In this paper, we present techniques for ellipsoid fitting which are based on minimizing the sum of the squares of the geometric distances between the data and the ellipsoid. The literature often uses “orthogonal fitting” in place of “geometric fitting” o... see more

Finding the orthogonal (shortest) distance to an ellipsoid corresponds to theellipsoidal height in Geodesy. Despite that the commonly used Earth referencesystems, like WGS-84, are based on rotational ellipsoids, there have also been overthe course of the ... see more

Orthogonally splitting imaging pose sensor is a new sensor with two orthogonal line array charge coupled devices (CCDs). Owing to its special structure, there are distortion correction and imaging model problems during the calibration procedure. This pape... see more

Facial expression recognition (FER) under active near-infrared (NIR) illumination has the advantages of illumination invariance. In this paper, we propose a three-stream 3D convolutional neural network, named as NIRExpNet for NIR FER. The 3D structure of ... see more

This research based on simulation to show impact of the power allocation on Non-Orthogonal Multiple Access (NOMA) using Successive Interference Cancellation (SIC). NOMA used superposition code (SC) on the transmitter and SIC on the receiver. NOMA has two ... see more

In this paper we prove that there do not exist orthogonal instanton bundles on P^{2n+1} . In order to demonstrate this fact, we propose a new way of representing the invariant, introduced by L. Costa and G. Ottaviani, related to a rank 2n instanton bundle... see more

Let A be a unital B_{0}-algebra with an orthogonal basis, then every multiplicative linear functional on A is continuous. This gives an answer to a problem posed by Z. Sawon and Z. Wronski.

In this paper, we introduce a new class of symmetric orthogonal polynomials that generalizes the class of Dunkl-classical ones. As applications, we give some new characterizations of the symmetric semiclassical orthogonal polynomials.

The theory of set-valued mappings has grown with the development of modern variational analysis. It is a key in convex and non-smooth analysis, in game theory, in mathematical economics and in control theory. The concepts of nearness and orthogonality hav... see more
