Automated, Web-Based, Second-Chance Homework, Randall W. Hall, Leslie G. Butler, Saundra Y. Mcguire, Sean P. Mcglynn, Gary L. Lyon, Ron L. Reese, Patrick A. Limbach Nov 2001

Automated, Web-Based, Second-Chance Homework, Randall W. Hall, Leslie G. Butler, Saundra Y. Mcguire, Sean P. Mcglynn, Gary L. Lyon, Ron L. Reese, Patrick A. Limbach

Randall W. Hall

Procedures and programs for Web-based homework administration were developed and tested. The special feature of the protocol is the option of a "second chance". When a student gives a wrong answer in the weekly homework assignment, a second version of the same question is posed to that student within 48 hours. Both the original and the second versions of the homework are Web-based and automatically graded. More than 90% of the students used the second chance at least once during the semester. More than 60% used this feature for every homework assignment. The second-chance option motivates students to study the …


Estimation Of Error In Large Area Underwater Photomosaics Using Vehicle Navigation Data, C. Roman, H. Singh Oct 2001

Estimation Of Error In Large Area Underwater Photomosaics Using Vehicle Navigation Data, C. Roman, H. Singh

Christopher N. Roman

Creating geometrically accurate photomosaics of underwater sites using images collected from an AUV or ROV is a difficult task due to dimensional errors which grow as a function of 3D image distortion and the mosaicking process. Although photomosiacs are accurate locally their utility for accurately representing a large survey area is jeopardized by this error growth. Evaluating the error in a mosaic is the first step in creating globally accurate photomosaics of an unstructured environment with bounded error. Using vehicle navigation data and sensor offsets it is possible to estimate the error present in large area photomosaics independent of the …

Opportunities In Computational Materials Science, Randall Hall, Juana Moreno Sep 2001

Opportunities In Computational Materials Science, Randall Hall, Juana Moreno

Randall W. Hall

The White House Materials Genome Initiative intends to double the speed with which we discover, develop, and manufacture new materials. In order for this initiative to be successful an unprecedented collaboration between computer scientists, applied mathematicians, computational scientists, and engineers with expertise in each of the aspects of the simulation-guided design of modern materials must be established. We must also take advantage of the enormous national investments in the next generation of hyperparallel, heterogeneous, multicore supercomputers to develop experimentally verified algorithms. In this talk I will describe new collaborative efforts in Louisiana towards developing a State-wise team of scientist to …

Spectra And Geometries Of Ar+ N (N = 30 - 60) [Invited], Jose Gascon, Randall W. Hall May 2001

Spectra And Geometries Of Ar+ N (N = 30 - 60) [Invited], Jose Gascon, Randall W. Hall

Randall W. Hall

We report finite temperature simulations of AR+n (N = 30−60) using a semiempirical model Hamiltonian. We calculate the photoabsorption spectra and analyze the charge distribution in both ground and excited states. The maximum photoabsorption wavelength for this set of clusters is in good agreement with experimental data. We analyze the average position of the atoms and the finite temperature distribution of the positive charge over the cluster. We find the charge localized on three atoms in the ground state and over the first two solvation spheres in the excited states. The extent of delocalization in the excited states can be …


Hermite Collocation Solution Of Partial Differential Equations Via Preconditioned Krylov Methods, Stephen Brill Feb 2001

Hermite Collocation Solution Of Partial Differential Equations Via Preconditioned Krylov Methods, Stephen Brill

Stephen H. Brill

We are concerned with the numerical solution of partial differential equations (PDEs) in two spatial dimensions discretized via Hermite collocation. To efficiently solve the resulting systems of linear algebraic equations, we choose a Krylov subspace method. We implement two such methods: Bi-CGSTAB [1] and GMRES [2]. In addition, we utilize two different preconditioners: one based on the Gauss–Seidel method with a block red-black ordering (RBGS); the other based upon a block incomplete LU factorization (ILU). Our results suggest that, at least in the context of Hermite collocation, the RBGS preconditioner is superior to the ILU preconditioner and that the Bi-CGSTAB …

Biorthogonal Wavelets With Certain Regularities, Tian-Xiao He Dec 2000

Biorthogonal Wavelets With Certain Regularities, Tian-Xiao He

Tian-Xiao He

In this paper, we will discuss the construction of biorthogonal wavelets that possess the largest possible regularities and required vanishing moments. For the sake of applications, we also give a general Daubechies’ iteration method of constructing biorthogonal wavelets by using biorthogonal splines.

Gyroscope Precession And General Relativity, Br Holstein Dec 2000

Gyroscope Precession And General Relativity, Br Holstein

Barry R Holstein

Precession of a gyroscope in the presence of a gravitational field is of considerable interest, on account of the soon to be launched satellite test and because of its connection to Mach's principle. Nevertheless, this topic is not generally covered in the curriculum because of the mathematical sophistication required. We examine some of the simple physics involved and argue that by examining simple graviton-elementary particle couplings one can easily understand this phenomenon.
