EEGG: An Analytic Brain-computer Interface Algorithm
Authors: Liu Gang , Wang Jing
Published: August 2021

Objective. Modeling the brain as a white box is vital
for investigating the brain. However, the physical properties of the human brain
are unclear. Therefore, BCI algorithms using EEG signals are generally a
data-driven approach and generate a black- or gray-box model. This paper
presents the first EEG-based BCI algorithm (EEGBCI using Gang neurons, EEGG)
decomposing the brain into some simple components with physical meaning and integrating
recognition and analysis of brain activity.

Approach. Independent and interactive components of
neurons or brain regions can fully describe the brain. This paper constructed a
relationship frame based on the independent and interactive compositions for
intention recognition and analysis using a novel dendrite module of Gang neurons.
A total of 4,906 EEG data of left- and right-hand motor imagery(MI) from 26
subjects were obtained from GigaDB. Firstly, this paper explored EEGG’s
classification performance by cross-subject accuracy. Secondly, this paper
transformed the trained EEGG model into a relation spectrum expressing
independent and interactive components of brain regions. Then, the relation
spectrum was verified using the known ERD/ERS phenomenon. Finally, this paper
explored the previously unreachable further BCIbased analysis of the brain.

Main results.
(1) EEGG was more robust than typical “CSP+” algorithms for the
poorquality data. (2) The relation spectrum showed the known ERD/ERS
phenomenon. (3) Interestingly, EEGG showed that interactive components between
brain regions suppressed ERD/ERS effects on classification. This means that
generating fine hand intention needs more centralized activation in the brain.

Significance.
EEGG decomposed the biological EEG-intention system of this paper into
the relation spectrum inheriting the Taylor series (in analogy with the data-driven but
human-readable Fourier transform and frequency spectrum), which offers a novel frame for analysis of
the brain.
Part 2: Spatially Dispersive Metasurfaces - IE-GSTC-SD Field Solver with Extended GSTCs
Authors: Smy Tom J. , Rahmeier Joao Guilherme Nizer Rahmeier , dugan jordan , Gupta Shulabh
Published: August 2021

An Integral Equation (IE) based field solver to compute the scattered fields from spatially dispersive metasurfaces is proposed and numerically confirmed using various examples involving physical unit cells. The work is a continuation of Part-

1 [1], which proposed the basic methodology of representing spatially dispersive metasurface structure in the spatial frequency domain, k. By representing the angular dependence of the surface susceptibilities in k as a ratio of two polynomials, the standard Generalized Sheet Transition Conditions (GSTCs) have been extended to include the spatial derivatives of both the difference and average fields around the metasurface. These extended boundary conditions are successfully integrated here into a standard IE-GSTC solver, which leads to the new IEGSTC-SD simulation framework presented here. The proposed IE-GSTC-SD platform is applied to various uniform metasurfaces, including a practical short conducting wire unit cell, as a representative practical example, for various cases of finite-sized flat and curvilinear surfaces. In all cases, computed field distributions are successfully validated, either against the semi-analytical Fourier decomposition method or the brute-force full-wave simulation of volumetric metasurfaces in the commercial Ansys FEM-HFSS simulator.
Practical Hybrid Beamforming for Millimeter Wave Massive MIMO Full Duplex with Limited Dynamic Range
Authors: Sheemar Chandan Kumar , Thomas Christo Kurisummoottil , Slock Dirk
Published: August 2021

Full-Duplex (FD) communication can revolutionize wireless communications as it doubles spectral efficiency and offers numerous other advantages over a half-duplex (HD) system. In this paper, we present a novel and practical joint hybrid beamforming (HYBF) and combining scheme for millimeter-wave (mmWave) massive MIMO FD system for weighted sum-rate (WSR) maximization with multi-antenna HD uplink and downlink users with non-ideal hardware.
Moreover, we present a novel interference and self-interference (SI) aware optimal power allocation scheme for the optimal beamforming directions. The analog processing stage is assumed to be quantized, and both the unit-modulus and unconstrained cases are considered.
Moreover, compared to the traditional sum-power constraints, the proposed algorithm is designed under the joint sum-power and the practical per-antenna power constraints. To model the non-ideal hardware of a hybrid FD transceiver, we extend the traditional limited dynamic range (LDR) noise model to mmWave. Our HYBF design relies on alternating optimization based on the minorization-maximization method.
We investigate the maximum achievable gain of a hybrid FD system with different levels of the LDR noise variance and with different numbers of radio-frequency (RF) chains over a HD system. Simulation results show that the mmWave massive MIMO FD systems can significantly outperform the fully digital HD systems with only a few RF chains if the LDR noise generated from the limited number of RF chains available is low. If the LDR noise variance dominates, FD communication with HYBF results to be disadvantageous than a HD system.
Influence of Thermal Post-deposition on Trap States in Sol-gel Indium Zinc Oxide TFTs
Authors: Chatterjee Neel , Weidling Adam M , Ruden P. Paul , Swisher Sarah
Published: August 2021

