The Sociolinguistics of Kenyang Names: Phase One
Authors: Emilisco Jones Dr Enoachuo
Published: May 2021

Kenyang is a language spoken in the Manyu Division in the
South-West Region of the Republic of Cameroon in Central Africa. It has
an increasing population of over 65.000 speakers spread out across three
sub-divisions in two divisions of the South-West Region; Manyu division,
in Upper and Central parts; and Koupe Muanegouba, at the west part of
Nguti sub-division. The language is developing and has a written code
(Latin script) but dominated by English graphemes for popular readability.
Neighbouring languages result to three dialects; Upper Kenyang (“Kɛnyaŋ
mfay” or Haut Kenyang); Lower Kenyang (“Kɛnyaŋ Ntɛn” or BasKenyang), Lower Kenyang is the reference dialect. Its developing status is
endangered by the presence of the strong and influential spread of the
dominant world language (English). The concern of this paper is on
reconsidering the appellation of Kenyang proper names in view to revitalize
their connotations in the language. Considering the fact that naming in
Kenyang is a socio-cultural-bound phenomenon, these proper names have not only lost their
morphophonetic representation, but have lost its semantic properties. The proper or personal names
considered are randomly selected names of persons, and places in the central, lower and upper Banyang
in Manyu Division. What, and how are these names pronounced, written, and what do they signify given
these are not arbitrarily assigned names? Interviews of 10 elderly people and 6 young adults native
speakers in three villages of Upper, Central, and Lower Banyang and in three towns of Southwest;
Mamfe, Kumba, and Buea were conducted. An ethnogpraphic method through participant observation
and vox pops provided the data that is explained using the Quan-qualitative approaches. The result shows
that Kenyang proper names have been devalorised. Thus revitalisation is imperative since the language
is undergoing linguistic development.

New Approaches to OCR for Early Printed Books
Authors: Weichselbaumer Nikolaus , Seuret Mathias , Limbach Saskia , Dong Rui , Burghardt Manuel , Christlein Vincent
Published: May 2021

Books printed before 1800 present major problems for OCR. One of the main obstacles is the lack of diversity of historical fonts in training data. The OCR-D project, consisting of book historians and computer scientists, aims to address this deficiency by focussing on three major issues. Our first target was to create a tool that identifies font groups automatically in images of historical documents. We concentrated on Gothic font groups that were commonly used in German texts printed in the 15th and 16th century: the well-known Fraktur and the lesser known Bastarda, Rotunda, Textura und Schwabacher. The tool was trained with 35,000 images and reaches an accuracy level of 98%. It can not only differentiate between the above-mentioned font groups but also Hebrew, Greek, Antiqua and Italic. It can also identify woodcut images and irrelevant data (book covers, empty pages, etc.). In a second step, we created an online training infrastructure (okralact), which allows for the use of various open source OCR engines such as Tesseract, OCRopus, Kraken and Calamari. At the same time, it facilitates training for specific models of font groups. The high accuracy of the recognition tool paves the way for the unprecedented opportunity to differentiate between the fonts used by individual printers. With more training data and further adjustments, the tool could help to fill a major gap in historical research.

Exact BER Analysis of NOMA with Arbitrary Number of Users and Modulation Orders
Authors: Yahya Hamad , Alsusa Emad , Al-Dweik Arafat
Published: May 2021

