Zielone miasta w Polsce – analiza porównawcza na podstawie agregatowego miernika rozwoju
Authors: Antczak Elżbieta , Rzeńca Agnieszka , Sobol Agnieszka
Published: December 2023

Idea zielonego miasta ma na celu wpisanie uwarunkowań środowiskowych w fundamenty strategii jego rozwoju, budowanie równowagi przyrodniczej i odporności klimatycznej oraz stymulowanie zielonej transformacji terenów miejskich. Zazielenianie miast polega na wyborze priorytetów i działań zapewniających wysoki poziom jakości życia i ochronę środowiska oraz ograniczenie ryzyka i zagrożeń powodowanych przez zmiany klimatu. Celem badania omawianego w artykule jest ocena stopnia zazielenienia polskich miast na prawach powiatu. Analiza dotyczy wybranych lat: 2010, 2015, 2018 i 2020. Dane do analizy uzyskano m.in. z Głównego Urzędu Statystycznego, Urzędu Regulacji Energetyki, Głównego Urzędu Geodezji i Kartografii oraz z biuletynów informacji publicznej poszczególnych miast. Biorąc pod uwagę, że stan środowiska przyrodniczego polskich miast i powiązanych z nim sektorów gospodarki miejskiej jest bardzo zróżnicowany, postawiono dwa pytania badawcze: o skalę różnic w poziomie zazielenienia miast oraz o determinujące te różnice elementy środowiska czy procesy z nim związane. Skonstruowano syntetyczny miernik rozwoju, wykorzystując bezwzorcową metodę porządkowania liniowego w ujęciu dynamicznym. W tym celu wyznaczono uśrednioną wartość cech, które unormowano za pomocą metody unitaryzacji zerowanej. Poza uporządkowaniem miast pogrupowano je metodą kwartyli pod względem podobieństwa wartości miernika. Uzyskane wyniki wskazały na postęp w procesie zazieleniania miast na średnim poziomie, tj. ok. 2,5% rocznie. Widoczne jest duże zróżnicowanie między miastami, lecz można zaobserwować stopniową niwelację tych różnic. Pozwala to ostrożnie wnioskować o wyrównywaniu się poziomu rozwoju zielonych miast. Należy przy tym zauważyć, że monitoring zielonego miasta jest niezbędny do opracowania efektywnych polityk miejskich i strategii rozwoju odpowiadających na zmiany klimatu. Kluczowe jest zatem ujęcie w publicznych bazach danych mierników, które umożliwią ocenę procesu rozwoju z uwzględnieniem obszarów i kierunków rozwoju idei zielonego miasta.

Published: December 2023

The research on dry bulk terminal improvement is currently limited and lacks focus, despite the increasing global demand for dry bulk cargo. The primary aim of this paper is to propose a design for enhancing dry bulk terminal operations and identify a significant factor for improving dry bulk terminal performance through the utilization of the Quality Function Deployment (QFD) method. The fundamental concern in QFD pertains to determining the customer’s desires and formulating an effective strategy to address the identified challenges. These two elements are of utmost importance and are considered essential components within the House of Quality (HOQ) matrices. This study employed systematic procedures that utilized inferential statistics, specifically factor analysis and Spearman correlation, within the context of QFD method. Factor analysis is employed in the process of identifying and selecting the optimal set of unutilized items. The Spearman correlation coefficient was employed to examine and enhance the association between the elements. The findings indicate that there exist significant variables and items that contribute to the enhancement of dry bulk terminal. A study revealed that there exists a moderate and statistically significant correlation between loading time and both labor and machine factors. Additionally, the analysis reveals a substantial correlation between the provision of quality services and the size of the berth. Finally, the analysis reveals a moderate correlation between vehicle control and the operation of lorries. The strategy proposed in this study can be employed by port management to effectively identify solutions in the context of dry bulk terminals.
Sinemada Yavaşlığın Estetiği: Yavaş Sinema Kavramıyla Goodbye, Dragon Inn (2003, Ming-liang) Filmini Düşünmek
Authors: KADIOĞLU Aziz Barkın
Published: December 2023

