We report on how external cavity III-V/SiN hybrid lasers operate in regimes of ultra-damped relaxation oscillations or CW unstable dynamical (self-pulsing approaching turbulence) as a consequence mirror dispersion, non-zero linewidth enhancement factor, and four-wave mixing the gain medium. The impact dispersive bandwidth different effective lengths laser tolerance to optical feedback is also d...

In this paper, we propose an empirically based Monte Carlo bus-network (EMB) model as a test bed to simulate intervention strategies overcome the inefficiencies of bus bunching. The EMB is agent-based which utilizes positional and temporal data buses obtained from Global Positioning System (GPS) constitute (1) set empirical velocity distributions (2) exponential interarrival time passengers at ...

The pulsing inertial oscillation (PIO) model is a nonlinear, time-dependent, translating vortex solution of the inviscid, compressible fluid dynamic equations in the middle troposphere. The translation of this vortex during a pulse is strikingly similar to that of a supercell storm -a rotating thunderstorm that can generate tornadoes and hail. Two studies were performed to test the hypothesis t...

We present a set of models of AGB stars with initial mass larger than 5 M⊙ as obtained with the FRANEC code. It includes model of Z=0.02 and Z=0.001, with and without mass loss.

Pulsing Denial of Service (PDoS) is a type of DoS attack. Its attacking behavior is intermittent rather than constant, which helps it avoid being detected. In this paper, an adaptive detection method is proposed for source-end detection of PDoS attacks. It has three distinctive features: (i) its detection statistic is based on the discrepancy in the aggregated outbound and inbound packets; (ii)...

The mechanism of the formation for cocurrent downflow pulse flow was studied experimentally in a packed-bed of inert spheres of 3, 6, and 8 mm using an air-water flow. By measuring the flow distance until pulses are observed, the spatial growth rate of convective disturbances within the pulsing-flow regime were determined. Observations indicate that pulses form from trickling-flow as the result...

Effective methods of fluid transport vary across scale. A commonly used dimensionless number for quantifying the effective scale of fluid transport is the Reynolds number, Re, which gives the ratio of inertial to viscous forces. What may work well for one Re regime may not produce significant flows for another. These differences in scale have implications for many organisms, ranging from the me...

This paper addresses the important problem of detecting pulsing denial of service (PDoS) attacks which send a sequence of attack pulses to reduce TCP throughput. Unlike previous works which focused on a restricted form of attacks, we consider a very broad class of attacks. In particular, our attack model admits any attack interval between two adjacent pulses, whether deterministic or not. It al...
