Determining the Sample size for Estimation of the CCC-R Control Chart Parameters Based on Estimation Costs
In today's highly competitive industrial environment due to fast technology development, quality practitioners will to detect out-of-control situations and take actions whenever is necessary as soon as possible. Accordingly, new statistical procedures have been enhanced incessantly both to handle high yield processes along with looking for methods of minimizing all quality cost. CCC-r chart, th...
متن کاملSoftware Migration Project Cost Estimation using COCOMO II and Enterprise Architecture Modeling
Large amounts of software are running on what is considered to be legacy platforms. These systems are often business critical and cannot be phased out without a proper replacement. Migration of these legacy applications can be troublesome due to poor documentation and a changing workforce. Estimating the cost of such projects is nontrivial. Expert estimation is the most common method, but the m...
متن کاملDesign, Modeling, and Construction of a New Tactile Sensor for Measuring Contact-Force
This paper presents the design, modeling, and testing of a flexible tactile sensor and its applications. This sensor is made of polymer materials and can detect the 2D surface texture image and contact-force estimation. The sensing mechanism is based on the novel contact deflection effect of a membrane. We measure the deflection of the membrane with measuring the strain in the membrane with emb...
متن کاملDesign and Modeling of a New Type of Tactile Sensor Based on the Deformation of an Elastic Membrane
This paper presents the design and modeling of a flexible tactile sensor, capable of detecting the 2D surface texture image, contact-force estimation and stiffness of the sensed object. The sensor is made of polymer materials. It consists of a cylindrical chamber for pneumatic actuation and a membrane with a mesa structure. The inner radius of the cylindrical chamber is 2cm and its outer radius...
متن کاملSample size determination for logistic regression
The problem of sample size estimation is important in medical applications, especially in cases of expensive measurements of immune biomarkers. This paper describes the problem of logistic regression analysis with the sample size determination algorithms, namely the methods of univariate statistics, logistics regression, cross-validation and Bayesian inference. The authors, treating the regr...
