Panel Cointegration; Asymptotic and Finite Sample Properties of Pooled Time Series Tests, With an Application to the PPP Hypothesis; New Results. Working paper

by Peter Pedroni , 1997
"... We examine properties of residual-based tests for the null of no cointegration for dynamic panels in which both the short-run dynamics and the long-run slope coefficients are permitted to be heterogeneous across individual members of the panel+ The tests also allow for individual heterogeneous fixed ..."

An Automatic Grading System for Panels Surfaces Using

by Cristhian Aguilera, Mario Ramos, Gabriel Roa - Artificial Vision, International Journal of Computers, Communications and Control , 2006
"... Abstract: This work describes an automatic grading system using artificial vision to improve the quality of wood panels surfaces. The objective is to control stains on the surface. Artificial Vision techniques like Thresholding and Transformed Watershed methods are applied. Defects quantitative meas ..."

to dimming at the Earth's surface with important implications for the hydrological cycle, and the deposition of black carbon darkens snow and ice surfaces, which can contribute to melting, in particular of Arctic sea ice. Black carbon (BC) is an important part of the combustion product commonly referred

Purchasing power parity tests in cointegrated panels

by Peter Pedroni - The Review of Economics and Statistics , 2001
"... Abstract—This paper employs recently developed techniques for testing hypotheses in cointegrated panels to test the strong version of purchasing power parity for a panel of post Bretton Woods data. We compare results using fully modi � ed and dynamic OLS approaches, and strongly reject the hypothesi ..."

Sound insulation of application for composite wood panel

by Wen Chuan , Chou , ; Chen , Yu Chen , ; Rong , Ping Lai , ; Philip Sun
"... ABSTRACT Glued laminated timber, also called Glulam, was applied on various building components, space products, and decoration materials. The extensively application of Glulam was attributed to its feature with durable, ease processing, attractive appearance, and sustainability. According to the f ..."
Abstract - Add to MetaCart
insulation of composite wood panel was still focused on the surface density but no more controlling factors of sound insulation for quantitative analysis. By the new technique of composite wood panel, the uncertain of quality analysis would cost wasting from repeatedly replacement during construction just

Parametric Analysis on Delamination in Drilling of Wood Composite Panels

by T. N. Valarmathi, K. Palanikumar, S. Sekar
"... Composites are widely used in all the fields because of its favorable properties over conventional materials. Medium Density Fiberboard (MDF) is an extensively used wood composite in furniture industries. Drilling is the most commonly used machining process in the assembly. The surface quality of th ..."

parameters in a systematic approach on delamination in drilling of prelaminated MDF wood panels with High Speed Steel (HSS) twist drills of different diameters. The drilling experiments were planned and performed using Taguchi design. Response Surface Methodology (RSM) based mathematical model is developed

Wetting pattern of sheathing panels in wood stud walls

by Evelien Pegge, Dominique Derome, Anik Teasdale-st-hilaire
"... Water infiltration in wood frame walls leads to different water transport phenomena: water runoff and spreading of water on the sheathing, water infiltration into the insulation, water flow on the bottom plate and into the bottom plate-sheathing joint, water uptake by sheathing, stud and bottom plat ..."

Nominal exchange rates and monetary fundamentals: Evidence from a small post-Bretton woods panel

by Nelson C. Mark, Donggyu Sul - Journal of International Economics , 2001
"... We study the long-run relationship between nominal exchange rates and monetary fundamentals in a quarterly panel of 18 countries extending from 1973.1 to 1997.1. Our analysis is centered on two issues. First, we test whether exchange rates are cointegrated with long-run determinants predicted by eco ..."

Some Properties of Composite Panels Made from Wood Flour and Recycled Polyethylene

by Turgay Ozdemir, Fatih Mengeloglu , 2008
"... Abstract: This study investigated the effect of board type (unmodified vs. MAPE modified) on the surface quality and thickness swelling-water absorption properties of recycled high density polyethylene (HDPE) based wood plastic composites. Additionally, two commercially available coatings (cellulosi ..."
