In the recent years, there is an increasing focus on studies concerning student's engagement in the tertiary education. Student's engagement in learning is important to guarantee a good academic result. Thus it is important to encourage engagement from students in the learning process as the more engaged the students is, the better the absorption of the knowledge a student will receive. Previous literatures...
In this study, we focus on extraction of latent topic transition from POS data. POS analysis is conducted to obtain the frequent pattern of customer's behavior. The fundamental method for POS analysis is to conduct market basket analysis. By doing Market basket analysis, the sets of products that are often bought at the same time can be extracted. In market basket analysis, however, the effect of...
With the increase of systems' complexity, exception detection becomes more important and difficult. For most complex systems, like cloud platform, exception detection is mainly conducted by analyzing a large amount of telemetry data collected from systems at runtime. Time series data and events data are two major types of telemetry data. Techniques of correlation analysis are important tools that...
The amounts of currently produced data emphasize the importance of techniques for efficient data processing. Searching big data collections according to similarity of data well corresponds to human perception. This paper is focused on similarity search using the concept of sketches – a compact bit string representations of data objects compared by Hamming distance, which can be used for filtering...
Bursty behavior normally indicates that the workload generated by data accesses happens in short time, uneven spurts. In order to handle the bursts, the physical resources of IT devices have to be configured to offer capability which goes far beyond the average resource utilization, thus satisfying the performance. However, this kind of fat provisioning incurs wasting resources when the system does...
Acquiring the knowledge about the relationship among friendship network properties and check-in behavior of users (connected in the friendship network) has several benefits such as planning advertising strategies and recommending the friends or places. This paper aims to find the impact of structural patterns hidden in the nodes of a friendship network and external environment changes in the check-in...
In signal detection for cognitive radio, it is desirable to calculate a threshold within a short observation period since noise power changes in accordance with the amplification factor and the temperature of a low noise amplifier in a receiver. This paper proposes a threshold calculation scheme with a filter bank. The proposed scheme uses a more number of noise samples output from the filter bank...
Hyperspectral image clustering is commonly applied for unsupervised classification. However, the clustering results of traditional methods are not sufficient seeing the nature of the image as a data cube with high dimensionality. In addition, the complex relations between spatial neighboring pixels are not considered in traditional methods. In this paper the fuzzy c-means clustering is revisited and...
Online learning is common techniques that used by several higher educations to improve the quality of learning, which combines face to face learning and online learning. This research discussed the effective blended learning in higher education specifically is intended to measure and evaluate blended learning implemented at one of private university in Jakarta and also do study in several private...
Information technology project failure is the problem which quite hard to avoid. The main problems of IT project failure are scope, time, and cost. These three contains is affecting to each other. Time and cost are the impact of the changing in scope. About 50% – 80% of IT Projects are defined as failure project which is mostly caused by over time and over cost. In client side, the problems come from...
In learning analytics, we use eye tracking technology to get deeper insights into the learning processes. In this paper, we propose to capture eye movements (fixation points and saccades) of learners of mathematics. The study aims at using eye tracking technology to understand the correlation between attention, gaze patterns and performance. The captured data will help us understand the relationships...
The present study attempts to prove the spatial modes of the commercial district of the Ruins of St. Paul's methodologically with space syntax, axis analysis method. The study particularly selects three points of time — i.e., 1912, 1986, and 2015, respectively — in order to study the spatial structural changes of the district, and it attempts to predict the development tendency of this commercial...
The researches relevant to age-related changes have been the significant subject causing more and more attraction. This study is to investigate age-related changes of event-related potentials with detrended partial cross-correlation analysis (DPCCA) [11,12] to explore the discrimination between the young and the older. We hypothesized that the DPCCA coefficients were affected by age-related changes...
English is the most important international communication tool in the word. How to teach students to learn English in Non-English speaking countries is always a major task for education. Today, learning for fun and learning from life experience would be a better policy for learning English, especially for children. For the reason that, video is a good media suitable for learning languages, which can...
The term "True Consciousness-Only Realization" was clearly delineated by Tripitaka Master Xuanzang of the Tang Dynasty who made his famous pilgrimage to India to obtain Buddhist scriptures. During Xuanzang's subsequent travel across many kingdoms, he engaged in a full range of debates with Hinayanists to distinguish Mahayana Buddhism from the Hinayana, and to refute their erroneous understanding...
The aim of this study was to investigate the impact of the cultural factors on the acquisition of second language from the subjects, selected from registered students in university of science and technology. The subjects in this study were selected from the registered students in English learning courses in university of science and technology. Sixty-nine (69) undergraduates were made up two in-tact...
In recent years, large-scale warehouse has become remarkable. In the work of the warehouse, it is considered that travel time in the order picking occupy the large part of the total work time. Methods of changing product placement has been widely studied. But there is no method of changing product placement after the start of order picking. In this study, we propose the dynamic product placement method...
The problem of the centralized caching is studied in a two-layer network. The first layer of the network is constructed by a server and K1 helpers, and the second layer consists of K1 orthogonal sub-networks, each of which contains a helper and K2 users. The pioneer caching design in the two-layer network is to directly apply the Maddah-Ali & Niesen (MAU) centralized caching [1] into individual...
Objective of the paper is to evaluate metrics of automatic evaluation of machine translation output using manual metrics — fluency and adequacy. We tried to answer the question to which extent the manual evaluation correlates with the automatic evaluation of MT output from/to Slovak to/from English. We focused on metrics based on the similarity and statistical principles (WER, PER, CDER and BLEU-n)...
Background subtraction is a basic task of video analysis. Many methods have been proposed earlier for background subtraction, it is still challenging. In the present work, a novel method using canonical correlation analysis for background subtraction is proposed. The correlation between current image and background image obtained through canonical correlation analysis is used to detect the foreground...
