  1. 1. Phonons in 1-D Graphene Nanoribbons Probed with Raman Spectroscopy : Unraveling Fundamental Properties in 9-atom-wide Graphene Nanoribbons

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

    Author : Angel Victor Labordet Alvarez; [2023]
    Keywords : 9-armchair graphene nanoribbons 9-AGNRs ; polarization Raman Spectroscopy PRS ; temperature-dependent Raman spectroscopy; thermal sensitivity; thermal stability; Grüneisen parameter χ ; anharmonicities; vibrational modes G; D; RBLM .; 9-armchair grafen nanoribbons 9-AGNRs ; polarisation Raman spektroskopi PRS ; temperaturberoende Raman spektroskopi; termisk känslighet; termisk stabilitet; Grüneisen parameter χ ; anharmoniciteter; vibrationslägen G; D; RBLM .;

    Abstract : This report employs advanced Raman spectroscopy techniques to investigate the fundamental properties of 9-AGNRs comprehensively. It is divided into two main sections addressing distinct aspects of 9-AGNR behavior. In the first section, Polarization Raman spectroscopy (PRS) probes phonon mode symmetries in 9-AGNRs. READ MORE

  3. 2. The temporal side of pull request acceptance

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

    Author : Balthazar West; [2023]
    Keywords : Pull requests; GitHub; code review; machine learning; survey; Pull requests; GitHub; kodrecension; maskininlärning; enkät;

    Abstract : The contemporary way of contributing to open-source software is through online platforms. GitHub is the most widely used platform for this purpose. On GitHub, users can suggest improvements to projects by opening a pull request (PR), taking on the role of the submitter. READ MORE

  4. 3. Extracting Transaction Information from Financial Press Releases

    University essay from Linköpings universitet/Artificiell intelligens och integrerade datorsystem

    Author : Agaton Sjöberg; [2021]
    Keywords : Natural Language Processing; Information Extraction; Named Entity Recognition; Relation Extraction; Latent Structure Refinement; Financial Press Release; Insider Transaction;

    Abstract : The use cases of Information Extraction (IE) are more or less endless, often consisting of a combination of Named Entity Recognition (NER) and Relation Extraction (RE). One use case of IE is the extraction of transaction information from Norwegian insider transaction Press Releases (PRs), where a transaction consists of at most four entities: the name of the owner performing the transaction, the number of shares transferred, the transaction date, and the price of the shares bought or sold.

  5. 4. Cultural Ecosystem Services on the university campus - A student-centered approach to assess psychological and climate-related benefits of cultural ecosystem services on the university campus.

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Christoffer Hahn; [2021]
    Keywords : cultural ecosystem services; environmental appraisal; university campus; green areas; climate change adaptation; climate change mitigation; urban heat island effect; perceived biodiversity; perceived restorativeness; NCP; multifunctionality.; Earth and Environmental Sciences;

    Abstract : With climate change being one of the largest worldwide challenges of our time, it is important to prevent the loss of natural ecosystems that can act to mitigate climate change. Moreover, ensuring that urban areas are designed for human needs in conjunction with climate change adaptation/mitigation for a sustainable environment is crucial. READ MORE

  6. 5. Positioning in Non-Terrestrial Networks

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

    Author : Soha Emara; [2021]
    Keywords : positioning; 5G; satellite; NTN; Technology and Engineering;

    Abstract : In 5G communications, Non-terrestrial Network (NTN) is envisioned to complement Terrestrial Network (TN) to increase network availability, scalability and continuity. Positioning of User Equipment (UE) is critical for the operation of NTN. Currently, NTN uses Global Navigation Satellite System (GNSS) for positioning. READ MORE
