Co-Optimization of a Fuel Cell Hybrid Heavy-Duty Vehicle Using a State Machine Control
Authors: Aliberti Paolo , Bove Giovanni , Sorrentino Marco
Published: September 2024

The global push towards reducing emissions in road transport has intensified, necessitating the adoption of more sustainable powertrain solutions. Fuel cells have emerged as a prominent alternative to solve the limitations associated with battery-powered vehicles, such as range anxiety and excessive weight. Specifically, this study focuses on heavy-duty vehicles sector and seeks to simultaneously accomplish vehicle design and proper energy management of a hybrid truck utilizing both fuel cells and batteries. Therefore, a model-based approach is used to develop a techno-economically viable co-design procedure, which iteratively changes the design parameters (i.e., fuel cell system rated power and battery specific energy), to allow maximizing vehicle fuel economy over a designated driving mission. Such a task is successfully executed through the implementation of a versatile rule-based control strategy suitably tailored to meet the specific requirements of heavy-duty vehicles. Moreover, the fuel cell system has been modeled as a finite state machine, with its operating behavior, depending on power request, managed via Boolean-like rules in Stateflow environment. Since a fuel cell-based truck is a suitable choice, especially when there is no time for rapid battery charging, the proposed co-optimization faces several scenarios, distinguished by the allowable post-driving battery charging time. This holistic approach aims to fine-tune the vehicle's energy use, ensuring optimal performance and meeting predefined criteria, with a primary emphasis on increasing fuel economy. Considering the HHDDT driving cycle, results close to 11.10 km/kg are achieved in the various scenarios. Furthermore, the influence of the payload capacity on the optimal design was also investigated, along with the effects of different driving routes. The shift to the ETC-FIGE resulted in a 2% reduction in fuel economy, leading to fuel cell system and battery capacity downsized by approximately 18% and 20%, respectively, depending on the admitted post-driving recharging time.

Authors: Federici Leonardo , Lombardi Simone , Tribioli Laura , Bella Gino
Published: September 2024

Nowadays, the increase in the global population and the rise in living standards lead to a growing number of cars on the roads, resulting in an increase in emissions. It becomes crucial for society to make efforts to modernize the entire vehicle fleet to emission standards adequate for combating climate change, accelerating the natural turnover of older vehicles whenever possible. For this reason, the following study delves into the category of mild hybrid electric vehicles, which can be easily obtained through retrofitting practices from existing vehicles, thus enabling the enhancement of a large number of cars using minimal materials and requiring minimal time.

The present paper focuses on the performance of the traction electric machine, whose dynamic model - based on the equivalent circuit model of a surface synchronous permanent magnet electric motor - is shown to allow for an accurate representation of instantaneous power and efficiency during its operation. Still, this motor model is interfaced with the 1D fluid dynamics model of the thermal engine, which enables precise simulation of combustion processes and gas dynamics, and a first-order dynamic model of the lithium-ion battery to provide a more reliable estimation of its response to varying load conditions and state of charge.

Published: September 2024

Electrification or hybridization of commercial vehicles offers a promising avenue for mitigating emissions in urban environments. This concept is particularly applicable to waste collection vehicles, which move in urban contexts along repeatedly chosen driving cycles. Municipal waste collection and transport are functional tasks which have a significant impact on the urban environment in terms of energy consumption and CO2 emissions. In this work, the evaluation of a full-electric powertrain was carried out for a small size waste collection vehicle operating in the historic center of the city of Perugia (Italy). First, the vehicle model was developed and validated against literature data using a full-electric powertrain. The model allows to evaluate energy consumption and system efficiency considering the real driving path and the mass variation due to the waste collected during the route. Real driving data (position, slope, collection stops) were obtained through an experimental campaign carried out by the local waste management company (Gesenu SpA), and implemented directly in the model developed in a system-level simulation environment (GT-Power). Subsequently, three different scenarios were compared in terms of waste weight transported to predict energy consumption, environmental impact and vehicle ranges.
Optimal Eco-Driving with Infrastructure-to-Vehicle Communication for Speed Adaptation Based on Real-Time Dynamic Macroscopic Traffic Conditions
Authors: Villani Manfredi , Shiledar Ankur , Block Brian , Spano Matteo , Rizzoni Giorgio
Published: September 2024

