The aim of this study is to support local utilities in implementing the most beneficial regional Power-to-X projects (technologies for utilizing surplus electricity). In this learning paper, we explore the question: What are the most economically viable PtX business cases for local utilities in an urban setting? To this end, we provide an overview of possible PtX pathways and analyze the situation based on a scenario for the transformation of the energy sector in the city of Wuppertal. Based on this, policy recommendations are formulated to drive forward a low-risk and sustainable transformation of the energy sector and to remove economic and technical barriers. It is shown that socio-economic factors and the acceptance of society must also be taken into account in order to understand the overall situation and ensure the success of the energy transition. The learning paper is therefore also a plea for a holistic and interdisciplinary approach. [ABSTRACT FROM AUTHOR]

Currently, the growth of information technology is rapidly evolving alongside the journey of a business entity, as seen in public accounting firms facing demands to effectively utilize technology to enhance efficiency, productivity, and service quality. Identifying several challenges that may arise in the implementation of information technology strategies, including information security issues, investment costs, complex system integration, and organizational cultural challenges, public ac- counting firms are advised to pay attention to specific aspects in designing and implementing information technology strategies, such as selecting appropriate technology, employee training, and periodic performance evaluation, which are also necessary. Thus, by adopting the right information technology strategy, public accounting firms can improve their operational effectiveness, enhance client satisfaction, and strengthen their competitive position in the rapidly changing and competitive market. The IT Balanced Scorecard can serve as an effective framework in creating IT strategies because the distribution of strategies is evenly spread across all parts of the company, enabling the company to develop not only from a financial perspective but also from a non-financial one. The implementation of IT strategies is expected to help accounting firms achieve the goals, vision, and mission of the company and assist companies in implementing or planning IT strategies.

In response to the global pursuit of net-zero carbon emissions, the electrification of agricultural machinery is becoming a significant research and development trend. This study introduces the overall design of a 4 kW air compressor aimed at achieving a green vision for agricultural machinery. The design focuses on providing continuous and stable power and air output using a lithium-ion battery. Durability and cost-effectiveness are prioritized, with a particular emphasis on the Arduino system for integrating battery and motor systems to withstand harsh conditions and ensure ease of maintenance. A permanent magnet brushless motor was selected as the power source, paired with an optimized pulley to supply the proper torque to the air compressor. The system employs an Arduino-based feedback control sensor for air pressure regulation, ensuring energy efficiency. The primary energy source is a 48 V lithium iron phosphate battery, known for its high energy density and safety. The battery design focuses on system integration, addressing specific environmental discharge requirements. The embedded battery management system provides thermal and lifecycle parameter estimation, guaranteeing long-duration power supply and safe operation under various conditions. Unlike traditional fuel-driven systems, lithium iron phosphate batteries do not emit harmful gases, aligning with environmental standards. System integration testing demonstrated that the air pressure feedback control effectively meets the energy-saving requirements by digitally reducing power output as air accumulates in the chamber. Bench testing confirmed that the system performs as designed, achieving the desired results and advancing the goal of sustainable agricultural machinery. [ABSTRACT FROM AUTHOR]

Wireless communications play an important role in ensuring ease of access to shared electronic health records (EHR) across health service providers which is essential and significant for prompt patients' care, especially in cases of emergency medical conditions. With the need to support anytime, anywhere access to, potentially bandwidth hungry, medical records, electronic healthcare applications will continue to benefit from advanced wireless network technologies such as 5G and beyond. With sharing, it is crucial to provide patients with security and privacy guarantees, and allow them to certain control of access to their data. Existing solutions mostly assume that patients are available to authorize requests to access their EHR, which is impractical as the patient may be unconscious. This paper proposes a secure and privacy protecting protocol whereby the patient can pre-delegate the authorization for the access of his/her EHR. Our patient(user)-centric proposal combines Self-Sovereign Identity (SSI) concepts and model with Secure Multi-party Computation (SMPC) and Threshold Cryptography (TC) to enable secure identity and authorization verification. A block cipher encryption sharing approach is adopted for the threshold SMPC which extends the AES-GCM symmetric encryption model into a full-fledged cryptographic platform. Two mechanisms are implemented for the block cipher encryption, namely XOR and Cascade, and experiments are conducted to compare them. We conclude that the XOR mechanism can scale for larger thresholds, while Cascade performed better for a lower threshold (≤ 3). This paper also performs a threat analysis of the protocol and approach, and validates its correctness and complexity. We conclude that the approach can achieve the security and privacy protection of the patient's personal EHR, as well as the autonomy of the patient to control the authorization for the access and sharing.

