General Assisted Living System Architecture Model
No full textNovel information and communication technologies create possibilities to change the future of health care and support. Ambient Assisted Living (AAL) is seen as a promising alternative to the current care models so a number of researchers have developed AAL systems with promising results. The main goal of AAL solutions is to apply ambient intelligence technologies to enable people with specific needs to continue to live in their preferred environments. In this paper, we are presenting a general architecture of system for assisted living that supports most of the use cases for such system
60 GHz UWB rake receivers in a realistic scenario for wireless home entertainment
No full textBy providing reliable high-capacity wireless links, the 60 GHz mmWaves band is expected to revolutionize the future wireless multimedia and home entertainment usage model, which is an inseparable part of the 5G concept. Besides the efforts within the frameworks of established standards, such as 802.15.3.c and 802.11ad, there is still lack of experimental measurements and performance evaluations in those environments that closely correspond to the different envisaged realistic application scenarios. Also, the potential of different transmission technologies at this band, besides the OFDM and SC-FDE, which are defined by the above mentioned standards, is not largely investigated in the literature. In this paper, based on UWB experimental channel impulse responses recorded in a modern residential environment, we evaluate the performance of Rake receivers to achieve high data rates (HDRs) with reasonable SNR, but still low Rake's complexity, with the purpose of meeting the QoS requirements of the wireless home entertainment use case. The bit-error rate performance evaluation of both partial and selective Rakes is applied to QPSK, 16-QAM and 64-QAM modulation schemes, defined in the existing standards. The promising results obtained in this study place the Rake receiver architecture as a valuable candidate for future 60 GHz WPANs and WLANs transceivers
Connected Health Development in R. Macedonia: Focus on Health Insurance Funds
No full textThe increasing adoption of Information and communication technologies (ICT) is widely recognized as a key factor for making healthcare more cost-effective. On the other hand, Connected Health involves the use of ICT to improve the quality service of healthcare and its outcomes. With the introduction of healthcare reform, many citizens of Republic of Macedonia are receiving access to a healthcare system that provides high-quality care at reduced costs, allowing the patients to save time and expense. The aim of this paper is to give a brief overview of the affection of e-services and electronic data exchange (between Fund's ICT systems and other IT systems in related healthcare institutions) at the healthcare quality for insured people, to facilitate the accessing and sharing of information and savings funds. Presented analysis can serve as a valuable input for the healthcare authorities in making decisions related to development of e-services in healthcare and connected health
Potentials of low-complexity Rake receivers for 60 GHz UWB wireless communication systems
No full textBeside the existence of well established standards targeting the 60 GHz mmWaves band and the availability of the very first commercial products on the wireless market, there are still open research challenges at different levels of system design. Considered as the future core short-range wireless technology, 60 GHz networks are expected to revolutionize the next-generation WPAN and WLAN experience by providing reliable and energy efficient multigigabit links at lower system design complexity. In this paper, based on our empirical measurements in different measurement scenarios, carefully created to closely correspond to real usage models, we show that low-complexity UWB Rakes have the potential to be considered as serious competitor to OFDM and SC-FDE for the future 60 GHz transceiver technology. Performance evaluation is realized by semi-analytical bit error rate analyses of different Rake architectures considering high data rate modulations. We show that low-complexity Rake receiver schemes are capable to provide sufficient performance using both standard-defined 64-QAM and ultra-wideband impulse radio signaling with 64-PPM and 64-PAM. The study is realized through the spectrum from 54 to 66 GHz and the effect of the carrier frequency on the performance is also discussed
Modulation and detection strategies for 60 GHz UWB high-data rate wireless indoor communications
No full text60 GHz mmWaves radios nowadays are considered as a core short-range wireless technology capable to solve the spectrum shortage due to the exponentially increasing number of wireless users and QoS sensitive multimedia and home entertainment applications. Although there are several published standards, the 60 GHz wireless developmental field is still open as the behavior of the channel is not well studied along the whole available bandwidth - at different carrier frequencies, and also, there is scarcity of research evaluating different transmission technologies besides the standard-defined OFDM and SC-FDE. In this paper, by carefully realized realistic application scenarios, we comparatively analyze the performance of different modulation and detection schemes, using experimental channel impulse responses recorded through an indoor measurement campaign in eight sub-bands from 54 to 66 GHz at several distances in two typical environments: office and residential. The measurements allow us to evaluate the impact of changes in multipath profiles, due to both frequency and surrounding environment, on the bit error rate performance of 60 GHz impulse radio (IR)-UWB signaling, i.e. pulse position modulation (PPM) and pulse amplitude modulation (PAM), and conventional quadrature amplitude modulation (QAM), comparing the performance of different schemes of Rake detection (partial and selective) in modern residential and office environments. The impact of the carrier frequency and the surrounding environment on the achievable performance is also discussed. The results obtained in this study show that different low-complexity Rake receiver architectures are valuable candidates for the future 60 GHz WPANs and WLANs transceivers
Development of the University’s Library Information System Model as an asset of the e-Society
No full textInformation society (e-Society) as new society base\ud
on networks, computer and communication capabilities,\ud
transforms the way that information is viewed and\ud
managed, and change the way the organizations manage\ud
their business processes. In this society the need for data\ud
integration in one place has been present more than ever.\ud
The key of success lies in creating appropriate information\ud
system based on new technology and network capabilities\ud
that will support the processes of the organization. The\ud
universities represent specific organizations with the highest\ud
priority of accessing to scientific knowledge. As academic\ud
institutions which produce knowledge, universities use and\ud
manage information from both: internal and external\ud
sources. e-Society offer a new dimension for communication\ud
between the students, professors and administrative staff by\ud
allowing quick access to information from an unlimited\ud
number of users from different locations at any time, with\ud
the possibility of further processing and use thereof. The\ud
existence of library information system (LIS) is a predisposition for quality assurance in universities. The\ud
purpose of this paper is to propose a model for University’s\ud
Library Information System (ULIS) that integrates\ud
information in a simple way, and allows quick access to\ud
books, electronic materials (internal books, lectures,\ud
manuals, presentations etc.), articles or research results\ud
from each member (unit) of the university
LOCAL GOVERNMENT CAPACITIES AND CIVIL ORGANIZATIONS IN MACEDONIA: CURRENT STATES AND IMPLICATIONS
Full text linkThe purpose of the paper is to analyze the capacities of the local governments in Macedonia when dealing with NGOs in the country. The main research methods that are applied in the paper are literature review, national survey results and modeling of IT support in the process of cooperation between municipalities and NGOs. The local governments still do not have well organized unit dedicated to civil organizations. Most have adopted an official document and apply all the legal forms of cooperation, but not all of them financially support civil organizations. In practice, local governments must strengthen the cooperation with civil organizations, especially by improving the application of IT technology. The social implications strongly depend on further strengthening the collaboration by applying IT knowledge during the process of civil dialogue
