Oil refineries and petrochemical facilities contribute to the pollution of the environment either air, water, or soil releasing hazardous and toxic air pollutants into the atmosphere. These include nitrogen oxides (NOx), carbon monoxide (CO), hydrogen sulfide (H2S), sulfur dioxide (SO2), and particulate matter (PM), affecting both environment and human health. In the range of air pollutants, hydrogen sulfide is less monitored and reported despite its importance in determining adverse effects. Background H2S concentrations in air were found to range commonly from 0.11 ppb to 0.33 ppb. The concentrations in urban areas can reach 1 ppb (~1.4 g m-3) up to more than 90 ppb (~125 g m-3) near sources of H2S emissions. In Romania, the standard for the air in protected areas for the hydrogen sulfide pollutant provides an admissible concentration, over a maximum interval of 30 minutes, of 15 µg/m³. Everything that exceeds this value is considered harmful to human health. The statistics for the H2S time series recorded in Ploiești City by the mobile laboratory of the Environmental Protection Agency Prahova between 2019 and 2021 with a sampling rate of 30 minutes showed that the mean ranged between 1.51 and 3.74 µg/m³, while the maximum reached 59.36 µg/m³ in the east of Ploiești in 2019. Overall, the highest variance occurred in the East and North parts due to the presence of the concentration peaks. Hydrogen sulfide must be considered on the public health agenda, both from the occupational perspective and for the ambient concentrations near significant H2S sources and in background urban areas. The monitoring infrastructure needs to be improved to allow continuous surveillance to ensure reliable databases that support research regarding the health effects of H2S across the concentrations occurring in the urban environment.

In the latest years, the need of new technologies in the industrial environment has increased due to the need of a more cost efficient, resilient, and sustainable production process. One of the main issues that is addressed in this research work is the lack of a technology that allows prediction and prevention of the breakdowns of a production line using digital models and artificial intelligence to take the best decisions based on real-time data.
This paper presents a method for collecting data from the production line and feed these data to a database used by the Digital Twin model created in Matlab Predictive Maintenance Toolbox in which, based on this data, a decision about the maintenance activities required will be taken. This approach generates significant value by assisting maintenance engineers in pinpointing the precise timing for equipment maintenance. This capability directly contributes to reducing production line downtime and minimizing failures. Also, the Digital Twin model can be used to enable and test adjustments to the parameters of the production line equipment in order to determine the impact of this changes of the production process without interfering with the production process itself.
STUDY ON THE RECOVERY OF THERMAL ENERGY FROM TECHNOLOGICAL FLOWS IN THE COKING PLANT

In this paper, the current heat recovery system from delayed coking in a Romanian refinery is analyzed, the current system is simulated, and an additional heat recovery variant is proposed and simulated. Currently, the raw material is preheated with the following hot streams: light and heavy diesel (LDO and HDO) as final products of the plant and recirculated heavy diesel (RDO). After preheating the raw material, the final temperatures of the hot process streams indicate a thermal energy reserve that can be harnessed. Hot technological flows, after preheating the raw material, pass through air coolers, thus a large part of the thermal energy is lost in the environment. Since the temperature level of the hot technological flows is quite high after the preheating of the raw material - the outlet temperatures LDO is 167°C, HDO is 277°C and RDO is 245°C - the paper proposes two options for recovery of the heat from technological flows that have a reserve of thermal energy, obtaining low-pressure saturated steam. The simulation of raw material preheating systems, the actual and the proposed variant, were made with the PRO/II software.

Extended Aerosol Optical Depth (AOD) time series analysis in an Alpine Valley: A Comparative Study from 2007 to 2023
Authors: Wagner Jochen , Ubele Alma Anna , Schenzinger Verena , Kreuter Axel
Published: January 2024

