The question, as posed, is routine. However, in the course of implementing a solution in Maple, it quickly becomes apparent that this problem is a perfect vehicle to display the complementary roles of numerical, graphical, and analytical techniques in the solution of di erential equations. In this paper I will discuss how I use Maple to assist my students in the analysis of this problem. In par...

In this article we discuss the advantages (and pitfalls) in developing code optimization and Maple to C conversion programs for Maple procedures, specifically those required for numerical differential equation solution. Special treatment related to code optimization for large sets of equations is a major focus. Issues related to conversion of Maple code to C code are discussed, and finally a se...

Homogenization of forest stands with generalist species is a hallmark past disturbance and characterizes the Great Dismal Swamp (GDS), forested wetland in Atlantic Coastal Plain. Once mosaic communities, disturbances (e.g., timber harvesting ditching) have resulted altered hydrologic regimes communities. In response, restoration management aim to enhance community composition function. To infor...

In [3] closed formulae for the forward, backward and symmetric solutions of an ARMA–Representation have been presented. Here these formulae are implemented in the symbolic computational language MAPLE and corresponding MAPLE code is provided.

Overstory and understory data were collected over a 15-year period (1996–2011) before and after seed tree logging in 1996 and an accidental wildfire in 2006 in a young developing mixed-oak forest in central Pennsylvania. The mature forest overstory was dominated by chestnut oak (Quercus montana) followed by northern red oak (Quercus rubra), black oak (Quercus velutina), scarlet oak (Quercus coc...

Competition for nitrogen (N), particularly in resource-limited habitats, might be avoided by different N acquisition strategies of plants. In our study, we investigated whether slow-growing European beech and fast-growing sycamore maple seedlings avoid competition for growth-limiting N by different N uptake patterns and the potential alteration by soil N availability in a microcosm experiment. ...

Metabolic and physiological potential evaluator (MAPLE) is an automatic system that can perform a series of steps used in the evaluation of potential comprehensive functions (functionome) harboured in the genome and metagenome. MAPLE first assigns KEGG Orthology (KO) to the query gene, maps the KO-assigned genes to the Kyoto Encyclopedia of Genes and Genomes (KEGG) functional modules, and then ...

The maple-basswood community type has long been associated with the "Big Woods" of Minnesota and adjacent Wisconsin, although this community type also exists in discontinuous phases within surrounding forest types. This study looks at the apparent most northwestern outlier of the maple-basswood community type, Rydell National Wildlife Refuge (NWR) in Minnesota. Specific goals are (1) to determi...

Permanent plot records ranging from 13 to 42 years in duration were used to study understory development in four upland oak forests in Massachusetts and New York. All tracts have a dense understory of shade-tolerant species dominated by red maple (Acer rubrum L.) but sparse representation of oak saplings. Mortality rates for red maple have been low compared to other species, and maples have inc...
