This paper introduces a stereoscopy in Computed Tomography (CT), and two projection methods to create a stereoscopy. One is summing projection and the other is Maximum Intensity Projection (MIP). And then, comparison of stereoscopies using summing projection and MIP is presented. Numerical experiments from real CT data were performed for the comparison of the two techniques. Also Anaglyph 3D method is used to offer vivid 3D visualization effect to readers, and provides advantages and disadvantages of each method for conclusion.

This paper presents a 3D face reconstruction method from one side-view face images. In order to reconstruct 3D face, Structure from Motion (SfM) method, which has widely used to reconstruct 3D face, and bilateral symmetry of human face are used. In the experiments, the reconstructed 3D facial shape is quantitatively compared with the 3D facial shape obtained from a 3D scanner, and the results show that the proposed method is very useful to reconstruct an accurate 3D face when only one side-view face images are available.

This paper proposes a novel phase-noise (PN) reduction technique for high performance voltage-controlled oscillator (VCO) using a cross-coupled series LC resonator, rather than parallel LC resonator. While the series connected inductor and capacitor enhances the fundamental frequency swing at the LC connection node, it gives a cleaner spectral purity output and suppresses the overall noise at the drain node of the cross-coupled switching cell. The proposed technique is verified using a 65 nm CMOS process with the VCO operating at around 3.6 GHz frequency range. The phase noise of the VCO is -122.4 dBc/Hz, -125.0 dBc/Hz, and -136.7 dBc/Hz at 600 kHz, 800 kHz, and 3 MHz offset frequencies, respectively, which satisfy the stringent phase noise requirements such as GSM standards operating at 900-MHz, 1800-MHz and 1900-MHz band. The proposed VCO consumes 5.6 mW dc power from a 1-V supply.

In this paper, we propose a contrast enhancement method for OLED-TV. To enhance the contrast of image, we model a cost function that consists of brightness-term and contrast-term, and produce the contrast enhanced image by optimizing the cost function. The experimental results show that the proposed method exhibits considerable enhancements than histogram equalization method in terms of subjective image quality.

Behavior of metal-oxide junctions has been addressed as a memristive behavior after 2008. This behavior is not exactly matched with memristive behavior. Extension of memristive theory is needed to match device behavior. In this paper, we present a modeling technique to model these junctions and show how and why their behavior is not exactly memristive behavior. Simulation results verify the proposed model and fit the measurement results.

In this work, we investigated dependence of the spatial resolution in a microwave tomography system on significant parameters such as an operating frequency, dielectric properties of testing material, number of testing antennas, diameter of the circular array, and total amount of measured data. The spatial resolution was calculated in 3 to 6 GHz, based on original estimation method in microwave imaging.

An intensity-based fiber optic sensor (FOS) head, which consists of a rectangular pulse train shaped steel wire and an optical fiber, is proposed and applied to the measurement of FRP coupon strain. The measured data for FRP coupon strain are compared with those of a commercial FBG sensor and a strain gauge. The measured results show that the self-referencing intensity-based FOS with the proposed FOS head has good performance to measure the FRP coupon strain.

Most of the schedulers in the virtualization platforms provide throughput-oriented policy. However, such throughput-oriented policy has disadvantage in performance for multi-threaded applications which require synchronization among the threads or CPU-intensive programs. To solve this problem, we propose dynamic VCPU pinning mechanism that fixes VCPU to specific physical CPU considering the program characteristics. We demonstrate that the proposed method guarantees improved performance compared to the default VCPU assigning mechanism of credit scheduler in Xen hypervisor.
