1. 1. LEO Satellite Connectivity for flying vehicles

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Jinxuan Chen; [2023]
   Nyckelord :LEO satellite network; satellite connectivity strategy; Nash-SAC; flying vehicles; LEO:s satellitnät; Strategi för satellitanslutning; Nash-SAC; flygande fordon;

   Sammanfattning : Compared with the terrestrial network (TN), which can only support limited covered areas, satellite communication (SC) can provide global coverage and high survivability in case of an emergency like an earthquake. Especially low-earth orbit (LEO) satellites, as a promising technology, which is integral to achieving the goal of global seamless coverage and reliable communication, catering to 6G’s communication requirements.

3. 2. Proposal for revised criteria for daylight provision for the European Daylight Standard EN 17037:2018+A1

   Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

   Författare :Zhengyu Jin; Xintong Chen; [2023]
   Nyckelord :Daylight; Residential; European Standards; Compliance; Spatial Daylight Autonomy; Technology and Engineering;

   Sammanfattning : The European daylight standard EN 17037 was first introduced in 2018 with the aim of encouraging building designers to evaluate and ensure adequate daylight provision in buildings. However, experience has shown that the standard’s criteria are generally perceived to be too challenging to achieve. LÄS MER

4. 3. House price and fertility behavior among different families - Empirical study from CFPS data

   D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Författare :Huichan Chen; [2023]
   Nyckelord :House Price; Fertility Rate; Gender Effect; Birth Plan Policy; One Child Policy;

   Sammanfattning : This paper uses panel data from the China Family Panel Studies (CFPS) to examine the relationship between housing prices and fertility behavior in China, this paper analyzes sample data from 2014, 2016 and 2018 and uses Probit model and the logit model to study how house price affects fertility behavior among different families, furthermore, after the removal of One Child Policy, how the fertility behavior would react to house price. The study found that rising housing prices have a significant negative impact on fertility behavior, and that this negative impact persists even when using instrumental variables to control for endogeneity.

5. 4. Supersymmetry in Quantum Mechanics

   Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

   Författare :Ludvig Chen; [2023]
   Nyckelord :Quantum Mechanics; Supersymmetry; Witten Index; Morse Theory;

   Sammanfattning : The introduction of supersymmetry has led to great progress in the study of quantum field theories. Notably, with supersymmetry, properties of a quantum field theory can be computed with higher precision than what would otherwise be possible. In this project, we investigate supersymmetry in the context of quantum mechanics. LÄS MER

7. 5. The Rebellion Power of the F-word in Modern Songs : A Corpus-Based Discourse Analysis

   Kandidat-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

   Författare :Yulong Chen; [2023]
   Nyckelord :F-word; rebellion power; modern songs; corpus linguistic analysis;

   Sammanfattning : Abstract: In this thesis, the general use and specific instances of F-words in modern music lyrics have been studied based on the corpora extracted from songs in Billboard year-end charts from 2013 to 2022, which represented the most popular songs in English-speaking countries. By screening the actual meaning and contexts of those F-words in the lyrics, I extracted those special instances in which F-words were used to express rebellious feelings to challenge social norms and fight against authority powers.
