Often, the best control system is the simplest. When the system you’re trying to control is highly nonlinear, this can lead to very complex controllers. This video continues our discussion on control systems in practice by talking about a simple form of nonlinear control: gain scheduling. ...
What is an Actuarial Gain Or Loss? Actuarial gain or loss refers to an increase or a decrease in the projections used to value a corporation’s defined benefit pension plan obligations. The actuarial assumptions of a pension plan are directly affected by the discount rate used to calculate the...
Capital gain is the increase in the value of anycapital asset(investment or real estate) that gives it a higher worth than the purchase price. The gain is not realized until the asset is sold. A capital gain may be short-term (one year or less) or long-term (more than one year) an...
Every screen material on the market has a so-called gain factor. This is perhaps the most important specification for any screen. Some screens are "low gain" and some are "high gain." Most white home theater screens are low gain, and carry ratings in the range of 1.0 to 1.3 gain. Som...
If we introduce another feedback loop through a negative feedback gain of F, as shown in Figure 1.2.2, theinput-output relationof the overall system is 如果我们通过F的负反馈增益引入另一个反馈回路,如图1.2.2所示,整个系统的输入-输出关系为 ...
problem-solution fitis at the heart of this process. You'll know you've achieved problem-solution fit when customers tell you unequivocally that they care about the job your product can do for them, and that it would either alleviate a major pain point or create a significant gain for ...
LQR is a type of optimal control based on state-space representation. In this video, we introduce this topic at a very high level so that you walk away with an understanding of the control problem and can build on this understanding when you are studying the math behind it. This video wi...
FP&A is a corporate finance function responsible for analyzing financial data to help plan effective business strategies and optimize business decisions.
Is More Antenna Gain Better? The Logarithmic dB Scale Antenna engineers use a logarithmic scale to express this apparent 2x (times two) mirror power doubling as “+3 dBi”. It still means “doubling”. Here are some other examples of ratios or multipliers on the engineering dBi gain log sca...
Observability is the ability to understand the internal state or condition of a complex system based solely on knowledge of its external outputs, specifically its telemetry. Observability plays a crucial role in maintaining the availability, performance and security of modern software systems andcloud co...
