INTRODUCTION: The treatment of early onset scoliosis with posterior hook constructs and fusion is often complicated by the crankshaft phenomenon, which is the gradual increase in rotational deformity due to continued anterior growth in the presence of a solid posterior fusion. The combination of a posterior hook construct and an anterior fusion is considered the gold standard for prevention of ...

Received Nov 21, 2017 Revised Jan 29, 2018 Accepted Feb 17, 2018 This paper talked about an outline and execution assessment of marine motor blame recognition framework by utilising vicinity sensor. A non-linearity can be diminished by using the sensor without expanding the reaction time by applying CANopen convention. The marine motor blame location framework can measures crankshaft deflection...

This paper investigates the effect of replacing crankshaft with cam on the indicated torque during compression and power strokes in internal combustion engines. A Cycloidal cam profile was used in Revetec engine to calculate and compare the torque to a conventional engine, using a computational method. Firstly, the cylinder pressure was calculated using Ferguson equation, and then the torque ca...

Shigeru MURAMATSU, Chief Engineer Masafumi FUKUSHIMA, Chief Engineer Hiroshi MATSUNAGA, Engineer, Compressor Division, (PANASONIC), Noji-cho, This study presents experimental results on the rotary crankshaft behavior, the cylinder pressure and mechanical vibrations o£ a rolling-piston rotary compressor after shut down of the motor. It is shown as a conclusion that the most importantfactor chara...

Free-piston diesel engines are characterized by freely moving pistons without any rigid crankshaft or camshaft connected to the pistons. This allows a highly compact and e cient engine design, but requires automatic control of the piston motion. This paper present a dynamic mathematical model of a free-piston diesel engine, a control oriented dynamic analysis, and a novel computer-based piston ...

This paper presents modelling of internal combustion (IC) engine with adaptive neural networks. A radial basis function network model with both centres and weights adapted and a model with only weights adapted are compared with a fixed parameter model. The developed models are used in model based predictive control (MPC) to form an adaptive nonlinear MPC scheme and applied to engine speed track...
