Interdependencies of Infrastructure Investment Decisions in Multi-Energy Systems—A Sensitivity Analysis for Urban Residential Areas
Authors: Then Daniel , Bauer Johannes , Kneiske Tanja M. , Braun Martin
Published: January 2021

Considering the European Union (EU) climate targets, the heating sector should be decarbonized by 80% to 95% up to 2050. Thus, the macro-trends forecast increasing energy efficiency and focus on the use of renewable gas or the electrification of heat generation. This has implications for the business models of urban electricity and in particular natural gas distribution network operators (DNOs): When the energy demand decreases, a disproportionately long grid is operated, which can cause a rise of grid charges and thus the gas price. This creates a situation in which a self-reinforcing feedback loop starts, which increases the risk of gas grid defection. We present a mixed integer linear optimization model to analyze the interdependencies between the electricity and gas DNOs’ and the building owners’ investment decisions during the transformation path. The results of the investigation in a real grid area are used to validate the simulation setup of a sensitivity analysis of 27 types of building collectives and five grid topologies, which provides a systematic insight into the interrelated system. Therefore, it is possible to identify building and grid configurations that increase the risk of a complete gas grid shutdown and those that should be operated as a flexibility option in a future renewable energy system.

Authors: Carminati Marco , Sinha Ganesh R. , Mohdiwale Samrudhi , Ullo Silvia L.
Published: January 2021

Sensors and electronics technologies are pivotal in several fields of science and engineering, especially in automation, industry and environment monitoring. Over the years, there have been continuous changes and advancements in design and miniaturization of sensors with the growth of their application areas. Challenges have arisen in the deployment, fabrication and calibration of modern sensors. Therefore, although the usage of sensors has greatly helped improving the quality of life, especially through their employment in many IoT (Internet of Things) applications, some threats and safety issues still remain unaddressed. In this paper, a brief review focusing on pervasive sensors used for health and indoor environment monitoring is given. Examples of technology advancements in air, water and radioactivity are discussed. This bird’s eye view suggests that solid-state pervasive sensors have become essential parts of all emerging applications related to monitoring of health and safety. Miniaturization, in combination with gamification approaches and machine learning techniques for processing large amounts of captured data, can successfully address and solve many issues of massive deployment. The development paradigm of Smart Cities should include both indoor and outdoor scenarios.
Induction Motor Multiclass Fault Diagnosis Based on Mean Impact Value and PSO-BPNN
Authors: Lee Chun-Yao , Ou Hong-Yi
Published: January 2021

This paper presents a feature selection model based on mean impact value (MIV) to solve induction motor (IM) fault diagnosis on the current signal. In this paper, particle swarm optimization (PSO) is combined with back propagation neural network (BPNN) to classify the current signal of IM. First, the purpose of this study is to establish IM fault diagnosis system. Additionally, this study proposes a feature selection process that is composed of MIV, whose objective is to reduce the number of classifier input features. Secondly, the features are extracted as a feature database after analyzing the current signal of IM, and the fault diagnosis is established through the model of PSO-BPNN. Finally, redundant features are deleted through this feature selection process and a classifier is built. The result shows that the feature selection model based on MIV can filter the features effectively at a signal to noise ratio of 30 dB and 20 dB for the IM fault detection problem. In addition, the computing time of BPNN is also reduced which is helpful for online detection.
The Interaction of Diabetes and Tuberculosis: Translating Research to Policy and Practice
Authors: van Crevel Reinout , Critchley Julia A.
Published: January 2021

Diabetes Mellitus increases the risk of developing Tuberculosis (TB) disease by about three times; it also doubles the risk of death during TB treatment and other poor TB treatment outcomes. Diabetes may increase the risk of latent infection with Mycobacterium tuberculosis (LTBI), but the magnitude of this effect is less clear. Whilst this syndemic has received considerable attention, most of the published research has focussed on screening for undiagnosed diabetes in TB patients or observational follow-up of TB treatment outcomes by diabetes status. There are thus substantial research and policy gaps, particularly with regard to prevention of TB disease in people with diabetes and management of patients with TB–diabetes, both during TB treatment and after successful completion of TB treatment, when they likely remain at high risk of TB recurrence, mortality from TB and cardiovascular disease. Potential strategies to prevent development of TB disease might include targeted vaccination programmes, screening for LTBI and preventive therapy among diabetes patients or, perhaps ideally, improved diabetes management and prevention. The cost-effectiveness of each of these, and in particular how each strategy might compare with targeted TB prevention among other population groups at higher risk of developing TB disease, is also unknown. Despite research gaps, clinicians urgently need practical management advice and more research evidence on the choice and dose of different anti-diabetes medication and effective medical therapies to reduce cardiovascular risks (statins, anti-hypertensives and aspirin). Substantial health system strengthening and integration may be needed to prevent these at risk patients being lost to care at the end of TB treatment.

