The 15 papers report new developments in the symmetrization of Jordan dialgebras, a prismatic classifying space, simple right conjugacy closed loops, multiplicative loops of Jha-Johnson semifields, and the orthogonality of approximate Latin squares and quasigroups.
Hua Ma, has concluded that, if vector space is having the following symmetry, orthogonality, homogeneity and completeness, it should have three dimensions having the energy obeys the law of conservation and the dynamics law is ruled by the covariance principle and hence we can define the cross product in the space.
The Coastal Act offers several advantages for measuring the effects of land-use regulations, including plausible exogeneity of the boundary location, which we confirm using historical data on boundary placement, and orthogonality of the boundary to other jurisdictional divisions.

The orthogonality of OAM modes is utilized to increase the capacity of communication in the form of optical fiber [8] and wireless communication [9-11].
In fact, we have the following orthogonality relation:
The 2nd and 3rd modes both begin to show a low-temperature interval area in the right direction of the pipeline, and the left parts of such 2nd and 3rd modes exhibit the characteristics of opposite changes with orthogonality. From the 4th mode, the increase in the number of static temperature variation interval area in the pipeline occurs.
To minimize the error, we should calculate the coefficients of the chosen functions, according to the method of orthogonality, for instance.
