A Physics-based Virtual Reality System Design and Evaluation by Simulating Human-Robot Collaboration
Authors: Chowdhury Suman , Mubarrat Syed T. , Fernandes Antonio
Published: January 2022

Recent advancements in VR technology facilitate
tracking real-world objects and users' movements in the virtual environment
(VE) and inspire researchers to develop a physics-based haptic system (i.e.,
real object haptics) instead of computer-generated haptic feedback. However,
there is limited research on the efficacy of such VR systems in enhancing
operators’ sensorimotor learning for tasks that require high motor and physical
demands. Therefore, this study aimed to design and evaluate the efficacy of a
physics-based virtual reality (VR) system that provides users realistic
cutaneous and kinesthetic haptic feedback. We designed a physics-based VR
system, named PhyVirtual, and simulated human-robot collaborative (HRC)
sequential pick-and-place lifting tasks in the VE. Participants performed the
same tasks in the real environment (RE) with human-human collaboration instead
of human-robot collaboration. We used a custom-designed questionnaire, the
NASA-TLX, and electromyography activities from biceps, middle and anterior
deltoid muscles to determine user experience, workload, and neuromuscular
dynamics, respectively. Overall, the majority of responses (>65%)
demonstrated that the system is easy-to-use, easy-to-learn, and effective in
improving motor skill performance. While compared to tasks performed in the RE,
the PhyVirtual system placed significantly lower physical demand (124.90%; p
< 0.05) on the user. The electromyography data exhibited similar trends (p
> 0.05; r > 0.89) for both environments. These results show that the
PhyVirtual system is an effective tool to simulate safe human-robot
collaboration commonly seen in many modern warehousing settings. Moreover, it can
be used as a viable replacement for live sensorimotor training in a wide range
of fields.

Published: January 2022

Non-orthogonal multiple access (NOMA) is a better multiple access technique than orthogonal multiple access (OMA), precisely orthogonal frequency division multiple access (OFDMA) scheme, at the conceptual level for fifth-generation (5G) networks and beyond 5G (B5G) networks. We investigate the potentials of the schemes by comparing the proposed NOMA scheme with the traditional cooperative communication NOMA (CCNOMA) scheme, rather than the comparison between NOMA and OMA only. To probe the effectiveness of NOMA as a multiple access technique, we propose a novel NOMA scheme considering two adjacent BSs with a special design of the transceiver architecture. The proposed scheme provides a reasonable data rate to both near user (NU) and far user (FU) without compromising the quality of service (QoS) to anyone of them. The conclusive analyses on the optimization framework of multi-user sum rate, capacity, transmit power, spectral efficiency (SE), and energy efficiency (EE) trade-off for NOMA and OFDMA schemes have been established to a succession of derivations. Under the analytical optimization framework, we also prove quite a few properties for them. Simulation results confirm the theoretical findings and show that the two schemes can efficiently approach the optimal power allocation, minimization of power consumption, and optimal SE-EE trade-off, and the proposed NOMA scheme provides comparatively better data sum rates than the baseline OMA scheme.
Coupled Alternating Neural Networks for Solving Multi-Population High-Dimensional Mean-Field Games with Stochasticity
Authors: Wang Guofang , Yao Wang , Zhang Xiao , Niu Zijia
Published: January 2022

Multi-population mean-field game is a critical subclass of mean-field games (MFGs). It is a theoretically feasible multi-agent model for simulating and analyzing the game between multiple heterogeneous populations of interacting massive agents. Due to the factors of game complexity, dimensionality disaster and disturbances should be taken into account simultaneously, how to solve the multi-population high-dimensional stochastic MFG problem is faced with great challenges. We present CA-Net, a coupled alternating neural network approach for tractably solving multi-population high-dimensional MFGs in the stochastic case. First, we provide a universal modeling framework for large-scale heterogeneous multi-agent game systems, which is strictly expressed as a multi-population MFG problem. Next, we generalize the potential variational primal-dual structure that MFGs exhibit, then phrase the multi-population MFG problem as a convex-concave saddle-point problem. Last but not least, we design a generative adversarial network (GAN) with multiple generators and multiple discriminators—the solving network, which parameterizes the value functions and the density functions of multiple populations by two sets of neural networks, respectively. Moreover, numerical experiments demonstrate the feasibility and effectiveness of our approach.

