A low-complexity ECG feature extraction algorithm for mobile healthcare applications
No full textThis paper introduces a low-complexity algorithm for the extraction of the fiducial points from the Electrocardiogram (ECG). The application area we consider is that of remote cardiovascular monitoring, where continuous sensing and processing takes place in low-power, computationally constrained devices, thus the power consumption and complexity of the processing algorithms should remain at a minimum level. Under this context, we choose to employ the Discrete Wavelet Transform (DWT) with the Haar function being the mother wavelet, as our principal analysis method. From the modulus-maxima analysis on the DWT coefficients, an approximation of the ECG fiducial points is extracted. These initial findings are complimented with a refinement stage, based on the time-domain morphological properties of the ECG, which alleviates the decreased temporal resolution of the DWT. The resulting algorithm is a hybrid scheme of time and frequency domain signal processing. Feature extraction results from 27 ECG signals from QTDB, were tested against manual annotations and used to compare our approach against the state-of-the art ECG delineators. In addition, 450 signals from the 15-lead PTBDB are used to evaluate the obtained performance against the CSE tolerance limits. Our findings indicate that all but one CSE limits are satisfied. This level of performance combined with a complexity analysis, where the upper bound of the proposed algorithm, in terms of arithmetic operations, is calculated as 2:423N + 214 additions and 1:093N + 12 multiplications for N 861 or 2:553N + 102 additions and 1:093N +10 multiplications for N > 861 (N being the number of input samples), reveals that the proposed method achieves an ideal trade-off between computational complexity and performance, a key requirement in remote CVD monitoring systems

Manufacturing student leaders and cultivating six ingredients for success of an EMBS student organization
No full textWe present in this paper seven individual qualities of student leadership and emphasize six ingredients for successfully maintaining EMBS student clubs and chapters. Particularly, we provide a comprehensive view on segmented functions of an EMBS student organization, and discuss in detail the executive operations such as strategy management, program management with minimum-cost scheduling, recruitment and member development, seeking opportunities and supports from internal and external collaborations, building up information platform for communicating and construct institutional rules for indemnification of a health development. Our insights could help generate a general framework for sustainable development of an EMBS student organizatio

Equilibrium Structure, Hydrogen Bonding, and Proton Conductivity in Half-Neutralized Diamine Ionic Liquids
No full textRecent
experiments on proton conducting ionic liquids point to
half-neutralized diamine-triflate salts as promising candidates for
applications in power generation and energy conversion electrochemical
devices. Structural and dynamical properties of the simplest among
these compounds are investigated by a combination of density functional
theory (DFT) and molecular dynamics (MD) simulations based on an empirical
force field. Three different cations have been considered, consisting
of a pair of amine-ammonium terminations joined by a short aliphatic
segment −(CH2)n–
with n = 2, 3, and 4. First, the ground state structure,
vibrational eigenstates, and hydrogen-bonding properties of single
ions, neutral ion pairs, small neutral aggregates of up to eight ions,
and molecularly thin hydrogen bonded wires have been investigated
by DFT computations. Second, structural and dynamical properties of
homogeneous liquid and amorphous phases are investigated by MD simulations
over the temperature range of 200 ≤ T ≤
440 K. Structure factors, radial distribution functions, diffusion
coefficient, and electrical conductivity are computed and discussed,
highlighting the inherent structural heterogeneity of these compounds.
The core investigation, however, is the characterization of connected
paths consisting of cation chains that could support proton transport
via a Grotthuss-type mechanism. Since simulations are carried out
using a force field of fixed bonding topology, this analysis is based
on the equilibrium structure only, using geometrical criteria to identify
potential paths for proton conduction. Paths of connected cations
can reach a length of 80 cations and 30 Å, provided that bridging
oxygen atoms from triflate anions are taken into account. The effects
of water contamination at 1% weight concentration on the structure,
dynamics, and paths for proton transport are discussed