Modern toplumda yaşamın endüstriyelleşen ve kentlileşen yapısının hızlı akışına karşı önem kazanan “yavaşlık” olgusu, tüketim kültürünün beraberinde getirdiği sorunlara bir tepki niteliği taşımaktadır. “Slow Food”, “Slow City” ve “Slow Media” gibi yavaşlığı bir yaşam biçimi olarak sahiplenen hareketlerle birlikte düşünüldüğünde kavramın kültürel ve toplumsal olarak gelişkin bir ideolojik altyapıya sahip olduğu söylenebilir. 1980’lerin sonundan itibaren Petrini ve Berthelsen’in çalışmalarıyla literatürde daha da görünür hale gelen yavaşlık olgusu özellikle 60’lı yıllar modern sinema anlatılarıyla başlayan ve günümüze uzanan tarihsel bir aralıkta sinematografik tercihler aracılığıyla sinemada da görülmeye başlamıştır. 1980’li yılların sonundan itibaren çeşitli yönetmenler, ana akım sinemaya meydan okuyan yeni bir sinema dilini benimseyerek “yavaş sinema” adı verilen benzerlikler alanı etrafında bir araya gelmeye başlamışlardır. Yavaşlığın seyircinin zaman ile hareketi daha yavaş bir hızda algılamasına olanak tanıyarak, seyircileri düşünmeye ve film evrenine katılmaya davet ettiği ifade edilebilir. Tarr, Akerman, Angelopoulos, Tarkovski ve Bresson gibi yönetmenlerin öncülüğünü yaptığı yavaş sinema, günümüzde Weerasethakul, Zhangke, Hsiao-hsien, Costa, Ming-liang ve Nuri Bilge Ceylan gibi hem ulusal hem de uluslararası kapsamda öne çıkan birçok isimle birlikte tartışılmaktadır. Bu çalışmada yavaş sinemanın öne çıkan isimlerinden biri olan Tsai Ming-liang’ın Goodbye, Dragon Inn (2003) filmi, sinematografik nitelikleri incelenerek yavaş sinema kavramı bağlamında analiz edilmiştir. Sonuç olarak incelenen filmin biçimsel ve anlatısal özelliklerinin yavaş sinema kavramıyla ortaklıklar taşıdığı görülmüş, kapanmakta olan bir sinema salonunu mekân olarak seçmesiyle ise seyir deneyiminde yaşanan değişimlere ilişkin bir söylemde bulunduğu ortaya koyulmuştur.

ASSESSING FISHING ACTIVITY, FISH PRODUCTION AND DEMAND IN ILU ABBA BORA ZONE, SOUTHWEST ETHIOPIA
Authors: Tujuba Ayele  , Melaku Simagegnew , Dobamo Tsegaye
Published: December 2023

The study was aimed to assess fishing activity, fish production and demand outlook in Ilu Abba Bora Zone, Oromia Region, southwest Ethiopia, to generate baseline data that would help in the proper and sustainable utilization of fish resources. Previous reports, field assessment, structured and semi-structured questionnaires and direct observation were employed for data collection. Five districts (Mettu, Yayo, BiloNopa, Bure and Sale Nono) were selected using purposive sampling technique. From each district, fishermen and households along and near riverine water bodies were selected purposively.  The fishing activities of the area are aimed for subsistence by part-time fishermen and for local market during the dry season. The fishing gear commonly used are hooks of different sizes, traps (fish basket) and rarely gillnet. Birbira (Milletia ferruginea) is also used by fishermen in Sale Nono district. Though the severity of the constraints varies from one district to the other, the main fish production constraints in the area are low demand for fish, lack of awareness, lack of facilities, low profit, and long distance to market place. The fish demand and supply in the study area is unbalanced. Fresh whole fish, gutted and dried fish are mostly preferred fish products. Labeobarbus intermedius, Labeobarbus nedgia, Bagrus docmak and Oreochromis niloticus are the species preferred by consumers in the study area. Awareness creation and promotion of local fish farming is important to integrate fish in the community’s diet and to scale up fish demand and supply in the area.
Incidencia de los conflictos sociales en la gobernabilidad y estabilidad social en los ciudadanos de la provincia de Talara, Piura
Authors: Meléndez Biminchumo José Eduardo , Veramendi Vernazza Rossana Teresa
Published: December 2023

