  1. 1. Life Cycle Perspective on School Buildings’ Energy Retrofitting

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Maryam Kafashtehrani; [2022]
    Keywords : School; building; LCA; IDA-ICE; energy retrofitting; insulation; ventilation; photovoltaic; PV; GHG;

    Abstract : The building sector contributes substantial energy consumption and greenhouse gas (GHG) emissions. Energy efficiency is the main driver for the mitigation of climate change. Schools are placed with high energy consumption and GHG emitting. READ MORE

  2. 2. Closed-loop control and data- recording of a modular-multilevel converter (MMC)

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

    Author : Longgang Su; [2022]
    Keywords : Modular multilevel converters MMCs ; filed programmable gate array FPGA ; direct memory access DMA ; energy closed-loop control; data recording; ethernet.; Modulära multilevel-omvandlare MMC ; filed programmeable gate array FPGA ; direkt minnesåtkomst DMA ; energistyrning med sluten slinga; datainspelning; ethernet.;

    Abstract : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. READ MORE

  3. 3. Evaluation of Generic GraphQL Servers for Accessing Legacy Databases

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Muhammad Ismail; [2022]
    Keywords : GraphQL; GraphQL vs REST; PostGraphile; Hasura; PostgreSQL; Performance Metrics; Throughput; Query execution time; PostGraphile vs Hasura; Latest web technology; Web solutions; communication over internet;

    Abstract : Over a few years back, REST APIs were considered standard web APIs, which nowhave a strong competitor. REST APIs provide some excellent features like stateless serversand structured access to resources. However, over time, it doesn’t offer flexibility withthe access of data and client changing requirements. READ MORE

  4. 4. Intercorrelation between sound design, binaural and non-binaural audio systems : Effects on general vertical localization precision and reaction time in a non-visual directional choice task 3D game

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : David Baker; [2022]
    Keywords : Spatialization; binaural synthesis; HRTF; stereo; 3D audio; videogames; ASC; Auditory spatial schema; Head related transfer function;

    Abstract : Spatialization of audio in the vertical plane has historically been limited. Instead, sound designers have used basic DSP to create pseudo height effects to explain the positions of corresponding objects. In recent years, binaural synthesis has become more widespread following an increase in the use of software rendering methods. READ MORE

  5. 5. Electrical control handle for liftingsystem

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

    Author : Elin Lerin; Ulrika Toftered; [2022]
    Keywords : Control handle device; Lifting systems; Load cells; Mechatronics; Manöverhandtag; Lyftsystem; Lastcell; Mekatronik;

    Abstract : The purpose of this bachelor’s thesis is to investigate and construct a computerized electric control handle for a lifting system. The goal is to construct a prototype that can enable lifts with a weightless feeling. Initially, a literature study was conducted to investigate different possible solutions. READ MORE
