GPS-INDEPENDENT AUTONOMOUS VEHICLE CONVOYING WITH UWB RANGING AND VEHICLE MODELS
Authors: Thompson Kyle , Jones Ben , Martin Scott , Bevly David
Published: November 2024

ABSTRACT

Leader-follower autonomous vehicle systems have a vast range of applications
which can increase efficiency, reliability, and safety by only requiring one
manned-vehicle to lead a fleet of unmanned followers. The proper estimation and
duplication of a manned-vehicle’s path is a critical component of the
ongoing development of convoying systems. Auburn University’s GAVLAB has
developed a UWB-ranging based leader-follower GNC system which does not require
an external GPS reference or communication between the vehicles in the convoy.
Experimental results have shown path-duplication accuracy between 1-5 meters for
following distances of 10 to 50 meters.

CREATION OF A GROUND SLOPE MAPPING METHODOLOGY WITHIN THE ROBOTIC TECHNOLOGY KERNEL FOR IMPROVED NAVIGATION PERFORMANCE
Authors: Ramsey Jackson , Brothers Robert , Hernandez Joseph
Published: November 2024

ABSTRACT

This paper presents a new terrain traversability mapping method integrated into
the Robotic Technology Kernel (RTK) that produces ground slope traversability
cost information from LiDAR height maps. These ground slope maps are robust to a
variety of off-road scenarios including areas of sparse or dense vegetation. A
few simple and computationally efficient heuristics are applied to the ground
slope maps to produce cost data that can be directly consumed by existing path
planners in RTK, improving the navigation performance in the presence of steep
terrain.

Tool Development for Mobility Visualization and Routing Incorporating
Vehicle Limitations and Terrain Modeling
Authors: Pesheck Eric , Goff Robert , Little Joseph , Jayakumar Paramsothy
Published: November 2024

ABSTRACT

In this investigation, a prototype tool for visualizing vehicle mobility and
planning routes across offroad terrain was developed and evaluated in the field.
The tool uses detailed vehicle, soil, and terrain characteristics to plan routes
and indicate vehicle limits, including go/no-go zones on the local terrain map.
Consistent with NG-NRMM principles, the process uses Multi-Body system
simulation and simple terramechanics soil models to characterize the vehicle
capability and integrate this data within a geospatial application to visualize
mobility over terrain and facilitate route planning. A tablet-based prototype
was soldier-tested in the field to confirm operational utility and selected
routes. The results indicate how the NG-NRMM approach and associated modeling
strategies can positively impact operational planning and execution.

EXPLORATION OF OIL FLOW AND HEAT TRANSFER PHENOMENON FOR GALLERY-COOLED DIESEL ENGINE PISTONS
Authors: Grunin Arkady , Korivi Vamshi
Published: November 2024

ABSTRACT

This paper details the exploration of oil jet piston cooling phenomenon with a
focus on heat transfer from the diesel engine piston to the oil. Several
numerical methods based on computational fluid dynamics (CFD) and conjugate heat
transfer (CHT) were developed to resolve key aspects of piston oil cooling.
These methods aim to establish and characterize the flow and heat transfer
regimes that are inherent to the piston gallery cooling system, and to assist in
quantifying the piston heat transfer and establish its dependence on a number of
parameters related to the engine layout and performance, the oil cooling system,
and the cooling gallery contained within the piston. Telemetry experimental data
from a single-cylinder diesel engine was used to better understand the piston
cooling system and to develop and validate modeling and simulation approaches.
The combined findings offer a foundation for further study of oil jet piston
cooling.

