Uniaxial compressive strength (UCS) and internal friction coefficient (µ) are the most important strength parameters of rock. They could be determined either by laboratory tests or from empirical correlations. The laboratory analysis sometimes is not possible for many reasons. On the other hand, Due to changes in rock compositions and properties, none of the correlations could be applied as an ...

a reinforced concrete member in which the total span or shear span is especially small in relation to its depth is called a deep beam. in this study, a new approach based on the adaptive neural fuzzy inference system (anfis) is used to predict the shear strength of reinforced concrete (rc) deep beams. a constitutive relationship was obtained correlating the ultimate load with seven mechanical a...

the shear strength and shear energy per unit area, as well as the force and energy required for picking flowers, are important parameters in the design and development of harvesting mechanisms. in this study, shear strength and shear energy per unit area of saffron (crocus sativus l.) stems were determined at different bevel angles and shear velocities. the force and energy required for picking...

bond failure of brackets during orthodontic treatment is a common problem; which results in treatment interference, increased treatment time and prolonged clinical time for rebonding of failed brackets. the purpose of this study was to evaluate the effects of coca-cola and a non-alcoholic beer on the shear bond strength and adhesive remnant index (ari) of orthodontic metal brackets in vitro.eig...

original article   introduction: functional disability refers to conditions in which a person is not able to fulfill the daily chores and activities on his/her own or requires assistive devices to perform them. the objective of this study was to investigate the functional disability of the elderly in kerman, southeastern iran and its relationship with handgrip strength. method: this cross-secti...

The proliferation of wireless technologies along with the large volume of data available online are forcing us to re think existing data dissemination techniques for data over the Web and in particular for aggregate data In addition to scalability and response time data delivery to mobile clients with wireless Web connectivity must also consider energy consumption In this work we present a hybr...

In this paper, we introduce ordered clauses as defined a sequence of literals, and investigate the properties of generalizations for ordered clauses. Furthermore, we show that the subsumption problem for ordered clauses is NP-complete, as similar as the subsumption problem for ordinal clauses. Hence, the definition that a clause is a set of literals is inessential for the intractability of subs...

In this paper a novel algorithm is proposed that integrates the process of fuzzy hierarchy generation and rule discovery for automated discovery of Production Rules with Fuzzy Hierarchy (PRFH) in large databases. A concept of frequency matrix (Freq) introduced to summarize large database that helps in minimizing the number of database accesses, identification and removal of irrelevant attribute...
