Given a double round-robin tournament, the traveling umpire problem (TUP) consists of determining which games will be handled by each one of several umpire crews during the tournament. The objective is to minimize the total distance traveled by the umpires, while respecting constraints that include visiting every team at home, and not seeing a team or venue(More)
This case report presents a 15-year-old football player who was diagnosed with a pubis stress fracture and underwent conservative treatment with satisfactory results.

This paper evaluates different parallel approaches for multipopulation genetic algorithm. These approaches are applied to solve a synchronized and integrated lot sizing and scheduling problem. In this problem, the challenge is to simultaneously determine lot sizing and scheduling for raw materials in tanks and products in lines. First, the parallel(More)

A distal femoral extension osteotomy with patellar tendon advancement (DFEO+PTA) is a common treatment for individuals with cerebral palsy (CP) who walk in crouch. Musculoskeletal modeling suggests that the typical patella baja position post-DFEO+PTA may limit one's abilities to perform sit-to-stand (STS) tasks; however, STS function has not been assessed.(More)
Given a double round-robin tournament, the Traveling Umpire Problem (TUP) seeks to assign umpires to the games of the tournament while minimizing the total distance traveled by the umpires. The assignment must satisfy constraints that prevent umpires from seeing teams and venues too often, while making sure all games have umpires in every round, and all(More)
