1. 1. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.

   University essay from Uppsala universitet/Strukturkemi

   Author : Ismail Yussuf Hassan; [2023]
   Keywords : graphite; dual-ion battery; parasitic reaction; cathode-electrolyte interface; anion intercalation; concentrated electrolyte; self-discharge; Raman spectroscopy;

   Abstract : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

3. 2. Digital Front End Algorithms for Sub-Band Full Duplex

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

   Author : Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Keywords : Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

   Abstract : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

4. 3. Investigation of the mean photon energy in Kompaneets spectra

   University essay from KTH/Fysik

   Author : Richárd Bagi; [2023]
   Keywords : Astroparticle Physics; Kompaneets equation; Astropartikelfysik; Kompaneetsekvationen;

   Abstract : The Kompaneets equation describes the spectrum formation when hot fermions are injected into an opaque fermion-photon plasma in thermal equilibrium and inverse Compton-scatterings occur. The equation has three free parameters, the initial plasma thermal energy θ_u, the final plasmathermal energy θ_r and the average photon energy gain y_r. READ MORE

5. 4. Paletto: An Interactive Colour Palette Generator : Facilitating Designers’ Colour Selection Processes

   University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Author : Rema Salman; [2022]
   Keywords : Colour-palettes design; Colour extraction; Machine-learning; K-means algorithm; Human-computer interaction; Human-automation collaboration; User experience; User engagement.;

   Abstract : Digital growth and the adaption of internet-based solutions, particularly artificial intelligence and machine learning, have dramatically changed the way design is done today. This rapid change in technology has challenged the level of automation, which influences the human-automation interactions with the available colour-design tools (academic and commercial). READ MORE

6. 5. Eye movement during available Eye Contact, Skewed Visuality and Time Delay in Video Conversation

   University essay from Umeå universitet/Institutionen för psykologi

   Author : Foteini Gkivizini; [2022]
   Keywords : online video call; eye movement; eye tracking; eye contact; online synchronous communication; social breathing; videosamtal online; ögonrörelser; ögonspårning; ögonkontakt; synkron kommunikation online; social andning;

   Abstract : Online conversations via video have nowadays partially replaced face to face contact, and there are some challenges that occur in video conversations, e.g., time delay and the placement of the camera which leads to eliminating the possibility for direct eye contact, and time delay.
