Multiple circular–circular regression
Statistical Modelling, 2017In this article, we consider the circular–circular regression model using Möbius transformation. We first consider the model provided by Kato et al. (2008) for only one circular regressor and prove the identifiability of the model. After that, a methodology is discussed to reduce the prediction error of this model.

Circular‐circular regression model with a spike at zero
Statistics in Medicine, 2017With reference to a real data on cataract surgery, we discuss the problem of zero‐inflated circular‐circular regression when both covariate and response are circular random variables and a large proportion of the responses are zeros. The regression model is proposed, and the estimation procedure for the parameters is discussed.

Circularity is an assumption that was originally introduced for the definition of the probability distribution function of complex normal vectors. However, this concept can be extended in various ways for nonnormal vectors. The first purpose of the paper is to introduce and compare some possible definitions of circularity. From these definitions, it is

Circular patch antenna with circular and rectangular slots
2017 25th Signal Processing and Communications Applications Conference (SIU), 2017The microstrip patch antenna which is a type of antenna manufactured and measured to operate at the frequency of 9.93 GHz. The results of |S11| simulation and measurement are in good agreement. The designed antenna has one circular slot in the center and two rectangular slots with adding double wings to the right and left sides of the antenna ...

Circularity, evolution, systematics … and circularity
Journal of Evolutionary Biology, 1999Abstract Many have argued strongly that incorporation of evolutionary theory into systematics is dangerously circular, while others have maintained that such an integrated approach increases the accuracy of phylogenetic inference. Here, it is demonstrated that such blanket statements regarding exclusion or inclusion of evolutionary ...

Abstract Circular dichroism (optical activity) can only be observed for chiral molecules or in the case of molecule-ligand binding only if at least one of the interacting species is chiral. This is usually true in biochemistry particularly if a biological macromolecule such as a protein/peptide is involved.

Optics Letters, 2008
A very general beam solution of the paraxial wave equation in circular cylindrical coordinates is presented. We call such a field a circular beam (CiB). The complex amplitude of the CiB is described by either the Whittaker functions or the confluent hypergeometric functions and is characterized by three parameters that are complex in the most general ...

The problem of disentangling complex dynamic systems is addressed, especially with a view to identifying those variables that take part in the essential qualitative behaviour of systems. The author presents a series of reflections about the methods of formalisation together with the principles that govern the global operation of systems. In particular,

We define a finite-state machine called a circular automata (CA) which processes information in a queue; we show that any function computed (or any language recognized) by such a machine is computable (recognizable) by a Turing machine and vice versa. Space and time bounds are given for the needed simulations.
