Off the southern coast of Andorra in the Mediterranean Sea lies the island of Duosomata (pronounced DOO-oh-so-MAH-ta). It is populated exclusively by short people and tall people. No people of average height live on the island. We can use the following predicates to say things about the people of Duosomata.
person(x)
≡
x is a person.
short(x)
≡
Person x is short.
tall(x)
≡
Person x is tall.
taller(x, y)
≡
Person x is taller than person y.
Answer the following questions by writing expressions in predicate calculus that use these predicates. Assume that quantified variables range over all possible objects, not just people, and not just people from Duosomata.
1a. (5 points.) Write an expression that means ‘‘If there are any two people, and the first person is taller than the second person, then the first person is tall, and the second person is short.’’
1b. (5 points.) Write an expression that means ‘‘At least one tall person is taller than any short person.’’
1c. (10 points.) Suppose that this is true:
¬ ∃s ∃t [person(s) ∧ person(t) ∧ short(s) ∧ tall(t) ∧ taller(s, t)]
Then prove that this is true:
∀s ∀t [(person(s) ∧ person(t) ∧ short(s) ∧ tall(t)) → ¬ taller(s, t)]
Your proof must be written as a series of steps. Each step must be an expression in predicate calculus. You must give a reason for each step.
1a. (∀x)(∀y)((person(x) ∧ person(y) ∧ taller(x, y)) → (tall(x) ∧ short(y)))
1b. (∃x)(tall(x) ∧ (∀y)(short(y) → taller(x, y)))
How can we show the proof?1c.
Proof:
Step 1:
Assume (person(s) ∧ person(t) ∧ short(s) ∧ tall(t))
Step 2:
From Step 1, we know that (person(s) ∧ person(t) ∧ short(s) ∧ tall(t)) is true.
Step 3:
Assume ¬ taller(s, t) is false, i.e. taller(s, t) is true.
Step 4:
From Step 3, taller(s, t) is true, which contradicts the assumption in (1c) that ¬ ∃s ∃t [person(s) ∧ person(t) ∧ short(s) ∧ tall(t) ∧ taller(s, t)].
Step 5:
From Step 4, it follows that ¬ taller(s, t) must be true, i.e. (person(s) ∧ person(t) ∧ short(s) ∧ tall(t)) → ¬ taller(s, t) is true.
Step 6:
Since Step 5 holds for any s and t that satisfy (person(s) ∧ person(t) ∧ short(s) ∧ tall(t)), it follows that
(∀s)(∀t)((person(s) ∧ person(t) ∧ short(s) ∧ tall(t)) → ¬ taller(s, t)) is true.

In the direction from A to E, the force created along the antenna at point A is roughly 1998 lb.
Where is the stress at its highest?The tension in the string is largest at the mean position and minimal at the extreme position for a simple oscillating pendulum.
We can apply the method of sections to calculate the maximum tension in cable AD. A slice through cables AB and AD reveals the following:
Sum of vertical forces = 0
T_AD*sin(60) - T_AB = 0
T_AD = T_AB/sin(60) = T_AB/0.866
Taking a section through cables AC and AD, we have:
Sum of vertical forces = 0
T_AD*sin(60) - T_AC = 0
T_AD = T_AC/sin(60) = T_AC/0.866
Since the tension in either cable AB or AC cannot exceed 1000 lb, the maximum tension that can be developed in cable AD is:
T_AD = 1000/0.866 = 1154 lb (rounded to the nearest lb)
To determine the force developed along the antenna at point A, we can use the method of joints. Taking joint A, we have:
Sum of horizontal forces = 0
F_AEcos(30) + T_ADcos(60) = 0
F_AE = -T_ADcos(60)/cos(30) = -T_ADsqrt(3) = -1998 lb (rounded to the nearest lb, assuming T_AD = 1154 lb)

The output of the system is c(s)=15/s(s+15) = 15/(s^2 + 15s) = 15/(s(s+15)) = 15/s + 1/s+15. The time constant is 15, the rise time is 0.35 and the settling time is 0.70.
Time Constant: 1/15 = 15
Rise Time: 0.35 * 15 = 5.25
Settling Time: 0.70 * 15 = 10.5
The output of the system is c(s)=15/s(s+15). This can be expanded by factoring out a common factor 15/s, resulting in 15/s(s+15) = 15/s + 1/s+15. The time constant is the reciprocal of the coefficient of the s term, or 15. This is the time it takes for the output to reach 63.2% of its final value. The rise time is the time it takes for the output to reach its final value, or 0.35 times the time constant. The settling time is the time it takes for the output to stay within 5% of its final value, and is 0.70 times the time constant.

Consider the Cats and Mice problem: Three cats and three mice wish to cross from the left side to the right side of the river using a single boat. The boat can only hold two animals and can be rowed by any animal in the group. The goal is to find a sequence of moves that transfers all six animals to the right hand side of the river. At no time can the cats outnumber the mice on either side of the river. Your task is to formulate this as a search problem.
(6 pts) List all the heuristics below that are admissible:
(1) h1(n) = number of animals on the left bank
(2) h2(n) = number of animals on the left bank − 1
(3) h3(n) = h ∗ (n) (i.e., the true remaining path cost)