In solution-processed oxide thin-film transistors, post-deposition thermal processing significantly changes the film’s transport properties and is essential for high-performance devices. The mobility, bias stability and trapping-detrapping related hysteresis are improved with higher processing temperatures, which is generally attributed to decreased concentrations of localized states that act as electron traps. Fabricating and characterizing 29 devices, we provide further experimental evidence that post-deposition processing indeed leads to enhanced channel electron mobility in sol-gel indium zinc oxide TFTs, and, on the basis of a simple model, we extract physical parameters that yield a quantitative assessment of the changes in the densities and the properties of the localized trap states. The data is obtained for sol-gel indium zinc oxide thin films and TFTs subjected to thermal postdeposition processing from 300 to 500 0<\sup>C. The extracted parameters indicate that the trap state density in the bulk semiconductor and at the interface decrease by factors of 5 and 3, respectively. Furthermore, the localized states become shallower, and the band mobility increases with higher processing temperatures.

Position Paper: On Using Trusted Execution Environment to Secure COTS Devices for Accessing Industrial Control Systems
Authors: Ye Quanqi , Tan Heng Chuan , Mashima Daisuke , Chen Binbin , Kalbarczyk Zbigniew
Published: August 2021

Industrial Control Systems (ICS) are traditionally designed to operate in an "air-gapped" environment. With the advent of digital technologies, many ICS are adopting IT solutions to improve interoperability and operational efficiency. Thus, the air-gap assumption no longer holds in practice. Most ICS devices today are modernized with networking capabilities to facilitate system maintenance, upgrades, and troubleshooting. Since these devices are connected to the Internet, ICS networks face the same security threats as regular IT systems. In addition, ICS operators can connect commercial off-the-shelf (COTS) equipment to ICS networks to perform operational tasks. Those COTS devices are usually personal computers or even mobile devices, which can be infected with malware and become weapons against ICS. In this position paper, we examine the design challenges of establishing trust between COTS equipment and ICS. We also present some commonly used security solutions and discuss their deployment challenges due to issues caused by legacy systems. Finally, we introduce the Trusted Execution Environment (TEE), a technology commonly available on modern COTS devices, as a trust anchor for establishing secure communications with the ICS infrastructure. We discuss some research gaps related to the use of TEE and propose some recommendations to guide future research.

An Extreme Learning Machine-Based System Frequency Nadir Constraint Linearization Method
Authors: Liu Likai , Hu Zechun , Pathak Nikhil , Luo Haocheng
Published: August 2021

Large-scale
integration of converter-based renewable energy sources (RESs) into the power system will
lead to a higher risk of frequency nadir limit violation and even frequency
instability after the large power disturbance. Therefore, it is essential to
consider the frequency nadir constraint (FNC) in power system scheduling.
Nevertheless, the FNC is highly nonlinear and nonconvex. The state-of-the-art method to simplify the constraint is
to construct a low-order frequency response model at first, and then linearize the frequency
nadir equation. In this letter, an extreme
learning machine (ELM)-based network is built to derive the linear
formulation of FNC, where the two-step fitting process is integrated into one
training process and more details about the physical model of the generator are considered to reduce the fitting error.
Simulation results show the superiority
of the proposed method on the fitting accuracy.

FREQUENCY CHARACTERISTICS OF BENGALI AND TAMIL VOWELS IN VARYING SPEAKING RATE
Authors: Dr.Kala Samayan  , Elanthendral C  , Dr.Anamika Hui
Published: August 2021

