The built up layer thickness in secondary deformation zone is one of the important parameters in metal cutting process. The built up layer (BUL) is formed in second deformation zone near the tool-chip interface in the back of the chip. This parameter influences the tool life and machined surface quality. This BUL should not be confused with the built up edge (BUE). The deformation of the BUL in...

This paper presents an integrated controller for autonomous articulated electric vehicle (AAEV) path tracking and rollover prevention. The AAEV is vulnerable to due the characteristics of frame steering (AFS) mechanism, which shows improved maneuverability agility but not front wheel steering. In addition, ratio between height track width high, so prone rolling over. Therefore, proposed was des...

compound-nucleus reactions provide the standard mechanism to populate states with high angularmomentum in neutron deficient nuclei. neutron-rich nuclei with mass aand induced fission. projectile fragmentation has proven to be an efficient method of populating nuclei farfrom the valley of stability. however, in the case of heavy nuclei this method is still limited to species withisomeric states....

Unlike the existing views that was introduced the existence of delay caused by the transmission of wide area measurement system data (WAMS) into the controllers input of the power oscilation damping (POD) by communication networks as a reason for poor performance of the POD controllers. This paper shows that the presence of time delay in the feedback loop may improve the performance of a POD co...

on 11th of august 2012 the region was surprisingly struck by a shallow mw 6.4 (usgs) earthquake with pure right-lateral strike-slip character only about 50 km north of the north-tabriz fault. an east-west striking surface rupture of about 20 km length was observed in the field by geological survey of iran. only 11 minutes later and about 6 km further nw a second shallow event with mw 6.2 occurr...

Offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. Thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. A safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. While the cost...

In this paper, symmetric water entry of twin wedges is investigated for deadrise angle of 30 degree. Three numerical simulation of a symmetric impact, considering rigid body dynamic equations of motion in two-phase flow is presented. The two-phase flow around the wedges is solved by Finite Element based on Finite Volume method (FEM-FVM) which is used in conjunction with Volume of Fluid (VOF) sc...

In this paper a new mechanism for providing an assured rate to a longlived TCP flow is proposed. The mechanism is called TCP rate controller (TRC) and operates as a traffic conditioner at the edge of a network. The TRC seeks to achieve the requested rate by imposing well directed drops and (artificial) delays on the flow’s packets. The choice of drop probability and delay is based on an analyti...

Optical microstructure arrays on metallic surfaces are drawing ever-increasing attention due to the increasing requirements in optical systems. Although vibration generators developed for generating microarrays with ultra-precision diamond cutting process, systematic research works its mechanical design, working performance simulation, and numerical simulation of has received less attention. In...