Likewise for n=3, h (3) =h(3)-10=-85-10=-95 and so forth. the TV show we watch; -75, -85,-95, This is a set of arithmetic operations where the common difference (d) equals 10. Since, -85-(-75) =-85+75=-10 {, } 95-(85)=95+(85)=10, and so forth. Initial term (a) = -75. the following is the Explicit Formula for Arithmetic Sequence: a {1} =a+(n-1) d where the first term is a, The frequent distinction is d, and The number of terms is n. We have to find the explicit formula for h(n); Substitute the given values we have; h(n)=-75+(n-1) (-10) or h(n)-75-10 n+10=-65-10 n Therefore, the explicit formula for h(n) is, -65-10 n, h(n)=a+(n-1) d.

consider a hollow spherical shell with uniform surface charge density. by considering the two small patches at the ends of the thin cones in fig. 1.37, show that the electric field at any point p in the interior of the shell is zero. this then implies that the electric potential (defined in chapter 2) is constant throughout the interior.
The electric field at any point inside the shell is zero, and this implies that the electric potential is constant throughout the interior.
Let's assume that the electric field is non-zero at a point P inside the shell. Then, the electric field lines should pass through the patches at the ends of the cones, as the electric field is perpendicular to the surface of the conductor. But this would mean that there is a component of the electric field tangent to the surface of the conductor, which is not possible, as the electric field at any point on the surface of the conductor is perpendicular to the surface.
Therefore, the electric field at any point inside the shell is zero, and this implies that the electric potential is constant throughout the interior. We can calculate the electric potential by using the formula V = kQ/r, where k is the Coulomb constant, Q is the total charge on the shell, and r is the radius of the shell. As the electric potential is constant throughout the interior, the potential at any point inside the shell would be the same and can be calculated using this formula.

an axial force p is applied to the shaft with thrust bearing shown. the bearing consists of a circular collar a that is bonded to the shaft b. applying a factor of safety of 1.5, determine the maximum axial force p that can be applied to the shaft without exceeding the allowable shear stress along cylindrical surface a or b. (shear failure along surface a would mean that whatever is used to bond the collar to the shaft has failed. shear failure along surface b would mean that the fixture c, which prevents the collar from moving to the right, has failed). both the bonding material and the material from which part c is made have a failure shear stress of 255 mpa.
The maximum axial force that can be applied to the shaft is 382.5 kN.The maximum axial force that can be applied to the shaft is 382.5 kN.
What is the significance of the failure shear stress of 255 MPa for the bonding material and fixture used in the thrust bearing?The failure shear stress of 255 MPa is a critical parameter for the bonding material and fixture used in the thrust bearing. This value represents the maximum shear stress that the material can withstand before it fails, and is an important consideration in designing the thrust bearing to support the applied axial force. If the applied force exceeds the allowable shear stress, the bonding material or fixture may fail, leading to catastrophic failure of the bearing and damage to the shaft or other components. Therefore, it is essential to ensure that the maximum axial force is calculated and limited to a level that does not exceed the failure shear stress of the bonding material or fixture.

for which there is an institutional network connected to the Internet. Suppose that the average object size is 850,000 bits and that the average request rate from the institution’s browsers to the origin servers is 16 requests per second. Also suppose that the amount of time it takes from when the router on the Internet side of the access link forwards an HTTP request until it receives the response is three seconds on average (see Section 2.2.5). Model the total average response time as the sum of the average access delay (that is, the delay from Internet router to institution router) and the average Internet delay.For the average access delay, use Δ/(1 – Δ·β), where Δ is the average time required to send an object over the access link and β is the arrival rate of objects to the access link.Find the total average response time.Now suppose a cache is installed in the institutional LAN. Suppose the miss rate is 0.4. Find the total response time
The total average time required to send an object over the access link and β is the arrival rate of objects to the access link is 3.349 seconds
Elaborating the problem:The average access delay, use δ/(1 − δβ)
where :
δ is the average time required to send an object .
β is the arrival rate of objects to the access link.
a) Total average response time:
δ = 850,000 bits / 16000000 bps = 0.0531 Sec
δβ = 0.053 sec/request × 16 request/sec = 0.848
δ/(1 − δβ) = 0.0531/(1-0.848)
= 0.0531/ 0.152
= 0.349
Total average response time= 0.349+3 = 3.349 Sec
b) Total response time
miss rate =0.4
miss rate + hit rate = 1.0 (100%)
hit rate = 1.0 - 0.4 = 0.6
Since 60% of requests are fulfilled within the institutional Network, the traffic intensity on the access link is reduced by 60%, resulting in an average access delay of 0.0531 / (1-0.349 ×0.848)
= 0.0531/(1-0.2959)
= 0.0531/0.7
= 0.075 seconds
When the cache fulfills the request, which has a probability of 0.6, the response time is nearly zero.
The average response time is 0.075+ 3 seconds.
= 3.075 seconds ( which happens 40 % of the time)
So average response time = 0.6 × 0 sec + 0.4 × 3.075 sec
= 1.23 seconds
Thus the average response time reduced from 3.349 seconds to 1.23 seconds.

Find the linear approximation of the following functions (using Taylor series): (a) e^xu close to equilibrium point x=0,u=1
The correct answer is Using a Taylor series, a number is approximated by a polynomial whose value is extremely close to the value of the number in the vicinity of a given x value: f (x) equals f (a) plus f ′ (a) 1! ( x − a ) + f ′ ′ ( a ) 2 !
Near x=a, the second-order Taylor polynomial approximates f(x) more well than the linear approximation (which is the same as the first-order Taylor polynomial). We may use it to do things like determine the local minimum or maximum of the function f. (x). By utilising the formula L(x) = f(a) + f '(a) (x - a), where f '(a) is the derivative of f(x) at an x = a, one may determine the linear approximation, which is indicated by L(x). The difference between an exact value and an approximation to it is the approximation error in a data value.
