In contemporary times, nations like Sri Lanka are actively enhancing their efforts to improve the life expectancy of their citizens, with a strong focus on public health. The relationship between health and life expectancy is pivotal. Poor health conditions tend to diminish life expectancy, while robust health measures tend to extend it. Within the context of health, birth and death events are of paramount importance. Birth represents the genesis of life, enabling individuals to contribute to future generations and the overall population's expansion. It's the cornerstone of life on our planet. However, modern times have witnessed challenges in pregnancy and childbirth, with some infants not surviving the prenatal period or being born with health complications. Consequently, there is a pressing need to present a solution that can contribute to the betterment of maternal and infant health, ultimately augmenting Sri Lanka's life expectancy. The proposed solution is the development of a mobile application, encompassing features such as a Nutrition Predictor, Medicine Effect Predictor, AI chatbot, and Baby Status Predictor. This innovative application aims to address the complex issues surrounding pregnancy and childbirth, with the overarching goal of improving the nation's life expectancy. © 2024 IEEE.

The key objective of the connected and automated vehicle (CAV) platoon control problem is to regulate CAVs' position while ensuring stability and accounting for vehicle dynamics. The unconstrained version of this problem has thoroughly been investigated in the literature. We elaborate on the constrained version of this problem to theoretically mitigate the two shortcomings of the unconstrained counterpart: (i) the synthesis of unrealistic high-gain control parameters due to the lack of a systematic way to incorporate the lower and upper bounds on the control parameters, and (ii) the performance sensitivity to the communication delay due to inaccurate Taylor series approximation. The former is mitigated via a systematic parameterization of the control gains based on the Hurwitz stability criterion. The latter is mitigated by taking advantage of the well-known Padé approximation. The usefulness of the proposed theoretical results is assessed by performing numerous numerical simulations. Furthermore, a thorough comparative analysis is empirically conducted between the constrained and unconstrained versions of the CAV platoon control problem with application to the mixed vehicular platoon. Modern transportation systems will benefit from the proposed CAV controls by effectively attenuating the stop-and-go disturbance - a single cycle of deceleration followed by acceleration - amplification throughout the mixed vehicular platoon as it will potentially reduce collisions. © 2024 IEEE.

Procedia Computer Science 2025年 253卷 1860-1869页

作者： Christian Lehner Oliver Kosak Hella Ponsar Wolfgang Reif Institute for Software & Systems Engineering University of Augsburg Universitätsstraße 2 86159 Augsburg Germany

In the era of Industry 4.0 and individualized mass customization, the demand for adaptable manufacturing systems is paramount. Therefore, assembly plans used in such systems must also allow a high degree of flexibility to adapt to changing requirements and conditions. At the same time, they must still guarantee the successful execution of the assembly process. In this paper, we present a novel approach to modeling assembly plans in the context of an ongoing, larger project in which we intend to implement flexible manufacturing in a real production cell. In our assembly plans, we specifically emphasize flexibility regarding the order of assembly steps, the allocation of appropriate teams of robots to execute these steps with applicable parts, and the ability to respond to failures in the system. We present a comprehensible modeling of flexible assembly plans, accompanied by the semantics of Petri nets, illustrated by example, and comparatively evaluated against other approaches.

Optical power transfer and optical data communication are versatile technologies with numerous applications, utilizing both fiber-coupled systems and free-space optical links. The integration of these technologies into a single link simplifies system design while combining the benefits of simultaneous power delivery and data communication for receiving systems. This study evaluates various applications by examining their power demands, data rate requirements, and external factors such as link medium and operational distance. A graphical representation is provided to facilitate application targeting for specific groups, dictating the needed system requirements. Three key application clusters are identified: A) Internet of Things connectivity (free-space, ~10 m, 0.2-10 W), B) network infrastructure (fiber/free-space/underwater, 10 m – 1 km, 10-100 W), and C) moving objects (free-space, 100 m – 500 km, 1-10 kW). © 2025 SPIE.

