Although many papers have been published on visual tracking and visual servoing for vision‐based robotics, there are only a few research projects studying using vision to improve standing and walking stabilization for legged robots. In this paper, we proposition a “Visual Lifting Bipedal Walking” strategy, which uses visually measured information to control the robot to...

AIM The aim of the present study was to determine whether inebriated patients falling on stairs sustain more severe head injuries than sober patients because of a delayed reaction time and a pathological coagulation and clotting system. PATIENTS AND METHODS The files of 140 head-injured patients who came to admission after falling on stairs were retrospectively reviewed with respect to demogr...

Rook theory has been investigated by many people since its introduction by Kaplansky and Riordan in 1946. Goldman, Joichi and White in 1975 showed that the sum over k of the product of the (n− k)-th rook numbers multiplied by the k-th falling factorial polynomials factorize into a product. In the sequel, different types of generalizations and analogues of this product formula have been derived ...

Streambed hydraulic conductivity (K) values were determined at seven stream transects in the Platte River Basin in Nebraska using different instream measurement techniques. Values were compared to determine the most appropriate technique(s) for use in sandy streambeds. Values of K determined from field falling- and constant-head permeameter tests analyzed using the Darcy equation decreased as p...

BACKGROUND Cancer rates of the head and neck are traditionally linked to public health issues. OBJECTIVE To describe the epidemiology of head and neck cancer in the United States. DESIGN AND SETTING National Cancer Institute's Surveillance Epidemiology and End Results (SEER) program. RESULTS A total of 75,000 cases of head and neck cancer were diagnosed in 2001. Incidence is rising in thy...

A virtual avatar or autonomous agent is a digital representation of a human being that can be controlled by either a human or an artificially intelligent computer system. Increasingly avatars are becoming realistic virtual human characters that exhibit human behavioral traits, body language and eye and head movements. As the interpretation of eye and head movements represents an important part ...

We investigate the coefficients generated by expressing the falling factorial (xy) as a linear combination of falling factorial products xy for l, m = 1, . . . , k. Algebraic and combinatoric properties are discussed, some in relation to Stirling numbers.

PURPOSE To investigate the relationship between postural metrics obtained by dynamic visual stimulation in a virtual reality environment and the presence of fear of falling in glaucoma patients. METHODS This cross-sectional study included 35 glaucoma patients and 26 controls that underwent evaluation of postural balance by a force platform during presentation of static and dynamic visual stim...

background head injury is a major health problem worldwide, especially in children (1). trauma is one of the most common causes of morbidity and mortality in developed societies. traumatic injuries to the head can occur because of motor vehicle crashes, falling from heights, being beaten, and brain injuries caused by child abuse (4). the most common causes of head trauma in children are child a...
