Published: June 2021

Construction of civil engineering structures on weak soil without taking necessary precautions may be risky. Alluvial soil that has not completed its geological formation has a high void ratio and contains organic material therefore, the strength properties of these soils should be examined carefully. In this study, the undrained shear strength (cu) behavior of natural and polypropylene (PP) fiber-reinforced alluvial clays was investigated with a laboratory Vane shear test. To examine the moisture content effects on cu behavior of alluvial clay, samples were prepared in 0.50 liquid limit (LL), 0.75 LL, and LL water contents. The PP fibers used were 6 and 18 mm long, they mixed with soil 0.1, 0.5, and 1% by dry weight of the sample. The Vane shear tests were performed at two different depths to investigate the overburden pressure effect. The increase in water content caused a significant decrease in cu. The laboratory results indicated that the cu of PP reinforced (1 % and 18 mm PP) alluvial clay deposits prepared in 0.5LL, 0.75LL, and LL water contents were 56.6, 20.7, and 8.4 kPa, respectively. The increase in PP fiber content increased the cu of alluvial clay deposits. The length of fiber was directly proportional to cu values. The effect of fiber was more pronounced in long fiber added samples. The cu of natural and %1 fiber reinforced (6 mm and 18 mm) samples prepared in the same water content were 27.4, 29.1, and 55.7 kPa. The cu increased with increasing penetration depth.

Direct Taxes and Income Redistribution in Nigeria
Authors: Ikechukwu OKOH Francis , Christopher EDO Onome , Justice AKHIGBODEMHE Emmanuel , Osaremen EDEOGHON Innocent
Published: June 2021

Introduction - Income redistribution is central to the development of any nation. However, the issue of generating income and its redistribution in Nigeria has been challenging overtime, with the nation depending largely on oil with little consideration on other sources of income. Also, insufficient tax resources, tax collectors' illicit activities and a lack of awareness of the value of paying tax by taxpayers are some of the problems facing the country in terms of tax revenue generation. Objective - Our study therefore investigated the impact of direct taxes on income redistribution in the context of Nigeria, using company income tax, personal income tax, petroleum profit tax and education tax as direct tax variables. Methodology/Technique - The study covered the period 1990 to 2019 using annualized data set from Federal Inland Revenue Service (FIRS) and Central Bank of Nigeria Statistical Bulletin. The study employed the Fully Modified Least Squares (FMOLS) to analyze the data. Research Findings - Empirical results of our study revealed that, company income tax and education tax had insignificant negative effects on income redistribution, while personal income tax and petroleum profit tax had significant positive effects on income redistribution, thus reducing income inequality in the context of Nigeria. Recommendations - We thus recommended "inter alia" that, revenue generated from taxes should be effectively used by government in providing quality infrastructures like schools, railway, healthcare facilities and other business outfits across various states for the general wellbeing of the citizens as this is hoped to close the income distribution gap between the rich and the less privileged in the country.

Published: June 2021

In this proposal new trapezoidal patch microstrip feed
antenna array with ground defected by square shape is designed
for detailed antenna parameter study in terms of return loss,
VSWR, gain and radiation pattern for S band applications from 2
to 3 GHz. The bandwidth and radiation properties of four
radiating element arranged in 2 x 2 array has been improved by
defecting half of the ground by etching square shape opposite to
the vertical feed point. 30 x 70 x 1.6 mm dimension structure has
been fabricated in FR4 substrate for low cost applications and
performance analyzed in three different planes. With comparison
of four element array with full ground, the proposed array with
defected ground has proved the improvement in behavior with
return loss of -34.687 dB and ideally fit with VSWR of 1.038.
Parametric study with feed length and substrate thickness has also
been performed optimized decision of structure dimension. This
study reveals that by reducing the substrate thickness and
increasing the feed length, we can improve the performance of
loss reduction. The front view has been simulated with full ground
and defected ground for comparison and the compared results
shows that the loss reduction of -22 dB has been achieved with
VSWR value of 1.03 from 2.28 for defected ground structure. The
designed structure has been simulated with CST software and the
comparison of simulated results has conform that the proposed
structure can be used for S band application like airport
surveillance radars with wide bandwidth of 120 MHz and gain of
3.52 dBi. Comparison has been made between the proposed
antenna array and the antennas available in literature with
respect to bandwidth gain, reflection coefficient and defection type
for better understanding.

