The accuracy of de-embedding techniques depending on de-embedding layout patterns has been verified by experiment up to 110 GHz for CMOS circuits. The accuracy of the measured characteristics is affected significantly by the de-embedding procedure, which has been done for the raw measurement data. The de-embedding patterns and some transmission lines (TL) as test device were designed and fabricated using 40 nm CMOS process. From the experiment results, it was confirmed that each characteristic of the TL, such as propagation constant and characteristic impedance, has a different suitable de-embedding pattern to set a reference plane at a different desired position.

Aiming to develop a strategy for the conservation of freshwaterdolphins inhabiting Asian areas, a new international collaborating project forreal time networking of freshwaterdolphin's observatories in Asian waters using passive acoustic monitoring system between Japanese team, Indian team and Indonesian team has been started since April 2010. The project networks the data from the observatories that consist of the existing observatories for the Ganges riverdolphins in Narora (India), the Irrawaddy dolphins in Chilika lake (India) and a newly developed observatory for the Irrawaddy dolphins in Mahakam river (Indonesia). The systems are designed by the following common concept: dolphin's 3-d location data and their habitat environment data such as water quality are transferred through the host server anywhere in the world by internet and monitored by a PC with appropriate viewer program. In addition, the database forrecordeddata from three observatories has been created fordata sharing and further analysis. The initial experiments in Borneo were made from 17-22 december 2011 and the recordeddata was uploaded to the database.

We have developed a new LCd controller incorporating a Compression Feedforwarddriving, which will be second generation Feedforwarddriving. In spite of having only one SdrAM, this LCd controller can offer nearly ideal performance, improving the response time through utilizing image compression technology to reduce the frame memory requirement.

CPT has successfully developed the 4.8′ WVGA 3ddisplay viewed without wearing glasses while can show full-resolution and switching 2d/3ddisplay. Three-dimensional display in the time division is needed for faster frame rates and faster liquid crystal response time. When liquid crystal response time can not demand the LCd fast frame rates, it will produce crosstalk. Therefore, we propose a simple test of picture and methods.

Thin film barium strontium titanate, Ba1−xSrxTiO3 (BST), has been deposited on Pt bottom electrodes using metal-organic decomposition (MOd). Optimization of BST electric properties, including capacitance density and leakage current, can be achieved by altering the chemical and microstructural attribute of the films. dielectric properties of BST are strongly dependent on processing temperature, film thickness, composition, and microstructure, which are closely correlated with each other. Nucleation temperatures of BST range from 580°C – 650°C depending on film thicknesses. The chemical composition giving the highest dielectric constant is explained in terms of microstructure; capacitance increases with increasing grain size for the BST films in this study. Capacitance density of 50 fF/μm2 and leakage current density < 100 nA/cm2 at 1.6 V can be achieved by optimizing BST materials properties. In addition, leakage conduction through the Pt/BST/Pt capacitor is shown to consist of polarization current resulting from debye relaxation and true leakage current attributed to Schottky electron emission.

In this paper, microencapsulated phase change materials(MicroPCMs) were prepared using polystyrene(PS) as shell materials to coat n-Octadecane by emulsion polymerization. Sodium dodecyl sulphate(SdS) was used as Emulsifier. The effect of amount and species of comonomer, proportion of monomer/n-Octadecane、addition of cross linking agent to the process were discussed in detail. Scanning electron Microscopy(SEM), dTA-TGA anddifferential scanning calorimeter(dSC) were used to analyze the characterization of the MicroPCMs. The results showed that MicroPCMs was prepared successfully using copolymer of styrene and methyl methacrylate to coat n-Octadecane. When the amount of comonomer was at 33.3wt% and the proportion of monomer/n-Octadecane was 1:1, the characteristic of MicroPCMs was better. The microcapsules with smooth surface were about 5μm in diameter and the size distribution of microcapsules was even. The addition of dVB was disadvantage to the forming of microcapsules. The ΔH of MicroPCMs prepared in optimal process was about 137.5J/g. MicroPCMs can be used to prepare functional phase conversion thermo regulated fiber and functional finishing of fabric.
