In this research, we propose a method executing the particle filter (PF) and the parametric eigenspace method (PEM) simultaneously. Namely, the PEM is used as a re-sampling method of the PF. Since the PEM is executed at the same frequency as the number of particles, high-speed execution of the proposed method is possible. Moreover, since the posture of the object can be estimated by using PEM, the position of the moving target object at the next time frame can be estimated in high accuracy. We apply the method to the real vision image, and examine the effectiveness and the performance.

A backstepping design for an aircraft described by rigid body dynamics is proposed. The system states are the unit velocity vector and the angular velocity in a body-fixed coordinate system. The result can be viewed as a multi-variable controller for angle of attack, sideslip angle, and velocity vector roll rate. The backstepping design is performed on the rigid body dynamics described on vector form. The resulting controller achieves convergence to a desired state from almost all starting points. Guidelines are given for tuning the controller to affect the characteristics of the short period mode, the roll mode and the dutch roll mode. A coupled high angle of attack, high roll rate maneuver is simulated using a simplified aircraft model to illustrate the design.

In this study the first communication signal of life (i.e. the infant cry) will be analyzed. Authors show methods for the acoustic analysis of the infant cry and ways how to obtain the melody of crying. Previously several research groups had reported about the development of the infant cry, now authors are to present the development of the melody. The results are based on an infant cry database containing 2640 crying samples. If we know what kind of developmental chain we can expect from a healthy infant, we could check if an unhealthy infant followed this development or not. This study mostly deals with the classification of melody shapes, and the development of the fundamental frequency and the duration of the melodies.

To better identify the objects in remote sensing images, the multispectral images with high spectral resolution and low spatial resolution, and the panchromatic images with high spatial resolution and low spectral resolution need to be fused. Many fusion techniques are discussed in the recent years to obtain images with high spectral resolution and also high spatial resolution. In this paper an image fusion technique, based on integrating both the Intensity-Hue-Saturation (IHS) and the Discrete Wavelet Frame Transform (DWFT), is proposed for boosting the quality of remote sensing images. A panchromatic and multispectral image from Landsat-7(ETM+) satellite has been fused using this new approach. Experimental results show that the proposed technique improves the spectral and spatial qualities of the fused images. Moreover, when this technique is applied to noisy and de-noised remote sensing images it can preserve the quality of the fused images. Comparison analyses between different fusion techniques are also presented and show that the proposed technique outperforms the other techniques.

In this paper, an improved version of online continuation method controller for PWM systems is presented. The online continuation method controller solves the PWM-type deadbeat control problem numerically. By using this algorithm, iterations for solving the set of nonlinear equations always start from a good solution candidate and therefore it can be used online. The original continuation method is modified so that it is applicable to real systems. The validity of the proposed control method is demonstrated by a laboratory-scale flexible arm manipulator.

In this paper a parametric lineal model of heading is obtained, using a remote experimentation platform for marine vehicles. This platform has an in-scale fast-ferry physical model, TF-120 which is autonomous and has all the elements required to emulate a real vessel. The physical model is controlled remotely from a PC using Wi-Fi communications. The tests for the data acquisition with the platform for marine vehicles were carried out in the surroundings of the Bay of Santander. The parametric model identified is used to design a PID controller for heading autopilot and a simulation of this system is performed in Simulink.

StoLPaN, a pan-European consortium of companies, universities and user groups co-funded by the European Commission (EU), Information Society Technologies (IST) Programme aims to define open commercial and technical frameworks for the remote management of NFC-enabled (NFC: Near Field Communication) services on mobile devices. These frameworks will facilitate the deployment of NFC-enabled mobile applications across a wide range of vertical markets, regardless of the phone type and the nature of the services required. This paper introduces the application opportunities of the NFC technology, the business aspects of the NFC based service development and the technical infrastructure implementing the core of the NFC-enabled services.

In this work, different relaxations applicable to an MPC problem with binary control signals are compared. The relaxations considered are the QP relaxation, the standard SDP relaxation and an alternative equality constrained SDP relaxation. The relaxations are related theoretically, and both the tightness of the bounds and the computational complexities are compared in numerical experiments. The result is that for long prediction horizons, the equality constrained SDP relaxation proposed in this paper provides a good trade-off between the quality of the relaxation and the computational time.

We demonstrate the feasibility to make a temperature-independent strain sensor by measuring the bandwidth of the reflected light from the tapered fiber grating (TFG). This simple and low-cost sensor approach has a considerable potential, particularly application to strain sensing in the smart structures. The experimental results show that the method is suitable for distribution measurement, and it can restrain the influence of source fluctuation.
