Analysis of Partial Mitochondrial COI and 16S rRNA Gene Sequences Variation of Pagurus brachiomastus and Pagurus proximus (Decapoda: Paguridae) Populations from the South of Russian Far East
Authors: Atopkin Dmitry M.
Published: May 2023

Mitochondrial COI and 16S rRNA gene partial sequences were generated for Pagurus brachiomastus from two locations and P. proximus from single location of the south of Russian Far East. Genetic variation and differentiation of P. brachiomastus Russian and South Korean (GenBank data) populations were estimated and compared on the basis of sequence data on two mitochondrial genes separately. Additionally, P. simulans from South Korea was analyzed. Results show P. brachiomastus from two locations of the south of Russian Far East and South Korea and Korean P. simulans differs at intraspecific level based on molecular markers. Median-Joining analysis indicate presence of two main groups of haplotypes, representing P. proximus and P. brachiomastus + P. simulans, respectively. These data support that P. brachiomastus and P. simulans are conspecific. Mismatch distribution analysis showed population growth for P. brachiomastus at the south of Russian Far East. Sequence pairwise variations of both molecular markers appear differently in two far eastern samples of P. brachiomastus, that can be partially explained by active gene flow through hermit crab migrations between two localities after their isolation.

Experimental Research on Performance Development of Direct Injection
Hydrogen Internal Combustion Engine with High Injection Pressure

Published: May 2023

As a carbon-free power with excellent performance, the direct injection (DI)
hydrogen-fueled internal combustion engine (H2-ICE) has the potential
to contribute to carbon dioxide (CO2)-neutral on-road transport
solutions. Aiming at high thermal efficiency, the influences of key factors on
thermal efficiency over wide operating conditions of a turbocharging DI
H2-ICE were investigated under the lean-burn strategy. And the
nitrogen oxides (NOx) emission characteristics region was clarified
in the high efficiency. The results confirm the optimal ignition strategy with
the CA50 of 8–9 crank angle degrees after top dead center (°CA ATDC). The
late-injection strategy manifests a significant advantage in brake thermal
efficiency (BTE) compared with the early-injection strategy, and this advantage
can be amplified by the increased load or injection pressure. The effects of
injection (EOIs) pressure on BTE exhibit different laws at different EOIs. Under
the early-injection strategy, the lower injection pressure improves BTE due to a
more sufficient mixing. While under the late-injection strategy with strong
mixture stratification, the high injection pressure conditions exhibit a higher
BTE due to reduced compression work. In terms of air-fuel ratio, the BTE is
improved monotonically with increased λ at low and medium loads. But there is an
optimal λ value limited by the oxygen concentration at a high load. The
late-injection strategies with high BTE perform a high level of NOx
emissions, which confirms the strong trade-off relationship between the thermal
efficiency and NOx emissions of H2-ICEs. A moderate
late-injection strategy with an EOI of about 40°CA BTDC can significantly reduce
the NOx emissions with a slight loss in BTE. The injection pressure
shows different effects on NOx emissions in different EOI ranges,
depending on the mixture distribution. In addition, ultra-lean burn and lower
intake temperature are effective means to reduce NOx emissions
without losing thermal efficiency.
Investigation Effects of Pre-chamber Volume Variations on the
Performance of a Natural Gas Lean-Burn Engine
Authors: Talei Mehdi , Jafarmadar Samad , Amini Niaki Seyed Reza
Published: May 2023

