Distance divided by propagation speed = m/s meters/sec . The propagation delay is equal to d/s, where d is the distance and s is the speed at which the wave propagates.
What is the formula for propagation delay (dprop)?The speed of light, or s=c, is used in wireless communication.
The propagation delay is the time it takes for a signal to reach its destination after it has been sent; The length of time it takes for the signal to travel through a medium is what causes it.
The speed at which the packet travels is equal to the speed of light multiplied by the text velocity factor multiplied by the small text speed of light multiplied by the speed of light multiplied by the text velocity factor. As a result, the propagation delay is the amount of time it takes for the last bit of a packet to reach its destination.

what is boundary shear stress? what is the critical shear stress to move sediment? how are these related to initiate sediment movement?
- Boundary Shear Stress: identifies near-bed sediment transport conditions - Critical shear stress: the lowest shear stress necessary to move sediment - Critical shear stress at the boundary that will cause a sizable number of particles to move.
Boundary shear stress: what is it?
The tangential part of the hydrodynamic forces moving over the channel bed is called boundary shear stress. The boundary shear force distribution throughout the channel's wetted perimeter directly affects the flow characteristics of open channels.
What shear stress is necessary to move sediment?
The amount of shear required to move sediments delivered to the channel is known as the critical shear stress. The channel will probably be in equilibrium when the shear stress reaches the critical shear stress. Channel deterioration is likely to happen when shear stress is substantially higher than the critical shear stress.
How do these relate to start moving sediment?
The threshold at which sediment particles begin to move in open-channel flow is known as the "initiation of motion." In channel design, this threshold is crucial to ensure sediment mobility and prevent obstruction. In order to avoid clogging, the Froude number F = 0.08 has frequently been used as the minimal value.

what is the relative resolution (i.e. how many discrete levels are there) of an oscilloscope with 2^n, 8-bit D/A converter has 256 levels, 12-bit D/A converter has 4096 levels and 16-bit converter has 65536 levels.
In the system development and prototyping phases, oscilloscopes are of course the preferred tool for doing these measurements, but these are principally constrained by the vertical resolution of the scope's front-end. For instance, an 8-bit oscilloscope has a dynamic range of 256:1, therefore the theoretically lowest signal on a range of 1 volts is 3.9 millivolts (mV). Higher sensitivity and offset range are required to view millivolt level ripple signals on a 3.3 volt bus. Additionally, signal levels at the scope input will be muted when employing high attenuation probes to prevent circuit loading, making it difficult to measure them unless the instrument has a high resolution.
The ratio of the largest input signal an oscilloscope can handle to the smallest signal amplitude it can detect is known as oscilloscope vertical resolution. Resolution is often measured by the analog-to-digital converter's bit count (ADC). The resolution is equal to the amount of bits multiplied by two. The resolution of an 8-bit converter is therefore 28 or 256:1. The resolution of a 12-bit converter is 4096:1, which is 16 times higher than that of an 8-bit converter.

Pebbling a checkerboard. We are given a checkerboard which has 4 rows and n columns, and has an integer written in each square. We are also given a set of 2n pebbles, and we want to place some or all of these on the checkerboard (each pebble can be placed on exactly one square) so as to maximize the sum of the integers in the squares that are covered by pebbles. There is one constraint: for a placement of pebbles to be legal, no two of them can be on horizontally or vertically adjacent squares (diagonal adjacency is fine). (a) Determine the number of legal patterns that can occur in any column (in isolation, ignoring the pebbles in adjacent columns) and describe these patterns. Call two patterns compatible if they can be placed on adjacent columns to form a legal placement. Let us consider subproblems consisting of the first k columns 1 ? k ? n. Each subproblem can be assigned a type, which is the pattern occurring in the last column. (b) Using the notions of compatibility and type, give an O(n)-time dynamic programming algorithm for computing an optimal placement
(a) The number of legal patterns that can occur in a single column is 3. The 3 patterns are:
2 pebbles placed on the top 2 rows.
2 pebbles placed on the bottom 2 rows.
1 pebble placed on the top row and 1 pebble placed on the bottom row.
These patterns are not compatible with each other, meaning that two columns cannot both have the same pattern.
(b) To solve the problem, we can use a dynamic programming algorithm. The idea is to keep track of the maximum sum that can be obtained from each subproblem with a specific type, and use this information to compute the maximum sum for the next subproblem.
Let's define f[k][i] to be the maximum sum that can be obtained from the first k columns with the last column being of type i.

For k = 0, set f[0][i] = the sum of the integers in the squares covered by the i-th pattern in the first column.
For k = 1, 2, ..., n-1, do the following:
For each type i, compute the maximum sum that can be obtained from the first k columns with the last column being of type i.
f[k][i] = the maximum of f[k-1][j] + the sum of the integers in the squares covered by the i-th pattern in the (k+1)-th column, where j is any type that is compatible with type i.
The maximum sum that can be obtained from the first n columns is the maximum of f[n-1][i], where i is any type.
The time complexity of this algorithm is O(n), since each iteration of the outer loop takes O(1) time and there are O(n) iterations.

how to the linear thermal expansion coefficients for steel, copper and aluminium compare ? fundamentally what are the differences occuring at the atomic level to cause the difference ? g
Since the linear expansion for steel, copper, and aluminum. Thus, the value of copper is lower than that of alum and lower than that of steel. Therefore, we might conclude that the steel expands less.
What is the thermal expansion coefficient of copper and aluminum?Copper and aluminum have the following thermal linear coefficients of expansion per degree centigrade: 17 10E-6 copper. 2310E-6 aluminum.
Which expands more, steel or aluminum?A steel panel that is 100' long and is subjected to a temperature change of 100°F will lengthen by 0.78", whereas an aluminum panel of the same length and subjected to the same temperature change will lengthen by 1.56".
