How can a reluctance motor run at a synchronous speed?
A reluctance motor can run at a synchronous speed by aligning the rotor poles with the stator poles when there is no load present.
Reluctance motor can run at synchronous speed by proper alignment of the rotor poles with the stator poles. If no load is there, the rotor poles move to the position of maximum reluctance in respect to the stator poles. As a result, the rotor poles position themselves with respect to the stator poles.When a load is applied, the rotor poles are out of the initial position, and this movement causes the reluctance torque to occur. This helps in the alignment of the poles, thereby reducing the error between the rotor and stator poles, resulting in the motor running at synchronous speed. Therefore, to keep the rotor at synchronous speed, the stator must provide the required current to the motor's winding.Furthermore, the reluctance motor is very energy-efficient and can be employed in many different applications. Its efficiency is higher in the region between no load and full load.
In conclusion, reluctance motor can run at a synchronous speed by proper alignment of the rotor poles with the stator poles.

The force exerted by the 25 mm diameter jet against the fixed vertical wall is approximately 624.36 Newtons.
To determine the force exerted by the jet against a fixed vertical wall, we can use the principle of conservation of momentum. The force exerted by the jet is equal to the change in momentum per unit time.
First, let's calculate the velocity of the jet using the discharge rate and the diameter of the jet. The cross-sectional area of the jet can be calculated using the formula for the area of a circle:
[tex]A = πr^2where r is the radius of the jet, which is half of the diameter. Therefore:r = 25 mm / 2 = 0.0125 mA = π(0.0125 m)^2 ≈ 0.0004909 m^2\\[/tex]
The velocity of the jet can be calculated using the equation:
Q = A * V
where Q is the discharge rate and V is the velocity. Rearranging the equation, we have:
V = Q / A
V = 0.025 m^3/s / 0.0004909 m^2 ≈ 50.9 m/s
Now, let's calculate the momentum of the jet per unit time. Momentum is defined as the product of mass and velocity:
m = ρ * V * A
where ρ is the density of the fluid. Assuming the fluid is water, its density is approximately 1000 kg/m^3.
m = 1000 kg/m^3 * 0.025 m^3/s * 0.0004909 m^2 ≈ 12.27 kg/s
The force exerted by the jet against the wall is equal to the rate of change of momentum, which is given by:
F = Δp / Δt
Since the momentum per unit time is constant, the force is simply:
F = m * V
F = 12.27 kg/s * 50.9 m/s ≈ 624.36 N
Therefore, the force exerted by the 25 mm diameter jet against the fixed vertical wall is approximately 624.36 Newtons.

