Recent advances in highly integrated energy conversion and storage system

Abstract: The vigorous development in the field of energy conversion and storage devices directly contributes to the full utilization and convenient use of clean energy. However, some drawbacks of independent energy conversion and storage devices, including unstable, insufficient energy output and dependence on external power supply, are difficult to overcome by self‐optimization, thus, hindering their further development and direct application. Coincidentally, the combination of above two devices can solve these problems, which conforms to their intrinsic needs for development. At the same time, the pursuit of portability and miniaturization also promotes the development of the power system toward a highly integrated direction. Therefore, we introduce several integration modes of energy conversion and storage systems, with emphasis on all‐in‐one power system, possessing the highest integration in this review. From the aspect of device configuration, working mechanisms and their performances, the all‐in‐one power systems based on different energy sources (e.g., mechanical, solar, thermal, and chemical energy) are discussed and analyzed. Finally, the design strategies are summarized and the potential development directions in the future are proposed. This review aims to provide a comprehensive overview of highly integrated energy conversion and storage system, and seeks to point out the opportunities and orientations of future research in this field.

Deep Conviction Systems for Biomedical Applications Using Intuiting Procedures With Cross Point Approach

Abstract: The production, testing, and processing of signals without any interpretation is a crucial task with time scale periods in today's biological applications. As a result, the proposed work attempts to use a deep learning model to handle difficulties that arise during the processing stage of biomedical information. Deep Conviction Systems (DCS) are employed at the integration step for this procedure, which uses classification processes with a large number of characteristics. In addition, a novel system model for analyzing the behavior of biomedical signals has been developed, complete with an output tracking mechanism that delivers transceiver results in a low-power implementation approach. Because low-power transceivers are integrated, the cost of implementation for designated output units will be decreased. To prove the effectiveness of DCS feasibility, convergence and robustness characteristics are observed by incorporating an interface system that is processed with a deep learning toolbox. They compared test results using DCS to prove that all experimental scenarios prove to be much more effective for about 79 percent for variations with time periods.

Overview of the SmartX Wing Technology Integrator

Abstract: This article describes the challenges of integrating smart sensing, actuation, and control concepts into an over-sensed and over-actuated technology integrator. This technology integrator has more control inputs than the expected responses or outputs (over-actuated), and its every state is measured using more than one sensor system (over-sensed). The hardware integration platform is chosen to be a wind tunnel model of a low-speed aircraft wing such that it can be tested in a large university-level wind tunnel. This hardware technology integrator is designed for multiple objectives. The nature of these objectives is aerodynamic, structural, and aeroelastic, or, more specifically; drag reduction, static and dynamics loads control, aeroelastic stability control, and lift control. Enabling technologies, such as morphing, piezoelectric actuation and sensing, and fibre-optic sensing are selected to fulfil the mentioned objectives. The technology integration challenges are morphing, actuation integration, sensor integration, software and data integration, and control system integration. The built demonstrator shows the intended level of technology integration.

A framework of system integration and integration value analysis: Concept and case studies

Abstract: In modern society, system integration that enables multiple subsystems to function as one is emerging in various fields like industry, commerce, and infrastructure. Although it has been proved that integration value could be tapped to the maximum with controllable cost by optimising the integration schemes in certain fields, there is still a lack of a general method for modelling and analysing the process of system integration. To address this need, this paper proposes an analysis framework of system integration. The concepts of integration object, integration strategy, integration time, integration cost and integration value are introduced to describe the integration process. Further, three optimisation models of the local optimisation (OPT1), phase optimisation (OPT2) and integration optimisation (OPT3) are constructed. The proposed framework can also supervise and compare the performance of intermediate processes of different integration schemes. Two case studies in the commerce and energy fields are analysed to illustrate the function of the proposed framework.

Enhancing Monitoring and Control of an HVAC System through IoT

Abstract: Throughout time, European policies on climate and energy change have generated several transformations in the building sector. In this endeavour, digital technologies have played an essential role in energy efficiency through process optimisation. However, data integration and exchange between different solutions is still challenging to achieve. With the advancement of Internet of Things (IoT) based solutions, one of the latest innovations, new opportunities are envisioned. IoT solutions have been implemented in smart grids, intelligent buildings, smart cities, and other sectors in recent years. Following the guidelines of ISA/ANSI 95-Enterprise-Control System Integration, the edge computing apps and cloud platform are needed to solve data bottlenecks, data ingestion, data integration aspects, bringing at the same time new knowledge related to user comfort, energy management and accessibility. This research focuses on a case study that shows how the thermal comfort of a building can be controlled and improved through an IoT vertically integrated solution. The deployed solution opens new possibilities for cross-functional integration and data aggregation, an essential step towards energy efficiency.

