—A single-chip MPEG-2 MP@ML codec, integrating 3.8M gates on a 72-mm 2 die, is described. The codec employs a heterogeneous multiprocessor architecture in which six microprocessors with the same instruction set but different customization execute specific tasks such as video and audio concurrently. The microprocessor, developed for digital media processing,… (More)
— Interconnect delay is dominant in today's high speed VLSI circuits and there have been various works to resolve it ,,. A repeater insertion tool " RePertory " has been newly developed to solve the interconnect timing problem on a 300MHz 128-bit 2-way Superscalar Microprocessor. Because of its practical simple algorithm, the location of over 5700… (More)
In this paper, we propose a novel web content summarization method that creates a text summary by exploiting user feedback (comments, annotations etc.) in the social bookmarking service. We first analyze the feasibility to utilize user feedback in the summarization, and then demonstrate how the social summary which best represents the topics of the web… (More)
In this paper, we describe a key issue of the review phase of litigation cases under the Discovery system, namely when to stop reviewing potentially relevant ("responsive") documents. UBIC's Lit i View software has recently been augmented with a Quality Monitor (patent pending) and a so-called Endpoint Detector (patent pending) which provide sound… (More)
BACKGROUND The purpose of this study was to evaluate the influence of image-free computer-assisted navigation system update on outcome in total knee arthroplasty. METHODS Thirty-three knees were replaced using the Stryker 3.1 image-free navigation system and 49 knees were replaced using the Stryker 4.0 system. One surgeon took part in all procedures as… (More)
A young female athlete suffered from the residual instability of the knee after anterior cruciate ligament (ACL) reconstruction with hamstring autograft. The 3-dimensional (3-D) CT scan showed the "high noon" positioning of the primary femoral bone tunnel. The revision surgery with anatomic double-bundle technique was performed two years after the primary… (More)
\An asymptotically optimal learning controller for nite Markov chains with unknown transition probabilities ,"
To detect useful information for an artificial heart control system, we paid attention to the autonomic nervous system. For stable recording, we used vagal nerve activity in chronic animal experiments using healthy adult goats in an awake condition because this nerve was sufficiently bold and large enough. Vagal nerve discharges were successfully recorded… (More)
