In this paper, we define the Banach-valued strong $M_{\alpha}$-integral and study the primitive of the strong $M_{\alpha}$-integral in terms of the $M_{\alpha}$-variational measures. We also prove that every function of bounded variation is a multiplier for the strong $M_{\alpha}$-integral.

The main purpose of this paper is to use the properties of primitive characters, Gauss sums and Ramanujan's sum to study the hybrid mean value of generalized Bernoulli numbers, general Kloosterman sums and Gauss sums, and give two asymptotic formulae.

The primitive orders in a quaternion algebra play a central role of the theory of Hecke operators. In this paper, we study theta series generated by Brandt matrices and its applications to almost Ramanujan graphs.

In this paper we propose two feedfroward unbalance compensation algorithms, they accommodate changes of rotor dynamics including rotating speed. The first one determine the compensating signals by identifying system dynamics successively. Whereas, the second one is more primitive like PID algorithm without identifying system dynamics.

Effects of the changes in bottom topography and non-linearity of the western boundary current on the separation position of the Tsushima Warm Current(TWC) are investigated using a primitive equation model in a simplified model domain which consists of a deep ocean, a continental shelf and a marginal sea(Fig. 1).

Let M be a hyperkahler manifold with the hyperkahler structure (g, I, J, K). In [5], D. Huybrechts suggests that it is an open and interesting question whether any Kahler class that stays Kahler in the twister family can actually be represented by an harmonic Kahler form. In this paper we will consider both this problem and the set of all the primitive harmonic Kahler forms on M.

Cytological characters of ten taxa of the genus Lycoris were investigated to illustrate their chromosomal evolution. The fusion theory was more appropriate than the fission theory. From the viewpoint of the fusion theory L. sanguinea group, diploids with R-shaped chromosomes was the most primitive and they might have diverged into two directions, the diploids with V＋R shaped chromosomes and the triped with V＋R shaped chromosomes via triploids with only R-shaped chromosomes.

본 논문은 한 장의 사진으로부터 선분과 선분의 중점을 이용한 원시기하모델의 3차원 재구성 시스템을 제안한다. 이 시스템은 선분과 중점을 추출할 수 있는 미리 정의된 다면체를 원시기하모델로 사용하며 그 원시기하모델의 각 점을 사용자가 사진에 매핑 시키는 것으로서 3차원 재구성이 수행된다. 미리 정의된 원시기하모델의 사용은 사용자에게 기존의 소실점 입력 방식보다 직관적인 3차원 재구성을 가능하게 한다. 사진에 매핑된 원시기하모델이 포함하고 있는 2차원상의 선분과 선분의 중점으로부터 원시기하모델을 3차인 재구성한다.

동해의 보편적인 순환계를 Lagrangian 부표 수치실험을 통하여 추적하였다. 부표 수치실험을 하기 위하여 사용된 순환장은 동해전반에 관하여 보간된 실제 해저지형을 사용한 원시방정식(Primitive equation)모형으로부터 유도되었다. 시뮬레이션된 순환장은 전반적으로 기존의 관측치와 고찰결과에 일치하지만 좀 더 많은 시간적, 공간적 변화를 보여준다. 부표는 모형영역내에서 동해전역에 걸쳐 해수수송이 최소와 최대가 되는 달인 3월 1일과 9월 1일에 투하되어 각각 1년간 추적되었다. (중략)

Here, we show that the title equation has no positive integer solutions (m, n), where ${\phi}$ is the Euler function.
