This column discusses the role of normality in regression, from simple linear regression, through multiple regression, to approaches such as principal component regression (PCR) and partial least squares (PLS). http://www.impublications.com/nir/abstract/N23_0119 This is the inaugural edition of a new column in NIR news which has been named (for want of a more serious title)“Mythbusters in Chemometrics”—precisely because mythbusting is its objective. The column will appear semi-regularly as our own themes develop and reactions to each article come in. Readers are encouraged to take up and contribute to what we expect to be a valuable scientific discussion. http://www.impublications.com/nir/abstract/N23_0116 The previous articles in this series have been mostly about Matlab and very little about spectroscopy. In this issue we will finally have a look at some spectroscopic data using the Octane data set from CAMO and the book by Kim Esbensen. http://www.impublications.com/nir/abstract/N23_0113 Plastic classification is an important field in which NIR HSI could be applied; correct identification and classification of plastics would enhance recycling efficiencies. but the existing literature on HSI-based methods is limited. HSI offers the important added benefit of being able to spatially map the location of various different plastic objects in a scene on the basis of their spectral signatures. In this study, the potential of NIR HSI combined with PLS-DA for the classification of different types of polymers is considered. http://www.impublications.com/nir/abstract/N23_0110 The Australian sugarcane industry is geographically situated in close proximity to environmentally sensitive and World Heritage listed areas of the Great Barrier Reef Marine Park and the Wet Tropics. As a result, the Australian sugar industry is subjected to a high level of scrutiny with respect to nutrient application rates and associated nutrient runoff. Legislation was passed at the beginning of 2010 the regulation of certain farming activities. In particular, the legislation was designed to minimise the impact of fertilisers and pesticides on the quality of run-off water entering the Great Barrier Reef lagoon by controlling maximum application rates on nearby land. This article outlines the development of near infrared spectroscopic methods for monitoring major nutrient elements in sugar mill byproducts. http://www.impublications.com/nir/abstract/N23_0108 This article empiracly explores the optimal conditions of fruit orientation, light source power and sample holder for NIR transmission measurements for the tropical fruit mangosteen. http://www.impublications.com/nir/abstract/N23_0106 The interview this issue is with the recently announced winner of the 2011 Büchi Young Scientist NIR Award, Manel Alcalà i Bernàrdez of the Applied Chemometrics research group, Departament de Química, Universitat Autònoma de Barcelona, Spain. http://www.impublications.com/nir/abstract/N23_0104 Meeting report on the The 27th NIR Forum organised by the Japan Council for Near Infrared Spectroscopy (JCNIRS) which was held from 9 to 11 November 2011 at the The Tsukuba Center, Tsukuba, Japan http://www.impublications.com/nir/abstract/N23_0103 News, new product information and forthcoming events
