Published: March 2024

Age detection has gotten a lot of attention in recent years because it is being used in more and more sectors. Regulations and norms imposed by the government, security measures, interactions between humans and computers, etc. Facial features and fingerprints are two of the most common human characteristics that may shift or alter throughout time. The nose, on the other hand, maintains a consistent structure that does not alter with the passage of time and possesses the singular capacity to fulfil the prerequisites of biometric attributes. This study gives a comprehensive review of how deep learning algorithms may be used to easily extract aspects of the human nose. In specifically, convolutional neural networks, also known as CNNs, are utilised for the purpose of feature extraction and classification when applied to big datasets that have numerous layers. The proposed methodology collects more private children's datasets, which contributes to a rise in the total number of datasets, which ultimately results in a rise in the 98.83 percent accuracy achieved. The results of this survey may be used to limit the material that is shared on social media by determining the age range of the participants, from under 18 to 18 and older.
OEE-WCRD: Optimizing Energy Efficiency in Wireless Sensor Networks through Cluster Head Selection Using Residual Energy and Distance Metrics
Authors: Lalit Kumar Tyagi  , Kumar Anoop
Published: March 2024

Wireless Sensor Networks (WSNs) play a pivotal role in various applications, including environmental monitoring, industrial automation, and healthcare. However, the limited energy resources of sensor nodes pose a significant challenge to the longevity and performance of WSNs. To address this challenge, this paper presents an Optimized Energy Efficient Protocol in Wireless Sensor Networks through Cluster Head Selection Using Residual Energy and Distance Metrics (OEE-WCRD). This research paper presents a novel approach to cluster head selection in WSNs by harnessing a combination of residual energy and distance metrics. The proposed method aims to significantly enhance the energy efficiency of WSNs by prioritizing nodes with ample residual energy and proximity to their neighbors as cluster heads. Through extensive simulations and evaluations, we demonstrate the effectiveness of this approach in prolonging network lifetime, optimizing data aggregation, and ultimately advancing the energy efficiency of WSNs, making it a valuable contribution to the field of WSNs protocols.
Density of quantized approximations
Authors: Borodin Petr Anatolevich , Shklyaev Konstantin Sergeevich
Published: March 2024

The paper contains a review of known results and proofs of new results on conditions on a set $M$ in a Banach space $X$ that are necessary or sufficient for the additive semigroup $R(M)=\{x_1+…+x_n\colon x_k\in M, n\in {\mathbb N}\}$ to be dense in $X$. We prove, in particular, that if $M$ is a rectifiable curve in a uniformly smooth real space $X$, and $M$ does not lie entirely in any closed half-space, then $R(M)$ is dense in $X$. We present known and new results on the approximation by simple partial fractions (logarithmic derivatives of polynomials) in various spaces of functions of a complex variable. Meanwhile, some well-known theorems, in particular, Korevaar's theorem, are derived from new general results on the density of a semigroup. We also study approximation by sums of shifts of one function, which are a natural generalization of simple partial fractions.

Authors: Alnaser Ala Jamil , Holland James , Sargolzae Arman
Published: March 2024

Testing and verifying the security of connected and autonomous vehicles (CAVs) under cyber-physical attacks is a critical challenge for ensuring their safety and reliability. Proposed in this article is a novel testing framework based on a model of computation that generates scenarios and attacks in a closed-loop manner, while measuring the safety of the unit under testing (UUT), using a verification vector. The framework was applied for testing the performance of two cooperative adaptive cruise control (CACC) controllers under false data injection (FDI) attacks. Serving as the baseline controller is one of a traditional design, while the proposed controller uses a resilient design that combines a model and learning-based algorithm to detect and mitigate FDI attacks in real-time. The simulation results show that the resilient controller outperforms the traditional controller in terms of maintaining a safe distance, staying below the speed limit, and the accuracy of the FDI estimation.
Implementation of Long Assembly Drills for 777X Flap Carriers
Authors: Kuldell Kip , DeVlieg Russell
Published: March 2024

