It is usual that existing material on computer aided geometric design oscillates between over-simplification for programmers and practitioners and over formalism for scientific or academic readers. The first type of publications suppresses the taxonomy and properties of the mathematical concepts discussed when seeking straightforward notation and procedures. The second type of materials in thorough in the mathematical concepts at the expense of increasingly complicated notation and sacrifice of clear procedures for the reader.This book intends to be a compromise between the aforementioned extremes. It recalls basic concepts on functions, relations, transformations, matrices and groups and ma...
This volume constitutes the refereed proceedings of the 8th Workshop on Engineering Applications, WEA 2021, held in Medellín, Colombia, in October 2021. Due to the COVID-19 pandemic the conference was held in a hybrid mode. The 33 revised full papers and 11 short papers presented in this volume were carefully reviewed and selected from 127 submissions. The papers are organized in the following topical sections: computational intelligence; bioengineering; Internet of Things (IoT); optimization and operations research; engineering applications.
The work of geotechnical engineers contributes to the creation of safe, economic and pleasant spaces to live, work and relax all over the world. Advances are constantly being made, and the expertise of the profession becomes ever more important with the increased pressure on space and resources. This book presents the proceedings of the 15th Pan-American Conference on Soil Mechanics and Geotechnical Engineering (XV PCSMGE), held in Buenos Aires, Argentina, in November 2015. This conference, held every four years, is an important opportunity for international experts, researchers, academics, professionals and geo-engineering companies to meet and exchange ideas and research findings in the ar...
Drug Trafficking, Corruption and States is cutting edge research. Garay Salamanca and Salcedo-Albarán, along with their contributing authors help document the transition from economic to political imperatives within transnational drug cartels. The break from the Zetas by La Familia Michoacana is one example contained in their empirical survey. Social Network Analysis is their tool for illuminating the varying dynamics of cartel-state inter-penetration and reconfiguration. In doing so they clearly discern between State Capture (StC) and Co-opted State Reconfiguration (CStR). As the drug wars and criminal insurgencies rage in the Americas and beyond, this seminal framework will facilitate efforts by scholars, law enforcement officials, intelligence analysts and policymakers to understand shifts in sovereignty, and to illuminate the mechanisms of transnational illicit networks and their interaction with the state.
This volume aims to familiarize readers with the varieties of world Englishes used across cultures and to create awareness of some of the linguistic and socially relevant contexts and functions that have given rise to them. It emphasizes that effective communication among users of different Englishes requires awareness of the varieties in use and their cultural, social, and ideational functions. Cultures, Contexts and World Englishes: demonstrates the rich results of integrating theory, methodology and application features critical and detailed discussion of the sociolinguistics of English in the globalized world gives equal emphasis to grammar and pragmatics of variation and to uses of Englishes in spoken and written modes in major English-using regions of the world. Each chapter includes suggestions for further reading and challenging discussion questions and appropriate research projects designed to enhance the usefulness of this volume in courses such as world Englishes, English in the Global Context, Sociolinguistics, Critical Applied Linguistics, Language Contact and Convergence, Ethnography of Communication, and Crosscultural Communication.
Marta Traba, one of Latin America's most controversial art critics, examines the works of over 1,000 artists from the first 80 years of the 20th century. This book is an indispensable reference for anyone interested in studying the evolution of Latin American art.
This book is composed by the papers accepted for presentation and discussion at The 2019 International Conference on Information Technology & Systems (ICITS'20), held at the Universidad Distrital Francisco José de Caldas, in Bogotá, Colombia, on 5th to 7th February 2020. ICIST is a global forum for researchers and practitioners to present and discuss recent findings and innovations, current trends, professional experiences and challenges of modern information technology and systems research, together with their technological development and applications. The main topics covered are: information and knowledge management; organizational models and information systems; software and systems modelling; software systems, architectures, applications and tools; multimedia systems and applications; computer networks, mobility and pervasive systems; intelligent and decision support systems; big data analytics and applications; human–computer interaction; ethics, computers & security; health informatics; information technologies in education.
Colombia's status as the fourth largest nation in Latin America and third most populous—as well as its largest exporter of such disparate commodities as emeralds, books, processed cocaine, and cut flowers—makes this, the first history of Colombia written in English, a much-needed book. It tells the remarkable story of a country that has consistently defied modern Latin American stereotypes—a country where military dictators are virtually unknown, where the political left is congenitally weak, and where urbanization and industrialization have spawned no lasting populist movement. There is more to Colombia than the drug trafficking and violence that have recently gripped the world's atte...
