In this study, the effect of limited spatial resolution of hot wire anemometry (HWA) is investigated through analysis of the two dimensional energy spectra from direct numerical simulation (DNS) of turbulent channel flow at Reτ ≈ 934. Various spanwise filter lengths are applied to the streamwise velocity component in order to mimic the spatial resolution of the HWA experiments. The overall effe...

We study coherent electronic transport through a Coulomb blockaded superconducting Rashba wire in the co-tunneling regime between conductance resonances. By varying an external Zeeman field can be tuned into topological regime, where non-local Majorana zero modes is dominant mechanism. model by using scattering matrix formalism, and find that transmission amplitude has maximum as function of fi...

the hotelling's  control chart, is the most widely used multivariate procedure for monitoring  two or more related quality characteristics, but it’s power lacks the desired performance in detecting small to moderate shifts. recently, the variable sampling intervals (vsi) control scheme in which the length of successive sampling intervals is determined upon the preceding values has been pro...

-The problem of sensitivity in the wire antennas designed by genetic algorithm (GA) causes the results to be unfeasible to be constructed successfully. This problem is due to great variation of final objective (cost function) when the antenna has some physical variations. Moreover, these GA results are not reliable because of the fact that, usually cost functions of the well-done results show h...

Fab-less business model in semiconductor industry has led to serious concerns about trustworthy hardware. In untrusted foundries and manufacturing companies, submitted layout may be analyzed and reverse engineered to steal the information of a design or insert malicious Trojans. Understanding the netlist topology is the ultimate goal of the reverse engineering process. In this paper, we propose...

In a walking cycle design, maximizing the upright balance should be considered in addition to the kinematic constraints, energy consumption rate must be considered. The purpose of this study is to find the optimal step length obtained for each person according to the physical features. In this research, in order to minimize energy consumption rate by considering maximum balance two cost functio...

field ion microscopy (fim) and scanning tunneling microscopy (stm) have found a wide application in nanotechnology. these microscopes use a metallic nanotip for image acquisition. resolution of fim and stm images depends largely on the radius of nanotip apex; the smaller the radius the higher the resolution. in this research, for tungsten nanotip fabrication, electrochemical etching of tungsten...

Abstmct-VLSI communication networks are wire-limited. The cost of a network is not a function of the number of switches required, but rather a function of the wiring density required to construct the network. This paper analyzes communication networks of varying dimension under the assumption of constant wire bisection. Expressions for the latency, average case throughput, and hot-spot throughp...

This paper presents a parallel wire mechanism developed for measuring six degrees of freedom of a robot end!e}ector[ The mechanism consists of six parallel wire links[ The position and orientation of a robot are obtained from the wire lengths measured in the parallel wire mechanism[ The complex nonlinear equations of the forward kinematics are solved by using a NewtonÐRaphson method\ and a uniq...

this study analyses the concept of cost functions for semi-automated straddle carrier (sc), rubber tyred gantry (rtg) and automated rail mounted gantry (rmg) container yard operating cranes. it develops a generic cost based model for a pair-wise comparison, analysis and evaluation of economic efficiency and effectiveness of container yard equipment to be used for decision-making by terminal pla...