Large diameter, tightly toleranced fastener patterns are commonplace in aerospace structures. Satisfactory generation of these holes is often challenging and can be further complicated by difficult or obstructed access. Bespoke tooling and drill jigs are typically used in conjunction with power feed units leading to a manual, inflexible, and expensive manufacturing process. For 777X flap production, Boeing and Electroimpact collaborated to create a novel, automated solution to generate the fastener holes for the main carrier fitting attachment pattern. Existing robotic automation used for skin to substructure assembly was modified to utilize extended length (up to 635mm), bearing-supported drill bar sub-assemblies. These Long Assembly Drills (LADs) had to be easily attached and detached by one operator, interface with the existing spindle(s), supply cutting lubricant, extract swarf on demand, and include a means for automatically locating datum features. Additional enhancements were implemented to enhance reliability and usability with successful implementation occurring in 2022.

Authors: Koppad Praveennath , Chinnakurli Suryanarayana Ramesh , Reddy Nagaraja , Sethuram D
Published: March 2024

In the aerospace industry, large aircrafts employ composite materials for making complex structures which not only reduces weight and cost but also reduces the number of joints. Irrespective of that joining of structures cannot be avoided and for that mechanical fasteners such as rivets and bolts are employed along with adhesive bonding. Further, in recent years natural fibers have been studied extensively for their numerous advantages and have already been made into several automotive applications. Keeping these current trends in mind an attempt is made to investigate the joining behavior of natural fiber composites experimentally. So in this study, the ultimate failure load, bearing strength and the dominating failure mode of jute-hemp fabric-reinforced polymeric composites joined using single and double-bolted configurations are studied. The polymeric composite laminates were successfully fabricated using resin infusion technique and test specimens were fabricated following ASTM D5961M-10 standard. The ultimate failure load for a double-bolted joint configuration was almost twice that of a single-bolted joint configuration. The failure analysis conducted using a scanning electron microscope revealed net tension as the main failure mode for both cases of bolted joints.
Automated Inspection Utilizing Deep Learning for Polished Skin
Authors: Aoki Naofumi , Ota Takuya , Zaitsu Masayoshi
Published: March 2024

This technical paper reports the development of an automatic defect detector utilizing deep learning for “polished skins”. Materials with a “polished skin” are used in the fabrication of the external plates of commercial airplanes. The polished skin is obtained by polishing the surface of an aluminum clad material, and they are visually inspected, which places a significant burden on inspectors to find minute defects on relatively large pieces of material. Automated inspection of these skins is made more difficult because the material has a mirror finished surface. Defects are broadly classified into three categories: dents, bumps, and discolorations. Therefore, a defect detector must be able to detect these types of defects and measure the defects’ surface profile. This technical paper presents details related to the design and manufacture of an inexpensive automated defect detector that demonstrates a sufficiently high level of performance. The system employs multiple line sensor cameras and image processing including deep learning to find defects. By developing an effective automated inspection method combined with a relatively large apparatus and an appropriate processing algorithm, defect detection performance of the system was found to be equal to or higher than existing visual inspection methods. Furthermore, although the measurement time depends on the size on the piece of material, most inspections take short time to generate a report, which is significantly less than the time needed to conduct a visual inspection. This technology could be used in the automated inspection of large pieces of material with a mirror-surface that are currently inspected visually.

Authors: Chinnakurli Suryanarayana Ramesh , Cheekur Krishnamurthy Srinivasa , H Adarsha , Mukunda Sandeep
Published: March 2024

Additive manufacturing (AM) is currently the most sought-after production process for any complex shaped geometries commonly encountered in Aerospace Industries. Although, several technologies of AM do exits, the most popular one is the Direct Metal Laser Sintering (DMLS) owing to its high versatility in terms of precision of geometries of components and guarantee of highest levels of reduction in production time. Further, metallic component of any complex shape such as Gas Turbine Blades can also be developed by this technique.

In the light of the above, the present work focuses on development of iron silicon carbide (Fe-SiC) complex part for ball screw assembly using DMLS technique. The optimized process parameters, hardness and wear resistance of the developed iron-SiC composite will be reported.

