Communications. Heating. Speed detection. Currently the limit where we can cloak objects... we can hide them so they cannot be "seen" using a microwave light source.
Error in a binary stream or object can be detected using Error detection techniques. (usually called EDC, or error detection and correction)Errors can be detected in many ways, but they all involve adding some redundant data along with the original message. The process for calculation of these bits is repeated while checking, and if there is a match, the data is accepted, else it is rejected (which usually involves applying data correction, or request to resend the data)Type of error detection are :Block repetition : same data is repeated twice, and at the receiver's end, checked if they are exactly the sameParity bits : a single bit is added after the sequence of certain number of data bits, to make the data's parity even or odd, depending upon the selection made.Checksum : Mathematical formula involving all bits of the data is applied, obtained result is the redundant bit, which is added for detection. Receiver recalculates and then compares the data for detection.CRC (Cyclic Redundancy Check) : another mathematical formula where all bits are used.Hash functions : predetermined hash functions for calculating the error detection code

The verb for detection is detect.Other verbs are detects, detecting and detected.Some examples are:"I detect a foul smell in the air"."He detects something"."My metal detector is detecting something"."As usual, the detector only detected junk".

Early detection of high blood pressure can limit damage to your heart and arteries!
Sensitivity is the smallest change in concentration of the analyze that can be detected by using that method. This is the slope of the calibration curve. Detection limit is the lowest concentration that can be detected by the particular method.

Paying prompt attention to the signs and symptoms of this disease, and seeing a doctor if the symptoms persist, are the best strategies for an early diagnosis of lymphoma. Early detection affords the best chance for a cure.
Advantage: non-destructive to the sample Disadvantage: High detection limit
The concentration of iodine in cereals is extremaly low, generally under the limit of detection.
