Study of Predictive Control Model for Cooling Process of Mark III LNG Bunker
Authors: Bao Guozhi , Qin Weiguang , Jiang Qingfeng , Pu Chunrong 
Published: September 2024

Abstract
When loading liquefied natural gas (LNG) onto a dual-fuel LNG container ship fuelled by LNG, there is a considerable temperature difference between LNG and the fuel tank at room temperature. The current solution is to pre-cool the tank with LNG through a spray line but the cooling process, if not correctly handled, can result in excessive cooling rates and Boil-Off Gas (BOG), which can expose the tank to increased temperature stress and gas pressure. Therefore, this paper takes the Mark III fuel tank of a specific type of LNG container ship as the object and realises a real-time predictive control system by writing a UDF (User Defined Function) to simulate and analyse the influence of LNG spray rate on the change of cooling effect, cooling time and cooling cost under the unidirectional LNG spray cooling mode. Compared with the results of the fuel tank gas experiment, the deviation of numerical model simulation results is less than 5%. Under the same cooling rate, the real-time control scheme can achieve a more uniform cooling rate and reduce the total LNG consumption by 25%. With the increase in LNG cooling rate, the cooling time, LNG usage, and the total BOG exhaust volume all decrease; however, the decreased range gradually decreases as well. The results of this paper provide parameters and suggestions for optimising and improving the LNG fuel tank cooling monitoring and control system.

Abstract
This article analyses the effects of deformation on the structure of CMnSi steel at various deformation levels. After hot forging, the structure of CMnSi steel comprises coarse-sized alpha and pearlite particles. The average grain size of steel after forging was 100 μm. After hot rolling, the grain size gradually decreases, with the average size of the ferrite and pearlite grains measured as 60 μm. After that, CMnSi steel was subjected to cold deformation at levels of 40%, 60%, and 80%. The grain size of the CMnSi steel sample after 80% cold deformation reached level 7, corresponding to about 25 μm. For a deformation level of 40%, the grain size was level 5, corresponding to 40 μm, while a deformation level of 60% produced a grain size of 35 μm, corresponding to level 6. In addition, scanning electron microscopy showed that after 80% deformation, smaller particles with a size of about 5 μm appear inside the parent particles. Moreover, energy-dispersive X-ray spectroscopy analysis revealed the carbide appearance in the form M23C6, with M being a mixture of Fe and Mn. These carbides have a fine size of about 1–2 μm and contribute to the prevention of particle growth during subsequent heat treatments.

Abstract
Autonomous underwater vehicles are increasingly frequently used in the fields of ocean observation, data collection, and tactical surveillance. Underwater navigation and near real-time communication are the most important factors limiting the performance of these vehicles. In this article, an underwater acoustic communication and positioning system (UACPS) based on heterogeneous gliders is presented. The system consists of an acoustic wave glider and an acoustic underwater glider, and includes an ultrashort baseline and an acoustic modem. The program and communication protocol of the communication and positioning algorithm are independently developed, and the hardware circuit design of the communication and ultra-short baseline positioning, as well as the embedded surface wave gliders and gliders are independently implemented. Sea trial results indicate that the communication distance of the system is more than 3 km and the positioning error is less than 5%. With the further improvement of system performance, the low cost, long time, long distance and near real-time communication characteristics of our UACPS can be used to integrate multiple autonomous unmanned platforms as part of intelligent surveillance robot networks.

