  1. 1. Free cooling and PVT integration in a ground-source heat pump (GSHP) system

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

    Author : Christopher Pourier; [2023]
    Keywords : Ground-source heat pump; borehole; GSHP; photovoltaic thermal collector; PVT; free cooling; Ytjordvärmepump; borrhål; GSHP; solfångare; PVT; frikylning;

    Abstract : The performance of ground-source heat pump (GSHP) systems can be negatively affected over time by soil temperature degradation of boreholes (BH) in heating dominated climates. Land area is scarce in the dense urban environments typical of multi-family houses (MFH) and can lead to accelerated degradation- in tight BH fields. READ MORE

  3. 2. Development of Ferroelectric Hafnium Oxide for Negative Capacitance Field Effect Transistors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Robin Atle; [2019]
    Keywords : Un-doped ferroelectricity; HfO2; Hafnium oxide; ALD; Atomic Layer Deposition; Hysteresis; P-E; polarization; Technology and Engineering;

    Abstract : With the transistor being the workhorse in modern electronics it has been vastly improved since its invention. However, the previous go-to improvement method of scaling it down has reached a dead end. Power dissipation has become a large concern and is in need of a solution. READ MORE

  4. 3. Inclusionary Housing. Analysis of a housing policy in California, USA

    University essay from KTH/Fastigheter och byggande

    Author : Therese Ericsson; [2016]
    Keywords : ;

    Abstract : Sweden is not providing its citizens with sufficient housing anymore. Therefore it is important to consider what can be done to solve the situation. Sweden has the opportunity to learn from and be inspired by how other countries are trying to solve their housing issues. READ MORE

  5. 4. Long Time Integration of Molecular Dynamics at Constant Temperature with the Symplectic Euler Method

    University essay from KTH/Numerisk analys, NA

    Author : Jesper Böjeryd; [2015]
    Keywords : The symplectic Euler method; Ornstein-Uhlenbeck process; Molecular dynamics; Long time integration; Canonical ensemble; Constant temperature; Symplektisk Euler; Ornstein-Uhlenbeck-process; molekyldynamik; integration över lång tid; kanonisk ensemble; konstant temperatur.;

    Abstract : Simulations of particle systems at constant temperature may be used to estimate several of the system’s physical properties, and some require integration over very long time to be accurate. To achieve sufficient accuracy in finite time the choice of numerical scheme is important and we suggest to use the symplectic Euler method combined with a step in an Ornstein-Uhlenbeck process.
