The treatment of congenital dislocation and subluxation of the hip in the older child.
Two additional risks are involved in the treatment of congenital dislocation of the hip when diagnosis is made too late: avascular necrosis following the reduction, and residual coxo-femoral dysplasia. Our study and the experience that we acquired within the past 10 years on 142 hips show the value of closed reduction by slow progressive traction with abduction and internal rotation, and the value of innominate osteotomy. These are two strong points on which we can base our treatment in order to further improve the results of our efforts in this field.
This paper presents an exact combinatorial algorithm for solving the Discrete Berth Allocation Problem (DBAP) and the Hybrid Berth Allocation Problem (HBAP) with fixed handling times of vessels based on the original algorithm for solving combinatorial problems called Sedimentation Algorithm. We address the issues of DBAP and HBAP according to the Rashidi and Tsang model. To the best of our knowledge, the proposed algorithm is the first exact combinatorial algorithm for solving the general DBAP and HBAP based on Rashidi and Tsang model. Computational results prove the superiority of the proposed algorithms compared with the exact solvers based on the Mixed Integer Programming (MIP) models. Efficient C implementation enabled us to solve instances with up to 65 vessels. This resolves most of the real life problems, even in large ports.