Further, since the material chosen is a metallic composite one, the effect of SiC on the thermal stresses generated during the DMLS processing of Fe-SiC composite will also be discussed. A novel approach to testing of wear resistance of the developed component will also be presented in this paper.

The developed composite component exhibited lesser wear scars even after 1-lakh cycles of operation indicating excellent wear resistance. It is also observed that increased content of SiC in the developed composite results in higher extent of thermal stresses.
Prevention of Operational Errors in Semi-Automatic Riveters by Machine Vision Systems Using Deep Learning

Published: March 2024

This paper reports the development of an operation support system for production equipment using image processing with deep learning. Semi-automatic riveters are used to attach small parts to skin panels, and they involve manual positioning followed by automated drilling and fastening. The operator watches a monitor showing the processing area, and two types of failure may arise because of human error. First, the operator should locate the correct position on the skin panel by looking at markers painted thereon but may mistakenly cause the equipment to drill at an incorrect position. Second, the operator should prevent the equipment from fastening if they see chips around a hole after drilling but may overlook the chips; chips remaining around a drilled hole may cause the fastener to be inserted into the hole and fastened at an angle, which can result in the whole panel having to be scrapped. To prevent these operational errors that increase production costs by requiring repair work, we have developed an operation support system that processes the monitor images so that the operator can distinguish markers before drilling and detect chips before fastening. Initially, we developed rule-based image processing, but it could not achieve sufficient accuracy because of the complexity of defining rules related to images features. Therefore, we turned instead to image processing based on deep learning, and after efforts to achieve the required accuracy and processing speed, the developed system now outperforms the rule-based system and we have improved the production efficiency of this riveter. Deep learning technology can be used to improve the productivity of a wide range of production equipment, both existing and new.

Ölüm ve Yas Ritüelleri: Din, Modernizm ve Batı Medeniyetleri Ekseninde Bir Değerlendirme
Authors: YELBOĞA Nurullah
Published: March 2024

Geçmişte hayatın bir parçası olarak kabul edilen ölüm; modern hayatın baskın hale gelmesiyle görmezden gelinmiş, “yokmuş gibi” davranılmış ve hayatın içinden koparılıp atılmaya çalışılmıştır. Modern dönemde sergilenen bu tutumlar ise yasın gizli yaşanmasına, cenaze törenlerinin önemini yitirmesine ve mezarlıkların yerleşim alanlarının dışına (yeterince uzak) kurulmasına sebep olmuştur. Dolayısıyla başlangıçta topluma ait olan ölüm fenomeni ve yas ritüelleri, zamanla aile ve yakın çevreye ait ve küçük bir grup tarafından üstlenilen bir olguya dönüşmüştür. Yas tutma biçimleri üzerinde etkili olan inanç sistemleri boyutuyla bakıldığında Hristiyan geleneğinde yas ve matemin uygun görülmediği ve dolayısıyla aşırılığa giden yas eylemlerinin yasaklandığı görülmektedir. Yahudi geleneğinde ise yas ve matem, ölüm olayının önemli bir boyutunu temsil etmekte ve yas adetlerine bağlılık gösterilmektedir. Ancak günümüzde hem Batı Hristiyan hem de Yahudi toplumlarında düzenlenen törenler, merasimler ve yas adetleri eski görkemini ve önemini kaybetmiştir. İslam anlayışı perspektifiyle duruma bakıldığında ise yas adetlerinin, İslamiyet öncesinde kutsal görev olarak kabul edildiği ancak uzun süreli ve taşkınlık derecesinde tutulan yas adetlerinin İslamiyet ile birlikte yasaklandığı görülmektedir. Sonuç olarak, ritüel ve yas tutmada aşırılık uygun görülmemiş, inançsal ve kültürel ögelerin biçtiği sınırlar ölçüsünde ölüm ve yas ritüelleri varlığını sürdürmüştür. Ölüm etrafında şekillenen törenlere ve yas adetlerine ise asıl darbeyi modernizm vurmuştur.

