In this study, fuzzy logic was implemented to formulate the fuzziness of layer boundaries for a two-layered clay soil. A field of two-layered clay with fuzzy boundaries between layers was generated, and then the bearing capacity of strip footing on this field was calculated by the assumption of plane-strain conditions. The Mohr-Coulomb failure criterion was used and bearing capacity calculation...

In this study, dynamic bearing capacity of adjacent shallow strip foundations located on sandy soil was examined using a numerical finite difference modeling, FLAC. The behavioral interference of shallow strip foundations under different conditions was investigated. The effect of soil strength parameters, geometric characteristics of shallow foundations and cyclic loads at different distance ra...

in this study. optimum allocation of heat transfer inventory for heat exchangers in a refrigeration system with specified power input or cooling capacity. and for a heat pump with specified heating capacity is investigated. the ratio of hot- to cold-end conductance unit cost ratio. g.was considered in the analysis as an additional variable of considerable importance to the designer summarized e...

In mobile communication systems, the received signal power varies due to fading, shadowing and path loss, resulting in the transmission performance degradation. Transmit antenna diversity is a promising technique to improve the transmission performance. For the downlink transmission, the outage probability in a service area can be improved by distributing the transmit antennas over the service ...

This paper formally defines the Ratio Modeling technique as set of steps enabling you to quickly perform low confidence capacity predictions, which are required when budgeting hardware, assessing technical risk, validating alternative technical architecture designs, sizing packaged applications, and predicting production system capacity requirements. This technique enables you to define the rel...

one of the import indices of food security evaluation is food import capacity index. ratio of total exports to food imports is often thought to be a measure of the capacity of a country to finance its food imports using revenues from exports of goods and services. this study investigates food import capacity effects on rural households food security by calculated ahfci (aggregate household food...
