Energy Management in Microgrids: A Combination of Game Theory and Big Data‐Based Wind Power Forecasting

Energy internet provides an open framework for integrating every piece of equipment involved in energy generation, transmission, transformation, distribution, and consumption with novel information and communication technologies. In this chapter, the authors adopt a combination of game theory and big data to address the coordinated management of renewable and traditional energy, which is a typical issue on energy interconnections. The authors formulate the energy management problem as a three‐stage Stackelberg game and employ the backward induction method to derive the closed‐form expressions of the optimal strategies. Next, we study the big data‐based power generation forecasting techniques and introduce a scheme of the wind power forecasting, which can assist the microgrid to make strategies. Simulation results show that more accurate prediction results of wind power are conducive to better energy management

Hospital information system based on micro-service architecture

Hospital Information Systems (HIS) play a critical role in healthcare facilities by managing patient data and streamlining administrative and clinical operations. In recent years, microservice architecture has emerged as a popular approach to designing HIS systems. This article will discuss the advantages of microservice architecture for HIS systems and its implementation

Realizing real-time video conferencing system based on WebRTC and P2P algorithm

This paper presents a solution for realizing a real-time video conferencing system, which utilizes WebRTC technology and P2P algorithm to establish a distributed topology that reduces the burden on servers and allows direct communication between nodes. The ABR algorithm is used to adjust the video bit rate to adapt to different network conditions. In addition, optimization strategies such as bandwidth adaption, data caching and packet loss retransmission are applied to improve video transmission quality

Information system design based on microservice architecture

In recent years, microservice architecture has become the mainstream approach to modern information system design, and the central idea of this architecture is to improve the scalability, reliability and maintainability of the system by splitting it into small, independent service units. This paper introduces the main ideas and practices of information system design based on microservice architecture, including service splitting, service communication, service governance and service deployment. In addition, this paper analyzes the advantages and disadvantages of the current microservice architecture, and illustrates how to design and implement information systems based on microservice architecture in practical applications with real cases

High MMP-9 Expression May Contribute to Retroprosthetic Membrane Formation after KPro Implantation in Rabbit Corneal Alkali Burn Model

Purpose. To evaluate aqueous humor MMP-9 levels in alkali-burned rabbit cornea following KPr implantation and their roles in RPMs formation. Methods. Left eyes of 36 rabbits received a deep corneal alkali wound. 12 corneas were implanted with KPro and the other 24 control corneas were either penetrating keratoplasty or left without keratoplasty. Aqueous humor MMP-9 and TIMP-1 levels were determined and RPMs were obtained for histopathological and ultrastructural examination. Results. Alkali exposure induced significant increase in aqueous humor MMP-9 level and the data were further enhanced by KPro implantation. By contrast, TMIP-1 levels in aqueous humor showed a decreased trend following corneal alkali burn and KPro surgery. RPMs were developed in 5 out of 10 cases of KPro successfully implanted eyes. Histopathology showed the presence of a large number of fibroblasts and collagen fibers arranged irregularly with inflammatory cells infiltration, and an ingrowth of new blood vessels in this retrokeratoprosthesis fibrous tissue. Immunohistochemical analysis showed positive stain of RPMs for both MMP-9 and TIMP-1. Aqueous humor MMP-9 levels were significantly higher in RPM group postoperatively, while TIMP-1 levels were comparatively lower than that of No-RPM group. Conclusions. Our study evidenced the potential pathophysiological role of MMP-9 expression in RPM formation following KPro implantation