Authors: Saxena Aditya , Gupta Vallary , Shrivastava Bhavna
Published: June 2021

Good connectivity and accessibility ensure inclusivity of public transport system which is an indicator of a fair society. The modal shift of commuters towards public transit services depends majorly on its accessibility levels. To ensure that commuters have equal opportunities to access jobs, education, and other services, PTAL (public transit accessibility level) is often evaluated. Public transport accessibility levels are a detailed and an accurate measure of accessibility of a point to the public transport network which considers walk access time and service availability. Public transportation is often referred to as an affordable model for every section of society due to its cheap fare price. The major question lies in the inclusivity of public transit services for the economically weaker section of society whether or not public transportation is available and accessible for those who need it or those who cannot afford other mobility services. The present study intends to focus on affordable and inclusive transportation for economically weaker sections. The study is an attempt to assess the issues with public transport services in the city of Bhopal, India for economically backward areas like slums. The research will help in understanding the accessibility level of currently available public transit services by evaluating the PTAL (public transit accessibility level) for socially backward.
A Novel Spectrum Decision Pattern for The Favorable Cognitive Radio Based Internet of Things in 5G System
Authors: A Hyils Sharon Magdalene. , Punithavathani D. Shalini
Published: June 2021

The Radio Frequency (RF) Spectrum decision in
Cognitive Radio (CR) allows unlicensed users of wireless
communication schemes to conquer the unoccupied spectrum
slots as a resolution for barely spectrum. The Internet of Things
(IoT) is a broad-arriving network and its object is linked by
wireless communication technologies, donating cost- efficiency
and generously opens to remote users. When IoT is applied, it is
injured by challenges of susceptibility in the forceful surrounding
situations, allotment and use of bandwidth, ease of approach and
expense to buy RF spectrum. The object is permeated with
cognitive capacity and is capable to model RF spectrum decisions
to attain interference-release and wireless connectivity due to their
Quality of Service (QoS) demands. Therefore the spectrum
decision through an unlicensed user on CR influences an
importance in CR-based IoT in 5G system and further network.
This article depicts a systematic sustainment of the spectrum
decision structure to CR Network. So, this can be mainly achieved
by applying a favorable spectrum sensing technique and a novel
spectrum decision framework. Presently, the wireless connectivity
is intended to greater capacity, immense machine connectivity,
and greater data range, low end-to-end latency, low cost and
coherent Quality of Experience (QoE) condition. Hence, 4G is
being substituted by 5G. Being in this 5G, the vast connectivity can
be properly inspired by using the novel techniques, which is
applied under the Energy detection spectrum sensing system. Also,
a novel spectrum decision framework is designed for the optimum
application of applying the IoT in 5G system ie., the effective use
of an allocated RF spectrum is differently underutilized because
of the standard handling with the licensed users are called as
Primary Users (PUs).

Authors: Soman Anetha Mary , Nakkeeran R , John Shinu Mathew
Published: June 2021

An integration of Spatial Modulation with Orthogonal Frequency Division Multiplexing (SM OFDM) is a recently evolved transmission technique. In practical scenarios, channel estimation is significant for detecting transmitted data coherently. Impulse response based interpolation technique that provides channel frequency response estimate with reduction in noise error is proposed for comb type pilot based channel estimation of SM OFDM system along with 1D interpolation techniques under frequency selective channel. This scheme focus on carrying out smoothing and estimation in time domain and transforming output back to the frequency domain. BER performance is investigated for Rayleigh channel employing COST 207 project model on two test urban environments (Typical and Bad) for 4 and 16 QAM SM OFDM systems. Results show that the Least Square estimator with DFT interpolation performs finer compared to all one dimensional interpolation methods with less computational complexity by employing FFT algorithms.

Authors:   Georgian Technical University, Andriadze Giorgi , Gurtskaia Zviad ,   Georgian Technical University
Published: June 2021

Temperature is one of the parameters that affects development of embryos. Therefore, it is important to keep stability of temperature in the chambers of embryo-incubators. In modern incubators, some accuracy of temperature has been achieved, although fluctuations are not eliminated yet. The aim of this research was to improve temperature accuracy by reducing of fluctuations. In modern benchtop incubators, a heating element is switched on and automatically shuts off when the desired value is reached. The heating element continues to heat up to a certain temperature after switching off, and the reverse process takes place during cooling. Inappropriate temperature may adversely affect the embryo. To control temperature more precisely, a new principle with infrared sensor has been developed, where power to heater is supplied with different PWM duty cycles. As the results, much more stable temperature with less fluctuations were achieved in comparison to modern systems using thermocouples and thermistors.

