a Simplified Model of Distributed Parameter Systems
A generalized simplified model for describing the dynamic behavior of distributed parameter systems is proposed. The various specific characteristics of gain and phase angle of distributed parameter systems are investigated from frequency response formulation and complex plane representation of the proposed simplified model. The complex plane investigation renders some important inequality cons...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
A psychosocial kinship model for family therapy.
Family therapy has traditionally centered on the nuclear family and thus has been typically oriented toward urban white middle-class families. A variety of modifications in therapeutic technique has evolved for work with the many modern families whose structure consists of a functional psychosocial family kinship. The authors have developed a formal theoretical framework and model for family th...
متن کاملA Structural Model for Kinship Studies
Several mathematical models have been proposed for kinship studies. We propose an alternate structural model designed to be so simple logically and intuitively that it can be understood and used by anyone, with a minimum of complication. It is called a P-system, which is short for parental system. The P-system incorporates the best features of each of the previous models of kinship: a single re...
متن کاملA Simplified Model
A simple set of equations for bubbly flow through a vertical tube is rigorously derived by means of a scale analysis from the realistic equations posed by Pauchon. It is shown that under steady flow conditions the void fraction will relax from its value at the inlet towards an asymptotic value within only a short distance of the inlet. The relationship between the inlet void fraction and the im...
