Various implementations are known for the efficient implementation of adders. As opposed to traditional optimization techniques a statistical approach using early termination detection is used in this article to obtain efficient implementations for large operands. The completion detection logic is described and the efficiency of the approach is shown and analyzed analytically and through comput...

Allochthonous masses are common structures in Zagros fold-thrust belt. They are generally considered as collapse structures formed by the influence of gravity and in rock units with competency contrast. However, large allochthonous masses mapped in Dowgonbadan area in Dezful Embayment near the Mountain Front Fault (MFF) of Zagros show characteristics different from the belt common collapse stru...

The O(a) improved Wilson quark action on the anisotropic lattice is investigated. We carry out numerical simulations in the quenched approximation at three values of lattice spacing (a σ = 1–2 GeV) with the anisotropy ξ = aσ/aτ = 4, where aσ and aτ are the spatial and the temporal lattice spacings, respectively. Using the dispersion relation of mesons, the bare anisotropy γF in the quark action...

Adders are some of the most critical data path circuits requiring considerable design effort in order to squeeze out as much performance gain as possible. Various adder structures can be used to execute addition such as serial and parallel structures and most of researches have done research on the design of high-speed, low-area, or lowpower adders. Adders like ripple carry adder, carry select ...

T HE literature on anesthetic concerns and perioperative care of patients with mediastinal masses has focused almost exclusively on anterior mediastinal masses. Posterior mediastinal masses traditionally have been suggested to carry a low risk of anesthetic implications. We present the case of a patient with a posterior mediastinal mass who experienced hemodynamic and respiratory decompensation...

For organisms with complex life histories, carry-over effects (COEs) can manifest between life stages, when conditions experienced by one stage influence the next, as well as trans-generationally, when the parental environment affects offspring. Here we used multiple global change-associated stressors to examine both forms of COE simultaneously in an intertidal limpet with mixed development (i....

The FFT is commonly used essential tool in digital signal processing applications .The adders used in Conventional Fast Fourier transform(FFT) are no longer appropriate for the reason that of its degraded rapidity concert. There are many dissimilar kinds of fast adders such as Carry Select Adder, Carry Save Adder and Carry Look Ahead Adder have been used for Fast Fourier Transform. However, the...
