    A New Approach in Capability Analysis of Processes Monitored by a Simple Linear Regression Profile

    , Article Quality and Reliability Engineering International ; Volume 32, Issue 1 , 2016 , Pages 209-221 ; 07488017 (ISSN) Karimi Ghartemani, M ; Noorossana, R ; Akhavan Niaki, S. T ; Sharif University of Technology

    Abstract
    In some quality control applications, quality of a product or a process can be characterized by a profile defined as a functional relationship between a response variable and one or more explanatory variables. Many researchers have contributed to the development of linear and nonlinear profiles to monitor a process or product. However, less work has been devoted to the development of process capability indices in profile monitoring to evaluate process performance with respect to specification limits. This paper presents a process capability analysis when the quality characteristic of interest is represented by a linear profile. Simulation analyses along with a real case study in leather... 

    Monitoring multivariate profiles in multistage processes

    , Article Communications in Statistics: Simulation and Computation ; Volume 50, Issue 11 , 2021 , Pages 3436-3464 ; 03610918 (ISSN) Bahrami, H ; Akhavan Niaki, T ; Khedmati, M ; Sharif University of Technology

    Abstract
    In some quality control applications, processes consist of multiple components, stations or stages to finish the final products or the services. Some quality characteristics in each stage of these processes (called multistage processes) can be represented by a relationship between a response and one or more explanatory variables which is named as profile. In this paper, a general model is proposed for monitoring multivariate profiles in multistage processes. To this aim, the multivariate form of the U transformation approach is first used to remove the effect of the cascade property between the stages. Then, three control schemes are employed to monitor the parameters of multivariate simple... 

    Two studies of framework-usage templates extracted from dynamic traces

    Abstract
    Object-oriented frameworks are widely used to develop new applications. They provide reusable concepts that are instantiated in application code through potentially complex implementation steps such as subclassing, implementing interfaces, and calling framework operations. Unfortunately, many modern frameworks are difficult to use because of their large and complex APIs and frequently incomplete user documentation. To cope with these problems, developers often use existing framework applications as a guide. However, locating concept implementations in those sample applications is typically challenging due to code tangling and scattering. To address this challenge, we introduce the notion of...
