An Analysis of Concentration Region on Powerpoint Slides using Eye Tracking
Get PDFPowerpoint slides have become one of the essential teaching tools in academic for both offline and online modes. It may play a useful role to facilitate discussion and information exchange. However, in our teaching experience, we find many students utilizing Powerpoint slides beyond their traditional functions. Many students fully rely on the slides as the main learning materials and, in some cases, substituting textbooks. This study intends to understand how students interact with the learning materials presented on Powerpoint slides. The interaction is measured using an eye tracker device called the Eye Tribe Tracker. Thirty sophomore and junior students are asked to participate. They are instructed to learn a topic in the subject of Introduction to Algorithm and Programming, a basic course in the computer science field. During the process, their fixation points are monitored and are related to the contents on the slides. The results are rather surprising. Many students read the slides in unexpected manners that may compromise their understanding and may lead to inaccurate interpretations
Measurement of Partial Discharge Inside Metal Enclosed Power Apparatus using Internal Sensor
Get PDFPartial discharge detection by detecting the released energy in form of electromagnetic wave during discharge using Ultra-High Frequency (UHF) antenna is one method to determine insulation system quality in high voltage system. UHF PD detection method has several advantages over conventional PD detection system such as IEC 60270 method. The advantages of UHF PD detection system are the capability to directly detect PD signal without firstly shut down, the installation system and their immunity from environmental noise. Nowadays most of electrical equipment are in form of metal enclosed model. This paper deals with measurement of PD occurrences inside metal enclosed equipment using internal sensor. The loop antenna is used for PD measurement. The experimental results show that the presence of metal box gives significant change on the PD signal detected by using loop antenna. Without metal box, the measurement sensitivity decreases because of the high level of background noise. The metal box acts as electromagnetic wave shielding and reduces the external noise. When the loop antenna placed inside metal box, the measurement sensitivity increases because of the low level of background noise inside metal box
A Study of the Number of Wavelengths Impact in the Optical Burst Switching Core Node
Get PDFIn Wavelength Division Multiplexing (WDM), several wavelengths run on an optical fiber link that connects two optical switches. The multiple wavelengths are exploited that minimized the contention problem in the Optical Burst Switching (OBS) core node. Mathematical model is used in order to investigate the impact of the wavelengths numbers OBS core node. Two performance metrics are proposed such as the steady-state throughput and the probability of burst loss using steady- state occupancy probabilities and Poisson traffic model arrivals. Numerical results show that at different values of network traffic and some design parameters such as wavelength conversion capability and the mean arrival rate could reveal the OBS performance
Performance Analysis of CSI:T Routing in a Delay Tolerant Networks
Get PDFDelay Tolerant Network (DTN) is a network that allows nodes to move dynamically and doesn’t always provide for end-to-end connection. The dynamically of nodes make the movement of the nodes becomes important. The movement model of nodes will record their behavior and this could be utilized to develop a new routing protocol in DTN. One of the DTN routing protocol that utilize it is CSI: T routing. CSI: T routing viewed a node based on their behavioral profile which is represent the mobility preference. Our study is measure the performance of CSI: T in terms of delivery probability, overhead ratio, and average latency by changing the buffer capacity, packet lifetime, and number of nodes. We used Opportunistic Network Environment (ONE) Simulator for the simulate the real-life scenario of a college-routines
Encoding of Passive Anticollision Radio Frequency Identification Surface Acoustic Waves Tags
Get PDFThis paper describes the encoding of anticollision radio-frequency identification tags based on surface acoustic waves. The study is based on the tag model with specific topology, which allows us to receive a response signal with time–frequency information. This research considers the collision case for several passive tags. Therefore, the proposal is to analyze the possibility of using several distinctive signs like frequency and time. We consider the model of passive surface acoustic wave tag, which contains piezoelectric substrate, interdigital transducer, and consecutive orthogonal-frequency-coded structures, which are placed in time slots. Similar topology makes possible the reliability of increasing tag identification in the collision case
WatsaQ: Repository of Al Hadith in Bahasa (Case Study: Hadith Bukhari)
Get PDFThe Hadith is one of the two sources of Islamic law after the Qur'an. It is a fact that there are a number of false hadith, recognised by Muslim scholars since the end of the first century of Hijra, and even earlier. In addition to the breadth of false hadith circulating among the public at this time, it is difficult to determine the source of authenticity and distinguish false from genuine. This is due to the configuration of the genuine documents which are revealed in Arabic. To that end, the authors have built a repository collection of hadith al- Bukhari in the Indonesian language. The hadith chosen have secured originality and standardisation has been applied that can assist users in learning the content of the hadith. The authors implemented a repository of translation in Bahasa of Bukhari Hadith using XML schema. To study the repository performance, we use a web presentation using PHP employing brute-force string match algorithms to display the search results based on keywords entered by the user. We analyse the results of our proposed repository implementation average searching time is faster by 0.85 milliseconds compared with the repository based on the unstructured one
Scalable Attack Analysis of Business Process based on Decision Mining Classification
Get PDFBanking crime is one of the widespread phenomena in 2016 are closely associated with the used of computer-based technology and internet networks that constantly evolving. One of them is the burglary of customer accounts through the internet banking facility. To overcome this, we need a method of how to detect a conspiracy of bank burglary case of customer accounts. The way to scalable is by get a mining decision to get a decision tree and from the decision tree to get a decision attribute value to determine the level of anomalies. Then of all the attributes decision point is calculated rate of fraud. The rate of fraud is classified through level of security of attack by the attacker then entropy gain is used to calculate the relative effort between the level of attacks in the decision tree. The results show that the method could classify three levels of attacks and the corresponding entropy gains. The paper uses decision trees algorithm, alpha++ and dotted chart analysis to analyze an attack that can be scalable. The results of the analysis show that the accuracy achieved by 0.87%
Poincaré Plot of Fingertip Photoplethysmogram Pulse Amplitude Suitable to Assess Diabetes Status
Get PDFMultiscale entropy (MSE), an estimate of the complexity of physiological signals has been used for assessing diabetes status. This method requires much computation effort. Our study aimed to examine the Poincaré plot, an easier method for computation to differentiate the diabetes status. We selected subjects and divided them into three groups including the non- diabetes (HbA1c ≤ 6.5%, n=22), diabetes with good control (6.5% < HbA1c < 8%, n=23), and diabetes with poor control (HbA1c ≥ 8%, n=17). Poincaré method used consecutive 250 data points of PPG pulse amplitudes from each subject’s right index fingertip. This method resulted in SSR, the standard deviation of the original photoplethysmogram (PPG) pulse amplitude (SD1) and the standard deviation of the interval 1 PPG pulse amplitude (SD2) ratio. The SSR in the three groups of non-diabetes, diabetes with good control and diabetes with poor control were 0.50, 0.28, and 0.23, respectively and differed between groups (P < 0.05). Our findings suggested that the Poincaré plot of right-hand PPG pulse amplitude may be convenient to evaluate diabetes status
