The arrival of telegraphy and railroads changed power relations throughout the world in the nineteenth century. In the Mesilla region of the American Southwest, it contributed to two distinct and rapid shifts in political and economic power from the 1850s to the 1920s. Torsten Kathke illustrates how the changes these technologies wrought everywhere could be seen at a much accelerated pace here. A local Hispano elite was replaced first by a Hispano-Anglo one, and finally a nationally oriented Anglo elite. As various groups tried to gain, hold, and defend power, the region became bound ever closer to the US economy and to the federal government.
Die Effizienzsteigerung im Bauwesen steht definitiv im Umgang mit den Datenmodellen im Zusammenhang. Anforderung und Umsetzung von modellorientierter digitaler Planung werden in Zukunft die Erfolge von Projekten bestimmen.

Wie kann man Informationen in Planungsunterlagen so hinterlegen, dass sie in sp teren Prozessschritten einen Mehrwert erzeugen, was muss man beachten um Verkn pfungen zu erm glichen, welche Technologien stehen heute schon bereit...
Mobile multi-robot systems may be deployed in environments initially unknown to them. Their efficient operation requires detailed maps of their surroundings. The robot system charts the environment during initial exploration. Multiple robots collaborate to speed up the exploration by distributing the exploration area. They form a mobile ad hoc network enabling coordination and the exchange of map information. The multi-robot system described herein is fully self-organizing. It does not rely on a central controller increasing scalability and robustness. Scalability allows deployments in large environments such as industry complexes or ramified cave systems. The performance of the system, determined by the time required to fully explore an environment, benefits from integration of additional explorers. By allowing a fully connected robot system to split into multiple independently operating teams, robots may cover larger areas more quickly. Two forms to establish connectivity are discussed: robots may serve as stationary relays forming a multi-hop network. Alternatively, relay robots may carry data between communication end-points freeing robots to support exploration.
