A k-nacci sequence in a finite group is a sequence of group elements x0 , x1, x2 ,, xn , for<br />which, given an initial (seed) set 0 1 2 1 , , , ,j x x x x , each element is defined by<br />0 1 1<br />1 1<br />for ,<br />for .<br />n<br />n<br />n k n k n<br />xx x j n k<br />x<br />x x x n k<br /><br /> <br /> <br /> <br /><br /><br />In this paper, we examine the periods of the k-nacci sequences in Miller’s generalization of the polyhedral<br />groups 2,2 2;q , n,2 2;q , 2, n 2;q , 2,2 n;q , for any n 2 .

QCD FACTORIZATION IN HADRONIC B J/ ( ,K) DECAYS*
H.
MEHRBAN
M.
SAYAHI
Using QCD factorization for the hadronic matrix elements, we show that existing data, in<br />particular the branching ratios BR ( B →J/ψK) and BR ( B →J/ψπ), can be accounted for in this approach.<br />We analyze the decay B J /K( ) within the framework of QCD factorization. The calculation of the<br />relevant hard-scattering kernels for twist-2 and twist-3 is completed. We calculate this decay in a special scale<br />( mb ) and in two schemes for Wilson coefficients in NLO. We consider three functions for J / . The<br />twist-3 contribution involves the logarithmically divergent integral, we consider H 0 the canceling<br />divergent. The obtained results are in agreement with available experimental data.

In this paper, we find the number of sides of circuits in suborbital graph for the normalizer of<br />0 (m) in PSL(2,), where m will be of the form 2p2 , p is a prime and p 1 mod 4. In addition, we<br />give a number theoretical result which says that the prime divisors p of 2u2 2u 1 are of the form<br />p 1 mod 4.

A NOVEL NAVIGATION METHOD FOR PURSUING A MOVING TARGET

REZAII
The most current pursuit algorithms for moving targets which are presented so far in the literature<br />are Pure Pursuit and Pure Rendezvous navigations. Recently, one of the present authors has introduced a<br />geometric model for the Pure Pursuit navigation algorithm. Here, in this paper, we study a new algorithm for<br />the pursuit navigation problem which is a combination of both of the above algorithms. We study its<br />geometric properties, as well as the trajectories as time optimal paths. Finally, we compare this algorithm with<br />well-known algorithms in some real examples.

TWO-DIRECTION POLY-SCALE REFINEMENT EQUATIONS WITH NONNEGATIVE COEFFICIENTS
S.
YANG
J.
LIN
In this paper, we study L1 -solutions of the following two-direction poly-scale refinement equation<br />We prove that the vector space of all L1 -solutions of the above equation is at most one-dimensional and<br />consists of compactly supported functions of constant sign. We also show that any- L1 solution of the above<br />equation is either positive or negative on its support under a special assumption. With regard to the -<br />solutions of the equation, some simple sufficient conditions for the existence of nontrivial -solutions and<br />the nonexistence of such solutions are given.

J.
RAO
We develop a two phase sampling procedure to determine the sample size necessary to estimate<br />the population mean of a normally distributed random variable and show that the resulting estimator has preassigned variance and is unbiased under a regular condition. We present a necessary and sufficient condition under which the final sample mean is an unbiased estimator for the population mean.
