By switching the gradient fields of a clinical magnetic resonance imaging (MRI) scanner, magnetic objects may be moved inside the cardiovascular system of the human body. The main field of application is seen in targeted drug therapy or embolization. A successful navigation of such devices requires continuous position determination. The occurrence of magnetic susceptibility artifacts can be exploited for this purpose. This article studies the effect of magnetic microscopic objects and nanoparticles on the process of MRI image formation in several imaging sequences. An MRI simulator based on evaluation of the Bloch equation is presented and applied for the simulation of artifact formation. Also, artifact properties are studied by experiments carried out on clinical MRI scanners, using magnetic objects placed into an agarose gel phantom. The transferability of the results from the gel phantom to a real tissue environment is proven. Based on the results, a two-stage procedure for visual servoing is proposed. It is initialized by object detection, carried out in a 3D scan. Object tracking is performed on fast 2D scans by template matching. The slice position is adjusted automatically in a feedback loop in order to follow object movements perpendicular to the image plane.

This article focuses on the design and implementation of smart wearable robot glasses for human visual augmentation, which take a role to provide the refined visual recognition result to users of wearing the proposed system. The proposed system consists of a glass-type wearable device with a front looking camera, an eye looking camera, and an earphone, and signal processing units. The scene-analyzing process on the input image acquired by the front view camera is supported by an eye view camera of monitoring the eye position of user for efficient in formation processing, which is used to catch the user's visual intention and attention in given situations. The recognized results are transformed into the audio information for the user friendly information service without obstructing the users' own visual information gathering and processing, and then the result is transferred into the user earphone finally. This device can be used for the augmentation of human visual capability in various areas, museum, conference, meetings, etc. For the proposed device's feasibility, a series of experiments are performed, and the evaluation results are discussed in detail.

In this paper we present a numerical three dimensional (3D) simulation of transient heat transfer process in the human eye. A finite element method is applied to obtain the solution of a boundary value problem for a 3D transient heat transfer model in the human eye. The human eye is modeled as a com position of several homogeneous regions. The Ritz method in the finite element method is used for solving heat differential equ ation. Applying the boundary conditions, the heat radiation condition and the Robin condition on the cornea surface of the eye and on the outer part of sclera are used, respectively. Simulation results of two and three dimensional models are compared.

This paper presents an effective control algorithm to avoid physical contact between the disk and the solid immersion lens (SIL) in near-field (NF) storage systems under dynamic operating conditions such as repeatable and nonrepeatable dist urbances due to disk vibrations and external shocks. In particular, the air-gap distance between the disk and the SIL in the NFR system is less than 50 nm. Therefore, the disk and the SIL must be protected to detect the stable gap error signal (GES) during continuous control operation. In this manuscript, we propose an improved air-gap control system using a narrow-ban d disturbance filter (NBDF), which is an effective control method for enhancing the performance of the system for the rejection of repeatable and nonrepeatable disturbances In addition, we demonstrate an improved air-gap controller using a double disturbance observer (DOB) to improve the anti-shock control performance under external shocks. The double DOB uses a binomial Q filter without additional sensors, which keeps the production cost low. Finally, to evaluate the robustness of the control system with the double DOB, we apply a design method that varies the bandwidth of the Q filter.

Measurement for ship deformation has been a difficult problem for the global ship building industry and navy equipment rese arches. So far, an effective and mature method to measure the 3-D position and attitude deformation in a long term still remains unavailable. An innovative pose-relay videometric is proposed, and then a pose-relay video-metrics measurement system for ship defo rmation is developed on the basis of principle research and experimental validations. It offers solutions to key technical problems of infrared marker facture and high-precision detection and multi-cameras synchronization and control, etc. Accordingly, sea trials were carried out, and reasonable, long-time, and continuous 3-D data of position and attitude deformations between the ship head and the stern were acquired. The experiments have implied the great applicability of the proposed method in the deformation measurement and long-term monitoring of ships and similar large structures.

In this paper, we propose new SI method, the cross SI method that improves the lateral resolution and the image acquisition speed. The cross SI pattern is generated by using the 2-D diffractive grating. The acquisition of a total of 6 raw images shortens the image acquisition time. The cross structured illumination confocal microscope (CSICM) is combined with the cross SI pattern generation optics and the line scanning confocal microscope. Performances of the conventional and the cross SI are compared by the analysis of the modulation transfer function. As a result, the cro ss SI method shows similar resolution to conventional SI method. The CSICM has the two times enhanced lateral resolution than the conventional microscope, the optical sectioning ability and the fast image acquisition speed.

This paper describes the non-contact Man-Machine in terface based on the face orientations. The real-time image of the operator's face was observed by the USB camera and the changes in the darkness area of the both nostrils were utilized for recognition of the face orientations. When the operator faced to up and downward, the darkness areas of both nostrils were increased and decreased, respectively. On the other hand, the difference between two nostril areas could be caused in cases where the face was turn to the side. Here, these characteristics were reflected to the recognition of the face orientations. The developed interface was applied for the operation of the electrical wheelchair.
