Unified strength theory considering the influence of intermediate principal stress is widely used in geotechnical engineering, but singularities bring inconvenience to numerical calculation. A series equivalent area circle yield criteria based on unified are derived. The parameters new and Drucker-Prager discussed, flow vector coefficients given. very convenient for calculation can be served as...

Source/drain (S/D) series resistance components and device/process parameters contributing to series resistance are extensively analyzed using advanced model for future CMOS design and technology scaling into the nanometer regime. The total series resistance of a device is found to be very sensitive to the variations of the sidewall thickness, the doping concentration in the deep junction regio...

The scaling of transistors to sub-10 nm dimensions is strongly limited by their contact resistance (RC). Here we present a systematic study of scaling MoS2 devices and contacts with varying electrode metals and controlled deposition conditions, over a wide range of temperatures (80 to 500 K), carrier densities (10(12) to 10(13) cm(-2)), and contact dimensions (20 to 500 nm). We uncover that Au ...

The system shown in Figure 1 is a linear model of the Quanser SRV-02 DC motor with a static inertial load. In the model, • Rs is the resistance of the cable leading to the motor. Realistically, it should also include the output impedance of the amplifier driving the cable. Because the motor is a part of the process being controlled, the amplifier and cable together make up the actuator of the p...

Caffeine functions in the chemical defense against biotic attackers in a few plant species, including coffee and tea. Transgenic tobacco plants that endogenously produced caffeine by expressing three N-methyltransferases involved in the caffeine biosynthesis pathway exhibited a strong resistance to pathogens and herbivores. Here we report that transgenic Chrysanthemum, which produced an equival...

Theoretical limiting efficiencies have a critical role in determining technological viability and expectations for device prototypes, as evidenced by the photovoltaics community's focus on detailed balance. However, due to their multicomponent nature, photoelectrochemical devices do not have an equivalent analogue to detailed balance, and reported theoretical efficiency limits vary depending on...

Airborne capacitive micromachined ultrasonic transducers (CMUTs) have predominantly large input reactance with small series radiation resistance. To maximize the acoustic power at resonance we employ low cost LC matching networks between output impedance driving source and CMUT transducer. Conventional networks, including pi T-network topologies are employed to provide a high-Q match. An import...

In this study, we prepared activated carbon from coconut shell with a low activating time for (AC). The powder (< 100 µm) allows an effective pyrolysis process and activation (30 min) that reduces the cost of production. AC has characteristics micropore average size 1.9 nm surface area 460.50 m2/g. For supercapacitor electrode, electrodes have capacitance 50, 66, 67.5 F/g when 0.5 M, 1 2 M N...
