Published: March 2022

The SARS-Cov-2 outbreak caused by a coronavirus infection shocked dozens of countries. This disease has spread rapidly and become a new pandemic, a serious threat and even destroys various sectors of life. Along with technological developments, various deep learning models have been developed to classify between Covid-19 and Normal X-ray images of lungs, such as Inception V3, Inception V4 and MobileNet. These models have been separately reported to perform good classification on Covid-19. However, there is no comparison of their performance in classifying Covid-19 on the same data. This research aims to compare the performance of the three mentioned deep learning models in classifying Covid-19 based on X-ray images. The methods involve data collection, pre-processing, training, and testing using the three models. According to 2,169 dataset, the InceptionV3 model obtained an average accuracy value of 99.62%, precision value 99.65%, recall value 99.5%, specificity value 99.5%, and f-score value 99.52%; while the InceptionV4 model obtained an average accuracy value of 97.79%, precision value 98.11%, recall value 90.18%, specificity value 90.18%, and f-score value 97.25%; and the MobileNet model obtained an average accuracy value of 99.67%, precision value 99.77%, recall value 99.38%, specificity value 99.38%, and f-score value of 99.67%. The three models can classify the Covid-19 and Normal X-ray images based on research results, while the MobileNet model achieved the best performance.

Linking life cycle BIM data to a facility management system using Revit Dynamo
Authors: Thabet Walid , Lucas Jason , Srinivasan Sai
Published: March 2022

Facility management (FM) requires multidisciplinary activities, and thus has extensive information requirements. Much of that information is created during the design, construction, and commissioning phases of a project. Providing the owner of a facility with usable life cycle asset information after construction has been a challenge to the industry. Traditional methods of manually inputting data into FM systems are time consuming and error prone. Various automated approaches and workflows continue to be developed to respond to specific owner needs. This research developed a unique workflow that uses Dynamo within Revit to automatically extract asset management data from the model and export the data to a proprietary format required by the facility owner. The formatted spreadsheet allows for direct linking of the data to the owner's FM system, hence eliminating time wasted in manual data entry and avoiding missing any maintenance cycles that would result if the FM system is not populated with critical information in a timely manner. This article utilizes a case study approach to demonstrate this novel Dynamo workflow. The required case study asset data identified and captured include asset groups, their properties and attributes, and corresponding metadata. A basic three-dimensional representation of the facility and all its equipment are modeled in Revit and asset data are input to corresponding model elements. This article also describes the complexity of the owner's proprietary information needs and the resulting automated workflow that extracts and exports data from Revit into an Excel format that can directly link into the FM system.
Did the Pandemic Permanently Digitalize Higher Education in Bulgaria?
Authors: Getova Antoaneta , Mileva Eleonora
Published: March 2022

The pandemic of COVID-19 had a great impact on the educational systems in many countries, including Bulgaria. In the last three semesters, the educational process was held mostly online in the majority of the Bulgarian universities. The switch to online learning in Bulgaria was made very quickly and with no real preparation, which raised the question of whether it was effective enough. While considered as temporary, online learning continued three semesters, with the possibility of continuing even further, which leads to the question of whether the pandemic irreversibly changed higher education to a more digitalized, advanced, and practically new approach, and, most importantly: what are the perceptions of the participants in the educational process about all these unexpected changes?

The paper presents the results of an empirical online survey of the attitudes of lecturers and students toward the effects of online education, its advantages and disadvantages, and also its main problems. The sample consists of 224 students and 74 lecturers of different Bulgarian universities. The survey was made in 2021 and is a continuation of a pilot survey made during the first lockdown in Bulgaria in May 2020 by the same team.

Wiragawi Bamboo Music: the Representation of Commodification of Bamboo from the Structural Results at Three Locus. The purpose of this study is to describe the results of the commodification of Wiragawi Bamboo Music as a Representation of Structuring in Three Locus, among others, in West Java Province, Yogyakarta Special Region (DIY), and East Nusa Tenggara (NTT). This study uses a qualitative method with a deeper socio-cultural structuration, represented as a work in the form of commodification of bamboo as a musical instrument. The commodification of bamboo as a participatory of 'bamboo body grows' can legitimize an identity and regional authenticity as a form of cultural resilience based on a cultural economy. Bamboo plays an essential role in the cultural process, from birth to death according to its era, so it can be said that bamboo and humans have a close correlation, according to the locus of the area. Research findings include producing a set of Wiragawi bamboo musical instruments as a result of the commodification of bamboo music at three locuses, namely West Java Province, Yogyakarta Special Region (DIY), and East Nusa Tenggara (NTT). The conclusion shows that the primary material of bamboo is still very open to being a source of inspiration in creativity, mainly to produce various new instruments according to the interests and developments of the era.

