Tool for fast mismatch analysis of analog circuits

A tool is presented that evaluates statistical deviations in performance characteristics of analog circuits, starting from statistical deviations in the technological parameters of MOS transistors. Performance is demonstrated via the analysis of a Miller OTA in two different configurations and a linearized CMOS transconductor. The CPU time is reduced by a factor of 25 to 90 with respect to conventional Monte Carlo simulation, while maintaining similar accuracy in the computations

Caracterización físico-química de los morteros y de las pinturas murales de la villa romana de El Ruedo (Almedinilla, Córdoba)

In the present survey, we have proceeded to the analysis of Roman mortars and paintings in two rooms from a villa at El Ruedo (Almedinilla, Cordoba ). They were used different techniques or procedures, such as: analysis granules size, X ray diffraction and scattering reflection. It has been noticed that materials of the different decorations correspond to different compositions provenient from different sites (different canters). As far as colours are concerned, they were established the different parameters which define them in every international system. The scattering reflection techniques allowed us to identify the pigments, emphasizing that their mixtures are usually based upon only in one colour, lighter or darker.En el presente trabajo se ha procedido al análisis de los morteros y pinturas romanas de dos estancias de la villa de El Ruedo (Almedinilla, Córdoba). Se han utilizado diferentes técnicas, tales como análisis granulométrico, difracción de rayos X y reflectancia difusa. Se ha podido constatar que los materiales de las diferentes decoraciones presentan diferentes composiciones y por tanto provienen de sitios diferentes (canteras diferentes). Con respecto al color se han obtenido los parámetros que lo definen en los distintos sistemas internacionales. La técnica de reflectancia difusa ha permitido la identificación de los pigmentos, poniendo de manifiesto que sus mezclas se basan normalmente en uno solo, aclarado o oscurecido

An advanced symbolic analyzer for the automatic generation of analog circuit design equations

A tool for symbolic analysis of analog integrated circuits is presented featuring accurate simplification, pole/zero extraction, and tools for parametric AC circuit characterization. The program, called ASAP, uses signal flowgraph methods and has been written in C for portability. In its current version, ASAP is able to deal with the complexity levels arising in typical analog building blocks when described by device-level models. The ASAP inputs and outputs, the architecture, and the graphical interface are discussed

Modulación de la expresión de citoquinas por cambios metabólicos y estrés de retículo endoplasmático

El sistema inmunitario se ha desarrollado a lo largo del proceso evolutivo para combatir las infecciones y proteger al organismo frente a elementos que suponen una amenaza para su integridad mediante una respuesta que permita la supervivencia. Por este motivo, el sistema inmune es el encargado de mantener la homeostasis celular mediante la eliminación del patógeno y reparación del daño causado. Las células del sistema inmunitario tienen la cualidad de poder diferenciar lo propio de lo extraño, “self non-self model” (1) sugerido por Burnet en los años 60 cuando trataba de explicar la tolerancia inmune. Posteriormente, Janeway precisó con más acierto esta cualidad al enunciar como principio funcional del sistema inmune la propiedad de distinguir lo “Propio no infeccioso de lo infeccioso no propio”. Este concepto ha permitido reconocer el papel de los patrones moleculares como elementos fundamentales en el reconocimiento de los patógenos. Como una continuación de esta teoría del reconocimiento por el sistema inmune, Matzinger P. sugirió el modelo de peligro “Danger model” (2) que añade a la capacidad del organismo para discriminar lo potencialmente peligroso mediante el reconocimiento de patógenos, la identificación de señales de alarma procedentes de tejidos dañados.Máster en Investigación Biomédic

Determinants of tourism destination competitiveness in the countries most visited by international tourists: Proposal of a synthetic index

Tourism destination competitiveness is a multidimensional concept that is widely studied in the academic literature, but multiple factors make its measurement a difficult task. In this article, we design a synthetic index to rank the 80 countries that attract the majority of international tourists by level of tourism competitiveness. In order to do this, we use all of the simple variables included in the 2017 Travel & Tourism Competitiveness Index, proposing a new methodology for the construction of this synthetic index, which it solves the problems of aggregation of variables expressed in different measures, arbitrary weighting and duplicity of information; issues that remain unresolved by the TTCI. Likewise, we analyse the most influential dimensions in tourism competitiveness. Air transport infrastructures, cultural resources and ICT readiness are the key dimensions that explain the main disparities.Funding Agency Spanish Ministry of Economy, Industry and Competitiveness State Research Agency (SRA) European Union (EU) ECO2017-86822-Rinfo:eu-repo/semantics/publishedVersio

Test item taxonomy based of functional criteria

There are many taxonomies that try to classify and apply some consistency to the very many item types currently in existence. They all have various limitations, however, such as ambiguous classification criteria, little discrimination between format types, and referring almost exclusively to pen-and-paper or screen-based items. This paper aims to overcome these limitations by proposing a new item format taxonomy based on functional criteria. Current classifications are reviewed, the criteria they are based on are examined and their limitations are identified. The proposed alternative classification identifies four essential components of items according to function: the structure of the included content, the device used for transmission of the question to the examinee, the device for receiving the response, and the instructions to the examinee about how to understand and respond to the item. The combination of different facets of these four components allows any format of item to be classified, both existing formats and those that may appear in the future. In addition to systematically and coherently classifying items, this new taxonomy may also be of great utility in the construction and research of new items. The proposed model is illustrated by examples showing how specific items are classified, using a checklist as a guide.Ministerio de Economía y Competitividad de España PSI2014-56114-PMinisterio de Economía y Competitividad de España PSI2017-85724-
