Abstract The principal one-particle operators of quantum theory of Proca’s free field are derived using a method associating to any operator in a configuration representation a pair of operators acting directly on part...

Abstract Since the mid of 1990th, Mosul city over all Iraq cities, is used widely the local power diesel generators. The generators exhaust emits a large amounts of hydrocarbon gases, including, of course, carbon dioxide...

A theoretical and experimental study on the iodination of BODIPY dyes with different degrees of substitution has been developed. Polyhalogenated BODIPYs synthesized in this work are the first examples of this type of dy...

In the context of full-scale war, the energy crisis has become one of the key factors in the transformation of Ukraine's economic security, directly affecting macroeconomic and social stability and the state's institutio...

In this paper we raise the question “why is agreement so common across natural languages?”. We will argue that the challenge of grammar inference in natural and artificial languages provides key insights into the ubi...

"A new class of linear sequence generators based on cellular automata is here introduced in order to model several nonlinear keystream generators with practical applications in symmetric cryptography. The output sequence...

The resolution of optimization problems is of great interest nowadays and has encouraged the development of various information technology methods to attempt solving them. There are several problems related to Software E...

Since huge amounts of spatial data can be easily collected from various applications, ranging from remote sensing technology to geographical information system, the extraction and comprehension of spatial knowledge is a ...

La generación de energía a partir del viento se ha convertido en un tema de alta prioridad en muchas regiones del mundo en las últimas décadas, durante las cuales ha crecido en forma continua la capacidad eólica ins...

Esta tesis está dedicada al estudio de esquemas y estrategias de control de micro centrales eólicas autónomas. Se ha puesto especial énfasis en el desarrollo de un sistema robusto, que requiera mínimo mantenimiento ...

"El trabajo está compuesto por un análisis de la evolución y situación actual de cada uno de los agentes del MEM (Distribuidores, Grandes usuarios, Generadores, Transportistas y CAMMESA), a nivel técnico y económic...

A atividade antioxidante in vitro do extrato de folhas jovens e adultas de Tabebuia heptaphylla (Vell.) Toledo (ipê-roxo) foi estimada pela prevenção de formação de espécies reativas do ácido tiobarbitú- rico (TB...

The use of generic and generative methods for the development and application of interactive educational software is a relatively unexplored area in industry and education. Advantages of generic and generative techniques...

La especialización de programas es una manera particular de producir programas automáticamente. En ella se utiliza un programa fuente general dado para generar diversas versiones particulares, especializadas, del mismo...

By decomposing the image formation process into a sequential application of denoising autoencoders, diffusion models (DMs) achieve state-of-the-art synthesis results on image data and beyond. Additionally, their formulat...

We show that the large N limit of certain conformal field theories in various dimensions include in their Hilbert space a sector describing supergravity on the product of Anti-deSitter spacetimes, spheres and other compa...