Ripensare i lastscapes. Da spazi altri a spazi pubblici: ipertopie al di là dei recinti
Authors: Vannelli Giovangiuseppe , D'Agostino Angela , Occhiuto Rita
Published: January 2022

Conventional description, interpretation and design processes for public space enter into crisis in the geography of the 20th-century sprawling city denoted by enclosures. In this complex geography, often coinciding with that of drosscape, heterotopias of deviation raise thorny issues in the contemporary urban landscape. Role and shape of these now obsolete heritages must be rethought starting with the enclosure walls, a representative element of the heterotopical identity of these places.This paper explores burial landscapes, lastscapes, as a chance for urban fragments surrounding them. These places should be interpreted as hypertopias and no longer as heterotopias, rather than “other spaces” they should be considered as public spaces. With this purpose, three design strategies are proposed, using northern European case studies: a project of rooms, a project of margins, a project of layers.

Intangibile, Emergente, Esplicito. Il progetto di paesaggio per la transizione ecologica
Authors: Marinaro Ludovica
Published: January 2022

The result of the ecological transition process today is nothing more than an intangible landscape. Still utopian, it is thought of as the custodian of our desires, the communitarian expression of a democratic technology, a flexible dimension that will finally welcome a reformed society. As still potential and strictly dependent on our present action, the intangible landscape of ecological transition also has its Yang: the landscape of global warming of 2° C, in the scenario hypothesized by the latest report of the Intergovernmental Panel on Climate Change (IPCC). In balance between catharsis and catastrophe there is now a need for effective strategies to make the objective of transition concrete and the landscape, more than a mere destination, can today be understood as the main actor on the urban scene. Having cleared the field of misunderstandings and mystifications, the essay explores the potential of the landscape project as a political project of a solidary as well as ecological transition.

Authors: Bastos Francisco Glauco Gomes
Published: January 2022

“Afirmar que Rosalvo Florentino de Souza é um intelectual a serviço da educação pode parecer estranho, uma vez que, mesmo tendo escrito por duas décadas no jornal A Gazeta, de 1949 a 1968, de acordo com a coleção de recortes que se encontravam no Instituto de Estudos Educacionais “Sud Mennucci”, sobre temas relacionados à educação, mesmo tendo participado como membro e como fundador de diversas entidades de classe ligadas à educação, mesmo tendo sido professor secundário, não se encontra na literatura sobre História da Educação, seja do Brasil, seja do Estado de São Paulo, qualquer referência a ele. Foi a partir de um levantamento feito por uma aluna de graduação sobre certos recortes de jornais deixados por ele no Instituto de Estudos Educacionais “Sud Mennucci”, que, por intermédio da professora e pesquisadora Rosa Fátima de Souza Chaloba, tomei conhecimento do legado deixado por esse baiano nascido em Caetité”. Há neste livro-tese trabalho árduo, pesquisa séria e devoção à educação e ao ensino. O professor Glauco Bastos traz, através de uma imersão em documentos gastos pelo tempo, um olhar do intelectual - Rosalvo Florentino de Souza – sobre a cultura escolar dos idos anos de 1940 a 1960. Esta obra ratifica a relevância da pesquisa documental para que se compreenda a História da Educação Brasileira e, mais ainda, para que se preencham lacunas inestimáveis de políticas públicas de ensino em São Paulo à época estudada. Por meio de um trabalho a Sherlock Holmes, Glauco Bastos se apropria brilhantemente de matérias escritas pelo articulista Rosalvo Florentino no jornal “A Gazeta” para nos presentear com uma peça extraordinária para o entendimento dos muitos caminhos percorridos pelo magistério nacional até os dias atuais. Enfim, a academia e o público em geral têm neste livro fonte de pesquisa ímpar e certeza de uma leitura profícua e agradável.

