Lubrication Evaluation of EV Transmission
Authors: Kushwaha Rakesh , Bhosale Vikas , Navale Pradeep , Patel Hiral
Published: January 2024

Advent of EV powertrain has considerable effect on transmission development activities as competed to regular ICE transmission. Conventional ICE transmission and the transmission for an e-powertrain differ on fundamental level. The conventional transmission has number of gear ratios, shift mechanism which enables the transmission to deliver a smooth power output as per demand from the driver. Whereas the e-powertrain transmission is mostly a single gear ratio transmission (reducer) which primarily depends on speed and torque variation from the motor to cater the driver requirement. Hence, the operating speeds of such e-transmissions can vary from 0 to 20000 rpm in both forward and reverse directions. Such a large speed variation as compared with conventional transmission calls for special attention towards the lubrication of internal components. High speeds and lower oil viscosities tend to disrupt the oil films in between contact surfaces causing metal to metal contact. This situation aggravates the wear and tear of the mechanical components such as gears, bearings etc. This paper describes the test methodology developed to ensure and evaluate the lubrication performance of the transmission. This paper takes into account the various operating conditions in terms of temperature, gradient, direction of rotation, loading conditions to derive test conditions. Paper also gives details of trials carried out on e-transmission to arrive at optimum lubricating oil quantity for performance and durability. The methodology described in this paper can be used for single and multispeed EV transmission.

Published: January 2024

The need for effective control systems is exacerbated by tighter pollution regulations and consumer demands for highly efficiently vehicles especially in the passenger segment. The air flow estimation of engine and accordingly controlling the fuel removes the lacuna of modern gasoline engines. The hot wire type mass air flow sensor is commonly used for air flow measurement, and it generally mounted in clean side piping to prevent damage to air mass flow sensor. The right estimation of air flow is possible by getting uniform flow over the different engine operating speed and load conditions. The placement of air flow sensor becomes critical considering the engine layout and packaging constraints and meeting the sensor mounting requirements. The deviation in mounting of air flow sensor will lead to consequently impact of engine performance and emissions.

In our new developed air intake system for passenger vehicle application, torque oscillations were observed over engine operating speeds and load conditions. The air flow oscillations and signal were further evaluated to understand issue. The detail study of air flow signal was carried out over different engine operating range with air filter box layouts. In this paper, extensive work were carried out to understand impact of air flow signal variation. The different air intake layout were evaluated along with sensor mounting to minimize signal disturbance to get proper estimation of air flow. The detailed study with final air intake system was finally evaluated. Boodanur, R., Panwar, A., Kulkarni, S., and Jadhav, A. [1] described the Air Intake System Optimization for Passenger Car Engine.

Published: January 2024

India has recently shifted from BSVI 1.0 emissions norms to BSVI 2.0 RDE (Real Drive Emission) norms ready with implementation of conformity factors for the measurement of on-road emissions. The discrepancies between emission values measured in the laboratory (under controlled ambient conditions) and actual emission values on the road (under real driving conditions) will be reduced with the implementation of BSVI 2.0.

Fuel impacts the vehicular tail pipe emission in a greater way and various regulated emission pollutants are reduced significantly. Government initiated fuel formulations like oxygenated fuels (E10 & E20) and OMCs (IOCL) initiated differentiated diesel fuels plays significant role in achieving the targets for real driving emissions. Current study was performed on BSVI gasoline port fuel injection vehicle, gasoline direct injection vehicle and diesel vehicle on RDE compliant route (Faridabad specific – route formulated by Indian Oil R&D Centre) with different set of test fuels as per IRDE BS6 2.0 (Indian Real Drive Emissions) norms. The on-road emissions data was generated with AVL make RDE PEMS equipment (Portable Emission Measurement System) along with post processing of the collected data as per RDE test procedure.

The test vehicle was driven on-road as per RDE compliant route & boundary conditions and conformity factors were calculated in each case for CO & NOx pollutants. Reference CO2 values were measured on standard regulatory legislative test cycle i.e., Modified Indian Driving Cycle on chassis dynamometer. Distance specific as well as CO2 window specific emissions were measured during the whole RDE trip and the RDE test passed with all fuel formulations and significant reduction was observed in major regulated tail pipe emissions. The study supports the fact that various novel fuel formulations can support the automotive OEM’s in meeting the stricter RDE emission regulation in terms achieving the better conformity factors for the emitted tail pipe emission.

Published: January 2024

Task-Oriented Training (TOT) is an proven stroke rehabilitation intervention with significant evidence-based research that supports its effectiveness. The absence of a clear definition has led to variability in research reporting and subsequent confusion with practical implementation. A consistent definition seeks to remedy this ambiguity to facilitate knowledge translation. The objective of this study was to determine a comprehensive definition of TOT that encapsulates previous definitions and descriptions in the literature. In order to derive this definition, a two stage scoping review process was conducted across four databases searching for articles on the use of TOT in adult stroke rehabilitation therapy.