Eco-driving algorithms use the available information about traffic and route conditions to optimize the vehicle speed and achieve enhanced energy consumption while fulfilling a travel time constraint. Depending on what information is available, when it becomes accessible, and the level of automation of the vehicle, different energy savings can be achieved. In their basic formulation, eco-driving algorithms only leverage static information to evaluate the optimal speed, such as posted speed limits and location of stop signs. More advanced algorithms may also consider dynamic information, such as the speed of the preceding vehicle and Signal Phase and Timing of traffic lights, thus achieving higher energy efficiency. The objective of the proposed work is to develop an eco-driving algorithm that can optimize energy consumption by leveraging not only static route information, but also dynamic macroscopic traffic conditions, which are assumed to be available in real-time through Infrastructure-to-Vehicle communication. In this work, modeling and simulation are used to demonstrate the operation of the algorithm, which is implemented in the controller of an electric truck model. The speed optimization is formulated as an optimal control problem and solved as a hierarchical Model Predictive Control using Approximate Dynamic Programming. Macroscopic traffic congestion is modelled as a dynamic process using the Lighthill-Whitham-Richards model, which is a first-order hyperbolic partial differential equation that models the spatial and temporal evolution of traffic density. The results show that for heavy traffic conditions, the speed adaptation based on real-time macroscopic traffic conditions, that is, considering the characteristic macro scales of traffic congestion, can result in reduced energy consumption, while not affecting the total travel time.
Quantitative Evaluation of AI Productivity and Quality in Design Processes: A Case Study on Engine Piston Diameter Calculation and 3D Modeling
Authors: Gutierrez Marcos , Taco Diana
Published: September 2024

Artificial Intelligence (AI) is currently regarded as the foremost technology for automating routine and repetitive tasks, leading to increased productivity. However, the quality of creative and design work with AI remains questionable. This paper presents a quantitative analysis of AI productivity through dynamic simulation and assesses the quality of AI results in the diameter calculation and construction of a 3D model of an engine piston as a case study. To evaluate productivity, the dynamic model segregates design tasks based on AI working hours. The quality of the formulation for calculating the engine piston diameter, derived from engine requirements, is compared with a standard formulation from a literature review. Additionally, the 3D model generated by AI is compared with a model created by human intelligence in Computer-Aided Design (CAD) software, reflecting the characteristics and properties of real engine pistons. While research on AI productivity is abundant, few studies address the quality and usefulness of AI-generated results. This study aims to evaluate these three aspects. As anticipated, the AI in a simulation model demonstrates a numerical increase in productivity as an enhancing variable. However, results for a design process involving mathematical formulation and 3D model construction lack utility without additional work. Our findings lead us to conclude that AI in the design process can enhance productivity when used to suggest and predict design instructions, thereby saving time. Nevertheless, the AI's ability to create mathematical and 3D models is limited to simplified conditions, and further knowledge must be imparted to the AI to enable it to produce readily usable designed components.
Study of Particle Emissions Due to Brake Wear: Impact of Braking Profiles and Transport Efficiency of the Test System
Authors: Catapano Francesco , Di Iorio Silvana , Magno Agnese , Vaglieco Bianca Maria
Published: September 2024

Vehicular emissions represent the main responsible of the deterioration of air quality in the urban area. In the attempt to reduce both gaseous emissions and particulates from internal combustion engines, increasingly stricter regulations were introduced from European Union in the last years. These limits have led to the improvement of emissions-reduction technologies as well as the vehicle hybridization and electrification. In this scenario, vehicle emissions due to other sources rather than the propulsion systems, such as brakes and tires, have taken a significant weight. In this regard, European Commission has proposed the introduction in the next EURO 7 standard of the first-ever limit on the particles emitted by vehicle brakes.

This study is devoted to improving the knowledge on the particle characteristics due to the brake wear by means of laboratory experiments thus providing support to the definition of the new standards. An experimental layout was realized consisting in a box where a brake for light duty applications was enclosed. Particles were measured in the size range from 5.6-560 nm and 0.3-10 μm through an EEPS and an OPS, respectively. A section of the standardized cycle for brake emissions and a properly realized profile characterized by intense braking were tested. The impact of the inlet air flow on the measure of the particles was also discussed.

The experimental results highlighted the role of braking profiles on the physical characteristics, number and size, of the particle emissions. Low concentration and large diameter particles were emitted under urban driving conditions. On the other hand, hard braking increased the number of particles especially in the small size range.
Neural-Network-Based Modeling of SCR Systems for Emission Simulation: A Comprehensive Approach
Authors: Sapio Francesco , Aglietti Filippo , Ferreri Paolo , Savuca Alexandru
Published: September 2024

Selective Catalytic Reduction (SCR) systems are crucial for automotive emissions control, as they are essential to comply with stringent emissions regulations. Model-based SCR controls are used to minimize NOx emissions in a broad range of real-word driving scenarios, constantly adapting the urea injection to diverse load and temperature operating conditions, also accounting for different catalyst ageing status. In this framework, Neural Networks (NN) based models offer a promising alternative to reduced-order physical models or map-based controls.

