### detection:

Edge detection
* is an important step in many shape-based recognition tasks
  - the process of detecting discontinuities in signals and images
* is used in many applications
  - to identify the edges in an image
* problem of fundamental importance in image analysis.
* provides an automatic way of finding boundaries of one or more objects in an image.

Electrochemical detection
* can monitor the disulfide form as well as the thiol form.
* is an often overlooked, though extremely sensitive, transduction method.

Intrusion detection
* blossoming science, involving detection research and reaction research.
* has a long history.
* is concerned with network security
  - crucial for providing active security in a network
  - one of the hottest growing areas of network security
  - the monitoring of a computer network with the goal of detecting an attack

Motion detection
* can play an important role in many vision tasks.
* is greatest in the peripheral visual field
  - performed by correlation of events, which are the disappearance of edges
* varies with strength of motion signal.

Determinant
* are useful in the evaluation of vector products and vector operations like the curl.
* try to give a quantitative idea of certain aspects of societies.

### determinant:

Bait
* Some baits cause death only after the baits are fed upon for several days
  - contain a sweet attractant and others use a protein or oily attractant
* are a mixture of a pesticide and food or an attractant
  - an ideal way to avoid contact with rodents because once they've eaten the bait they die
  - insecticides that have been mixed with ant attractants
  - maggot, meat or pellet, feeding maggot or pellet
  - much more effective at controlling slugs than are foliar applied insecticides
  - powerful weapons for controlling ants
  - safe, low or no odor products that are very effective on many types of insects
  - vastly different from contact insecticides
* can work quite well if the ants pick it up while foraging
  - work, but only as large quantities over long periods of time
* consist of an insecticide and an attractant, which serves to draw flies to the insecticide.
* contain active ingredients that are mixed with a pest food or attractant
  - insecticide mixed within a cellulose matrix
* containing methiocarb kill earthworms and beneficial insects.
* contains chemicals
  - specific chemicals
* exploit the natural foraging behavior of ants to find and share food.
* has odor
  - sweet odor
* includes earthworms.
* increases effectiveness.
* is devices
  - part of traps
  - temptation
  - used for lure fish
* metaldehyde can also be use to control snails and slugs.
* take advantage of the social nature and foraging behavior of subterranean termites.
* uses fresh vegetables
* work best when used in the spring and early summer
  - by combining an attractive food source with a slow-acting toxicant
  - on ant colonies with visible and non-visible mounds, such as newly established colonies

### determinant | bait:

Ant bait
* Some ant baits are for sweet feeding ants, some for protein feeding ants, and some for both types.
* work as food is shared in the nest among all the workers and the developing brood
  - only if the ants eat the bait

Live bait
* is also popular for striped bass
  - always the most natural and effective method of baitfishing
  - extremely useful on the larger predatory fish like mulloway and kingfish
* necessity for ice fishing.
* rigging great way to cover more water quicker and find fish faster
  - technique that is often under utilized

Poison bait
* are also highly effective against crickets indoors
  - illegal and ineffective
  - usually available as pellets, powder or gel
* are, of course, potentially hazardous to other wildlife, children and pets.

Rodent bait
* are poisonous to all animals to some degree.
* takes a period of time to work.
