1. 1. Construction and Control of a 3-axisAutomated Liquid Sampling UnitUtilizing Hybrid Stepper Motors

   Master-uppsats, KTH/Mekatronik och inbyggda styrsystem

   Författare :Arvid Bergvall; Pontus Lundman; [2023]
   Nyckelord :Mechatronics; Gantry; Stepper motor; Control; Linear Quadratic Regulator; Adaptive LQI; PID; Mekatronik; Gantry; Stegmotor; Reglerteknik; LQR; Adaptiv LQI; PID;

   Sammanfattning : High accuracy autonomous positioning systems are becoming increasingly important in today’s chemical industry because they can obtain precise experiment results automatically and hence allow lab technicians to focus on other tasks concurrently. One time consuming process is the process of sampling chemical test results into the correct container, especially when the tests are many and infrequent. LÄS MER

   Sammanfattning : The study has investigated what knowledge Swedish upper secondary school teachers, who teach mathematics in the courses 1a, 1b or 1c, express about the teaching of linear functions. Furthermore, the study investigated what teachers believe students need to learn, which instructional activities teachers believe they use and what difficulties teachers perceives in teaching.

   Sammanfattning : With the advances in the telecommunications industry, there is a need to solve the in-band full-duplex (IBFD) problem for antenna systems. One premise for solving the IBFD problem is to have strong isolation between transmitter and receiver antennas in an antenna system. LÄS MER

5. 4. Random Edge is not faster than Random Facet on Linear Programs

   Master-uppsats, KTH/Matematik (Avd.)

   Författare :Nicole Hedblom; [2023]
   Nyckelord :Simplex method; simplex; Random Edge; Linear Programming; Random Facet; randomized pivoting rule; Markov decision process; Simplexmetoden; Random Edge; linjärprogrammering; Random Facet; Markov-beslutsprocess;

   Sammanfattning : A Linear Program is a problem where the goal is to maximize a linear function subject to a set of linear inequalities. Geometrically, this can be rephrased as finding the highest point on a polyhedron. The Simplex method is a commonly used algorithm to solve Linear Programs. LÄS MER

7. 5. Implementation of battery energy storage systems in the Swedish electrical infrastructure

   Master-uppsats, KTH/Kemiteknik

   Författare :Gustav Arnberg; [2022]
   Nyckelord :Battery energy storage systems; BESS; Li-ion batteries; Frequency regulation; Business case; Implementation of battery energy storage systems; Swedish electrical infrastructure; BESS; Li-jon batterier; Frekvensreglering; Affärsfall; Implementering av batterilagringssystem; Svensk elinfrastruktur;

   Sammanfattning : Detta examensarbete utreder den tekniska och ekonomiska passbarheten av batterilagringssystem (BESS) inom den svenska el infrastrukturen. Syftet är att konstruera tre olika affärsfall för att representera den tekniska och den ekonomiska passbarheten av BESS inom den svenska el infrastrukturen, specifikt med uppkoppling mot distributionsnätverket på den regionala nivån, 6 kilovolt till 132 kilovolt (kV).
