A Low-Cost System for Road Induced Tire Cavity Noise Control (RTNC)
Authors: Sues Micha , Nojavan Aidin , Kirchhof Jan , Schirmacher Rolf
Published: June 2024

The transition from ICE to electric power trains in new vehicles along with the application of advanced active and passive noise reduction solutions has intensified the perception of noise sources not directly linked to the propulsion system. This includes road noise as amplified by the tire cavity resonance. This resonance mainly depends on tire geometry, gas temperature inside the tire and vehicle speed and is increasingly audible for larger wheels and heavier vehicles, as they are typical for current electrical SUV designs. Active technologies can be applied to significantly reduce narrow band tire cavity noise with low costs and minimal weight increase. Like ANC systems for ICE powertrains, they make use of the audio system in the vehicle. In this paper, a novel low-cost system for road induced tire cavity noise control (RTNC) is presented that reduces the tire cavity resonance noise inside a car cabin. The approach is cheap in terms of computational effort (likewise ICE order cancellation) as well as additional hardware components. The signal from only one single-axis-accelerometer is used to estimate the frequency of the tire cavity resonance in real time. The sensor position is chosen to achieve a high signal to noise ratio (SNR) for the resonance which leads to a robust frequency estimation but does not require specific high coherence with interior noise components. The interior microphones and speakers of the vehicle are used to control the narrow-band noise at the estimated frequency. The performance of the system is investigated based on the simulation results as well as measurements in a real vehicle. The results match well and demonstrate that the technology is well understood, allowing potential virtual system tuning based on reliable simulation data. The system shows a high global reduction of the cavity noise in the vehicle's interior.

Published: June 2024

By building on mature internal combustion engine (ICE) hardware combined with dedicated hydrogen (H2) technology, the H2-ICE has excellent potential to accelerate CO2 reduction. H2-ICE concepts can therefore contribute to realizing the climate targets in an acceptable timeframe. In the landscape of H2-ICE concepts, pilot-ignited High Pressure Direct Injection (HPDI™) is an attractive option considering its high thermal efficiency, wide load range and its applicability to on-road as well as off-road heavy-duty equipment. Still, H2-HPDI is characterized by diffusion combustion, giving rise to significant NOx emissions. In this paper, the potential of H2-HPDI toward compliance with future emissions legislation is explored on a 1.8L single-cylinder research engine. With tests on multiple load-speed points, Exhaust Gas Recirculation (EGR) was shown to be an effective measure for reducing engine-out NOx, although at the cost of a few efficiency points. Furthermore, the use of EGR was compared to water injection in the intake port. Water injection displayed a substantially weaker NOx reduction sensitivity, owing in part to a relatively low injection pressure applied in these tests, causing poor water atomization and evaporation. Finally, injection timing sweeps showed that the gross indicated thermal efficiency (ITE) still approached or surpassed 50% for most load-speed points with EGR. At higher loads, where peak pressures constraint the injection advance, ITE was lowest. While further development steps are necessary to ensure compliance, this work demonstrates that H2-HPDI has good potential for meeting upcoming NOx legislative levels, with a potential ITE comparable to, or perhaps even better than, that of modern diesel engines.

Hydrogen engines are currently considered as a viable solution to preserve the internal combustion engine (ICE) as a power unit for vehicle propulsion. In particular, lean-burn gasoline Spark-Ignition (SI) engines have been a major subject of investigations, due to their reduced emission levels and high thermodynamic efficiency. Lean charge is suitable for the purpose of passenger car applications, where the demand of mid/low power output does not require an excessive amount of air to be delivered by the turbocharging unit, but can difficulty be tailored in the field of high performance engine, where the air mass delivered would require oversized turbocharging systems or more complex charging solutions. For this reason, the range of feeding conditions near the stochiometric value is explored in the field of high performance engines, leading to the consequent issue of abatement of pollutant emissions. In this work a 1D model is applied to the modeling of a V8 engine fueled with direct injection (DI) of hydrogen. The engine has been derived by a gasoline configuration and adapted to hydrogen in such a way to keep the same performance. The lambda condition has been chosen as a best compromise between performances and emissions, focusing onto a single cylinder configuration. The calibration of the engine has been performed onto this single cylinder configuration, tailoring the same power output and delivering the air mass flow imposing the desired boost pressure to match the desired engine torque. Then, the 1D schematic of a V8 engine has been built, based on the developed single cylinder and the air delivery system configured to satisfy the required air mass flow rate. Three different test cycles have been investigated (one WLTP and two RDEs) with different driving conditions. The after treatment system has been consequently sized to guarantee the abatement of NOx and the pollutant emissions analyzed showing different scenarios that can be adopted for this kind of engines, guaranteeing the reduced level of pollutant emissions and keeping the desired performance and fun of drive.

