The following robot is a intelligent system as a kind of provisional one, which has robot positions corrective feedbacks, toward the black or white line. In general robots incomes are voltages of the circuits and sensors voltages variations. The robot processor which is a micro AVR chip has been set to read the incomes, compare them to the predetermined amounts and ordering to the motors by the driver and the robot outcomes are to move and change the robot's position toward the line in the best way. The traits of this robot comparing to the last ones in this field includes: increasing man oeuvre power with sudden way point changes, excellent and accurate robot renovation and low price for production. This robot can be use for carrying stuff of information's between two special points like to rooms in an office or in a hospital.

In this paper, an applied mathematical method is proposed in which the effect of second order Intermodulation injection in elimination of the third order Intermodulation is examined and circuit parameters will be achieved with calculation to obtain the best IIP3 response of the circuit. The suggested mathematical technique is applied to a down converter Gilbert cell mixer in 2.4 GHz. This mixer is designed in TSMC 0.18 µm CMOS technology and is simulated using ADS2006A. The operation conditions of the mixer are 1.8 v supply voltage and total current consumption of 2.7 mA. The proposed mixer provides 11 dB conversion gain and 11.1 dB SSB noise figure. This mathematical linearization method causes IM3 to reduce to 14.4 dB and increases IIP3 from 1 dBm to 8 dBm. This technique does not have a significant effect on conversion gain and noise level of the mixer and only requires a small amount of current about 0.05 mA. By performing this technique the best IIP3 will be achieved with 10% error which is remarkable and shows its high ability in linearization.

The volatility of the oil future price is extremely complex, therefore an accurate forecasting on oil price is an important and challenging topic. This paper presents a GRNN forecasting model for Brent crude oil price. Careful attention is paid on finding number of features as input data to achieve best performance for model. Also to overcome unforeseen critical conditions, a crisis index is defined. The results show that with appropriate selection of the training data and crisis index, the model is capable of forecasting oil price in both normal and critical conditions.

This paper introduces experimental simulation method to the field of innovative talent management in universities by agent modeling. Firstly, the behavior rules for the space and the agents are set, the agent states are defined, and the model is implemented on NetLogo platform. Then a contrastive experiment is carried out to find differences between academic impact-oriented and knowledge innovation-oriented mode. It is found that the latter mode enjoys better systematic efficiency, and some policy suggestions are presented accordingly. The experiment has verified the functions of the model which is proved to be effective, showing favorable development prospects in research area.

This paper demonstrates a systematic procedure of system identification, flight control design and robustness analysis for an Uninhabited Aerial Vehicle (UAV). Unscented Kalman Filter (UKF) is used to estimate the aerodynamic parameters with uncertainty bounds and to update the nonlinear model. A linearized model with parametric uncertainties is extracted from the nonlinear uncertain dynamics of the UAV by a new approach. Next, an accurate, equivalent worst-case gain unmodeled dynamic uncertainty model is constructed for the purpose of simplifying the resulting synthesized controller. The system has to be robust against varying system parameters. Two different robust methodologies named H-infinity and Mu synthesis are adopted for control laws development. The robustness of these two controllers is assessed via real-Mu analysis, using a linear fractional transformation (LFT) model with detailed parametric uncertainties. Finally, the nonlinear model analysis shows system performance under uncertainty perturbation by using Monte-Carlo simulation.

Automatic power transmission line inspection with aerial video surveillance requires that the vehicle-mounted camera can automatically locate electricity pylons. In this paper, a new approach for locating electricity pylons within video sequences is proposed. Straight lines in each video frame are extracted with a two-dimensional separable infinite impulse response (IIR) filter and the Hough transformation. A technique for selection of lines representing the electricity pylons is also proposed. The experimental results from a set of real-world video images are shown in term of the receiver operating characteristic (ROC) curve to verify the algorithm's detection performance. The ROC curve shows that the proposed algorithm performs very well and can very much help in the automatic electricity pylon detection system.

The electrocardiogram (ECG) is widely used for diagnosis of heart diseases. Generally, the recorded ECG signal is often contaminated by noise. In order to extract useful information from the noisy ECG signals, the raw ECG signals has to be processed. The baseline wandering is significant and can strongly affect ECG signal analysis. The detection of QRS complexes in an ECG signal provides information about the heart rate, the conduction velocity, the condition of tissues within the heart as well as various abnormalities. It supplies evidence for the diagnosis of cardiac diseases. The signal denoising can be done by Discrete Wavelet Transforms but the results obtained from it are not optimal mainly due to the loss of the invariant translation property. This takes us to the Undecimated Wavelet Transform(UWT) which has invariant translation characteristic, better capacity to reduce noise and better peak detection. In this study, we propose an effective technique for the denoising of ECG signals corrupted by nonstationary noises using UWT, which is implemented with Laboratory Virtual Instrumentation Engineering Workbench (LabVIEW) platform.

In this paper, we report our experimentation to enhance the quality of the thermal images acquired with ordinary digital camera, after replacing the infrared stopping filter with visual stopping one. The Red, Green, Blue histograms indicate very low intensities captured by the respective sensors. Histogram stretching increased the hot objects' and the inherent noise visibility. Finally lowpass as well median filtering were applied, where the later is best for suppressing granular noise and maintaining the intended thermal images.

Clock and data recovery (CDR) circuits using bangbang phase detectors (BBPDs) are widely used in high speed serial links. The BBPD quantizes the phase difference between the input data and the recovered clock, generating a two state output for the loop filter (LF). The two-state output causes the behavior of the BBPD to be highly nonlinear and difficult to analyze. This paper provides a detailed analysis of the jitter transfer for second order bang-bang CDR circuits. Two popular representations of the second order bang-bang CDR circuits are used for our analysis. A detailed derivation of the jitter transfer expression is presented using each representation. Then a modified expression is derived, which is then verified by a phase-domain model implemented in Simulink. Simulation results show good agreement with the derived expression.

Once-through steam generator in concentric annuli tube is a new type steam generator which adopts structure of double-face heat transfer. The model of steam generator is built by lumped parameters with moving boundary. In the basis of the built model, static and dynamic characteristics are analyzed. Because thermal capacity is relatively less, it enhances difficulty of control. On the basis of trails of PID controller and fuzzy controller, fuzzy-PID switch controller is applied to regulate tightly pressure of exit steam, using feed water flow as controlled variable in this paper. A mathematic model of once-through steam generator in concentric annuli tube is derived. The application of designed fuzzy-PID switch controller to once-through steam generator in concentric annuli tube pressure control of exit steam is discussed and simulation results show that this algorithm possesses better dynamic performance and robustness than conventional PID strategy.
