in the current engineering practices, buildings are commonly designed for an effective lifetime of 50 years. this lifetime can increase the cost of buildings with short lifetimes and can reduce the safety level of buildings with large lifetimes. in this paper, a “service-life factor” has been defined. applying this factor into the nominal values of live, earthquake, wind, and snow loads, the ef...

PURPOSE To propose a novel method to measure the neck shaft angle and anteversion of the femur using anteroposterior and 45-degree oblique radiographs. METHODS Three human subjects were used to verify the 45-degree oblique method. The true neck shaft angle and anteversion of the femur were determined using computed tomography. The true values were compared with the values derived by the 45-de...

OBJECTIVE To describe the clinical features, etiology, and management of superior oblique tendon incarceration syndrome. METHODS This series consists of all patients I treated between September 15, 1974, and March 1, 2006, for restrictive hypertropia in which the superior oblique tendon was found scarred to the superior rectus muscle insertion after prior surgery. RESULTS Twenty eyes in 18 ...

AIM To investigate changes in fundus excyclotorsion after inferior oblique myectomy or myotomy. METHODS The records of 21 patients undergoing strabismus surgery by a single surgeon between 2009 and 2012 were examined. Only patients who had undergone an inferior oblique myectomy or myotomy, with or without horizontal rectus muscle surgery, were evaluated. Digital fundus photographs were obtain...

This article describes a new system for induction of oblique decision trees. This system, OC1, combines deterministic hill-climbing with two forms of randomization to nd a good oblique split (in the form of a hyperplane) at each node of a decision tree. Oblique decision tree methods are tuned especially for domains in which the attributes are numeric, although they can be adapted to symbolic or...

The experiments described here used event-related potentials (ERPs) to investigate the neural processes of the horizontal effect, in which visual performance is worst for horizontal and best for oblique orientations. EEGs were recorded while human adult subjects performed an orientation identification task with broad-band noise stimuli. The results showed that the difference between cardinal or...

Oblique-viewing endoscopes (oblique scopes) are widely used in computer assisted surgeries. The viewing direction of an oblique scope can be changed by rotating the scope cylinder; this extends the field of view, but also makes the geometric calibration process more difficult. Although few calibration methods have yet been developed, calibration is critical for the application of augmented-real...

The chevron osteotomy is a standard procedure by which bunions are corrected. One of us routinely performs a distal oblique osteotomy, which, to the best of our knowledge, has not been described for the correction of bunion deformities. The purpose of the present study was to compare the short- and medium-term results of the distal oblique and chevron osteotomies for bunion correction. We perfo...
