Abstract The proper choice of strata boundaries is an important factor determining the efficiency estimator considered characteristics a population. In this article, Cum Rule (i=3,4) for obtaining approximately optimum has been applied, taking into account single-study variable along with two concomitant variables serving as basis stratification variables. relative proposed methods demonstrated...

This review presents a thorough survey of academic work on the chassis design by FEA and application of design of experiment method in it. It surveys most literature published in English language. The review aims to provide insight into the truck chassis design and act as a guide for researchers working on both FEA and DOE method for chassis design. The main objective of the design is to obtain...

The suppression of constant-input limit cycles when designing second-order-statespace digital filters is addressed in this paper. A set of three sections yet proposed in the literature is revisited, focusing on the specific block called type III structure. It is shown that there is an optimum version of that section, what is the main contribution of the paper. The noise performance of the optim...

2 Variables under study In our participation in this year’s track we studied three groups of variables and selected relationships between these variables. The three groups of variables focus on variables relating to the assessors themselves (section 2.1.1), the questions set (section 2.1.2) and the answers presented (section 2.1.3). In this section we discuss the variables we selected and how w...

An approach to compute optimum seismic design parameters is presented. It is based on the optimization of the expected present value of the total cost, which includes the initial cost of structures as well as the cost due to earthquakes. Different types of seismicity models are considered, including one for characteristic earthquakes. Uncertainties are included in some variables to observe the ...

High-pressure air enters the air-turbine of the dental handpiece and strikes the blades to drive the impeller. The air-turbine has impeller and the air tube is connected to the air-turbine housing. The flowfield of the air-turbine were investigated for the optimum air-turbine design using ANSYS CFX. The objective of the research was to find an optimum design variables for the air-turbine to inc...