The pre-chamber ignition system accelerates combustion efficiently by supplying
multiple ignition points, high ignition energy, and strong turbulent
disturbance. This system expands the lean combustion limit and improves
combustion stability on natural gas engines. This work studied the effects of
pre-chamber volume variations on combustion, performance, and emission behaviors
of a natural gas lean-burn engine under experimental and numerical methods.
Results show an increase in the pre-chamber volume from 0.3% to 4.4% of
compression volume can increase the in-cylinder pressure in single-stage
combustion. The energy and exergy efficiency of the engine Model-1.3% increased
up to 43.7% and 41.9%, respectively, which are the highest values among the
prepared models. Simultaneously, the model heat loss with the maximum
pre-chamber volume was two times higher than the minimum pre-chamber volume. The
exhaust gas exergy of Model-1.3% and Model-2.1% are the lowest values,
approximately 29% of the fuel exergy. Increasing the volume of the pre-chamber
from 1.3% of compression volume led to a reduction in emissions. An increase in
the pre-chamber volume increases the exit velocity of gases from the pre-chamber
bores, and turbulence in the entrance, exit, and inside the bores, which
generates uniform and isothermal heat across the cylinder. Therefore, a
pre-chamber with a compression volume below 5% stabilizes the combustion. Under
stable working conditions, a pre-chamber volume can be defined such that the
spark ignition (SI) engine would have the highest energy and exergy efficiencies
with the lowest emission.

Published: May 2023

The present investigation has been conducted to study the tribological and
adhesion properties of X10CrNi18-8 austenitic stainless steel (ASTM 301)
coatings deposited on aluminum alloys such as AU4G by using the arc-spraying
process. These coatings were made with and without a bond-coat layer, which is
constituted by NiAl. The structure of the phases that are present in coatings
was characterized by X-ray diffraction (XRD) and scanning electron microscopy
(SEM). The measurements of microhardness and tribological behavior at different
loads were also performed on the surface of the coatings. Adherence test was
also carried out using four-point bending tests. The SEM showed that the dense
microstructures of coatings have a homogeneous lamellar morphology with the
presence of porosities and unmelted particles. The main phase of coating
corresponds to a solid solution as a face-centered cubic (fcc). The
microhardness of coatings is nearly four times that of the two substrates of
aluminum alloys. The four-point bending test results showed that the NiAl bond
layer increases the critical interfacial fracture energy G
IC, the force to share the multilayer is more important.
Analysis and Optimization of Automotive Self-Priming Door Lock
Closing Sound
Authors: Zhang Yan , Hou Hangsheng , Yang Yusheng , Feng Jingting , Zhang Zhi
Published: May 2023

With higher customer expectations and advances in vehicular technology,
automotive functions and operations are becoming more intelligent. Electric
self-priming door locks fulfil the automatic closing and locking of side doors,
hatchback doors, sliding doors, liftgates, decklids, etc. They are widely
implemented into high-end models for the elegance of soft closing. In the list
of perceived vehicle qualities, door-closing sound quality has been one of the
important customer concerns in the market. In comparison to conventional door
locks, electric self-priming door locks add another dimension to the development
of sound quality for noise, vibration, and harshness (NVH) efforts. In this
article, the characteristics of door-closing sound involving self-priming door
lock mechanisms are analyzed and illustrated. Human perception of different
sounds from the self-priming door lock working process is ranked by subjective
evaluations. For typical door closing sounds associated with the self-priming
lock mechanisms, i.e., the motor sound and rebound sound, real-case examples are
discussed. A case of the buzzing noise issue due to the self-priming lock on a
hatchback door is also presented. In these cases, the correlation between the
sounds and the structure of the self-priming door locks is investigated and the
root causes of the encountered issues are identified. The door closing sound
quality associated with the self-priming door locks is improved in each case to
meet the program requirements. In the particular cases presented in this work,
the analysis involves psychoacoustic metrics for sound quality study originally.
It is found later that sound pressure level can address the encountered issues,
and thus only sound pressure level results are included.
Localization in Global Positioning System–Denied Environments Using
Infrastructure-Embedded Analog-Digital Information
Authors: Moosavi Samin , Weaver Andrew , Gopalswamy Swaminathan
Published: May 2023

