Designing and Developing Interactive Learning Multimedia Using 3D Game Engine

. This study mainly focuses on the process of designing and developing interactive learning media by using Unreal Development Kit, which basically consists of three main parts, i.e., designing 3D objects, designing 2D objects to be used as UI (User Interface), and arranging them into a level in UDK. The next stage is having subjects to test the level and fill out a questionnaire to find out their interest and response towards the use of this new type of learning media. The subjects are randomly-picked, they are 14 ninth-grade students from several junior high schools aged 14 to 15 years old. The results show that: (1) almost all subjects give positive response towards this type of learning media; (2) this new leaning media is rated 76.9 and 64,2 by media and material experts consecutively, meaning that the media is valid to be used; and (3) all subjects would like to use this media in mobile platforms

Exploring the hidden interior of the Earth with directional neutrino measurements

Roughly 40% of the Earth's total heat flow is powered by radioactive decays in the crust and mantle. Geo-neutrinos produced by these decays provide important clues about the origin, formation and thermal evolution of our planet, as well as the composition of its interior. Previous measurements of geo-neutrinos have all relied on the detection of inverse beta decay reactions, which are insensitive to the contribution from potassium and do not provide model-independent information about the spatial distribution of geo-neutrino sources within the Earth. Here we present a method for measuring previously unresolved components of Earth's radiogenic heating using neutrino-electron elastic scattering and low-background, direction-sensitive tracking detectors. We calculate the exposures needed to probe various contributions to the total geo-neutrino flux, specifically those associated to potassium, the mantle and the core. The measurements proposed here chart a course for pioneering exploration of the veiled inner workings of the Earth.Comment: 18 pages, 11 figures, 8 table
