A contribution to the knowledge of Scots pine (Pinus sylvestris L.) stem shape

open access: yesJournal of Forest Science, 2004
This is a study on the evaluation of stem shape in Scots pine. The experiments were carried out on 430 stems without bark, taken from 30 fully analysed sample trees that grew in 5 different locations in the Czech Republic. Generalized Procrustes analysis

An improved Fisher discriminant analysis algorithm based on Procrustes analysis for adaptive fault recognition

open access: yesMeasurement + Control, 2019
Aiming at the problem of continuous model updating for fault recognition in the time-varying process, a novel method called the Procrustes analysis–based Fisher discriminant analysis was proposed.

Using Generalized Procrustes Analysis for Evaluation of Sensory Characteristic Data of Lamb Meat

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2019
Generalized Procrustes Analysis (GPA) is a multivariate statistic method that is used at the evaluation of sensory analyses in the food industry. GPA provides benefit in terms of decreasing the difference between the panellists and bringing the data ...

Intrinsic Inference on the Mean Geodesic of Planar Shapes and Tree Discrimination by Leaf Growth [PDF]

open access: yes, 2010
For planar landmark based shapes, taking into account the non-Euclidean geometry of the shape space, a statistical test for a common mean first geodesic principal component (GPC) is devised.

Tools for quantitative form description : an evaluation of different software packages for semi-landmark analysis [PDF]

open access: yes, 2015
The challenging complexity of biological structures has led to the development of several methods for quantitative analyses of form. Bones are shaped by the interaction of historical (phylogenetic), structural, and functional constrains.

Comparing generalized procrustes analysis and statis [PDF]

open access: yesFood Quality and Preference, 2000
We consider a model for sensory profiling data including translation, rotation and scaling. We compare two methods to calculate an overall consensus from several data matrices: GPA and STATIS. These methods are briefly illustrated and explained under our model. A series of simulations to compare their performance has been carried out.

Human calcaneal variation relative to subsistence strategy, activity level, and footwear

open access: yesFrontiers in Earth Science, 2023
Lower limb cortical and trabecular bone varies with human behavior, leading to suggestions that activity level decreases have contributed to a more gracile skeleton.

On the Procrustean analogue of individual differences scaling (INDSCAL) [PDF]

open access: yes, 2013
In this paper, individual differences scaling (INDSCAL) is revisited, considering INDSCAL as being embedded within a hierarchy of individual difference scaling models.

A new diabatization scheme for direct quantum dynamics : procrustes diabatization [PDF]

open access: yes, 2020
We present a new scheme for diabatizing electronic potential energy surfaces, for use within the recently implemented direct-dynamics grid-based (DD-GB) class of computational nuclear quantum dynamics methods (DD-SM and DD-MCTDH), called Procrustes ...
