Abstract: The original PDF version of this article contained errors in equations 3, 4 and 5. In equation 3, the second term was written as ‘ ${{{\rm{acos}}}}({{{{\boldsymbol{u}}}}}_{i}^{T}\cdot \frac{{{{{\boldsymbol{c}}}}}_{i}(t)}{{{{{\boldsymbol{c}}}}}_{i}(t)\parallel })$ ’ but should have been written as ‘ ${{{\rm{acos}}}}({{{{\boldsymbol{u}}}}}_{i}^{T}\cdot \frac{{{{{\boldsymbol{c}}}}}_{i}(t)}{\Vert {{{{\boldsymbol{c}}}}}_{i}(t)\Vert })$ ’. In equation 4, the second and third terms were written as ‘ $({{{\rm{acos}}}}({{{{\boldsymbol{u}}}}}_{{{{\rm{PF}}}}}^{T}\cdot \frac{{{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)}{{{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)\parallel })-{{{\rm{acos}}}}({{{{\boldsymbol{u}}}}}_{{{{\rm{DF}}}}}^{T}\cdot \frac{{{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)}{{{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)\parallel }))$ ’ but should have been written as ‘ $({{{\rm{acos}}}}({{{{\boldsymbol{u}}}}}_{{{{\rm{PF}}}}}^{T}\cdot \frac{{{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)}{\Vert {{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)\Vert })-{{{\rm{acos}}}}({{{{\boldsymbol{u}}}}}_{{{{\rm{DF}}}}}^{T}\cdot \frac{{{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)}{\Vert {{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)\Vert }))$ ’. In equation 5, the second and third terms were written as ‘ $({{{\rm{acos}}}}({{{{\boldsymbol{u}}}}}_{{{{\rm{IN}}}}}^{T}\cdot \frac{{{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)}{{{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)\parallel })-{{{\rm{acos}}}}({{{{\boldsymbol{u}}}}}_{{{{\rm{EV}}}}}^{T}\cdot \frac{{{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)}{{{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)\parallel }))$ ’ but should have been written as ‘ $({{{\rm{acos}}}}({{{{\boldsymbol{u}}}}}_{{{{\rm{IN}}}}}^{T}\cdot \frac{{{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)}{\Vert {{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)\Vert })-{{{\rm{acos}}}}({{{{\boldsymbol{u}}}}}_{{{{\rm{EV}}}}}^{T}\cdot \frac{{{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)}{\Vert {{{{\boldsymbol{U}}}}}_{{{{\rm{S}}}}}(t)\Vert }))$ ’. These equations have now been corrected in the PDF. The equations in the HTML version were published correctly and remain unchanged.
