Image-based rendering is an approach to generate realistic images in real-time without modeling explicit 3D geometry, Especially, TIP(Tour Into the Picture) is preferred for its simplicity in constructing 3D background scene. However, TP has a limitation that a viewpoint cannot go far from the origin of the TIP for the lack of geometrical information. in this paper, we propose a method to interpolating the TIP images to generate smooth and realistic navigation. We construct multiple TIP models in a wide area of the virtual environment. Then we interpolate foreground objects and background object respectively to generate smooth navigation results.

This is an interior design for a furniture & lighting design exhibition. The concept of design is to secure the smooth flow planning of an audience and effective direction of an exhibit Design content include 1) installation(passage of light) to guide an audience from entrance to right side of the exhibition space to prohibit the flow dispersion and keep smooth continual circulation flow plan 2)image-wall to introduce exhibition 3)installation to help the global understanding of exhibit 4)exhibition stand design considering proper height of audience's eye.

This paper proposes a method for producing smooth and positive estimates of the intensity function of an inhomogeneous Poisson process based on the shrinkage of wavelet coefficients of the observed counts. The information projection is used in conjunction with the level-dependent thresholds to yield smooth and positive estimates. This work is motivated by and demonstrated within the context of a problem involving gamma-ray burst data in astronomy. Simulation results are also presented in order to show the performance of the information projection estimators.

In this paper we propose a smooth nonparametric estimator of mean residual life based on a complete sample. This estimator is constructed using the maximum likelihood estimate of cumulative failure rate in the class of distributions which have piecewise linear failure rate functions between each pair of observations. We derive the asymptotic properties of our estimator. Examples using simulated data are used to illustrate the performance of this estimation.

서로 다른 그루브 깊이를 갖는 circumferentially-grooved 씨일들의 동특성 계수 및 누설량에 대한 실험결과를 분석하였다. 실험된 결과를 분석해 보면, 그루브 깊이가 증가함에 따라, 누설량이 서서히 증가함을 알수 있다. Smooth 씨일 및 damper 씨일과 비교할때, smooth 씨일은 최대의 direct stiffness를 가지며, 평균 씨일 간극의 증가함에 따라 direct stiffness가 감소한다. Effective damping에 있어서, circumferentially-grooved 씨일은 최소의 값을 가지는 반면, 누설량은 가장 적다. 이론과의 실험치 비교는 일반적으로 만족할만한 결과를 보인다.

Let E be a smooth Banach space. Suppose T : E longrightarrow E is a strongly accretive map. It is proved that each of the two well known fixed point iteration methods (the Mann and Ishikawa iteration methods), under suitable conditions, converges strongly to a solution of the equation Tx = f.

Subendothelial accumulation of foam cells plays a key role in the initiation of atherosclerosis. These foam cells accumulate in fatty streaks that evolve to more complex fibrofatty or atheromatous plaques. Oxidized LDL may also be involved in atherogenesis by inducing smooth muscle cell proliferation and smooth muscle foam cell generation. (omitted)

We construct new families of smooth Fano fourfolds with Picard rank 1 which contain open 𝔸¹-cylinders, that is, Zariski open subsets of the form Z × 𝔸¹, where Z is a quasiprojective variety. In particular, we show that every Mukai fourfold of genus 8 is cylindrical and there exists a family of cylindrical Gushel-Mukai fourfolds.

In this paper, we introduce the notion of toric special weak Fano manifolds, which have only special primitive crepant contractions. We study their structure, and in particular completely classify smooth toric special weak Fano 4-folds. As a result, we can confirm that almost every smooth toric special weak Fano 4-fold is a weakened Fano manifold, that is, a weak Fano manifold which can be deformed to a Fano manifold.

In the previous paper [4], we classified the Weierstrass semigroups at a pair of inflection points of multiplicities d and d - 1 on a smooth plane curve of degree d. In this paper, as a continuation of those results, we classify all semigroups each of which arises as a Weierstrass semigroup at a pair of inflection points of multiplicities d, d - 1 and d - 2 on a smooth plane curve of degree d.
