This study investigated the feasibility of using an electron beam (EB) process to cure chemically impregnated wood products. Maple wood planks were impregnated with the low-viscosity resins 1,6 hexanediol dimethacrylate (HDDA) and trimethylolpropane trimethacrylate (TMPTA). The addition of nanoparticles into the formulation was also studied. The impregnated wood was then cured by EB irradiation...

This paper uses the mathematical software Maple for the auxiliary tool to study the differential problem of two types of functions. We can obtain the closed forms of any order derivatives of these two types of functions by using Euler's formula, DeMoivre's formula, finite geometric series and Leibniz differential rule, and hence greatly reduce the difficulty of calculating their higher order de...

This document is a hands-on of Maple worksheet for automatic code generation and simulation system for nonlinear model predictive control (NMPC) . This method is well known as a fast algorithm and expected to real-time implementation in a system. This describes the components and usage of the automatic code generation system named "AutoGenU for Maple". This worksheet is required Maple 17 or lat...

We demonstrate how a new data structure for sparse distributed polynomials in the Maple kernel significantly accelerates several key Maple library routines. The POLY data structure and its associated kernel operations (degree, coeff, subs, has, diff, eval, ...) are programmed for high scalability with very low overhead. This enables polynomial to have tens of millions of terms, increases parall...

In the Great Lakes region, little data exist on the distribution of exotic earthworm species or their relative impacts to soil structure and plant communities in forest types other than those dominated by sugar maple. Our objective was to document the earthworm populations in relation to their proximity to human development (e.g., campgrounds, boat landings, roads) in beech-maple dominated fore...

In the present paper a realization of a classical method for Lyapunov quantities computation in Maple is considered. Key–Words: Lyapunov quantity, focus values, symbolic computation, small-amplitude limit cycles, Maple, Hilbert 16th problem

T latest release of Maple V has had little time to be installed on many University teaching networks, least of all my own! So this review is mainly a report on what the improvements and the new features may have the potential to offer for those contemplating making the upgrade from Release 4, or as a change of teaching software for those who use one of its competitors. For certain comparative p...

During our systematic search for natural product-based anti-protein misfolding agents for the putative treatment of Alzheimer’s disease (AD), we investigated maple syrup. Canada is the world’s largest producer of maple syrup, accounting for 80% of global output; 2013 annual production was 46 million litres. Maple syrup is produced by thermal evaporation of the sap from maple (Acer) trees, a pro...
