综述 Review

A review of drag reduction by additives in curved pipes for single‐phase liquid and two‐phase flows


Paul O. Ayegba, Lawrence C. Edomwonyi‐Out, Nurudeen Yusuf, Abdulkareem Abubakar

A review of investigations on the effect of drag‐reducing agents in flows around curved pipes and bends is presented. Drag reduction in curved pipe flows are generally lower than in straight pipes and the mechanism is still not generally accepted. This review is a launch pad for future research as it highlighted some research gaps with appropriate recommendations.

1. Inverse functions for Monte Carlo simulations with applications to hitting time distributions


Avishai Ben‐David, Raghu Raghavan

We explore a well‐known probability (the F‐ratio distribution) as an alternative to generating look‐up tables and interpolations to obtain the required random time samples for hitting time distributions. Other Monte Carlo simulations in a number of fields of application may benefit from our method.



2. Stability of plasma‐enhanced atomic layer deposited barrier films in biological solutions


Ankit K. Singh, Katarina Adstedt, Tianxin Miao, Julie Champion, Preet M. Singh, Samuel Graham

Atomic layer deposited metal oxides are tested for their cytocompatibility and stability in different biological solutions. The viability of ALD films in biological solutions and their enhanced corrosion resistances opens up the possibility for a new class of materials that can be used for the protection of bioimplants and wearable devices.



3. Fresh insights into detonation nanodiamond aggregation: An X‐ray photoelectron spectroscopy, thermogravimetric analysis, and nuclear magnetic resonance study


Khabiboulakh Katsiev Vera Solovyeva Remi Mahfouz Edy Abou‐Hamad Wei Peng Hicham Idriss Ahmad R. Kirmani

The mechanism behind aggregation in detonation nanodiamonds is outlined. Surface oxygen functionalities, identified as C-O-C species, cross‐link the primary particles (ca. 4‐5 nm) forming large polydisperse aggregates. A facile acid hydrolysis is proposed for de‐aggregating the diamonds in high yields.

概述了爆轰纳米金刚石中聚集的机理。初级颗粒(约4-5纳米)通过表面的含氧官能团(确定为C -O-C物种)交联,形成较大的多分散的聚集体。此外,提出了一种简便的酸水解方法,以使金刚石高产率地解聚。


4. Predicting the actual location of faults in underground optical networks using linear regression


Owusu Nyarko‐Boateng, Adebayo Felix Adekoya, Benjamin Asubam Weyori

This research presents a machine learning (ML) approach to predict the actual location of a fiber cable fault in an underground optical transmission link. Linear regression in the python sci‐kit learn library was used to predict the actual location of a fault in an underground optical network. The MSE and MAE evaluation matrix used provided good accuracy results of 0.061291 and 0.080143, respectively.

本研究提出了一种机器学习方法来预测地下光传输链路中光缆故障的实际位置。采用python sci-kit learn库中的线性回归来预测地下光网中故障的实际位置。所用的MSE和MAE评价矩阵分别提供了0.061291和0.080143的良好准确度结果。


5. Design of home load management system for load rationing in Pakistan


Muhammad Bilal Butt, Saad Dilshad, Naeem Abas, Shoaib Rauf, Muhammad Shoaib Saleem

We report the design and implementation of a load rationing system that allows for load shedding management. The simulation analysis of a single‐family house is performed for automatic load reduction during peak hours in Proteus software. A hardware prototype is designed and applied so as to validate the proposed control system. The results show that the proposed scheme allows for an efficient peak shaving during peak hours.



6. Hot‐cracking susceptibility of fully austenitic stainless steel using pulsed‐current gas tungsten arc‐welding process


Mohamed Abu‐Aesh, Mohamed Taha, Ahmed Salem El‐Sabbagh, Lutz Dorn

In the present study, the effects of pulse frequency, time ratio, and pulse current on the cracking susceptibility of austenitic stainless steel thin sheets are investigated. A fan‐shaped cracking test specimen is adopted, and suitable final dimensions are obtained by conducting some preliminary experiments. The results are found to be significantly improved when compared with those of the continuous‐current process, indicating that the pulsed‐current gas tungsten arc‐welding process (PCGTAW) has an effective role in reducing the hot‐cracking susceptibility.



7. Using temporal convolution network for remaining useful lifetime prediction


Jungan Chen, Danjiang Chen, Gaoping Liu

Because of the inherently long‐term degradation process, it is necessary to learn temporal features from long history sequence data for remaining useful lifetime estimation. A temporal convolution network combining causal filters with dilated convolutions is hence used to expand the receptive field length of the network to improve prediction performance.



8. Cross‐domain bearing fault diagnosis with refined composite multiscale fuzzy entropy and the self organizing fuzzy classifier


Esther W. Gituku, James K. Kimotho, Jackson G. Njiri

The use of refined composite multiscale fuzzy entropy (RCMFE) for cross‐domain diagnosis of bearings is here introduced and verified with two publicly available datasets. Compared to related works, the proposed approach does not require deep learning for feature extraction nor any domain adaptation technique as the RCMFE feature is robust against changing operating conditions. Furthermore, the method does not need target domain data during training.
