By scanning the beams with their direction information embedded in the received waveform, the microphone yields a 2D map of amplitude according to the beam direction. Because the maximum amplitude in the map corresponds to the beam direction, multiple beams with different root position offers three-dimensional microphone localization. By numerical examples, the validity of the method is assessed and the advantages and drawbacks of the method are accordingly discussed.","PeriodicalId":147772,"journal":{"name":"2019 58th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117067319","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}

Humans have an ability to analyze the context of visual scene and focus their attention to salient regions in the crowd scene. In this work, we propose a novel convolutional neural network based method for saliency prediction. Unlike classical works on crowd scene using hand-crafted face features, our model extracts deep features using convolutional layers from image classification model and learns the global context using large receptive convolutional layers. Self-attention mechanism is applied to detect the dependency between elements of feature maps. This model overperformed state-of-the-art methods on the saliency in human crowd Eyecrowd dataset.","PeriodicalId":147772,"journal":{"name":"2019 58th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"166 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121608513","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}

In the market, most wheelchairs that can climb stairs use a crawler-type or double planetary gears' wheel. But the crawler has the disadvantages of being bulky and has big friction on the ground and double planetary gears' wheel will cause big shake while climbing stairs. Rocker-bogie is also a mechanism can step over high obstacles but cannot climb stairs. To climb stairs smoothly and safely, we designed a wheelchair that based on the three mechanisms with advantages of all of them. With linkage mechanisms, the wheelchair can also adjust the location of the center of gravity (COG) of the user for safer climbing. Additionally, the linkage mechanism can also assist the user to stand up, which is more helpful for the user of the wheelchair. It is composed of four-linkage and parallelogram mechanisms. To assist the user to stand up with the normal posture of a healthy elderly, three parameters were taken into account in the design of chair part: trajectory of COG, the change of the upper body angle and the trajectory of the hip joint of the user while standing up. From the simulation results, the torque of the knee and ankle joint of the user being assisted to stand up decreased much. From theoretical calculations and experiments of the scaled models, different new mechanisms were compared and the one that was able to climb stairs most smoothly and stably was chosen. The effectiveness of the new mechanism was confirmed.","PeriodicalId":147772,"journal":{"name":"2019 58th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133866813","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 identification problem of EIV models with unknown noise variances has been studied extensively and several methods have been proposed. To be further developed in terms of estimation accuracy, the bias compensated weighted least squares (BCWLS) method with only requirement of input noise variance estimate has been proposed by using the biased weighted least squares estimate. However, the recursive form for the standard least squares estimate cannot be applied to recursively compute the BCWLS estimate because the weight matrix is not diagonal. To recursively compute the BCWLS estimate, the recursive forms for the WLS estimate and the input noise variance estimate are derived when the biased WLS estimate is two-stage least squares type estimate. The results of a simulated example indicate that the proposed recursive algorithm provides good results.","PeriodicalId":147772,"journal":{"name":"2019 58th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125791434","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 model of Single Shot Multibox Detector is used for detecting and recognizing the ancient characters. This paper only focuses on the recognition of Oracle Bone Inscriptions which is the one of the oldest and most mysterious ancient characters, used about 3000 years ago in china. The experimental results show that Precision achieves and Recall achieves 0.86 and 0.97, respectively, and prove the effectiveness of Single Shot Multibox Detector in ancient characters recognition. By analyzing the experimental results, we found that in the case of heavy blurred image or tilted characters, the Single Shot Multibox Detector can not achieve a exciting results. Hence, we apply the pre-processing of binarization, changing brightness and contrast, and rotation in the test images, and then achieve accuracy improvement of recognition by using pre-processed images.","PeriodicalId":147772,"journal":{"name":"2019 58th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117182887","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}
