The primary contribution of the presented work is the development and implementation of the Integrated Tracking System algorithm which was implemented in two levels.
The primary contribution of the presented work is the design and implementation of a dynamic user-viewpoint tracking scheme in which mobile users' spatial context is defined not only by their position (i.e., location), but also by their three-dimensional head orientation (i.e., line of sight).
Based on the above discussion, the primary contributions of the present work are as follows: 1) A M-GEOPF model incorporating PtG units is formulated based on precise nonlinear power and gas flow models, where the dynamical characteristics of the gas network are specifically modeled.
Then we introduce the main contribution of the present paper.
Their discovery is the principal contribution of the present work.
This constitutes the main contribution of the present work.
This is the primary contribution of the current paper.
One primary contribution of the review at hand is the consideration of various research fields.
