STUDY DESIGN Retrospective study. OBJECTIVE To evaluate the radiological results of fusion with segmental pedicle screw fixation in juvenile idiopathic scoliosis with a minimum 5-year follow-up. SUMMARY OF BACKGROUND DATA Progression of spinal deformity after posterior instrumentation and fusion in immature patients has been reported by several authors. Segmental pedicle screw fixation has ...

This paper proposes the use of radial basis function (RBF) networks in the modelling of non-linear engine processes. A pertinent application of such a model is the reconstruction of cylinder pressure based upon the instantaneous angular velocity of the engine crankshaft. Distinction is made between parametric and non-parametric models and applications to which each is suited. The structure of a...

Engine control applications require the execution of tasks activated in relation to specific system variables, as the crankshaft rotation angle. To prevent possible overload conditions at high rotation speeds, such tasks are designed to vary their functionality (hence their computational requirements) for different speed ranges. Modeling and analyzing such a type of tasks poses new research cha...

Current practices of condition assessment in large marine engines are largely based on the measurement cylinder pressure using external kits, which poses challenges due to sensors synchronisation and durability issues, as well inability perform continuous monitoring. For addressing these challenges, this study aims at developing a novel method solve inverse problem predicting variations all eng...