Abstract. This study presents an extended analysis of aerosol optical depth at 501 nm (AOD) in the Alpine valley of Innsbruck, Austria, from 2007 to 2023, and offers a comparative analysis with the Alpine station of Davos, Switzerland. AOD is derived from ground-based sunphotometer measurements of direct spectral irradiance during daytime. The Davos Station is part of the AErosol Robotic NETwork (AERONET), a global network providing high quality, ground based remote sensing aerosol data and complies with the relevant requirements. The Innsbruck station does not belong to AERONET, but the AOD retrieval algorithm is very similar. Building upon previous research conducted until 2012, the presented study aims to provide a comprehensive understanding of the long-term trends and seasonal variations in aerosol characteristics in Central Alpine regions. We observed the typical mid latitude annual cycle with a maximum in July and a minimum in December. The AOD trends per decade for both stations are declining, -27.9 x 10−3 for Innsbruck and -9.9 x 10−3 for Davos.
Scaling artificial heat islands to enhance precipitation in the United Arab Emirates

Published: January 2024

Abstract. Potential for regional climate engineering is gaining interest as a means of solving regional environmental problems like water scarcity and high temperatures. In the hyper-arid United Arab Emirates (UAE), water scarcity is reaching a crisis point due to high consumption and over-extraction and is being exacerbated by climate change. To counteract this problem, the UAE has conducted cloud-seeding operations and intensive desalination for many years but is now considering other means of increasing water resources. Very large “artificial black surfaces” (ABSs), made of black mesh, black-painted, or solar photovoltaic (PV) panels have been proposed as a means of enhancing convective precipitation via surface heating and amplification of vertical motion. Under the influence of the daily UAE sea breeze, this can lead to convection initiation under the right conditions. Currently it is not known how strong this rainfall enhancement would be or what scale of black surface would need to be employed. This study simulates the impacts at different ABS scales using the WRF-Noah-MP model chain and investigates impacts on precipitation quantities and underlying convective processes. Simulations of five square ABSs of 10, 20, 30, 40, and 50 km sizes were made on four 1 d cases, each for a period of 24 h. These were compared with a Control model run, with no land use change, to quantify impacts. The ABSs themselves were simulated by altering land cover static data and prescribing a unique set of land surface parameters like albedo and roughness length. On all 4 d, rainfall is enhanced by low-albedo surfaces of 20 km or larger, primarily through a reduction of convection inhibition and production of convergence lines and buoyant updrafts. The 10 km square ABS had very little impact. From 20 km upwards there is a strong scale dependency, with ABS size influencing the strength of convective processes and volume of rainfall. In terms of rainfall increases, 20 km produces a mean rainfall increase over the Control simulation of 571 616 m3 d−1, with the other sizes as follows: 30 km (∼ 1 million m3 d−1), 40 km (∼ 1.5 million m3 d−1), and 50 km (∼ 2.3 million m3 d−1). If we assume that such rainfall events happen only on 10 d in a year, this would equate to respective annual water supplies for > 31 000, > 50 000, > 79 000, and > 125 000 extra people yr−1 at UAE per capita consumption rates. Thus, artificial heat islands made from black panels or solar PV offer a means of enhancing rainfall in arid regions like the UAE and should be made a high priority for further research.

Abstract. In this paper, we explore different prognostic methods to account for skin sea surface temperature diurnal variations in a coupled ocean-atmosphere regional model of the Mediterranean Sea. Our aim is to characterize the sensitivity of the considered methods with respect to the underlying assumption of how the solar radiation shapes the warm layer of the ocean. All existing methods truncate solar transmission coefficient at a constant warm layer reference depth; instead, we develop a new scheme where this latter is estimated from a chlorophyll dataset as the e-folding depth of solar transmission. This allows spatial and temporal variations of the warm layer extent to depend on seawater transparency. Comparison against satellite data shows that our new scheme improves the diurnal signal especially during winter, spring, and autumn, with an averaged bias on monthly scales year-round smaller than 0.1 K. In April, when most of the drifters measurements are available, the new scheme mitigates the bias during nighttime, keeping it positive but smaller than 0.12 K during the rest of the monthly-averaged day. The new scheme implemented within the ocean model improves the old one by about 0.1 K, particularly during June. All the methods considered here showed differences with respect to objectively analyzed profiles confined between 0.5 K during winter and 1 K in summer for both the eastern and the western Mediterranean regions, especially over the uppermost 60 m. Overall, the surface net total heat flux shows that the use of a skin SST parametrization brings the budget about 1.5 W/m2 closer to zero on an annual basis, despite all simulations showing an annual net heat loss from the ocean to the atmosphere. Our “chlorophyll-interactive” method proved to be an effective enhancement of existing methods, its strength relying on an improved physical consistence with the solar extinction implemented in the ocean component.
Quantifying cascading uncertainty in compound flood modeling with linked process-based and machine learning models
Authors: Muñoz David F. , Moftakhari Hamed , Moradkhani Hamid
Published: January 2024

