THERMAL AND STRUCTURAL ANALYSIS OF A COOLED TURBINE BLADE USING ANSYS
type: item
description: Gas turbine blades operate under extremely high temperatures that exceed allowable metal limits. Effective internal cooling is therefore essential to maintain structural integrity and prolong service life. This study presents a coupled steady-state thermal and static structural analysis of a turbine blade incorporating ten internal cooling passages. A reduced-order modeling approach is implemented in ANSYS Workbench, where three-dimensional solid elements represent the blade and one-dimensional fluid elements simulate coolant flow. The thermal analysis evaluates temperature distribution in both solid and coolant domains, while the structural analysis determines thermally induced stresses resulting from constrained expansion. Results show significant temperature gradients between the hot external surface (568 K) and cooled internal regions (minimum 338 K). The maximum von Mises stress reaches 2.79 × 10⁹ Pa near critical cooling passages. The study demonstrates that reduced-order thermal-fluid modeling provides computational efficiency while maintaining physical accuracy for preliminary design evaluation.

THERMAL AND FLOW ANALYSIS OF A PARABOLIC TROUGH COLLECTOR USING CFD WITH NANOFLUIDS
type: item
description: Parabolic Trough Collectors (PTCs) represent one of the most mature and commercially deployed technologies in Concentrated Solar Power (CSP) systems. The thermal performance of PTC systems strongly depends on the thermophysical properties of the working fluid circulating inside the absorber tube. Conventional heat transfer fluids such as water exhibit limited thermal conductivity, which restricts system efficiency. To overcome this limitation, nanofluids have emerged as promising advanced heat transfer media. This study presents a comprehensive Computational Fluid Dynamics (CFD) analysis of a parabolic trough collector using ANSYS Fluent. Water-based nanofluids containing CuO, Al₂O₃, TiO₂, and SiO₂ nanoparticles at 0.2 volumetric concentration were investigated. The finite volume method was used to solve the governing continuity, momentum, and energy equations under steady-state conditions. Solar radiation effects were modeled using the Solar Load Model combined with the Surface-to-Surface (S2S) radiation model.

STRUCTURAL INTEGRITY ASSESSMENT OF A TWO-STAGE DISK WITH PINHOLES UNDER STATIC CONDITIONS
type: item
description: Multistage cyclic symmetry analysis enables efficient simulation of complex rotating structures composed of multiple cyclically symmetric subsystems with differing sector counts. This study presents a static structural assessment of a two-stage rotating disk with stress-relief pinholes using multiharmonic cyclic symmetry analysis in ANSYS Mechanical (Release 2025 R2). The inner stage consists of 11 sectors, while the outer stage contains 16 sectors. Although subjected to axisymmetric centrifugal loading at 100 rad/s, interstage coupling generates non-axisymmetric internal force distributions, requiring inclusion of multiple harmonic indices to ensure displacement continuity and accurate stress prediction. The results demonstrate that single-harmonic (HI = 0) analysis leads to interface discontinuities, while multiharmonic enrichment restores compatibility and produces physically consistent deformation patterns.

STRUCTURAL INTEGRITY ASSESSMENT OF A NUCLEAR PIPING SYSTEM UNDER SEISMIC CONDITIONS
type: item
description: Accurate modeling of pipe elbows is critical in seismic assessment of nuclear piping systems, as curved sections exhibit amplified flexibility, ovalization, and nonlinear stress behavior compared to straight pipes. This study evaluates the performance of ELBOW290 elements in ANSYS Mechanical against detailed SHELL281 shell models for nonlinear seismic analysis. A two-stage global–local methodology is adopted. The global piping system is analyzed using line elements to extract seismic displacement histories, while a critical elbow is studied using both ELBOW290 and SHELL281 elements. Material nonlinearities are modeled using Multilinear Kinematic Hardening (global) and Chaboche Nonlinear Kinematic Hardening (local). Results demonstrate that ELBOW290 accurately captures stress concentration, ratcheting, and ovalization effects with less than 5% deviation from shell models while reducing computational cost by approximately 86%. The study validates elbow element technology as a reliable and efficient solution for seismic qualification of nuclear piping systems.

