Showrooms as a Window to Science Based Innovation

Abstract

Scientific results benefit from more tangible stakeholder communication. Showrooms are a tool to transform abstract scientific concepts into solution-oriented and less complex demonstrators. The basic idea of a showroom implies a smart expo and meeting place to demonstrate the latest technological developments in a comprehensive and interactive manner and to stimulate transfer of scientific results to practice. Presentation of new technologies can be an eye opener of what can already be done today. But it is just more than this as it can put discussion with interested stakeholders to a new level - allowing to think beyond this - paving the ground for innovation. This way a showroom stimulates very substantial discussion about future ideas with real involvement of industry and society. Involving the public via a showroom environment is also helpful for the diffusion of new ideas, leading to potential faster market take-up, when new solutions are put into reality. Furthermore the interaction with the public is a stimulus also for the scientist, raising a much better understanding about current and future needs.

Capability is understood as a measure of the ability of an entity (organization, person, system) to achieve its objectives in relation to its overall mission professional science communication is part of the capability of, e.g., a university. Innovation capability in this sense refers to the ability of a set of regional stakeholders from academia, political authorities, public administrations and industry to innovate in synergy for economic and societal development – showrooms are an important tool to achieve this.

Analysis of RDF Syntaxes for Semantic Web Development

Abstract

In this paper authors perform a research on possibilities of RDF (Resource Description Framework) syntaxes usage for information representation in Semantic Web. It is described why pure XML cannot be effectively used for this purpose, and how RDF framework solves this problem. Information is being represented in a form of a directed graph. RDF is only an abstract formal model for information representation and side tools are required in order to write down that information. Such tools are RDF syntaxes – concrete text or binary formats, which prescribe rules for RDF data serialization. Text-based RDF syntaxes can be developed on the existing format basis (XML, JSON) or can be an RDF-specific – designed from scratch to serve the only purpose – to serialize RDF graphs. Authors briefly describe some of the RDF syntaxes (both XML and non-XML) and compare them in order to identify strengths and weaknesses of each version. Serialization and deserialization speed tests using Jena library are made. The results from both analytical and experimental parts of this research are used to develop the recommendations for RDF syntaxes usage and to design a RDF/XML syntax subset, which is intended to simplify the development and raise compatibility of information serialized with this RDF syntax.

The Model Transformation for Getting a UML Class Diagram from a Topological Functioning Model

Abstract

The approach called Topological Functioning Modeling for Model Driven Architecture (TFM4MDA) uses a Topological Functioning Model (TFM) as a formal Computation Independent Model (CIM) within the Model Driven Architecture (MDA). The object of this research is the construction of a UML class diagram on the Platform Independent Model (PIM) level in conformity with the TFM. Nowadays this transformation is executed manually. Manual creation of models is time-consuming and there is a risk of making mistakes. These drawbacks increase expenses and reduce efficiency of TFM4MDA approach. That is why automation of transformation is useful. The paper presents an algorithm for the transformation which is written in a pseudocode and can be implemented as a tool.

Towards E-Learning Capability Maturity Model

Towards E-Learning Capability Maturity Model

In the software development Capability Maturity Model (CMM) is a methodology for constantly optimizing organization's software development processes in order to meet project deadlines and customers' satisfaction in more efficient way. Nowadays e-learning becomes a valuable business tool not only for reducing costs and improving employees' competences in specific business areas but also for creating considerable Return on Investment (ROI) for the businesses. More and more companies choose an e-learning environment over classic classroom learning. When more companies are implementing e-learning it is time to create a common workplace e-learning CMM which defines the framework and best practices for e-learning business processes that can be used as standard and guidelines for companies which are starting e-learning projects as well as companies practicing e-learning. The paper proposes e-learning implementation and maintenance business processes incorporated in the classic PDCA cycle consisting of four e-learning project phases - e-learning project planning, e-learning system implementation, e-learning monitoring and e-learning optimization.

ICT Supporting Daily Physical Activity - with Special Reference to Pedometers in the Step-Shape Project

ICT Supporting Daily Physical Activity - with Special Reference to Pedometers in the Step-Shape Project

Physical inactivity (PA) is one of the leading risks for mortality worldwide. One of future main drivers for physical activity could be information and communication technology gadgets and services that support active way of living. This study focuses on investigating and understanding how individuals use pedometers to support their physical activity and what their end-user experience is. In addition to individual scope, this is also important both for information society and healthcare organizations. They urgently require new approaches and tools to reshape their customers' inactive lifestyle. Data for this study was collected with semi-structured questionnaire from subjects who used pedometers for a three month period and reported the daily step. The participants increased their PA during the project and most of them also informed on their intention to continue the more active lifestyle. The pedometer and the developed step collection table were easy to use and useful in supporting PA. ICT will inevitably play a major role in promotion of physically active lifestyle.

The generic map visualization framework

Abstract

- Controlling robots using a multi-agent system is becoming an active research area which includes a lot of challenges regarding localization, management, coordination, task allocation, etc. It is a very important for a human to overview such a system visually - to monitor a robot status, performance and other characteristics. At the same time some concepts relate to all such systems - robots act in certain environment, where there are different kinds of obstacles and objects. In order to fasten initiation of such visualization tools, a new framework is proposed - “Mapclipse” which is based on the popular Eclipse framework. The purpose of the framework is to create a common domain model, API for its management (like reflecting object movements, environment modifications, etc.), a basis for common visualization tasks and provide a means to customize the figures of specific types of objects. This paper describes the concept of the system in detail, the current prototype of framework, some of its extensions, as well as highlights the main challenges in the future.

Social Media-Related Cybercrimes and Techniques for Their Prevention

Abstract

Since a past decade, social media networking has become an essential part of everyone’s life affecting cultural, economic and social life of the people. According to internetlivestats.com, in March 2019 the Internet users reached 4 168 461 500, i.e., 50.08 % penetration of world population. According to Statista, in 2019 there are 2.22 billion social media networking users worldwide, i.e., 31 % of global social media networking penetration and it is expected that in 2021 this number will reach 3.02 billion. These social networking sites are attracting users from all walks of life and keeping these users’ data in the cloud. Today’s big challenge is related to an increase in volume, velocity, variety and veracity of data in social media networking, and this leads to creating several concerns, including privacy and security; on the other hand, it also proves as a tool to prevent and investigate cybercrime, if intelligently and smartly handled. The law enforcement agencies are putting their utmost efforts to prevent cybercrime by monitoring communications activities over the Internet. In this paper, the authors discuss recommendations and techniques for preventing cybercrime.

Testing and Traceability Aspects in the Context of the Model Driven Architecture (MDA)

Testing and Traceability Aspects in the Context of the Model Driven Architecture (MDA)

With the growth of complexity of the software systems it becomes more complicated to ensure and evaluate quality of the software being built. This paper discusses quality of the software in the context of the Model Driven Architecture. Paper analyses factors that affect quality of the software in the software development projects that are developed using MDA. As one of the important factor that affects quality of the software, is traceability. This paper provides description of the traceability property and importance of it within development of the software. Within context of this paper traceability is considered as a property of a system description technique that allows changes in one of the system descriptions to be traced to the corresponding portions of the other descriptions. This paper is focused on such aspects of the software development as testing and traceability in the context of MDA. Paper contains in review of traceability, MDA and traceability within MDA. Also paper contains description of the method for formal definition of the problem domain - called Topological functioning modeling for model driven architecture (TFMfMDA). This paper introduces method of the application of the TFM as the traceability tool. TFM as the traceability tool can be used to analyze impact of the changes and select most important tests.
