Nowadays computers can perform symbolic calculations--in addition to mere numerical computations for which they were originally designed--and this opens up exciting possibilities in structural engineering and mechanics. Until relatively recently, this computer-algebra option was hardly exploited exc

โฆ Synopsis
A set of REDUCE routines for manipulating operators which anticommute amongst themselves is described. These routines have applications in theories such as supergravity where anticommuting operators are used to represent ferminns. The Dirae bracket of the supersymmetry constraints arising in a quantum cosmological model based on N = 1 supergravity coupled to a massless scalar multiplet is calculated as an example.

Wave propagation due to longitudinal impacts on thin rods is a classical problem of mechanics, but only few completely analytical results for longitudinal wave propagation are available in literature. In this paper, it is shown that even such complicated impact problems can nowadays be solved using
A novel approach based on recursive symbolic computation is introduced for the approximate analytic solution of the Burgers equation. Once obtained, appropriate numerical values can be inserted into the symbolic solution to explore parametric variations. The solution is valid for both inviscid and v
We define a model of quantum computation with local fermionic modes (LFMs)-sites which can be either empty or occupied by a fermion. With the standard correspondence between the Foch space of m LFMs and the Hilbert space of m qubits, simulation of one fermionic gate takes O(m) qubit gates and vice v
## Abstract We investigate computable subshifts and the connection with effective symbolic dynamics. It is shown that a decidable ฮ ^0^~1~ class __P__ is a subshift if and only if there exists a computable function __F__ mapping 2^โ^ to 2^โ^ such that __P__ is the set of itineraries of elements of 2
In this paper we discuss the package DESOLV written for the algebraic computing system MAPLE. DESOLV has routines which will systematically obtain with considerably flexibility, all resulting integrability conditions for any system of linear, coupled, partial differential equations. It also contains
