Individual Cloud

It will be thought for sure that any kinds of knowledge will be accumulated and enhanced as Unique Cloud and Smart Cloud. And as a result of this phenomenon, the related space for the world will be able to be indulged in the world of getting processed information as a final use of data for a daily life. This is a very comfortable world to live, but, on the other hand, there might be a possibility which there will be many or some who live only under the offered information and knowledge from intelligent computer systems (Mini Cloud, Unique Cloud, Smart Cloud). So, it is very important to have knowledge of us in investigating whether or not Unique Cloud and Individual Cloud are useful enough to use by inspecting from the outside world even though we are to live in the hypothetical world. And here the authors propose a method to resolve some of the problems under these situations by an idea of “Individual Cloud.”

Unveiling the high-temperature dielectric response of $$\text {Bi}_{0.5}\text {Na}_{0.5}\text {TiO}_{3}$$

Understanding the physics behind changes in dielectric permittivity and mechanical response with temperature and frequency in lead-free ferroic materials is a fundamental key to achieve optimal properties and to guarantee good performance in the technological applications envisaged. In this work, dense $$\text {Bi}_{0.5}\text {Na}_{0.5}\text {TiO}_{3}$$ Bi 0.5 Na 0.5 TiO 3 (BNT) electroceramics were prepared through solid-state reaction of high-grade oxide reagents, followed by sintering at high temperature (1393 K for 3 h). In good agreement with previous reports in the literature, the thermal behaviour of dielectric response from these BNT materials showed the occurrence of a high-temperature diffuse-like permittivity peak, whose origin has been so far controversial. Thermally stimulated depolarization current, impedance and mechanical spectroscopies measurements were here conducted, over a wide range of temperature and frequency, to get a deep insight into the mechanism behind of this event. The approach included considering both as-sintered and reduced BNT samples, from which it is demonstrated that the broad high-temperature dielectric peak originates from interfacial polarization involving oxygen vacancies-related space-charge effects that develop at the grain-to-grain contacts. This mechanism, that contributes to the anomalous behavior observed in the mechanical response at low frequencies, could also be responsible for the presence of ferroelastic domains up to high temperatures.

Efficient Searchable Symmetric Encryption Supporting Dynamic Multikeyword Ranked Search

Searchable symmetric encryption that supports dynamic multikeyword ranked search (SSE-DMKRS) has been intensively studied during recent years. Such a scheme allows data users to dynamically update documents and retrieve the most wanted documents efficiently. Previous schemes suffer from high computational costs since the time and space complexities of these schemes are linear with the size of the dictionary generated from the dataset. In this paper, by utilizing a shallow neural network model called “Word2vec” together with a balanced binary tree structure, we propose a highly efficient SSE-DMKRS scheme. The “Word2vec” tool can effectively convert the documents and queries into a group of vectors whose dimensions are much smaller than the size of the dictionary. As a result, we can significantly reduce the related space and time cost. Moreover, with the use of the tree-based index, our scheme can achieve a sublinear search time and support dynamic operations like insertion and deletion. Both theoretical and experimental analyses demonstrate that the efficiency of our scheme surpasses any other schemes of the same kind, so that it has a wide application prospect in the real world.

Stability of Galerkin discretizations of a mixed space–time variational formulation of parabolic evolution equations

We analyze Galerkin discretizations of a new well-posed mixed space–time variational formulation of parabolic partial differential equations. For suitable pairs of finite element trial spaces, the resulting Galerkin operators are shown to be uniformly stable. The method is compared to two related space–time discretization methods introduced by Andreev (2013, Stability of sparse space-time finite element discretizations of linear parabolic evolution equations. IMA J. Numer. Anal., 33, 242–260) and by Steinbach (2015, Space-time finite element methods for parabolic problems. Comput. Methods Appl. Math., 15, 551–566).

“Natural Work” as Self-capability

A great wandering humanist philosopher, enlightener and outstanding poet Grigory Savvich Skovoroda’s work pertains to a difficult period in the life of the 18th century Eastern Ukraine. Against the background of growing injustice and evil, the decline of spiritual values, an authentic practical philosophy of individual opposition to a self-serving world steeped in vice was born. Skovoroda’s philosophy completely lacks the intention to consider proprietary interests as the driving force of human development. Its key principle of human development is self-examination within one’s own energy-activity-object-related space. The call for self-examination from the perspective of the authentic idea of “natural work” is revealed dynamically as the process of bringing the objective world into harmony with the nature of an individual. “Natural work” is a process of individual’s constant creative self-overcoming on the ascent to subject identity; total communion of man with the universal whole.

