In recent decades, experts have presented a range of teaching methods and techniques which should increase the learning effectiveness. Naturally, no learning process is universal and reliable at the same time, and suitable for everyone and in every situation. Concept mapping is a method based on findings in cognitive psychology. We investigated how the learning process and effectiveness can be influenced...
Kaohsiung City Government coordinated with the central government to promote the Energy-Smart-City project plan, plan to propose the pioneered energy cloud for energy saving system in Taiwan. The system will help government to review energy efficiency, to explore the potential of energy saving so as to be basis for energy saving policy promotion. The system may also help citizens for energy management...
Due to advancement in minimization and mass-production, cameras are ubiquitously embedded in most of current mobile devices including phones, vehicles, robots, and augmentedreality displays. These mobile cameras are cheap and can gather in real-time large amounts of streaming data about the surrounding environment. Using an information-theoretic model of a streaming video captured by a mobile camera,...
A video is composed of a set of scenes containing semantics in the video. Since there have been existed user needs to consume scenes with respect to its semantics, scene segmentation has been focused by both industrial and research domains. This paper proposes a novel scene segmentation method. The proposed method is designed to keep information in multiple representations of shots as much as possible...
In regard to distance learning, Brazil currently lives a very special moment, as many courses are being created within that type of education. Virtual Learning Environments (VLEs) have contributed to both the growth and the popularization of distance learning. The level of management of learning processes provided by VLEs, with great interaction and tracking quality, may be singled out as a key indicator...
It is important for students to solve problems with specific requirements in the programming teaching. Our teaching system is a Moodle-based interactive teaching platform for C programming. Its online judging system can grade students code automatically. It plays an extremely important role in programming language teaching. This paper is devoted to optimizing and improving the system. We firstly analyze...
Educational data is in abundance due the nature of education in the 21st century where a significant amount of education occurs online through the advent of digital learning. There is an increase in the use of Learning Management Systems (LMS) to provide education without boundaries, and these systems hold large amounts of data. Educational data mining is the process of tapping into this rich educational...
This paper addresses the problem of building and maintaining image repositories which form the basis for world-scale visual models. The availability of these models enable capabilities such as visual localization, persistent surveillance, and structure from motion. We approach this problem through the creation of PeerAppear, a location-aware framework for extensible image annotation and peer-to-peer...
Traffic jam today in the city is one of the focus from the government, because it has a very big impact, from wasting a lot of time, the fuel until air pollution. Searching information about traffic conditions in the city has been widely available through the Twitter account @infobdg, with hashtag #lalinbdg and from the website bandung247.com. However, the rapid development of online information services...
One of the problems regarding graphics for blind individual is that we have few data on how he (she) acquires graphical information through touching. In this article, we propose a method of tracking the touch point of his (her) fingertip on graphics material using cameras (an analog of eye-tracking) for analyzing the image acquisition process. We exhibit the method on an edge-outlined tactile picture...
The NASA Earth Science Data Information Systems Project funds and operates 12 Distributed Active Archive Center(s) (DAAC) throughout the United States. Of these 12 centers, the Physical Oceanography DAAC (PO.DAAC) is committed to providing long term archival, distribution and stewardship for NASA physical oceanographic data, primarily derived from space-born satellite systems, but also including a...
Information Visualization (InfoVis) often supports the analysis of structured data that is organized in documents with specific formats such as databases, Excel tables, or comma-separated files. Informal analyses that take place without anticipation and away from the desktop, however, might involve the use of data contained in digital artifacts that lack this structure (e.g., photographs, bitmaps,...
Proposed as “data analysis anywhere, anytime, from anything”, Opportunistic Information Visualization (Opportu-Vis) [1] seeks to provide analytical support in scenarios where the data of interest is not explicitly available and has to be retrieved from digital artifacts that are not traditionally used as data sources. Examples include raster images, web pages, vector files, and photographs. This showpiece...
We propose several new concepts for providing enhanced explanations of classifier decisions in linguistic (human readable) form. These are intended to help operators to better understand the decision process and support them during sample annotation to improve their certainty and consistency in successive labeling cycles. This is expected to lead to better, more consistent data sets (streams) for...
Data wrangling is the term used by data scientists for the work of re-organising data into a new structure, before work starts on reporting or analysis. We present a prototype that applies programming by example methods to data wrangling in spreadsheets. The Data Noodles system guides the user through constructing a simple example that illustrates how they would like their spreadsheet to look. A transformation...
In this paper, we propose a novel method to extract keyframes from motion capture data for people to better visualize and understand the content of the motion. It first applies a Butterworth filter to remove the noise in the motion capture data, then carries out principal component analysis (PCA) to reduce the dimension. By detecting the zero-crossing points of the velocity in the principal components,...
Presentations are a productive approach to pass the blueprint of a work to the group of onlookers; here the framework is intended to make the presentation slides consequently from PDF document. Such produced slide can be utilized as draft slides. This draft slides will set up their last slide in a simple way, which will spare moderator's opportunity. To make presentation slide automatic, framework...
In this paper, we describe Semantic Bookworm — a tool that supports scholarly text analysis. In contrast to the text-based Bookworm tool, the Semantic Bookworm identifies semantic concepts.
Data mining is a process of discovering information from large datasets by using automated algorithms, which makes it difficult for users to intuitively understand, explore and optimize the datasets and algorithms process. Recently with the development of the visual field, researchers have been exploring how to use the visualization methods to make users intuitively understand datasets and algorithms...
We have designed a neuromorphic circuit that models directional selectivity in the visual cortex, where selected neurons fire depending on the direction of object motion, along with the size and orientation of the object. The neuromorphic circuit is biomimetic. It consists of neurons and synapses, and models biological mechanisms. Neurons (including the Axon Hillock and the Dendritic Arbor) are designed...