Стаття присвячена аналізу характерних рис, проблем та перспектив залучення і використання іноземних інвестицій в економіці України передусім з огляду на важливість забезпечення їх позитивного впливу на експортну діяльність вітчизняних суб’єктів господарювання. Наведено особливості функціонування міжнародного інвестиційного ринку в умовах глобалізації у сфері фінансів. Окреслено роль транснаціональних компаній на сучасному етапі розвитку системи міжнародних фінансів. Наголошено, що прямі іноземні інвестиції для нашої країни виступають однією з найбільш бажаних форм довгострокових капіталовкладень, тому що вони сприяють реалізації потужних амбітних та великих проектів виробничого, технологічного, маркетингового призначення, що сукупно визначає експортні можливості країни на світових ринках. Проведено аналіз динаміки, географічної та галузевої структури прямих іноземних інвестицій в Україні. З’ясовано, що: найбільші іноземні інвестори в нашій країні є представниками невеликої кількості країн; у іноземному капіталі чітко простежується група офшорного інвестування; у галузевій структурі інвестицій домінують сфери, орієнтовані на швидку окупність та низьку технологічність. Розглянуто основні проблеми у розвитку експортної діяльності та визначено сучасні чинники, що визначили процеси експортної діяльності України у 2020 році. Побудована економетрична модель залежності показника експорту товарів та послуг України від надходження прямих іноземних інвестицій на основі сучасних статистичних даних за 2004-2020 рр. У результаті дослідження встановлено, що вплив прямих іноземних інвестицій на розвиток експортного потенціалу України в економіці нашої країни вже почав проявлятися. Водночас наголошено про необхідність подальшого залучення іноземних інвестицій в економіку України, що обумовлено пріоритетністю структурної перебудови вітчизняного промислового комплексу, нарощування експортного потенціалу країни, реалізацією стратегій подолання залежності економіки від імпорту енергоресурсів тощо.

Published: January 2022

У статті досліджуються передумови застосування та впровадження міжнародного досвіду управління персоналом на підприємствах України. Метою написання статті є підтвердження необхідності у застосуванні міжнародного досвіду управління персоналом на українських підприємствах. Оцінювання країн та їх успіху в обраній тематиці здійснювалося згідно з індивідуальними економічними показниками, а також розглянуто системи управління країн та вибрано найбільш оптимальні для українських підприємств. Визначено сутність понять “управління” та “персонал”. При написанні статті використовувалися різного виду методи, такі як: порівняння для того, щоб виявити та надати оцінку різновиду рис, які будуть здатні адаптуватися до конкретних економічних умов; експертні оцінки для виявлення особливостей менеджменту та його методів, які використовуються іноземними країнами, щоб якісно сформувати власні методи управління на українських підприємствах. Дослідження доводять, що доцільним є використання досвіду систем управління на американських підприємствах, що розглядають працівника як індивідуальність і створюють безліч програм для самовдосконалення, та на японських, які багато вкладають у соціальну сферу та особливі підходи до кожного з працівників. Узагальнено, що адаптацію впровадження одержаних знань краще здійснювати зі сторони особистої орієнтації системи управління персоналом, створення курсів всередині підприємств для постійного навчання та вдосконалення працівників, щоб обмінюватися досвідом із колегами та отримувати віддачу у вигляді позитивних результатів власної діяльності. Доцільне формування корпоративної культури підприємств, яка має створити особливі відносини між персоналом та керівництвом, та створення платформи сприятливого клімату для становлення бізнесу.

The antibacterial activity of the methanol leaf extract of A. paniculata against bacterial consortia from blood of diabetic patients was evaluated in this study.
Methods: The enumeration of bacteria from blood samples of diabetic patients and their antibiotic sensitivity pattern were done using standard techniques. The phytochemical analysis of A. paniculata methanol extract and antibacterial assay of the extract were also done using standard methods.
Results: Staphylococcus aureus had the highest occurring rate of 19.56 % while Klebsiella pneumoniae had the lowest occurring rate of 0.40 %. The isolates exhibited different sensitivity patterns to conventional antibiotics. There were variations in the zones of inhibition of A. paniculata methanol extract against the bacterial isolates as extract showed concentration was dependent on antibacterial activity with all the bacterial isolates susceptible to the extract. The minimum inhibitory concentration (mg/ml) of the A. paniculata methanol extract ranged from 5 mg/ml to 10 mg/ml while the minimum bactericidal concentration (mg/ml) of the bacteria isolated from diabetic patients ranged from 10 mg/ml to 20 mg/ml.
Conclusion: Findings revealed that the methanol leaf extract of A. paniculata very strong antibacterial activity for a wide range of bacteria from blood samples of diabetic patients and more reliable than commercially available antibiotics hence suggesting that leaves of A. paniculata can be used to develop novel antibacterial drugs.

