Published: January 2024

Many Vulnerable Road Users (VRUs) experience injuries and fatalities every year, making road safety a challenge in the World. According to the Ministry of Road Transport and Highway (MoRTH) during the year 2021, a total number of 4,12,432 road accidents have been reported in India, claiming 1,53,972 lives and causing injuries to 3,84,448 persons. In terms of road-user categories, the total fatality of the Pedestrian road-users was 18.9 per cent of persons killed in road accidents.

One of the ways to handle the situation is to protect pedestrians utilizing active safety measures in the vehicle. In addition, active safety research heavily relies on perceptions of pre-crash scenarios. The objective of the study is to examine passenger car-to-pedestrian scenarios and model active safety system in a car to prevent or mitigate collisions.

Road Accident Sampling System – India (RASSI) database is used for this research, which provided a comprehensive set of accident data describing the interaction between the vehicle, the environment and the pedestrian. RASSI has collected in depth information of more than 6000 cases from the year 2011 in India. From RASSI database, query was performed for car-to-pedestrian accident from the year 2019 to 2022. After querying, 48 cases were considered for the study. The study solely considers cars, thus pertinent information on the location of the pedestrian in relation to the vehicle and the time before impact is gathered using the accident reconstructions available in RASSI.

The study is conducted in two parts. Firstly, the study focuses on identifying the optimum Field-Of-View (FOV) for a stereo camera sensor for Pedestrian detection. The second part of the study uses the data from the FOV study to model active safety system and evaluate its effectiveness on the queried scenarios collected from RASSI in PC-Crash. Proposed active safety system shows the promise for future work related to developing active safety system for car-to-pedestrian scenarios in India.

Published: January 2024

An Inertial Measurement Unit (IMU) provides vehicle acceleration that can be used in Active Vehicle Safety Systems (AVSSs). However, the signal output from an IMU is affected by changes in its position in the vehicle and alignment, which may lead to degradation in AVSS performance. Investigators have employed physics and data-based models for countering the impact of sensor misalignment, and the effects of gravity on acceleration measurements. While physics-based methods utilize parameters varying dynamically with vehicle motion, data-based methods require an extensive number of parameters making them computationally expensive. These factors make the above-explored methods practically challenging to implement on production vehicles. This study considers a 6-axis IMU and evaluates its impact on Antilock Braking System (ABS) performance by considering the IMU signal obtained with different mounting orientations, and positions on a Heavy Commercial Road Vehicle (HCRV). It then develops a computationally effective transformation that requires only two parameters for compensating the IMU sensor mis-orientation and extracting vehicle acceleration from the IMU signal. This transformation also provides physical intuition on the sensor mis-orientation for gauging the vehicle’s dynamic characteristics. Subsequently, a Kalman filter is utilized to estimate the unresolved offset in longitudinal acceleration. The IMU calibration combined with an ABS algorithm was evaluated in a Hardware-in-Loop experimental setup using IPG TruckMaker®. Improvements in longitudinal acceleration estimates by 94-98% were achieved with the calibration algorithm, when compared to the unprocessed IMU data. Moreover, the processed longitudinal acceleration estimates significantly enhanced wheel slip estimation performance by over 60% for a majority of the test cases, avoiding critical problems of wheel lock, and zero brake torque before the vehicle reaches its crawling speed. The outcomes of this study are expected to contribute as a critical block in the development of an indigenous ABS solution for HCRVs.

Published: January 2024

Good driving practices, encompassing actions like maintaining smooth acceleration, sustaining a consistent speed, and avoiding aggressive maneuvers, can yield several benefits. These practices enhance energy efficiency, reduce accident risks, and significantly lower maintenance costs. Consequently, the presence of a system capable of providing actionable insights to promote such driving behavior is crucial.

Addressing this need, the Drive-GPT model is introduced, representing an AI-based generative pre-trained transformer. Within this study, the transformative potential of deep learning networks, specifically based on transformers, is showcased in capturing the typical driving patterns exhibited by individuals in diverse road, traffic, weather, and vehicle health scenarios. The model's training dataset comprises an extensive 90 million data points from multivariate time series originating from telematics systems in 100 vehicles traversing eight distinct Indian cities over a six-month span.

