Abstract:
A design optimization system and method includes recursive evaluation of a system model and/or a set of subsystem models using subsystem design(s) to extract interactions and perform subsystem design optimization. Selective update of the boundary conditions occurs according to: where û(x,y,z,t) are the interactions between subsystems and/or between the system and its subsystem(s) on Γat iteration s, and {tilde over (w)}(x,y,z,t) are weight functions whose spatial and temporal distributions are predetermined and whose magnitudes are varied stochastically within a selected range.
Noise-Attenuating Laminate Composite Wallboard Panel And Methods For Manufacturing Same
A laminate composite wallboard panel is disclosed having multiple layers whose cross sections may contain internal and external non-uniformities and whose surfaces may be rough and non-uniform. The wallboard panel is similar in size and weight to a standard gypsum panel and can be handled and installed in a manner similar to such a panel. The wallboard panel also provides high degrees of noise attenuation, thermal insulation, fire resistance, shear strength, mold resistance and moisture resistance.
