Affine Arithmetic-Based Methods for Uncertain Power System Analysis
Affine Arithmetic-Based Methods for Uncertain Power System Analysis presents the unique properties and representative applications of Affine Arithmetic in power systems analysis, particularly as they are deployed for reliability optimization.The work provides a comprehensive foundation in Affine Arithmetic necessary to understand the central computing paradigms that can be adopted for uncertain power flow and optimal power flow analyses.These paradigms are adapted and applied to case studies, which integrate benchmark test systems and full step-by-step procedure for implementation so that readers are able to replicate and modify.The work is presented with illustrative numerical examples and MATLAB computations.

Piecewise Affine Control : Continuous-Time, Sampled-Data, and Networked Systems
Engineering systems operate through actuators, most of which will exhibit phenomena such as saturation or zones of no operation, commonly known as dead zones.These are examples of piecewise-affine characteristics, and they can have a considerable impact on the stability and performance of engineering systems.This book targets controller design for piecewise affine systems, fulfilling both stability and performance requirements. The authors present a unified computational methodology for the analysis and synthesis of piecewise affine controllers, taking an approach that is capable of handling sliding modes, sampled-data, and networked systems.They introduce algorithms that will be applicable to nonlinear systems approximated by piecewise affine systems, and they feature several examples from areas such as switching electronic circuits, autonomous vehicles, neural networks, and aerospace applications. Piecewise Affine Control: Continuous-Time, Sampled-Data, and Networked Systems is intended for graduate students, advanced senior undergraduate students, and researchers in academia and industry.It is also appropriate for engineers working on applications where switched linear and affine models are important.

What is affine independence?
Affine independence refers to a set of points in a vector space that are not collinear, meaning they do not lie on the same straight line. In other words, the points are not linearly dependent, and there is no way to express one of the points as a linear combination of the others. Affine independence is important in various mathematical and geometric contexts, such as in linear algebra, optimization, and computer graphics.
-
What are affine subspaces?
Affine subspaces are sets of points in a vector space that are closed under affine combinations. An affine combination of points is a weighted sum of the points where the weights sum to 1. Affine subspaces can be thought of as generalizations of lines, planes, and hyperplanes in higher dimensions. They can be represented as translations of linear subspaces, and they are characterized by the property that any two points in the subspace determine a unique line contained in the subspace.

What is an affine subject?
An affine subject refers to a person who is emotionally invested in a particular topic or issue. This emotional investment can lead the person to have a biased or subjective perspective on the matter. Affine subjects may have personal experiences, beliefs, or values that strongly influence their views and opinions on the topic, making it difficult for them to remain completely objective. It is important to recognize and consider the influence of affine subjects when evaluating their perspectives on a given subject.

What is the main theorem of affine geometry?
The main theorem of affine geometry states that given a set of points and a set of vectors in a vector space, there exists a unique affine space such that the points correspond to the origin of the space and the vectors correspond to the translations of the space. This theorem forms the foundation of affine geometry, which studies the properties of affine spaces and their transformations without considering the concept of distance or angles. It provides a framework for understanding the geometric properties of objects that remain unchanged under translation, rotation, and scaling.

Is the goddess Selene Artemis?
No, the goddess Selene is not Artemis. In Greek mythology, Selene is the goddess of the moon, while Artemis is the goddess of the hunt, wilderness, and childbirth. Although they are both associated with the night and the moon, they are distinct deities with their own unique attributes and roles in mythology. Selene is often depicted as driving a chariot across the night sky, while Artemis is known for her skill in hunting and her association with wild animals.

What is an affine subspace and what is a spanned subspace?
An affine subspace is a subset of a vector space that is obtained by translating a subspace by a fixed vector. It is a flat geometric object that does not necessarily pass through the origin. On the other hand, a spanned subspace is a subspace that is formed by taking linear combinations of a set of vectors. It is the smallest subspace that contains all the vectors in the set.

What is the difference between similarity transformation and affine transformation in geometry?
In geometry, a similarity transformation preserves the shape of a figure while changing its size. This transformation involves scaling, rotating, and reflecting the figure. On the other hand, an affine transformation includes not only scaling, rotating, and reflecting, but also translations. Affine transformations preserve parallel lines and ratios of distances between points, but they do not necessarily preserve angles or shapes.

What disadvantage does the Caesar encryption have compared to the general definition of affine ciphers?
The disadvantage of the Caesar encryption compared to the general definition of affine ciphers is that it is a special case of the affine cipher with a limited set of possible keys. In the Caesar encryption, the key is limited to a single number representing the shift value, while the general affine cipher allows for a wider range of possible keys, including both a multiplicative and additive component. This limitation makes the Caesar encryption more vulnerable to brute force attacks, as there are only 25 possible keys to try compared to the larger key space of the general affine cipher.
