(1978)
The theory of geometric programming is extended to include a new function with logarithmic exponents. The function, defined as a Quadratic Posylognomial (QPL) is a series of nonlinear product terms with positive coefficients ...
Multiporous plate sensilla in parasitic hymenoptera: their ultrastructure and phylogenetic relationship
(1978)
Hymenopterous parasites perceive stimuli in their environment primarily via sensory sensilla on their antennae. The ultrastructure of multiporous plate sensilla (MPS) was studied in the Ichneumonoidea and the Chalcidoidea. ...

(1978)
The purpose of this study was to generate data which would provide an enlarged empirical base for Systematic Training in Effective Parenting (STEP), an Adlerian based parent study program. The major objective of the study ...
Styles of deformation in the ramp regions of overthrust faults
(1978)
The presently available and widely used model describing the style of deformation of rocks in ramp regions of overthrust faults is that proposed by Rich (1934) for the Pine Mountain overthrust in the southern Appalachian ...
Effects of selected resource attributes on discrimination learning
