<span lang="EN-US">This paper presents a visual tracking system to support the movement of the robot head for detecting the existence of objects. Object identification and object position estimation were conducted using image-based processing. The movement of the robot head was in four directions namely to the right, left, top, and bottom of the robot head. Based on the distance of the object, it shifted the object to many points to </span><span lang="IN">assess</span><span lang="EN-US"> the accuracy of the process of tracking the object. The targeted objects are detected through several processes, namely normalization of RGB images, thresholding, and object marking. The process of tracking the object conducted by the robot head varied in 40 various object points with high accuracy. The further the object’s distance to the robot, the smaller the corner of the movement of the robot produced compared to the movement of the robot head to track an object that was closer even though with the same distance stimulant shift object. However, for the distance and the shift of the same object, the level of accuracy showed almost the same results. The results showed the movement of the robot head to track the object under the head of the robot produced the movement with a larger angular error compared to the movement of the robot head in another direction even though with the stimulant distance of the same object position and the distance shift of the same object.</span>
As the complement of the stored multimedia presentation, live multimedia presentation (LMP) is similar to the stored multimedia presentation except for the process of selecting, authoring, constructing and playing out the multimedia elements are done during presentation time. Unfortunately, there is no established model of LMP as well as in stored multimedia presentation with its SMIL. This paper proposes some basic concepts for developing any LMP application, and then from such concept we design a model of LMP using formal definition. Finally, to verify the model we used scenario-based and developed an application as a tool to accomplish the verification process.
Currently the vocational education has been oriented to the educational processes in which focusing on the development of the student in order to ready to work professionally and ready to improve their self-potential in particular field work. Meanwhile, today and future jobs in various business sectors and industry are still growing and developing towards green jobs. If there is no counter and solution for this growth of green jobs, then it would create a new gap between the output’s competencies of vocational education and the qualification that needed by various business sector and industry. After studying some latest literatures, it was found that there is no any explicitly and concretely both concept and definition of green jobs in the vocational education curriculum (Curriculum 2013). Thus, this paper presents the urgent and such a challenge to change the philosophy of vocational education towards green jobs and ecology oriented.
These days, the Internet of things (commonly abbreviated as IoT) has been applied in various industrial sectors such as manufacturing, health, restaurant, electricity generation, transmission, and distribution, etc. Therefore, IoT learning materials need to be included in the learning process both at the college and high school level. The most common obstacle is the lack of learning media about IoT. This paper reports on the process of developing an IoT laboratory work (lab work) learning media based on the Arduino UNO and NodeMCU microcontroller. Furthermore, this paper also discusses the results of the feasibility test on learning media. The stages of the research are need assessment, planning, development and implementation, and also evaluation. Outcomes of this development process are the Arduino and NodeMCU-based IoT lab work modules, short manuals and lab sheets. Product testing with student respondents shows that the Arduino and NodeMCU-based IoT lab work modules, manuals and lab sheets are considered to be very feasible for use in learning. The test results show students considered this module can increase learning interest and make it easier for them to understand IoT learning materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
