Power Control System Design for a Heat Pipe Cooled Reactor

Due to the small size, the high-power density and the strong environmental adaptability, the heat pipe cooled reactor has a broad application prospect in the fields of space exploration, underwater vehicle power system and other fields[1]. It will be one of the subversive technologies which will change the future nuclear power development. The safe operation of the heat pipe cooled reactor requires an effective power control system. 3KeyMaster is a comprehensive real-time simulation analysis platform and the control system can be built by using its logic module. The interface program can be developed in its task program, and other program can be integrated in this platform[2]. The system program of the heat pipe cooled reactor has compiled as a dynamic linking library. Through the task program of the 3KeyMaster simulation platform to call the dynamic linking library by using C++ program, the system program is coupled with the 3KeyMaster simulation platform. The modules of 3KeyMaster platform exchange data with the system program by shared memory. Through the responses of the temperature due to step change in the reactor power obtained by 3KeyMaster, the transfer functions are obtained by using the system identification module in MATLAB & Simulink. The power disturbance is introduced, and simulation is carried out on the 3KeyMaster. The changes of the important parameters are analyzed to obtain its dynamic characteristics. Based on the dynamic analysis on the system responses, the control strategy for the power control system is proposed. The power control system is implemented in MATLAB & Simulink. The control system parameters are tuned to determine a group of suitable control parameters[3]. Finally, the control performance of power control system is evaluated by simulations.

Consuming Images

The American television commercial exhibits an aesthetic and historical dynamic linking it directly to cinematic and media cultures. Consuming Images: Film Art and the American Television Commercial establishes the complex vitality of the television commercial both as a short film and as an art form. Through close and comparative readings, the book examines the influence of Hollywood film styles on the television commercial, and the resulting influence of the television commercial on Hollywood, exploring an intertwined aesthetic and technical relationship. Analysing key commercials over the decades that feature new technologies and film aesthetics that were subsequently adopted by feature filmmakers, the book establishes the television commercial as film art.

iSEE: Interactive SummarizedExperiment Explorer

Data exploration is critical to the comprehension of large biological data sets generated by high-throughput assays such as sequencing. However, most existing tools for interactive visualisation are limited to specific assays or analyses. Here, we present the iSEE (Interactive SummarizedExperiment Explorer) software package, which provides a general visual interface for exploring data in a SummarizedExperiment object. iSEE is directly compatible with many existing R/Bioconductor packages for analysing high-throughput biological data, and provides useful features such as simultaneous examination of (meta)data and analysis results, dynamic linking between plots and code tracking for reproducibility. We demonstrate the utility and flexibility of iSEE by applying it to explore a range of real transcriptomics and proteomics data sets.

Optimizing Students' Information Processing in Science Learning

This chapter discusses a theoretical framework for designing effective visual learning in science education. The framework is based on several theories related to cognitive visual information processes and empirical evidence from authors' previous research in visual-based science learning. Emphasis has been made on the structural part of the framework that allows dynamic linking to critical factors in visual learning. The framework provides a new perspective by identifying the variables in visual learning and the instructional strategies aiming at the improvement of visual performance. The discussion of the theoretical and practical significance of the framework is made, followed by suggestions for future research.
