Parameter measurement of 3D soft tissue model is of great theoretical significance and application value in virtual surgery training simulation system. To solve the problems of existing soft tissue parameter measurement methods with high complexity, we propose a fast and effective parameter measurement method. We adopt a pillow as test material and exert pressure on it to simulate the parameter measurement...
This paper proposed a novel three dimensional motion detection design. This design consists of a bionic microlens array, which integrates an aberration limited four-lens system and a CMOS image sensor to mimic insect compound eye vision. The microlens array, made from time multiplexed SF6/O2 plasma and PDMS (polydimethylsiloxane)-molding, is directly placed on the top of CMOS image sensor. A LED testing...
Creating entertaining and educational books not only requires providing visually stimulating content but also means for students to interact, create, and express themselves. In this paper we present a new type of mixed-reality book experience, which augments an educational coloring book with user-generated three dimensional content. We explore a “pop-up book” metaphor and describe a process by which...
Something about 1 million skeletal defects are reported each year, which are in need of bone-grafting to be cured. Note that population of the world is getting older and so the probability of bone fractures is increasing, while dealing with this would have lots of social and economical effects. Bone grafts can be both autologous and autogenous or as an alternative, be made of nonorganic materials...
The formation and growth characteristics of intermetallic compounds (IMC) at the interfaces in nanoscale and microscale thickness Cu-Sn-Cu sandwich structure (with different solder layer thicknesses of 130nm, 400nm and 1.5µm) during reflow soldering and aging were studied. The sandwich structure samples were fabricated by electro-plating, and followed by reflow and aging process. It was found that...
This paper will highlight some of the recent advancements in 300mm eWLB wafer development. Compared to 200mm case, 300mm eWLB wafer has more warpage and process issues due to its area increase. Thermo-mechanical simulation shows 100∼150% more warpage with 300mm eWLB wafer compared to 200mm. So various design parameters were studied to optimized warpage, such as dielectric materials and thickness,...
In this paper, evaluation of underfill materials for 3D SiP packages where micro bump interconnections and solder bumps has been presented. Characterization of underfill materials was carried out in terms of adhesion testing on various chip passivation surfaces and process optimization for void free filling. Capillary underfill materials have been evaluated for micro bump interconnections for 3D stacked...
We present preliminary results towards realization of three dimensional material implication logic with monolithically stacked TiO2-based memristive devices. As a first step towards our goal we have fabricated and successfully demonstrated resistive switching for top and bottom layer memristors of the bilayer device stack. The 3D aspect of the circuits, which is a main novelty of our work, enables...
Frog dissection practice used to be a student's laboratory work in Japanese elementary schools. It was an effective approach for learning animal's anatomy. However this practice has been stopped due to animal protection issues and implemental cost. In this study, we aimed to simulate interactive dissecting practice in the virtual space. The presented virtual frog dissection system consists of virtual...
Augmented Reality is one of the futuristic technologies that will be universally used given its potential and fascination. The innovation underpinning this research is the Augmented Reality 3-Dimentional pop-up book namely “the Seed Shooting Game”, for Grade three students, in Bangkok, Thailand. This Augmented Reality (AR) 3D pop-up Book employed a research and development process through storytelling...
Spatial augmented reality is especially interesting for the design process of a car, because a lot of virtual content and corresponding real objects are used. One important issue in such a process is that the designer can trust the visualized colors on the real object, because design decisions are made on basis of the projection. In this article, we present an interactive visualization technique which...
Stereology is an interdisciplinary method of mathematics and morphology, and is unbiased, quick, accurate, noninvasive, and has high reproducibility. It is widely used in radiation imaging and cell biology. In this paper, the confocal laser scanning microscopic images (CLSMI) of tumor cells of MCF-7 and B16/ GPR4 were quantitatively analyzed using stereological point counting method. 22 images of...
In this paper we propose a flexible task distribution mechanism in order to reduce the time spent in rendering complex 3D scenes. This kind of mechanisms are particularly useful when adopting a fine-coarse approach, that is, when distributing the rendering of a single image. The proposed mechanism has been integrated into a multi-agent architecture previously designed for distributed rendering and...
This study was concerned on the growth behavior and the size characteristics of the interfacial intermetallic compounds (IMCs) between solder and Cu substrates during isothermal aging. Through the analysis of the 3D volume, 2D area, and the thickness of the IMC, a scientific method of characterization of the IMC's thickness size was found. That is using the image analysis software to calculate areas(S)...

OpenGL is a commonly used modeling tool in the virtual scene modeling. However, OpenGL graphics library does not provide advanced modeling commands, in this case, it is difficult to create complicated scene models and the models which it created are less realistic. The professional three-dimensional modeling software has strong modeling capabilities, modeling vivid, but it can not meet the interoperability...
Learning and teaching procedures need to evolve, considering the high technological profile most students have. Today's university students are steeped in a culture of technology and new devices such as smartphones, PDAs and laptops. These have found a place in students' lives as an important tool for studying. The use of these devices is widely used and seen when entering a first-year class, and...
New quasi - 3D numerical model for thermal analysis of the BGA packages is presented. The general 3D heat transfer problem is correctly transformed to the set of 2D equations for temperature distributions in different layers of the package. The complexity and CPU time of the thermal analysis are many times reduced. The results of BGA package thermal modeling are presented.
