Depth from defocus (DFD) based on optical methods is an effective method for depth reconstruction from 2D optical images. However, due to optical diffraction, optical path deviation occurs, which results in blurring imaging. Blurring, in turn, results in inaccurate depth reconstructions using DFD. In this paper, a nanoscale depth reconstruction method using defocus with optical diffraction is p...

Recently, the performance of several linear multiuser receivers including the matched filter receiver, the decorrelator receiver, and the MMSE receiver has been analyzed in CDMA systems with random sequences. Little work has been done for nonlinear decision feedback receiver. In this paper, we extend the results for linear multiuser receivers to an asynchronous CDMA system with an adaptive deci...

Purpose – This paper aims to develop path-planning techniques that support a general selective disassembly planner in a virtual reality environment. Design/methodology/approach – The paper presents an automatic selective disassembly planning and two path-planning techniques that support it. The first one is based on single translations, while the second is based on the generation of a random se...

Multiuser decision-feedback detectors (DFDs) for direct-sequence code-division multiple access, based on the minimum mean-squared error (MMSE) performance criterion, are described. Both successive and parallel feedback (interference cancellation) with hard decisions are considered. An iterative DFD is presented, which consists of cascaded DFDs, each performing successive cancellation. The two-s...

* Corresponding author: [email protected] Abstract The end-of-life (EOL) disassembly is an important process in the product retirement stage. In order to improve the ease of disassembly, it is essential to design a product which can be easily disassembled. In this paper, a novel concept of eco-architecture is introduced and a method for analyzing the eco-architecture of a product at the configura...

An important aspect of Design for the Life Cycle is assessing the disassemblability of products. A product designed for disassembly can be quickly and easily broken down so its components can be recycled or refurbished. The use of virtual prototyping is proposed to aid the assessment of product disassembly by enabling the designer to virtually disassemble the product. A virtual prototype is a m...

The current study was conducted to evaluate carcass characteristics, objectives and sensory meat qualities of Hanwoo longissimus muscle as affected by ultimate pH. Twenty-four steers and bulls (556±53 kg and 0.63±0.32 cm for live weight and backfat thickness, respectively) were used. As there was a linear relationship (r = 0.77) between lean meat color and ultimate pH, cattles were thus segrega...

Design for disassembly approaches are crucial supporting industrial circular economy transition. However, a significant limitation of current design methods is their inability to model the impacts product's end-of-life status on realized effort and subsequent effects implemented strategies. To address this gap, our work proposes novel approach termed Circular Disassembly corresponding model, ca...