These pre-trained models offer substantial utility for downstream applications, including the computation of driving scores, generation of driving recommendations, and the classification of driving behavior as either proficient or suboptimal. The performance evaluation on test data indicates commendable results, with a coefficient of determination (R-squared) of 0.98 and a root mean square error (RMSE) of 0.0346. Furthermore, a discernible differentiation emerges in terms of energy efficiency and regenerative braking between good and suboptimal driving behaviors. Notably, this differentiation leads to a notable 25% improvement in energy efficiency and an 18% enhancement in regenerative capabilities.

Driver safety has become an important aspect. To have driver safety RADAR is an essential part of vehicles hence RADAR has great significance in the automotive industry. The Radar sensor collects data from surroundings that may have unwanted data that may lead to improper detections of intended objects, so to have proper object detections it is needed to use clustering methods on the radar point cloud data. There are numerous unsupervised clustering methods used for RADAR applications. In this paper, the comparisons of different unsupervised algorithms such as K-Means Clustering, Hierarchical Clustering, Cluster Using the Gaussian Mixture Model, and DBSCAN are presented. All these clustering algorithms are evaluated based on various evaluation criteria such as the Silhouette coefficient, Davies Bouldin index, etc. Based on evaluations and comparative studies applications of the clustering algorithms are classified.
A Traffic Microsimulation Based Study of an Electric Road System with Dynamic Wireless Power Transfer
Authors: Sardar Arghya , Prasad Mukti
Published: January 2024

Electrification of road transport is a critical step towards establishment of a sustainable transport ecosystem. However, a major hindrance to electric mobility is the high cost and weight of the battery pack. Downsizing the battery pack will not only address these issues, but will also reduce embedded emissions due to battery manufacturing. One approach towards reducing battery pack size and still offering the user of electric vehicles similar mobility experiences as in case of conventional vehicles is to set up extensive network of charging or battery swapping stations.

Another approach is to provide the vehicle with required energy while it is on the move. However, conventional systems such as overhead line or conducting rails have several disadvantages in the urban environment. One solution that has come up in this regard in recent times is the concept of Electric Roads System (ERS), which involves dynamic wireless power transfer (DWPT) to the vehicles from power transmitters embedded in the road they are driving on. The vehicles using ERS can have a downsized battery pack to enable it run on segments without ERS.

Major advantage of the ERS are reductions in the cost of the battery pack and charging time. The vehicles also have reduced energy consumption due to reduction in mass.

In this paper, an ERS is simulated using traffic microsimulation tool Simulation of Urban Mobility (SUMO) with heterogenous traffic. Effect of vehicle speed on charging of battery is considered. Based on the simulation results, impacts of such a system on the traffic flow and the electric power supply system are studied. The variation of the state of charge of the battery pack of the vehicles is also studied.

Published: January 2024

The automotive industry has seen accelerating demand for electrified transportation. While the complexity of conventional ICE vehicles has increased, the powertrain still largely consists of a mechanical system. In contrast, vehicle architectures in electrified transportation are a complex integration of power electronics, batteries, control units, and software. This shift in system architecture impacts the entire organization during new product development, with increased focus on high power electronic components, energy management strategies, and complex algorithm development. Additionally, product development impact extends beyond the vehicle and impacts charging networks, electrical infrastructure, and communication protocols. The complex interaction between systems has a significant impact on vehicle safety, development timeline, scope, and cost. A systems engineering approach, with emphasis on requirements definition and traceability, helps ensure decomposition of top level requirement for subsystem development as well as compatibility between systems. This paper addresses common methodologies and tools within the systems engineering discipline to overcome integration complexity for the E-Mobility sector. Focal points of the systems engineering discipline, including architecture, requirement definition, and integration, are examined in the context of overall product lifecycle. Impact on functional safety is a key consideration, which is integrated into every phase of product development in accordance with ISO 26262. Systems engineering is an essential role for integration of subsystem and component level activities into a coherent framework using the V-model for product development.
Effect of Spot Weld Parameter on HAZ of Advanced High Strength Steel Joint
Authors: Jain Vikas , Misal Swapnali , Paliwal Lokesh
Published: January 2024

