Published: August 2023

Developing and designing engineering materials with desirable properties, such as high strength to weight ratio, formability, corrosion resistance and biocompatibility, among many other properties, is crucial, especially in modern engineering and material science industries. This is influenced by the demand for high-performing and more efficient materials in biomedical, aerospace, and automotive engineering, as well as in other engineering sectors where such materials are required. However, it is challenging to attain such materials, and this has raised the attention of numerous research studies in composite and nanocomposite materials. Composite materials are formed as the result of combining two or more distinct materials to yield advanced materials with properties that are entirely different from the original materials. This paper investigates the effects of reinforcing High-Density polyethylene (HDPE) with Multi-Walled Carbon Nanotubes (MWCNT) nanoparticles at weight fractions of 0, 0.5, 1, and 1.5 wt.%. In this paper, only the elastic properties of the HDPE were evaluated at these different weight fractions. The results show that a weight fraction of 1 wt.% of MWCNTs nanoparticles offered the best reinforcement for HDPE/MWCNT nanocomposites among the investigated weight fractions.

Authors: Bhore Chaitanya V. , Andhare Atul B. , Padole Pramod M.
Published: August 2023

Due to exponential growth in solar photovoltaic technology and power generation, it is common to see solar PV modules mounted on structures subjected to dynamic loading. These dynamic loads such as wind, rain, snow, base excitation, transportation and much more causes vibrations in the PV modules and deteriorate their performance. Among the various dynamic loads, Base Excitation is one of the major cause for induced vibration in PV modules. Vibration amplitude and frequency were preciously recorded at the base/mounting of PV module in the vicinity of Metro Rail. From the vibration reading it was observed that the peak frequency levels fall in 30-80 Hz range. Therefore, for harmonic response analysis of PV module it was necessary to build a shaker table which will provide the required base excitation for analysis. This paper deals with design, modelling, assembly and finite element modal and harmonic analysis of shaker table. Shaker table is divided in basic four parts, 1) base, 2) spring support, 3) electric motor with unbalanced mass and 4) mounting structure for PV module mounting. Variable speed electric motor is attached with a disc with different holes at varying distance from the center of the shaft, so as to provide multiple types of harmonic forces and frequencies. Before manufacturing, modal and harmonic analysis is performed on the shaker table plus PV module assembly in ANSYS to check whether the systems natural frequency comes near to only PV modules modal frequency range. It was observed that the shaker table natural frequencies were not in the range of PV module’s natural frequencies. This study will be useful to provide a basis for designing the clamping and mounting arrangements for the PV modules to retard its performance deterioration due to the induced vibrations.
PID parameter tables after ITAE to control overshooting systems found with AI algorithm
Authors: Roland Büchi
Published: August 2023

Embedded controllers are used in many applications. It often happens that these do not offer any possibilities to set the controller parameters, because they are capsulated to outside. The closed-loop systems are then stable, but the systems are often weakly damped and their step responses exhibit overshoot. In the following, a method is described, how such embedded controlled systems can be controlled via a superimposed feedback loop using PID controllers in such a way that the system deviation of the step response is minimized according to the ITAE method. A method from artificial intelligence, hill climbing, is used for this purpose. For the control of such systems, the paper essentially provides PID controller parameters, which are usable for many weakly damped systems. The parameters are verified in a practical application with a speed control of a motor with inertial mass.

Published: August 2023

Electric vehicle adoption is being promoted as a major counteract to mitigate vehicular pollution. This calls for improvement of technologies to enhance the reliability and safety of electric vehicles (EV). The battery pack of an EV being its major component needs to be monitored properly in every charge-discharge cycle as it is subjected to different drive profiles in terms of current flowing through them. Battery Management System (BMS) considers the dynamic parameters of the pack and performs various functionalities which are helpful for the safekeeping of vehicles as well as users. State of Charge (SoC) estimation is an important function that helps BMS to monitor deterioration in charge available in cell. This paper implements the state of art techniques on an accurate Enhanced Self-Correcting model of Li-ion cell which considers dynamics and hysteresis profile observed in cell subjected to drive cycles. This paper describes three approaches i.e. EKF, SPKF and Bar delta algorithms for SoC estimation. Case studies and comparison of all the techniques are presented.
Parametric Optimization of Friction Stir Welding (FSW) of Dissimilar Aluminum Alloys with Newly Developed Tool
Authors: Sharma Nikita , Singh Anuraj
Published: August 2023

