A New Look at the Trailing Zeroes of N !
نویسنده
چکیده
Let us denote by Zb(n) the number of trailing zeroes in the base b expansión of n!. In this paper we study with some detail the behavior of the function Zb. In particular, since Zb is non-decreasing, we will characterize the points where it increases and we will compute the amplitude of the jump in each of such points. In passing, we will study some asymptotic aspects and we will give families of integers that do not belong to the image of Zb. AMS 2000 Mathematics Subject Classification 11A25, 11A99

On the Base-b Expansion of the Number of Trailing Zeros of b!
Let Zb(n) denote the number of trailing zeroes in the base-b expansion of n!. In this paper we study the connection between the expression of θ(b) := limn→∞ Zb(n)/n in base b, and that of Zb(b ). In particular, if b is a prime power, we will show the equality between the k digits of Zb(b ) and the first k digits in the fractional part of θ(b). In the general case we will see that this equality ...
متن کاملSimulating Cooling Injection Effect of Trailing Edge of Gas Turbine Blade on Surface Mach Number Distribution of Blade
In this research, a gas turbine blade cascade was investigated. Flow analysis around the blade was conducted using RSM and RNG.K-ε turbulence modeling and it is simulated by Fluent software. The results were considered for the cases as Mach number loss at the trailing edge of blade caused by vortexes that were generated at the end of blade. Effect of cooling flow through the trailing edge on th...
متن کاملKinematic Synthesis of a Trailing Six-member Mechanism for Automotive Steering
Kinematic synthesis of a trailing six-member mechanism has been carried out to achieve five precision points of an automotive steering mechanism. The inner wheel can be rotated up to forty five degrees with fair accuracy. Results show that the divergent end behavior of Ackermann Steering Mechanism has been overcome by the present mechanism. The work is similar to earlier work by the present ...
متن کاملCaffeine effect on adenosine deaminase catalysis: A new look at the effect of caffeine on adenosine deaminase activity
The effect of physiological concentrations of caffeine (purified from Persian tea) on adenosine deaminase (ADA) activity at physiological and pathological concentrations of adenosine (as substrate) in 50 mM Tris-HCl buffer (pH 7.3) at 37°C was investigated, using UV-VIS spectroscopy. ADA exhibited a bi-phasic activity behavior and both phases showed positive cooperativities indicating adenosine...
