Results of the test cases elaborately cover the every combination of BOUs and all the nine inputs of ternary processor. Both the experiment process and results analysis are given in this paper. The experimental results demonstrate that the theory of reconfiguring a TOP is valid and that the reconfiguration circuitry is effective.展开更多

One of its implements is establishing a virtual ente rprise (VE) around the task, where each manufacturing unit, or sub-task, probab ly have at least one resource, or referred to as suppliers. Because each manufac turing unit might be carried out in different geographical places that implies t his probably gives rise to transportation cost, the selection of resources for e ach manufacturing unit must considers not only the manufacturing price of each r esource but also the transfer cost between any two potential resources. This pap er discusses the resource reconfiguration problem with two hypotheses: 1. Permit s one or more resources to attend the same manufacturing unit as long as the tot al cost can reach its least; 2. The freight contains the initial part, that is t he freight concave. Indeed, these hypotheses are much meaningful in the real wor ld. Furthermore, to simplify the solution for this problem, we propose two conce pts: assembly tree (AT) and combinatorial mode base (CMB). Formally an AT is a c omplete production line, which can ensure the parts equilibrium, and its capacit y is subjected to the least capacity of every resources and every path in it. In the end, we propose an implicit enumeration algorithm (IEA) by the use of CMB, including it is a heuristic algorithm for integer programming (HAIP) by the use of AT. The IEA can be outlined that for a determined combinatorial mode, if it h as not enumerated, we use the HAIP to get an near optima and corresponding CMB, marking every combinatorial mode extended from the CMB as enumerated, other cont inue a new iteration. The HAIP can be outlined that for a determined combinatori al mode, there are some determined number of AT, we select an AT with the le ast slope, and select the volume of this AT to its ultimate within its capacity, iterates this doing until the needed volume reached. In the end, we conclude th is paper and prospect the deep research based on GA thought.展开更多

With geometric calculation, this calibration method used the displacement estimation of two thermal microscope images to get the size and direc- tion of each scanning location calibration angle. And each location calibration process was repeated according to the offset given by the system beforehand. The comparison experiments of sequence oversampling reconstruction before and after the micro-scanning location calibration were done. The results showed that the calibration method effectively improved the thermal microscope imaging qual- ity.展开更多

The system employed QuickBird raster imagery displayed on a Trimble Recon X 400 MHz Intel PXA255 Xscale CPU®. The mobile mapping platform was employed to identify specific geographical locations of treated and untreated seasonal An. arabiensis s.s. aquatic larval habitats in Karima rice-village complex in the Mwea Rice Scheme, Kenya. As data pertaining to An. arabiensis s.s. larval habitats were entered, all treated and untreated rice paddies within a 2 km buffer of the agro-village, riceland-complex, epidemiological, study site were viewed and managed on the PDA.展开更多