The present article explores the relationship between the EEG rhythms' oscillations and the personality traits in a group of young males (soccer players and sport students). EEG was recorded by a single-channel wireless EEG system in the prefrontal cortex. Personality traits were identified in accordance with Eysenck's personality questionnaire. The regression model was used to analyse the EEG rhythms as possible predictors for Eysenck's personality traits. The findings of the study highlighted two slow rhythms that can be considered as predictors for personality traits, specifically: delta wave – for extraversion with negative slope, which could be related to mood, and theta wave – for neuroticism with negative slope, which could be related to inhibition. Those EEG patterns could condition preference for certain behavioural strategies in accordance with type of temperament. In addition, for two EEG high-frequency rhythms, association was revealed with personality traits: for beta rhythm as a hypothetical predictor for neuroticism, and for gamma rhythm – for lie. The statistically significant relationship between the slow bands with neuroticism and extraversion indicate to influences of the emotion-generating and reticular brain structures. In conclusion, the prefrontal cortex's background EEG activity can reflect preference of certain behavioural strategies, which are formed in accordance with individual type of temperament. This implies that study further examined probability association between the higher frequency bands (beta and gamma) and personality traits, which would be achieved in future researches. In addition, the data derived from a single-channel wireless system equipment demonstrated results, which is close to EEG recorded by conventional lab-based equipment.

Published: January 2021

To assess correlates of glycemic control in a multiethnic federally qualified health center population. Deidentifed data from a federally qualified health center were examined for patients in diabetes treatment. New variables were created to assess illness burden. Bivariate testing was done to assess treatment compliance by language group. Multinomial regression models assessed three outcomes: uncontrolled, controlled and well controlled glycated hemoglobin (Hba1c). The conceptual framework for this study was Andersen’s Health Care Utilization Model. The sample was 1,581 patients. The average was 56. Eighty Five percent of the patients had well controlled or controlled Hba1c. Mandarin speakers were the most likely to have Hba1c controlled despite having the highest average age. Immigrant English speakers had worse glycemic control then their monolingual counterparts. All Asian subgroups had better glycemic control than Hispanics and African Americans. In the final model, the correlates of glycemic control were illness burden, time spent with a provider and health promoting activities. English speaking Hispanics and African Americans continue to have worse glycemic control regardless of having access to care.

Is there a Similiarity between Fibonacci Sequence and Euler’s Number with Respect to Quantum Perspective Model?
Authors: Ölmez Tahir
Published: January 2021

According to Quantum Perspective Model, this article studies whether there is a link between the Euler’s numbers and the Fibonacci series. When the digits of the Euler’s number after the comma are converted from decimal(10) number base system to binary(2) number base system, it corresponds to the number in the Fibonacci series.(0,1,1,2,3,5,8,13,21,34,55...)[7].From this point of view, when the first hundred digits of the Euler’s numbers after the comma were calculated, the number "55" (ten times) in the Fibonacci series was found, in particular. Besides, the eleventh number in the Fibonacci series is also "55".In other words, the approximate unchanged numbers of the golden ratio numbers after the comma can be reached for the first time after dividing them from “55” to “34” (1,618). In sum, Euler’s numbers are not only attributed to the Fibonacci series in mathematics, but also attributed to the golden ratio in nature.

