This applies to forensics/fingerprinting

1. For two prints to be made by the same source, the ridge characteristics must be present in both impressions and in the same RELATIVE area. Why relative and not exact?

Expert Solution

RIDGE CHARACTERISTICS:

Fingerprints have long been used for forensic identification purposes thanks to features within their patterns called ridge characteristics or minutiae. All fingerprints fall into one of three basic overall patterns, the arch, the loop, and the whorl.

In the biometric process of fingerscanning, a ridge is a curved line in a finger image. Some ridges are continuous curves, and others terminate at specific points called ridge endings. Sometimes, two ridges come together at a point called a bifurcation. Ridge endings and bifurcations are known as minutiae

Ridges are important for finger print identification.

Ridges are different from finger to finger thats why ridges are not same. But they have same relative area.

Ridge Characteristics

Bifurcation. The point at which one friction ridge divides into two friction ridges.
Enclosure. A single friction ridge that bifurcates and rejoins after a short course and continues as a single friction ridge.
Short Ridge. Friction ridges of varying lengths.

1/ Two strings made of the same material are subjected to the same tension (therefore the speed of sound will be the same in the two strings) but have different lengths. The first rope, A, is 80 cm long and the second, B, is 60 cm long. They are vibrated at various frequencies to produce standing waves. Consider the first six partials of the two strings and determine which of the partials of string A will have the same frequency...

Consider two wires made of the same material: 1) If both wires have the same radius, but wire 1 is half the length of wire 2, what is the resistance of wire 1 in terms of wire 2? 2) If both wires have the same length, but wire 1 has three times the radius of wire 2, what is the resistance of wire 1 in terms of wire 2?

Two point source three meter apart are driven by the same oscillator at a frequency of 800 hz. The sources emit energy in the form of spherical waves. An observer initially hears a maximum at a distance 10 m along the perpendicular bisector of the line joining the two sources. What distance (in m) must observer move along a line parallel to the line joining the two sources before reaching a minimum intensity? (Assume the speed of sound is 343...
