Kinetic behaviours of carbon dioxide and carbon monoxide on carbon molecular sieve
Authors: Shirani Babak , Eic Mladen 
Published: July 2016

AbstractA carbon molecular sieve (CMS) is a carbonaceous material with a narrow pore size distribution, which can separate molecules based on their size, shape, and adsorption kinetic rate. In this study, a commercial CMS was used to measure the adsorption kinetics of carbon dioxide and carbon monoxide. The rate of adsorption was investigated by considering two main resistances, surface barrier and diffusion. The results showed that molecular parameters, such as difference in shape, size, and interactions of molecules, lead to different adsorption kinetics mechanisms. In the system investigated in this study, the adsorption kinetics of both CO2 and CO sorbates were controlled by combined diffusion and surface barrier mechanisms, in which the surface barrier was found to be the main resistance to gas molecule uptake. Even though this study confirmed surface resistance as a dominant transfer mechanism, the systematic use of the combined model in the analysis provided further insights in the mass transfer due to adsorption of CO2 and CO molecules in the CMS adsorbent.The rate constants were found to follow the Darken equation for both sorbates. The kinetic selectivity of CO2 over CO was calculated from the combined surface barrier/diffusion model parametric analysis. The results generally showed a greater selectivity to carbon dioxide over carbon monoxide, i.e. higher mass transfer rates.
Estimating the mean and its effects on Neyman smooth tests of normality for ARMA models
Authors: Duchesne Pierre , Lafaye De Micheaux Pierre , Tagne Tatsinkou Joseph 
Published: July 2016

AbstractGoodness‐of‐fit tests represent an important part of any model building strategy. In time series modelling, many test procedures concentrate on specifying the model structure. However it is also of interest to check distributional assumptions. In autoregressive moving‐average (ARMA) time series models, available results based on the smooth test paradigm assume that the mean of the process is known. However in practical applications, the mean is unknown and it needs to be estimated. Under general assumptions on the estimation procedures, the asymptotic distributions of the smooth test statistics based on estimation of all the parameters, including the mean, are derived. Surprisingly it is found that mean estimation has an impact on the asymptotic behaviours. This finding is in sharp contrast with portmanteau test procedures, where the degrees of freedom of the approximate distributions remain unchanged whether the mean is estimated or not. The test statistic relies on the order of the family, and a data‐driven choice of that parameter is discussed, giving a fully automatic testing procedure. Theoretical and empirical comparisons between the smooth test statistic assuming a known mean and the new test statistic are presented. Consistency is studied. In a simulation study, the effects of assuming incorrectly the mean being known are illustrated. An application using annual data on the productivity of potatoes (per acre) in Prince Edward Island for the time period 1957–2014 illustrates the procedure.
