<strong>Background and Aim of Study: </strong>The increasing use of information technologies in healthcare has enhanced communication between its stakeholders and has also reduced health cost. As a result, data interoperability has become a priority which has increased the need to assess whether health information systems (HIS) used are interoperable enough to support this call. The aim of the study: to assess the data interoperability of the HIS used in the South African public healthcare.<strong>Material and Methods:</strong> Based on the conceptual model with the constructs of core, policy, societal, engagement as well as acceptance and use readiness and parameters of functional, syntactic and semantic interoperability, a measuring instrument in the form of closed-ended questionnaire was designed. Statistical data was collected from Information Technology personnel in three district hospitals of Gauteng Province in South Africa.<strong>Results:</strong> Hypotheses 1, 3 5, 6a and 6c predicted the influence of core readiness, societal readiness, use readiness functional interoperability and semantic interoperability on HIS data interoperability readiness respectively and were all accepted. Hypothesis 2, 4 6b predicted the influence of policy readiness, engagement readiness and syntactic interoperability on HIS data interoperability readiness and were all rejected.<strong>Conclusions:</strong> The developed model can be used to enhance research on data interoperability that is a major challenge in the use of information technology in healthcare. The sharing of information among different levels of medical personnel is essential for healthcare quality, efficiency, and safety of care provided to a patient. To enable this, systems should be able to connect and exchange information with each other without limitation. Such also enables better workflows, reduce ambiguity, and allows data transfer among systems and healthcare stakeholders.

Global Navigation Satellite System (GNSS) interoperability could make use of the information from different navigation satellite systems. To estimate GNSS interoperability at the system level, an innovative assessment algorithm was presented in this paper. First of all, three assessment parameters, namely, Dilution Of Precision (DOP), Navigation Satellite System Precision (NSSP) and Navigation Satellite System Integrity (NSSI) were introduced. Secondly, availability and continuity of the assessment parameters were adopted to quantify the GNSS performance. A further step was then taken to focus on the assessment rule for GNSS performance by employing the weighted sum of availability and continuity. Simulation results demonstrate that GNSS performance could be improved significantly by interoperability.

Interoperability is a challenge for the realisation of smart grids. In this work, we apply the methodology for interoperability testing and the design of experiments developed at the Smart Grids Interoperability Laboratory of the Joint Research Centre of the European Commission on a simple use case. The methodology is based on the Smart Grid Architecture Model (SGAM) of CEN/CENELEC/ETSI and includes the concept of Basic Application Profiles (BAP) and Basic Application Interoperability Profiles (BAIOP). The relevant elements of the methodology are the design of experiments and the sensitivity/uncertainty analysis, which can reveal the limits of a system under test and give valuable feedback about the critical conditions which do not guarantee interoperability. The design and analysis of experiments employed in the Joint Research Centre (JRC) methodology supply information about the crucial parameters that either lead to an acceptable system performance or to a failure of interoperability. The use case on which the methodology is applied describes the interaction between a data concentrator and one or more smart meters. Experimental results are presented that show the applicability of the methodology and the design of experiments in practice. The system is tested under different conditions by varying two parameters: the rate at which meter data are requested by the data concentrator and the number of smart meters connected to the data concentrator. With this use case example the JRC methodology is illustrated at work, and its effectiveness for testing interoperability of a system under stress conditions is highlighted.

Full textAbstract:
Interoperability testing is widely recognized as a key to achieve seamless interoperability of smart grid applications, given the complex nature of modern power systems. In this work, the interoperability testing methodology proposed by the European Commission Joint Research Centre is applied to a specific use case in the context of smart grids. The selected use case examines a flexibility activation mechanism in a power grid system and includes DSO SCADA, Remote Terminal Unit and flexibility source, interacting to support a voltage regulation service. The adopted test bed consists of a real-time power grid simulator, a communication network emulator and use case actors’ models in a hardware-in-the-loop setup. The breakdown of the interoperability testing problem is accomplished by mapping the use case to the SGAM layers, specifying the Basic Application Profiles together with the Basic Application Interoperability Profiles (BAIOPs) and defining the design of experiments to carry out during the laboratory testing. Furthermore, the concepts of inter- and intra-BAIOP testing are formalized to reflect complementary interests of smart grid stakeholders. Experimental results prove the applicability of the methodology for testing the interoperability of large-scale and complex smart grid systems and reveal interesting features and possible pitfalls which should be considered when investigating the parameters responsible for the disruption of a system interoperability.

Full textAbstract:
The interoperability of wireless charging for electric vehicles refers to the radio energy transmission that meets the performance and function requirements of different manufacturers and different models of electric vehicles on the premise of meeting the relevant requirements. If it fails to meet the requirements, the wireless charging system of electric vehicles has difficulty to realize interconnection and low charging efficiency, Therefore, how to evaluate the interoperability is a key issue in the promotion of electric vehicle wireless charging. In this paper, an interoperability evaluation method based on two parameters is proposed. The interoperability impedance plane is constructed by the system detuning coefficient A. The comprehensive evaluation of different compensation networks and coupling coils is realized; the power characteristic impedance ε is obtained by analyzing and calculating the relationship between the transmission power of the system while the system impedance, and the transmission power evaluation of the wireless power transmission system is realized. At the same time, according to simulation and experiment, it was verified that A meets the interoperability requirements when A is in the range of (−0.62, 0.62) in the aligned position and (−0.75, 0.75) in the offset position. When the input voltage is 200 V, when ε satisfies 0.1925 ≥ ε > 0.0925, the system WPT2 power level transmission interoperability requirements are met. The method in this paper can guide the interoperability evaluation of electric vehicle wireless charging.