The concept of the meta-universe is still in its early stages, but many leading tech companies have invested heavily in research and development for this technology. The development of meta-smart cities is a significant trend. In the meta-universe environment, integrating information systems is crucial for analyzing AI big data. Establishing an integrated platform for medical information systems is key to advancing information technology. In the context of the meta-universe, creating an efficient and unified integration platform to eliminate medical information silos and reduce system integration costs has become a pressing issue in medical informatization. This paper proposes a medical information system integration method based on an integration platform and utilizing cloud computing technology as a data center. The core business layer uses the integration software "Ensemble" as the integration platform. The underlying data center employs a Hadoop storage cluster with distributed data storage and parallel computing technology, and the existing scheduling algorithm is studied and analyzed to enhance the resource scheduling algorithm for medical small file data. The effectiveness of the algorithm is simulated and verified on an experimental platform, demonstrating improved efficiency in resource scheduling. [ABSTRACT FROM AUTHOR]

Photonic neuromorphic computing is a competitive paradigm to overcome the bottleneck of von Neumann architectures. Incoherent and coherent synaptic networks are two popular schemes realizing photonic weighting functions. Previous works have proved the distributed feedback (DFB) laser with an intracavity saturable absorber (DFB‐SA) can behavior like a spiking neuron. However, the compatibility with the incoherent synaptic architecture has not yet been demonstrated. Here the neuron‐like dynamics of a DFB‐SA laser subject to single‐wavelength and multiple‐wavelengths incoherent optical injections are experimentally demonstrated. The results show that, for the DFB‐SA laser subject to single‐wavelength incoherent injection, the neuron‐like dynamics including threshold, temporal integration, and refractory period are achieved. Besides, the range of injection wavelength that leads to a successful neuron‐like response is identified. For the DFB‐SA laser with four‐wavelength incoherent optical injection, the neuron‐like dynamics can also be achieved. In addition, the effect of wavelength interval is also considered. The logic XOR operation and Iris recognition tasks are successfully implemented. Furthermore, the feasibility of a cascaded system for the DFB‐SA lasers with four‐wavelengths incoherent optical injection is demonstrated. This work provides a feasible scheme for the system integration of photonic spiking neurons and incoherent synaptic networks. [ABSTRACT FROM AUTHOR]

Background: TPACK is a widely used framework for assessing teachers' competence in integrating technology in education. However, previous studies have shown varying interpretations of the relationship between TPACK elements. Qualitative studies that assess the manifestations of TPACK by examining the practices of pre‐service teachers are rare. Objectives: This study investigates technology integration in innovative physics teaching and learning materials designed by pre‐service teachers and the manifestation of technological pedagogical content knowledge (TPACK) in empirical cases. Methods: We qualitatively extracted the components of PCK, TPK, and TCK from the innovative physics teaching and learning materials developed by 22 pre‐service teachers in their fourth year at a teachers' college in South Korea. We scored them based on the new evaluation criteria established in this study. Results and Conclusions: Based on the materials, we identified three types of technology integration: Learning Materials Providing, Learning Activity Providing, and Virtual Experiments Creating. This study identifies teachers' level of TK and integrates it with TPACK expression. Results confirm the connection between TK and TCK and show that a strong PCK can serve as a basis for TPK. The TPACK expression pattern can help achieve balanced development of TPACK in teacher education. Lay Description: What is currently known about the subject matter: TPACK framework combines pedagogical, content, and technological knowledge in teachers' professional expertise.Despite TPACK's widespread use, studies showed varied interpretations of the relationships between its elements.TPACK measurement often relies on self‐assessment, lacking a total reflection of technology use in teaching.Few qualitative studies explore TPACK manifestations through pre‐service teachers' practices. What the paper adds to the currently known about: There are three types of technology integration: Learning Materials Providing, Learning Activity Providing, and Virtual Experiments Creating.The study found that pre‐service teachers in the virtual experiments creating type exhibit strong subject‐specific TPACK.In physics education, TK is essential and can be divided into the use of ICT and programming.The study correlates TK levels with TPACK expressions, resulting in five patterns based on PCK, TPK, TCK, and TK. The implications of study findings for practitioners: The study presents empirical evidence of TPACK manifestation in pre‐service physics teachers, focusing on TK.High programming TK has a significant impact on subject‐specific TPACK.The study confirms the TK‐TCK connection and highlights PCK's role in TPK.TPACK patterns can guide teacher education, fostering balanced development.

