In this work, we designed a micro-hotplate for MEMS gas sensor wafer level packaging. It changes the current package structure. we built a thermal- electromechanical-mechanical simulation model. Based on this model, we compared Oxide-Nitride-Oxide (ONO) supporting layers and finally chose ONO due to the balanced thermal and mechanical performances. the micro-hotplate was fabricated by MEMS process. After testing, the performance of micro- hotplate samples meets the design requirements. the optimized micro-hotplate with wafer level packaging not only has the advantages of low power consumption, but also realizes the high-density integration of multiple independent temperature- controlled micro hotplates, which is expected to be widely used in the future, especially for Micro-electromechanical systems (MEMS) gas sensor.

In this paper, we present state feedback control for the distributed radar with packet dropouts and time-varying delays. the delays are time-varying. the packet dropouts mean the loss of the state measurement data. Firstly, the state feedback control design is transformed into stability analysis for a 2D stochastic system. Secondly, we obtain the stability condition based on linear matrix inequality (LMI) of mean-square asymptotic stability of the 2D stochastic system. And we give the method to get the law for the state feedback control design. the proposed method can stabilize the distributed radar with packet dropouts and time-varying delays. Finally, a numerical example is to show the validity of the methods. © 2023 IEEE.

Traditional computer networks provide a best-effort packet delivery service. Packets may be lost or delayed due to network congestion or security threats. Deterministic Networking (DetNet) aims to provide consistent and predictable delivery of data packets in real-time with extremely low data loss rates, bounded latency and jitter. Deploying DetNet in a standard IP based network presents multiple technical challenges and security concerns [1]. this paper presents a security solution that ensures the authentication and integrity protection for the DetNet data plane. We have implemented using the Data Plane Development Kit (DPDK) an efficient computation of the DetNetAuth header - a simplified version of the Authentication header [2] - that will be added after the layer 3 headers. the DetNetAuth header computation process is significantly accelerated compared to the state of the art IPSec Authentication Header (IPSec AH). the optimization technique involves pre-computing intermediate results for the HMAC function and the utilization of solely the layer 3 headers and the secret key for the HMAC computation. Our implementation can be used in networks where deterministic flows are desired, as it provides protection to a wide range of attacks: Replication-related (header manipulation), Spoofing and Replay attacks.

Intrusion Detection systems (IDS) constitute a critical line of defense in contemporary cybersecurity efforts, designed to identify and counteract unauthorized access and malicious activities within computer networks. Leveraging the capabilities of Machine Learning (ML) algorithms, IDS endeavors to distinguish potentially harmful alterations and security breaches. this study delves into the pivotal question of algorithm selection for optimal performance. Machine Learning-based Intrusion Detection systems (ML-IDS) are designed not only to enhance overall system security but also to strike a balance between minimizing false alarms and maximizing true alarm rates. To address this, we empirically evaluate five ML algorithms and present their performance in the context of network intrusion detection. those algorithms are as follows: Random Forest achieves an impressive accuracy rate of 99.88%, Gradient Boosting demonstrates robust performance at 99.76%, AdaBoost exhibits an accuracy of 90.00%, Decision Tree boasts a noteworthy accuracy of 99.80%, and Extremely Randomized Trees demonstrate substantial proficiency with an accuracy of 99.86%. this empirical exploration enriches our comprehension of these algorithms and offers critical insights to enhance the security of computer systems. © 2023 IEEE.

Considering the pressure of communication facilities, the difference in willingness to participate, privacy protection, and other factors, a temperature control load demand response control strategy based on signal broadcasting considering the difference in user willingness is proposed. the control strategy is divided into the aggregator side and the local temperature control load unit side and its response index are sent by the aggregator to all temperature control load units in the form of signal broadcasting. In this control strategy, considering the variety of temperature control load units and different temperature control intervals, a universal temperature normalization value is established. the user participation willingness coefficient is introduced, and the expression of the actual participation probability of the temperature control load is constructed. According to the comparison result with the random number, whether to start or stop the temperature control component is selected. Finally, the overall application flow of temperature control load demand response is designed, and the effectiveness of the strategy is verified by MATLAB simulation.

