Wind turbines can be a suitable solution for supplying power. Offshore wind turbines have the potential to generate large amounts of electricity, taking advantage of the strong and consistent winds found at sea. This can help meet growing energy demand and contribute to the decarbonization of the power sector. However, due to environmental conditions, a range of unpredictable events such as lightning, stormy weather and rough seas can have serious consequences on a wind turbine, potentially resulting in defective rotor blades, tower movements or, in the worst-case scenario, complete failure or collapse of the wind turbine. So, the control and maintenance of wind turbines is an important research topic. With the advancements in technology, such as artificial intelligence, machine learning, and advanced control algorithms, intelligent control systems are becoming more sophisticated and capable of optimizing the operation of wind turbines. These systems can efficiently manage maintenance and ensuring stability and reliability.  报告人简介:Ardashir Mohammadzadeh received his Ph.D. in electrical engineering-control in November 2016 from the University of Tabriz, Iran.  From 2017-2022, he was working at University of Bonab, Bonab, Iran as an assistant/associate professor.

However, compared with wind or solar energy, wave energy is still recognized as a form of untapped renewable energy resource. To accelerate the development of wave energy converters, it is of great importance to further develop numerical modeling since it is normally associated with remarkably lower cost than experiments. The most commonly utilized numerical models in wave energy converter modeling can be categorized as frequency-domain approach and time-domain approach. But they are either limited to linear assumptions or with high computational load, which hinders the extensive application to iteration and detailed optimization of wave energy converters. In this talk, a unique modeling approach for wave energy converters is introduced, that is spectral-domain approach. This approach covers both adequate accuracy and high computational efficiency. The development of this modeling technique to suit a set of inherently related nonlinear effects in the operation process of wave energy converters is covered. Furthermore, a few of typical application scenarios of spectral domain modeling are presented.     报告人简介：谭戬博士本硕毕业于武汉理工大学，博士毕业于代尔夫特理工大学，现于VOSTA LMG公司担任研发工程师。近年来，谭戬博士以第一作者或通讯作者在本领域主流期刊发表论文8篇。其代表性成果为:首次完整将地波浪能装置的非线性工作过程用谱域模型描述并验证。该成果将波浪能传统数值模型的计算速率加快了上千倍，此成果作为特邀论文发表于国际期刊“应用海洋研究”。主要研究方向是水动力分析、非线性动力学，线性电机模型，波浪能装置优化与设计等。 学术报告4 讲座题目：Recycling of waste materials to make suitainable and durable concrete 内容摘要:As one of the most used commodities in the world, concrete is well-known for being a huge CO2 emitter due to the use of Portland cement. Portland cement production contributes to around 8% of global carbon dioxide emissions, highlighting the urgency to develop lower carbon binders. This presentation introduces two studies developing low carbon concrete based on the valorization of waste materials in Singapore, which involves the practical application of traditional waste and the fundamental study of emerging waste. Firstly, for traditional waste, waste glass was collected and processed into powder to replace cement. The glass powder concrete with 20% glass powder achieved comparable strength, improved durability, and decreased CO2 emission and cost when compared to normal concrete. Some glass powder concrete products developed were successfully applied in some sites of NUS campus and are under study for further applications. Secondly, for emerging waste, with the global trend of adopting electric vehicles （EVs）, battery waste will surge in the near future. Lithium iron phosphate （LFP） battery is one of the dominant batteries for EVs. Its recycling will leave some less valuable residues which consist of mainly iron phosphate （FP）. The explorations indicated the great potential of using the waste in the cement and concrete industry. The battery waste can partially replace cement. A suitable dosage of the battery waste （e.g. 5%） makes the blended cement binder have refined pore structure and enhanced 7- and 28-day compressive strength. Additionally, the battery waste can be developed as concrete retarders. The significant retarding effect of the battery waste was confirmed by multiple techniques such as heat of hydration tests, SEM morphology observations and quantitative XRD analysis. The FP waste can chemically react in cement binder, refining microstructure and binding the Fe and P in concrete to avoid negative environmental impacts. 报告人简介:Luo Zhiyu  has a research background in the field of structural engineering and material science.

This research aims to advance the control algorithms and strategies specifically tailored for mitigating pitching and rolling motions in floating offshore wind turbines. The study employs a comprehensive approach, integrating classical Lagrangian principles for analytical modeling of in-plane swing vibrations in the suspended structure. The focal point of investigation lies in the development and implementation of an innovative control system, known as the Active Rotary Inertia Driver （ARID）, which actively manages rotary inertia to enhance stability and performance. The research further involves the linearization of equations of motion to facilitate the application of classical linear control algorithms, including the Linear Quadratic Regulator （LQR）. The versatility and adaptability of the proposed control strategy are analyzed, considering varying environmental conditions and operational scenarios. The simulations are aimed to validate the effectiveness of the control strategies in reducing pitching and rolling motions, optimizing power production, and minimizing structural loads. In addition to theoretical and numerical investigations, the study explores the potential for experimental validation using scaled models from existing floating offshore wind turbines. Insights gained from this research will contribute to the advancement of control systems tailored for the unique challenges posed by the offshore wind energy sector, fostering increased efficiency, reliability, and longevity of floating wind turbine systems.  报告人简介:Zeshan Alam commenced his academic journey with a B.Sc. in Civil Engineering from the University of Engineering and Technology, Peshawar, in 2010, followed by MS in Structural Engineering from the National University of Sciences and Technology, Islamabad, in 2012.

Usually during heavy winter, for countries like Europe, North American and Northern Asia, these offshore platforms suffer ice pressure due to ice deposition. This becomes the main environmental load. A finite element model can be used for structural analysis of the structure. Based on this structural analysis results, an SHM system can be designed which includes sensory, data acquisition, data communication, data management, module for structural analysis and warning systems. Facilities to operated on-line and controlling remotely through internet can be achieved. Immediately warning can be received from the receiver that emits signals for critical change in stress, loads and fatigue accumulated damage that is expected during harsh winter. 报告人简介:Siva Avudaiappan is presently working as Associate Professor at the Departamento de Ciencias de la Construcción, Facultad de Ciencias de la Construcción y Ordenamiento Territorial, Universidad Tecnológica Metropolitana, Santiago, Chile.