Analyzing the Failure of a Truck's Rear Axle Shaft Requires a Thorough Investigation to Pinpoint the Root Cause of the Issue
Authors: Ashish Kumar , Pandey Sumit Kumar , Diwakar Daya Shankar
Published: March 2024

The analysis of a failed rear axle shaft from a dumper truck involved a comprehensive investigation to ascertain the underlying cause of the failure. Visual inspection, material analysis, mechanical testing, and fracture analysis were conducted to assess the condition of the axle shaft. The axle shaft exhibited signs of fatigue failure, with the fracture surface showing fatigue striations. Microstructural analysis revealed a coarse grain structure with inclusions, indicating potential material defects. Tensile testing showed that the axle shaft had lower-than-expected mechanical properties, suggesting a possible issue with material quality or heat treatment. Based on the analysis, the root cause of the failure was determined to be a combination of material defects and fatigue loading. Types of investigation like as visual examination, chemical analysis, hardness test, tensile test, fractography and ultrasonic test, and microstructure examination. Microstructure observation of the sample indicates a normal ferrite–pearlite (lower critical point) sorbite-type structure with some spheronization seen on some portions Results indicate that the failure occurred due to a sudden load on the axle shaft, specifically at its weakest point. The shear stresses on the axle shaft were insufficient to withstand the stresses caused by the sudden loading. Based on the analysis, make recommendations for corrective actions to prevent similar failures in the future. This may include design improvements, material changes, maintenance procedures, or operational changes. This may include design improvement, material changes, maintenance procedures, and operational changes. Implement the recommended corrective actions to prevent similar failures in other axle shafts or similar components.
Optimizing and Redesigning the Vertical Milling Fixture for Friction Stir Welding of Aluminium Alloy (Al 6061)
Authors: Diwakar Daya Shankar , Pandey Sumit Kumar , Ashish Kumar
Published: March 2024

Friction stir welding is a kind of solid-state fusion process for welding like or unlike metals. Established and patented by “The Institute of Welding” in the UK in December 1991, it involves using a compressive force applied by a conventional milling machine to make contact with work-pieces. The work-pieces are one or the other revolving or moving proportional to a pin tool, generating the heat necessary for atomic diffusion and thereby uniting the material at the edges. FSW can be functional in a variety of materials, together with stainless steel, aluminium, and various alloys. The process typically takes place on vertical milling machines, requiring a vertical milling fixture to firmly hold the plates being welded. In this paper, vertical milling holding setup and fixture for FSW procedures on vertical milling machines are established. Materials such as aluminium and aluminium alloy (Al 6061) are analyzed for their suitability in FSW operations, to identify the best material for the process. Additionally, there is potential for extending the FSW process to plastics and similar materials. Friction stir welding offers significant advantages in terms of weld quality, strength, and versatility across a range of industries, making it a versatile option for solid-state joining processes.

The main cluster that provides shared value for PT Paragon Technology and Innovation consumers is cluster 2 or beauty enthusiast customers. The main category for shared value is the make up category, referring to the result, we recommend PT Paragon to mainly developa product following that category.
Client and Therapists’ Subjective Understanding of an Ideal Therapy Room: A Divergent Reflection of Experience
Authors: Taiwo Abigail , Chinyio Ezekiel , Hewson Helen , Agberotimi Samson
Published: March 2024

An abundance of studies showed that the room/space where therapy takes place could significantly impact the engagement, process, and how people experience therapy. The need to balance the comfort of the room with its fundamental functionality to clients is essential. Nevertheless, studies that report on the perception of therapists and clients about an ideal therapy room are scarce. This study, therefore, aimed to explore the subjective understanding of what makes an ideal therapy room from the perspective of clients and therapists.

The study utilised a qualitative descriptive research design and adopted a grounded theory method. Eight participants (three therapists and five clients) volunteered to participate in the study. The participants were purposively recruited for the study and participated in individual semi-structured interviews. Data obtained were transcribed verbatim and subjected to thematic analysis.

Results showed divergent views among the participants about what constitutes an ideal therapy room. Confidentiality, spatial environment, contextual awareness, and privacy were the key emergent themes. Several subthemes pointed to comfortability, brightness, colour, nice viewing, and focus points as recurrent issues determining how ideal the participants perceive a therapy room.

