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 …

Today, power consumption presents a critical issue when designing embedded systems. It has become a key factor in a product's success when being marketed, especially for mobile systems. In this paper, we have developed a typical design for video zoom-in processing with low power consumption. The proposed design has been implemented on the Xilinx Virtex-5 with the integration of different important resources like embedded processor, embedded memory, MPMC, DDR, and various interfaces. The design results show a significant gain in power at the simulation level as well as the physical one. In addition, the proposed design provides an important gain …

Parametric-Based Mobility For Providing Opportunistic Geocasting In Spatially Separated Wireless Sensor Networks, Selvi Ravindran, Narayanasamy Palanisamy, Vetriselvi Vetrian
Turkish Journal of Electrical Engineering and Computer Sciences
Uneven deployment and environment constraint leads to the formation of a spatially separated wireless sensor network (SS-WSN). Most of the traditional WSN architectures consist of static nodes that are densely deployed over a sensing area and are fully connected. SS-WSN is a group of disjoint subnetworks where connectivity is generally maintained by energy rich mobile nodes (ERMN), which roam about from one subnetwork to another. We propose an algorithm whereby the mobility of ERMN helps in distributing the geo message opportunistically in the region of interest. The routing consists of two phases: (1) transmission of the geo message from the …

An Improved Digital Image Watermarking Scheme Using The Discrete Fourier Transform And Singular Value Decomposition, Justin Varghese, Saudia Subash, Omer Bin Hussain, Krishnan Nallaperumal, Mohammed Ramadan Saady, Mohamed Samiulla Khan
Turkish Journal of Electrical Engineering and Computer Sciences
The paper presents an improved digital image watermarking algorithm by incorporating the discrete Fourier transform (DFT) and singular value decomposition (SVD). The Fourier transformed carrier image is decomposed into four different frequency subbands by the proposed onion peel decomposition (OPD) algorithm and the SVD-based watermarking scheme is applied to attach the transformed watermark in all four carrier subbands. The proposed inverse OPD algorithm together with inverse DFT is utilized to reconstruct the watermarked image from the frequency blocks. The watermark extraction algorithm is simple and it performs the inverse of watermarking process. The experimental analysis on different images shows that …

Turkish Journal of Electrical Engineering and Computer Sciences
Maintaining data consistency between data cached by a mobile client and data residing in the data server is a major issue in a wireless mobile environment. In this paper, we propose a push-pull cache consistency (2P2C) mechanism, with the intention of increasing the rate of serving requestors with recent up-to-date information or data from the cache of the intermediate nodes that are exact replicas of the data present in the origin server. This is a hybrid scheme that does not rely entirely either on the server or on the mobile client for maintaining consistency. Here we employ a registration process. …

This paper proposes a model for supporting electrical engineering with e-learning. The model development is based on survey data collected from representative teachers and students studying in higher education institutions in Turkey. To develop the model, the study investigated the attitudes of the representative key stakeholders in the relevant higher education institutions towards e-learning by administrating questionnaires and interviews with teachers and students. The responses of the teachers and students were then compared. Based on the results, a model was proposed with a multidimensional approach to e-learning. The model flips electrical engineering to make sure that the students review, discuss, …

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 …

Wireless sensor networks have grown from homogeneous network architecture to heterogeneous networks for the improvement of network efficiency and lifetime. This paper exhibits a mobile cluster-head data collection (MCHDC) model for heterogeneous wireless networks. The MCHDC model illustrates the mobility pattern of mobile cluster-head nodes in a controlled environment with uniform and nonuniform deployment of mobile elements in the area of observation. It focuses on the threshold velocity for movement of mobile elements in the network area. In this paper the effects of data sending rate, network area, sensor node density, and cluster-head node density on energy efficiency of the …