Abstract. Compound flood (CF) modeling enables the simulation of nonlinear water level dynamics in which concurrent or successive flood drivers synergize, producing larger impacts than those from individual drivers. CF modeling is yet subject to four main sources of uncertainty including (i) initial condition, (ii) forcing (or boundary) conditions, (iii) model parameters, and (iv) model structure. These sources of uncertainty, if not quantified and effectively reduced, cascade in series throughout the modeling chain and compromise the accuracy of CF hazard assessments. Here, we characterize cascading uncertainty using linked process-based and machine learning (PB-ML) models for a well-known CF event, namely Hurricane Harvey in Galveston Bay, TX. For this, we run a set of hydrodynamic model scenarios to quantify isolated and cascading uncertainty in terms of maximum water level residuals, and additionally, track the evolution of residuals during the onset, peak, and dissipation of Hurricane Harvey. We then develop multiple-linear regression (MLR) and PB-ML models to estimate the relative and cumulative contribution of the four sources of uncertainty to total uncertainty over time. Results from this study show that the proposed PB-ML model capture “hidden” nonlinear associations and interactions among the sources of uncertainty, thereby outperforming conventional MLR models. Model structure and forcing conditions are the main sources of uncertainty in CF modeling and their corresponding model scenarios, or input features, contribute to (56 %) 49 % of variance reduction in the estimation of (maximum) water level residuals. Following these results, we conclude that PB-ML models are a feasible alternative for quantifying cascading uncertainty in CF modeling.
Spatial distribution of vertical density and microstructure profiles in near-surface firn around Dome Fuji, Antarctica

Published: January 2024

Abstract. To better understand the near-surface evolution of polar firn in low-accumulation areas (<30 mm w.e. yr−1), we investigated the physical properties – density, microstructural anisotropy of ice matrix and pore space, and specific surface area (SSA) – of six firn cores collected within 60 km of Dome Fuji, East Antarctica. The physical properties were measured at intervals of ≤0.02 m over the top 10 m of the cores. The main findings are (i) a lack of significant density increase in the top ∼4 m, (ii) lower mean density near the dome summit (∼330 kg m−3) than in the surrounding slope area (∼355 kg m−3) in the top 1 m, (iii) developments of a vertically elongated microstructure and its contrast between layers within the top ∼3 m, (iv) more pronounced vertical elongation at sites and periods with lower accumulation rates than those with higher accumulation rates, (v) a rapid decrease in SSA in the top ∼3 m, and (vi) lower SSA at lower-accumulation sites, but this latter trend is less pronounced than that of microstructural anisotropy. These observations can be explained by a combination of the initial physical properties on the surface set by wind conditions and the metamorphism driven by water vapor transport through the firn column under a strong vertical temperature gradient (temperature gradient metamorphism, TGM). The magnitude of TGM depends on the duration of firn layers under the temperature gradient, determined by the accumulation rate; longer exposure causes a more vertically elongated microstructure and lower SSA. Overall, we highlight the significant spatial variability in the near-surface physical properties over the scale of ∼100 km around Dome Fuji. These findings will help us better understand the densification over the whole firn column and the gas-trapping process in deep firn and possible difference in them between existing deep ice cores and the upcoming “Oldest-Ice” cores collected tens of kilometers apart.

