    Abstract : Organic solar cells (OSCs) based on non-fullerene acceptors (NFAs) have attracted a great deal of attention in recent years due to their rapidly increasing efficiency and enormous potential. In this work, the optical and electronic properties of systems containing the very promising non-fullerene acceptor PYT have been thoroughly studied with the use of the density functional theory (DFT) and the time-dependent density functional theory (TDDFT).

  3. 12. An implementation of an autonomous IoT system for real-time water quality monitoring with 4G and satellite connection : CatFish - Embedded systems

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Johan Elfing; Daniel Persson; [2022]
    Keywords : CatFish; Embedded System;

    Abstract : This thesis is about implementing an Internet of Things system for measuring water quality in rivers and other aquatic environments with an autonomous water drone, where the data from various components are collected and sent wirelessly to the database in real-time. A Raspberry Pi is connected to the internet through a 4G modem and a wireless satellite communication connection called RockBlock for emergency calls and notifications. READ MORE

  5. 14. Multiscale numerical approximation of morphology formation in ternary mixtures with evaporation : Discrete and continuum models for high-performance computing

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Mario Setta; [2021]
    Keywords : ;

    Abstract : We propose three models to study morphology formations in interacting ternary mixtures with the evaporation of one component. Our models involve three distinct length scales: microscopic, mesoscopic, and respectively, macroscopic. READ MORE

  6. 15. Numerical Analysis Of 2D And 3D losses In Organic Rankine Cycle Turbine

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Abstract : World resources are becoming more and more scarce due to the increasing demand. Hence, the industry is moving towards sustainable development in order to suffice the needs of the future generations. Electricity is one such resources that account for 90% of the daily utility. In Sweden alone 378 TWh of electricity is consumed over a year. READ MORE
