1. 1. Disambiguating Italian homographic heterophones with SoundChoice and testing ChatGPT as a data-generating tool

   University essay from Uppsala universitet/Institutionen för lingvistik och filologi

   Author : Matilde Nanni; [2023]
   Keywords : ChatGPT; Homograph disambiguation; Italian; SoundChoice;

   Abstract : Text-To-Speech systems are challenged by the presence of homographs, words that have more than one possible pronunciation. Rule-based approaches are often still the preferred solution to this issue in the industry. READ MORE

5. 4. Grounding of distrubution grids : High impedancegrounding compared to solid grounding with Fault Current Limiter

   University essay from

   Author : Maria Kättström; [2017]
   Keywords : ;

   Abstract : Today cables replace overhead lines in distribution systems and cause higher system capacitance and higher capacative fault currents. This fault current, in the fault location, is limited by a Petersén coil and a resistance in parallel when a fault occurs in so called “high impedance grounded systems” which are commonly used in Europe.

6. 5. The Sustainability related opportunities and challenges with various transformer insulation fluids and business case on re-refining

   University essay from KTH/Skolan för kemivetenskap (CHE)

   Author : Ibrahim Gharib Ali Jalal; Abdulbasit Abdulaziz Ali; [2017]
   Keywords : Transformer oils; LCA; Re-refining; Business case; Sustainability;

   Abstract : Transformers are electrical devices used in practice to increase or decrease voltages. Transformers are of various sizes and used mainly in power distribution. To provide cooling and insulation, transformer oils are used together with cellulose that acts as a solid insulation. READ MORE