Published: January 2021

The automotive industry and research centers have intensified the search for innovative solutions in the field of material technologies and have recently accelerated their work on thermoplastic based composites in line with their requirements. Thermoform method is used for rapid forming of thermoplastics and composites. In this process, mold design and especially molding parameters are important for part quality. Thermoplastic composite sheets take the shape of their final form by spring back after they come out of the mold as in sheet metals. Therefore, springback is a parameter that should be taken into account in the manufacturing process and product design. In this study, preliminary research was carried out to design the forming process in thermoform mold. The experiments were done on Nakajima test setup and according to ISO 12004 standard. In the deep drawing of thermoplastic composite laminates, the effects of different holding pressure (0.4; 0.6; 0.8 MPa), punch speed (90, 120, 150 mm/min), specimen temperature (129, 159, 169 oC) and piece depth (20, 25, 30 mm) parameters on the molding force were examined and the spring back amount of deep drawn specimens was determined. As a result of the experiments, as the specimen temperature increased the molding force decreased. The molding force increased as the holding pressure increased. Increasing punch speed caused an increase in required molding force. As a result of the experiments, it was concluded that deep drawing can be made up to a depth of 25 mm.﻿﻿﻿

Penelitian ini dilakukan berdasarkan perkembangan pendidikan di Jawa Barat yang semakin berkembangnya sekolah-sekolah berstandar internasional sebagai implikasi dari globalisasi. Kurikulum yang dikembangkan di sekolah-sekolah tersebut lebih mementingkan aspek penguasaan bahasa asing (bahasa Inggris) dalam setiap proses pendidikan. Tujuan penelitian ini adalah (1) untuk mengetahui kendala yang ditemukan dalam proses pemerolehan bahasa ke dua (bahasa Indonesia) dan bahasa ke tiga (bahasa Inggris) melalui pembelajaran Sains SD pada kelas yang menggunakan bahasa pengantar bahasa Sunda dan bahasa Indonesia dengan kelas yang menggunakan bahasa Indonesia dan bahasa Inggris; dan (2) untuk mengetahui kemunculan penggunaan bahasa ibu dalam proses pembelajaran Sains. Subjek penelitian adalah siswa SD di Kabupaten Bandung, yaitu di Kecamatan Solokan Jeruk dan di SD Laboratorium UPI Kampus Cibiru. Teknik pengumpulan data melalui observasi terhadap proses pembelajaran yang hasilnya dideskripsikan secara kualitatif. Metode observasi dilakukan terhadap situasi natural yang terjadi dalam kelas. Hasil penelitian menunjukkan bahwa siswa di Kecamatan Solokan Jeruk masih dominan menggunakan bahasa Sunda dalam proses belajar. Guru berusaha untuk menyesuaikan bahasa pengantar dengan kemampuan siswa. Guru berusaha pula untuk membimbing siswa memahami materi pelajaran menggunakan bahasa Indonesia. Hasil penelitian di SD Laboratorium UPI Kampus Cibiru menunjukkan bahwa kemampuan berbahasa Inggris siswa SD laboratorium UPI Kampus Cibiru sudah cukup baik. Siswa mengenal berbagai kosakata bahasa Inggris tentang hal-hal yang berhubungan dengan alam. Akan tetapi, proses pembelajaran terlihat sama sekali tidak memunculkan penggunaan bahasa Sunda sebagai bahasa pengantar. Saran yang diajukan adalah bahwa sebaiknya proses pembelajaran Sains tidak mengesampingkan pemertahanan kelestarian bahasa Sunda. Bahasa Sunda dapat diaplikasikan pada pembelajaran Sains terpadu secara tribahasa beriringan dengan bahasa Indonesia dan bahasa Inggris. Hal ini diharapkan juga dapat meningkatkan keterampilan berbahasa siswa secara lebih komprehensif yang disesuaikan dengan tingkat perkembangan bahasa siswa.

This article presents the results of studying the dimensional accuracy of the bases of complete removable prostheses made using a 3D printer and the traditional method. Bases of complete removable prostheses were made using an intraoral laser scanner iTero Cadent (USA) and a 3D printer Asiga Max UV (Australia). To study the dimensional accuracy of the bases of complete removable prostheses, we used the DentalCAD 2.2 Valletta software. The Nonparametric Wilcoxon W-test was used for statistical analysis of the obtained data. We found that the average value of the difference with the standard for bases made using digital technologies is 0.08744±0.0484 mm. The average value of the difference with the standard for bases made by the traditional method is 0.5654±0.1611 mm. Based on these data, we concluded that the bases of complete removable prostheses made using modern digital technologies (intraoral laser scanning and 3D printer) have a higher dimensional accuracy compared to the bases of complete removable prostheses made using the traditional method with a significance level of p<0.05 (Wilcoxon's W-test=0, p=0.031). Keywords: digital technologies in dentistry, digital impressions, intraoral scanner, 3D printing, ExoCAD, complete removable dentures.