A rectangular channel of bed width of 5.0 m and water depth of 1.5 m. The bed width is gradually expanded to 6.0 m. Determine: i. The discharge if a drop of 30 cm in water levels is noticed within the expansion zone, classify the flow; The discharge if the water level is raised by 10 cm within the contracted zone, classify the flow; For the discharge values obtained in a and b above, find b₂ if y2 = yc; How can you keep the water levels within the contracted zone unchanged? Draw the relationship between b2, y₁, and y2. ii. iii. iv. V.
i. To find the discharge if a drop of 30 cm in water levels is noticed within the expansion zone, we have to use the momentum equation. The given parameters are as follows:
Bed width, B1 = 5.0 mWater depth, y1 = 1.5 mBed width in the expansion zone, B2 = 6.0 mDrop in water level, ∆y = 30 cm = 0.3 mLet Q be the discharge and v1, v2 are the velocities at sections 1 and 2, respectively. Conservation of mass requires Q = v1A1 = v2A2Where A1 and A2 are the cross-sectional areas of the channel at sections 1 and 2. Since the channel is rectangular,v1 = Q/A1 and v2 = Q/A2By applying the momentum equation between sections 1 and 2, we have, Q = ((y1+y2)/2) × B1 × ((y1-y2)/∆t) … (i)Where, y2 = y1 - ∆y = 1.5 - 0.3 = 1.2 m Taking the coefficient of discharge as Cd = 1.0 (for simplicity), the velocity v1 can be calculated as,v1 = Q/A1 = Q/(B1y1)Also, the velocity v2 can be calculated as,v2 = Q/A2 = Q/(B2y2)By substituting the values of v1 and v2 in equation (i), we getQ = B1(y1 - y2)√(2g(y1 + y2)) … (ii)On substituting the values in equation (ii),Q = 5.0(1.5 - 1.2) √(2 × 9.81 × (1.5 + 1.2))= 1.107 m³/sAs the water level drops within the expansion zone, the flow will be a gradually varied flow.ii. To find the discharge if the water level is raised by 10 cm within the contracted zone, we have to use the energy equation. The given parameters are as follows:Bed width in the contracted zone, B1 = 5.0 m Water depth in the contracted zone, y1 = 1.5 mRaised water level in the contracted zone, ∆y = 10 cm = 0.1 mLet Q be the discharge and v1 is the velocity at section 1. Conservation of mass requires,Q = v1A1Where A1 is the cross-sectional area of the channel at section 1. Since the channel is rectangular,v1 = Q/A1By applying the energy equation between sections 1 and 2, we have, Q = A1 × v1 × √(2g(y2-y1+∆y)) … (iii)Taking the coefficient of the discharge as Cd = 1.0 (for simplicity), the velocity v1 can be calculated as,v1 = Q/A1 = Q/(B1y1)On substituting the values in equation (iii),Q = (B1y1) √(2g(y2-y1+∆y)) … (iv)On rearranging equation (iv), we get,y2 = y1 - ∆y + (Q²/2gB₁²y₁³) … (v)On substituting the values in equation (v),y2 = 1.5 - 0.1 + ((1.107)²/2×9.81×5.0²×1.5³) = 1.374 mAs the water level is raised within the contracted zone, the flow will be a rapidly varied flow. i. The discharge Q is found to be 1.107 m³/s. As the water level drops within the expansion zone, the flow will be a gradually varied flow.ii. The discharge Q is found to be 1.107 m³/s and the water level y2 is found to be 1.374 m. As the water level is raised within the contracted zone, the flow will be a rapidly varied flow.iii. For the discharge values obtained in (i) and (ii), we have,Q = v2A2 = v1A1 = (Q/B1y1)B1y1By applying Chezy’s equation, we get, v1 = C √(RS),v2 = C √(R'S')Where C is the Chezy’s coefficient, R is the hydraulic radius and S is the bed slope. Since the bed slope is not given, we can assume that the bed slope is same throughout the channel.Rearranging the above equations, we get,Q = C (R'B2y2/B1y1) √((R'B2y2/B1y1)(y2-y1)/∆x) … (vi)On substituting the values in equation (vi),1.107 = C (6.0 × 1.374/5.0 × 1.5) √((6.0 × 1.374/5.0 × 1.5)(1.374-1.5)/∆x)On solving the above equation,∆x = 97.16 miv.
To keep the water levels within the contracted zone unchanged, the discharge Q should remain constant. This can be achieved by adjusting the channel slope and width. By increasing the channel slope, the velocity increases which increases the discharge. By decreasing the channel width, the discharge decreases which keeps the water levels within the contracted zone unchanged.v. The relationship between b2, y₁, and y2 is given by,B2y2 = B1y1 + b2(y2-y1)On substituting the values in the above equation,6.0 × 1.374 = 5.0 × 1.5 + b2(1.374-1.5)On solving the above equation, we get,b2 = 3.17 m.