Speech has its unique importance as the primary means by which language is expressed in all human cultures. It is a fluid phenomenon, characterized by rapid changes in articulation and its acoustic product. Vowels can differ in acoustic analysis in various aspects because the speech code varies with language, dialect, age and sex and specific physiological constraints of the speaker. Keeping in view that rate brings changes in speech and vowels being more acoustically approachable, it is assumed that there would be changes in vowel acoustics with change in rate of speech. The present study is aimed at understanding the influence of rate of speech on formant frequency of vowel acoustics in two different languages - Bengali (Indo-Aryan) and Tamil (Dravidian). The subjects for the study were grouped based on languages - Group I consisted of 10 males with native language as Bengali, Group II consisted of 10 males with native language as Tamil in the age range of 18 to 28 years. The results shows that the formant frequency of three similar vowels of /a/, /i/ and /u/ in both languages and non-similar/different vowel of /ɔ/ in Bengali and /Ʌ/ in Tamil indicates significant difference in varying speaking rate. The differences in vowel acoustics in varying speaking rate in Tamil and Bengali showed higher duration to read the passage in normal than fast rate.
KEYWORDS: Formant frequency, vowel acoustics, Tamil and Bengali

Published: August 2021

This article presents the ambitious potentialities in the use of digital methods and techniques for the documentation of the Nordic architectural heritage and environment.  The processes of knowledge, both theoretical and practical, should not ignore the traces of the past, old buildings and traditional constructions.  On the contrary, they should serve as a testimony of the past and provide a solid starting point for new, more coherent, sustainable and harmonic urban development.

Since the Venice Charter in 1965 up to the more recent international documents such as the Declaration of Amsterdam in 1975 and the Madrid Document in 2011, both the verification of authenticity and understanding of architectural entities and details are getting more insight because of the current technological advancements.  However, the methods for the analysis and following these noble principles and declaration articles is still not defined well enough.  Each method and practical procedure with specific instruments produce also specific outputs and results, which need to be put in mutual dialogue in order to obtain useful results.  These themes are studied and developed in this article by presenting chosen case studies in research projects both on the urban and singular scale with the location in Oulu, Finland.

Published: August 2021

Gefahrstofffreisetzungen aus technischen Anlagen können erhebliche Risiken für Mensch und Umwelt bergen und sind deshalb bei der Planung, der Genehmigung und im Regelbetrieb technischer Anlagen zu berücksichtigen. Zur Identifizierung von Gefahrenbereichen im Zusammenhang mit Gasfreisetzungen und zur Bewertung der Wirksamkeit von Schutzmaßnahmen werden Ausbreitungsrechnungen mithilfe verschiedener Modelle durchgeführt. Es werden zunehmend komplexere Berechnungsmodelle eingesetzt, die verlässlichere Prognosen liefern und helfen sollen, die Risiken durch windgetriebene Ausbreitung von Gasen weiter zu reduzieren. Mit steigender Komplexität der Simulationsverfahren steigen allerdings auch der Aufwand für die Entwicklung und die anwendungsbezogene Evaluierung neuer Modelle. Mit den vorgestellten Arbeiten wollen die Autoren einen Beitrag zur Entwicklung und Bereitstellung frei verfügbarer numerischer Strömungs- und Transportmodelle leisten und speziell die Weiterentwicklung der im Bereich Auswirkungsbetrachtungen verwendeten Werkzeuge unterstützen. Der Artikel beschreibt erste Problemlösungen auf dem Weg zur Entwicklung entsprechender, frei verfügbarer und angemessen validierter Softwaretools.
Räumliche und zeitliche Variabilität der NO2– und Feinstaubkonzentrationen entlang einer verkehrsreichen Bundesstraße in Stuttgart/Spatial and temporal variability of NO2 and particulate matter concentrations along a busy federal highway in Stuttgart
Authors: Vogt Ulrich , Samad Abdul
Published: August 2021

Das Ziel der vorgestellten Studie bestand darin, Konzentrationen von Stickstoffdioxid (NO2), Partikeln (PM10 und PM2,5) und Black Carbon (BC) entlang eines ausgewählten Abschnittes der stark befahrenen Bundesstraße B14 zu untersuchen, die durch das Stadtgebiet von Stuttgart verläuft. Dafür wurde die Verteilung verschiedener luftverunreinigender Komponenten sowohl zeitlich als auch räumlich hochaufgelöst erfasst. Sie wurden in einer ersten Messkampagne von April bis Juni 2014, in einer zweiten Messkampagne von Mitte März bis Ende April 2015 und in einer dritten Messkampagne im Februar 2017 mithilfe mobiler Messungen entlang einer festen, für Radfahrer zugänglichen Messroute gemessen. Ergänzt wurden die mobilen Messungen durch NO2– und NOX-Passivsammlermessungen an ausgewählten Messstandorten. Die NO2– und Feinstaub-Konzentrationen werden stark von den Emissionen des Straßenverkehrs beeinflusst. Die Abnahme der Schadstoffkonzentrationen mit zunehmendem Abstand zur Bundesstraße konnte durch Vergleichsmessungen in einem Park quantifiziert werden. Es wurden zusätzlich Vertikalprofile für Stickstoffoxide (NOX, NO, NO2) sowohl kontinuierlich mit Chemilumineszenz-Messgeräten als auch mit Passivsammlern in verschieden Höhen gemessen, um die Abnahme der NO2-Konzentration mit der Höhe zu untersuchen.