Full textAbstract:
In recent years, Internet-of-Things (IoT)-based applications have been used in various domains such as health, industry and agriculture. Considerable amounts of data in diverse formats are collected from wireless sensor networks (WSNs) integrated into IoT devices. Semantic interoperability of data gathered from IoT devices is generally being carried out using existing sensor ontologies. However, crop-specific trait ontologies—which include site-specific parameters concerning hazelnut as a particular agricultural product—can be used to make links between domain-specific variables and sensor measurement values as well. This research seeks to address how to use crop-specific trait ontologies for linking site-specific parameters to sensor measurement values. A data-integration approach for semantic and syntactic interoperability is proposed to achieve this objective. An open-data platform is developed and its usability is evaluated to justify the viability of the proposed approach. Furthermore, this research shows how to use web services and APIs to carry out the syntactic interoperability of sensor data in agriculture domain.

Full textAbstract:
ISO standards for intermodal shipping containers have dramatically improved efficiency within the shipping industry worldwide. The translation/localization industry needs an analogous standard for translation projects and tasks. There are a variety of proprietary translation formats that allow materials relevant to a translation project (the source text, various resources such as translation memory files, etc.) to be put into one or more packages and sent to a translator. The translator can then use the same format to return the requested information, such as the translation. The objective of the Linport Project is to define an open, nonproprietary format for describing translation projects and creating translation packages, plus transmission and remote-access mechanisms needed to support implementation of the format. Linport stands for Language Interoperability Portfolio, where a portfolio is the description of a translation/localization project. An important feature of the Linport Project is structured translation specifications compatible with the system of parameters in recently published ISO/TS 11669.

For the past few years, technology has been steadily rising and leading to rapid change in the development process. Information & Communication Technology (ICT) approaches have been moving toward new development trends with a huge elevation of comprehension. Service providers are always seeking customer satisfaction and due to multiple essentials, clients prefer to migrate from one application to another. Newer software applications are being launched, but they are constricted within a defined scope and cannot perform functions of interoperable components. Therefore,the aim of this study is to facilitate clients with multiple services over a single platform and gain knowledge about cloud computing, service computing techniques to enable flexibility and interoperability between applications. This work proposes an STA-Vision19 cloud platform and Service Integration Bridge (SIB) as solutions. To validate methods,abasic prototype for the proposedframework STA-Vision19 andtwo applications E-Learning and Blogging System were implemented. In results, software evaluation parameters, and testing results are discussed, which indicates that the proposed system can collaborate two or more applications and it is beneficial to use as compared to an isolated system.

Owing to the requirements of the AM system integration and standardization for an AM part structure, the AM features and parameters need to extend their related data entities for better information exchange and sharing based on STEP-NC Part 17 for additive manufacturing. In this paper, we propose an architecture to transfer the manufacturing layer feature and process parameter information among the CAD/CAPP/CAM systems. We classify the AM layer features into four: general geometry feature, foam structure feature, honeycomb structure feature, and lattice structure feature. These features include detailed parameters and a physical performance that represent specific feature data with related entity definitions and relation descriptions. The process information specifies the optimal process parameters that provide the possibility for optimization data interoperability in various application systems. Based on the concepts of the manufacturing layer feature and process parameters in AM, we simultaneously present the specific STEP/STEP-NC-compliant data model to represent the AM layer feature and process parameter information exchange. Absolutely, we also give the conformance analysis and implementation for each application object and the data entities in the interoperability process.

Abstract Mobile and stationary sensors currently used to measure various environmental parameters, functioning independently or as part of monitoring networks and measurement stations, provide vast amounts of data on the state and quality of the environment on the Earth. If the data is to be used effectively, they must be exchanged and shared among IT systems. Systems which offer services of searching, exchange, sharing, visualisation and analysis of dispersed and varied data resources on the widely understood environment are, for example, spatial data infrastructures. The article presents an overview of IT technologies and standards which offer interoperability in spatial data infrastructures. It first defines interoperability and then describes the most important issues connected with spatial data infrastructures on the example of INSPIRE. An example standard which facilitates interoperability in INSPIRE is the SensorML language, a component of Sensor Web Enablement (SWE). Its practical application is proposed – for description of processes of air monitoring in a spatial data infrastructure that is an element of the Polish national environmental monitoring plan.

