Current efficiency in the lithium-water battery
Journal of Power Sources, 1977Abstract Under well-controlled conditions, the exceptional energy of the LiH 2 O reaction can be harnessed electrochemically with high Faradaic efficiency. The most important adjustable control parameters are electrolyte flow rate, electrolyte concentration, temperature and anode—cathode contact pressure.

Is Current Surgical Training Efficient? A National Survey
Journal of Surgical Education, 2014Evaluation of surgical training in Denmark is competency based with no requirement for a specific number of procedures. This may affect monitoring of surgical progress adversely and cause an underestimation of the time needed to acquire surgical competencies. We investigated the number of common surgical procedures performed by trainees.

Current Efficiency and Alumina Concentration
2016A reaction model for the back reaction between carbon dioxide and aluminium is presented. By introducing in the model available data for metal- and gas-solubilities, gas bubble sizes, and the physical-chemical data for the cell electrolyte, we have calculated how the current efficiency should vary with the concentration of dissolved alumina in the ...

Area efficient current steering DAC using current tuning
Asia-Pacific Conference on Circuits and Systems, 2003A 10 bit segmented (5+5 bit) high speed current steering DAC is presented in this paper. Devices with small area are used to reduce the total area without affecting linearity. A current tuning loop is suggested to overcome the sizing mismatch error. The master slave concept is used along with this to generate multiple copies of weighted current sources.

Differential Input Area Efficient Current Comparator
2019 IEEE 31st International Conference on Microelectronics (MIEL), 2019Differential input area efficient current comparator for multichannel detector (sensor) applications is presented. Comparator consists of current preamplifier, hysteresis latch, amplifier-voltage limiter and output low-voltage to CMOS translator, having built-in polarity selection switch. The latch geometry was chosen to feature non-zero hysteresis and

Energy efficient current-mode signaling scheme
2010 IEEE Asian Solid-State Circuits Conference, 2010This paper describes a novel energy-efficient current-mode signaling scheme (CMS scheme) for long on-chip interconnects. The scheme was fabricated in 180nm process. Measurement results show that the proposed 6mm long link offers 22% improvement in delay with 81% lower energy consumption at 0.62Gbps over the voltage-mode scheme.

Brushless direct current motor efficiency characterization
2015 Intl Aegean Conference on Electrical Machines & Power Electronics (ACEMP), 2015 Intl Conference on Optimization of Electrical & Electronic Equipment (OPTIM) & 2015 Intl Symposium on Advanced Electromechanical Motion Systems (ELECTROMOTION), 2015The use of a compact lightweight efficient propulsion system is one of the main technological requirements for a long endurance electric Unmanned Aerial Vehicle (UAV). Currently the most popular trend is to use a permanent magnet brushless direct current (BLDC) model motor.

Efficient Current-Based Directional Relay Algorithm
IEEE Systems Journal, 2019Directional relays have a key role for protection of transmission and distribution networks. They are used as supervisory element for distance and overcurrent protections. Therefore, accuracy and performance of these protections are dependent on the performance of directional relays.
