GSIS 자료기반부 설계를 위한 ACAD-SYSTEM의 활용방안에 관한 연구
박운용,이대명,차성렬 동아대학교 공과대학 부설 한국자원개발연구소 1994 硏究報告 Vol.18 No.1
GSIS is a system that contains spatially referenced data that can be analyzed and converted to information for a specific set of purpose,or application. The key of feature of a GSIS is the analysis of data produce new information. The history of using computers for mapping and spatial analysis shows that there have been paralled developments in automated data capture, data analysis, and presentation in several broadly related fields. Geo-spatial information systems do have a lot in common with auto computer aided drafting(ACAD) systems used for drafting a wide range of technical objects. This study aims to convert of GSIS database model by ACAD system.
A Remark Of P(i,k) On Elliptic Curves And Application For Manchester Coding
( Dae Yeoul Kim ),( Min Soo Kim ) 호남수학회 2011 호남수학학술지 Vol.33 No.2
Greg([Greg]) considered that N(k)=(k)∑(i=1)(-1)(i+1)(P(i,k))(P)N1, Where the P(i,k)`s were polynomials with possitive integer coefficients.In this paper, we will give the equations for ∑P(i,k) modulo 3. Usingthis, if we send a information for elliptic curve to sender, we canmake a new checksum method for Manchester coding in IEEE 802.3or IEEE 802.4.
ON THE CONVOLUTION SUMS OF CERTAIN RESTRICTED DIVISOR FUNCTIONS
( Dae Yeoul Kim ),( Aeran Kim ),( Sankaranarayanan ),( Ayyadurai ) 호남수학회 2013 호남수학학술지 Vol.35 No.2
We study convolution sums of certain restricted divisor functions in detail and present explicit evaluations in terms of usual divisor functions for some specific situations.
Convolution Sum ∑(m<n/8)/σ1(2m)σ1(n-8m)
( Dae Yeoul Kim ),( Ae Ran Kim ),( Hwa Sin Park ) 호남수학회 2012 호남수학학술지 Vol.34 No.1
In this paper, we present the convolution sum ∑(m<n/8)/ σ1(2m)σ1(n-8m) evaluated for all n □ N.
Combinatoric Convolution Sums Containing σ and ð of the Form 2m p
( Dae Yeoul Kim ),( Joong Soo Park ) 호남수학회 2014 호남수학학술지 Vol.36 No.3
In this paper, we study combinatoric convolution sums of divisor functions and get values of this sum when n=2m p. We find that the value of this convolution sum is represented by a sum of powers of 2 and Bernoulli or Euler number.
A REMARK OF EISENSTEIN SERIES AND THETA SERIES
Kim, Dae-Yeoul,Koo, Ja-Kyung Korean Mathematical Society 2002 대한수학회보 Vol.39 No.2
As a by-product of [5], we produce algebraic integers of certain values of quotients of Eisenstein series. And we consider the relation of $\Theta_3(0,\tau)$ and $\Theta_3(0,\tau^n)$. That is,we show that $$\mid$\Theta_3(0,\tau^n)$\mid$=$\mid$\Theta_3(0,\tau)$\mid$,\bigtriangleup(0,\tau)=\bigtriangleup(0,\tau^n)$ and $J(\tau)=J(\tau^n)$ for some $\tau\in\eta$.
INTEGRABILITY AS VALUES OF CUSP FORMS IN IMAGINARY QUADRATIC
Kim, Dae-Yeoul,Koo, Ja-Kyung Korean Mathematical Society 2001 대한수학회논문집 Vol.16 No.4
Let η be the complex upper half plane, let h($\tau$) be a cusp form, and let $\tau$ be an imaginary quadratic in η. If h($\tau$)$\in$$\Omega$( $g_{2}$($\tau$)$^{m}$ $g_{3}$ ($\tau$)$^{ι}$with $\Omega$the field of algebraic numbers and m. l positive integers, then we show that h($\tau$) is integral over the ring Q[h/$\tau$/n/)…h($\tau$+n-1/n)] (No Abstract.see full/text)
KIM, DAE-YEOUL,KOO, JA-KYUNG,KIM, MYUNG-HWAN Korean Mathematical Society 2005 대한수학회논문집 Vol.20 No.3
Let p and q be odd primes with p=2q+1. We study the number of solutions of congruence equations $ax^i\;+\;by^j\;{\equiv}\;c$ (mod p) and a$ax^i\;+\;by^j\;+\;dz^t\;{\equiv}\;c(modp)$