The purpose of the paper is to define meaning and content of consent in criminal offenses against sexual freedom and sexual inviolability of a person provided for in Section IV of the Criminal Code of Ukraine.
Results. The paper establishes that lack of consent is a constructive sign of rape (article 152 of the Criminal Code), sexual violence (article 153 of the Criminal Code) and coercion to have sexual intercourse (article 154 of the Criminal Code). The ways of solving arisen problems during the qualification of situations in which a person mistakenly believes that consent was given, as well as when consent was not given explicitly, have been determined. It is recommended to clarify the content of "voluntary consent" by indicating in the note to Article 152 of the Criminal Code, actions which shall not indicate voluntariness of consent. The paper notes that using the collocation "without voluntary consent" is superfluous in Articles 153 and 154 of the Criminal Code, since "coercion" and "violence" also indicate absence of voluntary consent. It has been established that consent is a distinguishing feature of a criminal offense provided for in Article 155 of the Criminal Code from Articles 152 and 153 of the Criminal Code, thus sexual intercourse with a person from 14 to 16 years with her consent indicates the commission of a criminal offense under Art. 155 of the Criminal Code. It is proposed to supplement Article 155 of the Criminal Code with the clause “in the absence of signs of criminal offenses under Art. 152 and art. 153 of the Criminal Code”.
Conclusion. The paper provides that consent shall be both constructive and distinguishing feature of criminal offences against sexual freedom and sexual inviolability. Several problems of consent in such crimes are defined as well as ways of their solution.
Essence and criteria for recognition of assets in account and reporting
Authors: GULIEV Vagif
Published: August 2021

The purpose of the paper is to study the issues of disclosure and interpretation in economic sciences and accounting of the essence of the concepts of "assets" and "capital", substantiation of their own judgments on these concepts.
Research methodology – methods of description, comparison, formalization, abstraction, analysis and synthesis were used in the work.
The meaning of the study is the expression of objects common for all economic sciences in different concepts and the assignment of different functions to them lead to discrepancies in the economic language, and, consequently, to a gap in the theory and methodology of forming and evaluating information about the same objects. Therefore, it is important to correctly disclose and formulate problematic issues that exist in the area under consideration. Research results can be used and applied to unify economic concepts, to better understand and evaluate information about the activities of institutional units.
As a result of the study, it was revealed that in the accounting literature and regulatory documents, assets are defined and recognized only as a source of income or economic benefit, and the accounting and reporting methodology is based on the relevant definitions and recognition criteria. It is substantiated that when formulating the semantics of the concept of "assets" and recognizing objects in reporting as assets, it is necessary to take into account both their economic and social functions. Further development of the accounting methodology should proceed on the basis of this concept.
Originality and scientific novelty of the research – an attempt is made to prove that in the accounting and reporting system, the concept of "Assets" should be accepted as content, and the concepts of "Capital" and "Liabilities" – as a form, that is, as ownership rights over assets under the control of companies.

Introduction. Knowledge of the causes and nature of emergencies allows for the early adoption of protective measures with reasonable behaviour to reduce all types of damage significantly. Preliminary information for business structures makes it possible to carry out preventive work, alert forces and means, explain to people the rules of conduct. All business structures and the population must be ready to act in extreme situations, participate in the elimination of natural disasters, accidents and catastrophes, to master the methods of providing first aid to victims. To address these issues, most developed countries in Europe and America have established unique medical systems, the main tasks of responding to emergencies and participating in eliminating health consequences.
The purpose of the paper is to study the level of emergencies in Ukraine and develop preventive measures for business structures.
Results. In 2020, 116 emergencies were registered in Ukraine, including 40.2% of man-made nature; natural nature – 54.7%; social nature – 5.1%. The human disease was also significantly affected by the COVID-19 coronavirus - 18,680 deaths in 2020. Compared to 2019, the total number of emergencies in 2020 decreased by 20.5%. The analysis showed that the most common sources of man-made emergencies are fires and explosions that occur at industrial facilities, so the authors proposed precautionary measures for business structures, which include measures to address the causes that could lead to the occurrence of fire (explosion), to limit (localize) the spread, to create conditions for the evacuation of people and property, timely detection of fire and notification of it, extinguishing the fire, maintaining the fire fighting forces in constant readiness.
Conclusion. The study showed that the number of emergencies is small and can be observed in some species in 2020, but each emergency is a human life, so it is necessary to strive for their number to lead to 0. The proposed measures will allow businesses to anticipate emergencies more effectively.

