Size and topology optimization of trusses with discrete variables
can be regarded as a kind of combinatorial optimization problem, because its solution space is disjoint and nonconvex, and feasible solution set is discrete.
i) The treatment of [r.sup.*] as a discrete variable
Type of landowner was represented as a discrete variable
. Previous hypothesis testing found there to be a difference in stewardship based on landowner or landlord type.
We created discrete variables
measuring whether respondents ever spent time in each activity, and variables measuring hours per week spent on each activity.
A discrete variable
model does facilitate numeric solutions that, by means of a direct approximation of a stochastic process, enable the analysis of interactively specific situations by virtue of a Monte Carlo simulation.
RECreg a discrete variable
for investment recommendations made by regional brokerage firms; it is equal to 3 for a buy, 2 for a hold, or 1 for a sell;
That's because the indepedent variable (type of activity) is a discrete variable
, a variable that has levels which are distinct and unconnected.
This study reports an analysis based on a cross-section of banking markets in which entry is treated as a discrete variable
with a Poisson distribution.
Seat Belt Use Discrete variable
for seat belt use: (0) no seat belt use; (1) yes, but rarely; (2) yes, some of the time; (3) yes, all the time.
in the space [L.sub.2] (h[R.sup.m]) [equivalent to] [l.sup.2] of functions [u.sub.d] of a discrete variable
[mathematical expression not reproducible].
(ii) Discrete Variable
. Discrete variables
correspond to variables that may have integer or binary values.
Their topics include discrete variable
structural optimization of systems under stochastic earthquake excitation, assessing the damage in inelastic structures under simulated critical earthquakes, the optimal seismic performance-based design of reinforced concrete buildings, an overall conceptual seismic design and local seismic capacity design for components of bridges, and the fuzzy identification of seismically excited smart systems.