Abordar los conflictos sociales resulta importante para comprender la dinámica que existe entre los actores involucrados y poder anticipar escenarios de conflictividad que afecten las estructuras sociales de las comunidades. Los conflictos son inevitables, y representan una oportunidad para crecer como sociedad, no obstante, su gestión es aún un tema que requiere seguir una continua contribución de experiencias dado lo complejo que es tratar con puntos de vista de colectivos. Otro aspecto de relevancia es la estabilidad social, que representa el orden y la pacífica convivencia en una sociedad, los cuales son drásticamente alterados por la presencia de conflictos no gestionados adecuadamente. Por tal motivo el objetivo de esta investigación fue determinar la incidencia de los conflictos sociales en la gobernabilidad y estabilidad social de los ciudadanos de la provincia de Talara en Piura. Estudio realizado el 2023, de tipo básico, de diseño no experimental, transeccional, correlacional-causal y de nivel explicativo. Para esto, se encuestó a 98 ciudadanos elegidos por conveniencia usando tres cuestionarios uno por cada variable, gobernabilidad, estabilidad social y conflicto social debidamente validados por juicio de expertos; para obtener la confiabilidad de los instrumentos se realizó una prueba piloto a 30 ciudadanos de la provincia de Talara, obteniendo valores de alfa de Cronbach de 0.981, 0.984 y 0.943 respectivamente. Por las características de las variables se realizó dos análisis estadísticos, el análisis multivariado de correlación canónica no lineal y la regresión logística ordinal. Dados los resultados, se evidenció que con un ajuste máximo del 54.8% existe incidencia significativa de los conflictos sociales en la gobernabilidad y estabilidad social de los ciudadanos de la provincia de Talara, Piura. Esto indica que existe dependencia de la gobernabilidad y estabilidad social frente a los conflictos sociales.
Mathematical Modeling of Solar Systems
Authors: Kujovic Alma , Mujović Saša
Published: December 2023

The photoelectric effect is the emission of electrons from metals under the action of light.  In 1921, Einstein won the Nobel Prize for explaining the photoelectric effect, which says that light has nature of particulate or light extends in quanta called photons.  More photons eject more electrons, but the energy of the ejected electrons can only increase if the photon's energy rises. The photovoltaic effect and photoelectric effect are not the same concept. These are two directly related terms but the difference is that the photoelectric effect releases electrons from the surface of the material, after exposure to a sufficient amount of energy from sunlight. The photovoltaic effect releases electrons pass between molecules of different material compounds, which causes an increase in voltage between the two electrodes. This discovery is the basis for the development of electricity generation from solar energy. Further development and achievement are given further in the work.

INTEGRAÇÃO DA TEORIA E PRÁTICA NA EDUCAÇÃO CONTEMPORÂNEA: EXPLORANDO AS POTENCIALIDADES DA PRÁXIS PEDAGÓGICA ATRAVÉS DA TEORIA DA ATIVIDADE
Authors: SANTOS DOUGLAS MANOEL ANTONIO DE ABREU PESTANA DOS , Silva Renan Antônio da
Published: December 2023