In this article, we summarize our views on the problem of consciousness and outline the current version of a novel hypothesis for how conscious minds can be generated in mammalian organisms. We propose that a mind can be considered conscious when three processes are in place: the first is a continuous generation of interoceptive feelings, which results in experiencing of the organism's internal operations; the second is the equally continuous production of images, generated according to the organism's sensory perspective relative to its surround; the third combines feeling/experience and perspective resulting in a process of subjectivity relative to the image contents. We also propose a biological basis for these three components: the peripheral and central physiology of interoception and exteroception help explain the implementation of the first two components, whereas the third depends on central nervous system integration, at multiple levels, from spinal cord, brainstem, and diencephalic nuclei, to selected regions of the mesial cerebral cortices.

Data-intensive applications executing on NVM-based storage systems experience serious bottlenecks when moving data between DRAM and NVM. We advocate for the use of the long-existing but recently neglected on-chip DMA to expedite data movement with three contributions. First, we explore new latency-oriented optimization directions, driven by a comprehensive DMA study, to design a high-performance DMA module, which significantly lowers the I/O size threshold to observe benefits. Second, we propose a new data movement engine, Fastmove, that coordinates the use of the DMA along with the CPU with DDIO-aware strategies, judicious scheduling, and load splitting such that the DMA's limitations are compensated, and the overall gains are maximized. Finally, with a general kernel-based design, simple APIs, and DAX file system integration, Fastmove allows applications to transparently exploit the DMA and its new features without code change. We run three data-intensive applications MySQL, GraphWalker, and Filebench atop NOVA, ext4-DAX, and XFS-DAX, with standard benchmarks like TPC-C, and popular graph algorithms like PageRank. Across single- and multi-socket settings, compared to the conventional CPU-only NVM accesses, Fastmove introduces to TPC-C with MySQL 1.13–2.16× speedups of peak throughput, reduces the average latency by 17.7–60.8%, and saves 37.1–68.9% CPU usage spent in data movement. It also shortens the execution time of graph algorithms with GraphWalker by 39.7–53.4%, and introduces 1.01–1.48× throughput speedups for Filebench. [ABSTRACT FROM AUTHOR]

This paper presents an all-digital and configurable resolution time-to-digital converter (TDC) with low process–voltage–temperature (PVT) sensitivity for light detection and ranging (LiDAR) applications. The proposed TDC offers configurable resolution, allowing it to provide an appropriate conversion resolution according to the system's requirements, thereby optimizing overall system performance. In addition, because the proposed TDC has high immunity to process–voltage–temperature (PVT) variations, it provides more stable time-converting results. The proposed design uses 0.18 μm CMOS technology, and the measurement results demonstrate a resolution ranging from 36 ps to 1193 ps, with a conversion range from 0.1 ns to 36 ns and an average error of 20.59 ps. Furthermore, the proposed TDC is implemented in an all-digital manner, making it highly suitable for system integration. [ABSTRACT FROM AUTHOR]