EXPLORING THE IMPACT OF DATA UNCERTAINTIES IN AUTONOMOUS GROUND
VEHICLE PLATOONING
Authors: Louis August St. , Calhoun Jon C.
Published: November 2024

ABSTRACT

To improve robustness of autonomous vehicles, deployments have evolved from a
single intelligent system to a combination of several within a platoon.
Platooning vehicles move together as a unit, communicating with each other to
navigate the changing environment safely. While the technology is robust, there
is a large dependence on data collection and communication. Issues with sensors
or communication systems can cause significant problems for the system. There
are several uncertainties that impact a system’s fidelity. Small errors
in data accuracy can lead to system failure under certain circumstances. We
define stale data as a perturbation within a system that causes it to
repetitively rely on old data from external data sources (e.g. other cars in the
platoon). This paper conducts a fault injection campaign to analyze the impact
of stale data in a platooning model, where stale data occurs in the
car’s communication and/or perception system. The fault injection
campaign accounts for different occurrences of a communication error. Our
analysis provides an understanding of the sensitivity of each model parameter in
causing system failures (e.g. a crash between vehicles within the platooning
model). By understanding which parameters are most influential to the fidelity
of the model, we enable the ability to make platooning algorithms safer.

Published: November 2024

ABSTRACT

Automotive electrical/electronic (E/E) architectures are continuously evolving to
meet the technological challenges of the highly connected, software-defined
vehicle. Advances are being made in µController/µProcessor
compute hardware, software, and cyber security methodologies, to provide
enhanced security, safety, flexibility and functionality.

These advancements will mature through millions of miles of road/lab testing and
reach TRLs suitable for use by the Army to implement safe and secure
cyber-resilient platforms for manned and unmanned ground vehicle systems.

This paper will describe three specific advances that will benefit Army vehicle
programs of the future: Software that leverages the Modular Open Systems
Approach (MOSA) as a secure and flexible Service Oriented Architecture (SOA)
framework; Hardware-based Communication Engines for high bandwidth/low latency
network communications; and a Hardware Security Module (HSM) that enhances the
cyber-resilience of the next generation of the Army’s neXtECU
module.

LEVERAGING ARTIFICIAL INTELLIGENCE (AI) TO ENABLE DECISION
SUPERIORITY
Authors: Taylor David , Kheyfets Emil , Stewart Timothy
Published: November 2024

ABSTRACT

Recent operations in Ukraine have proven that introducing new technologies,
tactics, techniques, and procedures can significantly affect the 21st
century battlefield. The U.S. military is integrating the lessons learned from
this and other recent conflicts into the Joint All Domain Command and Control
(JADC2) warfighting concept. DoD is seeking to achieve decision superiority
through JADC2 “to produce the warfighting capability to sense, make
sense, and act at all levels and phases of war, across all domains, and with
partners, to deliver information advantage at the speed of relevance." While
this definition captures what JADC2 aims to achieve, it says little about how to
achieve it. This paper uses the OODA loop and a project convergence use case
(wet gap crossing) to show how artificial intelligence (AI) will enable decision
superiority by reducing risk in this complex and relevant scenario.

ITERATIVE CO-DESIGN OF ORGANISATIONAL PROCESSES AND TOOLCHAINS FOR
MODEL-BASED RELIABILITY, AVAILABILITY MAINTAINABILITY & SAFETY
INTEGRATION
Authors: Langton Jake , Hilton Sam
Published: November 2024

ABSTRACT

A toolchain must be functionally cohesive with a business process, especially in
technical domains such as complex systems engineering. Despite the industry-wide
shift towards model-based digitization within engineering organizations, there
is a lack of development in implementing model-based RAMS (Reliability,
Availability, Maintenance, Safety) processes. This results in a missed
opportunity to create value throughout the entire system lifecycle, from
conceptual design to operations. This paper proposes some reasons for this and
outlines a framework for evaluating model-based toolchains in the context of the
entire Engineering cycle. A model-based architecture for RAMS is proposed and
contrastively evaluated with respect to SysML. Key use cases are identified, and
benefits are demonstrated using Maintenance Aware Design Environment
Software.

