Abstract: In this paper, we propose a new phased array calibration method that measures all antenna element ... According to the superposition principle of electromagnetic field, a set of linear ...

Abstract: This article considers a system coupling an ordinary differential equation with a wave equation through its boundary data. The existence of a small parameter in the wave equation (as a ...

To solve the model, a proxy-based optimization approach is proposed, where a semiparametric statistical method (i.e., clusterwise linear regression) is used to create a set of rapid-response and ...

In addition, special topics, including equity risk premia, simultaneous-equation approach for security valuation, and Itô's calculus, are also included for advanced students and researchers.

☕ Symja - computer algebra language & symbolic math library. A collection of popular algorithms implemented in pure Java.

This paper is based on our previous works in the past decade and is a summary of the theory of the amplitude-phase retrieval problem in any linear transform system and its applications. We describe ...
