  1. 1. BIOPHILIC VALUES AS PATHWAYS TO NATURE CONNECTEDNESS IN UPPER SECONDARY STUDENTS AN ACTION RESEARCH STUDY

    University essay from Göteborgs universitet/Institutionen för didaktik och pedagogisk profession

    Author : Karin Kers; [2022-06-29]
    Keywords : nature connectedness; biophilic values; education for sustainable development; ESD; action research;

    Abstract : Aim: The purpose of the study was to investigate the effectiveness of activating the five biophilic values of emotion, contact, meaning, beauty, and compassion to increase upper secondary students’ nature connectedness and thereby their pro-environmental attitudes and behaviours. Theory: The study was mainly based on the theory of the five biophilic values as pathways to nature connectedness; while also drawing on experiential learning theory, and the EYE for Sustainability Learning Tool.

  3. 2. Leveraging Posits for the Conjugate Gradient Linear Solver on an Application-Level RISC-V Core

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

    Author : David Mallasén Quintana; [2022]
    Keywords : Computer Arithmetic; Conjugate Gradient; Posit; IEEE-754; Floating Point; High-Performance Computing; RISC-V; Datoraritmetik; Konjugerad Gradient; Posit; IEEE-754; Flytande Punkt; Högpresterande Beräkningar; RISC-V;

    Abstract : Emerging floating-point arithmetics provide a way to optimize the execution of computationally-intensive algorithms. This is the case with scientific computational kernels such as the Conjugate Gradient (CG) linear solver. Exploring new arithmetics is of paramount importance to maximize the accuracy and timing performance of these algorithms. READ MORE

    Keywords : cultural governance; collaborative governance; culture for urban sustainability.;

    Abstract : Many scholars and practitioners consider culture an essential ingredient of sustainability that is often underrepresented in the mainstream discourse on sustainability. However, in the last decade, the idea of culture as an agent of transformation capable of driving urban sustainability has gained momentum. READ MORE

  6. 5. Heat Export from Supermarkets : Refrigeration Systems Field Measurements and a Techno-economic Analysis

    University essay from KTH/Energiteknik

    Author : Julia Linnea Hildur Almebäck; Rebecka Magnius; [2022]
    Keywords : Heat Recovery; Heat Export; Supermarkets; Refrigeration Systems; CO2 Transcritical Booster Systems; Energy Efficiency; Värmeåtervinning; värmeexport; livsmedelsbutiker; kylsystem; CO2 transkritiskt boostersystem; energieffektivitet;

    Abstract : Supermarkets have a high energy demand where almost half of the energy is used within the refrigeration system. The refrigeration system utilises a cycle where heat is taken and rejected. The rejected heat could be recovered and utilised for other purposes, such as covering internal heating demand or be exported to other facilities. READ MORE
