Analysis of Extended Busy Tone Performance for Coexistence between WRAN and WLAN TVWS Networks
(IEEE, 2015)
TV White Spaces indicate spectrum bands which were reserved for licensed terrestrial TV broadcasting and opened to unlicensed use under regulatory conditions. One important regulation which is common in all regulatory ...
Low Energy Fixed Clustering Algorithm (LEFCA) for Wireless Sensor Networks
(IEEE, 2015)
Wireless sensor networks (WSNs) have become an important part of our lives as they can be used in vast application areas from disaster relief to health care. As a consequence the life span and the energy consumption of a ...
Pilot Symbol Assisted Channel Estimation for 4x4 Space Time Block Coded Spatial Modulation Systems
(IEEE, 2015)
Recently spatial modulation (SM) and space-time block coding (STBC) are combined to take advantage of the benefits of both while avoiding their drawbacks for multiple-input and multiple-output (MIMO) systems. The pioneering ...
Panel Data Analysis of Foreign Direct Investment and Poverty from the Perspective of Developing Countries
(Elsevier Science, 2014)
The purpose of this paper is to assess the relationship between foreign direct investment (FDI) and poverty at the macro-pathway in selected developing countries. The contribution to host countries from FDI can take several ...
Tablets as primary educational computing devices. An impact analysis on the educational landscape in an Austrian university.
(Elsevier Science, 2014)
In this study we analyze how tablet devices could be used as educational tools to support innovative educational practice in a university in Austria. Students and educators were issued tablet devices in 2011 across the ...
Modeling and Equalization of Indoor Visible Light Channnels
(IEEE, 2016)
In this paper a computationally efficient method is proposed for modeling the indoor visible light communications (VLC) channels using a non-sequential ray tracing technique. We created three dimensional realistic simulation ...
Level Densities of Heavy Nuclei in the Shell Model Monte Carlo Approach
(EDP Sciences, 2016)
Nuclear level densities are necessary input to the Hauser-Feshbach theory of compound nuclear reactions. However the microscopic calculation of level densities in the presence of correlations is a challenging many-body ...
Smart Systems From Design to Implementation of Embedded Smart Systems
(IEEE, 2016)
This paper aims to explain the design and implementation procedure of embedded Smart Systems. The idea is supported by four different Smart Systems as Smart Home Smart Agriculture Smart Campus and Seat and Study Module of ...
Comparison of Compressed Sensing Based Algorithms for Sparse Signal Reconstruction
(IEEE, 2016)
Compressed sensing theory shows that any signal which is defined as sparse in a given domain can be reconstructed using fewer linear projections instead of using all Nyquist-rate samples. In this paper we investigate basis ...
Persistence of Vibrational Collectivity in Nuclear Level Densities
(E D P SCIENCES, 2016)
By applying the particle-number projection to the finite-temperature BCS theory to the state densities in the rare-earth nuclei and comparing its results to the SMMC ones we investigate effects of the particle-number ...