Semantic Image Inpainting is a challenging and promising research problem where parts of an image are masked or corrupted and need to be filled based on the semantic and visual information available from the image. Image Inpainting can help revive ancient scriptures, paintings, and recover corrupted parts of images without the guidance of a subject matter expert. Existing computer vision techniques using neighborhood based gap filling provide unsatisfactory results. In this paper, a novel visual feature learning model driven by context-based pixel prediction is employed, which develops the missing part of the image by conditioning on the available data. We adopt a Generative model based approach to derive inference about the missing part of the image from the context of the entire image. A novel loss function based on the linear combination of generative loss and contextual loss provides promising results for semantic image inpainting. Experiments on datasets show that our method successfully predicts information in large missing regions and achieves pixel-level photorealism.

Quality Assurance (QA) is required to ensure precision in the vehicle Assembly Unit process. The most significant challenge is that manual work is error-prone, and even minor errors can be a problem for a vehicle. This study aims to explore suitable Deep Learning (DL) models to automate various parts of the task well. For the current work, the aim is focused on predicting/detecting points on the chassis accurately. In this article, we elaborated on the process to generate the dataset and the proposed model 'You Look Only Once-v5' (YOLOv5) to identify cross marks on the vehicles. The model architecture and parameters are discussed in-depth and changed to detect and classify marked objects against the chassis background. The accuracy and efficiency evaluations show that the model achieved the top performance in average precision (mAP) of ≥ 98%.

To teach eMobility to bachelor students, a development project was set-up, to be undertaken by students. The aim is to explore the various aspects of eMobility by practical laboratory tasks. In the first phase of the project, an eKart was assembled. In this phase of the project, the electronic controls are implemented. To finally implement drive-by-wire in an eKart, the speed controls, communication and the drivers-display, are implemented in a single steering wheel. Communication with the speed controller and the battery management system, has to be included in this steering wheel. By implementing all controls, communication as well as the drivers display inside a single steering wheel, simplifies the final eKart design. Communication via a single SPI interface reduced the wiring inside the eKart and allows easier exchange during maintenance or upgrades.

Authors: Mukundan Arvind , Tsao Yu-Ming , Wang Hsiang-Chen
Published: August 2023

In this work, a mobile and relatively inexpensive housing device based on hyperspectral imaging (HSI) has been developed. In addition to a touchscreen, a light-emitting diode lighting system (LED) with a dimmer, a Raspberry Pi 4 central processing unit (CPU), and a Raspberry Pi camera were all included into the module. A visible HSI (VIS-HSI) method was developed that could create an HSI image from any RGB image taken by the Raspberry Pi camera. A near-infrared (NIR) camera and the NIR-HSI method, which was created to determine the spectral reflectance between the wavelengths of 780 and 2500 nm, may be used in lieu of the Raspberry Pi camera. The fact that this idea does not need the use of a second decoding key is among the most significant advantages it offers, along with its low cost, small size, lack of moving parts, and absence of any other prerequisites.

Authors: Farrokhian A. , Zarei M.S. , Kolahchi R.
Published: August 2023

The dynamic stability response of micro functionally graded materials (FGM) porous beam is studied. The structural damping is expected using Kelvin-Voigt theory. The microbeam is placed on the viscoelastic foundation with spring, shear and damper constants. The size influences are expected based on the couple stress theory with one length scale material factor. The Timoshenko theory for microbeam is employed for the governing final equation on the basis of Hamilton’s principle. The final motion couled equations are attained by differential quadrature method (DQM) for calculating the dynamic stability area. The influences of various components of FG index, porosity, geometric and structural components for the microbeam on the dynamic response of the structure are exposed. It is obvious that with enhancing the porosity value, the dynamic instabillity region (DIR) shifts to higher frequencies.
Comparing the Economic and Environmental Compatibility of Battery Electric and Conventional Vehicles in India

