Abstract: This paper attempts to show that in the complex, interactive environment that managers face, the logical, rational, lineal mode of thinking needs to be complemented by arational, holistic, integrative modes. After the ...

Abstract: A five‐parameter constitutive equation for Ottawa sand at one void ratio is proposed. After an expression for the strain energy function in terms of the stretch ratios is obtained, the various constants in the constitutive ...

Abstract: In this paper, item (S2) of Section 3, page 464, should read2 ϕ(q,t)=0,ψ(q,q̇,t)=0, with ϕ(q0,0)=0,ϕ̇(q0,0)=0, and ψ(q0,q̇0,0)=0.

Abstract: The problem of estimating a space dependent coefficient in a forced linear hyperbolic differential equation from the knowledge of the solution at one or more isolated points is dealt with. The ...

Abstract: In this paper we develop an analytical set of equations to describe the motion of discrete dynamical systems subjected to holonomic and/or nonholonomic Pfaffian equality constraints. These equations ...

Abstract: The problem of optimally positioning sensors in lumped and distributed parameter dynamic systems for the purpose of system identification from time-domain input-output data is formulated and a ...

Abstract: As the interest in the seismic design of structures has increased considerably over the past few years, accurate predictions of the dynamic responses of soil and structural systems has become ...

Abstract: This paper investigates some problems related to the ill‐posedness of parameter identification problems which are commonly met with in structural and geotechnical engineering. Viewing the identification problem within a ...

Abstract: This paper presents the general form of the explicit equations of motion for mechanical systems. The systems may have holonomic and/or nonholonomic constraints, and the constraint forces may or ...
