limit to the tension reinforcement ratio ( ρ) in flexural high strength reinforced concrete (hsrc) members is based on the requirement that tension failure as sufficient rotation capacity are ensured at ultimate limit state. however, the provisions for the total amount of longitudinal reinforcement ratio ( ρ and ρ’) are not associated with any rational derivation. in this paper, a quantitative ...

In this paper, we consider the AWGN channel with a power constraint called the (σ, ρ)-power constraint, which is motivated by energy harvesting communication systems. Given a codeword, the constraint imposes a limit of σ+kρ on the total power of any k ≥ 1 consecutive transmitted symbols. Such a channel has infinite memory and evaluating its exact capacity is a difficult task. Consequently, we e...

A preliminary analysis of exclusive b → uℓν decays to the final states π ∓ ℓ ± ν, π 0 ℓ ± ν, ρ ∓ ℓ ± ν, ρ 0 ℓ ± ν and ωℓ ± ν based on 2.2 × 10 6 B ¯ B decays collected at CLEO is presented. We have measured the first exclusive b → uℓν branching fraction B(B 0 → π − ℓ + ν) =), with the ISGW (WSB) model used for efficiency determination. A 90% C.L. upper limit on B(B 0 → ρ − ℓ + ν) similar to the...

A resonance X(3872), first observed in the decays B → KX, has been seen to decay to J/ψππ. The ππ mass spectrum peaks near its kinematic upper limit, prompting speculation that the dipion system may be in a ρ. The decay X(3872) → J/ψω also has been observed. The reaction γγ → J/ψππ has been studied. Consequently, angular distributions in decays of J/ψ(ρ, ω) states near threshold are of interest...

We establish sufficient criteria for the existence of a limit cycle in the Liénard system x[over ̇]=y-ɛF(x),y[over ̇]=-x, where F(x) is odd. In their simplest form the criteria lead to the result that, for all finite nonzero ɛ, the amplitude of the limit cycle is less than ρ and 0≤a≤ρ≤u, where F(a)=0 and ∫(0)(u)F(x)dx=0. We take the van der Pol oscillator as a specific example and establish that ...

We use the experimental limit on the interference of M1 and E2 multipoles in the γ-decay of 57 Fe to bound the time-reversal-violating parity-conserving ρN N vertex. Our approach is a large-basis shell-model calculation of the interference. We find an upper limit on the parameter ¯ g ρ , the relative strength of the T-violating ρN N vertex, of close to 10 −2 , a value similar to the best limits...
