Piano automatic transcription based on transformer
Authors: Wang Yuan
Published: September 2023

Recent years, research on automatic music transcription has made significant progress as deep learning techniques have been validated to demonstrate strong performance in complex data applications. Although the existing work is exciting, they all rely on specific domain knowledge to enable the design of model architectures and training modes for different tasks. At the same time, the noise generated in the process of automatic music transcription data collection cannot be ignored, which makes the existing work unsatisfactory. To address the issues highlighted above, we propose an end-to-end framework based on Transformer. Through the encoder-decoder structure, we realize the direct conversion of the spectrogram of the collected piano audio to MIDI output. Further, to remove the impression of environmental noise on transcription quality, we design a training mechanism mixed with white noise to improve the robustness of our proposed model. Our experiments on the classic piano transcription datasets show that the proposed method can greatly improve the quality of automatic music transcription.
An power and bound-aware optimised scheduler for virtualized cloud computing
Authors: Senthil Kumar K. , Anandamurugan S.
Published: September 2023

Cloud computing has become a crucial paradigm for large-scale data-intensive applications, but it also brings challenges like energy consumption, execution time, heat, and operational costs. Improving workflow scheduling in cloud environments can address these issues and optimize resource utilization, leading to significant ecological and financial benefits. As data centres and networks continue to expand globally, efficient scheduling becomes even more critical for achieving better performance and sustainability in cloud computing. Schedulers mindful of energy and deadlines will assign resources to jobs in a way that consumes the least energy while upholding the task’s quality standards. Because this scheduling involves a Non-deterministic Polynomial (NP)-hard problem, the schedulers are able to minimize complexity by utilizing metaheuristic techniques. This work has developed methods like Artificial Bee Colony (ABC), Genetic Algorithm (GA), and Particle Swarm Optimization (PSO) for optimizing the scheduler. Local search and exploration are respectably supported by heuristic algorithms. The algorithm’s exploration and exploitation features must also be balanced. The primary objective is to optimize computation-intensive workflows in a way that minimizes both energy consumption and execution time while maximizing throughput. This optimization should be achieved without compromising the Quality of Service (QoS) guarantee provided to users. The focus is on striking a balance between energy efficiency and performance to enhance the overall efficiency and cost-effectiveness of cloud computing environments. According to the simulation findings, the suggested ABC has a higher guarantee ratio for 5000 jobs when compared to the GA, PSO, GA with the longest processing time, and GA with the lowest processing time, by 7.14 percent, 4.7 percent, 3.5 percent, and 2.3 percent, respectively. It is observed that the proposed ABC possesses qualities like high flexibility, great robustness, and quick convergence leading to good performance.

Published: September 2023

BACKGROUND:

Renal cysts are the most frequently occurring incidental renal lesions. They are asymptomatic, which explains why they tend to be diagnosed incidentally as a result of imaging tests. In cases where malignancy is suspected, there are various therapeutic alternatives.

OBJECTIVE:

The objective of this study is to review the diagnostic and therapeutic alternatives for cystic renal lesions.

METHOD:

A systematic search was conducted in Pubmed, Science Direct, Scopus, and Google Scholar databases between May and October 2022. The review of articles was conducted following the methodological recommendations of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 Statement. As a result, 25 articles were selected.

RESULTS:

Thirteen studies focused on diagnostic management. In five of the cases ultrasound was used, multiparametric magnetic resonance imaging (mpMRI) was considered in six articles, and computerized tomography (CT) was studied in three. Eleven papers were retrospective series, one of the studies was prospective, and one was a simulated cost-effectiveness model. Among the 12 articles on treatment, five focused on surgery and one on the results of active surveillance, while three compared active surveillance with other treatments. Four articles assessed the percutaneous approach and radiofrequency ablation. All articles were retrospective cohorts.

CONCLUSIONS:

CT is the most standard of the tests. In doubtful cases, mpMRI and ultrasound can serve as complementary tests. Partial nephrectomy is currently the gold standard treatment and the results are similar for both open and laparoscopic approaches. Percutaneous radiofrequency treatments produce reasonable survival rates free of local recurrence and metastasis and are recommended in patients with high surgical risk.

