| 1 | 950℃时效条件下硼对S31254不锈钢析出相的影响显示文摘采用管式加热炉对S31254不锈钢在950℃下时效不同时间的第二相析出行为进行了研究,重点研究了硼的添加量对析出速度的影响规律。研究表明,在950℃保温约5 min后不添加硼的S31254不锈钢就可以看到明显的第二相析出;当添加0. 002%的硼后,第二相的析出时间延长到10 min,且时效时间在30 min后才会大量析出第二相;当继续添加硼到0. 004%后,第二相的时间析出延长到了30 min,且析出的第二相尺寸要小于不添加硼的试样。 | 白晋钢 崔一士 王剑 董楠 Qurashi Muhammad Saqlain 杨永超 韩培德 | 2019 | 金属热处理2019，44，9： | 4 |

| 3 | Effect of compression deformation on precipitation phase behavior of B-containing S31254 super austenitic stainless steel显示文摘Effects of compression deformation on the sigma-phase precipitation behavior of B-containing S31254 stainless steel after solution treatment were studied using the Gleeble compression test. The cold and hot processing characteristics of B-containing S31254 stainless steel were evaluated, and the results show that the speed of compression deformation increased the precipitation rate of the sigma phase, and the location of precipitation extended from the austenite grain boundary to the original hot rolling deformation area. During cold deformation at room temperature, the precipitation rate increased when the deformation reached at 40%. Deformation at 950℃ affected precipitation more obviously. At 1074 ℃, when the deformation reached 20%, the precipitated phases started increasing, and above this deformation range, precipitation began decreasing. Also, at 1074℃ the deformation accelerated the precipitation of sigma phase;but with deformation, there was a change in critical temperature for the sigma-phase excursion. The precipitation position of the sigma phase is strongly related to the area of the original hot rolling deformation. With an increase in the deformation amount, precipitates in this region appeared as coarse-grained, skeletal, and network-like features. | Jin-gang Bai Yi-shi Cui Jian Wang Nan Dong Muhammad Saqlain Qurashi Hai-rui Wei Yong-chao Yang Pei-de Han | 2019 | Journal of Iron and Steel Research(International)2019，26，7： | 1 |
| 4 | Single-atom catalysts for electrochemical N_(2)reduction to NH_(3)显示文摘The increasing demand for clean energy and growing concerns regarding environmental sustainability have led to greater attention devoted toward the production of clean fuels via green chemistry.In this respect,ammonia is a green alternative to fossil fuels and can serve as a clean energy source.There is now great interest in realizing the electrochemical reduction in atmospheric nitrogen(N_(2))for cheap,environmentally friendly and reliable ammonia(NH_(3))production worldwide.However,the robustness of the triple bond in N2 and the low efficiency of candidate catalysts limit the utility of this conversion.Single atom catalysts have been found to be more effective than nanoparticles due to their unique properties,and thus have been studied extensively for the nitrogen reduction reaction.In this review,we have covered the recent advances in design and synthesis of noble metal and non-noble metal single atom catalysts for the electrochemical reduction in nitrogen during the years 2018-2022.The catalyst efficiencies,with reference to coordination preferences and theoretical studies have been discussed.Moreover,we also provide insights into the current challenges and some considerations for further future studies. | Muhammad Saqlain lqbal Zhi-Bo Yao Yu-Kun Ruan Ramsha Iftikhar Lei-Duan Hao Alex WRobertson Syed Muhammad Imran Zhen-Yu Sun | 2023 | Rare Metals2023，42，4： | 1 |
| 5 | Human Behavior Classification Using Geometrical Features of Skeleton and Support Vector Machines显示文摘Classification of human actions under video surveillance is gaining a lot of attention from computer vision researchers.In this paper,we have presented methodology to recognize human behavior in thin crowd which may be very helpful in surveillance.Research have mostly focused the problem of human detection in thin crowd,overall behavior of the crowd and actions of individuals in video sequences.Vision based Human behavior modeling is a complex task as it involves human detection,tracking,classifying normal and abnormal behavior.The proposed methodology takes input video and applies Gaussian based segmentation technique followed by post processing through presenting hole filling algorithm i.e.,fill hole inside objects algorithm.Human detection is performed by presenting human detection algorithm and then geometrical features from human skeleton are extracted using feature extraction algorithm.The classification task is achieved using binary and multi class support vector machines.The proposed technique is validated through accuracy,precision,recall and F-measure metrics. | Syed Muhammad Saqlain Shah Tahir Afzal Malik Robina khatoon SyedSaqlain Hassan Faiz Ali Shah | 2019 | Computers, Materials & Continua2019，，8： | 1 |