MONOFINITE COMPLEX CLAUSE IN THE KUMYK LANGUAGE
Authors: Abdullabekova U. B.
Published: January 2021

This article aims to analyze the monofinite complex clause in the Kumyk language in terms of structure. The originality of the research lies in the fact that the article proposes a different approach than in Russian studies on the analysis of the syntactic structure of a sentence. The relevance of the research is determined by the role of the sentence structure and methods of its study in linguistics in general. The main method used in the study is the method of syntactic modeling, which is used in terms of functions (members of a sentence), in terms of morphological forms of words and the semantic structure of a sentence.

Turkic languages are not characterized by properly complex sentences with two formally independent finite parts connected by an analytical form. Case affixes and postpositions form not finite verb forms, but infinite verb forms. Such constructions in agglutinative languages are central and most frequent. The monofinite complex clause, or a sentence complicated by an infinite phrase (participial and adverbial phrase), or “polypredicative construction” according to the Novosibirsk syntactic school is investigated in this article.

The author argues that when characterizing a complex clause, it is necessary to take into account such parameters as the finiteness / infiniteness of the dependent predicate, the nature of the means of communication and the referential identity / non-identity of the subjects of the main and dependent parts.

The constructive center of a monofinite complex clause is the indicator of connection –analytical, that is, an auxiliary word, or synthetic, that is, a morpheme in the composition of a dependent predicate. Formally, this is a part of the infinite form of such a predicate, but functionally it serves to express the relationship between the predicative parts. Since the dependent predicate in the Kumyk language occupies the final position in the dependent predicative unit, the synthetic link indicator is located on the border between the main predicative unit and the dependent predicative unit.
TRANSFORMATION OF A FAIRY TALE IN «HYBRID» SCIENCE FICTION (BASED ON AMERICAN AND RUSSIAN PROSE OF THE XXth CENTURY)
Authors: Malykh V. S.
Published: January 2021

The article introduces and substantiates the concept of «hybrid» science fiction, which combines the elements of science fiction and horror fiction. In «hybrid» fiction, science fiction surroundings cannot rationalize the text, but, on the contrary, they are replaced by motives of supernatural horror. «Hybrid» science fiction, in contrast to «hard» science fiction , develops the idea of ​​ unknowability of the Universe. It is worth mentioning here, that «hard» science fiction has been described well enough, but there is a shortage of research work in relation to its «hybrid» version, so this research can be considered as pioneering.

We use E. M. Neyolov’s typology that describes the connection between a fairy tale and «hard» science fiction. Basing on this typology, we analyse «hybrid» fiction, in which science fiction scenery was replaced by the anti-rational principle. The research methodology involves a combination of structural, typological and comparative methods. As a material for the study, we use the works of such Russian and American authors as D. Glukhovsky, S. Lukyanenko, G. R. R. Martin, S. King, C. McCarthy, H. P. Lovecraft and others. The purpose of the article is to identify and describe the transformation of fairytale discourse in the works of these authors that leads to the genre transition from science fiction to horror fiction. The texts are being analysed from three points of view: system of characters, the structure of space and the direction of time.

It is concluded that in «hybrid» science fiction the typological model of the fairy tale was distorted, reconsidered or destroyed, and it is the aberration of the fairytale motif that opens the gate for the genre transformation from «hard» science fiction to horror fiction. For example, the struggle of the superhero with the supervillain is traditional both for fairy tales and for science fiction, but it is replaced by psychologization of the hero and the extreme complication of the metaphysics of the Good and the Evil in «hybrid» science fiction . Besides that, the well-organized space of fairytale and science fiction as well as a close-cut separation of «ours» and «aliens», and also the mythologem of «threshold» are mixed in «hybrid» fiction and lose their symbolical unambiguity. Finally, science fiction and fairytale time in «hybrid» fiction ceases to exist and gives way to the tragic timelessness of chaos and nightmare.