Microstructure analysis of TIG welded additively manufactured
prepared joints of Ni-based superalloys produced by Laser Powder Bed
Fusion
Authors: Geisen Ole , Steinberg Tad
Published: November 2024

ABSTRACT

Laser powder bed fusion (L-PBF) of entire assemblies is not typically practical
for technical and economic reasons. The build size limitations and high
production costs of L-PBF make it competitive for smaller, highly complex
components, while the less complex elements of an assembly are manufactured
conventionally. This leads to scenarios that use L-PBF only where it’s
beneficial and requires integration and joining to form the final product. Today
the welding process requires complex welding fixtures and tack welds to ensure
correct alignment and positioning of parts for repeatable results. In this
paper, both L-PBF and milled weld preparations are presented to simplify
Tungsten inert gas (TIG) welding of rotationally symmetrical geometries using
integrated features for alignment and fixation. All welds produced in this study
passed the highest evaluation group B according to DIN 5817.

Scan Sequence Optimization for Reduced Residual Stress and Distortion in LPBF Additive Manufacturing – An AISI 316L Case Study
Authors: He Chuan , Okwudire Chinedum E.
Published: November 2024

ABSTRACT

Laser powder bed fusion (LPBF) additive manufacturing often results in defective
parts due to non-uniform temperature distribution during fabrication. To
mitigate this issue, the authors recently introduced SmartScan, an intelligent
method that employs modeling and optimization to generate scan sequences that
improve temperature uniformity. However, the previous version of SmartScan could
only be applied to single layers. This paper presents an extension of SmartScan
to three-dimensional parts by adjusting the thermal model and optimization
objective. Through simulations and experiments involving fabricating AISI 316L
stainless steel parts, the study demonstrates that the proposed SmartScan
approach significantly improves temperature uniformity, reduces part distortion,
and mitigates residual stress, as compared to conventional heuristic
sequences.

Authors: Rufner Jorgen , Leonard Clifford , Nutt Steven , Nguyen Kevin
Published: November 2024

ABSTRACT

High performance fiber reinforced ceramic rotors have the potential to greatly
improve metrics in heavy vehicles such as braking distance, acceleration time,
maximum speed, fuel consumption, improved handling, and increased vehicle
maximum loads. Three types of carbon ceramic composite brake rotor materials
were created using polymer infiltration pyrolysis (PIP) for carbon fiber
reinforced silicon oxicarbide, reactive melt infiltration (RMI) for carbon fiber
reinforced silicon carbide, and electric field assisted sintering (EFAS) for
carbon fiber reinforced silicon carbide-zirconium diboride to investigate the
manufacturing of 396mm diameter heavy vehicle brake rotors. The microstructure
of parts created by each manufacturing method were discussed and contrasted. The
EFAS manufactured rotor created the highest quality part due to extremely fast
processing times, uniform material microstructure, and fusing of adjacent fibers
in the carbon fiber network. Thermal conductivity was measured to be greater
than that of a traditional steel rotor.

A LOW POWER AND HIGH PERFORMANCE SOFTWARE APPROACH TO ARTIFICIAL INTELLIGENCE ON-BOARD
Authors: Ghiglino Pablo , Harshe Mandar
Published: November 2024

ABSTRACT

New generations of ground vehicles are required to perform tasks with an
increased level of autonomy. Autonomous navigation and Artificial Intelligence
on the edge are growing fields that require more sensors and more computational
power to perform these missions. Furthermore, new sensors in the market produce
better quality data at higher rates while new processors can increase
substantially the computational power. Therefore, near-future ground vehicles
will be equipped with large number of sensors that will produce data at rates
that has not been seen before, while at the same time, data processing power
will be significantly increased. This new scenario of advanced ground vehicles
applications and increase in data amount and processing power, has brought new
challenges with it: low determinism, excessive power needs, data losses and
large response latency. In this article, a novel approach to on-board artificial
intelligence (AI) is presented that is based on state-of-the-art academic
research of the well known technique of data pipeline. Algorithm pipelining has
seen a resurgence in the high performance computing work due its low power use
and high throughput capabilities. The approach presented here provides a very
sophisticated threading model combination of pipeline and parallelization
techniques applied to deep neural networks (DNN), making these type of AI
applications much more efficient and reliable. This new approach has been
validated with several DNN models and different computer architectures. The
results show that the data processing rate and power saving of the applications
increase substantially with respect to standard AI solutions, enabling real AI
on harsh environments like ground vehicle deployment.