Integration of Train Control and Online Rescheduling for High-Speed Railways in Case of Emergencies

Abstract: The high-speed train control system is essential to the safety and efficiency of train operation. With the rapid increase of high-speed railway (HSR) operating mileage and development of information technology, the disposal flow and methods in emergency response are still based on dispatchers and drivers’ experience within the “layered” architecture of current system. There is a certain gap between current processing methods and effective resolution, which may even cause the spread of delay along with the railway networks. Therefore, we propose an integration system of operation control and online rescheduling to improve the recovery ability of HSR carrying capacity. We first describe the framework, information flow, and disposal process of the current system and analyze the shortcomings in handling emergencies. Then, the basic concept, system structure, and framework of the integration system are introduced. Finally, taking temporary speed restriction caused by strong wind as an example, we also analyze the principle of why and how the integration system can promote the recovery ability of HSR carrying capacity.

Abstract: SOXS (SOn of X-Shooter) is a medium resolution (~4500) wide-band (0.35 - 2.0 µm) spectrograph which passed the Final Design Review in 2018. The instrument is in the final integration phase and it is mainly composed of five different optomechanical subsystems and four other mechanical subsystems (Interface flange, Platform, cable corotator, and cooling system). In this paper, a brief overview of all the subsystems and tools is presented here together with the acceptance results of the various mechanical elements, the experiments performed to validate the functionality of the subsystems, and the mechanical integration procedure.

A Graphical Method for Combined Heat Pump and Indirect Heat Recovery Integration

Abstract: Industrial sectors are improving their energy efficiency and increasing their share of renewables for heating and cooling demands by using lower emission technologies. One specific approach to help achieve these targets is the integration of heat pumps (HPs) in industrial processes. However, due to the temporal variation of the heating and cooling requirements in non-continuous processes, the integration of HP is challenging. In this paper, a structured method for the design of HP integration is proposed. The method implements an engineer-centred workflow that extends the concept of the Indirect Source Sink Profile (ISSP) to HP integration. For this purpose, an adapted Grand Composite Curve is derived from the ISSP. This ensures correct HP integration across the pinch while maintaining the temperature lift of the HP small. The proposed workflow is applied to a demonstration case study and a case study from industry. In both cases, the resulting system with integrated HP enables the elimination of hot utility demand and significantly reduces cold utility demands. The static paybacks of the proposed solutions are in the range of 4.5 to 5 year.

Systems integration implications of component reuse

Abstract: Component and subsystem reuse has been an important tool in controlling the cost and schedule requirements of developing new aerospace systems. Although the mere utilization of component reuse cannot be shown to influence system integration success significantly, previous research has shown that interactions between reuse and other integration principles do significantly influence integration success. The research described in this paper leverages historical system data to characterize these interactions and assess the influence of these interactions on integration success. This research identifies four characterizations of interactions between reuse and the other principles that significantly influence system integration success when component reuse is included in the system design.

Integration and Deployment of Cloud-Based Assistance System in Pharaon Large Scale Pilots—Experiences and Lessons Learned

Abstract: The EU project Pharaon aims to support older European adults by integrating digital services, tools, interoperable open platforms, and devices. One of the objectives is to validate the integrated solutions in large-scale pilots. The integration of mature solutions and existing systems is one of the preconditions for the successful realization of the different aims of the pilots. One such solution is an intelligent, privacy-aware home-care assistance system, SmartHabits. After briefly introducing the Pharaon and SmartHabits, the authors propose different Pharaon models in the Ambient/Active Assisted Living (AAL) domain, namely the Pharaon conceptual model, Pharaon reference logical architecture view, AAL ecosystem model, meta AAL ecosystem model, and Pharaon ecosystem and governance models. Building on the proposed models, the authors provide details of the holistic integration and deployment process of the SmartHabits system into the Pharaon ecosystem. Both technical and supporting integration challenges and activities are discussed. Technical activities, including syntactic and semantic integration and securing the transfer of the Pharaon sensitive data, are among the priorities. Supporting activities include achieving legal and regulatory compliance, device procurement, and use-case co-designing in COVID-19 conditions.

Quantitative validation of complex systems integration principles

Abstract: The integration of complex systems is an important aspect of systems engineering. Previous research derived six integration principles and qualitatively validated four of them using a data set of 14 systems. Of the two non‐validated principles, one was determined to be confounded with two of the four validated principles and is hence not considered in this research. This paper describes the quantitative validation of the resulting five integration principles based on an expanded data set of 52 systems. This expanded data set is analyzed statistically, and the interactions between integration principles are also evaluated. This research quantitatively validates four of the five integration principles and identifies three principle interactions that are significantly related to integration success, solidifying validity of the principles, and identifying three cases where the principles interact that must be further explored.

