Ítem Parques de la localidad de Teusaquillo : Estudio e implementación de un sistema de información geográficaQuijano Wilches, Luis Fernando; Trujillo Vélez, Emiro Alberto; Salgado Ramírez, Leonardo Andrés; Quijano Wilches, Luis Fernando [0000-0001-6560-0259]; Trujillo Vélez, Emiro Alberto [0000-0002-8956-6451]This book is the product of a technical study of the parks in the town of Teusaquillo, intended for the development of physical, sports and recreational activity. The work consisted of carrying out an inventory of the parks that the town has, taking into account the district registry of parks of the District Institute for Recreation and Sports (IDRD), which allowed the generation of a geographic information system with accessibility for the entire community. It is thus proposed as a study that can provide the guideline for subsequent web developments about the sports venues of Teusaquillo, other towns and municipalities at the national level, adding greater functional components that respond to the boom that digital maps are having. in cyberspace.Ítem Multibot: Robótica aplicada al rescate urbanoPérez Pereira, Miguel Ricardo; Bermúdez Bohórquez, Giovanni Rodrigo; Rairán Antolines, José Danilo; Pérez Pereira, Miguel Ricardo [0000-0001-7487-2600]; Bermúdez Bohórquez, Giovanni Rodrigo [0000-0002-4744-160X]; Rairán Antolines, José Danilo [0000-0002-1213-7333]Robotics has become a great small pretext for the development of research activities, study and implementation of alternatives, some of them innovative and entrepreneurial, that facilitate the solution of everyday problems in society. “Multibot. Robotics applied to urban rescue", is a book that collects the fundamental aspects, achieved in the development of a research project financed by the District University Francisco José de Caldas and carried out by the research groups in Autonomous Mobile Robotics (Rome) and in Electronic Control (Gice). Among the fundamental aspects presented is the development of reactive cooperation algorithms, developed in a team of four mobile robots, each with sensory fusion algorithms, artificial vision and bioinspired systems through the implementation of a novel proposal of controllers. based on emotions, all with the main objective of providing the Colombian and international scientific community with new study elements in the area of service robotics.Ítem Modelo de asignación multicanal con equidad para la movilidad espectral en redes de radio cognitivaHernández Suárez, César Augusto; Márquez Ramos, Hans Raúl; Pedraza Martínez, Luis FernandoCognitive radio networks (CRN) respond to the need to optimize existing resources within the network and fundamentally the use of the spectrum. This translates as an opportunity to improve the level of service for users of wireless technologies, making opportunistic use of the available spectrum, and therefore improving spectral efficiency. CR provides a use efficient spectrum allowing the secondary user (SU) to opportunistically take advantage of the portions or channels of the licensed spectrum that are not being used by the primary user (PU), which are called spectral opportunities. This research book aims to develop a model that allows EDs to take advantage of these spectral opportunities, including through a multi-channel transmission approach, As long as the number of spectral and SU opportunities allows it, that is, to SUs with real-time applications that require greater bandwidth, the model could assign several frequency channels for transmission. However, the above will only be possible if the number of SU requiring the spectral resource is less than the number of spectral opportunities, so that the proposed model will incorporate a Fairness criterion to guarantee an allocation equitable provision of such opportunities to SUs.Ítem Modelo adaptativo multivariable de handoff espectral para incrementar el desempeño en redes móviles de radio cognitivaHernández Suárez, Cesar Augusto; Páez-Parra, Ingrid Patricia; Giral Ramírez, Diego Armando; Páez-Parra, Ingrid Patricia [0009-0008-1033-8714]; Giral Ramírez, Diego Armando [0000-0001-9983-4555]; Hernández Suárez, César Augusto [0000-0001-9409-8341]Spectral handoff, in cognitive radio networks, occurs when the secondary user must leave the frequency channel they are using and continue their communication at another spectral opportunity. This process is a key aspect to guarantee adequate quality of service and improve performance in secondary user communications. This research book aims to present a proposal for a multivariate adaptive spectral handoff model for mobile cognitive radio networks. For this purpose, three algorithms were developed for decision-making during a spectral handoff, with different approaches: fuzzy, feedback and predictive; These make up the proposed adaptive multivariate spectral handoff model. To evaluate the level of performance of the developed algorithms, a comparative analysis was carried out between them and the most relevant spectral handoff algorithms in current literature. Unlike related works, the benchmark was validated through a trace of real spectral occupancy data captured in the GSM and Wi-Fi frequency band, which models the real behavior of primary users. In the validation phase, eight evaluation scenarios were proposed, considering two types of networks: GSM and Wi-Fi, two classes of applications: real-time and best-effort, two traffic levels: high and low, and ten evaluation metrics.