The real-time city is now real! The increasing deployment of sensors and handheld electronic devices in recent years allows for a new approach to the study and exploration of the built environment. The WikiCity project deals with the development of real-time, location-sensitive tools for the city and is concerned with the real-time mapping of city dynamics. This mapping, however, is not limited to representing the city, but also instantly becomes an instrument for city inhabitants to base their actions and decisions upon in a better informed manner, leading to an overall increased efficiency and sustainability in making use of the city environment. While our comprehensive research program considers a larger context, this chapter discusses the WikiCity Rome project, which was the first occasion for implementing some of WikiCity’s elements in a public interface—it was presented on a large screen in a public square in Rome.

This paper proposes a method of assigning trips to automated taxis (ATs) and designing the routes of those vehicles in an urban road network, and also considering the traffic congestion caused by this dynamic responsive service. The system is envisioned to provide a seamless door-to-door service within a city area for all passenger origins and destinations. An integer programming model is proposed to define the routing of the vehicles according to a profit maximization function, depending on the dynamic travel times, which varies with the ATs’ flow. This will be especially important when the number of automated vehicles (AVs) circulating on the roads is high enough that their routing will cause delays. This system should be able to serve not only the reserved travel requests, but also some real-time requests. A rolling horizon scheme is used to divide one day into several periods in which both the real-time and the booked demand will be considered together. The model was applied to the real size case study city of Delft, the Netherlands. The results allow assessing of the impact of the ATs movements on traffic congestion and the profitability of the system. From this case-study, it is possible to conclude that taking into account the effect of the vehicle flows on travel time leads to changes in the system profit, the satisfied percentage and the driving distance of the vehicles, which highlights the importance of this type of model in the assessment of the operational effects of ATs in the future.

The out-of-step protection function is one of the key functions in generator protection. This function detects the loss of generator synchronism, and when such a fault occurs, it is necessary to disconnect the generator from the rest of the system as soon as possible in order to avoid major damages.The algorithms used in the out-of-step protection functions are based on the measurements of generator impedances and they use the impedance vectors to check if all stability criterions are met. This paper describes a new approach to realizing the out-of-step generator protection function by using the direct load angle measurement. The idea behind applying the real time load angle measurement is to faster detect the loss of synchronism.

This chapter describes a participatory design experiment that is influenced by the swarming activity. The chapter introduces a new approach to writing narratives in virtual learning communities of the social Web 2.0 and contrasts it with traditional storytelling approaches. In the participatory design experiment we developed a hybrid virtual storytelling playground that augments the real world – a hybrid ecosystem of narratives. It consists of social software tools freely available in the Web, such as microblogs, social repositories of images, and blogs, the real locations in the city, and the storytellers who leave their digital contents. The results of writing narratives as a swarm in a hybrid ecosystem are presented. In our experiment, instead of bending old novel formats into the hybrid ecosystem, the evidences of new evolving narrative formats of this hybrid space were explored.