Challenges and Opportunities Experienced by Service Providers at Homeless Shelters in Tshwane, South Africa During the COVID-19 Pandemic
Authors: Mathole Rivonia , Ross Eleanor
Published: January 2024

While the coronavirus disease of 2019 (COVID-19) pandemic exerted a devastating impact on all members of society, it highlighted the worsening inequalities experienced by marginalised groups such as people experiencing poverty and homelessness in South Africa. The pandemic also exacerbated the multiple demands and stressors of service providers working in homeless shelters. Hence, the study examined the experiences of service providers in terms of challenges and opportunities derived from working at homeless shelters in Tshwane, South Africa, during the hard lockdown from 27 March to 30 April 2020. Guided by a qualitative approach, five service providers were interviewed online. Thematic analysis revealed organizational challenges, such as a lack of knowledge and preparedness regarding disaster management, while client challenges included getting service users to adapt to living with rules. Organizational opportunities included the opportunity for the organization to conduct research, while personal opportunities included the learning experience of working with a vulnerable population during an unprecedented pandemic. Findings highlight the need for programmes to support the wellness needs of service providers and the development of a national policy on homelessness.

Badania identyfikacyjne dotyczące podpisów biometrycznych od kilku lat na dobre weszły w przedmiotowy zakres ekspertyzy pismoznawczej. Artykuł przedstawia teoretyczne możliwości dalszego rozszerzenia pola wykorzystania podpisów biometrycznych, np. na dokumenty wykonywane w kancelariach notarialnych czy prywatne testamenty sporządzane na urządzeniach mobilnych wyposażonych w aplikację rejestrującą parametry biometryczne składanych na tych dokumentach podpisów. O ile badanie podpisów z dokumentów notarialnych nie powinno nastręczać istotnych problemów badawczych, o tyle w przypadku testamentów mogą się one pojawić, zwłaszcza w sytuacji zachodzącego podejrzenia o składanie podpisu ręką tzw. podtrzymywaną lub ręką wodzoną.Z przeprowadzonych przez autorów artykułu eksperymentów wynika, że cechy podpisu biometrycznego składanego:ręką podtrzymywaną przy zbieżnych parametrach grafometrycznych z autentycznymi podpisami testatora mają zgodne charakteryzujące te podpisy parametry biometryczne; ręką wodzoną przy zbieżnych lub różnych w stosunku do oryginalnych podpisów testatora parametrach grafometrycznych mają zdecydowanie różne charakteryzujące te podpisy parametry biometryczne.Zaobserwowano także, że parametry podpisu biometrycznego wykonanego ręką wodzoną są analogiczne z cechami biometrycznymi podpisów porównawczych wykonanych przez fałszerza na nazwisko testatora. Wyniki eksperymentu pozwoliły także na weryfikację dotychczas funkcjonujących w klasycznej ekspertyzie pisma zjawisk opisujących podpisy wykonane ręką wodzoną i podtrzymywaną wykonanych na podłożu papierowym.
Sustentabilidade
Authors: Oliveira de Souza Romênia
Published: January 2024

Na língua portuguesa, coisas diferentes estão contempladas no conceito de desenvolvimento sustentável. A discussão sobre desenvolvimento, em si, há muito tempo, levanta questionamentos críticos sobre sua impossibilidade, dada a estrutura inerente ao capitalismo e às desigualdades que o sustentam. Com o qualificativo sustentável, o que deveria ser a solução para problemas provocados pela busca do desenvolvimento a qualquer custo, torna-se uma imensa contradição. A publicidade, os governos, as empresas se apropriam deste termo com a intenção de disseminar uma imagem pública de atores comprometidos com tal desenvolvimento. Contudo, não raras vezes, seus porta-vozes falam, por exemplo, em exploração sustentável da natureza, algo expressamente impossível. Se há exploração, não pode ser sustentável. Estes atores são conscientes disto. Escrever um artigo para esclarecer sobre o assunto é oportuno. E eu penso, principalmente, em estudantes, pesquisadores, atores sociais que, verdadeiramente, desconhecem as nuances e críticas existentes no debate corrente. Que se encontram confusos, como um dia eu estive quando comecei a estudar sobre o assunto. Após pesquisa bibliográfica, reuni seis modelos de desenvolvimento sustentável a partir de racionalidade econômica-teórica-instrumental-tecnológica, da economia ambiental neoliberal e da geopolítica do desenvolvimento, analisando-os criticamente: a sustentabilidade retórica; ao anterior, outro modelo com acréscimo de ‘melhorias’ culturais e neuroplástica; o neocapitalista; do capitalismo natural; a economia verde; e o ecossocialismo. Todos eles são contraditórios, embora bastante difundidos. Em contraposição, sob a chamada racionalidade ambiental, compilei as contribuições de seis cosmologias e de dois modelos de sustentabilidade, há muito praticados, embora não o sejam contemplados sob esta perspectiva: o zen budismo; o taoísmo; o confucionismo; as filosofias africanas (destaque para categoria ontológica do ubuntu); o sufismo; as filosofias do bem-viver; a bioeconomia e o ecodensenvolvimento; e a economia solidária. Seguindo Enrique Leff, utilizo apenas o substantivo sustentabilidade para diferenciá-lo de desenvolvimento sustentável, evidenciando o comprometimento com valores outros que não são contemplados pelo conceito economicista. E rompendo, sempre que possível, com as conotações negativas que o nome desenvolvimento traz consigo. Ao final, acredito ter elucidado e desmistificado o que é a tal sustentabilidade.