To meet different target of light-weighting, lower fuel economy, crash safety and emission requirement, advanced high strength steel (AHSS) is commonly used in automotive vehicles and has become popular now a days. AHSS material up-to 1500 MPa is commonly used for structural components and major reinforcement of automotive BIW. Manufacturing of AHSS material requires precise control of chemical composition, and subsequent rolling and heat treatment to get optimum combination of required phases In most of the AHSS material microstructure, martensite is present along with ferrite or other phases. Hot stamp steel with strength level 1500 MPa strength also have martensite phase in microstructure after press hardening. However during heating and cooling cycle in resistance spot welding, martensite phase tempering affects hardness at Heat Affected Zone (HAZ). Softness at HAZ lower downs shear and tensile strength of joint which impacts fatigue properties of the joint and energy absorption during vehicle crash. Base material and spot weld joint’s fatigue strength and energy absorption at high strain rate are two important properties and performance criteria. These are generally considered while designing automotive parts and their joining. This paper discusses HAZ softening while spot welding of AHSS, impact of weld parameters (welding current, weld time, electrode force) on microstructure, micro-hardness and derivation of optimum spot weld parameter for spot welding with AHSS material.
Drivetrain Pressure Spike Evaluation Methodology & Optimization: Simulation and Testing Correlation
Authors: Memane Nilesh , Kumar Suneel , Veerkar Vikrant
Published: January 2024

This paper presents a virtual analysis method for pressure spike estimation and optimization of hydraulic system architecture for off-highway applications with hydraulically actuated clutch. This pressure spike leads to a very high torque spike in driveline components during clutch pop-up conditions in puddling operations. These torque spikes lead to potential failure of driveline components i.e., gear, shaft, bearing and torsional damper during sudden engagement events. To assess the hydraulic system performance during clutch pop-up cornering conditions is very challenging and leads to compromise on operator safety in the paddy field. It is essential to develop a simulation methodology in a virtual environment to understand the system behavior during clutch pop-up condition and impact of various hydraulic system parameters. This paper describes a Model Based System Design (MBSD) approach for understanding hydraulic system pressure spike phenomenon and dynamic response. Pressure spike simulation methodology was established using 1-D approach with the right fidelity modeling to capture the transient events. This model includes hydraulic clutch actuation system, clutch Pedal linkages, torsional damper, drivetrain & vehicle inertia. This method has been compared with test data attained on tractor during puddling operation in the field. This method helps to identify and predict the severity of pressure spike during early phase of product development cycle for investigation & optimization of hydraulic system design. DOE was performed to investigate the impact of hydraulic system components like valves, accumulator on pressure spike and its impact on drivetrain components. This analytical method is helping to resolve the design issue in the early phase of product development cycle in shorter period and thus leads to overall reduction in product development cycle time, cost and risk associated with field test operations.

The Indian automotive industry is striving towards more safe and durable vehicles. A need was felt to study the effect of changes in axle static loads on fatigue life of the axle components. Also, there was a need to develop generic test method, as there are no test standards or generic methods available in public domain for fatigue testing of commercial vehicle axles. The study was carried out to check direct effect of change in axle loads on various connections on axle, effect of suspension configuration and force distribution, Vehicle dynamics, etc.

In this paper, an India specific generic load spectra was evaluated for accelerated laboratory validation. Paper discusses the methodology as; study of heavy commercial vehicle systems, road load data collection on identified test vehicles w.r.t. test matrix finalized, India specific test loads and load spectra development, normalization of axle load spectra w.r.t to static axle weights and arriving at test guidelines. Comprehensive experiments and load measurements were carried out on test vehicles to arrive at a generic test methodology and test cycles. The derived test specifications were correlated with current industry practices and the actual in-lab experiments were conducted.
A New Holistic Approach for System-Level Development of Seat Features
Authors: Ghosh Soumik , Vidhu Nandagopal
Published: January 2024