Ítem Memorias y olvido : sala de exposiciones ASAB (1996-2013)Sanabria Hernández, GustavoWith this publication, a contribution is made to the field of art based on the course of the artistic activity that has been carried out between 1996 and 2013, in the ASAB Exhibition Hall. A not very past is reconstructed distant as a specific form of visibility, and thus establish bridges and connections that are currently circumscribed with respect to the memory of this exhibition space. In the midst of oblivion and its possible fissures, an event of the creative processes has been reconstructed through evidence, records, dialogues, convictions, certainties and memories with directors, teachers, artists, students and curators who have taken part in the consolidation of the room of exhibitions. The artistic, museological, curatorial, exhibition and academic practices point out the importance, pertinence and relevance of the ASAB Exhibition Hall in the artistic and cultural field, as it constitutes a stage of great importance that affects the events of the local scene in Bogotá , in the national order and its links in the international context.Ítem Memoria al aire : Gubernamentalidad, radiodifusión y nación en Colombia (1940-1973)Amador, Juan Carlos; Amador, Juan Carlos [0000-0002-5575-1755]Memory on the Air: Governmentality, Broadcasting and the Nation in Colombia (1940-1973) is a book that exposes how built various nation projects in Colombia, throughout this period, through the performative nature of the speeches and narratives broadcast by the National Radio Broadcasting Station of Colombia (RNC). The RNC not only intended to be an informational organ but was a constituent part of a series of government technologies that performed different functions in the population. These government technologies were made up of two configuration planes of the social order: the rationality of government (through the implementation of nation projects) and the conduct of conduct (based on the government management of the Colombian citizen). After exposing in chapter one the reconstruction of the media field, national projects and popular cultures in Latin America and Colombia, chapter two presents the first moment (1940-1945), which shows how, through the RNC and the official press, emphasis was placed on a nation that is “culturalized,” that is integrated into its government as a single social body and that is physiologically sanitized. and the moral. The third chapter (1946 and 1957) explains how the nation moves towards a project of national reconstruction, re-Christianization and popular integration. Finally, in chapter four (1958-1973), the national project is oriented towards development, influenced by the Alliance for Progress program. In addition to the implications that the Front National and pacification strategy to mitigate “independent republics,” development brought with it corpopolitics, a crucial strategy in which the individual body, family, and parenthood became matters of government.Ítem Manejo eficiente del agua en sistemas comunitarios de riego AndinosGutiérrez-Malaxechebarría, Alvaro-Martín; González Umaña, Jerson Leonardo; Gutiérrez-Malaxechebarría, Alvaro-Martín [0000-0002-2306-1610]; González Umaña, Jerson Leonardo [0000-0002-4453-8537]Community irrigation systems are extremely interesting because they combine infrastructure, whose elements cannot always be understood by engineering, and very rich and varied agreements to access water, the combination of infrastructure and social institutions allow water to be managed. This is one of the few documents that articulately addresses technical elements and the social organization of community water systems. To do this, the researchers focus on a particular locality in the Colombian Andean area, whose results and reflections They can be extrapolated to other mountainous areas of the tropics. Although this book is the result of a research project, it is written in an entertaining way seeking access to all audiences interested in the topic of community irrigation systems. It gives indicators of water losses, efficiency of irrigation application, the rich social agreements on which these systems are based and the perceptions of users, as well as the terrible policy and legal limitations to respond effectively to the reality so well understood by irrigators. That is to say, the authors shed light on the operation and the elements of success that could be replicated, as well as some reflections on how these systems can be improved based on the action of the users themselves, public policies, and the improvement of infrastructure and other elements that favor rural development, articulating with management of water, particularly in rural areas of the high tropics.