Este ensaio aborda a relação entre educação e sociedade, destacando a importância da escola como agente de desenvolvimento das funções psíquicas superiores dos estudantes, mediado pela cultura e conhecimentos acumulados ao longo da história. Enfoca-se a necessidade de compreender a escola como um espaço intencional para a formação de indivíduos capazes de agir em prol de uma sociedade mais justa e igualitária, em meio a desigualdades sociais e econômicas que permeiam o mundo preexistente. Contudo, existe uma contradição entre essa concepção de escola como promotora do desenvolvimento integral e a visão que a considera apenas como preparatória para o mercado de trabalho, submetendo-a à lógica de acumulação mercantil. Nesse contexto, este trabalho se propõe a discutir o conhecimento teórico defendido pela teoria da atividade como objeto de aprendizado, sua articulação com a concepção de escola defendida por essa teoria, e como a educação se relaciona com as atuais políticas públicas de educação no cenário nacional.

دور المراة ومكانتها الاجتماعية في الاسلام وفقاً لتعاليم القرآن الكريم والسُّنَّة النبويَّة
Authors: مصطفى محمود ابراهيم
Published: December 2023

دور المرأة في المجتمع الإسلامي لقد جاء الإسلام للناس كافّة، بمختلف منابتهم وأشكالهم وألوانهم صغارا وكبارا، ذكورا وإناثا، فلا فرق بينهم، ولقد أولى الإسلامُ منذ بداية الدعوة المرأة اهتماما خاصا، كما أنه اهتم بحقوق المرأة وكرَّمها، وجعل لها كلمةً مسموعةً في كل وقتٍ وحين، فالمرأةُ كانت قبل الإسلام، تُقتلُ وهي صغيرة؛ لئلّا تجلب لهم العار، هذا زعمُ أهل الجاهلية، لكن جاء الإسلام وأنصفها وأنقذها من مستنقع الجهل ذاك. وقد بين الإسلامُ أن للمرأة دورا هامّا في المجتمع الذي تعيش فيه، فهي مسؤولةٌ مسؤوليةً تشاركيّة مع زوجها في إنشاء جيلٍ مسلمٍ، مؤمن بالله، ذو أخلاقٍ سامية، قدوته رسول الله -صلى الله عليه وسلّم-، فلو أن كلَّ أُسرةٍ عملت بذلك لتغير المجتمع إلى أحسن ما يكون. ومن دور المرأة في المجتمع وهو في العمل أن تختار المجال الذي يُناسب مكانتها والرسالةَ التي تحملها لترتقي بالمجتمع إلى درجةٍ عالية من السمو والأخلاق، وبذلك تكون قد أدت الأمانة الأخلاقية، فتكون مثالًا يُحتذى بهِ للأجيال الصاعدة في مجالات العمل المختلفة كالتعليم والطب والمدرسة.وللمرأة دورٌ في أن تُحافظ على نفسها من أن تكون كما يُروّج أصحاب النفوس المريضة، فهم يُنادون بتحرر المرأة، ولا يريدون من ذلك إلّا حرّية الوصول إلى المرأة، فيجب أن تحذر من هؤلاء الذين يُحرّضون على فساد المجتمع بنشر الشهوات والمنكرات والدعوة إليها. نماذج لدور المرأة في المجتمع الإسلامي سأذكر بعض النماذج للمرأة المسلمة فيما يأتي: دور أم سلمة -رضي الله عنها- في المشورة على رسول الله -صلى الله عليه وسلم- عندما عادوا من صلح الحديبية وكانت نيتهم الحج فعقدوا الصلح، فانتكس الصحابة -رضوان الله عليهم- فما كان من أم سلمة إلا أن تشير على رسول الله بأن يفعل كما لو أنّه عاد من الحج، ففعل ذلك، ففعل الصحابة ذلك وبهِ تغيرت الأجواء وعمت السعادةُ والرضى. دور ذات النطاقين أسماء -رضي الله عنها- عندما كانت تُخاطر بنفسها لتوصل الطعام إلى رسول الله - صلى الله عليه وسلّم- ووالدها أبي بكر، فكانت تسير مسافة بعيدة والأرض شاقة ووعرة والشمس حارقة، فضحت في سبيل الله نُصرةً للدعوة ولنهضةِ المجتمع. دور السيدة خديجة في حمل أعباء الدعوة عن الرسول -صلى الله عليه وسلّم- وكانت من أوائل الذين أسلموا من النساء والرجال، فوقفت مع الرسول-صلى الله عليه وسلم- في الشدة قبل اليسر، فحملت عنه أعباء الدعوةِ ومشاقّها، وجاهدت في سبيل الله بنفسها ومالها -رضوان الله عليها-. مكانة المرأة في الإسلام لقد أولى الإسلام المرأة مكانة عظيمة، وأكرمها بما لم يكرمها به دينٌ آخر، فالنساء في الإسلام شقائق الرجال، فالمسلمة في طفولتها لها حق الرضاع، والرعاية، وإحسان التربية، وما زالت مجتمعات المسلمين، تولي المرأة اهتماما شديدا، وترعاها رعايةً خاصة، امتثالًا لوصايا رسول الله بالنساء وبحفظ المرأة وإكرامها والإحسان اليها.

