How do you find the minimum variance of an unbiased estimator? Method 1: If we can find a function of S = S(Y ), say U(S) such that E[U(S)] = g(ϑ) then U(S) is a unique MVUE of g(ϑ). Method 2: If we can find any unbiased estimator T = T(Y ) of g(ϑ), then […]
What is a flight envelope in aviation?
What is a flight envelope in aviation? In aerodynamics, the flight envelope, service envelope, or performance envelope of an aircraft refers to the capabilities of a design in terms of airspeed and load factor or altitude. The term is somewhat loosely applied, and can also refer to other measurements such as manoeuvrability. What can be […]

What are the types of dynamometer?
What are the types of dynamometer? There are two main types of dynamometers, which are both used frequently in the auto industry and in industrial and manufacturing processes. These are chassis dynamometers and engine dynamometers. Chassis dynos measure automobile wheel rotation with computer software in order to determine engine or motor torque. What are the […]
What is electrical output?
What is electrical output? Electrical Output means the total quantity of all actual net electricity generated by the System (measured in kilowatt-hours (kWh)) and delivered to the Grid, in any given period of time. Which is an example of an output device? An output device is any piece of computer hardware equipment which converts information […]
How is tower crane lift capacity calculated?
How is tower crane lift capacity calculated? The base formula for the Crane Capacity Index is: * For each main boom length at each radius the “Lifting height*Capacity” is calculated. At one radius the value of “Lifting height*Capacity” varies with different main boom lengths. At each radius the maximum value of “Lifting height*Capacity” is chosen. […]
How is iron turned into steel?
How is iron turned into steel? To make steel, Iron ore and other iron bearing materials, coke, and limestone are charged into the blast furnace from the top and work their way down, becoming hotter as they sink in the body of the furnace. At the bottom of the furnace, temperatures rise to well over […]
What are the phases of pharmacodynamics?
What are the phases of pharmacodynamics? Drug action usually occurs in three phases: Pharmaceutical phase. Pharmacokinetic phase. Pharmacodynamic phase. What is the Pharmaceutic phase? The pharmaceutic phase (dissolution) is the first phase of drug action. In the gastrointestinal (GI) tract, drugs need to be in solution so they can be absorbed. A drug in solid […]
In what forms can energy cross the boundaries of a closed system?
In what forms can energy cross the boundaries of a closed system? The first law of thermodynamics is an expression of the conservation of energy principle. Energy can cross the boundaries of a closed system in the form of heat or work. Energy transfer across a system boundary due solely to the temperature difference between […]
In what order will TCP generally send all segments?
In what order will TCP generally send all segments? Once the connection is established between the applications, It can send data to each other. Question 11: In what order will the Transmission Control Protocol (TCP) generally send all segments? All segments in TCP are sent through sequential order. In what order will the Transmission Control […]
