Systems Evaluation of Subsonic Hybrid-Electric Propulsion Concepts for NASA N+3 Goals and Conceptual Aircraft Sizing
Authors: Jagtap S. S. 
Published: December 2019

The air-travel demand is anticipated to grow in future and therefore the worldwide airtraffic is forecast to increase significantly. This growth in demand further increases the concerns pertaining to environmental and human health, which results in stringent aviation policies. Emission regulations have been set for the aviation sector to reduce its climate change impacts, and these support the efforts to meet the goals of the UN’s Paris treaty on climate change. The aviation sector is exploring sustainable and improved technologies to become more energy and cost efficient. Along these lines, NASA has developed the concept of ‘N+i’ goals to decrease fuel consumption, noise, and landing and take-off (LTO) oxides of nitrogen (NOx) emissions, and to enhance aircraft performance. The ‘N+3’ represents three technology generations into the future, where ‘N’ represents the current aircraft generation, with a forecasted technology readiness level 4-6, in year 2025 timeframe which will enable year 2035 service-entry. To meet NASA’s N+3 goals, significant improvements must be made in the air transportation system, airframe, mission design, and propulsion systems. A pivotal element to achieve these goals, is the propulsion system. This is because the role of propulsion system can be crucial in reducing emissions, noise, and fuel burn. This work evaluates the N+3 concepts in detail, based on the systems engineering approaches and selects the best of those concepts. A detailed analysis is presented for phase one of such a project using Georgia Institute of Technology’s Integrated Product-Process Development (IPPD) method. This work finds that the NASA N3-X turbo-electric distributed propulsion (TeDP) is the best concept for meeting the NASA N+3 goals, based on the systems engineering approach.

Authors: Bale J. 
Published: December 2019

In many applications of composites, open-hole frequently includes for various purposes. However, further study on open-hole behaviour is still required, including on its strength and damage properties by combining experimental testing, real-time observations and calculations based on theoretical analysis and simulation model. The objective of this study is to understand the effect of an open-hole glass fibre reinforced polymer (GFRP) composites on tensile (static) properties, damage behaviour through Non-destructive Testing (NDT) Thermography and stress concentration factor (SCF). This study used an open-hole rectangular of GFRP specimens that fabricated by filament winding (FW) method and resin transfer moulding (RTM) method. It is found that the RTM specimens generate ≈ 170 % higher of tensile strength and ≈ 100 % higher of tensile modulus compared to the FW specimens. Infra-red (IR) camera shown the good detection on damage behaviour based on temperature increase at elastic and failure phase. Moreover, theoretical analysis and simulation results shown the good correlation where SCF reaches more than 4 times at the edge of the hole. This study concludes that open-hole on GFRP composites affects the tensile properties and generates damage marked by temperature increase and high SCF at the edge of the hole.

Published: December 2019

Natural convection within trapezoidal enclosures finds significant practical applications. The natural convection flows play a prominent role in the transport of energy in energyrelated applications, in case of proper design of enclosures to achieve higher heat transfer rates. In the present study, a two-dimensional cavity with adiabatic right side wall is studied. The left side vertical wall is maintained at the constant hot temperature and the top slat wall is maintained at cold temperature. The dimensionless governing partial differential equations for vorticity-stream function are solved using the finite difference method with incremental time steps. The parametric study involves a wide range of Rayleigh number, Ra, 103 ≤ Ra ≤ 105 and Prandtl number (Pr = 0.025, 0.71 and 10). The fluid flow within the enclosure is formed with different shapes for different Pr values. The flow rate is increased by enhancing the Rayleigh number (Ra = 104 ). The numerical results are validated with previous results. The governing parameters in the present article, namely Rayleigh number and Prandtl number on flow patterns, isotherms as well as local Nusselt number are reported.

Published: December 2019

Unmanned aerial vehicles (UAVs) have gained a lot of attention in recent times due to its versatility in deployment for multifaceted operations. The development of amphibious UAVs with inculcating the features of hovercraft and multi-rotor has tremendous impact on military, naval and coastal guard applications. Stability and performance of this kind of vehicle highly depend on aerodynamic interaction of multirotor with respect to various wind conditions. The present study focuses on performing computational fluid dynamic (CFD) analysis on examining the vortex formation, turbulent regimes, wake region, tip vortex formulation and ground effect.Preliminary flow analysis is performed to determine the angle of attack (AoA) and wind speed on which minimal drag is experienced by the amphibious structure. Further, analysis conducted through varying the relative velocity of the vehicle and changing the speed of the propellers. The pressure distribution across the fuselage and rotor surface predicted the stability of the vehicle. The ground effect is examined through varying the clearance between the vehicle and ground surface with respect to a multiplicity of rotor diameter. CFD analysis results suggested that at 5° AoA and 8.3 m/sec the designed amphibious vehicle yielded superior performance characteristics and stability.

