We present a stochastic mixed-integer model for the optimization of joint trade in the day-ahead and balancing markets. The model takes the perspective of a risk-neutral price-taking hydropower producer for a one-day planning horizon. The model is used to study the value of trading in both markets as...

...have experienced significant growth in the past 20 years. During this period, the solar industry has witnessed technological advances, cost reductions, and increased awareness of renewable energy’s benefits. As more than 90% of the commercial solar cells in the market are made from silicon, in this work...

...new concept to improve the assessment of ships’ energy efficiency and offer benchmarking options among similar ship types and sizes. This work extends previous research to consolidate the methodology, bring more comprehensiveness, and provide a more holistic assessment of these operational cycles. The...

...pollution in the oceans, including both macro- and microplastics, is well-documented and has a number of adverse effects on nature, coastal communities and the maritime economy. For example, wildlife can become entangled in plastics, posing a hazard to shipping and contributing to the contamination of fish...

...report provides an overview over the most common used NDT methods and sensors for inspection and monitoring of existing concrete structures. The methods are briefly described with regard to their working principle and the parameters and properties of concrete structures that can be investigated. NDT methods...

...extraction and Long Short-Term Memory (LSTM) networks for temporal modeling. This system achieves a testing accuracy of 95%, aligning with existing benchmarks and demonstrating its robustness to variations in signing styles, orientations, and speeds. While challenges such as data imbalance and misclassification...
