This paper introduces Geo-Mobile Query-by-Sketch, a sketch-based spatial querying system for mobile GIS environments that combines techniques for spatial querying with mobile technologies. The system implements an adaptive client-server architecture, which copes with restrictions of mobile environments, such as fluctuating bandwidth and frequent disconnections. The core concept analyzed is the mobile sketch, a multi-representation data structure of a sketched scene, which enables an adaptation strategy that is tailored to the available transmission rates. We analyze the transmission cost of Geo-Mobile Query-by-Sketch and develop a protocol that optimizes the adaptation level in order to guarantee quality of service
What went wrong: Corona and the world after the full stop
No full textEste artículo examina la respuesta global a la pandemia de covid-19. Argumenta que es urgente ver más allá del virus para entender la verdadera gravedad de loque está sucediendo hoy. ¿Cómo terminamos en un espacio de pensamiento, acción y sentimiento que ha normalizado los extremos y se basa en el supuesto de que la vida biológica es un valor absoluto separado de la política? El autor sugiere que el temor actual es alimentado por los modelos matemáticos de la enfermedad, las políticas de salud neoliberales, los informes nerviosos de los medios y los anhelos autoritarios.This article examines the global response to the covid-19 pandemic. It argues that we urgently need to look beyond the virus if we want to understand the realseriousness of what is happening today. How did we end up in a space of thinking, acting, and feeling that has normalized extremes and is based on the assumption that biological life is an absolute value separate from politics? The author suggests that today’s fear is fueled by mathematical disease modeling, neoliberal health policies, nervous media reporting, and authoritarian longings

Ele argumenta que é urgente olhar além do vírus para entender a verdadeira gravidade do que estáacontecendo hoje. Como acabamos em um espaço de pensamento, ação e sentimento que normalizou os extremos e se baseia no pressuposto de que a vida biológica é um valor absoluto separado da política? O autor sugere que o medo atual é alimentado por modelos matemáticos da doença, políticas de saúde neoliberais, relatórios nervosos da mídia e anseios autoritários