Transient Torque Response of Tracked Vehicle Suspension Rotary Dampers
Authors: Ostberg David , Redner Kenneth , Allen Samuel
Published: November 2024

ABSTRACT

Damper models used in Multi Body Dynamics simulations of tracked vehicles are
commonly defined solely by damper curves, that is stabilized damper reaction
torque as a function of steady state velocity. In reality, the achievement of
the stable reaction torque lags behind damper curve torque upon attainment of a
given velocity. As detailed in this paper, the idealization to reduce damper
performance to a “damper curve” cannot produce an accurate
representation of the two primary terrains military vehicles are designed
against: half-round and ride quality courses. By introducing
“compliance” and “lash”, the damper performance
can be accurately represented. With the slight extension of this model to a
fully physics based one, future dampers can be designed to expand the operating
performance envelope of tracked vehicles.

Authors: Mafimisebi Peter
Published: November 2024

This study examined the sedimentological and petrographic characteristics of the Ogun River bridge sediments around the Dahomey Basin, Southwestern Nigeria. A cumulative frequency curve was obtained by plotting grain size (Phi (ᴓ)) versus cumulative percentage. The phi values at 5%, 16%, 25%, 50%, 75%, 84%, and 95% percentages were read from the plotted o-give curve. Gravimetric analysis was conducted on five samples collected from Ogun River to determine sediment sedimentology and depositional environment. Grain-size analysis results indicate that Ogun River sediment is poorly to very poorly sorted, and coarse to very coarse-grained in texture indicating less winnowing and abrasion. Six (6) specimens are analyzed under thin sections. The result shows the heavy minerals composition of the River Ogun sediments have high proportion of Zircon and Staurolite compared to Rutile in the sediment. In conclusion, the sequence of the sediments comprises fluvial to marine-dominated sediments which are proximal to distal from the source, sourced from both igneous and metamorphic origin, mineralogical mature, texturally immature to mature, and are formed under warm and humid conditions.

study sought to establish the prevalence, morphological classifications, and factors associated with severe anemia among children attending Itojo Hospital. A hospital-based cross-sectional study design was used in this study in which children aged less than 5 years who attended the pediatric ward at Itojo Hospital were involved. Patients were consecutively recruited until a sample size of 296 was obtained. Data were collected from patients’ caregivers with a structured questionnaire. Data analysis was done using SPSS Version 20.0. Descriptive statistics and bivariate and multivariate logistic regression were used during data analysis. Multiple logistic regression models were used to show the strength of the relationship and the likelihood that each of the factors would lead to severe anemia among children under 5 years. Of the 296 patients enrolled, the prevalence of severe anemia was 13.9%. The Majority of the patients (50.7%) had microcytic anemia, followed by 32.8% with normocytic anemia. Factors that were significantly associated with severe anemia were the age of the child (P=0.029), HIV/AIDS (P=0.000), leukemia (P=0.000), and sickle cell disease (P=0.000). The prevalence of severe anemia among children less than five years of age was found to be relatively high hence increasingly becoming a public health problem. There is a need for age-specific interventions that comprehensively address the issue of improved nutrition, prevention, and management of HIV infection as well as chronic and genetic disorders.

