Secrecy Rate Analysis for the Cooperative Communications 12

Secrecy Rate Analysis for the Cooperative Communications

Due to the character of low cost and easily to implemented, the cooperative communication is the future tendency. Three fundamental mode, Amplify-and-Forward (AF) mode, Decode-and-Forward (DF) mode and Compress and Forward (CF) mode are employed to the system. In the cooperative system, relays function to transmit the delivered signal to the destination. Each node in the system could play as the source station, the relay and the destination station. Currently, the issue of privacy and security are seriously requested in the communication. There could be the eavesdroppers pre-tend as the relay to steal the message. Hence, the secrecy protection becomes important. In the higher layer, the encryption scheme is applied to protect the message. However, it is difficult for those devices with low computing resources, the example of IoT (Internet of Things). With Shannon Theory, a secure communication could be supported with a positive secrecy rate. Hence, secure cooperative communication could be possible if there exist a positive secrecy rate between the two ends in the transmissions. Base on the secrecy rate analysis, the maximum secrecy rate is the initial step toward a secure communication. In the cooperative system, the delivered signal could be transmitted via relays. Hence, the path from the source to the destination could be a huge combination. With the exhaustive method to find the optimal secrecy rate could be realized. Hence, in this work, the numerical experiment, the AF and DF mode cooperative mode is adopted. © 2023 IEEE.

The paper is dedicated to the analysis in the frequency domain of the currents (in common mode and differential mode) which generate conducted emissions in the supplying cable of the equipment containing a switch mode power supply (SMPS). The performed simulation considers the standard CISPR 16-1-2 which refers to specifications, methods, and test apparatus for the measurements of disturbances and immunity to conducted emissions. One proposes solutions to limit and control the conducted emissions generated by the SMPS within the supplying cable that result into noise currents and high frequency currents within the range 150 kHz - 30 MHz that might interfere with other elec.ric equipment. Various ways to limit the mentioned emissions are simulated and analyzed. The influence of the duty-cycle over the frequency spectrum from the conducted emissions range is considered and the worst case is determined. The conclusion is that the optimum filtering solution involves the use of an EMI filter, the results being compared to the CISPR 22 standard. © 2023 IEEE.

Model-Driven eng.neering for High-Performance Parallel Discrete Event Simulations on Heterogeneous Architectures 24

Proceedings of the Winter Simulation Conference

Modern high-performance, large-scale simulations require significant computational power, memory, and storage, making heterogeneous architectures an attractive option. The presence of accelerators in heterogeneous architectures makes model development hard. Domain-specific languages (DSLs) have successfully simplified model development, but designing a DSL to target heterogeneous architectures can be burdensome. Model-driven eng.neering (MDE) can simplify the development of DSLs targeting heterogeneous architectures. In this paper, we focus on MDE and propose a model-driven approach targeting Parallel Discrete Event Simulations on heterogeneous architectures. We exercise our MDE-generated models using a state-of-the-art runtime environment for heterogeneous architectures.

In today’s dynamic markets, decision-making relies heavily on simulation models to evaluate different production control methods. Although price-driven production control methods have proven their effectiveness in exploiting price volatility, certain industries are still reluctant to adopt these methods in their operational decision-making. This research demonstrates the relevance of price-driven methods for the wood products industry. A sawmill simulator is used to illustrate this. Since the simulation of the sawmill production process is time-consuming, we propose a probabilistic sampling-based method to rationalize the dataset size. A comparative study shows that exploiting historical and recent price data increases sawmill revenues. © 2024 IEEE.

Automatic judgment of the presence or absence of cancer metastasis to lymph nodes is an important topic in cancer staging to reduce the burden of medical doctors to check a large number of CT images. Therefore, the machine learning approach becomes helpful and desired. However, using CT images for machine learning requires annotation by a special radiologist, and it is difficult to prepare a large dataset. In recent years, many approaches to the generation of images by machine learning have been proposed and applied to medical images. In this paper, we propose a method to generate images around a lymph node in an arbitrary metastatic state using a diffusion model, which is a generative model that is gaining attention on behalf of GAN. Experiments were also conducted to learn the classification of cancer metastasis using the generated images for data augmentation, showing that the generated images are effective in improving classification performance. © 2024 IEEE.

Checking Model Consistency in Service-Oriented Systems

Service-oriented architecture (SOA) and serverless computing have emerged as foundational technologies for modern IT systems, such as e-commerce platforms, banking and insurance solutions, healthcare applications, and gaming systems. As these systems grow in complexity and scale, there is an increasing demand for advanced modelling approaches that enable software eng.neers to verify and simulate system components during the development and maintenance phases. The goal of our research is to apply Model-Driven eng.neering (MDE) techniques to build multi-faceted models of service-oriented systems, in order to ensure that transactions occur as expected, and ultimately evaluate whether a proposed design meets the goals and requirements of stakeholders. In this paper, we present work towards a prototype framework that leverages sequence diagrams, activity diagrams and goal models to represent the behaviour of the actual system as well as the intents of its stakeholders. The proposed framework aims to ensure the correctness and consistency among these multifaceted models, and any design changes are reflected in these models early in the software lifecycle, potentially uncovering noncompliant or unintended events and interactions.

The Unlimited Sensing Framework (USF) was recently introduced as an alternative for capturing high-dynamic-range analog signals. It incorporates a modulo non-linearity prior to sampling and algorithmically unfolds the signal during the reconstruction step, thus avoiding problems caused by sensor saturation. In this paper, we focus on the quantization problem in the context of USF. We build upon the existing method which enables reconstruction from 1-bit modulo samples obtained via Sigma-Delta quantization. We show that by implementing some changes in the acquisition scheme it is possible to enhance the reconstruction accuracy to the extent that the modulo folding introduces no additional error contribution. © 2024 IEEE.

The analysis of facial expressions is a powerful tool to decode nonverbal behavior in humans. Due to its importance, several studies have already been done in the past. However, facial expression recognition on wild and multi-label faces is under-investigated also due to the limited number of available databases. This paper fills in the current lack by challeng.ng the RAF-ML dataset and fixing the state-of-the-art performance of 50.5% on the "single label experiment". The proposed method is also tested in a second experiment, suggested by this work, which considers only wild faces having a dominant expression. The benchmark performance for the second trial is 56.1%. The deep-learning algorithms presented in this work are described in detail to facilitate their reproduction.

In the networks, Situation Awareness (SA) is a new concerned issue for the security. Usually, SA implementation includes three stages. They are the knowledge of SA, the situation estimation of SA and the situation prediction of SA. Among these stages, the situation prediction is the most difficult and treasured. Prior predicting, the situation estimation has to be established first. The major concerns in this work are to propose the methods to establish the model to estimate SA, to apply Dempster-Shafer theory to estimate SA. Finally, based on the knowledge and databases from the experts and experiences, the performance evaluation is proposed. © 2023 IEEE.
