In this paper, we develop a new algorithm for handling multiple patterns, which is based on average optimal shift-or algorithm. We have assumed that the pattern representation fits into a single computer word and length of each pattern is equal. We have adopted the concept of classes of characters for handling multiple patterns. We compare the performance of the proposed algorithm with the stan...

One way to create a random array is to map a random sequence into a two-dimensional pattern and an obvious choice is the use of shift-register sequences [10] or to use prime reciprocal sequences [11]-[14]. One dimensional binary random sequences are obtained as expansions of the prime reciprocal 1/p by [11],[12], a(i) = 2 mod p mod 2. Shift register (maximum length) sequences are obtained using...

Conditions are established for the existence of a scattering length and an effective range in the low-energy expansion of the S-wave phase-shift of a central potential in two and three dimensions. The behavior of the phase-shift as a function of the momentum is also derived for longer-range power-law potentials which do not fulfill these conditions. ar X iv :0 81 2. 40 54 v1 [ m at hph ] 2 1 D ...

We establish the relation between the exact energy of a two particle state in an asymmetric rectangular box with the elastic scattering phase shift of the two particle in the continuum. In particular, we obtain a formula which relates the elastic scattering length with the energy shift of the two particle in an asymmetric box. This can be viewed as a generalization of the corresponding formula ...

An improved approach to interferometry using sinusoidal phase shifting balances several harmonic components in the interference signal against each other. The resulting computationally efficient phase-estimation algorithms have low sensitivity to errors such as spurious intensity noise, vibration, and errors in the phase shift pattern. Specific example algorithms employing 8 and 12 camera frame...

We evaluate the isospin breaking corrections to the scattering amplitude πK → πK at threshold in the framework of chiral perturbation theory. This channel is of particular interest for the strong 2S− 2P energy level shift in pion–kaon bound states. While a prediction of this level shift is hampered by a large uncertainty in the isoscalar scattering length, we find only a moderate uncertainty of...

The effect of external fluctuations on the formation of spatial patterns is analyzed by means of a stochastic Swift-Hohenberg model with multiplicative space-correlated noise. Numerical simulations in two dimensions show a shift of the bifurcation point controlled by the intensity of the multiplicative noise. This shift takes place in the ordering direction ~i.e., produces patterns!, but its ma...

We propose a new additive binary stream cipher called Achterbahn. The keystream generator (KSG) consists of eight primitive binary nonlinear feedback shift registers (NLFSR’s). A binary N -stage feedback shift register is called primitive if it has a cycle of length 2N − 1 containing all binary nonzero N tuples. Each shift register has a configurable linear feedforward output function. The outp...

One of the fundamental properties of skeletal muscle, the force-length relationship (FLR), originally served as primary evidence for the sliding filament model of force generation (4). Past work has examined factors that may affect a muscle’s FLR, with evidence that the force depression of fatigued muscle correlates with a rightward shift in the muscle’s force-length (FL) behavior (3, 10). This...

Walker, J., and de la Mare, Gwynneth (1971). Brit. J. industr. Med., 28, 36-44. Absence from work in relation to length and distribution of shift hours. A long period on night shift or even permanent night work has sometimes been suggested for those on continuous shift work to allow circadian rhythms to adapt. As the weekly hours of work have been reduced there is some evidence that a permanent...
