In this letter, a new two-parametric pulse that outperforms state-of-the-art pulses with the best performance in terms of BER is proposed, which studied frequency and time domain characteristics. Specifically, based on inverse-hyperbolic functions acsch asech are used for first an ISI-free pulse, its design depends only roll-off factor timing jitter parameter (i.e., design). Finally, proposed s...

We demonstrate a femtosecond optical parametric oscillator based on two nonlinear crystals synchronously pumped by a single ultrafast laser for efficient intracavity signal amplification and output power enhancement. By deploying two identical MgO:PPLN crystals in a single standing-wave cavity, and two pump pulse trains of similar average power from the same Kerr-lens-mode-locked Ti:sapphire la...

In this paper we propose solutions to the FMTV challenge of a distributed video processing system using the formalism of Parametric Timed Automata (PTA). The first challenge is harder because of the very large number of states to be analysed, so we only provide upper bounds. The second challenge consists of a real-time scheduling problem for which we provide exact solutions by using a schedulin...

This paper demonstrates a method to remove the gain ripple profile specifically for a two-segment fiber optical parametric amplifier arising from the dispersion differences between the fiber gain medium and the standard single mode fiber attached to the optical components. This is achieved by using a simple design that incorporates a gain smoothening filter at the mid-stage of the amplifier. Th...

We show that for all integers m and n there are no non-trivial solutions of Thue equation x − 2mnxy + 2 ( m − n + 1 ) xy + 2mnxy + y = 1, satisfying the additional condition gcd(xy,mn) = 1.

The parametric bootstrap tests and the asymptotic or approximate tests for detecting difference of two Poisson means are compared. The test statistics used are the Wald statistics with and without log-transformation, the Cox F statistic and the likelihood ratio statistic. It is found that the type I error rate of an asymptotic/approximate test may deviate too much from the nominal significance ...

Aims: This study was designed to investigate the antimicrobial effect of camel and sheep urine to Staph aureus (S.aureus), Escherichia coli (E. coli). Salmonella SP, Pseudomonas aeruginosa (ps. Aeruginosa) and Enterobacter cloacae (E. cloacae). Study Design: a total of 100 samples of urine (60 from camels and 40 from sheep) collected fromdifferent localities in Sudan including:Tampool, Elobied ...
