Vibration Control of a Two-Link Flexible Robot Arm with Time Delay through the Robust Receptance Method

This paper proposes a method for active vibration control to a two-link flexible robot arm in the presence of time delay, by means of robust pole placement. The issue is of practical and theoretical interest as time delay in vibration control can cause instability if not properly taken into account in the controller design. The controller design is performed through the receptance method to exactly assign a pair of pole and to achieve a given stability margin for ensuring robustness to uncertainty. The desired stability margin is achieved by solving an optimization problem based on the Nyquist stability criterion. The method is applied on a laboratory testbed that mimic a typical flexible robotic system employed for pick-and-place applications. The linearization assumption about an equilibrium configuration leads to the identification of the local receptances, holding for infinitesimal displacements about it, and hence applying the proposed control design technique. Nonlinear terms, due to the finite displacements, uncertainty, disturbances, and the coarse encoder quantization, are effectively handled by embedding the robustness requirement into the design. The experimental results, and the consistence with the numerical expectations, demonstrate the method effectiveness and ease of application.

ADMINISTRATIVE LAW AGAINST AN INFECTIOUS DISEASE EPIDEMIC: SELECTED PROBLEMS IN THE CONTEXT OF THE SARS-COV-2 CORONAVIRUS (COVID-19 DISEASE)

The article discusses the legal and administrative regulations regarding the prevention and control of infectious diseases. The author puts forward and justifies the thesis that the SARS-CoV-2 coronavirus epidemic (COVID-19 disease) has exposed significant imperfections (and partly deficiencies) of the above-mentioned regulations, and at the same time revealed the effects of – sometimes insufficient – theoretical reflection on administrative law and the methods of reception of its assumptions and theoretical structures into the provisions of this law. Against this background, particular attention was paid to the construction of the special state as a (separate and independent) institution of material administrative law, as well as to issues concerning, inter alia, administrative regulations, general administrative acts, administrative enforcement of non-pecuniary obligations, administrative proceedings, criminal-administrative law, and social (digital) exclusion in administrative law. The considerations are summed up by the statement that administrative law – both in practical and theoretical terms – has turned out to be insufficiently prepared for an epidemic of an infectious disease in general, and even more so for an epidemic of a scale such as that caused by the SARS-CoV-2 coronavirus.

Effectiveness of music therapy for autism spectrum disorder, dementia, depression, insomnia and schizophrenia: update of systematic reviews.

BackgroundMusic therapy (MT) aims at maintaining, restoring and furthering physical/emotional/mental health. This review assesses effectiveness of MT and its methods for autism spectrum disorder (ASD), dementia, depression, insomnia and schizophrenia.MethodsA search for systematic reviews and health technology assessment reports was conducted and yielded 139 hits. Given the large amount, we focused on five frequent diagnostic groups with available Cochrane reviews. A second search was conducted in four databases. Two authors independently performed study selection, data extraction and assessed methodological quality. Only trials with moderate/low risk of bias (RoB) were selected.ResultsTen randomized controlled trials (1.248 participants) met inclusion criteria. For schizophrenia, no studies with low/moderate RoB were found; therefore, updating was not possible. The Cochrane authors stated that quality of life (QoL), social functioning, global/mental state improved for schizophrenia, but not global functioning. For ASD, MT improved behaviour, social communication, brain connectivity and parent–child relationship. For depression, mood was enhanced, and for insomnia, sleep quality, stress, anxiety, total sleep time, disease severity and psychological QoL improved. MT positively affected mood, neuropsychiatric behaviour, apathy, communication and physical functions for dementia; behavioural/psychological symptoms improved only in severe, and memory and verbal fluency only in mild Alzheimer’s disease. Cognition improved for dementia in one of four studies. Both active (playing music) and receptive (listening to music) methods were used for dementia, whereas for ASD and depression, active methods were applied. For insomnia, only receptive methods were used.ConclusionThese findings provide evidence that MT helps patients improving their physical/psychosocial health. More research investigating long-term effects is needed.

A receptance method for partial quadratic pole assignment of asymmetric systems

A new receptance method is proposed for partial quadratic pole assignment problem (PQPAP) of asymmetric systems with multi-input. We use receptance matrices of symmetric parts of open-loop systems to express the solution of PQPAP. Then we derive the sensitivities of changed eigenvalues of close-loop system and give the measure of robustness. On these grounds, an algorithm for solving the robust and minimum norm PQPAP is put forward. Our method utilizes receptance matrices of symmetric parts of asymmetric systems and it is applicable to the systems with multi-input. Finally, numerical results are given to show the efficiency of our method.