STRUCTURAL ANALYSIS OF BONDED AND HYBRID JOINTS IN AIRCRAFT FUSELAGE CONNECTIONS
type: item
description: Composite materials are increasingly used in modern aircraft structures due to their high strength- to-weight ratio, corrosion resistance, and design flexibility. Aircraft fuselage structures rely heavily on efficient joining methods for stringer-skin connections and splice joints. Traditional riveted joints, bonded joints, and hybrid joints (bonded + riveted) are commonly used in aerospace applications. This study presents a comparative structural analysis of bonded, riveted, and hybrid joints used in aircraft fuselage splice connections. A Z-stringer model was developed using ANSYS SpaceClaim and analyzed using ANSYS Workbench. Static structural simulations were performed to evaluate total deformation and equivalent (von Mises) stress distribution.

STATIC STRUCTURAL AND MODAL ANALYSIS OF A MULTISTAGE AXIAL COMPRESSOR USING MULTISTAGE CYCLIC SYMMETRY
type: item
description: Multistage cyclic symmetry analysis provides an efficient framework for evaluating complex turbomachinery assemblies composed of multiple cyclically symmetric subsystems with different sector counts. This study presents the static structural, modal, and prestressed modal analysis of a four-stage axial compressor model consisting of three blade rows and a supporting rim. Each stage is modeled as an independent cyclic subsystem and connected using multistage interstage coupling. The structure is subjected to rotational speed, stage-wise pressure loading, and thermal gradients to simulate realistic operating conditions. Static results show stress concentration at blade roots and interstage interfaces, while modal analysis reveals harmonic-index-dependent vibration behavior. Prestressed modal analysis demonstrates centrifugal stiffening effects and frequency shifts under operational loads.

Exploring the Mechanical Properties of mild steel by depositing metal oxide nano particles during Arc Welding process
type: item
description: Conventional welding techniques are used to join the conductor metals like copper is a very tedious and costly task as it tends to form oxides during welding which gives a poor weld strength which is not feasible. Alternative means of welding like Arc welding has established itself across a wide range of industries as a cost- effective method for welding these kinds of metals. Welding is commonly used in both automotive and aerospace industries. The objective of this work is to study the strength of the metal before welding and after welding by using different electrodes and depositing metal oxide nano particles during arc welding process. The material chosen for this process is copper of 1.5 mm thickness, mild steel of 4 mm and 5 mm thickness for welding purpose. Hardness of the welded area will be calculated by using Rockwell Hardness Test. Microstructures of the welded area were done by using optical microscope.

type: item
description: This study presents a bio-inspired UAV that combines the exceptional flying skills of albatrosses and falcons, providing a versatile option for high-tech data collecting and monitoring of the environment. Falcons are perfect for traversing complex and dynamic situations, like as thick woodlands or urban areas, because to their fast dives, agility, and nimble movements. Albatrosses, on the other hand, are great at traversing huge areas like deserts and seas because they glide smoothly over great distances with little exertion. By fusing these two distinct flying traits, the Falcon-Albatross Hybrid UAV is able to glide for extended periods of time and move quickly and precisely, making it suitable for a variety of habitats. The UAV can gather high-quality environmental data across vast regions for long periods of time and perform thorough ecological monitoring thanks to its sophisticated sensors and hybrid propulsion system. Not only does the bio-inspired design help with conservation and sustainable management of the environment, but it also opens up new avenues for monitoring ecosystems and detecting environmental changes in a variety of settings. Using simulations in Autodesk CFD and Autodesk Fusion 360, this research compares the UAV's flying efficiency, stability, and data gathering capabilities in detail. It shows that there are considerable improvements in energy efficiency and adaptability compared to traditional UAV designs.

