DSP Processer-in-the-Loop Tests Based on Automatic Code Generation

The digital signal processing (DSP) processor-in-the-loop tests based on automatic code generation technology are studied. Firstly, the idea of model-based design is introduced, and the principle and method of embedded code automatic generation technology are analyzed by taking the automatic code generation of the DSP control algorithm for pulse width modulation (PWM) output as an example. Then, the control system model is established on MATLAB/Simulink. After verifying the model through simulation, the target board platform is established with DSP as the core processor, and the automatically generated code is tested by the processor-in-the-loop (PIL). The results show that the technology greatly shortens the development cycle of the project, improves the robustness and consistency of the control code, and can be widely used in the complex algorithm development process of the controller, from intelligent design and modeling to implementation.

5 Sulfur Fluoride Exchange (SuFEx)

Sulfur Fluoride Exchange (SuFEx) click chemistry is a new generation technology for creating stable molecular connections with absolute reliability under metal-free conditions. SuFEx builds upon the fundamental principles of click chemistry by exploiting a unique blend of stability and latent reactivity of high oxidation state sulfur fluoride [e.g., S(VI)] functionalities to forge stable covalent linkages at connective SuFEx hubs. In this review, we focus mainly on the SuFEx hubs, sulfuryl fluoride (SO2F2), thionyl tetrafluoride (SOF4), ethenesulfonyl fluoride (ESF), 1-bromoethene-1-sulfonyl fluoride (BESF) and, 2-substituted alkyne-1-sulfonyl fluorides (SASFs). We describe each connector’s unique reactivity and their application to SuFEx click chemistry.

Recent Advances, Practical Challenges, and Perspectives of Intermediate Temperature Solid Oxide Fuel Cell Cathodes

As a highly efficient-clean power generation technology, intermediate temperature (600-800 °C) solid oxide fuel cells (IT-SOFCs) have gained much interest due to their rapid start-up and shut-down capability, longer life-time...

The Potential of Hydro Renewable Energy Technology to Electricity Remote Villages in Papua and Maluku Islands, Indonesia

The islands of Papua and Maluku are eastern Indonesia which consists of remote islands and villages. The Papua Islands consist of 3,749 islands divided into two provinces, namely Papua and West Papua, while the Maluku Islands are 1,735 islands into two provinces of Maluku and North Maluku, the number of inhabited islands in Papua and Maluku around 230 islands and around 100 newly electrified islands. The electrification ratio for Papua is 47.69%, West Papua is 89.94%, Maluku is 87.02% and North Maluku is 88.68%. The electrification ratio is still below the national average. Maluku Islands and Papua Indonesia has abundant renewable energy natural resources, namely hydro potential. The total hydro energy potential of Papua and Maluku is 808 MW. To overcome this shortage of electricity, it is necessary to develop a renewable energy generation system according to the potential of the area, namely hydro power. Energy generation technology that is environmentally friendly, efficient, effective, and reliable can be a solution for electrification in Papua and Maluku. Hydro power plants using vortex turbines, picohydro turbines and axial turbines for permanent magnet generators can be a solution to electrify areas or villages remote in Papua and Maluku.

Numerical Investigation of Cathode Structure Influence on Electrochemical Behavior of Lithium-Sulfur Battery

Nowadays, Lithium-Sulfur batteries are often considered as the next generation technology for energy storage systems. This article investigates the influence of the size of sulfur clusters present in the cathode on the battery overall electrochemical behavior. The properties of the cathode are studied by cyclic voltammetry simulations using a custom numerical model implemented into Ansys Fluent. The simulation is supplemented by experimental cyclic voltammetry measurements and images from a scanning electron microscope.