Electromagnetic metamaterial is an artificial material that is made up of different types of structural designs on dielectric substrates. In this paper a broad and elite investigation is being carried out by designing and simulating a metamaterial cell comprising a square split ring resonator with a copper wire strip etched on the ground plane to discover its some unusual parameters such as double negativity of cell which are naturally not found in other materials of nature. A course of action of these unit cells in a grouping shapes metamaterial. These metamaterial cells show exceptionally great applications in the design of microstrip patch antennas by improving their characteristics such as bandwidth, return loss, and gain. The proposed microstrip line feed patch antenna is designed at a 3.5 GHz resonance frequency useful for various worldwide interoperability for microwave access (WiMAX) applications. The ground plane of a substrate of a patch antenna is loaded with a square split-ring resonator, the proposed antenna is fabricated to obtain experimental parameters. A conventional and proposed patch antenna is simulated, fabricated tested analysed, and reported for performance comparison of its parameters.

The goal of developing therapies and dosage regimes for characterized subgroups of the general population can be facilitated by the use of simulation models able to incorporate information about inter-individual variability in drug disposition (pharmacokinetics), toxicity and response effect (pharmacodynamics). Such observed variability can have multiple causes at various scales, ranging from gross anatomical differences to differences in genome sequence. Relevant data for many of these aspects, particularly related to molecular assays (known as ‘-omics’), are available in online resources, but identification and assignment to appropriate model variables and parameters is a significant bottleneck in the model development process. Through its efforts to standardize annotation with consequent increase in data usability, the human physiome project has a vital role in improving productivity in model development and, thus, the development of personalized therapy regimes. Here, we review the current status of personalized medicine in clinical practice, outline some of the challenges that must be overcome in order to expand its applicability, and discuss the relevance of personalized medicine to the more widespread challenges being faced in drug discovery and development. We then review some of (i) the key data resources available for use in model development and (ii) the potential areas where advances made within the physiome modelling community could contribute to physiologically based pharmacokinetic and physiologically based pharmacokinetic/pharmacodynamic modelling in support of personalized drug development. We conclude by proposing a roadmap to further guide the physiome community in its on-going efforts to improve data usability, and integration with modelling efforts in the support of personalized medicine development.

Building Information Modelling (BIM) has become an emerging digital technology in the architecture, engineering and construction (AEC) industry. There is a growing demand on applying BIM for sustainable design including the building energy simulation (BES). Lack of sufficient interoperability has caused barriers to utilize the information from BIM for BES. In this study, the interoperability between BIM and four different BES tools (i.e., Ecotect, EQUEST, Design Builder and IES-VE) was explored by using a case study of a residential building in the design stage. The misrepresented information from BIM to multiple BES tools were identified based on six different categories of building information parameters. The research proposed an approach of creating gbXML file with an improved integrity of information in BIM. Overall, this study would lead to further work in developing platforms for improving the information transformation from BIM to BES.

AbstractThe new medical device communication protocol known as IEEE 11073 SDC is well-suited for the integration of (surgical) point-of-care devices, so are the established Health Level Seven (HL7) V2 and Digital Imaging and Communications in Medicine (DICOM) standards for the communication of systems in the clinical IT infrastructure (CITI). An integrated operating room (OR) and other integrated clinical environments, however, need interoperability between both domains to fully unfold their potential for improving the quality of care as well as clinical workflows. This work thus presents concepts for the propagation of clinical and administrative data to medical devices, physiologic measurements and device parameters to clinical IT systems, as well as image and multimedia content in both directions. Prototypical implementations of the derived components have proven to integrate well with systems of networked medical devices and with the CITI, effectively connecting these heterogeneous domains. Our qualitative evaluation indicates that the interoperability concepts are suitable to be integrated into clinical workflows and are expected to benefit patients and clinicians alike. The upcoming HL7 Fast Healthcare Interoperability Resources (FHIR) communication standard will likely change the domain of clinical IT significantly. A straightforward mapping to its resource model thus ensures the tenability of these concepts despite a foreseeable change in demand and requirements.

Full textAbstract:
Integrated navigation using multiple Global Navigation Satellite Systems (GNSS) is beneficial to increase the number of observable satellites, alleviate the effects of systematic errors and improve the accuracy of positioning, navigation and timing (PNT). When multiple constellations and multiple frequency measurements are employed, the functional and stochastic models as well as the estimation principle for PNT may be different. Therefore, the commonly used definition of “dilution of precision (DOP)” based on the least squares (LS) estimation and unified functional and stochastic models will be not applicable anymore. In this paper, three types of generalised DOPs are defined. The first type of generalised DOP is based on the error influence function (IF) of pseudo-ranges that reflects the geometry strength of the measurements, error magnitude and the estimation risk criteria. When the least squares estimation is used, the first type of generalised DOP is identical to the one commonly used. In order to define the first type of generalised DOP, an IF of signal–in-space (SIS) errors on the parameter estimates of PNT is derived. The second type of generalised DOP is defined based on the functional model with additional systematic parameters induced by the compatibility and interoperability problems among different GNSS systems. The third type of generalised DOP is defined based on Bayesian estimation in which the a priori information of the model parameters is taken into account. This is suitable for evaluating the precision of kinematic positioning or navigation. Different types of generalised DOPs are suitable for different PNT scenarios and an example for the calculation of these DOPs for multi-GNSS systems including GPS, GLONASS, Compass and Galileo is given. New observation equations of Compass and GLONASS that may contain additional parameters for interoperability are specifically investigated. It shows that if the interoperability of multi-GNSS is not fulfilled, the increased number of satellites will not significantly reduce the generalised DOP value. Furthermore, the outlying measurements will not change the original DOP, but will change the first type of generalised DOP which includes a robust error IF. A priori information of the model parameters will also reduce the DOP.