While a majority of transportation and mobility solutions rely on in-vehicle
sensors and the availability of the global positioning system (GPS) for absolute
localization, alternate paradigms leveraging smart infrastructure have started
becoming a viable solution for localization without needing GPS. However, the
majority of approaches involving smart infrastructure require a means for
wireless communication. In this article, we describe a novel method that can
accurately localize the vehicle without using GPS and wireless communication by
leveraging embedded digital and analog information on the roadside signage. The
embedded information consists of a digital signature which can be used to
cross-reference the ground truth (GT) location of the signage, as well as
geometric information of the signage. This information is directly leveraged by
on-vehicle sensors to generate absolute localization information. Specifically,
the smart infrastructure consists of signage that is visible primarily in the
infrared (IR) spectrum. A specialized camera that is optimized to read the
digital signature extracts the analog information associated with the signage
(ground truth and geometry). This is then used by both the camera, as well as a
millimeter (mm)-wave radar to produce independent localization information. The
camera and radar information are correlated with the signage information using a
global nearest neighbor algorithm, followed by fusion with vehicle odometry
using an extended Kalman filter (EKF) to generate accurate localization of the
vehicle. The EKF is set up to manage asynchronous observations between the
camera, radar, and vehicle odometry. The proposed method is implemented to
localize a vehicle without the aid of GPS, and the results show consistent
localization with the root mean squared (RMS) longitudinal and lateral errors
less than 0.46 m and 0.19 m, respectively.
A Multiagency Long Short-Term Model Beamforming Prediction Model for
Cellular Vehicle to Everything
Authors: Elangovan Vivekanandh , Xiang Weidong , Liu Sheng
Published: May 2023

Machine learning (ML) for predicting wireless channels of vehicular
communications networks has attracted interest in recent years. Beamforming is a
technique used to selectively transmit and receive data in a desired direction.
The receiver should be capable of choosing the right beam at the right time. The
usage of adaptive antenna scanning, i.e., scanning all the beams and choosing
the best beam will result only in 30% accuracy, which means 70% of the data will
be lost. This article studied a multiagency long short-term memory (LSTM)
beamforming prediction model based on signal strength to forecast optimum beams
within each beacon interval (BI) for cellular vehicle-to-everything (C-V2X)
systems. The model combines the outputs of several parallel prediction models
resulting in an enhanced accuracy of prediction. Simulation data validated the
effectiveness of the proposed prediction model on the university campus,
resulting in a 24% improvement in prediction accuracy.
Effect of Fast Charging on Lithium-Ion Batteries: A
Review
Authors: Abd El Baset Abd El Halim Ahmed , Bayoumi Ehab Hassan Eid , El-Khattam Walid , Ibrahim Amr Mohamed
Published: May 2023

In recent years we have seen a dramatic shift toward the use of lithium-ion
batteries (LIB) in a variety of applications, including portable electronics,
electric vehicles (EVs), and grid storage. Even though more and more car
companies are making electric models, people still worry about how far the
batteries will go and how long it will take to charge them. It is common
knowledge that the high currents that are necessary to quicken the charging
process also lower the energy efficiency of the battery and cause it to lose
capacity and power more quickly. We need an understanding of atoms and systems
to better comprehend fast charging (FC) and enhance its effectiveness. These
difficulties are discussed in detail in this work, which examines the literature
on physical phenomena limiting battery charging speeds as well as the
degradation mechanisms that typically occur while charging at high currents.
Special consideration is given to charging at low temperatures. The consequences
for safety are investigated, including the possible impact that rapid charging
could have on the characteristics of thermal runaway (TR). In conclusion,
knowledge gaps are analyzed, and recommendations are made as regards the path
that subsequent studies should take. Furthermore, there is a need to give more
attention to creating dependable onboard methods for detecting lithium plating
(LP) and mechanical damage. It has been observed that robust charge optimization
processes based on models are required to ensure faster charging in any
environment. Thermal management strategies to both cool batteries while these
are being charged and heat them up when these are cold are important, and a lot
of attention is paid to methods that can do both quickly and well.
Modelling of Polymer Suction Tube through Simulations
Authors: NALE ANIKET ARUN , Maurya Rohit K , Soma Nagaraju , Mohammed Zubair
Published: May 2023

