TL;DR: A new electrostatic probe method utilizing the triple probe is proposed in which no voltage or frequency sweep is required, allowing the instantaneous values of the electron temperature and the electron density to be determined within a short time.
Abstract: A new electrostatic probe method utilizing the triple probe is proposed in which no voltage or frequency sweep (or switching) is required. This feature enables us to determine the instantaneous values of the electron temperature (Te), as well as the electron density (ne), within a short time which is of the order of the intrinsic response time of the probe itself (⪝1μsec). Moreover, the system allows the direct display of the Te values as well as the semidirect display of the ne values on appropriate display units, thus permitting us to eliminate almost all procedures usually required for data processing. In view of the features mentioned, this system may be a useful diagnostic tool not only for stationary plasmas but also for rapidly varying time‐dependent plasmas of various types.This paper presents theoretical considerations for the instantaneous direct‐display system using a symmetrical triple probe. Discussions are also presented for the estimation of errors caused by the variation of ion saturation ...

TL;DR: This work studied the performance of the EZ-diffusion model in terms of parameter recovery and robustness against misspecification by using Monte Carlo simulations and the model was also applied to a real-world data set.
Abstract: The EZ-diffusion model for two-choice response time tasks takes mean response time, the variance of response time, and response accuracy as inputs. The model transforms these data via three simple equations to produce unique values for the quality of information, response conservativeness, and nondecision time. This transformation of observed data in terms of unobserved variables addresses the speed—accuracy trade-off and allows an unambiguous quantification of performance differences in two-choice response time tasks. The EZ-diffusion model can be applied to data-sparse situations to facilitate individual subject analysis. We studied the performance of the EZ-diffusion model in terms of parameter recovery and robustness against misspecification by using Monte Carlo simulations. The EZ model was also applied to a real-world data set.

TL;DR: In this paper, a control system for well stimulation equipment including a source of electrical power, injection fluid, fluid injection system, and a downhole electrical heater, electrically connected to the source of electricity, is described.
Abstract: A control system for well stimulation equipment including a source of electrical power, a source of injection fluid, a fluid injection system, and a downhole electrical heater, electrically connected to the source of electrical power includes one or more of temperature and pressure sensors both above and below grade for the purpose of monitoring process conditions. The sensor output is gathered in a computational unit and then manipulated for process control. The control system includes a response time which is defined as the time between a no flow condition at the heater and a shutting off of power, which response time is used to establish a temperature set point for the well stimulation equipment. A method of stimulating hydrocarbon recovery is also disclosed.

TL;DR: Measurements of the intrinsic response time of metal–graphene–metal photodetectors with monolayer graphene are presented using an optical correlation technique with ultrashort laser pulses to investigate the dependence of the response time on gate voltage and illumination laser power.
Abstract: Graphene-based photodetectors are promising new devices for high-speed optoelectronic applications. However, despite recent efforts it is not clear what determines the ultimate speed limit of these devices. Here, we present measurements of the intrinsic response time of metal–graphene–metal photodetectors with monolayer graphene using an optical correlation technique with ultrashort laser pulses. We obtain a response time of 2.1 ps that is mainly given by the short lifetime of the photogenerated carriers. This time translates into a bandwidth of ∼262 GHz. Moreover, we investigate the dependence of the response time on gate voltage and illumination laser power.