Nowadays a major energy transition aimed at cutting CO 2 emissions has begun, with the ambitious goal of drastically reducing the dependence on fossil fuels and promoting the use of renewable energy sources. In this context, energy storage systems play a key role in ensuring a stable, secure and time-aligned energy availability. Open sorption thermal energy storages (TESs) can contribute to such transition, since they are simple and cheap devices able to provide a hot airflow with a high energy density and to store energy for long time. In this work, open sorption TES systems operated with Zeolite 13 X are investigated with a focus on the integration in practical applications. First, the experimental analysis and modelling of the sole TES system is described. Then, the integration of the TES at system level is carried out. The analysis evidences that a significant reduction of storage capacity occurs if air humidification is necessary before the adsorption process or afterwards to keep adequate indoor comfort conditions for the occupants. For the exemplary case study considered, an energy density of 150 kWhm-3 can drop to 40 kWhm-3 in case of complete compensation of the adsorbed water through a humidifier. This paper provides useful guidelines for evaluating the performance of a TES integrated system in terms of specific energy and efficiency. It also identifies applications involving high latent loads (e.g., swimming pools, locker rooms) or for which low relative air humidity is required (e.g. interior of vehicles to prevent condensation on windows) as particularly beneficial for using a TES system.

Herein, the design, modeling, and validation of high‐flow, fluid‐driven, membrane valves tailored specifically for applications in soft robotic systems are described. Targeting the piping problem in hyper‐actuated soft robots, two fluid‐driven membrane valve designs that can admit flows of up to 871 mg s−1$871 \textrm{ } \textrm{ } \text{mg} \textrm{ } \left(\text{s}\right)^{- 1}$ while weighing less than 20 g$false$ are introduced. A mathematical model to predict fluid flow by representing the displacement of the membrane as a scalar quantity influenced by the balance of pressures applied across the valve's ports is established. The model incorporates six parameters with direct physical relevance, enhancing its usefulness in valve design and system integration. In an experimental validation, flow rates with deviations within 4% are predicted and the onset of flow is correctly identified with an error rate of less than 1%. In addition, applications of these valves for flow amplification and for the creation of a fluid‐driven oscillator are experimentally demonstrated. This research contributes to the advancement of soft robotics by providing a tool for designing, optimizing, and controlling fluid‐driven systems and it lays the groundwork for the future development of embedded, fluid‐controlled valve networks that can be used to realize hyper‐actuated soft robotic systems.

With the development of social economy, improvement of living standards and changes in lifestyle concepts, people's yearning for tourism has promoted the vigorous development of China's tourism industry. In order to meet the higher demands of tourists for tourism quality, the combination of tourism and rail transportation has emerged. At present, tourism rail transit is an emerging and relatively popular thing, but there is no corresponding classification, design, construction and acceptance standard. It is urgent to clarify the rail transit system suitable for different tourism resources for the selection and reference of construction units. This article analyzes the classification of tourist attractions, its demand and suitable rail transit system. It focuses on the adaptability of the cross seat monorail system in tourist rail transit, and concludes that the cross seat monorail system has a vehicle appearance that integrates with the environment, a transportation capacity that is suitable for tourist flow characteristics, a flexible vehicle composition, lightweight rail beam bridge structure, strong terrain adaptability, excellent environmental performance and engineering construction costs that meet investor requirements, making it a very suitable system for tourist rail transit. Finally, by analyzing the differences between cross seat monorail as a tourism rail transit and urban rail transit, it is proposed that research on cross seat monorail as a tourism rail transit should be conducted in the development of new vehicles, equipment configuration that matches the operational needs of tourism monorail, system integration, and formulation of tourism rail transit technical standards, providing reference for the promotion and implementation of tourism cross seat monorail transit in the future.

Heterogeneous integration is a key driver within the field of advanced electronic packaging. The realization of tomorrow's highly integrated electronic systems depends on the combination and compatibility of various integration technologies at the same hierarchy level. The adoption of novel bonding technologies for a cost-effective realization of multi-chiplet systems is a key aspect. Cu nanowire (NW) interconnects exhibit distinct advantages in terms of their scalability down to a few micrometers, the resulting joint properties and moderate demands with respect to the surface preparation, and the cleanliness of the bonding environment. No solder or flux is required for the bonding process, but the NW bumps still can compensate low height differences. The bonding process can be carried out near room temperature under ambient conditions. We demonstrate the technological possibility to integrate the Cu-NWs for a bump processing scheme including the Cu seed etching on 300 mm wafer for the first time. This paper focuses on the microstructure evaluation and the shear test of the formed Cu-NW interconnects fabricated under ambient conditions within a few seconds. The microstructure analysis shows the intact bonded interconnects and reveals high-resolution details of Cu-NWs. The shear strength of the formed interconnects varies between 4.6 MPa and 90.5 MPa depending on the bonding and annealing conditions. Overall, the results of this study highlight the potential of Cu-NW interconnects for future 3D heterogeneous system integration. [ABSTRACT FROM AUTHOR]