The analysis of this scoping review included 174 articles. Commonly found words used to define TOT included: repetitive, functional, task practice, task specific, task oriented, intensity, and client-centered. Other salient words that aligned with the principles of neuroplasticity and key components of TOT were meaningful, progressive, graded, variable, and feedback. Based on these findings, a comprehensive proposed definition is as follows: Task-oriented training is an effective stroke rehabilitation intervention that focuses on the use of client-centered, repetitive practice of activities that are of high intensity and meaningful to the client. In conclusion, although similar principles were described in the TOT literature, there was no consistent and comprehensive definition of TOT. This scoping review identified key concepts from TOT methodology, and discussion sections in rehabilitation literature to generate a proposed comprehensive definition of TOT to guide research and practice.

One may argue that linezolid was the pioneer among the oxazolidinone antibiotics. This chemical is an antibiotic that has been synthesised. It binds to rRNA and stops bacteria from making proteins. Additionally, it slows down the pace of translation elongation reactions and prevents the formation of the initiation complex during protein synthesis, both of which shorten the produced peptide chains. A number of infections have been approved for treatment with linezolid, including those caused by vancomycin-resistant Enterococcus faecium, Staphylococcus aureus pneumoniae in hospitals, complicated SSSIs, uncomplicated SSSIs caused by methicillin-susceptible S. aureus or Streptococcus pyogenes, and Streptococcus pneumoniae in community settings.

Authors: Bello Rotimi-Williams , Oladipo Mojisola Abosede
Published: January 2024

Conventional method of counting animals is one of the most challenging tasks in livestock management; moreover, counting of animals in drone-acquired imagery, though promising, is more challenging in intelligent livestock management. In this paper, we apply state-of-the-art object detection model, Mask YOLOv7, for detection and counting of cattle in different scenarios such as in controlled (feedlot) environment and uncontrolled (open-range) environment. Mask mechanism was embedded into the backbone of the YOLOv7 algorithm (Mask YOLOv7) for instance segmentation of individual cattle object. We evaluate the performance of the model proposed in this study using Intersection over Union threshold of 0.5, average precision (AP), and mean average precision. The results of the experiment conducted in this study show that the proposed model achieves an accuracy of 93% in counting cattle in controlled environment and 95% in uncontrolled environment. These results affirm the potential of the model, Mask YOLOv7, to perform competitively with any other existing object detection and instance segmentation models in terms of accuracy and AP especially when the speed of object detection matters. Moreover, the research has potential applications in livestock inventory, which helps in tracking, monitoring, and reporting vital information about individual cattle.

Introdução: a hanseníase é uma doença in fecciosa crônica causada pelo Mycobacterium leprae (M. leprae), um parasita intracelular obrigatório. Assim, a resistência do hospedeiro a esse patógeno depende da imunidade celular. O uso de modelos experimentais tem permitido o estudo da hanseníase do ponto de vista imunológico, microbiológico e terapêutico, entretanto, as diferenças na progressão da infecção entre os modelos mais empregados (camundongos imunocompetentes, BALB/c, e camundongos congenitamente atímicos, nude) são pouco estudadas. Objetivo: comparar a evolução da infecção pelo M. leprae em camundongos BALB/c e nude quanto à multiplicação bacilar e avaliação do perfil inflamatório sistêmico pela quantificação sérica de citocinas e óxido nítrico (NO). Métodos: os camundongos foram inoculados com M. leprae nos coxins plantares e avaliados aos 3, 5 e 8 meses após a infecção. Resultados: camundongos nude apresentaram multiplicação bacilar progressiva nos coxins plantares. Em camundongos BALB/c, o número de bacilos foi maior aos 5 meses. Em relação à quantificação de citocinas, nos camundongos BALB/c houve aumento de IL-2 e IL-17A e diminuição de IL-6 e NO aos 8 meses de inoculação. Nos camundongos nude, verificou-se o aumento do TNF aos 8 meses de inoculação e manutenção dos níveis de NO. Conclusão: os resultados encontrados sugerem que em camundongos BALB/c ocorre a ativação de uma resposta imune capaz de controlar a multiplicação do M. leprae, em contrapartida em camundongos nude a infecção é progressiva a despeito de altos níveis de TNF.

Quantifying the Impact of Risk Factors on Direct Compensation Property Damage in Canadian Automobile Insurance
Authors: Baylan Pervin , Demirel Neslihan
Published: January 2024

