Abstract

The IMS networks (IP Multimedia Subsystem) allow the telecommunications networks users to access several IP multimedia services from different terminals and IP access networks. Additionally, they intend to allow the operators to have a easier way for new services development, management and networks interoperability.

This paper purpose is to have a brief description of the IMS networks main features, that justify its selection as the NGN (Next Generation Network) networks control standard.

Keywords

IMS, IP, CSCF, AS, NGN, SIP, services, control e connectivity.

Abstract

The purpose of this article was to conduct a survey and analyze the factors that determine and determine the performance of software projects in our industry (including development, installation, migration among other types of projects).
This article is made up of a survey made to the Portuguese market, since the same benchmarking questionnaire was produced and analyzed in the American market.
This was translated and applied to our market, this questionnaire was prepared by the American consultant, PA Consulting and was sent to about 50 companies, of which 23 responses were obtained. This questionnaire allowed to obtain a knowledge of several factors, from the companies that responded, such as the branch of activity, the percentage of sales in several segments, whether they are project managers with a lot of or little experience, which type of projects generate , the duration and the planned budget, for the projects that manage, whether or not they make corrections, and also among others allowed to obtain a knowledge of the impact in the design phase and in the construction phase of several factors. The data were processed and statistical results, presented in the form of a graph, were obtained from the answers that the project managers provided in the questionnaire. The goal was also for this questionnaire to be sent to the top100 companies in our market and this is what happened.

Abstract

Nowadays, people have access to a variety of devices and applications to mediate their social interactions in any time and place. As a result, large amounts of information are generated which are not only heterogeneous but also dispersed, making it difficult to manage and analyze. Information Visualization presents a high potential to decrease cognitive load associated with data interpretation and to agglomerate information in a homogeneous way. Hence, it may potentially provide a comprehensive overview of such information, allowing users to understand their own patterns of social interaction in this personally relevant social context. This article introduces Trend Visualization (TreVi), which uses a variety of Information Visualization techniques to provide users with a unified view of their socially-generated personal information. It allows users to progressively explore the data in coherent and easily understandable items, allowing to maintain the context, while revealing personally relevant patterns.

Keywords

Information Visualization, Social Personal Information, User Interaction.

Abstract

The purpose of the current article is to analyze the peculiarity of 3D asset visualization in virtual reality devices, as well as research the more adequate techniques in 3D production for this type of medium. Having into account that the demand of content for these systems could grow significantly in a near future, development pipelines more optimized for virtual reality could become gradually more relevant, particularly in the relation between graphic quality and performance. As regularly these contents are integrated in real-time engines, it might be important to establish a comparative approach about the production processes within the videogame industry. In the end of this study, we will try to set those comparative elements, present some conclusions about suitable workflows and help to define good practices through the development process.

Abstract

The objective of the present work is to apply a dynamic mathematical model, of stochastic nature, in the simulation of the adhesion rate to the national public irrigation system. This model, by incorporating an adjustment process with error correction mechanism, allows the identification and simulation of the adhesion rate over time, from the short to the long term, through the mathematical lag operator. The adjustment of the model was made using the method initially developed by the German mathematician Gauss (1775-1855).

Abstract

The deployment of radio access networks that provide coverage to mobile phones has followed the progress of the available technologies, with the GSM, UMTS and LTE systems being available in combination, and 5G being in preparation. The exponential increase in traffic generated by mobile phone users requires dense deployments of high-cost radio stations. On the other hand, traffic suffers strong geographic and temporal variations, which require dynamic networks. New challenges arise for future networks, solutions that are scalable, dynamic and efficient. The networks of the future will be efficient and heterogeneous, sharing their resources among various operators. Its components will be software-based, using virtualization and the cloud paradigm to use resources in a flexible way. This will enable minimization of costs, and faster deployment and upgrade of networks. Only then will it be possible to respond to an increasingly intense and demanding use.

DOI: 10.31112/kriativ-tech-2018-01-10

Abstract

The empirical study, based on a qualitative research methodology, centered on multiple consulting / training case studies, was carried out under the Post-Doctoral project in Educational Sciences, at the Faculty of Education and Psychology, Universidade Católica Portuguesa, entitled "Collaborate to Innovate in Vocational Education", and intends to respond to the guiding question from the beginning: What training strategies can promote the change of teacher practices in the classroom and guarantee the quality of vocational education training? This qualitative research followed the Appreciative Inquiry (AI) - an approach to positive change that has been used successfully in communities and organizations around the world, noted in the literature by several authors [1][2][3]- based on the Cycle AI-5 D, consisting of five development phases: Define, Discovery, Dream, Design, Delivery (Destiny).Theories of research-actioncollaborative and reflexive education of [4], [5] [6] supported the workshop model of intervention and external consulting. The results show that the formative strategies have caused very significant impacts in terms of innovation and transformative effects, in the ways of thinking and acting professionals of the directors, teachers and trainers of schools with VET.

Abstract

Behavioural modelling is a new branch of Artificial Intelligence as well as Modelling and Simulation, lacking knowledge about the human decision-making process, which is not always obvious or rational, but dependent of emotions. When addressing the specific field of emergency situations and preparedness, for instance, when facing a fire, there is high degree of uncertainty regarding the actions that people do. To make it possible to elicit such knowledge it is proposed the use of Serious Games as a behavioural elicitation tool, to validate existing knowledge or elicit new behavioural information. This paper depicts the experiments made at LIACC. Using hypothetical scenarios, the user faces emergency situations impelling to take some action. Those scenarios were conceived and validated by experts, using the Delphi method and afterwards implemented using Unity3D. The experiments devised were tested using different user groups: adults in general, children and senior citizens. Results might be used by experts to test new hypothesis or confirm existing ones, and to feed pedestrian simulators.

Abstract

The aim of this research is to identify and build theoretical criteria in the determination of sustainability factors and evaluation models in this area of social solidarity institutions. A mixed method was used, based on two questionnaires: one for 138 social solidarity institution users and the other for 97 members of those institutions. To obtain qualitative data in the different areas under analysis, institution managers and local public authorities were also interviewed. The research produced knowledge that makes it possible to define seven new theoretical sustainability criteria: 1) support needs; 2) access to services; 3) suitability and quality of services; 4) culturality; 5) user satisfaction; 6) empowerment of institutions; and 7) relevance of the institutions. It also broadens two criteria already included in the literature: 1) interaction with society [and the state]; and 2) organisational structure [and functioning].
