The widely used weighted least squares (WLS) method, which is applied in the quantitative energy spectral processing for the pulsed neutron geochemical logging, suffers the absence of constraint condition of the solution variables and thus it is hardly to determine the elemental concentrations in a high precision and accuracy.
Freedom seems to have become less about the absence of constraint than about freedom from obligations to one another.
Like all natural systems, the magnet, in the absence of constraints, will try to maintain its magnetization in a direction such as to minimize stored energy; i.e., to make the demagnetizing field as small as possible.
The idea of freedom as the absence of constraints on the realization of given ends might be criticised as failing to capture this exercise concept of freedom, for the latter concept makes no reference to the absence of constraints.
Negative liberty Berlin initially defined as freedom from, that is, the absence of constraints on the agent imposed by other people.
