BACKGROUND The latest version of the navigation system for anterior cruciate ligament (ACL) reconstruction has the supplementary ability to assess knee stability before and after ACL reconstruction. In this study, we compared navigation data between clinical grades in ACL-deficient knees and also analyzed correlation between clinical grading and navigation data. METHODS 150 ACL deficient knee...

The RoboHelper project aims at building an effective and user friendly communication interface for assistive robots that can help the elderly live independently at home. Such communication interface should incorporate multiple modalities of communication, since collaborative task-oriented human-human communication is inherently multimodal. Data was collected from twenty collaborative task-orien...

In this paper, results ofa new sand filter design were presented. The drawer compacted sand filter (DCSF) is a modified design for a sand filter in which the sand layer is broken down into several layers, each of which is 10 cm high and placed in a movable drawer separated by a 10 cm space. A lab-scale DCSF was designed and operated for 330 days fed by synthetic grey water. The response of draw...

In this work, we propose a goal-driven collaborative task that contains vision, language, and action in a virtual environment as its core components. Specifically, we develop a collaborative ‘Image Drawing’ game between two agents, called CoDraw. Our game is grounded in a virtual world that contains movable clip art objects. Two players, Teller and Drawer, are involved. The Teller sees an abstr...

Today unpublished or "file drawer" experiments are the impetus for trial registration and reporting of all results. In 1801, Joseph Carpue, the father of modern plastic surgery, did a file drawer experiment for Benjamin West, who was President of the Royal Academy of Arts. George III had commissioned West to create the largest stained glass window ever created whose theme, the Crucifixion, was ...

On-line graph coloring algorithms have been defined in [2] as algorithms whose input graph is presented vertex by vertex, at each step the current vertex is given with all adjacencies to previously given vertices. The algorithm must color irrevocably the current vertex and has to maintain a proper vertex coloring. The simplest and best understood example of an on-line coloring algorithm is the ...

BACKGROUND The knee joint is prone to injury because of its complexity and weight-bearing function. Anterior cruciate ligament (ACL) ruptures happen in young and physically active population and can result in instability, meniscal tears, and articular cartilage damage. The aim of this study is to evaluate the accuracy of Lachman and anterior drawer tests in ACL injury in compare with arthroscop...

BACKGROUND There is a lack of consensus regarding the magnitude of load for performing the anterior drawer test in evaluating acute ankle injuries. PURPOSE To determine how much load should be applied during the anterior drawer test to detect the integrity of the anterior talofibular ligament. METHODS First, the anterior-posterior load-displacement response of nine cadaveric ankles was meas...
