   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Julia Ladefoged; [2023-08-18]
   Keywords : ;

   Abstract : Lake ice have been utilized by humans through centuries, as transportation routes and recreational activities to name a few (Sharma et al., 2019). Despite our frequent usage of lake ice there is a lack of extensive knowledge of it. READ MORE

3. 2. Enhancing the Decoding of Short LDPC Codes with Stochastic Sequences

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

   Author : Yuyuan Gu; Haien Li; [2021]
   Keywords : 5G; channel coding; LDPC codes; stochastic decoding; stochastic computation; Technology and Engineering;

   Abstract : Low-Density Parity-Check (LDPC) codes are one of the most popular codes used in nowadays’ communication due to their high coding efficiency at low decoding complexity. With these characteristics, LDPC codes are suitable for high-speed information transmission systems. READ MORE

4. 3. Image analysis tool for geometric variations of the jugular veins in ultrasonic sequences : Development and evaluation

   University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

   Author : Arvid Westlund; [2018]
   Keywords : active contour; ultra sound; ultrasonic; image analysis; internal jugular veins; snake;

   Abstract : The aim of this project is to develop and perform a first evaluation of a software, based on the active contour, which automatically computes the cross-section area of the internal jugular veins through a sequence of 90 ultrasound images. The software is intended to be useful in future research in the field of intra cranial pressure and its associated diseases. READ MORE

5. 4. Near-local density approximation approach to one-dimensional lattice systems

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

6. 5. Preparation and characterization of nanocellulose from wheat bran

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Claes Nilsson; [2017]
   Keywords : Spherical nanocellulose; Nanocellulose; Wheat bran; Cellulose; Renewable; chemical engineering; kemiteknik; Technology and Engineering;

   Abstract : Nanocellulose is being studied to a great extent around the world as it has great potential and many possible applications, for example, as an additive in greener polymers in a world where the need for replacements for fossil fuel based polymers increase. Different sources of cellulose are being considered for the production of nanocellulose as this can add value to what otherwise often is a by-product. READ MORE
