Intelligent Transportation Systems (ITS) aim to improve safety, mobility and environmental performance of road transport. The INSIGMA project provides a fresh look at the possible innovations in this field, by enhancing the functionality and accuracy of ITS in urban environments. This paper describes the architecture, sensors, processing algorithms, output modules and advantages of the developed system. A comparison of existing ITS systems has been provided as background. Special attention has been given
The acceptance of e-health solutions by users representing the main professional groups in the healthcare system is of key importance for the successful development of this field. The attitude of nurses to information technology may influence the process of shaping an e-health environment. This survey was conducted to assess the use of information technologies and opinions about e-health among nurses employed in hospital centers located in an urban area in Poland. The questionnaire included items on the use of computers and the Internet, perception of the importance of e-health systems, and opinions about the roles and benefits of e-health for healthcare stakeholders. The questionnaire was distributed to 215 nurses participating in extension courses. The analysis was performed on 153 questionnaires accepted after quality control. The respondents were convinced about the importance of information technology in the delivery of healthcare services and specifically of e-health systems; however, there was a significant group that expressed skepticism about the need for the development of e-health services in Poland at the moment. The respondents indicated the Ministry of Health, the National Health Fund, and public health specialists as the stakeholders who should have the most important role in initiating e-health development.
Abstract. This paper describes an attempt to analyze frequencies of noise occurring in urban areas using an Android-based smartphone. The proposed solution enables audio writing to the device's memory, analysis on the device and transmission of results to the server. The article presents results of tests carried out in the city of Krakow.
Multicarrier or multitone modulations (MTM) are efficient techniques for transmission of digital data over a copper wire. Most significant propetty of MTM is low sensitivity to the narrowband noise. All MTM are accomplished digitally. Due to high complexity, MTM transceivers were implemented at last decade, when suitable processors were manufactured. At present MTM have wide applications in Digital Subscriber Lines (DSL). ANSI T1.413, Asymmetric DSL (ADSL) standard and ITU G.992, defines Discrete Multitone modulation (DMT), known as well as Orthogonal Frequency Division Multiplexing (OFDM).In this paper we introduce a simple MTM modulation, which we call Discrete Cosine Multitone (DCMT). DCMT possesses two important properties: it is more efiicient than DMT, and provides lower complexity of a transceiver.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