Authors: Hariharan Sreeram , Marimuthu Uthayakumar , Sundaresan Thirumalaikumaran , Shanmugam Suresh Kumar , Govindhan Radhakrishnan Rajeshkanna , Mierzwinshi Darius , Walter Janusz
Published: December 2023

Wire Electric Discharge Machining (WEDM) has been recognized as one of the optimum methods for machining of harder aluminum-based hybrid metal matrix composites (AHMMC). This method is used to optimize the major control aspects of a machine and they are current, pulse duration, and rate of feed of wire on kerf width (KRW) and Surface roughness (Ra) of hybrid composites made of aluminum Al6351 as the metal matrix (AMMHC). The AMMHC has been created via a stir casting technique by adding SiC and B4C with an Al6351 matrix. Box-Behnken design (BBD) has been used to conduct tests in order to parametrically optimize the WEDM process. The optimization of KRW and Ra is identified using 3-D surface plots, graphs and response table of ANOVA as well as by employing Response Surface Methodology (RSM). Internet of Things (IoT) is implemented to monitor the quality of electrolyte that is used in WEDM. It has been identified that the current has a major contribution in both KRW and Ra factors. A lower current is preferred for a lower KRW whereas higher current improves Ra value.
Understanding the Barriers Limiting SMEsâ€™ Capacity to Participate in Formal Training: A Perspective from an Emerging Market
Authors: Damoah Obi Berko O. , Ashie Augustina Adei , Elias Kekesi Kodjo
Published: December 2023

Whilst SMEs are known to contribute significantly to the socio-economic development of most economies of the world, they are also known to face many challenges which limit their full effectiveness. The present study seeks to explore the factors that limit SMEsâ€™ capacity to participate in formal training programmes from the Ghanaian perspective. The study seeks to identify the extent to which the barriers to training compare and contrast with existing studies, although the extant literature argues that some barriers are more specific to some regions. The study is based on a purposive sample of 85 owner-managed SMEs drawn from the capital of Ghana, Accra. Using the principal component analysis, coupled the mean rankings of the respondentsâ€™ average score as the main analytical tools, the results show that among the eight main barriers that were found, lack of accessibility to training, lack of funds to fund training programme and a negative perception of owner-managers regarding the usefulness of training were the three most important barriers accounting for why SMEs from Ghana find it difficult to participate in formal training and therefore remain inefficient and ineffective compared to their counterpartsâ€™ large firms.Â
Service Quality Variables for Assessing Studentsâ€™ Satisfaction in Higher Learning Institutions: Evidence from Empirical Literature Review
Authors: Uiso Hawa , Magali Joseph
Published: December 2023

The relationship between service quality and studentsâ€™ satisfaction is an important aspect to be observed by Higher learning institutions in order to promote studentsâ€™ enrolment. Service quality influences the studentsâ€™ satisfaction and it is a prerequisite for increased number of graduates and hence educated people in any country. Parasuraman et al. (1988) argued that the assessment of the customersâ€™ overall superiority of service offered is based on service quality. This paper discusses the relationship between service quality and university studentsâ€™ satisfaction from empirical literature review. The objective of this paper was to assess the influence of service quality on studentsâ€™ satisfaction basing on studies conducted in various countries in the world. The findings are, to the authorsâ€™ best knowledge that few studies have been done to assess the influence of service quality on studentsâ€™ satisfaction in Tanzania. The study recommends that there is a need to conduct more studies in higher learning institutions in Tanzania.

