Multimodal Wireless Sensor Network-Based Ambient Assisted Living in Real Homes with Multiple Residents Tunca, Can; Alemdar, Hande; Ertan, Halil; Incel, Ozlem Durmaz; Ersoy, Cem (MDPI AG, 2014-06-01) Human activity recognition and behavior monitoring in a home setting using wireless sensor networks (WSNs) provide a great potential for ambient assisted living (AAL) applications, ranging from health and wellbeing monitoring to resource consumption monitoring. However, due to the limitations of the sensor devices, challenges in wireless communication and the challenges in processing large amounts of sensor data in order to recognize complex human activities, WSN-based AAL systems are not effectively integr...
Spectroscopic measurements of electron temperature and electron density in electron beam plasma generator based on collisional radiative model Goktas, H.; Demir, A.; Kacar, E.; Hegazy, H.; Turan, Raşit; Oke, G.; Seyhan, A. (Informa UK Limited, 2007-01-01) The current work describes a spectroscopic method for determining the electron temperature and electron density in an electron beam generator using argon spectral lines based on a collisional radiative model. Neutral and first-ionized Ar lines emitted from the electron beam generator are studied experimentally. A collisional radiative code was developed to simulate the Ar (I) and Ar (II) spectral emission and to compare the results with the experimental data for electron density and temperature determinatio...
Optical Modulation With Silicon Microspheres Yüce, Emre; Serpenguzel, Ali (Institute of Electrical and Electronics Engineers (IEEE), 2009-10-15) In this letter, a silicon microsphere coupled to a silica optical fiber half coupler has been characterized for electrooptical modulation in the L-band at 1.55 mu m. Electrooptical modulation of the transmitted and the 90 degrees elastic scattered signals for both the TE and the TM polarizations of the microsphere resonances has been observed.
Raman Spectroscopy Investigation of Nano Hydroxyapatite Doped with Yttrium and Fluoride Ions Yilmaz, Bengi; Evis, Zafer (Informa UK Limited, 2014-01-02) In this study, nano hydroxyapatite doped with yttrium (2.5, 5, and 7.5mol%) and fluoride (2.5mol%) ions were synthesized by precipitation method and sintered at 900 degrees C, 1100 degrees C, and 1300 degrees C. Raman spectroscopy was applied to track the structural modifications in pure and doped hydroxyapatites. The results showed that the main characteristic band of pure hydroxyapatite at 963cm(-1) was not affected significantly by ion doping but exhibited higher intensity with increasing sintering tempe...
Electromagnetic Target Classification using time frequency analysis and neural networks Sayan, Gönül; Leblebicioğlu, Mehmet Kemal (Wiley, 1999-04-01) This paper demonstrates the feasibility and advantages of using a self-organizing map (SOM)-type neural network classifier for electromagnetic target recognition. The classifier is supported by a novel feature extraction unit in which the Wigner distribution (WD), a time-frequency representation, is utilized for the extraction of natural-resonance-related energy feature vectors from scattered fields. The proposed target classification technique is tested for a set of canonical targets, displaying an excelle...