Systems integration in infrastructure projects: seven lessons from Crossrail

Abstract: A systems integration model for the delivery of complex infrastructure projects is proposed. From the Crossrail case, the authors draw seven lessons for clients to: (1) manage programme delivery as an integration activity; (2) actively manage systems integration; (3) ensure authority to make decisions; (4) maintain configuration control; (5) plan for a lengthy testing and commissioning phase; (6) appreciate supply chain products that may be part of unaligned global research and development programmes; and (7) do final integration only when there is something to integrate. Central to the argument is the idea that on such complex projects, the client cannot outsource systems integration and thus needs to recognise they retain accountability, though roles and responsibilities can be assigned to the delivery partner, supply chain, chief engineer and/or contracted systems integration firm. A key question for the client at the outset is how to distribute interface management and systems integration responsibilities while retaining accountability and oversight. Rather than managing through contracts, budgets and schedules, the authors suggest a changed approach with priority given to managing integration, and contracts, budgets and schedules that support and incentivise this.

A 1kV, 480V Power Electronics Hub for DER Integration in Commercial Buildings

Abstract: Power electronic (PE) systems are increasingly being integrated into distribution and sub-distribution networks in support of distributed energy resource integration (DERs), electric vehicle (EV) charging (particularly in the case of fast charging infrastructure), and improvement in power quality for high performance computing and/or servers farms. This provides an opportunity to research and develop integrated PE systems that can function as single systems thereby bringing additional functionality and benefits to the overall system. The goal of this paper is to demonstrate foundational technologies and capabilities for a multiport power electronics energy hub that can intelligently coordinate and control integrated sources and loads. The focus for this digest is on a commercial building use case which is demonstrated in hardware.

Systemic Integrated Unmanned Aerial System

Abstract: Systemic integrated Unmanned Aerial System (UAS), is the process of gathering the subsystems into one fulfilled system. This integration is done in order to improve the system performance, reducing operational costs, and improving the time response of the system. Normally, such systems are integrated using different techniques such as communication processes, and computer networking. In this paper, a new integrated system is implemented by linking functionally computing systems and software applications together in one powerful system.

Integration process simulator: A tool for performance evaluation of task scheduling of integration processes

Abstract: ABSTRACT Due to large volumes of data from Cloud Computing and from the Internet of Things, the companies’ software ecosystem requires an efficient integration of applications and services. Performance improvement from integration platforms’ runtime systems is directly related to task scheduling strategies from integration processes. It is still a challenge to find the proper heuristic for a given integration process subject to high inbound data rates. This article proposes a simulation tool for the field of Enterprise Application Integration, which implements different scheduling heuristics and allows the extraction of performance metrics. Three task scheduling heuristics were simulated during the integration process, and the results were evaluated through statistical tests.

Nurse practitioner integration: Conceptual development to enhance application in policy and research

Abstract: Nurse practitioners (NPs) have been introduced across the world to improve care quality and solve provider shortages. Realizing these benefits relies on their successful integration into health care systems. Although NP integration has been discussed extensively, the concept is defined inconsistently. Literature, therefore, cannot be synthesized to create policy recommendations for management and policymakers to plan for and advance NP integration.To describe and define NP integration and enhance its applicability in research and policy.A modified Walker and Avant concept analysis was used to develop a conceptual model of NP integration. Data were extracted and synthesized from 78 sources referencing the concept.Nurse practitioner integration was operationally defined as the multilevel process of incorporating NPs into the health care system so that NPs can practice to their full scope, education, and training and contribute to patient, system, and population needs. The attributes of NP integration are: 1) achievable goal; 2) process; 3) introduction of the role; 4) incorporation into organizational care models; 5) challenging traditional ideologies; 6) ability to function; 7) provide high-quality care; and 8) improve outcomes, sustainability, and health system transformation. Seventeen facilitators/barriers affecting NP integration were identified. Three health care system levels at which integration occurs were identified- macro , meso , and micro .Findings will inform managers, policymakers, and stakeholders about NP integration to aid in planning and policy development. Results can be used to inform research on barriers and facilitators to NP integration.

