Electrocardiograph (ECG) human identification has the potential to improve biometric security. However, improvements in ECG identification and feature extraction are required. Previous work has focused on single lead ECG signals. Our work proposes a new algorithm for human identification by mapping two-lead ECG signals onto a two-dimensional matrix then employing a sparse matrix method to proce...

KENDALL ATKINSON∗ AND OLAF HANSEN† Abstract. Consider being given a mapping φ : Sd−1 1−1 −→ onto ∂Ω, with ∂Ω the (d− 1)-dimensional smooth boundary surface for a bounded open simply-connected region Ω in Rd, d ≥ 2. We consider the problem of constructing an extension Φ : Bd 1−1 −→ onto Ω with Bd the open unit ball in Rd. The mapping is also required to be continuously differentiable with a non-...

Subspace mapping methods aim at projecting high-dimensional data into a subspace where a specific objective function is optimized. Such dimension reduction allows the removal of collinear and irrelevant variables for creating informative visualizations and task-related data spaces. These specific and generally de-noised subspaces spaces enable machine learning methods to work more efficiently. ...

Recently, a non-Hermitian chiral random matrix model was proposed to describe the eigenvalues of the QCD Dirac operator at nonzero chemical potential. This matrix model can be constructed from QCD by mapping it to an equivalent matrix model which has the same symmetries as QCD with chemical potential. Its microscopic spectral correlations are conjectured to be identical to those of the QCD Dira...

in the present paper, we introduce the sequence space [{l_p}(e,delta) = left{ x = (x_n)_{n = 1}^infty : sum_{n = 1}^infty left|  sum_{j in {e_n}} x_j - sum_{j in e_{n + 1}} x_jright| ^p < infty right},] where $e=(e_n)$ is a partition of finite subsets of the positive integers and $pge 1$. we investigate its topological properties and inclusion relations. moreover, we consider the problem of fin...

As the application of AMOLED becomes more and popular, technologies are needed to implement color management gamut mapping. The paper proposes a mapping method adjust temperature. We add additional white achieve control temperature when implementing tuning flow. original is also separated into RGW/RWB/WGB perform multiply 3x3 matrix iterate its XYZ calculation respectively. In experiment result...

Dynamic mapping of an object's local temperature distribution may offer valuable information for failure analysis, system control and improvement. In this letter we present a computerized measurement system which is equipped with a hybrid, low-noise mechanical-electrical multiplexer for real-time two-dimensional (2D) mapping of surface temperatures. We demonstrate the performance of the system ...
