This paper presents a case study based on the experience of implementing a blended learning (BL) approach by SPOC to a Computer General course for all the first year undergraduates in China University of Geosciences (Beijing). It introduces ubiquitous learning environment (ULE), teaching preparation for student-centered learning, and teaching practice of the BL. The study shows that BL approach has...
CDIO(Conceive-Design-Implement-Operate) engineering teaching concept values combination of theory and practice and provide sets of theory and system of engineering education. MOOC (massive online open courses) is an emerging educational form which is used for participants everywhere to obtain courses education through learning of teaching videos and discussion and exchanges among teachers and students...
Although there have lots of studies on using static code attributes to identify defective software modules, there still have many challenges. For instance, it is difficult to implement the Apriori-type algorithm to predict defects by learning from an imbalanced dataset. For more accurate and understandable defect prediction, a novel approach based on class-association rules algorithm is proposed....
In software and IT systems engineering, personal characteristics are expected to impact performance and attitude. To clarify the optimal composition in a team of students in academic education, we researched the relationship between student personality characteristics and learning effectiveness of teams using the Five Factor and Stress theory (FFS). The results taken from a Project-based Learning...
Formal program verification is a powerful technique to ensure the correctness of programs. To perform this technique, one oftentimes needs to manually specify assertions, which is a time-consuming and error-prone task. Generating assertions automatically can significantly improve the usability of formal program verification. To decide where an assertion is needed heavily and which value range of the...
The goal of the Internet of Things (IoT) is to transform any thing around us, such as a trash can or a street light, into a smart thing. A smart thing has the ability of sensing, processing, communicating and/or actuating. In order to achieve the goal of a smart IoT application, such as minimizing waste transportation costs or reducing energy consumption, the smart things in the application scenario...
The relationship between the use of Geogebra and Technological Pedagogical Content and Knowledge (TPACK) by teachers has not been fully investigated and understood. Therefore, the aim of this study was to integrate GeoGebra technology to develop the TPACK of secondary school pre-service mathematics teachers. The participants of this study were 60 Indian teachers. Data were collected through the administration...
This paper presents an implementation of a stereo system using image processing techniques in order to determine the distance to an object from a pair of images. Starting from this, the algorithm calculates the disparity image. The distance to an object is determined by using filters, making a histogram of the disparity image and interpolating. The entire algorithm has been implemented on the BeagleBoneBlack...
In the electricity sector, new sides have emerged with the development of technology and the increasing the electric energy need. Today, electricity has become a product that is bought and sold in the market environment. Forecasting which is the first step of plans and planning have become much more important and have been made mandatory for the market participants by energy market regulators. In...
Identifying bug immediately when it is introduced can help improve the validity and effectiveness of bug fixing. Predicting bugs in software code changes makes such identification possible. Buggy changes, changes that introduce bugs into source code, can be viewed as anomalies relative to clean changes for that they are rare and irregular. Thus, anomaly detection techniques can be applied to buggy...
Software watermarking is a general tool usedto combat software piracy by embedding identifying informationinto a program. Most existing schemes of softwarewatermarking have the weak point that the security onlydepends on the stealth of the watermark structure. Besides,the watermarking is independent of program in semantic leveland can be destroyed via fairly straightforward semanticspreservingcode...
The analysis and feature extraction of surface electromyography signal (sEMG) are important in the clinical diagnosis of human function state and patients rehabilitation. The principle of rehabilitation training and implementation process is introduced in the paper. The hardware of the control system and the mode of training and the spectacle of virtual reality are designed. while the feature extraction...
The focus of this paper is on presentation attack detection for the iris biometrics, which measures the pattern within the colored concentric circle of the subjects' eyes, to authenticate an individual to a generic user verification system. Unlike previous deep learning methods that use single convolutional neural network architectures, this paper develops a framework built upon triplet convolutional...
Control methods based on sEMG obtained promising results for hand prosthetics. Control system robustness is still often inadequate and does not allow the amputees to perform a large number of movements useful for everyday life. Only few studies analyzed the repeatability of sEMG classification of hand grasps. The main goals of this paper are to explore repeatability in sEMG data and to release a repeatability...
Several defect prediction models proposed are effective when historical datasets are available. Defect prediction becomes difficult when no historical data exist. Cross-project defect prediction (CPDP), which uses projects from other sources/companies to predict the defects in the target projects proposed in recent studies has shown promising results. However, the performance of most CPDP approaches...
The extended format of HEVC, Scalable HEVC (SHVC), has been developed to serve users with mobile devices under heterogeneous networks. The SHVC can provide different bitrate, resolution, or quality formats of the same video through the one-time encoding process. As the SHVC is developed based on the HEVC, its time complexity is high and has to be reduced for practical applications. In the SHVC, it...
In a training process for DSP software developers' major schools and scientific societies see an actual problem for a kind of transformation from a traditional form of training into different remote forms, using one-to-many online training courses and interactive case study. We have analyzed many different examples of such a new forms of trainings that have been used or trialed by major technical...
For many years as a child, I did nothing but play with Lego. Eventually I had children of my own, who had a nice Lego collection themselves, but nothing you’d need machinery to sort. That changed after a trip to Legoland in Denmark.
More and more modern applications make use of natural language data, e. g. Information Extraction (IE) or Question Answering (QA) systems. Those application require preprocessing through Natural Language Processing (NLP) pipelines, and the output quality of these applications depends on the output quality of NLP pipelines. If NLP pipelines are applied in different domains, the output quality decreases...
Individual surgeons rely on residency programs as their main conduit for developing the necessary soft skills needed to succeed and excel in the operating room. One critical skill requiring subjective (qualitative) learning involves navigating through varying soft and hard tissues by hand, and, most importantly, understanding how medical instruments respond under these conditions. During residency,...
