Implementación del procesador RV321 en el programa Logisim-Evolution
Get PDFEste Trabajo de Fin de Grado se centra en la implementación de un procesador basado en la arquitectura RISC-V, específicamente en el conjunto de instrucciones RV32I, utilizando la herramienta de simulación Logisim-Evolution. El objetivo principal es implementar un procesador funcional que pueda ser utilizado en hardware real, como una FPGA, o en futuros proyectos que busquen ampliar la capacidad de instrucciones del procesador.
A lo largo del documento, se detallan los pasos para la implementación de las instrucciones de tipo R, I, S, B, U y J, así como la integración de todos los componentes en un único sistema. La combinación de RISC-V y Logisim-Evolution ofrece una poderosa herramienta para la enseñanza de la arquitectura de computadores y el diseño de sistemas digitales que se ha aprovechado para desarrollar una serie de prácticas de laboratorio. Estos guían al estudiante a implementar un procesador desde cero abordando la arquitectura del procesador de manera progresiva.
La implementación final del procesador permite la simulación de instrucciones básicas y avanzadas, proporcionando una visión integral del funcionamiento de los procesadores modernos basados en la arquitectura RISC-V.This degree dissertation focuses on the implementation of a processor based on the
RISC-V architecture, specifically the RV32I instruction set, using the Logisim-Evolution
simulation tool. The main objective is to implement a functional processor that can be
used in real hardware, such as an FPGA, or in future projects aimed at expanding the
processor’s instruction capacity. Throughout the document, the steps for implemen ting R, I, S, B, U, and J type instructions are detailed, as well as the integration of all
components into a single system. The combination of RISC-V and Logisim-Evolution
offers a powerful tool for teaching computer architecture and digital system design,
which has been utilized to develop a series of laboratory practices. These guide stu dents in implementing a processor from scratch, progressively addressing the processor
architecture. The final implementation of the processor allows the simulation of both
basic and advanced instructions, providing a comprehensive view of the operation of
modern processors based on the RISC-V architecture.Departamento de Tecnología ElectrónicaGrado en Ingeniería en Electrónica Industrial y Automátic
LHCb VELO Bandgap Temperature Calibration
No full textThis report presents the Summer Student Program project focused on the calibration method for temperature measurement of each ASIC within the VErtex LOcator, a subdetector of the LHCb experiment at CERN. Using the WinCC Open Architecture tool, a control panel is designed to display calibrated temperature data along with raw temperature and voltage readings in real-time. This panel enhances error identification and provides more precise experiment control when operating at power levels different from the operational state
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