Ítem El proceso de argumentación en la formación inicial de docentes: una experiencia mediada por Dígalo y SimasLandazábal Cuervo, Diana Patricia; Gamboa Mora, María Cristina; Gamboa Mora, María Cristina [0000-0001-8459-099X]This book presents research results regarding training in argumentation as a basis for critical thinking. The exercise of proposing problems and questions to promote argumentation has proven to be positive in the construction of knowledge, as well as using digital learning environments to generate motivation and promote new ways of learning and training teachers. The conjugation of strategies in which the Digalo and Simas environments were used contributed to innovation in the classroom, and this allowed students to improve their argumentative skills, generate dialogue and promote a participatory culture necessary in the political formation of subjects. . In this book, researchers will be able to find a theoretical framework that supports the research carried out, as well as the findings when applying these strategies in initial teacher training. In addition, processes and transformations are evident during the development of training, and the importance of including this type of tools in face-to-face classes. Training for participation is relevant for teacher training, so it is recommended to continue researching and systematizing the use of Dígalo and Simas in educational contexts. This research contributes to the discussion on teacher training, critical thinking, the generation of skills for the 21st century and the use of digital technologies in education.Ítem Imaginarios sociales en los textos escolares de lengua castellanaGuzmán Munar, Margoth; Guzmán Munar, Margoth [0000-0003-0483-1920]This book offers a tour of invisible geographies, with logic, canons, conceptions and imaginaries, on the one hand, and discursive and iconographic actions, on the other. It was started from the fact that the school textbook is an essential element that implies information about an area or discipline, in a specific context and time. In this framework, school textbooks cease to be a strictly educational problem and become a sociopolitical one, since the purpose of education is to train for knowledge within a coexistence; Its object is no longer just the speeches, but all the demonstrations that require the organization of new alternative and democratic curricula that make possible and fun worlds for the boys and girls of this country who need it so much. The above calls for language as a premise for the acquisition of knowledge, to resort to the text, as well as to work on strategies that allow the construction of innovative pedagogies in which dialogic and equitable processes are installed that involve critical thinking from their realities.Ítem Modelo de predicción de la ocupación espectral para el análisis y diseño de redes de radio cognitivaPedraza Martínez, Luis Fernando; Hernandez Suarez, Cesar Augusto; Salgado Franco, Lizet Camila; Hernández Suárez, César Augusto [0000-0001-9409-8341]With the arrival of broadband multimedia applications and the growing demand for access to the information network of mobile devices, it is essential to improve the efficiency in the use of the electromagnetic spectrum to cover the needs of high bit rates proportional to the services multimedia. For this reason, cognitive radio has become one of the most researched paradigms in radio communications to optimize the use of the radio spectrum. Within the spectral mobility of cognitive radio networks, proactive handoff strategies turn out to be the most beneficial for the primary user, given that there is no interference period in which the two users (primary and secondary) coexist; However, the problem with this strategy lies in the precision of the prediction of the arrival of the primary user, that is, in the prediction of the spectral occupancy of the licensed band. This book proposes the development of a spectral occupancy prediction model, which takes into account the relevant characteristics of the spectrum behavior, based on measurements carried out in an urban environment, which can contribute to the improvement of proactive handoff and, therefore, hence, the performance of cognitive radio networks.