Programs

Currenty the department runs a 21 (twenty one) credits "Math Minor" program. A 23 (twenty three)  credits "Physics Minor" progarm is submitted for academic review. We hope to launch this very soon. However, a complete program of MSc in Applied and Computational Sciences (AMCS)  is under preparation. Our vision is to transform our department from present course offering position to a full-fledged department which among other things will offer a major in Mathematics as well as a major in Physics. 

  Math Minor Program  

•   21 credits Math Monir program.
•   Students need to complete the following 7 (seven courses) each of 3 (three) credits:  MAT-120 (Calculus and Analytic Geometry-I) , MAT-125(Introduction of Linear Algebra), MAT-130 (Calculus and Analytic Geometry-II) , MAT-250 (Calculus and Analytic Geometry-III) , MAT-370 (Real  Analysis) , MAT-480 (Differential Equations) and MAT-485 (Operation Research).
•   If a student completes any of the above courses as a part of his/her core degree program, S/he needs to do the rest of the courses to complete the Math Minor program.
•   Course outlines of the above courses can be found under the "Courses" manu of the departmental webpage.

Program

Department of Mathematics and Physics (DMP), North South University (NSU), celebrated the pi-moment of the century at the campus. Pi is the ratio of the circumference of a circle to its diameter. It is symbolized by the greek letter pi in the lower case (π). This is a fixed quantity, which is usually taken to be 3.14. The number of digits after the decimal is infinite. In the western countries, especially in the US, March 14 (written 3/14 in the American style) is celebrated every year as the pi-day. March 14 this year is a bit more special. The first ten digits of the value of pi, i.e., 3.141592653 can be arranged as March 14, 15, 9:26:53. We call this special moment as the pi-moment. This moment will come again in 2115, one hundred years later.

At this precise moment (according to Bangladesh-time) of this century, students from various departments of NSU participated in a celebration of the moment. They formed a human circle with a diameter. Then dividing the number of people in the circumference by the number of people in the diameter yielded a value close to the actual value of pi. They did the same thing with chairs. At the end a large number of people formed the shape of the symbol π.  

Professor Partha Pratim Dey, the chairman of the Department was present at the event along with a few other faculty members, namely, Kazi Abu Sayeed, Hasina Akter, and Muhammad Asad-uz-zaman. A few part time faculty members were present as well as Golam Dastegir Al Quaderi, a faculty member of the Physics Department at Dhaka University, who participated as a guest. The initiative was taken by Naureen Ahsan, a part time faculty member at NSU and a full time faculty member at Dhaka University.

Message from the Chair

The Department of Mathematics and Physics is one of the dynamic departments of North South University, which incorporates fundamental, experimental and mathematical study. We are committed to excellence in teaching and research. At present the department does not offer any major program, but it offers the mathematics and physics courses for all undergraduate students of different disciplines across the university.  The department runs a 21 credit Mathematics minor and a 15 credit Physics minor to attract the most talented Engineering, Economics, and Business and Environmental sciences majors.

The strength of the department is grounded not only in the transmission of ideas and knowledge through quality teaching, but also in the cutting-edge research and scholarly achievements of our faculty members. Fifteen of our twenty four full-time faculty members are Ph.D. s from North America, Australia or Western Europe. The breadth of expertise of our faculty members covers almost the entire range of mathematics and physics, pure as well as applied. They are active in developing new ideas and results exploring the latest knowledge of mathematics and physics with modern computation skills profound to solve problems in the engineering and computational sciences, physical and biological sciences, economics and business.

The Department of Mathematics and Physics is located on the 10^th floor of the SAC building of NSU. Currently we have  full-time and part-time faculty members in our department. The part-time faculty members are from among the best faculty members of the reputed universities in Dhaka like Dhaka University, Bangladesh University of Engineering and Technology etc.

We have a plan to transform our department from present service position to a full-fledged Department of Mathematical Sciences, which among other things will offer a major in mathematics as well as a major in Physics. I believe, given our faculty strength, this transformation should be a piece of cake.

Title: A Mathematical Model and Optimal Control Strategy for the Co-infection of COVID-19 with Kidney Disease.

Abstract: The COVID-19 pandemic poses significant health risks, especially when interacting with concurrent conditions like kidney disease, an aspect largely unexplored in current literature. This study introduces a deterministic mathematical model to investigate the dynamics of COVID-19 co-infection with kidney disease, aiming to provide insights for effective control strategies. The model, based on a Susceptible-Infected-Recovered framework with seven compartments, integrates disease-free and endemic equilibrium and explores the basic reproduction number for stability assessment. Sensitivity analysis reveals that COVID-19 increases co-infection risks with kidney disease, emphasizing the need for targeted interventions. Numerical simulations illustrate outcomes of treating COVID-19, kidney disease, and co-infection scenarios, advocating for integrated control measures. By utilizing Pontryagin's Maximum Principle, the study proposes and analyzes public health education, lifestyle promotion, and specialized treatment strategies. Parameter adjustments via Bayesian and least squares methods align model predictions with epidemiological data, validating effective control strategies identified in the literature. This integrated approach underscores the importance of comprehensive healthcare strategies in mitigating the complex interactions between COVID-19 and kidney disease, offering a framework to streamline global health responses.