Published: September 2023

BACKGROUND: Machado Joseph Disease (MJD) is an autosomal dominant neurodegenerative disease. In previous studies, we described significant bilateral horizontal Vestibulo-Ocular Reflex (VOR) deficit within this population without any reference to the presence of vestibular symptomatology. OBJECTIVE: To evaluate whether, beyond cerebellar ataxia complaints, MJD patients have typical vestibular symptomatology corresponding to the accepted diagnostic criteria of Bilateral Vestibulopathy (BVP) according to the definition of the International Barany Society of Neuro-Otology. METHODS: Twenty-one MJD, 12 clinically stable chronic Unilateral Vestibulopathy (UVP), 15 clinically stable chronic BVP, and 22 healthy Controls underwent the video Head Impulse Test (vHIT) evaluating VOR gain and filled out the following questionnaires related to vestibular symptomatology: The Dizziness Handicap Inventory (DHI), the Activities-specific Balance Confidence Scale (ABC), the Vertigo Visual Scale (VVS) and the Beck Anxiety Inventory (BAI). RESULTS: The MJD group demonstrated significant bilateral vestibular impairment with horizontal gain less than 0.6 in 71% of patients (0.54±0.17). Similar to UVP and BVP, MJD patients reported a significantly higher level of symptoms than Controls in the DHI, ABC, VVS, and BAI questionnaires. CONCLUSIONS: MJD demonstrated significant VOR impairment and clinical symptoms typical of BVP. We suggest that in a future version of the International Classification of Vestibular Disorders (ICVD), MJD should be categorized under a separate section of central vestibulopathy with the heading of bilateral vestibulopathy. The present findings are of importance regarding the clinical diagnosis process and possible treatment based on vestibular rehabilitation.
MODELLING AND CAICULATIONS OF THE OXIGEN REGIME DURING THE EXTRACTION OF IRON FROM GROUNDWATER BY FILTRATION
Authors: Obertas Iryna
Published: September 2023

On the base of the simplification of the general mathematics models of the iron removal the engineer calculation methods of the removing of the iron combinations from the ground waters by the filtration on the refine filters and at the well filter colmatation are proposed. The analysis and the comparative value of the proposed methods are carried out.

In most regions of Ukraine, aquifers, from which water is finly taken for the population, have an increased iron content, which significantly exceeds the standarts.

Is modern conditions, the most widespread method of extracting compounds from waters is filtering through granular loading from natural or artificial granular materials in special installations, the main element of which is a filter.

Under normal conditions in groundwater in the absence of dissolved oxygen and other oxidizing agents, dissolved iron is mainly present in the form of Fe2+ ions or its unstable protective forms of various salts. When interacting with dissolved oxygen, which is fed into the water, divalent iron is oxidized to trivalent, and then hydrolyzed into lumpy or suspended iron hydroxide in the form of silt flakes.

On the basis of the implementation of a more general mathematical problem and the performance of the comparative analysis carried out tat the same time, the article proposes calculation methods that allow assessing the influence of the oxygen regime. The perfomed analysis shoved that in condition of oxygen deficiency, a simpler model can be adopted. Taking into account that in the case of a homogeneous filter, a more intense accumulation of sludge occurs in the upper layers, then an important characteristic during design and operation is the determination of the concentration of the amount of sludge near the upper border of the filter.
ANALYTICAL APPROACH IN THE ANALYSIS AND OPTIMIZATION OF CRANES DYNAMIC LOADS DURING THEIR START-UP: SWINGING THE LOAD
Authors: Chovnyuk Yurii , Cherednichenko Petro , Ostapushchenko Olga , Kravchenko Igor
Published: September 2023

During the operation of the cranes pendulum swings of the load are observed. They cause cranes or cargo carts uneven movement, additional loads on power ele-ments of cranes, create inconvenience during their operation. This must be taken into account during detailed cranes calculations. 

In bridge, gantry and some other standard types of cranes which move along a rail path, load pendulum oscillations frequency relative to the crane is significantly lower than the elastic oscillations frequency of the crane metal structure and the movement mechanism transmission. Therefore, the load pendulum oscillations can be considered practically independent from the crane elastic oscillations and when cal-culating them, the metal structure and movement mechanism transmission can be taken as absolutely rigid. In this study to determine the dynamic loads acting on the metal structure and the movement mechanism transmission, the law of ropes tension hori-zontal component change, which arises as a result of the load pendulum oscillations, is given in the form of a known time function, which is determined according to the scheme of an absolutely rigid crane. This approach allows to reduce the order of mo-tion equations of the crane dynamic system by two units. In accordance with the above, the calculation of pendulum oscillations of the load on a ropes can be carried out ac-cording to the simplest two-mass scheme. This is exactly the approach implemented in the study. Motion conditions and equations of the “cargo cart − the load on a rope” system analytically determined, at which dynamic loads in the rope/elastic element have the smallest (minimum) values in the starting mode of the bridge-type crane.

