In this paper we propose a boosting regression model for time series using BP network and SVR as basic learning methods. We first make brief introduction on BP network and SVR, then give the specific boosting regression algorithm with theoretical analysis. In the experiment, we use a time series data of wind-speed from a coal mine as a training set to verify the efficiency of our proposed method. The experiment results show that boosting regression gain better performance on test training and generaliz ation.

In this paper, a 3.9GHz tunable dielectric resonator oscillator (DRO) with low phase noise is presented. To minimize the phase noise of the oscillator, a high Q-factor tunable dielectric cavity resonator operating in the TE011 mode is designed. Analytical equations are derived to determine the resonant frequency of the cavity resonator. The calculated results and simulated ones by HFSS software are in agreement within 2 percent. A tuning metallic lead with threads is used to tune the first TE011 mode resonant frequency of the cavity resonator and move the spurious HE111 mode resonant frequency farther without significantly affecting the Q-factor. 13.5dB gain two stage low noise amplifier which offers a circular power 6dBm is designed to sustain the oscillator closed-loop loss. In order to occur oscillating, a mechanically tunable phase shifter is also applied. Phase noise levels of -112dBc/Hz and -136dBc/Hz are obtained at offset frequencies of 10 and 100 kHz in practical oscillator noise measurement.

Estimating network topology is a non-trivial task. Different from the state-of-art methods such as traceroute-like active probing, network tomography and network protocols analysis based passive measurement, this work proposes a novel method to estimate the network hidden topology using time to live (TTL) values extracted from IP packets. TTL contains the information about hops of the forward paths which can be fused to reconstruct the topology. The proposed estimating algorithm is described and its performance is illustrated using topology simulation data. Experimental results demonstrate the effectiveness of the newly developed technique.

This paper presents a new capacitive signal-conditioning interface, employing a Phase Locked Loop (PLL) circuit. The entire circuit design is based on the principle of capacitance-frequency-voltage conversion. The CD4046 digital phase-locked loop (Fairchild Semiconductor) was used for the circuit implementation since it offers approximately 1% linearity, which is suitable for most applications [1]. The functional sensor material used was Polyvinylidene Fluoride (PVDF) and this was mixed with 7wt.% Ethyl Cellulose and 1wt.% Lecithin. Terpinol-α was used as the solvent to form the thick film paste. The circuit sensitivity has been tested with the developed thick film sensor in terms of output circuit voltage versus capacitance change. It was found that the developed circuit has lower power consumption when compared to standard frequency-to-voltage converter configurations.

A TE-Optical switch based on transmission properties in square-lattice photonic crystals with a unit cell made of a rotated square cylinder and four horizontal thin plates and a modified one in which tubes filled with air are used instead of thin plates are investigated. The bandgaps are modified when the thin plates are replaced by the tubes, leading to the TE-optical switch function. The switch has been designed and studied by the plane-wave and finite-difference time-domain simulations. For the TE-optical switch, the extinction coefficients reach to -17dB, -30dB, and -38dB, respectively. The proposed optical switch is good for optical integrated circuits.

Air-ratio relates closely to engine emissions, power and fuel consumption among all of the engine parameters. The thesis proposed an online time-sequence incremental and decremental least-squares support vector machines (OLSSVM) for engine modelling to predict the air-ratio. Experimental results show that the proposed OLSSVM can effectively predict the air-ratio to the target values under varies operating conditions and is superior to the air-ratio models available in the recent literatures. Therefore, the proposed OLSSVM is a promising scheme for automotive engine modelling.
