In this paper, an adaptive reduced-rank filtering approach based on joint optimisation of adaptive filtering is proposed for the design of the projection matrix of reduced-rank filter and adaptive affine projection algorithm. We introduce how to derive an adaptive reduced-rank affine projection algorithm with the method of joint optimisation and Lagrangian criteria. Simulation results show that the...
This paper presents the RF identification (RFID) reader antenna design for the frequency band of 2.4–2.5 GHz corresponding to the standard of universal SHF RFID. A suspended fractal antenna is introduced in this work. The antenna structure consists of two layers. The bottom plate is suspended above a ground plane. The antenna has a single feed by a tapered down feeding strip. The top layer consists...
In this paper, stability analysis of fully-differential active-RC filters with common-mode feedback (CMFB) networks connected at either the input and output terminals of the fully-differential op amps is presented. The results of such analysis, which were confirmed by simulation results, would enable the trading-off during the design process of the fully-differential active-RC filters to be more effective.
Golf is a popular sport for exercise or socializing. It affects an increasing number of patients. Because of these reasons the researchers decided to focus on this problem. We presented the analysis golf swing using K-Means Clustering with Two-Sided Confidence Intervals and the Closest Pair of Points Problem. The raw data were clustered by K-Means Clustering. The boundaries of subgroups processed...
Electromagnetic wave (EM wave) is necessary for human daily life because EM wave can be applied for various applications such as radio, TV, tablet, wireless, LAN, bluetooth and microwave devices. Electromagnetic wave may interfering signal with the operation systems in medical equipment and communication systems in aircraft. Titanium dioxide (TiO2) is an electromagnetic wave absorber. In this study,...
In this paper, a new modified PWM (pulse width modulation) control method for any type of neutral point clamped (NPC) multilevel inverters is proposed. In NPC inverter topologies with more than three-level, the problem of charge balance in the split dc-link capacitors is still discussable. Hence, the most important advantage of the proposed pulse width modulation (PWM) control method is keeping the...
In this paper, two new structures for current-fed switched Z-source inverters (CSZSIs) are proposed. The proposed structures have the same number of the elements. The proposed structures have less passive elements in comparison with the conventional current-fed Z-source inverters (CZSIs). In the first proposed topology, the input current source has common earth with inverter section. The performance...
The probabilistic model of the random variation in drain current of the nanometer multiple input floating-gate MOSFET (MIFGMOSFET) has been proposed in this research. The modeling process has taken the major physical level causes of random variations e.g. random dopant fluctuation and line edge roughness etc., into account. The proposed model have been found to be very accurate since it can fit the...
This paper presents the development of encrypted near field communication data exchange format transmission in an NFC passive tag for the feasibility of implementing a genuine product authentication. We present a method of checking the genuine product into four major categories: Concept, infrastructure, development and applications. The results show that the passive NFC-forum type 2 tag can be configured...
This paper compares the capacitor voltage by numerical simulation using the Euler integration technique, the trapezoidal rule (the same format used by EMTP) and also the simulation using the EMTP-ATPDraw program. A 115/22 kV transformer supplies a resistive load which is connected in parallel with the switchable capacitor bank has been modeled. The capacitor voltage from EMTP approach is exactly match...
Stop words occur multiple times in a document and the occurrence of stop words have least semantic value in the document sentences. These words cover a noteworthy bundle of archives that have no semantic significance. So, the stop words ought to be removed for better language description. In this paper, we have proposed a proficient algorithm which will eliminate the Urdu document stop words. Many...
Up until now, law violation and drowsiness have been major causes of road traffic accident in Thailand. This study presents an approach to detect the risk due to drowsiness and distraction of a driver. In our method, techniques in computer vision are employed to extract facial features of the driver to determine his behaviors. Since the vehicle speed is also an important factor of the accident risk,...
The performance or output current of a transformer is subject to the load that it is connected to, which may be full, empty, or unusually excessive. Sometimes an overload may be unavoidable, such as in the case of a full load or an above normal load under which the transformer may carry an excessively high current and may result in a huge loss in the form of excessive heat. This will undoubtedly affect...
In this paper, a new method for generating high dynamic range (HDR) image is introduced. The proposed method can automatically fuses the input images of the same static scene with different exposure levels. Firstly, the saturation of the input image is solely used in this method. Since the saturation is similar to contrast, the weighing factor for blending the input images is determined by the mean...
This article proposes a novel technique to simultaneously optimize several performance indices of a swing-up stabilizer using genetic algorithm. The design purpose is to attain a desired performance of the system by minimizing an optimization index containing steady-state error, overshoot, settling time and rise-time of the response. Then, by minimizing the cost function using genetic algorithm, the...
With the development of software and devices for next generation sequencing, a vast amount of bioinformatics data has been generated recently. Also, bioinformatics data based big-data technology is rising rapidly as a core technology by the bio-informatician, biologist and big-data scientist. Especially, most big data analyses are based on network analyses because it can discover characteristics and...
Multiplayer Online Battle Arena or MOBA is one of the most popular game types at the present. The MOBA games have been developed from Real Time Strategy (RTS) games. The goal of MOBA games is to destroy the enemy main base or to get points by killing the enemy members up to the required number. Players of MOBA games usually practice their game skills by playing with a bot. As creating a bot is difficult...
A robust observer-controller structure for sensor fault-tolerant control is proposed for DC servomotor drives. Incipient sensor faults are considered and detected using the Higher Order Sliding Mode (HOSM) observer, followed by a tracking controller which maintains the acceptable drive performance. A fractional Integral Terminal Sliding Mode (ITSM) surface with HOSM terms is considered for the speed...
The aim of this paper is to build android-based gardening robot that can be controlled by Android-based smartphone via long distance. Moreover, the robot can be used to check humidity of the soil and sending the information to a cloud server. The information from the server will be used in the fuzzy algorithm to determine plan of the planting for the user. In the present study, two Android based smartphone...