System engineering-based approach is now ubiquitous in the automotive industry. It is a disciplined approach that ensures that targets are clearly defined and met through a structured and holistic approach. In this paper, we report an application of a systems engineering-based methodology for developing seating system features. It starts with a Business Requirement Document (BRD), which enlists the business requirements of a feature. We then developed a Logical Architecture Diagram (LAD) on a Simulink environment, which is an initial proposal for designing the logic to realize the desired functionality. As a next step, we perform Functional Failure Analysis (FFA) on the LAD to identify potential failure modes. We propose a few ways to mitigate the identified failures or modify the design so that these failures are rendered inconsequential to the end user. Based on the updated LAD, a System Requirement Document (SRD) is created, which contains all the requirements corresponding to the logic present in the LAD. Once the SRD has been prepared, the system-level test cases are created to validate each requirement on the system-level test rig, i.e., Hardware-in-Loop (HIL) rig. These test cases are authored using Keyword Driven Testing (KDT) methodology. The test cases are exhaustive to ensure that all the business requirements in the BRD are met. This approach offers multiple benefits, including a considerable reduction in failures at the test stage, re-usability of test cases across the vehicle programs, reduced development time, and satisfying the needs of all internal stakeholders.

Published: January 2024

Choice and consumption of food is affected by a range of factors and dietary choices can change over time at both an individual and population level. One behaviour to have changed over the last few years is the purchasing of plant-based foods. UK sales of meat-free and plant-based dairy products have roughly doubled between 2016 and 2020 and in 2020 were worth close to £600m each (Glotz, 2021; Wunsch, 2021). Food Standards Agency (FSA) data from 2022 found that 32% of respondents reported eating meat alternatives in the past, although the majority (66%) are not eating them frequently (Armstrong et al, 2022). Reflecting this, the consumption of red meat and pre-cooked meat has gradually fallen (Fuller et al., 2019). In 2021, 41% of respondents in an FSA survey said that they would like to eat less meat (Heard and Bogdan, 2021)￼ In the context of increased sales of plant-based foods, the study aimed to identify the impact of an annual plant-based meal campaign- ‘Plant-Forward’- conducted in cafeterias serviced by a large UK catering company. The campaign sought to influence consumer food choices by: 1) increasing the availability of plant-based meals to customers in a workplace cafeteria and 2) making plant-based meals more salient and attractive to consumers by using promotional materials. This included claims regarding health and sustainability of plant-based foods in general and newly-launched plant-based meals. The study also aimed to determine the duration and speed of the deterioration of any significant treatment effect identified. To our knowledge, this is the first study to evaluate such campaigns which look at immediate as well as long-term effects in a cafeteria setting.
Analysis and Investigation of the Naming of the Silk Road Based on Economic Geography
Authors: YAWAR Mohammad Ekram , SHARIFY Abdul Jamıl
Published: January 2024

The road that is known as silk today has been the longest and one of the most used trade routes throughout the history of East. A large part of this road, which connected the westernmost regions of China to the easternmost shores of the Mediterranean, passed through Great Khorasan (from Qoms to Jayhun).In the 19th century, in European studies, the name "Silk Road" was used for this road and soon it became popular. Even today, everyone, from the east and the west, knows and calls this historical road by the same name. This naming is due to the fact that according to these researchers, silk was the main and most important commodity that was exchanged along the road.In this research, the question of correctness or incorrectness of this naming has been investigated. Based on the findings of this research, this naming cannot be based on historical and objective facts for two main reasons.The first is that until before the 19th century, none of the Islamic, Afghan and Iranian geographical sources mentioned the name of silk, and most of it was called "Khorasan Road". It has been mentioned and the second is that the study of economic geography and traded goods was carried out. Look, it shows that silk is only one of the hundreds of traded goods and has no special advantage over other goods.