Published: June 2024

Traditional CACC systems utilize inter-vehicle wireless communication to maintain minimal yet safe inter-vehicle distances, thereby improving traffic efficiency. However, introducing communication delays generates system uncertainties that jeopardize string stability, a crucial requirement for robust CACC performance. To address these issues, we introduce a decentralized model predictive control (MPC) approach that incorporates Kalman filters and state predictors to counteract the uncertainties posed by noise and communication delays. We validate our approach through MATLAB/Simulink simulations, using stochastic and mathematical models to capture vehicular dynamics, Wi-Fi communication errors, and sensor noises. In addition, we explore the application of a reinforcement learning (RL)-based algorithm to compare its merits and limitations against our decentralized MPC controller, considering factors like feasibility and reliability.

Published: June 2024

A major issue of battery electric vehicles (BEV) is optimizing driving range and energy consumption. Under actual driving, transient thermal and electrical performance changes could deteriorate the battery cells and pack. These performances can be investigated and controlled efficiently with a thermal management system (TMS) via model-based development. A complete battery pack contains multiple cells, bricks, and modules with numerous coolant pipes and flow channels. However, such an early modeling stage requires detailed cell geometry and specifications to estimate the thermal and electrochemical energies of the cell, module, and pack. To capture the dynamic performance changes of the LIB pack under real driving cycles, the thermal energy flow between the pack and its TMS must be well predicted. This study presents a BTMS model development and validation method for a 75-kWh battery pack used in mass-production, mid-size battery SUV under WLTC. Eighty thermocouples, pressure, and coolant flow sensors are installed on the different battery cells, bricks, and modules to capture the time-series thermal and electrical performance changes. The dual e-motor vehicle is tested on a chassis dynamometer to measure transient pressure drop, inlet-outlet coolant temperature, battery pack and brick temperature, and voltage. These data are used to validate the integrated battery pack and its TMS cooling circuit. The pack model consists of 4416 cells based on 2RC branches equivalent-circuit model (ECM) calibrated using an electrochemical Pseudo 2D approach. The integrated BTMS model includes all inlet and outlet cooling flow channels to validate its thermal and electrical performance under steady-state and WLTC tests. The total model can capture dynamic performance changes, such as pack and brick temperature, pressure drop, and voltage, with over 90% accuracy. The model can be used in complete vehicle model simulation with low computation time and high accuracy for future VTMS studies.

Published: June 2024

This study explores the feasibility of using a sustainable lignin-based fuel, consisting of 44 % lignin, 50 % ethanol, and 6 % water, in conventional compression ignition (CI) marine engines. Through experimental evaluations on a modified small-bore CI engine, we identified the primary challenges associated with lignin-based fuel, including engine startup and shutdown issues due to solvent evaporation and lignin solidification inside the fuel system, and deposit formation on cylinder walls leading to piston ring seizure. To address these issues, we developed a fuel switching system transitioning from lignin-based fuel to cleaning fuel with 85 vol% of acetone, 10 vol% of water and 5 vol% of ignition improving additive, effectively preventing system clogs. Additionally, optimizing injection parameters, adopting a constant pressure delivery valve, and fine-tuning injection timing mitigated lignin deposit formation related to incomplete combustion or spray tip penetration to the cylinder wall. The successful combustion of the lignin-based fuel in the small-bored CI engine was confirmed in a wide range of chamber temperatures. The ignition delay was measured and analyzed using Arrhenius equation. The ignition quality of the lignin fuel was comparable with 1-pentanol with a cetane number of 18.2, which is acceptable for 2-stroke marine engines. Although further investigation is needed to assess long-term reliability, our findings underscore the potential of lignin-based fuel as a viable alternative fuel for marine engines.

Authors: Akpomedaye Ogaga , Odoh Friday , Juwah Helen
Published: June 2024

This study explored the impact of organic soil stabilizing agent on the engineering behaviors of subsoil commonly used for engineering applications in Nigeria. The soil obtained from a borrow pit and air-dried under laboratory conditions (30±5oC and 81±7% relative humidity). The dried soil sample was stabilized with rice husk ash (RHA) at the rate of 2, 4, 6, 8 and 10% (by mass of the soil) and cured for 14 days under natural conditions. A J-band microwave at a frequency of 7.0 GHz was used to measure the dielectric properties, while the standard proctor compaction test was used to determine the maximum dry density “MDD” and optimal moisture content “OMC” of the soil samples. Results obtained from the study depicted that the RHA had a significant effect on both the electrical properties of the soil. It was noted from the findings that, as the quantity of RHA used in stabilizing the soil increased from 0 to 10%, MDD values declined non-linearly from 1.61-1.42 g/cm3, while the OMC values inclined in a non-linear pattern from 14.8 - 17.1%. Similarly, the study results indicated that the soil dielectric constant and loss increased from 3.41 to 5.13 and 0.91 to 1.44 respectively, as the RHA incorporated into the soil raised by 10%. Present findings offer valuable insights into the fields of civil and electrical engineering, especially in the context of soil treatment for engineering applications.