Authors: Seiler Matthias , Engelen Andreas , Goffin Keith
Published: March 2022

Mid-sized businesses (MSB) and mid-sized B2B businesses (MSB2B) in particular are often ignored in the research on innovation management. Yet, MSBs are very important for the growth of economies worldwide and it is of utmost importance for their future performance to develop new products. For the successful development of new differentiated products in MSBs, the early identification and consideration of customers’ hidden needs is crucial. Techniques that can be used to generate customer insights are often referred to by the term voice of the customer (VOC). However, extant research has treated this term very inconsistently. This is why, it is difficult for MSBs to decide which techniques are most useful to them. For MSBs, that have limited resources, this is a particular issue and best practices of how MSBs identify their customers’ needs for different types and different phases of innovation projects are lacking.This review  aims at clarifying the aforementioned issues for MSB2Bs. Based on an analysis of the limited research on using hidden needs techniques in MSB2Bs, actionable recommendations are derived as to which hidden needs techniques are most useful for MSB2Bs and which best practices should be considered when developing new products in MSB2Bs. Opportunities for academia and practitioners are identified and managerial implications for industrial product innovation in MSB2Bs are discussed.

Буксировка «на усах» – сложнейшая морская операция. Недостаточное внимание к вопросу обеспечения прочности носовой оконечности может привести к повреждению судна и, как следствие – к невозможности дальнейшей буксировки в штатном режиме и необходимости аварийной буксировке, а также к последующему ремонту судна. Основной трудностью при расчете прочности носовой оконечности судна в районе контакта с кринолином ледокола является корректное определение нагрузок, возникающих в зоне контакта. Целью исследования является обзор существующих методик подобных расчетов и анализ их применимости для выполнения оперативных оценок прочности судов в эксплуатации. Математические модели буксировки судов «вплотную», методики расчета нагрузки в зоне контакта судна с кринолином ледокола. Выполнен обзор и анализ существующих методик определения усилия, возникающего к зоне контакта судна с кринолином ледокола. Из рассмотренных методик наиболее подходящей для поставленных задач в исследовании является методика Купермана. В первом приближении эту нагрузку можно принимать как расчетную при оценке прочности носовой оконечности, однако в дальнейшем возможно уточнение влияния инерционной составляющей буксируемого судна на результирующее ускорение торможения тандема, а также учет демпфирующих свойств кранцевой защиты.

The appearance of the dominant digital revolution has led to a modification of social behaviour in all areas, posing new challenges to the Law that were until now unknown. This work constitutes a study of the requirements for gathering evidence, derived from the commission of crimes through computer media, its legality, and the way in which they are incorporated into criminal proceedings. In this context, it has been traditional in criminal doctrine and jurisprudence that an evidence, to be considered lawful, that is, ultimately valid, it must be brought to the process with a number of procedural guarantees, being the most relevant one the possibility to be subject to contradiction. It is in this light when computer expert, through their forensic practice, can be involved in order to confirm or deny the validity of potential evidence which, in turn, may relate to the charge or discharge of criminal proceedings.

Highlighting the important of the urban dimensions of this relationship, this research sheds light on agents usually invisibilized by the literature in an attempt to understand their role in land policy. The practices, meanings, and outcomes of the Armed Forces’ involvement is reflectedin the decision-making conditions that characterize Brazilian democracy. By establishing a dialogue with a well-known aphorism from Prussian strategist Carl von Clausewitz, that war is the continuation of politics by other means, we present and analyze land policies as continued by war operators. As we analyze military management practices and the commodification of public spaces, we find the city’s production dynamics are galvanized by Army generals. Beyond security, surveillance, and population control, the Armed Forces have carried out a complex set of strategies regarding the occupation of cities, fueling debates around the nature of democracy underway in contemporary Brazil.

Purpose. The article is devoted to the study of Bashkir toponyms formed on the basis of phytonyms. The main objective is to demonstrate phytotoponyms and determine the laws of their nomination.

Results. The authors describe models for the formation of toponyms derived from plant names and conduct a comparative analysis of Bashkir phytotoponyms with onomastic materials of other Turkic languages. Of the 10,000 Bashkir geographical names recorded, phytonyms are found in about 4 % of toponyms. They contain 65 names of plants, including 16 names of trees, 16 names of shrubs and fruit trees, 8 names of aquatic plants, 13 names of edible wild herbs, 13 names of other plants used for domestic purposes in everyday life, agricultural crops, etc.

