Methods of designing equipment to improve quality have been developed by Taguchi. A key feature of these methods is the development of loss function, which quantifies the financial cost (loss) resulting from deviations from target dimensions. Total knee arthroplasties can fail due to prosthetic component malalignment. A Taguchi loss function for varus/valgus alignment of the prosthesis and revi...

this paper presents a new approach which is based on quality control in order to optimize supplier selection. using inspections, removing the defected materials and considering penalties for low quality materials are the main factors which we have considered in modeling. in this model costs are divided to three parts: 1- costs of purchasing 2- costs of inspection policy 3- costs of quality and ...

Abstract Hayabusa2 returned surface samples from the C-type near-Earth asteroid (162173) Ryugu to Woomera, South Australia, in December 2020. The are expected contain not only volatile components reflecting its primitive nature, but also solar wind due exposure space. Such volatiles may partly be released inside sealed sample container enclosing particle destruction or heating a contingency cas...

We propose a method to synthetically create or restore typical color filter array (CFA) pattern in digital images. This can be useful, inter alia, to conceal traces of manipulation from forensic techniques that analyze the CFA structure of images. For continuous signals, our solution maintains optimal image quality, using a quadratic cost function; and it can be computed efficiently. Our genera...

Automatic lighting design aims to provide users with semi-automated approaches, and easy-to-use tools, to configure lighting for 3D scenes. We present LIGHTOPEX the first fully automatic example-based local illumination lighting design system. Utilizing a wavelet-based lighting design framework, by which image quality is modeled using a cognitively inspired objective function, this approach to ...

The Airspace Flow Program (AFP) ground delays flights in order to control their flow through capacity constrained airspace regions. It has been successful in controlling traffic with reasonable delays, but the procedures must be improved upon to handle future projected demands. This paper explores a future AFP where centrally-managed rerouting and user input are incorporated into the initial re...

Segmentation using boundary finding is enhanced both by considering the boundary as a whole and by using model-based global shape information. Previous boundary finding methods have either not used global shape or have designed individual shape models specific to particular shapes. We apply flexible constraints, in the form of a probabilistic deformable model, to the problem of segmenting natur...

Next generation wireless communications are expected to rely on integrated networks consisting of multiple wireless technologies. Heterogeneous networks based on Wireless Local Area Networks (WLANs) and Wireless Wide Area Networks (WWANs) can combine their respective advantages on coverage and data rates, offering a high Quality of Service (QoS) to mobile users. In such environment, multi-inter...

This paper derives the optimal production-shipment policy for a vendor-buyer integrated system with imperfect quality and an amending product delivery plan using an algebraic method. It is assumed that the system may randomly produce certain portion of nonconforming products during each production run. Quality assurance in terms of inspection and rework has been given effect to the defective it...

In this paper we propose a pricing-enabled QoS for the hybrid UMTS/WLAN network. The proposed methodology is an integration of usage-based, non usage-based, static, and dynamic pricing schemes and DiffServ (Differentiated Services). We propose the utility function and cost function for our needs, and the pricing mechanism is based on differentiated service classes. By the affection of price, a ...