Thus, «hybrid» fiction destroys both the canons of «hard» science fiction and the constructs of the fairy tale genre.

In this work, we investigated the influence of the Mg/Sn supply ratio into Mg2Sn thin film, deposited on Al2O3(0001) (sapphire c-plane) substrate using molecular beam epitaxy (MBE), as well as the effect of incorporating Ge. We demonstrated that a low ratio of Sn to Mg improved the thin film’s quality, while the incorporation of Ge atoms (into the Sn sites) resulted in superior thermoelectrical properties (p-type). Our results suggest that the improvement of the thermoelectric properties could be associated with point defects in the Mg site. The optimal power factor value obtained was 2.7 × 10−4 W ∙ m−1 ∙ K−1 at 300 K for the Mg2Sn0.8Ge0.2.
Non-thermal liquid-to-solid Si conversion induced by electron beam irradiation
Authors: Mori Masahiro , Akabori Masashi , Tomitori Masahiko , Masuda Takashi
Published: January 2021

A liquid precursor for the semiconductor, Si, called liquid Si (liq-Si), was synthesized. Although liq-Si is converted to semiconducting Si by heating at 400 °C, herein, we demonstrate liquid-to-solid Si conversion without heating using liquid-phase electron beam-induced deposition. This technique realizes the direct deposition of semiconducting Si by irradiating liq-Si with an electron beam. Specifically, at electron beam (diameter, ∼50 nm) irradiation, a Si deposit with a diameter of approximately 240 nm was obtained. It is expected that the application of this developed method will enable the production of high-resolution Si nanostructures and grant access to previously inaccessible devices.
Influence of light illumination on the potential-induced degradation of n-type interdigitated back-contact crystalline Si photovoltaic modules
Authors: Xu Yuansong , Masuda Atsushi , Ohdaira Keisuke
Published: January 2021

We investigate the potential-induced degradation (PID) of n-type interdigitated back-contact (IBC) crystalline Si (c-Si) photovoltaic (PV) modules under a negative bias stress and the influence of light illumination on the PID. IBC PV modules show PID characterized by a reduction in the short-circuit current density (J
sc) and open-circuit voltage (V
oc) under negative bias stress, while no fill factor (FF) reduction is observed. The degradation may originate from the introduction of sodium (Na) into c-Si and the resulting enhancement of carrier recombination on the surfaces of the IBC cells. Light illumination of 1 sun during the negative bias PID test results in less severe reductions of J
sc and V
oc. A reduction in the electric field on the surface Si nitride (SiN
x
) film, due to carrier generation in the SiN
x
and the resulting increase in its conductivity, is a possible explanation for the mitigation of the Na-related PID.
Effects of water and hydrogen introduction during In–Ga–Zn–O sputtering on the performance of low-temperature processed thin-film transistors
Authors: Magari Yusaku , Furura Mamoru
Published: January 2021

In–Ga–Zn–O (IGZO) films were deposited by sputtering in Ar + O2 + H2 and Ar + H2O atmosphere to investigate the effects of H2 and H2O introduction on physical and electrical properties of IGZO films and thin-film transistors (TFTs). A substantial reduction and oxidation of the IGZO films were confirmed by introducing H2 and H2O, respectively. We found that electron traps were formed for the Ar + H2O-sputtered IGZO TFTs, resulting in a degradation of field-effect mobility (μ
FE), subthreshold swing (S.S.), and hysteresis (V
H). In contrast, such degradations were not observed in the Ar + O2 + H2-sputtered IGZO TFTs and it exhibited μ
FE of 12.5 cm2 V−1 s−1, S.S. of 0.15 V dec−1, and V
H of 0.5 V. Hard X-ray photoelectron spectroscopy analysis revealed that excess oxygen incorporated during Ar + H2O sputtering is a possible cause of the TFT degradation. Thus, the reduction process, namely, Ar + O2 + H2 sputtering, is a promising approach for low-temperature-processed (∼150 °C) oxide TFTs for future flexible device applications.
Controlling filament growth mode in resistive random-access memory based on thermal flow
Authors: Sasaki Yuta , Kinoshita Kentaro
Published: January 2021

