All hypertopologies are hit-and-miss

Naimpally, Somashekhar (Universitat Politècnica de València, 2002-04-01)

[EN] We solve a long standing problem by showing that all known hypertopologies are hit-and-miss. Our solution is not merely of theoretical importance. This representation is useful in the study of comparison of the ...
Caracterización hidráulica del riego por goteo en campo

Chamba, D.; Zubelzu, S.; Juana, L. (Universitat Politècnica de València, 2020-01-31)

[ES] Se analizan y proponen métodos de evaluación para determinar en campo la ecuación en gasto del emisor, las pérdidas de carga en ramales y porta-ramal y la uniformidad de distribución. Se han ensayado con ocho ramales ...
Completeness of Hutton [0,1]-quasi-uniformities induced by a crisp uniformity

Rodríguez López, Jesús; Romaguera Bonilla, Salvador; Sanchis, M. (2019)

[EN] In [25], Katsaras introduced a method for constructing a Hutton [0, 1]-quasi-uniformity from a crisp uniformity. In this paper we present other different methods for making this based mainly in the concept of a fuzzy ...
Di-uniform texture spaces

Ozcag, Selma; Brown, Lawrence M. (Universitat Politècnica de València, 2003-04-01)

[EN] Textures were introduced by the second author as a point-based setting for the study of fuzzy sets, and have since proved to be an appropriate framework for the development of complement-free mathematical concepts. ...
Estudio CFD de la inyección y mezcla de H2O aguas arriba de un compresor. Análisis de la posición y dirección de los inyectores.

Flor Madueño, Gerson (Universitat Politècnica de València, 2023-09-12)

[ES] La regulación de emisiones de los sistemas de propulsión presentes y futuros son y van a ser cada vez más restrictivas. Es por ello que es muy importante la optimización de cada módulo y componente con el fin de reducir ...
Evaluación de instalaciones de riego por aspersión en parcela y propuestas de mejora en el jardín del Campus de Vera de la Universidad Politécnica de Valencia (Valencia)

Calleja Lapeña, Fernando (Universitat Politècnica de València, 2015-03-04)

[ES] El riego de espacios verdes supone consumos de agua muy importantes dentro de las dotaciones urbanas, donde es preciso ajustar los volúmenes aportados. Los emisores de riego a presión usados pueden ser goteros, ...
Every finite system of T1 uniformities comes from a single distance structure

Heitzig, Jobst (Universitat Politècnica de València, 2002-04-01)

[EN] Using the general notion of distance function introduced in an earlier paper, a construction of the finest distance structure which induces a given quasi-uniformity is given. Moreover, when the usual defining condition ...
Metric spaces and textures

Dost, Senol (Universitat Politècnica de València, 2017-04-03)

[EN] Textures are point-set setting for fuzzy sets, and they provide a framework for the complement-free mathematical concepts. Further dimetric on textures is a gener- alization of classical metric spaces. The aim of this ...
On Modular b-Metrics

Romaguera Bonilla, Salvador (MDPI AG, 2024-10)

[EN] The notions of modular b-metric and modular b-metric space were introduced by Ege and Alaca as natural generalizations of the well-known and featured concepts of modular metric and modular metric space presented and ...
Optimization of the inlet air line of an automotive turbocharger

Serrano Cruz, José Ramón; Margot, Xandra; Tiseira Izaguirre, Andrés Omar; García-Cuevas González, Luis Miguel (SAGE Publications (UK and US), 2013-02)

This paper presents different aspects of air inlet behaviour near the inducer of a radial compressor and shows how the geometry can contribute to its stability and performance. Unfortunately, the space reserved for ...
Potassium distribution in drip irrigation with fertigation for different injection distances in the main line

Do Bomfim, Guilherme V.; Manzano Juarez, Juan; De Azevedo, Benito M; Vasconcelos, Denise V; Viana, Thales V. De A. (Sociedade Brasileira de Engenharia Agrícola, 2014)

[EN] The purpose of this research was to evaluate the K2O distribution uniformity by surface drip irrigation at Universitat Politecnica de Valencia, Valencia, Spain (39º 29′ N, 0º 23′ W, 20 m). The irrigation was performed ...
Uniformly refinable maps

Macías, Sergio (Universitat Politècnica de València, 2023-04-05)

[EN] We introduce the notion of uniformly refinable map for compact, Hausdorff spaces, as a generalization of refinable maps originallydefined for metric continua by Jo Ford (Heath) and Jack W. Rogers, Jr., Refinable maps, ...
