The estimation and forecast of solar energy yield with Weibull distribution

In the first and second chapter the article provides an overview of the currently used energy sources in Hungary and the most popular renewable energies. In addition, the Weibull estimation is presented, too. The subsequent chapter looks at some of the research results about the solar energy optimization with Weibull distribution. The study presented is a mathematical solution of the solar energy optimization with distribution. The final chapter contains a brief explanation of the results. This publication briefly summarizes a prototype solution for an estimation and forecast of solar energy and yield with Weibull distribution.

The Whitehead Decomposition

‘The Whitehead Decomposition’ introduces this historically significant decomposition. Not only is the quotient of the 3-sphere by the Whitehead decomposition not homeomorphic to the 3-sphere, it is not even a manifold. In order to detect this curious fact, the notion of a noncompact space being simply connected at infinity is introduced. The chapter also describes the Whitehead manifold, which is a contractible 3-manifold not homeomorphic to Euclidean space. While the Whitehead decomposition does not shrink, its product with the real line does, as is proved in this chapter; in other words, the quotient of the 3-sphere by the Whitehead decomposition is a manifold factor. The proof of the disc embedding theorem utilizes Bing–Whitehead decompositions, which may be understood to be a mix between the Whitehead decomposition and the Bing decomposition from a previous chapter. In a subsequent chapter, precisely when Bing–Whitehead decompositions shrink is explained.

Replicable Rooms and Boundary Shrinkable Skyscrapers

‘Replicable Rooms and Boundary Shrinkable Skyscrapers’ points out precisely which properties of skyscrapers are required in the remainder of the proof of the disc embedding theorem. To achieve this, it introduces an abstraction of towers, known as buildings. The required properties for a generalized skyscraper include boundary shrinkability and replicability. The former allows the conclusion that the vertical boundary of a generalized skyscraper is a solid torus. Replicability ensures that any generalized skyscraper contains uncountably many other skyscrapers as subsets. Both of the above properties will be essential in the construction of the design in a subsequent chapter.

Information Technology and Democracy. Chances and Challenges

We live in the time of profound transformations commonly labelled with the word “globalization”. The rise of one ecological-technological-social system encompassing our whole planet is an important element of these processes. Solving big global problems demands knowledge of two complementary sorts: on the one hand – going “in depth”, on the other – going “in breadth”. The present paper assumes the second (in a sense: philosophical) perspective. It tries to analyze some relations between the development of technology (IT) and the development of democracy. The notion of democracy, its various forms and axiological reasons for it are considered first. In the subsequent chapter different consequences (both positive and negative) the IT development has for contemporary democracy are discussed. In the next chapter the evolutionary nature of the technological development is debated as well as the question of (democratic) control of this process. The development of Artificial General Intelligence is presented as a challenge for democracy

Methods and Technologies for Mastering Uncertainty

Uncertainty affects all phases of the product life cycle of technical systems, from design and production to their usage, even beyond the phase boundaries. Its identification, analysis and representation are discussed in the previous chapter. Based on the gained knowledge, our specific approach on mastering uncertainty can be applied. These approaches follow common strategies that are described in the subsequent chapter, but require individual methods and technologies. In this chapter, first legal and technical aspects for mastering uncertainty are discussed. Then, techniques for product design of technical systems under uncertainty are presented. The propagation of uncertainty is analysed for particular examples of process chains. Finally, semi-active and active technical systems and their relation to uncertainty are discussed.

Financial Instability

In this chapter, the central bank is put aside and we review simple models of financial instability, which will be the basis for the subsequent chapter to explain the role of the central bank as lender of last resort. We first recall that financial instability is mostly triggered by a negative shock on asset prices, and thereby on the solvency of debtors, which in turn worsens access to credit and can set in motion a liquidity crisis with vicious circles. We develop the concepts of solvency “conditional” and “unconditional” on liquidity: a decline in asset prices can lead an unconditionally solvent debtor to become only conditionally solvent, such that sufficient liquidity becomes decisive for preventing its default. We then apply these concepts to the stability of bank funding and introduce the problem of bank runs. We subsequently show why asset liquidity in a dealer market deteriorates during a financial crisis (increased volatility and uncertainty increase the required bid-ask spread); how asymmetric information can lead to a freeze of credit markets in a simple adverse selection model; how declining and more volatile asset prices drive increases of haircut, and how these can force fire sales and defaults of borrowers. We finally discuss the interaction between these various crisis channels.

Proaktívna činnosť požiarnej ochrany pre mäkké ciele

The article deals with proactive ways of fire protection of soft target objects. The first chapter deals with the general characteristics and description of a soft target object. The next chapter focuses on the characteristics and description of a proactive security breach model. The article then characterizes the analysis of fire protection measures. The subsequent chapter deals with proactive methods of fire protection, where the operation of activities in fire protection is divided into several phases. The final chapter focuses on the design and application of specific proactive methods of providing fire protection for a soft target object. Specifically, it is a shopping centre building, where several types of proactive activities are proposed to improve the effectiveness of minimizing the risk of threats in fire protection.

Pictures, Communication, and Meaning

This chapter provides an overview of the project. Pictures are used for communication, and the way they do this sheds light on their syntax, semantics, and pragmatics. Pictures can have attributive and singular contents in many different ways. All of these pictorial meanings are built on a foundation of pictorial character and pictorial content. Unpacking these various meanings constitutes the meaning thread of the book, which is most prominent in Chapters 2, 4, 5, and 6. In addition, it is impossible to understand the communicative uses to which pictures are put without understanding how pictures have meaningful parts, the focus of Chapters 3, 7, and 8. This chapter sketches both the meaning thread and the parts thread as a way of helping keep the whole project in view, while each subsequent chapter winds up being focused on a specific aspect of it.

The Analysis of the Possibility to Construct Optimal Third-degree Reference Graphs

The subject of this article is to present the results of the analysis of the possibilities to create optimal third-degree Reference Graphs which may be used to model ICT networks. The first part discusses the causes for the interest in the subject of the thesis. Basic definitions and terms related to the analysed type of graphs describing ICT networks are given. The second part consists of the analysis of the possibilities to construct regular third-degree structures bases on the usage of one ring of the parameters typical for Reference Graphs. A method of conduct is presented and then used for checking the potential possibility to construct optimal graphs. In the subsequent chapter the results of analysis of the possibilities to create optimal third-degree graphs with a double ring is discussed. The paper is concluded by observations and conclusions resulting from the research.

Introduction

Opening with an account of the 1878 murder in Rome that gave rise to the trial on which the book is based, the introduction presents the key figures of a local emotional drama replayed on a national stage. It contextualizes these figures’ stories within Italy’s recent history, and outlines their geographical origins in the newly unified peninsula. Viewing the episodes of social life revealed by the criminal investigation through an emotions-history lens, the introduction surveys the analytical tools currently available for historians of emotion—such as regimes, communities, and practices—then proposes a new paradigm that conveys a stronger sense of boundaries and human scale: the ‘emotional arena’. These are the social spaces that can be seen to have influence over both the experience and expression of emotions—whether bedrooms, theatres and churches, or legal courtrooms. The introduction then lays out the book’s structure, outlining the way each subsequent chapter explores an example of such an emotional arena. These are the marital home, a nomadic circus based on an extended family, the imaginary arenas created by writers of secret love letters, arenas of grief and mourning, forensic investigations of death, plans for a murder, and finally, the courtroom in Rome where the story culminated.