Consider a paging system where the page table is stored in the translation look aside buffer (TLB). The hit ratio is 99% meaning the page table entry will be found in TLB 99% of the time. The normal memory access time is t= 1.7 microseconds whereas TLB access is 0.1 microseconds. a. When calculating the effective paged memory access time, why is the cost of a TLB miss the sum of TLB access time plus normal memory access time? b. If we consider only swap-in/swap-out time and if swap-in-time = swap-out-time = 18 milliseconds, and, on the average, 85% of the pages are dirty, what is the effective page fault service time? 0,85 (2.18) + 0,15 (18) c. If we consider only memory and TLB access time what is the effective access time? 0.94 (1₁7)· (0.01) (2.1.7) + 0.1
the effective access time can be calculated as follows:
Effective access time = 0.99 × 0.1 + 0.01 × 1.8 = 0.108 microseconds = 1.08 x 10^-7 seconds (rounded to 3 decimal places).Hence, the effective access time is 1.08 x 10^-7 seconds.
a. The cost of a TLB miss is the sum of TLB access time plus normal memory access time because it involves two memory accesses. When the TLB misses a translation, the operating system has to access the page table to look for the required translation, which adds an additional time of normal memory access.
b. The formula for calculating effective page fault service time is as follows:
Effective page fault service time = (1-p) × memory access time + p × (swap page time + memory access time)
where p is the page fault rate and (1-p) is the hit rate.
memory access time = 1.7 microsecondsswap page time = 18 milliseconds = 18,000 microseconds
Given that 85% of the pages are dirty, the page fault rate is 0.85. Therefore, the effective page fault service time can be calculated as follows:
Effective page fault service time = (1-0.85) × 1.7 + 0.85 × (18,000 + 1.7) = 2,900.5 microsecondsc. The formula for calculating effective access time is as follows:
Effective access time = hit ratio × time taken for hit + (1 - hit ratio) × time taken for miss
Where hit ratio is 0.99,time taken for hit = TLB access time = 0.1 microseconds
time taken for miss = TLB access time + normal memory access time = 0.1 + 1.7 = 1.8 microseconds
Therefore, the effective access time can be calculated as follows:
Effective access time = 0.99 × 0.1 + 0.01 × 1.8 = 0.108 microseconds = 1.08 x 10^-7 seconds (rounded to 3 decimal places).Hence, the effective access time is 1.08 x 10^-7 seconds.

The thickness of the footing is 0.38 m, and the footing's bottom is 1.9 m below the ground surface. The gross allowable bearing pressure is 197 kPa. We will calculate the actual critical shear acting on the footing in kN using the given data.
Dead load = 132 KN/m Live load = 254 KN/m
My concrete = 24 KN/m³Y soil = 18 KN/m³Depth of top of the footing to NGL = 1 m
Concrete cover => 75mmAssume db = 16mm dia.
So, we'll start by determining the maximum allowable load that can be supported by the footing. From the given information, the net ultimate bearing capacity of the soil is obtained.
Net ultimate bearing capacity of soil = Gross allowable bearing pressure/FS (factor of safety)For a small structure, an FS of 3 is used. The net ultimate bearing capacity of soil is obtained by dividing the gross allowable bearing pressure by three.
Net ultimate bearing capacities of soil = 197 kPa/3 = 65.67 kPa
The maximum allowable load per unit area is calculated as follows:
Maximum allowable load per unit area = Net ultimate bearing capacity of soil x footing area
Maximum allowable load per unit area = 65.67 kPa x 1.3 m
Maximum allowable load per unit area = 85.471 kN/m²The actual load per unit area is calculated as follows:
Actual load per unit area = Dead load + Live load
Actual load per unit area = (132 KN/m + 254 KN/m)Actual load per unit area = 386 KN/m
The load intensity is determined by dividing the actual load per unit area by the footing width.
Load intensity = Actual load per unit area/footing width
Load intensity = 386 KN/m/1.3 m
Load intensity = 297.87 kN/m²
The critical shear is determined by the following formula:
Critical shear = 0.33 x maximum allowable load per unit area x footing width
Critical shear = 0.33 x 85.471 kN/m² x 1.3 m
Critical shear = 36.02 kN/m

The air fryer won't work if component QK fails. Current component QK's reliability is 0.95. Every other part of the appliance is 100 percent reliable. What is the reliability of the air fryer if you added a backup QK which had a reliability of .90? .9975 .995 .90 .9025 .95
The reliability of the air fryer after adding a backup QK with a reliability of .90 is 0.855 or 85.5%.Therefore, the correct answer is 0.855.
The reliability of the air fryer after adding a backup QK with a reliability of .90 can be calculated as follows:First, we find the probability that component QK fails, which is 1 - 0.95 = 0.05. Therefore, the probability that component QK does not fail is 0.95.The probability that the backup QK will fail is 1 - 0.90 = 0.10. Therefore, the probability that the backup QK will not fail is 0.90.Since we have two components in parallel, the probability that the air fryer will work is the probability that both QK and the backup QK will not fail. This can be calculated using the formula:P(A and B) = P(A) x P(B)where A and B are independent events.The probability that the air fryer will work is therefore:0.95 x 0.90 = 0.855.

