ITE JOURNAL / NOVEMBER 1999 HIGHWAY-RAILROAD GRADE crossings are a relatively unique and sometimes perilous intersection of two transportation modes. The cost of collisions at these intersections is high in both dollars and human lives. The amount and type of sight distance provided at highway-railroad grade crossings can have significant impacts on safety. The proper calculation of these sight...

69 INTRODUCTION It has been estimated that more than 1 million deer-vehicle crashes (DVCs) occur each year in the United States, costing the traveling public more than $1 billion.1 Some of the countermeasures that have been applied to reduce DVCs include deer fencing, wildlife crossing structures, roadside reflectors, vehicle whistles, highway lighting and speed limit reductions.2–4 The install...
متن کاملa comparison between callahan and knapp procedure for hypotropia in double elevator palsy
twenty six patients with double elevator palsy (dep) (ranging from 25-90 pd), who had undergone either callahan or knapp-modified-kanpp procedure from february, 1981 to february, 1994, were reviewed. we achieved acceptable results in correction of hypotropia in primary position. three patients gained peripheral fusion and after reviewing the results we concluded that in patients having large-an...
متن کاملA novel computational procedure based on league championship algorithm for solving an inverse heat conduction problem
Inverse heat conduction problems, which are one of the most important groups of problems, are often ill-posed and complicated problems, and their optimization process has lots of local extrema. This paper provides a novel computational procedure based on finite differences method and league championship algorithm to solve a one-dimensional inverse heat conduction problem. At the beginning, we u...
متن کاملVertical transposition of the horizontal recti (Knapp procedure) for the treatment of double elevator palsy: effectiveness and long-term stability.
Full tendon width vertical transposition (Knapp procedure) of the horizontal recti is an established treatment for double elevator palsy (DEP) but the long-term stability of the surgical results have not been well studied. We undertook a retrospective study to determine the overall effectiveness of the Knapp procedure, the postoperative stability of alignment, and the influence of prior inferio...