Published: December 2019

Abstract. The difference and plurality of interpretations of the Qur'an is a fact that cannot be denied. Nevertheless, in an interpreting community always shows a uniqueness that draws a line of difference from other interpreting communities. This article discusses the orthodoxy of interpretations that developed widely in the Sunni tradition by adopting and modifying the orthodoxy concept developed by David C. Martin, Abbas Barzegar and Norman Calder, then to be investigated through al-Ittijahat al-Munharifah fi Tafsir al-Qur'an: Dawa fi’uha wa Daf’uha by Muhammad Husein al-Dzahabi. This paper shows that the orthodoxy of Sunni interpretation is built on three fundamental structures; textual orientation, recognition of the authority of previous generations, and theological identification of Sunni groups. Abstrak. Perbedaan dan pluralitas penafsiran terhadap al-Qur’an merupakan sebuah fakta yang tidak bisa dipungkiri. Kendati demikian, dalam sebuah komunitas penafsiran selalu menunjukkan keunikan yang menarik garis perbedaan dari komunitas penafsiran yang lain. Artikel ini membahas tentang ortodoksi tafsir yang berkembang secara luas dalam tradisi Sunni dengan mengadopsi dan memodifikasi konsep ortodoksi yang dikembangkan oleh David C. Martin, Abbas Barzegar dan Norman Calder untuk kemudian diuji melalui buku al-Ittijahat al-Munharifah fi Tafsir al-Qur’an: Dawafi’uha wa Daf’uha karya Muhammad Husein al-Dzahabi. Tulisan ini menunjukkan bahwa ortodoksi tafsir Sunni dibangun di atas tiga struktur mendasar; orientasi tekstual, pengakuan terhadap otoritas generasi terdahulu, serta identifikasi teologis kelompok Sunni.
IMPLEMENTASI PESAN MORAL MISI PROFETIK MUHAMMAD MENURUT FAZLUR RAHMAN
Authors: Hakim Lukman , Ramdani Dani 
Published: December 2019

Abstract. Muhammad's prophetic mission is a mission in an effort to disseminate moral teachings whose roots are found in the teachings of monotheism, as is often emphasized in the Qur'an: efforts to uphold social justice, egalitarianism and protection of the weak. Rahman offers a hermeneutic method to refine the Qur'an and criticize the historical awareness that exists in Muslims. This is done to provide the right meaning for the Qur'an, as well as examine the awareness of the religious traditions of Muslims today. Then Rahman offered the double movement method. This method will be very useful for examining all forms of religious institutionalization established by Muslims today, then confirming it to the time of the Prophet to obtain legitimacy or appropriate reference to religious interpretations. Double movement, intended to provide the right meaning for Muslim efforts to interpret religion based on traditions established by the Prophet: refers to the initial conception that was built by the Prophet and his companions. Abstrak. Misi profetik Muhammad merupakan suatu misi dalam upaya menyebar-luaskan ajaran moral yang muaranya terdapat dalam ajaran monoteisme, sebagaimana yang sering ditegaskan dalam al-Qur’ân: usaha untuk menegakkan keadilan sosial, egaliterianisme dan perlindungan terhadap yang lemah. Rahman menawarkan metode hermeneutika untuk menfasirkan kembali al-Qur’ân dan mengkritisi kesadaran sejarah yang ada dalam umat Islam. Hal ini dilakukan untuk memberikan makna yang tepat bagi al-Qur’ân, sekaligus memeriksa kesadaran tradisi keberagamaan umat Islam masa kini. Kemudian Rahman menawarkan metode double movement. Metode ini akan sangat berguna untuk memeriksa segala bentuk institusionalisasi keberagamaan yang dibangun oleh umat Islam di masa kini, kemudian mengkonfirmasikannya ke masa Nabi untuk mendapatkan legitimasi atau rujukan yang tepat terhadap interpretasi keberagamaan. Double movement, dimaksudkan untuk memberikan makna yang tepat bagi usaha umat Islam untuk melakukan interpretasi keberagamaan berdasarkan tradisi yang dibangun oleh Nabi: merujuk kepada konsepsi awal yang telah dibangun oleh Nabi beserta para sahabatnya.