Published: August 2023

Conventional vehicle fuel resources are encompassed with the jeopardy of being scarce; eventually exacerbating fuel prices. This high fuel prices further aggregate to elevate the total ownership cost and have led to an epiphany of national energy security. Further, the emission from conventional fuel combustion urges a need to cogitate about the already saddled environmental concerns. Alternatively, electric vehicles are looked upon as a potential option to conventional vehicles due to no tail-pipe emissions and low operating costs. However, if a complete life cycle is considered, an intuitive assumption that electric vehicles have no emissions and costs less can be a deception. Hence, the feasibility of electric vehicles as an option for conventional vehicles needs to be contemplated in economic and environmental aspects. This article presents the comparison between battery electric vehicles and conventional vehicles by performing a life cycle analysis (economic and environmental) in the Indian context. A Total Cost of Ownership (TCO) model is developed for financial analysis to depict the compatibility status of battery electric vehicles. The environmental analysis is conducted by using OpenLCA software based on ReCePi 2016 method for all the impact categories at mid-point as well as end-point levels. The results reckon electric vehicles are costlier than conventional vehicles with current statistics and policies in India. However, by implementing certain optimizing parameters in sensitivity analysis, electric vehicles are found to have cost parity and even become more economical than conventional vehicles in some cases. The outcomes from environmental analysis unveil that the GHG emissions from battery electric vehicles are less than that from conventional vehicles. However, out of the 18 impact categories considered, battery electric vehicles have less impact in 10 categories and even have less impact score at the end-point level.
Reduction of Antimicrobial Formation on HVAC Water Cooling Towers using Chromium Oxide (Cr2O3) Coating
Authors: Almushref F.R. , Aldossary Turky M.
Published: August 2023

Nearly all buildings employ a cooling tower as part of their heating, ventilation, and air conditioning (HVAC) system. Water is used in an HVAC system's heat-transfer process. The Occupational Safety and Health Administration (OSHA) has mandated that HVAC systems must be cleaned twice a year in order to prevent pneumatic infections. In particular, photocatalytic coatings, which are hydrophobic and antibacterial, are used to meet the harsh environment requirements at the microscale. In this study, water cooling tower coating systems were employed to test their efficacy. Stainless steel made up the samples. The samples had chromium oxide (Cr2O3) as the base coating and varying thicknesses of ytterbium oxide (Yb2O3) on top. To guarantee that the samples in the model had enough water around them and the necessary airflow to keep them from always being submerged, samples were placed in a water splash zone. For six months, the samples were left alone. Also, to evaluate the various effects, some samples were left in the shade while others were left in the sun.
Static Configurations of Clamped Hybrid Bistable Symmetric Laminates
Authors: Hijazi Sara , Emam Samir
Published: August 2023

This paper presents an examination of symmetric laminates that exhibit two stable states in response to changes in temperature with clamped boundary conditions. To ensure resistance to losing their bistability when affixed to bigger structures or clamped, hybrid laminates are used. The laminate’s bistability is triggered by symmetrically embedded bidirectional glass-epoxy layers (BD). The analysis employs an approximate analytical model based on the Rayleigh-Ritz approach. The BD layers have a significant impact on the laminate’s shape at room temperature. The research explores the effect of varying the geometric parameters of the BD layers, specifically their thickness and location from the laminate’s center. In the second part of the study, a new design for a bistable wing is proposed, which combines a flat symmetric platform with a modified hybrid symmetric bistable laminate that acts as a bistable winglet.