Resumo: O estudo que você vai ler neste artigo é o retrato da realidade em muitos espaços no Brasil. Oriundo da conjuntura histórica de domínio e imposição por um lado, da humilhação e obediência por outro, a sociedade brasileira chega ao drama de vivenciar a polarização ideológica que presenciamos. No intuito de complementar os argumentos apresentados em um artigo publicado no ano de 2020, com o título: “O cenário político brasileiro e a polarização dos últimos tempos, o qual, justifica a importância desse estudo, temos como objetivo, falar nas contradições, ações e reações da sociedade, onde entram em jogo pensamentos opostos e uma sociedade que tem a sua maioria fadada ao anonimato, porque, culturalmente, sempre sofreu imposição e distorção de valores desde as origens coloniais. O estudo bibliográfico conta com referenciais que refletem sobre a realidade social brasileira, complementado por outros teóricos. Concluímos este artigo mostrando que a conduta oscilante no comando da sociedade é fruto da pressão imposta pelas forças dominantes que, na verdade, criam a polarização que condenam e, por essa razão, a resistência e o sonho de novas perspectivas. Esforçamos para ser objetivo e didático na proposta do novo estudo que merece ser ampliado, debatido nas bases da sociedade e esta é a razão de palavras-chave, como: contradição, ideologia, polarização e didática.

Authors: Iatchevici Vadim , Toca Alexei , Nitulenco Tatiana , Stroncea Aurel
Published: January 2024

Technological development is largely determined by technology transfer, which is conditioned by the absorption capacity of new technologies, and new technologies are deeply digitized technologies. Success depends on creating basic digital skills, both technical and human, developing digital infrastructure, ensuring accessibility to digital technologies. In the context of Industry 4.0 technologies, the efforts to design products with pronounced physical-cybernetic elements are important, but especially those aimed at creating digital twins, gradually moving from intermediate variants of digital model and digital shadow. Digital twin creation models refer to the life cycle with emphasis on its stages. The paper proposes a digital twin model based on the technological function, in which the modification of the properties is manifested by restructuring the internal functions of the operator, operand and interface. The central place in this model belongs to the interface, which reflects the multitude of physical-technical processes at different scales of macro, meso, micro analysis characteristic of objects and processes in machine building.

Theological Education in the Light of 2 Timothy 3:10-17: An Evaluation of Pastoral Ministry in Nigeria
Authors: Honesty Oke Monday
Published: January 2024

God’s calling of humankind for the work of the ministry is as old as the beginning of the world, but God does not call a man without a period of training known today as theological education. Unfortunately, these days, there is an emergence of anti-intellectualism in the pastoral ministry, where many pastors go into ministry without a basic token of theological training. Also, many seminarians attend the seminary for formality purposes, just to acquire a certificate for their licensing and ordination; they jettison theological and divinity courses like Greek, Hebrew as well as Dogmatics, insisting that success in pastoral ministry does not lie on theological education. However, this research aims at evaluating the necessities of theological education in the 21st century Nigeria pastoral ministry on one hand and the ephemerality of anti-intellectualists and impostors in ministry on the other hand, drawing inference from 2 Timothy 3:10-17. The research adopts a lexico-grammatical exegetical method of data analysis in order to achieve its aim, using primary and secondary sources of data collections. The research claims that the reason there is a multiplicity of pastors in Nigeria presently, who are not successful in the ministry is because many churches and individuals take theological education for granted. Thus, it recommends that churches should take theological education seriously and those who disdain and undermine theological education should refrain from that, so as to have successful pastoral ministry in Nigeria.
Conditional Clauses In Shupamem

