JPEG (/ˈdʒeɪpɛɡ/ JAY-peg) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.
JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG/JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. These format variations are often not distinguished, and are simply called JPEG.
The term "JPEG" is an abbreviation for the Joint Photographic Experts Group, which created the standard. The MIME media type for JPEG is image/jpeg, except in older Internet Explorer versions, which provides a MIME type of image/pjpeg when uploading JPEG images. JPEG files usually have a filename extension of .jpg or .jpeg.
A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion or vice versa. It is often a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path. The cam can be a simple tooth, as is used to deliver pulses of power to a steam hammer, for example, or an eccentric disc or other shape that produces a smooth reciprocating (back and forth) motion in the follower, which is a lever making contact with the cam.
The cam can be seen as a device that rotates from circular to reciprocating (or sometimes oscillating) motion. A common example is the camshaft of an automobile, which takes the rotary motion of the engine and translates it into the reciprocating motion necessary to operate the intake and exhaust valves of the cylinders.
Certain cams can be characterized by their displacement diagrams, which reflect the changing position a roller follower (a shaft with a rotating wheel at the end) would make as the cam rotates about an axis. These diagrams relate angular position, usually in degrees, to the radial displacement experienced at that position. Displacement diagrams are traditionally presented as graphs with non-negative values. A simple displacement diagram illustrates the follower motion at a constant velocity rise followed by a similar return with a dwell in between as depicted in figure 2. The rise is the motion of the follower away from the cam center, dwell is the motion where the follower is at rest, and return is the motion of the follower toward the cam center.

Come on
You can feel her coming, coming at you
She, she's staying on you
You know she's coming at you
To resist her seems impossible
You can't do it, no you can't do it, no you can't do it
Hey lady what you say
How about some fun today?
Is it yes? Is it no?
Whatever it is just let me know
Don't fake me out, out
Oh, you make me shout
Alligator woman, you don't care
You ignore my desires, it ain't fair
You just want to tease me and turn me on
I wish you would leave but I don't want to be alone, no
Hey, babe I love you so
You know I don't want to go
Even though you're real laid back
You're dressed in black
And your hair is laid back
Hey lady what you say
How about some fun today?
Is it yes? Is it no?
Whatever it is just let me know
Don't fake me out, out
Oh, you make me shout
Alligator woman, you don't care
You ignore my desires, it ain't fair
You just want to tease me and turn me on
I want you to go but I don't want to be alone, ho
You're a mess, I must confess
You make me hot, with what you've got
Your big behind, it makes me blind
Don't take me gross but you're the most
You're a mess, I must confess
You make me hot, with what you've got
Your big behind, it makes me blind
I must be gross
Aw girl, aw girl
Aw girl, aw girl
Alligator woman, you don't care
You ignore my desires, it ain't fair
You just want to tease me and turn me on
I don't want you to stay but I don't want to be alone, now
You're a mess, I must confess
You make me hot, with what you've got
Your big behind, it makes me blind
Don't take me gross but you're the most
You're a mess, I must confess
You make me hot, with what you've got
Your big behind, it makes me blind