The oil is picked up from the oil sump and transferred to the pump housing via a suction tube at the desired rate. A strainer is fitted to the end of the suction tube to filter out any dust or debris that may be present. Steel tubes and wire mesh strainers are used to make the current suction tube. Suction tube design shouldn't have an excessively long inlet suction that would make the suction tube's pressure insufficient to suck the oil from sump. Additionally, the pump's suction side air leak or low temperature-induced low oil viscosity prevents the pump from priming. This paper will examine suction tube design analysis and compared the development of steel and polymer suction tube concepts. The lightweight polymer suction tube with respect to fluid dynamics aspects is compared with conventional wire mesh. Extreme temperature analysis of polymer suction tubes will be compared to baseline steel tubes for suction flow, the impact of mesh area, pressure drop, and temperature parameters, and findings will be presented. The flow performance of polymer suction tubes was found to be substantially above that of steel wire mesh suction tubes. Due to the decreased opening area of an all-polymer suction tube, the average pressure drop is larger, and pressure decreases in the suction tube have an impact on the pump's filling speed. Compared to steel suction tubes, polymer suction tubes are lighter and cheaper, easier to manufacture, need fewer parts, and have higher reliability.

Authors: Ndung’u Catherine Waithera , Ntabo Victor Ondara
Published: May 2023

Proverbial metaphors are useful resources for communicating known truths about life in a given community. Most African proverbial metaphors, however, make reference to customs and situations that might be unfamiliar to some language users especially young people. On the basis of this background, this study employed image schemas to interpret Ekegusii proverbial metaphors that allude to young people. The research was anchored within descriptive research design. Primary data was collected from four Ekegusii respondents of an advanced age of at least seventy years old through an interview schedule. The collected data were then subjected to the Metaphor Identification Procedure Vrije Universiteit (MIPVU) in which four annotators were used to identify Ekegusii proverbial metaphors. Seven Ekegusii proverbial metaphors that refer to young people were identified through MIPVU. The identified proverbial metaphors were then subjected to the FORCE and CONTAINER schemas and their subsidiary schemas for analysis. The paper reveals that there are norms and customs regarding young people that are conveyed through Ekegusii proverbial metaphors. In addition, image schemas are fundamental in explaining the role, place, and cultural expectations of young men and women in Gusii. The study concludes that proverbial metaphors are useful tools of communication, and should be interpreted using Cognitive Linguistics paradigm.

Curated eLearning in South Africa: A user burgeoning perspective
Authors: Goosen Wynand
Published: May 2023

Purpose: This investigates the role of curation as an agile way of improving learner experience in eLearning. The current eLearning systems in South Africa often fail to provide effective learning experiences due to their one-size-fits-all approach, such as the assumption that eLearning can replace the educator's role. The absence of a “support process” for eLearning hampers effective learning. The current Digital Eco System focuses on eLearning with limited regard for learner contexts.

Methodology: The International Youth Foundation (IYF) “curated” a program consisting of a Google Certificate, Critical Thinking, and Life Skills called “Skills for Success” (S4S).  The curated program was completed by 500 learners. A survey of the learners was conducted to interpret user experience. A literature review, including journals, conferences, books, and websites, supports the research survey. The researcher’s experience and observations are also documented. Concepts and Categories are identified from where “themes” are identified. Findings are made using grounded theory.

Findings: The grounded theory process indicates that the learning landscape requires a “Curated Learning System”. Process curation includes WhatsApp, Email, Telephonic Support, Zoom, Teams, and SMS, whilst content curation includes Critical-Thinking, Passport-to-Success and a Google Certificate, all delivered in one program called “Skills for Life”. The “curation” of eLearning consists of “process” as well as “content” for more effective programs. Traditional support from facilitators is required in a non-traditional format. The research is confined to the “curation” of learning that is delivered online. Quality of Learner Management and online eLearning systems are excluded.