Published: January 2024

This paper describes the structure of conditional clauses in Shupamem, a Grassfield Bantu language spoken in the West region of Cameroon. The analysis of the empirical data collected from selected Shupamem native speakers revealed that Shupamem makes use of discontinuous morphemes to mark conditional constructions. The structure of these morphemes depends on (i) the branching configuration between the conditional clause and the main clause, and (ii) the tense feature of the conditional clause’ finite verb. The structure Cond.<MC involves the discontinuous morpheme kʉ̀......mbʉ́ whereby kʉ̀ “if” is inserted between the subject and the verb of the conditional clause, while mbú “then” introduces the main clause. The tense features of the conditional clauses are marked by the corresponding tense morphemes. In the second alternative of the Cond.<MC structure, the conditional clause is introduced by à pə̀ jʉ́ə (roughly translated as “is it that”) and closed by nə́, and the main clause is introduced by mbú. In MC<Cond. structures, on the contrary, no morpheme introduces the main clause. The conditional clause displays a relative clause-like structure introduced by the morpheme mə̀ jʉə́ “if” and closed by the definitizer nə́. Finally, Shupamem conditionals are classified into three types (general truth, possible actions, and imaginary actions), based on their semantic interpretations.

Published: January 2024

OBJECTIVE: Work stress is a serious problem for employees in primary education. This study evaluates the effects of a work stress prevention approach on emotional exhaustion and work stress determinants (job crafting behavior, quantitative and emotional demands, leadership, support, autonomy, team culture and feelings of competence), and the impact of implementation success (management commitment, employee involvement, communication during implementation) on these outcomes.

METHODS: A quasi-experimental study was conducted with an intervention group (4 schools, N=102 employees) and a control group (26 schools, N=656 employees) using questionnaires at baseline (T0), one-year (T1) and two-year (T2) follow-up. Multilevel mixed model analyses were performed to test effects of condition and implementation success on changes in emotional exhaustion and work stress determinants between T0 and T2 in the intervention and control group.

RESULTS: No effect were found for emotional exhaustion. Improvement of quality of leadership between T0 and T2 was significantly larger in the intervention compared to the control group. Additionally, implementation success was associated with a decrease in unnecessary demands and an increase in quality of leadership, team culture and job crafting behavior.

CONCLUSIONS: This study shows no direct effect of the approach on emotional exhaustion, but it does show beneficial effects on quality of leadership. Additionally, results suggest that, when successfully implemented, the approach also has beneficial effects on other work stress determinants (ie, job crafting behavior, unnecessary demands and team culture). Results indicate that – if implemented successfully – the organizational-level intervention has the potential to improve the psychosocial work context.
Domain Decomposition Method for a Class of Singularly Perturbed Differential-Difference Equations
Authors: D. Kumara Swamy Et al.
Published: January 2024

In the current research, a domain decomposition approach is created to solve a class of differential difference equations with singular perturbations. By establishing a terminal point, the original problem's domain is split into two distinct parts, the inner region, and the outer region. The reduced problem is used to derive an implicit boundary condition at the terminal point, and a special finite difference approach is then used to solve the outer region problem. Applying a particular finite difference technique, the inner area problem is solved by using a stretching transformation and the known value at the terminal point from the outer solution. The method's convergence analysis is also presented. Three model examples are tested, and it is discovered that the numerical solution closely resembles the precise/available solution.