One of the most important issues in modern educational activities is equal opportunities in learning for different students and persons, having various social, technical, and economic conditions or limitations. To achieve such goal, we propose to use different classes of cognitive information systems, which perform cognitive resonance processes, and allow to support visual data understanding and semantic content evaluation. Such systems can facilitate learning activities at different levels, and have a positive influence on education processes, by improving perception abilities for students. In particular cognitive information systems will be proposed as a tool for creation of user-oriented learning protocols. Such protocols consider users' perception capabilities, and can be dependent on external features, in which person try to acquire some new knowledge, abilities and competence.

the rise of mobile devices has revolutionized the way we interact with technology, enabling us to carry powerful computing devices in our pockets. However, with the increasing amount of sensitive information stored on these devices, trust has become a crucial factor in mobile security. Fingerprinting, which utilizes sensors embedded in mobile devices to recognize the unique characteristics of the user, has emerged as a promising approach to enhancing trust in mobile devices. Rapid response capability is crucial for the structure of a Peer-to-Peer system, as the nodes within the network have the flexibility to enter or exit at any moment without prior notification. this paper presents a novel approach to trust and reputation of mobile devices that use sensor fingerprinting techniques. Our approach uniquely identifies the nodes in a Peer-to-Peer network based on a spherical overlay such as TSPeer. We also discuss the challenges and limitations of this approach and evaluate it through simulation with real-life data sets.

the advancement of communication technology has created opportunities for coordinating adjacent segments on the highway. Centralized-distributed control has been shown to improve highway traffic efficiency. To fully coordinate cyber resources and physical resources, this paper proposes a dynamic centralized-distributed control strategy. this strategy adapts the communication structure of highway Cyber-Physical systems (CPS) to physical traffic status. By reducing the cyber space dimensions, it reduces computational and communication costs. Additionally, Model-Based systems Engineering (MBSE) is employed to enhance comprehension and management of the intricate aspects of highway CPS. Driven by requirements, the highway CPS is decoupled into system and subsystem levels, enabling independent analysis and design of their respective behaviors, structures, and parameters. Simulation validates the proposed strategy, showing a better balance of traffic efficiency, communication, and computational cost compared to control methods for static structures. © ASCE.

the aim of this paper is to deliver an overview of the present global context about the quality of life and provide key insights about choosing a place to live. Housing affordability and quality of life have become emergently important issues, with a growing concern about global inequality. this paper aims to provide a comprehensive analysis of the global quality of life by examining the relationship between housing affordability, life quality indexes, and the global socio-economic landscape. Data from multiple trusted sources was analyzed and collected, including the WorldBank, UnitedNations, and various statistical agencies, to gain insights into the current state of housing affordability and quality of life across countries. Metrics such as happiness, life expectancy and average income are clustered into patterns that are curated with qualitative research consisting in the latest literature in economic, political, and social aspects of the world outlook. the analysis revealed that there is a significant relationship between housing affordability and quality of life. It was found that countries with better housing affordability tend to have higher quality of education, healthcare and stability. the disparities were more significant between developed and developing countries, -with some interesting outliers.

this user study addresses the characteristics of breast cancer risk factor analysis quizzes in order to understand the correlation between completion time, question clarity, and user satisfaction. the user study was conducted with 10 participants to understand what users find preferable in their overall experience with cancer risk factor analysis tools. three risk factor analysis tools (one of them created by us) were compared in terms of completion time, completion time per question, questions asked to the coordinator, and preferred tool and/or features preferred. Results showed that shorter completion time is not necessarily preferred by users but understanding and clarity of questions enabled users to complete the questionnaires with less confusion. However, results were inconclusive regarding completion time per question as the tools had similar results and, perhaps surprisingly, the most preferred tool was the one with the longest average completion time per question.
