Authors: Jin Hailan , Chen Honglei , Qian Xueren , Jin Wanqi , Du Xinyue , Jin Can , Li Haojun , Li Hao , Zhu Yumo , Chao Junhyung
Published: November 2022

In this study, calcium carbonate, sepiolite, and commonly used diatomite (DE) carriers were mixed to prepare calcium carbonate or sepiolite mixed DE/nano-titanium dioxide (TiO2). The analyses of X-ray diffraction and scanning electron microscope confirmed that the particle size of nano-TiO2 was about 20–24 nm in DE/nano-TiO2, and the particles were relatively uniform. When (calcium carbonate and sepiolite + DE)/nano-TiO2 was used, the Ti content in the composite remained unchanged, while the particle size of nano-TiO2 increased to a certain extent. Among them, the use of (calcium carbonate + DE)/nano-TiO2 increased the Ti content in the composite material significantly. Therefore, the findings demonstrated the feasibility of nano-TiO2 supported by the mixed carrier.
Fischer–Tropsch Reactions and Product Distribution Suits for Downstream
Authors: Ma Wenping , Shafer Wilson D. , Martinelli Michela
Published: November 2022

Generic models for the mean carbon number n̄, H/C ratio β and chain growth probability α, as a function of C5+ selectivity for Fischer–Tropsch reactions, have been developed based on gas analysis data and product mass. These models allow predicting the parameters when detailed compositions of oil and wax are unavailable. Meanwhile, the distribution of individual 2–5 methyl paraffins of iron and cobalt catalysts containing K, Zr and Pt promoters or poisoned by COS and HBr were studied. The chain-length-dependent formation of methyl paraffins was demonstrated on both iron and cobalt catalysts. The fraction of the methyl paraffins produced on an active iron catalyst (15–22%) was 5–7 times higher than that of a cobalt catalyst (1–3%). Ethylidene (CH2CH–M) was proposed as one possible iso-chain growth monomer, based on the higher fraction of 3-methyl product. The effects of the promoters and the poisons on the formation of iso-paraffins and 1-olefin were complicated. K (Fe), Zr and S (Co) improved the formation of 1-olefins and suppressed the formation of iso-paraffins, partly due to the electronic effect (back-donation) of the promoters. Pt inhibited the formation of both 1-olefins and iso-paraffins on a cobalt catalyst. Adding HBr was found to promote the formation of iso-paraffins on an iron catalyst.

Published: November 2022

Conventional petroleum-based refining of fuel for the transport industry faces the challenges of a large amount of CO2 emission and limited reserves. There is an urgent need for greener and more sustainable production, and biomass is a promising renewable carbon-based feedstock to replace conventional petroleum. Fischer–Tropsch synthesis offers a feasible method to convert biomass into a wide range of hydrocarbons, which can be further refined into fuels used in transportation vehicles, including motor-gasoline, diesel and jet fuel. The detailed specifications of the transportation fuels are detailed in this chapter to provide a better understanding of the refining requirements. The corresponding refinery flow sheets are also provided. It can be concluded that the refinery design used involves trade-off to balance a number of factors.

Extending the LQR to the design of PID type‐ii and type‐iii control loops
Authors: Liu Chao , Duan QianWen , Zhang Chao , Luo Yong , Qiu XiaoXia , Xia WenQiang , Li Hong , Mao Yao
Published: November 2022

This paper concerns the improvement on Proportional‐Integration‐Derivative (PID) control for standard second‐order plus time‐delay systems (SOPTD). To achieve higher tracking precision and stronger disturbance rejection, a PID type‐ii and type‐iii control‐loops design method based on the combination of the linear quadratic regulator (LQR) and dominant pole configuration technology is proposed in this paper. The PID type‐ii control loop is capable of achieving perfect tracking of step and ramp reference signals with zero steady‐state position and velocity error. The PID type‐iii control loop is capable of achieving perfect tracking of step, ramp and parabolic reference signals with zero steady‐state position, velocity and acceleration error. The effectiveness of the proposed PID type‐ii and type‐iii controller parameters tuning rules has been demonstrated via simulation of over‐damped, critical‐damped and under‐damped systems. To be specific, compared with the PID type‐i control loop, rise time, settling time and disturbance rejection property of the system have been significantly improved while realizing faster reference signal tracking. Finally, the effects of non‐dominant pole on the stability and robustness of PID type‐ii and PID type‐iii closed loop systems have also been discussed.
A novel adaptive δ‐generalised labelled multi‐Bernoulli filter for multi‐target tracking with heavy‐tailed noise
Authors: Gu Peng , Jing Zhongliang , Wu Liangbin
Published: November 2022

Conventional δ‐generalised labelled multi‐Bernoulli filter (δ‐GLMB) cannot deal with the problem of the heavy‐tailed process noise and measurement noise. In order to solve this problem, an adaptive δ‐GLMB approach based on minimising Kullback‐Leibler Divergence (KLD) is proposed in this study. The inverse wishart and Student‐t mixture is used to approximate the joint posterior distribution of process noise covariance and measurement noise covariance together with multi‐target state, and the multi‐target state and noise parameters are jointly estimated by minimising the KLD. The simulation results show that the proposed approach is robust to multi‐target tracking for condition with heavy‐tailed process noise covariance and measurement noise covariance. Accurate target number and target state estimation are obtained by effectively estimating the process noise covariance and measurement noise covariance.

