Transient Analysis of MEP/MEP/1 Queues.

In this work we studied the Busy Period of a transient MEP/MEP/1 Queue where both the arrivals and service processes are allowed to be auto-correlated. Using linear algebraic queueing theory as our main analytical tool we studied the probabilities for serving ‘n’ customers in a busy period and the distributions for the busy period lengths. We also studied certain related first passages for higher level transitions, both for the finite and the infinte queueing situations.

Research Assistant May’03 –Dec ’03

School of Computing and Engineering, UMKC Funded by NSF

Modeling and Performance Analysis of Sprint 3G Data-access module.

We studied data access patterns arriving at multiple Sprint 3G data-warehouse sources connected via various middleware solutions. Performance models of the system were developed to study CPU utilizations to analyze certain anomalous behavior observed in pre-production environment.

Web Programmer Jan’02 – Dec ’02

School of Computing and Engineering, UMKC

Developed dynamic web pages with capabilities to conduct and grade exams on the fly as a part of a broad system migration that I did when changing the departments “Computer Survival and Applications” course from an old server onto an Apache server. Re-designed some older code base for efficiency with respect to database operations.

Platform: Java, Servlets, JSP, MS Access.
