ELECTRICAL DISTURBANCE IN WEIGHING.

Parallel Disturbance Force Compensator for Electrical Machines

The objective of the research is to diminish unwanted forces generated by rotation and unbalanced rotor mass on the rotor of an electrical machine. These forces, dependent on rotational speed, cause vibration that, when occurring in the machine’s natural frequency, causes severe problems. Extra windings are built in the stator of the machine, and they are supplied with current to create an oppo...

Dynamic Weighing

In fabricating flowmeters, the meter's calibration is its final and accuracy determining step that comprises a great time consumption relative to its completion from its single component parts. Thus calibration (unless the respective time of calibration for a flow meter is not minimized) may represent a relevant contribution to fabrication costs. High-accuracy liquid flow calibration facilities...

Necrotizing Enterocolitis in Infants Weighing

Over a 4 year period, nine of 180 (5%) infants weighing less than 2000 G,admitted to the Aga Khan University Hospital (AKUH) developed necrotizing enterocolitis (NEC). An outbreak of NEC occurred in 1989, during which six infants developed the clinical illness. Overall incidence was 1.1%. Thirty-one birth weight and gestation matched controls were selected for comparison. Risk factors usually c...

On circulant weighing matrices

Algebraic techniques are employed to obtain necessary conditions for the existence of certain circulant weighing matrices. As an application we rule out the existence of many circulant weighing matrices. We study orders n = 8 +8+1, for 10 ~ 8 ~ 25. These orders correspond to the number of points in a projective plane of order 8.
