Ultrasound images and ultrasound imaging method is an effective method in examining the challenges, problems and diseases related to the breast in women. The contrast of these images is generally very weak, however, the tumor tissue and calcium grains are evident in it. Methods based on image processing are widely used in breast tumor diagnosis […]
The unique properties of carbon monoxide and its high combustibility have led to the creation of various sensors, such as electrochemical sensors and different circuits, to read its output. In this article, a deflection-type Wheatstone bridge is used to measure changes in the sensor resistance, and the output voltage is connected to a 12-bit analog-to-digital […]
Kinship verification is a process that two or more people has a family relation such as father and son or other family relation. Numerous studies have been presented to investigate the relationship between people. Kingship verification can be done based on image of face. Most of the methods presented on face images work well on […]
In this article, a two-dimensional photonic crystal-based XOR gate is designed and simulated. For this purpose, an initial two-dimensional photonic crystal structure is chosen and waveguides are created for inputs and outputs. Then, defect rods are selected so that the obtained outputs are approximately consistent with the XOR gate truth table. After that, we will […]
For accessing to higher speed and more densities in packaging, FET structures have become small increasing from day to day. Devices as small as 18nm can still exhibit acceptable transistor characteristics but At such small sizes, the nature of carrier transport in the device begins to change. In such MOSFETs that the device size becomes […]
Software testing is one of the most important phases in the software development procedure which ensures the accordance of the software and its description. Testing is mainly a manual task accomplished by the human operators. This results in increasing the cost and time of the software development process. Also, due to the uncertain nature of […]
In this paper we propose a good way to decrease the effects of noisy channels on the JPEG images using multiple description coding. In this way we can compress the data of image with a better signal to noise ratio. first, we use over sampling to increase the redundant of the data, then we divide […]
In this paper a new sliding mode controller based on predictive control is used for the first order system, which is a good model for the industrial process. In this method a developed predictive control is used to optimize the sliding mode control including sliding surface and switching function coefficient at every moment. A new […]
Location awareness is an important capability for a series of enhanced wireless businesses. sensor networks are dense wireless networks of small low cost sensors, which collect and disseminate environmental data, for monitoring, military application and so on. Localization is an unconstrained optimization problem. position estimation is based on various, distance / path measures, which include […]
Permanent magnet synchronous motors attract more attentions in motion control application in recent years. In this paper a novel stator flux oriented vector control scheme with maximum power factor to current trajectory is presented for a permanent magnet synchronous motor. This system is then implemented in Matlab/Simulink and the motor performance under this control method […]
