supporting intensity modulation and direct detection (IM/DD) transmission are promising methods of enhancing the capacity of short-reach scenarios in which low-modal-crosstalk-mode demultiplexers for degenerate linear polarized (LP) modes are highly desired. In this paper, we review two degenerate-mode reception schemes. Firstly, a low-modal-crosstalk orthogonal combined reception method for degenerate modes is proposed based on all-fiber mode-selective couplers, in which signals in both degenerate modes are demultiplexed into the LP01 mode of single-mode fibers and then are multiplexed into the mutually orthogonal LP01 and LP11 modes of a two-mode fiber (TMF) for simultaneous detection. Secondly, a novel degenerate-mode-selective coupler consisting of an input few-mode fiber and an output TMF is proposed, which could demultiplex degenerate LP modes without any digital signal processing (DSP). Both demultiplexers are achieved based on the taper and polish process. The fabricated devices are characterized and compared. The results show that the proposed schemes can pave the way to the practical implementation of DSP-free IM/DD LP-mode MDM transmission systems.

Implementation of OPC UA for Machine-to-Machine Communications in a Smart Factory

The development of autonomous and intelligent robots in manufacturing plants is being made possible by advancements in communications technologies and the Industrial Internet of Things (IoT). These autonomous devices are capable of gathering data from several sensor devices and multiple linked device systems through the use of OPC UA communication protocols. These devices can transmit and receive enough data these days to allow them to make decisions. Organization of individual devices is the sole application where high-level decision-making powers are available; communication between devices only entails low- level processing. The purpose of these images is to increase the OPC UA protocol-enabled devices' communication capabilities. This involves choosing methods for data reception and processing between devices connected vertically (deeper devices) and horizontally (equal devices). Because of this, the energetic gadget device makes the manufacturing facility site visitors better. KEYWORDS: Internet of things, Machine, Communications, Enterprises, Protocols, OPC UA protocols

Vibration transmission analyses of double-layer cylindrical shell with fully immersed elastic connections through experimental and analytical approaches

This paper investigates vibration transmission characteristics of the double-layer cylindrical shell with fully immersed elastic connections through experimental and analytical approaches. A test sample of the double-layer cylindrical shell connected by six vibration isolators is firstly manufactured and a forced vibration test is done with fully immersed interlayer. Meanwhile, a novel analytical approach is developed to calculate vibration responses of an unequal double-layer cylindrical shell with fully immersed elastic connections. The substructure receptance method and wave propagation method are combined in the coupling theoretical model. Springs are utilized to simulate elastic connections, that are considered as substructures. By comparing the achieved analytical and experimental vibration responses, good agreements are gained and the two approaches are demonstrated. Then the transmission characteristics are gradually analyzed with respect to the double-layer shell with elastic connections, double-layer shell with interlayer fluid and double-layer shell with fully immersed elastic connections. It is found that the interlayer water between the inner and outer shells plays a “short-circuit” role in vibration transmission, which greatly reduces the isolation performance of vibration isolators. Nevertheless, the fully immersed isolators with small stiffness still have the non-ignorable vibration isolation effect compared with the case of rigid connection.

Selecting the Best Music for the Moment in a Music and Imagery Session

Music and Imagery (MI) is a receptive music therapy method within the Continuum Model of Guided Imagery and Music developed by Lisa Summer. In receptive music therapy, clients listen to music for therapeutic purposes. The unique part of the MI method is that the client’s own music can be used. Three qualified music therapists from two countries trained together in the MI method and were grouped together for supervision. Moving away from the traditional therapist-client dyad model, we worked as a trio, with the third person in our trio actively witnessing the session and sharing her perspectives and reflections during the post-session discussion. This article focuses on discussing our experiences in selecting music for our individual processes, since this selection is the new concept in the MI method, called the transition. To report our experiences, we chose to use trioethnography. Each author told her own story, whilst the others took part actively in a small intervision group as critics, friends, and colleagues. In this way, we acknowledged each other’s processes as clients, therapists, and witnesses. Our experience of using intervision to explore the new concept of transition (choosing music) and reporting on that process using trioethnography was very positive. It became clear that intervision can be meaningful for all music therapists in clinical settings, and that trioethnography should be further explored as a research approach.

ПСИХОТЕРАПЕВТИЧЕСКОЕ ВОЗДЕЙСТВИЕ НА ПСИХОЭМОЦИОНАЛЬНОЕ СОСТОЯНИЕ ДЕТЕЙ И ПОДРОСТКОВ С ОНКОПАТОЛОГИЕЙ С ПОМОЩЬЮ МУЗЫКОТЕРАПИИ

The need to study the impact of art therapy, in particular music therapy, on the psycho-emotional state of children and adolescents with cancer is dictated by the high prevalence of mental disorders during hospitalization. Purpose: to analyze the literature to study the impact of music therapy on the psycho-emotional state of children and adolescents with cancer during treatment. General information. The most common symptoms experienced by children and adolescents undergoing treatment for cancer are depression, anxiety, pain associated with diagnostic procedures and treatment, nausea and fatigue, sleep disturbances and fatigue. Variations of art therapy using active and receptive methods of music therapy effectively influence the psycho-emotional status of patients, help children get rid of feelings of fear and cope with their anxiety, promote wellness, stress management, pain relief and more. The use of music therapy methods normalizes the psychosomatic state. The goal of psychotherapeutic work with adolescents and children with cancer is, first of all, prevention and correction of psychopathological reactions. Timely psychotherapy provided to cancer patients in childhood will help harmonize the psycho-emotional state associated with the treatment, especially after mutilating operations. The technique is universal and integrative; it can be successfully used in the treatment of many psychological disorders, as well as integrated and combined with other therapeutic approaches (body-oriented approach, drawing, dance-movement method, etc.). To reduce the incidence of mental pathology after illness and achieve its maximum compensation, a multidisciplinary approach is required.

Biaxial Excitation and Reception Method Applied to Ultrasound Imaging.

The biaxial method consists of the utilization of orthogonal electric fields in single-element piezoceramics both in transmission and reception. This study demonstrates the application of the biaxial method to broadband transducers. We developed a three-element biaxial transducer array to demonstrate the feasibility of biaxial method in imaging applications. Finite element analysis was used to model the response of a single transducer element. An electric characterization was performed at each transducer element to determine their driving frequency. Each transducer was driven at 6.25 MHz and tested in different phases to determine the phase that produced the maximum pressure amplitude and shortest pulsewidth. Both simulations and experimental results showed that the acoustic pressure and half-pulsewidth followed a sinusoidal response as a function of the difference in phase applied to the lateral electrodes, as it has been described in our previous work. An imaging test was performed by placing a 0.36-mm diameter nylon wire 20 mm away from the transducer while driving and receiving each element with different combinations of conventional and biaxial driving. By applying a biaxial rephasing at the receiving electrodes during the data analysis, we obtained a maximum reduction in the axial resolution from 4.6 to 1.3 mm and signal-to-noise ratio (SNR) improvements from 15.2 to 24.4 dB, when compared to conventional driving.
