Fundamentals of Computer is a compulsory course of non-majors in many universities of China. In this paper, we explore the reform on this course for two goals. One is to redesign the teaching content: from operation oriented to computational thinking oriented. Computational thinking is one of the most important ability for 21st century and has become the primary goal of computer foundation education...
As the main goal of network media service transmission, to meet and enhance the quality of experience (QoE) for users, and optimize transmission control mechanism. High-definition (HD) streaming media technology demands larger bandwidth. While QoE evaluation needs to consider multiple paths network transmission quality of service (QoS), path payload distribution, service features and other attributes...
As software structures grow, it becomes increasingly difficult for those new to any software source code to conceptualize the mostly invisible structure. Historically program structures have been challenging to visualize. This paper contributes a 3D flythrough approach called FlyThruCode for visualizing facets of program structure. A prototype demonstrates its viability, and an empirical study investigates...
The flipped classroom reconstructs the learning process of the students. In view of the reflection problems of flipped classroom based on small private online course (SPOC), this paper takes the course “Network Technology and Application” in engineering colleges as an example to explain the implementation process of the flipped classroom, which proposes flipped classroom teaching practice process...
The existing radio access network system is static and rigid which could not satisfy the communication requirements of the modern society — flexibility, mobility and intelligence. This paper studies the problems of virtualized resource allocation with multi-objective mapping in heterogeneous radio access network. First, a mathematical model of the multi-objective mapping for virtualized resources...
There has been some adaptive algorithms used in the microphone array speech enhancement technology, but most of them had shortcomings like program back substitution, slow convergence and smaller voice. In our study, an adaptive noise reduction algorithm for microphone array is proposed based on an improved recursive least-square methodology. Using low complexity QR-RLS algorithm based on inverse Givens...
In the era of information network explosion, users can be connected to various forms of social networking sites anytime and anywhere through the mobile devices. Users interact between people with the way of social networks platforms. People interact with friends through the social networks platforms, and from the creation of the interests and preferences of people. Furthermore, for many brand enterprises,...
This paper proposes an offline approach to generating an optimal vacation routing plan to maximize the number of places to visit during the vacation duration. A traveling salesman problem algorithm results in a plan with the shortest path of travel given a number of stops. This solution is not suitable as a travel planner needs to take into account the operating hours and duration of stay at each...
The increased number of students (in higher education) learning programming languages makes the efficient and effective assessment of student work more important. Thus, academic researchers have focused on the automation of programming assignment marking. However, the fully automated approach to marking has its issues. This study provides an approach geared towards the reduction of marking times while...
An optimization algorithm called hybrid rice optimization algorithm (HRO) is proposed in the paper which is inspired by the breeding process of three line hybrid rice. The three line are sterile line, maintainer line, restorer line. The sterile line is hybridized with the maintainer line to produce the hybrid rice. The restorer line keeps the fine properties by self. The process of hybridization is...
With the progress of Information Communication Technology (ICT), many studies investigate the use of ICT in the community. Community welfare services have become increasingly important due to the population's aging. In this study, we investigated the issues of community welfare supporters and constructed an information sharing environment applying cloud storage service and tablets. In this environment,...
This paper proposes the parallel implementation of finite volume method based on weighted average flux (WAF) to solve the shallow water equations on a graphic processing unit. We develop two parallel programs which are 1-dimension thread block and 2-dimension thread block, respectively. We compare the performance of these two versions with a sequential program. The numerical experiment is performed...
Recently, iBeacon is popular used in many fields to push notification to visitors or customers by smart phone APP installed beforehand. Local culture protection organization, such as museum, historic relics park, etc., has the task to disseminate local culture via new IT. iBeacon and smart phone APP, two hotspots research, can be used to push and illustrate local culture information. This research...
We aimed to investigate how reading a book on a tablet computer affects sleep by measuring cerebral blood flow in the prefrontal cortex. Seven students (7 men, age: 21–32 years) participated in this study. Under a controlled illuminance environment, the subjects read a novel in printed form or on a tablet computer from any distance. As the subjects were reading, the cerebral blood flow in their prefrontal...
Gait is one of fundamental motion in human daily life. Therefore, malfunction for gait motion strongly affects the human health. Gait analysis helps to prevent the human health from the malfunction gait. This study developed a sole pressure measurement system which can provide sole pressure and pose of sole in gait motion. In the experiment, the system was applied for normal human to examine several...
It is important to know the color appearance for dichromats to improve their visual environment generally. To represent the color appearance, the Brettel model has been used. A comparison of the Brettel model and a model that is modified by considering chromatic adaptation is carried out in this study. The compassion was carried out using combinations of colors with a very small difference to determine...
This study aims to propose a system to visualize the velocity of motion, velocity/change of acceleration, and shape of trajectory based on the information measured by optical motion capture systems. It is difficult to figure out the above-mentioned information only by physical movements. The system uses various sizes of spheres and trigonal pyramids as well as colors and line segments to express velocity...
This paper examines a type of dialogue between an instructor and a humanoid robot, which is particularly appropriate for a situation wherein students listen to an instructor-robot dialogue in a classroom. The type of dialogue is extracted from comedy routines, movie plots, and a science experiment-based television program. The general structure of the dialogue is a series of activation, core, and...
Online education is a popular way for distance education in the world. The data of online education platform is explosively growing. The Big Data technologies can process and analyze the massive data and facilitate the user experience and teaching quality. This paper proposes an online education Big Data platform that aims at improving the quality of education by analyzing a large amount of data generated...