Ítem Marcas y marcajes: otras memorias y luchas en Bogotá a finales del siglo XX y principios del XXCastiblanco Roldán, Andrés; Castiblanco Roldán, Andrés [0000-0002-7272-0133]This book proposes a critique of society and culture based on memory and the imaginary; observes some inputs that manage and produce stories and images, as pieces or components of a marking system that establishes a series of sensory regimes, which associate and articulate creative, advertising, narrative, audiovisual and multimedia processes, among others. Issues such as the spatial-cultural conditions where commerce and the market detach themselves from their material niches to transform themselves into metaphors, both of the everyday social world, and of great interpretations of economies and nations, among others, are analyzed from the marking in its sociocultural dimension as a technical memory that produces the assemblage of modes of appropriation and assembly with the brand as a commercial imprint. Based on the analysis of Bogotá, this book warns of the presence of new fractures and tensions in the field of the questioned collective memory and its future in urban spaces.Ítem Nociones de cuerpo y entrenamiento en danza contemporánea Colectivos Danza Común y CortocinesiMorales Rodríguez, Yudy del RosarioArtistic Studies seeks to expand the range of approaches, crossings and movements to delve into aspects of artistic creation. This artistic ethnographic story was aimed at solving the following research question: What do Danza Común and Cortocinesis, two contemporary dance collectives from Bogotá, understand by body and by training? In the introduction they explain the reasons, intentions and methodological route followed. The chapters and the epilogue give an account of the conceptual theoretical foundation of contemporary dance and the notions of body and training from the perspective of philosophers and artists; the beginnings, experiences and criteria on these notions in the voices of the protagonists/confidants of two dance groups in the city of Bogotá: Danza Común and Cortocinesis; in addition to the vision of the author/researcher. The notion of body is assumed under an integrative meaning of the bodily valences that identify the human being; the need for training as a transformative space-place of the body that we are, especially in the field of artistic expression that constitutes dance and summarized in this work under the definition of corpopoiesisÍtem Literatura infantil y juvenil colombiana: problemas, tendencias, obras y autores (1990-2012)Borja Orozco, Mirian Glidis; Alonso Galeano, Nelson Arturo; Borja Orozco, Mirian Glidis [0000-0003-1302-2690]; Alonso Galeano, Nelson Arturo [0000-0003-2172-1408]In Colombia, there are authors and works that describe children's and youth literature (LIJ), whether from the idea of adaptation for children and young people of “great literature” books for adults, or literature written for these populations. or literature that children and young people appropriate for themselves, based on the recommendation of an adult or from social networks and the mass media. Starting from the question: what are the problems, trends, authors and most representative works of Colombian children's and youth literature in the last twenty years? and with the interest in accounting for the evolution of Colombian literature and the place that the LIJ has been forging in it, this book presents the result of an investigation that investigated issues such as the concepts of children's and youth literature, the representations of child and young people as reading subjects, the place of the LIJ in the constitution of the canon of Colombian literature, and periodization within the framework of problems and trends of the Colombian LIJ, between 1990 and 2012Ítem Historia del pensamiento pedagógico colombiano: Una mirada desde los maestros e intelectuales de la educaciónJiménez Becerra, Absalón; Jiménez Becerra, Absalón [0000-0002-2500-6498]The reader will find gathered here seven biographical fragments intended to reactivate the memory of Colombian pedagogical practice, according to an expression by Olga Lucía Zuluaga. This is a selection of the vital and intellectual trajectories of men such as Don Martín Restrepo Mejía (1861-1940), official pedagogue of the Regeneration and the Conservative Hegemony; Don Agustín Nieto Caballero (1889-1975), emblematic pedagogue of the liberal Republic and disseminator of active Pedagogy; Dr. José Francisco Socarrás (1906-1995), rector of the Escuela Normal Superior, the first public institution for university training of teachers; the teacher Estanislao Zuleta (1935-1990), self-taught philosopher and intellectual critic of the capitalist system and its educational institutions; Marco Raúl Me jía Jiménez (1952), promoter of critical pedagogy and manager of popular education in Colombia; Francisco Cajiao Restrepo (1947), graduate in philosophy and economics, driver of contemporary debate in education; and “professor” Antanas Mockus Šivickas (1952-), mathematician, philosopher, pedagogue, university rector, mayor of Bogotá, presidential candidate and current senator-elect for the Green Alliance party. They have been, without a doubt, significant actors in the history of our modern educational system—in the broad arc that spans from the end of the 19th century to