  2. 1. Development of voyage optimization algorithms for sustainable shipping and their impact to ship design

    Author : Helong Wang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Expected time of arrival ETA ; Ship safety; Sustainable shipping; Metocean forecast; Voyage optimization algorithms.; Dijkstra’s algorithm; Genetic algorithm; Energy efficiency;

    Abstract : The environmental impacts from shipping and the societal challenges of human and property losses caused by ship accidents are pressuring the shipping industry to improve its energy efficiency and enhance ship safety. Voyage optimization is such an effective measure that has been widely adopted in today’s shipping market. READ MORE

  4. 2. Theoretical prediction of ionisation properties of proteins

    Author : Assen Koumanov; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : This work emphasises on elaboration of improved theoretical and computational methods for determination of protonation/deprotonation equilibria in proteins. It also aims to contribute for a better understanding on atomic level of ionisation properties of proteins and their role in structure-functional relationship. READ MORE

  5. 3. Optimization of Compressive Crushing

    Author : Elisabeth Lee; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cone Crusher; Modeling; Compressive Crushing; Implementation; Optimization;

    Abstract : With almost all infrastructures being dependent on the supply of crushed rock materials,minerals, and ores, it is fair to say that the foundation of modern society is literally built uponthese materials. As society continues to develop and standards of living progressivelyincrease, the subsequent growing demand for crushed rock materials, minerals, and ores willresult in a need for improving the performance and efficiency of rock crushing equipment.

  6. 4. Electromagnetic Modelling of Power Transformers for Study and Mitigation of Effects of GICs

    Author : Seyedali Mousavi; Göran Engdahl; Ebrahim Rahimpour; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transformer; hysteresis; DC magnetization; GMD; GICs; FEM; reluctance network method; low frequency transients; core losses; winding losses; eddy current losses; transformator; hysteresis; DC; likströmsmagnetisering; GMD; GIC; FEM; reluktansnätverksmodell; lågfrekventa transienter; kärnförluster; lindningsförluster; virvelströmsförluster; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Geomagnetic disturbances that result from solar activities can affect technological systems such as power networks. They may cause DC currents in power networks and saturation of the core in power transformers that leads to destruction in the transformer performance. READ MORE

  7. 5. Simulation and Estimation of Diffusion Processes : Applications in Finance

    Author : Carl Åkerlindh; Finansiell matematik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Diffusion processes; Kalman filter; Uncented Kalman filter; EM algorithm; Kernel estimation; Bandwidth selection; Multilevel Monte Carlo; Simulated maximum likelihood estimation; Julia language;

    Abstract : Diffusion processes are the most commonly used models in mathematical finance, and are used extensively not only by academics but also practitioners. Nowadays a wide range of models, that can capture many of the effects observed in financial markets, are available. READ MORE