In the new studies of international relations, culture; Application and importance have been found. This issue has made the clash of cultures unavoidable, especially in the era of globalization, when national borders are collapsing and the government's rule is under the influence of the technological revolution. Therefore, culture, values and industrial products, all of them have found political use today. The foreign policy apparatus of the governments are trying to create a positive, acceptable and attractive face for the world community by using cultural diplomacy. Cultural diplomacy helps countries to implement their international and domestic programs; Because in this way, the behavior and policies of the governments are justified and acceptable. In this article, an attempt has been made to examine the extent of cultural diplomacy in Afghanistan's foreign policy. The main question is where is the position of cultural diplomacy in Afghanistan's foreign policy? The findings of his research, using the descriptive-analytical method, show that the Ministry of Foreign Affairs of the country did not pay much attention to cultural diplomatic tools and did not use the media, civil society, and scholarships. Also, the country's tourism potential has been neglected.
US Foreign Policy Towards Afghanistan. Brief from 2001 to 2022
Authors: Akbari Mohammad Qasim
Published: January 2024

In 2021, U.S. and international forces departed after nearly two decades of operations in
Afghanistan; the internationally backed Afghan government and its military forces collapsed; and the
Taliban, that formerly ruled the country from 1996 to 2001, retook power. The aftershocks of these
events continue to reverberate within Afghanistan, throughout its region, and in the United States as
publics and policymakers alike grapple with the reality of the Taliban’s renewed rule. When the United
States, in response to the terrorist attacks of September 11, 2001, led a military campaign against Al
Qaeda and the Afghan Taliban government that harbored and supported it. In the subsequent 20 years,
the United States suffered over 22,000 military casualties (including about 2,400 fatalities) in
Afghanistan, mostly at the hands of the robust and growing Taliban insurgency, and Congress
appropriated approximately $144 billion for reconstruction and security forces there. At the same time,
an elected Afghan government replaced the Taliban and, with significant U.S. and international support,
made limited improvements in most measures of human development. This article examines the policy
and strategies of the U.S in Afghanistan

Aims. Osteoarthritis is a degenerative and progressive disease characterized by abrasion of joint cartilage and irregular formation of new bone on the surface of the joints. Pain becomes the main symptom followed by a decrease in joint range of motion, causing disability and interfering with daily activities. The purpose of this study was to determine the effect of osteoarthritis exercise on pain and joint range of motion in osteoarthritis patients. Methods. The research design used a quasy experiment with a non-equivalent control group design approach. The sample used was 70 respondents for each intervention group and control group. Intervention in the form of physical exercise osteoarthritis exercise guided by an instructor and using audio-visual media. Exercise is carried out 3 times a week for 2 weeks. For stretching and flexibility exercises using yoga mats and bath towels and for strength building exercises using chairs. The pain scale was measured with a numeric rating scale (NRS) instrument and measurement of joint range of motion using a goniometer. Data analysis used numerical comparative analytic paired-sample t test and independent t test. Findings. The results showed that the results of the paired t test (p) <0.05. thus indicating that there is an effect of providing osteoarthritis gymnastics training intervention on reducing the pain scale. The results of the paired t test (p) <0.05. thus indicating that there is an effect of providing osteoarthritis exercise training interventions on the scale of joint range of motion. The results of the independent t test (p) <0.05, meaning that there is a difference in the osteoarthritis pain scale before and after the intervention, while the test for differences in joint range of motion scale shows a non-significant value of p> 0.05. Conclusion. The conclusion of the study was that there was an effect of osteoarthritis gymnastics training in reducing the osteoarthritis pain scale and joint range of motion scale. Then there is no difference between the control group and the intervention group who get gymnastic exercises and do not get osteoarthritis gymnastic exercises.

Motherhood is a period there is a deconstruction of one identity and reconstruction of another, including changes in self-concept, commitment, and learning. For athletes who become mothers, these changes also occur and impact in their career. We aim to describe the experience of being pregnant for a group of Brazilian athletes, understanding the impact of maternity on the career and the postpartum for these women. A qualitative descriptive and exploratory study was conducted followed the guideline Standards for Reporting Qualitative Research (SRQR). We are using the semi-structured interviews with nine Brazilian athletes all of whom were professional athletes at the time they became pregnant. Maximum Variation Sampling and the snowball technique were used. The analysis was done using Iramuteq software, which performed Descending Hierarchical Classification (DHC) and Similarity Analysis. The nine athletes had a mean age of 38.3 years (SD: 5.5 years), from different levels and sports, and all had at least one child. We identified 488 text segments, which resulted in two branches, divided into five classes: History in sport (class 2); Pregnancy planning and immediate postpartum (class 5); reconciling the routines of athlete and mother (class 3); Social support narrative (class 4); Childcare (class 1). The findings indicate that athletes can have emotional ga ins in reconcile motherhood with their sports careers to the extent that they have social support, relative planning to become pregnant, and reconcile their athletic routine with baby care.

