Granular Pile Anchor (GPA) considers one of the solution foundation techniques, designed to mitigate the lifting of the sole resulting from expansive soils. This study work is to investigate the uplift movement response of (GPA) in expansive soil. The laboratory tests have been performed on an experimental. The effects of several parameters, such as length (L) of (GPA) and diameter (D), the thi...

because of fluctuation in leg tension, pitch motion is very effective fatigue and life safety of leg elements in tension leg structures (tlss). in this paper an exact solution for pitch vibration of a tls interacting with ocean wave is presented. the legs of tlp are considered as elastic springs. the flow is assumed to be irrotational and single-valued velocity potentials are defined. the effec...

In this paper, an interval Type-2 fuzzy logic based pitch angle controller is proposed for fixed speed wind energy system (WES) to maintain the aerodynamic power at its rated value. The pitch angle reference is generated by the proposed controller which can compensate the non-linear characteristics of the pitch angle to the wind speed. The presence of third dimension in the Type-2 fuzzy logic c...

The forty-nine Studies for player piano by Conlon Nancarrow are pervaded by the use of mathematical ratios, particularly ratios based on intervals found in the justly-tuned scale. Nancarrow found a remarkable variety of ways in which to deploy ratios in his Studies. The most obvious and pervasive use is in the establishment of different simultaneous tempos related by ratios as simple as 3:4 to ...

The design of a hybrid stepper motor for achieving a specific performance necessitates the choice of appropriate tooth geometry. In this paper, a detailed account of the results of twodimensional and three-dimensional finite-element (FE) analyses, conducted with different tooth width/tooth pitch ratios (t/X) and also with various tooth/slot shapes such as rectangular, trapezoidal, triangular, a...

In this Article dispersion characteristic of conventional optical waveguide with helical winding at core – cladding interface has been obtained. The model dispersion characteristics of optical waveguide with helical winding at core-cladding interface have been obtained for five different pitch angles. This paper includes dispersion characteristics of optical waveguide with helical winding, and ...

Abstract This study investigates agricultural wastes as potential fermentation substrates to provide a cheaper solution in rhamnolipid production by P. aeruginosa USM-AR2 while simultaneously attempting recycle waste. Rhamnolipid was estimated orcinol assay, oil spreading test (OST), and emulsification index (E 24 ). The used were waste cooking glycerine pitch. carried out shake flask culture u...

The continuous tube-rolling method has been widely used to manufacture high-quality seamless pipes and tubes. However, the analytical model for determining roll pitch diameter in three-roll retained mandrel rolling from first principles not yet presented, which has, thus, hindered development of control technology tube manufacturing. In this work, a new established force–equilibrium principles....