Using diesel and blends of turmeric leaf oil to reduce emissions and improve the efficiency of variable compression ratio engines
type: item
description: A growing need for renewable energy sources has resulted from research into possible replacement fuels for internal combustion engines. This research examines the effects of using turmeric leaf oil (TLO) as a biofuel in a variable compression ratio (VCR) engine with the goal of increasing efficiency and decreasing exhaust emissions. The experiments used a single-cylinder, four-stroke diesel engine that operated on different compression ratios, from 19.5:1 to 18.5:1, and under different loading situations, from 5 to 9 kg. We measured the brake thermal efficiency, volumetric efficiency, and specific fuel consumption (SFC) of diesel blends with varying amounts of TLO (B50, B60, and B70) to see how well they performed. When the engine load increases, the results show that TLO integration somewhat reduces volumetric efficiency but significantly increases brake thermal efficiency.

MECHANICAL PROPERTIES & APPLICATIONS OF NATURAL FIBRE-BASED COMPOSITE MATERIALS
type: item
description: The majority of the research focuses on characterizing natural fibers and comparing their mechanical behavior and application performance to that of traditional composites. A wide variety of natural fibres exist, each with its own set of characteristics that determine which commercial uses for each are most appropriate. Because these materials are naturally occurring, their characteristics may vary greatly depending on the harvesting site and other factors; this makes it challenging to choose the best fiber for a given task. This study presents a thorough evaluation of the characteristics of natural fibers used to reinforcing composite materials in an effort to chart the relative positions of the various fiber types with respect to a number of attributes. Also included is the most recent research on emerging fiber kinds. Here we provide the results of a bibliometric analysis of papers on the use of composites made of natural fibers. There is also a discussion and presentation of a prospective analysis of the tendencies in the future of natural fiber applications and the necessary advances to expand their uses. Green composites made of natural fibers have many potential uses in the automotive and industrial sectors.

MAGNUM MARANGONI FLUID FLOW ACROSS A CIRCULAR SURFACE: THE ROLE OF THERMAL RADIATION AND PRESSURE
type: item
description: Taking into account the pressure work and surface tension, computational work has been carried out on a magneto Marangoni boundary layer that is thermally radiative on a heated circular surface. A system of ordinary differential equations describing various physical characteristics constitutes the numerical model of the present investigation, which was evolved from the governing partial differential equations with appropriate boundary conditions. Increasing the buoyancy parameter raises the magnitudes of the velocities, according to the numerical study of the effective variables, but the magnetic parameter and the ratio of the surface tension had the reverse impact. As the magnetic effect was amplified, the temperature magnitudes rose. The results showed that the Nusselt number is improved by the Marangoni ratio number, the Prandtl number, and the buoyancy parameter.

PRIME HYDRODYNAMIC PERFORMANCE AND ACOUSTIC PROFILE IN UNDERWATER VEHICLES: OPTIMIZING PROPELLER GUARDS PARAMETERS
type: item
description: The development of propulsion systems for underwater vehicles, including AUVs and ROVs, that optimize thrust while minimizing noise pollution caused by humans is becoming more important because to the wide range of uses for these vehicles. Little is known about how to optimize the propeller guards of underwater vehicles, despite the fact that these components change hydrodynamics and affect thrust and noise. There is a lack of research on the effects of guarded propellers on the propulsion efficiency of underwater vehicles and a missed chance to improve environmental outcomes since much of the existing literature focuses on surface vehicles and open propeller designs. In order to find the best design, this study used parametric computational fluid dynamics (CFD) to examine 75 different propeller guard designs. A custom-built equipment was used to measure thrust generated and noise created in order to confirm these findings. Six guard configurations were chosen at random from the parametric research spanning three guard lengths. When it came to measuring thrust, the experimental findings were in agreement with the model-based expectations. Assuming the thrust findings are correct, any parametric study configuration that produces more thrust than the open propeller would be even better. Out of the six experimental guards, four showed noise reductions below the open propeller of 0.01 dB to 10.29 dB. A 5.86% increase in thrust and a 1.08 dB reduction in noise were achieved by the experimental propeller guard design with the highest efficiency. Optimizing propeller guards may improve underwater vehicle performance and reduce noise pollution, according to this research. Research into other testable criteria, improvements to the testing equipment, and assessment of guarded propellers for use in actual underwater vehicles are all potential next steps.

