The purpose of this descriptive-correlation study was to investigate effective factors on rural people’s non-participation of Mahabad’s dam catchment in Watershed Management Projects. The research instrument was structural questionnaire with close-ended questions, which its validity confirmed by panel of academic staff and reliability of questionnaire was confirmed. The target population of thi...

The paper begins with four propositions. 1), the effects of crosstalk coupling decrease with trace separation. 2), crosstalk coupled to a differential pair has meaning only for the differential component of the crosstalk on the differential pair, not the common mode component of the crosstalk. A differential component only exists because the outside trace is (perhaps only slightly) further away...

Reinforced Concrete (RC) deep beams are commonly used in structural design to transfer vertical loads when there is a vertical discontinuity in the load path. Due to their deep geometry, the force distribution within the RC deep beams is very different than the RC shallow beams. There are some strut and tie model (STM) already been developed for RC deep beams. However, most of these models are ...

Axial vibration effect of shell particles on dynamic stability of a cantilevered cylindrical shell under an axial follower force was addressed. In spite of free-ended shells, the reduced axial force under this effect cannot be derived analytically. Instead, an approximate method was proposed based on the fact that the static (and harmonic) axial deformation under an axial load in a free-ended b...

A recommendation system for an extended process of information retrieval in distributed information systems is proposed. This system is both a model of dynamic cognitive categorization processes and powerful real application useful for knowledge management. It utilizes an extension of fuzzy sets named evidence sets as the mathematical mechanisms to implement the categorization processes. It is ...
