Engineering (miscellaneous)Computer Science (miscellaneous)
Physics, medicine, astronomy -- these and other hard sciences share a common need for efficient algorithms, system software, and computer architecture to address large computational problems. And yet, useful advances in computational techniques that could benefit many researchers are rarely shared. To meet that need, Computing in Science & Engineering presents scientific and computational contributions in a clear and accessible format. The computational and data-centric problems faced by scientists and engineers transcend disciplines. There is a need to share knowledge of algorithms, software, and architectures, and to transmit lessons-learned to a broad scientific audience. CiSE is a cross-disciplinary, international publication that meets this need by presenting contributions of high interest and educational value from a variety of fields, including—but not limited to—physics, biology, chemistry, and astronomy. CiSE emphasizes innovative applications in advanced computing, simulation, and analytics, among other cutting-edge techniques. CiSE publishes peer-reviewed research articles, and also runs departments spanning news and analyses, topical reviews, tutorials, case studies, and more.

The right angle: precise numerical orthogonality in eigenstates
Tập 4 Số 5 - Trang 91-97 - 2002
Solutions of the Schrodinger equation that pertain to different energies are orthogonal by virtue of quantum dynamics. However, when we obtain such solutions numerically using library differential equation solvers, and when the inner product is defined by numerical quadrature, the result is not sufficiently orthogonal for certain purposes. This paper shows how to construct stable finite-difference schemes that preserve accurate numerical orthogonality of the solutions.

Designing scientific components
Tập 4 Số 5 - Trang 84-90 - 2002
Correctness is more precious to scientific programmers than it is to business programmers because of the great difficulty in distinguishing between programming errors, errors in modeling, and errors in algorithms. We've all sat in meetings and discussed whether a peculiar wiggle in a graph represents an algorithm problem (such as neglecting to include a possibly negligible term) or a modeling one (such as ignoring a possibly important physical process). Usually it turns out to be nothing so esoteric: we come back the next week and learn that it was a bug.

Web delivery of interactive laboratories: comparing three authoring tools
Tập 4 Số 5 - Trang 74-78 - 2002
As educators know, the more a student interacts with a subject, the better he or she will learn it. This is particularly true in technical subjects. One way to promote interaction is to have "laboratories" in which the student manipulates objects on the computer screen using the keyboard or mouse and then sees those actions' outcome.

Message passing: from parallel computing to the grid
Tập 4 Số 5 - Trang 70-73 - 2002
Over the past decades, the computational science community has debated the best architecture for parallel computing. However, experience has found there is an almost irreconcilable difference between the way users would like to write their software and the way machines must be instructed to run efficiently. The use of message passing in parallel computing is a reasonable decision, because the resultant code probably runs well on all architectures. This choice is not a trivial decision: it requires substantial work over and above that needed in the sequential case.

Testing and evaluating atmospheric climate models
Tập 4 Số 5 - Trang 64-69 - 2002
Model validation is a crucial process that underpins model development and gives confidence to the results from running models. This article discusses a range of techniques for validating atmosphere models given that the atmosphere is chaotic and incompletely observed.

Modeling chemical constituents of the atmosphere
Tập 4 Số 5 - Trang 56-63 - 2002
Interactions between the atmosphere, ocean, ice, land surface, and the marine and terrestrial biosphere control the global climate system. These components are coupled by the exchange of momentum, radiative energy, and trace constituents' mass. Various processes drive this exchange and require different computational methods to model it.
