ARISE: American renaissance in science education

Description: The national standards and state derivatives must be reinforced by models of curricular reform. In this paper, ARISE presents one model based on a set of principles--coherence, integration of the sciences, movement from concrete ideas to abstract ones, inquiry, connection and application, sequencing that is responsive to how people learn.

The Fermilab computing farms in 1997

Description: The farms in 1997 went through a variety of changes. First, the farms expansion, begun in 1996, was completed. This boosted the computing capacity to something like 20,000 MIPS (where a MIP is a unit defined by running a program, TINY, on the machine and comparing the machine performance to a VAX 11/780). In SpecInt92, it would probably rate close to 40,000. The use of the farms was not all that large. The fixed target experiments were not generally in full production in 1997, but spent time tuning up code. Other users processed on the farms, but tended to come and go and not saturate the resource. Some of the old farms were retired, saving the lab money on maintenance and saving the farms support staff effort.

Culturally relevant science: An approach to math science education for hispanics. Final technical report

Description: This progress report summarizes results of a teacher workshop. A letter sent to 17 teachers who had participated in the workshop requested a report of any activities undertaken and copies of lesson plans and materials developed. Only nine responses were received, and not all of them demonstrated a satisfactory level of activity. Teachers who submitted materials showing the most promise were invited to participate in the Summer Writing Workshop. A partial first draft of a companion volume for the teacher`s manual was written which provides a rationale for culturally relevant science and presents the cultural and scientific background needed. The outline of the book is presented in Appendix 1. Appendix 2 is a sample chapter from the book.

MGMRES: A generalization of GMRES for solving large sparse nonsymmetric linear systems

Description: This paper is concerned with the solution of the linear system Au = b, where A is a real square nonsingular matrix which is large, sparse and nonsymmetric. We consider the use of Krylov subspace methods. We first choose an initial approximation u{sup (0)} to the solution {bar u} = A{sup -1}b. The GMRES (Generalized Minimum Residual Algorithm for Solving Non Symmetric Linear Systems) method was developed by Saad and Schultz (1986) and used extensively for many years, for sparse systems. This paper considers a generalization of GMRES; it is similar to GMRES except that we let Z = A{sup T}Y, where Y is a nonsingular matrix which is symmetric but not necessarily SPD.

Fourier analysis

Description: What follows is a description of my analysis. First, the FFT that I use is described on the attached pages. Note that the scaling factor for the forward transform is 1/N. I compute the following rms values: rms(original data) = 64.9463 nm; rms(data*hanning) = 55.7723 nm (before renormalization). The use of the hanning filter is accompanied by a renormalization to insure that the rms value is maintained. I also fit to the curvature of the scan. The data corrected for focus gives the following rms values: rms(corrected data) = 56.8835 nm; rms(corrected data*hanning) = 53.2179 nm (before renormalization). The PSD is shown for various data. The PSD is calculated as: PSD = | FFT(y) | {sup 2} * xl where xl is the length of the x axis, 45.9952. I did find an error in the plot that you were sent. If kx is the frequency axis, i.e., values from (0,Nyquist), then kx(l,Nyquist) is plotted versus PSD(0,Nyquist). This error is corrected in the attached plots. The plot you have appears to be the PSD of the original data with no hanning applied. The removal of the quadratic term appear to have a negligible effect on the PSD. It changes only the first couple of terms (which lie outside of the data valid range). The removal of the center feature has a much stronger effect.

Go ahead, visit those web sites, you can`t get hurt, can you?

Description: Browsing (surfing) the World Wide Web (the web) has exploded onto the Internet with an unprecedented popularity. Fueled by massive acceptance, the web client/server technology is leaping forward with a speed that competes with no other software technology. The primary force behind this phenomenon is the simplicity of the web browsing experience. People who have never touched a computer before can now perform sophisticated network tasks with a simple point-and-click. Unfortunately, this simplicity gives many, if not most, web wanderers the impression that the web browser is risk free, nothing more than a high powered television. This misconception is dangerous by creating the myth that a user visiting a web site is immune from subversive or malicious intent. While many want you to believe that surfing the web is as simple as using any other household appliance, it is not like surfing television channels, it is bi-directional. You can learn a lot of useful information from web sites. But, either directly or indirectly, others can also learn quite a bit about you. Of even more concern is a web sites` potential ability to exert control over the local computer. This paper tries to consolidate some of the current concerns that you should consider as you jump into the surf.