Although a large number of e-learning systems for individual learning support exist today, many of them still deal with pedagogical issues in an isolated way. In contrast, intertwining interactive system features with educational concepts allows pedagogical designs that may be considered according to their educational rationale. However, pedagogical approaches also do not provide requirements for technologies; they rather consider tools and features as predefined design parameters. Taking an interoperability point of view allows focus on the interaction between the pedagogical and the technological systems. By interpreting technology and didactic approaches as systems and ensuring their interoperability, educators are able to adapt learning experiences and technological features in a way that the overall learning system becomes personalized. A key element of the described work is an architecture that captures the design elements from both progressive education focusing on individual learning support, and the enabling web-based e-learning technologies.

The overall purpose of this research is to consider the considerations and design of many blockchain structures in digital international environments for smooth cross-chain operations. This work investigates the problems and possibilities involving the enhancement of interoperability of blockchains together with various sectors like healthcare, decentralized finance, and individual energy management. In the context of the same, the current study shall employ four different blockchain algorithms where the same interoperability protocols shall be measured based on parameters like efficiency, security, and scalability across the nodes. Outcomes reveal that the proposed framework improved transaction velocity by 35%, cut transaction costs by 20% ad heightened data security by 40% as reviewed to centralized structural styles. This study also demonstrates that cross-chain solutions are effective for scalability as decentralized applications run across different chains. The research shows that despite the fact that major advancements have been observed regarding cross-chain communication, other issues, including consensus synchronization and network protection remain issues that require solutions. Anatomy of these outcomes raises the awareness about the need to adhere to standards, and to build safe approaches to consensus needed to increase the share of holistic blockchain platforms. Cultivating practical awareness of interoperability in blockchain is as important as extending the real-life application of blockchain in a global environment by increasing data exchange, reducing operating expenses, ensuring safe and transparent transactions, and improving data exchange.

Full textAbstract:
Building owners are working on converting their legacy documentation 2D floor plans into digital 3D representations, but the manual process is labor-intensive and time-consuming. In this paper, deep learning is leveraged to automate the process. This automation requires interoperability between artificial neural networks and prevailing 3D modeling software. The system processes 2D floor plans and outputs parameters of recognized walls, single doors, double doors, and columns. The parameters include the start point and end point of the wall and the center point of the door and column. These parameters are input into Revit 2022 through the Revit API 2022 after post-processing. The dimensional parameter integration affordances of object detection and instance segmentation are studied and compared using Faster R-CNN and Mask R-CNN models. Instance segmentation was found to require more time for data labeling but was more capable of informing the modeling of irregularly shaped objects. The mean Average Precision (mAP) of object detection and instance segmentation are 71.7% and 69.3%, respectively. Apart from single doors, the average precision for other categories falls within the range of 74% to 96%. The results provide software developers with guidance on choosing between object detection and instance segmentation strategies for processing legacy building documents.

The paper presents a comparative analysis of the clamping force on the operating parameters of the SB fastening system. An overview of used elastic fastening systems for prestressed concrete sleepers is presented. The results of laboratory research carried out in accordance with the applicable European standards of the PN-EN 13481 and PN-EN 13146 series are described synthetically. Specially prepared clamp type SB with different stiffness within the range allowed by PKP PLK S.A. were selected for the tests. All tests were done in accredited laboratory. The paper presents the impact of the SB clamp stiffness on the basic parameters of the fastening system, such as the clamping force and longitudinal resistance. A reduced value of the static stiffness of the clamp may fail to fulfill the requirements of the fastening system shown in the Technical Specifications for Interoperability. The risk of non-repeatability of the SB clamp should lead to the development of a solution or even a change to the W-type fastening system.

Within the framework of this project methods are being tested and implemented a) to introduce remote sensing based approaches into the existing process of biotope mapping and b) to develop a framework serving the multiple requirements arising from different users’ backgrounds and thus the need for comprehensive data interoperability. Therefore state-wide high resolution land cover vector-data have been generated in an automated object oriented workflow based on aerial imagery and a normalised digital surface models.These data have been enriched by an extensive characterisation of the individual objects by e.g. site specific, contextual or spectral parameters utilising multitemporal satellite images, DEM-derivatives and multiple relevant geo-data. Parameters are tested on relevance in regard to the classification process using different data mining approaches and have been used to formalise categories of the European nature information system (EUNIS) in a semantic framework. The Classification will be realised by ontology-based reasoning. Dissemination and storage of data is developed fully INSPIRE-compatible and facilitated via a web portal. Main objectives of the project are a) maximum exploitation of existing “standard” data provided by state authorities, b) combination of these data with satellite imagery (Copernicus), c) create land cover objects and achieve data interoperability through low number of classes but comprehensive characterisation and d) implement algorithms and methods suitable for automated processing on large scales.

