We calibrated the temperature using the gel-tool in YCrCb (Y: brightness, Cr: red color difference, Cb: blue color difference) color space. Y and Cr decrease monotonously with increasing temperature, whereas and Cb do not vary monotonically with temperature change. Cr is suitable for long-time temperature measurement because the Cr is robust against brightness fluctuations. This method has a sensitivity of −1.3 %/K and an accuracy of α0.3 K.

Then, non-equilibrium W/O droplets, composed of water containing hydrogel molecules as the disperse phase and a water-soluble organic solvent as the continuous phase, were used to prepare extremely small hydrogel Ca-alginate hydrogel beads (Φ = ∼10 µm). As an application, high-density cell cultivation (∼1×108 cells/mL) in the yarn-ball-shape hydrogel beads was demonstrated.

Whereas, manipulating deformable linear objects (DLOs) such as hoses, wires, cables is common in daily life and many domains such as manufacture, medical surgery and so on. The DLOs are more challengeable to handle, as the uncertainty results from oscillation at the end of DLOs may cause failure in the operation. During manipulating DLOs, especially moving them rapidly, the dynamic characteristics can not be neglected. In this paper, based on the dynamic model of DLOs, we illustrate a skill-based manipulating strategy for eliminating the vibration at the end of DLOs. The method is position-based and inspired from human manipulation skills. From our life experience, when people manipulate DLOs by hand, the oscillation will be significantly reduced if we suddenly lift it up with a certain acceleration. Based on the idea and dynamic model of DLOs, the control strategy by using fuzzy and PI controller is illustrated. The effectiveness of the proposed strategy is confirmed by numerical simulation results. The simulation results show that the proposed method can damp the vibration effectively.","PeriodicalId":286457,"journal":{"name":"2011 International Symposium on Micro-NanoMechatronics and Human Science","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129521380","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}

Hepatic function increased when HC were cultured within endothelial cells (EC) and hepatic stellate cells (HSC). Nitric oxide (NO) also increased hepatic function. However no study has described the effects of media flow load on a co-culture model of HC, HSC and EC. Furthermore there was no research on NO in co-culture model. Therefore, we developed co-culture models that include three of these cell types, and assayed their hepatic functions under flow. We also measured the NO concentration in each models. All models under load of flow exhibited high hepatic function than in static culture. Under load of flow, HC+HSC model and HC+HSC+EC model showed the highest hepatic function. In almost models NO concentration exhibited the same tendency to increase along with hepatic function. We suggested co-culture and flow influenced hepatic function, and NO related to the improvement of hepatic function. Furthermore, we thought HSC caused other elements of the improvement.","PeriodicalId":286457,"journal":{"name":"2011 International Symposium on Micro-NanoMechatronics and Human Science","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130721436","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}

For this purpose, a simple new model is proposed to describe the process of mating connectors, within which the distance between the connector and deformable PCB is the observable variable.