Analysis of statistical interpolation methods to generate the velocities model for continental Ecuador from GNSS data
Authors: Luna Marcos , Staller Alejandra , Tierra Alfonso , Molina Xavier , Toulkeridis Theofilos
Published: August 2023

We performed a comparison between the interpolation methods of Kriging and Least Squares Collocation. This allowed to obtain an optimal velocity model of the earth’s crust for continental Ecuador from a velocity field ITRF2008 obtained with GNSS data in the period 2008-2014. The best fitting semivariograms for the two components were the Spherical and Stable semivariogram. The functional model for Least Squares Collocation method was of third order for the East component and of second order for the North component. The results obtained were compared with the velocity of the GNSS stations used for verification and using the cross-validation technique. All the statistics favor the least squares Collocation method since it presents a better fit and reliability to represent the velocity model of continental Ecuador.
El concepto de sociedad civil: una reflexión geográfica/rizomática
Authors: Figueroa Esteban
Published: August 2023

Se reflexionó sobre el concepto sociedad civil en algunas escuelas de geografía en Chile, qué entendemos de él, sus alcances y límites. Así, abordamos una discusión necesaria sobre un concepto ampliamente utilizado en las ciencias sociales, con extensa presencia en la literatura geográfica; sin embargo, en esta su estudio explícito hasta ahora ha sido limitado. La investigación se centró en una propuesta metodológica exclusivamente cualitativa. De ella, se utilizaron las técnicas de análisis cualitativo de contenido y una adaptación a la técnica Delphi en su consulta a expertos. Se evidenció que no hay propósito explícito en los usos del concepto de sociedad civil, no obstante, se debe al poco conocimiento de este; a su vez hay una afirmación generalizada de que es significativo para los estudios geográficos, por ello la importancia de construirlo desde la Geografía.

Authors: Rodríguez Kirvi , Briceño Emilio , Amador Humberto , Melgar-Domínguez Ozy D.
Published: August 2023

Introducción. La tendencia mundial apunta al uso de vehículos eléctricos (VEs) y conlleva a la necesidad de realizar estudios para estimar la capacidad de las redes de distribución al incorporar estas nuevas cargas. El objetivo de este trabajo fue analizar el posible impacto de la conexión de VEs a una red de distribución de baja tensión en Honduras.  Métodos. Se obtuvo información de consumos energéticos de los abonados y características de las líneas de distribución entre otros, utilizando datos de una red de baja tensión. Con la representación de una red de distribución de baja tensión, se analizó el posible crecimiento tanto en el consumo energético como en los picos de potencia debido a la conexión de VEs, estimando el incremento de la demanda con respecto a la capacidad instalada de la red. Se capturaron diferentes patrones de conducción, los cuales definieron la energía requerida para ser cargados y el horario de conexión y desconexión. Dicho impacto fue evaluado mediante un análisis de flujo de potencia cuando se alcanzaron picos de consumo. Resultados. Basado en los resultados obtenidos en la simulación, se observó que cuando se alcanzó una penetración de VEs de 50%, límites técnicos, como ser límites mínimos de tensión, podrían verse negativamente impactados. Conclusión. A medida la integración de VEs incremente en la red de distribución será necesario repotenciar la red eléctrica para suplir las nuevas necesidades de la demanda.

Published: August 2023

Menjadi orang-orang kristiani tidak hanya menjalankan ritual keagamaan secara ketat dan detail serta mengejawantahkan tuntutan keagamaan secara individual maupun komunal.  Satu hal yang membuat orang-orang kristiani menjadi semakin ‘serani’, menjadi sungguh Katolik, pengikut Yesus adalah menjadi murid bagi Sang Guru, Yesus Kristus di dalam dunia yang diwarnai oleh keragaman agama. Kajian kualitatif berbasis studi pustaka ini  menyelisik ‘kemuridan sejati’ orang-orang kristiani zaman sekarang dengan belajar pada murid-murid Sang Guru di tanah Palestina duaribu tahun silam sebagai jalan untuk menegaskan jati diri ‘ecclesia’ yang melekat dalam diri orang-orang kristiani di hadapan kenyataan multireligius. Kajian ini menemukan bahwa ‘kemuridan sejati’ orang-orang kristiani dan jati diri ‘ecclesia’ yang melekat dalam diri orang-orang kristiani merupakan modal sosio-religi bagi pengikut Kristus dalam mengimplementasikan jalinan relasional yang kohesif dan membangun komunitas kemanusiaan dengan kaum beragama-beriman yang lain. Kemuridan sejati orang-orang kristiani dan jati diri ‘ecclesia’ menjadi basis epistemologi kehidupan yang dialogis di tengah kenyataan multireligius. Kajian ini diharapkan menyumbang bagi khazanah keilmuan di bidang pastoral dan humaniora.

