Comments on "Internal impedance of conductors of rectangular cross section"

The alternate current (ac) internal impedance of rectangular cross-sectional conductors used as transmission lines and interconnects in microwave and digital printed circuits were analyzed. The difference between the real and imaginary parts of internal impedance to the existence of right-angle corners in the rectangular cross-sectional geometrics were studied. The corners are responsible for the nonconstant distribution of the currents along the periphery of the conductors. The consideration of incremental inductance was correlated to nonperfect nature of the conductors rather than internal inductance

Metalinguistic and metacontextual effects

Some assertions that are not about the meanings of the words used can transmit information about those meanings. In (Mena, 2022) I offered an explanation of that phenomenon purely in semantic terms. The novelty of that theory consists in including interpretations of language in circumstances of evaluation: the parameters relative to which we evaluate the contents of linguistic expressions. In this paper I argue that assertions of sentences containing indexicals can communicate information about the context of use, even though those sentences are not about contexts. Given this, I offer an extension of my theory of metalinguistic effects to model indexicals in an analogous way. Also, I discuss the many ways in which the theory presented here differs from other bidimensional semantics

Modelos e tendências da criação e gestão de marcas para a comunicação corporativa: proposta de Modelo Marcas 3'S

The brand communication is a concrete strategy of organization when this defines its goals, which messages you want to pass as well as what targets to reach. This article focuses on some authors and focuses on the importance of brand communication occupies in the definition of the Organization's strategy. In particular in the statement of the research project, that methodology to new approach for Brand Tree Method, which integrates 3 ´ S and does the merger between the research, the intended differentiation and the implementation of the project. The experience of the investigator in the creation, management and deployment of brands allowed the construction of brands allowed the construction of a methodology that takes the brand as an active and integral part of the company. Is in this sense that it proposes a new methodology of creating and managing brands called ´ 3 s.La comunicación de la marca es una estrategia concreta de la organización cuando ésta define sus objetivos, los mensajes que desea transmitir y los objetivos a alcanzar. Este artículo se centra en la importancia que la comunicación de la marca ocupa en la definición de la estrategia de la organización.

Diseño y desarrollo de un sistema con un módulo para la administración de los recursos técnicos utilizando un IVR para la empresa Telalca S.A.

Automation of processes using an integrated to assist the management of staff resources helps companies become more dynamic, because they can control and manage their processes in a better way, with more tools to work, they can store information in a more reliable and streamline way. The work below describes the solution designed to automate the way it manages the technical department, primarily through the creation of a system that manages all the employees of the company, created so that each department has full independence and that can still add modules depending on the requirements the company has. Followed by the analysis of the current way the technical area works, coupled with the creation of a module that automates the processes of the technical area and allow to control and monitor more effectively the technical staff.La automatización de procesos utilizando un sistema integral que ayude a la administración de los recursos del personal ayuda a las empresas a ser más dinámicas, debido a que pueden controlar sus procesos de mejor manera, tener mayor cantidad de herramientas para el trabajo, conservar la información de una forma más confiable y agilitar su trabajo. El trabajo a continuación describe la solución creada para automatizar la manera en que se gestiona el departamento técnico de la empresa Telalca, primeramente a través de la creación de un sistema que administra a todos los empleados de la empresa, creado de tal manera que cada departamento tenga total independencia y que se puedan seguir añadiendo módulos dependiendo de los requerimientos que se tenga. Continuo del análisis del funcionamiento actual del departamento técnico, unido a la creación de un módulo que automatice los procesos del área técnica y que permita controlar y monitorear de una manera más eficaz al personal técnico

El delito de asesinato en la legislación penal salvadoreña

En este obligatorio trabajo de tesis para mi doctoramiento, he realizado algo sencillo pe ro tratando de cubrir los aspectos más importantes que rodean al delito objeto de esta tesis, que se titula: "El Delito de Asesinato en la Legislación Penal Salvadoreña". Es consabido que sobre este delito, doctrinariamente hablando, los grandes maestros expositores de Derecho Penal lo han expuesto ya todo, pero creo que en el presente trabajo encontramos modalidades propias en cuanto se refiere al delito de asesinato en nuestra legislación, con la secuencia de reformas sufridas a través del tiempo en el Código Penal, exponiendo también mi opinión en el sentido de como sería conveniente realizar una nueva reforma al Artículo 356 del Código Penal Vigente, en el que se tipifica el delito de asesinato

Quasi-TM MoL/MoM approach for computing the transmission-line parameters of lossy lines

This paper presents a quasi-TM approach for the fundamental mode of transmission lines with semiconductor substrates and nonperfect metallic conductors. The approach has allowed us to develop a transmission-line model by properly defining frequency-dependent parameters in terms of the quasi-static electric potential and the electric current density along the propagation direction in the line. The previous quasi-TM analysis avoids the involved numerical root finding process typical in full-wave analysis, and overcomes the limitations of the conventional quasi-TEM approach to account for the effects of the longitudinal currents present both in the lossy substrates and in the nonperfect conductors. The transmission-line parameters have been computed by a hybrid technique that combines the method of lines with the method of the moments (MoM). The total CPU effort has been considerably reduced thanks to the possibility of finding closed-form expressions for the reaction integrals appearing in the MoM. Comparisons with previous computed and measured results show the validity of the present modelMinisterio de Educación y Ciencia TEC2004-04249-C02-02, TEC2004-0321

Near-field enhanced imaging by a magnetized ferrite slab

This letter demonstrates the near-field imaging enhancement at microwave frequencies of two-dimensional sources by a ferrite slab magnetized to saturation. It is shown that this effect is based on the nonreciprocal amplification of magnetostatic surface waves (MSSW) across the ferrite slab. The inclusion of losses in our analysis has also made it possible to prove this effect for realistic yttrium iron garnet ferrite samples. For ferrite slabs of width d, the resolution at the image plane (at a distance 2d from the source) is better than the resolution in air at a distance d of the source, which leads to an equivalent air length of the ferrite slab less than zero. Since the constitutive parameters of saturated ferrites depend on the external magnetizing field, the operation frequency of the proposed imaging devices can be tuned by varying this biasing field.Ministerio de Ciencia y Tecnología TEC2004-03214, TEC2004-04249-C02-0

Comment on "electromagnetic resonances in individual and coupled split-ring resonators"

Resonances appearing in split-ring resonators (SRR) were explained by the theory about the magnetoelectric coupling in the tensor polarizability of these particles. The relative strength of the resonances was explained from the numerical values of the different polarizabilities computed with the model. No resonant absorption was observed for incident waves with the perpendicular polarization
