In the presence of selection bias the traditional estimators for pseudo panel data models are inconsistent. This paper discusses a method to achieve consistency in static linear pseudo panels in the presence of selection bias and a testing procedure for sample selection bias. The authors’ approach uses a bias correction term proportional to the inverse Mills ratio with argument equal to the “no...

We present a 91 MHz surface acoustic wave resonator with integrated microfluidics that includes a flow focus, an expansion region, and a binning region in order to manipulate particle trajectories. We demonstrate the ability to change the position of the acoustic nodes by varying the electronic phase of one of the transducers relative to the other in a pseudo-static manner. The measurements wer...

On early BSD systems, network interfaces were static objects created at kernel compile time. Today the situation has changed dramatically. PC Card, USB, and other removable buses allow hardware interfaces to arrive and depart at run time. Pseudo-device cloning also allows pseudo-devices to be created dynamically. Additionally, in FreeBSD and Dragonfly, interfaces can be renamed by the administr...

The wave type field equation θ = λθ, where θ is a coframe field on a space-time, was recently proposed to describe the gravity field. This equation has a unique static, spherical-symmetric, asymptotically-flat solution, which leads to the viable Yilmaz-Rosen metric. We show that the wave type field equation is satisfied by the pseudo-conformal frame if the conformal factor is determined by a sc...

We describe a practical e-voting protocol which guarantees e-voting protocol requirements: eligibility, privacy, accuracy, fairness, receipt-freeness, uncoercibility, robustness and verifiability. Unlike existing blind signature based protocols, in which the authority blindly signs ballot or part of ballot, the authority in our protocol blindly signs voter’s pseudo identity. Hereafter, voter be...

Automated programming assessment is a computer aided approach in checking and grading students programming exercises, without the hassle of doing it manually. This is an attempt to conduct programming exercise assessment using one of the static analysis approaches; a non-structural similarity analysis by using the pseudo-code comparison. The application will generate the pseudo-code for the stu...

Abstract This paper addresses a simple energy-based overset finite element method (EbO-FEM) to solve pseudo-static deformation problems consisting of overlapped meshes based on the domain composition (DCM). scheme is non-iterative equation-based for enforcing continuity displacement field. Hence, consumes possible minimal computational costs with non-conforming overlapping meshes. The system’s ...

Failure of the quay walls due to earthquakes results in severe economic loss. Because of hazards threatening such inexpensive nodes of national and international transportation networks, seismic design of quay walls is still an evolving topic in marine structural engineering. This study investigates the sensitivity of the gravity-type quay wall stability respect to uncertain soil and seismic pr...

Response modification factor (R factor) is one of the seismic design parameters to be considered in evaluating the performance of buildings during strong motions. This paper has tried to evaluate the response modification factor of concrete coupled shear wall structures with various length/depth ratios of spandrel beams. The effect of diagonal reinforcement of spandrel beam was also evaluated o...
