In this Ph. D thesis, the main significant contributions are: formulation of a new non-linear membership function using fuzzy approach to capture and describe vagueness in the technological coefficients of constraints in the industrial production planning problems [1-3]. This non-linear…

In order to measure the performance of a parallel machine, a set of application kernels as benchmarks have often been used. However, it is not always possible to characterize the performance using only benchmarks, given the fact that each one…

Regional anaesthesia has become more popular in recent years with an emphasis on cost effectiveness, bed occupancy, and reduction in hospital acquired infections (HAIs). Anaesthesia is a worrying time for any patient, but now the emphasis is to encourage patient…

BACKGROUND: The extubation failure rate in our burn patients is 30%.

OBJECTIVE: To evaluate the influence of the 30 min spontaneous breathing trial on extubation outcome in burn patients.

METHODS: A prospective, observational study in a burn intensive…