The measurements of physical level parameters can become the area where decisions about cognitive radio will have the most striking effect. Field-programmable gate array (FPGA) enables real-time analyses of physical layer data to satisfy constraints like dynamic spectrum allocations, data throughput, and the coding rate. Cognitive radio will be based on simple network management techniques, using remote procedure calls. Intelligent knowledge-base system (IKBS) techniques will be used to search the parameter space in selecting changes to the system. Worldwide Interoperability for Microwave Access (WiMAX) PHY-layer functions will be managed cognitively by a FPGA-based controller to optimize the performance of the system. Instead of simple bit loading methods, the global multi-criteria optimization promise possibility to adapt more parameters with respect to several objectives. In this paper, the application of particle swarm optimization to fixed WiMAX-OFDM (Orthogonal Frequency Division Multiplexing) parameter adaptation is presented and compared with the greedy bit loading algorithm.

Current satellite data retrieval systems retrieves data using latitude, longitude, date, time and sensor parameters like wind, cloud etc. To achieve concept based satellite data retrieval like Storm, Hurricane, Overcast and Frost etc., requires ontological concept descriptions using satellite observation parameters and concept based classification of satellite data. The current research work has designed and implemented a two phase methodology to achieve this. The phase 1 defines ontology concepts through satellite observation parameters and phase 2 describes ontology concept based satellite data classification. The efficiency of the methodology is been tested by taking the Kalpana satellite data from MOSDAC and weather ontology. This achieves concept based retrieval of satellite data, application interoperability and strengthen the ontologies.

Full textAbstract:
The inevitable revolution of the Internet of Things (IoT) and its benefits can be witnessed everywhere. Two major issues related to IoT are the interoperability and the identification of trustworthy things. The proposed Context-Aware Trustworthy Social Web of Things System (CATSWoTS) addresses the interoperability issue by incorporating web technologies including Service Oriented Architecture where each thing plays the role of a service provider as well as a role of service consumer. The aspect of social web helps in getting recommendations from social relations. It was identified that the context dependency of trust along with Quality of Service (QoS) criteria, for identifying and recommending trustworthy Web of Things (WoT), require more attention. For this purpose, the parameters of context awareness and the constraints of QoS are considered. The research focuses on the idea of a user-centric system where the profiles of each thing (level of trustworthiness) are being maintained at a centralized level and at a distributed level as well. The CATSWoTS evaluates service providers based on the mentioned parameters and the constraints and then identifies a suitable service provider. For this, a rule-based collaborative filtering approach is used. The efficacy of CATSWoTS is evaluated with a specifically designed environment using a real QoS data set. The results showed that the proposed novel technique fills the gap present in the state of the art. It performed well by dynamically identifying and recommending trustworthy services as per the requirements of a service seeker.

Elliptic Curve Cryptography is considered as the best choice for hardware implementation as it uses shorter keys without decreasing the security level. The performance and level of security are associated with domain parameters. As ECC standards are changing, interoperability and security are the main issues in hardware implementation. This paper presents a run-time reconfigurable architecture for elliptic curve cryptography. By using dynamic partial reconfiguration, various domain parameters and functional blocks can be changed runtime and different security levels are achieved. Also, side-channel information is randomized runtime and attacks can be avoided. The proposed architecture is implemented on ML605 Virtex-6 board, and experimental results show that the Area-Delay-Product is almost the same for the proposed two configurations

Full textAbstract:
Network-centric warfare (NCW) is a concept that prioritizes integration and interconnection between combat elements to improve operational effectiveness. One approach to achieve high interoperability is ESP-NOW communication with mesh network topology. ESP-NOW technology enables fast and efficient wireless communication between devices without Wi-Fi infrastructure or routers. This research implements a mesh network topology using ESP32 modules that support ESP-NOW, where each node can function as a repeater to facilitate communication between devices beyond direct range. Reliability and network coverage testing was conducted by measuring latency and throughput parameters, which showed an average latency of 15 ms and a throughput of up to 2 Mbps, sufficient to support tactical communications in real-time. Although the performance is satisfactory, the obstacles encountered include limited coverage in dense environments and signal interference, which affects the stability of the connection. The study illustrates how the integration of ESP-NOW with mesh improves interoperability within NCW, allowing military units to share real-time data, such as position coordination, situational information, and operational commands. Thus, this implementation has great potential in future military operations, strengthening the integration of combat units and situational awareness on the battlefield.

