Abstract:

Harmonic signals are often used for control of functional state of electronic devices. In this paper we show that the goal can be achieved via monitoring of the statistical behavior of harmonic signals propagating through the tested device. Malfunctions of the device lead to the changes in the statistical characteristics of the harmonic signals and thus are used for the monitoring of the technical state of the device. We consider statistical behavior of such signals at the variation of their phase, caused by malfunctions in electronic devices. Deviation of the mathematical expectation from its

Abstract:

We analyze the phase response of a system shaped as a ring of overdamped bistable and noisy oscillators coupled directionally. This device, which operates in the regime of stochastic resonance, may act as a short-term memory device. In the present work we show that in this regime the system presents partial phase synchronization with an average frequency equal to the external one. For lower/greater values of noise the system becomes more/less ordered, which is characterized by a statistical measure.

In this way, the proposed noise generator is a highly competitive alternative in cryptographic systems when the statistical behavior of the sequences is closer to the uniform statistical distribution. The proposed system uses the inverted tent chaotic map (IT-1D), which has the same statistical behavior as the T-1D map. T

Abstract:

In this paper, using gate structure engineering and modification of channel dopant profile, we propose a new double gate graphene nanoribbon field effect transistor (DG-GNRFET) mainly to suppress the band-to-band tunneling (BTBT) of carriers. In the new device, the intrinsic part of the channel is replaced by an intrinsic-lightly doped-intrinsic [Formula: see text] configuration in a way that only the intrinsic parts are covered by the gate contact. Transport characteristics of the device are investigated theoretically using the nonequilibrium Green’s function (NEGF) formalism. Numerical simul

Abstract:

Trapping of hot electron behavior by trap centers located in the buffer layer of a wurtzite phase GaN MESFET has been simulated using an ensemble Monte Carlo simulation. The simulated results show that trap centers are responsible for current collapse in GaN MESFET at low temperatures. These electrical traps degrade the performance of the device at low temperatures. On the other hand, at high temperatures, the electrical performances are improved due to electron emission from the trap centers. The simulated device geometries and doping are matched to the nominal parameters described for the ex

Abstract:

Uniaxial and bi-axial tests on tubular specimens are presented. The specimens consist of NiTi alloy exhibiting pseudoelastic behavior at room temperature. A novel device to measure and control axial and torsional strains within a well defined gage section of the specimen was developed. This device, based on inductive transducers, uses the same reference points for both twist and elongation measurements. The viscous and rate dependent behavior of binary, pseudoelastic NiTi is investigated. The main focus is on the decoupling of thermal and viscous effects on the transformation stress as the spe

Abstract:

Abstract The existence of bottlenecks often leads to the stagnation of pedestrian gatherings, which seriously affects the efficiency of traffic and reduces the flow of pedestrians. Some studies have shown that setting devices in front of bottlenecks can promote pedestrian evacuation under certain conditions. In this paper, the effect of setting diversion devices in front of the exit on pedestrian flow is studied. From our observation, these diversion devices can form a buffer zone before the exit and affect pedestrian behaviors. The evacuation times are found to decrease as the devices become

Abstract:

Background With the growing interest in mobile health (mHealth), behavioral medicine researchers are increasingly conducting intervention studies that use mobile technology (eg, to support healthy behavior change). Such studies’ scientific premises are often sound, yet there is a dearth of implementational data on which to base mHealth research methodologies. Notably, mHealth approaches must be designed to be acceptable to research participants to support meaningful engagement, but little empirical data about design factors influencing acceptability in such studies exist.

Abstract:

Membrane Bioreactors (MBR) combine traditional biological treatments such as Activated Sludge (AS) with a membrane-based filtration process to extract suspended and organic solids. MBR operation involves high shear rates near the membrane surface due to the high crossflow velocity, which complicates any simulation process from a hydrodynamic point of view. In this regard, the viscosity as a function of total suspended solids (TSS) plays an essential role in characterizing and modeling the behavior of activated sludge (AS). However, AS has an intransparency property that prevents experimental m

Abstract:

The effect of gate voltage on electronic transport properties in single C60 molecular device is investigated by a first-principles method based on density functional theory and nonequilibrium Green's function formalism. The calculated results show that the variation of the equilibrium conductance with gate voltage strongly corresponds with the variation of transmission eigenvalues and depends on the shift of molecular orbitals. The positive gate voltage can enhance the device's electronic transport, while negative gate voltage weaken it, which shows a gate-controlled molecular current switch.
