  • The location template matching(LTM) method is a technique of identifying an impact location on a structure, and requires a certain measure of similarity between two time signals. In general, the correlation coefficient is widely used as the measure of similarity, while the group delay based method is recently proposed to improve the accuracy of the impact localization. Another possible measure is the frequency response assurance criterion(FRAC), though this has not been applied yet. In this paper, these three different measures of similarity are examined comparatively by using experimental data in order to understand the properties of these measures of similarity. The comparative study shows that the correlation coefficient and the FRAC give almost the same information while the group delay based method gives the shape oriented information that is best suitable for the location template matching method.

  • Porous layered carbon was prepared by interlayer pyrolysis of pyrolysis fuel oil (PFO) using magadiite template and successive dissolution of template. Particle morphology was plate type with d-spacing of approximately 0.7 nm and it had constant interlayer space. Specific surface area was $147{\sim}385m^2/g$ depending upon template type, mixing ratios and pyrolysis time.

  • After detecting the edge which is applying the morphological operators to the hybrid FCNN, we could analyze and compare. The hybrid FCNN is completely removed to the noise in the image, and worked in order to obtain the result image which is closest to the original image. Also, the morphological operator is applied to the image as the method in order to detect more good the edge than the conventional edge. FCNN which is the pipeline type is completely suitable to detecting the image processing as well as the hardware size. In this paper. we would make the structure elements of the morphological operator the variable template and the static template, and compare with the edge enhancement of two images. After being the result which is applying the variable template morphological operator and the static template morphological operator to the image, we could know that the edge images applying the variable template is superior in a edge enhancement side.

  • We report the phase transition temperatures of the $PbZrO_3$ perovskite nanotubes made by sol-gel template synthesis. The lead zirconate($PbZrO{_3}$) nanotubes were prepared with a chelate sol-gel of zirconium tetrabutoxide($Zr(OBu){_4}$) and leadacetate($Pb(OAc){_2}-3H_2O$). $Whatman^(r)$ anodisc membranes, with a 200nm pore size, served as the template. After removing the template in the 6M-NaOH solution, the $PbZrO{_3}$ nanotubes so far have shown an anomalous transition temperature, $123.6^{\circ}C$ as measured by DSC with a small particle size, 15.4nm determined by X-ray analysis with the aid of Scherrer's equation.

  • To generate the template of a detected object and to track the overlapped object and the object covered by other objects correctly are important research problems in visual surveillance. The frame difference is not capable of generating the template of slowly moving object. To get around the drawback of the conventional frame difference, we propose a new algorithm for generating a template using adaptive 3-frame difference.

  • Zinc oxide micro rods were fabricated using as chemical bath deposition ok photolithography. Vertically aligned Zinc Oxide rod array as grown by chemical bath deposition method on Zinc Oxide template layer. The ZnO template layer was deposited on glass and the pattering was made by standard photolithography technique. The selective growth of ZnO micro rods were achieved with the masked ZnO template layer substrate. The fabricated ZnO micro rods were found to be single crystalline and have grown along hexagonal c-axis direction of (0002) which is same as the preferred growth orientation of ZnO template layer. The ZnO micro-rod array structure was implemented as a window layer in Cu(InGa)Se2 solar cell and its effect on photovoltaic efficiency was examined.

  • Some treatment methods have been proposed for patients with chronic closed lock of temporomandibular joint. We report a conservative treatment for patients who had chronic closed lock of temporomandibular joint and who did not want surgical treatment. Two patients who had been treated in the Template clinic, Soonchunhyang University Bucheon Hospital, are the subjects of this report. The subjects had chronic closed lock symptom for over 3 months after an onset of locking; conventional therapies had no effect. The subjects were treated by making them wear a Template appliance while sleeping and exercise for 10 hours a day. After periodic follow-up, significant improvement was observed for Template treatment in terms of the maximal mouth opening range. When conventional therapy is expected to be ineffective, The Template appliance can be used as conservative treatment for temporomandibular disorders patients with chronic closed lock of temporomandibular joint.

  • The utilization of System Design Data(SDD) based upon Model Based Systems Engineering(MBSE) process is as important as the building of them. This paper describes the development and the utilization of a report template which can extract and modify data we need from SDD. A report template is defined as a set of elements in the Reporting Facility and is created by placing a sequence of Reporting elements onto a Behavior Diagram-like structure called a ReportNet. We focus on the development of a report template to secure and validate requirements traceability.
