The aim of this paper is to confirm the result of treatment of benign prostate hyperplasia (BPH) using microwave balloon antenna. In this paper, we performed in vitro experiments using microwave with frequency of 2.45 GHz to generate heat on urethra porcine tissue. The results revealed that the area around urethra tissue was not severely burned. Urethra tissue evidently expands from pathological examination...
This article is purpose of the computational fluid dynamic (CFD) simulation for blood parameters separated by centrifuge machine which has different spinning velocities. The structure of the machine, as a fixed tube at 30 degrees from the base is used to prove that the precipitate of the blood's 2 parameters, such as blood cell and plasma, by using the simulation from computer In three dimensional...
This article studies the behavior of human sleep found the insufficient sleep problem due to the brain performance. This experiment uses devices such as sleeptracker to save the results of a sleep and electroencephalogram (EEG) to detect brainwaves while enjoying music. However, this study considers only a general sleep and sleep event that a relaxed with the music. The findings indicated the music...
It was realized that cancer in breast is one of the most health hazards threatening women around the world for many years. Thermal ablation by using microwave energy is another alternative surgical maneuver due to its minimally invasive therapeutic technique. In this research, we investigate an effect of phase difference between three adjacent openedslot coaxial probes in a multiple antenna alignment...
This paper presents a new versatile multifunction voltage-mode biquadratic filter with three inputs and four outputs employing single-ended operational transconductance amplifiers (OTAs) and grounded capacitors. The proposed circuit provides the following advantages: (i) employment single-ended OTA and grounded capacitor which is highly suitable for integrated circuit implementation, (ii) simultaneously...
A new current-mode four-phase quadrature oscillator circuit using a single modified current controlled current conveyor transconductance amplifier (MCCCCTA) and two grounded capacitors is presented. The oscillator provides four current outputs with 90° phase difference from high output impedance terminals. The condition of oscillation and the frequency of oscillation can be electronically and orthogonally...
In this paper we investigate the electromagnetic field interaction with a glucose aqueous solution using a microwave antenna (U-shape) to evaluate the glucose concentration and vary temperature. The glucose concentration vary from 10–40 mg/ml compare with DI(de-ionized) water, the operating frequency of about 1–2.5GHz. The change of the glucose concentration is directly related to the change of the...
This paper presents an improvement of deterministic WLAN location determination system using finite element method for calculated HEF constant, ones to add the last value before decision of conventional method. From the results, when using HEF, constant improved the value before decision position for LLR and RADAR yielded to be obvious. It had minimum error distance below 2 meters.
In this work, quartz crystal microbalance humidity sensor was fabricated by inkjet printing technique. Poly (3, 4-ethylenedioxythiophene)/poly-styrene-sulfonic acid (PEDOT/PSS), one of the most widely used polymer composites, was printed on QCM electrode as sensing layer using Dimatrix material inkjet printer. The main advantage of this coating method is its high precision of solution coating with...
This paper presents a new current-controlled mixed-mode quadrature oscillator using only a current controlled current differencing transconductance amplifier (CCCDTA), two grounded capacitors and one MOS resistor. The structure is beneficial to monolithic integrated circuit implementation. The proposed circuit provides two quadrature voltage outputs and two quadrature current outputs. The quadrature...
