Breast cancer remains one of the deadliest diseases among women. Microcalcifications can be an early indicator of a breast cancer. Thus when they are present their detection during a screening test is very crucial. But due to their small size and low contrast in mammographies their detection is difficult. Therefore many computer aided diagnosis mathods have been developped to help and assist re...

fuzzy newton-cotes method for integration of fuzzy functions that was proposed by ahmady in [1]. in this paper we construct error estimate of fuzzy newton-cotes method such as fuzzy trapezoidal rule and fuzzy simpson rule by using taylor's series. the corresponding error terms are proven by two theorems. we prove that the fuzzy trapezoidal rule is accurate for fuzzy polynomial of degree one and...

The purpose of shaking tables is to replicate the desired motion to specimen, which needs to ensure not only the synchronization precision of two tables, but the tracking precision for the desired signal. Due to the nonlinearity of system and eccentric of load masses, both tracking and synchronous accuracy are poor. To solve this problem, this article proposes a novel hybrid controller combined...

Model-based control design is essential in the control of solar power plants. Dynamic linguistic equation (LE) models operate accurately in most operating conditions. Smooth transitions between submodels are based on fuzzy logic and fuzzy set systems are also used for special situations. The hybrid simulator has been tested with extensive process data, and the adaptive controller tuned with the...

Evaluation of evapotranspiration uncertainty is needed for proper decision-making in the fields of water resources and climatic predictions (Buttafuoco et al., 2010; Or and Hanks, 1992; Zhu et al., 2007). However, in spite of the recent progress in soil-water and climatic uncertainty quantification, using stochastic simulations, the estimates of potential (reference) evapotranspiration (Eo) and...

many of the so-called organizational strategies on which companies are dependent, are not endurable. these strategies may not be well structured and cannot stand the test of time. thus, making the right decision is extremely important for strategic planning. the proposed strategy formulation framework in this paper (fuzzy bsq) is a powerful management tool in strategic planning that integrates ...