Perairan Laut Maluku memiliki hubungan kuat dengan Samudera Pasifik yang mengakibatkan maraknya kegiatan Illegal Unregulated and Unreported Fishing (IUU-Fishing). Patroli keamanan laut dalam rangka mengatasi IUU-Fishing saat ini masih mengandalkan informasi dari nelayan setempat yang diterima oleh pangkalan TNI AL terdekat, metode ini tentunya kurang efektif dan efisien. Penelitian ini menggunakan data sekunder akuisisi satelit klorofil-a level 3 dengan analisis korelasi pergeseran waktu yang digunakan untuk menentukan tingkat kesesuaian hubungan antara hasil tangkapan skipjack tuna dan konsentrasi klorofil-a, hal ini diperlukan untuk menganalisis hasil tangkapan tuna, termasuk hubungannya dengan klorofil-a secara spasial. Analisis terhadap data tersebut dapat mengidentifikasi dan menjadwalkan waktu terbaik untuk patroli keamanan laut. Hasil awal menunjukkan efektivitas operasi keamanan laut untuk simulasi selama lima tahun (Desember 2010 - November 2015). Hasil tangkapan skipjack tuna dipengaruhi oleh distribusi klorofil-a dengan koefisien korelasi sebesar (-0,31) dengan jeda waktu satu bulan.

Published: August 2021

The study aimed to reveal the research trends of articles related to PBL in chemistry education and to provide insights into the characteristics of the research activities through bibliometric and descriptive content analyses. For bibliometric analysis, a total of 119 articles were accessed from the Web of Science (WoS), and for descriptive content analysis, a total of 30 articles were eliminated from the “Education & Educational Research” category of WoS. In bibliometric analysis, author keywords, words in the abstracts, citation analyses, and co-citation analyses in the articles were analyzed to reveal an overall picture in the related literature. Then, a descriptive content analysis was performed to examine in detail the fields of research, variables, methods, sample groups, data collection tools, data analysis methods, and the results highlighted in the articles. The bibliometric analysis results showed that the most-used keywords were problem-solving/decision making, problem-based learning, undergraduate, inquiry-based/discovery learning, laboratory instruction, and collaborative/cooperative learning. The most used words in the abstracts of the articles were a problem, students, learning, study, course, approach, skill, and chemistry. The most cited authors were Leman Tarhan, Santiago Sandi-Urena, Melanie M. Cooper, and Todd A. Gatlin. The top two journals in the terms of the total number of articles and the most cited were “Journal of Chemical Education” and “Chemistry Education Research and Practice”. The descriptive content analysis results showed that undergraduate chemistry laboratories and chemistry courses were the main learning environments for PBL settings in chemistry education. Undergraduate students were the most frequently preferred sample. The most examined variables in the articles were academic achievement, views about PBL and attitude. Quantitative and qualitative studies were the main research focus, but there was a limited number of mixed studies. Also, interviews, achievement tests, and alternative assessment tools were widely used as data collection tools in the articles.

We develop a new method based on Gaussian processes to reconstruct the mass distribution of binary black holes (BBHs). Instead of prespecifying the formalisms of mass distribution, we introduce a more flexible and nonparametric model with which the distribution can be mainly determined by the observed data. We first test our method with simulated data and find that it can well recover the injected distribution. Then, we apply this method to analyze the data of BBHs’ observations from LIGO-Virgo Gravitational-Wave Transient Catalog 2. By reconstructing the chirp mass distribution, we find that there is a peak or a platform located at 20–30 M
⊙ rather than a single-power-law-like decrease from low mass to high mass. Moreover, one or two peaks in the chirp mass range of

may be favored by the data. Assuming a mass-independent mass ratio distribution of p(q) ∝ q
1.4, we further obtain a distribution of primary mass and find that there is a feature located in the range of (30, 40) M
⊙, which can be related to Broken Power Law and Power Law + Peak distributions described in Collaboration et al. Besides, the merger rate of BBHs is estimated to be