c) Reciprocating screw is used
d) both b and c
Injection molding is a manufacturing process where molten plastic is injected into a mold, cooled, and then ejected as a finished product. This is used for the mass production of parts that are uniform and complex in shape.
The choice for the type of mold to be used depends on the part's complexity, the materials, the required volume, and the production time.Based on the given options, the true statement about injection molding is that d) both b and c are true. Molten plastic is injected into the mold at intervals (non-continuous), and a reciprocating screw is used. The molten plastic is transferred into the injection cylinder through the hopper.
In the injection cylinder, the reciprocating screw transports the plastic pellets forward and heats them to a molten state. After that, the screw injects the molten plastic into the mold. During the injection stage, the screw moves back to its original position and waits for the next shot to be injected. This means that the plastic is not continuously injected, but instead in intervals. The reciprocating screw is used to transport the plastic forward and melt it to a molten state.

Write a program in assembly language (8086):
1-prompt the user to input (E) to encrypt or (D) to decrypt, any other character will be responded with (that is an illegal character please try again). store it in x3100
2-prompt the user to input the encryption key (a single digit from 1-9), store it in x3101, and use it for enc and dec.
3-prompt the user to input a message no more than 20 character (when done, press enter to terminate the message), the program will store the message starting in location x3102, you must reserve locations x3102 to x3116 to store the message (21 locations, the enter key included).
Hint: to continually read from the keyboard without first printing a prompt on the screen, use the appropriate interrupt (such as INT 21). That is for each key you wish to read, the EMU8086 operating system must execute this interrupt service routine. Don't forget to follow input interrupt with the instruction for interrupt for output, the character the user types will be displayed on the screen.
Your program should output the encrypted or decrypted message to the screen. Note that the encryption/decryption algorithm stored the message to be output starting in the location.
Use MASM assembler to create your segments, constants, variables and others.
The user can select one operation from a list of items (menu numbered 0, 1, 2)

Given the following. double *ptr = new double[47]; assuming new returns the address 13000. What is the value of ptr+1;
The value of ptr+1 is 13008. When a new pointer is created, it allocates memory on the heap. When an array is allocated, the new expression returns a pointer to the first element of the array.
Here, the new expression allocates memory for an array of 47 doubles and returns a pointer to the first element of the array. The first element's address is 13000, and since each double is 8 bytes long, the address of the next double in the array is 13008. As a result, ptr+1's value is 13008.
In this problem, we are using a dynamic array of 47 doubles and then attempting to obtain the address of the second double. To allocate memory on the heap, we use the new operator. It returns the address of the memory block allocated in the heap. We use a double pointer to keep track of the memory address where the first double element is stored, and we allocate memory for 47 double elements by using the following statement. double *ptr = new double[47]; This line of code allocates memory for 47 doubles in the heap and assigns the address of the first element to ptr. Here, ptr will point to the first element of the array.
If we add one to ptr, we'll get the address of the next double. We are incrementing ptr by one, which means that ptr+1 will point to the address of the second element of the array. Therefore, the value of ptr+1 is 13008, the address of the next double after the one ptr currently points to.
The value of ptr+1 is 13008 because the first double element's address is 13000, and each double element in the array is eight bytes long. As a result, the next double's address in the array is 13008. Therefore, by incrementing the pointer by one, we can obtain the address of the next double in the array.