| 6 | Multi-valued interval neutrosophic linguistic soft set theory and its application in knowledge management显示文摘This study proposed the concepts of a multi-valued interval neutrosophic linguistic soft set(MVINLSS)by integrating the concepts of multi-valued interval neutrosophic soft set and linguistic set.MVINLSS is presented as it can deal with ambiguous and uncertain information in decision making which is characterised by linguistic membership.This proposed set amalgamates quantitative assessment with the qualitative assessment which can solve complex problems with ambiguity,uncertainty,and inconsistency.It can be an effective tool to describe the real decision-makers’opinions and reflect their hesitancy.Then,the authors propose the basic operational rules of MVINLSS.Moreover,they define a multi-valued interval neutrosophic linguistic soft weighted arithmetic averaging operator.This work proposed a multi-criteria decision-making(MCDM)method which considers different priority levels of criteria and the criteria values take the form of multi-valued interval neutrosophic linguistic soft numbers.Finally,the proposed MCDM method is applied to the knowledge management case,considering 11 criteria. | Nor Liyana Amalini Mohd Kamal Lazim Abdullah Ilyani Abdullah Muhammad Saqlain | 2020 | CAAI Transactions on Intelligence Technology2020，5，3： | 0 |
| 7 | Context Based Adoption of Ranking and Indexing Measures for Cricket Team Ranks显示文摘There is an international cricket governing body that ranks the expertise of all the cricket playing nations,known as the International Cricket Council(ICC).The ranking system followed by the ICC relies on the winnings and defeats of the teams.The model used by the ICC to implement rankings is deficient in certain key respects.It ignores key factors like winning margin and strength of the opposition.Various measures of the ranking concept are presented in this research.The proposed methods adopt the concepts of h-Index and PageRank for presenting more comprehensive ranking metrics.The proposed approaches not only rank the teams on their losing/winning stats but also take into consideration the margin of winning and the quality of the opposition.Three cricket team ranking techniques are presented i.e.,(1)Cricket Team-Index(ct-index),(2)Cricket Team Rank(CTR)and(3)Weighted Cricket Team Rank(WCTR).The proposed metrics are validated through the collection of cricket dataset,extracted from Cricinfo,having instances for all the three formats of the game i.e.,T20 International(T20i),One Day International(ODI)and Test matches.The comparative analysis between the proposed and existing techniques,for all the three formats,is presented as well. | Raja Sher Afgun Usmani Syed Muhammad Saqlain Shah Muhammad Sher Ramzan Abdullah Saad A.L-Malaise AL-Ghamdi Anwar Ghani Imran Khan Farrukh Saleem | 2020 | Computers, Materials & Continua2020，，11： | 0 |
| 8 | 基于团簇式的GH2132高温合金成分协同变化关系显示文摘GH2132(A286)是析出强化型铁基高温合金,其含有多种合金化元素,为避免不合适的成分选择导致的综合性能失配,通过重点分析东北特钢提供的产品成分,解析国标成分区间的合理性,本文提出了一个更加合适的新成分标准形式。为此,引入“团簇加连接原子”结构模型,该模型将合金成分的结构载体表述为[中心-第一近邻](连接原子)的团簇成分式形式。首先将合金化元素分为基体Fe、稳定奥氏体的(Ni,Mn)、稳定铁素体的(Cr,Mo,V,Si,Ti,Al)、以及不进入团簇式的(C,P,S,B)。通过分析国标规定的成分区间和实际合金成分,指出合金的实际成分区间远小于国标范围,并由16原子的成分式限定:Fe_((8.5~9.0)±0.25)(Ni,Mn)_(4±0.25)(Cr,Mo,V,Si,Ti,Al)_(3~3.5)。进而揭示了同类元素内部的质量百分比协同变化关系,即24.6≤Ni+Mn≤28.0和17.4≤Cr+0.6Mo+V+1.7Si+1.1Ti+1.8Al≤20.4。由此更合理地限定Mn、Si元素成分区间,并对东北特钢的合金成分提供了改进建议。 | 李陌 李言成 王清 董闯 QURASHI Muhammad Saqlain 赵亚军 张爽 李瑛 王连超 万鹏 | 2022 | 材料科学与工艺2022，30，6： | 0 |
| 9 | Improvement in Sensing Accuracy of an OFDM-Based W-Band System显示文摘Orthogonal frequency division multiplexing (OFDM) waveform is promising to converge communications and sensing functionalities for future wireless applications. This paper presents a novel method to improve the OFDM-based sensing accuracy by estimating the delay/Doppler leakages in the channel matrix, which is constructed by the received and the transmitted OFDM symbols. Both simulation and proof-of-concept experiment validate the proposed method for sensing improvement.The experiment uses a heterodyne W-band system at 97 GHz to transmit and receive an OFDM waveform of bandwidth 3.9 GHz.We achieve an improvement in sensing accuracy by an order of magnitude which is significant for OFDM-based converged systems. | Nazar Muhammad Idrees Zijie Lu Mu hammad Saqlain Hongqi Zhang Shiwei Wang Lu Zhang Xianbin Yu | 2022 | Journal of Communications and Information Networks2022，7，1： | 0 |