European rail transport policy aims to create a single railway area. European Union (EU) issues, for this purpose, sets of regulations and directives. Individual countries are involved in its implementation according to their capabilities. The aim of this article is to examine the current state of interoperability in the EU, especially in the Czech Republic, and to compare selected mobile applications regarding the possibility of unifying their design of mobile applications. A systematic literature research review methodology was used. The sources of information were mainly the scientific database Web of Science and the database of EU documents EUR-Lex. When examining one of the main parameters—the use of mobile networks—it was found that all of the selected applications use public mobile networks, none of them uses the Global System for Mobile Communications–Railway (GSM–R) network. This finding confirmed the theoretical assumption that this network is not currently ready for more or less massive operation of mobile applications. The possibility of using the next generation railway mobile network is open for discussion as one of the next steps to ensure interoperability in telematics applications.

The need to address inadequate power supply led to the development of automation strategies to improve the efficiency of power substation. This study conducts a systematic literature on the automation of operational parameters in electrical substation. Initially, 84 articles were retrieved from online as articles and grey literature. Upon the implementation of the inclusion criteria, 31 articles were selected and reviewed due to the fact that their focus and finding match with the aim of this study. The outcome of this study indicates that one of the recent advances in the automation of power substation is the development and implementation of the International Electro-technical Commission (IEC) 61850 standard. The standard boasts of several advantages such high compatibility, interoperability, cyber security features, efficiency, reliability, scalability and centralised control. However, some of its challenges includes time synchronisation standardisation of its testing procedure as well as integration into the communication network architecture. The study may promote the reliability of electrical protection, to reduce load-shedding incidences. It may also assist utilities and other electrical energy industries to better grasp how the automation protocol utilised affects substation efficiency.

В рамках развития цифровой экономики существенно увеличивается объём сенсорных данных от разнородных источников, что приводит к необходимости повышения эффективности управления обработкой сенсорной информации.

Introduction. Currently, the volume of sensor data from heterogeneous sources is significantly increasing. This leads to the need of improving the efficiency of sensor data management by addressing semantic interoperability. The aim of the work was to reduce the errors in interpreting sensor data by comparing and evaluating the similarity between descriptions of the parameters of measurement objects and the concepts used to describe measured quantities and units, utilizing semantic annotations. Methods. The research employs an ontological approach as its primary method. Since most sensor data pertains to the measurement of object parameters, the proposed method involves comparing and assessing the similarity of parameter descriptions based on an ontology of measured quantities, units of measurement, and sensor types. To achieve this, a semantic interoperability system is proposed for the Industrial Internet of Things (IIoT) and sensor systems. Additionally, a sequence diagram is developed to facilitate the exchange of requests and informational messages between IoT devices, the IIoT system, and the semantic interoperability system. Results.The resulting model, developed using expert knowledge, can support import substitution by enabling compatibility with new types of sensors.

Abstract. The conservation of cultural heritage can be affected by different changes in temperature and humidity within architectural spaces, so energy performance and interior microclimate of historic buildings require adaptation to new maintenance and prevention studies. The search for these new investigations brings cultural heritage closer to new digital technologies such as Historic Building Information Modelling (HBIM). In this work, a new interdisciplinary methodology is developed between energy operators and BIM operators, so that a new framework is created to monitor energy parameters through intelligent sensors that measure temperature and humidity in the fully interoperable and semantically enriched 3D model itself. The study's commitment involves solving the interoperability workflow between sensors and the BIM platform, taking advantage of this new interconnectivity. For the study, a methodology applied to the Church of the Sacred Heart of Jesus in Seville was carried out, where from a survey through a georeferenced terrestrial laser scanner with topographic equipment, it is modelled from the point cloud, incorporating the sensors in the HBIM Project. In the workflow, it has been shown that the integration of microclimate data inside churches can be managed directly in the environment of an HBIM-based model and transfer a reverse flow in the process.

PurposeThe operational phase of a building's lifecycle is receiving increasing attention, as it consumes an enormous amount of energy and results in tremendous detrimental impacts on the environment. While energy simulation can be applied as a tool to evaluate the energy performance of a building in operation, the emergence of Building Information Modeling (BIM) technology is expected to facilitate the evaluation process with predefined and enriched building information. However, such an approach has been confronted by the challenge of interoperability issues among the related application software, including the BIM tools and energy simulation tools, and the results of simulation have been seldom verified due to the unavailability of corresponding experimental data. This study aims to explore the interoperability between the commonly used energy simulation and BIM tools and verifies the simulation approach by undertaking a case study.Design/methodology/approachWith Autodesk Revit and EnergyPlus selected as the commonly used BIM and energy simulation tools, respectively, a valid technical framework of transferring building information between two tools is proposed, and the interoperability issues that occur during the data transfer are studied. The proposed framework is then employed to simulate the energy consumption of a single-family house, and sensitivity analysis and analysis on such parameters as schedule are conducted for building operations to showcase its applicability.FindingsThe simulation results are compared with monitored data and the results from another simulation tool, HOT2000; the comparison reveals that EnergyPlus and HOT2000 predict the total energy consumption with a difference from the monitoring data of 8.0 and 7.1%, respectively.Practical implicationsThis research shows how to efficiently use BIM to support building energy simulation. Relevant stakeholders can learn from this research to avoid data loss during BIM model transformation.Originality/valueThis research explores the application of BIM for building energy simulation, compares the simulation results among different tools and validates simulation results using monitored data.

