In this study, waste cooking palm oil (WCPO) was epoxidized, which then can be introduced as a potential bio-based monomer. The epoxidation reaction was carried out by in situ generated peroxyacetic acid in the presence of a sulfuric acid catalyst in a tri-neck flask fitted with a condenser. Heating and stirring were provided by a heater-stirrer. In this study, the effect of the process operating parameters such as temperature (40– 60°C), catalyst loading (1.0-2.5%) and the molar ratio of hydrogen peroxide and acetic acid to the double bond (0.5-2.0) and (0.1-0.7) respectively, were investigated and the optimum conditions were established. A maximum relative conversion to oxirane of 56.8% and iodine conversion of 53.7% could be achieved at the optimum reaction conditions namely, temperature 60 °C within a reaction time of 4 hrs, catalyst loading 2.0%, hydrogen peroxide to unsaturation (1.5), acetic acid to unsaturation (0.5), and stirring speed of 900 rpm. The findings of this study provide keys to those interested in the epoxidation of WCPO for making valuable bio-based materials such as plasticizers, adhesives, and lubricants.","PeriodicalId":308802,"journal":{"name":"2021 International Congress of Advanced Technology and Engineering (ICOTEN)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125462397","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}

Earthquake is a natural disaster that cannot be avoided or prevented, but the consequences of earthquakes can be minimized. Based on data obtained from Meteorology, Climatology and Geophysics Agency (MCGA), earthquakes often occur in Indonesia. Data obtained from earthquakes can be grouped to map the area of earthquake occurrence and an analysis will be carried out to determine the characteristics of earthquake clustering areas. The clustering in this is study conducted with two experiments, first experiment is Density-Based Spatial Clustering of Applications with Noise (DBSCAN) without dimensional reduction and second experiment is DBSCAN clustering with dimensional reduction using Principal Component Analysis (PCA). The best cluster results can be found by calculating the value of Silhouette Index (SI) of each cluster. From the two experiments, the highest SI value was obtained in experiment using PCA, which was 0.4137.

Therefore, this research paper investigates and examines the information security policy awareness in Taibah University's committee and their overall understanding of security. A qualitatively method is used to gain in depth data about TU committee’s awareness. An online survey was conducted to measure students’, faculty, and other employees’ awareness of three topics including, Taibah University security policies, information security crimes, and basic security actions. The findings of the survey shown a lack of security awareness and mostly between bachelor’s degree students. Therefore, TU institute should improve security education and provide training courses, workshops, and online libraries to raise students' awareness of security. A list of recommendations are proposed to enhance this awareness. This survey will help practitioners understand security awareness challenges and explore new and promising research opportunities in this field.

Thus, the proposed paper aims to design TRM ranging from 8.5 GHz – 11 GHz, with 15W output power while meeting half-the-wavelength size constraint. Moreover, the proposed paper focuses to devise apt architecture, opt substrate optimally, propose PCB layer and MMIC stack-up, design high-frequency transmission lines, perform crosstalk analysis and propose test-setup for validation of TRM. The proposed architecture of TRM was validated through RF budget simulation in Visual System Simulator (AWR) followed by transmission lines design in ANSYS HFSS, Multi-layer PCB design in Cadence Allegro and Crosstalk simulations in ANSYS SIwave. In a nutshell, the achieved performance of TRM was up-to-the-mark in terms of returns loss and fractional bandwidth as return losses of all high-frequency transmission lines were below -20 dB and fractional bandwidth < 40% was attained over the entire X-Band from 8 GHz to 12 GHz. Furthermore, the near-end crosstalk (NEXT) and far-end crosstalk (FEXT) were achieved to be < 7%.","PeriodicalId":308802,"journal":{"name":"2021 International Congress of Advanced Technology and Engineering (ICOTEN)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125362171","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 assignment of bug reports is essential in order to resolve bugs efficiently. In the case of open-source software developments and large projects, where many developers are engaged on different aspects of software development, it can be difficult to assign bug removal tasks to an appropriate developer. An increase in reported bugs, coupled with an increase in the number of software developers, will complicate the bug triage process. In these situations, bug triaging might be slow and may increase the Bug Tossing Length (BTL). An automated system to triage bug reports could potentially reduce BTL, as manual assignment of bug reports is tiresome, costly, and very time-consuming. The assignment of bug reporting to an irrelevant developer who does not possess sufficient experience to deal with the bug will adversely impact BTL and customer satisfaction. Text-based classification methods have the potential to make a strong contribution to automating the bug triaging process. In this research, different types of Information Retrieval and Machine Learning algorithms are used to determine the appropriate developer/s to rectify the reported bugs. This study used deep learning algorithms, such as the Bidirectional Long Short-Term Memory Network, to automate the bug triaging process. Bug reports contain textual data related to the bug information. In this research, the pretrained GloVe model is employed for word-to-vector representation of bug reports’ textual information. In this framework, developers’ activities are monitored based on their working history. To test the proposed approach, three large datasets, Net-Beans, Eclipse, and Mozilla, are used. It was observed that the proposed technique produced better results in terms of accuracy, recall, precision and f-measure compared to traditional Machine Learning algorithms for bug report recommendation.","PeriodicalId":308802,"journal":{"name":"2021 International Congress of Advanced Technology and Engineering (ICOTEN)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125881411","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}

However, power fluctuations due to solar energy variability are among the main challenges in using photovoltaic systems. One of the most critical factors that cause these fluctuations is the clouds that block the sun’s radiation. In this study, the motions of clouds are tracked, and the motions they could take in the future are estimated. Thus, in the short term, it has been tried to determine the moments when sudden solar radiation changes may occur by estimating the closeness and clearance of the sun. For this purpose, firstly, sky images are collected at regular intervals with the help of a digital camera placed in the main campus area of Afyon Kocatepe University. The Shi-Tomasi algorithm determines the points to be tracked on the collected sky images. Then, the points determined by using the Lucas-Kanade optical flow algorithm are tracked on sequential images. By analyzing the clouds’ motions, the clouds with the risk of obstructing the sun are detected, and the motion estimations are made using the calculated direction and speed information. Finally, due to the experiments performed on datasets obtained from 3 different days, sun closeness/clearance estimations at the 1-second resolution at 120 seconds time horizon are reached. The obtained results showed that the approach could be used successfully in cloud motion estimation in different cloudy conditions.","PeriodicalId":308802,"journal":{"name":"2021 International Congress of Advanced Technology and Engineering (ICOTEN)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125985326","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}
