While substantial effort has been devoted to understand fraudulent activity in traditional online advertising (search and banner), more recent forms such as video ads have received little attention.

Mobile robots collaborate in order to solve efficiently the central problems in algorithmics of distributed computing like searching/exploration, rendez-vous or pattern formation.

The Internet is an evolving ecosystem where a multitude of interconnected networks, or Autonomous Systems (ASes), support global connectivity of end users. 

Imagine a network in which you address information: literally, packet-level addressing of *information* rather than hosts. For example, you may request the front page of El País with a request packet addressed to "the front page of El País"! Then the network forwards the request to some server that can produce the right data (possibly cached) and then delivers that data back to you. You don't have to figure out where that information is; the network does that for you.

Middleboxes, such as proxies, firewalls and NATs play an important role in the modern Internet ecosystem. On one hand, they perform advanced functions, e.g. traffic shaping, security or enhancing application performance.

The impact of car accidents in human lives calls for a profound understanding of accident risk. However, the unpredictability of accidents and the unfeasibility of their reproduction make it difficult to identify the causes and patterns underlying individual accidents.

In a multi-channel wireless network, each node is able to use multiple non-overlapping frequency channels, by having more network interface cards.

The rising number of mobile devices and their increasing computational capabilities enable new interactive context-sensitive applications.

We have experienced an era in the world of innovation where the stars have been the entrepreneurs. Small startups or even individuals were able to turn their ideas into big business and, in many cases, overcome large companies with a long tradition in the market.

Big Data and Cloud Computing are two paradigms that are evolving hand in hand and are revolutionizing how we live and work. The amount of data that is being generated in the world is increasing every day, and there are no indications that this trend is going to stop any time soon (if ever).