The hydrogen pressure typically increases to approximately 700-bar for storage in high-pressure tanks. Some industry applications use such a high-pressure hydrogen but some others need lower-pressure hydrogen where the pressure is reduced through pressure reduction valves. Some energy is lost during pressure reduction which would be significant in large-scale systems. A multi-level hydrogen storage can address this issue, where the hydrogen is stored at various pressures. This paper addresses an electricity-hydrogen nexus system integrated with multi-level hydrogen storage and solar PV sites. The designed system supplies electric and fuelcell vehicles at 3 different charging points including an electric vehicle charging station, fuelcell car refueling station, and fuelcell truck refueling station. The hydrogen is stored at 30, 350, and 700-bar pressure levels and each level feeds various users. The water electrolysis is employed to generate hydrogen at 30-bar pressure and 2 compressors increase the pressure to 350 and 700-bar. The cost function, defined as the daily energy cost, is optimized at $1045.65 per day. The water electrolyzer produces the most hydrogen during nighttime when electricity is inexpensive. Under normal operating conditions, the fuel cell is not utilized due to its low efficiency of about 60%. However, it serves as a backup resource in the event of a system outage, such as when the external grid fails, in hours 22 to 24. During this time, the fuel cell is activated and produces 154 kWh. • Multi-Level Hydrogen Storage. • Electricity-Hydrogen Nexus System Integration. • Optimized Hydrogen Production and Pressure Management. • Cost Optimization and Efficiency. • Backup Resource Utilization.

In a dynamic business environment, the convergence of Digital Transformation and Sustainable Transformation has emerged as a comprehensive strategy for companies seeking to thrive in the modern era. For this transformation to successfully develop, the appropriate conditions must be present to carry out a process of digitisation and sustainability. Therefore, this research aimed to identify the readiness level of companies established in the city of Tijuana, Mexico, to adopt a dual transformation process. An analysis of the different digital and sustainable transformation models was carried out, and a self-diagnosis model was designed. Then, a quantitative instrument was applied to a sample of 148 small, medium and large companies in Tijuana between 2022 and mid-2023. The analysis consisted of a descriptive analysis of the data and a correlation analysis. It concludes that the elements that most explain the dual transformation are strategy, culture, organisational and technical capabilities. Likewise, the related factors are definition and communication, alignment, and scope of the objectives within the strategy; change management, knowledge and collaboration in the culture; within the organisation: leadership, processes and organisational structure; and finally in the technical capabilities data management, training and systems integration. The results of this research allowed us to identify and propose strategies to implement the dual transformation and increase the scalability and competitiveness of the adopting companies.

Undoubtedly, the transition to electromobility with several million new, efficient charging points will have consequences for the energy industry, and in particular for network operators of the distribution infrastructure. At the same time, in the coming years the energy landscape will change into a system in which an increase in decentralized systems based on renewable energy sources will take over the leading function. This transformation process will further increase the complexity and overall pressure for change in energy systems over the next decade. In order to be able to ensure the energy supply and the reliable system operation of the grids in the future as well, communicative networking of generators, storage systems, electrical consumers and grid equipment is indispensable. This study aims to investigate the consequences of including electric vehicles in Istanbul's power system using a unit commitment simulation model. The presented considerations analyze how uncertain and managed charging strategies affect the power system in terms of operating costs and renewable resources. The presented simulations indicate that, in economic terms, the use of a managed charging strategy saves 2.3%, reducing the total cost from USD 66.71 million to USD 65.18 million. The recipients of the presented research are both the demand and supply sides of the future energy transformation based on the idea of synergy of electromobility and renewable energy sources within the framework of the smart city idea.

