Synergic Effect of Reworking for Imperfect Quality Items with the Integration of Multi-Period Delay-in-Payment Article

Waqas Ahmed, Muhammad Moazzam, Biswajit Sarkar, Saif Ur Rehman

Engineering 2021, Volume 7, Issue 2,   Pages 260-271 doi: 10.1016/j.eng.2020.07.022

Abstract: On occasion, the expected lot may include a fraction of defective items.These imperfect items still have worth and can be sold to customers after repair.It is cost-effective and sustainable to rework such items in nearby repair workshops rather than returnThe reworked items can be returned from the workshop to the buyer when shortages are equal to the quantityof imperfect items.

Adaptive robust beamformer formulti-pair two-way relay networks with imperfect channel state information

Jin WANG,Feng SHU,Ri-qing CHEN,Yu-di CUI,Yu CHEN,Jun LI

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 3,   Pages 265-280 doi: 10.1631/FITEE.1500134

Abstract: In wideband multi-pair two-way relay networks, the performance of beamforming at a relay station (RS) is intimately related to the accuracy of the channel state information (CSI) available. The accuracy of CSI is determined by Doppler spread, delay between beamforming and channel estimation, and density of pilot symbols, including transmit power of pilot symbols. The coefficient of the Gaussian-Markov CSI error model is modeled as a function of CSI delay, Doppler spread, and signal-to-noise ratio, and can be estimated in real time. In accordance with the real-time estimated coefficients of the error model, an adaptive robust maximum signal-to-interferenceand- noise ratio (Max-SINR) plus maximum signal-to-leakage-and-noise ratio (Max-SLNR) beamformer at an RS is proposed to track the variation of the CSI error. From simulation results and analysis, it is shown that: compared to existing non-adaptive beamformers, the proposed adaptive beamformer is more robust and performs much better in the sense of bit error rate (BER); with increase in the density of transmit pilot symbols, its BER and sum-rate performances tend to those of the beamformer of Max-SINR plus Max-SLNR with ideal CSI.

CO2 capture using membrane contactors: a systematic literature review

Sanaa Hafeez, Tayeba Safdar, Elena Pallari, George Manos, Elsa Aristodemou, Zhien Zhang, S. M. Al-Salem, Achilleas Constantinou

Frontiers of Chemical Science and Engineering 2021, Volume 15, Issue 4,   Pages 720-754 doi: 10.1007/s11705-020-1992-z

Abstract: With fossil fuel being the major source of energy, CO emission levels need to be reduced to a minimal amount namely from anthropogenic sources. Energy consumption is expected to rise by 48% in the next 30 years, and global warming is becoming an alarming issue which needs to be addressed on a thorough technical basis. Nonetheless, exploring CO capture using membrane contactor technology has shown great potential to be applied and utilised by industry to deal with post- and pre-combustion of CO . A systematic review of the literature has been conducted to analyse and assess CO removal using membrane contactors for capturing techniques in industrial processes. The review began with a total of 2650 papers, which were obtained from three major databases, and then were excluded down to a final number of 525 papers following a defined set of criteria. The results showed that the use of hollow fibre membranes have demonstrated popularity, as well as the use of amine solvents for CO removal. This current systematic review in CO removal and capture is an important milestone in the synthesis of up to date research with the potential to serve as a benchmark databank for further research in similar areas of work. This study provides the first systematic enquiry in the evidence to research further sustainable methods to capture and separate CO .

Finding misplaced items using amobile robot in a smart home environment Research Articles

Qi WANG, Zhen FAN, Wei-hua SHENG, Sen-lin ZHANG, Mei-qin LIU

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 8,   Pages 1036-1048 doi: 10.1631/FITEE.1800275

Abstract: Smart homes can provide complementary information to assist home service robots. We present a robotic misplaced item finding (MIF) system, which uses human historical trajectory data obtained in a smart home environment. First, a multi-sensor fusion method is developed to localize and track a resident. Second, a path-planning method is developed to generate the robot movement plan, which considers the knowledge of the human historical trajectory. Third, a real-time object detector based on a convolutional neural network is applied to detect the misplaced item. We present MIF experiments in a smart home testbed and the experimental results verify the accuracy and efficiency of our solution.