Migrant parents’ contributions to students’ negotiations of their educational futures: A case study at a Norwegian high school
Authors: Melnikova Julia
Published: August 2023

The educational futures students aspire to and make specific choices in shaping are formed in the encounter between school practices and family dispositions. More research is needed to understand whether and how migrant parents are invited to contribute to high school students’ negotiation of these possible futures. Drawing on observations and interviews with students and parents from a single-school case study, this article explores how migrant parents contribute to students’ decision making. Seen through a Bourdieusian lens, the logic of the high school education field sets boundaries around what is regarded as feasible and valuable parental involvement. Parents are experienced as acting indirectly through hints and suggestions. The study indicates that providing guidance is complicated by expectations of student autonomy. The findings warrant further research on school parental involvement practices that can support students’ negotiation of possible futures.

Motor vehicle theft from year to year always increases, both when parked and while being driven. Data from the National Police Headquarters for the period 1 to 7 May 2022 recorded 118 cases, and increased to 309 cases in the period 8 May to 14 May 2022. Based on the problem with the increase in motorized vehicle theft, a system is needed that can protect motorized vehicles from these theft cases. In this article we propose an additional system for electronic motorized vehicles. This system consists of additional controls, namely an e-KTP and touch screen, while the switch for the front brake already exists in motorized vehicles. After the ignition is turned on, the driver must press the touch screen button, press the front brake, attach the e-KTP to the RFId reader, each maximum time span for 50 seconds. If it is not in the sequence and the time is more than 50 seconds it will cause the motorized vehicle's horn to sound. After connecting, making controls and testing, the control system can work perfectly..

This research paper presents the report on the study of polyurethane foam (PU foam) to produce lightweight geopolymer composite. In this study, fly ash (FA) for 70% and powdered coating sludge (PCS) for 30 % used as source were activated by alkaline activator NaOH 14 M and Na2SiO3 mixture with the ratio Na2SiO3/NaOH of 2.0 and samples were cured at 80°C for 4 hours, stored at room temperature for 7, 14 and 28 days. The impact of adding PU foam particles, ranging in size from 2 to 4 mm, to FA/PCS-based geopolymers with a solid content of 0 to 50% has been studied. It was discovered that the amount of PU foam particles added caused the compressive strength and density of the lightweight geopolymer composite to decrease. Although the compressive strength was decreased when the amount of PU foam was increased but it is still be the standard of block lightweight concrete.   Therefore, it is indicated that PU foam is one of the viable alternatives for reinforcement in the creation of lightweight geopolymer composites.

One approach to significantly enhance hotel products, services, and marketing strategies is through online guest evaluations. However, few research has examined online reviews utilizing a SERVQUAL model for sentiment analysis, therefore addressing this gap, notably in the Philippine hotel industry. The SERVQUAL model, which was modified in accordance with the purpose of the study, served as the foundation for the framework. Customers who had stayed at and evaluated the establishment on Agoda, Kayak, and Booking Web Portal served as subjects, and Qualitative Sentiment Analysis Research design was used. The results were divided into positive and negative sentiments and categorized using the five RATER (Reliability, Assurance, Tangibles, Empathy, and Responsiveness) dimensions of service quality. The validity and reliability of the instruments used can be attributed to the literature utilizing and validating them as a measurement scale of customer satisfaction. Finally, the study revealed that the overall satisfaction of guests at the hotel establishment was heavily influenced by physical hotel features rather than intangible factors. The researchers were then able to provide specific suggestions for improving the hotel service and product quality, as well as prospective program improvements which can also be used by other accommodation.