Non-orthogonal multiple access (NOMA) is a promising candidate for future mobile networks as it enables improved spectral-efficiency, massive connectivity and low latency. This paper derives exact and asymptotic bit error rate (BER) expressions under Rayleigh fading channels for NOMA systems with arbitrary number of users and arbitrary number of receiving antennas and modulation orders, including binary phase-shift keying and rectangular/square quadrature amplitude modulation. Furthermore, the power coefficients' bounds, which ensure users' fairness, and solve the constellation ambiguity problem, are derived for N=2 and 3 users cases with any modulation orders. In addition, this paper determines the optimal power assignment that minimizes the system's average BER. These results provide valuable insight into the system's BER performance and power assignment granularity. For instance, it is shown that the feasible power coefficients range becomes significantly small as the modulation order, or N, increases, where the BER performance degrades due to the increased inter-user interference. Hence, the derived expressions can be crucial for the system scheduler in allowing it to make accurate decisions of selecting appropriate N, modulation orders, and power coefficients to satisfy the users' requirements. The presented expressions are corroborated via Monte Carlo simulations.
Falsifying Cyber-Physical Systems – a Hybrid Optimization-Free and an Optimization-Based Line-Search Approach
Authors: Ramezani Zahra , Claessen Koen , Smallbone Nicholas , Fabian Martin , Åkesson Knut
Published: May 2021

Cyber-physical systems (CPSs) are complex and exhibit both continuous and discrete dynamics, hence it is difficult to guarantee that they satisfy given specifications, i.e., the properties that must be fulfilled by the system. Falsification of temporal logic properties is a testing approach that searches for counterexamples of a given specification, which can be used to increase the confidence that a CPS does fulfill its specifications. Falsification can be done using random search methods or optimization methods. In this paper, a method based on combining random parameters together with considering extreme combinations of parameter values is proposed. Evaluation results on benchmark problems show that this method performs well on many of the problems. Optimization methods are needed when optimization-free methods do not perform well in falsification. The efficiency of the falsification is affected by the optimization methods used to search for inputs that might falsify the specifications. This paper presents a new optimization method for falsification, Line-search falsification, where optimization is done over line segments through a vector of inputs in the n-dimensional parameter space. The evaluation results on the benchmark problems show that using this method improves the falsification performance by reducing the number of simulations necessary to falsify a specification.
Engineering Reflective Metasurfaces with Ising Hamiltonian and Quantum Annealing
Authors: Ross Charles , Gradoni Gabriele , Lim Qi Jian , Peng Zhen
Published: May 2021

We present a novel and flexible method to optimize the phase response of reflective metasurfaces towards a desired scattering profile. The scattering power is expressed as a spin-chain Hamiltonian using the radar cross section formalism. For metasurfaces reflecting an oblique plane wave, an Ising Hamiltonian is obtained. Thereby, the problem of achieving the scattering profile is recast into finding the ground-state solution of the associated Ising Hamiltonian. To rapidly explore the configuration states, we encode the Ising coefficients with quantum annealing algorithms, taking advantage of the fact that the adiabatic evolution efficiently performs energy minimization in the Ising model. Finally, the optimization problem is solved on the D-Wave 2048-qubit quantum adiabatic optimizer machine for binary phase as well as quadriphase reflective metasurfaces. Even though the work is focused on the phase modulation of metasurfaces, we believe this approach paves the way to fast optimization of reconfigurable intelligent surfaces that are mod- ulated in both amplitude and phase for multi-beam generation in and beyond 5G/6G mobile networks.

Can we imitate stock price behavior to reinforcement learn option price?
Authors: Jin Xin
Published: May 2021

This paper presents a framework of imitating the price behavior of the underlying stock for reinforcement learning option price. We use accessible features of the equities pricing data to construct a non-deterministic Markov decision process for modeling stock price behavior driven by principal investor's decision making. However, low signal-to-noise ratio and instability that appear immanent in equity markets pose challenges to determine the state transition (price change) after executing an action (principal investor's decision) as well as decide an action based on current state (spot price). In order to conquer these challenges, we resort to a Bayesian deep neural network for computing the predictive distribution of the state transition led by an action. Additionally, instead of exploring a state-action relationship to formulate a policy, we seek for an episode based visible-hidden state-action relationship to probabilistically imitate principal investor's successive decision making. Our algorithm then maps imitative principal investor's decisions to simulated stock price paths by a Bayesian deep neural network. Eventually the optimal option price is reinforcement learned through maximizing the cumulative risk-adjusted return of a dynamically hedged portfolio over simulated price paths of the underlying.
Squeezed Protection in Elastic Optical Networks Subject to Multiple Link Failures
Authors: Assis Karcius , Almeida Raul , Dias Leonardo , Waldman Helio
Published: May 2021

