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 …


Fast Measurement Of Headlamps By Means Of A Developed Fuzzy Luxmeter Based On A Fuzzy Mapping Algorithm, Mustafa Şi̇nasi̇ Ayas, İsmai̇l Hakki Altaş, Turhan Alçeli̇k Jan 2016

Fast Measurement Of Headlamps By Means Of A Developed Fuzzy Luxmeter Based On A Fuzzy Mapping Algorithm, Mustafa Şi̇nasi̇ Ayas, İsmai̇l Hakki Altaş, Turhan Alçeli̇k

Turkish Journal of Electrical Engineering and Computer Sciences

headlamps in the dark is inferable from the results of studies. Various regulations are available in order to arrange the required illuminance values at certain positions on the road. The designed and produced headlamps have to satisfy the requirements of these regulations. Manual measurement tools, such as the luxmeter (which are based on point-by-point measurements), have traditionally been used. This traditional way has been considered inefficient in terms of awkward setup procedures, complexity, the continuous intervention of human operators, and costs. In this study, in order to overcome these problems, a new approach for measuring the illuminance values is proposed. …


Abnormal Event Detection In Crowded Scenes Via Bag-Of-Atomic-Events-Based Topic Model, Xing Hu, Shiqiang Hu, Lingkun Luo, Guoxiang Li Jan 2016

Abnormal Event Detection In Crowded Scenes Via Bag-Of-Atomic-Events-Based Topic Model, Xing Hu, Shiqiang Hu, Lingkun Luo, Guoxiang Li

Turkish Journal of Electrical Engineering and Computer Sciences

crowded scenes. A new concept of atomic event is introduced into this framework, which is the basic component of video events. Different from previous bag-of-words (BoW) modeling-based methods that represent feature descriptors using only one code word, a feature descriptor is represented using a few more atomic events in bag-of-atomic-events (BoAE) modeling. Consequently, the approximation error is reduced by using the obtained BoAE representation. In the context of abnormal event detection, BoAE representation is more suitable to describe abnormal events than BoW representation, because the abnormal event may not correspond to any code word in BoW modeling. Fast latent Dirichlet …


Relay Sliding Mode Control Based On The Input-Output Model, Şölen Kumbay Yildiz, Hüseyi̇n Demi̇rci̇oğlu Jan 2016

Relay Sliding Mode Control Based On The Input-Output Model, Şölen Kumbay Yildiz, Hüseyi̇n Demi̇rci̇oğlu

Turkish Journal of Electrical Engineering and Computer Sciences

In this study, the relay sliding mode control method based on the input-output model proposed in previous studies is revisited. Sliding conditions under ideal operating conditions are reformulated to fortify the theoretical background. Some additional issues, namely the effects of disturbances and measurement noise on the sliding mode conditions, are addressed and analyzed in detail. Finally, the theoretical results are put to the test by detailed simulation examples.

Novel, Graded, Priority-Oriented Admission Control In Mobile Networks, Siddu Payappa Algur, Niharika Kumar Jan 2016

Novel, Graded, Priority-Oriented Admission Control In Mobile Networks, Siddu Payappa Algur, Niharika Kumar

Turkish Journal of Electrical Engineering and Computer Sciences

to the different services in mobile broadband networks (WiMAX, LTE). A new connection is admitted only when the network can support the QoS needs of the connection without degrading the QoS for existing connections. An efficient call admission control algorithm ensures higher throughput and fewer delays for the admitted connections. In this paper a graded priority-based call admission control algorithm is proposed for LTE and WiMAX networks. The number of permissible connections shall be segregated into two classes. The new connection shall be graded, prioritized, and admitted based on the device requesting the connection. Simulation results show that graded priority-based …

Turkish Journal of Electrical Engineering and Computer Sciences

realization of an experimental prototype. A Maxwell model of the system was constructed and finite elements analysis (FEA) was applied before building the experimental prototype. The effect of variations in projectile parameters (such as material and length of the projectile) on projectile velocity was studied using the model. Then the experimental prototype of the launcher system was built. A velocity measurement system was also designed and implemented to measure the muzzle velocity of the launched projectiles. A total of 9 projectiles of 3 different sizes made of 3 different materials were constructed to be launched by the system. Each projectile …

power quality problems due to the fluctuating nature of the wind and the increasing complexity of the power system. This paper describes a novel approach to voltage and power control of a radial electrical distribution network, using a wind farm. The wind farm consists of seven 75 kW induction generators (DFIG) supplying two AC/DC converters. The feed structure of the DFIG allows operating the system conversion in a wide range of speed variations. That is why it is a recommended solution, due to its capacity to increase the generator power to twice its nominal power; consequently, the system's size and …
