investigating 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...
Intra-Industry Trade in a Loglinear Model∗
Within the framework of an n-commodity, n-factor, K-country loglinear model with identical Cobb–Douglas production coefficients and identical consumer-expenditure shares across countries, balanced trade, and a pattern of world endowments permitting positive outputs of all commodities in each country, it is shown that, given any mode of aggregating the n commodities into at most n − 1 industrial...

Reliability in the Rasch model
This paper deals with the reliability of composite measurement consisting of true-false items obeying the Rasch model. A definition of reliability in the Rasch model is proposed and the connection to the classical definition of reliability is shown. As a modification of the classical estimator Cronbach’s alpha, a new estimator logistic alpha is proposed. Finally, the properties of the new estim...
متن کاملA Dynamic Generalization of the Rasch Model
In the present paper a model for describing dynamic processes is constructed by combining the common Rasch model with the concept of structurally incomplete designs. This is accomplished by mapping each item on a collection of virtual items, one of which is assumed to be presented to the respondent dependent on the preceding responses and/or the feedback obtained. It is shown that, in the case ...
