10:00 AM - 12:00 PM	ELEC Research Component of PhD Qualifier Exam by Joshua Steakelum - ECE Department Location: Claire T. Carney Library, Room 314 Cost: Free Contact: > See Description for contact information Description: Topic: Multi-phase Algorithm Design for Accurate and Efficient Model Fitting Location: Claire T. Carney Library (LIB), Room 314 Zoom Conference Link: https://umassd.zoom.us/j/96312746810 Meeting ID: 963 1274 6810 Passcode: 161289 Abstract: Recent research applies soft computing techniques to fit software reliability growth models. However, runtime performance and the distribution of the distance from an optimal solution over multiple runs must be explicitly considered to justify the practical utility of these approaches, promote comparison, and support reproducible research. This paper presents a meta-optimization framework to design multi-phase algorithms for this purpose. The approach combines initial parameter estimation techniques from statistical algorithms, the global search properties of soft computing, and the rapid convergence of numerical methods. Designs that exhibit the best balance between runtime performance and accuracy are identified. The approach is illustrated through nonhomogeneous Poisson process and covariate software reliability growth models, including a cross-validation step on data sets not used to identify designs. The results indicate the nonhomogeneous Poisson process model considered is too simple to benefit from soft computing because it incurs additional runtime with no increase in accuracy attained. However, a multi-phase design for the covariate software reliability growth model consisting of the bat algorithm followed by a numerical method achieves better performance and converges consistently, compared to a numerical method only. The implementation of a framework-designed algorithm into a software reliability tool is demonstrated. The proposed approach also supports higher-dimensional covariate software reliability growth model fitting suitable for implementation in further tools.

1:00 PM - 2:00 PM	Physics Master of Science Research Project by Samruddhi R. Shinde Location: > See description for location Contact: Physics Department Description: Topic: Study of Interplanetary Optimization between Earth and Mars Location: SENG -201 Abstract: Astrodynamics-based trajectory planning, and optimization are vital in deep space exploration mission design. Interplanetary Trajectories are the orbital paths that a spacecraft takes between a starting and destination celestial body at a certain point in time. Maximum final mass and minimal travel time are two primary parameters that are always targeted to be optimized in Interplanetary trajectory. We focused on the time aspect in our study as it is very crucial when planning any interplanetary space trip. The track between Earth and Mars from 2020 to 2050 is shown using a trajectory optimization tool. The trajectory optimization tool is based on a genetic algorithm and determines trajectories using a patched conics approximation. Time of Flight (TOF), Departure C3 energy, Arrival Velocity, and the orbital elements of the proposed orbit are the tool's output parameters. To select an orbit for Earth to Mars, we focused on getting TOF, C3 Energy, and arrival velocity in the acceptable range. Further, we utilized two open-source libraries, Pykep and PyGMO, to validate the findings achieved using the optimization tool. The outcomes were the journey time, Arrival Vinf, Departure Vinf and Insertion DV. The two approaches were evaluated in terms of trajectory view and travel time. Between the two methods, there is a significant difference in travel duration observed. The best ideal year between 2020 and 2050 will be chosen after comparing the results of the trajectory plotted and TOF obtained from the optimization tool and Pykep library used.

8:00 AM - 10:00 AM	Physics Master of Science Thesis Defense by Miriya Jones Location: > See description for location Contact: Physics Department Description: Topic: 3D Hydrodynamical Simulations of Merging One-CO White Dwarf Binaries Location: SENG 201 Abstract: In 1181, "a guest star", as bright as the planet Saturn was observed in the sky by Chinese and Japanese astronomers. A recent study has identified the star IRAS 00500 + 6713 as the remnant from the 1181 event, surrounded by the nebula "PA 30" and pointing to an unusual scenario where the explosion could have been caused by the merger of two white dwarfs. In this thesis, I will present a 3D hydrodynamical simulation model for SNe Iax in the context of the double-degenerate channel of merging ONe- CO white dwarf binary using the adaptive mesh refinement hydrodynamics code FLASH. I will discuss the explosion mechanism, the characteristics of the remnant, and other implications of this model.

Despite their significance, the driving mechanisms behind SNe Ia are yet to be fully confirmed. The dynamically driven double-degenerate double-detonation (D6) scenario has gained traction as the most likely explanation for nine hypervelocity galactic white dwarfs discovered by the ESA Gaia space mission. In this thesis, I will present a comparative analysis of hydrodynamical simulations of D6 SNe Ia using two leading hydrodynamical simulation frameworks: AREPO, which utilizes an unstructured, Voronoi tessellation dynamic moving mesh, and FLASH, with its structured adaptive Eulerian mesh. I will briefly describe the impact of our findings on the physical processes which give rise to SNe Ia.

LOCATION: Zoom link: https://umassd.zoom.us/j/93989772725?pwd=Ulk5ME9KYnpvMGhBU2toZ1dKeHE3dz09 (Contact scunha@umassd.edu for Meeting ID# and Passcode) TOPIC: Ion Beam Figuring Prototype for Guiding the Polishing Process of Optical Substrates ABSTRACT: For high efficiency optical components, substrate surface smoothness is critical. This project aims to create a polishing method for substrates that can be performed at Plymouth Grating Laboratory, for the purpose of creating ultra-high efficiency diffraction gratings. Traditional polishing methods, such as pitch polishing and lap polishing, use an abrasive slurry to mechanically smooth substrate surfaces. This method can be quite expensive and often fails for large scale optics. Therefore, a non-mechanical polishing technique called Ion Beam Figuring is proposed as an alternative method for substrate polishing. This method can be achieved on site at Plymouth Grating Laboratory while simultaneously reducing cost and increasing the likelihood of a successful polish. To achieve this method of polishing, a framework is developed for experimentally profiling a radio frequency ion source, via broadband spectroscopy. Next, a prototype 1-dimensional Ion Beam Figuring method is created using a custom MATLAB program. This program yields a dwell time map, which guides the figuring process by determining the position and time for which the ion beam etches the substrate. This prototype Ion Beam Figuring program will be based on a Fourier transform deconvolution method. Once this program was created, initial validations were performed using test case surface profiles to ensure the program properly computes parameters used in the IBF process. This project provides a foundation to produce large polished substrates with higher reliability and a significantly decreased cost. This is a key step in creating high efficiency meter class diffraction gratings to be used in some of the highest power laser systems in the world. These laser systems can be used in fusion, biomedical, defense, and semiconductor industries.
