(industrial engineering)
A stress on the human body produced at the interface between the operator and the equipment during the use of hand tools or other equipment, and described in terms of direction and magnitude.

where [H] and [G] are NxN matrices, {[p.sub.s]} is the sound pressure vector, and {[v.sub.n]} is the surface velocity vector.
[p.sub.L] is used as the first-level virtual input and [e.sub.p] = [p.sub.L] - [p.sub.Ld] is used to describe the error between the desired pressure vector [p.sub.Ld] and the measured pressure vector [p.sub.L]:
The substitution of the specific numeric-model parameters outlined above has the net effect of mapping the dissipation relations from functions that depend on modified pressure differences,[DELTA][P.sup.i], to ones that depend on the system zone pressure vector,{p}, as, [G.sub.d.sup.i]([DELTA][p.sup.i])[right arrow] [G.sub.d.sup.i]({p}); hence, the mass conservation function for each zone, z, will also be dependent on the zone-node pressures as follows:
The Newton-Raphson method is a well-known method based on a truncated Taylor-series approximation of the system equations in an iterative manner where given an initial iterate for the zone pressure vector,[{p}.sub.[0]], an improved estimate is formed, [{p}.sub.[1]] = [{p}.sub.[0]] + [{[DELTA]p}.sub.[1]], by solving the truncated Taylor series approximation (Press et al.
where F, which may represent either one of the implicit constraints, is defined through a function G with implicit dependence on [phi] through the nodal pressure vector P and explicit dependence on the design [phi].