Among vegetable plants grown indoors, cucumber is one of the main ones. In the structure of production, the area allotted for it is 60-70%. This is due to the fact that it provides a high yield compared to other vegetable plants, is capable of producing fruits for fresh consumption in low light conditions already 8-9 weeks after germination, which contributes to the provision of fresh fruits to the population in the winter-spring period. vegetable products, when its lack in people's
nutrition is especially acute. In addition, its fruits are easily absorbed by the body, as a result of which they are widely used in cooking as a dietary food. Favorable climatic conditions of closed ground, namely high temperature and humidity, favor the development of phytophages. This article confirms the feasibility and effectiveness of protecting greenhouse cucumber plants from pests. The highest yield - 36.5 kg / m2 was observed in the variant with the use of the drug Confidor 200 SL, r.c., which is 6 kg / m2 higher than in the control.In the variant with the use of the drug Actellik 500 EC, c.e. - 35.5 kg / m2, and using the biological preparation Aktofit, c.e. - 34.8 kg / m2, which is respectively 19.7 and 18.1% higher than in the control, where the average yield during the study period was 30.5 kg / m2. Based on the generalization of the obtained research results in specific production conditions, to obtain high yields and control the number of cucumber pests such as spider mites, greenhouse whiteflies and aphids in a greenhouse, it is recommended to use Aktofit preparations, c.e. at the rate of 2.0 l/ha, or Confidor 200 SL, r.k. - 0.25 l/ha, which will provide crop protection and a level of profitability at the level of 43.3-42.7%.

Published: January 2022

The highest and most stable grain yields of winter barley depend on the possibility of using the variety of soil and climatic conditions of cultivation at the maximum level, as well as the ability to overcome adverse meteorological factors that impair plant growth and development. Therefore, new varieties must be characterized by a complex system of biochemical, physiological and economically valuable traits and properties that ensure adaptability to specific growing conditions.
In recent years, climate change has become apparent in the central forest-steppe of Ukraine. Autumn and spring periods are often accompanied by drought, air storms. Precipitation is uneven, which is typical for the zone of unstable moistu. Winter barley can give high grain yields only on fertile soils and for the application of a sufficient amount of fertilizers. Therefore, in modern intensive technologies, the use of mineral fertilizers has an important place. It is especially important to carry out nitrogen fertilization of crops, which should be moderate in autumn and during tillering and the formation of elements of the yield structure. Plants assimilate nitrogen most intensively during the period of active growth - from the spring tillering phase to the heading phase. Introduction of diammofosk N10P26K26 + N34 for top dressing in the phase of the beginning of tillering + N46 the beginning of the emergence of plants into the tube under pre-sowing cultivation for growing winter barley winter barley plants and foliar feeding with urea at a dose of N8 + microfertilizer Ecolist at a rate of 4,0 l/ha contributed to the opportunity to obtain grain yield of winter barley varieties Atlant Mironovsky at the level of 6,81 t/ha, Paso variety – 7,29 t/ha, which is more for the control plots without fertilization, by 4,97-5,23 t/ha.

Published: January 2022

Nanocomposites of poly(lactic acid) with sepiolite needles (5 wt.%) were evaluated in terms of the mechanical and biofilm formation properties. The nanocomposite exhibited higher values of the Young�s modulus and tensile strength at break compared to the PLA, without detriment in the percent elongation at break. These improvements were related to the high aspect ratio of the nanoclay, the polymer-clay interactions, and the degree of dispersion. The growth of Pseudomonas aeruginosa on the surface of the PLA and nPLA materials was promoted in different conditions. Medium with different concentration of nutrients were used and also were compared the effect of the medium physical state (solid or liquid medium). Biofilms were formed in all the conditions. However, the nanocomposite presented a higher area coverage of microorganisms on its surface, possibly due to the positive effects of the nanoclay on the bacterial adhesion.

