Mathematics and Physics play an important role in understanding the fundamental laws of nature and it directly correlates the other fields of engineering and natural sciences. Understanding the importance and necessity of acquiring knowledge about the most exciting and interesting branch of science and engineering, Department of Mathematics and Physics belongs to the School of Engineering and Physical Sciences.
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. All our faculty members are highly qualified and they are responsible for teaching the Mathematics, Physics and Statistics courses offered by the University. Twelve of our sixteen fulltime faculty members are Ph.D. s from North America 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 all branches of stateofart research which include, but not limited to, the following topics:
Department of Mathematics and Physics (DMP), North South University (NSU), celebrated the pimoment 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 piday. 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 pimoment. This moment will come again in 2115, one hundred years later.
At this precise moment (according to Bangladeshtime) 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 Asaduzzaman. 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.

Tasmia Rahman Shahidi, from the department of ECE and Tasfea from Civil and Environmental Engineering, respectively won the 4th and 7th position in the 2nd Women's Mathematics Olympiad 2018. The competition was organised in cooperation with Department of Mathematics, the University of Dhaka and Women’s Mathematics Olympiad Committee and A. F. Mujibur Rahman Foundation. 180 students from 20 different universities from all over the country participated. Honourable faculty members from the Department of Mathematics, University of Dhaka judged the event. The winner from NSU has praised their faculties for being supportive and to encourage them to participate in such activities. Ms Tasmia said 'Mathematics is one of her favourite subjects and Dr. Hasina Akhter, faculty of Mathematics department at NSU specially guided her for the event. Rather than testing students’ ability to recall facts, the competition was designed to test students’ mathematical creativity and their ability to formulate and defend their conclusions. Every student has some potential abilities and skills, participating in different competitions is one of the ways to hone the skills and take one to the next level.
The Department of Mathematics and Physics is located on the 10^{th} floor of the SAC building. It does not offer an undergraduate degree like a Bachelor of Science degree in Mathematics or Physics yet. It is because the department came into existence only six months ago. However, the department serves a significant number of students through a wide range of service courses. It primarily imparts the mathematics and physics training for the undergraduate students of the university. The department also runs a thirty–credit minor program in mathematics.
Currently we have fulltime and parttime faculty members in our department. Ten of our thirteen fulltime faculty members are Ph.D. s from North America or Western Europe. The parttime 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. The breadth of expertise of our faculty members covers almost the entire range of mathematics and physics, pure as well as applied.
We have a plan to transform our department from present service position to a fullfledged 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: Efficient Reduced Order Modeling of Periodic Control Systems with Application to Circuit Problems.
Abstract:
In this seminar, we have presented a method for the model order reduction of continuous linear timevarying (LTV) periodic descriptor systems where the system's matrices are singular. This model order reduction strategy is based on the linear timeinvariant (LTI) reformulation of the LTV model through suitable discretization scheme. The resulting linear timeinvariant (LTI) system is then reduced using balanced truncation model reduction method. We use the LowRank Cholesky Factorized Alternating Directions Implicit (LRCFADI) iteration to approximate the solutions of the corresponding timeinvariant Lyapunov equations. Due to the singularity of the system's matrices, we have used the Pseudoinverses to find the optimal shift parameters that are used in LRCFADI approximation. The step responses, bode plots and eigenstructures of both the original and reduced system are compared to show the accuracy of the proposed model reduction approach.