Authors: Putta Tharani , Deconda Kaushik
Published: June 2021

BACKGROUND AND OBJECTIVE: Role of chest CT in diagnosis of corona virus disease 2019 (COVID-19) has
been controversial. The purpose of this study is to evaluate the diagnostic performance of chest CT when utilizing
COVID-19 Reporting and Data System (CO-RADS).
METHODOLOGY: Retrospective study including consecutive patients with positive SARS-CoV-2 RT-PCR test (initial or repeat test) and
chest CT done in our institute between June and September 2020. Spectrum of CT ndings, CO-RADS score and 25 point CT severity score
(CTSS) were recorded.
RESULTS: A total of 300 consecutive patients with SARS-CoV-2 infection were included in the analysis. Out of the 168 patients who
underwent CT prior to positive RT-PCR result, 125 (74.4%) had CO-RADS 3, 4 or 5 score on chest CT. 32 study patients (10.6%) had initial
negative RT-PCR of which 24 (75%) had CO-RADS 4 or 5 score. Of the total patients with CO-RADS 3 to 5 score (227), 20 (8.8%) had severe
lung involvement (CTSS 18-25), 83 (36.6%) had moderate lung involvement (CTSS 8-17) and 124 (54.6%) had mild lung involvement (CTSS
1-7). The mean CTSS was 7.9 with mean lobar score being higher in lower lobes (RLL=1.82, LLL=1.78) compared to the upper and middle lobes
(RUL=1.61, RML=1.19, LUL=1.53).
CONCLUSION:CT using CO-RADS scoring system has good diagnostic performance. In addition to assessing disease severity, it plays a vital
role in triage of patients with suspected COVID-19 especially when there is limited availability of SARS-CoV-2 RT-PCR tests, delay in RT-PCR
test results or in negative RT-PCR cases when there is high index of clinical suspicion.
Design of a Highly Miniaturized, Inherently Matched, Spherical Folded Dipole Antenna and Evaluation of its Quality Factor
Authors: Iyer Ashwin , Das Sanghamitro
Published: June 2021

A highly miniaturized three-dimensional spherical folded dipole antenna has been reported, for which inherent impedance matching is achieved with respect to a practical source impedance by employing a simple series-LC loading combination, thereby engineering its input impedance. In order to maximize its bandwidth, the miniaturized antenna employs a spherical helix structure as the folded arm that occupies the full volume of the corresponding Chu sphere. A bifilar (two folded arms) and a quadrifilar (four folded arms) helix loaded folded dipole antenna are designed, and full-wave simulations show that both the resulting antennas demonstrate excellent impedance matching when miniaturized by 85% in comparison to a resonant dipole operating at the same frequency. Despite the high degree of miniaturization, the resulting radiation efficiencies for the bifilar and quadrifilar antennas are found to be 87.1% and 90.6%, respectively. Furthermore, various quality-factor definitions are explored for the quadrifilar antenna, and it is observed that the resulting quality factor is around 1.83 (1.22) times that predicted by the Chu (Thal) lower bound.
Emulating Full Load Testing of Air-cooled Nanocrystalline IHT at Zero Power
Authors: Paul Arun
Published: June 2021

High-power high-frequency air-cooled induction heating transformers,
mostly used as current multiplier and isolation purposes, are custom designed. For
their reliable performance and long life, the thermal evaluation at rated load
is necessary. Creating an equivalent load as test facility for reliability
testing of such type of transformer is difficult. Characteristics of such loads
drastically change after Curie temperature. Moreover, prolonged heating could
increase the nearby ambient temperature and, more importantly, the traditional heat
run test wastes large amount of energy. Whenever the coil is energized, windings
of transformer draw respective rated current; even at no load condition the copper
loss is at rated value. While both windings drawing rated current at desired
frequency, using the concept of localized eddy current loss as well as excess eddy
current loss, this article proposes a novel method to inject requisite core
loss to the magnetic circuit to emulate the characteristics of full load condition
but the power drawn from the transformer would be zero. The proposed idea would
be validated where only 200 W resonant inverter would be used to inject power
loss equivalent to full-load condition of 30 kW transformer to emulate the heat
run test.
Deep Meta-Learning Energy-Aware Path Planner for Unmanned Ground Vehicles in Unknown Terrains
Authors: Visca Marco , Powell Roger , Gao Yang , Fallah Saber
Published: June 2021

This paper presents an adaptive energy-aware prediction and planning framework for vehicles navigating over terrains with varying and unknown properties. A novel feature of the method is the use of a deep meta-learning framework to learn a prior energy model, which can efficiently adapt to the local terrain conditions based on small quantities of exteroceptive and proprioceptive data. A meta-adaptive heuristic function is also proposed for the integration of the energy model into an A* path planner. The performance of the proposed approach is assessed in a 3D-body dynamic simulator over several typologies of deformable terrains, and compared with alternative machine learning solutions. We provide evidence of the advantages of the proposed method to adapt to unforeseen terrain conditions, thereby yielding more informed estimations and energy-efficient paths, when navigating on unknown terrains.

