Predicting lorawan behavior. How machine learning can help
2020
Large scale deployments of Internet of Things (IoT) networks are becoming reality. From a technology perspective, a lot of information related to device parameters, channel states, network and application data are stored in databases and can be used for an extensive analysis to improve the functionality of IoT systems in terms of network performance and user services. LoRaWAN (Long Range Wide Area Network) is one of the emerging IoT technologies, with a simple protocol based on LoRa modulation. In this work, we discuss how machine learning approaches can be used to improve network performance (and if and how they can help). To this aim, we describe a methodology to process LoRaWAN packets a…
Virtual Vehicles Manager: a java virtual reality environment for distributed multi vehicles dynamics control and simulation
2007
This paper describes a lightweight, full portable software environment for development, simulation and control of vehicles. All the software is developed in Java so there are many advantages as portability, multithreading distribution etc. This environment simulates the vehicles integrating their non-linear differential equation systems. The equation systems can easily be modified changing that representation class so it is easy to manage different vehicles. The scenario is displayed as a 3D virtual reality environment in which all the objects are rendered using a combination of 3 d primitive. It is also possible the use of pre-built 3 d objects loaded from files in 3 ds format. The softwar…
Printed Antennas for Sensor Applications: A Review
2014
With the expansion in number and requirements of modern wireless communications, the technology related to their associated antennas has been continuously improved. Among other options, printed antennas offer excellent features, such as low weight, profile, and cost, while maintaining good performance characteristics. In addition, their straightforward integration with electronics has opened new fields of application such as smart sensing systems. Printed antennas can be used in different parts of a wireless smart sensor as a radio link, sensing element, or even as energy harvester. In this paper, we present a thorough review of recent advances of printed antennas as regards their use in sm…
Analysis of research on web usability for people with cognitive disability from 2002 to 2011
2012
We present a review of research over the last decade on web usability for people with cognitive disabilities. Our aim is to know current status on the issue of usability in relation to people with cognitive disabilities to consider the issues they present and future solutions. We proceeded to perform a review in specialized databases of different scientific disciplines. We describe the results and we discuss empirical studies which evaluated usability of websites for people with cognitive disabilities. Conclusions and future lines are presented.
Challenges in the Redesign of Content Management
2005
The Finnish Centre for Pensions (FCP) is a government organization acting as the central body for private pension institutions in Finland. One of its central tasks is to produce and publish guideline documents for ensuring that the pension institutions carry out pension provisioning in a unified way. Due to problems in the maintenance of the documents and requests for faster information delivery by the Internet, FCP carried out a content management development initiative during 2002-2004. The case follows the changes in components of the content management environment: in the activities of work processes, actor roles, systems, and content items. The case shows that in content management red…
Challenge of tacit knowledge in acquiring information in cognitive mimetics
2019
Intelligent technologies are rising. This is why methods for designing them are important. One approach is to study how people process information in carrying out intelligence demanding tasks and use this information in designing new technology solutions. This approach can be called cognitive mimetics. A problem in mimetics is to explicate tacit or subconscious knowledge. Here, we study a combination of thinking aloud in ship simulator driving and focus group commenting the solutions of subjects. On the ground of these early experiments, a multiple method combination seems to be the best way forward to solve problems of tacit or subconscious knowledge. peerReviewed
HL7v3 CDA Rel.2 prescription: Localization experience and GP Integration Project
2010
The localization experience for the e-prescription, based on the Health Level Seven Version 3 (HL7v3) Clinical Document Architecture, Release 2 (CDA Rel.2), is presented. As application, we propose a project of General Practitioners Integration with the EHR (Electronic Health Record), implementing the e-prescription, patient summary and other CDA Rel.2 documents. The integration is made possible with HL7v3, the most widely used standard for healthcare information interoperability. The project is in line with the state of the art in the normative referring context for the Italian Healthcare, both at national and regional level (Tuscany Region). Final remarks are drawn, also referring to the …
Behavior Pattern Simulation of Freelance Marketplace
2012
Labour market is expanding rapidly nowadays. Therefore, recruitment processes, namely, the processes of job searching and job offer have become more complicated and there is a strong tendency to automate and integrate it in special freelance marketplaces, i.e. web solutions which seek for the best match for a buyer and seller analyzing the services and items they offer. The aim of the current research is to find possible improvements to the existing system via the implementation of the Multi-Agent-System paradigm. We model the whole marketplace as a continuous process with different agents (freelancers) and propose several behavior models of agents. We analyze different strategies with the …
XML Enabled Metamodeling and Tools for Cooperative Information Systems
2001
The development of tools to support semantic resolution is a key issue in the design of heterogeneous interoperable information systems. This paper presents a methodology and a data model translator toolkit, called X-TIME, for the design and management of interoperable information systems. X-TIME combines a metamodelling approach and XML features to provide support for automated design of wrappers or semantic reconciliators. It is a flexible semantics oriented approach that takes into account several important characteristics of interoperable information systems, including extensibility and composability. Extensibility requires a translation scheme that can easily integrate new data models.…
