  Significance of Preoperative Planning Simulator for Junior Surgeons Training of Pedicle Screw Insertion

  Study Design: A prospective study to access the significance of preoperative planning simulator for junior surgeons' training of pedicle screw insertion. Summary of Background Data: Pedicle screw insertion is particularly challenging to carry out on patients with abnormal spine morphology, especially for the doctors who lack experience.

  SEMG based movement quantitative estimation of joins using SVM method with gravitational search algorithm

  Recently the surface electromyogram signal (sEMG) based motion estimation developed rapidly, which focus on intention recognition but the other information of motion is not concerned. This paper proposed a sEMG based quantitative analysis method to estimate movement of human joints, which was used to control the upper limb rehabilitation robot system by participant's own arm.

  Video-based crowd counting with information entropy

  As a key indicator of safety, the number of persons in pubic venues is quite important. However, most algorithms require a burdensome training, which is far away from practical application. In this work, we introduce a counting approach with information entropy (IE).

  An improved image dehazing and enhancing method using dark channel prior

  In fog and haze weather conditions, the outdoor visibility is greatly reduced by the atmospheric scattering. Images taken in this weather suffer from serious degradation. Image dehazing based on the dark channel prior(DCP) is considered to be an elegant solution due to its advantages of simple implementation and excellent performance of dehazing.

  Omnidirectional analysis of spatial manipulator

  Space manipulators are mainly used in the spatial loading task. According to problems of the spatial loading diversity, the testing loading installing position, and the utilization ratio of a test platform, the space manipulator is asked to evaluate the position and attitude of itself. This paper proposes the Point Omnidirectional Coefficient (POC) with unit attitude sphere/circle to describe attitude of the end-effector, which evaluates any points in the attainable space of the manipulators, in combination with the manipulation's position message, and get relationships between its position and attitude of all points in the attainable space.

  Axiomatic design method to design a screw drive in-pipe robot passing through varied curved pipes

  A screw drive in-pipe robot is promising inspection equipment for small pipes. However, most of the existing screw drive in-pipe robots have problems of motion interference and slipping inside curved or irregular pipes. These problems result from the coupled relations among the steering motion, the motion speed and the load ability of the robot. In order to deal with the problems, the axiomatic design (AD) theory is applied to evaluate and analyze the existing designs.

  Classification of Hemodynamic Responses Associated With Force and Speed Imagery for a Brain-Computer Interface

  Functional near-infrared spectroscopy (fNIRS) is an emerging optical technique, which can assess brain activities associated with tasks. In this study, six participants were asked to perform three imageries of hand clenching associated with force and speed, respectively.

  Investigation of penetration using atomic force microscope: potential biomarkers

  The penetration of cell membrane using atomic force microscope (AFM) is studied. The penetration is monitored by AFM, and the penetration force is measured for three types of cells. The dissipated energy of the cell membrane before and after drug treatment is also calculated and analysed. Experimental results indicate that AFM is an efficient tool for measuring and monitoring the penetration of the cell membrane.
