In this paper, we discuss an iterative method for the model order reduction of continuous linear time-varying (LTV) periodic descriptor systems where the system's matrices are singular. The model order reduction strategy proposed here is focused on the linear time-invariant (LTI) reformulation of th...

Large, complex dynamical systems, such as, power systems, are very challenging task to model and analysis.Numerous techniques have been developed to handle the difficulties arising from the size and complexity of typical realistic power system models.These complexities demand to formulate reduced or...

Objective of this study is to analysis the MHD flow over a curved stretching surface. In this model we incorporated the radiation, mixed convection and partial slip parameter. Using a curvilinear coordinate system developed a mathematical model and the system of basic governing equations are convert...

In this paper, we present an efficient algorithm for model reduction of discrete-time index-2 descriptor systems arising in context of linear time invariant (LTI) control and stability of descriptor systems. We propose a Smith-based iterative method for the model order reduction (MOR) strategy which...

We have presented an efficient approach for reduce order modeling of discrete-time linear time-invariant (DT-LTI) index-2 descriptor systems which arise in the study of control system. This paper is a follow up and advancement of our previous work [1]. The contribution of this paper lies in finding ...

In this paper, we propose a projection based iterative technique for model order reduction (MOR) of time-varying periodic descriptor systems in continuous setting. This is a two sided projection technique which combines the SVD and the Krylov subspace method. We first apply a simple descretization s...

The impact of variable fluid properties (viscosity and thermal conductivity) and magnetic dipole on biomagnetic Maxwell fluid past a stretching sheet with slip velocity and heat generation/absorptionhave been studied. Similarity transformation technique is adopted to obtain the self-similar coupled ...

In this paper, we present a structure preserving Smith based iterative method for the model order reduction of index-2 periodic descriptor systems. The work of this paper is twofold. The first half of our work focuses on reformulating a discrete-time descriptor system into a discrete-time generalize...

Student engagement needs to be context-specific to embrace holistic learning for increasingly diverse students in higher education. This paper presented a case study on the context-specific adaptation of a student engagement measure for a private university in Bangladesh. The adaptation process invo...

Since the early 90s higher education institutions (HEIs) have been globally experiencing a shift from ‘traditional’ to ‘outcome-based education (OBE)’ approach, which allows learners to actively construct knowledge and enjoy learning with peers and teachers. However, the ...

Abstract This paper is a comparative analysis of two prominent iterative algorithms for model order reduction of linear time‐varying (LTV) periodic systems where the system's matrices are singular. Our proposed method is based on a reformulation of the LTV model to an equivalent linear time‐invarian...