This study introduces a hybrid modeling approach for SCR systems, leveraging the integration of machine learning techniques with detailed physics-based models. A high fidelity 1D-CFD plant model of a SCR catalyst, previously calibrated on experimental data, was used as digital twin of the real component. A standardized simulation protocol was defined to virtually characterize the SCR thermal and chemical behavior under the full range of operating conditions typically covered during the real operation of the system. The generated dataset, including hard-to-measure physical quantities such as the catalyst wall temperature and the ammonia storage, was used to train and validate the neural network models. In particular, Recurrent Neural Networks (RNN) were used to mimic catalyst wall temperature and ammonia storage temporal trends, while Feed Forward Neural Networks (FFNN) were applied to model SCR outlet temperature and species concentrations such as NOx and NH3.

The NN-based SCR model predictive capabilities were assessed against experimental driving cycles data. The results show that the NN model is able to accurately capture the non-linear characteristics of the system behavior, even under the highly transient conditions typical of real-driving scenarios, thus confirming the reliability of the proposed methodology.

Validation and Verification of Integrated Vehicle Health Management Systems
Authors:   HM-1 Integrated Vehicle Health Management Committee
Published: September 2024

This SAE Aerospace Recommended Practice (ARP) provides guidance to plan and perform validation and verification of IVHM systems. The intent of this ARP is to help the reader appreciate and understand additional objectives and activities of validation and verification processes, beyond validation and verification of the vehicle, that arise due to the nature of an IVHM System. This includes an end-to-end evaluation of the entire IVHM system, noting that IVHM is a “system of systems.” In order to perform validation and verification, the user must determine what they are using IVHM for, including the criticality of the application. The process should then determine appropriateness of the data corresponding to the application criticality.

This document provides validation and verification guidance for IVHM as: (1) a system of systems, (2) a system, and (3) elements within a system. While this document is not intended to be prescriptive, it is a reference guide that highlights and discusses some attributes of IVHM and its uses that typically necessitate special handling during validation and verification.

For more information about validation and verification processes required for onboard aerospace applications, please refer to ARP4754 (for development process), ARP4761 (for safety assessment process), RTCA DO-178 (for software), RTCA DO-254 (for hardware), and FAA guidance provided by AC 25.1309-1A. The validation and verification processes identified in the standards cited above must be considered where IVHM elements are part of an airborne system. See 1.3 for a more detailed overview.

Test Method for Measuring Performance of Engine Cooling Fans
Authors:   Cooling Systems Standards Committee
Published: September 2024

This SAE Recommended Practice is intended for use in testing and evaluating the approximate performance of engine-driven cooling fans. This performance would include flow, pressure, and power. This flow and pressure information is used to estimate the engine cooling performance. This power consumption is used to estimate net engine power per SAE J1349. The procedure also provides a general description of equipment necessary to measure the approximate fan performance.

The test conditions in the procedure generally will not match those of the installation for which cooling and fuel consumption information is desired. The performance of a given fan depends on the geometric details of the installation, including the shroud and its clearance. These details should be duplicated in the test setup if accurate performance measurement is expected. The performance at a given air density and speed also depends on the volumetric flow rate, or the pressure rise across the fan, since these two parameters are mutually dependent. These parameters depend on the pressure drop across the radiator core and the ram pressure due to vehicle motion. For these reasons, the test procedure should be recognized as providing only an approximate measure of installed fan performance.

Although the test procedure is based on running the fan with a motoring dynamometer, the actual installation can be used as a test fixture if an accurate torque meter is available. In this case, the same qualifications discussed apply.

For the effect of a fan clutch in reducing fan use and power consumption, which is not a part of this procedure, refer to SAE J1342.

Performance testing of electric cooling fan assemblies is covered in SAE J2867.

