A preconditioned multigrid for simulation of atmospheric flow and wind turbine wakes
(Elsevier, 2015-11-20)
This paper demonstrates a low Mach number preconditioning formulation for high Reynolds number, low Mach number atmospheric flows. The preconditioning is implemented together with multigrid approach into a multistage solver ...
Understanding selectivity on Germanium/SiO2 chemical mechanical planarization through design of experiments
(Cambridge University Press, 2015)
The continuous trend of achieving more complex microelectronics with smaller nodes yet larger wafer sizes in microelectronics manufacturing lead to aggressive development requirements for chemical mechanical planarization ...
Near-field thermal radiation transfer by mesoporous metamaterials
(The Optical Society, 2015-09-21)
In this work, we investigate the impact of nano-scale pores within structured metamaterials on spectral near-field radiative transfer. We use Finite Difference Time Domain Method (FDTD) and consider uniform and corrugated ...
Calibration of 2D ultrasound in 3D space for robotic biopsies
(IEEE, 2015)
Freehand Ultrasound technique is widely used in intraoperative biopsy procedures for detecting the volumes of interest. Freehand ultrasound probe is faster and flexible with 6 degrees of freedom. Thats why the imaging ...
A computational and experimental investigation of synthetic jets for cooling of electronics
(The American Society of Mechanical Engineers, 2015-06-01)
Seamless advancements in electronics industry resulted in high performance computing. These innovations lead to smaller electronics systems with higher heat fluxes than ever. However, shrinking nature of real estate for ...
Existence and stability of traveling waves for a class of nonlocal nonlinear equations
(Elsevier, 2015-05-01)
In this article we are concerned with the existence and orbital stability of traveling wave solutions of a general class of nonlocal wave equations: utt−Luxx=B(±|u|p−1u)xx, p>1. The main characteristic of this class of ...
Fatigue behavior of friction stir welded joints of pure copper with ultra-fine grains
(Elsevier, 2015)
In order to determine the long term durability of friction stir welded joints with ultra-fine grained microstructure, investigation of the mechanical response with specific emphasis on fatigue behaviour is critical. In ...
A design and optimization method for matching the torque of the wind turbines
(AIP Publishing, 2015)
An aerodynamic shape optimization method for a horizontal axis wind turbine is developed and verified through experimentation with a laboratory-scale wind turbine. Our method is based on matching the rotor's and the coupled ...
Controlling germanium CMP selectivity through slurry mediation by surface active agents
(The Electrochemical Society, 2015-08-10)
New developments and device performance requirements in microelectronics industry add to the challenges in chemical mechanical planarization (CMP) process. One of the recently introduced materials to semiconductor manufacturing ...
Sound performance investigation of composite materials for the soundbox of a membrane musical instrument
(International Institute of Acoustics and Vibrations, 2015)
The materials used in the manufacture of musical instruments with wooden sound box is obtained from trees in general. This fact creates difficulties due to problems with limited environmental resources. In addition, such ...
