Which of the following is/are the advantages of using a control chart for inspection? (i) A control chart indicates whether the process is in control or out of control. (ii) A control chart determines process variability. (iii) A control chart ensures product quality. (iv) Scrap or percentage reduction can be reduced by taking the necessary actions in time against the warnings indicated by control charts. (v) Control charts build up the reputation of the organization through customer’s satisfaction. (vi) The control chart can detect the unusual variations taking place in a process.
Based on the given para, answer the following question. Sensitivity considerations often are important in the design of Control Systems. Because all physical elements have properties that change with environment and age, we cannot always consider the parameters of the Control System to be completely stationary over the entire operating life of the system. For instance, the winding resistance of an electric motor changes as the temperature of the motor rises during operation. Control systems with electric components may not operate normally when first turned on because of the still-changing system parameters during warmup. This phenomenon is sometimes called “morning sickness”. Most duplicating machines have a warmup period during which time operation is blocked out when first turn on. A good Control System should be: (a) Very sensitive to parameter variations (b) Insensitive to parameter variations (c) Insensitive to input commands (d) Sensitive to input commands Which of the above are correct?
Consider a control unit generating the control signals. These control signals are divided into five mutually exclusive groups as shown below: Groups  G1  G1  G1  G1  G1 Control  Signals   3  7  10  12  2 How many bits are saved using the Vertical Micro-programmed instead of Horizontal Micro-programmed control unit?
Examine the following statements about span of control and identify the ones which are true?
1. More task complexity requires narrower span of control.
2. Routine tasks can have greater span of control than exceptional tasks.
3. When tasks are dissimilar, then span of control can be larger.
4. Spans of control are generally narrower at the top and broader at the bottom of the hierarchy.
Consider the following statements regarding the cellular system/network: 1. Cellular systems use open-loop power control and closed-loop power control. 2. For FDMA system, the capacity of a cable is more as compared to the number of frequency channels allocated to it. 3. A cell has L potential subscribers and is able to handle N simultaneous users. If L > N, then the system is referred to a nonblocking. Which of the above statements are not correct?
HACCP is a preventive programme for hygienic control and food safety. Arrange the following steps of the HACCP system intheir correct sequence.
1. Identifying critical control points.
2. Monitoring each critical control point.
3. Developing criteria for control and prevention.
4. Identification and assessment of hazards.
5. Taking immediate corrective action.
Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems. What inference can be drawn from the above?
Given below are three quantities named A, B and C. Based on the given information, determine the relation among the three quantities.

Quantity A: What is the percentage increase in his donation in second year as compared to the first year? Quantity B: What is the percentage increase in his donation in third year as compared to the second year? Quantity C: What is the percentage increase in his donation in fourth year as compared to the third year?
