Secure Grid Services Over 4G Networks
The coming era of 4th generation networks is foreseeing a potential smooth merging of multiple heterogeneous technologies. A 4G network is characterized by the integration and the convergence of all communication networks, which are intrinsically diverse, heterogeneous, and dynamic, into one network. The main challenges raised by this network are the guarantee of seamless global roaming, the provision of cost-effective high data rates, the de finition of effi cient user-centric customized service models, and the optimization of the quality of service provision. Grid computing constitutes a promising alternative to guarantee secure service provision over 4G infrastructures.

This talk articulates around four major axes:

  • The architecture of a Grid-based service provision framework over a 4G communication infrastructure
  • The security services that should be guaranteed by the Grid service providers (authentication and identity management are at the heart of these services)
  • The payment models that should be supported to build up an accounting framework for the service provision infrastructure
  • The extension of the infrastructure to cloud computing, which is becoming a major concern in modern networks

Digital Virtual Characters in Urban Environments: Trends and Applications

Urban Computing is an emerging field of research aimed at studying the interactions between humans and urban environments and their cultural and social impact on the city. As such, it is a cross-disciplinary field that combines computer science, technology and research on human-computer interactions (HCI) with (among others) art, design, architecture and urban studies. One of the most popular issues in urban computing concerns the use of digital virtual characters resembling human beings and evolving into computer-generated urban environments. The increasing popularity of this topic can be largely explained by the fact that synthetic actors provide an excellent benchmark for the analysis and evaluation of different urban computing approaches and methodologies. In fact, they are increasingly being considered as a powerful computational tool in many urban scenarios. A typical example is given by virtual crowd simulations in applications ranging from site planning, education, training, and human factors analysis for building evacuation to simulations of public scenarios where masses of people gather, ?ow, and disperse, such as transportation centers, sporting events, and concerts. This talk explores this issue by presenting some of the most interesting developments in the field. Some recent trends and applications regarding this exciting field of reseach are also outlined.

From Rehabilitation to Personal Autonomy: advanced services in a Smart Grid Environment 

The talk will illustrate how the Information Technology is already able to impact the social life when the user is living in technologically advanced Urban environments and Smart Grid environments. Since even elderly persons are nowadays acquainted with the technology, we have some instruments (e.g.: early warnings) that may prevent problems and accidents and may help people with disabilities to increase their quality of life, up to reach the personal autonomy.

In this context the rehabilitation process could be limited in time, since with some sensors (simplified tracking systems, RFID systems, Beacon systems, etc) the user may be helped to progressively recover all social connections, her/his activity could be monitored in order to prevent accidents, some ad-hoc messages can be delivered using diverse channels (voice, video, text) to help the patient in problematic situations.

A various set of services may be activated to help the mobility of patients, the promotion and maintenance of social connections, the execution of specific tasks.

The named approach is able to reduce the rehabilitation costs and increase significantly the quality of live of patients.

Artificial Intelligence in SmartGrids 

The Smart Grid concept is being used in the context of power systems for some years and has gained importance with relevant research activities and manufacturer’s and political attention. Although the term is not new, there is not yet a generalized agreement about its meaning. The fact that a Smart Grid should be better equipped than present electrical grids providing the means to better operation and control seems, at first sight, the only common characteristic on which everyone seems to agree.

With several prototypes being on the way, all around the world, and relevant diverse funding opportunities that are available, it seems urgent to define exactly what the term Smart Grid applies to and what are the important limitations of the work developed so far.
The last decade has seen important steps forward in the development of the smart grid and microgrid concepts, as fundamental basis for intensively using renewables in an intelligent way. Implementation of these concepts has just beginning but the already obtained results show that success is reachable.

However, this is not sufficient to give answer to the above referred problems because it does not consider the needs of the involved players to operate in such a complex environment of dynamic and competitive nature. Available solutions are not capable or efficient at managing both commercial relationships and technical restrictions in a general way. On the contrary, they are focused on specific, relatively small problems. This results in a huge number of methods and regulations with focused/limited application that make the evolution from the present state to the future power systems with intensive use of DG highly difficult.

Moreover, artificial intelligence based methodologies and applications have not yet been able to give the relevant contribution they are expected for the practical implementation of the smart grid concept.

Distribution system reconfiguration methodology for SCADA application including Distributed Generation

Distributed energy resources (DER) have been receiving increasing attention as alternatives to centralized energy. It has been recognized as a good option for future energy system with respect to sustainable development and low-carbon society construction. A key resource to increase generation efficiency and reduce the greenhouse gas emission with respect to conventional separate production means, the small-scale distributed generation resources may be an attractive alternative in this sense. Thus, developing more DER can cut down on construction projects of large power generating plants and transmission lines. Use on-site generation may be an attractive alternative, since it alleviates the need for building the costly transmission grid. Moreover, a microgrid can play significant role to enhance local reliability, reduce feeder losses, support local voltages, voltage sag correction, or provide uninterruptible power supply functions.