The antenna dimension is reduced substantially with a miniature ground plane. The PIFA array provides a large bandwidth (670 MHz) and a high isolation between its ports less than −26 dB. The proposed antenna has been analyzed and designed with Ansoft HFSS v.11. Then a prototype was fabricated and tested for its performance in terms of bandwidth, S-parameters, and radiation pattern. A parametric study is made to analyze the effect of different PIFA parameters on the operating frequency and the S-parameters. The diversity performances are evaluated using computer simulation technology microwave studio (CSTMWS). The broadband performance and the high isolation are achieved in both simulation and measurement.

Recently, a new wireless technology, i.e., Worldwide interoperability for Microwave Access (WiMAX), has been demonstrated to have its strong potential to provide a very high speed of broadband services. By simultaneously using multiple antennas at transmitter and receiver sites, these systems exploit the spatial dimension of the propagation channel. The development of such antennas includes the design of array antenna, optimizing the array antenna parameters and thereby increasing its performance. This paper mainly focuses on design of single microstrip patch antennae and linear array configurations by optimizing the various antenna parameters such as directivity, gain, Mutual coupling and beamwidth etc., Microstrip array antennae designed and simulated using IE3D for WiMAX application operating at 2.4GHz and the same configurations are also optimized and analyzed. In this analysis, upon comparing the parameters such as gain, directivity, return loss and 3-dB beamwidth quantitatively it is proposed that the linear array promises very narrow beamwidth with optimized gain.

Full textAbstract:
This article captures the current trends in the development of communication interoperability and common data modelling for the integration of devices into Industry 4.0 networks. The use of open standards such as the Open Platform Communications Unified Architecture (OPC UA) or the Asset Administration Shell (AAS) concept is the only way to achieve global communication and semantic interoperability. This article presents an original methodology of AAS implementation into an embedded system, dramatically reducing system requirements. The proposed workflow of the I4.0 component creation includes a procedure for the implementation of the AAS in the OPC UA information model. This methodology was verified by creating an intelligent sensor as a specific I4.0 cyber-physical system based on the 32 bit Arm Cortex Microcontroller. The outcome is the AAS as an “Embedded Industry 4.0 Component” hosted by a minimalist hardware; this is the very first design and implementation of a device with such parameters. Compared to recent studies (which implement certain types of AAS devices), the system requirements of the proposed embedded AAS are in the order of hundreds lower. The presented novel methodology enables developers and industrial manufacturers to implement relatively simple devices (e.g., smart sensors or actuators) as I4.0 Components.

Full textAbstract:
A major challenge in the development of multi-vendor HVDC networks are converter control interactions. While recent publications have reported interoperability issues such as persistent oscillations for first multi-vendor HVDC setups with AC-side coupling, multi-terminal HVDC networks are expected to face similar challenges. To investigate DC-side control interactions and mitigate possible interoperability issues, several methods based on the converters’ and DC network’s impedances have been proposed in literature. For DC network’s impedance modelling, most methods require detailed knowledge of all converters’ design and controls. However, in multi-vendor HVDC networks, converter control parameters are not expected to be shared due to proprietary reasons. Therefore, to facilitate impedance-based stability analyses in multi-vendor MTDC networks, methods that do not require the disclosure of the existing converter controls are needed. Here, detailed impedance measurements can be applied; however, they are time-consuming and require new measurement for a single configuration change. This paper proposes an equivalent impedance calculation method suitable for multi-vendor DC networks, which for available black-box models or converter impedance characteristics can be modularly applied for various network configurations, including different control settings and operating points, while significantly reducing the required time for obtaining an equivalent DC network impedance.

Full textAbstract:
Industrial Internet of Things focuses on the manufacturing process and connects with other associated concepts such as Industry 4.0, Cyber-Physical Systems, and Cyber-Physical Production Systems. Because of the complexity of those components, it is necessary to define reference architectures models to manage Industry 4.0 and the Industrial Internet of Things. The reference architecture models aim to solve the interoperability problem enabling the syntactical and semantic levels of interoperability. A reference architecture model provides a bottom/top view of an industrial process, from the physical transducers at the physical layer to the business layer. The physical layer provides access to a twin representation of a physical thing in the digital world, extending the functionalities in the manufacturing process. This paper studies the syntactic interoperability between the IEEE 1451 and IEC 61499 in an industrial environment. The IEEE 1451 family of standards has the essential characteristics to support the information exchange between smart transducers (sensors and actuators), building the digital elements and meeting the Industry 4.0 requirements. The IEC 61499 standard enables industrial control and automation. These two standards combined at the syntactic level solve an interoperability problem. The IEC 61499 also provides data to the framework layer, supplying all the parameters defined for the communication layer specified by a reference architecture model. This paper combines the IEEE 1451 with the IEC 61499, enabling data exchange in a reference architecture model proposed for Industry 4.0. Network performance at the communication level of a reference architecture model in a local network and an external network is evaluated for the proposed application. The IEEE 1451 standard implementation and adoption to acquire data and communicate it inside an industrial process allowed the IEC 61499 standard to control an industrial process. The IEEE 1451 standard is implemented in a MSP430 low power microcontroller. A Raspberry Pi running FORTE and 4diac in the USA and Portugal were used to test a local network in Portugal and an external network in USA. Data related to network performance was obtained with Wireshark and processed with MATLAB. Tests using the Message Queuing Transport Telemetry Transport and Hypertext Transport Protocols verified the performance of these protocols, supported by the IEEE 1451 and IEC 61499 standards, showing that communication inside an Industry 4.0 environment is possible. MQTT protocol is faster, has a small packet size, and consumes less bandwidth. The HTTP protocol uses more bandwidth but is more reliable for real-time communication, essential for Industry 4.0.

