1. 1. Short-horizon Prediction of Indoor Temperature using Low-Order Thermal Networks : A case study of thermal models for heat-system control applications

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Jonas Cederberg; [2023]
   Keywords : Lumped Parameter Thermal Network; Resistance-Capacitance model; Parameter estimation; Modelling of Dynamical Systems; Thermal modelling; Temperature Prediction; Termiskt nätverk med klumpade parametrar; Mostånds-kapacitans modell; Parameterestimering; Modellering av dynamiska system; Termisk modellering; Temperaturprediktion.;

   Abstract : Optimizing and controlling the heating systems in buildings is one way to decrease their load on the power grid, as well as introduce load flexibility to be used in Demand Response (DR) applications. A requirement in occupied buildings is that the thermal comfort of the residents is guaranteed, making the optimization of heating systems a constrained problem with respect to indoor temperature.

3. 2. Implementation and study of boundary integral operators related to PDE:s in the plane

   University essay from Lunds universitet/Matematik LTH

   Author : Erik Andersson; [2023]
   Keywords : Boundary integral equation; Singular integral operator; Product integration; Close evaluation; Numerical integration; MATLAB; Mathematics and Statistics;

   Abstract : The method of solving boundary value problems of partial differential equations numerically by first reformulating the problem as a boundary integral equation has many advantages over other methods, but also some unique difficulties. Some of these difficulties stem from problems in evaluating singular or nearly singular integral operators, and solving these difficulties is an active field of research. READ MORE

4. 3. EVALUATION OF MULTI-ZONE MODELLING FOR FIRE RISK ASSESSMENT IN TUNNELS

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Annachiara Nardone; [2023]
   Keywords : tunnels; tunnel fires; multi-zone modelling; Technology and Engineering;

   Abstract : Abstract Tunnels are one of the most complex and delicate elements of the road system. Assessing fire behaviour and fire severity remains the biggest source of uncertainty in risk assessment and is an essential step in the tunnel design process. READ MORE

5. 4. Physics-Enhanced Machine Learning for Energy Systems

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Henrik Lindström; Emil Sundström; [2022]
   Keywords : Technology and Engineering;

   Abstract : Building operations account for a large amount of energy usage and the HVAC (Heating, Ventilation and Air Conditioning) systems are the largest consumer of energy in this sector. To reduce this demand, more energy-efficient control algorithms are implemented and a popular choice for a controller is the model predictive control. READ MORE

6. 5. Modelling of a Heat Conduction Calorimeter Used in Cement Plant Automation

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Hassan Alzeidi; [2022]
   Keywords : Technology and Engineering;

   Abstract : A model is used to describe a system physically or mathematically and to give information about changes in the system variables. Physical knowledge about the system and its quantities can be useful to build a physical model obeying the laws of nature. READ MORE
