Given an image with 2n/spl times/2n pixels, in the TRLE scheme, the image is treated as n/spl times/n blocks and each block has 2/spl times/2 pixels. Since a pixel can be a blank or non-blank pixel, there are 16 templates in a block. To compress an image, the TRLE scheme uses the templates to encode blocks row by row. Blocks in the same row are encoded as a TRLE-sequence. By packing all TRLE-sequences in a packet, the packet is the compressed partial image that can be sent/received among processors. To evaluate the performance of the TRLE scheme, we compare the proposed scheme with the BR, the RLE, and the BRLC schemes. Since a data compression scheme needs to cooperate with some data communication schemes, in the implementation, the binary-swap (BS), the parallel-pipelined (PP), and the rotate-tiling (RT) data communication schemes are used. By combining the four data compression schemes with the three data communication schemes, we have twelve image composition methods. These twelve methods are implemented on a PC cluster The data computation time and the data communication time are measured. The experimental results show that the TRLE data compression scheme with the RT data communication scheme outperforms other eleven image composition methods.","PeriodicalId":376322,"journal":{"name":"First International Symposium on Cyber Worlds, 2002.

In the high-tech era, it is unavoidable that almost all the high-tech products are provided as black-box. For this reason, it, too, is unavoidable that the education in high-tech era will, in stead of extracting the befit of the high-tech stuff, force us to memorize the \"manners\" which were institutionalized by a few high-tech gurus. As basic tools, everybody has to learn word processors, such as Word and Ichitaro, PowerPoint and Excel, and LATEX including tgif. On the other hand, special subjects, such as programming languages, programming language theory, compiler theory, OS theory, DBMS, Internet technology, business models, and software engineering are needed when becoming a software specialist. Mathematics, such as differentiation integral calculus, and physics, such as general dynamics must be also required as liberal arts of software science. The laws related to the patent, copyright, and accountancy for a floatation, and the logical thinking method are the subjects which should be studied as an application subject. In order to prepare the educational environment to study this wide scope of subjects, we must tackle the issues such as restriction of the number of credits and maintenance of lecturer staff. Such issues may be solved by applying less strict criteria when hiring lecturers, reexamining of the whole curriculum, or changing the system of company examination when employing new hires. This paper shows some proposals and remedies applicable to the universities in Japan.","PeriodicalId":376322,"journal":{"name":"First International Symposium on Cyber Worlds, 2002.