Authors: Ghonimy Mohamed , Suliman Ahmed , Morsy Mohamed , Abdel-atty Ahmed , Alzoheıry Ahmed
Published: June 2024

Rice straw stands out as the primary agricultural residue posing significant challenges for both farmers and the Egyptian government. Its volume accounts for approximately 18% of the total annual waste generated. Livestock farmers typically harvest the straw and feed it to their animals. However, the process of manually mixing molasses, urea, and salts with the straw often leads to inconsistent blending and uneven distribution of the mixture. This inconsistency poses a considerable risk to the health of the animals, potentially resulting in fatalities. Thus, a mechanical system for producing animal feed (rice straw cutting mixed with additives of urea, minerals and molasses) was developed. This system consists of a chopping unit, mixing unit, and pumping & distribution unit. Measurements included the uniformity of the cut rice straw pieces within the preferred size, the uniformity of the dissolved additives mixture and the uniformity of the additives distribution on cut rice straw. Crude protein and urea percentages were measured in the final product. The results showed a maximum production rate of 0.6 ton h-1 the suitability of the developed system for mixing the additives with the cut rice straw. The suitability of the developed system was determined through the uniformity of the distribution of the additives on the cut rice straw. The results showed that the optimum content of crude protein of 6.2% was found at urea content of 5% and a mixing unit shaft speed of 300 rpm and 5 min mixing time. Also, the developed system achieved a rate of return of 19% and a payback period of about two years.
UNDERSTANDING AGNI IN AYURVEDA – A CRITICAL REVIEW STUDY
Authors: Sukkur M Abdul , S Sarath. , K Pradeep
Published: June 2024

Background - Agni is considered an essential factor in the Paka process. The food assimilated should transform into some form to be easily absorbed to maintain life. Agni is understood in terms of types according to location and functions performed. But it should be comprehended as one only and the understanding of Agni can be at the Bhoota level, Dosha level, Dhatu level, Mala level, and so on. The metabolism process is mainly due to the different levels of Agni influencing Prasada and Kitta proportions. Also, the impairment of the proper function-ing of Agni is considered the prime cause of Sama condition. Aim – To do a literary study on different aspects of Agni. Objective – To determine Agni's significance in the body based on the available literature. Methods - A review study has been conducted based on the available literary resources from the institutional library. Discus-sion – Agni is the primary factor in the proper metabolism of food consumed and, thus, in turn, maintaining an individual's health. Sama condition in the body is observed due to improper functioning at different levels of Ag-ni. Conclusion – The cause of all diseases is said to be improper metabolism, which can be understood as im-pairment in Agni. The improper Agni levels, if continued, will manifest Amavisha, which is a lethal condition that ultimately harms the life of an individual. So, proper knowledge of Agni is essential to maintaining health and curing a disease.
SYMPTOMATIC RELIEF AND IMPROVED QUALITY OF LIFE IN A PATIENT WITH MITRAL VALVE PROLAPSE AND SEVERE MITRAL REGURGITATION FOLLOWING AYURVEDIC INTERVENTION- A CASE REPORT
Authors: Narendran K Nimisha , V G Mini
Published: June 2024

Mitral Valve Prolapse (MVP) relates to unique mechanical abnormalities in the mitral valve apparatus and adjacent
myocardium. MVP is a relatively common finding in the general population, and it is associated with ventricular
tachycardia and sudden cardiac death. In severe cases, surgical intervention such as mitral valve replacement or
repair is deemed appropriate. However, in this case report, we present a patient with MVP who experienced remarkable alleviation of symptoms and improved quality of life after undergoing Ayurvedic intervention. In the
context of MVP, Ayurveda considers Vata Pradhana Tridoshas a potential underlying cause leading to structural
and functional abnormalities in the heart. The intervention here typically involves the Vatavyadhi Chikitsa Sutra,
Swasam Chikitsa and Rasayana to restore the Amsa-amsa Dosha Avastha imbalance. The treatment is tailored to
the patient's Prakriti and manifested Dosha-Dhatu malfunctioning. This study highlights the potential benefits of
Ayurvedic intervention in managing symptoms and enhancing the quality of life in patients with MVP with severe
mitral regurgitation.

