Ultrasound is a recommended modality for diagnosing breast cancer through ultrasound images. However, misdiagnosis might still occurs which is caused by human factors. Margin of breast nodule is one of the malignancy characteristics based on BIRADS. This research proposes a computer aided diagnosis (CADx)-based method for classifying breast nodules in ultrasound images based on margin characteristics. In practice, CADx is used as a second opinion in interpreting ultrasound images in order to obtain more accurate diagnosis results. The proposed approach consists of adaptive median filter for marker removal, pre-processing with normalisation and speckle reduction anisotropic diffusion (SRAD) filter followed by neutrosophic and watershed methods for segmentation process, features extraction and feature selection. A total of ten selected features including of texture, geometry and margin sharpness features are then classified by using multi-layer perceptron (MLP). This study uses 102 breast ultrasound nodule images with 57 non-circumscribed and 45 circumscribed margins. The performance of proposed approach achieves the accuracy of 95.10%, sensitivity of 93.33%, specificity of 96.49%, PPV of 95.45%, NPV of 94.83%, Kappa of 0.9004 and area under curve (AUC) of 0.989. These promising results indicate that the proposed approach successfully classifies breast nodule based on margin characteristics has a potential for assisting the radiologists in interpreting breast ultrasound images.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122353416","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 2015, this country succeeded to produce 32.5 million tons of palm oil, and used 26.4 million of it to export to other countries. The quality of Indonesia's palm oil production has become the reason why Indonesia becomes the famous exporter in a global market. For this reason, many Indonesian palm oil companies are trying to improve their quality through smart farming. One of the ways to improve is by using technology such as Internet of Things (IoT). In order to have the actual and real-time condition of the land, using the IoT concept by connecting some sensors. A previous research has accomplished to create some Application Programming Interfaces (API), which can be used to support the use of technology. However, these APIs have not been integrated to a User Interface (UI), as it can only be used by developers or programmers. These APIs have not been able to be used as a monitoring information system for palm oil plantation, which can be understood by the employees. Based on those problems, this research attempts to develop a monitoring information system, which will be integrated with the APIs from the previous research by using the Progressive Web App (PWA) approach. So, this monitoring information system can be accessed by the employees, either by using smartphone or by using desktop. Even, it can work similar with a native application.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"38 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124387109","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 existing works suggest that the N<inf>x</inf> × N<inf>y</inf> two dimensional (2-D) antenna array is almost surely able to recover up to ⌈N<inf>x</inf>/2⌉ ⌈N<inf>y</inf>/2⌉ two dimensional (2-D) DoA. In this paper, a new 2-D (azimuth and elevation) DoA estimation method using a minimum sparse ruler based rectangular array of antenna is evaluated. The minimal sparse ruler is used to determine which antennas that have to be deactivated and which antennas that should be remain active. Therefore, it is possible to deactivate some antennas in the uniform rectangular array (URA) leading to a sparse rectangular array (SpRA). While minimizing the reduction in the quality of the resulting DoA estimation with SpRA, the selection and averaging procedure are adopted to tackle these elements. This approach is possible for uncorrelated sources as the covariance matrix of the impinging signals on the URA contains redundant elements. The selection and averaging procedures are adopted to tackle these elements. These steps are followed by the execution of the MUSIC algorithm to compute the 2-D DoA estimates. The simulation study shows that it is possible to employ only 25-antennas in SpRA in order to estimate the azimuth (ϕ) and the elevation (θ) angles of up to 19 sources. The combinations of (ϕ) and (θ) is drawn from the range of 00 ≤ ϕ ≤1800 and 00 ≤ θ ≤ 900. The separation in azimuth and elevation angles between sources is at least 100.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129188521","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 good website should be readily accessible to every group of users. General users or users with disability should be able to access and understand the messages in a website equally well. However at the present, many people with visual impairment cannot access a website readily: they cannot search for information, in particular. Specifically, some university students in Thailand have problems accessing a website and understanding its content due to the website was developed by developers and associated personnel that lacked the knowledge and understanding of the principles that affect universal website accessibility and acceptance. This study, therefore, propose a conceptual framework based on the UTAUT theory of website acceptance. In addition to the main variables in the original theory which are applicable only to general users, two more main variables were included in this framework: perceived convenience and perceived reliability. Two new moderators were added to it as well: web accessibility and vision impairment level. These extra variables and moderators were added in order to incorporate users' intention to use a website and their usage behavior in this framework. This framework would be of value to developers and associated personnel to help them understand the valid website design requirements for university students with visual impairment.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131389025","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}

This type of network has different sets of requirements than other network types. It needs to effectively work with unreliable wireless channel condition. IETF proposed IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL) for addressing lossy environment problem. However, many important mechanisms of RPL protocol are underspecified. In this paper, we examine the performance of the route maintenance processes that are provided in RPL protocol (the combination of Neighbor Unreachability Detection Mechanism (NUD), Objective Function Zero (OF0) and The Minimum Rank with Hysteresis Objective Function (MRHOF)). Both practical and simulation experiments are conducted. The results from the practical experiments shows that the performance in term of Packet Reception Ratio from the combination between NUD and MRHOF is better than the combination between NUD and OF0. Moreover, the simulation experiments are also conducted to explore the best approach to improve the route maintenance processes by modifying two parameters in NUD and MRHOF mechanisms. The results from the simulation experiments indicate that when the data rate is low, modifying the value of the parameter in MRHOF can significantly improve the performance of the route maintenance processes but the careful consideration is required.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124864799","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 use of devices, in educational sectors, is rising day by day. Children with autism are one of the most benefited parts in this area. If the gadget is a touchscreen assistive tool, then the interest of an autistic child is increased. Devising and designing an interactive interface system for autism children with the help of participatory interface design process that has been guided with autistic children before and encouraged us to develop the touchscreen assistive learning numeracy and calculation system, named Play and Learn Number(PLaN). The application mainly focused on teaching numeracy and calculation cause without having a basic idea on numeracy and calculation regular life is hard to move on. We also focused on user interface design with some latest approaches like dot matching and puzzling which will be applied in the application. The PLaN application is also usable for teachers and parents to train and educate the autism children; it will also help to grow their interest in learning as several reinforcements are included in it. It is assumed that after establishing of this application, the autistic child will be able to learn more than before. This application will also help the children to memorize and recognize the numbers with or without sequence through the animated pictures and interactive learning application. Finally, this paper described the user interface design process broadly for forming PLaN to teach basic numeracy and calculations to children with autism.","PeriodicalId":267403,"journal":{"name":"2017 9th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132815243","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}
