This paper presents an analysis using hierarchical grouping method (ward grouping) and the non-hierarchical grouping method (k-means) to analyze the participation levels in activities and interactions in a virtual forum. Data came from a MOOC and it was on grammatical rules of Brazilian Portuguese. About 5100 participants integrated the course. It lasted about three months and the activities developed...
This paper describes the result of the work started in the first Cloud Computing session in WETICE 2009. During the last seven years, collaboration from participants in WETICE has resulted in a new computation model and a commercial product that advances the state of the art in infrastructure agnostic distributed application life-cycle quality of service management. In WETICE 2016, celebrating its...
The System development projects continue to fail at unacceptable rates. Including a wide array of users in the requirements development process for a wide-audience system can help to increase system success. Facilitated group workshops can effectively and efficiently gather requirements from several different users. To decrease cost and increase the number of potential workshop participants, we designed...
Teachers need relevant information about learners' activities in order to regulate these activities. In addition, they also have to manage their own work especially their interventions. To do that, they need information about the real impact of their actions, especially their interventions, in order to adjust their behavior and strategies. In this paper, we propose an indicator-based approach to supply...
In single-piece and small-batch production enterprise, the product manufacturing process often needs change and production scheduling problem is complicated. According to the development process of single-piece and small-batch product (SSP), a collaborative platform via network based manufacturing environment for SSP development is proposed in this paper. The main structure of the platform and the...
In this paper, we propose the use of an agent-based architecture to enhance workflow system capacity to support interprofessional, patient-centred palliative care delivery. This paper outlines the concept of palliative care and describes how agents can be used to assist care providers to address the needs of the patient and family. Our architecture is illustrated in a diagram and the agents are described...
This paper describes a free and open source information system designed to be deployed in emergencies caused by sudden onset natural disasters. The aim is to streamline the communication flow and collaboration between media, aid workers and government agencies with the affected population, to help the latter get verified, accurate and actionable information that will enable them to make decisions...
IT service providers face a great need to improve the quality of services by IT service management (ITSM) in highly complex IT Environments. This pressure demands a strong collaboration from both the external service providers and internal service providers. However, providers still lack the necessary support, in methodologies and tools, to achieve efficient collaboration strategies. This paper proposes...
We hypothesize that it is useful and possible to automatically identify that distributed programmers are stuck by extending existing software development environments using a general architecture.
Management of the northern Gulf of Mexico large hypoxic zone is driven primarily by the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force (?Hypoxia Task Force?) Action Plan. Both the 2001 and revised 2008 Action Plans called for a reduction in the average areal extent of the hypoxic zone to 5000 km2 by the year 2015, less than 1/3 the current typical annual maximum area. To achieve this...
Interpersonal communication is based on acoustical and visual information exchange. Videoconferencing systems allow the communication between people separated by large distances by recording acoustical as well as visual information. In this article, we present a multi person videoconferencing system integrated in an Augmented Reality framework. Existing Augmented Reality applications already support...
Policy-based management is typically used to manage large and complex systems, e.g. the management of telecommunications networks. When collaborating multi-disciplinary managers try to create policies from their own viewpoint they are hindered by a lack of a common vocabulary and an inability to understand how the complex system currently operates and how it is constrained. For example, modern telecoms...
Datasets of tens of gigabytes are becoming common in computational and experimental science. Providing remote visualization of these large datasets with adequate levels of quality and interactivity is an extremely challenging task, particularly for scientists who collaborate in widely distributed locations and their primary access to visualization resources is a desktop computer. This paper describes...
This short paper describes an innovative project-based learning experience for software engineering education and training. A global software development project is currently underway to unite students from across the globe, with widely different backgrounds and learning objectives, in distinct project roles that are designed to leverage skill sets and foster overall quality and success. The background...
The Open Distributed Processing Reference Model (ODP-RM) provides viewpoints and abstract infrastructure guidelines that can be used for a basis for enterprise architecture, especially for an inter-enterprise architecture. The ODP-RM does not prescribe methodology for modeling itself, but provides common vocabulary and focus for description. This paper performs a brief analysis of the ODP-RM (and...
Accelerated by the rapid deployment of distributed systems and the Internet, online collaboration and information sharing are pervasive in enterprise computing environment. With regard to the requirements of online collaboration and information sharing, authentication information needs flexible manipulation to facilitate federation across trust domains. To achieve identity federation for federated...