Tulisan ini mencoba menelusuri kitab al-Taqyid wa al-Idhah Syarh Muqaddimah Ibn Shalah karya al-Iraqi yang didalamnya terdapat 50 macam cara pentarjihan dalam menyelesaikan Muktalif al-Hadis. Dengan mennggunakan kajian pustaka Library Research penulis membaca lebih jauh bagaimana al-Iraqaqi dalam menyelesaikan hadis-hadis yang mukhtalif/bertentangan. HasilnyaAl-Iraqi dalam al-Taqyid wa al-Idhah Syarh Muqaddimah Ibn Shalah memaparkan sekian banyak cara pentarjihan, akan tetapi tidak menjelaskan secara konfrehensif berbagai cara tersebut. Namun setidaknya dengan mengelaborasi beberapa pendapat dari ulama sedikit dapat memahami mukhtalif al-hadis melalui cara pentarjihan yang disodorkan oleh al-Iraqi. Mengkompromikan suatu hadis yang terlihat bertentangan merupakan metode yang lebih baik. Karena dengan itu kita bisa memahami suatu hadis secara lebih dinamis, kontekstual tanpa terjebak dalam pemahaman secara tekstual seperti yang banyak terjadi dalam kehidupan masyarakat.

Published: September 2024

Al-Maududi and Abdullah Saeed are Muslim scholars. He contributed various thoughts in the field of economics, one of which is related to usury and bank interest. But there are differences of opinion between the two. The purpose of this study is to look at the views of Al-Maududi and Abdullah Saeed regarding usury and bank interest. The method used is a literature study with a descriptive qualitative approach. Data sources come from secondary data sources, namely journals and books related to the discussion. The result of the research is that Al-Maududi firmly rejects bank interest because the institution is a source of danger and evil through its influence on human character because it is influenced by the love of money. In addition, Al-Maududi stated that there is an element of injustice in bank interest and it is clearly prohibited in Islam. While Abdullah Saeed views the prohibition of usury based on the historical situation and conditions behind the revelation of the verse, so related to bank interest Abdullah Saeed argues that bank interest is not included in usury because the context of usury in ancient times is very much different from usury today.

Published: September 2024

Indonesia berkomitmen untuk menyukseskan Sustainable Development Goals (SDGs) sebagai bagian dari upaya pembangunan ekonomi berkelanjutan yang juga merupakan bagian dari komitmen global. Tulisan ini bertujuan untuk menganalisis sejauh mana keberhasilan pemerintah dalam menerapkan program SDGs, dengan focus pada tujuan-tujuan terkait kesejahteraan. Selain itu, penulis juga akan mengeksplorasi relevansi penerapan SDGs di Indonesia dari perspektif ekonomi Islam. Metode penelitian yang digunakan adalah Sistematic Literature Review, yang merupakan pendekatan sistematis dan terstruktur untuk menilai, menganalisis, dan menyintesis literatur yang relevan dengan topik penelitian. Hasil kajian menunjukkan bahwa aspek regulasi SDGs di Indonesia telah menunjukkan kemajuan signifikan dan relevansi dengan prinsip-prinsip ekonomi Islam. Namun, dalam praktiknya, terdapat berbagai kekurangan dan ketidaksesuaian antara isu kesejahteraan dan tujuan SDGs, terutama dari perspektif ekonomi Islam. Hal ini berkontribusi pada peningkatan kesenjangan sosial di Indonesia dalam sepuluh tahun terakhir. Temuan ini menunjukkan perlunya perbaikan yang signifikan dalam pelaksanaan program SDGs untuk mencapai kesejahteraan yang lebih merata dan adil. Indonesia is committed to the success of the Sustainable Development Goals (SDGs) as part of the sustainable economic development efforts that are also part of global commitments. This paper aims to analyze the extent of the government's success in implementing the SDGs program, focusing on goals related to welfare. In addition, the author will also explore the relevance of implementing the SDGs in Indonesia from an Islamic economic perspective. The research method used is Systematic Literature Review, which is a systematic and structured approach to assess, analyze, and synthesize the literature relevant to the research topic. The results of the study show that the regulatory aspects of SDGs in Indonesia have shown significant progress and relevance to the principles of Islamic economics. However, in practice, there are various shortcomings and mismatches between welfare issues and the goals of the SDGs, especially from an Islamic economic perspective. This has contributed to the increase in social inequality in Indonesia in the last ten years. These findings indicate the need for significant improvements in the implementation of the SDGs program to achieve more equitable and just welfare.