Why Factory1: The Spatial Significance of Architectural Education Buildings

The educational space of the Architecture faculty is used to cultivate architects. At the same time, it becomes the carrier of architectural ideas and teaching methods. The type of architecture and its spatial organization reflect the architectural education philosophy and attitude. Back in history, as early as the Renaissance, there had study places for architects emerged. After the industrial revolution and the modernist process, the types of architectural education sites are more diverse, and their main features are the spatial form of hybrid and box-in-box. This article preliminarily analyzes the evolution of the outline of architectural education building and interprets the spatial ideas in each period. The study focuses on the famous Dutch architectural school–BKCity of the Delft University of Technology, analyzing the teaching space logic of its distinctive Why Factory and exploring how the related space could stimulate the vitality of architectural education. By the analogy of some architectural schools, it also tries to compare the differences and characteristics of Chinese and Western architectural academies, finding out the spatial significance in architecture discipline, education method as well as sustainable application.

A pair of kinematically related space curves

We investigate the relation between two types of space curves, the Mannheim curves and constant-pitch curves and primarily explicate a method of deriving Mannheim curves and constant-pitch curves from each other by means of a suitable deformation of a space curve. We define a “radius” function and a “pitch” function for any arbitrary regular space curve and use these to characterize the two classes of curves. A few non-trivial examples of both Mannheim and constant pitch curves are discussed. The geometric nature of Mannheim curves is established by using the notion of osculating helices. The Frenet–Serret motion of a rigid body in theoretical kinematics is studied for the special case of a Mannheim curve and the axodes in this case are deduced. In particular, we show that the fixed axode is developable if and only if the motion trajectory is a Mannheim curve.

Measuring Transit Oriented Development of Existing Urban Areas around Metro Stations in Faridabad City

Urban population in Indian cities is encouraging auto reliance and having unsafe economic, social and environmental consequences. Land-use-change patterns are the outcome of the complex relations between the human and the physical surroundings. To address these issues the planners are moving beyond land use planning to a sustainable development. Transit and Land use planning are important components to achieve sustainable future of urban development. TOD is a planning tool to encourage this integration. This paper discusses the land use scenario and opportunity around four Metro transit stations in Faridabad city. Different methods and various sets of indicators are considered to evaluate and measure TOD index in this study. This study will evaluate and measure the Faridabad city in the context of land use around Metro Stations to support TOD. This paper seeks to answer how to promote walkable communities, compact and transit-oriented development (TOD) that incorporates mixed land use development, including neighbourhood schools, retail and business-related space and a mix range of housing types within walkable distance. This paper concludes that the stations area which had a low TOD score needs to have policy for improvement. If planned efficiently, TODs can realize the sustainable development with considerable change in the urban development that focuses on pedestrian based neighbourhood planning.

Time and Space of Heritage Preservation: Conservation Theoretical Perspective

In this article, I discuss the categories of time and space in lightof heritage conservation. I demonstrate that heritage creation isthe simultaneous creation of human time and space and that thecritical treatment of heritage requires a more specific analysis ofthese terms. First, I look at how the creation of human space occursthrough objects, and how the objects of the physical environmentbecome things, i.e. parts of our living world. The world can only beunderstood through change. This is a fundamental finding that formsthe basis for both elementary senses and complicated philosophies.In order to explain the change in heritage-related space, I am usingthe terms artificialisation and heritage technology. Artificialisationmeans the anthropogenic transformation of the environment,which takes place mainly with the help of technological systems.Therefore, the environment encompasses physical, biological andgenetic environments, as well as the human culture with its past.In this environment, it is impossible to distinguish between thehuman and non-human, since they make up a single hybrid whole.Artificialisation is by no means a determined course in history; it isa human means of description, a metaphor that helps to explain theprocesses ongoing in nature and human society. According to thisapproach, the heritage process is one technique in the artificialisationof the environment.Although change is central to conservation theory, it is also aconcept that causes the greatest doubts and ambiguous interpretations.The reason for this is very simple: change is related to time, whichis a foundational concept. In this article, I use metaphysical timemodels to analyse the life course of things and their damage. Finally,I also refer to the conservation theories of Eugène Viollet-le-Ducand John Ruskin. The essential difference between the conservationtheories that are discussed here lies in their attitudes toward time,and the related problems of object authenticity and identity. In theframework of the presentist model, it is not possible to solve themain contradiction connected to restoration. Stylistic restorationruins the authenticity of buildings as historical documents; howeverwithout restoration, the objects would be destroyed and therebylose their historical value. However, a solution to this dilemma canbe found based on the eternalist time model, which helps connectheritage to contemporary time, and avoid its physical, legal, andmental separation from the everyday life of society. The fact thatincluding objects as a part of heritage may damage them instead ofpreserving them should not be overlooked. The authenticity of anobject is not related to any ideal state in its history but to a conceptual,factual and actual state in its wholeness.