Published: December 2019

Abstract. Interfaith dialogue is a form of discussion and information exchange between the devotees of different religions, while da’wah is a form of preaching to Islam. In the context of opportunity, Muslims should accept the challenge of participation in interfaith dialogue. So thus preparation and knowledge about da’wah and interreligious dialogue has become a necessity before involving in interfaith dialogue. Based on the nature of inter-religious dialogue that emphasizes on openness, willingness to listen to different views and based on knowledge, then this method should be taken seriously by the Muslim in the context of contemperory da’wah to propagate Islam to the masses. Finally this paper concluded interfaith dialogue in Malaysia has a great potential and in the growing interest among the Muslim community in particular. Abstrak. Dialog antaragama adalah bentuk diskusi dan pertukaran informasi antara para pemeluk agama yang berbeda, sementara dakwah adalah bentuk dakwah kepada Islam. Dalam konteks kesempatan, umat Islam harus menerima tantangan partisipasi dalam dialog antaragama. Jadi persiapan dan pengetahuan dakwah dan dialog antaragama telah menjadi kebutuhan sebelum terlibat dalam dialog antaragama. Berdasarkan pada sifat dialog antar agama yang menekankan pada keterbukaan, kesediaan untuk mendengarkan pandangan yang berbeda dan berdasarkan pada pengetahuan, maka metode ini harus ditanggapi dengan serius oleh Muslim dalam konteks kontekstualisasi dakwah untuk menyebarkan Islam kepada massa. Akhirnya makalah ini menyimpulkan dialog antaragama di Malaysia memiliki potensi besar dan dalam minat yang tumbuh di kalangan komunitas Muslim pada khususnya.
Functional neural changes and altered cortical–subcortical connectivity associated with recovery from Internet gaming disorder
Authors: Dong Guang-Heng , Wang Min , Zhang Jialin , Du Xiaoxia , Potenza Marc N. 
Published: December 2019

Background and aims
Although studies have suggested that individuals with Internet gaming disorder (IGD) may have impairments in cognitive functioning, the nature of the relationship is unclear given that the information is typically derived from cross-sectional studies.

Methods
Individuals with active IGD (n = 154) and those individuals no longer meeting criteria (n = 29) after 1 year were examined longitudinally using functional magnetic resonance imaging during performance of cue-craving tasks. Subjective responses and neural correlates were contrasted at study onset and at 1 year.

Results
Subjects’ craving responses to gaming cues decreased significantly at 1 year relative to study onset. Decreased brain responses in the anterior cingulate cortex (ACC) and lentiform nucleus were observed at 1 year relative to onset. Significant positive correlations were observed between changes in brain activities in the lentiform nucleus and changes in self-reported cravings. Dynamic causal modeling analysis showed increased ACC–lentiform connectivity at 1 year relative to study onset.

Conclusions
After recovery from IGD, individuals appear less sensitive to gaming cues. This recovery may involve increased ACC-related control over lentiform-related motivations in the control over cravings. The extent to which cortical control over subcortical motivations may be targeted in treatments for IGD should be examined further.

Connecting Performance and Performing Connection: How the Performing Arts Can Usefully Engage an International and Interdisciplinary Cohort in Pedagogy and Research
Authors: Harley Anne 
Published: December 2019

This article draws upon my experiences from the last several years (2014–2017) of leading collaborative performing arts projects with students and faculty from US liberal arts colleges and Asian partner institutions. Herein, I describe how the performing arts, like other forms of embodied learning, can usefully function to convene students and faculty who operate in different disciplines and languages. The performing arts could be more central to and useful in education about and engagement with environmental issues by enlisting embodied learning, memory skills, transdisciplinarity, social networks, emotion, and liminal spaces of imaginative vision. The performing arts offer powerful tools for constructing international and interdisciplinary collaborations and exchanges. Applied voice study in the liberal arts context also offers help in lowering language barriers in intercultural exchanges. Included are brief descriptions of performing arts projects which helped cement collaborative relationships in past projects. An epilogue follows, describing how development of a performance can also be a form of cultural research in and of itself, using Augusto Boal’s (1985) model of ‘participatory action research.’

Comparative Analysis of the Feature Extraction Performance of Augmented Reality Algorithms
Authors: TOSUN Umut 
Published: December 2019

The algorithms that extract keypoints
and descriptors in augmented reality applications are getting more and more
important in terms of performance.
Criterions like time and correct matching of points gain more impact according
to the type of application. In this paper, the performance of the algorithms
used to identify an image using keypoint and descriptor extraction is studied. In the context of this research,
main criterion like the number of keypoints and descriptors that the algorithms
extract, algorithm execution time, and the quality of keypoints and descriptors
extracted are considered as the performance metrics. Same data stacks were used
for obtaining comparison results. In addition to comparisons for a group of
well-known augmented reality applications, the best performing algorithms for
varying applications were also suggested. C++ language and OpenCV library were
used for the implementation of the augmented reality algorithms compared.
Energy loss analysis from RBS spectrum of thin Cu2ZnSnS4 (CZTS) film
Authors: USTA Metin 
Published: December 2019

The goal of this work is to
offer an alternative method to the available literature on determining the
energy loss of CZTS thin films. For this purpose, thin CZTS film structures
were first produced by sol-gel method and then the RBS spectrum was received
with RBS detector irradiating this structure with 3.034 MeV proton beams in a
microbeam chamber. The energy calibration was implemented to this spectrum,
where the it was fitted with SIMNRA program. In the RBS spectrum of the thin
film generated, a method for the calculation of energy loss was used for the
position and energy width analysis of the corresponding peaks and a polynomial
fit was obtained from the stopping power of the CZTS thin film by making
certain approaches. Also, the effective charge approach that we used in our
previous studies for the stopping power was employed with atomic natural
orbitals and it was founded that the results were close to each other at
certain error rates. The data obtained
from this study will inspire the future studies on the interaction of radiation
with matter.
