We present the procedure for designing a high speed and low power all-optical analog to digital converter (AO-ADC), by integrating InGaAsP semiconductor optical amplifier (SOA) with InP based photonic crystal (PhC) drop filters. The self-phase modulation in the SOA can shift the frequency of the Gaussian input pulse. The two output PhC based drop filters are designed to appropriately code the f...

In this study, we propose to simulate the center of mass trajectory during walking using a tridimensional Extended Inverted Pendulum model. For the single support trajectory simulation, we consider a modified tridimensional inverted pendulum introducing the forward displacement of its pivot point as the center of pressure translation. The model introduces a representation of the double support ...

We study the properties of the 0 glueball at finite temperature using SU(3) quenched lattice QCD. We find a significant thermal effects near Tc. We perform the χ fit analyses adopting two Ansätze for the spectral function, i.e., the conventional narrow-peak Ansatz and an advanced Breit-Wigner Ansatz. The latter is an extension of the former, taking account of the appearance of the thermal width...

The spin-excitation continuum, expected to dominate the low-energy fluctuation spectrum in the Haldane spin chain around the Brillouin zone center, q = 0, is directly observed by inelastic magnetic neutron scattering in the S = 1 quasi-1D antiferromagnet CsNiCl3. We find that the single mode approximation fails, and that a finite energy width appears in the dynamic correlation function S(q,omeg...

In this paper, submerged vanes were placed at the upstream area of a bridge pier located at the 90 degree angle. Then, using the laboratory equipment, a study of flow pattern was conducted throughout the bend, specifically around the pier and submerged vanes. ADV velocimeter was incorporated in order to help measure 3D velocity components. Submerged vanes were installed at distances of 40 and 6...

We report generation of 48 fs pulses at a center wavelength of 2070 nm using a degenerate optical parametric oscillator (OPO) synchronously-pumped with a commercially available 36-MHz, femtosecond, mode-locked, Yb-doped fiber laser. The spectral bandwidth of the output is ~137 nm, corresponding to a theoretical, transform-limited pulse width of 33 fs. The threshold of the OPO is less than 10 mW...

We study the 0 glueball correlator constructed with SU(3) anisotropic quenched lattice QCD at various temperature taking into account the possible existence of the thermal width in the ground-state peak. For this purpose, we adopt the Breit-Wigner ansatz, analysing the lattice data obtained with 5,500–9,900 gauge configurations at each T . The results indicate the significant thermal width broa...

i ntroduction: due to the increase in le fort surgeries and its effect on nose widening, it seems necessary to use an alternative method without this effect. the present research examined the effect of alar release on interalar changes in le fort i osteotomy. m at erials and methods: the study population included patients admitted to bou-ali hospital in 2012-2013 undergoing le fort i osteotomy....

The thermal glueball is studied at finite temperature by using SU(3) anisotropic lattice QCD with βlat = 6.25, the renormalized anisotropy ξ ≡ as/at = 4 over the lattice of the size 20 × Nt with various Nt at the quenched level. While the narrow peak ansatz leads to the significant polemass reduction of about 300 MeV near the critical temperature Tc, Breit-Wigner ansatz which can take into acco...
