Body area network for wireless patient monitoring
A BAN system is presented, which allows the connectivity of a wide range of heterogeneous body sensors to a portable hub device that is connectable to external networks (IEEE 802.11, GPRS) and can substantially improve the performance of different services, especially those that are health related.
Comparative study of automatic speech recognition techniques
A comparative study on different approaches that were proposed for the task of ASR, and which are widely used nowadays are presented.
Hardware-based support vector machine for phoneme classification
This paper presents the design of a digital hardware implementation based on Support Vector Machines (SVMs), for the task of multi-speaker phoneme recognition, and a priority scheme was also included in the architecture, in order to forecast the three most likely phonemes.

A complete analysis of the spur characteristics of edge-combining delay-locked loop (DLL)-based frequency multipliers is presented and a way to reduce the mismatch between the delay cells in the delay line is discussed via an analytic model and verified by the implementation of a delay cell in a 65-nm CMOS process.
Comparative study of gigahertz CMOS LC quadrature voltage-controlled oscillators with relevance to phase noise
This review paper presents a comparative study of published integrated submicron CMOS quadrature voltage-controlled oscillator designs, based on LC resonator tanks operating at gigahertz frequencies.…
Theoretical and finite element analysis of dynamic deformation in resonating micromirrors
Dynamic deformation is one of the limiting factors in the design of high frequency resonating microscanners that are intended for high definition raster scanning display applications. Out-of-plane…
Design optimization of a dynamically flat resonating micro-mirror for pico-projection applications
One of the main design limitations of resonant micro-mirrors, intended for visual projection display applications, is inertia-driven dynamic deformation. In order to achieve high scan angles,…
Mathematical formulation to predict the harmonics of the superconducting Large Hadron Collider magnets. II. Dynamic field changes and scaling laws
CERN is currently assembling the LHC (Large Hadron Collider) that will accelerate and bring in collision 7 TeV protons for high energy physics. Such a superconducting magnet-based accelerator can be…