Some Studies on Three Dimensional Turbulent Boundary Layer Flows
Authors: Swaminathan R. , Balu R.
Published: December 2023

This paper describes some studies on flow separation and on the extended Cebeci-Smith turbulence and transition models, carried out using a three-dimensional turbulent boundary layer code developed at the Vikram Sarabhai Space Center (VSSC), Thiruvananthapuram, India. This code uses an orthogonal curvilinear surface fitted co-ordinate system. The governing equations are solved, by an implicit space marching numerical method called the Keller Box Scheme with suitable modifications for reverse crossflows. Initial data on two intersecting planes for starting the solution procedure, are obtained by solving the appropriate limiting form of the governing equations. Three transition models available in the Literature are studied. A few sample results are presented and compared with experimental measurements.

Authors: Chakrabartty S. K. , Mathur J. S. , Dhanalakshmi K.
Published: December 2023

Development of Computational Fluid Dynamics (CFD) has now reached a state of maturity, which enables it to simulate the flow past practical aircraft configurations. It can thus play a very useful role in aircraft design and development.

Authors: Patel B.P. , Ganapathi M. , Sambandam C.T. , Giri S.N.
Published: December 2023

In this paper the free vibration behaviours of thick laminated composite non-circular cylindrical shells are investigated using higher-order theory. The formulation accounts for the variation of the in-plane and transverse displacements through the thickness, abrupt discontinuity in slope of the in-plane displacements at the interfaces, and includes in-plane, rotary inertia terms, and also the inertia contributions due to the coupling between the different order displacement terms. The strain-displacement relations are accurately accounted for in the formulation without neglecting/approximating the (I +z/R) terms. The solutions are obtained employing finite element procedure. Detailed study is made to highlight the influences of length and thickness ratios, eccentricity parameter, ply-angles and number of layers on the free vibration characteristics of non-circular shells.

Published: December 2023

Genetic Programming (GP) is used to classify the Acoustic Emission (AE) signal to different source of signals. GP has the ability to discover the relationship among the observed data and express them mathematically. GP based technique has an advantage over conventional statistical technique like maximum likelihood estimate, nearest neighbor classifier and etc, because they are distribution free i.e. no a priori knowledge is required about the distribution of data. The data is obtained through an AE test using pulse, pencil and spark signal source on the surface of solid steel block. The signal parameters are measured using AET 5000 system, A set of expert system like rules is extracted from the GP. These rules are used directly to classify the AE signals. Classification of AE signal using genetic programming is found to be effective.

Computation of Inviscid Flow Past SARAS Aircraft with Sideslip Using A Multi-block Grid
Authors: Dhanalakshmi K. , Chakrabarttv S. K. , Mathur J. S. , Ramesh V.
Published: December 2023

The computation of the flow past an aircraft configuration is a fairly difficult task due to the complexity of the geometry. A powerful multi-block grid generation tool and a robust, well-validated flow solver code are required to compute such a complex flow. A large number of blocks are needed to discretize the flow field and hence considerable time and effort is required to generate a suitable computational grid. If the flow is symmetric, without any sideslip, it is only necessary to solve the flow past half of the aircraft, but for flow with side slip it becomes essential to solve the flow past the complete aircraft, which introduces additional difficulties. This paper describes the computation of inviscid flow past the SARAS aircraft, with sideslip, using a multi-block grid containing sixty-six blocks. An improved blocking strategy is used to keep the number of blocks to a minimum. A detailed analysis of the computed flows, along with a comparison of the aerodynamic coefficients with available experimental results, is presented here. The code has been validated by showing that a symmetric solution is obtained for a symmetric flow condition and the correct anti-symmetry is achieved for flows with opposite sideslip. The computed results show a good agreement with the experimental data.