Time t = 0) is the starting point immediately after the two smaller rods are joined. Solve the Heat Equation for the combined rod where assuming that the ends are insulated (i.e., that dulax=0 when 2 = 0 and 2 =2), and that the constant of proportionality is k = 4.
The value of heat equation is u(x,t) = Σn=1∞{An sin(πn x/2)exp[-(πn)2t]}.The boundary conditions give X'(0) = 0 = X'(2).
Heat Equation.The Heat Equation is a linear, homogeneous partial differential equation that describes how heat energy flows through a given medium.
It also describes diffusion or how solutes spread through a given medium, depending on how the problem is set up. The equation is defined as: ut = c2uxx.
The general solution to this equation is u(x,t) = Σk=0∞{Akcos(kπx)exp[-(kπ)2c2t]} where A0, A1, A2, ..., are constants.
Heat Equation SolutionGiven, u(s, t) be the temperature on the rod (i.e., the 2m long rod obtained by joining the two 1m rods together) at the point x and time t. So 0 << < 2 and t > 0.Time t = 0) is the starting point immediately after the two smaller rods are joined.
Solve the Heat Equation for the combined rod where assuming that the ends are insulated (i.e., that dulax=0 when 2 = 0 and 2 =2), and that the constant of proportionality is k = 4.
So, we have the Heat Equation, ut = c2uxx. Here, c2 = k = 4. So, the equation is ut = 4uxx.
This Heat Equation is a standard PDE that can be solved using the Separation of Variables Method.Let u(x,t) = X(x)T(t). Then, ut = T'X and uxx = X''T.
Thus, we have T'X = 4X''T => T'/T = 4X''/X = λ, where λ is a constant.Now, we have two ODEs: T'/T = λ and X'' - λ/4 X = 0.
Applying the boundary conditions of insulated ends gives X'(0) = 0 = X'(2).
Thus, X(x) = Asin(πn x/2) where n = 1,2,3,...Substituting this in the ODE for X(x), we get λ = -(πn/2)2. Thus, Xn(x) = sin(πn x/2) and λn = -(πn/2)2.Now, we need to find T(t). T' = λT => Tn(t) = exp(-λn t).
u(x,t) = Σn=1∞{An sin(πn x/2)exp[-(πn)2t]}.
The boundary conditions give X'(0) = 0 = X'(2).
This condition implies πn/2 = kπ for some k, which means n is even.
Thus, the series reduces to:u(x,t) = Σn=1∞{An sin(πn x/2)exp[-(πn)2t]} = A2sin(πx/2)exp[-(π2)t] + A4sin(2πx/2)exp[-(2π)2t] + A6sin(3πx/2)exp[-(3π)2t] + ...
Now, we need to find the An coefficients using the initial condition, which is given as: u(x,0) = f(x) = x(2-x). Thus, A2 = 2.49, A4 = 0.98, A6 = 0.51, and so on.
Finally, we can write the solution to the Heat Equation as: u(x,t) = 2.49sin(πx/2)exp[-(π2)t] + 0.98sin(2πx/2)exp[-(2π)2t] + 0.51sin(3πx/2)exp[-(3π)2t] + ...
The heat equation is a partial differential equation that describes how heat energy flows through a medium.
The equation is ut = c2uxx, where c2 is a constant of proportionality.
Given the temperature on a 2m long rod, u(s, t), we can solve the heat equation using the Separation of Variables Method. Assuming that the ends of the rod are insulated and that k = 4, we get ut = 4uxx as the Heat Equation.
Applying the boundary conditions of insulated ends gives us Xn(x) = sin(πn x/2) and λn = -(πn/2)2. Thus, the solution to the Heat Equation is u(x,t) = Σn=1∞{An sin(πn x/2)exp[-(πn)2t]}.
Using the initial condition, u(x,0) = f(x) = x(2-x),
we can find the coefficients An and simplify the series to u(x,t) = 2.49sin(πx/2)exp[-(π2)t] + 0.98sin(2πx/2)exp[-(2π)2t] + 0.51sin(3πx/2)exp[-(3π)2t] + ...

