In this paper, a radiation model of Magnetic Flux Compression Generator with capacitive load is proposed based on the electrically small loop antenna theory, which can help to predicting the radiation characteristics of Magnetic Flux Compression Generator with capacitive loads and providing the necessary guidance on performance improvement and their experiment. The approximate calculation is necessary, however, by this approximation; the radiation efficiency can be a general assessment.

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.

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.

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.

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.

The purpose is to apply the algorithm in the 3D orthodontic diagnosis and treatment software package. The method consists of 5 main steps as follows. First the digital dental model is produced by 3D scanner in STL format and the occlusal plane is calculated. Second the arch form of the model is approximated. Third the panoramic of the dental cast in 3D system is constructed. Fourth, the 3D-panoramic is converted to 2D system to find the cutting points for segmentation of individual tooth, and finally the 2D image is converted back to 3D system for creating the vertical plane for separating teeth into difference colors at the cutting points. The result has shown that the 3D digital dental model can be segmented for separating individual tooth, and the algorithm is ready to apply in orthodontic diagnosis and treatment software package.

In recent years Operational Transconductance Amplifier (OTA) based integrated circuits, filters and analog circuits have been widely investigated. The usefulness of OTAs over conventional OP-Amps in the design of active circuits are well documented. This paper presents a new sinusoidal frequency-to-voltage converter which can linearly convert low voltage signals which is not possible with commercial converter ICs such as LM2917. This converter is based on an OTA based differentiator and an OTA based half wave rectifier.

In the past few years, a number of image cryptosystems have been proposed. However, many of them have been shown to be insecure. In this paper we present a robust and efficient cryptosystem based on the synchronization of a chaotic time delay system to transmit a digital image in a secure way. It consists of two steps: the first one assures the transmitter/receiver synchronization, the second step focuses on the encryption/decryption procedure. The transmitter module consists of a chaotic generator which is the time delay feedback Chua circuit and an encryption mechanism (chaotic masking), in which the secret message (digital image) is added to the output of the chaotic generator. The receiver module consists of a nonlinear state observer design which is driven by only one of the states of the time delay feedback Chua circuit and a decryption mechanism. A secure analysis proves that this cryptosystem is robust to some best-known attacks. This efficiency relies to the properties of the chosen chaotic generator and the efficiency of the nonlinear observer.

In this work, we propose the architecture of hybrid intrusion detection system (eHIDS) for wireless sensor networks. In order to get hybrid scheme, we use combined version of anomaly and misuse detection techniques. In addition, we use cluster-based wireless sensor networks to reduce communication and computation costs. We evaluate the performance of our scheme by simulating the network and comparing with other related schemes. The simulation results show that our scheme performs better than other schemes in terms of energy efficiency and high detection rate.