The holistic application of data-driven value-adding services (DDSs) to shop-floor assets (SFAs;e.g. equipment, machines, components) is a major obstacle, particularly for small and medium-sized enterprises (SMEs): Due to the high complexity and required expertise in various disciplines. It is necessary to i) select suitable DDSs for a relevant component in production, ii) provide data for their training, iii) deploy the DDSs in the given IT/OT infrastructure, and iv) setup data-streams between SFAs, DDSs, and dashboards. Currently, many companies are implementing flagship projects that go through the necessary steps for individual components, but these isolated solutions are not scalable due to the need for manual intervention. This paper describes how to completely automatize the four steps and their consolidation in a scalable Industry 4.0 one-stop-shop solution. To achieve this goal, each asset is equipped with an Asset Administration Shell (AAS) that specifies, in particular, the represented asset's capabilities, the data required to apply such a capability and the data generated by a capability. Based on the AASs of SFAs, DDSs, and computing resources (CRs), a matching service suggests automatically which DDSs would add value to which SFAs and, for each SFA-DDS match, in which CR to deploy the DDS. A trade fair demonstration provides strong support for the statements made: The one-stop-shop solution including the automatic matching greatly simplifies the application of data-driven services and, in some cases, even makes it possible at all. © 2024 IEEE.

The operation of innovative process plants like offshore Power-to-X platforms that produces green hydrogen and derivatives poses critical risks for the environment and personnel as well as the operating company. This is due to the high system complexity, the energies and materials used and the associated high investment and maintenance costs. To keep these risks low, the occurrence of corresponding critical cases must be avoided, for which reason the personnel must be optimally assisted and enabled in their tasks during all phases of the platform life cycle. We have therefore enhanced a digital twin presenting a teleoperation platform that allows modular use of assistance systems. As a proof of concept, an alarm management system is presented. © 2024 The Authors.

Vegetation on traffic routes is not only an aesthetic problem. On railways and roads, it poses a safety risk by reducing the elasticity of track beds or damaging road surfaces. Therefore, complex weed management is indispensable. This is currently achieved mainly through the extensive use of herbicides or manual removal, which pollutes the environment and incurs high costs. These negative impacts can be mitigated by an automated vegetation detection which allows efficient, targeted treatment and preventive long-term monitoring. A reliable method to achieve this is to exploit the characteristic spectral fingerprint of vegetation: Chlorophyll shows a high reflectivity in the green and infrared spectral region while strongly absorbing red and blue light. We present such a visual monitoring system comprising multiple cameras and an active illumination which is employed on railroads. The individual cameras address different spectral regions and are superimposed through a position-synchronized triggering to obtain a multi-spectral image. Multi-pixel binning greatly extends the dynamic range of the cameras and, in combination with active illumination and high-speed dark frame recording, allows operation during day and night without degradation from ambient light conditions. The system achieves about 5 mm effective resolution and can operate up to a speed of 100 km/h. This is possible through embedded real-time pre-processing and data reduction already in the camera units. A processing delay of less than 100 ms is the consequence which allows targeted actuation of weed-treatment methods (e.g., spray nozzles) during movement. In combination with GNSS-sensors geo-referenced documentation of the coverage rate is possible. © 2023 SPIE.

Home care of people with dementia (PwD) is mainly organized and carried out by non-professional family caregivers, who struggle to interpret the needs of PwD correctly and are confronted with the challenging behavior of their relatives. Although support services for family caregivers are widespread in Germany, they are rarely used due to the fact that information is poorly organized and relatives are faced with a flood of disorganized, outdated, and confusing content. Due to the technical development of chatbot technologies (ChatGPT), chatbots gain more and more relevance. Based on the new technological possibilities, we developed an online communication and service platform with an integrated chatbot within the eDEM-CONNECT project, with the aim of making structured and easily understandable information accessible for family caregivers. This work focuses on the development of a chatbot pipeline that has broad domain knowledge through a provided ontology on the topic of agitation of PwD. This allows the chatbot to provide relevant and peer-reviewed information to family members. In our approach, a patient history is first taken based on several diagnostic questions so that relevant information can be output in a later step. For this purpose, we demonstrate that agitations in natural language can be correctly recognized by the used BERT model and that our developed chatbot is able to select further diagnostic questions based on the predictions of a Markov logic network. © ICST institute for Computer Sciences, Social Informatics and Telecommunications engineering 2024.

