RESEARCH COMPONENT OF PHD QUALIFIER EXAM BY: MD Nashid Anjum
- Location: Science & Engineering Building, Lester W. Cory Conference Room: Room 213A
- Cost: Free
- Contact: ECE: Electrical & Computer Engineering Department
- Description: TOPIC: Co-Existence in Millimeter-Wave Wireless Body Area Network
LOCATION: Lester W. Cory Conference Room, Science & Engineering Building (SENG), Room 213A
ABSTRACT:
A WBAN consists of few wearable sensors attached to body parts, clothes, implanted underneath the skins or inner body. A WBAN consists of a central hub (i.e., base station) that controls and communicates with sensors. WBANs may deeply overlap on each other in a crowded area such as hospital because of their rapid mobility, small network size, flexible topology, and higher network density. This overlapping may raise severe interference issues. In case of deeply overlapping WBANs, interference avoidance employing power control schemes is plausibly unrealistic, because, nodes and hub from other network may stay much closer than nodes and hub of its own network. In this research work, we formulate the WBAN self-coexistence problem as a linear integer programming optimization problem considering service priorities and user demands and propose a solution named Fair Frame Distribution for Self-coexistence (FDS).
Further, I found that 60 GHz based communication is probably the best fit for WBAN compared to the traditional 2.4 GHz based communication considering its quality of compact network coverage, device miniaturization, efficient frequency reuse, multi-gigabyte transmission rate, and the therapeutic merits for human health. The efficiency of the mmWave based WBAN can be improved by allowing coexistence i.e., mitigating interference among the WBANs. We formulate the coexistence problem as non-cooperative, distributed power control game. The existence of Nash equilibrium is proved and the efficiency of the Nash equilibrium is improved by modifying the utility function and introducing a linear and an exponential pricing factor. Simulation result shows the proposed pricing policy significantly improves the efficiency of the optimal solution with respect to Pareto optimality and social optimality. To introduce different service priority levels such as delay sensitivity this research work utilizes the concept of discount factor employing repeated game. Though both of pricing and repeated game significantly improve the efficiency of the optimal equilibrium. This research work employed Nash bargaining solution to improve fairness of the optimal equilibrium. Extensive simulation result shows that Nash bargaining solution significantly improves the equilibrium efficiency and fairness.

TOPIC:
Investigating the Computational Efficiency of a Non-Hydrostatic Ocean Model on the Massachusetts Green High Performance Computing Center
ABSTRACT:
Scientists today use computer models to study oceanic variability. The majority of these models are still unable to capture all of the complex physical interactions that exist in the ocean. Improving the computational speed of these models remains a high priority. In this project, we use a three-dimensional non-hydrostatic ocean model which evolves momentum, temperature, and salinity in time. We explore the model performance for different grid sizes and compile-time options on the Massachusetts Green High Performance Computing Center. For smaller grid sizes we find serial computations (no OpenMP) faster than parallel computations with optimization level O3 for the Intel fortran compiler. Changing the optimization level to O2 gives superior performance for parallel compared to serial computations. For larger grid sizes however, there is no clear preference for serial or parallel. Amongst the serial runs, we find that increasing the number of threads from 4 to 10 improves the efficiency of the code regardless of the grid size. On the other hand, the parallel runs yield similar performance for both 4 and 10 threads. For smaller grids using 10 threads gave a better performance for parallel runs with optimization level O2 for the Intel fortran compiler. For larger grids, there was no trend with respect to the number of threads affecting the code efficiency. For the optimization level O3, both 4 and 10 threads resulted in almost similar performance regardless of the grid size.

Fine Arts Faculty Exhibition & Collaborative Aggregates Art Scholarship Exhibition
- Location: CVPA: College of Visual and Performing Arts
, 285 Old Westport Road, Dartmouth, MA
- Cost: free
- Contact: University Art Gallery
- Description: An exhibition of Fine Arts faculty at the College of Visual and Performing Arts presents recent faculty work in Painting, Drawing, Printmaking, Sculpture, and Mixed-Media at the UMass Dartmouth CVPA Campus Gallery from November 8 through December 12, 2016.
Also on display will be the Collaborative Aggregates Art Scholarship Exhibition. Collaborative Aggregates has awarded six $1,500 scholarships to students in the Department of Fine Arts enrolled in the graduate or undergraduate program: Henry Carpio, April Claggett, Devin Kish, Andrew Laverty, Allen TenBusschen, and Erin Wheary. Works by each scholarship winner will be included in the Collaborate Aggregates annual calendar and are also presented in this exhibition.
The mission of the Department of Fine Arts is to maintain an environment where artists are committed to the pursuit of teaching, research, and creative work. This faculty of professional artists provides a high-quality cross-disciplinary studio education to students at the foundation, undergraduate, and graduate levels through formal, aesthetic, technical, and intellectual training. Faculty members prepare students to become creative artists, pursue graduate study, or engage in Fine Arts-related professions through the attainment of their BFA and MFA degrees.
The closing reception will be held on Monday, December 12th, from 4 pm to 6 pm with artist talks at 5 pm.
