Abstract This paper presents the evolution of and influence that use a triangular grid has had on transformation layered structures during last two centuries. Historical facts, technological advances, economic social crises among other factors process change systems in architecture to make construction processes more efficient by reducing consumption materials qualified labor. Geometry structur...

The search for causes of the rising temperatures in some geographic areas during the twentieth century has directed interest toward the amount of atmospheric carbon dioxide (GOa). If the carbon dioxide added by the combustion of fossil fuels remains as a net increase, any temperature-changing effects of its presence as a minor constituent of the atmosphere should be cumulatively operative as th...

The topological approach to social choice was developed by Graciela Chichilnisky in the beginning of the 1980s. The main result in this area (known as the resolution of the topological social choice paradox) shows that a space of preferences admits of a continuous, anonymous, and unanimous aggregation rule for every number of individuals if and only if this space is contractible. Furthermore, c...

Using multisource data, this study focused on the process aspect of creativity at work. A modification of Amabile’s (1988) stage model of the creative process with the stages of problem identification, preparation, idea generation, and idea validation served as the basis for our study.We examined personal initiative and idea-related communication as two important factors for the creative proces...

Comparison of forest growth curves has led many to the conclusion that there is a similarity between forest stands growing in different conditions. Thus, in the beginning of the past century Alexander Turin, a wellknown forest scientist, made an important empirical generalization: “The normal pine stands with equal heights at a certain age had the same growth in the past and will have the same ...

T paper analyzes optimal selling strategies of a monopolist facing forward-looking patient unit-demand bidders in a sequential auction market. Such a seller faces a fundamental choice between two selling regimes: adaptive selling that involves learning about remaining demand from early prices, and commitment selling that forgoes such learning and makes all selling decisions in the beginning of ...

This paper describes new method for the synthesis of four-bar linkages for generating a required input-to-output motion. The synthesis method is based on the direct application of Chebyshev’s Alternation Theorem for the Equation of Freudenstein. By this approach the maximum structural error which corresponds to the best approximation can be estimated in advance. Two comparative examples are her...
