This paper presents H∞ control problem for input-delayed systems. A neutral system approach is considered to the design of PD controller for input delay systems in presence of uncertain time-invariant delay. Using this approach, the resulting closed-loop system turns into a specific time-delay system of neutral type. The significant specification of this neutral system is that its delayed coeff...

. In this paper, we address the dense-sparse matrix product (DSMP) problem i.e. where the first matrix is dense and the second is sparse. We first present initial versions of loop nest structured algorithms corresponding to the most used sparse matrix storing formats i.e. DNS, CSR, CSC and COO. Afterwards, we derive several versions obtained by applying loop interchange techniques, loop invaria...

This paper focuses on the non-fragile guaranteed cost control problem for a class of T-S fuzzy time-varying delay systems with local bilinear models. The objective is to design a non-fragile guaranteed cost state feedback controller via the parallel distributed compensation (PDC) approach such that the closed-loop system is delay-dependent asymptotically stable and the closed-loop performance i...

We use free boson techniques to investigate AD -E-quiver matrix models. Certain higher spin fields in the free boson formulation give rise to higher order loop equations valid at finite N. These fields form a special kind of W-algebra, called Casimir algebra. We compute explicitly the loop equations for A r and D r quiver models and check that at large N they are related to a deformation of the...

A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...

Optimizations: 1) Loop Optimization [1]: A typical matrix-vector multiplication (matrix in CSR format) consists of a nested loop where the outer loop iterates over all the rows and the inner loop iterates over columns in those rows. Since the data is stored in a sequential fashion in CSR (one row after the other), the data can be accessed by the nested loop using a single loop variable instead ...

In this article we present an emulation strategy for one-loop matrix elements. This is based on the factorisation properties of elements and extension work presented in arXiv:2107.06625. We show that a percent-level accuracy can be achieved even large multiplicity processes. The point obtained such it dwarfs statistical training sample which allows us to use our model augment size set by orders...
