BACKGROUND Multiple sclerosis (MS), a common neurodegenerative disease, has well-described associations with quality of life (QoL) impairment. QoL changes found in longitudinal studies are difficult to interpret due to the potential response shift (RS) corresponding to respondents' changing standards, values, and conceptualization of QoL. This study proposes to test the capacity of Random Fores...

Automated visual inspection (AVI) is becoming an integral part of modern surface mount technology (SMT) assembly process. This high technology assembly, produces printed circuit boards (PCB) with tiny and delicate electronic components. With the increase in demand for such PCBs, high-volume production has to cater for both the quantity and zero defect quality assurance. The ever changing techno...

Markov decision processes (MDPs) are used to model stochastic systems in many applications, but computing good policies becomes hard when the effective horizon become very large. In “A First-Order Approach Accelerated Value Iteration,” Goyal and Grand-Clément present a connection between value iteration (VI) algorithms gradient descent methods from convex optimization use acceleration momentum ...

Multimedia is not a dream anymore. Nowadays we use images (e.g., GIF, JPEG, and BMP), videos (e.g., MPEG, AVI, and QuickTime), and sounds (e.g., MIDI and WAV) as well as alphanumerical information even on a

OBJECTIVE To evaluate the feasibility of minimally invasive transapical beating heart aortic valve implantation (TAP-AVI) for high-risk patients with aortic stenosis. METHODS TAP-AVI was performed via a small anterolateral minithoracotomy in 50 patients from February 2006 to March 2007. A balloon expandable transcatheter xenograft (Edwards SAPIEN THV, Edwards Lifesciences, Irvine, CA, USA) wa...

This paper addresses an automatic knowledge discovery process from a database of images in a context of Automated Visual Inspection (AVI). AVI is the field of computer vision addressing quality inspection of industrial products, even under informal quality models. When modelling informal knowledge, one of the most critical point turns out to be the correct and efficient translation of human exp...

The goal of our project Chrysalis is to develop a simple, inexpensive, and accurate video motion capture system. This system takes an AVI video file and creates a 3D reconstruction of the human figures in the video. Overview
