Super-steep retrograded (SSR) channels were compared to uniformly doped (UD) channels as devices are scaled down from 250 nm to the 50 nm technology node, according to the scheme targeted by the National Technology Roadmap for Semiconductors (1997). The comparison was done at the same gate length Lgate and the same off-state leakage current Io , where it was found that SSR profiles always have ...

The SHAAD model (Adaptable, Adaptive and Dynamic Hypermedia System) allows adapting the web content delivered to the user based on his/her preferences and characteristics, and the features and limitations of the device used to interact with the system. In this work we use CC/PP (Composite Capabilities/Preference Profiles) to describe the characteristics of devices and users’ preferences. Finall...

We present a theoretical description of the generation of ultra-short, high-energy pulses in an all-normal dispersion laser cavity with spectral filtering. A reduced variational model based upon the Haus master mode-locking equations with quintic saturation is shown to characterize the experimentally observed dynamics. Critical in driving the intracavity dynamics is the nontrivial phase profile...

Electrowetting on dielectric-coated electrodes involves two independently observable phenomena: (i) the well-known voltage dependence of the apparent contact angle and (ii) a central electromechanical force that can be exploited to move and manipulate small liquid volumes on a substrate. The electromechanical force does not depend upon field-mediated changes of the contact angle; it is operativ...

Air Traffic Management (ATM) has the objective to guarantee that the aircraft operators meet the scheduled time of departure and arrival to maintain optimal flight profiles with minimum constraints. This paper describes a solution of Air Holding Problem (AHP) of ATM in Brazil using Multiagent System to improve Reinforcement Learning in collaboration with the flight controllers to support the de...

Trade-offs in temperature control of fast-ramp RTP systems from an open-loop-input point of view are investigated, i.e., for a given desired temperature recipe a set of lamp command profiles is determined such that the resulting set of measured temperatures approaches the desired recipe as closely as possible. Exact tracking of fast-ramp recipes with rates such as 250 C/sec is usually not possi...

The ion saturation current and floating potential are measured with high temporal (1 μs) and spatial (2.5 mm) resolutions within the edge plasma of CASTOR tokamak by two poloidally spaced radial arrays of Langmuir probes. The radial electric field and the phase velocity of plasma fluctuations are determined. It is found that radial profiles of both of these quantities are strongly sheared in th...

We report on the creation of new lasing modes with spatially nonuniform profiles of optical gain in a one-dimensional random structure. It is demonstrated numerically that even without gain saturation and mode competition, the spatial nonuniformity of gain can cause dramatic and complicated changes. New lasing modes appear with frequencies between those of the lasing modes with uniform gain. We...

In this paper, we establish a mathematical framework that allows us to optimize the speed profile and select the optimal gears for heavy-duty vehicles. The key idea is to solve the analogous boundary value problem analytically for a simple scenario (linear damped system with quadratic elevation profile) and use this result to initialize a numerical continuation algorithm. Then the numerical alg...

Exact solution and variational approximation of eigenmodes in high gain FELs are presented. These eigenmodes specifi transverse profiles and exponential growth rates of the laser field before saturation. They are self-consistent-solutions of coupled Maxwell-Vlasov equations describing FEL interaction taking into account the effects due to energy spread, emittance and betatron oscillations of th...