Hidden champions are SMEs with strong global competitiveness in specialized fields but low profile. China's hidden champions show less internationalization compared to their global peers, despite niche market dominance. Consequently, an exploration of the internationalization trajectories and determinants for China's hidden champions is essential. This study utilizes fsQCA to investigate the internationalization strategies of 91 hidden champions, from China, using the "Efficiency-Structure-Environment" analytical framework. Five principal causal pathways for international operations are illustrated, categorized into three main driving models: "Efficiency-Environment,""Efficiency-Structure," and "System Interaction," with the first model being the most dominant. The study further classifies hidden champions by ownership, finding that both state-owned and private enterprises predominantly follow the "Efficiency-Structure" driving model. Additionally, when classified by certification types, all categories are found to align with the "System Integration" model. Notably, the international path for cultivation hidden champions is also well-explained by the "Efficiency Dominance" model. Lastly, the study delineates industry-specific models: general equipment manufacturers employ the "Efficiency-Structure" model, special equipment manufacturers use the "Structure-Environment" model, and the computer industry follows the "System Integration" model. Plain language summary: The international operations of China's hidden champions This research focuses on China's hidden champions, which are small and competitive companies in specific fields that are not widely known. Despite their success in niche markets, these companies have not expanded internationally as their global counterparts. To understand why, the study examines the international strategies of 91 hidden champions using a method called fsQCA. The findings reveal five main paths that lead to internationalization, driven primarily by factors such as efficiency, the business environment, and organizational structure. The study also explores how ownership type and certification play a role in these strategies. Notably, it highlights different approaches for fostering the international growth of hidden champions. The research concludes by identifying industry-specific patterns, showing how companies in general equipment manufacturing, special equipment manufacturing, and the computer industry adopt distinct driving models for their international operations.

In recent years, multimodal approaches to English Teaching (ET) take into account well not the distinct capabilities of text, speech, and visuals and how these modalities may be combined to provide engaging and instructional material for students. The lack of language, articulation issues, lack of enthusiasm, and usage or interference of the mother language are cited as the most significant difficulties students face while learning English. The Classroom Atmosphere (CA) plays a crucial role in facilitating the education system by fostering a sense of trust and fellowship between the instructor and students, increasing students' performance, and reducing disruptive behaviours. Human-Computer Interaction (HCI) aims to enhance the efficiency and satisfaction of users in their interactions with computerized systems integration. This is accomplished by improving the HCI interface given knowledge about the tasks and organizational contexts in which HCI is performed. This paper proposes an HCI-assisted Multimodal English Teaching (HCI-MMET) to promote the classroom atmosphere. Classrooms with a great atmosphere are more conducive to learning. This method helps with high expectations, promoting student participation, making the classroom physically attractive, including parents, and ability to motivate and performance feedback are all ways to establish a healthy classroom atmosphere. The multimodal approach should be used in the classroom for instructing students in a foreign language. Problem-solving and creative thinking are at the basis of HCI, where learners gain the ability to analyze a system, pinpoint problem areas, and provide solutions. Hence the proposed method HCI-MMET gives the outcomes of Classroom interaction and efficiency-83%, Student performance based on a positive atmosphere-75%, Teacher's interest in classroom settings-81%, Student motivation in the multimodal classroom-79%, Development of peer support-86% comparing to the existing methods.

Population Health Management – often abbreviated to PHM – is a relatively new approach for healthcare planning, requiring the application of analytical techniques to linked patient level data. Despite expectations for greater uptake of PHM, there is a deficit of available solutions to help health services embed it into routine use. This paper concerns the development, application and use of an interactive tool which can be linked to a healthcare system's data warehouse and employed to readily perform key PHM tasks such as population segmentation, risk stratification, and deriving various performance metrics and descriptive summaries. Developed through open-source code in a large healthcare system in South West England, and used by others around the country, this paper demonstrates the importance of a scalable, purpose-built solution for improving the uptake of PHM in health services.

There are reasons to affirm that the international scenario of today's world is marked to a large extent by chaos, which is expressed in the development of a set of conflicts, internal and external, in progress or latent. In this sense, the objective of the research was to describe a-priori some philosophical models to understand international relations in today's chaotic world. Methodologically, geopolitical phenomenology and documentary compilation were used as a sufficient condition for the achievement of the set objective. The conclusion is that the integration of systems thinking and chaos theory with hermeneutics, phenomenology, critical analysis of political discourse and the neorealist approach, provides scholars and analysts with a greater ability to anticipate the multifaceted and often unexpected consequences of global interconnectedness.

