Generally, there are many of the error evaluation methods which employed for the length measurement system. The reversal error is one of the important sources of the error. Normally, it is compensated by using the linear error compensation but some residual error is found for measurement uncertainty evaluation. This paper presents a method which is a new design of an automated line scale measuring...
This research proposed the improved H-LBP for edge detection, TH-LBP. It applied the Hyperbolic Tanh function instead of the H function. In this method, the continuous and thick edges can be obtained. In addition, the method parameters could be adjusted to increase the edge details in the low contrast area. This method can solve the problem in the case that the two different local areas obtain the...
White-RGB (WRGB) color filter array (CFA)-based CMOS sensor is a new and popular technique to improve the image quality directly with a higher sensitivity White (W) filter. Considering there is no color information in the pixel assigned to W, color separation from W raw data is necessary. We propose a color separation method based on a novel physicallike virtual color filters model for the WRGB CFA-based...
A polyglot synthesizer is a text-to-speech synthesis system, that converts a mixed-language text into speech with single speaker's voice. The straightforward way to develop such a system is to build multiple language-specific synthesizers or to build a single synthesizer after merging common phonemes. In these cases, either language-switching between languages or influence of one language phoneme...
The hybrid fully differential second order Gm — C lowpass filter constructed from an operational transconductance amplifier and a PMOS source follower is presented in this paper. This proposed LPF is simulated using 0.35 μm standard CMOS process and consumes 9.19 nW at 1.5 V power supply for 100 Hz bandwidth. The bandwidth of this proposed LPF is tunable from 10 Hz to 1 kHz. The benchmarks between...
The aim of this paper is to study the effect on eigenenergies due to variation in channel thickness where the channel comprises of a nanoscale symmetric double triangular quantum well (DTQW) separated by a barrier for double heterostructure double gate InAlAs/InGaAs HEMT. The eigenenergies are calculated analytically by solving one-dimensional (1D) time independent Schrodinger equation in the channel...
This paper describes a path planning method for mobile robots/vehicles be extending the path sequentially. Considering practical use and applications of the mobile robot/vehicles, additional via-points for future path are given sequentially from sensor processing and environment recognition process. Thus, the path should be calculated sequentially with such additional conditions during mission execution...
A novel decomposition technique of the forward and backward propagating waves is presented. This technique exploits the Cauchy integral equation based on Clifford algebra application which the integral operators satisfying with Maxwell's equations provide all components of electromagnetic fields along the boundary of the problem. It is able to solve the boundary value problem in the case of partial...
Recently, sensorless controls, which eliminate position and speed sensor in a permanent magnet synchronous motor (PMSM) drive, have been much studied. Most sensorless control algorithms are based on the back-electromotive force (back-EMF) and speed estimations which are obtained from the voltage equations. Therefore, the sensorless control performance is largely affected by the parameter errors of...
Normal blood glucose levels are tightly regulated in the human body, in the range of 70–150 mg/dL. With the increasing awareness that uncontrolled diabetes plays a significant role in the onset and progress of other diseases, severely diabetic patients are being advised to closely monitor their haemoglucose levels, as often as four times every day. This is done in a home environment, by means of a...
A device capable of data logging on/off status of all lamps in a house or office room for the purpose of monitoring energy consumption is described. It is based on 3 components which are a CMOS digital camera, a card type computer board and a WiFi module. An image of the room is taken once every minute and transformed to a two level black and white version from which a simple lamp detection is operated...
A capacitance to voltage convertor for a five-inch touch screen panel is designed. In this paper, a new quasidifferential buffer is proposed to be robust with respect to display noise and highly area efficient. The measurement results show that the signal-to-noise ratio is 29.8 dB when evaluated with a 3.7-inch add-on touch screen panel and LCD display. The proposed circuit, fabricated via TSMC 0...
Designing a system for artistic purposes is a challenging task. As judging beauty is a subjective task, most systems rely on Interactive Evolutionary Computation, which the user takes the tedious task to make evaluation decisions. In this paper, we introduce a texture-based evolutionary art algorithm, as an automatic designer system, using genetic algorithm. We mainly focus on two important parts...
In this decade, WBAN plays vital role in health care monitoring environment. It has been used more intensively in wider applications. This paper proposes error control coding applied to WBAN. LDPC codes with the block size of 255 bytes are particularly of interest. Patterned information such as MIT-BIH's arrhythmia datasets extracted from Electrocardiography (ECG) of the patients who encountered heart...
Engineers and scientists currently know how to make silicon solar cells that are 25% efficient. This achievement has nearly reached the theoretical maximum (29%) for a single junction solar cell. How do we go beyond 29%? In order to continue reducing the costs of solar power generation, higher performance devices are necessary. Here we briefly present possible strategies along with their implementations...
In this paper, q-Bessel polynomials for linear phase matched filter is presented. In order to approximate a receiver filter with optimum performance, a raised-cosine test pulse is utilized. A transfer function of the proposed matched filter at receiver consists of transmission zero pairs and q-Bessel polynomials used as a linear phase denominator. Simulation results show that the performance of the...
Recently, with the innovation of modern medical technology, the elderly population has been rapidly increased than before. In the past, without the Internet technology, the elderly must spend their life in the nursing home even though they are not in any serious sickness due to the expensive wage of the personal curator. Fortunately, nowadays, the capability of mobile phone and the quality of networking...
