# Accelerated failure time model

In the statistical area of survival analysis, an accelerated failure time model (AFT model) is a parametric model that provides an alternative to the commonly used proportional hazards models. Whereas a proportional hazards model assumes that the effect of a covariate is to multiply the hazard by some constant, an AFT model assumes that the effect of a covariate is to accelerate or decelerate the life course of a disease by some constant. This is especially appealing in a technical context where the 'disease' is a result of some mechanical process with a known sequence of intermediary stages. (Wikipedia).

Why Time Delay Matters | Control Systems in Practice

Time delays are inherent to dynamic systems. If you’re building a controller for a dynamic system, it’s going to have to account for delay in some way. Time-Delay Systems: Analysis and Design with MATLAB and Simulink: http://bit.ly/2C354yp Time delays exist in two varieties: signal dist

Time Domain Analysis: Performance Metrics for a First Order System

In this video we introduce the concept of time domain analysis for dynamic systems. We examine a first order dynamic system and derive how various performance metrics (such as steady state error, settling time, and rise time) are related to the parameters of the system. Topics and time s
