Strengthening of flat slab-column connections to resist imposed lateral drifts is often required for older reinforced concrete structures in which the slabs were typically designed gravity load only or have been less stringent requirements. The complex stress state around columns means that strong experimental evidence repair and strengthening techniques be adopted with confidence practice. Alt...

The resonant frequency and sensitivity of an atomic force microscope (AFM) cantilever with assembled cantilever probe (ACP) have been analyzed and a closed-form expression for the sensitivity of vibration modes has been obtained. The proposed ACP comprises an inclined cantilever and extension, and a tip located at the free end of the extension, which makes the AFM capable of topography at sidew...

This paper presents a 4th order CLCL resonant converter which is suitable for constant current power supply applications. This converter is designed with Immittance characteristic with two inductors and two capacitors in resonant network. A detailed analysis and design process of a 200w converter as a constant current supply have been provided and simulation results are verified with results of...

Finite element simulation of the column bending test (CBT) is carried out using shell elements with anisotropic viscoelastic section properties. The CBT an experimental method for evaluating behavior thin-ply high strain composites (TP-HSC), to support development deployable composite booms space structures. A linear formulation derived and implemented two solution techniques: quasi-elastic (QE...

heavy metals due to their non biodegradability properties and can accumulate in living tissues, thus becoming concentrated throughout the food chain and can be readily absorbed into the human body. among them manganese was examined in this study as a pollutant. the aim of this study is the manganese removal from aqueous solution using a windy sand fixed bed column of sistan plain. flow rate, in...

Spontaneous combustion of coal is an important problem in mining and storage, in terms of both safety and economics. This is because coal reacts with oxygen in the air and an exothermic reaction occurs, even in ambient conditions. The heat of the reaction accumulates and the reaction becomes progressively faster and thermal runaway may take place to the point of ignition. A detailed computer mo...
