In this paper, we have presented rough ideal statistical convergence of sequence on neutrosophic normed spaces as a significant convergence criterion. As neutrosophication can handle partially dependent components, partially independent components and even independent components involved in real-world problems. By examining some properties related to rough ideal convergence in these spaces we have established some equivalent conditions on the set of ideal statistical limit points for rough ideal statistically convergent sequences.

Children of three-to-eighteen-years-old have been brought up in the institution (Orphanage) for several reasons such as family dissolution, divorce and poverty since the Korean Was of 1950. The Cottage, where these children are housed and brought up has dining room, library and bedrooms, plays as a significant social interaction place as well as study. Since the most facilities were built during the 1950-1960s period, most of the cottages are now in the condition of being rebuilt or remodelled. Because living space and studying space are mixed, it will be necessary to provide another studying space separated from living space. And then it will be also necessary to provide a space for play or rest between the two spaces. This study was conducted to obtain some basic data necessary for design of spaces in the orphanages by examining the relations between the studying activities of children and residence types.

In this paper, the Artificial Intelligence Space(AI-Space) for human-robot interface is presented, which can enable human-computer interfacing, networked camera conferencing, industrial monitoring, service and training applications. We present a method for representing, tracking, and objects(human, robot, chair) following by fusing distributed multiple vision systems in AI-Space. The article presents the integration of color distributions into particle filtering. Particle filters provide a robust tracking framework under ambiguous conditions. We propose to track the moving objects(human, robot, chair) by generating hypotheses not in the image plane but on the top-view reconstruction of the scene.

The convergence of ICT and cloud computing is treated as a main issue all over the fields including education. This development leads to change from e-learning to u-learning and smart education. Therefore, we need to study in term of the systematic and a long-term viewpoint how smart education environment have an influence on the practical space. And we need a concrete study for smart education space based on property of space. Under these critical mind, this study understands the smart education space in terms of the convergence of computing space and physical space. As a Result, smart education space have major property such as flexibility, communication, polyvalence.

There is growing tendency to find rest in one's own space for senses of isolation and loneliness were felt as excluded from the contemporary society. It is necessary for a private space to be reproduced as a place of consolation and cure beyond rest. This study is dealing with project research works, which are exhibited in 2014 Home Table Deco Fair with the theme of for individual rest and consolation. This study, based on the investigation of Korean lifestyle and trend, considered design, in the living space of modern people with Korean-style design, and in the perspective of color, quality of material, and aesthetic sense, and suggests that design convergence of the east and the west. This study can contribute to recreate meaning and principles of design based on Korean aesthetics and culture according to the needs of the present age.

According to the enforcement of various laws for the ubiquitous city, the convergence technologies for the ubiquitous in the industry has been emerging. In this paper, we propose a method for the ubiquitous convergence technology by a functional integration of the public employment of the physical space and physical facilities, as the related laws are enforced and the city development plan is processed in the situation which constructs the ubiquitous and eco-city. We also present a scheme for the establishment to prepare the foundation of systematization, standardization, and information-oriented by providing an application example for the common-use-channel and unification IP pool based on the proposed method.

Let K be a nonempty convex subset of an arbitrary Banach space X and $T\;:\;K\;{\rightarrow}\;K$ be a uniformly continuous strictly hemi-contractive operator with bounded range. We prove that certain Ishikawa iteration scheme with errors both converges strongly to a unique fixed point of T and is almost T-stable on K. We also establish similar convergence and almost stability results for strictly hemi-contractive operator $T\;:\;K\;{\rightarrow}\;K$, where K is a nonempty convex subset of arbitrary uniformly smooth Banach space X. The convergence results presented in this paper extend, improve and unify the corresponding results in Chang [1], Chang, Cho, Lee & Kang [2], Chidume [3, 4, 5, 6, 7, 8], Chidume & Osilike [9, 10, 11, 12], Liu [19], Schu [25], Tan & Xu [26], Xu [28], Zhou [29], Zhou & Jia [30] and others.

In this article, we first give metric version of an iteration scheme of Agarwal et al. [1] and approximate fixed points of two finite families of nonexpansive mappings in hyperbolic spaces through this iteration scheme which is independent of but faster than Mann and Ishikawa scheme. Also we consider case of three finite families of nonexpansive mappings. But, we need an extra condition to get convergence. Our convergence theorems generalize and refine many know results in the current literature.

The temperature preconditioning is applied to the Navier-Stokes equations. Also, a new concept of diffusion Mach numbers is introduced to modify the reference Mach number for the Navier-Stokes equations. Flows over a circular cylinder were calculated at different Reynolds numbers. It is shown that the temperature preconditioning improves the convergence characteristics of Navier-Stokes equations. Also, it is shown that the modified reference Mach number alleviates the convergence problems at locally low speed regions.

A temperature preconditioning that modulates the derivative of density with respect to temperature is proposed to improve the convergence characteristics of the preconditioned Euler equations. Flows in a two-dimensional channel with a 10% circular bump in the middle of the channel were calculated at different speeds. The numerical dissipation terms of the Roe’s FDS scheme according to the temperature preconditioning are derived. It is shown that the temperature preconditioning accelerates convergence of the preconditioned Euler equations.