Elastic optical network (EON) is fast becoming a key solution for designing optical network with better usage of spectrum resources or other objectives of interest to tenant and/or operators. A primary concern of EONs is to protect the network against failures of its elements, because this kind of event can provoke the loss of substantial amount of traffic. In this paper, we propose a new mixed integer linear programming (MILP) formulation for protecting the network traffic against multiple link failures. The key idea is to use bandwidth squeezing together with grooming capability to provide few extra traffic for protection and guarantee a minimum bandwidth for each source–destination node pair under multiple failure events. The proposed formulation solves the virtual topology design problem jointly with the grooming, routing, modulation and spectrum allocation (RMSA) tasks. Due to the non-deterministic polynomial time (NP-hard) nature of the proposed MILP formulation, a heuristic strategy (referred to as two-step MILP) for large networks is also proposed. The solutions and performance of the proposed MILP formulation and two-step MILP analyzed through case studies in a small network. In addition, the performance of three large networks is assessed for cases scenarios where connections are under different service-level agreement (SLA). In view of proposed formulation and two-step MILP, it is possible to identify the configurations that ensure better usage of spectrum resources with different kinds of protection against single or multiple link failures.
Cross-Layer Analysis of Multi-Static RFID Systems Exploiting Capture Diversity
Authors: Valentini Roberto , Di Marco Piergiuseppe , Alesii Roberto , Santucci Fortunato
Published: May 2021

In this paper, we propose a framework for cross-layer analysis of multi-static passive RFID systems. The model takes into account details of the shared wireless channel, including fading and capture effect, whereas, at the medium access control (MAC) layer, the anti-collision mechanism proposed in the EPC Generation 2 standard is taken as a reference.
To address the complexity of the system model, we rely on a semi-analytical approach, that combines a moment matching approximation method to abstract the physical layer and Monte-Carlo simulations to describe the MAC dynamics.
Furthermore, based on the space diversity feature offered by the multi-static settings, we introduce the concept of capture deiversity and propose a modification to the standard to fully support this form of diversity.
Numerical results show the impact of deployment conditions and the relative positions of interrogator, tags, and detection points on the performance of tags' identification. We show how the number of detection points impacts the system performance under various channel conditions and MAC parameters' settings. Finally, we validate the proposed update of the MAC protocol, showing substantial performance improvement with respect to the standard collision resolution policy.
Algorithm for the Fewest Arms Required by Multi-Band Linear Dipole Antenna
Authors: Xiao Bing
Published: May 2021

Small linear dipole antennas with a multi-band characteristic are necessary for many strip or bar shaped gateway devices of the Internet of Things (IoT), for the connectivity in various communication protocols. However, the conventional methodology of designing multi-band dipole antennas is generally empirically based. More frequency bands usually mean even more arms/slots, which results in an increasingly bulky antenna. In this paper, we will introduce an algorithm of using the fewest arms to design a multi-band linear dipole antenna. This algorithm is based on sharing arms after the effective ranges of mode excitation are determined by characteristic mode analysis (CMA). By this algorithm, an exemplified designed penta-band dipole antenna is effective in covering 433, 868, 1176, 1575, and 2450 MHz bands for LPWAN, GNSS, and ISM applications, with only 2.5 pairs of arms. 50% of arms are reduced in comparison to traditional methods. This algorithm is convenient in practical dipole antenna design, and greatly simplifies the antenna structure so that they could be mounted into small IoT devices.

