This paper is concerned with the distance characteristics of terrestrial propagation as well as the optimal allocation of base stations (BSs) in complicated propagation environments. First, we review 1-ray and 2-rays models to simulate terrestrial electromagnetic wave propagations by introducing amplitude modification factor and propagation order of distance (β). Second, we propose an algorithm to determine the propagation parameters based on the Hata's empirical equations for introducing the communication distance function to estimate wireless accessibility. Finally, based on the particle swarm optimization (PSO), we propose an adaptive algorithm for generating inhomogeneous triangular cells to optimally allocate BSs.

Collaborative and social learning assessment requires a broad perspective about learning and the involved processes. Assessment processes have a significant effect on CSCL because they engage learners through accountability and constructive feedback. However, in order to design a coherent and efficient assessment system for collaborative and social learning it is necessary to design an enriched learning experience that predisposes the feedback and awareness in the group. A complex set of simultaneously applied assessment approaches, each reinforcing and/or complementing the other is the main tool to enhance collaborative learning and social interaction amongst group members. In this paper, collaborative learning will be developed into a special environment: a Storyboard Learning Object. Collaborative learning using a storyboard may develop partners' collaborative and social abilities and competences through a sequential of integrated process where the interaction moves are continuously evaluated to determine the storyboard sequence and the use of the resources. To this end, two levels of assessment are proposed: deferred and immediate. Both are combined with contextual information about the user in order to produce an efficient and personalized assessment feedback to ultimately enhance and improve the collaborative learning experience. The research reported in this paper is currently undertaken within a FP7 European project called ALICE.

Around Device Interaction (ADI) is recently introduced in the field of Human Computer Interaction (HCI)to provide touch less, more intuitive way of interaction using space beyond the physical boundary of the computing devices. In this paper, we introduce a new ADI input device called Pingu in the form factor of a fingering that allows users to interact with any nearby computing device with wireless connectivity in a ubiquitous environment. Fingering form factor is chosen for our prototype design, as it is socially acceptable and is commonly worn in everyday social contexts, and based on the previous research, the information entropy of interaction by fingers is greater than the entropy for any other parts of the human body. The current Pingu prototype is consisted of an extensive set of sensors, visual and vibrot actile feedback mechanisms with wireless connectivity that make it a unique input device for human-computer or human-human interaction in the form of gestures, tactile and touch. Its usage can range from advanced, tiny and novel gestural interaction with a variety of devices to mobile and networked sensing, and social computing. We present a few potential applications of Pingu such as social interaction, context recognition, in-car interaction, and physical activity analysis.

The problem of implementing socially intelligent agents has been widely investigated in the field of both Embodied Conversational Agents (ECAs) and Social Robots that have the advantage of offering to people the possibility to relate with computer media at a social level. We focus our study on the recognition of the social response of users to embodied agents in the context of ambient intelligence. In this paper we describe how we extended a model for recognizing the social attitude in natural conversation from text by adding two additional knowledge sources: speech and gestures.

The electric power consumption of servers has to be reduced in information systems in addition to increasing the performance and fault-tolerancy in order to realize green societies. In information systems, servers mainly consume the electric power to perform processes requested by clients. We consider computation (CP) and storage (ST) types of application processes to be performed on servers. In CP processes, CPU resource is mainly consumed. In st processes, storage drives are manipulated in a server. First, we present the storage-based power consumption (SBPC) model of a server st to perform st and CP processes. The SBPC model is a four-state model, where the power consumption rate of the server is one of four rates minEt, maxSTt, maxCt, and maxSTCt. Here, the power consumption rate Et(τ) of a server st of time τ is minimum minEt if no process is performed. Et(τ) the power consumption rate is maxSTt if only and at least one ST process is performed. Et(τ) is maxCt if only and at least one CP process is performed on the server st. If both ST and CP processes are performed, Et(τ) is maxSTCt. Here, minEt <; maxSTt <; maxCt <; maxSTCt. According to the SBPC model, it is better not to perform both ST and CP processes on a same server because the maximum power is consumed in the server. By using the SBPC model, we discuss an algorithm for selecting a server so that not only the execution time but also the power consumption can be reduced. In the algorithm, ST and CP processes are tried to be performed on different servers.

Virtual Organizations are a specific type of Multi-Agent Systems that look for modeling agent organizations by means of elements typically used in Organizational Theory, such as roles, organizational goals, or services. The Organizational Theory considers that the structure of a human organization is likely to change through time, being the external and internal forces that drive organizational change the most important source for change. This work presents a set of guidelines that will help MAS designers and developers how to deal with these forces, in order to take advantage of them, or to avoid damage to the organization.

In pervasive computing environments the availability of real-time computation models is expected to predict a performance of Tunnel Boring Machine (TBM). Context awareness allows an entity adapt to uncertain environment, offering a number of intelligent prediction methods for tunneling. This study presents a proposal of a Context-Aware Tunneling System using Hybrid Artificial Neural Networks for prediction of TBM performance and risk response in uncertain geological environments. The proposed approach is essential to predict the TBM performance, together warning disaster risks in terms of the performance and risk response for the planning projects of tunneling. In addition, the proposed approach aims to predict TBM performance and utilization through a network in complex underground conditions such as rock mass, geology, lithography, and disaster in tunnel projects. The proposed approach has tested in experiments using data series from tunnel projects in Japan and Asian countries. To validate the significance of the findings and show added valuable parameters of the proposed approach, the results are compared with conventional statistical methods in terms of TBM performance evaluation. In order to evaluate the effectiveness of this approach, experimental results show that the proposed approach performs better than other current methods under uncertain geological environments.

The objective of this work is to suggest criteria and guidelines that can be used to design inclusive technological solutions to support human activity sharing in the context of Ambient Intelligence. These guidelines derive from the analysis of previous works in related fields such as cognitive engineering, usability, inclusive design and accessibility. The first step of this work was the definition of a number of principles that enable humans to interact with the environment and with other people through the environment. Each principle is further defined by a number of guidelines that more concretely explain how to satisfy it. The modular organization of the guidelines enables them to be applied for two purposes: the first six principles can be used to guide the design of a generic inclusive Ambient Intelligence system, all together are specifically oriented to the design of human activity sharing systems.