“Quarto de despejo: diário de uma favelada” de Carolina Maria de Jesus: análise discursivo-crítica dos gêneros discursivos em articulações
Authors:   , Neves Carolina Zorzal
Published: January 2024

A presente pesquisa tem como objetivo problematizar como os gêneros discursivos prefácio, diário e entrevista articulam-se discursivamente na edição popular de Quarto de Despejo: diário de uma favelada (1962). Para isso, utilizamos o método relacional-dialético e transformacional de análise de discurso crítica tal como desenvolvido por Lilie Chouliaraki; Norman Fairclough (1999), com foco na construção do Significado Acional (FAIRCLOUGH, 2003). Outrossim, nos valemos da Teoria Interseccional, do Pensamento Feminista Negro afro- americano (COLLINS, 2017, 2019; DAVIS, 2016; hooks, 1995, 2014, 2018, 2019) e de intelectuais pretas brasileiras (CARNEIRO, 2003, 2005, 2020; EVARISTO, 2005; GONZALEZ, 1982, 1984, 2020; RIBEIRO, 2017). A partir da análise, observamos um agenciamento discursivo e político de Audálio Dantas nos gêneros diário e prefácio, este o primeiro a ser lido, influenciando a leitura da obra como um todo. Ademais, as funções sociais que os gêneros prefácio e entrevista assumem na prática social analisada ressaltam o eixo temático do sucesso mercadológico do livro, sem validar o potencial literário da escritora – que foi exposta a críticas questionando a sua capacidade intelectual e o seu poder criativo. Identificamos, também, a temática da literatura como resistência e fuga para Carolina, que, enquanto escritora de literatura brasileira, mãe, mulher, preta, potente, inteligente e lírica, se tornou inspiração para outras mulheres pretas e resistiu à visão eurocêntrica do cânone literário. Assim, consideramos que os gêneros discursivos em articulação (re)produzem e mantêm práticas hegemônicas racistas, sexistas e classistas, construindo relações assimétricas de poder que atravessam o corpo e os discursos potencialmente ideológicos sobre Carolina Maria de Jesus.

Published: January 2024

The influence of the traditional method of storing potato varieties, namely Gala, Colombo, Red Scarlett, grown in the Southern Federal District, on its biotechnological potential was studied. It was determined that in the tubers of the Gala varieties the dry matter content was – 25.20%, in Red Scarlett – 22.6%, the ratio of protein and starch in the tubers of the Gala varieties (1: 11.1) and Red Scarlett (1: 10.7), which indicated their good technological properties. The Colomba variety had a dry matter content below 20%, and the protein to starch ratio also had a lower value (1: 9.3). Protein losses during storage amounted to, in varieties of , in%, Gala – 7.5; Colomba – 9.2; Red Scarlett – 4.9; starch loss – 10.9; 8.8; 17.8 respectively. The mass fraction of reducing sugars decreased in all potato varieties, in%: Gala – by 39.4; Colomba – at 67.7; Red Scarlett – at 55.0. The loss of vitamin C during storage was, in varietiesof, in% Gala – 23.8; Colomba – 26.8; Red Scarlett – 33.3. It was determined that potato tubers contained a level of nitrates that was acceptable for food raw materials and food products, while their content decreases during storage. Nitrate losses were, in varieties, in%, of Gala 57.1; Colomba 49.0; Red Scarlett 54.6. Changes in the physical and chemical properties of potatoes after storage indicate the preservation of the biotechnological potential of the raw material and the possibility of its use in public catering establishments. The Gala variety of potatoes is universal for processing in catering establishments; it is suitable for use in dishes (boiled, fried, baked), preparing multifunctional semi-finished products (for salads, soups), chips, crispy potatoes, etc.