the beginning of the 21st century—and their lives provide keys to understanding us. However, it is not easy to find a common name for all of them: teachers, pedagogues, educational intellectuals, educational policy officials, cultural agents...? It is not allowed to respond with an easy “all of the above”, because although each of them held several of those positions, perhaps all of them, not all of them were schoolteachers, nor were they all such State officials… But there is one more reason. deep to think twice, before labeling them as a group or each one in particular: the historical reason that consists of understanding that all these names or roles do not apply in the same way in different periods of our "educational evolution." Calling yourself a “pedagogue,” let's say, did not mean the same to Don Martín Restrepo Mejía and his contemporaries in 1910 as it does to us contemporaries of “Professor” Antanas Mockus or Maestro Estanislao Zuleta. Although the persistence of a certain family resemblance must be recognized, we are not sure that the aforementioned evolution of our educational systems has flowed in a single direction, without leaps or breaks, without setbacks or recurrences.Ítem Entornos de búsquedas navegacionales a partir de esquemas de representación de conocimientoGaona Garcia, Paulo Alonso; Montenegro Marín, Carlos Enrique; Martín-Moncunil, David; Gaona Garcia, Paulo Alonso [0000-0002-8758-1412]; Martín-Moncunil, David [0000-0003-2422-9005]Currently there are repositories and digital libraries that give access to thousands of resources cataloged and organized according to the descriptions of their collections. Most of this large number of resources do not have a scope and/or visibility that allows them to be consulted in their entirety by current conventional search methods, such as textual search engines. Under this premise, this book proposes a series of visual search strategies based on knowledge representation schemes (ontologies and thesauri), through the use of navigational interfaces that allow improving the current conditions of access to the majority of these collections. of digital resources. To do this, user-centered design principles and aspects related to usability will be used, with the purpose of exploring possible ways to display information within a collection of digital resources hosted in a repository, and analyzing their differences in order to reach conclusions that allow you to identify advantages and disadvantages of each of them for their implementationÍtem Los géneros discursivos en las interacciones cotidianasMontoya Castillo, Mario; Roa Sánchez, Óscar Felipe; Forero Olaya, Nicolás Camilo; Barragán Escarpeta, Víctor Alfonso; Pinzón Ordoñez, Carlos Andrés; Montoya Castillo, Mario [ 0000-0001-6347-384X]; Forero Olaya, Nicolás Camilo [0000-0002-7163-6087]This book is the result of the investigative work of the students who make up the Hermeneia Research Seedbed, articulated with the work carried out by the Language, Culture and Identity research group. The research is aimed at identifying the descriptive possibilities of studies on discursive genres, taking as an object of analysis the different discourses that teachers face in their professional experience: television programs, new ways of communicating in internet, literature and the very discourse of the teacher who teaches. In the chapters the authors insist on the hypothesis that discursive genres are not reduced to the description of their textual properties at the time of being studied, but rather that these properties are part of a whole together with the social environments where they are produced. and interpreted. This work is an invitation to study the discourses that can be found in the territories of school and daily life; to the examination of the different elements that are taken into account to create the labels on the texts and the organization of the discursive experience; the difficulties that each text poses to the speaker, the knowledge that the speaker must have in order to produce a text and the elements to take into account for the understanding of these discourses framed in the field of everyday life.Ítem El secreto de la laberíntica soledad: Huellas de la identidad social en la obra del joven García MárquezGarcía-Dussán, Éder; García-Dussán, Éder [0000-0002-6635-2725]The book brings together biographical, historical and ideological data of the writer Gabriel García Márquez, together with the analysis and interpretation of his original short stories, twenty-two stories collected in the books Ojos de perro azul and Los funerales de la mama grande. Through various analytical operations on these narrative structures, and feeding on the importance of the impulses that motivate an author to found a literary company, the study shows how the young García Márquez represents the profile of a social identity transposed into the creation of a community of silent, solitary and undefined subjects, mere parasites harassed by effective actions superior to them and who interact in atmospheres that conceal a violence that has become a founding myth; all this cultivated in claustrophilic but porous territories. Thus, the outline of a social grammar energized in a geography of terror that exposes the living dead is founded; a pere-literary version of the historical we that supports the idea of a nation crossed by moral and physical repressions that have served as midwives of our society.