Title: Design and Development of Printed Capacitive Acoustic Resonant Sensor

Abstract: Acoustic sensors work by converting sound waves into electrical signals. These sensors are designed to detect variations in air pressure caused by sound and transform those pressure fluctuations into electrical signals that can be further processed, stored, or transmitted. This work is focused on the design and development of a low-cost resonant capacitive acoustic sensor using printing techniques. The main objective of the work is to improve the geolocalization of the RFID tags for industrial application. The finite element modeling and design of experiments (DOE) was employed for the design adaptation and optimization of the sensor. Different technological building blocks were then developed, characterized and optimized. Finally, the prototypes of acoustic resonant sensors were fabricated combining 2D inkjet printing and polyjet 3D printing techniques, and the functionalities of the sensors were characterized using various techniques. Experimental results showed that sensitivity and selectivity were within the specifications and in good agreement with the modeling results.

Title: Reduced Realization and Model Reduction of Switched Linear Systems.

Abstract: In the last several decades, switched systems gained much interest as a modeling framework in many applications. Due to a large number of subsystems and their high-dimensional dynamics, such systems result in high complexity and challenges. This motivates to find suitable reduction methods that produce simplified models which can be used in simulation and optimization instead of the original (large) system. In general, the study aims to find a reduced model for a given switched system with a fixed switching signal and known mode sequence. This research concerns first the reduced realization of switched systems with known mode sequence which has the same input-output behavior as original switched systems. Secondly, a model reduction method is proposed for switched systems with known switching signals which provide a good model with suitable thresholds for the given switched system.

Title: Potential of Locally Synthesized Nanomaterials in Multifunctional Applications

Abstract:  The physico-chemical properties of materials at the nanoscale can be tuned as desired by controlling their structure, size, and shape via the appropriate choice of synthesis techniques and conditions. Over the past few years, there has been an upsurge in the development of new synthesis techniques and optimization of the conditions of the existing ones. We have developed cost effective low temperature techniques to synthesize undoped, rare earth doped and 2D materials incorporated bismuth ferrite nanostructures. Very recently, we have synthesized metal halide perovskites using a facile hot injection technique. The synthesis of a number of perovskite nanomaterials and their structural, chemical and magnetic properties will be presented, along with their applicability for efficient photodegradation of industrial dyes and pharmaceutical wastes under solar light irradiation.

Title: Prediction of Conduction Velocity Distribution of Motor Nerve Fibers from Compound Muscle Action Potential

Abstract: Prediction of motor nerve conduction velocity distribution (CVD) from compound muscle action potential (CMAP), also known as the inverse problem of nerve conduction, is one of the effective tools for assessing the peripheral neuropathies by evaluating the electrophysiological characteristics of the peripheral nerves. Recent studies have utilized a continuous approach to solve the inverse problem exploiting the least square method. We assume that different metaheuristic algorithms could be utilized to solve not only the inverse problem of nerve conduction, but also predict the motor unit action potential (MUAP) signal. We have utilized a piecewise Hermite polynomial function to design the MUAP waveform and a modified single Weibull function to model the CVD of human median nerves. Our new framework produced the optimal parameter values that produce the predicted CVD and MUAP which result in generating a CMAP signal that closely correlates the corresponding collected CMAP signal. The inverse approach presented in this study may provide an effective non-invasive alternative tool to deal with this ill-conditioned inverse problem of motor nerve conduction.

Title: Bifurcation Analysis of Periodic Traveling Wave Solutions in Excitable Reaction-Diffusion Systems

Abstract: In this talk, I will show the existence and stability of periodic traveling waves (PTWs) in two- variable excitable reaction-diffusion systems. We introduce a system of reaction-diffusion equations to mimic the excitability of cardiac cells. Our results show two types of bifurcations in the periodic traveling waves. The Eckhaus and Hopf bifurcations are two basic bifurcations in the PTWs. There are two families of PTWs: fast and slow. The first one is stable in the case of the standard FitzHugh-Nagumo excitable system. However, we observe that it becomes unstable in our model and bifurcates to an oscillating wave. We explain this phenomenon by numerically calculating the essential spectra of the periodic traveling waves. In addition, the standard FitzHugh-Nagumo model cannot capture the irregular action potentials of sufficiently large periods in a one-parameter family of solutions. Motivated by this, we propose a modified FitzHugh-Nagumo reaction-diffusion system by changing its recovery kinetics. We find that the PTWs of sufficiently large periods cross the stability boundary. Moreover, we observe a reasonable agreement between the direct PDE simulations and the solutions in the traveling wave ODEs. In two dimensions, we study the spiral wave instability that agrees with the waves observed in cellular activity.

