The multi-period repetitive control system is a type of servomechanism for a periodic reference input. When multi-period repetitive control design methods are applied to real systems, the influence of uncertainties in the plant must be considered. In some cases, uncertainties in the plant make the multi-period repetitive control system unstable, even though the controller was designed to stabilize the nominal plant. Recently, the parameterization of all robust stabilizing multi-period repetitive controllers for multiple-input/multiple-output plants was obtained by Chen et al. However, using their method, it is complex to specify the low-pass filter in the internal model for the periodic reference input of which the role is to specify the input-output frequency characteristic. Because, the low-pass filter is related to four free parameters in the parameterization proposed by Chen et al. This paper proposes the parameterization of all robust stabilizing multi-period repetitive controllers for multiple-input/multiple-output plants with specified input-output frequency characteristic such that the input-output frequency characteristic can be specified beforehand.

Thin film sputtering on the desired substrate is one of an industrial application that needs to split atoms of sputter gas, such as Argon (Ar), to ions and electrons. This can be done by plasma driven circuit that delivers a high frequency sinusoidal current waveform to the sputtering machine. For the reason of high efficiency (more than 70% at 100 - 500 W) with high frequency sinusoidal current waveform, this paper presents an application of half-bridge class D series-parallel-resonant inverter for plasma-driven circuit. In order that the inverter can operate at zero voltage turn-on switches (ZVS), the resonant frequency (fo) of resonant tank is set below switching frequency (f). However, the vacuumed chamber of sputtering system has a complicated physical structure, so that a simply load model is used together with an ideal model of matching impedance transformer. The design concept is realized by 373 W of prototype with 80.7% of efficiency at 100 kHz switching frequency. Under environment of Argon gas, the experimental results verify that the prototype can sputter thin film of material target; which here is Titanium, on glass slide.

Conventional color image watermarking usually causes sever color and texture distortions when applied to high dynamic range images. In this paper, we thus propose a new color image watermarking method for high dynamic range image. Based on modification of the blue component in the detail layer of host image, some color and texture distortions can be significantly reduced. Set of experiments are carried out to verify our concept. The experimental results show an efficiency of the proposed method, in both higher quality of watermarked image and more robustness of embedded watermark against various types of attack, compared to the previous work [7].

This paper presents a wideband circular polarization antenna with tuning rectangular slot fed by coplanar waveguide (CPW). The proposed antenna has been designed to enhance widely the impedance bandwidth. Circular polarization is achieved by the slots around two opposite corners of the square slot. A small tuning stub is placed at the end of strip on CPW to obtain a good impedance matching. The proposed antenna attains an over-lapped bandwidth (axial ratio ≤ 3 dB and return loss ≤ 10 dB) of 17.39% (2.31–2.75 GHz) in measurement.

The influence of annealing treatment on structure properties of the indium tin oxide (ITO) films has been investigated. ITO films annealed to improve quality films were prepared by RF sputtering system at 100 W. The samples at different thicknesses were deposited on non-heated glass slide at room temperature. Annealing temperature in pure nitrogen atmosphere for 15 minutes was varied at 200, 300, 400 and 500°C, respectively. Effect of nitrogen flow on properties of ITO films has been studied. It has been observed that the energy dispersive x-ray (EDX) analysis showed O, Sn and In content in the ITO films. The effect of thermal annealing on roughness of the surface and on the structure of deposited film was observed by scanning electron microscopy (SEM) that grain size increases, the transmission of ITO thin films increases after annealing by UV-vis spectroscopy and the resistivity decreases after annealed from 9 to 1 ohm-cm.

Several indoor chemical contaminants such as CO and NO2 are highly toxic. Inhalation of CO or NO2 as low as ppm level may cause respiratory distress or failure. Therefore, detection of indoor air is very important in the industrial, medical, and environmental applications. In this paper, a new electronic nose (E-nose) architecture has been proposed for the real-time quantification and qualification of indoor air contaminations. The metal oxide TGS gas sensors were used as the sensing part. The principal component analysis (PCA) method and a set of mathematical model were employed in data analysis. By combining with the proposed mathematical model, this E-nose can estimate the amount of CO gas contaminations in air at ppm levels. Moreover, the PCA results can clearly show a classification between two different rooms.

Ubiquitous network is really one of remarkable trends of next generation information and communication technologies. However, the rapid increase of ubiquitous technologies has given rise to serious concerns about power dissipation and security issues which are getting worse, especially in the case of ad-hoc network because it is resource constrained. The authors have so far developed a ubiquitous processor named HCgorilla. This has unified basic aspects of PC processors, mobile processors, Java CPUs, cryptography processors, etc. The unification of these has been effective to achieve power consciousness and secureness for ubiquitous environment. Considering the increased demand for Green IT in recent years, the target of this study is the further improvement of HCgorilla chips with particular emphasis on low resource and secure implementations. The improved HCgorilla is implemented in a CMOS standard cell chip. Specific features of the HCgorilla chip are also described.

Evacuation simulator is an important tool which can create solution for emergency circumstance. Evacuation simulation becomes more realistic but it has to tradeoff between memory consumption and processing time. This paper proposes a method to predict evacuation time by converting floor layout to building block structure and predicts evacuation time of each building block. Then we can use the predicted result to calculate total evacuation time of scenario without re-simulate whole scenario. The proposed method can reduce the processing time and memory usage which make user get total evacuation time faster but still maintain correctness of result.

In this recent year, an image reconstruction based on small number of measured components is a useful application of Compressive Sensing (CS). In the field of CS, SL0 algorithm is known as one of the fastest and most accurate algorithm but this algorithm is very unreliable under the noisy environment. Unfortunately, there are no researches for solving this SL0 ill-posed condition therefore the SL0 algorithm can only apply on limited applications. To solve the SL0 ill-posed condition, this paper proposes a novel regularization technique for the image reconstruction algorithm based on the SL0 technique to estimate the reconstructed image in the frequency domain for CS implementations. The novel frequency domain Tikhonov regularization technique is cooperated in this SL0 algorithm for reducing and constraining the space of possible reconstructed image due to this ill-posed problem. By cooperating the proposed regularization technique, the solution of the image reconstruction algorithm has better performance and more stable under the noise which contaminates the properties of the image. The experimental result shows that the proposed Tikhonov regularization technique can be well effectively applied on noisy images such as Lena, Resolution_Chat and Cameraman under both Gaussian and Non-Gaussian noise models (such as AWGN, Poisson noise, Salt & Pepper noise and Speckle noise) at different noise powers.

Energy consumption has become a main issue in many organizations. Techniques for energy conservation have been developed, not only to decrease the energy cost, but also to help saving our environment. This paper presents a concept of power consumption monitoring using wireless sensor network. We design and implement a platform for current detection system which can measure electric current usage of electronic devices or equipments in a data center. We apply a wireless sensor network with Zigbee Technology between the current detection sensor node and the base station. In our experiments, the current detection sensor can measure current usage with high accuracy compared with standard clamp meter. Current usage information will be transmitted from the current sensor node to the base station and then forwarded from the base station to the database server for further analysis and strategic planning.