This study presents a statistical analysis assessing the impact of various risk factors on direct compensation property damage (DCPD) claims in private passenger vehicle accidents. Using automobile insurance data in Ontario, Canada for the decade years period between 2003 and 2012, a statistical model of property damage was explored via a generalized linear binary logit mixed model and considered the imbalance between the classes of insureds. The results indicate that several risk factors have a significant impact on the likelihood of DCPD claims, including usage, training, outstanding loss, and incurred loss. The effects of these risk factors were observed under the weights — the number of trials used to generate each success proportion — in the different classes of insureds. The generalized linear mixed models (GLMMs) analysis provides a powerful tool for quantifying the impact of risk factors on binary outcomes, which are called DCPD claims and property damage (PD) claims covered by third-party liability (TPL) insurance. These models can also inform insurance underwriting and policy design, focusing on identifying the most significant risk factors. The performance metrics calculated by considering the class imbalance in binary outcomes verify the resulting model’s ability to accurately predict classes. The F1 score, an evaluation metric to measure the performance of classification, was calculated as 0.934. In addition, PR AUC, which is the area under the Precision-Recall (PR) curve, was computed as 0.953. These high scores indicate that the resulting model performs well in the classification. The other metrics also support the classification accuracy of this model. The findings of the analysis can help insurers better understand the underlying drivers of property damages and develop more accurate and effective strategies for risk mitigation. Furthermore, this study highlights the importance of developing class-specific risk assessment models to account for the imbalance across different classes.

Published: January 2024

This paper explores the transformative potential of blockchain technology in addressing inefficiencies, opaque processes, and fraud susceptibility in the traditional supply chain ecosystem. Blockchain technology, with its distributed ledger technology (DLT), provides secure, transparent, and tamper-proof record-keeping capabilities throughout the supply chain. Its applications include traceability and transparency, inventory and logistics optimization, smart contracts for automated payments, and counterfeit prevention and brand protection. Blockchain's decentralized and immutable ledger facilitates traceability, offering an unalterable record of the journey of goods. Real-time visibility into inventory levels and locations empowers better forecasting, demand planning, and logistics management, leading to cost reductions and improved efficiency in warehousing, delivery routes, and resource utilization. Smart contracts enable automated, secure, and transparent execution of predefined contractual conditions, resulting in efficiency gains, cost savings, and contractual compliance. Blockchain also creates a secure digital fingerprint for products, combating counterfeiting and ensuring product authenticity throughout the supply chain. The case study of Everledger in the diamond industry exemplifies how blockchain technology contributes to ethical sourcing and reduces the risk of conflict diamonds. However, blockchain faces challenges such as scalability, regulatory uncertainties, cost, and privacy concerns. Future directions involve integrating blockchain with artificial intelligence and the Internet of Things, developing industry-specific blockchain solutions, and exploring hybrid blockchain models. By addressing these challenges through collaborative research, development, and policy initiatives, stakeholders can unlock the full potential of blockchain in supply chain management, creating a resilient and robust supply chain ecosystem.

O objetivo do estudo foi identificar os fatores preditores intrínsecos de quedas em idosos residentes em instituições de longa permanência. Trata-se de uma revisão integrativa da literatura, elaborada a partir das bases de dados: MEDLINE, LILACS, BDENF e IBECS, no mês de agosto de 2023. Os estudos foram selecionados por meio do diagrama de fluxo Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) e apresentados em um quadro. Foram selecionados 16 artigos, nos quais pode-se identificar os principais fatores desencadeantes para o risco de quedas em idosos institucionalizados. Dentre os achados, a avaliação da marcha e o equilíbrio foram evidenciadas como os maiores fatores desencadeantes de risco para quedas. Os resultados desta revisão integrativa da literatura levaram a concluir que as quedas são o incidente mais recorrente e com diversificados fatores de riscos, que podem impactar diretamente na qualidade de vida do idoso e de seus familiares. Evidencia-se ainda que para projetar medidas preventivas eficazes, se faz necessário determinar as circunstâncias associadas às quedas e promover um cuidado integral e multidimensional, considerando os diferentes contextos de vida do idoso.

Abstract. Clouds affect the Earth climate with an impact that depends on the cloud nature (solid and/or liquid water). Although the Antarctic climate is changing rapidly, cloud observations are sparse over Antarctica due to few ground stations and satellite observations. The Concordia station is located on the eastern Antarctic Plateau (75∘ S, 123∘ E; 3233 m above mean sea level), one of the driest and coldest places on Earth. We used observations of clouds, temperature, liquid water, and surface irradiance performed at Concordia during four austral summers (December 2018–2021) to analyse the link between liquid water and temperature and its impact on surface irradiance in the presence of supercooled liquid water (liquid water for temperature less than 0 ∘C) clouds (SLWCs). Our analysis shows that, within SLWCs, temperature logarithmically increases from −36.0 to −16.0 ∘C when liquid water path increases from 1.0 to 14.0 g m−2. The SLWC radiative forcing is positive and logarithmically increases from 0.0 to 70.0 W m−2 when liquid water path increases from 1.2 to 3.5 g m−2. This is mainly due to the downward longwave component that logarithmically increases from 0 to 90 W m−2 when liquid water path increases from 1.0 to 3.5 g m−2. The attenuation of shortwave incoming irradiance (that can reach more than 100 W m−2) is almost compensated for by the upward shortwave irradiance because of high values of surface albedo. Based on our study, we can extrapolate that, over the Antarctic continent, SLWCs have a maximum radiative forcing that is rather weak over the eastern Antarctic Plateau (0 to 7 W m−2) but 3 to 5 times larger over West Antarctica (0 to 40 W m−2), maximizing in summer and over the Antarctic Peninsula.