Conclusion

The results align with Rapoport’s (1992) meaning of the built environment, which emphasises the variability of peoples’ reactions to the environment in terms of its meanings.

Implication

The study implicates the need for therapists working with clients in therapy rooms to consider what the room means to their clients and tailor the environment to suit their clients’ preferences as much as possible or make this an object of exploration at the start of the session. The built environment designers will also benefit from considering these points perceived as significant.

Participants were 49 students of Color (81.6% female), identifying as Black (34.7%), Asian (30.6%), Latinx (22.4%), Arab or Middle Eastern (6.1%), and Multiracial (6.1%). Students’ open-ended descriptions of their experiences were analyzed using Consensual Qualitative Research – Modified. Six categories emerged from responses: support, racial discrimination, marginalization, lack of representation, hypocrisy, and positive changes/attempts. The results demonstrate that these students’ experiences range from feeling supported and seeing positive changes made in their program, to feeling isolated and discriminated against within them. Considerations for ongoing support of doctoral students of Color in counseling psychology programs are discussed, and approaches to developing anti-racist program culture are presented.

This case report presents a conservative management approach to a potentially hazardous complication, iatrogenic coronary artery dissection (ICAD), occurring during percutaneous coronary intervention (PCI). The patient, a 60-year-old woman with a history of chronic hypertension and type II diabetes mellitus, presented with non-ST-segment elevation myocardial infarction. During the PCI, an antegrade coronary dissection was observed, leading to the termination of the procedure. Post-procedure, the patient was managed conservatively with standard coronary artery disease treatment. Follow-up angiography showed complete healing of the dissection area, and no adverse cardiovascular events occurred during a 3-month follow-up period. This report highlights the importance of early diagnosis and careful management of ICAD. It stresses the need for further research into long-term outcomes and effectiveness of different treatment approaches for patients with ICAD.

The development of information and communication technology in modernization has revolutionized learning and access to information. This study aims to describe the socio-cultural changes in educational institutions and how to implement the learning process in digital literacy. This study uses a qualitative approach using literature reviews such as academic articles, research papers, and books that explore the relationship between modernization, technology, and socio-cultural change, emphasizing the role of the learning process. The results show that there are socio-cultural changes in the scope of educational institutions amid technological modernization. Technological developments affect learning methods in an educational institution. Technology is also changing how teachers and students seek learning resources. Technology also creates how distance learning can be done using video conferencing platforms. The impact of technology and modernization has changed the way students interact and communicate in the school environment. Educational institutions also try to adapt the curriculum to the needs of modern society. The digital literacy-based learning process also has an impact when the vast internet technology and information technology global knowledge have become more accessible through local or national and international dimensions.

The false clownfish (Amphiprion ocellaris) is a prominent species in the marine ornamental trade, valued for its vibrant orange-red coloration. However, aquaculture-bred individuals often exhibit less intense coloration than their wild counterparts, presenting a challenge for both breeders and aquarists. This study evaluates the effects of carotenoid-enriched diets, sourced from natural ingredients such as pumpkin, bell pepper, carrot, and gac, as well as a synthetic source like astaxanthin, on the coloration and growth of false clownfish. In a controlled experiment, juvenile fish with an initial average length of 3.21 ± 0.03 cm and weight of 0.61 ± 0.02 g were allocated to 60-liter tanks and fed the experimental diets over a 75-day trial period. Carotenoid supplementation was standardized at 250 mg/kg across diets, with a control group receiving no added carotenoids. The experimental design was completely randomized, involving three replicates per dietary treatment. The results indicated that diets supplemented with gac and bell pepper significantly enhanced growth and feed efficiency (p < 0.05). Notably, the skin redness intensity (a* value) was increased by 75.73% in the gac-supplemented group, 89.20% in the bell pepper group, and 91.99% in the astaxanthin group, relative to the control (p < 0.05). Additionally, carotenoid deposition in the integument was significantly higher in all supplemented groups, with an increase of 83.74% in the astaxanthin group, 89.59% in the gac group, and 98.43% in the bell pepper group, compared to the control (p < 0.05). These findings suggest that natural carotenoids, particularly from gac and bell pepper, can be effective alternatives to synthetic astaxanthin, potentially improving the attractiveness and commercial value of captive-bred false clownfish and alleviating the exploitation of wild populations.

