Mathematical modeling and simulation are applied to examine the influence of the different physical and electrochemical phenomena occurring in the structure of the fuel cell during operation. Such simulation programs take a very long time (of the order of days or even weeks) to run, especially when accurate results are called for. To achieve accurate results and more insight, we need even more complex models (twoand threedimensional models). In this paper, we present techniques for the parallel simulation of a mathematical model of direct methanol fuel cells (DMFC). In particular, we employ a paradigm called LessTalk. LessTalk is a general technique that can be employed to reduce communications in parallel computations. Using LessTalk, we have achieved almost linear speedup in simulating the DMFC model. The results were validated against measurements available from the Connecticut Global Fuel Cell Center (CGFCC).

One of drowsiness and fatigue visual indicators is excessive yawning. In this paper, a non-optical sensor presented as a car dashcam that is used to record driving scenarios and imitates real-life driving situations such as being distracted or talking to a passenger next to the driver. We built a deep CNN model as the classifier to classify each frame as a yawning or nonyawning driver. We can classify the drivers' fatigue into three levels, alert, early fatigue and fatigue based on the judgement of the number of yawns. Alert level means when the driver is not yawning, while, early fatigue is when the driver yawns once in a minute. Fatigued is when the driver yawns more than once in a minute. An overall decision is made by analyzing the source score and the condition of the driver's fatigue state. The robustness of the proposed method was tested under various illumination contexts and a variety of head motion modes. Experiments are conducted using YAWDD dataset that contains 322 subjects to show that our model presents a promising framework to accurately detect drowsiness level in a less complex way.

However, it suffers from a ubiquitous problem of data imperfection. Based on this situation, several models have been proposed to solve those problems. These models could improve the situation caused by the imperfect data, but they lack the ability to handle the accuracy issue that exists in the data. Therefore, an accuracy model is proposed here for relational databases. The theory of probability is utilized to help define accuracy in databases, and also relational algebra is extended for the use with accuracy model. Some implementation issues are also discussed.","PeriodicalId":264035,"journal":{"name":"International Conference on Computers and Their Applications","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128395783","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}

Several researchers have shown that reducing the dimensions is very important in analyzing extensive graph data. They applied a variety of dimensionality reduction strategies, including linear methods or nonlinear methods. However, it is still not clear to what extent the information is lost or preserved when these techniques are applied to reduce the dimensions of large networks. In this study, we measured the utility of graph dimensionality reduction, and we proved when using the very recently suggested method, which is HDR to reduce dimensional for graph, the utility loss will be small compared with popular linear techniques, such as PCA, LDA, FA, and MDS. We measured the utility based on three essential network metrics: Average Clustering Coefficient (ACC), Average Path Length (APL), and Average Betweenness (ABW). The results showed that HDR achieved a lower rate of utility loss compared to other dimensionality reduction methods. We performed our experiments on the three undirected and unweighted graph datasets.","PeriodicalId":264035,"journal":{"name":"International Conference on Computers and Their Applications","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121123582","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}