Streaming Algorithms for Subspace Analysis: an Edge- and Hardware-oriented review
Authors: Marchioni Alex , Prono Luciano , Mangia Mauro , Pareschi Fabio , Rovatti Riccardo , Setti Gianluca
Published: May 2021

Subspace analysis is a basic tool for coping with high-dimensional data and is becoming a fundamental step in early processing of many signals elaboration tasks. Nowadays trend of collecting huge quantities of usually very redundant data by means of decentralized systems suggests these techniques be deployed as close as possible to the data sources. Regrettably, despite its conceptual simplicity, subspace analysis is ultimately equivalent to eigenspace computation and brings along non-negligible computational and memory requirements. To make this fit into typical systems operating at the edge, specialized streaming algorithms have been recently devised that we here classify and review giving them a coherent description, highlighting features and analogies, and easing comparisons. Implementation of these methods is also tested on a common edge digital hardware platform to estimate not only abstract functional and complexity features, but also more practical running times and memory footprints on which compliance with real-world applications hinges.

Políticas de desenvolvimento e da natureza: a pesca artesanal no processo de ambientalização da política pesqueira no Brasil
Authors: Cyrino Carolina , Trigueiro Aline
Published: May 2021

This article approaches the environmentalization of fisheries policy carried out by the Brazilian Institute of the Environment and Renewable Natural Resources (IBAMA), between 1989 and 1998, and outlines its repercussions, including the penalization that this brought to artisanal fishing. We consider as environmentalization the way in which sustainable development (SD) ideals were incorporated into the body of Brazilian environmental policy (during the 1990’s), promoting deep consequences in the regulatory policy toward artisanal fishing, by means of a technical justification (in ecological terms) to the modernization of the sector. However, this demand for modernization had already started in the 1920's, when fishing colonies were created by Brazilian Navy, but it gained a new direction with IBAMA’s performance. As a result the fishing population was stigmatized, instituting an increase in the means of control over their lives, techniques and artisanal knowledge.

A gyro-stabilizer is the interesting system that it can apply to marine vessels for diminishes roll motion. Today it has potentially light weight with no hydrodynamics drag and effective at zero forward speed. The twin-gyroscope was chosen. Almost, the modelling for designing the system use linear model that it might not comprehensive mission requirement such as high sea condition. The non-linearity analysis was proved by comparison the results between linear and non-linear model of gyro-stabilizer throughout frequency domain also same wave input, constrains and limitations. Moreover, they were cross checked by simulating in time domain. The comparison of interested of linear and non-linear close loop model in frequency domain has demonstrated the similar characteristics but gave different values at same frequency obviously. The results were confirmed again by simulation in irregular beam sea on time domain and they demonstrate the difference of behavior of both systems while the gyro-stabilizers are switching on and off. From the resulting analysis, the non-linear gyro-stabilizer model gives more real results that correspond to more accuracy in a designing gyro-stabilizer control system for various amplitudes and frequencies operating condition especially high sea condition.

Процес інтеграції України в міжнародну спільноту супроводжується ратифікацією міжнародних правових документів, упровадженням міжнародних стандартів, узгодженням національного та міжнародного законодавства, використанням найкращої світової практики. Такі процеси відбуваються також у сфері контролю та аудиту державних фінансів. Означені процеси непрості й неоднозначні. Усі країни мають свої власні проблеми, типові саме для них, тож підходи до аудиту та контролю відрізняються. Нині дуже актуальним стає питання дослідження вдосконалення процесу внутрішнього аудиту в Міністерстві оборони України через гармонізацію національних стандартів із міжнародними стандартами внутрішнього аудиту. Саме тому в статті чітко висвітлено ключові поняття впровадження пропозицій та вдосконалення механізму внутрішнього аудиту згідно з міжнародними стандартами внутрішнього аудиту в Міністерстві оборони України.

