There have been many compression standards developed during the past few decades and technological advances has resulted in introducing many methodologies with promising results. As far as PSNR metric is concerned, there is a performance gap between reigning compression standards and learned compression algorithms. Based on research, we experimented using an accurate entropy model on the learned compression algorithms to determine the rate-distortion performance. In this paper, discretized Gaussian Mixture likelihood is proposed to determine the latent code parameters in order to attain a more flexible and accurate model of entropy. Moreover, we have also enhanced the performance of the work by introducing recent attention modules in the network architecture. Simulation results indicate that when compared with the previously existing techniques using high-resolution and Kodak datasets, the proposed work achieves a higher rate of performance. When MS-SSIM is used for optimization, our work generates a more visually pleasant image.

Real-time systems are becoming ever more widely used in life-critical applications, and the need for fault-tolerant scheduling can only grow in the years ahead. This article presents a novel fault tolerance approach for tolerating transient faults in hard real-time systems. The proposed approach combines both checkpointing with rollback and active replication to tolerate several transient faults. Based on this approach, a new static fault-tolerant scheduling algorithm SFTS is presented. It is based on a list of scheduling heuristics which satisfy the application time constraints even in the presence of faults by exploring the spare capacity of available processors in the architecture. Simulation results show the performance and effectiveness of the proposed approach compared to other fault-tolerant approaches. The results reveal that in the presence of multiple transient faults, the average timing overhead of this approach is lower than checkpointing technique. Moreover, the proposed algorithm SFTS achieves better feasibility rate in the presence of multiple transient faults.

This article discussed multiple energy flow simulation technology based on the research status of integrated community energy system. Under the unified platform architecture, simulation, planning, optimization, and analysis of distribution multiple energy flow are realized. According to the idea of three cascades of energy utilization, the modeling of equipment in various professional fields is completed under unified software architecture, and the simulation system is finally developed. The system is built with plug-in software, which is open and extensible. The simulation system developed in this paper can be used in the simulation of distribution integrated energy system to realize the interaction between energy flow and information flow.

Software developers who are blind and interact with the computer non-visually face unique challenges with information retrieval. We explore the use of speech and Braille combined with software to provide an improved interface to aid with challenges associated with information retrieval. We motivate our design on common tasks performed by students in a software development course using a Microprocessor without Interlocked Pipeline Stages (MIPS) architecture simulation tool. We test our interface via a single-subject longitudinal study, and we measure and show improvement in both the user’s performance and the user experience.
