It may be a good use for setting and changing components of game levels to analyze a FPS game player's goal-oriented action pattern. This article chooses test groups for novice and expert depending on game players' experience and verifies game actions seen through repetitive experiences. Furthermore, the actions which appear group by group are classified and coded so that the level of interaction with players according to game level may be ascertained with their change process. Accordingly, this study may be helpful to suggest a detailed modification method for correct expectation and game level in the situation of each game play.

This paper studies several channel estimation methods for LTE (Long Term Evolution) receivers in the FDD (Frequency-Division Duplexing) mode. The simulation results show that a 2-D 8-symbol linear estimation is sufficient for simulated channels. Higher complexity methods such as 2-D cubic convolution interpolation and piecewise cubic Hermite interpolating polynomial (PCHIP) do not significantly outperform the linear interpolation.

This paper presents a method for missing texture reconstruction via power spectrum-based sparse representation. We reconstruct missing areas based on minimizing the mean square error between power spectra (P-MSE). In our method, missing areas are reconstructed by embedding some known patches. Mathematically, we obtain the optimal linear combination of measurement patches by P-MSE minimization. The optimization can be solved as a combinatorial problem based on sparse representation. In this way, the optimal approximation which minimizes the P-MSE is obtained and we embed it in the missing area. Experimental results show effectiveness of our method for reconstructing texture images.

Side-channel Attack User Reference Architecture board SAKURA-W was developed to evaluate the physical security of IC cards equipped with cryptographic function. SAKURA-W works as a daughter board of SAKURA-G and uses hardware resources of SAKURA-G such as a controller FPGA and a USB interface. In this paper, we describe the basic functionality of SAKURA-W, and show its advantages over SASEBO-W, which is a conventional IC card evaluation board, through side-channel attack experiments using AES software on an 8-bit processor IC card ATMega163.

In a system manufacturing process that use screens, for exemple, TVs, computer monitors, or notebook, the inspection images is one of the most important quality tests. Due to increasing complexity of these systems, manual inspection became complex and slow. Thus, automatic inspection is an attractive alternative. In this paper, we present an automatic inspection system images using edge and line detection algorithms, rectangles recognition and image comparison metrics. The experiments, performed to 504 images (TVs, computer monitors, and notebook) demonstrate that the system has good performance.

A quad-band voltage-controlled oscillator (QBVCO) is proposed for multi-band satellite communication systems. The presented QBVCO is designed with a transformer feedback topology in a standard 180-nm CMOS technology. By improving the LC-tanks, the output signals of QBVCO exhibit four oscillation frequencies within the satellite communication bands. The lower bands, 15/20GHz, are generated by adopting dual-resonant LC resonators. The lower bands can be tuned by varying the control voltage of the varactors. The higher bands, 30/40GHz, are obtained by adding a push-push frequency doubler. The power consumption is 11.31mW at 1.5V supply voltage. The designed low power quad-band VCO has advantages of low phase noise and high output signal power without an extra negative supply voltage.

Image retargeting methods change the size of images to an arbitrary resolution while protecting visually important regions from distortion. Conventional retargeting methods fail to avoid distortion in the case where visually important regions are distributed all over the image. To solve this problem, we propose a novel image retargeting method that combines image warping with cropping and letterboxing operators. Letterboxing has the advantage of producing results without distortion or content loss although being unable to use the entire display area. Experimental results demonstrated the effectiveness of our method.

The embedded microcontroller is operated by the logic gates synchronized on the clock pulses. Severe electrical situations such as high voltage/frequency surge may cause malfunctioning of the clock source. Due to the broken clock, the clockless status of the system may enter into an abnormal state in driving several dangerous output. The glitch-clock pulse by abnormal clock generation causes the inversion of flip-flops status. In this paper, we propose an on-chip clock controller architecture to detect automatically clock failure and to switch the safe backup clock. The implemented edge detector (ED) unit identifies the abnormal low-frequency status of the clock source. The noise canceller (NC) using delay chain circuit of the clock pulse can detect the glitch status of the system clock. The simulation results show that the clock source damaged by external disturbance is successfully restored into safe clock status by the proposed on-chip glitch-free backup clock changer.

ThyssenKrupp Elevator has proposed a multi-directional multi-car elevator product, called MULTI. In this paper, we proposed a simplified mathematical model for multi-directional multi-car elevators. This model is based on Markon's S-ring, which is for single-car elevators. We developed a modeling tool based on the proposed model. In addition, we proposed zone scheduling for multi-directional multi-car elevators, and analyzed the proposed scheduling by applying them to the simulation.

Technical demands for extraction of significant components from spatial models are increasing as 3D sensors and their application technology has been developed and popularized. In this paper, we propose the 3D point cloud cluster analysis based on the principal component analysis(PCA) of normal-vectors. The distribution of normal vectors depends on a 3D surface shape within the local neighborhood. We discussed the PCA of the distribution of normal vectors to the point cloud. The results of the experiment show that our method could classify a local point cloud as a plane, a boundary and a vertex.
