Which of the languages are also regular languages, Le., can be expressed by a regular expression? Prove it by giving the regular expression that specifies the language.

Answers

This language is regular and can be expressed by the regular expression (a + b)⁶(a + b)*.

Intuitively, this is because we need to keep track of the number of a's, b's, and c's in different parts of the string, which is beyond the power of a context-free grammar. A context-free grammar in BNF notation that generates this language is S -> A C, A -> a A | ε, C -> b C | ε. A context-free grammar in BNF notation that generates this language is S -> a S c | B,B -> b B c | ε. it requires matching the number of a's to the square of the number of b's, which cannot be done with a context-free grammar. Therefore this language is regular and can be expressed by the regular expression (a + b)⁶(a + b)*.

a bollard is a post set securely in the ground in order to prevent a vehicle from entering an area or driving past a certain point. bollards are an example of controls.

Answers

Bollards are generally used as a physical barrier to control vehicle access and prevent damage to buildings, pedestrian areas, or other facilities. They are also used to direct traffic and protect pedestrians.

A bollard is a short post typically made of steel, concrete, or wood, placed in the ground and used to control vehicular access to certain areas. Bollards are used to prevent vehicles from entering certain areas, as in parking lots, sidewalks, or pathways, or to prevent vehicles from driving past a certain point, such as a bus stop. Bollards also serve to direct traffic, protect pedestrians, and create a physical barrier between the pedestrian and vehicle areas. In addition, bollards are used in areas where there is a risk of theft or vandalism, as the physical presence of the bollards is a visual deterrent. Bollards come in a variety of shapes, sizes, and materials, and can be either permanent or removable. Permanent bollards are often used in places that require a high level of security, while removable bollards are used in places that require only occasional protection. Bollards are an effective and aesthetically pleasing way of providing security, traffic control, and pedestrian safety.

A landowner and a contractor entered into a written contract under which the contractor agreed to build a building and pave an adjacent sidewalk for the landowner at a price of $55,000. Later, while construction was proceeding, the landowner and the contractor entered into an oral modification under which the contractor was not obligated to pave the sidewalk, but still would be entitled to $55,000 upon completion. The contractor completed the building. The landowner, after discussions with his attorney, demanded that the contractor pave the adjacent sidewalk. The contractor refused.Has the contractor breached the contract?

Answers

Yes, the contractor has breached the contract.

What is the contract about?

While the original written contract required the contractor to build a building and pave an adjacent sidewalk for the landowner at a price of $55,000, the subsequent oral modification eliminated the obligation to pave the sidewalk, but did not change the price.

However, the landowner's demand to pave the sidewalk indicates that he did not agree to the modification, or that the modification was not clear and unequivocal. Therefore, the original written contract remained in effect, and the contractor was obligated to pave the sidewalk. By refusing to do so, the contractor breached the contract.

Exercise 15 Write a function select of this type: 'a list ('a -> bool) -> 'a list that takes a list and a function fas parameters. Your function should applyf to each element of the list and should return a new list containing only those elements of the original list for which f returned true. (The elements of the new list may be given in any order.) For example, evaluating select ([1,2,3,4,5,6,7,8,9,10), is Prime) should result in a list like [7,5, 3,2]. This is an example of a higher-order function, since it takes another function as a parameter. We will see much more about higher-order functions in Chapter 9

Answers

An ordered group of values is a list. The components of a list are referred to as its elements or items. The terms element and item will both refer to the same object. Strings are ordered collections of characters.

The syntax for gaining access to a list's items is the same as the grammar for gaining access to a string's characters. The index operator is employed ( [] – not to be confused with an empty list). append() adds the element to the list's end. The element is inserted prior to the specified index using insert(). extend() adds items from the iterable to the list, extending it. Concatenating multiple lists to generate a single new list is possible with the + operator. Lists are arranged groups of objects that make it simple to use a set of data in Python. List items are entered between square brackets [] and are spaced out with commas. It is best to leave a blank space between the comma and the next value.

ESTION ONE a) List five (5) basic units of quintiles. p) State two examples of base and derived units e) State Newton's first law of motions. 1) Convert the following to their respective units 270 j to kilojoules i.

Answers

The five basic units of quantities may include length, mass, time, electric current, and the amount of substance. Each one of them is measured in its respective units.

What are the two examples of base and derived units?

A base unit is the most elementary unit in the system of measurement. For example, an inch is a unit of length, and a meter is also a unit of length. Derived units are those units that are obtained as a result of a process in which more than one base unit is manipulated with derived units between each other. Pressure, mass, and current density are examples of derived units.

Newton's first law of motion states that a body or any other object that remains at rest or uniform motion will continue to be at rest or uniform motion until and unless a net external force applies over it.

The conversion of 270 j to kilojoules is as follows:

1 KJ = 1000 J

270 J = 270/1000 = 0.27 KJ.

A normally consolidated clay specimen (φ=31°) was consolidated under a chamber-confining pressure of 132kN/m. Failure of the specimen was caused by an added axial stress of 158.1 kN/m2 in an undrained condition. Determine φα" At and the pore water pressure in the specimen at failure

Answers

φα" = arctan[(σa'-σ'v)/(2τv)] = arctan[(158.1-132)/(2*132)] = 6.5°

The pore water pressure at failure is equal to the increase in axial stress, which is 158.1 kN/m2.

Given:

φ = 31°Chamber-confining pressure (σ'v) = 132 kN/m2Axial stress at failure (σa') = 158.1 kN/m2

To determine the angle of internal friction (φα") and pore water pressure at failure, we can use the following equations:

φα" = arctan[(σa'-σ'v)/(2τv)]

Pore water pressure (u) = σa' - σ'v

where τv is the effective vertical stress, which is equal to σ'v in this case, since the specimen is normally consolidated.

Substituting the given values into the equation for φα", we get:

φα" = arctan[(158.1 - 132)/(2*132)] = 6.5°

Therefore, the angle of internal friction at failure is 6.5°.

Substituting the given values into the equation for pore water pressure, we get:

Pore water pressure (u) = 158.1 - 132 = 26.1 kN/m2

Therefore, the pore water pressure at failure is 26.1 kN/m2.
