The Internet is evolving to accommodate users' demands, including mobility (users are mobile) and ubiquitous connectivity (billions of devices demand IP connectivity). The former has caused the design of IP mobility protocols aimed at enabling terminals to seamlessly roam among heterogeneous access networks, while the latter has speeded up the depletion of the IPv4 addressing space, triggering the design of a new version of IP (IPv6) and the development of transition mechanisms to enable the coexistence of IPv4-and IPv6-based networks. During the transition period, which is expected to last years, dual stack IPv4 and IPv6 mobile nodes will roam across IPv4-and-IPv6, IPv6-only and IPv4-only networks. This article presents a comprehensive tutorial of the mechanisms that have been standardized recently to support dual stack IP mobility management. © 2002-2012 IEEE.

The development of new technology is driven by scientific research The Internet, with its roots in the ARPANET and NSFNet, is no exception Many of the fundamental, long-term improvements to the architecture, security, end-to-end protocols and management of the Internet originate in the related academic research communities Even shorter-term, more commercially driven extensions are oftentimes derived from academic research When interoperability is required, the IETF standardizes such new technology Timely and relevant standardization benefits from continuous input and review from the academic research community For an individual researcher, it can however by quite puzzling how to begin to most effectively participate in the IETF and - arguably to a much lesser degree - in the IRTF The interactions in the IETF are much different than those in academic conferences, and effective participation follows different rules The goal of this document is to highlight such differences and provide a rough guideline that will hopefully enable researchers new to the IETF to become successful contributors more quickly.

One of the grand challenges for the robotics community is to create robots that operate robustly in realworld scenarios. Most current robots are limited to factories, laboratories or similar controlled settings. This contrasts with the seeming ease with which insects, animals and humans handle uncertainty, dynamic events and complexity. Assistive robots are for example being envisioned for aiding elderly and disabled persons in their homes. A key skill for these robots will be to operate in, and physically manipulate, daily life environments. However, it is unclear how to achieve this while complying with the safety and reliability requirements of such devices. Distributed Adaptive Control (DAC) is an example of a biologically inspired architecture for control and adaptation, where the lowest unit is the reflex. We here explore recent work on extending this idea to shared control of assistive robot manipulators. That is, where sensing, learning and control are distributed throughout the system, and across both user and robot. We show that such a distributed approach can reduce the need for central information processing, exact internal representations, and 'global' approaches to learning in the robot. The reduced algorithmic complexity can help increase the robustness and usability of the system on real-world tasks. © 2014 IEEE.
The study, published in the latest issue of the journal Science Advances, along with scientists from NICTA (National Information Communications Technology Australia) and the University of California in San Diego concludes that it is possible to determine the damage caused by a natural disaster in just a few hours, by using data from social networks. "Twitter, the social network which we have analyzed, is useful for the management, real-time monitoring and even prediction of the economic impact that disasters like Hurricane Sandy can have," says one of the researchers, Esteban Moro Egido, of UC3M's Grupo Interdisciplinar de Sistemas Complejos - Complex Systems Interdisciplinary Group (GISC). The research was carried out by analyzing Twitter activity before, during and after Hurricane Sandy which, in 2012, caused more damage than any other storm in US history, with an economic impact in the region of 50,000 million dollars. Hundreds of millions of geo-located tweets making reference to this topic were collected from fifty metropolitan areas in the USA. "Given that citizens were turning to these platforms for communication and information related to the disaster, we established a strong correlation between the route of the hurricane and activity on social networks," explains Esteban Moro. But the main conclusion of the study was obtained when the data relating to social network activity was examined alongside data relating to both the levels of aid granted by the Federal Emergency Management Agency (FEMA) and insurance claims: there is a correlation between the mean per capita of social network activity and economic damage per capita caused by these disasters in the areas where such activity occurs. In other words, both real and perceived threats, along with the economic effects of physical disasters, are directly observable through the strength and composition of the flow of messages from Twitter. Furthermore, researchers have verified the results obtained from Hurricane Sandy and have been able to demonstrate that the same dynamic also occurs in the case of floods, storms and tornadoes; for example, whenever there is sufficient activity on social media to extract such data. In this way, communication on Twitter allows the economic impact of a natural disaster in the affected areas to be monitored in real time, making it possible to provide information in addition to that currently used to assess damage resulting from these disasters. Moreover, the distribution space of the event-related messages can also help the authorities in the monitoring and evaluation of emergencies, in order to improve responses to natural disasters. The authors of the study suggest that we are facing an increase in the frequency and intensity of natural disasters as a consequence of climate change. "We believe that this is going to cause even more natural disasters and, therefore, the use of social networks will allow us to obtain useful supplementary information," points out Professor Esteban Moro, who is currently working on further research in this area. "We are trying to see if there is a relationship between activity on social networks and climate change which will affect us in the future".

A new concept for an ergonomic smart desk with the objective of improving teamwork, this proposal has been put forward by Pynk Systems, a company created by an entrepreneur from the UC3M Science Park Business Incubator. Credit: uc3m New technologies are changing the way people work; in recent years, many companies have tended towards using large open plan spaces, without individual offices, which help to facilitate teamwork. With this in mind, Pynk Systems is launching a new work concept called the "Ergon Desk". This smart desk has an ergonomic design incorporating movable elements, which can be adapted to both laptops and tablets; it is controlled by an application. "At the start of the working day, we will be able to log-in at our work stations and the desk will respond by recognizing our work configurations, our height, both seated and standing, and our preferences for the desk's degree of inclination", explains David Mata, Pynk Systems' CEO. Each desk can be operated by foot and is equipped with sensors which are able to learn from user behavior patterns and, therefore, recommend posture changes and rest breaks based on the ergonomic criteria that best suits the user's way of working. David Mata goes on to point out that "there are around thirty five medical conditions associated with the sedentary nature of desk jobs, and the Ergon Desk helps to minimize these ailments as well as increasing productivity during the working day". According to the creators, the ergonomic design of each work station optimizes office space by offering the same work area, but taking up thirty percent less space than a conventional distribution. Pink Systems' CEO adds, "Entering the UC3M Scientific Park has been instrumental not only in supporting us in the design of the product and the incorporation of the most advanced technologies, but also in publicizing its launch."