Published: January 2024

The CloudIoT is an extensive network that hosts several IoT gadgets and apps. This comprises the servers and the storage space required for real-time processing and operations. For commercial purposes, data gathered by IoT devices may be safely saved and handled on the cloud. CloudIoT allows for the scalable distribution of software. IoT devices capture information using built-in sensors and monitors. After collection, it is sent to a central location where data from other Internet of Things devices is kept. Cloud storage offers a scalable, cost-effective alternative for maintaining and administering IoT data—the capacity to grow or change quickly. More and more Internet of Things devices means a greater need for data storage and processing capacity. The cloud computing solution is scalable and adaptable enough to meet these shifting requirements.  Hence, this paper proposes a nonlinear time series analysis for enhancing anomaly detection in cybersecurity based on Cloud-Internet of Things (CloudIoT-CS). Statistics like precision and positive and negative results are considered part of assessing the suggested methodology by comparing it against conventional anomaly detection techniques. The study also looks at the system's resistance to hostile assaults, guaranteeing its efficacy in practical cybersecurity settings. This study's findings provide a holistic and flexible approach that accounts for the unique challenges posed by CloudIoT settings. As well as improving the precision of anomaly identification, integrating nonlinear time series evaluation with CloudIoT creates a scalable and robust framework for protecting vital systems from ever-evolving cyber threats.
Optimizing Nonlinear Control Strategies for Autonomous Vehicles
Authors: Shwetabh Kumar
Published: January 2024

Maximizing the effectiveness of nonlinear control techniques (NCT) is crucial for the broad acceptance and smooth integration of autonomous vehicles. Navigating the intricacies of real-world settings, boosting vehicle stability, and enhancing overall performance are all greatly impacted by these tactics. For manufacturers to successfully deploy autonomous cars in environments that are both dynamic and unpredictable, it is crucial to strike a balance between rigid control and flexibility. Autonomous vehicles confront a number of obstacles when trying to optimize nonlinear control systems, including changing road conditions, unpredictable traffic, and the requirement to make decisions in real-time. Because of the complexity of these problems, traditional control methods are frequently not up to the task, thus one need to find new ways to make control strategies more resilient and flexible. A Nonlinear Control Optimization Framework (NCOF) is suggested in this research; it makes use of adaptive control mechanisms, high-level optimization methods, and machine learning approaches. NCOF is engineered to enhance the vehicle's performance in a variety of situations by continuously adapting and optimizing control parameters using environmental data and real-time feedback. Beyond conventional navigation, the NCOF finds use in situations including emergency response, complicated urban surroundings, and bad weather. Improved decision-making, navigating, and passenger safety in a variety of situations are all outcomes of NCOF's optimization of nonlinear control techniques for autonomous cars. Thorough simulation assessments are carried out across several virtual scenarios to verify the efficacy of the suggested NCOF. Displaying the flexibility, stability, and efficacy of NCOF in various contexts, the simulations evaluate the optimal nonlinear control schemes' effectiveness in contrast to conventional methods.

Authors: Chandrakant Deelip Kokane Et al.
Published: January 2024

Nonlinear analysis is an essential area of signal and communication engineering. Many different kinds of nonlinear analysis can be used in this study. Linear signal processing techniques had previously struggled to accurately capture complex data pattern and communication signals. However, the development of non-linear analysis is a game-changing advancement since it provides a solid framework for understanding and manipulating these complex and non-trivial dynamics. In order to understand the behaviour of a wide variety of signals, from financial market trends to biological and environmental data, non-linear techniques are essential in signal processing. Improved understanding of system behaviour and predictive models may result from the use of such techniques to extract complex data patterns that are not often used. Non-linear approaches also contribute to the development of image and video processing by easing the development of advanced compression, tracking, and object recognition algorithms. Non-linear analysis is crucial in communication engineering as it aids in comprehending and optimising the flow of information across various channels. A greater understanding of signal distortion is made possible by the nonlinear perspective, which makes it possible to build reliable communication systems that can withstand interference and noise. By facilitating the creation of sophisticated modulation systems, adaptive equalisation methods, and error control coding, it raises the communication networks' dependability and effectiveness. Designing complex systems that can handle the complexities of today's data and communication demands is made possible by the paradigm-shifting synergy of nonlinear analysis, signal processing, and communication engineering. This abstract highlights the role that nonlinear analysis plays in transforming various fields and highlights how it can be used to solve changing problems related to information comprehension, processing, and transmission in a technologically sophisticated world.