Anencephaly is an inborn deformity of the central nervous system that results to the failure of closure of the cranial end of the embryologic neural tube, typically happens between the 23rd to 26th days after conception. It represents 40% of neural tube deformities, which is the second foremost cause of nervous system abnormalities after spina bifida. The occurrence rate is 1/1,000. Diagnosis is made by the 1st trimester ultrasound between the 11th and 14th week. Etiologies are multifactorial (toxic, metabolic, nutritional, iatrogenic and exceptionally chromosomal). The importance of this case report is to highlight the role of imaging in the making prenatal diagnosis and thereby reiterating the usefulness of anomaly scan in pregnant women in our clime. Ultrasound is a non-ionizing imaging modality which is highly operator dependent and is repeatable. Our case study is a 36-years-old woman Gravida 3 Para 1+2 (None Alive) at 24weeks 1day Gestation age (GA) who presented to the Radiology department for routine obstetric scan for the first time in index pregnancy. The obstetric ultrasound shows absence of the cranium in an active fetus with good cardiac activity (fetal heart rate =158bpm) with increase amniotic fluid in transverse lie. Frog eye sign was also appreciated. The placenta is sited anteriorly and not low lying. Femoral length (FL) measures 4.31cm with a GA of 24 weeks 1 day.

Testicular microlithiasis is a rare finding in intratesticular pathology, and its association with Leydig cell hyperplasia is not widely reported. We present a case of such an association. 19-year-old male presented with bilateral testicular microlithiasis on ultrasound, and elevated tumor markers. Inguinal orchiectomy revealed Leydig cell hyperplasia. Discussion: Testicular microlithiasis is increasingly detected due to advancements in ultrasound technology, but its clinical significance remains unclear. Leydig cell hyperplasia, characterized by testicular nodules, is rarely associated with microlithiasis. This case underscores the need for vigilance in evaluating testicular abnormalities, as severe microlithiasis and Leydig cell hyperplasia may mimic malignant lesions.

Published: November 2024

This study seeks to ascertain not just the economic repercussions of industrialization on the Mimika tribe in Papua Province, but also how these transformations are altering social and institutional dynamics, notably in terms of traditional leadership. This research was conducted from January 2024 to March 2024 focusing on the Comorian District, especially the Komoro Mimiko Tribe, Papua Province. The data collection techniques used in this study are in-depth interviews with members of the Comoro District, particularly the Comojima tribe, indigenous leaders, industrial workers, and other stakeholders, participatory observation, and holding FGDs with Komoria community groups. The results show that there has been a change in cultural values and traditions stemming from engagement with modern elements. Non-Governmental Organizations (NGOs) prioritizing cultural and ecological diversity advocate for the rights of indigenous communities. Conversely, governmental entities adopt a pragmatic stance, viewing modernization as integral to economic advancement. However, they also acknowledge the significance of preserving cultural sustainability and indigenous rights. To this end, they formulate policies facilitating the harmonization of modernities with traditional practices. The interaction between tradition and modernity sees complexity as well as divergence of views among various stakeholders. In general, these results underscore the difficulties and possibilities associated with striking a balance between modernization and indigenous traditions.

Authors: Allyarista Dhea Firnanda Airin , Asmaningrum Nurfika , Ardiana Anisah , Darmawan I Kade Iman
Published: November 2024

Urinary Tract Infections (UTIs) are a prevalent form of Healthcare-Associated Infections (HAIs) in patients with chronic kidney disease (CKD), especially those undergoing urinary catheterization. It is estimated that UTIs affect up to 25% of catheterized patients, significantly impacting morbidity and healthcare costs (World Health Organization, 2021). This study aims to determine how health education regarding urogenital hygiene can increase knowledge and prevent infection for patients undergoing urinary catheterization. This research is quantitative descriptive using a case study approach. A one-group pre-test post-test design was employed to collect data through the administration of pre-test and post-test knowledge assessments before and after health education. The results demonstrated a significant increase in knowledge scores from 67 to 93, indicating the effectiveness of health education in enhancing knowledge about urogenital hygiene. Furthermore, observation of signs and symptoms of UTIs showed a decrease in symptoms during the patient's treatment, highlighting the positive impact of health education.

