The interaction between oxygen absorption into liquids and bottom shear-induced turbulence was investigated in a grid-stirred tank using a laser-induced fluorescence (LIF) technique. The LIF technique enabled visualization as well as quantification of planar concentration fields of the dissolved oxygen (DO) near the airwater interface. Qualitative(More)
Cogging torque is one of the electromagnetic torque. This torque appears at the beginning of the rotation of permanent magnet electric machine, caused by the interaction between the stator slots and an electromagnetic field generated by the permanent magnet. Cogging torque pursued as small as possible so that the movement of the rotor is not hampered.(More)
A Permanent Magnet Synchronous Generator (PMSG), part of a wind turbine, has a function to convert mechanical energy into electrical energy. To rotate the first cycle, the generator is blocked by an opponent torque called detent torque/unload torque or cogging torque. This study aim to reduce the cogging torque, modifying teeth formation on the surface of(More)
Cogging torque is an outstanding issue that regularly occurs in the Surface-mounted Permanent Magnet Synchronous Generator (SM-PMSG). Cogging torque is importand to be reduced because it will generate noise and friction on the generator so it will decrease the efficiency and lifetime of the generator. For wind turbine application, the cogging torque will(More)
Cogging torque and permanent magnet electric machines are difficult to separate. This torque always remains overdue to the interaction between the magnetic field caused by the permanent magnet against the stator slot. The method proposed for reducing cogging torque in this study is the Half cylinder anti-notch design and sequence with the cutting-edge(More)
INTRODUCTION Although the number of people receiving antiretroviral therapy (ART) in Indonesia has increased in recent years, little is known about the specific characteristics affecting adherence in this population. Indonesia is different from most of its neighbors given that it is a geographically and culturally diverse country, with a large Muslim(More)
