Theory on the Design of Experiments

چکیده
An experiment is a structured model to measure the validity of a hypothesis. There is extensive literature on how to design an experiment, derived by taking a already run experiment as a starting point, and determining what could be done better to get results that are more conclusive. As a result, the concept of an experiment has been treated informally, but if we seek to design an experiment, we need a formal basis. This paper formalizes the concept of an experiment, and what it means to test a hypothesis. It defines what an experiment is, what a hypothesis is, it defines the concept of construct validity, which is similar to identification or internal validity, and establishes basic experimental design features necessary to get conclusive results. Future work on this paper will consider the case where not everything is controllable, and we have to test things indirectly. JEL Classification: C90, D78, D82

An Investigation into the Deep Drawing of Fiber-Metal Laminates based on Glass Fiber Reinforced Polypropylene
Abstract Fiber-metal laminates (FMLs) are new type of composite materials which could improve defects of traditional composites in ductility, formability, impact and damage tolerance. Drawing behavior of a thermoplastic based FML was investigated consisting of glass-fiber reinforced polypropylene composite laminate and aluminum AA1200-O as the core and skin layers, respectively. The effects o...
متن کاملProposing a Discharge Coefficient Equation for Triangular Labyrinth Spillways Based on Laboratory Studies
Labyrinth spillways are considered as suitable and economic structures because, firstly, their discharge flow rate, under low hydraulic heads, is high, and secondly, they occupy less space. The flow over these spillways is three-dimensional and is influenced by several parameters. This study endeavors to offer a new equation for the calculation of the discharge flow of triangular labyrinth spil...
متن کاملRobust Controller Design Based-on Aerodynamic Load Simulator Identification Driven by PMSM for Hardware-in-the-Loop Simulations
Aerodynamic load simulators generate the required time varying load to test the actuator’s performance in the laboratory. Electric Load Simulator (ELS) as one of variety of the dynamic load simulators should follows the rotation of the Under Test Actuator (UTA) and applies the desired torque to UTA’s rotor at the same time. In such a situation, a very large torque is imposed to the ELS from the...