The global energy system is in transition. It is attempting to reach net‐zero greenhouse gas emissions by 2050. The systemic changes mean that the role of bioenergy will change. The potential of bioenergy to make a flexible contribution to the energy system is key for the achievement of global emission reduction ambitions and the functioning of the low‐carbon energy system and economy. As the volume of sustainably available biomass resources is limited, defining the contributions from bioenergy to a low‐carbon energy system and finding balances – and ideally synergies – between the different possible energy and climate system services that biomass can provide will be very important. The recognized system services include, among others, the flexible operation of bioenergy plants to integrate variable renewable energy sources and to provide negative carbon dioxide (CO2) emissions. Interest in flexible operation of bioenergy value chains, bioenergy with carbon capture and utilization as well as synergies with renewable hydrogen‐based value chains has increased recently. The objective of this paper is to present a holistic definition of flexible bioenergy as a system service based on the work conducted in International Energy Agency (IEA) Bioenergy Technology Collaboration Programme's Task 44 Flexible Bioenergy and System Integration, and to provide some practical examples. The paper also presents the different bioenergy system services and considers their definitions and interactions, as this is important in energy system design. The definition of flexible bioenergy shows that the flexibility provision from bioenergy goes far beyond the traditional definition of providing short‐term flexibility in the power sector. Indicators to demonstrate the value of services as well as further quantitative assessment of synergies and trade‐offs are needed to valorize the different services from bioenergy and create viable business cases.

This research focused on the implementation of state-of-the-art system integration, involving a three-phase 540 KVA bidirectional inverter and a lithium-ion battery energy storage system with a capacity of 1.86 MWh, at the Florida Solar Energy Center (FSEC). The system was firstly put into use at the FSEC for load shifting. The second step was to add photovoltaic (PV) panels for peak shaving. The third step was to take the FSEC completely off-grid. The goal of this research was to provide a case study by implementing a power management algorithm, estimating the PV panel size, and presenting the test results and an analysis. Based on the power management algorithm, load shifting was achieved by using 180 kWh energy storage. To acquire peak shaving and the uniformity of power consumption, an 80 kW PV farm was sufficient. The optimal PV panel size was 500 kW for the off-grid scenario. [ABSTRACT FROM AUTHOR]

The Department of Defense (DoD) employs broad human factors requirements across various applications, resulting in a universal application of the same standards to a multitude of DoD acquisition systems. In unconventional warfare, specifically within missions conducted by US Special Operations Command (USSOCOM), operators face intensified workloads and domain‐specific challenges that current human factors considerations do not adequately address. The objective of this paper aims to introduce a novel framework, the Relational and Technological Capstone (RTC), designed to expand existing Human Systems Integration (HSI) requirements. The objective is to enhance the consideration of human factors in USSOCOM missions by addressing the unique challenges posed by intensified workloads and domain‐specific ontologies. The RTC employs a methodology‐driven approach utilizing both architectural and parametric diagrams. It integrates with Model Based Systems Engineering (MBSE) to improve the design of human‐system interactions, incorporating a Special Operations Task List and Performance Shaping Factors (PSFs) into aggregated parametrics. The results of this paper demonstrate the efficacy of RTC within MBSE, showcasing its value through improved design processes and as a foundation for new programs. The containment tree format aids in developing USSOCOM MBSE and opens possibilities for automation tools. Continual use of RTC contributes to the maturity of MBSE models and diagrams, fostering the evolution of a federation‐of‐models and Program of Record standards. This not only benefits subsequent SOCOM programs and projects but also facilitates cross‐cooperation with other nations in optimizing special operation acquisitions. The ultimate goal is to center the RTC around the operator, ensuring compatibility and optimization across cooperative nations' special operation acquisitions. [ABSTRACT FROM AUTHOR]