Recommendations: From the themes, the research supports the role of content and process-curated learning, a need for more agility in eLearning delivery, and the importance of having a Home Space, a Work Space, and a “Third Space” where effective learning can occur. The research also shows how technology drives the development of a Digital Framework for delivering effective learning programs and the evolution of Homo Digitalis.
Факторы дивидендной политики российских компаний
Authors: Долгих С.И. , Потанин Б.С.
Published: May 2023

В статье исследуются детерминанты дивидендной политики российских компаний. Дивидендная политика рассматривается как последовательное принятие двух решений: о выплате дивидендов и об их величине. Для оценивания влияния различных факторов на оба этих решения предлагается полупараметрическая двухшаговая процедура оценивания моделей с неслучайным отбором, объединяющая преимущества подходов Ньюи и Ли. Предложенная процедура продемонстрировала преимущество перед классическими подходами и позволила оценить влияние возраста, размера, рентабельности, формы собственности и доли основных средств в активах фирм, как на вероятность, так и на объем дивидендных выплат.
Трансформация и сохранение потенциала развития экономики России
Authors: Комков Н.И.
Published: May 2023

Рассматриваются проблемы развития отечественной экономики на этапе ее перемещения от стабильной, но ограниченной в возможностях использования своего потенциала ситуации к состоянию неопределенности и необходимости реагирования на новые глобальные вызовы. Россия располагает развитым военным, промышленным, кадровым и др. потенциалом. В то же время неотложность преодоления последствий многосторонних санкций, воздействующих на промышленное и технологическое развитие России, смещает достижение национальных целей на некоторый срок, но не меняет необходимости концентрации развития на инновационно-технологической основе.

Оценка состояния экономической безопасности региональных интеграционных объединений на примере Евразийского экономического союза
Authors: Пак А.Ю. , Андронова И.В.
Published: May 2023

В статье на основе исследования методологических представлений об оценке состояния экономической безопасности государства разработана система показателей экономической безопасности регионального интеграционного объединения. Указанная система включает три группы показателей – оценки качества жизни населения, внешнеторгового взаимодействия и конкурентоспособности, промышленного производства и кооперации. На основе разработанной системы показателей изучено состояние экономической безопасности Евразийского экономического союза и сделаны выводы о соответствии или несоответствии отдельных показателей установленным пороговым значениям. В частности, отмечено, что показатели, характеризующие количественное и качественное участие Евразийского экономического союза (ЕАЭС) в мировой торговле инновационной промышленной продукцией, имеют очень низкие значения. Несмотря на проводимую правительствами государств-членов интеграционного объединения промышленную политику, направленную на развитие инновационного высокотехнологичного промышленного производства в обрабатывающих секторах, в этом отношении явно прослеживается проблема высокой степени зависимости от импорта третьих стран. Приведенные в статье данные свидетельствуют о том, что ни по одной из трех групп показателей состояние экономической безопасности ЕАЭС не обеспечивается. Особенно обостряется ситуация в части состояния развития обрабатывающей промышленности ЕАЭС и использования потенциала внутреннего рынка.

Daily Stock Price Prediction: A Case Study in Vietnam
Authors: Chieu Ta Quang , Hang Vu Thi Kim
Published: May 2023

Stock price prediction remains a topic of debate. The Efficient Market Hypothesis argues against the need for prediction, stating that markets already incorporate all relevant information. However, the emergence of Deep Learning in Machine Learning has led many to believe in the potential of sophisticated algorithms in uncertain and volatile stock markets. The outcome of this debate varies based on market characteristics. To analyse this discussion within the framework of emerging market like Vietnam, a study examines nine stocks listed on the Ho Chi Minh Stock Exchange (HOSE). Time-series data is visualized and analysed to test various hypotheses. Three algorithms Linear Regression, SARIMA, and LSTM are researched and applied to predict stock prices. The predictions are compared and benchmarked against the Naive approach. The study concludes that the Linear approach outperforms Deep Learning. This difference may be attributed to the characteristics of the emerging market, such as its young age, low regulation, and high volatility with outliers. Traditional Machine Learning and Deep Learning both surpass the Naive approach, rejecting the Efficient Market Hypothesis in Vietnam.