An integration engineering framework for machine learning in healthcare

Abstract: Background and Objectives Machine Learning offers opportunities to improve patient outcomes, team performance, and reduce healthcare costs. Yet only a small fraction of all Machine Learning models for health care have been successfully integrated into the clinical space. There are no current guidelines for clinical model integration, leading to waste, unnecessary costs, patient harm, and decreases in efficiency when improperly implemented. Systems engineering is widely used in industry to achieve an integrated system of systems through an interprofessional collaborative approach to system design, development, and integration. We propose a framework based on systems engineering to guide the development and integration of Machine Learning models in healthcare. Methods Applied systems engineering, software engineering and health care Machine Learning software development practices were reviewed and critically appraised to establish an understanding of limitations and challenges within these domains. Principles of systems engineering were used to develop solutions to address the identified problems. The framework was then harmonized with the Machine Learning software development process to create a systems engineering-based Machine Learning software development approach in the healthcare domain. Results We present an integration framework for healthcare Artificial Intelligence that considers the entirety of this system of systems. Our proposed framework utilizes a combined software and integration engineering approach and consists of four phases: (1) Inception, (2) Preparation, (3) Development, and (4) Integration. During each phase, we present specific elements for consideration in each of the three domains of integration: The Human, The Technical System, and The Environment. There are also elements that are considered in the interactions between these domains. Conclusion Clinical models are technical systems that need to be integrated into the existing system of systems in health care. A systems engineering approach to integration ensures appropriate elements are considered at each stage of model design to facilitate model integration. Our proposed framework is based on principles of systems engineering and can serve as a guide for model development, increasing the likelihood of successful Machine Learning translation and integration.

Towards Easy Robot System Integration: Challenges and Future Directions

Abstract: The amount of robots in industry is increasing, pushing the need for easier configuration and integration of robots. The cost of robot integration is often larger than the cost of the robots themselves. With the increasing complexity of robotic systems and the tasks they perform, the future of reducing the expenses of robot system integration is significant. In this position paper, we report on some of the main challenges in robot system configuration, and give an overview of the current state-of-the-art of robot system configuration. We briefly look into the configuration of personal computers (PCs) and study how the robot system configuration can be improved inspired by the standards used in the PC area. We conclude with concrete proposals as to what can be done in the future, to make the process of robot system configuration and integration easier and cheaper.

Wafer‐Scale Integration

Abstract: The key challenges of on-chip integration, including limited scalability, high cost, difficulty to maintain profitable yield, and increased thermal management complexity, suggest that additional avenues for scaling should be explored. Wafer-scale integration is the extension of the system-on-chip approach to ultralarge systems. A comprehensive review of this transition from the standpoint of packaging, thermal management, and system integration is presented in this article. The benefits and challenges of wafer-scale integration are discussed. Silicon interconnect fabric, a promising platform for high-performance heterogeneous wafer-scale integration, is introduced.

Hardware and software implementation of POCT1-A for integration of point of care testing in research

Abstract: Point of care testing (POCT) is increasingly utilized in clinical medicine. Small, portable testing devices can now deliver reliable and accurate diagnostic results during a patient encounter. With these increases in POCT, the issue of data and results management quickly emerges. Results need to be cataloged accurately and efficiently while the providers/support staff are simultaneously managing patient encounters. The integration of electronic medical records (EMR) as data repositories requires that point of care testing data imports automatically into the EMR. POCT1-A was developed as a standard communication language for POCT device manufacturers to streamline automatic data import integration. While all modern POCT devices are built with this connectivity, the systems that provide the integration layer are often proprietary and require a fee for service. In the research environment, there is not enough throughput to justify the practical investment in these data management architectures. Moreover, researcher needs are different and unique compared to data management systems for clinicians. To meet this need, we developed a novel hardware and software connectivity solution using commercially available components to automate data management from a point-of-care blood biochemical analyzer during a critical care study in the preclinical research environment.

Inter-Organizational System Integration

Abstract: Manufacturing firms have increasingly relied on inter-organizational systems (IOS) to facilitate inter-firm transactions and integration with suppliers. However, they frequently face various impediments, such as adversarial behaviours and misalignments, when trying to integrate with IOS (i.e., IOS integration or IT/IS integration). Based on the perspectives of mutual adaptation of technology and organization and socio-technical systems, this study develops two compromise constructs critical for IOS integration: inter-firm process compromise and technology compromise. These two compromise constructs, treated as neutral alignment, are proposed to affect the achievement of higher IOS integration. Based on 146 matched-pair samples, the findings demonstrate the importance of technology and inter-firm process compromises in achieving greater IOS integration, which, in turn, enables higher inter-firm dependence and operational performance. This research provides theoretical and practical implications that contribute to our understanding of the role of compromise in facilitating IOS integration. The implications should serve as an important basis for future research in examining IOS integration.
