This study used two different Artificial Neural Networks (ANN) to determine the point on a computer screen that the user is looking at. First, an ANN, called ANN1 was developed to identify the eye region of a laptop user from a webcam image. The computer screen was then divided into 57 × 32 blocks of 24 × 24 pixels. One hundred of these were random...

In this study, the aim is to extract the attributes of the eye regions of laptop users. To achieve this, the iris and eye corners are detected by processing the images captured by the standard internal webcam of a laptop. In addition, an artificial neural network (ANN) is used for determining the eye region. Hereby, the iris and eye corners can be...

In this paper, a new nonlinear and adaptive backstepping speed tracking control design was proposed for a Permanent Magnet Synchronous Motor (PMSM). All the parameters in both the PMSM and load dynamics were considered unknown. It was assumed that all state variables are measurable and available for feedback in the controller design. The final cont...

In this study, is aimed to estimated of the region which observed on the screen by the artificial neural network (ANN) trained with using images of laptop user. Study were formed of two phases. In the first stage, an ANN has been developed for determining eye region in the captured image with webcam. In the second stage, the data obtained from the...

In this study, a new nonlinear and full adaptive backstepping speed tracking control scheme is developed for an uncertain permanent magnet synchronous motor (PMSM). Except for the number of pole pairs, all the other parameters in both PMSM and load dynamics are assumed unknown. Three phase currents and rotor speed are supposed to be measurable and...

Today, the use of digital videos instead of analog ones has become much popular due to their easy recordability and low-cost storage. Hence, huge amount of...

In this study, the half wave symmetrical Space Vector Pulse Width Modulation (SVM) is employed in a v/f controlled three phase induction motor drive system with the intention of reducing harmonic components of the three phase currents feeding to the induction motor windings without using any artificial intelligence algorithm. The most important par...

This paper proposes a new speed and current control scheme for a Permanent Magnet Synchronous Motor (PMSM) by means of a nonlinear and adaptive backstepping design. All the parameters in both PMSM and load dynamics are considered unknown. It is assumed that all state variables are measurable and available for feedback in the controller design. The...

In this study, a computer and microcontroller based fuel control system for four-cylinder internal combustion engines has been designed and some applications have been implemented. Fuel control system designed for real time control the amount of fuel in alternative fuel applications. System is suitable to use with both diesel and petrol engines. A...

The increase in complexity of current VLSI-based FPGA arrays has lead to a demand for efficient methods of estimating their performance characteristics at a higher level. This paper describes a technique for speed and area estimation of DSP-based FPGAs, using the example of a primitive operator filter FPGA, which targets the realisation of reduced...

A number of configurable arithmetic structures for an FPGA architecture for the realisation of low complexity digital filters are investigated. The FPGA is based upon primitive operator design technique in which digital filters are realised using signal flow graphs comprising low complexity operations. The authors evaluate the structures with a num...

An architecture for a primitive operator FPGA is proposed in this paper. The performance of two CALB architectures, CALB1 and CALB2, has been investigated in terms of their operation speed and chip area. The CALB 1 architecture offers the advantage of faster speed of operation whereas the CALB2 architecture offers the advantage of reduced chip area

Watchdog Timer birimi, FPGA (Alan Programlanabilir Kapı Dizisi) gelitirme platformunda gerçeklemek üzere HDL formatında ifade edilmitir ve gerçekleme ilemleri süresince 8051'in orijinal...

Today, the use of digital videos instead of analog ones has become most popular in terms of their easy recordability and low-cost storage. Hence, huge amount of digital video archives have come out dramatically. The meaningful search in a video has been an important demand in order to access the video database very fast. While the standard picture...
