Minkowski-type and Alexandrov-type theorems for polyhedral herissons

Classical H.Minkowski theorems on existence and uniqueness of convex polyhedra with prescribed directions and areas of faces as well as the well-known generalization of H.Minkowski uniqueness theorem due to A.D.Alexandrov are extended to a class of nonconvex polyhedra which are called polyhedral herissons and may be described as polyhedra with injective spherical image.Comment: 19 pages, 8 figures, LaTeX 2.0

Fighting Words: Applications in Modern Racial Contexts

The notion of “fighting words” was established in the benchmark case Chaplinsky v. New Hampshire, which chronicled how Chaplinsky, a proselytizing Jehovah’s witness, called the city marshal a “God damned racketeer” and a “damned fascist,” and was convicted for violating a state statute forbidding individuals from addressing others in an offensive way. The New Hampshire statute and the Chaplinsky ruling established a new framework for classifying speech as fighting words, which are not constitutionally protected speech. For speech to be considered fighting words, it must satisfy three criteria: The speech must be individually addressed and incite immediate violence in an average addressee. This essay explores the fighting words doctrine as presently constructed, determines that the criterion regarding an “average addressee” is particularly problematic, and suggests that the doctrine be altered to include specific demographics such as race. First, opposing viewpoints in favor of the current doctrine, including maintaining a high level of protection of free speech and avoiding issues regarding content-based speech restrictions, are discussed. These arguments are rebutted to conclude that the doctrine has only adverse effects. The latter portion of the essay argues that the case Miller v. California provides legal precedent for altering the fighting words doctrine, so that specific contexts are considered. It also contends that doing so aligns with both the contemporary social zeitgeist and the state’s key interests

Indice d'un hérisson : étude et applications

Hedgehogs are a natural generalization of convex bodies of class C2+. After recalling some basic facts concerning this generalization, we use the notion of index to study differential and integral geometries of hedgehogs. As applications, we prove a particular case of the Tennis Ball Theorem and a property of normals to a plane convex body of constant width

ANALISIS TREND HARGA BAWANG MERAH DI KABUPATEN ALOR

Vegetable plants are one of the leading horticultural crops in the agricultural sector in Indonesia which are in great demand by the public because they have high nutritional content. Shallots are one of the leading vegetable commodities that are in great demand by the public as a cooking spice and as medicine. As the population increases and the development of industries that require shallot raw materials, the demand for shallots continues to increase. This research was conducted to determine price trends and forecast the price of shallots in Alor Regency in the future. The data analysis method used in this research is analysis of development trends and trends in onion price movements using the least squares method formula with the help of MS Excel. The research results show that the development of the price of shallots in Alor Regency from January 2020 to December 2022 shows the direction of an increase in prices each month of IDR. 259.59/kg with a determinant coefficient of R2 = 0.1064 or 10.64%. The forecast for the price of shallots in Alor Regency in 2023 is likely to continue to increase slowly. It is hoped that the government can maintain the stability of shallot prices both at the producer and consumer levels, because predictions of shallot prices in the future continue to increase

Tout chemin générique de hérissons réalisant un retournement de la sphère dans comprend un hérisson porteur de queues d’aronde positives

Hedgehogs are (possibly singular and self-intersecting) hypersurfaces that describe Minkowski differences of convex bodies in Rn+1. They are the natural geometrical objects when one seeks to extend parts of the Brunn–Minkowski theory to a vector space which contains convex bodies. In this paper, we prove that in every generic path of hedgehogs performing the eversion of the sphere in R3, there exists a hedgehog that has positive swallowtails. This study was motivated by an open problem raised in 1985 by Langevin, Levitt, and Rosenberg

Aproximaciones semióticas a El Pozo, de Juan Carlos Onetti

Los particulares y complejos procesos de modernización iniciados en el siglo XIX y profundizados en el siglo XX por países como Argentina y Uruguay conformaron una escena cultural que los escritores de la ciudad intentan describir con un nuevo lenguaje. Estos procesos se dan, a su vez, inmersos en una crisis económica, política y moral mundial cuyos emergentes son los grandes conflictos bélicos y que pone en cuestión el tema de la racionalidad moderna. En esta sociosfera, Juan Carlos Onetti irrumpe con "El pozo", uno de los textos inaugurales de la nueva narrativa latinoamericana. En él, la forma narrativa elegida (enmarcada en la tradición epistolar), los espacios descriptos, el tratamiento del tiempo, la temática de la marginalidad confluyen para mostrarnos la otra cara de nuestra modernidad: los monstruos que engendran los sueños de la razón. Por ello, en nuestra propuesta de lectura, que no deconoce las relaciones del discurso imaginario con su contexto histórico y social, ubicamos a "El pozo" como un texto "de frontera", estos es, según Lotman, un texto permeable que traduce las realidades de la periferia semiótica percibidas como caóticas desde el núcleo. La literatura de Onetti, transgresora en todos sus niveles, al codificar aquellas realidades cuestiona el núcleo semiótico dándole nuevos sentidos.Fil: Maure, Mario Fabián.

La galeria : de la logia a la pinacoteca

Tras definir la galería como tipo formal vinculado al sistema estructural porticado y esclarecer los usos comunes del término en las arquitecturas eclesiástica y civil, el análisis se centra en un recorrido histórico por la galería en la arquitectura resi-dencial. Los ejemplos más destacados de la Antigüedad, así como multitud de casos de la arquitectura medieval italiana y española son puestos a la luz y confrontados a través del hilo conductor del artículo. Una mirada original hacia un elemento arquitectónico que se recrea y permanece vigente hasta, al menos, los inicios del siglo XIX
