We describe here a 62-year-old woman who presented with a perivascular epithelioid cell tumor arising in the sigmoid colon. Computed tomography revealed a 5-cm-sized intraluminal fungating mass. Histologically, the tumor consisted of plump, epithelioid cells with abundant clear-to-lightly eosinophilic cytoplasm and round nuclei, arranged in an alveolar or(More)
Localization of indoor mobile robot is one of main issues on service robot area. Various sensor systems like odometry, INS, ultra sonic, laser lange finder (LRF), RF range systems such as UWB and chirp spread-spectrum (CSS), and vision have been applied to solve localization problem. RFID system can be a solution due to the low cost and scalability. A RFID(More)
A method for using radio-frequency identification tag floor based localization (RFTL) for indoor mobile robot localization is proposed. This method does not suffer from illumination or line of sight impairment issue, and it is less affected by the environment than is conventional localization. However, it faces an inherent limitation, in terms of its low(More)
A radio-frequency identification (RFID) tag floor based localization is recently proposed indoor mobile robot localization method that utilizes super-distributed RFID tag infrastructure (SDRI) installed on a working area. An RFID tag floor localization (RTFL) method is easy to scale up the working area and the number of robots and is reliable in the(More)
This paper proposes an efficient method to locate the automated guided vehicle (AGV) into the parking position using artificial visual landmark. For automated transshipment system in container terminals, the port AGV is used to transport containers autonomously and efficiently. To co-operate with the transfer crane, accurate guiding and positioning system(More)
In this paper, we propose a support vector machine parameter tuning algorithm using dynamic encoding algorithm for handwritten digit recognition. This method uses dynamic encoding algorithm for search (DEAS) which is recently proposed optimization algorithm based on variable binary encoding length. The radius/margin bound is used for the estimation of the(More)
Software birthmarks are unique and native characteristics of a binary executable program that can be used for detecting software piracy. API (Application Programming Interface) calls in an MS Windows binary executable can be used as software birthmarks when there are no source codes available to detect software similarity. However, it is inefficient to(More)
This paper presents an efficient method that locates the automated guided vehicle (AGV) into a specific position using vision-based system. For an automated transshipment system in the container terminal, it is necessary for the AGV to recognize the current position of the transfer crane, so that the port AGV locates itself into the working area of the(More)