English-Ukrainian intersemiotic translation within the configuration of modes of modality in literary texts
Authors: Holubenko N. I.
Published: September 2023

The article highlights the main features of intersemiotic translation of a literary text, which is considered to be an expression of the author’s modality as a set of signs of various semiotic systems. Thus, the purpose of the study is to determine the linguistic and non-linguistic means of expressing modality in a literary text, the specifics of their interaction to generate meaning, and the features of their reproduction in intersemiotic translation. The object of modality in translation within a literary text is a set of signs encoded by the author of the source text and organized into a system that is decoded and reproduced by the translator both at the phonological, lexical, and syntactic levels and the semantic, emotional, and associative ones. The analysis of the category of modality from the standpoint of semiotics in literary texts involves decoding semiotic resources, symbols, and signs, taking into account the individual author’s, social, political, cultural, and national contexts. The process of interpreting and reproducing the sign configurations of individual author modality is carried out at the syntactic, semantic, and pragmatic levels to achieve the corresponding aims. Thus, at the first stage, the forms and interactions of determinants are defined and interpreted whereas the second level involves consideration of the internal semantic plane of the research object, and, accordingly, at the third level, the influence and use of signs are outlined. It is proved that adequate literary translation is carried out based on the multimodality of the text that is viewed as a multimodal communication, within which meaning is generated by the configuration of different semiotic sign systems that require interpretation according to the principle of optimal relevance and creativity. The central concept of translation is semiosis as a process of interpretation of a sign and generation of meaning, that indicates the relationship of the sign with the outside world.

Досліджено що, на сьогоднішній день процес побудови в Україні соціально-захищеної та політично-стабільної моделі суспільства займає важливе місце реалізація реформ у галузі охорони здоров‘я, яка представляє собою основу для збереження людських ресурсів держави. Зазначено, що наразі, формується тенденція до підвищення вартості надання медичних послуг через підвищення кваліфікаційного рівня лікарів та впровадження у медичну сферу інноваційних технологій, що, відповідно, зумовлює зростання вимог громадян щодо якості таких послуг. З’ясовано, реалізація програми щодо функціонування абсолютно нової системи надання первинної медичної допомоги. Її суть полягає у прямій залежності заробітної плати лікаря загальної практики сімейної медицини, чи педіатра, від кількості його пацієнтів. Визначено, що ситуація в Україні з обмеженістю обсягів бюджетних коштів, що виділяються для фінансування ефективного функціонування системи охорони здоров‘я, призводить до неможливості підвищення якості надання медичних послуг громадянам. Спираючись на науковий доробок дослідників стану реалізації механізмів публічного управління системою охорони здоров‘я, виокремлено та охарактеризовано основні причини низької якості та ефективності надання медичних послуг громадянам, а саме: недостатня кількість спеціалістів; низький рівень кваліфікації медичного персоналу; недостатня кількість медичного обладнання та його моральна застарілість; низький рівень заробітних плат та відсутність дієвої системи стимулювання та мотивації. Існує, також, проблема невідповідності підготовки персоналу до потреб сучасної системи охорони здоров‘я; брак фінансових коштів та неможливість своєчасного надання медичної допомоги громадянам.

Published: September 2023

Pemeliharaan pembersihan permukaan luar fin-tube pada air-cooled heat exchanger dilakukan untuk menjaga performa agar tidak terganggu. Penurunan performa terjadi karena pengendapan zat pengotor berupa debu di permukaan luar fin-tube. Debu terakumulasi di atas sirip dan di antara sirip, debu terkumpul dalam bentuk bubuk halus dan bila terkena air dapat membentuk endapan berkerak. Pemeliharaan pembersihan masih dilakukan dengan menyeprotkan air melalui selang yang dilakukan sepenuhnya menggunakan tenaga manusia selama 80 jam untuk keseluruhan permukaan fin-tube. Untuk meningkatkan efektifitas pembersihan diperlukan inovasi perancangan sistem pembersihan dengan mengalirkan air melalui pipa dan nozel. Rancangan dilakukan secara manual menggunakan perhitungan berprinsip dasar hukum Bernoulli serta dilakukan simulasi menggunakan Ansys Fluent. Rancangan menghasilkan tekanan kerja yang cukup untuk menyuplai air dan kecepatan inlet nozel 0,37 m/s pada masing – masing nozel berjumlah 36 buah setiap fan atau 648 buah untuk mencakup 18 fan. Pembersihan dapat dilakukan dengan baik ketika kecepatan masuk nozel sebesar 0,37 m/s yang membutuhkan waktu pembersihan 59 menit dan mampu membersihkan debu sebanyak 2,40×10-8 kg dengan area pembersihan sebesar 0,75 m2 setiap nozelnya. Sistem pembersihan dioperasikan secara manual bertahap setiap bulan, jika diakumulasikan akan membutuhkan waktu 17,70 jam untuk membersihkan secara keseluruhan. Untuk mendapatkan hasil yang baik proses pembersihan hanya dapat berlangsung ketika fan tidak beroperasi.