A 120-V, 6.00-kW compound generator has armature resistance of 60 milli-ohm, series-field resistance of 36 milli-ohm, and shunt-field resistance of 30-ohm. When the generator is connected as a short-shunt, calculate: () The load current (IL): [A] (ii) The voltage accross the shunt field winding (Vf): [V] (ii) The current in the shunt field winding (if): [A] (iv) The armature current (la): [A] (v) The current in the series field winding (Is): [A] (vi) The induced emf (Ea): [V] If the rotational loss is 800-W, determine: (vii) The copper loses due to the armature resistance: [W] (viii) The copper loses due to the shunt field resistance: [W] (ix) The copper loses due to the series field resistance: [W] (x) The power developed (Pd): [W] (xi) The input power (Pin): [W] (xii) The efficiency of the generator (Eta): [%] W
To maintain the same flux and power developed by the machine, the reconnected short-shunt compound generator needs to make certain adjustments, namely: Increase in the shunt field current Decrease in the series field current Increase in the shunt field resistance Decrease in the series field resistanceReason.
The generator is rated at 50 kW, 250 V, and 600 rpm. In long-shunt compound generator connection, field diverter resistance is used, and it delivers the rated load at rated voltage. The machine is reconnected as a short-shunt compound generator, and it is assumed that it delivers the rated load at rated voltage. As the flux remains the same in the short-shunt generator, the number of turns in the shunt field winding must be constant. In the case of a short-shunt compound generator, the flux of the machine is always the same as it was before, which means that the change in current through the shunt field is due to the change in shunt field resistance. A 120 V, 6.00 kW compound generator has armature resistance of 60 milli-ohm, series-field resistance of 36 milli-ohm, and shunt-field resistance of 30-ohm.
When the generator is connected as a short-shunt, the calculation is as follows:
Load current (IL) = (P/V) = (6000/120) = 50A
The voltage across the shunt field winding (Vf) = 120V
The current in the shunt field winding (if) = Vf/Rf = 120/30 = 4A
The armature current (la) = IL + If = 54A
The current in the series field winding (Is) = IL/ns = 50/2 = 25A
Induced emf (Ea) = V + IaRa = 120 + (54 × 0.06) = 123.24V
Copper losses due to the armature resistance = la2Ra = 54 × 0.06 = 3.24 W
Copper losses due to the shunt field resistance = if2Rf = 4 × 4 × 30 = 480 W
Copper losses due to the series field resistance = Is2Rs = 25 × 25 × 36 × 10-3 = 22.5 WPd = VIa = 120 × 54 = 6,480 WPin = Pd + copper losses + rotational losses = 6,480 + 3.24 + 480 + 22.5 + 800 = 7,785.74
WEta = (Pd/Pin) × 100% = (6,480/7,785.74) × 100% = 83.20%
Hence, the load current is 50 A, the voltage across the shunt field winding is 120 V, the current in the shunt field winding is 4 A, the armature current is 54 A, the current in the series field winding is 25 A, the induced emf is 123.24 V, the copper losses due to the armature resistance are 3.24 W, the copper losses due to the shunt field resistance are 480 W, the copper losses due to the series field resistance are 22.5 W, the power developed is 6,480 W, the input power is 7,785.74 W, and the efficiency of the generator is 83.20%.

Pa.s: t=1s )
The answer is: Given, The volume of effluent flown from the aeration stage = 200 MLD
Velocity gradient = 800 [tex]s^-1[/tex]
Dynamic viscosity = 1.06 × [tex]10^-3[/tex]Pa.s Time taken = 1 s
Formula used is, V = Q /A where,V is the volume, Q is the flow rate, and A is the area of cross-section of the flow. Volume,
V = (200 x [tex]10^6[/tex]) / (24 x 60 x 60)
= 2314.81 [tex]m^3[/tex]/s Velocity gradient, G = 800 [tex]s^-1[/tex] Dynamic viscosity,
μ = 1.06 × [tex]10^-3[/tex] Pa. sTime taken,t = 1 s We know that, the power,
P = (μ x [tex]G^2[/tex] x V) / t
The power value for gradient velocity at 800 [tex]s^-1[/tex] is:
P = (1.06 ×[tex]10^-3[/tex] x [tex]800^2[/tex] x 2314.81) / 1= 1.77 kW
The range of velocity gradient required for maintaining a sweep coagulation reaction is between 500 to 2000 [tex]s^-1[/tex].The power required for this removal mechanism is between 0.5 to 2.5 kW.

Describe the PEAS description of the task environment and characterize it in terms of the properties
1 - an automatic garbage collector robot
2 - a StarCraft II game agent that can compete with human players
PEAS stands for Performance measure, Environment, Actuators and Sensors. PEAS is an acronym used in Artificial Intelligence that stands for the four crucial elements of an agent's task specification that are the Performance measure, Environment, Actuators, and Sensors.
This approach helps in designing an intelligent system based on the analysis of the tasks an agent is required to perform. Here's how to describe the PEAS description of the task environment and characterize it in terms of the properties for the given tasks:1. An automatic garbage collector robotThe automatic garbage collector robot is a task environment that has a Performance measure that can be defined as the amount of garbage collected from the environment. The garbage collector robot works in an environment where it has to collect the garbage.
The Actuators and Sensors of the robot include arms and sensors to detect the location of garbage in the environment.The properties of the environment in which the garbage collector robot works include the presence of garbage in the environment and the amount of garbage to be collected. The properties of actuators and sensors are related to the movement of the robot to collect the garbage.2. A StarCraft II game agent that can compete with human playersA StarCraft II game agent is an environment that has a Performance measure, which can be defined as the success of the game agent in winning the game against human players.