Authors: Roque Desiderio da Silva João Guilherme , Sanches Wagner Francisco
Published: November 2024

A pejotização, prática de contratação de trabalhadores como pessoas jurídicas (PJs) ao invés de empregados formais, tem sido utilizada como estratégia para reduzir custos trabalhistas, mas frequentemente desvirtua os direitos garantidos pela Consolidação das Leis do Trabalho (CLT). Este trabalho analisa os impactos dessa prática na proteção aos direitos dos trabalhadores, considerando os princípios fundamentais do Direito do Trabalho, como a pessoalidade e a subordinação. Com base no princípio da primazia da realidade, discute-se como a pejotização mascara relações de emprego legítimas, resultando na exclusão de direitos como férias, 13º salário e contribuições previdenciárias. Também são avaliadas as consequências sociais e econômicas dessa prática, como a precarização do trabalho e a evasão de encargos tributários. Por meio de análise teórica e jurisprudencial, evidencia-se a necessidade de fortalecer mecanismos legais e institucionais para coibir fraudes trabalhistas e assegurar a dignidade do trabalhador.

Authors: Antunes Gabriela Cristina , Pimenta Meneguce Cassia
Published: November 2024

O presente artigo analisa a limitação à liberdade de testar no ordenamento jurídico brasileiro, com ênfase na necessidade de respeito à legítima. No Brasil, o direito de testar, embora garantido, é restringido pela obrigação de reservar 50% do patrimônio do de cujus aos herdeiros necessários (descendentes, ascendentes e cônjuge), conforme disposto nos artigos. 1.845 e 1.846 do Código Civil. A legítima visa proteger a família e garantir uma divisão equitativa do patrimônio. A violação dessa norma resulta em consequências jurídicas como a redução das disposições testamentárias e, em alguns casos, a nulidade parcial do testamento, conforme os artigos. 1.967 e 1.969. Além disso, doações em vida que excedem a parte disponível também estão sujeitas a revisão judicial, conforme os artigos. 2.002 e 2.007 do Código Civil. Autores como Maria Helena Diniz, Silvio de Salvo Venosa e Zeno Veloso destacam a importância da legítima como mecanismo de proteção dos herdeiros necessários, ressaltando seu caráter de norma de ordem pública. A jurisprudência brasileira confirma a centralidade da legítima na sucessão, consolidando sua função de limitar a liberdade de testar e assegurar uma herança justa e equânime. O artigo conclui que a legítima é essencial para garantir a função social da herança no direito sucessório brasileiro.
Understanding Economic Growth in India: How It Affects the Everyday Lives of Common People
Authors: Sinha Jitendra Kumar
Published: November 2024

India has witnessed significant economic progress over the past two decades, positioning itself for sustained growth over the next 30 years. However, the key challenge remains in transforming this potential into actual economic gains. This study aims to identify the primary drivers of India's economic growth by analyzing key indicators—consumption, fixed asset investment, exports, gross domestic product (GDP), and employment—between 2000 and 2023. Using multiple regression analysis conducted with E-Views software, the results demonstrate that consumption, fixed asset investment, exports, and employment have positive and statistically significant impacts on GDP growth. The findings reveal that fixed asset investment plays a pivotal role in enhancing capital stock, while consumption drives domestic demand, contributing to GDP expansion. Exports further bolster growth through international trade, while employment improvements lead to better resource utilization.
Based on these insights, the study proposes critical policy recommendations: (i) enhancing social security systems and expanding access to credit to stimulate consumer spending; (ii) prioritizing rural development and promoting innovative industries to ensure a balanced distribution of investment across regions; (iii) optimizing export structures by encouraging technological advancements in key sectors; and (iv) improving workforce quality by aligning education with market demands and offering targeted vocational training. These measures are essential for sustaining India’s economic momentum and ensuring long-term, inclusive growth. The study’s findings provide valuable direction for policymakers seeking to address existing bottlenecks and capitalize on India’s growth potential for sustainable development.