Published: January 2022

Closed-form model for the delay estimation of current-mode Resistance Inductance Capacitance (RLC) interconnects in VLSI circuits is presented. The existing Eudes model for interconnect transfer function approximation is extended and applied for further accurate estimation of delay. With the equivalent lossy interconnect transfer function, finite ramp responses are obtained and line delay is estimated for various line lengths, per unit length inductances and load capacitances. The estimated delay values of extended Eudes model are compared with the existing Eudes model against HSPICE W-element model. The obtained delay values of Eudes model worst-case error percentage is 14.3% whereas our extended Eudes model is in good agreement with those of HSPICE results within 2% for the line lengths of 1mm to 10mm.

PENCIPTAAN BUSANA HAUTE COUTURE DENGAN KONSEP BURUNG JALAK BALI
Authors: Leliana Sari Dewa Ayu Putu
Published: January 2022

Tulisan ini merupakan hasil luaran dari diseminasi p2s (penelitian dan penciptaan seni) pada tahun 2018 yang didanai oleh DIPA ISI Denpasar yang bertujuan untuk menciptakan  Busana Haute couture dengan konsep Jalak Bali berbahan endek tradisional Bali sehingga dapat melestarikan budaya yang ada.  Burung jalak Bali merupakan burung asli/endemic yang dimiliki oleh pulau Bali yang keberadaanya terancam punah. Ciri khas yang dimiliki jalak Bali yaitu berupa kicauannya yang indah, serta fisik/penampilannya yang memukau. Ciri khususnya yaitu memiliki bulu yang putih di seluruh tubuhnya kecuali pada ujung ekor dan sayapnya yang berwarna hitam, serta pada bagian pipi yang tidak ditumbuhi bulu dengan warna biru cerah, mempunyai jambul yang indah. Keindahan Jalak Bali menarik untuk di wujudkan dalam penciptaan adibusana atau lebih dikenal dengan haute couture, menciptakan  busana  haute  couture menjadi  salah  satu  pilihan  yang  terbaik,  karena  selain  dibuat  dengan  teknik  penjahitan  yang  rumit,  busana  ini  juga  diciptakan  khusus  untuk  kalangan  tertentu,  sehingga  produk  yang  dihasilkan  tidak  mungkin  pasaran,  bahkan  tidak mudah  ditiru dan biasanya hanya diciptakan satu potong dan tidak diperbanyak. Metode yang digunakan dalam penciptaan ini  menurut S.P Gustami (2007) yaitu tahap eksplorasi, perancangan dan perwujudan, namun sedikit diadaptasi berkaitan dengan proses desain fashion. Hasil penciptaannya berupa 5 buah busana haute couture yang terdiri dari 3 busana wanita dan 2 busana pria. Penggunaan kain endek dengan motif pepatran sebagai sumber inspirasi dalam penciptaan Busana haute couture sebagai upaya untuk melakukan pelestarian kain-kain tradisional Bali  yang dewasa ini tidak banyak diketahui oleh masyarakat dan banyak yang punah. Kain endek memliki ciri khas ragam hias dan penggunaannya yang sesuai dengan nilai-nilai sosial budaya setiap masyarakat.

Authors: Gerasimenko Valentina , Kurkova Dina , Simonov Kirill , Trotsenko Anastasiya
Published: January 2022

The article analyzes existing barriers for innovative entrepreneurship in Russian markets that raise obstacles to market efficiency. The purpose of the study is to rethink the role of the main barriers to creating competitive Russian startups, to identify the basic reasons for the failure of Russian new high-tech companies in the fields of information technology, biotechnology, medicine and pharmaceuticals, and to provide an insight in relative significance and sectoral characteristics of these factors. To identify the conditions and circumstances underlying unsuccessful start-up, the authors developed the methodology, conducted interviews with start-up participants, provided a comparative quantitative assessment and compiled the rating of existing barriers. All these made it possible to formulate the main reasons for Russian startups failures that relate primarily to product and market problems: difficulties in forming an adequate supply of in-demand goods and services, wrong choice of promotion strategy, limited marketing communications with a potential are associated with the lack of financial resources (inadequate financial planning, errors in investment design, underestimation of costs), alongside managerial and organizational issues (building cohesive professional teams and lack of leadership qualities among managers). The findings show that to minimize the risk of adverse outcomes, executives and employees of high-tech startups should pay special attention to target markets, marketing and strategic management. The unique approach of the research, together with the identification and classification of relevant barriers, contributes to understanding the specifics of high-tech startups in preventing their collapse.
