Adler, Frederick R. | Aggregation and stability in parasite-host models | This paper generalizes the two-dimensional approximation of models of macroparasites on homogeneous populations developed by Anderson & May (1978), focusing on how the dispersion (the variance to mean ratio) of the equilibrium distribution of parasites on hosts is related to the stability of the equ... | Aggregation; Stability; Host-parasite models | 1992-04 |

Ogburn, Joyce L. | Bit by bit: digitizing information | Bit by Bit column: "Librarians began to explore the technologies that allow printed materials to be converted to a digitized form in the 1980's. This technology essentially turns a printed original work into a computerized image. Although the technology is not new, it is only recently that it has be... | Digital technology; Digital holdings, libraries | 1992-04 |

Christensen, Douglas A. | Extending the two-dimensional FDTD method to hybrid electromagnetic systems with active and passive lumped elements | This paper extends the finite-difference time-domain (FDTD) method to include distributed electromagnetic systems with lumped elements (a hybrid system) and voltage and current sources. FDTD equations that include nonlinear elements like diodes and transistors are derived. Calculation of driving-p... | Finite-difference time-domain method; Lumped elements | 1992-04 |