A Feature Extraction Toolbox for Pattern Recognition Application

Description: Feature extraction and evaluation are procedures common to the development of all pattern recognition application. These features are the primary pieces of information used to train the pattern recognition engine, whether that engine is a neural network, a fuzzy logic rulebase, or a genetic algorithm. Careful selection of the features to be used by the pattern recognition engine can significantly streamline the overall development and training of the solution for the pattern recognition application. Presently, AlliedSignal Federal Manufacturing & Technologies (FM&T) is developing an integrated, computer-based software package, called the Feature Extraction Toolbox. This package will be used for developing and deploying solutions to generic pattern recognition problems. The toolbox integrates a variety of software techniques for signal processing, feature extraction and evaluation, and pattern recognition, under a single, user-friendly developmental environment. While a feature extraction toolbox can help in the selection process, it is the user that ultimately must make all decisions. A prototype version of this toolbox has been developed and currently is being used for applications development on several projects in support of the Department of Energy. The toolbox has been developed to run on a laptop computer so that it can be taken to a site and used in the field.

Determining training needs from supervisors` assessment of staff proficiency in tasks and skills

Description: To provide the basis for establishing training opportunities, this project investigated supervisors` views of three components of staff activities. The project established the tasks that staff perform, identified staffs level of effectiveness in performing these tasks, and investigated staffs level of proficiency in performing the skills underlying these tasks. Training opportunities were then determined in those areas where knowledge and skins could be improved for staff to perform their tasks more effectively. Staff currently perform their tasks sufficiently well. Furthermore, supervisors indicated that for the most part staff do perform the tasks they should perform. In carrying out these tasks, staff use primarily critical thinking, problem solving, and communication skills rather than discipline-specific skills. Although staff generally have working knowledge of most of these skills, additional training in critical thinking and problem solving, program and project management techniques, and communications is appropriate to further improve the organizations effectiveness.

A path-following interior-point algorithm for linear and quadratic problems

Description: We describe an algorithm for the monotone linear complementarity problem that converges for many positive, not necessarily feasible, starting point and exhibits polynomial complexity if some additional assumptions are made on the starting point. If the problem has a strictly complementary solution, the method converges subquadratically. We show that the algorithm and its convergence extend readily to the mixed monotone linear complementarity problem and, hence, to all the usual formulations of the linear programming and convex quadratic programming problems.

Computational experience with a dense column feature for interior-point methods

Description: Most software that implements interior-point methods for linear programming formulates the linear algebra at each iteration as a system of normal equations. This approach can be extremely inefficient when the constraint matrix has dense columns, because the density of the normal equations matrix is much greater than the constraint matrix and the system is expensive to solve. In this report the authors describe a more efficient approach for this case, that involves handling the dense columns by using a Schur-complement method and conjugate gradient interaction. The authors report numerical results with the code PCx, into which the technique now has been incorporated.

Single identities for lattice theory and for weakly associative lattices

Description: We present a single identity for the variety of all lattices that is much simpler than those previously known to us. We also show that the variety of weakly associative lattices is one-based, and we present a generalized one-based theorem for subvarieties of weakly associative lattices that can be defined with absorption laws. The automated theorem-proving program OTTER was used in substantial way to obtain the results.

The ANL/IBM SP scheduling system

Description: Approximately five years ago scientists discovered that modern UNLX workstations connected with ethernet and fiber networks could provide enough computational performance to compete with the supercomputers. As this concept became increasingly popular, the need for distributed queuing and scheduler systems became apparent. Systems such as DQS from Florida State University were developed and worked very well. Today however, supercomputers such as Argonne National Laboratory`s IBM SP system can provide more CPU and networking speed than can be obtained from these networks of workstations. Nevertheless, because modern super computers look like clusters of workstations developers felt that the scheduling systems previously used on clusters of workstations should still apply. After trying to apply some of these scheduling systems to Argonne`s SP environment it became obvious that these two computer environments have very different scheduling needs. Recognizing this need, and realizing that no one has addressed it, we at Argonne developed a new scheduling system. The approach taken in creating this system was unique in that user input and interaction were encouraged throughout the development process. Thus a scheduler was built that actually works the way the users want it to.
