There are plentiful attempts for increasing the efficiency, generality and optimality of the Design Space Exploration (DSE) algorithms for resource allocation problems of distributed embedded systems. Most contemporary approaches formulate DSE as an optimization or SAT problem, based on a set of predefined constraints. In this way, the end users lose the flexibility to guide and customize the exploration...
The blind watermark extraction algorithms based on discrete cosine transform need some the priori knowledge. To overcome this problem, in this paper, two kinds of blind extraction algorithms using wavelet transform are presented with out prior knowledge. Firstly, this paper proposed an extraction algorithm based on discrete wavelet transform. The low frequency component embedded in the watermarked...
With the development of satellite constellation in various Earth Observation missions, it becomes more and more important to provide remote sensing users with data acquisition request service by using the online system for satellite observation planning. In this paper, the shortcoming of current data acquisition request systems is discussed, and then an online system for satellite observation planning...
This paper analyzes the EGCS in detail and analyzes the disadvantage of multi-objective optimization method according to the feature of EGCS in the basis of general EGCS control rule and multi-objective plan. Multi-objective co-evolutionary algorithm is used EGCS to modeling because the multi-objective optimization method makes the operation speed slow in order to improve service quality and operation...
