We consider the simple antisymmetrized algebra $N(e^{A_P},n,t)_1^-$. The simple non-associative algebra and its simple subalgebras are defined in the papers [1], [3], [4], [5], [6], [8], [13]. Some authors found all the derivations of an associative algebra, a Lie algebra, and a non-associative algebra in their papers [2], [3], [5], [7], [9], [10], [13], [15], [16]. We find all the derivations of the Lie subalgebra $N(e^{{\pm}x_1x_2x_3},0,3)_{[1]}{^-}$ of $N(e^{A_p},n,t)_k{^-}$ in this paper.

분산된 환경에서의 정보의 효율적인 사용을 위하여 이를 체계적으로 구축할 필요가 발생하였으며 더욱이 현재 공개키 기반구조에 대한 필요성이 증대되고 공개키 관리가 중요 문제고 다루어지고 있다. 이를 위한 한가지 방법으로 대렉토리가 제안되었고, 이는 현재 ISO/IEC 9594시리즈로 표준화되었다. 본 고에서는 디렉토리의 개념과, 정보의 구성방식 및 지원 서비스에 대하여 고찰하였다.

In this paper, we calculate the number of points on elliptic curves $y^2=x^3+Ax$ over $F_{p^r}$ modulo 24. This is a generalization of [8], [9] and [16].

The relationships involving acid-consuming capacity and X-ray powder diffraction patterns of aluminum hydroxide gel were studied. The aging of antacid efficacy of aluminum hydroxide gel has also been characterized by using X-ray powder diffraction. The acid-consuming capacity decreased with progress of crystallization from amorphous alumino gel, and it was found that aged product at 80.deg. C had crystal structure of bohmite (.alpha.-Al.sub 2/O$_{2}$(OH)$_{2}$). It was also noted that the rate of aging decreased with decreasing pH of aluminum hydroxide gel.

PS2 기반 게임 SOE(State Of Emergency)가 성공을 거두자 이 게임의 개발업체인 미국 VIS엔터테이먼트사는 이를 X-box에서도 게임이 가능하도록 변환시키기로 결정했다. 이는 SOE의 성공을 보다 오랫동안 누리기 위한 방안이었다. 시간은 충분했다. PS2와의 계약기간이 8개월이나 남아 있었기에 그 이전에 SOE의 X-box버전을 개발해야할 필요성은 없었다. 문제는 수작업으로 조정된 모든 코드를 수정해야 한다는 점이었다. SOE의 사례를 바탕으로 새로운 미션에 대한 해결법을 찾아보자.

Microwave absorbers for X-Band RADAR have been designed and fabricated trialy both in sheet and paint types, as a result of which the relative bandwidth of nearly 8% in both cases has been obtained under the tolerance limits of the reflection coefficients lower than -20dB. The matching thickness becomes 1.36 to 1.56mm which is significantly thinner than that of the conventional ones. Furthermore, it was shown that the microwave absorbing characteristics vary in accordance with the density and the mixing ratios of the materials constituting absorbs.

Template condensation of ${\alpha}$-diketones such as 2,3-butanedione or benzil with diaminoalkanes such as 1,2-diaminoethane, 1,3-diaminopropane, 1,4-diaminobutane, 1,6-diaminohexane, 1,8-diaminooctane or 1,12-diaminododecane in the presence of Cr(III) results in the formation of complexes of the type $[CrI,X_2]X$ (where L = tetraazamacrocycle having 12 to 32-membered ring and $X={NO_3}^- or Cl^-).$ The complexes have been characterized by elemental analyses, magnetic measurements and IR and diffuse reflectance spectra.

In this paper, we present a multi-core processor including multimedia specific instructions to process multimedia data efficiently in the mobile environment. Multimedia specific instructions exploit subword level parallelism (SLP), while the multi-core processor exploits data level parallelism (DLP). These combined parallelisms improve the performance of multimedia processing applications. The proposed multi-core processor including multimedia specific instructions is implemented and tested using a Xilinx ISE 10.1 tool and SoCMaster3 testbed system including Vertex 4 FPGA. Experimental results using a fire detection algorithm show that multimedia specific instructions outperform baseline instructions in the same multi-core architecture in terms of performance (1.2x better), energy efficiency (1.37x better), and area efficiency (1.23x better).

In this paper, we implemented and evaluated the performance of a vector-based rasterization algorithm of 3D graphics using a SIMD-based many-core processor that consists of 4,096 processing elements. In addition, we compared the performance and efficiency of the rasterization algorithm using the many-core processor and commercial GPU (Graphics Processing Unit) system which consists of 7 GPUs and each of which have 512 cores. Experimental results showed that the SIMD-based many-core processor outperforms the commercial GPU system in terms of execution time (3.13x speedup), energy efficiency (17.5x better), and area efficiency (13.3x better). These results demonstrate that the SIMD-based many-core processor has potential as an embedded mobile processor.
