302 Gordon Palmer HallTitle: Phantom Traffic Jams, Autonomous Vehicles, and the Future of Traffic Modelling Abstract: Initially homogeneous vehicular traffic flow can become inhomogeneous even in the absence of obstacles. In this "phantom traffic jam'' phenomenon, small perturbations grow into traffic waves, called “jamitons”. Via the mathematical analysis of traffic models, we demonstrate that phantom jams can arise from

We prove some embedding results and present a Riesz representation lemma in our setting . Also it shows an application of the latter result by characterizing the global Lipschitz Nemytskii operator on the newly introduced spaces

The solvation free-energy functional of all phase fields consists of the surface energy, solute excluded volume and solute-solvent van der Waals dispersion energy, and electrostatic free energy. The last part

The third annual Quad in Motion will take place from 8 a.m. to 4 p.m. Wednesday, Sept. 13, on the Quad. The Office of Health Promotion and Wellness wants all 6000+ employees to keep the Quad in Motion by walking or running for at least 30 minutes that day. Employees are asked to sign up
Applied Math Seminar – Xu Zhang, Mississippi State University
228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle: Immersed Finite Element Methods for Interface Problems Basic idea, Development, Analysis, and Applications Abstract: Simulating a multi-scale/multi-physics phenomenon often involves a domain consisting of different materials. This often leads to the so-called interface problems of partial differential equations. Classical finite elements methods can solve interface problems satisfactorily if the mesh is aligned with interfaces; otherwise the
