Turkish Journal of Electrical Engineering and Computer Sciences
of water has significant importance for industry, agriculture, livestock, and health. The system designed and manufactured in this paper measures, displays, and controls the TDS of water by installation on domestic and industrial purification systems. Technology of manufacturing the TDS measurement system is such that it can compensate for the adverse effect of temperature. Calibration of the measurement system will be explained here by discussion of several examinations conducted at the Research Institute of Food Science and Technology of Iran. In order to control TDS, a mathematical model for domestic water purification devices of reverse osmosis (RO) is obtained using …
Effects Of Mica2-Based Discrete Energy Levels On The Lifetime Of Cooperation Neighbor Sensor Networks, Zeydi̇n Pala
Effects Of Mica2-Based Discrete Energy Levels On The Lifetime Of Cooperation Neighbor Sensor Networks, Zeydi̇n Pala
Turkish Journal of Electrical Engineering and Computer Sciences
using Mica2 mote discrete power levels on neighbor sensor network lifetime. We built a linear programming framework to qualify the cooperation of sensor networks using a discrete energy model in comparison to noncooperating networks. Our results showed that a wireless sensor neighbor network that uses a discrete radio model can be more energy efficient than a network that uses a nondiscrete energy model.

Predicting Acute Hypotensive Episode By Using Hybrid Features And A Neuro-Fuzzy Network, Marzieh Abbasinia, Fardad Farokhi, Shahram Javadi
Turkish Journal of Electrical Engineering and Computer Sciences
This paper presents an approach for acute hypotensive episode (AHE) time series forecasting based on hybrid feature space and a neuro-fuzzy network. Prediction was accomplished through a combination of time domain and wavelet features by using six vital time series of each patient, obtained from MIMIC-II and available in the context of the Physionet-Computers in Cardiology 2009 Challenge. At first, statistical time domain features were used and then the wavelet coefficient was utilized for extracting time scale features. Further UTA feature selection was applied and 30 effective features were determined and achieved to predict AHE with 96.30 accuracy 1.5 h …
A Designed Converter For Minimizing Srm Torque Ripple With Controlled Boost Capacitor Automatically, Loghman Samani, Mahdi Abdolhamidi, Amir Rashidi, Sayed Morteza Saghaiannezhad
A Designed Converter For Minimizing Srm Torque Ripple With Controlled Boost Capacitor Automatically, Loghman Samani, Mahdi Abdolhamidi, Amir Rashidi, Sayed Morteza Saghaiannezhad
Turkish Journal of Electrical Engineering and Computer Sciences
Direct instantaneous torque control (DITC) is one way of controlling torque in switched reluctance motors. Despite the presence of DITC control, torque ripple at nominal or higher speeds is considerable due to the back emf increasing. To overcome this drawback, many converters have been proposed. In most convertors proposed for fast excitation in DITC, controlling of boost capacity is an important problem. This paper presents a DITC for a switched reluctance motor using a proposed converter to reduce the torque ripple with controlled boost capacitor automatically. The proposed converter reduces the torque ripple at rated or higher speeds and no …
Design And Implementation Of A Compact Avionics Instrument For Light Aviation, Mustafa Emre Aydemi̇r
Design And Implementation Of A Compact Avionics Instrument For Light Aviation, Mustafa Emre Aydemi̇r
Turkish Journal of Electrical Engineering and Computer Sciences
In this study, a low-cost compact avionics instrument has been designed and implemented for light aviation vehicles such as ultralight airplanes, hang glider-trikes, and paramotors. At the moment there are a few commercial products that provide flight data and vehicle statuses such as altitude, temperature, fuel level, and engine hours meter. However, due to low production rates, customization for different air vehicles, and complex electronics and signal processing hardware, these instruments are generally far from being affordable; their cost may even be more than that of the air vehicle. This study presents a novel approach such that recent state-of-the-art hardware …

Turkish Journal of Electrical Engineering and Computer Sciences
In this paper, the hybrid photovoltaic/thermal collector (PV/T) system's electrical and thermal efficiency was examined by stating a mathematical model and developing a prototype of the system. To enhance the electrical efficiency, the cell temperature of the PV module was decreased with cooling and the heated fluid could be used for low heating applications. For this purpose, a PV/T system was modeled and constructed using a thermal collector placed beneath the photovoltaic panel where the excess heat and solar radiation through the transparent PV module was the input of the thermal collector. A transparent solar module was used in order …
