A distributed balanced photodetector with high saturation photocurrent has been experimentally demonstrated. The maximum linear DC photo-current of 33 -ranch is equivalent to 66mA in single ended photodetectors. The AC linearity at high photocurrents is also investigated.

`gym-saturation` is an OpenAI Gym environment for reinforcement learning (RL) agents capable of proving theorems. Currently, only theorems written in a formal language the Thousands Problems Theorem Provers (TPTP) library clausal normal form (CNF) are supported. implements 'given clause' algorithm (similar to one used Vampire and E Prover). Being Python, was inspired by PyRes. In contrast monol...

a periodic increase in blood pressure (bp) occurs during apneic episodes in patients with obstructive sleep apnea (osa). several factors including hypoxemia and an increase in heart rate (hr) were reported to be responsible for this increased bp. to examine the contribution of these two factors in increasing bp, 35 healthy male subjects (mean age±sd= 23.64±3.80) were studied in three experiment...

Various cascode circuits are investigated with regard to their suitability for switched current copier applications. Generalized circuit representations are introduced and different cascode circuits are compared and discussed. A method called “reference voltage and current tracking” for dynamic output range improvement is proposed. An improved regulated cascode circuit with extended dynamic out...

Current and voltage transformers influence the criterion values measurement particularly during disturbances in the system. Certain construction limitations of instrument transformers may in some cases cause maloperation or substantial delay in tripping of the protective relays. Current transformer saturation and discharging of the capacitive voltage transformer’s internal energy during short c...

A two-dimensional, unsteady, isothermal and two-phase flow of reactant-product mixture in the air-side electrode of proton exchange membrane fuel cells (PEMFC) is studied numerically in the present study. The mixture is composed of oxygen, nitrogen, liquid water and water vapor. The governing equations are two species conservation, a single momentum equation for mobile mixture, liquid mass cons...

This paper presents the design of a Current-toVoltage (I−V) and Voltage-to-Current (V−I) converters for use in current-mode analog integrated circuits are described. The proposed I−V converter and V-I Converter has high linear range. The circuit uses MOS transistors in linear and saturation regions to produce an output current linearly related to the input voltage. Both circuits have been imple...

background: today, endoscopic evaluation of digestive system is an important diagnostic approach in gastrointestinal diseases. as it is an invasive method, it causes fear and anxiety in patients. the current study was fulfilled to evaluate the effect of music therapy during endoscopy on the anxiety of patients by measuring blood pressure. methods: this is an experimental study of single blind c...

in this study, a general theoretical model to foresee and calculate the current-voltagecharacteristics in a plateau zone and the associated efficiency of the neutron detector (sensitivity) is presented. this study is to complete the previous studies in this field. the model also considers electric field distortion resulting from the charge collection effect. the characteristics curve is obtaine...
