In previous studies for nuclear reactor kinetics0, the author developed a mathematical formulation for special form of binomial expansion which introduced a new mathematical representation of nuclear reactor kinetics. Further research by the author introduced a generalization of the developed expansion which is named the Embedded Pascal Triangles (EPTs) expansion which has applications in different disciplines. It is the objective of this paper to extend the applications of the introduced expansion from neutronics to genomics applications. Hence, the paper explores the attempt to reduce the representation complexity of the DNA sequencing of genomes which then minimizes computer storage. Also the paper presents an attempt for providing a generating function of the DNA sequencing of genomes via the use of the EPTs expansion. The result of the attempt established a generating function which is capable of providing the number of A, T, C, and G nucleotides in the genome, along with a number representing all the possible sequences of those nucleotides, of which only one corresponds to the complete nucleotides sequence of the genome in concern. Four numbers which are called the four genomic numbers (n, k, k', k")  are used in the generating function to represent the number of nucleotides presented in the genome, and are used, as well, to represent the number of sequences (T) of those nucleotides, one of which corresponds to the complete sequence of the genome in consideration. Such T-number which is generated from the four genomic numbers, and the four genomic numbers themselves can be used for tagging of the genome in concern. Simple example was used to demonstrate the concept, and a tagging of the complete DNA sequence of the Hepatitis B Virus genome, using the tagger: T(n, k, k', k")   is presented in this paper.

RTC-method for the control of nuclear reactor power

In this paper, a new concept of the Reactivity Trace Curve (RTC) for reactor power control is presented. The concept is demonstrated for a reactor model with one group of delayed neutrons, where the reactivity trace curve is simply a closed form exponential solution of the RTC-differential equation identifier. An extended reactor model of multigroup (six groups) of delayed neutrons is discussed for power control using the RTC-method which is based on numerical solution of the governing equation for the RTC-differential equation identifier. In this numerical solution, an impeded analytical solution for the RTC-identifier in every sampling time step is used. Finally, the concept is applied to a more rigorous reactor model, namely; a model of multigroup of delayed neutrons with temperature feedback. The simulation studies for all of the above mentioned cases demonstrate the validity of the concept for reactor power control with absolute elimination of power shootings.
