Kamenjaković","doi":"10.1109/ICSENGT.2012.6339340","DOIUrl":"https://doi.org/10.1109/ICSENGT.2012.6339340","url":null,"abstract":"Lung segmentation is a powerful tool in medical imaging. It can be used in quantification of the lung disease progression, regression or stagnation, and change in the visual extent of disease over time is an important marker of response to therapy and a predictor of mortality. In this work we present a lung disease quantification method that we applied on the baseline and follow-up lung CT images. We proposed a new method for disease progression based on standard segmentation and registration techniques. The main scope of the work is to allow the radiologists to measure volumetric changes of the lungs and to calculate the proportion of the functional reduction of the healthy parenchyma area of the patients with the pleural disease, mesothelioma, and other lung diseases. The proposed method compares the segmented area that is not affected by the disease inside the parenchyma of the original and the registered follow-up exam of the same patient. By calculating the area of the healthy tissue in parenchyma, we can conclude that: if the area of healthy tissue is larger than on the follow-up scan, that the disease progressed, otherwise, the disease regressed. Preprocessing of the images was done by registration and transformation of the images by affine and non-rigid B-spline method. Region growing algorithm is used for segmentation and by comparison of segmented structures from those images resulted in determining the percentage of disease progression, which we compared to visual observers. Total number of 15 patients was taken for testing; total of 1584 CT slices. For the verification of the results, Dice similarity coefficient is used for segmentation accuracy, and in order to compare the results of quantification of the disease with the manual findings, 3D volume of the lungs is measured for each patient and compared with the clinical findings. Pearson correlation coefficient shows significant correlation of our method with visual observers and that our method has high diagnostic accuracy.","PeriodicalId":325365,"journal":{"name":"2012 International Conference on System Engineering and Technology (ICSET)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115774320","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 order to to develop a flexible simulator system with a long useful life, an abstraction needs to be introduced in the modeling and validation proses to separate it from the simulation engine itself. The aim is to develop an architecture that can separate the modeling proses of a simulation from the simulation engine that is being used. The language used to model the simulation is Modelica. The Modelica file is converted into the C programming language using tools provided from OpenModelica that is then integrated to the real-time simulator runtime developed in this thesis. This paper discusses the design and implementation of two different simulator architectures. These two architectures are the multi-threaded and non-threaded real-time simulator runtime. The conclusion of the testing and analysis done towards the two architectures is that the non-threaded architecture results in the most valid simulation producing simulation values closest to the real value and is able to fulfill the hard-real time requirements of the simulation.","PeriodicalId":325365,"journal":{"name":"2012 International Conference on System Engineering and Technology (ICSET)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125325832","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 this study multiple regression method was applied to explicate the contribution of environmental factors on air temperature element variation. Since air temperature data is in discrete points, therefore spatial interpolation analysis was used in producing continuous of this discrete data. In implementing spatial interpolation analysis, estimation error of T - T' data was used, where T is mean monthly air temperature and T' was estimated mean monthly mean air temperature from the developed multiple regression model. Analysis of cross validation was carried out to determine five measured of errors. Spatial interpolation analysis using main data of estimation error of T - T' produced reliable errors and consistent map for mean monthly mean air temperature element in Peninsular Malaysia.","PeriodicalId":325365,"journal":{"name":"2012 International Conference on System Engineering and Technology (ICSET)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130466071","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}

Besides the capability to predict the remaining time before the flood, this system can also detect three types of water level: early flood level, flood level and low tide level after the flood with a maximum water level detection of four meters. This system focused on an accurate measurement of the height of the water level and sending a warning message of the threshold height set before to the clients. For each of water level, the system will send three messages for each client number. The setting for client phone numbers and the water level can be programmed by sending the SMS that has been formatted in the system.

Although the direct digital panoramic radiography has been available, however film-based panoramic radiography is still used on the mostly dental clinic and laboratory in Indonesia. The quality of film-based image has significant limitation due to chemical processing and image enhancement cannot be done if required. Therefore, digitized film-based image to digital image was required to allow image enhancements in order to improve the interpretability quality of information in the image. Digitized film-based image is performed using a flatbed scanner on transmission and reflection mode. In this paper, the contrast quality of digital image that scanned using both mode is evaluated based on statistic image characteristic. The results showed that the quality of digitized image using transmission mode is better than using reflection mode. However, if direct digital imaging is used as a gold standard, image enhancement on digitized image is still required. Four methods, i.e. contrast stretching, HE, AHE, and CLAHE are used to attempt improve the quality digitized image. Evaluation of the preference image quality is performed based on objective criterion. The preference image quality for digitized panoramic image can be obtained by using image enhancement based on CLAHE-Rayleigh method, that indicated by the lowest value of mean, standard deviation, RMSE, and average difference and the higher value of NAE and SAE.","PeriodicalId":325365,"journal":{"name":"2012 International Conference on System Engineering and Technology (ICSET)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128876227","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}
