This study was carried out to investigate the effect of ultrasonic wave scanning on the quality of fried chicken breast. The ultrasonic wave scanning time was 0(US-0), 3(US-3), 7(US-7) and 10(US-10) minutes, no respective comparison here. The moisture of raw breast was higher than that of flied chicken, while the crude protein, fat and ash of fried chicken were higher than those of raw breast(p<0.05). The moisture content was influenced by the ultrasonic waves scanning, but the crude protein, fat and ash were not. The $L^*$(lightness) and $b^*$(yellowness) values of fried chicken were higher than those of raw breast but the $a^*$(redness) value of raw breast was higher than that of fried chicken. The $L^*$ value was lowest in US-0, while the $a^*$ value was not significantly different and the $b^*$ value was lowest in US-7 among the fried chicken samples(p<0.05). The fried chicken was not influenced by the ultrasonic wave scanning, indicating that the longer scanning time increased the water holding capacity. The pH ranged from 6.54 to 6.93, and the calorie of fried was higher than that of raw breast, but was not influenced by the ultrasonic wave scanning time. The VBN content ranged from 8.73 to 12.3 mg%. The TBARS value of raw breast was lower than that of flied chicken and was not influenced by the ultrasonic wave scanning time. Total amino acid was highest in raw breast and lowest in US-3(p<0.05). The taste, texture and juiciness were superior with increasing scanning time, but flavor and Palatability were not significantly different among the fried chicken samples(p<0.05).

Minimization of processing time in two-photon stereolithography (TPS) has been one of important issues. Generally, a voxel scanning method (VSM) has been used in TPS because the method is very profitable for the stable fabrication irrespective of jittering and response time of scanning equipments such as a stage and a galvano-scanner. However, supplementary processing time due to the on/off control of a shutter for the generation of each voxel is required inevitably in VSM; by this reason, much processing time takes to fabricate largescale micropatterns and three-dimensional patterns. In this work, a continuous scanning method (CSM), generating patterns by movement of beam focus with a constant speed, is proposed for the improvements of scanning speed and precision in TPS. Some line patterns are fabricated by each scanning method to demonstrate the usefulness of CSM with viewpoints of scanning speed and precision.

This paper addresses the correlation between the change of file size and the scanning path build time by the slicing height of STL file. Though the study about STL file has been achieved quite actively scanning path build time using STL file is not investigated so much to be satisfied. The file size depends on the number of polygon created by the slicing height specified. And this number of polygons increases in a regular rate. The correlation between the number of polygons and the scanning path build time is examined and verified.

This paper is compared the build time of scanning path as to laminate height of the SLC and STL file. The STL file improve the surface roughness according to slicing height. But it have the fault spending long time to the creation of scanning path by being lower slicing height. So we proposed the SLC file to improve this fault. Therefore this paper showed to the build time of scanning path by the increase of peace using the jewellery model.

In this paper, we implemented the object scanning with nxtOSEK which is an open source platform. nxtOSEK consists of device driver of leJOS NXJ C/Assembly source code, TOPPERS/ATK(Automotive real time Kernel) and TOPPERS/JSP Real-Time Operating System source code that includes ARM7 specific porting part, and glue code make them work together. nxtOSEK can provide ANSI C by using GCC tool chain and C API and apply for real-time multi tasking features. We experimented the 3D scanning with ultra sonic and laser sensor which are made directly by laser module diode and experimented the measurement of scanning the object by knowing x, y, and z coordinates for every points that it scans. In this paper, the laser module is the dimension of $6{\times}10[mm]$ requiring 5volts/5[mW], and used the laser light of wavelength in the 650[nm] range. For detecting the object, we used the beacon detection algorithm and as the laser light swept the objects, the photodiode monitored the ambient light at interval of 10[ms] which is called a real time. We communicated the 3D scanning platform via bluetooth protocol with host platform and the results are displayed via DPlot graphic tool. And therefore we enhanced the functionality of the 3D scanner for identifying the image scanning with laser sensor modules compared to ultra sonic sensor.

