Supporting service discovery, querying and interaction in ubiquitous computing environments.

In this paper, we contend that ubiquitous computing environments will be highly heterogeneous, service rich domains. Moreover, future applications will consequently be required to interact with multiple, specialised service location and interaction protocols simultaneously. We argue that existing service discovery techniques do not provide sufficient support to address the challenges of building applications targeted to these emerging environments. This paper makes a number of contributions. Firstly, using a set of short ubiquitous computing scenarios we identify several key limitations of existing service discovery approaches that reduce their ability to support ubiquitous computing applications. Secondly, we present a detailed analysis of requirements for providing effective support in this domain. Thirdly, we provide the design of a simple extensible meta-service discovery architecture that uses database techniques to unify service discovery protocols and addresses several of our key requirements. Lastly, we examine the lessons learnt through the development of a prototype implementation of our architecture

Building the Future Internet through FIRE

The Internet as we know it today is the result of a continuous activity for improving network communications, end user services, computational processes and also information technology infrastructures. The Internet has become a critical infrastructure for the human-being by offering complex networking services and end-user applications that all together have transformed all aspects, mainly economical, of our lives. Recently, with the advent of new paradigms and the progress in wireless technology, sensor networks and information systems and also the inexorable shift towards everything connected paradigm, first as known as the Internet of Things and lately envisioning into the Internet of Everything, a data-driven society has been created. In a data-driven society, productivity, knowledge, and experience are dependent on increasingly open, dynamic, interdependent and complex Internet services. The challenge for the Internet of the Future design is to build robust enabling technologies, implement and deploy adaptive systems, to create business opportunities considering increasing uncertainties and emergent systemic behaviors where humans and machines seamlessly cooperate

Survey and Analysis of Production Distributed Computing Infrastructures

This report has two objectives. First, we describe a set of the production distributed infrastructures currently available, so that the reader has a basic understanding of them. This includes explaining why each infrastructure was created and made available and how it has succeeded and failed. The set is not complete, but we believe it is representative. Second, we describe the infrastructures in terms of their use, which is a combination of how they were designed to be used and how users have found ways to use them. Applications are often designed and created with specific infrastructures in mind, with both an appreciation of the existing capabilities provided by those infrastructures and an anticipation of their future capabilities. Here, the infrastructures we discuss were often designed and created with specific applications in mind, or at least specific types of applications. The reader should understand how the interplay between the infrastructure providers and the users leads to such usages, which we call usage modalities. These usage modalities are really abstractions that exist between the infrastructures and the applications; they influence the infrastructures by representing the applications, and they influence the ap- plications by representing the infrastructures

Self-regulation and time factor in virtual and remote laboratories

In the field of practical development of competences in scientific and engineering studies, the emergence of distance learning programs in these disciplines, as well as the rapid development of ICT, has allowed the evolution of classical laboratories towards a new typology of laboratories: the commonly called virtual labs, focused on the development of simulation-based practices in both classroom or remote sessions and remote laboratories equipped with real equipment that are connected and accessible remotely, by providing the student a practical resource not defined in a specific space and time such as onsite laboratories.Currently extensive information on the different types of laboratories can be found; their structure, the tools that they use, the type of experiment performed, but there is less information about teaching and pedagogical application of these technologies. Factors like self-regulation, allowing a constructivist approach to training with these tools; the Time factor and assessment are subjects susceptible to be studied.Starting from the generic structure of remote laboratory, exposed in the first section, we will study how this structure can influence the factors under study: self-regulation and Time Factor, and how to approach this structure and the elements that make it up to improve these aspects

Collaborative Designing for Youth Wellbeing: The Story of Our Design Day

The Design Day brought together youth sector stakeholders – youth, youth workers, policy makers, researchers, funders and citizens – to collaboratively tackle four 'thorny' challenges, or Idea Labs, that youth and youth workers experience. This event was hosted in collaboration with the Youth Opportunities Fund at the Ontario Trillium Foundation. This report is a snapshot of this Design Day and includes the four Idea Lab challenges that the Design Day focused on, and the eight prototype pitches that participants co-developed in response to these challenges. The report includes reflections on the collaborative process along with resources and case study examples that can inspire our youth work.Idea Labs: 1) Bringing Our Whole Selves: Inclusive Programs With And For Racialized LGBTTQQ2SIA Youth; 2) Indigenizing Youth Work: Towards A New Relationship; 3) Far And Farther: Equitable Access To Programs, Services, And Opportunities For Youth Living In Rural And Remote Communities; 4) Beyond The Individual: Community / Collective Approaches To Youth Worker Wellbein

