Data mining has been used as a public utility in extracting knowledge from databases during recent years. Developments in data mining and availability of data and private information are the biggest challenge in this regard. Privacy preserving data mining is a response to this big challenge. The main purpose of techniques and algorithms in privacy […]
Meta-heuristic methods are global optimization algorithms which are widely used in the engineering issues, nowadays. In this paper, a new stochastic search for optimization is presented using variable variance Gaussian distribution sampling. The main idea in searching for algorithm is to regenerate new samples around each solution with a Guassian distribution. Numerical simulations have revealed […]
Recent advances in the field of electronics and wireless telecommunications have created the capability and potential for designing and manufacturing sensors which have low power consumption, small size, reasonable price and various applications. These small sensors, which based on their type, can perform different tasks such as receiving environmental information, processing it and then sending […]
Design of a very compact two stage amplifier is proposed by merging passive frequency compensation with a feed forward compensation technique, which achieves significant improvement in gain-bandwidth product (GBW), slew rate and phase margin with lower supply voltage requirement. The mathematical analysis given in this paper justify that the proposed technique offers the advantage of […]
A ubiquitous device-widely used in many industrial applications is Computer Numerical Control (CNC) machinery. CNC controller constitutes the main part of a CNC machine, which performs the task of controlling and navigating the tool and implementation of industrial processes. Although there have been many controllers, designed and used, in CNC applications in recent years, most […]
Nowadays the demand for receiving the high quality electrical energy is being increasing as consumer wants not only reliable but also quality power .The usage of automated equipment are increasing and far more susceptible to disturbances compare to the previous generation equipment and information systems. With the deregulation of the electric power energy market, the awareness […]
The purpose of this paper is to design an adaptive neuro-fuzzy controller to control the speed of the BLDC motor. This paper throws overall view of the performance of fuzzy PID controller and compares with fuzzy – adaptive neural controller. Take characteristics of suitable in PID controller is difficult. But fuzzy is the ability to […]
From the viewpoint of technology-driven custom apparatus, the dynamic voltage restorer (DVR) has been identified to be the most prominent device which can be engaged to compensate the voltage sag. On the other hand, this device has been customarily used in power distribution system to protect sensitive loads from sudden voltage sag. Owing to the […]
Current starved delay elements (CSDEs) are among the popular architectures to manipulate rising or falling edges of signals in order to meet timing requirements. The digitally controllable generations of these topologies are now monotonic and reasonably power efficient, but they lack linearity in full range. Inherently, this subject may not seem problematic because by setting […]
In this paper a low-noise amplifier with 0.6 V supply voltage, low power consumption, and improved linearity at= 5 GHz is introduced in 0.18 µm CMOS technology. By using a feed-forward structure and a multi-gated configuration in the proposed circuit, linearity of the circuit is significantly improved, while only 122 µW more power is consumed […]
