A complex airborne navigating system incorporates a subassembly which unrolls a map of the flight plan synchronously with the movement of the aeroplane. This assembly is bought on very good terms from a subcontractor, but is not always in perfect adjustment
on delivery. The subassemblies can be readjusted on delivery to guarantee accuracy at a cost of Rs. 50 per subassembly. It is not, however, possible to distinguish visually those subassemblies that need adjustment.
Alternatively, the subassemblies can each be tested electronically at a cost of Rs. 10 per subassembly tested. Past experience shows that about 30% of those supplied are defective; the probability of the test indicating a bad adjustment when the subassembly is faulty is 0.8, while the probability that the test indicates a good adjustment when the subassembly is properly adjusted is 0.7. If the adjustment is not made and the subassembly is found to be faulty when the system has its final check, the cost of subsequent rectification will be Rs. 140.
Draw up an appropriate decision tree to show the alternatives open to the purchaser and use it to determine his course of action.
To minimize cost, purchaser should choose to test each subassembly electronically and only readjust the faulty ones, as the expected cost of this option is less than readjusting all or readjusting none.
The problem is to decide whether to readjust all the subassemblies at a cost of Rs. 50 per subassembly or to test each subassembly electronically at a cost of Rs. 10 per subassembly tested. The past experience shows that 30% of the subassemblies are faulty. The probability of the test indicating a bad adjustment when the subassembly is faulty is 0.8, while the probability of the test indicating a good adjustment when the subassembly is properly adjusted is 0.7. If the adjustment is not made and the subassembly is found to be faulty when the system has its final check, the cost of subsequent rectification will be Rs. 140.
The decision tree for this problem can be drawn as follows:
Level 1: Readjust all subassemblies (cost = 50 * number of subassemblies) or test each subassembly (cost = 10 * number of subassemblies)
Level 2 (if readjust all): Final check is passed (no cost) or Final check is failed (cost = 140 * number of failed subassemblies)
Level 2 (if test each): Test result is good (no cost) or Test result is bad (cost = 140 * number of failed subassemblies)
Level 3 (if test result is bad): Subassembly is faulty (cost = 140) or Subassembly is properly adjusted (no cost)
By using the probabilities and costs mentioned in the problem statement, the expected costs for each of the alternatives can be calculated and compared. The alternative with the lower expected cost will be the preferred option.

using the fact that v1 * v2 = v1^t v2, show the dot product of two free vectors does not depend on the choice of frames in which their coordinates are defined.
The dot product of two vectors is a scalar quantity that only depends on the scalar product of the vectors' components, and not on the choice of reference frame.
The dot product of two vectors, v1 and v2, can be written as:
v1 · v2 = |v1||v2|cosθ
where |v1| and |v2| are the magnitudes of the vectors and θ is the angle between them. The dot product is a scalar quantity, which means that its value does not depend on the orientation of the vectors in space.
If we change the reference frame in which the vectors are defined, their coordinates will change, but their magnitude and orientation in space will not. This means that the dot product of the vectors will remain the same, regardless of the choice of frame.
For example, let's say that v1 and v2 have coordinates (a1, b1, c1) and (a2, b2, c2) in a reference frame S. If we change to a different reference frame S', the coordinates of v1 and v2 in this new frame will be (a1', b1', c1') and (a2', b2', c2').
However, using the property v1 * v2 = v1^t v2, where v1^t is the transpose of v1, the dot product can be calculated as:
v1 · v2 = (a1, b1, c1) * (a2, b2, c2) = (a1a2 + b1b2 + c1c2)
This expression shows that the dot product is a scalar that only depends on the scalar product of the vectors' components, and not on the choice of reference frame.
Therefore, we can conclude that the dot product of two free vectors does not depend on the choice of frames in which their coordinates are defined.

There are several types of sensors that can provide an electrical output proportional to a physical variable being measured, including:
Resistance Temperature Detectors (RTDs) - RTDs use the change in resistance of a material with temperature to measure temperature. The most common RTDs use a wire made of platinum, nickel, or copper that has a positive temperature coefficient of resistance.
Thermocouples - Thermocouples use the Seebeck effect, which states that a voltage is generated between two dissimilar metals when a temperature difference exists between the two junctions. This voltage can be used to determine the temperature of one of the junctions.
Strain gauges - Strain gauges use the resistance of a material to measure strain. Strain gauges are typically made of a metal foil, such as nickel, that is bonded to a flexible substrate. As the gauge is subjected to strain, its resistance changes, which can be used to determine the strain.
Linear Variable Differential Transformers (LVDTs) - LVDTs use the principle of electromagnetic induction to measure linear displacement. An LVDT consists of a coil and a core that moves within the coil. The position of the core is proportional to the voltage generated in the coil.
Potentiometers - Potentiometers use the change in resistance of a material with position to measure linear displacement.

For which substrate does the enzyme achieve a higher catalytic efficiency? Use the equations we have learned to support your answer. c. Draw a graph of initial reaction rate versus substrate concentration for both substrates, A and B. Put both lines on the same graph and ensure that each curve has a shape that is consistent with the data presented in this question. Label both axes and label each curve as being either Substrate A or B.
An enzyme will attach itself to one or more molecules of the reactant in order to catalyze the reaction. They are the substrates for the enzyme. One substrate may be converted into a number of products during various reactions.
In some, two substrates combine to form a single, bigger molecule or to swap components. For the substrate, enzymes are extremely selective. As a result, they are ineffective for many types of reactions. Given that the geometry of the enzyme's binding site and the shape of the substrate are quite similar, the lock and key concept is predicated on this. .

Additionally, it is utilised to maintain a record of the job done so that any issues or problems can be immediately resolved. Additionally, notes concerning prospective issues, such as a worn component or a potential safety concern, may be included in the record. The log should typically be updated following each maintenance task to ensure that records are complete and correct. Maintaining maintenance records can help organisations save time and money while ensuring that equipment and facilities are in good functioning condition.