Ítem Desarrollo de una mezcla asfáltica tibia bajo criterios técnicos y medioambientalesRondón Quintana, Hugo Alexander; Zafra Mejía, Carlos Alfonso; Fernández Gómez, Wilmar Darío; Rondón Quintana, Hugo Alexander [0000-0003-2946-9411]; Fernández Gómez, Wilmar Darío [0000-0001-6339-8050]; Zafra Mejía, Carlos Alfonso [0000-0002-4061-4897]This book presents the results of the research project “Development of a warm asphalt mixture under technical and environmental criteria”, which was financed by the Scientific Research and Development Center (CIDC) of the Francisco José de Caldas District University. The study sought to develop an environmentally friendly asphalt mixture that would experience rheological, mechanical and durability properties similar to or superior to those of traditional asphalt concrete mixtures. For this purpose, the physical-mechanical and rheological response experienced by a warm asphalt mixture developed in the laboratory was evaluated, using a liquid chemical additive called HUSIL. This additive foams Colombian asphalt at temperatures close to 80°C, which allows the manufacturing temperature to be reduced and facilitates the coating of the asphalt with stone aggregates at lower temperatures. Within the document, the reader will find the conceptual framework and the state of knowledge on the topic of study, the methodology used during the execution of the project, the results and analysis of the study carried out, the conclusions and the bibliographic sources consulted and referenced.Ítem Modelo de asignación espectral multiusuario para redes de radio cognitiva descentralizadasHernández Suárez, César Augusto; Giral Ramírez, Diego Armando; Salgado Franco, Lizet CamilaThe growth of wireless applications poses new challenges to future communication systems, such as the inefficient use of the radio spectrum. Cognitive radio networks emerge as a solution to the problems of spectrum scarcity and inefficient use of the spectral resource, through dynamic access to the spectrum. These networks are characterized by perceiving, learning, planning (decision making), and acting according to current network conditions. The general objective of a cognitive radio network is for the secondary user to timely access an available frequency channel in a licensed band, without generating interference to the primary user, which can be achieved with adequate spectral decision making. The probability that two or more secondary users will choose the same channel is high, especially when the number of secondary users is greater than the number of available channels, and the more secondary users select the same channel, the lower the utility each can obtain and the number of interferences due to simultaneous access will be greater. The challenge then consists of providing the nodes of a decentralized network with the ability to learn from the environment, proposing strategies that allow secondary users to make decisions and exchange information cooperatively or competitively, in an environment of multi-user access to the spectrum. Likewise, this book seeks to resolve the question: how and to what extent can the spectral handoff rate be reduced in decentralized cognitive radio networks with a multi-user and collaborative approach?Ítem Memorias encontradas. ¿Qué piensan los estudiantes del conflicto armado?Arias Gómez, Diego Hernán; Arias Gómez, Diego Hernán [0000-0002-0116-0896]This text puts on the table the memories of the young students of Bogotá and their recognition of the social and political problems that the Colombian armed conflict has unleashed, while highlighting how other explanatory factors regarding its persistence are blurred. It shows the connections between these representations of the past, the frustrations of the present and the despair regarding the future that, sometimes, young people experience as an inescapable condemnation. The author shows us the 'found memories', those that he found and those that are found; those that approach and distance themselves. He reveals to us the 'fights for memory', 'the work of memory', 'the struggles for the past'. He tells us that there is not only one hegemonic memory. He warns us that young people also manifest how social memory frameworks operate by exposing memories that do not escape the social circulation of various memories. He reminds us that memories are never purely individual. He brings to the surface words and images but also silences and omissions.