CHARACTERISTICS OF THE MANIFESTATION AND EXHIBITION OF MUAY TAY ATHLETE’S STRESS RESISTANCE AND SELF-CONTROL BEHAVIOR
Authors: Stepanyan Anahit , Nadoyan Anna
Published: June 2024

Abstract
The article is dedicated to the modern developmental problems of sport psychology.Nowdays the life of individuals  is related to stress and stress resistance, which are reflected in everyday life, including sports. Learning successful ways to deal with stress is extremely important for an athlete. Sport (sporting activity) is inherently stressful  for elite and novice Thai boxers,both of  them  equally exposed to stress during training and competition and need appropriate psychological support[2;8].
Almost every Thai boxer is in a state of high or pronounced stress. At the same time, men and women are equally susceptible to stress during sports activities. Such athletes widely use several self-supporting behavior strategies during their activities to cope with stress moreover, most of them reach a high level of expressiveness. In the work, an attempt was made to reveal the characteristics of the manifestation of stress resistance and self-control behavior formation of Muay Thai athletes, to study the mutual relationship between stress resistance and self-control behavior and the characteristics of behavior formation and manifestation.
An experimental study was organized to study the manifestation of stress resistance of athletes of the mentioned sport [1]. Observations, testing and data processing methods were used for the studies, as a result very important conclusions were made. Various manifestations of stress resistance and self-control behavior among Thai boxers were revealed in the studied groups. In athletes, a high tension was observed in the self-monitoring behavior of positive reappraisal and seeking social support. This can be said to characterize Thai boxers as individuals who are focused on the personal, philosophical, reinterpretation of the problematic situation and are included in the broader context of the individual's self-development work. Perception of social support also indicates athletes' focus on interaction with other people, their support, attention, advice, sympathy, and expectation of concrete effective help. The dominant self-control behavior stress behavioral strategies of athletes are distraction and social distraction from the problem. An indicator of the level of neuropsychological stability or stress resistance is negatively correlated with self-control behavior strategies of taking responsibility and planning for problem solving, as well as problem solving strategies.

Concrete, due to its inherent brittleness, exhibits relatively low tensile strength. Fibers have been used extensively to improve their mechanical properties as they helped to reduce the crack width. Textile industries produce a lot of natural and synthetic fiber waste, which can be utilized to produce better-performing fiber-reinforced concrete. Therefore, in this study, a detailed experimental investigation has been carried out to study the compressive, tensile, and flexural properties of the Kevlar and jute fiber reinforced concrete. Concrete specimens with a mix design ratio of 1:1.43:1.89 and a water-cement ratio of 0.6 were cast. Jute fibers with lengths of 10 mm, 15 mm, and 25 mm and three different concentrations of 0.1%, 0.25%, and 0.5% by volume of concrete were used. In contrast, Kevlar fibers with lengths of 10 mm, 15 mm, and 20 mm and three different concentrations of 1%, 1.5%, and 2.5% by volume of concrete were used. It was found that both Kevlar and Jute fibers contributed positively to- wards controlling the crack initiation and propagation, suggesting using fibers in concrete for enhanced mechanical properties and performance.

O exame citopatológico do colo uterino, obtido através do esfregaço e leitura morfológica das células, tem por objetivo detectar precocemente o câncer cervical, terceiro tipo de câncer mais incidente no Brasil. O exame é preconizado para mulheres entre 25 e 64 anos de idade, que já tiveram ou possuem vida sexual ativa, por se tratar de um grupo propenso a desenvolver lesões de alto grau. Entretanto, existem diversos desafios que dificultam o acesso das mulheres ao exame preventivo. Objetivo: Relatar a experiência percebida durante a realização da consulta de enfermagem ginecológica, destacando as ações desenvolvidas durante a coleta do preventivo e seus desafios, vivenciados em diferentes contextos sociais. Metodologia: Trata-se de estudo descritivo, de abordagem qualitativa, no formato relato de experiência. Resultados e discussões: As consultas de enfermagem ginecológica são realizadas inicialmente por meio de anamnese, com intuito de obter o histórico pessoal, familiar, ginecológico e obstétrico das pacientes. Entre os desafios encontrados para efetivação da consulta de enfermagem ginecológica, destacam-se a falta de adesão e de conhecimento por parte das usuárias sobre a importância, periodicidade e público-alvo para realização do exame citopatológico. Considerações finais: O enfermeiro tem papel fundamental na busca ativa, promoção de saúde, educação em saúde, sensibilização do público-alvo e identificação da população de risco. Espera-se que as temáticas abordadas neste artigo, vivenciados pelos residentes de enfermagem, sirvam para outros profissionais da Atenção Primária em Saúde, ampliar o conhecimento sobre o relevante papel do enfermeiro no rastreamento do câncer de colo uterino.
