One of the policies that have been made by World Health Organization (WHO) and Indonesian government during this COVID-19 pandemic, is to use an oximeter for self-isolation patients. The used monitor patient if happy hypoxia which a silent killer, happens patient. To maintain body endurance, exercise needed patients, but doing too much can also cause decreased immunity. That’s why fatigue level...

Hybrid excitation synchronous motor has the advantages of uniform and adjustable electromagnetic field, wide speed range high power density. It broad application prospects in new energy electric vehicles, wind generation other fields. This paper introduces basic structure hybrid with modular stator, analyzes operation principle motor. The cooling water-cooled plate is designed, effects thicknes...

This paper, the first of a series of two, deals with the determination of optimal steady-state jacket fluid temperature profiles for dispersive tubular chemical reactors, ranging from plug flow to perfectly mixed reactors. According to Pontryagin’s minimum principle, the optimal control is of the bang-bang type for the proposed terminal cost criterion. The bang-bang switching position is numeri...

The aim of this study is to discover the characteristics of the cooling water in the cylinder head of a high-power diesel engine by using the Computational Fluid Dynamics (CFD). A 3-D geometric model of a cylinder head water jacket was previously constructed using Unigraphics software. A mesh was then imposed on the model using the preprocessor of Fluent software, GAMBIT. Three types of thermal...

When Stanley Kubrick first met his co-writer for the screenplay Full Metal Jacket, Kubrick asked him if he was familiar with “the concept of Jung” and “the concept of the Shadow, of our hidden side” (Herr 6). This fascination with the Jungian archetypes of order and chaos permeates throughout the film Full Metal Jacket in the plot, mis-en-scene, and cinematography. Furthermore, Kubrick takes th...

To improve the safety and reliability of offshore structures subject to wave loading, active vibration control problem is always one significant issues in field ocean engineering. This paper deals with near–optimal a nonlinear energy sink (NES) mechanism. By taking dominant mode structure NES into account, dynamic model steel–jacket loading presented first. Then, using parameter perturbation ap...

To improve the treatments for low back pain, new designs of total disk replacement have been proposed. The question is how well these designs can act as a functional replacement of the intervertebral disk. Four finite element models were made, for four different design concepts, to determine how well they can mimic the physiological intervertebral disk mechanical function. The four designs were...