MACHINE LEARNING BASED IRIS RECOGNITION MODERN VOTING SYSTEM
type: item
description: Based on the iris recognition system and related technologies, one of the primary outcomes of the validation system is the fingerprint-based system. The whole biometric procedure is much more genuine and distinct than the other kinds of validation procedures and recognition systems. This has given people creative ideas for their everyday lives. In general, the multimodal biometric process has used a variety of applications to appropriately address the most important and relevant shortcomings of the "unimodal biometric system." In general, the complete process has been incorporated, taking into account the appropriate noise sensitivity, population coverage regions, situations of variability involving both intra- and inter-class concerns, vulnerability involving potential hacking, and non-universality criteria. The machine learning system with a deep learning orientation has been the primary topic of the whole research article. Convolutional neural network (CNN) technology has been primarily used in the fingerprint-based iris recognition system to provide accurate human validation. The iris recognition system has mostly been used in relation to the "high security protection system with actual fingerprints" in the current data validation procedure. The optimal uniqueness, reliability procedure, and appropriate "validity of the iris biometric validation system" for the real goal of person identification have been briefly discussed throughout the whole text.

PREDICTING BEHAVIOR CHANGE IN STUDENTS WITH SPECIAL EDUCATION NEEDS USING MULTIMODAL LEARNING ANALYTICS
type: item
description: Students with special education needs (SEN), whose behavior and learning are particularly sensitive to their bodily conditions and surrounding surroundings, have new options due to the availability of educational data in innovative methods and forms. In order to elucidate the underlying educational insights, multimodal learning analytics (MMLA) collects student and learning environment data in a variety of modalities and analyzes it. In this study, we used MMLA to predict how SEN kids would behave after they get applied behavior analysis (ABA) treatment. ABA therapy is a kind of special education intervention that tries to cure behavioral issues and promote positive behavior changes. Here, we demonstrate how our deep neural network and machine learning models can optimally predict the behavior change of SEN kids with 98% accuracy and 97% precision by importing multimodal educational data. We also show how predictive models with merely standard educational data may perform statistically much better when combined with environmental, psychological, and motion sensor data. Since 2020, the Integrated Intelligent Intervention Learning (3I Learning) System in Singapore and Hong Kong has improved intense ABA therapy for more than 500 SEN kids thanks to our efforts.

HYBRID FEATURE BASED PREDICTION OF SUICIDE RELATED ACTIVITY ON TWITTER
type: item
description: Globally, the number of suicide deaths rises year, which is a troubling public medical concern. Through this experiment, casual, inactive individuals were organically disengaged from online life on Twitter and from sharing self-destructive ideas. Initial emotional evaluation of the idle locations was followed by a thorough comparison with random factors suggested by space experts. With the increasing normalcy of long-distance interpersonal communication platforms, clients have come to rely on these spaces for very sensitive conversations, including thoughts of suicide. The tweets are important for research because of the high frequency of information appearing in them and the considerable capacity and time constraints that computations using them must meet. Emoticons and synonyms features can now be distinguished, and the ngram model—a combination of Unigram, Bigram, and Trigram with half breed word reference—is used to calculate scores. Using machine learning methods, this model uses the informal points to predict how sincere the postings will be. In this study, we also contrast several methodologies such as SVM, NB, and RF.

EPILOTS: A SYSTEM TO PREDICT HARD LANDING DURING THE APPROACH PHASE OF COMMERCIAL FLIGHTS
type: item
description: A go-around might have saved more than half of all commercial aircraft operating accidents. The total accident rate in the aviation business may be lowered by making the choice to do a go-around maneuver in a timely manner. In this study, we report on the development of a deployable machine learning system for the cockpit that facilitates go-around decision-making by the flight crew in the case of a hard landing. This paper provides a hybrid technique for hard landing prediction that feeds a neural network with features modeling the temporal interdependence of aircraft characteristics. The findings demonstrate that our technique has an average sensitivity of 85% and an average specificity of 74% at the go around point, based on a large dataset of 58177 commercial flights. Thus, our method—a cockpit-deployable recommendation system—performs better than previous methods.

