Penerapan Teknologi Semantic Web Pada Ensiklopedia Alam

Alam merupakan segala sesuatu materi yang hidup dan materi yang bukan hidup. Dalam kata lain alam adalah lingkungan yang tanpa kegiatan manusia. Informasi mengenai alam di internet terletak terpisah satu sama lain sehingga muncul permasalahan bagaimana mencari informasi tentang alam, dan bagaimana mengklasifikasikan informasi tentang alam. Terdapat metode semantic yang dapat merangkai informasi tersebut sehingga lebih mudah untuk dimengerti. Semantic yang cocok digunakan sebagai solusi permasalahan ini adalah ontologi. Ontologi nanti akan memodelkan dan menghubungkan antara entitas alam dengan beberapa entitas lainnya seperti makhluk hidup, penggolongan makhluk hidup, dan energi. Berdasarkan pengujian, aplikasi ini mampu mencari informasi tentang alam berdasarkan entitas yang dimiliki seperti makhluk hidup, penggolongan makhluk hidup, dan energi. Ketika pengguna memasukkan kata kunci, sistem dapat melakukan klasifikasi pada alam berdasarkan informasi yang sudah dimiliki

Ultraviolet Raman Spectroscopy of Single and Multi-layer Graphene

We investigated Raman spectra of single-layer and multi-layer graphene under ultraviolet laser excitation at the wavelength of 325 nm. It was found that while the G peak of graphene remains pronounced in UV Raman spectra, the 2D band intensity undergoes severe quenching. The evolution of the ratio of the intensities of the G and 2D peaks, I(G)/I(2D), as the number of graphene layers n changes from n=1 to n=5, is different in UV Raman spectra from that in conventional visible Raman spectra excited at the 488 nm and 633 nm wavelengths. The 2D band under UV excitation shifts to larger wave numbers and is found near 2825 1/cm. The observed UV Raman features of graphene were explained by invoking the resonant scattering model. The obtained results contribute to the Raman nanometrology of graphene by providing an additional metric for determining the number of graphene layers and assessing its quality.Comment: 18 pages; 5 figures; submitted for publication on February 20, 200

Forecasting wind speed data by using a combination of ARIMA model with single exponential smoothing

Wind serves as natural resources as the solution to minimize global warming and has been commonly used to produce electricity. Because of their uncontrollable wind characteristics, wind speed forecasting is considered one of the best challenges in developing power generation. The Autoregressive Integrated Moving Average (ARIMA), Simple Exponential Smoothing (SES) and a hybrid model combination of ARIMA and SES will be used in this study to predict the wind speed. The mean absolute percentage error (MAPE) and the root mean square error (RMSE) are used as measurement of efficiency. The hybrid model provides a positive outcome for predicting wind speed compare to the single model of ARIMA and SES

The Impact of Equal Employment Opportunity-Affirmative Action in U.S. and New Economic Policy in Malaysia on Employment and Reverse Discrimination

Penggubalan polisi Equal Employment Opportunity-Affirmative Action (EEO-AA) bertujuan memastikan wujud keseimbangan peluang pekerjaan di antara kaum majoriti dan minoriti di Amerika Syarikat. Di Malaysia pula, Dasar Ekonomi Baru (DEB)diwujudkan bagi menyeimbangkan status ekonomi di antara pelbagai etnik. Kajian ini pertamanya bertujuan untuk menganalisis sejauhmana EEO-AA dan DEB dapat mencapai matlamat untuk menyeimbangkan peluang pekerjaan di Amerika Syarikat dan juga status ekonomi antara etnik di Malaysia. Keduanya, untuk menganalisis sama ada EEO-AA dan DEB ini menyebabkan berlakunya “reverse discrimination”. Hasil kajian mendapati EEO-AA hanya memberi impak yang kecil kepada golongan minoriti di Amerika Syarikat. Di Malaysia pula, DEB telah berjaya meningkatkan jumlah partisipasi Bumiputera di dalam pelbagai sektor. Manakala kedua-dua polisi tidak menyebabkan berlakunya “reverse discrimination”

CAPBLAT Development and Testing: Computer-Assisted Assessment Tool for Problem Based Learning

Recent years, Computer-Assisted Assessment (CAA) has become increasingly important in education. This is indicated by many researches that focused on the development of computer-based assessment tool to help assess performances of students from various disciplines. This study contributes to education area with the research on the development of innovative computer-based tool for Problem-Based Learning (PBL) assessment. A web-based assessment tool, named CAPBLAT, has been developed. The tool incorporates some methods of PBL assessment process which framed within “Problem-Based Learning Assessment Framework”. The tool has been created for evaluating students' achievements on the PBL approach. This paper presents the development and user acceptance test of the CAPBLAT. The study utilizes the tool within two PBL classes as a medium for testing in the duration of one semester. A total of forty students participated in the testing of the tool. During the study, questionnaires were administered to students. The results concerning the assessment tool acceptance demonstrate that students showed positive feedback and accepted the USAge of CAPBLAT for the PBL assessment process. It is also proved that the use of CAA in PBL gives advantages for both of lecturers and students by providing them with detailed formative feedback on their learning achievements compared to conventional assessment. It also reduces lecturer's tedious load by automating parts of the task of marking students' work

Characterization of flow rate and Heat Loss in Heating, Ventilation and Air Conditioning (HVAC) Duct System for Office Building

A building is an assemblage that is firmly attached to the ground and provides the performance of human activities and need to be considered in the daily operation in that building. The improvements in building performance are focused on improving the energy efficiency of buildings. This is approach by designing heating, ventilation and air conditioning (HVAC) duct system due to one of the most utilized energy in maintaining building performance and environment. The objectives of this research is to calculate the air (CFM) supply in office building, to characterize the velocity and head loss in a round and rectangular HVAC ducting system at various duct thickness and to optimize the thickness of the duct in HVAC system according to ASHRAE Standard. The increasing of velocity in duct system shows the increasing of head loss. The round duct design gives the lowest velocity and head loss in HVAC system approximately around 9.35% as compared to rectangular duct at 0.06 inches thickness. Hence, the trends of the head loss and duct thickness has influenced in reducing noise in HVAC duct system in order to select the best design concepts which is round shape design

Transfer Learning with Deep Convolutional Neural Network (CNN) for Pneumonia Detection using Chest X-ray

Pneumonia is a life-threatening disease, which occurs in the lungs caused by either bacterial or viral infection. It can be life-endangering if not acted upon in the right time and thus an early diagnosis of pneumonia is vital. The aim of this paper is to automatically detect bacterial and viral pneumonia using digital x-ray images. It provides a detailed report on advances made in making accurate detection of pneumonia and then presents the methodology adopted by the authors. Four different pre-trained deep Convolutional Neural Network (CNN)- AlexNet, ResNet18, DenseNet201, and SqueezeNet were used for transfer learning. 5247 Bacterial, viral and normal chest x-rays images underwent preprocessing techniques and the modified images were trained for the transfer learning based classification task. In this work, the authors have reported three schemes of classifications: normal vs pneumonia, bacterial vs viral pneumonia and normal, bacterial and viral pneumonia. The classification accuracy of normal and pneumonia images, bacterial and viral pneumonia images, and normal, bacterial and viral pneumonia were 98%, 95%, and 93.3% respectively. This is the highest accuracy in any scheme than the accuracies reported in the literature. Therefore, the proposed study can be useful in faster-diagnosing pneumonia by the radiologist and can help in the fast airport screening of pneumonia patients.Comment: 13 Figures, 5 tables. arXiv admin note: text overlap with arXiv:2003.1314