Tutoring provides a process of learning assistance to children to overcome learning difficulties. Currently, there are many tutoring or tutoring institutions that have special programs for preparation for entering state universities. Along with the emergence of Bimbel, it makes parents or students experience difficulties in making choices. To choose the right Bimbel institution, you need to know one by one the profile and services provided by that institution. This will take a long time to make a choice. This study aims to build a Decision Support System (SPK) using the Weighted Product (WP) method to determine tutoring institutions so that parents or prospective students can make the right choices and according to their needs. The WP method can obtain the best alternative based on multiplication between attributes and each attribute is first raised to the power of its weight. Based on the case studies conducted, the highest preference score was obtained for Ganesha Operation (A2) with a value of 0.259, followed by Latis Supercamp (A4) with a value of 0.251, Nurul Fikri (A3) with a value of 0.247 and Brain Academy with a value of 0.244. The results of the DSS which are built with the results of manual calculations get the same value. Besides that, in testing using Black-Box Testing, all functionality can run as it should.

Garbage is an item that no longer has any benefits for its users, which is the residue from the results of daily human activities or is the result of natural processes that have a solid form. The existing waste processing is only limited to conventional waste processing, which is only transported from the waste-producing place to the Temporary Disposal Site (TPS) and then just dumped into the TPS without processing it first, even though the rules for waste management procedures that must be carried out are: waste collection is then recycled and disposed of to the TPS, then the waste is transported to be disposed of at the Final Disposal Site. Therefore, in the process of waste management, it is necessary to separate waste into organic and non-organic waste. However, most people still have difficulty in sorting organic and non-organic waste, so an application is needed to help socialize waste sorting to the community. In this study, the Least Square Support Vector Machine (LS-SVM) method will be used to classify the types of waste. Meanwhile, to perform the texture extraction process from the included garbage image, the Gray Level Co-occurrence Matrix (GLCM) method will be used. The result of this research is a waste classification application that can provide knowledge and add insight for users, especially in distinguishing the types of organic waste and inorganic waste. The application of the GLCM and LS-SVM methods in the built application can detect types of organic and inorganic waste with a success rate of 97%.

Data clustering provides an overview of the grouping of data through classification so that the groups have levels that have the same category. Cluster classification is carried out on agricultural data in Jambi Province with agricultural production groups including rice, rubber, palm oil, and coffee in the period 2021 for 11 (eleven) cities/districts including Jambi City, East Tanjung Jabung Regency, Sungai Full City, Kerinci Regency, Muaro Jambi Regency, West Tanjung Jabung Regency, Merangin Regency, Sarolangun Regency, Batanghari Regency, Tebo Regency, and Bungo Regency. The purpose of the cluster is used for allocations related to the budget, land, and support that can be used both to increase the amount of production and evaluation related to agriculture, especially at the Jambi Province level. So that the clustering carried out using the Weka application is 4 clusters, the result is that the cluster process stops at the 2nd iteration, the output information that occupies cluster 0 is 3 cities/districts, cluster 1 has 1 city/regency, cluster 2 has 2 cities/districts, and cluster 3 there are 5 cities/districts, with a total attribute of 11 (eleven) city/district data. Based on experiments on manual clustering, it can be concluded that the equations that can be seen from the output results using Weka and manual calculations are the same as doing two data iterations and with the same data group results.

Cardiovascular diseases (CVDs) are the number 1 cause of death globally, taking an estimated 17.9 million lives each year, which accounts for 31% of all deaths worldwide. Four out of 5CVD deaths are due to heart attacks and strokes, and one-third of these deaths occur prematurely in people under 70 years of age. Heart failure is a common event caused by CVDs and this dataset contains 11 features that can be used to predict a possible heart disease. People with cardiovascular disease or who are at high cardiovascular risk (due to the presence of one or more risk factors such as hypertension, diabetes, hyperlipidaemia or already established disease) need early detection and management wherein a machine learning model can be of great help.
