Krylov subspace recycling is a process for accelerating the convergence of sequences of linear systems. Based on this technique we have recently developed the recycling BiCG algorithm. We now generalize and extend this recycling theory to BiCGSTAB. Recycling BiCG focuses on efficiently solving sequences of dual linear systems, while the focus here is on efficiently solving sequences of single l...

Polyethylene terephthalate (PET) bottle recycling is a highly automated task; however, manual quality control required due to inefficiencies of the process. In this paper, we explore automation sub-task, namely visual detection, using convolutional neural network (CNN)-based methods and synthetic generation labelled training data. We propose pipeline tailored for transparent crushed PET detecti...

Due to the requirement of exploitation marine resources, execution specific underwater tasks by onboard manipulators has become one key research fields in domestic and all over world. Based on capture system designed for UUV recycling task, which consists an manipulator a mechanical device, this paper first constructs kinematics dynamics model through theoretical analysis such as mechanics theo...

Dual recycling is the combination of signal recycling and power recycling; both optical techniques improve the shot-noise-limited sensitivity of interferometric gravitational-wave detectors. In addition, signal recycling can reduce the loss of light power due to imperfect interference and allows, in principle, to beat the standard quantum limit. The interferometric gravitational-wave detector G...

The use of plastics for packaging has some advantages, since they are flexible and inexpensive. However, most single use, which, combined with low recycling or reuse ratios, contributes substantially to environmental pollution. This work is part a project studying the habits Portuguese citizens concerning plastic food focuses on aspects related sustainability. survey was carried out via an onli...

Waste electrical and electronic equipment (WEEE) has been one of the fastest growing waste streams worldwide. Effective and efficient management and treatment of WEEE has become a global problem. As one of the world's largest electronic products manufacturing and consumption countries, China plays a key role in the material life cycle of electrical and electronic equipment. Over the past 20 yea...

This fact sheet is part of a series highlighting different recyclable commodities. According to dictionary.com, a commodity is as “an article of trade or commerce; something of use, advantage, or value; any unprocessed or partially processed good.” When a product is recycled, original commodity material becomes new products. The recyclable commodity fact sheet series is designed to answer commo...