Evolution of the Air Toxics Under the Big Sky Program

As a yearlong exploration of air quality and its relation to respiratory health, the “Air Toxics Under the Big Sky” program offers opportunities for students to learn and apply science process skills through self-designed inquiry-based research projects conducted within their communities. The program follows a systematic scope and sequence designed to first lay a strong foundation, followed by activities intended to expand understanding, and ending with a final step aimed at achieving retention of content and principles learned. The foundation consists of content regarding environmental health sciences and human health. The next level guides students during their independent study projects as they test their hypotheses, analyze results, and draw conclusions. The final step requires these junior researchers to share their findings with others in some type of culminating event, with the most prominent being a high school symposium held at the conclusion of the school year. This article describes the evolution of the Air Toxics Under the Big Sky program since its inception in 2003

Enabling peer-to-peer remote experimentation in distributed online remote laboratories

Remote Access Laboratories (RALs) are online platforms that allow human user interaction with physical instruments over the Internet. Usually RALs follow a client-server paradigm. Dedicated providers create and maintain experiments and corresponding educational content. In contrast, this dissertation focuses on a Peer-to-Peer (P2P) service model for RALs where users are encouraged to host experiments at their location. This approach can be seen as an example of an Internet of Things (IoT) system. A set of smart devices work together providing a cyber-physical interface for users to run experiments remotely via the Internet. The majority of traditional RAL learning activities focus on undergraduate education where hands-on experience such as building experiments, is not a major focus. In contrast this work is motivated by the need to improve Science, Technology, Engineering and Mathematics (STEM) education for school-aged children. Here physically constructing experiments forms a substantial part of the learning experience. In the proposed approach, experiments can be designed with relatively simple components such as LEGO Mindstorms or Arduinos. The user interface can be programed using SNAP!, a graphical programming tool. While the motivation for the work is educational in nature, this thesis focuses on the technical details of experiment control in an opportunistic distributed environment. P2P RAL aims to enable any two random participants in the system - one in the role of maker creating and hosting an experiment and one in the role of learner using the experiment - to establish a communication session during which the learner runs the remote experiment through the Internet without requiring a centralized experiment or service provider. The makers need to have support to create the experiment according to a common web based programing interface. Thus, the P2P approach of RALs requires an architecture that provides a set of heterogeneous tools which can be used by makers to create a wide variety of experiments. The core contribution of this dissertation is an automaton-based model (twin finite state automata) of the controller units and the controller interface of an experiment. This enables the creation of experiments based on a common platform, both in terms of software and hardware. This architecture enables further development of algorithms for evaluating and supporting the performance of users which is demonstrated through a number of algorithms. It can also ensure the safety of instruments with intelligent tools. The proposed network architecture for P2P RALs is designed to minimise latency to improve user satisfaction and learning experience. As experiment availability is limited for this approach of RALs, novel scheduling strategies are proposed. Each of these contributions has been validated through either simulations, e.g. in case of network architecture and scheduling, or test-bed implementations, in case of the intelligent tools. Three example experiments are discussed along with users' feedback on their experience of creating an experiment and using others’ experimental setup. The focus of the thesis is mainly on the design and hosting of experiments and ensuring user accessibility to them. The main contributions of this thesis are in regards to machine learning and data mining techniques applied to IoT systems in order to realize the P2P RALs system. This research has shown that a P2P architecture of RALs can provide a wide variety of experimental setups in a modular environment with high scalability. It can potentially enhance the user-learning experience while aiding the makers of experiments. It presents new aspects of learning analytics mechanisms to monitor and support users while running experiments, thus lending itself to further research. The proposed mathematical models are also applicable to other Internet of Things applications
