Because the electrode controller lowers the electrode according to the electrode consumption, it is possible to estimate the consumption by measuring the position of the electrode. However, due to the structure of the electrode and the electrode arm, it is difficult to measure the electrode position directly. Thus we measured the position of the mast which holds up the electrode arm. In order to determine when to replace the electrode, it is necessary to know the consumption of the electrode per operation. So, we calculated the representative value of the mast position for every operation. Then, we analyzed the changing trend of the representative values of the mast position to estimate the electrode consumption. Also, because the arc length increases about 1 cm when the arc voltage increases 10 V, we modified the representative values and estimated the electrode consumption. The results which were obtained from the analysis of the mast position are in good agreement with the real operation pattern.","PeriodicalId":6525,"journal":{"name":"2014 14th International Conference on Control, Automation and Systems (ICCAS 2014)","volume":"74 1","pages":"1384-1388"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82525384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The differential drive robot with four wheels is used as a mobile robot. The left wheels and right wheels are controlled separately. This allows robot to move forward or backward if we apply equal control signal for both sides' wheels, or to turn left or right if the control for left and right wheels is different. It is well-known that for differential drive robots the robot wheels angular velocity is slightly different even if the same control input is applied for left and right wheels. This lead to the arc trajectories of the robot instead of straight lines. To overcome this problem it's necessary to use some internal low-level controller for wheels angular velocity stabilization. In order to stabilize angular velocity we need estimation of its current value, which can be obtained using encoder data. The algorithm for angular velocity estimation and stabilization using rough encoder data is proposed. The simulation study and practical real-time implementation for a particular differential drive robot are presented using Matlab and Arduino environment.","PeriodicalId":6525,"journal":{"name":"2014 14th International Conference on Control, Automation and Systems (ICCAS 2014)","volume":"2019 1","pages":"1345-1350"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87792821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The popular fusion methods are intensity-hue-saturation (IHS)-based methods. However, the IHS-based methods have two major problems: (i) out-of-gamut due to transformation between red-green-blue (RGB) and IHS color systems and (ii) color distortion due to variation of saturation and intensity in image fusion. The proposed method studied on the relationship between intensity and saturation to preserve spectral information of the fusing THEOS images. Thus, we found a suitable color space, iHSL (improved hue-saturation-lightness) for pan-sharpening that can isolate the intensity or lightness component. The fusion method employs smooth filter-based intensity modulation technique to merge the spatial information from PAN with the intensity component from MS images. From the studied results, our method could preserve the spectral information better than the well-known IHS-based methods.","PeriodicalId":6525,"journal":{"name":"2014 14th International Conference on Control, Automation and Systems (ICCAS 2014)","volume":"16 1","pages":"686-691"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82422362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, neurocinematics has emerged as an interdisciplinary research field to understand how human brain reacts to films. So far, many studies attempted to find coherent responses among the subjects that are induced by a film. However, due to the sociocultural nature of cinema, a neurocinematic study may need to examine brain responses of a human population while they are watching a movie in the same space. In this study, we measured subjects' brain activity while they were watching a movie together at the same time. We investigated inter-subject correlations (ISCs) for each of five frequency bands: Delta (2~4Hz), Theta (4~8Hz), Alpha (8~13Hz), low Beta (13~18), and high Beta (18~23Hz). A non-parametric permutation method was used to test statistical significance. The results showed that the ISCs over all the frequency bands increased in several scenes, which were important for the stream in the plot of the movie. Our study demonstrated a plausibility of extracting coherent neural responses to films in a coextensive group of people.","PeriodicalId":6525,"journal":{"name":"2014 14th International Conference on Control, Automation and Systems (ICCAS 2014)","volume":"87 1","pages":"272-274"},"PeriodicalIF":0.0,"publicationDate":"2014-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85877870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our method comprises three steps. First, attentional points are detected using saliency maps (SMs). Subsequently, regions of interest (RoIs) are extracted using scale-invariant feature transform (SIFT). Finally, foreground regions are extracted as object regions using GrabCut. Using RoIs as teaching signals, our method achieved automatic segmentation of multiple objects without learning in advance. As experimentally obtained results obtained using PASCAL2011 dataset, attentional points were extracted correctly from 18 images for two objects and from 25 images for single objects. We obtained segmentation accuracies: 64.1%, precision; 62.1%, recall, and 57.4%, F-measure. Moreover, we applied our method to time-series images obtained using a mobile robot. Attentional points were extracted correctly for seven images for two objects and three images for single objects from ten images.
