We present a perceptual omnidirectional image quality assessment (IQA) study in this paper since it is extremely important to provide a good quality of experience under the VR environment. We first establish an omnidirectional IQA (OIQA) database, which includes 16 source images and 320 distorted images degraded by 4 commonly encountered distortion types, namely JPEG compression, JPEG2000 compression, Gaussian blur and Gaussian noise. Then a subjective quality evaluation study is conducted on the OIQA database in the VR environment. Considering that humans can only see a part of the scene at one movement in the VR environment, visual attention becomes extremely important. Thus we also track head and eye movement data during the quality rating experiments. The original and distorted omnidirectional images, subjective quality ratings, and the head and eye movement data together constitute the OIQA database. State-of-the-art full-reference (FR) IQA measures are tested on the OIQA database, and some new observations different from traditional IQA are made. The OIQA database will be released to facilitate further research.","PeriodicalId":6569,"journal":{"name":"2018 IEEE International Symposium on Circuits and Systems (ISCAS)","volume":"18 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77995374","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 high voltage improves the number of membrane pores, however, it might kill the cells. Electroporation is achieved using a microelectrode placed in a microfluidic device. This paper focuses on the improvement of the electroporation of a cell based on levitation dielectrophoresis and an electrorotation force. Then, the change of the conductivity is detected at both the frequency and time domain, i.e., individual cells are trapped due to the effect of levitation and electrorotation force, and then the variation in the conductivity is detected. We use frequency and time domain spectroscopy to measure the conductivity of the white blood cell, i.e., B-cell, T-cell and leukemia K365. In this paper, we review studies of conductivity separation in a microfluidic device based on a 2-D electrode system. Also, a comparison between the conductivity of leukemia k365, B-cell, and T-cell due to the drag and electrorotaional forces are presented and discussed.","PeriodicalId":6569,"journal":{"name":"2018 IEEE International Symposium on Circuits and Systems (ISCAS)","volume":"25 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74072450","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 proposed sensor utilizes nonlinear adaptive biasing to maintain consistent bandwidth and phase margin in the sensor's control loop across a wide range of load currents, leading to high sensing accuracy independent of the load. Moreover, auxiliary sensing FETs are proposed to eliminate sharp transitions in the sensed high-side and low-side currents as the buck converter switches between the ON and OFF phases. Eliminating these sharp transitions enables the bandwidths of the current sensor's control loop and the nonlinear adaptive biasing generator to be greatly relaxed without compromising sensing accuracy, leading to lower power consumption. The proposed sensor is implemented as part of a 2-MHz buck converter in a 0.5-μm standard CMOS technology. Simulation results of the proposed sensor show a 10% reduction in current sensing error at light loads (∼50mA) and 40 degrees of improvement in the phase margin of the sensor's control loop at heavy loads (∼5A), compared to conventional sense-FET-based current sensors. Furthermore, the variation in the unity gain frequency (UGF) of the proposed sensor's control loop across the entire load range is 4.5 times lower than that of conventional designs.","PeriodicalId":6569,"journal":{"name":"2018 IEEE International Symposium on Circuits and Systems (ISCAS)","volume":"10 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85527571","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}