Maximum Power Point Tracking Achievements and Challenges in Photovoltaic Systems
Authors: Mousa Ahmed
Published: January 2024

The ever-increasing demand for electrical energy in recent decades has necessitated the exploration of alternative energy sources, one of which is solar energy. The most practical means of utilizing solar energy is through the use of a Photovoltaic (PV) system. Nevertheless, the energy harvested by PV modules is constrained by low conversion efficiency, nonlinearity, and susceptibility to weather conditions, such as temperature and irradiance levels. To address these limitations, Maximum Power Point Tracking (MPPT) techniques have been developed to optimize the output of PV systems under specific circumstances. This academic article provides an in-depth analysis of the most widely used MPPT techniques, utilizing both traditional and soft computing methods. The article discusses the fundamental principles and practical applications of these techniques, as well as the challenges associated with MPPT, such as coping with rapidly changing irradiance and partial shading scenarios.

Fiber optic networks currently have a lot of interest, so a network monitoring system is needed that guarantees quality and speed of repair if mass disruption occurs. in research [1] regarding fiber network damage detection using IoT with the use of a 1:4 splitter and the use of a detector that can work at a wavelength of 650nm so that it can detect damaged cables with output in the software. So in connection with this, the author wants to develop the results of this research by using a 1:8 splitter and carrying out detection using the LDR sensor and NodeMCU ESP32 using IoT (Internet of Things) technology. The ESP32 NodeMCU will receive data in the form of light intensity values ??at each ODC from the LDR sensor. And then sent to a database that is connected directly to the Android application. The cable identification process occurs in three states: normal, warning, and error. The test and analysis results show that the hardware device can work well, with attenuation in the passive splitter cable of 10.28 dB and a light source with a wavelength of 650 nm. Cable detected as damaged is indicated by an output in the software with a delay of 4.56 s.

Published: January 2024

Macrobending is a form of disturbance in Fiber To The Home (FTTH) networks that occurs due to macro-level bending of the cable caused by damage to the fiber optic. Macrobending frequently occurs in FTTH networks within the feeder cables. Feeder cables serve as connectors between the Optical Line Terminal (OLT) and Optical Distribution Cabinet (ODC) in the FTTH system. The occurrence of macrobending in feeder cables affects the quality of the FTTH network. In this study, the impact of macrobending is analyzed based on curvature diameters of 50 cm, 25 cm, and 5 cm on feeder cables before and after FTTH network activation. Before FTTH network activation, the High Super Luminescent Diode (HSL) is used as the input power source, whereas after activation, the input power source comes from the OLT using Small Form-factor Pluggable (SFP) modules. The attenuation (loss) before activation due to macrobending, with curvature diameters of 50 cm, 25 cm, and 5 cm, is found to be 0.02 dB, 0.05 dB, and 0.26 dB, respectively. After activation, the attenuation with the same curvature diameters is measured as 0.01 dB, 0.02 dB, and 0.20 dB, respectively. It is observed that as the curvature diameter decreases, the attenuation increases. The comparison of attenuation before and after network activation doesn't show a significant difference because the input power doesn't affect macrobending, rather it is influenced by the curvature diameter.

Published: January 2024

Maize drying is a crucial procedure in the agricultural and food industries, aimed at decreasing the moisture content of maize kernels to prolong their shelf life, inhibit microbial growth and maintain their quality. Two common methods for drying corn include natural techniques, which involve drying the maize in the sun, and artificial techniques, where specialized equipment such as hot air dryers, drum dryers and microwaves are employed. The author constructed a corn dryer utilizing Arduino. This device employs heat elements and fans to expedite the corn drying process. The tool can significantly quicken the corn drying process. The author utilises a DHT22 sensor to gauge temperature and humidity levels of the corn. The device is capable of generating temperatures ranging from 20?C to 90?C, thanks to the assistance of the DHT22 sensor during the drying process.
