What are the main differences between structured,<br> O-O, and agile development methods?

fgiga [73]

Answer:While structured analysis sees procedures and information as isolated segments, object-oriented (O-O) analysis joins information and the procedures that follow up on the information into things called objects. O-O analysis utilizes protest models to show information, conduct, and by what implies objects influence different articles. By portraying the items (information) and techniques (forms) expected to help a business task, a framework engineer can outline reusable segments for quicker framework usage and diminished advancement cost.Numerous experts trust that, contrasted and organized examination, O-O strategies are more adaptable, effective, and reasonable in the present unique business environment. Agile improvement techniques have pulled in a wide after and a whole network of clients.

Agile strategies ordinarily utilize a winding model, which speaks to a progression of cycles, or revisions,which depend on client criticism. Advocates of the winding model trust that this approach lessens dangers and accelerates programming advancement. Investigators ought to perceive that lithe techniques have points of interest and hindrances. By their tendency, dexterous strategies enable designers to be considerably more adaptable and responsive, however can be less secure than more customary techniques.For instance, without a point by point set of framework necessities, certain highlights asked for by a few clients won't not be predictable with the organization's bigger course of action. Other potential disservices of versatile strategies can incorporate feeble documentation, obscured lines of responsibility, and too little accentuation on the bigger business picture. Additionally, except if legitimately executed, a long arrangement of emphases may really add to extend cost and advancement time.

Match the types of AI to the correct automation tasks.

Maru [420]

Answer:

Theory of Mind : A robotic head has a face that recognizes and simulates emotions.

Self aware : A robot tries to protect itself from harm

Purely Reactive : A door automatically opens when a person steps in front of it.

Limited Memory : A personal assistant software tracks a persons travel routes and suggests shorter routes.

Explanation:

Artificial intelligence is simply a technology which enables automation. It enables system perform task without being explicitly controlled. Purely reactive systems do not store Data in memory, it simply observes what going on at the moment which is what it was programmed to do and takes a step. One the machine detects someone approaching up to a certain distance, it opens.

Limited Memory systems store information about the past and this enhances its Decison making, prediction engines, self driving cars use this kind of artificial intelligence.

Theory of Mind : Here, systems are trained to detect, understand and replicate what is understood. Once the robot identifies an emotion, it replicates it.

Self - Aware : An advanced level of AI, where systems will not only be able to replicate what they see, but also make conscious decisions as to which action to take in different circumstances.

Will give brainly

Ksivusya [100]

Answer:

Here you go!!

Explanation:

If I were to write a book I would write my steps down as in figuring out what I what to talk about. Have an Introduction- Using an introduction is needed because you need to Describe your main idea, or what the essay is about, in one sentence. ... Develop a thesis statement, or what you want to say about the main idea. ... List three points or arguments that support your thesis in order of importance (one sentence for each). I would also use a Rising action- This is needed because, To construct the plot, nearly any story can be said to use increasing action. It serves the following purposes: It generates suspense and enhances the sense of urgency around the story's central conflict or problem. Then I would do a Climax- The object of a climax is not to provide the most possible conflict or action. It's also not just about producing the character's greatest reversal of fortunes. Too often we mistake the fortunes of our character with the story's arc, and although fortune is involved, it's not our story arc's key criterion. After that, I would just add finish touches and finish it off before it needs to be shipped off to make copies.

Given the complex numbers A1 5 6/30 and A2 5 4 1 j5, (a) convert A1 to rectangular form; (b) convert A2 to polar and exponential

Deffense [45]

This question is incomplete, the complete question is;

Given the complex numbers A₁ = 6∠30 and A₂ = 4 + j5;

(a) convert A₁ to rectangular form

(b) convert A₂ to polar and exponential form

(c) calculate A₃ = (A₁ + A₂), giving your answer in polar form

(d) calculate A₄ = A₁A₂, giving your answer in rectangular form

(e) calculate A₅ = A₁/( $A^{*}$ ₂), giving your answer in exponential form.

Answer:

a) A₁ in rectangular form is 5.196 + j3

b) value of A₃ in polar form is 12.19∠41.02°

The polar form of A₂ is 6.403 ∠51.34°, exponential form of A₂ = 6.403 $e^{j51.34 }$

c) value of A₃ in polar form is 12.19∠41.02°

d) A₄ in rectangular form is 5.784 + j37.98

e) A₅ in exponential form is 0.937 $e^{j81.34 }$

Explanation:

Given data in the question;

a) A₁ = 6∠30

we convert A₁ to rectangular form

so

A₁ = 6(cos30° + jsin30°)

= 6cos30° + j6cos30°

= (6 × 0.866) + ( j × 6 × 0.5)

A₁ = 5.196 + j3

Therefore, A₁ in rectangular form is 5.196 + j3

b) A₂ = 4 + j5

we convert to polar and exponential form;

first we convert to polar form

A₂ = √((4)² + (5)²) ∠tan⁻¹( $\frac{5}{4}$ )

= √(16 + 25) ∠tan⁻¹( 1.25 )

= √41 ∠ 51.34°

A₂ = 6.403 ∠51.34°

The polar form of A₂ is 6.403 ∠51.34°

next we convert to exponential form;

A∠β can be written as A $e^{j\beta }$

so, A₂ in exponential form will be;

A₂ = 6.403 $e^{j51.34 }$

exponential form of A₂ = 6.403 $e^{j51.34 }$

c) A₃ = (A₁ + A₂)

giving your answer in polar form

so, A₁ = 6∠30 = 5.196 + j3 and A₂ = 4 + j5

we substitute

A₃ = (5.196 + j3) + ( 4 + j5)

= 9.196 + J8

next we convert to polar

A₃ = √((9.196)² + (8)²) ∠tan⁻¹( $\frac{8 }{9.196}$ )

A₃ = √(84.566416 + 64) ∠tan⁻¹( 0.8699)

A₃ = √148.566416 ∠41.02°

A₃ = 12.19∠41.02°

Therefore, value of A₃ in polar form is 12.19∠41.02°

d) A₄ = A₁A₂

giving your answer in rectangular form

we substitute

A₄ = (5.196 + j3) ( 4 + j5)

= 5.196( 4 + j5) + j3( 4 + j5)

= 20.784 + j25.98 + j12 - 15

A₄ = 5.784 + j37.98

Therefore, A₄ in rectangular form is 5.784 + j37.98

e) A₅ = A₁/( $A^{*}$ ₂)

giving your answer in exponential form

we know that $A^{*}$ ₂ is the complex conjugate of A₂

so

$A^{*}$ ₂ = (6.403 ∠51.34° )*

= 6.403 ∠-51.34°

we convert to exponential form

A∠β can be written as A $e^{j\beta }$

$A^{*}$ ₂ = 6.403 $e^{-j51.34 }$

also

A₁ = 6∠30

we convert to polar form

A₁ = 6 $e^{j30 }$

so A₅ = A₁/( $A^{*}$ ₂)

A₅ = 6 $e^{j30 }$ / 6.403 $e^{-j51.34 }$

A₅ = (6/6.403) $e^{j(30+51.34) }$

A₅ = 0.937 $e^{j81.34 }$

Therefore A₅ in exponential form is 0.937 $e^{j81.34 }$
