composition is the proportion of fat‚ muscle‚ and bone in the body. There are many methods to know someone’s body composition and body fat percentage such as measurement with calipers‚ underwater body‚ fat test‚ the bodpod‚ DEXA scan and bioelectrical impedance analysis. (Kravitz‚ Len‚ Ph.D. & H. Heyward‚ Vivian‚ Ph.D.). The calipers method involves measuring the skinfold thickness of the layer of fat just under the skin in several parts of the body with calipers. The results are then calculated and

squirrel-cage induction machine‚ there are no external electrical connections to the rotor. The other type of rotor construction is known as a wound rotor. Torque is produced in an induction motor assuming purely resistive impedances for the rotor conductors. However‚ the impedances of the conductors are not purely resistive. Because the conductors are embedded in iron‚ there is significant series inductance associated with each conductor. The rotor slows down from

Table 2 shows the “expected values” of vision impedance on the human subjects’ depth perception. Tables 3 and 4 show a contingency table with observed‚ expected‚ and summation values.

Assignemnt 3 – Sound Construction Technology 5 – 200471 Damir Kukic 17038124 Q1. List and explain three ways that noise can be reduced at the source. Noise can be reduced at the source by placing noise in sound proof enclosure. A special enclosure does not need to be constructed for the noise source. Structure-borne noise can be eliminated by flexible connections to the services and placing machinery on resilient supports. Q2. Explain how noise attenuation differs for a point source

Why use regulated power supplies? The ideal voltage-regulated power supply would have the following features: 1. Zero output impedance at DC and at all frequencies 2. Zero regulation (constant DC output voltage) for a wide range of AC line voltages and over the entire range of load currents that are required by the powered circuitry. 3. Zero power dissipation. 4. Instantaneous recover from changes in line voltage and load current. 5. Overload protection so that normal operation is automatically