If napkins could talk: women’s action sketching at the Ballets Russes

ABSTRACT Action sketches hold vast communicative potential as windows into the historical details of dance events. This article foregrounds sketchbook images depicting ballet dancers created in the 1910s by British artist Laura Knight (1877-1970) and French artist Valentine Hugo (1887-1968) to show how the quick line drawings inscribed during live performances translate nuances of spectator-performer dynamics. Analyzing various instances of women’s action sketching serves to elevate the activity as an independent form of artistic expression alongside established visual cultural practices such as painting. Knight’s and Hugo’s geographically distinct yet thematically coinciding works prove that action sketching does more than draft silhouettes: it forms a network of microcosms which enhance perceptions of the time, place, and atmosphere of dances and their surroundings. By advocating for a deep reading of the sketch as a major dance reception method, I highlight the ways ballet audiences saw their emotional and material conditions reflected onstage in the early twentieth century. Ultimately, I argue that a serious consideration of the woman spectator as an active participant in theatrical dance performance, through her own artistic practice, is indispensable to building a more holistic view of ballet’s role in reinventing the modernist subject-object relationship.

Evaluation of the Increased Share of Tax Revenues from Government Revenues Using the Approach of Oil Dependency Reduction

This quantitative research was conducted with a positivist paradigm to evaluate the methods that could increase tax revenues from government revenues using oil dependency reduction. The researcher used the annual data of Iran during 1978-2019 to analyze the research model. In addition, a generalized torque technique was applied in the EViews software to estimate the model. According to the results, the variable of oil revenues had the most significant effect on the government revenues, followed by the revenue of sales and consumption tax and value-added tax (VAT), indicating that the government could easily reduce oil revenues by efficient policies and replace this source of income with the revenue from sales and consumption tax and VAT. On the other hand, the revenue from wealth tax had the least significant impact on the government revenues, which was possibly caused by the inefficiency of reception methods or the inability to be identified. Further assessment in this regard could help governments identify extremely more appropriate revenue resources to extract less oil and control social inequity. An important issue observed in this study was the reverse coefficient of the revenue from corporate tax. Most of these companies may be manufacturing and industrial units, and given the pressure of economic and political issues and inflation on the country, they have mostly reacted to enormous taxes, had tax evasion, or reduced their production level, which has, in turn, increased the rate of unemployment and decreased the national gross domestic product, thereby reducing the government revenues.

Asymmetrical clipping optical filter bank multi-carrier modulation scheme

Filter bank multi-carrier (FBMC) is considered a promising alternative to the Orthogonal Frequency Division Multiplexing (OFDM) scheme. It improves spectral efficiency by eliminating the need for cyclic prefix while attenuating interference due to the robustness of the out-of-band emission. In this work, we present a framework, and the performance evaluation of FBMC is a multi-carrier modulation scheme for the direct detection of optical communications. As the proposed model has higher spectral efficiency than the classical ACO-OFDM, as removing the guard interval enhances the spectral efficiency. Furthermore, the perfect rectangular pulse shaping and eliminating the out of band emission of the filter bank enhances the ACO-FBMC the BER performance of the ACO-OFDM. We propose a transceiver model for Asymmetrical Clipped Optical FBMC (ACO-FBMC) based on Fast Fourier Transform (FFT) operations, analyze inter-frame interference, and offer an iterative receptive method to eliminate it. Finally, we compared the bit error rate (BER) performance of the ACO-FBMC using different overlapping factors with the ACO-OFDM.

Three roads diverged: Transformative self-experience in AMT and GIM

ABSTRACT Introduction: The analytical music therapy (AMT) blended learning program through Molloy College and the Bonny method of guided imagery and music/focused music imagery (GIM/FMI) training through the Therapeutic Arts Institute provide advanced training in music psychotherapy approaches. Both programs require self-experience and supervision prior to working with clients in each respective model. Method: Utilizing the active improvisational method of AMT, as well as the receptive method of GIM in separate, alternating sessions, this article highlights the processes and experiences of pivotal moments as they emerged in both models. Results: At the time of publication, the primary author was moving through self-experience in AMT and also receiving personal GIM sessions and experienced profound, pivotal moments. The insights gained and subsequent life changes that occurred are attributed to alternating and integrating processes in both clinical models. Discussion: The experiences are examined from the perspective of the trainee, the AMT therapist, and the GIM therapist, and symbolic analyses of the improvised music and imagery processes embedded in the respective psychoanalytic and humanistic/transpersonal orientations.

A receptance method for robust and minimum norm partial quadratic eigenvalue assignment

This paper considers the partial quadratic eigenvalue assignment problem (PQEAP) in active vibration control using state feedback. A receptance method is proposed for PQEAP such that the norms of feedback matrices and the condition number of close-loop system are simultaneously minimized. The real form of the proposed method is developed. The proposed method only uses receptance matrices and the unwanted eigenpairs of open-loop system. The system matrices and the unchanged eigenpairs of open-loop system are not required. The efficiency of the proposed method is illustrated by some numerical examples.