Internet of Things (IoT) is connected everywhere and enables massive information exchange between objects and people. The unified global IoT must manage a massive amount of data generated by these connected smart which arises the interoperability challenges such as lack of communication protocols, device support, and accepted open standards in smart environments. To combat these issues, a novel Smart-Fuzzy linked rules for Cross Domain application (Smart-FCD) framework is proposed to ensure interoperability by enabling efficient communication and data exchange between multiple platforms and systems. Initially, the heterogenous data from the sensors such as temperature sensors and humidity sensors, and the descriptions are implemented according to the Sensor Measurement List (SenML) language. After composing, semantic modelling will occur which converts the relational data into Resource Description Framework (RDF) format. The Linked Open Vocabulary for the Internet of Things (LOV4IoT) dataset is used to extract interoperable domain knowledge, which is then fed into the related sensor-based fuzzy rules. The IoT preset semantic models which utilise interoperable datasets and domain instances, which are updated via fuzzy association rules. Semantic Web of Things (SWoT) is a technology that assists in creating semantic-based IoT applications, thus IoT developers may use it to create intelligent applications. The sensor data, RDF simulation, evolution time and latency are some of the parameters that are used to evaluate the effectiveness of the proposed Smart-FCD methodology.

Abstract This paper experiences the potential of the use of Building Information Modeling (BIM) technique as a strategy to facilitate the energy performance analysis of existing buildings with historical relevance. The relationship between BIM and sustainability is an emerging concept which is becoming more and more interesting in the construction industry. The different methods for energy modeling of buildings provided in the literature usually imply the use of dynamic simulation software, such as EnergyPlus and TRNSYS, whose graphical interfaces are essential and not particularly user-friendly, if compared to the more popular CAD. Modelling in BIM environment, on one hand, helps to speed up certification procedures and, on the other hand, to define a new work philosophy during the design of energy efficiency interventions, thanks to the software’s interoperability. This study focuses on the analysis of the energy performance of the Maritime Station of Napoli, in southern Italy, located in the Angevin wharf and hosting the port terminal. The procedure employed for the study is a BIM working procedure, therefore involving different software tools. The authors have analyzed and compared the results obtained with different tools, to verify the efficiency of their interoperability, together with the parameters that most influence the analysis. Finally, the authors evaluate the dependency of the results from climatic conditions, conducting the analysis for other two Italian cities, located in different Italian climatic zones.

The exponential rise in global healthcare challenges; the rise in morbidity and mortality, especially in developing countries have compelled stakeholders to explore alternative ways of overcoming the crisis. Guided by the recommendation of WHO (2013), efforts have been directed towards prevention, response and strengthening of the existing healthcare systems. There have also been efforts to explore the potential of mobile technology towards healthcare provision, with numerous mHealth projects being reported across the developing world. Reports indicate that a significant number of these solutions have failed before realizing the primary goals, pointing to a possible mHealth sustainability challenge. The study explored literature covering global health challenges, use of mobile technology healthcare solutions in developing countries as well literature covering evaluating technology sustainability. Through the review, key factors that influence sustainability of technology were identified. A cross-sectional survey using questionnaires and a qualitative exploratory study using interviews and Focused Group Discussion, targeting mHealth stakeholders were used to map and contextualize the identified sustainability factors to the developing country context. The identified factors were categorized into three broad categories; Individual factors; User Satisfactions, Access to system, and User Support, Technological Factors; System Quality, System Scalability, Technology Sustainability, Technology Relevance and System Interoperability and Management Factors; mHealth Ownership and Net Benefits (Return on Investment). The paper identifies challenges in the sustainability of mHealth systems in developing countries; using Kenya health sector as a case study and propose sustainability evaluation parameters for mHealth systems in developing countries.

In this paper, a multiple-input multipleoutput (MIMO) antenna with high isolation is designed using defected ground structure (DGS). The proposed antenna is constructed by two sets of four elements (2×2), which are designed at the central frequency of 3.5 GHz for Worldwide Interoperability for Microwave Access (WiMAX) applications. The antenna is fabricated on a FR4 substrate with an overall size of 144 × 99 × 1.6 mm. Thanks to DGS, the designed MIMO antenna achieves a high isolation of 30 dB and a high radiation efficiency of over 90%. Besides, this MIMO antenna attains a 7.5 dBi gain. There is a good agreement between the simulated S-parameters and the measurement results.
