wet ag/agcl electrodes, although very popular in clinical diagnosis, are not appropriate for expanding applications of wearable biopotential recording systems which are used repetitively and for a long time. here, the development of a low‑cost and low‑noise active dry electrode is presented. the performance of the new electrodes was assessed for recording electrocardiogram (ecg) and electroence...
A new radio frequency (rf) linear accelerator (LINAC) system with high efficiency has been developed by AIBT. The general designs of such a rf LINAC system are briefly discussed. This system includes a plurality of resonators each including an inductor circuit that is connected to at least two rf electrodes. Detailed designs of a system where two of the adjacent rf electrodes are connected to t...
In this paper design and simulation of an optimized accelerator tube is presented for the production of light charged particles up to energy of 2 MeV. Geometry of the accelerator tube electrodes was simulated based on the Van De Graaff accelerator tubes of Atomic Energy Organization by SIMION 7.0, Virtual Device and SIMION Toolkit codes. In accelerator tube, the extracted ion beam from the ion ...
Lateral growth of one-dimensional nanostructures is crucial for high performance field-effect transistors (FETs) which can drive a high on-current that is proportional to the number of nanorods (NRs) aligned between electrodes. Hence, it is strongly required to laterally and directly grow a large number of NRs between electrodes. For the first time, we propose a polyhedral-type FET (PH-FET) bas...
different researchers in different parts of the world have investigated the strategies used to translate written works ranging from novels to classroom assignments. however, by the significant increase in the number of postgraduate students in iran in the last few years, a very common kind of translation in iran includes translating abstracts of master’s theses. in this work, the researcher hav...
Speech recognition was measured as a function of spectral resolution (number of spectral channels) and speech-to-noise ratio in normal-hearing (NH) and cochlear-implant (CI) listeners. Vowel, consonant, word, and sentence recognition were measured in five normal-hearing listeners, ten listeners with the Nucleus-22 cochlear implant, and nine listeners with the Advanced Bionics Clarion cochlear i...
Abstract A simple and generic model for the heat distribution in electrodes primary metal production has been investigated. The equations have analyzed focusing on understanding scale-up of under both direct current (DC) alternating (AC) conditions. analysis provides a theoretical foundation Westly’s empirical rule. For graphite small carbon electrodes, current-carrying capacity is limited by o...
Objective: In neural response telemetry, intracochlear electrodes stimulate the auditory nerve and record the neural responses. The electrical stimulation is sent to the auditory nerve by an electrode and the resulted response, called electrically evoked compound action potential, is recorded by an adjacent electrode. The most important clinical applications of this test are evaluation and moni...
Widespread application of cochlear implants is limited by cost, especially in developing countries. In this article we present a design for a low-cost but effective cochlear implant system. The system includes a speech processor, four pairs of transmitting and receiving coils, and an electrode array with four monopolar electrodes. All implanted components are passive, reducing to a minimum the ...
Membrane capacitive deionization (MCDI) is a technology for water desalination based on applying an electrical field between two oppositely placed porous electrodes. Ions are removed from the water flowing through a channel in between the electrodes and are stored inside the electrodes. Ion-exchange membranes are placed in front of the electrodes allowing for counterion transfer from the channe...
