1. 1. Comparison of spatial partitioning data structures in crowd simulations

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

   Author : Jakob Kratz; Viktor Luthman; [2021]
   Keywords : Radius Search; Spatial Partitioning; Agent- Based Simulation; Boids; Grid; Kd- Tree; Quadtree; Maximum Velocity; Radius Search; Spatial Partitioning; Agent- Based Simulation; Boids; Grid; Kd- Tree; Quadtree; Maximum Velocity;

   Abstract : This report investigates how the construction and query time of multiple spatial partitioning data structures is impacted by spatial distribution of and number of agents in a crowd simulation. In addition a method is investigated for updating the data structures less frequently at the cost of increasing the radius queried, without affecting the correctness of the queries. READ MORE

3. 2. Performance Evaluation of distributed Solar PV Installations

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : MUHAMMAD AMMAR KHAN; FATIMA NAVEEN; [2020]
   Keywords : ;

   Abstract : Utilization of photovoltaic (PV) cells to generate electricity from solar energy is becoming an increasingly popular source of renewable energy in this era of energy transitions. Adoption of ingenious techniques to increase PV systems’ performance and with the arrival of data analytics for efficient management of energy systems, an opportunity of using statistical models to develop mechanisms for performance evaluation of distributed Solar PV systems is present.

   Keywords : Slip efficiency; sliding mode controller; sliding mode observer; articulated vehicles; wheel loader dynamic.; Slipeffektivitet; sliding mode regulator; sliding mode observerare; ledat fordon; hjullastarens dynamik.;

   Abstract : This report evaluates the option of using an equal slip controller, an effective rolling radius and rolling resistance force observer in a 4WD wheel loader. The vehicle studied is an under development- vehicle designed by Volvo CE. READ MORE

5. 4. Mapping the present-day chemical abundance structure of the Solar neighbourhood: O & Si

   University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Kristiina Verro; [2017]
   Keywords : astrophysics; stellar spectroscopy; abundance analysis; solar neighbourhood; massive stars; Galaxy; Physics and Astronomy;

   Abstract : Context. Large scale chemical abundance gradients in the Galactic disks, small-scale abundance structures, and the mean chemical abundance values in the Solar vicinity, are important constraints to Galactic chemo-dynamical formation and evolution models. READ MORE

6. 5. Investigation of the transient nature of rolling resistance on an operating Heavy Duty Vehicle

   University essay from Umeå universitet/Institutionen för fysik
