The properties of a variety of mouth protectors and sheet materials used to fabricate custom mouth protectors were determined in order to recommend limits for a specification. Hardness, water sorption, water solubility, impact absorption, and tear strength were measured, and limits for these properties were suggested.

Hematopoietic stem cells (HSCs) are the therapeutic component of bone marrow transplants, but finding immune-compatible donors limits treatment availability and efficacy. Recapitulation of endogenous specification during development is a promising approach to directing HSC specification in vitro, but current protocols are not capable of generating authentic HSCs with high efficiency. Across phy...

The target costing technique, mathematically discussed by Sauers, only uses the p C index along with Taguchi loss function and X -R control charts to setup goal control limits. The new specification limits derived from Taguchi loss function is linked through the p C value to X -R control charts to obtain goal control limits. In this study, the target costing technique is exploited by further co...

  Background and Objective: Improved and modified automation will require the development of smart process control systems that provide on-line decisions to release patients’ test results based on high analytical quality assurance formula. Materials and Methods: We collected patients’ test results from 10840 healthy subjects based on 1.96z as truncation limit for 29 common haematochemical ana...

An essentially complete formal specification of safety requirements for railway interlockings has been developed. The work is part of as project with the Swedish National Rail Administration investigating the feasibility of using formal methods for the analysis of interlockings in a production setting. An overview of the specification is given and two ongoing case studies on verifying interlock...

In the area of software engineering there have been very few efforts to automate the translation from specifications written in natural language to the formal specification languages. Writing of the specifications in natural language is always depending on context and it is commonly vagueness; this represents the major reasons of the challenge. This paper discusses the design of a tool for tran...

This paper develops an approach to minimize the number of process tooling adjustments and deliver an acceptable fraction of non-conforming products based on given product quality specification limits in assembly processes. A linear model is developed to describe the relationships between product quality and process tooling locating positions. Based on the model, the process mean shifts of tooli...

Fuzzy process capability indices are used to determine whether a production process is capable of producing items within specification tolerance, where instead of precise quality we have two membership functions for specification limits. In practice these indices are estimated using sample data and it is of interest to obtain confidence limits for fuzzy capability index given a sample estimate....