Published: December 2023

In this paper data partitioning method is applied to concatenated Large amplitude manoeuvres (LAM) of a fighter aircraft to estimate its stabiLity and control derivatives. Stepwise multiple linear regression (SMLR) is utilized to determine the model structure within each partitioned data set. It is shown that the procedure with data generated from a research simulator, yields a useful method for estimating the pitch up tendency exhibited b), the aircraft during certain angle of attack (AOA) range. The SMLR is also applied to estimate non-linear aerodynamic derivatives of the aircraft from LAM data. The method is applied to reaL LAM data of the aircraft and gives reasonably consistent estimates of the aerodynamic derivatives. Results using model error method for the longitudinal derivatives from LAMs are also presented.

Conjugate heat transfer (CHT) analysis has been carried out for laminar flow past flat plate and turbulent flow between parallel plates using a commercial CFD software CFX-TASCFlow. Navier-Stokes equations along with k-e turbulence model in the fluid and conduction equation in the solid have been solved simultaneously to obtain the flow features. The computed temperature distribution of the flow past flat plat matches very welL with analytical and other numerical results. For the turbulent flow between parallel plates, nondimensional temperature distribution and Nusselt number distribution matches very well with the analytical and experimental results for different values of Reynolds number and thickness of the heat transfer plate.
The Cross-coupling Problem of Helicopter Rotors - A Review
Authors: Rosen Aviv
Published: December 2023

Until recently it was beyond the capability of helicopter rotor models to predict correctly the cross-coupling response. During the mid-nineties it became clear that wake distortion effects are the main contributors to the cross-coupling response. Wake distortion effects can be modeled by using detailed free or prescribed wake models. However, these models require large computer resources and long computing times, thus they are not suitable for various applications. In such cases dynamic-inflow models can be corrected to account for the missing effect, by using the wake distortion coefficient or an aerodynamic phase lag. Recently, a new actuator disk model was developed where the wake distortion effect is obtained as an integral part of the derivation. In the paper all the methods of considering the wake distortion effects are reviewed and compared. The results of the various models are also compared to flight test results. Conclusions are drawn and further necessary research is identified.

Advanced Hypersonic Transportation Perspectives
Authors: Gopalaswami R.
Published: December 2023

High-speed transportation design concepts are examined for advanced civil aviation and space transportation applications. The design concept of transatmospheric vehicles, flying directly from earth to orbit, will enable launching and recovery of small telecommunication and remote sensing satellites, harvesting solar energy from space, and space tourism.Commonality of flight regimes in atmospheric flight, the similarity of fuels, propulsion technology, aerodynamic configuration design, and airframe structure materials used in these high-speed flight regimes for air and space transportation are discussed in detail.A single, Integrated Hypersonic Transport Programme, is recommended, based on small size, low risk, and low cost vehicles. A dual fuel, kerosene-hydrogen system meets the needs of such an Integrated Hypersonic Transportation Programme, with kerosene for take-off, powered landing and low speed ascent/descent flight. Hydrogen is used for high-speed cruise flight. India would greatly benefit by an Integrated Hypersonics Transportation Programme, with leading institutions like ISRO, NAL and ADA working together to jointly study, design and build a strong technology base for small, unmanned hypersonic flight demonstrators. This project could then lead on, safely and economically, to hypersonic Executive Jet aircraft, and small fully Reusable Trans-Atmospheric Vehicles for direct ascent of the hypersonic aerospacecraft to earth orbit.