A multi-agent approach with verifiable and data-sovereign information flows for decentralizing redispatch in distributed energy systems

引用

Energy Informatics 2025年第1期8卷 1-27页

作者： Heess, Paula Holly, Stefanie Körner, Marc-Fabian Nieße, Astrid Radtke, Malin Schick, Leo Stark, Sanja Strüker, Jens Zwede, Till Branch Business and Information Systems Engineering Fraunhofer FIT Wittelsbacherring 10 Bavaria Bayreuth95444 Germany OFFIS - Institute for Information Technology Escherweg 2 Lower Saxony Oldenburg26121 Germany FIM Research Center University of Bayreuth Wittelsbacherring 10 Bavaria Bayreuth95444 Germany

The need to harness the flexibility of small-scale assets for system stabilization, including redispatch, is growing rapidly with the increasing prevalence of distributed generation, such as photovoltaic systems and heavy loads, in particular heat pumps and electric vehicles. Integrating these resources into the redispatch process presents special requirements: On the one hand, building trust with the owners of such assets requires privacy and a reasonable degree of autonomy and engagement. On the other hand, besides the system’s scalability and robustness, the verifiability and traceability of provided data are essential for grid operators who depend on the reliable provision of redispatch services. To date, research and practice have encountered significant challenges in defining a system that enables the inclusion of decentralized flexibilities while satisfying necessary requirements. To that end, we present a novel conceptual system design that addresses these challenges by combining a multi-agent system (MAS) approach with verifiable information flows through digital self-sovereign identities (SSIs) and Zero-Knowledge-Proofs (ZKPs). Single agents, as edge devices, operate locally and autonomously, respecting customer preferences, while MAS provide the ability to design robust, reliable, and scalable systems. SSI enables agents to manage their data autonomously, while ZKPs are used to protect users’ privacy through selective data disclosure which allows the verification of the correctness of information without disclosing the underlying data. To validate the feasibility of this design, a case study is included to demonstrate the functionality of key sub-processes, such as baseline optimization, aggregation, and disaggregation, in a realistic scenario. This case study, supported by a prototype implementation, provides initial evidence of the concept’s soundness and lays the groundwork for future evaluation through extensive simulations and field testing.

Twitter has been observed to be one of the essential data resources for dependable event accreditation. In any case, Twitter-based event affirmation structures can't guarantee assessment concerning their attestation results. Talk statement has been locked in starting late to enable liberal event Recognition. This problem is not yet evident in light of the assumption that most people tend to think that they have a specific limit to the data on Twitter that have frames based on events based on Twitter. Current appraisals see new pieces by seeing and looking at the significant psychological aspects of hitting the details on Twitter. No matter, the scale of the visual cues can be well established, with the intention that it is essential to design an integrated Twitter experiment with another set of extensible data resources to rectify this problem. The problem is the processes by which you should wholeheartedly investigate all converted data because it has different data structures, transfer times, etc. This issue of address, the paper proposes a framework for evaluating the use of Twitter-based events and examines two types of data resources for the reliability of impact testing. Our framework uses the resultant of the request obtaining by various events and relevant to the articles on it. This paper has improved the cleaning test with the proposed process how the integrity estimation of twitter based event can be recognized with the help of group of analyzed data. The evaluation indicates that the proposed system provides visible high-level testing events and a variety of low-level testing events. © 2024 IEEE.