To use resistive random-access memory (ReRAM) in various attractive applications, the guidelines of the device structure are required for controlling memory characteristics. In this study, 3D simulation of oxygen vacancy (VO) diffusion was performed by adopting a combination of Soret and Fick diffusions as driving forces of VOs in NiO layers of Me/NiO/Me devices (Me = Pt, Ru, W). It was demonstrated that the reciprocating motion of VOs, accompanying resistive switching, could be reproduced consistently with good cycling endurance for unipolar-type ReRAM. Furthermore, our simulation revealed that the thermal flow from the NiO layer to the electrode (EL) caused VO migration in the vertical direction, and affected both SET and RESET switching in contrast to previous reports. Accordingly, it is clear that the three-dimensional thermal design of the device structure considering ELs is crucial for tuning memory characteristics by controlling the balance of Fick and Soret diffusions.
Modulation of intertube band dispersion relation of carbon nanotube bundles by symmetry and intertube wave function coupling
Authors: Okada Susumu , Gao Yanlin , Maruyama Mina
Published: January 2021

Based on density functional theory with a local density approximation and the simple tight-binding approximation, we investigated an electronic structure of carbon nanotube bundles in terms of mutual nanotube arrangement. The dispersion relation near the Fermi level along the intertube direction was found to be sensitive to the nanotube species and their mutual orientation within the bundles. Nanotube bundles with three-fold symmetry exhibited a substantial orientation dependence in the band dispersion relation along the intertube direction. The tight-binding calculation and wave function analysis revealed that this orientation dependence arises from the intertube wave function coupling whether a node exists between nanotubes.

Published: January 2021

The advent of the retail point of sale (POS) system as a critical component of the traditional retail infrastructure seeks to advance client payment-ease for goods and services rendered by vendors as well as the effective collection of funds by the vendor. It also aids the vendor to collect in advance monies that the client may wish to spend later on goods and services.

COMPATIBILITY PROBLEM OF BASIC PUBLIC VALUES WITH ECONOMIC POLICY GOALS AND DECISIONS FOR THEIR IMPLEMENTATION
Authors: GVELESIANI REVAZ
Published: January 2021

Economic policy related decisions are very complex in their logical structure because of the multilateral interdependence of the Social-economic events. Every decision includes some kind of vagueness. It is either clear or vague whether economic-political situation and results of discussed actions are analyzed well. The logical structure of decisions is the objective of the theory of the decision making. This theory helps to assess and overcome the problems in economic policy related decision making. Economic policy is oriented on achieving the predefined goals. These goals are determined by economic situation and many normative attitudes (basic values). There is an agreement on one part of the goals among the majority of developed countries. The laws and resolutions issued by different governments often include economic indicators, including: significant economic growth, high level of employment, appreciating the currency as an indicator of stability of prices, foreign economic relations, foreign economic equilibrium or fair distribution of the income and the property. This is the partial list of the goals, but it is enough to demonstrate that goals are the only means (instruments) for realizing all-inclusive norms of basic public values.

Authors: KURSAD OZEKIN MUHAMMED
Published: January 2021

The nexus between globalization and international development is one of the most debatable issues in today’s development literature. Broadly, there are two camps: the
diffusionist accounts of neoliberal school of thought or what we might call optimists and the so-called radical school of thought or pessimists. Rather than taking sides with either
of these two camps, this study embraces a middle ground approach to the matter of globalization and development. Overall, it argues that globalization causes complex patterns of convergence and divergence across regions and between countries that its impacts cannot be observed at the same degree and effect in all ages and economies of the world. In the light of this argument, this study aims to explore the impact of globalization on the unevenness of international
Attribute-Based Encryption for Access Control in Cloud Ecosystems
Authors: bartolomeo giovanni
Published: January 2021

We introduce a distributed, fine-granuled,
policy-based resource access control protocol leveraging on Attribute-Based
Encryption. The protocol secures the whole access control procedure from the
authorization issuer to the resource server providing grant confidentiality,
proof of possession, antiforgery and may be implemented through a developer
familiar web token exchange flow plus a HTTP basic authentication flow. As
such, it may map to Cloud computing SaaS paradigm, enabling microservices
integration into a single, authorization-centric digital ecosystem, even across
multiple identity domains. We also present the results of a performance
evaluation on a first prototype implementation.