Active Twist Control of Smart Helicopter Rotor - A Survey
Authors: Thakkar Dipali , Ganguli Ranjan
Published: December 2023

Helicopter vibration and blade-vortex interaction (BVI) noise are major problems restricting the wider use of helicopters in civil and military applications. Traditional methods based on vibration isolators and absorbers and passive designs of the rotor blade to reduce BVI noise have reached the point of diminishing returns and are increasingly unable to meet the stringent requirements of next generation helicopters. The advent of smart materials such as piezoceramics, has opened the possibility of actively twisting the rotor blade using control algorithms in a manner such that new higher harmonic forcing is developed which cancels the existing unsteady higher harmonic aerodynamic forces that are the main sources of vibration and noise on the rotor. Since the main rotor of a helicopter is the principal source of vehicle vibration, active twist control offers possibility of a low vibration helicopter. This paper reviews the literature in active twist rotor control using smart materials.

Authors: Ganapathi M. , Prakash T. , Sundararajan N. , Singha Maloy K.
Published: December 2023

The nonlinear formulation developed based on von Karman’s assumptions is employed to study the large free flexural vibration characteristics of functionally graded material (FGM) plates subjected to thermal environment. Temperature distribution is uniform over the plate surface and varied in thickness direction only. Material properties are assumed to be temperature dependent and graded in the thickness direction according to simple power law distribution. The nonlinear governing equations obtained using Lagrange’s equations of motion are solved using finite element procedure coupled with the direct iteration technique. The variation of nonlinear frequency ratio with amplitude is highlighted considering various parameters such as gradient index, temperature, thickness and aspect ratios, skew angle and boundary condition. For the numerical illustrations, silicon nitride/stainless steel is considered as functionally graded material. The results obtained here reveal that the temperature field and gradient index have significant effect on the large amplitude free flexural vibration of the functionally graded plate.
Computational Investigation of Supersonic Jet Screech in Circular Jets Using Higher-order Weno Scheme
Authors: Dharani M. , Chatterjee A.
Published: December 2023

Computational investigation of supersonic jet screech in imperfectly expanded circular jets is conducted using higher order Weighted Essentially Non-Oscillatory (WENO) scheme based solution of the axisymmetric Navier Stokes equations. The jet screech phenomenon is numerically simulated for an over expanded and an under expanded circular supersonic jet. Sound pressure levels, screech amplitude and frequency are calculated from the pressure history in the flow field and compared with values in literature. Shock cell spacings in the high speed jet are also extracted from numerical simulations and compared with that in literature. Important aspects of a screeching jet observed experimentally, like the interaction of instability waves with the shock train and the contribution of downstream propagating hydrodynamic fluctuations to the creation of the upstream moving acoustic wave in the acoustic feedback mechanism, are also captured in the present computations. The latter phenomenon has been observed experimentally but not reported previously in numerical simulations.
Design of Fuzzy Based Attitude Controller for Spin Stabilized Micro-satellite
Authors: Prasanna Kumar R.N. , Lakshmi S. , Shanmugam J.
Published: December 2023

The objective of this paper is to develop an intelligent fuzzy attitude control strategy for detumbling with initial spin-up phase and spin rate control for small, low earth orbit satellite using only magnetometer and torquer. A magnetic moment produced by coils placed on the satellite will produce a resultant torque by interaction with the geomagnetic field, which may be used for attitude control purposes. Nevertheless, this simple, low power consumption approach poses several interesting control difficulties as the geomagnetic field viewed by a satellite, changes along its orbit. Besides this time dependency, this problem’s mathematical description is highly non-linear, and hence a new intuitive control strategy is needed to solve the attitude and control demands of such a satellite. In this work, controllers are designed which, consists of Multi Input Single Output (MISO) fuzzy logic controllers. Also Single Input Single Output controllers are used to control the spin rate. This fuzzy control approach ensures the required performance in the presence of disturbance, uncertainty and various non-linearities and also describes the design of rule based fuzzy logic controller. This structure of the controller takes advantage of classical controllers while maintaining a significant degree of robustness, performance and portability. Furthermore, Simulation studies are illustrated for such control scheme.