Title: Impact of Hemodynamic Properties in Coronary Main Artery Disease Based on Biomedical Imaging

Abstract:  A conventional invasive catheterization procedure is currently used to detect atherosclerotic severity in coronary arteries. However, it is still challenging to measure multiple consecutive stenoses (MCS) in coronary main arteries, a severe condition, by using the invasive method. In this paper, we report important haemodynamic properties like the wall shear stress (WSS) and velocity magnitude across different luminal areas of coronary stenosis in patient-based right coronary artery models of MCS using pulsatile heart flow simulations. The WSS and velocity magnitudes in blood flow simulations of different degrees of stenosis indicated a relationship between the proximal moderate stenosis and the distal severe stenosis models. We have adopted open-source tools for different stages of this computational method. The results show the physical effects of different haemodynamic factors including velocity magnitude, mean arterial pressure difference, WSS and virtual fractional flow reserve (vFFR), which allow for predicting the physiological computation in the MCS models conditions. This study identifies fundamental physics critical for haemodynamic function and indicates the impact of these factors on vFFR measurements. These findings provide insight into and improvement of the pathophysiological assessment of MCS. The results reveal haemodynamic properties which can be used to diagnose coronary irregularities using a visualization method.

Title: Interaction of Ocean waves in a multi-layer shallow water system with topography

Abstract: Mathematical modeling of ocean waves is based on the formulation and solution of the appropriate equations of continuity, momentum, and the choice of proper initial and boundary conditions. Many free surface water waves can be approximated by using the shallow water equations (SWE) under the influence of gravity, with the assumption that the wave's horizontal length scale is considerably bigger than the depth scale and the wave height is much less than the fluid's mean depth. Furthermore, the three-dimensional flows in hydrostatic and Boussinesq limits can be described by the multi-layer shallow water equation, in which the fluid is discretized horizontally into a set of vertical layers, each with its own height, density, horizontal velocity, and geopotential. This work presents a two-dimensional version of DYNAMICO method and compares it with one-dimensional SWE. The equations are discretized using a Lagrangian vertical coordinate system which does not allow the mass to flow across the vertical layers. An explicit staggered finite volume method has been used to solve the single and multi-layer SWE, with and without density stratification and topography. The Lagrangian vertical grid is remapped using an arbitrary Lagrangian-Eulerian (ALE) algorithm onto the initial σ-z based coordinates as necessary. A low-storage explicit fourth-order Runge–Kutta scheme is used for time integration. The phase speed and wave characteristics of multi-layer SWE surface waves with and without density stratification are compared to those of single-layer SWE surface waves. In addition, the model is validated by comparing the numerical results with the analytical solutions of linearized two-layer SWE. The result confirms the accuracy of the model. A series of numerical experiments are presented to explain the dynamics and interactions between the surface waves and internal waves of the Ocean.

Title: The role of Galactic Dynamics on Star Formation.

 

Abstract: The Milky Way, our cosmic residence,    is one of the most studied yet enigmatic celestial structures.    To understand the formation and evolution of the Galaxy,    we require detailed knowledge of the star formation process.    To this end, we studied a large sample of 500 star-forming    dense molecular clumps near the Galactic center, focussing     on a detail understanding of the role of large scale Galactic    dynamics on star formation. We obtain that the spectral and    physical characteristics of these clumps are strongly coupled with the Galactic dynamics, for instance, i) three clump    clusters near the Galactic center are affected by the Galactic    bar shock, resulting in their emission line broadening,    ii) high mass clumps are mostly located on the Galactic    spiral arms, which may be attributed to an impact of   spiral density waves, and iii) low mass clumps are    ubiquitous on the Galactic plane. In addition, based    on the outcomes obtained from spectral analysis,    we developed a supervised convolutional neural    network that classifies the star forming clumps with 90% accuracy. Currently,    we are developing an unsupervised machine learning architecture, a self organising map,    to classify molecular clumps based on their spectral distributions on the sky.

Title: Time delay coordinates for Dynamic Mode Decomposition.

• Speaker: Dr. Shariful Islam, Assiatent Professor, Dept. of Mathematics and Physics, North South University.

• Abstract:  Dynamic Mode Decomposition (DMD) is a data-driven modeling technique used to
  extract dynamic features in a complex physical system from time-series data. We review the
  algorithm and establish its connection to the Koopman operator and Proper Orthogonal
  Decomposition. The performance of DMD depends on factors like the nature of the data, size of
  the data, and noise present in the data. In this talk, I will show how time delay coordinates have
  been used as a modification in the DMD algorithm to deal with data that has a highly oscillatory
  flow and then demonstrate the method on data acquired from a compressible signal. This version
  of DMD perfectly captures the dynamics and results in a reliable model for future prediction.