This work presents a new and efficient methodology for distribution network reconfiguration in presence of DER integrated with optimal power flow (OPF) based on a Benders decomposition approach. The objective minimizes power losses, load balancing among feeders, and is subject to all technical constraints: capacity limit of branches, minimum and maximum power limits of substations or distributed generators, minimum deviation of bus voltages, and radial optimal operation of networks.

The ROPF problem addressed in this work is formulated as an MINLP problem with a nonlinear objective function, binary decision variables, continuous variables for operation processes, and nonlinear constraints, such as complete power-flow equations or distribution-lines capacity limits. The difficulties related to solving nonlinear optimization problems with binary variables force us to make use of partitioning techniques, such as the Benders decomposition. The Benders partition algorithm is a decomposition technique on two levels—master and slave—which defines an iterative procedure between both levels in order to reach the joint optimal solution.

The formulation can be embedded under two stages: the first one is the Master problem and is formulated as a mixed integer nonlinear programming problem. This stage determines the radial topology of the distribution network. The second stage is the Slave problem and is formulated as a nonlinear programming problem. This stage is used to determine the feasibility of the Master problem solution by means of an OPF and provides information to formulate the linear Benders cuts that connect both problems.

The effectiveness of the proposed model is demonstrated through examples extracted from the literature and the real world case.

Considering Emotions, Mood and Personality in Ambient Intelligence and Smart Environments

Traditionally, emotions and affects have been separated from cognitive and rational thinking; they have a bad connotation on what is related to the individuals’ behaviour, in particular on what is related to the decision-making process. However, in the last years, researchers from several distinct areas (psychology, neuroscience, philosophy, etc) have begun to explore the role of the emotion as a positive influence on human decision making process. Current research in Artificial Intelligence demonstrates also a growing interest in emotional agents. From human-computer interaction, to development of believable agents to the entertainment industry, and to modelling and simulating the human behaviour, there are a wide variety of application areas of emotional agents.

In this talk I will focus on the role of emotion, mood, and personality in the development of Ambient Intelligence systems and Smart Environments.

Biologically inspired information systems and secret data management

New generation information systems are developing rapidly due to the use of the latest achievements of cognitive informatics and biologically-inspired algorithmic techniques. Intelligent data analysis methods have recently become extremely significant in such systems in the context of searching for various information, collecting it and also enabling its meaning to be interpreted. What is also important in such solutions are techniques for the correct sharing of sensitive data and its subsequent intelligent management or distribution. There is no doubt that all these methods will become even more important in the near future because of the very dynamic development of Ambient Intelligence.

In the light of the above, in this talk I’ll present the opportunities for developing modern, new generation information systems based on cognitive models of semantic reasoning. Such models can be used, for instance, to interpret the meaning of image patterns. In this lecture I’ll also discuss methods of using biological information recording models, including DNA coding, to develop new classes of secret information sharing algorithms which can be deployed to manage data in various information structures.

Contexts and Security in Intelligent Urban Computing

Ambient Intelligence is an electronic environment that is sensitive and responsive to the presence of people. It is a vision on the future of consumer electronics, telecommunications and computing. An application skill which has ambient intelligence computing depends on the relativity of user and service. It is correlated with information expression and knowledge expression to disclose the real world state. There are various context and services contiguous to user’s environment. For user, it is transmitted on to devices such as PDA, mobile phone, laptop etc. and services gets a foundation from the server information near the user in a network environment.

ISyRA had been defined based on those context fom Ambient Intelligence system developments. ISyRAmI (Intelligent Systems Research for Ambient Intelligence) proposed by IST is an artificial intelligence oriented methodology and architecture for the development of ambient intelligence (AmI) systems. The ISyRAmI architecture considers the following four modules: Data/Information/Knowledge acquisition; Data/Information/Knowledge storage, conversion, and handling; Intelligent Reasoning; and Decision Support/Intelligent Actuation. Dr. Hoon Ko had presented the ISyRAmI SF, which deliberated security model to ISyRAmI in 2009, ISyRAmI is consists of four modules, context allocator, context analyzer, context collector and context detector.

Privacy in a ubiquitous networked world

The notion of computing has changed dramatically in the last few years. We now compute where we are, when it is needed, and with what we have. In addition we have seen a surge in the use of network applications such as social networking technologies. Today, we need to use our information in real-time, so we have augmented workstation-computing systems with wide variety of devices which includes lightweight ubiquitous devices such as smart phones, PDAs, personal tablets/pads, sensors, auto-id systems(RFID), and many others. Common characterizations of these devices are that they are mobile, wireless, pervasive, and they can quickly be launched and/or initialized to act on behalf of an owner/user. In such situations the privacy and integrity of the device is important to the owner/user. A question that arises is what privacy will be in a ubiquitous computing world. Issues will surface due to this “everywhere connectivity”.

In this talk we discuss privacy in this ubiquitous networked world. In particular, we will discuss the impacts that these mobile devices and networked technologies have on privacy and integrity. We discuss a set of general security requirements that should be satisfied in this ubiquitous world.