The Gateway Program must meet NASA's Agency‐level human rating requirements, which are intended to accommodate human capabilities and limitations while protecting the safety of the crew, and providing to the maximum extent practical, the capability to safely recover the crew from hazardous situations. Human systems integration represents a key human rating component of Moon to Mars systems to support the execution of Artemis missions, including compliance with mandatory standards for Health and Medical, Safety and Mission Assurance, and Engineering. The human system requirements, together with the human systems integration plan, medical operations requirements, and Gateway subsystem specifications, represent the flow‐down of NASA Health and Medical Standards (NASA‐STD‐3001, Volumes 1 and 2) into the Gateway system. This paper discusses how these documents and other human systems integration activities provide full consideration of human capabilities and limitations as part of the total system design trade space, serving as an example on how the human must be effectively integrated as part of the system in order to achieve mission success. At a bigger scale, the paper contributes to the application of systems engineering standards to cutting‐edge space exploration initiatives and to the dialogue on how systems engineering can continue to evolve to meet the needs of such ambitious projects.

Warfighters are often exposed to harsh environmental conditions, and experience high rates of physical and cognitive stress, fatigue, and infections, resulting in the degradation of their health and physical performance. This degradation can have a profound effect on the readiness of military forces. Wearable sensor systems can be used to monitor warfighter physiological and cognitive data, providing insight into their health status during routine military training and deployed operations; however, to enable a real‐time, tactical health and performance monitoring capability, wearable sensor systems must integrate into existing tactical military information networks without compromising network function. We extended our existing Wearables Model‐Based System Engineering – System Architecture (MBSE‐SA) to include a bandwidth simulation to analyze the effects wearable sensor systems have on overall network function specifically for military use cases. Our Wearables MBSE‐SA enabled us to model many notional and existing architectures, which represent the wide range of wearable sensor devices, communication protocols, end user devices, and tactical network nodes typically present in operational environments. By taking advantage of the existing Wearables MBSE‐SA framework and architectures, the resulting bandwidth simulation rapidly assessed several existing military network architectures for wearable sensor system integration and identified where network changes were required. Validating the flexibility of the Wearables MBSE‐SA to incorporate new analyses was critical for the military's ability to explore wearable sensor system trades and evaluate architectures in the quickly changing wearable systems technology domain.

District energy management systems (DEMS) offer the capability to harness the energy potential of districts. Currently, there is a lack of research describing the necessary underlying information systems. An overview of lessons learned is presented from a series of workshops with experts from industry, research, and further roles, predominately from Germany. Seven workshops discussing challenges within digitalization, data requirements, district energy system planning, common elements in district energy systems are conducted, ensuring long‐term operation and transferability, and validation of prior findings. Based on these discussions, insights into topics such as the key data and its requirements, typical distinctions in DEMS, their infrastructure, considerations in the information modeling, as well as challenges in data availability, are offered. These findings are mapped to a data value pipeline, illustrating key resources and tools needed to plan and operate DEMS. As demonstrated in this article, the requirements for DEMS highlight their complexity. Distinct categorizations, such as the ownership or heterogeneity in building and technologies, form the landscape of DEMS. The need for standardized, interoperable systems is often a contrast to the uniqueness of individual systems and their needs. Further adoption of the described concepts necessitates sustainable business models. [ABSTRACT FROM AUTHOR]

The triboelectric nanogenerator (TENG) holds significant potential for applications in energy harvesting and environment monitoring. However, a notable challenge lies in developing a combined system capable of efficiently harvesting energy and providing real‐time self‐powered sensing. Here, a combined wind energy harvesting and speed sensing (EHSS) system is constructed based on a noncontact electricity‐induced constant‐voltage TENG (EICV‐TENG) that achieves constant output by coupling two different phases and incorporates a parasitic sensing module in a single phase. Through the optimization of system integration, the EICV‐TENG achieves a current density of 28.7 mA m−2 and an average power density of 0.26 W m−2 Hz−1. With an optimal power management, the energy output efficiency of the EICV‐TENG reaches up to 96%. And EICV‐TENG can stably power 32 commercial hygrothermographs connected in parallel with the PMC at a wind speed of 7 m s−1. In addition, the EHSS system demonstrates excellent real‐time sensing performance based on the correlation between the peak number of pulse output in a single phase and wind speeds. This work contributes to the advancement of TENG technology for a combined energy harvesting and self‐powered sensing system in the context of the Internet of Things (IoTs). [ABSTRACT FROM AUTHOR]