Remediating diesel-contaminated soil with a biodegradble surfactant as Triton alternative: Nonylcyclohexanol ethoxylate
Authors: Hu Xueyi , Liu Jianyi , Zhang Yongjin , Zhang Guiju , Xia Yongmei
Published: September 2024

The newly forbidden surfactant nonylphenol polyethoxylates (NPEOn, similar as Triton) was considered as a promising eluent for remediating diesel-contaminated soil but remaining a secondary pollution due to their aquatic toxicity. Herein, a comprehensive study is conducted about the performance of a group of new surfactants nonylcyclohexanol ethoxylates (NPEOn</sub) on remediating diesel-contaminated soil, with comparison of NPEO10, along with the nonionic-anionic combination of NCEO9-sodium dodecylbenzene sulfonate (NCEO9-SDBS). With 1 wt% of NPEOn</sub solution, the elution efficiency on diesel in soil reached up to 86.8% at 25°C in 24 h, which was comparable to that of NPEO10. The mechanism of reducing polyethoxylate surfactant adsorption on soil surface by anionic surfactant was profiled with energy dispersive X-ray spectroscopy, thermogravimetric analysis and zeta-potential analysis. The kinetics of diesel desorption from contaminated soil enhanced with surfactants is found to follow the Elovich equation. Moreover, the bean germination and growth experiment further prove that the NCEO9 washing improved the cultivability of diesel-contaminated soils, especially inspiring the red bean growth that did not germinate in the contaminated soil at all. The findings will be benefit for developing environmentally friendly surfactant systems to clean-up diesel-contaminated soils, and for replacing NPEO10 with NCEO9 in soil remediation applications.

Authors: Chicombo Tomé Francisco , Moreira Alecir Antônio Maciel
Published: September 2024

Este artigo traz uma reflexão sobre a vulnerabilidade às inundações, seus diversos componentes, abordagens metodológicas, escalas de análise e principais medidas para a construção da resiliência. O estudo baseou-se em revisão teórico-conceitual como método para a sua elaboração. Constatou-se que quatro principais abordagens são usadas quando se trata de avaliação da vulnerabilidade às inundações, a saber: as curvas de vulnerabilidade, matrizes de danos,  indicadores de vulnerabilidade e  abordagens baseadas na modelagem. Essas abordagens adotam escalas de análise que variam da realidade micro à nacional, passando pela local e regional. A construção de medidas que conduzem à resiliência deve atender a vários domínios, onde se destacam o físico-ambiental, o social, o econômico, o socio-comportamental e o politico-administrativo, todos abordados de forma integrada. A principal conclusão deste estudo é que as abordagens de avaliação às inundações devem sempre ter como base de análise: o contexto no qual elas ocorrem e a vulnerabilidade como caraterística intrínseca de um sistema ou elemento. Por outro lado, a adoção das estratégias de adaptação deve ser realizada de forma holística e integrada, atentando-se para a forma com que cada fator contribui particularmente para acentuação da vulnerabilidade em comunidades.

The Wnt signaling pathway plays a critical role in various biochemical processes, including embryonic development, tissue homeostasis, and cancer progression. In this paper, we conduct a comparative analysis of $\beta$-catenin-dependent Wnt signaling reaction networks, which we refer to as Feinberg, Schmitz, and MacLean models, based on the previous study by MacLean et al. (PNAS USA 2015). Using the methods of finest independent decomposition (FID) and Equilibria Parametrizations (EP), along with our newly developed Common Reactions Equilibria (CORE) and Concordance Profile (CP) analyses, we uncover three interesting results. Firstly, employing FID and EP reveals that both the Schmitz and MacLean models lack absolute concentration robustness (ACR) property, whereas the Feinberg model demonstrates ACR in a single species. Second, utilizing FID and CORE unveils significant relationships within the equilibria sets of augmented Schmitz and MacLean models, while also highlighting the lack of substantial associations between Feinberg and MacLean models. Finally, based on concordance levels, CP analysis indicates greater similarity between MacLean and Schmitz models compared to MacLean and Feinberg models. Therefore, the methods could detect differences between models that are not evident in the standard reaction network analysis.

We investigate a discrete counterpart of planar dynamical system of nonlinear differential equations induced by kinetic differential equations for a two-species chemical reaction. Chemical reactions exhibit a wide range of dynamical behavior. We show how the theoretical analysis provides insight into the potential behavior of chemical reaction systems, determining the areas of parametric space which indicate scenarios for local stability, then for one type of bifurcation co-dimension one and one type of bifurcation co-dimension two. Precisely, we prove the existence of period-doubling bifurcation and 1:2 resonance bifurcation also, by using the center manifold theorem and the technique of normal forms. All mathematical investigations are illustrated with numerical examples, bifurcation diagrams, Lyapunov exponents and phase portraits.
Oro-facial Cleft in Nasomaxillo-acrodysostosis (Binder): Orthopaeddontics and Surgery
Authors: Prinsloo Rolanda
Published: September 2024

Nasomaxillo-acrodysostosis or Binder’s syndrome in a patient with a cleft lip and palate anomaly is infrequent. This case report underscores a unique surgical outcome achieved through an integrated orthopaeddontic and maxillofacial surgical approach within a multidisciplinary team. The treatment, initiated during a significant paediatric growth phase, was remarkably successful during the orthopaeddontic phase. The result obtained due to the successful early orthopaeddontic intervention significantly altered the initial plan for major midfacial orthognathic surgical reconstruction. As a result, the child born with this twin facial anomaly experiences a more typical development trajectory with fewer disruptions from extensive oro-facial reconstructions.

