Multi-level, multi-variate, non-stationary, random field modeling of engineering systems
… can often be represented considering models at multiple levels. Such levels can be defined by state variables (i.e., variables that describe the properties of the objective) or other quantities of interest (e.g., probability of failure) for the components in a system. For an engineering system, …

IMPROVING MULTI-VARIATE TIME SERIES FORECASTING WITH DYNAMIC MULTI-HEAD ATTENTION ADJACENCY MATRIX
… matrix based on related work called the Multi-variate Time-series Graph Neural Network(MTGNN). Instead of using a correlation-based learned adjacency matrix, the adjacency matrix and graph modules are replaced with a dynamically learned adjacency matrix with multi-attention. This …

Secondary school attendance policies in Indiana, attendance and withdrawal percentages, and other selected factors : a multi-variate analysis
The purpose of this study was to determine if any relationship exists among the factors of:(1) strictness of a secondary school's attendance policy,(2) its attendance percentages, and(3) its withdrawal/expulsion/push out percentages with respect to the school's:(4) student enrollment totals of …

Environmental and nature conservation : a facet study of concern for the quality of the natural environment
A multi-variate descriptive model of environmental and nature conservation attitudes and values is proposed and empirically supported. A mapping sentence is developed out of analysis of data from a series of Repertory Grid interviews addressing conservation employees' attitudes towards their …

Evaluation of a multi variated analysis for the selection of t-tbar multijet events in the current CMS implemented environment at LHC
In the present study we are using multi variate analysis techniques to discriminate signal from background in the fully hadronic decay channel of ttbar events. We give a brief introduction to the role of the Top quark in the standard model and a general description of the CMS Experiment at LHC. We …

Mining NHL Draft Data and A New Value Pick Chart
… from 1998 to 2008 were analysed using non-linear multi-variate model, with a modified weighted least squares, to predict a player's Time-On-Ice (TOI) for their first seven seasons. The results were analysed for positional advantage, then converted to value pick charts (used by teams when choosing …

Long-term vegetation change in the Succulent Karoo, South Africa following 67 years of rest from grazing
… 70 plots at this 75 ha site was assessed using multi variate ordination techniques. Changes in plant communities on termitaria sites were consistently greater than for adjacent off-termitaria sites and the north-facing slopes changed more than the south-facing slopes. There was a higher increase …
