Effect of Insert Angles on Cutting Tool Geometry [PDF]

open access: yesЖурнал інженерних наук, 2020
An analysis of publications has shown that mechanically clamped indexable inserts are predominantly used in modern tool manufacturing. Each insert has its shape and geometry in the tool coordinate system. The static system’s required geometry is achieved

Solving Einstein's Equations With Dual Coordinate Frames [PDF]

open access: yes, 2006
A method is introduced for solving Einstein's equations using two distinct coordinate systems. The coordinate basis vectors associated with one system are used to project out components of the metric and other fields, in analogy with the way fields are ...

Degree of Freedom of Gene Expression in Saccharomyces cerevisiae

open access: yesMicrobiology Spectrum, 2022
The complexity of genome-wide gene expression has not yet been adequately addressed due to a lack of comprehensive statistical analyses. In the present study, we introduce degree of freedom (DOF) as a summary statistic for evaluating gene expression ...