Conclusion. The authors of the article emphasize that phytotoponyms ascertain, register the location, a certain position of the plant and belong to the secondary nomination, as well as the fact that many phytotoponyms carry socially significant cultural and historical information about the world, and in ancient times they would act as a natural landmark in space. Systematization of the collected material reveals the features of the vegetation cover and areal flora of Southern Urals and Trans-Urals.
On the Mythologization of Toponyms in the Language and Folklore of the Altaians
Authors: Oinotkinova N. R.
Published: March 2022

The paper is devoted to identifying the features of the mythologization of Altai place names. An ethnolinguistic approach to the subject of research using the methods of motivational and contextual analysis allowed to reveal the features of mythologized toponyms in Altai language and folklore. For toponyms that contain myths in their internal form mythologization occurs on the basis of lexical motivation which is also reinforced by the mythological text. Place names that do not contain myths in their internal form have only a mythological context. In the mythologization of toponyms an important role is played by the plots and motives known in world folklore about the flood, glaciation on the earth and the disappearance of some species of the animal world, the end of the world, theophany, and the struggle of man with a monster.
Pauses in Native and Foreign-Accented Spontaneous Speech: Acoustic Analysis of Native Chinese, Chinese Learners of Russian, and Native Russian Speech
Authors: Teng Hai , Androsova S. V.
Published: March 2022

The present study aimed to explore pause types and their fillers in Russian and Chinese native speech compared to the speech of Chinese bilinguals speaking Russian with a focus on universal and language-specific patterns. An acoustic study of 8 subjects has been performed: 4 Russian males speaking Russian, and 4 Chinese males speaking both Chinese and Russian. Acoustic measurements were performed using PRAAT and included pause count, pause duration, pitch direction, vocalic fillers formant values, and their duration. Descriptive statistics were used to determine count, mean, minimal, and maximal values. The results demonstrate that first, silent and filled pauses were used by all subjects with the preference for the silent pause strategy. For all Chinese subjects, the pause rate was considerably higher in native speech than in non-native Russian speech. Second, the universal pause fillers were [a]-like, [am]-like, and [m]-like ones. Simple fillers like [ɤ], [o] were language-specific for Chinese subjects. Another language-specific feature was the wide use of vowel groups by Chinese subjects. Finally, vowel + nasal (velar and forelingual) sequences like [ɤŋ] were language-specific for Chinese subjects.
To the Study of the Stishnoy Prologue Vocabulary: The Thematic Group of Artifact Nominations

Published: March 2022

The article examines a significant lexical layer of the Stishnoy Prologue which is the vocabulary of artifact names (i. e. ‘objects made by man’). The revealed vocabulary includes 23 thematic groups. Intra-word and inter-word paradigmatic relations were analyzed in the group of artifact nominations. The purpose of our study is a comprehensive analysis of the names of artifacts in the Stishnoy Prologue. An analysis of the functional features of the artifact names showed that the genre of the text presented in the Stishnoy Prologue defines the frequency of use of the analyzed lex emes. Analysis of the artifact names in the Stishnoy Prologue reveals that the group of such lexemes is quite diverse and includes not only names of objects of worship and church life and instruments of torture, but also units denoting everyday vocabulary such as names of jewelry, objects of crafts, etc. The frequency of use of such lexemes in the text of the manuscript and their semantic connections within and outside of the group indicate that the units belong to the active vocabulary of the Church Slavonic language of the 15th century.

Рассмотрена проблема виброизоляции кресла оператора строительно-дорожной машины при синусоидальных заданных перемещениях основания кресла. Данная проблема является весьма актуальной, поскольку значительные вибрации сопровождают работу строительно-дорожных машин, работающих с грунтом, грузами, дорожными покрытиями и т.п. Проблема была исследована с позиции влияния формы статической силовой характеристики подвески на максимальное виброускорение кресла. Подобную статическую характеристику имеют многие виброзащитные механизмы. Одним из перспективных направлений в развитии виброзащитных систем в настоящее время выступает применение систем с участком квазинулевой жесткости в статической силовой характеристике. Подобные системы лучше гасят низкочастотные вибрации. В настоящей работе были исследованы системы, имеющие трехсегментную статическую характеристику, средний сегмент которой представляет собой горизонтальную прямую, соответствующую участку квазинулевой жесткости. А два крайних сегмента, обеспечивающие торможение и остановку механизма при выходе за границы участка квазинулевой жесткости, были описаны сплайнами Эрмита с максимальной производной второго порядка...
