1.      18 Is it a requirement for the ARPA to provide warning on connected external equipment?

Yes

2.      Is it a requirement for an ARPA to be sea and ground stabilised?

Yes

3.      Comparing manual and automatic acquisition, which is most sensitive?

Manual acquisition

4.      What is the difference between a tracking gate and a tracking window?

It is the same thing

5.      What is the purpose of digitizing the radar echoes?

The ARPA tracking system only work with digital signals

6.      What is the purpose of the steady course filter?

Provide stabile target information

7.      Can a target reduction of speed activate the fast filter?

Yes

8.      Can a target course change deactivate the slow filter?

Yes

9.     

4.1 The stages of learning as Dienes
The learning process is a process based on abstraction, generalization and communication. This process of abstraction is to accurately analyze and Dienes identifies six different stages in it:
Stage 1: introduces the individual in the middle => Game Free
2nd stage: review, manipulate, get rules => Structured Games
3rd stage: becoming aware of the common structure to games made
4th stage: representation of the common structure graphically or schematically => Stage representative
5th stage study of the properties of abstract structure, which implies the need to invent a language => Stage symbolic
6th stage: Construction of axioms and theorems => formal Stage
Her pedagogical approach

36.      Does current and drift effect the True vector on a relative motion display?

Yes

2.      If you input gyro course to the ARPA, what can you expect?

Error in other ships calculated course

3.      Why is raster scan display “lock up” so dangerous?

The displayed information is no longer relevant

4.      What is dangerous with operating the ARPA in mixed mode over time?

Forgetting that this actually in mixed mode

5.      What can you expect from the ARPA target tracking system in auto acquisition mode?

Small and weak targets may not be acquired

6.      Doesthe line connecting the PAD or POS whit the target indicate target speed?

No

7.      What is the meaning of a flashing triangle, apex pointing down?

New target

1. Dynamic Analysis of Buildings per IS 1893:2016

Dynamic analysis considers the actual dynamic behavior of a building under earthquake ground motion, including its mass, stiffness, natural periods, and mode shapes.

• Methodology: It is primarily carried out by Modal Response Spectrum Analysis.
• Idealization: The building is idealized as a system with lumped masses at floor levels and structural elements represented by their appropriate stiffness.
• Eigenvalue Problem: Natural frequencies and mode shapes are determined by solving the structural system's eigenvalue problem.
• Modal Analysis: Each mode of vibration is analyzed separately using the design response spectrum specified in IS 1893:2016.
• Seismic Coefficient: The design horizontal seismic coefficient

5) The 3R concept in solid waste management stands for:

Ans: (a) Reduce, Reuse, Recycle.

6) Which of the following is a method of solid waste processing?

Ans: (d) All of the above.

7) The major product obtained from composting is:

Ans: (b) Compost/manure.

Ans: (b) Safe disposal of residual solid waste.

9) Incineration

1. Base Load and Peak Load Analysis

Base Load:

• Base load is the minimum continuous load demanded by consumers throughout the day.
• It remains almost constant for a large part of the 24-hour period.
• Base-load power plants operate continuously and supply the basic electricity demand.
• Thermal, nuclear, and large hydroelectric power plants are commonly used for base-load operation.
• Base-load plants generally have high efficiency and low operating costs but may have higher initial costs.

Peak Load:

• Peak load is the maximum electrical load occurring during certain periods of the day when electricity demand is high.
• It occurs mainly during morning and evening peak hours due to increased domestic and industrial consumption.
• Peak-load plants are designed to start

1. Injection Molding

Injection molding is a plastic-shaping process in which molten plastic is injected under high pressure into a mold cavity, where it cools and solidifies to take the shape of the mold.

Construction Components

• Hopper: Funnel-shaped container at the top of the barrel; feeds plastic pellets.
• Barrel: Thin-walled cylinder housing the screw; features multiple heating zones.
• Screw: Comprises three zones—feed, compression, and metering; moves axially.
• Non-return valve: Fitted at the top of the screw.
• Nozzle: Connects the barrel to the mold; controls the flow.
• Cylinder for screw ram: Pushes the screw forward during the injection stroke.
• Stationary platen: Fixed mold-half section.
• Movable platen: Moves forward and backward along the rods