Theme parks have grown in popularity around the world, not only because they are a popular source of major amusement, but also because they are a stress-relieving destination for both children and adults. At Walt Disney World, there are four different and unique destinations: EPCOT, Animal Kingdom, Hollywood Studios, and the Magic Kingdom, which is the most popular of the three. This qualitative study aims to acquire information from secondary data gathered from various YouTube vlogs in order to assist researchers in determining the elements that influence tourists' desire to return to Walt Disney World's Magic Kingdom Theme Park. Simultaneously, establish what strategies might be offered and developed to aid tourists' desire to return to the stated park, and other theme parks. Through content analysis, a qualitative research approach was employed to examine tourists' experiences, perceptions, and statements. In addition, data extraction employed a purposive sample strategy, with the YouTube videos (vlogs) from second-time or more visits to Walt Disney World's Magic Kingdom theme park. The study concludes that the image of the destination, level of happiness that tourists have with the site, infrastructure, natural and cultural surroundings, level of safety and security, and price, are all key elements that can greatly impact visitors' intents to return to a theme park. Several recommendations are then made for other theme and amusement parks to improve tourists’ intention to return.

Published: August 2023

Background: Worldwide, inguinal hernia repair is the commonest surgical procedure in general surgery, but the optimal repair technique for inguinal hernia has not been defined and accepted in most parts of Africa and other developing nations. The aim of this study was to determine the epidemiology of inguinal hernias and feasibility of mesh implants in our centre.Methodology: This was a descriptive crosssectional study of consecutive adult patients with uncomplicated inguinal hernias who received polypropylene mesh for repair of their inguinal hernias. Selection criteria included inguinoscrotal/ inguinolabial hernia, recurrent or bilateral hernia or bubunoceles with wide defects. Descriptive statistics and tests of significance were done.Results: Inguinal hernia represented 77.3% of all abdominal wall hernias encountered during the study. However, only 27.8% (100 patients) of the 360 patients that satisfied the inclusion criteria received mesh implants. Of the 100 patients studied, 31% had recurrent hernias, 48% harbored complete inguinoscrotal/inguinolabial hernia while 13% had incomplete inguinoscrotal hernia. Majority (86%) had unilateral hernia. The annual repair rates using mesh implants increased progressively from 4% in 2013 to 40% in 2017. A quarter (25%) had comorbidities. Majority (60%) of repairs were under general anesthesia. The overall postoperative complication rate was 14%. Wound infection rate was 3.5%. There was statistically significant difference in the rates of wound-related events between recurrent and primary inguinal hernias (p=0.000). There was no mortality or recurrence recorded in this study.Conclusion: The uptake of mesh implants for inguinal hernia repair in our environment is low, though the trend is changing with higher proportions of patients accepting mesh implants in recent time. Elective inguinal hernia surgery with polypropylenemesh is feasible, safe, effective and reproducible in our setting.

Background: Road traffic injuries (RTI) are a major public health problem and contribute significantly to the global burden. The aim of this study was to assess the frequency of RTIs in children and to determine their socio-demographic and lesional characteristics.Patients and methods: This was a retrospective and descriptive study over a two-year period from January 2015 to December 2016 conducted at the Department of Paediatric Surgery at the Aristide Le Dantec Hospital in Dakar. Included were all children under the age of 16 victims of a RTI. We studied various parameters relating to the victims (sex, age, education) and the accident (location andtime of occurrence of the accident, circumstances and mechanism, duration of admission to the emergency unit, localization and type of lesion). The data was entered and processed using Microsoft Office Word and Excel 2010 software.Results:Among the 425 cases received, 62.6% were boys and 37.4% girls. The average age of the children was 7.7 years. RTIs occurred mainly in pedestrian (63.8%) who wanted to cross the road. There were more accidents in the city-center area (64.9%) and during afternoons (61%). Lesions of the soft parts (wounds, contusion and decay) were predominated (89.6%) followed by fractures. Theupper limbs were the main locations of trauma.Conclusion: RTIs are common among children in Dakar. Boys crossing roads are the largest number of victims. Soft tissue trauma predominates and is mainly found on the thoracic limbs.