LIVER DISEASE PREDICTION USING SVM AND NAÏVE BAYES ALGORITHMS
type: item
description: When it comes to automated illness detection and prediction, data mining is a crucial component. The process uses data mining algorithms and methods to examine health records. One of the leading causes of death in a number of nations is liver disease, which has been on the rise in recent years. Predicting liver disease using classification models built from datasets of liver patients is the goal of this thesis. This thesis improved the prediction accuracy of Indian liver patients in three stages by constructing feature models and comparing them. The first step is applying the min max normalization technique to the original datasets of liver patients obtained from the UCI repository. During the second step of liver dataset prediction, a subset of the normalized liver patient dataset is produced using PSO feature selection. This subset contains just the most important features. In the third step, the data set is subjected to categorization methods. In the last stage, we'll figure out how accurate it is by calculating the root mean square and root mean error values. After using PSO feature selection, the J48 method is thought to be the superior algorithm in terms of performance. The assessment is concluded by looking at the accuracy values.

UNSUPERVISED MACHINE LEARNING FOR MANAGING SAFETY ACCIDENTS IN RAILWAY STATIONS
type: item
description: Railroad operations must be reliable, easily accessible, well-maintained, and safe (RAMS) in order to move both passengers and freight. An important everyday safety issue in many metropolitan areas is the danger of accidents at train stations. In addition to casualties, public worry, and financial losses, accidents wreak havoc on market reputation. Stations like this are feeling the heat from increased demand, which is putting a strain on infrastructure and making safety a top administrative priority. The use of unsupervised topic modeling to better understand the contributors to these severe incidents is advised for the purpose of analyzing them and using technology, such as AI approaches, to increase safety. This study aims to optimize Latent Dirichlet Allocation (LDA) using textual data collected from RSSB, which includes 1000 accidents that occurred at UK railway stations, with the purpose of reducing mortality accidents at these locations. To improve station safety and risk management, this study details the use of a machine learning topic approach to systematic detect accident characteristics, and it offers advanced analysis. The research assesses the effectiveness of text mining from accident records in obtaining information, lessons learned, and a comprehensive understanding of the risks associated with evaluating accidents that result in deaths on a large and long-term scale. Predictive accuracy for important accident data, including hotspots at railway stations and underlying causes, is shown by this Intelligent Text Analysis. In addition, the advancement of big data analytics allows for a better understanding of the nature of accidents compared to restricted domain analysis of accident reports, which was previously impossible without a large quantity of safety history. A new age of useful and widespread artificial intelligence applications in railway sector safety and other domains for safety applications has dawned, made possible by this technology's hig…

HAND GESTURE USING CONVOLUTIONAL NEURAL NETWORKS
type: item
description: The goal of Sign Language Recognition (SLR) is to enable deaf-mute individuals to communicate with the general public by translating sign language into text or voice. Despite the wide-ranging societal effects, the intricacy and wide-ranging hand motions make this work very difficult. Current state-of-the-art SLR approaches construct classification models using manually-crafted characteristics that characterize motion in sign language. Nevertheless, trustworthy features that can adjust to the wide variety of hand movements are challenging to build. In order to tackle this issue, we present a new convolutional neural network (CNN) that can automatically, and without human intervention, extract discriminative spatial-temporal characteristics from unprocessed video streams. Convolutional neural networks (CNNs) are trained to improve performance by feeding them multi-channel video feeds that include color information, depth clues, and the locations of the body's joints. By comparing it to more conventional methods that rely on manually created features, we show that the suggested model outperforms the former on a real-world dataset acquired using Microsoft Kinect.