Published: November 2022

In this work an inverted metamorphic four junction (IMM4J) solar cell with 30.9% conversion efficiency in beginning of life conditions under the AM0 (1367 W/m2) spectrum is presented. Additionally, our newest improved IMM3J cell, consisting of Ga0.51In0.49P/GaAs/Ga0.73In0.27As subcells, with 30.6% efficiency is also shown. The IMM4J solar cells consist of Al0.05Ga0.46In0.49P/Al0.14Ga0.86As/Ga0.89In0.11As/Ga0.73In0.27As subcells and are epitaxially grown by metal organic vapor phase epitaxy (MOVPE) on a GaAs substrate. These IMM solar cells achieve power-to-mass ratios of 3 W/g or more, which is more than three times higher than standard germanium based triple or four junction space solar cells. The losses in comparison to the simulated near-term potential efficiency of 33.8% for the IMM4J are analyzed in detail. Furthermore, the irradiation behavior for 1 MeV electron fluences of 1 × 1014 e−/cm2 and 2.5 × 1014 e−/cm2 for the IMM4J cells was investigated. A roadmap to further develop this concept towards an IMM5J with a realistic begin of life (BOL) efficiency potential of 35.9% under AM0 is presented.

Authors: Purnomo Aris Rudi , Subekti Hasan , Mahdiannur Muhamad Arif
Published: November 2022

This study aimed at mapping scientific ideas and conceptual knowledge and expectation of the preservice science teachers (PSTs) towards educational research in SDGs context. Analysis of PSTs’ articles and structured interview were performed to gather the information from 13 participants involved in this research. The data were analysed descriptively with the aid of NVivo 12 plus software. Three dimensions of analysis were carried out consisting of the definition, the importance, and the expectation of SDGs. The results indicate that PSTs put their ideas mostly on learning media, learning model, infrastructure, and teacher competencies. In terms of conceptual knowledge of SDGs, PSTs view SDGs as a set of continuous improvement of resources that should accommodate student skills, technology, knowledge, attitude, resources, research, and equality for creating quality education. These were gained after the PST involved in certain activities of teaching practices and managing references to accomplish their manuscript during Science, Environment, Technology, and Society (SETS) course. As a result, the degree of understanding is inherently related to the educational problems in which they were engaged to initiate solutions.

Authors: Fadhilah Nurul , Ahmadi Khaeru
Published: November 2022

Language as a signifier of cultural identity can be seen from the use of its lexicon, one of which is the color lexicon. This study aimed to examine the cultural factors of the formation of the color lexicon in the Madurese language using an anthropological linguistic approach. This research was qualitative descriptive with ethnographic methods and ethnoscience analysis models in order to find cultural themes. The results showed that the color lexicon in the Sumenep dialect of Madurese language was formed due to four cultural factors, including 1) the closeness of the Madurese community to nature, (2) the livelihoods of the Madurese community, (3) the Islamic spirituality of the Madurese community, and (4) the traditions of the Madurese community. These four factors prove that humans tend to borrow or refer to objects that areoften found around them to describe a specific color.

Published: November 2022

Diagnostic tests that have developed so far are used to determine whether students have misconceptions or not, even though through this test (in the form of multiple-choice tier test) it still has disturbing factors. This factor comes from the students themselves, the trial-and-error factor. Therefore, to strengthen the identification of students’ conceptions, an instrument is needed. The development of an answer argumentation instrument aims to ascertain whether students have experienced misconceptions. The answer argumentation instrument refers to the diagnostic four tier test instrument that has been developed by the researcher. In this study, the development of the instrument was implemented for students who were programming the Chemical Kinetics course. The answer argumentation instrument was validated by 5 raters to obtain content validity and construct validity data. The validation results show that the answer argumentation instrument as an instrument to strengthen the identification of students’ conceptions is valid in terms of content and constructs. The instrument can be used to strengthen the conclusions of grouping students based on their conceptions.

Preservice Teachers in Real-world Problem-Posing: Can They Turn a Context into Mathematical Modelling Problems?
Authors: Kohar Ahmad W. , Hidayat Dayat , Prihartiwi Nina R. , Palupi Evangelista L.W.
Published: November 2022

While problem-posing respecting real-world situations can be a promising approach for fostering modelling competence, research on modelling through problem posing is scant. This present paper aims to characterize the mathematical tasks designed by prospective teachers regarding the criteria of a modelling problem. Data were collected from fifty mathematical tasks posed by twenty-five preservice teachers as participants at a public university in Surabaya, Indonesia, within a summative test of an assessment course.The problem-posing task asked the participants to pose two different mathematical tasks from a given realworld situation. To analyze, the participants’ responses were coded as solvable or unsolvable tasks and then further coded regarding two aspects of modelling problem i.e., connection to reality and openness of a problem. Our analysis revealed that the participants tended to pose problems with authentic connections rather than artificial connections to reality. However, only a few of the posed problems were indicated to promote openness in terms of either various mathematical models or an unclear initial state, which is the crucial indicator of a modelling problem. Implications regarding modelling competence via problem-posing in preservice teacher education are discussed.