Proses Melt Blending telah berhasil dikembangkan untuk membuat filamen 3DP dari bahan polimer. Percobaan dilakukan dengan mesin ekstrusi single screw kapasitas laboratorium. Modifikasi dilakukan dengan perancangan spider leg channel. Tools tersebut digunakan untuk mendapatkan campuran yang lebih homogen dalam fasa liquid di dalam ruang Extruder Head. Selain itu juga untuk mendapatkan tingkat kompresi selama pembentukan filamen di ruang nozzle. Percobaan dilakukan dengan mengunakan variasi filler pada komposit polimer karbon, yaitu komposit polimer karbon mikro dan komposit polimer grafit. Kedua variasi dibuat dengan komposisi berat yang sama 50:50. Untuk ukuran partikel karbon mikro digunakan mesh #200. Material polimer Linear Low Density Polyethylene/LLDPE digunakan sebagai matriks dengan ukuran mesh #40. Pada komposit polimer karbon mikro, diperoleh densitas yang relatif stabil pada temperatur setting untuk extruder head 110°C. Untuk komposit polimer grafit pembentukan filamen dengan kepadatan seragam belum berhasil diperoleh pada temperatur 110°C. Dalam kondisi kepadatan tersebut, konduktifitas listrik komposit dengan filler karbon mikro dan grafit menunjukkan fenomena perubahan yang mirip. Nilai konduktifitas listrik maksimal diperoleh pada area kanal spider leg dari extruder head. Karbon mikro sebagai filler lebih sensitif terhadap pemanasan dibandingkan dengan grafit, dan penggunaan mesin ekstrusi single screw hanya dapat dicapai dengan penambahan tools berupa extruder head.

Interprofessional education (IPE) in communities is often underrepresented in IPE initiatives, while, in practice, the need for collaboration is high enough. Interprofessional collaborative practice is challenging, especially for public health workers because some health professional education is unprofessional. Therefore, this brief review aims to comprehensively discuss the opportunities and challenges of public health students to perform interprofessional education. Study Review and data collection had been carried out within 2015-2020. Based on our review, IPE has a positive impact on students. Many students showed positive attitudes after participating in the Interprofessional Education session. Additionally, IPE is applicable for identifying benefits, challenges, and areas for modification when implementing and developing competencies. Managing interprofessional work team training is a major challenge. The approach to overcome these challenges can be realized by public health students by applying the basic skills and soft skills of public health workers, including a graphical model of public health. The model has four main tools, and particularly in the behavioral and social sciences, and health administration and policy will be a force to overcome the barriers to implementing IPE in the community. The results of the evaluation provide insight into the experiences of students, staff, facilitators, and their self-perception of competency development. Public health students perceive positively and believe that IPE can improve communication skills, collaboration, self-efficacy, readiness for interprofessional learning, and appreciation of professional roles. However, there is still a need for training modifications and expanding student roles that can improve understanding of primary health concepts and appreciation of interprofessional collaboration. This will increase students' potential to become effective healthcare providers.

In this context, the hospitality and catering industry attracts attention both with its new trends and the prospects of digital transformation in the future innovative development. Modern HoReCa business requires the implementation of various aspects of sustainability, innovation and new approaches in communication with consumers, as well as the implementation of new trends, which are caused by both the Covid-19 pandemic and the consequences of Russia's military aggression in Ukraine. For the business of the service industry, it is very important to know both yourself and your customers, and in the current period to be aware of the dynamics of the future market. In 2023, the hospitality industry is taking bold steps, including in Ukraine, where possible. The top trends show that business owners want and are finding innovative ways to improve the guest experience inside and outside the establishment. Businesses should develop strategies in this direction with the awareness of their strengths and weaknesses. In order to identify the strategies that will shape the service industry in 2023 and the following years, Internet research and forecasting by leading businessmen are carried out and analyzed. And even HoReCa enterprises are not in the first ranks of “the fourth great upheaval in production”, and the entire economy of Ukraine is now directed to military defense against the enemy, that time is not far when it will reach the same level with others in innovative development. In this context, this investigation is aimed at holistical assessment of trends and forecasts in the hospitality and catering industry, contribution to the literature and offering suggestions to relevant stakeholders.
