The paper presents an implementation of QoS Library Redirection (QLR) for DiffServ in Microsoft Windows systems. In QLR method, the legacy application obtains packet pre-marking ability without any modification of source codes. We have upgraded the FTP and vic applications by using QLR in our Microsoft Windows testing platform. Our experimental results show that this approach can use really eff...

We propose a new 3D barcode standard, Quick Layered Response (QLR) codes, and implemented encoding and decoding on Android devices. QLR codes are Quick Response (QR) codes superimposed in the RGB color space, and increase the capacity by a factor of 3. This advantage can be used to decrease the area needed to represent data by a factor of 3 or to increase the readable distance. QLR codes can be...

This paper considers inference on functionals of semi/nonparametric conditional moment restrictions with possibly nonsmooth generalized residuals, which include all of the (nonlinear) nonparametric instrumental variables (IV) as special cases. For these models it is often difficult to verify whether a functional is regular (i.e., root-n estimable) or irregular (i.e., slower than root-n estimabl...

This paper proposes a modified quasi-likelihood test of Markov regime switching models. Despite its popularity in economics and finance, there are few papers that develop tests for regime switching models. Recently, Cho and White (2007) derive the asymptotic distribution of the quasi-likelihood ratio (QLR) statistic of Markov regime switching models with a scalar parameter. The asymptotic distr...

We show that quasi-long-range (QLR) pair correlations that decay asymptotically with scaling r(-(d+1)) in d-dimensional Euclidean space R(d), trademarks of certain quantum systems and cosmological structures, are a universal signature of maximally random jammed (MRJ) hard-particle packings. We introduce a novel hyperuniformity descriptor in MRJ packings by studying local-volume-fraction fluctua...

We illustrate the need to use higher-order (specifically sixth-order) expansions in order to properly determine the asymptotic distribution of a standard artificial neural network test for neglected nonlinearity. The test statistic is a quasi-likelihood ratio (QLR) statistic designed to test whether the mean square prediction error improves by including an additional hidden unit with an activat...

Qualitative longitudinal research (QLR) has great potential for elucidating processes and change over time. Despite the growing interest in QLR, methodological practical challenges require further reflection. In this contribution, we reflect on two major issues interviewing adolescents QLR: panel maintenance changes set-up, including technique, content interviewer (dis)continuity. Based experie...

This study aims at investigating the challenges of conducting qualitative research (QLR) from Iranian ELT (English Language Teaching) Ph.D. students’ and ELT faculty members’ viewpoints in the Iranian higher education context. The participants of the study consisted of 100 Ph.D. students majoring in ELT and 50 ELT faculty members. The study followed a mixed-method appro...
