1. 11. Influence of land cover changes on organic carbon and organic nitrogen concentrations in Swedish rivers

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Julia Iwan; [2021]
   Keywords : Total Organic Carbon TOC ; Total Organic Nitrogen TON ; Land Cover Change; Sweden; WaterBase; Earth and Environmental Sciences;

   Abstract : There is increasing pressure on freshwater systems due to excessive nutrient loading by anthropogenic sources. In Sweden, freshwaters have become browner due to increasing exports of organic matter from soils into streams, rivers, and lakes. READ MORE

3. 12. Microeletromechanical Systems for Tunable Ring Resonators on a Silicon Platform

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

   Author : Chris Phong Van Nguyen; [2021]
   Keywords : Integrated photonics; Silicon Photonics; MEMS; Silicon Photonic MEMS; Ring Resonator; Telecommunications; Integrerad fotonik; Silicon Photonics; MEMS; Silicon Photonic MEMS; Ringresonator; Telekommunikation;

   Abstract : Advancements in photonic integrated circuits, so-called PICs, have progressed fast in the last decades. More complex PICs are getting developed, which are promising in possibly offering advantages like low power consumption and high-performance computing. Re-programmable photonic FPGAs are one of these candidates. READ MORE

4. 13. Evaluation of Attention Mechanisms for Just-In-Time Software Defect Prediction

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

   Author : Abgeiba Yaroslava Isunza Navarro; [2020]
   Keywords : Just-in-Time Software Defect Prediction; Attention Mechanism; Convolutional Neural Network; Feature Extraction; Just-in-Time Software Defect Prediction; Attention Mechanism; Convolutional Neural Network; Feature Extraction;

   Abstract : Just-In-Time Software Defect Prediction (JIT-DP) focuses on predicting errors in software at change-level with the objective of helping developers identify defects while the development process is still ongoing, and improving the quality of software applications. This work studies deep learning techniques by applying attention mechanisms that have been successful in, among others, Natural Language Processing (NLP) tasks. READ MORE

5. 14. Time to change: Analyzing the leadership’s challenges that affect the stakeholders’ co-creation of sense during organizational changes

   University essay from Lunds universitet/Institutionen för strategisk kommunikation

   Author : Diana Lara Del Cid; [2020]
   Keywords : change communication; change management; stakeholder theory; social constructivism; sensemaking.; Social Sciences;

   Abstract : In change management, approaches to handle change have been broader discussed, from a ‘top-down’ outdated method to a ‘bottom-up’ inclusive model. Scholars have discussed the advantages of having an inclusive model which is re-lated to the directional flow of change communication. READ MORE

6. 15. PLL for 5G mmWave

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

   Author : Daniel Bakic; Jinzhuo Wu; [2020]
   Keywords : PLL; 5G-NR; RFIC; beamforming; 22nm FDSOI; charge pump; vco; loop filter; frequency divider; phase detector; phase noise; jitter; Technology and Engineering;

   Abstract : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. READ MORE