Aim: The role of tumor burden (TB) for patients with non-small cell lung cancer (NSCLC) receiving immunotherapy is still unknown. The aim of this analysis was to analyze the prognostic value of TB in a real-world sample of advanced NSCLC patients.
Methods: Sixty-five consecutive patients with advanced NSCLC treated with immunotherapy as first or second line therapy were retrospectively analyzed between August 2015 and February 2018. TB was recorded at baseline considering sites and number of metastases, thoracic vs. extrathoracic disease, measurable disease (MD) vs. not-MD (NMD) and evaluating dimensional aspects as maximum lesion diameter (cut-off = 6.3 cm), sum of the 5 major lesions diameters (cut-off = 14.3 cm), and number of sites of metastases (cut-off > 4). All cut-offs were calculated by receiver operating characteristic curves. Median overall survival (OS) was estimated using Kaplan-Meier method. A Cox regression model was carried out for univariate and multivariate analyses.
Results: Median age was 70 years and most patients (86.2%) had a good performance status (PS-Eastern Cooperative Oncology Group < 2). No significant difference in OS was noted between subgroups of patients according to TB. Bone metastases (BM) had a negative prognostic impact [median OS (mOS), 13.8 vs. 70.0 months, P = 0.0009; median progression free survival in the second line (mPFS2) 2.97 vs. 8.63 months; P = 0.0037]. Patients with NMD had a poorer prognosis (mOS, 15.9 months vs. not reached, P < 0.0001; mPFS2 3.8 vs. 12.2 months; P = 0.0199). Patients with disease limited to the thorax had a better prognosis compared to patients with involvement of extrathoracic sites (mOS, 70 vs. 17.3 months; P = 0.0136). Having more than 4 metastatic sites resulted as a negative prognostic factor (mOS, 15.9 vs. 25.2 months; P = 0.0106). At multivariate analysis, BM, NMD, extrathoracic disease and number of sites of metastases > 4 were negative prognostic factors (P < 0.0001).
Conclusions: This study underlines the negative prognostic impact of specific metastatic sites, presence of NMD and extrathoracic disease in advanced NSCLC patients treated with immunotherapy. However, TB does not appear to affect the outcome of these patients.
ПСИХОЛОГІЧНА ПАРАДИГМА СЕЛФІ У ВІРТУАЛЬНИХ СОЦІАЛЬНИХ МЕРЕЖАХ: ПОЗИТИВИ ТА НЕГАТИВИ БЛАГОПОЛУЧЧЯ ОСОБИСТОСТІ

У доповіді проаналізовано феномен селфі як наслідок поступового збільшення соціальної дистанції між людьми, відповідного перенесення реального життя у віртуальний простір і вибуху так званого «кліпового мислення», коли лайки та світлини заміняють глибші форми комунікації, притаманні старим формам епістолярного жанру. Описано також емпіричне дослідження певних особливостей самоставлення та нарцисизму студентської молоді, які проявляються через наявність або відсутність селфі-активності. Виявлено, що серед українського студентства селфіманія не отримала загрозливих розмірів, як це засвідчують зарубіжні дослідження, хоча і має певні негативні наслідки для особистісного стану. З’ясовано, що в цілому певна адаптивна селфі-активність студентів (до 10 світлин на тиждень) з викладенням їх у соціальних мережах не є шкідливою, навпаки, сприяє зниженню соціальної ізольованості, особливо в умовах переважання віртуальних контактів в часи вимушеного карантину. Проаналізовано позитивні аспекти селфі-активності (можливість самореалізації, покращення матеріального становища, один із засобів досягнути соціального успіху, популярності; можливість для самовираження, пізнання себе, підвищення самооцінки; розвиток творчого потенціалу; спілкування без меж, спосіб познайомитися з іншими) та негативні (селфі-адикція, заохочення духовної ліні, плекання поверховості, удавана само-реалізація, подоба осмисленості, оманливе благополуччя, розвиток селфізму, відмова від реального спілкування, зниження самооцінки, фальшиве «Я», залежність від «лайків», психотравматичні епізоди, Інтернет-булінг, секстинг, харасмент). Феномен селфі в сучасних умовах усе більше пов’язаний із особистісним та сексуальним благополуччям. Зазвичай сексуальне благополуччя природно розглядати в контексті парних стосунків чи взаємодій. Однак, у віртуальному середовищі «парна взаємодія» відбувається з кожним, хто розглядає представлене на всезагальний огляд зображення в соцмережах з метою отримання позитивної реакції.
Vorbeugender Brandschutz erreicht eine neue Dimension
Authors: Lange Jannis , Schwertfeger René
Published: May 2021

