Bidirectional cargo transport along microtubules is carried out by opposing teams of kinesin and dynein motors. Despite considerable study, the factors that determine whether these competing teams achieve net anterograde or retrograde transport in cells remain unclear. The goal of this work is to use stochastic simulations of bidirectional transport to determine the motor properties that most strongly...
Granular patterns called speckles appearing in ultrasonic echo images have become a contributing factor to deteriorated picture quality. Speckle is a kind of statistical noise that does not depend on histological distribution but it’s average size is dependent on duration and beam width of ultrasonic pulses.
In this study, we have developed a bilateral telerobotics system for a construction robot using virtual reality. The system consists of a servo-controlled construction robot, two joysticks for operation of the robot from a remote place, and a 3 degrees of freedom motion base. The operator of the robot sits on the motion base and controls the robot bilaterally from a remote place. The role of the motion...
By noting gamma correction as one of the image quality adjustment parameters, the authors create an image quality enhancement support system capable of reflecting user subjectivity. In this study, the derivation of an optimum gamma value is formulated as an optimization problem. To reflect user subjectivity, an image quality enhancement support system is realized by interactive evolutionary computation...
The present paper describes a query-by-sketch image retrieval system aimed at reducing the semantic gap between low-level features and high-level semantics by adopting relevance feedback. To reduce the semantic gap in this content-based image retrieval system, user sketches play an important role in relevance feedback. When users mark similar images of output images with "relevant" labels,...