This study has carried out scanning tests in order to figure out the features of scanning search by sex of space users, with the result of which the validity of data has been estimated. In this research, the scanning patterns were set up for verifying the typology of scanning paths and then the reason for determining scanning paths and the validity of estimation method were reviewed. Since the observation features depends on sex, the analysis of visual activities for acquiring any information in a space will reveal the intention and purpose of space users. The findings by analyzing the features of scanning pattern by sex which were found at the determination of scanning patterns can be defined as the followings. First, for estimating the process of space-information search, the movement distance at each point of continuative-observation data from the angle of eye-movement has been extracted, on the ground of which the fixation and movement of eye have been defined for the establishment of scanning-cut characteristics. Second, the scanning times were estimated for the extraction of effective observation data that would be used for comparative analysis, which showed that men had more data (3,398.2/64.4%) than women (2,998.2/55.6%). This enables the acknowledgment that the scanning cut of men was relatively less, which indicates that men will acquire more information on space than women in the process of observing any space. Third, men's scanning times (58.0 times/2.02 seconds) were less than those of women (71.9 times/1.39 seconds) while the scanning time of the former was longer than that of the latter, which shows the feature that it takes longer for men than women in scanning while the scanning times of the former is less than those of the latter. Fourth, the observation features can be determined that the combination of this result with the predominance character by sex for a general viewpoint to be employed indicates that while men employ mixed-scanning for observation activities to acquire space-information spending for longer time, women, by concentrated-scanning, focus on a single point for shorter time or stay at one location for a considerably long time for space-information acquirement.

An electronic initiation system that can support various types of field blasting works has been developed and put into practice. The newly developed equipment called Hanwha Electronic Blasting System (HEBS) II has three basic operation modes of scanning, logging, and tagging, among which the blaster can choose the most suitable one for the specific site conditions. In the present study, the work efficiency of the system in the scanning, logging and tagging modes was compared with that of the previous non-electric detonator. The results were estimated based on the aspects of the ground vibration, fragmentation, and digging time. It was found that the ground vibration, fragmentation, and digging time of the new system were decreased by about 45%, 31%, and 13%, respectively, with respect to the previous system. This result confirms that the new system is very efficient in the scanning, logging and tagging modes under the field conditions.

In Bayesian multi-target tracking, the Poisson multi-Bernoulli mixture (PMBM) filter is a state-of-the-art filter based on the methodology of random finite set which is a conjugate prior composed of Poisson point process (PPP) and multi-Bernoulli mixture (MBM). In order to improve the random finite set-based filter utilized in multi-target tracking of sensor scanning, this paper introduces the Poisson multi-Bernoulli mixture filter into time-matching Bayesian filtering framework and derive a tractable and principled method, namely: the time-matching Poisson multi-Bernoulli mixture (TM-PMBM) filter. We also provide the Gaussian mixture implementation of the TM-PMBM filter for linear-Gaussian dynamic and measurement models. Subsequently, we compare the performance of the TM-PMBM filter with other RFS filters based on time-matching method with different birth models under directional continuous scanning and out-of-order discontinuous scanning. The results of simulation demonstrate that the proposed filter not only can effectively reduce the influence of sampling time diversity, but also improve the estimated accuracy of target state along with cardinality.

This paper presents studies on the creation time of scanning path using rapid prototype device. In the case of Jewellery, it needs to take time too much at the whole process of rapid prototype in accordance with heigh of the multi-layered. When increases the number of polygon by heigh of the Multi-layered, it has proper influence on the creation time of scanning path. Therefore, we can get the spending time and the number of polygon for the creation during increase the heigh of the multi-layered. These values are showed by the quantitative. We try to analyze relation between these and heigh of the multi-layered.

This paper is about a real-time automatic face recognition system based on one-shot panoramic scanning. It detects multiple faces in real time through a single panoramic scanning process and recognizes pre-registered faces. Instead of recognizing multiple faces within a single panoramic image, multiple faces are recognized using multiple images obtained in the scanning process. This reduces the panorama image creation time and stitching error, and at the same time can improve the face recognition performance by using the accumulated information of multiple images. It is expected that it can be used in various applications such as a multi-person smart attendance system with only a simple image acquisition device.
