Multiple-angle incidence resolution spectroscopy (MAIRS) has been improved to be an advanced algorithm so that the Cartesian structure in organic thin films can be analyzed. The infrared MAIRS technique was originally proposed as a totally new spectroscopic technique to reveal structural anisotropy in thin films on an infrared-transparent substrate, which yields both in-plane- (IP; X and Y) and out-of-plane (OP; Z)-mode spectra from an identical sample. Since this technique employs an analytical concept based on a signal decomposition of light intensity (not absorbance spectra), the algorithm intrinsically has high potential for further development. In the present study, the theoretically deduced matrix that correlates the light intensity to the angle of incidence has been modified to further decompose the IP-mode spectrum into X and Y components. As a result, anisotropic measurements of infrared spectra of thin film have become possible for the X, Y, and Z directions (Cartesian coordinate) simultaneously. With this advanced algorithm, the Cartesian structural changes in a cast film prepared on a germanium substrate have readily been analyzed, and a change from the biaxial to the uniaxial film structure with aging has spectroscopically been revealed. 相似文献

Highly efficient power coupling of up to 97% between a d.h. laser and a multimode step-index fibre is demonstrated by employing a tapered fibre launcher. Also, it is shown theoretically that a tapered end increases the effective numerical aperture of a fibre. For a Lambertian emitter, the use of a taper launcher permits the maximum coupling efficiency allowed by the Liouville theorem. 相似文献

This paper presents an optimal method for the separation of reflected and transparent layers from real-world scene images.
Whereas past research has been applied to indoor environments and static cameras, our technique can be used for outdoor scenes
and motion cameras. The method is based on spatio-temporal analysis, especially using epipolar plane images (EPI). The edge
and color information of EPI has been used to segment the areas on EPIs efficiently and separate the reflected and transparent
layers. This method can be used for refining building textures by removing reflections from captured images for the purpose
of city modeling. 相似文献

Various data mining methods have been developed last few years for hepatitis study using a large temporal and relational database
given to the research community. In this work we introduce a novel temporal abstraction method to this study by detecting
and exploiting temporal patterns and relations between events in viral hepatitis such as “event A slightly happened before
event B and B simultaneously ended with event C”. We developed algorithms to first detect significant temporal patterns in
temporal sequences and then to identify temporal relations between these temporal patterns. Many findings by data mining methods
applied to transactions/graphs of temporal relations shown to be significant by physician evaluation and matching with published
in Medline. 相似文献

Ambient intelligence, ubiquitous and networked robots, and cloud robotics are new research hot topics that have started to gain popularity among the robotics community. They enable robots to acquire richer functionalities and open the way for the composition of a variety of robotic services with three functions: semantic perception, reasoning and actuation. Ubiquitous robots (ubirobots) overcome the limitations of stand-alone robots by integrating them with web services and ambient intelligence technologies. The overlap that exists now between ubirobots and ambient intelligence makes their integration worthwhile. It targets to create a hybrid physical–digital space rich with a myriad of proactive intelligent services that enhance the quality and the way of our living and working. Furthermore, the emergence of cloud computing initiates the massive use of a new generation of ubirobots that enrich their cognitive capabilities and share their knowledge by connecting themselves to cloud infrastructures. The future of ubirobots will certainly be open to an unlimited space of applications such as physical and virtual companions assisting people in their daily living, ubirobots that are able to co-work alongside people and cooperate with them in the same environment, and physical and virtual autonomic guards that are able to protect people, monitor their security and safety, and rescue them in indoor and outdoor spaces. This paper introduces the recent challenges and future trends on these topics. 相似文献

This article presents the development of a timberjack-like pruning robot. The climbing principal is an imitation of the climbing
approach of timberjacks in Japan. The robot’s main features include having its center of mass outside the tree, and an innovative
climbing strategy fusing straight and spiral climbs. This novel design brings both lightweight and high climbing speed features
to the pruning robot. We report our progress in developing the robot, focusing on straight climbing, behavior on uneven surfaces,
and pruning. 相似文献