The case underscores the importance of early maxillary expansion across multiple dimensions during the critical paediatric growth period. This approach was pivotal in achieving a positive outcome, ultimately reducing the need for major invasive surgical procedures. The success of the treatment was also attributed to the dedicated collaboration among the healthcare professionals, the patient’s commitment and the family’s strong support.

Published: September 2024

AES is yet one of the prominent cryptographic algorithms of the 21st century with the reputation of excellent performance and reliability. AES revolves around the S-Box, a nonlinear substitutive table that is essential to attain the level of cryptosecurity. In this paper, there are several methods discussed as how to increase AES S-Box functionality with regard to new cryptographic threats and their effectiveness. We detail the consequences of raising S-Box length and size, dynamical S-Box producing, higher nonlinearity, and efficient methods of SBox calculation by means of hardware and software. Furthermore, it explains the issues with these improvements and how they impact security measures & relevant computations. Here it is possible to state that applying all these modern approaches, it is possible to strengthen the AES S-Box essentially and ensure compliance with present day demands to cryptographic solutions.

Jesus was a great teacher who set an example of humility, especially in teaching love to His students in various ways or methods. Love is very easy to say, it is easy to explain good theories about love, but in reality, good theories are not balanced with good life practices. The research method that the author uses is a qualitative approach with a descriptive method, explaining it in a hermeneutic way, namely a method that expresses, translates, and interprets. The source material is the biblical text to gain an understanding of the biblical text. The research aims to discover the principles of love contained in Romans 13: 8-14, to provide a deep understanding of this text so that believers can implement love correctly. The result of his research is Jesus as the Foundation of Love. Jesus Christ is the armor of light, wearing the Lord Jesus. The correct attitude of love is don’t owe anything, love each other, love your neighbor as yourself, don't commit adultery, don't kill, don't steal, don't covet and any other word, love doesn't do evil to fellow human beings because love is the fulfillment of the law. The action is to continue living in Love because time is getting shorter by having to wake up from sleep, put off the deeds of darkness put on the armor of light, and live according to God's will. Yesus adalah guru agung yang memberikan teladan kerendahan hati terkhusus dalam mengajarkan tentang kasih kepada murid-murid-Nya dengan berbagai cara atau metode. Kasih sangat mudah untuk diucapkan, mudah untuk menjelaskan teori-teori yang baik mengenai kasih, tetapi pada kenyataanya teori yang baik itu tidak diimbangi dengan praktek hidup yang baik pula. Metode penelitian yang penulis gunakan adalah pendekatan kualitatif dengan metode deskriptif, menguraikannya dengan cara hermeneutik yaitu sebuah metode yang mengekpresikan, menterjemahkan dan menafsirkan. Sumber bahannya adalah teks Alkitab dengan tujuan untuk memperoleh pemahaman dari teks alkitab. Tujuan penelitian adalah untuk menemukan prinsip-prinsip kasih yang terdapat dalam Roma 13: 8-14, supaya memberikan pemahaman yang mendalam mengenai teks ini sehingga orang percaya dapat mengimplementasikan kasih secara benar. Hasil penelitiannya adalah Yesus sebagai Dasar Kasih. Yesus Kristus sebagai perlengkapan senjata terang, mengenakan Tuhan Yesus. Sikap Kasih yang benar yaitu jangan berhutang apa-apa, saling mengasihi, mengasihi sesama seperti diri sendiri, jangan berzinah, jangan membunuh, jangan mencuri, jangan mengingini dan firman lain manapun juga, kasih tidak berbuat jahat terhadap sesama manusia karena kasih adalah kegenapan hukum taurat. Tindakan untuk terus hidup dalam Kasih karena waktu yang semakin singkat dengan harus bangun dari tidur, menanggalkan perbuatan-perbuatan kegelapan dan mengenakan perlengkapan senjata terang dan hidup sesuai kehendak Tuhan.