Reviewer Recommendations Using Document Vector Embeddings and a Publisher Database: Implementation and Evaluation
Authors: Zhao Yue , Anand Ajay , Sharma Gaurav
Published: June 2021

We develop and evaluate an automated data-driven framework for providing reviewer recommendations for submitted manuscripts. Given inputs comprising a set of manuscripts for review and a listing of a pool of prospective reviewers, our system uses a publisher database to extract papers authored by the reviewers from which a Paragraph Vector (doc2vec ) neural network model is learned and used to obtain vector space embeddings of documents. Similarities between embeddings of an individual reviewer’s papers and a manuscript are then used to compute manuscript-reviewer match scores and to generate a ranked list of recommended reviewers for each manuscript. Our mainline proposed system uses full text versions of the reviewers’ papers, which we demonstrate performs significantly better than models developed based on abstracts alone, which has been the predominant paradigm in prior work. Direct retrieval of reviewer’s manuscripts from a publisher database reduces reviewer burden, ensures up-to-date data, and eliminates the potential for misuse through data manipulation. We also propose a useful evaluation methodology that addresses hyperparameter selection and enables indirect comparisons with alternative approaches and on prior datasets. Finally, the work also contributes a large scale retrospective reviewer matching dataset and evaluation that we hope will be useful for further research in this field. Our system is quite effective; for the mainline approach, expert judges rated 38% of the recommendations as Very Relevant; 33% as Relevant; 24% as Slightly Relevant; and only 5% as Irrelevant.
Joint 3-D Positioning and Power Allocation for UAV Relay Aided by Geographic Information
Authors: Yi Pengfei , Zhu Liang , Zhu Lipeng , Xiao Zhenyu
Published: June 2021

In this paper, we study to employ geographic information to address the blockage problem of air-to-ground links between UAV and terrestrial nodes. In particular, a UAV relay is deployed to establish communication links from a ground base station to multiple ground users. To improve communication capacity, we fifirst model the blockage effect caused by buildings according to the three-dimensional (3-D) geographic information. Then, an optimization problem is formulated to maximize the minimum capacity among users by jointly optimizing the 3-D position and power allocation of the UAV relay, under the constraints of link capacity, maximum transmit power, and blockage. To solve this complex non-convex problem, a two-loop optimization framework is developed based on Lagrangian relaxation. The outer-loop aims to obtain proper Lagrangian multipliers to ensure the solution of the Lagrangian problem converge to the tightest upper bound on the original problem. The inner-loop solves the Lagrangian problem by applying the block coordinate descent (BCD) and successive convex approximation (SCA) techniques, where UAV 3-D positioning and power allocation are alternately optimized in each iteration. Simulation results confifirm that the proposed solution signifificantly outperforms two benchmark schemes and achieves a performance close to the upper bound on the UAV relay system.

Turismo e historiografía del saber: entre la historia del progreso y la emergencia de los olvidados
Authors: Comparato Gabriel Joaquín
Published: June 2021

El presente escrito se propone problematizar y analizar, en clave metahistórica,  el tratamiento que han tenido los estudios turísticos como objeto de estudio enfatizando en algunas particularidades latinoamericanas en el escenario de posguerra. Lejos de ser exhaustivo y excluyente, toma como punto de partida un área de vacancia de la literatura con una impronta reflexiva, en el que se combinan debates historiográficos generales y, a posteriori, discusiones más específicas del campo. En este sentido, se propone desarticular un tipo de hacer historia, cargada de continuidad y coherencia, para dar lugar, propedéuticamente, a sesgos, déficits y relaciones de poder. Específicamente, a partir de una revisión de la literatura, se identificó que dentro de los estudios turísticos históricos prevalece una tendencia a ser racionalista, gradualista y consensual, marcada por una narrativa con hegemonía occidentalizada y angloparlante, recurriendo a holgadas y estrechas fuentes historiográficas. Pero lejos de dar un cierre y pretender realizar una propuesta totalizadora, el trabajo apunta a la necesidad de profundizar los ejercicios de reflexividad disciplinar en lo relativo a la construcción, reconstrucción y deconstrucción de las narrativas históricas. Es una invitación más que un cierre y, en particular, a reflexionar no solo cognoscitivamente, sino también, y simultáneamente, en clave política.
