The use of sub-millimeter wave radiometer on the geostationary orbit meteorological satellite is of great significance to the study of the Earth's atmosphere. This paper presents a single-channel quasi-optical network system around 325GHz. The diffracted Gaussian beam analysis method (DGBA) and a three dimensional visual software based on it are used. This design is used in the sub-millimeter radiometer...
An integrated method of CAD, CAE and multi-objective optimization is proposed in this paper. It integrated prototype modeling, FEM analysis and optimization procedures. In this method to design a new product, only inputs and outputs need to be defined, which resembles to a black-box. In order to validate this method, design and optimization of a manipulator in a cherry-picker are developed as a case...
This paper establishes a framework of Multi-Agent System (MAS)-based collaborative assistant design system which is applied to the Machining Center (MC), provides an expanded Object-Oriented Knowledge Representation (OOKR) for the cases storage, presents an effective reasoning algorithm for the chosen of appreciate production type according to the customization, and illustrates a prototype case study...
The advantages and the flexibility introduced into the hardware implementation by partial dynamic reconfiguration have rapidly changed the design flow of embedded systems. Configuration management is an important issue in operating system for dynamically reconfigurable system-on-chip. Reconfiguration overhead affects the performance of reconfigurable system. This paper presents a hardware implemented...
Reconfigurable system provides both flexibility of software and performance of hardware. It is a significant trend in embedded application domain. Some new reconfigurable technologies and technology-dependent tools have been developed, but the whole design flow for run-time reconfigurable systems with real-time operating system support is not proposed. RTOS plays an important role in the system and...
Nowadays, one of the challenges for creating a mixed hardware/software application on dynamically reconfigurable SoC is how to provide a unified programming model for hybrid hardware/software tasks and a portable interface adaptation for dynamically reconfigurable hardware tasks. In this paper, a POSIX-compliant hardware thread interface is proposed for data stream driven applications, serving for...
Dynamic partial reconfigurable embedded system includes at least one reconfigurable device, which is emerging as the new paradigm for satisfying the simultaneous demand for application performance and flexibility. But it brings difficulties in debugging, testing and performance measurement at the same time. Monitoring is an effective approach in debugging, testing and performance measurement in such...