Optimal Multi-Antenna Transmission for the Cooperative Non-Orthogonal Multiple-Access System

We investigate the beamforming for the multi antenna cooperative non-orthogonal multiple access (NOMA) system, where an access point (AP) delivers messages for multiple user terminals (UT) with successive interference cancellation (SIC) reception method. Some UTs with multiple antennas cooperate with the AP transmission to improve the diversity and the average power performance. We formally present two optimal beamforming schemes at the AP and at the cooperative UTs. One scheme has no power limitation for the cooperative UTs, while the other one does have such limitation. We guarantee that the rank one beamformer is sufficient to achieve the optimal points so that the proposed schemes have rank one semi-definite programming (SDP) structure. Simulation results show the performance gain of the multi-antenna cooperative NOMA schemes in the sense of diversity and the average power.

Lightweight Feature Enhancement Network for Single-Shot Object Detection.

At present, the one-stage detector based on the lightweight model can achieve real-time speed, but the detection performance is challenging. To enhance the discriminability and robustness of the model extraction features and improve the detector’s detection performance for small objects, we propose two modules in this work. First, we propose a receptive field enhancement method, referred to as adaptive receptive field fusion (ARFF). It enhances the model’s feature representation ability by adaptively learning the fusion weights of different receptive field branches in the receptive field module. Then, we propose an enhanced up-sampling (EU) module to reduce the information loss caused by up-sampling on the feature map. Finally, we assemble ARFF and EU modules on top of YOLO v3 to build a real-time, high-precision and lightweight object detection system referred to as the ARFF-EU network. We achieve a state-of-the-art speed and accuracy trade-off on both the Pascal VOC and MS COCO data sets, reporting 83.6% AP at 37.5 FPS and 42.5% AP at 33.7 FPS, respectively. The experimental results show that our proposed ARFF and EU modules improve the detection performance of the ARFF-EU network and achieve the development of advanced, very deep detectors while maintaining real-time speed.

The Effects of Musical Therapy on Parkinson’s Patients

Parkinson's disease is a progressive neurodegenerative disorder that affects motor skills and mobility. Despite the studies conducted to find the treatment of this disease continues, there is no definite treatment yet. Besides the treatment to control and slow down the disease, patients also need the support of different methods and psychosocial interventions. Music therapy, as one of these supportive interventions, has been found to have positive effects supported by current studies. Positive improvements are achieved in the general well-being of the patients with effects such as rhythm follow-up by active or receptive methods, affect and socialization created by the authorities. There are many studies in which music and rhythmic sounds are used to prevent loss of balance and, therefore, the risk of falling. Many studies investigating the effects of music therapy for Parkinson's patients have found that it has positive effects on improving the motor skills of patients, preventing balance disorders and the risk of falling, ensuring psychological well-being, and socializing many people with the same problems in studies that apply music therapy as a group. In this study, which compiles the general effects of music therapy in Parkinson's patients, the results of current studies will be shared.

A High Spatiotemporal Resolution Ultrasonic Ranging Technique With Multiplexing Capability

In this article, a high-performance water-coupled ultrasonic ranging technique is presented. We improved the conventional time-of-flight (ToF) ranging technique based on digital correlation of pseudorandom noise (PRN) waveforms by introducing signal carrier phase shift detection with an I/Q coherent reception method. In this way, the spatial resolution is dominated mainly by the digitization resolution of the analog-to-digital converter (ADC) used in the receiver circuit. Submicrometer resolution is achieved in the entire full-scale-range (FSR) while keeping the ADC sampling rate at the Nyquist sampling limit of the carrier frequency of ranging signal. In this study, we use quadrature amplitude modulation (QAM) waveforms of a set of 1023-bit GPS Gold codes with 8 MHz carrier as a ranging signal. Experiments carried out in a water vessel reveal micrometer-level accuracy and precision for quasi-static and dynamic cases. It is experimentally illustrated that the proposed method is capable of multiplexing. The optimal ranging performance is approached by selecting an appropriate set of systemic technical parameters and ranging signals. This allows to define the figure of merit (FOM) indicating the performance upper bound of such a ranging system.

Poems by V. Bryusov “Native Language” and G. Tukai “Tugan Tel”


 In literary criticism, structural and semantic correspondences are established between the author and the reader as elements of aesthetic reality. As a result, another text appears before us, different from the original one. With each new reading, a new edition of the text will appear. In this regard, the question of determining the subjective and objective factors of the reception process becomes important. The tasks set determined the need to refer to a comparative analysis of the poems of Russian and Tatar poets, during which the regularities of the functioning of new meanings emerging in interliterary dialogues are considered. Comparative, hermeneutic and receptive methods of analysis were used in solving the set tasks. As a result of the study, the similarities and differences between the works of V. Bryusov and G. Tukai, dedicated to the topic of the native language, were established, and the peculiarities of perception of the additions of foreign literature by bilingual readers were also identified. The results obtained are significant in the study of the role of the reader as a subject of interliterary dialogues.