Funken, Glutnester und heiße Partikel können in Produktionsbetrieben unkalkulierbare Brandrisiken darstellen. Es ist anerkannter Stand der Technik, dass heiße Partikel, Brände und Explosionen in Bearbeitungsmaschinen und Filtern erst ab einer Eigentemperatur von 400 °C aufwärts erzeugen können. Zu beachten ist jedoch, dass produktionsbedingt Glutnester, die zunächst eine geringere Temperatur aufweisen, durch Sauerstoffzufuhr aufglimmen können, ihre Temperatur über die kritische Schwelle von 400 °C steigt und sie dann zum Zündpotenzial für einen Großschaden werden. Dies ist überall dort der Fall, wo große Luftbewegungen stattfinden, wie z. B. in pneumatischen Transportsystemen oder in Trocknungsanlagen.

Erfahrungen aus der Prüfung einer Kernfusionsanlage als Ex-Anlage nach BetrSichV
Authors: Uhlmann Michaela , Hübner Jochen , Ploeckl Bernhard , Kilian Sandra
Published: May 2021

Das Max-Planck-Institut für Plasmaphysik in Garching bei München untersucht mit dem Tokamak ASDEX Upgrade (AUG) die Grundlagen für ein Fusionskraftwerk, welches Energie aus der Kernfusion gewinnen soll. Bedingt durch den Einsatz von Wasserstoff und Deuterium sind Teile der Anlage in explosionsgefährdete Bereiche eingestuft, wodurch die Anlage der Prüfpflicht nach BetrSichV unterliegt. Aus Sicht des Explosionsschutzes liegt die Herausforderung darin, den Spagat zwischen der Forschung, d.h. einer ständigen Weiterentwicklung der Versuchsanlage, und einem beständigen Explosionsschutzkonzept unter Berücksichtigung des Stands der Technik zu bewältigen. Dieser Beitrag beschreibt die Anforderungen an die Prüfung einer Ex-Anlage nach BetrSichV am Beispiel einer komplexen Anlage, die nicht dem industriellen Standard entspricht. Der erste Teil befasst sich mit dem Prüfablauf und dem Explosionsschutzkonzept mit Maßnahmen zur Vermeidung der Bildung gefährlicher explosionsfähiger Gemische am Beispiel der Pellet-Zentrifuge. Der zweite Teil thematisiert darüber hinaus Inertisierungseinrichtungen, den Aspekt der funktionalen Sicherheit sowie Maßnahmen zur Vermeidung wirksamer Zündquellen (Geräte, Sicherheits-, Kontroll- und Regelvorrichtungen, Erdung, Blitzschutz) am Beispiel des Torus und des Vakuumpumpsystems.
Fritsch–Buttenberg–Wiechell rearrangement of magnesium alkylidene carbenoids leading to the formation of alkynes

A series of 1-heteroatom-substituted vinyl p-tolyl sulfoxides were prepared and treated with organometallic reagents to evaluate which combination of sulfoxides and organometallic reagents yielded alkynes the most efficiently. The use of 1-chlorovinyl p-tolyl sulfoxide and isopropylmagnesium chloride was optimal for this purpose. A variety of 1-chlorovinyl p-tolyl sulfoxides were prepared from carbonyl compounds and chloromethyl p-tolyl sulfoxide and were converted into alkynes via the sulfoxide/magnesium exchange reaction and subsequent Fritsch–Buttenberg–Wiechell (FBW) rearrangement of the resulting magnesium alkylidene carbenoids. The mechanism of the FBW rearrangement of magnesium alkylidene carbenoids was studied by using 13C-labeled sulfoxides and by using DFT calculations.
