Electrowetting, by applying boundary (line) stress and the macroscopic variation in the contact angle of the surface, operates according to an electric field in order to manipulate small volumes of liquids. Applied electrostatic field makes the conducting drop to move in the direction of the field. Electrowetting phenomenon simulation has been done by application of OpenFoam software in Linux operating system and interFoam solver, by using the method of the volume of fluid (VOF). Numerical modeling has been compared with experimental results has been confirmed, and then has been investigated through three dimensional modeling of the movement of fluid drop in microchannels under electrowetting phenomenon with channel's different heights. An increase in microchannel height at fixed volume of water drop causes the velocity of drop to increase. The movement of the drops under the electrowetting phenomenon stimulation in climbing up the inclined plane in microchannels has been investigated through variable angle toward the horizon. Increasing microchannels angle with the horizon surface decrease the drop ascending velocity.","PeriodicalId":168295,"journal":{"name":"2015 2nd International Conference on Knowledge-Based Engineering and Innovation (KBEI)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131810544","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}

A scaled model of a conventional medium sized bridge (length of 50 meters, height of 10 meters, and with 2 piers) was examined for the purpose of this study. This method includes installing two sensor nodes with the ability of measuring temperature and humidity on both side of the bridge deck. The data collected by the system including temperature and humidity values are received by a LABVIEW-based software to be analyzed and stored in a database. Proposed SHM monitoring system is equipped by a novel method of using data mining techniques on the database of climatic conditions of past few years related to the location of the bridge to predict the occurrence and severity of future damages. In addition, this system has several alarm levels which are based on analysis of bridge conditions with fuzzy inference method, so it can issue proactive and precise warnings and alarms in terms of place of occurrence and severity of possible damages in the bridge deck to ensure total productive (TPM) and proactive maintenance. Very low costs, increased efficiency of the bridge service, and reduced maintenance costs makes this SHM system a practical and applicable system. The data and results related to all mentioned subjects were thoroughly discussed and the accuracy and reliability of the SHM systems were evaluated. The results show that this system is qualified to be used as a SHM system in medium to large bridges.","PeriodicalId":168295,"journal":{"name":"2015 2nd International Conference on Knowledge-Based Engineering and Innovation (KBEI)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115098298","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}

Cloud computing provides resources and shared services through the internet. Services will be delivered through the data center. Cloud computing provides an interesting business proposal for information technology industry, which without any additional investment, customers are able to do heavy processing by devices such as a mobile phone that has the resources including the web browser to run. On the other hand, cloud computing has been subject to many security issues. When a client delivers his data to a cloud provider for saving, there is the possibility of data loss. From the perspective of customers, cloud computing security concerns are still in place, in particular issues related to data security and privacy protection. In this paper, the challenges and security issues in cloud computing are investigated from two perspectives being data security and privacy protection.","PeriodicalId":168295,"journal":{"name":"2015 2nd International Conference on Knowledge-Based Engineering and Innovation (KBEI)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128323138","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 effects of doping on optoelectronic properties of stannic oxide Nano layers were studied. Optical Reflectance measured in the wavelength range of 220-2500 nm by spectrophotometer. Other optical properties and optical band gaps were calculated using Kramers-Kronig relations on reflectivity curves. Electronic properties were calculated by full potential linearized augmented plane wave (FP-LAPW) method, within density functional theory (DFT). In this approach, the generalized gradient approximation (GGA) in the form of the LSDA functional was used for the exchange-correlation potential calculations. Band gap structures and density of states were calculated. Doping impurity changes optical properties of Tin dioxide layers. Metallic impurities, especially copper, decreases the band gap energy and increases conductivity of layers. Value of band gap calculated by DFT method for SnO2 compound obtained 1.2 eV. All results are in good agreement with each other.","PeriodicalId":168295,"journal":{"name":"2015 2nd International Conference on Knowledge-Based Engineering and Innovation (KBEI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130374795","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}
